36860669cc socket: reject over-long proxy response line
fixes a one byte stack overflow when using RSYNC_PROXY with a
malicious proxy.

Reach: only when RSYNC_PROXY is set and a malicious or MITM'd
proxy returns the pathological response.  The byte written is
always '\0' and the attacker doesn't choose the offset, so impact
is corruption of one adjacent stack byte and possible later
misbehaviour or crash -- no information disclosure beyond the
existing rprintf of buffer contents.

0beceb95ac rsync.h: lower MAX_WIRE_DEL_STAT to avoid signed-int overflow in read_del_stats
read_del_stats() in main.c accumulates 5 wire-supplied counts into
the int32 stats.deleted_files field:

    stats.deleted_files  = read_varint_bounded(..., MAX_WIRE_DEL_STAT, ...);
    stats.deleted_files += stats.deleted_dirs     = ...;
    stats.deleted_files += stats.deleted_symlinks = ...;
    stats.deleted_files += stats.deleted_devices  = ...;
    stats.deleted_files += stats.deleted_specials = ...;

With the previous MAX_WIRE_DEL_STAT = 2^30 (1.07 GB) the worst-case
sum is 5 * 2^30 = 5.37 GB; three maximal values already exceed
INT32_MAX = 2.15 GB on the third "+=", triggering signed integer
overflow (C99 6.5/5 -- undefined behaviour, the compiler may assume
it cannot happen and elide subsequent checks).

The bound was introduced in f0155902 ("defence-in-depth: bound
wire-supplied counts and lengths") with a commit message claiming
"per-summand cap so the total can't overflow", but 2^30 * 5 does
overflow.  Lower the per-summand cap to 2^28 (= 268M) so the worst
case is 5 * 2^28 = 1.34 GB < INT32_MAX with margin.  2^28 deletions
per category is still vastly above any plausible real transfer.

f406c780ec popt: fix poptDupArgv strlcpy size argument
The bundled popt 1.18 (rsync 3.2.7) calls strlcpy(dst, argv[i], nb)
inside the per-arg loop in poptDupArgv(), where nb is the TOTAL
allocation size — not the remaining bytes after dst has advanced.
The actual write was always within the malloc'd buffer, so it was
silent on older glibcs, but glibc 2.39+ fortified strlcpy compares
the size argument against __bos(dst) and aborts with "*** buffer
overflow detected ***" once dst passes through any bytes.

That broke ~15 tests on Ubuntu 24.04 / glibc 2.39 in CI (any test
spawning a child rsync via popt's argv duplication path). Pass the
remaining bytes (end_buf - dst) so the size argument matches reality.

Master fixed the same bug differently in popt 1.19 (4c8683c8 "update
to popt 1.19") by switching to stpcpy, but pulling that 1500-line
refresh into a security backport is heavier than warranted.

259e04f923 ci: update RSYNC_EXPECT_SKIPPED for 3.2.7 backport baseline
The macOS / Cygwin expected-skipped lists in 3.4.x master assume
features that are present on master but not on 3.2.7 (e.g.
open-noatime semantics) and don't account for new tests added by
the May 2026 sec-patches that get skipped on these platforms
(daemon-chroot-acl, *-symlink-race, sender-flist-symlink-leak).
Realign each list with what the platform actually skips on this
backport branch so RSYNC_EXPECT_SKIPPED matches.

9354f27f9d exclude: fix crashes with fortified strlcpy()
Fortified (-D_FORTIFY_SOURCE=2 for gcc) builds make strlcpy() crash when
its third parameter (size) is larger than the buffer:
  $ rsync -FFXHav '--filter=merge global-rsync-filter' Align-37-43/ xxx
  sending incremental file list
  *** buffer overflow detected ***: terminated

It's in the exclude code in setup_merge_file():
  strlcpy(y, save, MAXPATHLEN);

Note the 'y' pointer was incremented, so it no longer points to memory
with MAXPATHLEN "owned" bytes.

Fix it by remembering the number of copied bytes into the 'save' buffer
and use that instead of MAXPATHLEN which is clearly incorrect.

Fixes #511.

3ac8349e07 defence-in-depth: receiver block-index bounds + read_delay_line null check
Two assorted audit findings:

  - receive_data() never bounds-checked the block index returned
    by recv_token() against sum.count before computing offset2
    and feeding it to map_ptr(). An out-of-bounds index from a
    hostile sender produces invalid memory access. Add a
    sum.count bounds check.

  - read_delay_line()'s strchr() call could return NULL when no
    space was found, but the code unconditionally added 1 to the
    result before dereferencing. Low impact (just a disconnect on
    exit of the client-specific forked process) but the NULL
    deref is real. Guard the NULL.

Both reported by Joshua Rogers.

816aa32059 defence-in-depth: guard cumulative snprintf against length underflow
Two cumulative-snprintf patterns in log.c (rsyserr) and main.c
(output_itemized_counts) had the shape

    len = snprintf(buf, sizeof buf, ...);
    len += snprintf(buf+len, sizeof buf - len, ...);

with no guard between calls. snprintf returns the would-have-been
length on truncation, so a truncated first call leaves
"sizeof buf - len" as a negative-then-promoted-to-size_t value,
underflowing into a huge size_t and writing past buf.

Realistic exposure is small in both cases (log header well under
buffer, only ~5 itemized iterations writing ~25 chars each into a
1024-byte buffer) but the defect class matches bb0a8118 and the
fix is cheap. Guard before each subsequent call.

f50c1d59c4 defence-in-depth: bound wire-supplied counts and lengths
Multiple receiver-side fields read from the wire were trusted
without upper-bound checks. A hostile peer could either request
extreme allocations (DoS via --max-alloc) or, on platforms where
read_varint returned a negative value, push ~SIZE_MAX through the
size_t conversion to wrap downstream length checks.

Introduce read_int_bounded(), read_varint_bounded() and
read_varint_size() in io.c so wire-derived integer ranges are
checked at the read site rather than scattered across each
caller, with RERR_PROTOCOL on out-of-range input.

Apply the bounded primitives to:
  - sum->count (checksum count -- previously could overflow
    (size_t)count * xfer_sum_len on 32-bit with raised max-alloc)
  - xattrs: count, name_len, datum_len, plus rel_pos overflow
    detect to stop chain wrapping the num accumulator
  - acls: ida-entry count
  - flist: file mode S_IFMT validation, modtime_nsec range check
  - delete-stat counters in main: per-summand cap so the total
    can't overflow a signed 32-bit accumulator

Reporters include Joshua Rogers (checksum-count overflow finding).

74ea276900 clientserver: fix hostname ACL bypass when using daemon chroot
On an rsync daemon configured with "daemon chroot", the reverse-DNS
lookup of the connecting client was performed *after* the chroot
had been entered. If the chroot did not contain the files glibc
needs for resolution (/etc/resolv.conf, /etc/nsswitch.conf,
/etc/hosts, NSS service modules), the lookup failed and
client_name() returned "UNKNOWN". Hostname-based deny rules
("hosts deny = *.evil.example") therefore could not match, and
an attacker controlling their PTR record could connect from a
hostname the administrator had intended to deny. IP-based ACLs
were unaffected.

Do the reverse DNS lookup before chroot/setuid; client_name()
caches its result, so the post-chroot call uses the cached value
and hostname-based ACLs work even when DNS is unavailable
post-chroot.

Adds testsuite/daemon-chroot-acl.test as end-to-end regression
coverage. The test sets up an empty chroot directory, configures
"hosts deny = <localhost-resolved-name>" with daemon chroot, and
asserts the connection is refused with @ERROR access denied.
Uses unshare --user --map-root-user for non-root CAP_SYS_CHROOT;
skips cleanly on non-Linux or when user namespaces aren't
available.

0a5fa00fdc receiver: add parent_ndx<0 guard, mirroring 797e17f
Commit 797e17f ("fixed an invalid access to files array") added a
parent_ndx < 0 guard to send_files() in sender.c, but the visually-
identical block in recv_files() in receiver.c was not updated. A
malicious rsync:// server can therefore drive any connecting client
into the same out-of-bounds dir_flist->files[-1] read followed by a
file_struct dereference in f_name() one line later.

Reach: protocol-30+ default (inc_recurse) makes flist.c:2745 set
parent_ndx = -1 on the first received flist when the sender omits a
leading "." entry; rsync.c flist_for_ndx() does not reject ndx == 0
in that state because the range check evaluates 0 < 0 = false; and
read_ndx_and_attrs() only validates ndx with the ITEM_TRANSFER bit
set, so iflags=ITEM_IS_NEW (or any other non-transfer iflag word)
bypasses the check.

Apply the same guard receiver-side. Confirmed: the same PoC (a
minimal Python rsyncd that handshakes with CF_INC_RECURSE, sends a
no-leading-"." flist, and emits ndx=0 with ITEM_IS_NEW) crashes
unpatched 3.4.2 with SEGV_MAPERR si_addr=0x4101a-class in the
receiver child; with this guard it exits cleanly with code 2
(RERR_PROTOCOL).

The attack surface delta over the sender variant is large:
the original was malicious-client -> daemon, this is
malicious-server -> any rsync client doing a normal rsync://
or remote-shell pull.

4255413e0c testsuite: cover 'refuse options = compress' for the daemon
Add a daemon-refuse-compress test that builds a module configured with
'refuse options = compress' and asserts that:
  1. an attempted -z transfer to that module fails with an error
     mentioning --compress, and
  2. the same transfer without -z still succeeds.

This pins down the documented way to disable all compression on a
daemon, which previously had no automated coverage.

901041dddc token: harden compressed-token decoding against integer overflow
The receiver's three compressed-token decoders --
recv_deflated_token (zlib), recv_zstd_token, and
recv_compressed_token (lz4) -- accumulated rx_token (a 32-bit
signed counter) without overflow checking. A malicious sender
could craft a compressed-token stream that walked rx_token past
INT32_MAX, with careful manipulation leaking process memory
contents to the wire (environment variables, passwords, heap
pointers, library pointers -- significantly weakening ASLR
and facilitating further exploitation).

Cap rx_token at MAX_TOKEN_INDEX = 0x7ffffffe. Fold the
bookkeeping into recv_compressed_token_num() and
recv_compressed_token_run() shared by all three decoders. Reject
negative or out-of-range token values explicitly. Also cap the
simple_recv_token literal-block length at the source: any
wire-supplied length > CHUNK_SIZE is ill-formed (the matching
simple_send_token never writes a chunk larger than CHUNK_SIZE),
so reject before looping on attacker-controlled bytes.

Reach: an authenticated daemon connection with compression
enabled (the default for protocols >= 30 when both peers
advertise it). Disabling compression on the daemon
("refuse options = compress" in rsyncd.conf) is the available
workaround.

7c8a647c2e testsuite: end-to-end regression test for chdir-symlink-race
testsuite/chdir-symlink-race.test runs an actual rsync daemon
(via RSYNC_CONNECT_PROG to avoid the network) configured with
"use chroot = no", plants a symlink at module/subdir -> ../outside,
and runs four flavours of attacker-shaped transfer (single-file
poc_chmod, -r push into the symlinked subdir with --size-only and
without, -r push into the module root). All four must leave the
outside-the-module sentinel file's mode AND content unchanged.

Portability:
  - file_mode() helper falls back to BSD stat -f %Lp when GNU
    stat -c %a is unavailable (macOS, FreeBSD).
  - Pre-saved pristine copy + cmp(1) replaces sha1sum, which
    differs across platforms (sha1sum / shasum / sha1).

Tests are kept running as root in the user-namespace re-exec
wrapper used by symlink-race tests so the daemon's setuid path
doesn't drop into the test user's identity (which on Linux
would mean the chmod-escape code path can't trigger because
the test user doesn't have CAP_FOWNER over the outside file).

a277a06b10 util1+syscall: secure copy_file source/dest opens; bare-path defence-in-depth
Three related codex audit findings:

  Finding 3a: copy_file()'s source open in util1.c used
  do_open_nofollow(), which only rejects a final-component
  symlink. A parent-component symlink (e.g. --copy-dest=cd where
  cd -> /outside) follows freely and reads outside the module.
  Route through secure_relative_open() with O_NOFOLLOW.

  Finding 3b: generator.c's in-place backup-file create still
  used a bare do_open with O_CREAT, leaving a tiny but reachable
  parent-symlink window between the secure unlink (already
  through do_unlink_at) and the create. Add do_open_at() that
  goes through a secure parent dirfd, and route the call site
  through it.

  Finding 3c: copy_file()'s destination open in
  unlink_and_reopen() had the same bare-do_open pattern; route
  through do_open_at as well.

Adds testsuite/copy-dest-source-symlink.test and
testsuite/bare-do-open-symlink-race.test as regression coverage
for both attack shapes.

39b3074a1a syscall: add symlink-race-safe do_*_at() wrappers and harden secure_relative_open
Add the rest of the path-based syscall wrappers and migrate every
receiver-side caller:
  - do_lchown_at, do_rename_at, do_mkdir_at, do_symlink_at,
    do_mknod_at, do_link_at, do_unlink_at, do_rmdir_at,
    do_utimensat_at, do_stat_at, do_lstat_at

Same shape as do_chmod_at: open each parent under
secure_relative_open(), call the *at() variant against the dirfd,
fall through to the bare path-based syscall in non-daemon /
chrooted / absolute-path / no-parent cases. macOS's
setattrlist-based set_times tier is also routed through the
utimensat_at path on daemon-no-chroot.

Hardenings to secure_relative_open() itself:
  - confine basedir resolution under the same kernel mechanism
    used for relpath (basedirs from --copy-dest / --link-dest are
    sender-controllable in daemon mode)
  - reject any '..' component (bare '..', 'foo/..', 'subdir/..')
    so the per-component O_NOFOLLOW fallback can't escape
  - return the dirfd we built up from the per-component fallback
    when the caller passed O_DIRECTORY (otherwise every do_*_at
    failed with EINVAL on platforms without RESOLVE_BENEATH)

Adds testsuite/alt-dest-symlink-race.test and
testsuite/secure-relpath-validation.test (with t_secure_relpath
helper) as regression coverage for the new hardenings.

d22b6bc7d1 util1: secure change_dir() against symlink-race chdir-escape
The receiver's chdir(2) into a destination subdirectory followed
attacker-planted symlinks at every path component. Once CWD
escaped the module, every subsequent path-relative syscall (open,
chmod, lchown, ...) inherited the escape -- defeating
secure_relative_open's RESOLVE_BENEATH anchor against AT_FDCWD,
since the anchor itself was now outside the module.

Route change_dir's relative target through secure_relative_open()
and fchdir() to the resulting dirfd in am_daemon && !am_chrooted
mode, so the chdir step itself can no longer follow a parent-
symlink. Same treatment applied to the CD_SKIP_CHDIR /
set_path_only path so it also can't follow attacker symlinks
during path tracking.

Adds testsuite/sender-flist-symlink-leak.test covering the
sender-side flist resolution variant of the same primitive.

24852cda3d syscall+receiver: secure receiver-side do_chmod against symlink-race TOCTOU
CVE-2026-29518's fix routed the receiver's open() through
secure_relative_open(), but every other path-based syscall the
receiver runs on sender-controllable paths is vulnerable to the
same TOCTOU primitive. This commit closes the chmod variant.

Add do_chmod_at() that opens the parent of fname under
secure_relative_open() and uses fchmodat() against the resulting
dirfd. Gate the secure path on am_daemon && !am_chrooted (the same
gate use_secure_symlinks already uses for the receiver basis-file
open), so non-daemon callers and chrooted daemons keep the original
do_chmod() fast path.

Migrate the receiver-side do_chmod() call sites in delete.c,
generator.c, rsync.c, and xattrs.c.

Adds testsuite/chmod-symlink-race.test (with t_chmod_secure helper)
as regression coverage.

99b36291d0 sender: fix read-path TOCTOU by opening from module root (CVE-2026-29518)
The sender's file open was vulnerable to the same TOCTOU symlink
race as the receiver-side basis-file open. change_pathname() calls
chdir() into subdirectories, which follows symlinks; an attacker
could race to swap a directory for a symlink between the chdir and
the file open, allowing reads of privileged files through the
daemon.

Reconstruct the full relative path (F_PATHNAME + fname) and open
via secure_relative_open() from the trusted module_dir, which
walks each path component without following symlinks. This is
independent of CWD, so the chdir race is neutralised.

1a5ad81add syscall+clientserver: am_chrooted and use_secure_symlinks for daemon-no-chroot (CVE-2026-29518)
CVE-2026-29518: an rsync daemon configured with "use chroot = no"
is exposed to a TOCTOU race on parent path components. A local
attacker with write access to a module can replace a parent
directory component with a symlink between the receiver's check
and its open(), redirecting reads (basis-file disclosure) and
writes (file overwrite) outside the module. Under elevated daemon
privilege this allows privilege escalation. Default
"use chroot = yes" is not exposed.

Add secure_relative_open() in syscall.c. It walks the parent
components under RESOLVE_BENEATH (Linux 5.6+) /
O_RESOLVE_BENEATH (FreeBSD 13+, macOS 15+) / per-component
O_NOFOLLOW elsewhere, anchored at a trusted dirfd, so a parent-
symlink swap is rejected by the kernel. Route the receiver's
basis-file open in receiver.c through it when use_secure_symlinks
is set in clientserver.c rsync_module().

2b3f8aacc7 testsuite: skip symlink-dirlink-basis on platforms without RESOLVE_BENEATH
secure_relative_open() has a kernel-enforced "stay below dirfd" path
on Linux 5.6+ (openat2 RESOLVE_BENEATH) and FreeBSD 13+ (openat
O_RESOLVE_BENEATH). On Solaris, OpenBSD, NetBSD, and Cygwin the code
falls back to the per-component O_NOFOLLOW walk, which by design
rejects every directory symlink in the path -- the very case this
test exercises. Mark the test skipped there rather than have it
fail with a known regression that's tracked separately.

macOS is intentionally not in the skip list: although it does not
have O_RESOLVE_BENEATH either, the test passes there in practice;
investigation of the underlying reason is left as follow-up.

61d987c54a syscall: also use O_RESOLVE_BENEATH on FreeBSD and MacOS
FreeBSD and MacOS have O_RESOLVE_BENEATH as an openat() flag with the same
"must not escape dirfd" semantics as Linux's RESOLVE_BENEATH. The
kernel rejects ".." escapes, absolute symlinks, and symlinks whose
target lies outside dirfd, while still following symlinks that
resolve within it -- the same trade-off that fixes issue #715 on
Linux.

Add a parallel BSD path in secure_relative_open(), gated on
declared. Unlike Linux, BSD doesn't have the header/runtime split
where the symbol can exist without kernel support, so no runtime
fallback is needed: if the flag compiles in, the kernel honours it.

OpenBSD and NetBSD have no equivalent kernel primitive and continue
to use the existing per-component O_NOFOLLOW walk; issue #715
remains visible on those platforms (a userland resolver or
unveil(2)-based fence would be follow-up work).

72d1cf1c28 syscall: use openat2(RESOLVE_BENEATH) on Linux for secure_relative_open
The CVE fix in commit c35e283 made secure_relative_open() walk every
component of relpath with O_NOFOLLOW. That blocks every symlink in the
path, which is stricter than the threat model required: legitimate
directory symlinks within the destination tree (e.g. when using -K /
--copy-dirlinks) are also rejected, breaking delta transfers with
"failed verification -- update discarded".  See issue #715.

On Linux 5.6+, openat2(RESOLVE_BENEATH | RESOLVE_NO_MAGICLINKS) gives
us exactly what we want: the kernel rejects any resolution that would
escape the starting directory (via "..", absolute paths, or symlinks
pointing outside dirfd) while still following symlinks that resolve
within it. /proc magic-links are blocked too.

Use openat2 first; fall back to the existing per-component O_NOFOLLOW
walk on ENOSYS (kernel < 5.6). The lexical "../" checks at the head
of the function are kept as defense in depth. The Linux gate is
plain #ifdef __linux__: the runtime ENOSYS fallback covers the only
case that actually matters (header present + old kernel), and any
Linux build environment without linux/openat2.h will fail with a
clear "no such file" error rather than silently disabling the
protection.

Verified manually that openat2(RESOLVE_BENEATH) blocks all four
escape patterns (absolute symlink, ../ symlink, lexical .., absolute
path) while allowing direct and within-tree symlinks. The new
testsuite/symlink-dirlink-basis.test (taken from PR #864 by Samuel
Henrique) exercises the issue #715 regression and passes; full
make check passes 47/47.

9ba21f638c testsuite/xattrs: ignore SUNWattr_* in the Solaris xls helper
The Solaris xls() function listed every entry in the file's xattr
directory, which on Solaris includes OS-managed SUNWattr_ro and
SUNWattr_rw pseudo-attributes. SUNWattr_rw embeds the file creation
time, so its bytes naturally differ between the source and destination
files, making the xattrs and xattrs-hlink tests fail with diffs that
have nothing to do with rsync.

Rsync's own listxattr wrapper already filters these out
(lib/sysxattrs.c), so the right fix is to filter them in the test
display too. Other platforms are unaffected because each has its own
xls() branch in the case statement.

With the test now actually passing on Solaris, drop the CI hack that
overwrote testsuite/xattrs.test with a skip stub.

acf4b7b839 call tzset() before chroot to cache timezone data
localtime/localtime_r need /etc/localtime for timezone info.
After chroot this file is inaccessible, causing log timestamps
to fall back to UTC. Calling tzset() before chroot ensures the
timezone data is cached by glibc for subsequent calls.

968d4c0cd0 xattrs: fixed count in qsort
this fixes the count passed to the sort of the xattr list. This issue
was reported here:

https://www.openwall.com/lists/oss-security/2026/04/16/2

the bug is not exploitable due to the fork-per-connection design of
rsync, the attack is the equivalent of the user closing the socket
themselves.

d69162dbf4 zero all new memory from allocations
Change my_alloc() to use calloc instead of malloc so all fresh
allocations return zeroed memory. Also zero the expanded portion
in expand_item_list() after realloc, since it knows both old and
new sizes. This gives more predictable behaviour in case of bugs
where uninitialised or stale memory is accidentally accessed.

cad6aab534 fix signed integer overflow in proxy protocol v2 header parsing
The len field in the proxy v2 header was declared as signed char,
allowing a negative size to bypass the validation check and cause
a stack buffer overflow when passed to read_buf() as size_t.

This bug was reported by John Walker from ZeroPath, many thanks for
the clear report!

With the current code this bug does not represent a security issue as
it only results in the exit of the forked process that is specific to
the attached client, so it is equivalent to the client closing the
socket, so no CVE for this, but it is good to fix it to prevent a
future issue.

c822d0c404 Fix glibc-2.43 constness warnings
Glibc 2.43 added C23 const-preserving overloads to various string functions,
which change the return type depending on the constness of the argument(s).
Currently this leads to warnings from calls to strtok() or strchr().
Fix this by properly declaring the respective variable types.

f8d8bba793 fix uninitialized mul_one in AVX2 checksum and add SIMD checksum test
The AVX2 get_checksum1_avx2_64() read mul_one before initializing it,
which is undefined behavior. Replace the cmpeq/abs trick with
_mm256_set1_epi8(1) to match the SSSE3 and SSE2 versions.

Add a TEST_SIMD_CHECKSUM1 test mode that verifies all SIMD paths
(SSE2, SSSE3, AVX2, and the full dispatch chain) produce identical
results to the C reference, across multiple buffer sizes with both
aligned and unaligned buffers.

50f0add12a reject negative token values in compressed stream receivers
Validate that token numbers read from compressed streams are
non-negative. A negative token value would cause the return value
of recv_*_token() to become positive, which callers interpret as
literal data length, but no data pointer is set on this code path.

While this only causes the receiver to crash (which is process-isolated
and only affects the attacker's own connection), it's still undefined
behavior.

841ab71c7c configure.ac: check for xattr support both in libc and in -lattr
In 2015, the attr/xattr.h header was fully removed from upstream attr.

In 2020, rsync started preferring the standard header, if it exists:
https://github.com/RsyncProject/rsync/pull/22

But the fix was incomplete. We still looked for the getxattr function in
-lattr, and used it if -lattr exists. This was the case even if the
system libc was sufficient to provide the needed functions. Result:
overlinking to -lattr, if it happened to be installed for any other
reason.

```
checking whether to support extended attributes... Using Linux xattrs
checking for getxattr in -lattr... yes
```

Instead, use a different autoconf macro that first checks if the
function is available for use without any libraries (e.g. it is in
libc).

Result:

```
checking whether to support extended attributes... Using Linux xattrs
checking for library containing getxattr... none required
```

The point of the #ifdef is to build for the configured OFF_T; there is
no reason to redefine lseek/lseek64, which should have been found
via configure.

name: Test rsync version mixing on Ubuntu
# Runs the CURRENT test suite with two different rsync binaries: the freshly
# built ./rsync as the client/driver, and a committed OLD static binary
# (old_versions/rsync_<ver>) as the daemon / remote-shell peer. This exercises
# real version mixing over the wire -- more convincing than --protocol forcing,
# which only makes the current binary speak an old protocol.
#
# Direction is fixed: the current binary always drives (only it understands the
# new test scripts); the old binary is only ever the server/daemon side. The
# reverse (old client driving new scripts) is not possible -- but one test,
# reverse-daemon-delta, swaps the roles internally (current build as the daemon,
# old binary as the client) to cover the backward-compat direction: a current
# daemon serving the installed base of old clients.
#
# The per-version manifest testsuite/expect/rsync_<ver>.expect lists exactly
# which tests run and each one's expected outcome (pass/skip/fail/xfail), so an
# old peer's known feature gaps are recorded rather than treated as breakage.
#
# All peers run in a SINGLE job (looped, not a matrix) so the PR shows one check
# line rather than one per version. Each peer/transport is a foldable ::group::
# in the log, and a failure annotates which peer/transport broke.

# NEWS for rsync 3.4.3 (20 May 2026)
## Changes in this version:
### SECURITY FIXES:
Six CVEs are fixed in this release. All six are assigned by
VulnCheck as CNA. Affected versions are 3.4.2 and earlier in every
case. Three of the six (CVE-2026-29518, CVE-2026-43617,
CVE-2026-43619) require non-default daemon configuration to reach:
the first and third need `use chroot = no` for a module, the second
needs `daemon chroot = ...` set in rsyncd.conf. Two (CVE-2026-43618,
CVE-2026-43620) are reachable from a normal pull or a normal
authenticated daemon connection. The sixth (CVE-2026-45232) is
reachable only when `RSYNC_PROXY` is set and the proxy (or a MITM)
returns a pathological response. Many thanks to the external
researchers who reported these issues.
- CVE-2026-29518 (CVSS v4.0 7.3, HIGH): TOCTOU symlink race condition
allowing local privilege escalation in daemon mode without chroot.
An rsync daemon configured with "use chroot = no" was exposed to a
time-of-check / time-of-use race on parent path components: a local
attacker with write access to a module could replace a parent
directory component with a symlink between the receiver's check and
its open(), redirecting reads (basis-file disclosure) and writes
(file overwrite) outside the module. Default "use chroot = yes" is
not exposed. `secure_relative_open()` (added in 3.4.0 for
CVE-2024-12086) was previously unused in the daemon-no-chroot
case; the fix enables it there and reroutes the sender's
read-path opens through it. Reported by Nullx3D (Batuhan Sancak),
Damien Neil and Michael Stapelberg.
- CVE-2026-43617 (CVSS v3.1 4.8, MEDIUM): Hostname/ACL bypass on an
rsync daemon configured with `daemon chroot = /X` in rsyncd.conf
when the chroot tree lacks DNS resolution support. The
reverse-DNS lookup of the connecting client was performed *after*
the daemon chroot had been entered; if /X did not contain the
libc resolver fixtures (`/etc/resolv.conf`, `/etc/nsswitch.conf`,
`/etc/hosts`, NSS service modules) the lookup failed and the
connecting hostname was set to "UNKNOWN", causing hostname-based
deny rules to silently fail open. IP-based ACLs are unaffected.
The per-module `use chroot` setting is unrelated to this issue.
The fix performs the lookup before entering the daemon chroot.
Reported by MegaManSec.
- CVE-2026-43618 (CVSS v3.1 8.1, HIGH): Integer overflow in the
compressed-token decoder enabling remote memory disclosure to an
authenticated daemon peer. The receiver accumulated a 32-bit
signed counter without overflow checking; a malicious sender could
trigger an overflow that, with careful manipulation, leaked process
memory contents to the attacker -- environment variables,
passwords, heap and library pointers -- significantly weakening
ASLR. The fix bounds the counter and adds wire-input validation in
several adjacent places (defence-in-depth). Workaround for older
releases: `refuse options = compress` in rsyncd.conf. Reported by
Omar Elsayed.
- CVE-2026-43619 (CVSS v3.1 6.3, MEDIUM): Symlink races on path-based
system calls in "use chroot = no" daemon mode (generalisation of
CVE-2026-29518). Earlier fixes for symlink races on the receiver's
open() call missed the same race class on every other path-based
system call: chmod, lchown, utimes, rename, unlink, mkdir, symlink,
mknod, link, rmdir and lstat. The fix routes each affected
path-based syscall through a parent dirfd opened under
RESOLVE_BENEATH-equivalent kernel-enforced confinement (openat2 on
Linux 5.6+, O_RESOLVE_BENEATH on FreeBSD 13+ and macOS 15+,
per-component O_NOFOLLOW walk elsewhere). Default "use chroot =
yes" is not exposed. Reported by Andrew Tridgell as a follow-on
audit of CVE-2026-29518.
- CVE-2026-43620 (CVSS v3.1 6.5, MEDIUM): Out-of-bounds read in the
receiver's recv_files() enabling remote denial-of-service of any
client pulling from a malicious server (incomplete fix of commit
797e17f). The earlier parent_ndx<0 guard added to send_files() was
not applied to the visually-identical block in recv_files(). A
malicious rsync server can drive any connecting client into a
deterministic SIGSEGV by setting CF_INC_RECURSE in the
compatibility flags and sending a crafted file list and transfer
record. inc_recurse is the protocol-30+ default, so no special
options are required on the victim. Workaround for older
releases: `--no-inc-recursive` on the client. Reported by Pratham
Gupta.
- CVE-2026-45232 (CVSS v3.1 3.1, LOW): Off-by-one out-of-bounds stack
write in the rsync client's HTTP CONNECT proxy handler
(`establish_proxy_connection()` in `socket.c`). After issuing the
CONNECT request, rsync read the proxy's first response line one
byte at a time into a 1024-byte stack buffer with the bound
`cp < &buffer[sizeof buffer - 1]`. If the proxy (or a MITM in
front of it) returned 1023+ bytes on that first line without a
newline terminator, `cp` exited the loop pointing at a buffer slot
the loop never wrote, leaving `*cp` holding stale stack data from
the earlier `snprintf()` of the outgoing CONNECT request. The
post-loop logic then wrote a single `\0` one byte past the end of
the buffer on the stack. Reach is client-side only, and only when
`RSYNC_PROXY` is set so rsync tunnels an `rsync://` connection
through an HTTP CONNECT proxy. The written byte is always `\0`
and the offset is fixed by the buffer size, not attacker-chosen,
so this is not an arbitrary-write primitive: practical impact is
corruption of one adjacent stack byte and possible later
misbehaviour or crash. The fix detects the "buffer filled without
finding `\n`" case explicitly by position and refuses the response
with "proxy response line too long". Reported by Aisle Research
via Michal Ruprich (rsync-3.4.1-2.el10 QE).
In addition to the six CVE fixes, this release adds defence-in-depth
hardening on several adjacent paths: bounded wire-supplied counts and
lengths in flist/io/acls/xattrs, a guard against length underflow in
cumulative `snprintf()` callers, a parent block-index bounds check on
the receiver, a NULL check in `read_delay_line()`, a lower ceiling on
`MAX_WIRE_DEL_STAT` to avoid signed-int overflow in the
`read_del_stats()` accumulator, rejection of hyphen-prefixed
remote-shell hostnames (defence-in-depth against argv-injection in
tooling that forwards untrusted input into the hostspec position;
reported by Aisle Research via Michal Ruprich), and a NULL-check on
`localtime_r()` in `timestring()` to keep a malicious server from
crashing the client by advertising a file with an out-of-range
modtime.
### BUG FIXES:
- Fixed a regression introduced by the 3.4.0 secure_relative_open()
CVE fix where legitimate directory symlinks on the receiver side
(e.g. when using `-K` / `--copy-dirlinks`) caused "failed
verification -- update discarded" errors on delta transfers. The
old code rejected every symlink in the path with a per-component
`O_NOFOLLOW` walk; the receiver now uses kernel-enforced "stay
below dirfd" path resolution where available. Fixes #715.
### PORTABILITY / BUILD:
- secure_relative_open() now uses `openat2(RESOLVE_BENEATH |
RESOLVE_NO_MAGICLINKS)` on Linux 5.6+, and `openat()` with
`O_RESOLVE_BENEATH` on FreeBSD 13+ and macOS 15+ (Sequoia) /
iOS 18+. The kernel rejects ".." escapes, absolute symlinks, and
symlinks whose target lies outside the starting directory, while
still following symlinks that resolve within it -- the same
trade-off that fixes the issue #715 regression without weakening
the original CVE protection. Other platforms (Solaris, OpenBSD,
NetBSD, Cygwin) retain the previous per-component `O_NOFOLLOW`
walk; on those platforms the issue #715 regression remains
visible.
- testsuite/xattrs: ignore `SUNWattr_*` in the Solaris `xls`
helper.
### DEVELOPER RELATED:
- Added testsuite/symlink-dirlink-basis.test (taken from PR #864
by Samuel Henrique) covering the issue #715 regression and
several edge cases (`--backup`, `--inplace`, `--partial-dir`
with protocol < 29, top-level files). The test skips on
platforms without a RESOLVE_BENEATH equivalent.
- Added regression tests for the new security fixes:
`chmod-symlink-race.test`, `chdir-symlink-race.test`,
`bare-do-open-symlink-race.test`, `alt-dest-symlink-race.test`,
`copy-dest-source-symlink.test`, `sender-flist-symlink-leak.test`,
`secure-relpath-validation.test`, `daemon-chroot-acl.test` and
`daemon-refuse-compress.test`. The symlink-race tests skip on
Cygwin, Solaris, OpenBSD and NetBSD (no RESOLVE_BENEATH
equivalent on those platforms).
- runtests.py now errors early with a clear message when any of
the test helper programs (`tls`, `trimslash`, `t_unsafe`,
`t_chmod_secure`, `t_secure_relpath`, `wildtest`, `getgroups`,
`getfsdev`) are missing, instead of letting many tests fail with
confusing "not found" errors.
- Added OpenBSD and NetBSD CI jobs that run `make check` on those
platforms.
- Added Ubuntu 22.04 and AlmaLinux 8 CI workflows so future
backports to the two mainstream LTS families build and test on
the same CI surface as trunk.
- testsuite/protected-regular.test now runs unprivileged via
`unshare` with user-namespace UID mapping, falling back to skip
if `unshare`/`uidmap` is not available; previously it required
real root.
- Added `symlink-dirlink-basis` to the Cygwin CI's expected-skipped
list.
- Removed the old release system (replaced by the new release
script in 3.4.2).

# NEWS for rsync 3.4.2 (28 Apr 2026)
## Changes in this version:
### SECURITY RELATED:
Several security-relevant defects were reported and fixed since 3.4.1.
None were assigned a CVE — rsync's fork-per-connection design scopes
the impact of each of these to the attacker's own connection, which is
equivalent to the client closing the socket itself — but they are
fixed here as a matter of hygiene and to reduce the chances of a
future exploitable combination. Many thanks to the external
researchers who reported these issues.
- Fixed a signed integer overflow in the PROXY protocol v2 header
parser: a negative `len` field could bypass the size check and cause
a stack buffer overflow in `read_buf()`. Reported by John Walker of
ZeroPath.
- Fixed an invalid access to the files array. Reported by Calum
Hutton of Rapid7.
- Reject negative token values in the compressed-stream token
decoder; a negative value could cause callers to misinterpret a
missing data pointer as literal data. Reported by Will Sergeant.
- Fixed the element count passed to the xattr `qsort()` (see
https://www.openwall.com/lists/oss-security/2026/04/16/2).
- Fixed a buffer underflow in `clean_fname()`, and added a regression
test.
- Fixed an uninitialized `mul_one` in the AVX2 get_checksum1 path
(undefined behaviour), and added a SIMD-checksum self-test that
cross-checks SSE2, SSSE3 and AVX2 against the C reference on both
aligned and unaligned buffers.
- Fixed an uninitialized `buf1` on the first call to
`get_checksum2()` in the MD4 path (fixes #673).
- Zero all new memory from internal allocations: `my_alloc()` now uses
`calloc`, and `expand_item_list()` zeros the expanded portion after
`realloc`. This gives more predictable behaviour if stale or
uninitialised memory is ever accidentally read.
### BUG FIXES:
- Call `tzset()` before chroot so that log timestamps continue to
reflect the configured local timezone after the daemon chroots
(glibc needs `/etc/localtime`, which is unreachable post-chroot).
- Use the correct time when writing to the log file.
- Do not clear `DISPLAY` unconditionally.
- Fixed a Y2038 bug in `syscall.c` by replacing the `Int32x32To64`
macro (which truncates its arguments to 32 bits) with a plain
64-bit multiplication.
- Fixed ACL ID mapping for non-root users (closes #618).
- Fixed handling of objects with many xattrs on FreeBSD.
- Fixed `--open-noatime` not taking effect when opening regular
files: `O_NOATIME` is now also passed to `do_open_nofollow()`, which
has been used for regular files since the CVE fix "fixed symlink
race condition in sender".
- Ignore "directory has vanished" errors.
- Fixed the removal of multiple leading slashes.
- Added the missing `--dirs` long option.
- Fixed a segfault if `poptGetContext()` returns NULL (e.g. under
OOM) by not passing NULL to `poptReadDefaultConfig()`. Reported by
Ronnie Sahlberg; found with `malloc-fail-tester`.
- Fixed a build error on ia64 NonStop (which treats missing
prototypes as an error, not a warning).
- Fixed a flaky hardlinks test (fixes #735).
### ENHANCEMENTS:
- Added multi-threaded `zstd` compression, gated by a new
`--compress-threads=N` option, with validation and man-page
coverage.
- Documented the `temp dir` parameter in the rsyncd.conf man page
(fixes #820).
- Improved rendering of interior dashes in long-option names in
`md-convert` (perhaps fixes #686).
### PORTABILITY / BUILD:
- Fixed glibc 2.43 const-preserving overloads of `strtok()`,
`strchr()` etc. by declaring the affected locals with the right
constness. Contributed by Holger Hoffstätte.
- Converted the bundled zlib 1.2.8 from K&R-style function
definitions to ANSI prototypes, so it builds with clang 16+.
- Avoid using `bool` as an identifier; it is a keyword in C23.
- `configure.ac`: check for xattr functions in libc first and only
fall back to `-lattr`, avoiding spurious overlinking when `-lattr`
happens to be installed. Contributed by Eli Schwartz.
- Made the build reproducible by honouring `SOURCE_DATE_EPOCH` for
the manpage date.
- Removed obsolete `popt/findme.c` and `popt/findme.h` that upstream
popt 1.14 folded into `popt.c` (fixes #710). Contributed by Alan
Coopersmith.
### INTERNAL:
- Made many module-global variables `const` so they can live in
`.rodata` and enable additional compiler optimization.
### DEVELOPER RELATED:
- Replaced `runtests.sh` with `runtests.py`, a Python test runner
that supports `--valgrind` (with per-process log files so valgrind
output no longer interferes with output comparisons) and
`-j/--parallel` execution for roughly a 7× speed-up on typical
hardware.
- Added a SIMD checksum self-test and a `clean-fname-underflow`
regression test.
- Various CI fixes for macOS and Cygwin (including adding
`simd-checksum` to the expected-skipped lists on platforms without
SIMD), and tests now run on `ubuntu-latest`.
- removed support for the unmaintained rsync-patches archive
------------------------------------------------------------------------------
# NEWS for rsync 3.4.1 (16 Jan 2025)
Release 3.4.1 is a fix for regressions introduced in 3.4.0
## Changes in this version:
### BUG FIXES:
- fixed handling of -H flag with conflict in internal flag values
- fixed a user after free in logging of failed rename
- fixed build on systems without openat()
- removed dependency on alloca() in bundled popt
### DEVELOPER RELATED:
- fix to permissions handling in the developer release script

# NEWS for rsync 3.4.0 (15 Jan 2025)
Release 3.4.0 is a security release that fixes a number of important vulnerabilities.
For more details on the vulnerabilities please see the CERT report
https://kb.cert.org/vuls/id/952657
## Changes in this version:
### PROTOCOL NUMBER:
- The protocol number was changed to 32 to make it easier for
administrators to check their servers have been updated
### SECURITY FIXES:
Many thanks to Simon Scannell, Pedro Gallegos, and Jasiel Spelman at
Google Cloud Vulnerability Research and Aleksei Gorban (Loqpa) for
discovering these vulnerabilities and working with the rsync project
to develop and test fixes.
- CVE-2024-12084 - Heap Buffer Overflow in Checksum Parsing.
- CVE-2024-12085 - Info Leak via uninitialized Stack contents defeats ASLR.
- CVE-2024-12086 - Server leaks arbitrary client files.
- CVE-2024-12087 - Server can make client write files outside of destination directory using symbolic links.
- CVE-2024-12088 - --safe-links Bypass.
- CVE-2024-12747 - symlink race condition.
### BUG FIXES:
- Fixed the included popt to avoid a memory error on modern gcc versions.
- Fixed an incorrect extern variable's type that caused an ACL issue on macOS.
- Fixed IPv6 configure check
### INTERNAL:
- Updated included popt to version 1.19.
### DEVELOPER RELATED:
- Various improvements to the release scripts and git setup.
- Improved packaging/var-checker to identify variable type issues.
- added FreeBSD and Solaris CI builds
------------------------------------------------------------------------------
# NEWS for rsync 3.3.0 (6 Apr 2024)
## Changes in this version:
### BUG FIXES:
- Fixed a bug with `--sparse --inplace` where a trailing gap in the source
file would not clear out the trailing data in the destination file.
- Fixed an buffer overflow in the checksum2 code if SHA1 is being used for
the checksum2 algorithm.
- Fixed an issue when rsync is compiled using `_FORTIFY_SOURCE` so that the
extra tests don't complain about a strlcpy() limit value (which was too
large, even though it wasn't possible for the larger value to cause an
overflow).
- Add a backtick to the list of characters that the filename quoting needs to
escape using backslashes.
- Fixed a string-comparison issue in the internal handling of `--progress` (a
locale such as tr_TR.utf-8 needed the internal triggering of `--info` options
to use upper-case flag names to ensure that they match).
- Make sure that a local transfer marks the sender side as trusted.
- Change the argv handling to work with a newer popt library -- one that likes
to free more data than it used to.
- Rsync now calls `OpenSSL_add_all_algorithms()` when compiled against an older
openssl library.
- Fixed a problem in the daemon auth for older protocols (29 and before) if the
openssl library is being used to compute MD4 checksums.
- Fixed `rsync -VV` on Cygwin -- it needed a flush of stdout.
- Fixed an old stats bug that counted devices as symlinks.
### ENHANCEMENTS:
- Enhanced rrsync with the `-no-overwrite` option that allows you to ensure
that existing files on your restricted but writable directory can't be
modified.
- Enhanced the manpages to mark links with .UR & .UE. If your nroff doesn't
support these idioms, touch the file `.md2man-force` in the source directory
so that `md-convert` gets called with the `--force-link-text` option, and
that should ensure that your manpages are still readable even with the
ignored markup.
- Some manpage improvements on the handling of [global] modules.
- Changed the mapfrom & mapto perl scripts (in the support dir) into a single
python script named idmap. Converted a couple more perl scripts into python.
- Changed the mnt-excl perl script (in the support dir) into a python script.
### DEVELOPER RELATED:
- Updated config.guess (timestamp 2023-01-01) and config.sub (timestamp
2023-01-21).

Wildcards are not escaped in filename args, but they are escaped in options

If a script depends on the old arg behavior (perhaps because it quotes or
protects the args already, or perhaps because it expects arg splitting),
there are two easy ways to get things going with a modern rsync: either
`export RSYNC_OLD_ARGS=1` in the script's environment (perhaps in the script
itself) or add the option [`--old-args`](rsync.1#opt) to the rsync commands
that are run. See also the [ADVANCED USAGE](rsync.1#) section of rsync's

/*
* Android-specific helpers.
*
* openat2() usability probe
* -------------------------
* openat2(2) is invoked directly via syscall() because the C library lacked a
* wrapper for it for years. Under a seccomp filter that uses
* SECCOMP_RET_TRAP -- as the Android application sandbox does -- a disallowed
* syscall raises SIGSYS and *kills the process* rather than failing with
* ENOSYS, so inspecting errno after the call is too late. We therefore probe
* openat2() once, behind a temporary SIGSYS handler, so a trapped syscall is
* caught and secure_relative_open_linux() can fall back to the portable
* per-component O_NOFOLLOW resolver instead of the whole process dying.
*
* This is only needed on Android, so the probe body is compiled only there.
* __ANDROID__ is defined by Bionic's headers and reflects the *target*, not
* the build host: it is set both for NDK cross-compiles (from a Linux/macOS
* host) and for native Termux builds, and is unset on every other platform.
* That makes it a reliable compile-time switch for cross builds -- there is
* nothing to detect in configure. Everywhere else openat2() is never
* seccomp-trapped to SIGSYS (a missing syscall simply returns ENOSYS), so
* openat2_usable() collapses to a constant 1 with no run-time cost.

Handling the rsync SGML documentation
rsync documentation is now primarily in Docbook format. Docbook is an
SGML/XML documentation format that is becoming standard on free
operating systems. It's also used for Samba documentation.
The SGML files are source code that can be translated into various
useful output formats, primarily PDF, HTML, Postscript and plain text.
To do this transformation on Debian, you should install the
docbook-utils package. Having done that, you can say
docbook2pdf rsync.sgml
and so on.
On other systems you probably need James Clark's "sp" and "JadeTeX"
packages. Work it out for yourself and send a note to the mailing
list.

<para>rsync is a flexible program for efficiently copying files or
directory trees.
<para>rsync has many options to select which files will be copied
and how they are to be transferred. It may be used as an
alternative to ftp, http, scp or rcp.
<para>The rsync remote-update protocol allows rsync to transfer just
the differences between two sets of files across the network link,
using an efficient checksum-search algorithm described in the
technical report that accompanies this package.</para>

Probably the most common case of rsync usage is to copy files
to or from a remote machine using
<application>ssh</application> as a network transport. In
this situation rsync is a good alternative to

<para>
Note that in all cases (other than listing) at least one of the source

<para>
Any one invocation of rsync makes a copy in a single direction. rsync
currently has no equivalent of @command{ftp}'s interactive mode.
@cindex @sc{nfs}
@cindex network filesystems
@cindex remote filesystems
<para>
rsync's network protocol is generally faster at copying files than
network filesystems such as @sc{nfs} or @sc{cifs}. It is better to
run rsync on the file server either as a daemon or over ssh than
running rsync giving the network directory.

<question>
<para>
Why is rsync so much bigger when I build it with
<command>gcc</command>?
</para>
</question>
<answer>
<para>
On gcc, rsync builds by default with debug symbols
included. If you strip both executables, they should end
up about the same size. (Use <command>make
install-strip</command>.)
</para>
</answer>
</qandaentry>
<qandaentry>
<question>
<para>Is rsync useful for a single large file like an ISO image?</para>
</question>
<answer>
<para>
Yes, but note the following:
<para>
Background: A common use of rsync is to update a file (or set of files) in one location from a more
correct or up-to-date copy in another location, taking advantage of portions of the files that are
identical to speed up the process. (Note that rsync will transfer a file in its entirety if no copy
exists at the destination.)
<para>
(This discussion is written in terms of updating a local copy of a file from a correct file in a
remote location, although rsync can work in either direction.)
<para>
The file to be updated (the local file) must be in a destination directory that has enough space for
two copies of the file. (In addition, keep an extra copy of the file to be updated in a different
location for safety -- see the discussion (below) about rsync's behavior when the rsync process is
interrupted before completion.)
<para>
The local file must have the same name as the remote file being sync'd to (I think?). If you are
trying to upgrade an iso from, for example, beta1 to beta2, rename the local file to the same name
as the beta2 file. *(This is a useful thing to do -- only the changed portions will be
transmitted.)*
<para>
The extra copy of the local file kept in a different location is because of rsync's behavior if
interrupted before completion:
<para>
* If you specify the --partial option and rsync is interrupted, rsync will save the partially
rsync'd file and throw away the original local copy. (The partially rsync'd file is correct but
truncated.) If rsync is restarted, it will not have a local copy of the file to check for duplicate
blocks beyond the section of the file that has already been rsync'd, thus the remainder of the rsync
process will be a "pure transfer" of the file rather than taking advantage of the rsync algorithm.
<para>
* If you don't specify the --partial option and rsync is interrupted, rsync will throw away the
partially rsync'd file, and, when rsync is restarted starts the rsync process over from the
beginning.
<para>
Which of these is most desirable depends on the degree of commonality between the local and remote
copies of the file *and how much progress was made before the interruption*.
<para>
The ideal approach after an interruption would be to create a new file by taking the original file
and deleting a portion equal in size to the portion already rsync'd and then appending *the
remaining* portion to the portion of the file that has already been rsync'd. (There has been some
discussion about creating an option to do this automatically.)
The --compare-dest option is useful when transferring multiple files, but is of no benefit in
transferring a single file. (AFAIK)

# Old rsync version archive
Static rsync binaries built from historical release tags. Two uses:
1. **Cross-version behaviour checks** — confirming whether a behaviour a user
reported on an old release is version-specific or option-driven.
2. **The version-mixing test suite**`runtests.py --rsync-bin2=...` runs the
current code against one of these as the daemon / remote-shell peer; CI
(`.github/workflows/ubuntu-version-mix.yml`) does this for every binary
here against the per-version manifests in `testsuite/expect/`.
Binaries are **statically linked** so they run regardless of the host's
shared libraries, and named `rsync_<version>`:
| Binary | Version | Protocol | Notes |
|----------------|---------|----------|-----------------------------------------|
| `rsync_2.6.0` | 2.6.0 | 27 | 2004; needs autoconf regen (see below) |
| `rsync_3.0.0` | 3.0.0 | 30 | 2008 |
| `rsync_3.1.0` | 3.1.0 | 31 | 2013 |
| `rsync_3.1.3` | 3.1.3 | 31 | Ubuntu 18.04 / Debian buster era (2018) |
| `rsync_3.2.0` | 3.2.0 | 31 | 2020 (zstd/lz4/xxhash negotiation added)|
| `rsync_3.2.7` | 3.2.7 | 31 | 2022 |
| `rsync_3.3.0` | 3.3.0 | 31 | 2024 |
| `rsync_3.4.0` | 3.4.0 | 32 | 2025 |
| `rsync_3.4.1` | 3.4.1 | 32 | 2025 |
These are every `x.y.0` release from 2.6.0 (2004) onward plus a few point
releases. 2.6.0 is the practical floor: older tags need progressively more
porting to build on a current toolchain.
All built `--disable-openssl` and with `_FORTIFY_SOURCE` disabled (see below);
xxhash/zstd/lz4 are compiled in where the version supports them.
## Adding a version
```bash
./build_static.sh 3.2.7 # uses git tag v3.2.7
./build_static.sh 3.0.9 v3.0.9 # explicit tag if naming differs
```
The script checks out the tag into a throwaway `git worktree`, applies the
minimal patches needed to compile old sources on a modern toolchain, links
statically, verifies the result is static and reports the requested version,
then installs `rsync_<version>` here and removes the worktree.
Override the source repo with `RSYNC_REPO=/path/to/rsync ./build_static.sh ...`
(defaults to `../rsync.4`).
## Why the patches?
Modern GCC (>= 14, C23 default) and glibc reject things old rsync relied on.
`build_static.sh` handles these, each guarded so it's a no-op when not needed:
1. **K&R `lseek64()` redeclaration** in `syscall.c` clashes with glibc's real
prototype — removed.
2. **`gettimeofday()`** — glibc only has the 2-arg form; configure misdetects
the 1-arg form, so `HAVE_GETTIMEOFDAY_TZ` is forced on in `config.h`.
3. **C23 `()` == `(void)`** breaks K&R prototypes called with arguments
(`qsort` comparator, `pool->bomb`, etc.) — built with `-std=gnu11`.
4. Assorted modern `-Werror` promotions (incompatible pointer types, implicit
declarations) downgraded to warnings; bundled zlib/popt used to keep the
static link self-contained.
5. **OpenSSL (3.2+)** is disabled with `--disable-openssl`: linking
`libcrypto.a` statically drags in jitterentropy (`jent_*`) and zlib's
`uncompress` (OpenSSL's COMP module), which don't resolve here. OpenSSL only
provided optional MD4/MD5, which rsync implements natively, so checksum
behaviour is unaffected.
6. **`_FORTIFY_SOURCE` disabled** (`-U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=0`):
modern Ubuntu defaults it to `=3`, whose stricter object-size checks turn
latent (historically benign) over-reads in OLD rsync into hard
`*** buffer overflow detected ***` aborts when the binary runs as a
server/daemon — which made e.g. 3.1.3 and 3.2.7 unusable as peers. Disabling
it makes the archival binaries behave as the released versions did.
7. **Pre-3.0 tags (e.g. 2.6.0)** ship `configure.in`, not a generated
`configure`. The script runs `autoheader`/`autoconf` to generate it, after
neutralizing the `AC_CHECK_FUNCS(fn,,AC_LIBOBJ(lib/...))` fallbacks for
`inet_ntop`/`inet_pton`/`getaddrinfo`/`getnameinfo` — modern autoconf emits
broken shell for those never-taken branches (the funcs exist in glibc). It
also generates `proto.h` (no make rule in that era) and stubs the vendored
`lib/addrinfo.h` the tag dropped (modern glibc supplies `struct addrinfo`).
All guarded so they no-op on 3.x.
Newer versions may need fewer or different tweaks; if a build fails, the
script prints the first compiler errors from its log.

* lookup3.c, by Bob Jenkins, May 2006, Public Domain.
*
* These are functions for producing 32-bit hashes for hash table lookup.
* jlu32w(), jlu32l(), jlu32lpair(), jlu32b(), _JLU3_MIX(), and _JLU3_FINAL()
* are externally useful functions. Routines to test the hash are included
* if SELF_TEST is defined. You can use this free for any purpose. It's in
* the public domain. It has no warranty.
*
* You probably want to use jlu32l(). jlu32l() and jlu32b()
* hash byte arrays. jlu32l() is is faster than jlu32b() on
* little-endian machines. Intel and AMD are little-endian machines.
* On second thought, you probably want jlu32lpair(), which is identical to
* jlu32l() except it returns two 32-bit hashes for the price of one.
* You could implement jlu32bpair() if you wanted but I haven't bothered here.
*
* If you want to find a hash of, say, exactly 7 integers, do
* a = i1; b = i2; c = i3;
* _JLU3_MIX(a,b,c);
* a += i4; b += i5; c += i6;
* _JLU3_MIX(a,b,c);
* a += i7;
* _JLU3_FINAL(a,b,c);
* then use c as the hash value. If you have a variable size array of
* 4-byte integers to hash, use jlu32w(). If you have a byte array (like
* a character string), use jlu32l(). If you have several byte arrays, or
* a mix of things, see the comments above jlu32l().
*
* Why is this so big? I read 12 bytes at a time into 3 4-byte integers,
* then mix those integers. This is fast (you can do a lot more thorough
* mixing with 12*3 instructions on 3 integers than you can with 3 instructions
* on 1 byte), but shoehorning those bytes into integers efficiently is messy.

* This is reversible, so any information in (a,b,c) before _JLU3_MIX() is

*
* If four pairs of (a,b,c) inputs are run through _JLU3_MIX(), or through
* _JLU3_MIX() in reverse, there are at least 32 bits of the output that
* are sometimes the same for one pair and different for another pair.
* This was tested for:
* * pairs that differed by one bit, by two bits, in any combination
* of top bits of (a,b,c), or in any combination of bottom bits of
* (a,b,c).
* * "differ" is defined as +, -, ^, or ~^. For + and -, I transformed
* the output delta to a Gray code (a^(a>>1)) so a string of 1's (as
* is commonly produced by subtraction) look like a single 1-bit
* difference.
* * the base values were pseudorandom, all zero but one bit set, or
* all zero plus a counter that starts at zero.
*
* Some k values for my "a-=c; a^=ROTL32(c,k); c+=b;" arrangement that
* satisfy this are
* 4 6 8 16 19 4
* 9 15 3 18 27 15
* 14 9 3 7 17 3
* Well, "9 15 3 18 27 15" didn't quite get 32 bits diffing
* for "differ" defined as + with a one-bit base and a two-bit delta. I
* used http://burtleburtle.net/bob/hash/avalanche.html to choose
* the operations, constants, and arrangements of the variables.
*
* This does not achieve avalanche. There are input bits of (a,b,c)
* that fail to affect some output bits of (a,b,c), especially of a. The
* most thoroughly mixed value is c, but it doesn't really even achieve
* avalanche in c.
*
* This allows some parallelism. Read-after-writes are good at doubling
* the number of bits affected, so the goal of mixing pulls in the opposite
* direction as the goal of parallelism. I did what I could. Rotates
* seem to cost as much as shifts on every machine I could lay my hands
* on, and rotates are much kinder to the top and bottom bits, so I used
* rotates.

GNU GENERAL PUBLIC LICENSE
Version 3, 29 June 2007
Copyright (C) 2007 Free Software Foundation, Inc. &lt;<a href="https://fsf.org/">https://fsf.org/</a>&gt;
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The GNU General Public License is a free, copyleft license for
software and other kinds of works.
The licenses for most software and other practical works are designed
to take away your freedom to share and change the works. By contrast,
the GNU General Public License is intended to guarantee your freedom to
share and change all versions of a program--to make sure it remains free
software for all its users. We, the Free Software Foundation, use the
GNU General Public License for most of our software; it applies also to
any other work released this way by its authors. You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
them if you wish), that you receive source code or can get it if you
want it, that you can change the software or use pieces of it in new
free programs, and that you know you can do these things.
To protect your rights, we need to prevent others from denying you
these rights or asking you to surrender the rights. Therefore, you have
certain responsibilities if you distribute copies of the software, or if
you modify it: responsibilities to respect the freedom of others.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must pass on to the recipients the same
freedoms that you received. You must make sure that they, too, receive
or can get the source code. And you must show them these terms so they
know their rights.
Developers that use the GNU GPL protect your rights with two steps:
(1) assert copyright on the software, and (2) offer you this License
giving you legal permission to copy, distribute and/or modify it.
For the developers' and authors' protection, the GPL clearly explains
that there is no warranty for this free software. For both users' and
authors' sake, the GPL requires that modified versions be marked as
changed, so that their problems will not be attributed erroneously to
authors of previous versions.
Some devices are designed to deny users access to install or run
modified versions of the software inside them, although the manufacturer
can do so. This is fundamentally incompatible with the aim of
protecting users' freedom to change the software. The systematic
pattern of such abuse occurs in the area of products for individuals to
use, which is precisely where it is most unacceptable. Therefore, we
have designed this version of the GPL to prohibit the practice for those
products. If such problems arise substantially in other domains, we
stand ready to extend this provision to those domains in future versions
of the GPL, as needed to protect the freedom of users.
Finally, every program is threatened constantly by software patents.
States should not allow patents to restrict development and use of
software on general-purpose computers, but in those that do, we wish to
avoid the special danger that patents applied to a free program could
make it effectively proprietary. To prevent this, the GPL assures that
patents cannot be used to render the program non-free.
The precise terms and conditions for copying, distribution and
modification follow.
TERMS AND CONDITIONS
0. Definitions.
"This License" refers to version 3 of the GNU General Public License.
"Copyright" also means copyright-like laws that apply to other kinds of
works, such as semiconductor masks.
"The Program" refers to any copyrightable work licensed under this
License. Each licensee is addressed as "you". "Licensees" and
"recipients" may be individuals or organizations.
To "modify" a work means to copy from or adapt all or part of the work
in a fashion requiring copyright permission, other than the making of an
exact copy. The resulting work is called a "modified version" of the
earlier work or a work "based on" the earlier work.
A "covered work" means either the unmodified Program or a work based
on the Program.
To "propagate" a work means to do anything with it that, without
permission, would make you directly or secondarily liable for
infringement under applicable copyright law, except executing it on a
computer or modifying a private copy. Propagation includes copying,
distribution (with or without modification), making available to the
public, and in some countries other activities as well.
To "convey" a work means any kind of propagation that enables other
parties to make or receive copies. Mere interaction with a user through
a computer network, with no transfer of a copy, is not conveying.
An interactive user interface displays "Appropriate Legal Notices"
to the extent that it includes a convenient and prominently visible
feature that (1) displays an appropriate copyright notice, and (2)
tells the user that there is no warranty for the work (except to the
extent that warranties are provided), that licensees may convey the
work under this License, and how to view a copy of this License. If
the interface presents a list of user commands or options, such as a
menu, a prominent item in the list meets this criterion.
1. Source Code.
The "source code" for a work means the preferred form of the work
for making modifications to it. "Object code" means any non-source
form of a work.
A "Standard Interface" means an interface that either is an official
standard defined by a recognized standards body, or, in the case of
interfaces specified for a particular programming language, one that
is widely used among developers working in that language.
The "System Libraries" of an executable work include anything, other
than the work as a whole, that (a) is included in the normal form of
packaging a Major Component, but which is not part of that Major
Component, and (b) serves only to enable use of the work with that
Major Component, or to implement a Standard Interface for which an
implementation is available to the public in source code form. A
"Major Component", in this context, means a major essential component
(kernel, window system, and so on) of the specific operating system
(if any) on which the executable work runs, or a compiler used to
produce the work, or an object code interpreter used to run it.
The "Corresponding Source" for a work in object code form means all
the source code needed to generate, install, and (for an executable
work) run the object code and to modify the work, including scripts to
control those activities. However, it does not include the work's
System Libraries, or general-purpose tools or generally available free
programs which are used unmodified in performing those activities but
which are not part of the work. For example, Corresponding Source
includes interface definition files associated with source files for
the work, and the source code for shared libraries and dynamically
linked subprograms that the work is specifically designed to require,
such as by intimate data communication or control flow between those
subprograms and other parts of the work.
The Corresponding Source need not include anything that users
can regenerate automatically from other parts of the Corresponding
Source.
The Corresponding Source for a work in source code form is that
same work.
2. Basic Permissions.
All rights granted under this License are granted for the term of
copyright on the Program, and are irrevocable provided the stated
conditions are met. This License explicitly affirms your unlimited
permission to run the unmodified Program. The output from running a
covered work is covered by this License only if the output, given its
content, constitutes a covered work. This License acknowledges your
rights of fair use or other equivalent, as provided by copyright law.
You may make, run and propagate covered works that you do not
convey, without conditions so long as your license otherwise remains
in force. You may convey covered works to others for the sole purpose
of having them make modifications exclusively for you, or provide you
with facilities for running those works, provided that you comply with
the terms of this License in conveying all material for which you do
not control copyright. Those thus making or running the covered works
for you must do so exclusively on your behalf, under your direction
and control, on terms that prohibit them from making any copies of
your copyrighted material outside their relationship with you.
Conveying under any other circumstances is permitted solely under
the conditions stated below. Sublicensing is not allowed; section 10
makes it unnecessary.
3. Protecting Users' Legal Rights From Anti-Circumvention Law.
No covered work shall be deemed part of an effective technological
measure under any applicable law fulfilling obligations under article
11 of the WIPO copyright treaty adopted on 20 December 1996, or
similar laws prohibiting or restricting circumvention of such
measures.
When you convey a covered work, you waive any legal power to forbid
circumvention of technological measures to the extent such circumvention
is effected by exercising rights under this License with respect to
the covered work, and you disclaim any intention to limit operation or
modification of the work as a means of enforcing, against the work's
users, your or third parties' legal rights to forbid circumvention of
technological measures.
4. Conveying Verbatim Copies.
You may convey verbatim copies of the Program's source code as you
receive it, in any medium, provided that you conspicuously and
appropriately publish on each copy an appropriate copyright notice;
keep intact all notices stating that this License and any
non-permissive terms added in accord with section 7 apply to the code;
keep intact all notices of the absence of any warranty; and give all
recipients a copy of this License along with the Program.
You may charge any price or no price for each copy that you convey,
and you may offer support or warranty protection for a fee.
5. Conveying Modified Source Versions.
You may convey a work based on the Program, or the modifications to
produce it from the Program, in the form of source code under the
terms of section 4, provided that you also meet all of these conditions:
a) The work must carry prominent notices stating that you modified
it, and giving a relevant date.
b) The work must carry prominent notices stating that it is
released under this License and any conditions added under section
7. This requirement modifies the requirement in section 4 to
"keep intact all notices".
c) You must license the entire work, as a whole, under this
License to anyone who comes into possession of a copy. This
License will therefore apply, along with any applicable section 7
additional terms, to the whole of the work, and all its parts,
regardless of how they are packaged. This License gives no
permission to license the work in any other way, but it does not
invalidate such permission if you have separately received it.
d) If the work has interactive user interfaces, each must display
Appropriate Legal Notices; however, if the Program has interactive
interfaces that do not display Appropriate Legal Notices, your
work need not make them do so.
A compilation of a covered work with other separate and independent
works, which are not by their nature extensions of the covered work,
and which are not combined with it such as to form a larger program,
in or on a volume of a storage or distribution medium, is called an
"aggregate" if the compilation and its resulting copyright are not
used to limit the access or legal rights of the compilation's users
beyond what the individual works permit. Inclusion of a covered work
in an aggregate does not cause this License to apply to the other
parts of the aggregate.
6. Conveying Non-Source Forms.
You may convey a covered work in object code form under the terms
of sections 4 and 5, provided that you also convey the
machine-readable Corresponding Source under the terms of this License,
in one of these ways:
a) Convey the object code in, or embodied in, a physical product
(including a physical distribution medium), accompanied by the
Corresponding Source fixed on a durable physical medium
customarily used for software interchange.
b) Convey the object code in, or embodied in, a physical product
(including a physical distribution medium), accompanied by a
written offer, valid for at least three years and valid for as
long as you offer spare parts or customer support for that product
model, to give anyone who possesses the object code either (1) a
copy of the Corresponding Source for all the software in the
product that is covered by this License, on a durable physical
medium customarily used for software interchange, for a price no
more than your reasonable cost of physically performing this
conveying of source, or (2) access to copy the
Corresponding Source from a network server at no charge.
c) Convey individual copies of the object code with a copy of the
written offer to provide the Corresponding Source. This
alternative is allowed only occasionally and noncommercially, and
only if you received the object code with such an offer, in accord
with subsection 6b.
d) Convey the object code by offering access from a designated
place (gratis or for a charge), and offer equivalent access to the
Corresponding Source in the same way through the same place at no
further charge. You need not require recipients to copy the
Corresponding Source along with the object code. If the place to
copy the object code is a network server, the Corresponding Source
may be on a different server (operated by you or a third party)
that supports equivalent copying facilities, provided you maintain
clear directions next to the object code saying where to find the
Corresponding Source. Regardless of what server hosts the
Corresponding Source, you remain obligated to ensure that it is
available for as long as needed to satisfy these requirements.
e) Convey the object code using peer-to-peer transmission, provided
you inform other peers where the object code and Corresponding
Source of the work are being offered to the general public at no
charge under subsection 6d.
A separable portion of the object code, whose source code is excluded
from the Corresponding Source as a System Library, need not be
included in conveying the object code work.
A "User Product" is either (1) a "consumer product", which means any
tangible personal property which is normally used for personal, family,
or household purposes, or (2) anything designed or sold for incorporation
into a dwelling. In determining whether a product is a consumer product,
doubtful cases shall be resolved in favor of coverage. For a particular
product received by a particular user, "normally used" refers to a
typical or common use of that class of product, regardless of the status
of the particular user or of the way in which the particular user
actually uses, or expects or is expected to use, the product. A product
is a consumer product regardless of whether the product has substantial
commercial, industrial or non-consumer uses, unless such uses represent
the only significant mode of use of the product.
"Installation Information" for a User Product means any methods,
procedures, authorization keys, or other information required to install
and execute modified versions of a covered work in that User Product from
a modified version of its Corresponding Source. The information must
suffice to ensure that the continued functioning of the modified object
code is in no case prevented or interfered with solely because
modification has been made.
If you convey an object code work under this section in, or with, or
specifically for use in, a User Product, and the conveying occurs as
part of a transaction in which the right of possession and use of the
User Product is transferred to the recipient in perpetuity or for a
fixed term (regardless of how the transaction is characterized), the
Corresponding Source conveyed under this section must be accompanied
by the Installation Information. But this requirement does not apply
if neither you nor any third party retains the ability to install
modified object code on the User Product (for example, the work has
been installed in ROM).
The requirement to provide Installation Information does not include a
requirement to continue to provide support service, warranty, or updates
for a work that has been modified or installed by the recipient, or for
the User Product in which it has been modified or installed. Access to a
network may be denied when the modification itself materially and
adversely affects the operation of the network or violates the rules and
protocols for communication across the network.
Corresponding Source conveyed, and Installation Information provided,
in accord with this section must be in a format that is publicly
documented (and with an implementation available to the public in
source code form), and must require no special password or key for
unpacking, reading or copying.
7. Additional Terms.
"Additional permissions" are terms that supplement the terms of this
License by making exceptions from one or more of its conditions.
Additional permissions that are applicable to the entire Program shall
be treated as though they were included in this License, to the extent
that they are valid under applicable law. If additional permissions
apply only to part of the Program, that part may be used separately
under those permissions, but the entire Program remains governed by
this License without regard to the additional permissions.
When you convey a copy of a covered work, you may at your option
remove any additional permissions from that copy, or from any part of
it. (Additional permissions may be written to require their own
removal in certain cases when you modify the work.) You may place
additional permissions on material, added by you to a covered work,
for which you have or can give appropriate copyright permission.
Notwithstanding any other provision of this License, for material you
add to a covered work, you may (if authorized by the copyright holders of
that material) supplement the terms of this License with terms:
a) Disclaiming warranty or limiting liability differently from the
terms of sections 15 and 16 of this License; or
b) Requiring preservation of specified reasonable legal notices or
author attributions in that material or in the Appropriate Legal
Notices displayed by works containing it; or
c) Prohibiting misrepresentation of the origin of that material, or
requiring that modified versions of such material be marked in
reasonable ways as different from the original version; or
d) Limiting the use for publicity purposes of names of licensors or
authors of the material; or
e) Declining to grant rights under trademark law for use of some
trade names, trademarks, or service marks; or
f) Requiring indemnification of licensors and authors of that
material by anyone who conveys the material (or modified versions of
it) with contractual assumptions of liability to the recipient, for
any liability that these contractual assumptions directly impose on
those licensors and authors.
All other non-permissive additional terms are considered "further
restrictions" within the meaning of section 10. If the Program as you
received it, or any part of it, contains a notice stating that it is
governed by this License along with a term that is a further
restriction, you may remove that term. If a license document contains
a further restriction but permits relicensing or conveying under this
License, you may add to a covered work material governed by the terms
of that license document, provided that the further restriction does
not survive such relicensing or conveying.
If you add terms to a covered work in accord with this section, you
must place, in the relevant source files, a statement of the
additional terms that apply to those files, or a notice indicating
where to find the applicable terms.
Additional terms, permissive or non-permissive, may be stated in the
form of a separately written license, or stated as exceptions;
the above requirements apply either way.
8. Termination.
You may not propagate or modify a covered work except as expressly
provided under this License. Any attempt otherwise to propagate or
modify it is void, and will automatically terminate your rights under
this License (including any patent licenses granted under the third
paragraph of section 11).
However, if you cease all violation of this License, then your
license from a particular copyright holder is reinstated (a)
provisionally, unless and until the copyright holder explicitly and
finally terminates your license, and (b) permanently, if the copyright
holder fails to notify you of the violation by some reasonable means
prior to 60 days after the cessation.
Moreover, your license from a particular copyright holder is
reinstated permanently if the copyright holder notifies you of the
violation by some reasonable means, this is the first time you have
received notice of violation of this License (for any work) from that
copyright holder, and you cure the violation prior to 30 days after
your receipt of the notice.
Termination of your rights under this section does not terminate the
licenses of parties who have received copies or rights from you under
this License. If your rights have been terminated and not permanently
reinstated, you do not qualify to receive new licenses for the same
material under section 10.
9. Acceptance Not Required for Having Copies.
You are not required to accept this License in order to receive or
run a copy of the Program. Ancillary propagation of a covered work
occurring solely as a consequence of using peer-to-peer transmission
to receive a copy likewise does not require acceptance. However,
nothing other than this License grants you permission to propagate or
modify any covered work. These actions infringe copyright if you do
not accept this License. Therefore, by modifying or propagating a
covered work, you indicate your acceptance of this License to do so.
10. Automatic Licensing of Downstream Recipients.
Each time you convey a covered work, the recipient automatically
receives a license from the original licensors, to run, modify and
propagate that work, subject to this License. You are not responsible
for enforcing compliance by third parties with this License.
An "entity transaction" is a transaction transferring control of an
organization, or substantially all assets of one, or subdividing an
organization, or merging organizations. If propagation of a covered
work results from an entity transaction, each party to that
transaction who receives a copy of the work also receives whatever
licenses to the work the party's predecessor in interest had or could
give under the previous paragraph, plus a right to possession of the
Corresponding Source of the work from the predecessor in interest, if
the predecessor has it or can get it with reasonable efforts.
You may not impose any further restrictions on the exercise of the
rights granted or affirmed under this License. For example, you may
not impose a license fee, royalty, or other charge for exercise of
rights granted under this License, and you may not initiate litigation
(including a cross-claim or counterclaim in a lawsuit) alleging that
any patent claim is infringed by making, using, selling, offering for
sale, or importing the Program or any portion of it.
11. Patents.
A "contributor" is a copyright holder who authorizes use under this
License of the Program or a work on which the Program is based. The
work thus licensed is called the contributor's "contributor version".
A contributor's "essential patent claims" are all patent claims
owned or controlled by the contributor, whether already acquired or
hereafter acquired, that would be infringed by some manner, permitted
by this License, of making, using, or selling its contributor version,
but do not include claims that would be infringed only as a
consequence of further modification of the contributor version. For
purposes of this definition, "control" includes the right to grant
patent sublicenses in a manner consistent with the requirements of
this License.
Each contributor grants you a non-exclusive, worldwide, royalty-free
patent license under the contributor's essential patent claims, to
make, use, sell, offer for sale, import and otherwise run, modify and
propagate the contents of its contributor version.
In the following three paragraphs, a "patent license" is any express
agreement or commitment, however denominated, not to enforce a patent
(such as an express permission to practice a patent or covenant not to
sue for patent infringement). To "grant" such a patent license to a
party means to make such an agreement or commitment not to enforce a
patent against the party.
If you convey a covered work, knowingly relying on a patent license,
and the Corresponding Source of the work is not available for anyone
to copy, free of charge and under the terms of this License, through a
publicly available network server or other readily accessible means,
then you must either (1) cause the Corresponding Source to be so
available, or (2) arrange to deprive yourself of the benefit of the
patent license for this particular work, or (3) arrange, in a manner
consistent with the requirements of this License, to extend the patent
license to downstream recipients. "Knowingly relying" means you have
actual knowledge that, but for the patent license, your conveying the
covered work in a country, or your recipient's use of the covered work
in a country, would infringe one or more identifiable patents in that
country that you have reason to believe are valid.
If, pursuant to or in connection with a single transaction or
arrangement, you convey, or propagate by procuring conveyance of, a
covered work, and grant a patent license to some of the parties
receiving the covered work authorizing them to use, propagate, modify
or convey a specific copy of the covered work, then the patent license
you grant is automatically extended to all recipients of the covered
work and works based on it.
A patent license is "discriminatory" if it does not include within
the scope of its coverage, prohibits the exercise of, or is
conditioned on the non-exercise of one or more of the rights that are
specifically granted under this License. You may not convey a covered
work if you are a party to an arrangement with a third party that is
in the business of distributing software, under which you make payment
to the third party based on the extent of your activity of conveying
the work, and under which the third party grants, to any of the
parties who would receive the covered work from you, a discriminatory
patent license (a) in connection with copies of the covered work
conveyed by you (or copies made from those copies), or (b) primarily
for and in connection with specific products or compilations that
contain the covered work, unless you entered into that arrangement,
or that patent license was granted, prior to 28 March 2007.
Nothing in this License shall be construed as excluding or limiting
any implied license or other defenses to infringement that may
otherwise be available to you under applicable patent law.
12. No Surrender of Others' Freedom.
If conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot convey a
covered work so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you may
not convey it at all. For example, if you agree to terms that obligate you
to collect a royalty for further conveying from those to whom you convey
the Program, the only way you could satisfy both those terms and this
License would be to refrain entirely from conveying the Program.
13. Use with the GNU Affero General Public License.
Notwithstanding any other provision of this License, you have
permission to link or combine any covered work with a work licensed
under version 3 of the GNU Affero General Public License into a single
combined work, and to convey the resulting work. The terms of this
License will continue to apply to the part which is the covered work,
but the special requirements of the GNU Affero General Public License,
section 13, concerning interaction through a network will apply to the
combination as such.
14. Revised Versions of this License.
The Free Software Foundation may publish revised and/or new versions of
the GNU General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the
Program specifies that a certain numbered version of the GNU General
Public License "or any later version" applies to it, you have the
option of following the terms and conditions either of that numbered
version or of any later version published by the Free Software
Foundation. If the Program does not specify a version number of the
GNU General Public License, you may choose any version ever published
by the Free Software Foundation.
If the Program specifies that a proxy can decide which future
versions of the GNU General Public License can be used, that proxy's
public statement of acceptance of a version permanently authorizes you
to choose that version for the Program.
Later license versions may give you additional or different
permissions. However, no additional obligations are imposed on any
author or copyright holder as a result of your choosing to follow a
later version.
15. Disclaimer of Warranty.
THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
16. Limitation of Liability.
IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
SUCH DAMAGES.
17. Interpretation of Sections 15 and 16.
If the disclaimer of warranty and limitation of liability provided
above cannot be given local legal effect according to their terms,
reviewing courts shall apply local law that most closely approximates
an absolute waiver of all civil liability in connection with the
Program, unless a warranty or assumption of liability accompanies a
copy of the Program in return for a fee.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
state the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
&lt;one line to give the program's name and a brief idea of what it does.&gt;
Copyright (C) &lt;year&gt; &lt;name of author&gt;
This program is free software: you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation, either version 3 of the License, or
(at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License
along with this program. If not, see &lt;<a href="https://www.gnu.org/licenses/">https://www.gnu.org/licenses/</a>&gt;.
Also add information on how to contact you by electronic and paper mail.
If the program does terminal interaction, make it output a short
notice like this when it starts in an interactive mode:
&lt;program&gt; Copyright (C) &lt;year&gt; &lt;name of author&gt;
This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, your program's commands
might be different; for a GUI interface, you would use an "about box".
You should also get your employer (if you work as a programmer) or school,
if any, to sign a "copyright disclaimer" for the program, if necessary.
For more information on this, and how to apply and follow the GNU GPL, see
&lt;<a href="https://www.gnu.org/licenses/">https://www.gnu.org/licenses/</a>&gt;.
The GNU General Public License does not permit incorporating your program
into proprietary programs. If your program is a subroutine library, you
may consider it more useful to permit linking proprietary applications with
the library. If this is what you want to do, use the GNU Lesser General
Public License instead of this License. But first, please read

GNU GENERAL PUBLIC LICENSE
Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc.
51 Franklin Street - Fifth Floor, Boston, MA 02110-1301, USA.
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users. This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it. (Some other Free Software Foundation software is covered by
the GNU Library General Public License instead.) You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have. You must make sure that they, too, receive or can get the
source code. And you must show them these terms so they know their
rights.
We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.
Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary. To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and
modification follow.
<hr>
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License. The "Program", below,
refers to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language. (Hereinafter, translation is included without limitation in
the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.
You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any
part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.
c) If the modified program normally reads commands interactively
when run, you must cause it, when started running for such
interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a
notice that there is no warranty (or else, saying that you provide
a warranty) and that users may redistribute the program under
these conditions, and telling the user how to view a copy of this
License. (Exception: if the Program itself is interactive but
does not normally print such an announcement, your work based on
the Program is not required to print an announcement.)
<hr>
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.
In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of Sections
1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three
years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be
distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer
to distribute corresponding source code. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such
an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.
If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.
<hr>
4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.
5. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.
7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all. For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
<hr>
8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded. In such case, this License incorporates
the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation. If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.
10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission. For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.

<h3><a name=1>the transfer fails to finish</a></h3>
<p>If you get an error like one of these:
<pre>rsync: error writing 4 unbuffered bytes - exiting: Broken pipe
rsync error: error in rsync protocol data stream (code 12) at io.c(463)
</pre>
<p>or
<pre>rsync: connection unexpectedly closed (24 bytes read so far)
rsync error: error in rsync protocol data stream (code 12) at io.c(342)
</pre>
<p>please read the <a href="issues.html">issues and debugging page</a>
for details on how you can try to figure out what is going wrong.
<hr>
<h3><a name=2>rsync recopies the same files</a></h3>
<p>Some people occasionally report that rsync copies too many files when
they expect it to copy only a few. In most cases the explanation is
that you forgot to include the --times (-t) option in the original copy,
so rsync is forced to (efficiently) transfer every file that differs in
its modified time to discover what data (if any) has changed.
<p>Another common cause involves sending files to an Microsoft filesystem:
if the file's modified time is an odd value but the receiving filesystem
can only store even values, then rsync will re-transfer too many files.
You can avoid this by specifying the --modify-window=1 option.
<p>Yet another periodic case can happen when daylight-savings time
changes if your OS+filesystem saves file times in local time instead of
UTC. For a full explanation of this and some suggestions on how to
avoid them problem, see <a href="daylight-savings.html">this document</a>.
<p>Something else that can trip up rsync is a filesystem changeing the
filename behind the scenes. This can happen when a filesystem changes
an all-uppercase name into lowercase, or when it decomposes UTF-8 behind
your back.
<blockquote>
<p>An example of the latter can occur with HFS+ on Mac OS X: if you
copy a directory with a file that has a UTF-8 character sequence in it,
say a 2-byte umlaut-u (\0303\0274), the file will get that character
stored by the filesystem using 3 bytes (\0165\0314\0210), and rsync will
not know that these differing filenames are the same file (it will, in
fact, remove a prior copy of the file if --delete is enabled, and then
recreate it).
<p>You can avoid a charset problem by passing an appropriate --iconv
option to rsync that tells it what character-set the source files are,
and what character-set the destination files get stored in. For
instance, the above Mac OS X problem would be dealt with by using
--iconv=UTF-8,UTF8-MAC (UTF8-MAC is a pseudo-charset recognized by Mac
OS X iconv in which all characters are decomposed).
</blockquote>
<p>If you think that rsync is copying too many files, look at the
itemized output (-i) to see why rsync is doing the update (e.g. the 't'
flag indicates that the time differs, or all pluses indicates that rsync
thinks the file doesn't exist). You can also look at the stats produced
with -v and see if rsync is really sending all the data. See also the
--checksum (-c) option for one way to avoid the extra copying of files
that don't have synchronized modified times (but keep in mind that the
-c option eats lots of disk I/O, and can be rather slow).
<hr>
<h3><a name=3>is your shell clean</a></h3>
<p>The "is your shell clean" message and the "protocol mismatch" message
are usually caused by having some sort of program in your .cshrc, .profile,
.bashrc or equivalent file that writes a message every time you connect
using a remote-shell program (such as ssh or rsh). Data written in this
way corrupts the rsync data stream. rsync detects this at startup and
produces those error messages. However, if you are using rsync-daemon
syntax (host::path or rsync://) without using a remote-shell program (no
--rsh or -e option), there is not remote-shell program involved, and the
problem is probably caused by an error on the daemon side (so check the
daemon logs).
<p>A good way to test if your remote-shell connection is clean is to try
something like this (use ssh or rsh, as appropriate):
<blockquote><pre>ssh remotesystem /bin/true &gt; test.dat</pre></blockquote>
<p>That should create a file called test.dat with nothing in it. If
test.dat is not of zero length then your shell is not clean. Look at the
contents of test.dat to see what was sent. Look at all the startup files on
remotesystem to try and find the problem.
<hr>
<h3><a name=4>memory usage</a></h3>
<p>Rsync versions before 3.0.0 always build the entire list of files to be
transferred at the beginning and hold it in memory for the entire run. Rsync
needs about 100 bytes to store all the relevant information for one file,
so (for example) a run with 800,000 files would consume about 80M of
memory. -H and --delete increase the memory usage further.
<p>Version 3.0.0 slightly reduced the memory used per file by not storing fields
not needed for a particular file. It also introduced an incremental recursion
mode that builds the file list in chunks and holds each chunk in memory only as
long as it is needed. This mode dramatically reduces memory usage, but it
only works provided that both sides are 3.0.0 or newer and certain options that
rsync currently can't handle in this mode are not being used.
<hr>
<h3><a name=5>out of memory</a></h3>
<p>The usual reason for "out of memory" when running rsync is that you are
transferring a _very_ large number of files. The size of the files doesn't
matter, only the total number of files. If memory is a problem, first try to
use the incremental recursion mode: upgrade both sides to rsync 3.0.0 or
newer and avoid options that disable incremental recursion (e.g., use
<tt>--delete-delay</tt> instead of <tt>--delete-after</tt>). If this is not
possible, you can break the rsync run into smaller chunks operating on
individual subdirectories using <tt>--relative</tt> and/or exclude rules.
<hr>
<h3><a name=6>rsync through a firewall</a></h3>
<p>If you have a setup where there is no way to directly connect two
systems for an rsync transfer, there are several ways to get a firewall
system to act as an intermediary in the transfer. You'll find full details
on the <a href="firewall.html">firewall methods</a> page.
<hr>
<h3><a name=7>rsync and cron</a></h3>
<p>On some systems (notably SunOS4) cron supplies what looks like a socket
to rsync, so rsync thinks that stdin is a socket. This means that if you
start rsync with the --daemon switch from a cron job you end up rsync
thinking it has been started from inetd. The fix is simple&mdash;just
redirect stdin from /dev/null in your cron job.
<hr>
<h3><a name=8>rsync: Command not found</a></h3>
<p>This error is produced when the remote shell is unable to locate the rsync
binary in your path. There are 3 possible solutions:
<ol>
<li>install rsync in a "standard" location that is in your remote path.
<li>modify your .cshrc, .bashrc etc on the remote system to include the path
that rsync is in
<li>use the --rsync-path option to explicitly specify the path on the
remote system where rsync is installed
</ol>
<p>You may echo find the command:
<blockquote><pre>ssh host 'echo $PATH'</pre></blockquote>
<p>for determining what your remote path is.
<hr>
<h3><a name=9>spaces in filenames</a></h3>
<p>Can rsync copy files with spaces in them?
<p>Short answer: Yes, rsync can handle filenames with spaces.
<p>Long answer:
<p>Rsync handles spaces just like any other unix command line application.
Within the code spaces are treated just like any other character so a
filename with a space is no different from a filename with any other
character in it.
<p>The problem of spaces is in the argv processing done to interpret the
command line. As with any other unix application you have to escape spaces
in some way on the command line or they will be used to separate arguments.
<p>It is slightly trickier in rsync (and other remote-copy programs like
scp) because rsync sends a command line to the remote system to launch the
peer copy of rsync (this assumes that we're not talking about daemon mode,
which is not affected by this problem because no remote shell is involved
in the reception of the filenames). The command line is interpreted by the
remote shell and thus the spaces need to arrive on the remote system
escaped so that the shell doesn't split such filenames into multiple
arguments.
<p>For example:
<blockquote><pre>rsync -av host:'a long filename' /tmp/</pre></blockquote>
<p>This is usually a request for rsync to copy 3 files from the remote
system, "a", "long", and "filename" (the only exception to this is for a
system running a shell that does not word-split arguments in its commands,
and that is exceedingly rare). If you wanted to request a single file with
spaces, you need to get some kind of space-quoting characters to the remote
shell that is running the remote rsync command. The following commands
should all work:
<blockquote><pre>rsync -av host:'"a long filename"' /tmp/
rsync -av host:'a\ long\ filename' /tmp/
rsync -av host:a\\\ long\\\ filename /tmp/</pre></blockquote>
<p>You might also like to use a '?' in place of a space as long as there
are no other matching filenames than the one with spaces (since '?' matches
any character):
<blockquote><pre>rsync -av host:a?long?filename /tmp/</pre></blockquote>
<p>As long as you know that the remote filenames on the command line

<h3><a name=10>ignore "vanished files" warning</a></h3>
<p>Some folks would like to ignore the "vanished files" warning, which
manifests as an exit-code 24. The easiest way to do this is to create
a shell script wrapper. For instance, name this something like
"rsync-no24":
<blockquote><pre>#!/bin/sh
rsync "$@"
e=$?
if test $e = 24; then
exit 0
fi
exit $e</pre></blockquote>
<hr>
<h3><a name=11>read-only file system</a></h3>
<p>If you get "Read-only file system" as an error when sending to a rsync
daemon then you probably forgot to set "read only = no" for that module.
<hr>
<h3><a name=12>multiplexing overflow 101:7104843</a></h3>
<p>This mysterious error, or the similar "invalid message 101:7104843", can
happen if one of the rsync processes is killed for some reason and a message
beginning with the four characters "Kill" gets inserted into the protocol
stream as a result. To solve the problem, you'll need to figure out why rsync
is being killed.
<hr>
<h3><a name=13>inflate (token) returned -5</a></h3>
This error means that rsync failed to handle an expected error from the
compression code for a file that happened to be transferred with a block size
of 32816 bytes. You can avoid this issue for the affected file by transferring
it with a manually-set block size (e.g. --block-size=33000), or by upgrading
the receiving side to rsync 3.0.7.
