When a package defines $(PKG)_FLAT_STACKSIZE, ELF2FLT_FLAGS contains
-Wl,-elf2flt="-r -s<stack-size>". The embedded quotes are needed to
keep both elf2flt options in single linker argument.
However, many package Makefiles wrap $(TARGET_CFLAGS) in double quotes,
for example:
CFLAGS="$(TARGET_CFLAGS)"
After expansion, the embedded quote terminates the outer CFLAGS quote.
As a result, the shell interprets "-s<stack-size> ..." as a command
instead of passing it to the compiler.
Pass -r and -s<stack-size> in separate -Wl arguments instead. This
avoids embedded quotes; GCC forwards both -elf2flt options to
ld-elf2flt, which collects them before invoking elf2flt.
This got broken by commit
04d7ea4720 ("package: Makefile.in: fix
elf2flt invocation options"), which by adding -r as an elf2flt
argument, did not correctly handle -s$($(PKG)_FLAT_STACKSIZE).

wine.mk passes --with-wayland whenever BR2_PACKAGE_WAYLAND is enabled,
but nothing guarantees the rest of what wine's Wayland test needs is in
the configuration. That test is:
WINE_NOTICE_WITH(wayland, [test -z "$WAYLAND_CLIENT_LIBS" \
-o -z "$WAYLAND_SCANNER" -o -z "$XKBCOMMON_LIBS" \
-o -z "$XKBREGISTRY_LIBS" -o "$ac_cv_header_linux_input_h" = "no"], ...)
and because --with-wayland is passed explicitly, WINE_NOTICE_WITH turns
into AC_MSG_ERROR rather than a notice.
So wine needs libxkbcommon, and it needs the libxkbregistry part of it,
which is only built when libxml2 is available. Select both when Wayland
support is enabled, and add libxkbcommon to the build dependencies.
Note that libxml2 is not a direct dependency of wine, it only has to be
in the configuration so that libxkbcommon builds libxkbregistry; the
build ordering is handled by libxkbcommon's own dependency on libxml2.

libxkbregistry is the keyboard layout catalogue half of the library. It
parses the XML layout registry and so needs libxml2, which is presumably
why it was disabled unconditionally rather than wired to a dependency.
wine needs it. Its configure.ac requires XKBREGISTRY_LIBS alongside
wayland-client, wayland-scanner, xkbcommon and linux/input.h before it
will build the Wayland driver, and wine.mk passes --with-wayland for any
build with BR2_PACKAGE_WAYLAND - which turns that notice into a hard
error:
checking for wayland-client.h... yes
checking for wl_display_connect in -lwayland-client... yes
checking for wayland-scanner... .../host/bin/wayland-scanner
checking for xkb_context_new in -lxkbcommon... yes
checking for wayland-egl.h... yes
checking for wl_egl_window_create in -lwayland-egl... yes
configure: error: Wayland development files not found, the Wayland
driver won't be supported.
This is an error since --with-wayland was requested.
Every other term of that test passes; only XKBREGISTRY_LIBS is empty, so
wine and wayland together could not be built on any architecture.
Gated on BR2_PACKAGE_LIBXML2 rather than turned on outright, because
meson.build takes dependency('libxml-2.0') unconditionally once
enable-xkbregistry is set, so a target without libxml2 would fail to
configure.
Regarding since when this is broken, three pieces had to come together:
- libxkbcommon has passed -Denable-xkbregistry=false since commit
1791bc30a5 ("package/libxkbcommon: bump version to 1.0.1", Sep 2020),
i.e. Buildroot 2020.11. libxkbregistry has therefore never been built
in Buildroot.
- wine's configure gained the XKBREGISTRY_LIBS term in its Wayland
test in wine 9.0, with upstream commit d64ea8e4a6c9
("winewayland.drv: Enumerate Xkb layouts and create matching HKL.",
Nov 2023).
- wine.mk started passing --with-wayland in commit 7cb49e7712
("package/wine: bump to version 9.19", Oct 2024), which is what turns
the missing XKBREGISTRY_LIBS from a notice into a hard error.
The breakage therefore dates from Buildroot 2024.11, and every branch
since is affected, including the LTS one: 2025.02.x carries wine 10.0,
whose configure has the XKBREGISTRY_LIBS check, together with
libxkbcommon 1.9.2 built with -Denable-xkbregistry=false, and its wine.mk
passes --with-wayland. 2025.05.x and 2025.08.x are in the same state.
A backport to 2025.02.x is thus needed.

Fixes the following security issues:
- x/mod/sumdb/tlog: fix transparency log tile verification bypass
A malicious GOPROXY was previously capable of forging up to two sumdb
tiles that allow for a requested module to bypass the GOSUMDB check and
persist attacker-controlled module content to a local Go module cache.
This attack allows for a malicious GOPROXY to serve malicious module
content that cannot be detected by evaluating the transparency log.
All tiles are now correctly verified against their parents.

- net/http: apply ReadHeaderTimeout when doing unencrypted HTTP/2 check
When a server is configured to support unencrypted HTTP/2, it reads a few
bytes from each new connection to see if they contain the HTTP/2 client
preface. Previously, this was being done with no timeout applied.
ReadHeaderTimeout is now applied for this.
This is CVE-2026-56853 and Go issue https://go.dev/issue/80205.
- net/url: avoid quadratic complexity in resolvePath
Previously, resolving relative paths containing parent directory (..)
segments performed string conversions and buffer rewrites on each step,
resulting in quadratic time complexity and high memory allocation
overhead.
Now, path resolution operates on a byte buffer using index-based
backtracking for .. segments, eliminating the quadratic time complexity
and significantly reducing memory allocations.

- x/net/idna: failure to reject ASCII-only Punycode-encoded labels
The ToASCII and ToUnicode functions incorrectly accepted Punycode-encoded
labels that decode to an ASCII-only label. For example,
ToUnicode("xn--example-.com") incorrectly returned the name "example.com"
rather than an error.
The idna package implements the processing algorithm from UTS 46. Older
versions of UTS 46 included a specification bug which permitted multiple
ASCII labels to decode to the same Unicode label. UTS 46 revision 33
fixed the specification bug. The idna package now implements the updated
specification.
This behavior can lead to privilege escalation in programs using the idna
package. For example, a program which performs privilege checks on the
ASCII hostname may reject "example.com" but permit "xn--example-.com".
If that program subsequently converts the ASCII hostname to Unicode, it
will inadvertently permits access to the Unicode name "example.com".

Bugfix release with large number of (security) fixes.
HAProxy 2.6.32 was released on 2026/07/29. It added 33 new commits
after version 2.6.31.
As for the 2.8.27, the announce is an expurgated copy-paste of the 3.4.3
announce:
* stats: Two issues about the stats page, reported by Red Hat/AISLE
Research, were fixed.
Proxies updated through the stats page while in "stats admin" mode were
not subject to the "stats scope" filtering, meaning a scope meant to
restrict which proxies are visible/actionable could be silently bypassed
on POST requests.
Separately, POST requests to the stats interface did not validate that the
Origin (or Referer) header matched the Host, which is now checked to
mitigate CSRF attacks.
* ssl-gencert: A memory leak on every certificate generation was fixed.
Two temporary buffers were not freed after generating a certificate on the
fly, leaking memory each time a new SNI triggered certificate
generation. This issue was reported by Red Hat/AISLE Research.
* sample/protobuf: buffer overflows after pointer-shift converters, reported
by Red Hat/AISLE Research and Charles Vosburgh, were fixed.
Several converters (protobuf/ungrpc field extraction, ltrim())
move the sample's data pointer forward on success but did not shrink the
sample's recorded buffer capacity accordingly. A converter chained
afterwards that relies on that capacity (e.g. padding via memset()) could
then write past the end of the buffer, leading to heap corruption or a
worker crash. All the affected converters now adjust the capacity
together with the pointer.
* protobuf: A nested-path validation bypass reported by Red Hat/AISLE
Research was fixed.
The protobuf field lookup used for the protobuf()/ungrpc() converters did
not strictly enforce hierarchical boundaries, so a flat sibling field
could incorrectly satisfy a nested-path lookup (e.g. matching a root-level
field as if it were nested under a parent). The lookup was rewritten as a
strict, non-recursive path walker that correctly bounds each nesting
level.
Separately, a crash because of deprecated protobuf group wire types was
fixed. These wire types are now explicitly rejected.
* http-fetch: Two crashes reachable from health-check configurations were
fixed.
"res.body"/"res.hdr"/... and similar response fetches assumed the
health-check receive buffer always held an HTX message, which is only true
for actual HTTP checks; on a plain TCP check, a hostile/misbehaving server
could craft the first bytes of its reply to be misinterpreted as HTX
internal fields, causing a wild read and worker crash (or leaking
arbitrary process memory).
Separately, "capture.req.hdr"/"capture.res.hdr" only validated the upper
bound of their index argument, so a negative capture id was accepted at
boot and dereferenced an out-of-bounds array entry at runtime, crashing
the worker on the very first request.
* slz: Several issues were fixed in the SLZ library.
A stream alternating many literals in the 144-255 range with cheap
back-references could keep inflating indefinitely instead of falling
back to a stored block, exceeding the library's documented worst-case
output size by several percent. A new accounting mechanism now bounds
this overhead. Practical impact on haproxy requires tune.bufsize above
~43 kB with the default reserve.
Five small correctness fixes inherited from upstream libslz were also
backported: Avoid reading up to a few bytes past the end of very short
inputs on architectures without fast unaligned access; stop appending an
extra, misplaced block to an already-finished deflate/gzip/zlib stream
(which could corrupt the trailing checksum in ~2% of fuzzed streams); fix
the Adler32 checksum accumulator sign handling on 32-bit systems
(affecting the zlib format only); avoid an undefined-behaviour signed left
shift when assembling input words byte by byte; and use the exact bit cost
when deciding whether to emit the last literals of a block as a stored
block, avoiding compressed output slightly larger than the documented
worst case.
* peers: A heap overflow when replicating large stick-table dictionary
entries was fixed.
peer_prepare_updatemsg() never verified that a stick-table entry's
dictionary value (e.g. server_key, up to ~16 kB) actually fit in the
update message being built. Since the peers protocol is plain-text and
unauthenticated, a rogue or compromised peer could plant an oversized
entry that overflows the 16 kB trash buffer as soon as the victim
replicates ("teaches") it, confirmed as a heap-buffer-overflow write. The
function now checks the available room before encoding and fails cleanly
if it doesn't fit. This was reported and fixes by Matt Suiche from Tolmo
Inc.
And, as usual, the bunch of minor fixes here and there, mainly raised during
AI-assisted code reviews. Most were never noticed:
* HTX API: Some bugs about how the HTX API was used were fixed here and
there.
* http-act: Double-frees and a couple of state bugs on parsing errors were
fixed.
* http-fetch/http-ana/http-htx: Few out-of-bounds reads were fixed.
* http-conv: The last input character could be lost when calling url-dec
converter, when the input buffer was full. This was fixed by failing the
converter in that case.
* mux-h1: An extra 200ms delay was observed on some H2-to-H1 messages
because the end of the message was not always properly detected. This
case is now properly handled.
* sample: An edge case in be2hex() was fixed.

The previous configuration placed both logs and PID file in /var/logs,
which is not writable with a read-only rootfs (e.g. squashfs), as well
as non-standard. Starting HTTPD during boot failed with:
(30)Read-only file system: AH00091: httpd: could not open error log file /var/logs/error_log.
AH00015: Unable to open logs
An additional issue was that the Buildroot-default --prefix=/usr
override meant various Apache-internal directories (e.g. htdocs) were
placed directly in /usr. Note that the upstream default prefix is
/usr/local/apache2, not /usr/local.
Using the "Debian" layout provides a standard-compatible layout with
logs in /var/log/apache2 and PID file in /var/run/apache2 (both in
tmpfs with the default Buildroot fstab). Both directories need to
exist when the server starts, so handle that in the init script.

==========================
This release contains a number of security fixes and small bugfixes.
Security
========
* ssh-agent(1): fix an interaction between agent locking and the
session-bind@openssh.com extension that is used to identify
forwarded agents. These binding requests were refused when the
agent was locked, with the result that operations that were
intended to be limited to local use only could be performed
remotely, including the ability to add PKCS#11 tokens and make
use of keys that had destination restrictions applied.
Reported by sn0x-sharma
* ssh(1): avoid potential realloc use-after-free in the client if a
remote forwarding is added via the local session multiplexing
socket while a remote forwarding open request is pending with the
server. Report and fix from Brian Mingus of Cognatory
* sshd(8): make the authorized_keys "restrict" keyword apply
correctly to tunnel forwarding too (which is administratively
disabled by default). Reported by Erichen, Institute of Computing
Technology, Chinese Academy of Sciences
