Release/2.44

1. Current status

glibc-2.44 has been released on 2026-07-25.

Preparation schedule:

• 20 June 2026: Soft freeze
  • No *starting* of new features anymore
  • Decisions on what goes still in and what goes not
  • Review and addition of patches
• 4 July 2026: Freeze
  • Machine testing
  • Bug fixes without large impact
  • No ABI changes without RM discussion
  • High risk bug fixes should be discussed on the list.
• 18 July 2026: Hard freeze
  • Only critically important or technically straightforward bug fixes
  • Release can happen when things are ready
• 1 Aug 2026 (or ideally a bit earlier): Release

The release branch of glibc-2.44 is/will be maintained by Andreas K. Hüttel <dilfridge@gentoo.org>.

The ref structure of this branch is:

• release/2.44/master: Rolling release main branch

The general policies for release branches apply to this branch. Do you think a certain bugfix should be included in this branch?

1. Is the fix committed in master? It has to be, unless it's not applicable to master (e.g. code has been rewritten meantime).
2. Do you have commit permissions? If so, go ahead if you think it's reasonably safe. break;
3. Can you handle Git yourself? Then you can clone the glibc repository, cherry-pick the appropriate fixes, push your branch out and send a pull request at libc-alpha. break;
4. If there is no appropriate bug report, send a request for the fix to be included to libc-alpha.

The release/2.44/master branch is intended as a rolling release for all distributions to use and contribute fixes to from development master.

2. Changes relevant for packagers and distributions

2.1. spawn.h makes Gnulib produce posix_spawn_file_actions_addchdir_np() infinitely recursing into itself

Still under discussion at https://sourceware.org/pipermail/libc-alpha/2026-July/179161.html. A temporary workaround is passing ac_cv_func_posix_spawn_file_actions_addchdir=yes to configure.

3. Planning

What things do we want to accomplish this release?

3.1. Release blockers?

3.2. Desirable this release?

3.3. Already fixed / merged from above

• elf: parse /proc/self/maps as the last resort to find the gap for tst-link-map-contiguous-ldso

• malloc: Don't call __get_thp_mode/__get_thp_size twice

• manual: Document indirect functions (IFUNC)

• ppc64le: Restore optimized memchr for power10 [BZ #34300]

• system-wide tunables

• Improve make and make check parallelism

• Revert "malloc: aarch64: Add ifuncs for malloc functions"

• s390: Prevent hoisting the thread-pointer read in THREAD_SET_STACK_GUARD (BZ 34297)

• tunables overridability

• Fixes for the system-wide tunables support (builds on "tunables overridability")

• benchtests: Build benchmarks in parallel

• sparc: Fix static (non-PIE) executables when PIE is enabled by default

• Use correct type for glibc.malloc.perturb in tst-tunconf1.c

• posix: Fix wordexp WRDE_APPEND to preserve state on non-NOSPACE errors (BZ 34090, CVE-2026-6368)

• Add RWF_NOSIGNAL from Linux 6.18 to bits/uio-ext.h

• math: Fix unsupported check in test-narrowing-trap

3.4. Deferred to next release

• elf: Make string tunables startup-only

• TCB layout changes
  • Before the last release two changes were reverted because of problems with the Chromium sandbox:
    • a257f201dd Revert "x86_64: Remove unused padding from tcbhead_t"
    • c4ed6a380e Revert "nptl: More useful padding in struct pthread"
• malloc ifuncs: reverted for 2.44, reapply immediately afterwards

• linux: Do not spawn a new thread for SIGEV_THREAD (BZ 30558, 27895, 29705, 32833)

  • Carlos: Would like this committed when the development branch opens again and get some testing from the distributions.
    • Once we know the fixes work reliably then we can backport.

• elf: Remove dead l_need_tls_init static-TLS init path

• linux: Inline syscall cancellation to keep wrapper frames observable

• tests: Align THP tests to the 32MB huge-page size

• io: fix ftw ABI on MIPS n64

4. Build and test results

Describe build and test issues for each architecture, or confirm a clean build with no testsuite failures. The list below is not a complete list of ABI variants; testing should try to cover the different ABI variants as far as possible, and possibly also variations in configure and build options. Template:

4.0.1. some identifier of the machine

• compiler: gcc -v

• binutils: ld -v

• kernel: uname -a

• git commit tested
• build type (manual, with package manager, ci, ...)
• configure command line and/or relevant variables

• tester: Your Name

FAIL test-regex-el (exit status: 1)

test-regex-el was added on 7/May/2026 (gnulib commit f762dbf461c65c2740f5a39463c6fc6a06af61b1) and tests for glibc bug 20381, initially filed 2016. So this is not a regression in glibc.

The bug is fixed in the gnulib version of the code and will be fixed in glibc once that is synced over(?).
