Package: libc6 Version: 2.36-9+deb12u13 Severity: important File: /lib/x86_64-linux-gnu/libc.so.6 Tags: upstream
Dear Maintainer, glibc as part of Debian Bookworm is affected by the following upstream bug: https://sourceware.org/bugzilla/show_bug.cgi?id=25847 To avoid confusion I'm not repeating the details here. The result is a broken synchronization primitive. condition variables might miss a wakeup event. The issue is fixed in glibc 2.41 and newer. There is a patch series targeting the 2.36 branch available at https://inbox.sourceware.org/libc-stable/[email protected]/ Upstream did not apply the series yet. There have been concerns about breaking existing software - which should not affect Debian. More details in the referenced upstream bug. The patches can be applied as is to the Debian bookworm glibc based on 2.36. I'm running that for some time now, the reproducer is no longer working inside a Debian 12 podman container. Is there a chance that we get this bug fixed in Debian bookworm? -- System Information: Debian Release: 12.13 APT prefers oldstable-updates APT policy: (500, 'oldstable-updates'), (500, 'oldstable-security'), (500, 'oldstable') Architecture: amd64 (x86_64) Kernel: Linux 6.19.9-200.fc43.x86_64 (SMP w/8 CPU threads; PREEMPT) Locale: LANG=C, LC_CTYPE=C.UTF-8 (charmap=UTF-8), LANGUAGE not set Shell: /bin/sh linked to /usr/bin/dash Init: unable to detect Versions of packages libc6:amd64 depends on: ii libgcc-s1 12.2.0-14+deb12u1 Versions of packages libc6:amd64 recommends: ii libidn2-0 2.3.3-1+b1 Versions of packages libc6:amd64 suggests: ii debconf [debconf-2.0] 1.5.82 pn glibc-doc <none> pn libc-l10n <none> pn libnss-nis <none> pn libnss-nisplus <none> pn locales <none> -- debconf information excluded Best regards, Florian
