Bug#1071920: bookworm-pu: package libseccomp/2.5.4-1+deb12u1
Package: release.debian.org
User: release.debian.org@packages.debian.org
Usertags: pu
Tags: bookworm
Severity: normal
[ Reason ]
libseccomp 2.5.4 only knows about syscall up to Linux 6.4.
The proposed changes add the syscalls up to Linux 6.7.
[ Impact ]
Syscalls for Linux 6.5 to 6.7 can't be allowed.
Software built with support for newer kernels (often the case in containers)
expect newer syscalls to work or return ENOSYS.
If that syscall is not supported by libseccomp and a default filter action of
returning EPERM is used, such software will break.
Therefore you often need to be able to allow a syscall even when the running
kernel doesn't support it.
[ Tests ]
* autopkgtest passes on amd64
* Verified adding a filter for the fchmodat2() syscall works (new in 6.6)
* Verified that systemd and Docker run
[ Risks ]
The changes only extend the syscall csv table and add new syscall defines.
[ Checklist ]
[x] *all* changes are documented in the d/changelog
[x] I reviewed all changes and I approve them
[x] attach debdiff against the package in (old)stable
[x] the issue is verified as fixed in unstable
[ Changes ]
Cherry-pick upstream commit to support new syscalls.
