Subject: [PATCH] coredump: do not allow user to access coredumps with changed
uid/gid/capabilities
When the user starts a program which elevates its permissions via setuid,
setgid, or capabilities set on the file, it may access additional information
which would then be visible in the coredump. We shouldn't make the the coredump
visible to the user in such cases.
Reported-by: Matthias Gerstner <mgerstner@suse.de>
This reads the /proc/<pid>/auxv file and attaches it to the process metadata as
PROC_AUXV. Before the coredump is submitted, it is parsed and if either
at_secure was set (which the kernel will do for processes that are setuid,
setgid, or setcap), or if the effective uid/gid don't match uid/gid, the file
is not made accessible to the user. If we can't access this data, we assume the
file should not be made accessible either. In principle we could also access
the auxv data from a note in the core file, but that is much more complex and
it seems better to use the stand-alone file that is provided by the kernel.
Attaching auxv is both convient for this patch (because this way it's passed
between the stages along with other fields), but I think it makes sense to save
it in general.
We use the information early in the core file to figure out if the program was
32-bit or 64-bit and its endianness. This way we don't need heuristics to guess
whether the format of the auxv structure. This test might reject some cases on
fringe architecutes. But the impact would be limited: we just won't grant the
user permissions to view the coredump file. If people report that we're missing
some cases, we can always enhance this to support more architectures.
I tested auxv parsing on amd64, 32-bit program on amd64, arm64, arm32, and
ppc64el, but not the whole coredump handling.

Subject: [PATCH] coredump: avoid deadlock when passing processed backtrace
data
We would deadlock when passing the data back from the forked-off process that
was doing backtrace generation back to the coredump parent. This is because we
fork the child and wait for it to exit. The child tries to write too much data
to the output pipe, and and after the first 64k blocks on the parent because
the pipe is full. The bug surfaced in Fedora because of a combination of four
factors:
- 87707784c70dc9894ec613df0a6e75e732a362a3 was backported to v251.5, which
allowed coredump processing to be successful.
- 1a0281a3ebf4f8c16d40aa9e63103f16cd23bb2a was NOT backported, so the output
was very verbose.
- Fedora has the ELF package metadata available, so a lot of output can be
generated. Most other distros just don't have the information.
- gnome-calendar crashes and has a bazillion modules and 69596 bytes of output
are generated for it.
Fixes https://bugzilla.redhat.com/show_bug.cgi?id=2135778.
The code is changed to try to write data opportunistically. If we get partial
information, that is still logged. In is generally better to log partial
backtrace information than nothing at all.

Subject: [PATCH] test: disable flaky subtests that require udevadm wait/lock
Certain TEST-64-UDEV-STORAGE tests require `udevadm wait` and `udevadm
lock` verbs to work reliably. Since we don't plan to backport the verbs
to RHEL 9.1 and older, let's skip the tests to make CIs a bit more
reliable when dealing with z-streams.
Necessary only on RHEL 9.1 and 9.0.
