Subject: [PATCH] execute: Pass AT_FDCWD instead of -1
|
||||||
|
|
||||||
|
Let's enforce that callers pass AT_FDCWD as read_dfd to load_credential()
|
||||||
|
to avoid an assert() in read_full_file_full() if read_dfd is -1.
|
||||||
|
|
||||||
|
(cherry picked from commit 661e4251a5b157d1aee1df98fbd2f0c95285ebba)
|
||||||
|
|
||||||
|
Resolves: RHEL-32259

Subject: [PATCH] coredump: generate stacktraces also for processes running in

Note that entering container namespace has to be explicitly enabled by

setting SYSTEMD_COREDUMP_ALLOW_NAMESPACE_CHANGE environment variable.

Subject: [PATCH] test: don't expand the subshell expression prematurely
|
||||||
|
|
||||||
|
We need to expand the subshell expression during the `bash -c`
|
||||||
|
invocation, not before, to take the desired effect, as now it expands to:
|
||||||
|
|
||||||
|
timeout 30 bash -c 'while [[ 0 -eq 0 ]]; do sleep 1; done'
|
||||||
|
|
||||||
|
instead of the expected:
|
||||||
|
|
||||||
|
timeout 30 bash -c 'while [[ $(coredumpctl list -q --no-legend 770 | wc -l) -eq 0 ]]; do sleep 1; done'
|
||||||
|
|
||||||
|
Follow-up to aadbd81f7f.

Subject: [PATCH] coredump filter: fix stack overflow with =all
|
||||||
|
|
||||||
|
We translate 'all' to UNIT64_MAX, which has a lot more 'f's. Use the
|
||||||
|
helper macro, since a decimal uint64_t will always be >> than a hex
|
||||||
|
representation.

||||||
|
|
||||||

Subject: [PATCH] coredump filter: add mask for 'all' using UINT32_MAX, not

|
UINT64_MAX
|
||||||
|
|
||||||
|
The kernel returns ERANGE when UINT64_MAX is passed. Create a mask
|
||||||
|
and use UINT32_max, which is accepted, so that future bits will also
|
||||||
|
be set.

On faster machines we might be too fast and kill the fake binary during

fork() which then makes kernel report a "wrong" binary in the coredump,

Subject: [PATCH] test: check coredump handling in containers & namespaces
|
||||||
|
|
||||||
|
This is partially based on upstream's 097e28736a, which tests coredump
|
||||||
|
forwarding (that we don't have in RHEL 9). It also provides basic
|
||||||
|
coverage for RHEL-29430 (generating stack traces for processes in
|
||||||
|
containers without coredump fowarding).

Subject: [PATCH] kernel-install: fix uki-copy deinstall
|
||||||
|
|
||||||
|
For "kernel-install remove ..." only the kernel version is passed, not
|
||||||
|
the kernel image. So auto-detecting KERNEL_INSTALL_IMAGE_TYPE and
|
||||||
|
setting KERNEL_INSTALL_LAYOUT does not work for uninstall.
|
||||||
|
|
||||||
|
The 90-uki-copy.install plugin must consider this and *not* exit early
|
||||||
|
for the "remove" command, otherwise $BOOT_ROOT will be filled with stale
|
||||||
|
kernel images.

Subject: [PATCH] cryptsetup: do not assert when unsealing token without salt
|
||||||
|
|
||||||
|
Salt was added in v253. We are not checking whether it was actually found
|
||||||
|
(non-zero size), so when an old tpm+pin enrollment is opened things go boom.
|
||||||
|
For good measure, check both the buffer and the size in both places.
|
||||||
|
|
||||||
|
Assertion 'saltlen > 0' failed at src/shared/tpm2-util.c:2490, function tpm2_util_pbkdf2_hmac_sha256(). Aborting.
