Subject: [PATCH] journald: add API to move logging from /var to /run again
We now have this nice little Varlink API, let's beef it up a bit.
[dtardon: This diverges from the upstream commit in two ways: One is
that the new action is bound to a signal, as varlink is not available.
The other is that this introduces a new "flag" file
/run/systemd/journal/relinquished, which is essentially the opposite of
/run/systemd/journal/flushed (hence at most one of them may exist at any
time).]
(cherry picked from commit b4e26d1d8e582d78e67ed766177f10e8e194404c)

Subject: [PATCH] journalctl: add new --relinquish and --smart-relinquish
options
The latter is identical to the former, but becomes a NOP if
/var/log/journal is on the same mount as /, and thus during shutdown
unmounting /var is not necessary and hence we can keep logging until the
very end.
[dtardon: The only divergence from the upstream commit is the impl. of
relinquish_var().]

Subject: [PATCH] pstore: Tool to archive contents of pstore
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This patch introduces the systemd pstore service which will archive the
contents of the Linux persistent storage filesystem, pstore, to other storage,
thus preserving the existing information contained in the pstore, and clearing
pstore storage for future error events.
Linux provides a persistent storage file system, pstore[1], that can store
error records when the kernel dies (or reboots or powers-off). These records in
turn can be referenced to debug kernel problems (currently the kernel stuffs
the tail of the dmesg, which also contains a stack backtrace, into pstore).
The pstore file system supports a variety of backends that map onto persistent
storage, such as the ACPI ERST[2, Section 18.5 Error Serialization] and UEFI
variables[3 Appendix N Common Platform Error Record]. The pstore backends
typically offer a relatively small amount of persistent storage, e.g. 64KiB,
which can quickly fill up and thus prevent subsequent kernel crashes from
recording errors. Thus there is a need to monitor and extract the pstore
contents so that future kernel problems can also record information in the
pstore.
The pstore service is independent of the kdump service. In cloud environments
specifically, host and guest filesystems are on remote filesystems (eg. iSCSI
or NFS), thus kdump relies [implicitly and/or explicitly] upon proper operation
of networking software *and* hardware *and* infrastructure. Thus it may not be
possible to capture a kernel coredump to a file since writes over the network
may not be possible.
The pstore backend, on the other hand, is completely local and provides a path
to store error records which will survive a reboot and aid in post-mortem
debugging.
Usage Notes:
This tool moves files from /sys/fs/pstore into /var/lib/systemd/pstore.
To enable kernel recording of error records into pstore, one must either pass
crash_kexec_post_notifiers[4] to the kernel command line or enable via 'echo Y
> /sys/module/kernel/parameters/crash_kexec_post_notifiers'. This option
invokes the recording of errors into pstore *before* an attempt to kexec/kdump
on a kernel crash.
Optionally, to record reboots and shutdowns in the pstore, one can either pass
the printk.always_kmsg_dump[4] to the kernel command line or enable via 'echo Y >
/sys/module/printk/parameters/always_kmsg_dump'. This option enables code on the
shutdown path to record information via pstore.
This pstore service is a oneshot service. When run, the service invokes
systemd-pstore which is a tool that performs the following:
- reads the pstore.conf configuration file
- collects the lists of files in the pstore (eg. /sys/fs/pstore)
- for certain file types (eg. dmesg) a handler is invoked
- for all other files, the file is moved from pstore
- In the case of dmesg handler, final processing occurs as such:
- files processed in reverse lexigraphical order to faciliate
reconstruction of original dmesg
- the filename is examined to determine which dmesg it is a part
- the file is appended to the reconstructed dmesg
For example, the following pstore contents:
root@vm356:~# ls -al /sys/fs/pstore
total 0
drwxr-x--- 2 root root 0 May 9 09:50 .
drwxr-xr-x 7 root root 0 May 9 09:50 ..

Configuration file:
The pstore.conf configuration file has four settings, described below.
- Storage : one of "none", "external", or "journal". With "none", this
tool leaves the contents of pstore untouched. With "external", the
contents of the pstore are moved into the /var/lib/systemd/pstore,
as well as logged into the journal. With "journal", the contents of
the pstore are recorded only in the systemd journal. The default is
"external".
- Unlink : is a boolean. When "true", the default, then files in the
pstore are removed once processed. When "false", processing of the
pstore occurs normally, but the pstore files remain.

+ <title>Description</title>
+ <para><filename>systemd-pstore.service</filename> is a system service that archives the
+ contents of the Linux persistent storage filesystem, pstore, to other storage,
+ thus preserving the existing information contained in the pstore, and clearing
+ pstore storage for future error events.</para>
+
+ <para>Linux provides a persistent storage file system, pstore, that can store
+ error records when the kernel dies (or reboots or powers-off). These records in
+ turn can be referenced to debug kernel problems (currently the kernel stuffs
+ the tail of the dmesg, which also contains a stack backtrace, into pstore).</para>
+
+ <para>The pstore file system supports a variety of backends that map onto persistent
+ storage, such as the ACPI ERST and UEFI variables. The pstore backends
+ typically offer a relatively small amount of persistent storage, e.g. 64KiB,
+ which can quickly fill up and thus prevent subsequent kernel crashes from
+ recording errors. Thus there is a need to monitor and extract the pstore
+ contents so that future kernel problems can also record information in the
+ pstore.</para>
+
+ <para>The pstore service is independent of the kdump service. In cloud environments
+ specifically, host and guest filesystems are on remote filesystems (eg. iSCSI
+ or NFS), thus kdump relies [implicitly and/or explicitly] upon proper operation
+ of networking software *and* hardware *and* infrastructure. Thus it may not be
+ possible to capture a kernel coredump to a file since writes over the network
+ may not be possible.</para>
+
+ <para>The pstore backend, on the other hand, is completely local and provides a path
+ to store error records which will survive a reboot and aid in post-mortem
+ debugging.</para>
+
+ <para>The <command>systemd-pstore</command> executable does the actual work. Upon starting,
+ the <filename>pstore.conf</filename> is read to obtain options, then the /sys/fs/pstore
+ directory contents are processed according to the options. Pstore files are written to the
+ journal, and optionally saved into /var/lib/systemd/pstore.</para>
+ </refsect1>
+
+ <refsect1>
+ <title>Configuration</title>
+
+ <para>The behavior of <command>systemd-pstore</command> is configured through the configuration file
+ <filename>/etc/systemd/pstore.conf</filename> and corresponding snippets
+ <filename>/etc/systemd/pstore.conf.d/*.conf</filename>, see

Subject: [PATCH] pstore: allow specifying src and dst dirs are arguments
This makes it much easier to debug the program as a normal user, since we
don't need to set up fake input under /sys/fs/pstore/.
Also, let's make the debug output a bit nicer.

Let's use a more standard pattern: allocate memory using greedy_realloc, and
instead of freeing it when we wrote out a chunk, let's just move the cursor
back to the beginning and reuse the memory we allocated previously.
If we fail to allocate the memory for dmesg contents, don't write the dmesg
entry, but let's still process the files to move them out of pstore.

Subject: [PATCH] pstore: fixes for dmesg.txt reconstruction
This patch fixes problems with the re-assembly of the dmesg
from the records stored in pstore.
The current code simply ignores the last 6 characters of the
file name to form a base record id, which then groups any
pstore files with this base id into the reconstructed dmesg.txt.
This approach fails when the following oops generated the
following in pstore:

The above is a interleaved mess of three dmesg dumps.
This patch fixes the above problems, and simplifies the dmesg
reconstruction process. The code now distinguishes between
records on EFI vs ERST, which have differently formatted
record identifiers. Using knowledge of the format of the
record ids allows vastly improved reconstruction process.
With this change in place, the above pstore records now
result in the following:

new dmesg.txt, as needed.

Effectively this doesn't mean much, either way our unit is part of the

Subject: [PATCH] units: drop dependency on systemd-remount-fs.service from
systemd-pstore.service
This dependency is now generated automatically given we use
StateDirectory=. Moreover the combination of Wants= and After= was too
strong anway, as whether remount-fs is pulled in or not should not be up
to systemd-pstore.service, and in fact is part of the initial
transaction anyway.
[dtardon: This only removes Wants=, not After=, because I haven't
backported the auto-generation code the description talks about. The
code is simple, but it's just an optimisation allowing for slightly
shorter unit files, hence I don't think we really need it.]

Subject: [PATCH] pstore: Run after modules are loaded
The systemd-pstore service takes pstore files on boot and transfers them
to disk. It only does it once on boot and only if it finds any. The typical
location of the pstore on modern systems is the UEFI variable store.
Most distributions ship with CONFIG_EFI_VARS_PSTORE=m. That means, the
UEFI variable store is only available on boot after the respective module
is loaded.
In most situations, the pstore service gets loaded before the UEFI pstore,
so we don't get to transfer logs. Instead, they accumulate, filling up the
pstore over time, potentially breaking the UEFI variable store.
Let's add a service dependency on any kernel module that can provide a
pstore to ensure we only scan for pstate after we can actually see pstate.
I have seen live occurences of systems breaking because we did not erase
the pstates and ran out of UEFI nvram space.
Fixes https://github.com/systemd/systemd/issues/18540

Subject: [PATCH] pstore: do not try to load all known pstore modules
Commit 70e74a5997 ("pstore: Run after modules are loaded") added After=
and Wants= entries for all known kernel modules providing a pstore.
While adding these dependencies on systems where one of the modules is
not present, or not configured, should not have a real affect on the
system, it can produce annoying error messages in the kernel log. E.g.
"mtd device must be supplied (device name is empty)" when the mtdpstore
module is not configured correctly.
Since dependencies cannot be removed with drop-ins, if a distro wants to
remove some of these modules from systemd-pstore.service, they need to
patch units/systemd-pstore.service.in. On the other hand, if they want
to append to the dependencies this can be done by shipping a drop-in.
Since the original intent of the previous commit was to fix [1], which
only requires the efi_pstore module, remove all other kernel module

Subject: [PATCH] journald: Increase stdout buffer size sooner, when almost
full
If the previous received buffer length is almost equal to the allocated
buffer size, before this change the next read can only receive a couple
of bytes (in the worst case only 1 byte), which is not efficient.

`journalctl --relinquish-var` waits on that file, so we must create if
even if nothing has really happened.

Subject: [PATCH] test: make TEST-35-LOGIN stable again
The expect stuff was anything but expected, so let's just backport
the upstream test case and tweak it a bit to account for the missing
parts in our downstream testing infrastructure.
Follow-up to 638c2418e7.

Subject: [PATCH] pager: set $LESSSECURE whenver we invoke a pager
Some extra safety when invoked via "sudo". With this we address a
genuine design flaw of sudo, and we shouldn't need to deal with this.
But it's still a good idea to disable this surface given how exotic it
is.
Prompted by #5666

Subject: [PATCH] test-login: always test sd_pid_get_owner_uid(), modernize
A long time some function only worked when in a session, and the test
didn't execute them when sd_pid_get_session() failed. Let's always call
them to increase coverage.
While at it, let's test for ==0 not >=0 where we don't expect the function
to return anything except 0 or error.

Subject: [PATCH] pager: make pager secure when under euid is changed or
explicitly requested
The variable is renamed to SYSTEMD_PAGERSECURE (because it's not just about
less now), and we automatically enable secure mode in certain cases, but not
otherwise.
This approach is more nuanced, but should provide a better experience for
users:
- Previusly we would set LESSSECURE=1 and trust the pager to make use of
it. But this has an effect only on less. We need to not start pagers which
are insecure when in secure mode. In particular more is like that and is a
very popular pager.
- We don't enable secure mode always, which means that those other pagers can
reasonably used.
- We do the right thing by default, but the user has ultimate control by
setting SYSTEMD_PAGERSECURE.
Fixes #5666.
v2:
- also check $PKEXEC_UID
v3:
- use 'sd_pid_get_owner_uid() != geteuid()' as the condition
(cherry picked from commit 0a42426d797406b4b01a0d9c13bb759c2629d108)
Resolves: #2175624

Subject: [PATCH] test: ignore ENOMEDIUM error from sd_pid_get_cgroup()
Ubuntu builds on the Launchpad infrastructure run inside a chroot that does
not have the sysfs cgroup dirs mounted, so this call will return ENOMEDIUM
from cg_unified_cached() during the build-time testing, for example when
building the package in a Launchpad PPA.

Subject: [PATCH] ci: first part of the source-git automation - commit linter
Add a GitHub Workflow that is triggered on `workflow_run` events.
It uses metadata provided by `redhat-plumbers-in-action/gather-pull-request-metadata`
GitHub Action to get the PR number and the commit metadata.
The commit metadata is then used to check if the commit message contains
all required information (tracker and upstream reference). GitHub Action
responsible for commit verification `redhat-plumbers-in-action/advanced-commit-linter`
is configured via the `advanced-commit-linter.yml` file.

[msekleta: in our version of systemd "const char path*" argument of
path_join() can't be NULL. Here we don't really want any subdirs paths
passed into move_file(), but we can't just pass NULL pointers because
they will be forwarded to path_join(). Hence, let's just pass "/"
instead.]

Subject: [PATCH] test: Disable LUKS devices from initramfs in QEMU tests
We currently use the host's kernel and initramfs in our QEMU tests.
If the host is running on an encrypted LUKS partition, then the initramfs
will have a crypttab setup looking for the particular root disk it needs to
encrypt before booting into the system.
However, this disk obviously doesn't exist in our QEMU VM, so it turns out
our tests end up waiting for this device to become available, which will
never actually happen, and boot hangs for 90s until that service times out.
[*** ] A start job is running for /dev/disk/by-uuid/01234567-abcd-1234-abcd-0123456789ab (20s / 1min 30s)
In order to prevent this issue, let's pass "rd.luks=0" to disable LUKS in
the initramfs only as part of our default kernel command-line in our QEMU
tests.
This is enough to disable this behavior and prevent the timeout, while at
the same time doesn't conflict with our tests that actually check for LUKS
behavior in the systemd running under test (such as TEST-02-CRYPTSETUP).
Tested: `sudo make -C TEST-02-CRYPTSETUP/ clean setup run`

Subject: [PATCH] sulogin: fix control lost of the current terminal when
default.target is rescue.target
When default.target is rescue.target, exiting from the single-user shell
results in lost of the control of the current terminal. This is because the
operation performed to continue to boot is systemctl default but default.target
is now rescue.target and it is already active. Hence, no new process that
controls the current terminal is created. Users need to make hardware reset to
recover the situation.
This sounds like a bit corner case issue and some might feel configuring
default.target as rescue.target is odd because there are several other ways to
transition to rescue.mode without configuring default.target to rescue.target
such as systemctl rescue or systemd.unit=rescue.target something like
that. However, users unfamiliar with systemd operations tend to come up with
systemctl set-default rescue.target.
To fix this issue, let's transition to default.target only when default.target
is inactive. Otherwise, invoke the single-user shell again to keep control of
the current terminal for users.
This new logic depends on whether D-Bus working well. Exiting without any check
of result of systemctl default could lead to again the control lost of the
current terminal. Hence, add checking results of each D-Bus operations
including systemctl default and invoke the single-user shell if they fail.

Subject: [PATCH] parse-util: in parse_permille() check negative earlier
If 'v' is negative, it's wrong to add the decimal to it, as we'd
actually need to subtract it in this case. But given that we don't want
to allow negative vaues anyway, simply check earlier whether what we
have parsed so far was negative, and react to that before adding the
decimal to it.

Subject: [PATCH] tree-wide: increase granularity of percent specifications all
over the place to permille
We so far had various placed we'd parse percentages with
parse_percent(). Let's make them use parse_permille() instead, which is
downward compatible (as it also parses percent values), and increases
the granularity a bit. Given that on the wire we usually normalize
relative specifications to something like UINT32_MAX anyway changing
from base-100 to base-1000 calculations can be done easily without
breaking compat.
This commit doesn't document this change in the man pages. While
allowing more precise specifcations permille is not as commonly
understood as perent I guess, hence let's keep this out of the docs for
now.

Subject: [PATCH] sd-bus: handle -EINTR return from bus_poll()
In sd_bus_wait(), let's convert EINTR to a return code of 0, thus asking
the caller do loop again and enter sd_bus_process() again (which will
not find any queued events). This way we'll not return an error on
something that isn't really an error. This should typically make sure
things are properly handled by the caller, magically, without eating up
the event entirely, and still giving the caller time to run some code if
they want.
(cherry picked from commit 3022916b4d2483452c3ddbbac9ee7c4372b1cb46)
Resolves: #2172846

Subject: [PATCH] journal-vacuum: count size of all journal files
Currently, active journal files are excluded, which means that vacuuming
may not remove anything even if *MaxUse= has been exceeded.

Subject: [PATCH] resolved: instead of closing DNS UDP transaction fds
right-away, add them to a socket "graveyard"
The "socket graveyard" shall contain sockets we have sent a question out
of, but not received a reply. If we'd close thus sockets immediately
when we are not interested anymore, we'd trigger ICMP port unreachable
messages once we after all *do* get a reply. Let's avoid that, by
leaving the fds open for a bit longer, until a timeout is reached or a
reply datagram received.
Fixes: #17421
(cherry picked from commit 80710ade03d971a8877fde8ce9d42eb2b07f4c47)
Resolves: #2156751

Subject: [PATCH] core/timer: Always use inactive_exit_timestamp if it is set
If we're doing a daemon-reload, we'll be going from TIMER_DEAD => TIMER_WAITING,
so we won't use inactive_exit_timestamp because TIMER_DEAD != UNIT_ACTIVE, even
though inactive_exit_timestamp is serialized/deserialized and will be valid after
the daemon-reload.
This issue can lead to timers never firing as we'll always calculate the next
elapse based on the current realtime on daemon-reload, so if daemon-reload happens
often enough, the elapse interval will be moved into the future every time, which
means the timer will never trigger.
To fix the issue, let's always use inactive_exit_timestamp if it is set, and only
fall back to the current realtime if it is not set.
(cherry picked from commit 6546045fa0bf84737bd8b2e1e8bf7dd3941d8352)

Subject: [PATCH] test-login: skip consistency checks when logind is not active
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
There are two ways in swich sd_login_* functions acquire data:
some are derived from the cgroup path, but others use the data serialized
by logind.
When the tests are executed under Fedora's mock, without systemd-spawn
but instead in a traditional chroot, test-login gets confused:
the "outside" cgroup path is visible, so sd_pid_get_unit() and
sd_pid_get_session() work, but sd_session_is_active() and other functions
that need logind data fail.
Such a buildroot setup is fairly bad, but it can be encountered in the wild, so
let's just skip the tests in that case.
/* Information printed is from the live system */
sd_pid_get_unit(0, …) → "session-237.scope"
sd_pid_get_user_unit(0, …) → "n/a"
sd_pid_get_slice(0, …) → "user-1000.slice"
sd_pid_get_session(0, …) → "237"
sd_pid_get_owner_uid(0, …) → 1000
sd_pid_get_cgroup(0, …) → "/user.slice/user-1000.slice/session-237.scope"
sd_uid_get_display(1000, …) → "(null)"
sd_uid_get_sessions(1000, …) → [0] ""
sd_uid_get_seats(1000, …) → [0] ""
Assertion 'r >= 0' failed at src/libsystemd/sd-login/test-login.c:104, function test_login(). Aborting.
(cherry picked from commit ac5644635dba54ce5eb0ff394fc0bc772a984849)

Subject: [PATCH] sd-event: don't destroy inotify data structures from inotify
event handler
This fixes a bad memory access when we destroy an inotify source handler
from the handler itself, and thus destroy the associated inotify_data
structures.
Fixes: #20177
(cherry picked from commit 53baf2efa420cab6c4b1904c9a0c46a0c4ec80a1)
Resolves: #2211358

Subject: [PATCH] sd-event: add sd_event_add_inotify_fd() call
sd_event_add_inotify_fd() is like sd_event_add_inotify(), but takes an
fd to an inode instead of a path, and is hence a ton nicer.

+# Contributing
+
+Welcome to systemd source-git for CentOS Stream and RHEL. When contributing, please follow the guide below.
+
+## Workflow
+
+```mermaid
+flowchart LR
+ A(Issue) --> B{is fixed\nupstream}
+ B -->|YES| C(backport\nupstream patch)
+ B -->|NO| D(upstream\nsubmit issue or PR)
+ D --> E{accepted\nand fixed}
+ E -->|YES| C
+ E -->|NO| F(rhel-only patch) --> G
+ C --> G(submit PR)
+```
+
+## Filing issues
+
+When you find an issue with systemd used in CentOS Stream or RHEL, please file an issue in [Jira ticket system](https://issues.redhat.com/secure/CreateIssue!default.jspa) (set Project to **RHEL** and Component to **systemd**).
+
+GitHub Issues are not supported tracking system. If your issue is reproducible using the latest upstream version of systemd, please consider creating [upstream issue](https://github.com/systemd/systemd/issues/new/choose).
+
+## Posting Pull Requests
+
+Every Pull Request has to comply with the following rules:
+
+- Each commit has to reference [upstream](https://github.com/systemd/systemd) commit.
+- Each commit has to reference the approved issue/tracker.
+- Pull requests have to pass mandatory CI validation and testing
+- Pull requests have to be approved by at least one systemd downstream maintainer
+
+### Upstream reference
+
+When doing a back-port of an upstream commit, always use `cherry-pick -x <sha>`. Consider proposing a change upstream first when an upstream commit doesn't exist.
+If the change isn't upstream relevant or accepted by upstream, mark the commit with the `rhel-only` string.
+
+```md
+doc: Fix TYPO
+
+rhel-only
+
+Resolves: RHEL-678
+```
+
+### Issue reference
+
+Each commit has to reference the relevant approved systemd issue (see: [Filling issues section](#filing-issues)). For referencing issues, we use the following keywords:
+
+- **Resolves** for commits that directly resolve issues described in a referenced tracker
+- **Related** for commits related to the referenced issue, but they don't fix it. Usually, tests and documentation.
+- **Reverts** for commits that reverts previously merged commit
+
+When referencing issues, use following structure: `<keyword>: <issue ID>`. See the example below:
+
+```md
+doc: Fix TYPO
+

Subject: [PATCH] manager: allow transient units to have drop-ins
In https://github.com/containers/podman/issues/16107, starting of a transient
slice unit fails because there's a "global" drop-in
/usr/lib/systemd/user/slice.d/10-oomd-per-slice-defaults.conf (provided by
systemd-oomd-defaults package to install some default oomd policy). This means
that the unit_is_pristine() check fails and starting of the unit is forbidden.
It seems pretty clear to me that dropins at any other level then the unit
should be ignored in this check: we now have multiple layers of drop-ins
(for each level of the cgroup path, and also "global" ones for a specific
unit type). If we install a "global" drop-in, we wouldn't be able to start
any transient units of that type, which seems undesired.
In principle we could reject dropins at the unit level, but I don't think that
is useful. The whole reason for drop-ins is that they are "add ons", and there
isn't any particular reason to disallow them for transient units. It would also
make things harder to implement and describe: one place for drop-ins is good,
but another is bad. (And as a corner case: for instanciated units, a drop-in
in the template would be acceptable, but a instance-specific drop-in bad?)
Thus, $subject.
While at it, adjust the message. All the conditions in unit_is_pristine()
essentially mean that it wasn't loaded (e.g. it might be in an error state),
and that it doesn't have a fragment path (now that drop-ins are acceptable).
If there's a job for it, it necessarilly must have been loaded. If it is
merged into another unit, it also was loaded and found to be an alias.
Based on the discussion in the bugs, it seems that the current message
is far from obvious ;)
Fixes https://github.com/containers/podman/issues/16107,
https://bugzilla.redhat.com/show_bug.cgi?id=2133792.

Subject: [PATCH] TEST-15: allow helper functions to accept other unit types
clear_services() is renamed to clear_units() and now takes a full
unit name including the suffix as an argument.
_clear_service() is renamed to clear_unit() and changed likewise.
create_service() didn't have the same underscore prefix, and I don't think
it's useful or needed for a local function, so it is removed.
No functional change.

Subject: [PATCH] TEST-15: also test hierarchical drop-ins for slices
Slices are worth testing too, because they don't need a fragment path so they
behave slightly differently than service units. I'm making this a separate
patch from the actual tests that I wanted to add later because it's complex
enough on its own.

Subject: [PATCH] TEST-15: add test for transient units with drop-ins
We want to test four things:
- that the transient units are successfully started when drop-ins exist
- that the transient setings override the defaults
- the drop-ins override the transient settings (the same as for a normal unit)
- that things are the same before and after a reload
To make things more fun, we start and stop units in two different ways: via
systemctl and via a direct busctl invocation. This gives us a bit more coverage
of different code paths.
