Yu Watanabe 67040ea2bc More legacy kernel support removal; follow-ups for XAT_FDROOT (#40384) 2026-01-19 23:10:17 +09:00
zefr0x 985a6fa44b busctl: handle --limit-messages option under the wait verb 
Main focus was to not introduce breaking change or duplicated argument.
The `--limit-messages=` option that is used under the `monitor` verb is
reused here. However, both `wait` and `monitor` have contradicting
default behaviors, so it's not the cleanest thing to do.

There was some post-commit discussion about the API in #33961, but the
final name adopted in #34928 wasn't that flexible either to fit nicely
here in the `wait` verbe.

Additionally, there wasn't consideration in #34555 for having uniform
behavrious, so we ended with `wait` verb and `--limit-messages=` option,
rather than `receive` verb with default of continuously receving signals
withtout exit so `--limit-messages=` make more sence and be expectable.

Mike Yuan 1a0df07843 core/cgroup: obsolete DefaultMemoryMin/Low= 
Now that our kernel baseline is v5.7 and memory_recursiveprot
is universally enabled, remove userspace workarounds.

Mike Yuan d57fdbb5e2 core/cgroup: do not consider cgroup_context_has_io_config() if only IOAccounting=yes 
This makes things in line with unit_has_memory_config(),
and suppresses pointless application of IO configs.

cyclopentane 465f6a6284 cryptenroll,cryptsetup,shutdown: only call mlockall if we have CAP_IPC_LOCK 
Calling mlockall in an unprivileged process most notably had the effect
of making systemd-cryptenroll OOM while trying to open a normal-sized
argon2 keyslot due to it hitting RLIMIT_MEMLOCK.

Mike Yuan bbce82dfab core/unit: drop unneeded unit_modify_nft_set() call during coldplug 
We re-realize all unit cgroups upon daemon-reload, and
cgroup_context_apply() would take care of NFT set refreshing.
No need to duplicate that in unit_coldplug().

Yu Watanabe 112cbc3790 journal-file: do not trigger assertion on removed or corrupted journal file 
When a journal file is removed or corrupted, then the value `p`, which is
read from Object.data.entry_offset, may be zero.

Note, journal_file_move_to_object() checks the passed offset and return
-EBADMSG if it is invalid.

Fixes the issue reported at
https://github.com/systemd/systemd/pull/40372#issuecomment-3762907261.

Mike Yuan 12effc32da core/unit: several cleanups for unit_queue_job_check_and_collapse_type() 
* Rename to _mangle_type() - it turned out this one doesn't collapse
  anything, but rather mangles the type if reload_if_possible is set.
  Hence name accordingly.
* Use -ELIBEXEC rather than -EUNATCH to denote dependency only units.
* Add a comment about the JOB_STOP and load state check.
