* | tree-wide: drop _pure_ attribute from non-pure functionsYu Watanabe2023-05-101-1/+1
| | | | | | | | | | Prompted by #27595. Follow-ups for 6723c28f36ea566faf61d3610012cd89f95ee4a0.
* | dirent: conditionalize dirent assert based on dirent64 existenceSam James2023-05-101-0/+2
|/ | | | | | | | | | >=musl-1.2.4 doesn't define dirent64 and its LFS friends as its "native" functions are already LFS-aware. Check for dirent64 in meson.build and only assert if it exists. Bug: https://bugs.gentoo.org/905900 Closes: https://github.com/systemd/systemd/pull/25809

* parse-util: make parse_fd() return -EBADFYu Watanabe2023-05-081-1/+1
| | | | | | | | The previous error code -ERANGE is slightly ambiguous, and use more specific one. This also drops unnecessary error handlings. Follow-up for 754d8b9c330150fdb3767491e24975f7dfe2a203 and e652663a043cb80936bb12ad5c87766fc5150c24.
* basic/audit-util: make a test request before enabling use of auditNick Rosbrook2023-05-051-1/+60
| | | | | | | | | | | | | | | | | | If a container manager does not follow the guidance in https://systemd.io/CONTAINER_INTERFACE/ regarding audit capabilities, then the current check may not be sufficient to determine that audit will function properly. In particular, when calling bind() on the audit fd, we will get EPERM if running in a user-namespaced container. Expand the check to make an AUDIT_GET_FEATURE request on the audit fd to test if it is working. If this fails with ECONNREFUSED, we know it is because the kernel does not support the use of audit outside of the initial user namespace. Note that the approach of this patch was suggested here: https://github.com/systemd/systemd/pull/19443#issuecomment-829566659 Fixes: #6519

| | | | | | | | | | | | The kernel has had filesystem independent reflink ioctls for a while now, let's try to use them and fall back to the btrfs specific ones if they're not supported.
* | cgroup: rework how we validate/escape cgroupsLennart Poettering2023-04-272-45/+57
| | | | | | | | | | | | Let's clean up validation/escaping of cgroup names. i.e. split out code that tests if name needs escaping. Return proper error codes, and extend test a bit.

| | | | | | | | | | | | | | | | | | | | | | | | | | 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. root@image:~# systemd-run -t --property CoredumpFilter=all ls /tmp Running as unit: run-u13.service Press ^] three times within 1s to disconnect TTY. *** stack smashing detected ***: terminated [137256.320511] systemd[1]: run-u13.service: Main process exited, code=dumped, status=6/ABRT [137256.320850] systemd[1]: run-u13.service: Failed with result 'core-dump'.

| * | | basic/logarithm: add popcount() wrapperZbigniew Jędrzejewski-Szmek2023-04-241-53/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | __builtin_popcount() is a bit of a mouthful, so let's provide a helper. Using _Generic has the advantage that if a type other then the ones on the list is given, compilation will fail. This is nice, because if by any change we pass a wider type, it is rejected immediately instead of being truncated. log.h is also needed. It is included transitively, but let's include it directly. macro.h is *not* needed.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is the function version of STARTSWITH_SET(). We also move STARTSWITH_SET() to string-util.h as it fits more there than in strv.h and reimplement it using startswith_strv().
| * | | | log: Log when kmsg is being ratelimitedDaan De Meyer2023-04-201-2/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Let's avoid confusing developers and users when log messages suddenly stop getting logged to kmsg because of ratelimiting by logging an additional message if we start ratelimiting log messages to kmsg.
| * | | | log: Add knob to disable kmsg ratelimitingDaan De Meyer2023-04-201-1/+21

* | | | ratelimit: handle counter overflows somewhat sanelyLennart Poettering2023-04-201-9/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | An overflow here (i.e. the counter reaching 2^32 within a ratelimit time window) is not so unlikely. Let's handle this somewhat sanely and simply stop counting, while remaining in the "limit is hit" state until the time window has passed.

* | | | chase: replace path_prefix_root_cwd() with chaseat_prefix_root()Yu Watanabe2023-04-195-31/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The function path_prefix_root_cwd() was introduced for prefixing the result from chaseat() with root, but - it is named slightly generic, - the logic is different from what chase() does. This makes the name more explanative and specific for the result of the chaseat(), and make the logic consistent with chase(). Fixes https://github.com/systemd/systemd/pull/27199#issuecomment-1511387731. Follow-up for #27199.
* | | | fd-util: skip to check mount ID if kernel is too old and /proc is not mountedYu Watanabe2023-04-191-7/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now, dir_fd_is_root() is heavily used in chaseat(), which is used at various places. If the kernel is too old and /proc is not mounted, then there is no way to get the mount ID of a directory. In that case, let's silently skip the mount ID check. Fixes https://github.com/systemd/systemd/pull/27299#issuecomment-1511403680.
