3e5f04bf64 was trying to do the right thing, but
the resulting list does not match the autogenerated order (which is the same as
the order in vtable definition). I assume the addition was done manually. Fix
the order so that dbus-docs-fresh test is not unhappy.
With new directive SystemCallLog= it's possible to list system calls to be
logged. This can be used for auditing or temporarily when constructing system
call filters.
---
v5: drop intermediary, update HASHMAP_FOREACH_KEY() use
v4: skip useless debug messages, actually parse directive
v3: don't declare unused variables with old libseccomp
v2: fix build without seccomp or old libseccomp
Define explicit action "kill" for SystemCallErrorNumber=.
In addition to errno code, allow specifying "kill" as action for
SystemCallFilter=.
---
v7: seccomp_parse_errno_or_action() returns -EINVAL if !HAVE_SECCOMP
v6: use streq_ptr(), let errno_to_name() handle bad values, kill processes,
init syscall_errno
v5: actually use seccomp_errno_or_action_to_string(), don't fail bus unit
parsing without seccomp
v4: fix build without seccomp
v3: drop log action
v2: action -> number
Mention the JSON user record stuff. Mention pam_umask explicitly.
Mention that UMask= of the per-user user@.service instance can be used
too.

Heavily inspired by #15622. This adds:
systemctl service-log-level systemd-resolved
systemctl service-log-level systemd-resolved info
systemctl service-log-target systemd-resolved
systemctl service-log-target systemd-resolved console
We already have systemctl verbs log-level, log-target, and service-watchdogs.
Those two new verbs tie nicely into this scheme.
The manual states that a persistent timer triggers it's service
immediately on activation to catch up with missed invocations, but since
PR #11608 it is no longer the case if RandomizedDelaySec= is set to a
non-zero value.
Closes#12624.
The formatting in systemd.socket.xml is updated a bit.
Currently in_addr_port_ifindex_name_to_string() always prints the ifindex
numerically. This is not super useful since the interface numbers are
semi-random. Should we use interface names in preference?
KEY_RESTART is widely used in Linux to indicate device reboot.
So lets handle it in the same fashion as KEY_POWER.

The list was rather ad hoc, with "reset-failed" sandwiched between
"help" and "list-dependencies". Since a person will usually either want
to introspect state in various ways or modify state in a certain way, let's
put all the introspection commands together and all the ones that actually
have an effect second.
sd_seat_get_sessions() would return 0 in the 'n_uids' (now 'ret_n_uids') output
parameter when 'uid' (now 'ret_uids') was passed as NULL.
While at it, drop FOREACH_WORD() use.
Also use any whitespace as separator. In practice this shouldn't matter, since
logind always uses spaces, but it seems nicer to not specify this explicitly,
and the default is more flexible.
The new methods work as the unflavoured ones, but takes flags as a
single uint64_t DBUS parameters instead of different booleans, so
that it can be extended without breaking backward compatibility.
Add new flag to allow adding/removing symlinks in
[/etc|/run]/systemd/system.attached so that portable services
configuration files can be self-contained in those directories, without
affecting the system services directories.
Use the new methods and flags from portablectl --enable.
Useful in case /etc is read-only, with only the portable services
directories being mounted read-write.
Let's make sure the sd_listen_fd() docs are really found from the
.socket file documentation as well as the FileDescriptorStoreMax=
documentation.
Let's also emphasize that that's where the order in which the fds are
passed are documented.
Fixes: #16647
I started working on a command-line switch to show passwords also in
"pretty" mode. I can submit that code for review if anyone thinks that
woul be useful, but after writing the man page I realized that it's a
fairly niche case, and the hint in the man page is a sufficient
replacement.
Let's document the discrepancy between the Sec and USec suffixing of
unit files and D-Bus properties at three places: in "systemctl show"
(where it already was briefly mentioned), in the D-Bus interface
description (at one place at least, i.e. the most prominent of
properties that encapsulate time values, there are many more) and in the
general man page explaining time values.
By documenting this at all three places I think we now do as much as we
can do about this highlighting the discrepancy of the naming and the
reasons behind it.
Fixes: #2047
This makes use of the developer mode switch: the test is only done
if the user opted-in into developer mode.
Before the man/update-dbus-docs was using the argument form where
we don't need to run find_command(), but that doesn't work with test(),,
so find_command() is used and we get one more line in the config log.
The fix from cb263973ac was made the other way around,
i.e. `SIGKILL` was changed to `SIGUSR1`, but the sentence is about a "termination signal", i.e. `SIGKILL`, not `SIGUSR1`.
Commands like build/man/man journald.conf.d would show the installed
man page (or an error if the page cannot be found in the global search
path), and not the one in the build directory. If the man page is
a redirect, or the .html is a symlink, resolve it, build the target,
and show that.
Follow the same model established for RootImage and RootImageOptions,
and allow to either append a single list of options or tuples of
partition_number:options.
The concept is flawed, and mostly useless. Let's finally remove it.
It has been deprecated since 90a2ec10f2 (6
years ago) and we started to warn since
55dadc5c57 (1.5 years ago).
Let's get rid of it altogether.
Timestamps for unit start/stop are recorded with microsecond granularity,
but status and show truncate to second granularity by default.
Add a --timestamp=pretty|us|utc option to allow including the microseconds
or to use the UTC TZ to all timestamps printed by systemctl.
Apparently both Fedora and suse default to btrfs now, it should hence be
good enough for us too.
This enables a bunch of really nice things for us, most importanly we
can resize home directories freely (i.e. both grow *and* shrink) while
online. It also allows us to add nice subvolume based home directory
snapshotting later on.
Also, whenever we mention the three supported types, alaways mention
them in alphabetical order, which is also our new order of preference.
The description didn't really explain how the distribution mechanism
works exactly and the relationship of leaf and slice units.
Update the documentation and also explicitly explain the expected
behaviour as it is created by the memory_recursiveprot cgroup2 mount
option.
This comes up occasionally with new users. The phrase "Logs begin ..." is
ambiguous because it can be taken to mean the logs being displayed or all logs
(the intended meaning). Let's rephrase this as "Journal begins ..." to make
this clearer.
I am pretty sure /etc/hosts (i.e. an explicitly configured, local,
trusted database) should be useful for overriding the automatic
myhostname logic.
resolved's internal logic handles it that way and hence we should
suggest it in the NSS fallback line, too.
Let's also bring the factory file back into sync with what the docs say.
And update the prose a bit too, to actually match what we recommend.
Follows the same pattern and features as RootImage, but allows an
arbitrary mount point under / to be specified by the user, and
multiple values - like BindPaths.
Original implementation by @topimiettinen at:
https://github.com/systemd/systemd/pull/14451
Reworked to use dissect's logic instead of bare libmount() calls
and other review comments.
Thanks Topi for the initial work to come up with and implement
this useful feature.
