When suppressing duplicate fields between files we so far tried to reuse
the already known hash value of the data fields between files. This was
fine as long as we used the same hash function everywhere. However,
since addition of the keyed hash feature for journal files this doesn't
work anymore, since the hashes will be different for different files.
Fixes: #19172
This makes the followings:
- reduces scope of variables,
- drop unnecessary 'else'
- use CLOSE_AND_REPLACE() macro
- use strnull() for possible NULL string
If we have BPF_F_ALLOW_MULTI support we can install the new program
before we drop the old (because we can install two program at the same
time). Let's do that, and thus fully close the firewall
gap.
E.g. nexthop requires IFF_UP flag, but the currently stored flag may be
outdated if we called link_down(). This makes such requests pending if
at least one of the flags are updating.
On carrier lost, then all requests which require carrier will not be
processed. And they will be processed when the interface gained its
carrier again. So, it is not necessary to drop requests here.
Previously, IPv6LinkLocalAddressGenerationMode= is not set, then we
define the address generation mode based on the result of reading
stable_secret sysctl value. This makes the mode is determined by whether
a secret address is specified in the new setting.
Closes#19622.
Mostly logging related: let's downgrade logging in dlopen_bpf() for
example, and remove duplicate logging at various places. Add %m to log
messages and so on.
These are so many runtime objects, let's add a bpf_firewall_close()
helper that destroys them all, and call that from unit_free(), simply as
an excercise of encapsulating more BPF code in bpf-firewall.c.
This also brings the destruction order and variable declaration order in
struct Unit into the same systematic order.
No change in behaviour just some minor refactoring.
In dns_server_unlink_marked() and dns_server_mark_all() we done recursively.
People might have dozens of servers defined, and it's better to avoid recursion
when a simple loop suffices.
dns_server_unlink_marked() would only unmark the first marked server.
Fixes#19651.
Journal files have space allocated in 8MiB-aligned increments.
This can add up to substantial wasted space as many archived journals
accumulate without using all the allocated space.
This commit introduces truncating to the offset a subsequent append
would get written at when archiving.

Not sure, but at the time the target partition device is created or
enumerated, some sysattrs or properties may not be ready.
So, let's find partition on timeout. The device may be ready at that
time.
For "systemd-tmpfiles --cleanup", when the "Age" parameter
is specified, the criteria for deletion is determined from
the path's last modification timestamp ("mtime"), its last
access timestamp ("atime") and its last status change
timestamp ("ctime").
For instance, if one of those paths to be cleaned up are
opened, it results in the modification of "atime", which
results file system entry to not be removed because the
default aging algorithm would skip the entry.
Add an optional "age-by" argument by extending the "Age"
parameter to restrict the clean-up for a particular type
of file timestamp, which can be specified in "tmpfiles.d"
as follows:
[age-by:]cleanup-age, where age-by is "[abcmACBM]+"
For example:
d /foo/bar - - - abM:1m -
Would clean-up any files that were not accessed and created,
or directories that were not modified less than a minute ago
in "/foo/bar".
Fixes: #17002
Add the '=' action modifier that instructs tmpfiles.d to check the file
type of a path and remove objects that do not match before trying to
open or create the path.

When using top level drop-ins it isn't immediately obvious that one can
make use of symlinking to disable a top-level drop in for a specific
unit.

When e.g. tmp.mount is present in the initrd, and we serialize it, switch root,
and deserialize, the new systemd is confused because it thinks /tmp is mounted.
In general, it doesn't make sense to serialize anything that refers to paths in
the old root file system.
This fixes two errors for me:
1. tmp.mount was not mounted properly before local-fs.target. It would be
mounted as some point (I guess when we re-read /proc/self/mountinfo for some
other reason). In effect systemd-tmpfiles-setup.service would see one fs, and
some other units started later a different one. In particular gdm.service would
fail because the pre-created /tmp/.X11-unix with proper permissions would not
exist at time it was started.
2. # systemd[1]: proc-sys-fs-binfmt_misc.automount: Got hangup/error on autofs pipe from kernel. Likely our automount point has been unmounted by someone or something else?
# systemd[1]: proc-sys-fs-binfmt_misc.automount: Failed with result 'unmounted'.

I couldn't understand the error here, but in retrospect the first line is entirely
correct: "someone or something else" was the old systemd unmounting the old root.
