Some sd-bus man pages did not have any references on the main
sd-bus man page. Unless you accidentally stumbled on them from
other pages it was difficult to discover them.
The functions `sd_bus_emit_interfaces_added_strv`, `sd_bus_emit_interfaces_removed_strv`
and `sd_bus_emit_properties_changed_strv` take an `char **` not
`const char **` as last argument.
See `src/systemd/sd-bus.h` for the function definition.
We can run sd-ipv4ll/sd-ipv4acd also on an interface with IFF_NOARP
flag, but that may cause address conflict with other hosts.
Let's enable ARPing when sd-ipv4ll/sd-ipv4acd are enabled unless ARP= is
explicitly disabled.
Traditionally, logind installed a fifo in the PAM session and
used EOF on the fd as signal for session close. With the addition of
pidfd (76f2191d8e) however,
logind tracks the leader process and the session is terminated
as soon as that exits. I think the new behavior generally makes
more sense, and the behavior got changed *in the mentioned commit
already* without anyone ever showing up to complain. It hence
feels safe to kill the concept now (also before the varlink interface
gets rolled out).
Note that the 'PID' field in CreateSession() Varlink method
is now marked as strict, i.e. failure to acquire pidfd
is immediately treated as fatal.
To make systemd-udevd not lose received uevents on restart. This may be
important on switching root, even though we typically trigger all devices
after switching root by systemd-udev-trigger.service, but it may be
disabled or modified by admin.
I have been trying to run
https://github.com/include-what-you-use/include-what-you-use on the
systemd repository to hopefully get a handle on the rampant numbers of
includes we have in every file with no idea if any of the symbols coming
from that file are used or not.
While I haven't got it fully working yet, these changes still make sense
IMO and can be merged already.
Except the last commit, all other changes are about removing circular
dependencies between headers which trips up include-what-you-use.
Regardless of the tool, circular dependencies between headers are a code
smell and I think we should get rid of them regardless of whether we end
up using the tool or not.
Even though these are in our tree, we should still treat them as
system includes which helps various tools (clangd, iwyu, ...) understand
that these are system includes and <> should be used instead of "".
Now that the necessary functions from log.h have been moved to macro.h,
we can stop including log.h in macro.h. This requires modifying source
files all over the tree to include log.h instead.
Various functions in log.h are only used by asserts, and there's
enough assertion related stuff in macro.h to justify a separate header
which also makes it easier to avoid circular dependencies.
Let's introduce assert-util.h and an accompanying fundamental header
and move all the assertion related stuff over there. PROJECT_FILE is
moved over to macro.h.
Aligning is closely related to memory management, so let's move these
macros and functions to memory-util-fundamental.h. This will allow us
to move assertion related logic out of macro-fundamental.h as well in
a later commit.
Let's keep macro.h for the extremely generic macros that don't fit anywhere
else. Since CLEANUP_ARRAY() is already in memory-util-fundamental.h, we can
make a good case for moving the other cleanup macros in there as well.
ssh-generator and ssh-proxy are great features, it is very handy to be
able to do:
ssh vsock/1
But, because of the '/' used as a separator, scp and rsync don't
interpret 'vsock/<CID>' as a hostname, e.g.
$ scp /etc/machine-id vsock/2222:.
cp: cannot create regular file 'vsock/2222:.': No such file or directory
$ rsync /etc/machine-id vsock/2222:.
rsync: [Receiver] change_dir#3 "(...)/vsock" failed: No such file or directory (2)
rsync error: errors selecting input/output files, dirs (code 3) at main.c(829) [Receiver=3.4.1]
An alternative is to use ',' as separator, e.g.
$ scp /etc/machine-id vsock,2222:.
This is what is being suggested here. The names with '/' are kept not to
break anything here.
Others are possible: '%', '=', '#', '@', ':', etc. As mentioned in
commit 0abd510f7f ("ssh-proxy: add ssh ProxyCommand tool that can
connect to AF_UNIX + AF_VSOCK sockets"), it is better to avoid ':' as it
is already taken by SSH itself when doing sftp, and "@" is already taken
for separating the user name. '#' will cause some issues with some
shells like ZSH when quotes are not used.
Currently, all use cases of notify_push_fd()/notify_push_fdf()
assume that the name of each fd in the fdstore is unique.
For safety, let's remove the existing fds before pushing a new one
to avoid multiple fds with the same name stored in the fdstore.
