Add CC0 as the license. SPDX does not have a "public domain" tag, but CC0 is
more or less equivalent. We should have *some* header to avoid doubts in the
future.
After upgrading to emacs-26.1-1.fc28.x86_64 I noticed that our
.dir-locals.el files weren't honoured anymore (specifically the fill
column variable is not correctly set for c-mode files). I finally
tracked this down to the order in which items are listed in
.dir-locals.el: if the "nil" one is listed last everything works,
otherwise, it's the one that is applied instead of the c-mode one.
This patch simply swaps the entries, and puts the "nil" one last. My
emacs lisp fu is a bit too limited to understand the full impact for
this, and why emacs 26.1 changed behaviour in this regard, but from an
outsider's view the order shouldn't negatively affect things otherwise,
hence this patch.
This bumps the minimum required version of meson to 0.45 and
python to 3.5, as integer type option is supported since meson-0.45
and meson-0.45 requires python-3.5.
This adds -Dnss-resolve= and -Dnss-mymachines= meson options.
By using this option, e.g., resolved can be built without nss-resolve.
When no nss modules are built, then test-nss is neither built.
Also, This changes the option name -Dmyhostname= to -Dnss-myhostname=
for consistency to other nss related options.
Closes#9596.
Usecase is to allow changing the final kill from SIGKILL to SIGQUIT which
should create a core dump useful for debugging why the service didn't stop
with the SIGTERM
Using `getent' and `id' command in case of cross compiling does not
make much sense. This is because it is the host files that are checked.
Besides, in some restricted cross compilation environment, these two
command may not even be available. This is to avoid host comtamination.
So we should only check the validity using getent and id when not
cross compiling.
That call to mount was added as a safeguard against a kernel bug which was fixed in
torvalds/linux@bbd5192.
In principle, the error could be ignored because
* normally everything mounted on /proc/PID should disappear as soon as the PID has gone away
* test-mount-util that had been confused by those phantom entries in /proc/self/mountinfo was
taught to ignore them in 112cc3b.
On the other hand, in practice, if the mount fails, then the next one is extremely unlikely to
succeed, so it seems to be reasonable to just skip the rest of `test_get_process_cmdline_harder`
if that happens.

Currently to set the flag to reboot into the firmware setup an
authentication by an administrative user is required. Since we are
already enabling active users to reboot the system, it is advisable to
let the user decide if he wants to boot into the firmware setup without
any more hassle.
Currently, mount_sysfs() only creates /sys/fs/cgroup if cg_ns_supported().
The comment explains that we need to "Create mountpoint for
cgroups. Otherwise we are not allowed since we remount /sys read-only.";
that is: that we need to do it now, rather than later. However, the
comment doesn't do anything to explain why we only need to do this if
cg_ns_supported(); shouldn't we _always_ need to do it?
The answer is that if !use_cgns, then this was already done by the outer
child, so mount_sysfs() only needs to do it if use_cgns. Now,
mount_sysfs() doesn't know whether use_cgns, but !cg_ns_supported() implies
!use_cgns, so we can optimize" the case where we _know_ !use_cgns, and deal
with a no-op mkdir_p() in the false-positive where cgns_supported() but
!use_cgns.
But is it really much of an optimization? We're potentially spending an
access(2) (cg_ns_supported() could be cached from a previous call) to
potentially save an lstat(2) and mkdir(2); and all of them are on virtual
fileystems, so they should all be pretty cheap.
So, simplify and drop the conditional. It's a dubious optimization that
requires more text to explain than it's worth.
Remove "arbitrary named hierarchies" from the list of things that
cg_kernel_controllers() might return, and clarify that "name="
pseudo-controllers are not included in the returned list.
/proc/cgroups does not contain "name=" pseudo-controllers, and
cg_kernel_controllers() makes no effort to enumerate them via a different
mechanism.
