Allocating a pty is done in a couple of places so let's introduce a new helper
which does the job.
Also the new function, as well as openpt_in_namespace(), returns both pty
master and slave so the callers don't need to know about the pty slave
allocation details.
For the same reasons machine_openpt() prototype has also been changed to return
both pty master and slave so callers don't need to allocate a pty slave which
might be in a different namespace.
Finally openpt_in_namespace() has been renamed into
openpt_allocate_in_namespace().
The console tty is now allocated from within the container so it's not
necessary anymore to allocate it from the host and bind mount the pty slave
into the container. The pty master is sent to the host.
/dev/console is now a symlink pointing to the pty slave.
This might also be less confusing for applications running inside the container
and the overall result looks cleaner (we don't need to apply manually the
passed selinux context, if any, to the allocated pty for instance).
fstat(2) is fine with O_PATH fds.
For changing owership of a file opened with O_PATH, there's fchownat(2).
Only changing permissions is problematic but we introduced fchmod_opath() for
that purpose.
Since kernel 5.2 the kernel thankfully returns proper errors when we
write a value out of range to the sysctl. Which however breaks writing
ULONG_MAX to request the maximum value. Hence let's write the new
maximum value instead, LONG_MAX.

Fixes: #12803
This is for 6d36464065. It turns out that this is causing more problems than
expected. Let's retroactively introduce naming scheme v241 to conditionalize
this change.
Follow-up for #12792 and 6d36464065. See also

This reflect its role better.
(I didn't use …_persistent_name(), because which name is actually used
depends on the policy. So it's better not to make this sound like it returns
*the* persistent name.)
This is in preparation for later changes. Let's change the documentation of
net.naming-scheme= to also say that it applies to MAC addresses. This commit
doesn't actually implement that though.
This reverts commit 18bddeaaf2.
Revert this because it does not take the OpenSSL internal read pointer
into considoration. Resulting in padding in packetdata and therefore
broken SSL connections.
Coverity is unpredictable and, according to a notification I received
yeserday, it will be upgraded on June 17. During the upgrade
it might be offline for 3 days, af far as I understand. Anyway, Travis
stops as soon as a stage fails so it makes sense to put stages that
are likely to fail at the end so that the others have a chance to
do what they are supposed to do.
https://community.synopsys.com/s/topic/0TO2H0000001CN7WAM/coverity-scan-status
includes two travis ci steps:
1) Every pull-request/push all fuzzing targets will do a quick
sanity run on the generated corpus and crashes (via Fuzzit)
2) On a daily basis the fuzzing targets will be compiled (from
master) and will and their respectible fuzzing job on Fuzzit
will be updated to the new binary.
Otherwise, the interface cannot be in "configured" state, as ipv6 link local
addressing is enabled by default. Note that even if ConfigureWithoutCarrier=
is set, all dynamic configurations are checked when the interface has
carrier.
