commit b8ecf4ddd6533437020c4589a6f7bcd9a62307ad

sk: Handle EINTR when waiting for transmit timestamp.
If ptp4l received a signal in poll() waiting for a transmit timestamp,
multiple (possibly confusing) error messages are logged before exit.
If poll() returns with EINTR, call it once again to get the timestamp
and avoid logging the errors. Don't call it in a loop to avoid getting
stuck in case the timestamp is lost and the signal is repeated before
the poll timeout can be reached.

commit 134dc3c4655fcd9f314a5e56cd50db2f87366f5a

Don't re-arm fault clearing timer on unrelated netlink events
Set the timer only when an event causes the port to transition to the
FAULTY state, rather than potentially re-arming the timeout when an
event occurs while the port was already FAULTY.
Concretely this occurs when a port is in fault, perhaps due to a
single time out while polling for tx-timestamp. If any other port in the
system (including unrelated ones ptp4l does not even know about) cause
netlink messages to be sent. As it stands, clock_poll() will note that
the port is in fault (from before, not due to the current event) and
reset the timeout to its original value.
If such unrelated netlink messages arrive at a regular enough cadence
the timeout may be repeatedly reset, not trigger on time (if at all) and
the port may not get a chance to clear its fault, perhaps indefinitely.

commit 2db8da6d1e3db074c01516c74899d42089039bc8
Author: Miroslav Lichvar <mlichvar@redhat.com>
Date: Wed Apr 26 13:45:41 2023 +0200
Clear pending errors on sockets.
When the netlink socket of a port (used for receiving link up/down
events) had an error (e.g. ENOBUFS due to the kernel sending too many
messages), ptp4l switched the port to the faulty state, but it kept
getting POLLERR on the socket and logged "port 1: unexpected socket
error" in an infinite loop.
Unlike the PTP event and general sockets, the netlink sockets cannot be
closed in the faulty state as they are needed to receive the link up event.
Instead, receive and clear the error on all descriptors getting POLLERR
with getsockopt(SO_ERROR). Include the error in the log message together
with the descriptor index to make it easier to debug issues like this in
future.
(Rebased to 3.1.1)
