1fae121b22 lvmlockd: fix sending debug info to lvmlockctl
Single messages sent over unix sockets are limited in
size to /proc/sys/net/core/wmem_max, so send the 1MB
debug buffer in smaller chunks to avoid EMSGSIZE.

Also look for EAGAIN and retry sending for a limited
time when the reader is slower than the writer.

Also shift the location of that code so it's the same
as other requests.

5476ee8655 cmirrord: avoid resync buffer overflow in LOG_SPRINT
Use snprintf() instead of sprintf() to exclude the possibility of
overflowing the resync history buffers.

1ea1cb6dc9 cmirrord: fix stack smashing
With clusters larger than 3 nodes, the 32-byte debug buffer in
cpg_join_callback() is too small to contain all the node IDs, because
32-bit identifiers are generally rendered in 10 decimal digits.  No fixed
size is good in all cases, but this is conditionally logged debug info,
so we can simply truncate it.  Double the size, nevertheless.

386e91addb libdm: add dm_message_supports_precise_timestamps()
Add a function to test whether the kernel precise_timestamps
feature is available in the current device-mapper driver version.

Presence of precise_timestamps also implies the availability of
latency histograms.

ce2e60ab45 lvmlockd: change log_error to log_debug for non error
It's not uncommon for a command like vgchange -an to
deactivate and unlock LVs that were not active, so
don't lock that as an error.

7b570840cd lockd: no error when unlock fails
The unlock call will fail in expected and normal cases,
and should not cause the command to fail.  (An actual
unlock in the lock manager should never fail.)

We already use -lm functions in a couple of places (these are

check and explicitly link to -lm.

Since we use 'strncpy' even for case where it exactly matches
the buffer size and \0 is not expected to be added there.

12acf852c5 dmsetup: check timerfd reads for valid byte count (Coverity)
The timerfd guarantees that it will return 8 bytes when a read(2)
is issued (a uint64_t giving the number of timer events during the
call). Check that it does so and log a non-fatal error if the byte
count is not 8.
