If a FREEZE operation takes too long, the driver may time out and move on
to another operation. The daemon is unaware of this and attempts to
notify the driver that the FREEZE succeeded. This results in an error from
the driver and the daemon leaves the filesystem in frozen state.Fix this by thawing the filesystem and continuing.

This script helps to create bonding network devices based on synthetic NIC
(the virtual network adapter usually provided by Hyper-V) and the matching
VF NIC (SRIOV virtual function). So the synthetic NIC and VF NIC can
function as one network device, and fail over to the synthetic NIC if VF is
down.Mayjor distros (RHEL, Ubuntu, SLES) supported by Hyper-V are supported by
this script.Signed-off-by: Haiyang Zhang

Under high memory pressure and very high KVP R/W test pressure, the netlink
recvfrom() may transiently return ENOBUFS to the daemon -- we found this
during a 2-week stress test.We'd better not terminate the daemon on the failure, because a typical KVP
user will re-try the R/W and hopefully it will succeed next time.We can also ignore the errors on sending.

When ioctl(fd, FIFREEZE, 0) results in an error we cannot report it
to syslog instantly since that can cause write to a frozen disk.
However, the name of the filesystem which caused the error and errno
are valuable and we would like to get a nice human-readable message
in the log. Save errno before calling vss_operate(VSS_OP_THAW) and
report the error right after.Unfortunately, FITHAW errors cannot be reported the same way as we
need to finish thawing all filesystems before calling syslog().We should also avoid calling endmntent() for the second time in
case we encountered an error during freezing of '/' as it usually
results in SEGSEGV.Signed-off-by: Vitaly Kuznetsov

All tools/hv daemons do mandatory daemon() on startup. However, no pidfile
is created, this make it difficult for an init system to track such daemons.
Modern linux distros use systemd as their init system. It can handle the
daemonizing by itself, however, it requires a daemon to stay in foreground
for that. Some distros already carry distro-specific patch for hv tools
which switches off daemon().Introduce -n/--no-daemon option for all 3 daemons in hv/tools. Parse options
