[CRIU] ERROR -2 reported by netlink (No such file or directory)

[Adrian Reber]

Hello Cyrill,

I saw a few commits from you related to 'inet: raw'. I hope you are the
right person for my problem. On my RHEL7 system I get following line in
CRIU's dump.log:

# (00.004061) unix: 	Collected: ino 75689 peer_ino 0 family    1 type    5 state  7 name (null)
# (00.004170) Error (criu/libnetlink.c:27): ERROR -2 reported by netlink (No such file or directory)
# (00.004176) Warn  (criu/sockets.c:791): sockets: The current kernel doesn't support ipv4 raw_diag module
# (00.004271) Error (criu/libnetlink.c:27): ERROR -2 reported by netlink (No such file or directory)
# (00.004274) Warn  (criu/sockets.c:834): sockets: The current kernel doesn't support ipv6 raw_diag module

As I am currently looking at the CRIU test cases from runc I now
get test case failures because of this. The test cases does the
following:

run grep -B 5 Error ./work-dir/dump.log -q

Which means that the test case now fails because there is the
string 'Error' in CRIU's log file. This only seems to happen
with criu-dev and not with 3.11.

If you are the right person to talk about this, any ideas how
to avoid the runc test failures? There are not real failures,
but still the test fails.
