netsniff-ng: also capture if NIC is currently down
There is actually no reason why netsniff-ng should fail if the NIC is down at startup. We still can setup everything and already capture at the time it goes up. This might be useful when replugging cables on servers, for instance. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>

by fsync after rename and new inode") reverted. This change avoids the fallback to a transaction commit and instead makes sure all the names of the conflicting inode (the one that had a name in a past transaction that matches the name of the new file in the same parent directory) are logged so that at log replay time we don't lose neither the new file nor the old file, and the old file gets the name it was renamed to. This also ends up avoiding a full transaction commit for a similar case that involves an unlink instead of a rename of the old file: at transaction N create file A at directory D at transaction N + M (where M >= 1) remove file A create a new file named A at directory D fsync the new file power fail Signed-off-by: Filipe Manana <fdmanana@suse.com>
