[Cluster-devel] [PATCHv3 dlm-tool 0/4] dlm_controld: support for mark and waitplock_recovery

[Alexander Aring <aahringo@redhat.com>]

Hi,

this patch series adds support for set the in-kernel socket skb mark
value over dlm_controld. There exists two kinds of socket, one listen
socket and multiple peer sockets. Both can be set via the dlm config
file via "listen_mark" or multiple entries of:

node id=$NODEID mark=$MARK

whereas $NODEID is the corosync assigned nodeid. The given mark number
can be hexadecimal or decimal.

Also it adds support to set the waitplock_recovery per cluster attribute
by setting enable_waitplock_recover over file or argument configuration.

- Alex

changes since v3:
 - add support for unsigned int default values
 - changed default value of boolean arg enable_waitplock_recover from 1
   to 0. dlm_controld was not using the default value anyway, because
   there exists a check to ignore default values and only set it when
   it's set. I changed it anyway to be consistent.
 - Let mark per node config don't abort the whole node configuration
   if open fails (e.g. older kernel) instead we skip now to try to set
   the mark value. It will show up in the log that open fails.

changes since v2:
 - remove leftover PRIu32 in nodeid configuration
 - make unsigned int values also work with file configuration, was arg
   only before
 - add support to set the waitplock_recovery switch via dlm_controld
 - remove free function of node_config, may be necessary when implement
   some kind of NOHUP and reparse config file
