If PCMCIA is still being looked after, then here's
another for you, maybe for 2.6.37.

Use the more descriptive logging message styles.

There are whitespace/indentation errors in the original
sources that these changes do not modify, so checkpatch
errors were cheerfully ignored.

There is no need to check "s".  nla_data() doesn't return NULL.  Also we
already dereferenced "s" at this point so it would have oopsed ealier if

Joe Perches baeb2ffab4 drivers/net: Convert unbounded kzalloc calls to kcalloc
These changes may be slightly safer in some instances.

There are other kzalloc calls with a multiply, but those
calls are typically "small fixed #" * sizeof(some pointer)"
and those are not converted.

Allan Stephens 5a68d5ee00 tipc: Prevent missing name table entries when link flip-flops rapidly
Ensure that TIPC does not re-establish communication with a
neighboring node until it has finished updating all data structures
containing information about that node to reflect the earlier loss of
contact.  Previously, it was possible for TIPC to perform its purge of
name table entries relating to the node once contact had already been
re-established, resulting in the unwanted removal of valid name table
entries.

Allan Stephens 564e83b51a tipc: Allow connect() to wait indefinitely
Cause a socket whose TIPC_CONN_TIMEOUT option is zero to wait
indefinitely for a response to a connection request using connect().
Previously, specifying a timeout of 0 ms resulted in an immediate
timeout, which was inconsistent with the behavior specified by Posix
for a socket's receive and send timeout.

Allan Stephens 0048b826af tipc: Fix bug in broadcast link transmit statistics computation
Modify TIPC's broadcast link so that it counts each piece of a
fragmented message individually, rather than as treating the group
as a single message.  This ensures that proper correlation of sent
and received traffic can be done when the broadcast link statistics
are displayed, and is consistent with the way fragments are counted
by TIPC's unicast links.

Allan Stephens 5b1f7bdeb6 tipc: Fix premature broadcast advertisement by sending node
Prevent a TIPC node from sending out a LINK_STATE message
advertising a broadcast message that it is in the process
of sending, but has not yet actually sent.  Previously, it was
possible for a link timeout to occur in between the time the
broadcast link updated its "last message sent" counter and the
time the broadcast message was passed to the broadcast bearer
for transmission.  This ensures that the code which issues
the LINK_STATE message isn't informed of the new message until
the broadcast bearer has had a chance to send it.

Note: The "last message sent" value is stored in the "fsm_msg_count"
field of the link structure used by the broadcast link.  Since the
broadcast link doesn't utilize the normal link FSM, this field can
be re-used rather than adding a new field to the broadcast link.

Allan Stephens 7e3e5d0950 tipc: Prevent crash when broadcast link cannot send to all nodes
Allow TIPC's broadcast link to continue operation when it is unable
to send a message to all nodes in the cluster.  Previously, the
broadcast link attempted to put the broadcast pseudo-bearer into a
blocked state; however, this caused a crash because the associated
bearer structure is only partially initialized.  Further
investigation has revealed some conceptual problems with blocking
the pseudo-bearer; consequently, this functionality has been
disabled for the time being and the undelivered message is
eventually resent by the broadcast link's existing message
retransmission mechanism (if possible).

Allan Stephens b02b69c8a4 tipc: Check for disabled bearer when processing incoming messages
Add a check to tipc_recv_msg() to ensure it discards messages
arriving on a newly disabled bearer.  This is needed to deal with a
race condition that can arise if the bearer is in the midst of being
disabled when it receives a message.  Performing the check after
tipc_net_lock has been taken ensures that TIPC's bearers are in a
stable state while the message is being processed.
