* tipc: Prevent null pointer error when removing a node subscriptionAllan Stephens2011-03-132-8/+10
| | | | | | | | | | | | | | | | | Prevents a null pointer dereference from occurring if a node subscription is triggered at the same time that the subscribing port or publication is terminating the subscription. The problem arises if the triggering routine asynchronously activates and deregisters the node subscription while deregistration is already underway -- the deregistration routine may find that the pointer it has just verified to be non-NULL is now NULL. To avoid this race condition the triggering routine now simply marks the node subscription as defunct (to prevent it from re-activating) instead of deregistering it. The subscription is now both deregistered and destroyed only when the subscribing port or publication code terminates the node subscription.

* tipc: Add network address mask helper routinesAllan Stephens2011-03-133-7/+16
| | | | | | | | | | | | Introduces a pair of helper routines that convert the network address for a TIPC node into the network address for its cluster or zone. This is a cosmetic change designed to avoid future errors caused by the incorrect use of address bitmasks, and does not alter the existing operation of TIPC.

* tipc: Correct broadcast link peer info when displaying linksAllan Stephens2011-03-131-1/+1
| | | | | | | | | | | Fixes a typo in the calculation of the network address of a node's own cluster when generating a response to the configuration command that lists all of the node's links. The correct mask value for a <Z.C.N> network address uses 1's for the 8-bit zone and 12-bit cluster parts and 0's for the 12-bit node part.

* tipc: Allow receiving into iovec containing multiple entriesAllan Stephens2011-03-131-23/+15
| | | | | | | | | | | | Enhances TIPC's socket receive routines to support iovec structures containing more than a single entry. This change leverages existing sk_buff routines to do most of the work; the only significant change to TIPC itself is that an sk_buff now records how much data has been already consumed as an numeric offset, rather than as a pointer to the first unread data byte.

| | | | | | | | | | | Now we have struct flowi4, flowi6, and flowidn for each address family. And struct flowi is just a union of them all. It might have been troublesome to convert flow_cache_uli_match() but as it turns out this function is completely unused and therefore can be simply removed. Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Regulatory devices issue change uevents to inform userspace of a need to call the crda tool; however these can often be sent before udevd is running, and were not previously included in the results of udevadm trigger (which requests a new change event using the /uevent attribute of the sysfs object). Add a uevent function to the device type which includes the COUNTRY information from the last request if it has yet to be processed, the case of multiple requests is already handled in the code by checking whether an unprocessed one is queued in the same manner and refusing to queue a new one. The existing udev rule continues to work as before.
