* ocfs2: fix a tiny race case when firing callbacksJoyce2013-09-111-9/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In o2hb_shutdown_slot() and o2hb_check_slot(), since event is defined as local, it is only valid during the call stack. So the following tiny race case may happen in a multi-volumes mounted environment: o2hb-vol1 o2hb-vol2 1) o2hb_shutdown_slot allocate local event1 2) queue_node_event add event1 to global o2hb_node_events 3) o2hb_shutdown_slot allocate local event2 4) queue_node_event add event2 to global o2hb_node_events 5) o2hb_run_event_list delete event1 from o2hb_node_events 6) o2hb_run_event_list event1 empty, return 7) o2hb_shutdown_slot event1 lifecycle ends 8) o2hb_fire_callbacks event1 is already *invalid* This patch lets it wait on o2hb_callback_sem when another thread is firing callbacks. And for performance consideration, we only call o2hb_run_event_list when there is an event queued.

* ocfs2: fix NULL pointer dereference when traversing o2hb_all_regionsXue jiufei2013-07-031-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There may exist NULL pointer dereference in config_item_name() when one volume (say Volume A) unmounts while another (say Volume B) mounting. Volume A Volume B already Mounted. Unmounting, call o2hb_heartbeat_group_drop_item() -> config_item_put(item) set reg(A)->item.ci_name to NULL in function config_item_cleanup(). begin mounting, call o2hb_region_pin() and tranverse all regions. When reading reg(A)->item.ci_name, it causes NULL pointer dereference. call o2hb_region_release() and del reg(A) from list. So we should skip accessing regions that is going to release when tranverse o2hb_all_regions.

As it is, we have a situation when file_table.c is about handling of struct file and file.c is about handling of descriptor tables; the reasons are historical - file_table.c used to be about a static array of struct file we used to have way back). A lot of stray ends got cleaned up and converted to saner primitives, disgusting mess in android/binder.c is still disgusting, but at least doesn't poke so much in descriptor table guts anymore. A bunch of relatively minor races got fixed in process, plus an ext4 struct file leak. - related thing - fget_light() partially unuglified; see fdget() in there (and yes, it generates the code as good as we used to have). - also related - bits of Cyrill's procfs stuff that got entangled into that work; _not_ all of it, just the initial move to fs/proc/fd.c and switch of fdinfo to seq_file. - Alex's fs/coredump.c spiltoff - the same story, had been easier to take that commit than mess with conflicts. The rest is a separate pile, this was just a mechanical code movement. - a few misc patches all over the place. Not all for this cycle, there'll be more (and quite a few currently sit in akpm's tree)."

* ocfs2/cluster: Increase the live threshold for global heartbeatSunil Mushran2011-05-131-1/+12
| | | | | | | | | | | | | | | | | | | | | | | | We have seen isolated cases (very few, I might add) of o2hb not detecting all live nodes on startup. One plausible reasoning for it is that other node had a hb io delay at the same time. The live threshold set at 2 (as low as it can be) could be increased to ameliorate the situation. But increasing the threshold directly affects mount time. Currently it takes around 5 secs to mount a volume in o2cb cluster with local heartbeat. Increasing the threshold will make mounts even slower. As the issue itself is rare, we have left things as they are for the local heartbeat mode. However we can improve the situation for global heartbeat mode as in that mode, we start the heartbeat much before the mount. This patch doubles the live threshold for the start of the first region in global heartbeat mode. Addresses internal Oracle bug#10635585.
