2009-08-09perf_counter: Fix/complete ftrace event records samplingFrederic Weisbecker
This patch implements the kernel side support for ftrace event record sampling. A new counter sampling attribute is added: PERF_SAMPLE_TP_RECORD which requests ftrace events record sampling. In this case if a PERF_TYPE_TRACEPOINT counter is active and a tracepoint fires, we emit the tracepoint binary record to the perfcounter event buffer, as a sample. Result, after setting PERF_SAMPLE_TP_RECORD attribute from perf record: perf record -f -F 1 -a -e workqueue:workqueue_execution perf report -D 0x21e18 [0x48]: event: 9 . . ... raw event: size 72 bytes . 0000: 09 00 00 00 01 00 48 00 d0 c7 00 81 ff ff ff ff ......H........ . 0010: 0a 00 00 00 0a 00 00 00 21 00 00 00 00 00 00 00 ........!...... . 0020: 2b 00 01 02 0a 00 00 00 0a 00 00 00 65 76 65 6e +...........eve . 0030: 74 73 2f 31 00 00 00 00 00 00 00 00 0a 00 00 00 ts/1........... . 0040: e0 b1 31 81 ff ff ff ff ....... . 0x21e18 [0x48]: PERF_EVENT_SAMPLE (IP, 1): 10: 0xffffffff8100c7d0 period: 33 The raw ftrace binary record starts at offset 0020.

For that we need to have an instant access to the perf counter attribute. This is a matter of a flag to add in the struct ftrace_event. - Take care of the events recursivity! Don't ever try to record a lock event for example, it seems some locking is used in the profiling fast path and lead to a tracing recursivity. That will be fixed using raw spinlock or recursivity protection. - [...] - Profit! :-) Signed-off-by: Frederic Weisbecker <fweisbec@gmail.com> Cc: Li Zefan <lizf@cn.fujitsu.com> Cc: Tom Zanussi <tzanussi@gmail.com> Cc: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Cc: Mike Galbraith <efault@gmx.de> Cc: Steven Rostedt <rostedt@goodmis.org> Cc: Paul Mackerras <paulus@samba.org> Cc: Pekka Enberg <penberg@cs.helsinki.fi> Cc: Gabriel Munteanu <eduard.munteanu@linux360.ro> Cc: Lai Jiangshan <laijs@cn.fujitsu.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>

2009-08-07mm: make set_mempolicy(MPOL_INTERLEAV) N_HIGH_MEMORY awareKAMEZAWA Hiroyuki
At first, init_task's mems_allowed is initialized as this. init_task->mems_allowed == node_state[N_POSSIBLE] And cpuset's top_cpuset mask is initialized as this top_cpuset->mems_allowed = node_state[N_HIGH_MEMORY] Before 2.6.29: policy's mems_allowed is initialized as this. 1. update tasks->mems_allowed by its cpuset->mems_allowed. 2. policy->mems_allowed = nodes_and(tasks->mems_allowed, user's mask) Updating task's mems_allowed in reference to top_cpuset's one. cpuset's mems_allowed is aware of N_HIGH_MEMORY, always. In 2.6.30: After commit 58568d2a8215cb6f55caf2332017d7bdff954e1c ("cpuset,mm: update tasks' mems_allowed in time"), policy's mems_allowed is initialized as this. 1. policy->mems_allowd = nodes_and(task->mems_allowed, user's mask) Here, if task is in top_cpuset, task->mems_allowed is not updated from init's one. Assume user excutes command as #numactrl --interleave=all ,.... policy->mems_allowd = nodes_and(N_POSSIBLE, ALL_SET_MASK) Then, policy's mems_allowd can includes a possible node, which has no pgdat. MPOL's INTERLEAVE just scans nodemask of task->mems_allowd and access this directly. NODE_DATA(nid)->zonelist even if NODE_DATA(nid)==NULL Then, what's we need is making policy->mems_allowed be aware of N_HIGH_MEMORY. This patch does that. But to do so, extra nodemask will be on statck. Because I know cpumask has a new interface of CPUMASK_ALLOC(), I added it to node. This patch stands on old behavior. But I feel this fix itself is just a Band-Aid. But to do fundametal fix, we have to take care of memory hotplug and it takes time. (task->mems_allowd should be N_HIGH_MEMORY, I think.) mpol_set_nodemask() should be aware of N_HIGH_MEMORY and policy's nodemask should be includes only online nodes. In old behavior, this is guaranteed by frequent reference to cpuset's code. Now, most of them are removed and mempolicy has to check it by itself. To do check, a few nodemask_t will be used for calculating nodemask. But, size of nodemask_t can be big and it's not good to allocate them on stack. Now, cpumask_t has CPUMASK_ALLOC/FREE an easy code for get scratch area. NODEMASK_ALLOC/FREE shoudl be there.

2009-08-07vfs: add __destroy_inodeChristoph Hellwig
When we want to tear down an inode that lost the add to the cache race in XFS we must not call into ->destroy_inode because that would delete the inode that won the race from the inode cache radix tree. This patch provides the __destroy_inode helper needed to fix this, the actual fix will be in th next patch. As XFS was the only reason destroy_inode was exported we shift the export to the new __destroy_inode. Signed-off-by: Christoph Hellwig <hch@lst.de> Reviewed-by: Eric Sandeen <sandeen@sandeen.net>
2009-08-07vfs: fix inode_init_always calling conventionChristoph Hellwig
Currently inode_init_always calls into ->destroy_inode if the additional initialization fails. That's not only counter-intuitive because inode_init_always did not allocate the inode structure, but in case of XFS it's actively harmful as ->destroy_inode might delete the inode from a radix-tree that has never been added. This in turn might end up deleting the inode for the same inum that has been instanciated by another process and cause lots of cause subtile problems. Also in the case of re-initializing a reclaimable inode in XFS it would free an inode we still want to keep alive.

2009-08-06net: Avoid enqueuing skb for default qdiscsKrishna Kumar
dev_queue_xmit enqueue's a skb and calls qdisc_run which dequeue's the skb and xmits it. In most cases, the skb that is enqueue'd is the same one that is dequeue'd (unless the queue gets stopped or multiple cpu's write to the same queue and ends in a race with qdisc_run). For default qdiscs, we can remove the redundant enqueue/dequeue and simply xmit the skb since the default qdisc is work-conserving. The patch uses a new flag - TCQ_F_CAN_BYPASS to identify the default fast queue. The controversial part of the patch is incrementing qlen when a skb is requeued - this is to avoid checks like the second line below: + } else if ((q->flags & TCQ_F_CAN_BYPASS) && !qdisc_qlen(q) && >> !q->gso_skb && + !test_and_set_bit(__QDISC_STATE_RUNNING, &q->state)) { Results of a 2 hour testing for multiple netperf sessions (1, 2, 4, 8, 12 sessions on a 4 cpu system-X).

2009-08-04tty-ldisc: make refcount be atomic_t 'users' countLinus Torvalds
This is pure preparation of changing the ldisc reference counting to be a true refcount that defines the lifetime of the ldisc. But this is a purely syntactic change for now to make the next steps easier. This patch should make no semantic changes at all. But I wanted to make the ldisc refcount be an atomic (I will be touching it without locks soon enough), and I wanted to rename it so that there isn't quite as much confusion between 'ldo->refcount' (ldisk operations refcount) and 'ld->refcount' (ldisc refcount itself) in the same file. So it's now an atomic 'ld->users' count. It still starts at zero, despite having a reference from 'tty->ldisc', but that will change once we turn it into a _real_ refcount.

2009-08-04mac80211: FIF_PSPOLL filter flagIgor Perminov
When an interface is configured in the AP mode, the mac80211 implementation doesn't inform the driver to receive PS Poll frames. It leads to inability to communicate with power-saving stations reliably. The FIF_CONTROL flag isn't passed by mac80211 to ieee80211_ops.configure_filter when an interface is in the AP mode. And it's ok, because we don't want to receive ACK frames and other control ones, but only PS Poll ones. This patch introduces the FIF_PSPOLL filter flag in addition to FIF_CONTROL, which means for the driver "pass PS Poll frames". This flag is passed to the driver: A) When an interface is configured in the AP mode. B) In all cases, when the FIF_CONTROL flag was passed earlier (in addition to it).

2009-08-04mac80211: redefine usage of the mac80211 workqueueLuis R. Rodriguez
The mac80211 workqueue exists to enable mac80211 and drivers to queue their own work on a single threaded workqueue. mac80211 takes care to flush the workqueue during suspend but we never really had requirements on drivers for how they should use the workqueue in consideration for suspend. We extend mac80211 to document how the mac80211 workqueue should be used, how it should not be used and finally move raw access to the workqueue to mac80211 only. Drivers and mac80211 use helpers to queue work onto the mac80211 workqueue: * ieee80211_queue_work() * ieee80211_queue_delayed_work() These helpers will now warn if mac80211 already completed its suspend cycle and someone is trying to queue work. mac80211 flushes the mac80211 workqueue prior to suspend a few times, but we haven't taken the care to ensure drivers won't add more work after suspend. To help with this we add a warning when someone tries to add work and mac80211 already completed the suspend cycle. Drivers should ensure they cancel any work or delayed work in the mac80211 stop() callback. Signed-off-by: Luis R. Rodriguez <lrodriguez@atheros.com> Signed-off-by: John W.

2009-08-03cfg80211: fix regression on beacon world roaming featureLuis R. Rodriguez
A regression was added through patch a4ed90d6: "cfg80211: respect API on orig_flags on channel for beacon hint" We did indeed respect _orig flags but the intention was not clearly stated in the commit log. This patch fixes firmware issues picked up by iwlwifi when we lift passive scan of beaconing restrictions on channels its EEPROM has been configured to always enable. By doing so though we also disallowed beacon hints on devices registering their wiphy with custom world regulatory domains enabled, this happens to be currently ath5k, ath9k and ar9170. The passive scan and beacon restrictions on those devices would never be lifted even if we did find a beacon and the hardware did support such enhancements when world roaming. Since Johannes indicates iwlwifi firmware cannot be changed to allow beacon hinting we set up a flag now to specifically allow drivers to disable beacon hints for devices which cannot use them. We enable the flag on iwlwifi to disable beacon hints and by default enable it for all other drivers. It should be noted beacon hints lift passive scan flags and beacon restrictions when we receive a beacon from an AP on any 5 GHz non-DFS channels, and channels 12-14 on the 2.4 GHz band. We don't bother with channels 1-11 as those channels are allowed world wide. This should fix world roaming for ath5k, ath9k and ar9170, thereby improving scan time when we receive the first beacon from any AP, and also enabling beaconing operation (AP/IBSS/Mesh) on cards which would otherwise not be allowed to do so. Drivers not using custom regulatory stuff (wiphy_apply_custom_regulatory()) were not affected by this as the orig_flags for the channels would have been cleared upon wiphy registration. I tested this with a world roaming ath5k card. Cc: Jouni Malinen <jouni.malinen@atheros.com> Signed-off-by: Luis R.

2009-08-03bluetooth: rfcomm_init bug fixDave Young
rfcomm tty may be used before rfcomm_tty_driver initilized, The problem is that now socket layer init before tty layer, if userspace program do socket callback right here then oops will happen. reporting in: http://marc.info/?l=linux-bluetooth&m=124404919324542&w=2 make 3 changes: 1. remove #ifdef in rfcomm/core.c, make it blank function when rfcomm tty not selected in rfcomm.h 2. tune the rfcomm_init error patch to ensure tty driver initilized before rfcomm socket usage. 3. remove __exit for rfcomm_cleanup_sockets because above change need call it in a __init function.

The patch fixes a bug when converting dev to mtd_info by using the drvdata of the dev, the previous code used container_of(dev, struct mtd_info, dev), but won't work for the mtdXro devices as they created without being contained inside mtd_info structure.

2009-08-02neigh: Convert garbage collection from softirq to workqueueEric Dumazet
Current neigh_periodic_timer() function is fired by timer IRQ, and scans one hash bucket each round (very litle work in fact) As we are supposed to scan whole hash table in 15 seconds, this means neigh_periodic_timer() can be fired very often. (depending on the number of concurrent hash entries we stored in this table) Converting this to a workqueue permits scanning whole table, minimizing icache pollution, and firing this work every 15 seconds, independantly of hash table size. This 15 seconds delay is not a hard number, as work is a deferrable one. Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
