* mac80211: cancel restart_work in ieee80211_unregister_hwChristian Lamparter2010-08-25
| | | | | | | | | | | | | | | | | Unlike most other workqueue-tasks, the restart_work is not scheduled onto mac80211's private per-interface workqueue, but onto one of the system-wide workqueues. Therefore the mac80211-stack has to cancel any pending restarts, before destroying the shared device context and handing back the memory. Otherwise - under very unlucky circumstances - there could be a stale work- item left, because some other kernel component might have delayed the execution of ieee80211_restart_work for too long.

* cfg80211/mac80211: extensible frame processingJohannes Berg2010-08-24
| | | | | | | | | | | | | | | Allow userspace to register for more than just action frames by giving the frame subtype, and make it possible to use this in various modes as well. With some tweaks and some added functionality this will, in the future, also be usable in AP mode and be able to replace the cooked monitor interface currently used in that case.

* mac80211: remove unused don't-encrypt flagJohannes Berg2010-08-24
| | | | | | | | | | | | | When MFP is disabled, action frames will not be encrypted since they are management frames and the only management frames that can then be encrypted are authentication frames.

| | | | | | | | | | | | | | | | This function analyses only its single, value-passed argument, and has no side effects. Thus it can be const, which makes mac80211 smaller, for example: text data bss dec hex filename 362518 16720 884 380122 5ccda mac80211.ko (before) 362358 16720 884 379962 5cc3a mac80211.ko (after) a 160 byte saving in text size, and an optimisation because the function won't be called as often.

| | | | | | | | | | | | | Currently, mac80211 translates the cfg80211 cipher suite selectors into ALG_* values.

* mac80211: AMPDU rx reorder timeout timerChristian Lamparter2010-08-16
| | | | | | | | | | | | | | | | | | | | | This patch introduces a new timer, which will release queued-up MPDUs from the reorder buffer, whenever they've waited for more than HT_RX_REORDER_BUF_TIMEOUT (which is at around 100 ms). The advantage of having a dedicated timer, instead of relying on a constant stream of freshly arriving aMPDUs to release the old ones, is particularly observable when even a small fraction of MPDUs are forever lost at low network speeds. Previously under these circumstances frames would become stuck in the reorder buffer and the network stack of both HT peers throttled back, instead of revving up and gunning the pipes.

| | | | | | | | | | | | When running in client mode and associating to an AP, the channel change is usually performed with the offchannel flag still set. However after the assoc is complete, the following channel change event is suppressed because the run time channel is already set to the operating channel. Fix this by sending channel change notifications to the driver even if only the offchannel flag changes. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W.

| | * Bluetooth: Fix incorrect setting of remote_tx_win for L2CAP ERTMMat Martineau2010-08-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | remote_tx_win is intended to be set on receipt of an L2CAP configuration request. The value is used to determine the size of the transmit window on the remote side of an ERTM connection, so L2CAP can stop sending frames when that remote window is full. An incorrect remote_tx_win value will cause the stack to not fully utilize the tx window (performance impact), or to overfill the remote tx window (causing dropped frames or a disconnect). This patch removes an extra setting of remote_tx_win when a configuration response is received. The transmit window has a different meaning in a response - it is an informational value less than or equal to the local tx_win.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Incoming configuration values must be converted to native CPU order before use. This fixes a bug where a little-endian MPS value is compared to a native CPU value. On big-endian processors, this can cause ERTM and streaming mode segmentation to produce PDUs that are larger than the remote stack is expecting, or that would produce fragmented skbs that the current FCS code cannot handle.

However, its caller (call_timer_fn()) has an apparent lock on the timer struct. The problem is that rxrpc_resend_time_expired() isn't permitted to lock call->state_lock as this could cause a deadlock against rxrpc_send_abort() as that takes state_lock and then attempts to delete the resend timer by calling del_timer_sync(). The deadlock can occur because del_timer_sync() will sit there forever waiting for rxrpc_resend_time_expired() to return, but the latter may then wait for call->state_lock, which rxrpc_send_abort() holds around del_timer_sync()... This leads to a warning appearing in the kernel log that looks something like the attached. It should be sufficient to simply dispense with the locks. It doesn't matter if we set the resend timer expired event bit and queue the event processor whilst we're changing state to one where the resend timer is irrelevant as the event can just be ignored by the processor thereafter. ======================================================= [ INFO: possible circular locking dependency detected ] 2.6.35-rc3-cachefs+ #115 ------------------------------------------------------- swapper/0 is trying to acquire lock: (&call->state_lock){++--..}, at: [<ffffffffa00200d4>] rxrpc_resend_time_expired+0x56/0x96 [af_rxrpc] but task is already holding lock: (&call->resend_timer){+.-...}, at: [<ffffffff8103b675>] run_timer_softirq+0x182/0x2a5 which lock already depends on the new lock. the existing dependency chain (in reverse order) is: -> #1 (&call->resend_timer){+.-...}: [<ffffffff810560bc>] __lock_acquire+0x889/0x8fa [<ffffffff81056184>] lock_acquire+0x57/0x6d [<ffffffff8103bb9c>] del_timer_sync+0x3c/0x86 [<ffffffffa002bb7a>] rxrpc_send_abort+0x50/0x97 [af_rxrpc] [<ffffffffa002bdd9>] rxrpc_kernel_abort_call+0xa1/0xdd [af_rxrpc] [<ffffffffa0061588>] afs_deliver_to_call+0x129/0x368 [kafs] [<ffffffffa006181b>] afs_process_async_call+0x54/0xff [kafs] [<ffffffff8104261d>] worker_thread+0x1ef/0x2e2 [<ffffffff81045f47>] kthread+0x7a/0x82 [<ffffffff81002cd4>] kernel_thread_helper+0x4/0x10 -> #0 (&call->state_lock){++--..}: [<ffffffff81055237>] validate_chain+0x727/0xd23 [<ffffffff810560bc>] __lock_acquire+0x889/0x8fa [<ffffffff81056184>] lock_acquire+0x57/0x6d [<ffffffff813e6b69>] _raw_read_lock_bh+0x34/0x43 [<ffffffffa00200d4>] rxrpc_resend_time_expired+0x56/0x96 [af_rxrpc] [<ffffffff8103b6e6>] run_timer_softirq+0x1f3/0x2a5 [<ffffffff81036828>] __do_softirq+0xa2/0x13e [<ffffffff81002dcc>] call_softirq+0x1c/0x28 [<ffffffff810049f0>] do_softirq+0x38/0x80 [<ffffffff810361a2>] irq_exit+0x45/0x47 [<ffffffff81018fb3>] smp_apic_timer_interrupt+0x88/0x96 [<ffffffff81002893>] apic_timer_interrupt+0x13/0x20 [<ffffffff810011ac>] cpu_idle+0x4d/0x83 [<ffffffff813e06f3>] start_secondary+0x1bd/0x1c1 other info that might help us debug this: 1 lock held by swapper/0: #0: (&call->resend_timer){+.-...}, at: [<ffffffff8103b675>] run_timer_softirq+0x182/0x2a5 stack backtrace: Pid: 0, comm: swapper Not tainted 2.6.35-rc3-cachefs+ #115 Call Trace: <IRQ> [<ffffffff81054414>] print_circular_bug+0xae/0xbd [<ffffffff81055237>] validate_chain+0x727/0xd23 [<ffffffff810560bc>] __lock_acquire+0x889/0x8fa [<ffffffff810539a7>] ? mark_lock+0x42f/0x51f [<ffffffff81056184>] lock_acquire+0x57/0x6d [<ffffffffa00200d4>] ? rxrpc_resend_time_expired+0x56/0x96 [af_rxrpc] [<ffffffff813e6b69>] _raw_read_lock_bh+0x34/0x43 [<ffffffffa00200d4>] ? rxrpc_resend_time_expired+0x56/0x96 [af_rxrpc] [<ffffffffa00200d4>] rxrpc_resend_time_expired+0x56/0x96 [af_rxrpc] [<ffffffff8103b6e6>] run_timer_softirq+0x1f3/0x2a5 [<ffffffff8103b675>] ? run_timer_softirq+0x182/0x2a5 [<ffffffffa002007e>] ? rxrpc_resend_time_expired+0x0/0x96 [af_rxrpc] [<ffffffff810367ef>] ? __do_softirq+0x69/0x13e [<ffffffff81036828>] __do_softirq+0xa2/0x13e [<ffffffff81002dcc>] call_softirq+0x1c/0x28 [<ffffffff810049f0>] do_softirq+0x38/0x80 [<ffffffff810361a2>] irq_exit+0x45/0x47 [<ffffffff81018fb3>] smp_apic_timer_interrupt+0x88/0x96 [<ffffffff81002893>] apic_timer_interrupt+0x13/0x20 <EOI> [<ffffffff81049de1>] ? __atomic_notifier_call_chain+0x0/0x86 [<ffffffff8100955b>] ? mwait_idle+0x6e/0x78 [<ffffffff81009552>] ? mwait_idle+0x65/0x78 [<ffffffff810011ac>] cpu_idle+0x4d/0x83 [<ffffffff813e06f3>] start_secondary+0x1bd/0x1c1 Signed-off-by: David Howells <dhowells@redhat.com> Signed-off-by: David S.

" So even if remove fails we need to destroy the fid. Without this patch an rmdir on a directory with contents leave the new cloned directory fid fid attached to fidlist. On umount we dump the fids on the fidlist ~# rmdir /mnt2/test4/ rmdir: failed to remove `/mnt2/test4/': Directory not empty ~# umount /mnt2/ ~# dmesg [ 228.474323] Found fid 3 not clunked Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com> Signed-off-by: Venkateswararao Jujjuri <jvrao@linux.vnet.ibm.com> Signed-off-by: Eric Van Hensbergen <ericvh@gmail.com>

This fid can later be used to set the xattr value. flag value is derived from set Linux setxattr. The manpage says "The flags parameter can be used to refine the semantics of the operation. XATTR_CREATE specifies a pure create, which fails if the named attribute exists already. XATTR_REPLACE specifies a pure replace operation, which fails if the named attribute does not already exist. By default (no flags), the extended attribute will be created if need be, or will simply replace the value if the attribute exists." The actual setxattr operation happens when the fid is clunked. At that point the written byte count and the attr_size specified in TXATTRCREATE should be same otherwise an error will be returned.

The mode argument specifies the permissions to use. New file is created with the uid if the fid and with supplied gid. The flags argument represent Linux access mode flags with which the caller is requesting to open the file with. Protocol allows all the Linux access modes but it is upto the server to allow/disallow any of these acess modes. If the server doesn't support any of the access mode, it is expected to return error.
