2009-11-30mac80211: fix spurious delBA handlingJohannes Berg1-1/+9
Lennert Buytenhek noticed that delBA handling in mac80211 was broken and has remotely triggerable problems, some of which are due to some code shuffling I did that ended up changing the order in which things were done -- this was commit d75636ef9c1af224f1097941879d5a8db7cd04e5 Author: Johannes Berg <[email protected]> Date: Tue Feb 10 21:25:53 2009 +0100 mac80211: RX aggregation: clean up stop session and other parts were already present in the original commit d92684e66091c0f0101819619b315b4bb8b5bcc5 Author: Ron Rindjunsky <[email protected]> Date: Mon Jan 28 14:07:22 2008 +0200 mac80211: A-MPDU Tx add delBA from recipient support The first problem is that I moved a BUG_ON before various checks -- thereby making it possible to hit. As the comment indicates, the BUG_ON can be removed since the ampdu_action callback must already exist when the state is != IDLE. The second problem isn't easily exploitable but there's a race condition due to unconditionally setting the state to OPERATIONAL when a delBA frame is received, even when no aggregation session was ever initiated. All the drivers accept stopping the session even then, but that opens a race window where crashes could happen before the driver accepts it. Right now, a WARN_ON may happen with non-HT drivers, while the race opens only for HT drivers. For this case, there are two things necessary to fix it: 1) don't process spurious delBA frames, and be more careful about the session state; don't drop the lock 2) HT drivers need to be prepared to handle a session stop even before the session was really started -- this is true for all drivers (that support aggregation) but iwlwifi which can be fixed easily. The other HT drivers (ath9k and ar9170) are behaving properly already.

2009-11-29ep93xx-eth: check for zero MAC address on probe, not on device openFlorian Fainelli1-9/+3

2009-11-29NET: smc91x: Fix irq flagsRussell King - ARM Linux1-1/+1
smc91x.h defines SMC_IRQ_FLAGS to be -1 when it wants the interrupt flags to be taken from the resource structure. However, d280ead changed this to checking for non-zero resource flags. Unfortunately, this means that on some platforms, we end up passing '-1' to request_irq rather than the desired result. Combine the two conditions into one so that the IRQ flags are taken from the resource if either SMC_IRQ_FLAGS is -1 or the resource flags specify an interrupt trigger. This restores network on at least the Versatile platform. Signed-off-by: Russell King <[email protected]> Acked-by: Eric Miao <[email protected]> Signed-off-by: David S. Miller <[email protected]>

2009-11-29r8169: restore mac addr in rtl8169_remove_one and rtl_shutdownIvan Vecera1-0/+7
The newer chipsets (all PCI-E) are known that they need full power cycle (AC or battery removal) to reset MAC address to a hardwired one. Previous patch to address this problem loads the original MAC address from EEPROM. But it brought other problem for which it is necessary to introduce a new module parameter. However, it might suffice to restore the initial MAC address before shutdown/reboot/kexec and when removing the module. Signed-off-by: Ivan Vecera <[email protected]> Signed-off-by: David S.

2009-11-29PM: fix irq enable/disable in runtime PM codeAlan Stern1-6/+6
This patch (as1305) fixes a bug in the irq-enable settings and removes some related overhead in the runtime PM code. In __pm_runtime_resume(), within the scope of the original spin_lock_irq(), we know that irqs are disabled. There's no reason to go through a pair of enable/disable cycles when acquiring and releasing the parent's lock. In __pm_runtime_set_status(), irqs are already disabled when the parent's lock is acquired, and they must remain disabled when it is released.

2009-11-28pcmcia: rework the irq_req_t typedefDominik Brodowski51-124/+49
Most of the irq_req_t typedef'd struct can be re-worked quite easily: (1) IRQInfo2 was unused in any case, so drop it. (2) IRQInfo1 was used write-only, so drop it. (3) Instance (private data to be passed to the IRQ handler): Most PCMCIA drivers using pcmcia_request_irq() to actually register an IRQ handler set the "dev_id" to the same pointer as the "priv" pointer in struct pcmcia_device. Modify the two exceptions (ipwireless, ibmtr_cs) to also work this waym and set the IRQ handler's "dev_id" to p_dev->priv unconditionally. (4) Handler is to be of type irq_handler_t. (5) Handler != NULL already tells whether an IRQ handler is present. Therefore, we do not need the IRQ_HANDLER_PRESENT flag in irq_req_t.Attributes.

2009-11-28pcmcia: Change window_handle_t logic to unsigned longMagnus Damm4-34/+35
Logic changes based on top of the other patches: This set of patches changed window_handle_t from being a pointer to an unsigned long. The unsigned long is now a simple index into socket->win[]. Going from a pointer to unsigned long should leave the user space interface unchanged unless I'm mistaken. This change results in code that is less error prone and a user space interface which is much cleaner and safer. A nice side effect is that we are also are able to remove all members except one from window_t. [ [email protected]: Update to 2.6.31. Also, a plain "index" to socket->win[] does not work, as several codepaths rely on "window_handle_t" being non-zero if used. Therefore, set the window_handle_t to the socket->win[] index + 1. ] CC: [email protected] Signed-off-by: Magnus Damm <[email protected]> Signed-off-by: Dominik Brodowski <[email protected]>

2009-11-26[SCSI] fix crash when disconnecting usb storageAlexey Kuznetsov1-1/+1
__scsi_remove_device() in scsi_forget_host() is executed out of scan_mutex and races with scsi_destroy_sdev() <- scsi_sysfs_add_devices() <- scsi_finish_async_scan(). The result is use after free and/or double free, oops. The fix is simple, move scsi_forget_host() under scan_mutex. scsi_forget_host() is just sequence of __scsi_remove_device(). All another calls of __scsi_remove_device() are made under scan_mutex. So that it is safe. Signed-off-by: Alexey Kuznetsov <[email protected]> Signed-off-by: Denis V.

2009-11-26[SCSI] fix async scan add/remove race resulting in an oopsJames Bottomley2-50/+31
Async scanning introduced a very wide window where the SCSI device is up and running but has not yet been added to sysfs. We delay the adding until all scans have completed to retain the same ordering as sync scanning. This delay in visibility causes an oops if a device is removed before we make it visible because the SCSI removal routines have an inbuilt assumption that if a device is in SDEV_RUNNING state, it must be visible (which is not necessarily true in the async scanning case). Fix this by introducing an additional is_visible flag which we can use to condition the tear down so we do the right thing for running but not yet made visible.
