2010-05-11PCI: aerdrv: introduce default_downstream_reset_linkHidetoshi Seto4-46/+71
I noticed that when I inject a fatal error to an endpoint via aer-inject, aer_root_reset() is called as reset_link for a downstream port at upstream of the endpoint: pcieport 0000:00:06.0: AER: Uncorrected (Fatal) error received: id=5401 : pcieport 0000:52:02.0: Root Port link has been reset It externally appears to be working, but internally issues some accesses to PCI_ERR_ROOT_COMMAND/STATUS registers that is for root port so not available on downstream port. This patch introduces default_downstream_reset_link that is a version of aer_root_reset() with no accesses to root port's register. It is used for downstream ports that has no reset_link function its specific. This patch also updates related description in pcieaer-howto.txt. Some minor fixes are included.

2010-05-11PCI: aerdrv: remove is_downstreamHidetoshi Seto1-21/+12
The pcie->port of port service device points the port associated the service with. The find_aer_service iterates over children of given port udev. So it is clear that the pcie->port of port service of given port udev must always point the udev. Therefore we can know the type of udev without checking its children.

2010-05-11PCI: aerdrv: rework get_e_source()Hidetoshi Seto1-32/+31
Current get_e_source() returns pointer to an element of array. However since it also progress consume counter, it is possible that the element is overwritten by newly produced data before the element is really consumed. This patch changes get_e_source() to copy contents of the element to address pointed by its caller. Once copied the element in array can be consumed. And relocate this function to more innocuous place.

This cleanup solves some minor naming issues by removing unuseful function aer_delete_rootport() and by renaming disable_root_aer() to aer_disable_rootport(). - Inconsistent location of alloc & free: The struct rpc is allocated in aer_alloc_rpc() at aerdrv.c while it is implicitly freed in aer_delete_rootport() at aerdrv_core.c. - Inconsistent function name: It makes a bit confusion that aer_delete_rootport() is seemed to be paired with aer_enable_rootport(), i.e. there is neither "add" against "delete" nor "disable" against "enable".

2010-05-11resource: shared I/O region supportAlan Cox2-2/+18
SuperIO devices share regions and use lock/unlock operations to chip select. We therefore need to be able to request a resource and wait for it to be freed by whichever other SuperIO device currently hogs it. Right now you have to poll which is horrible. Add a MUXED field to IO port resources. If the MUXED field is set on the resource and on the request (via request_muxed_region) then we block until the previous owner of the muxed resource releases their region. This allows us to implement proper resource sharing and locking for superio chips using code of the form enable_my_superio_dev() { request_muxed_region(0x44, 0x02, "superio:watchdog"); outb() ..sequence to enable chip } disable_my_superio_dev() { outb() .. sequence of disable chip release_region(0x44, 0x02); } Signed-off-by: Giel van Schijndel <me@mortis.eu> Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>

2010-05-11CacheFiles: Fix occasional EIO on call to vfs_unlink()David Howells2-12/+87
Fix an occasional EIO returned by a call to vfs_unlink(): [ 4868.465413] CacheFiles: I/O Error: Unlink failed [ 4868.465444] FS-Cache: Cache cachefiles stopped due to I/O error [ 4947.320011] CacheFiles: File cache on md3 unregistering [ 4947.320041] FS-Cache: Withdrawing cache "mycache" [ 5127.348683] FS-Cache: Cache "mycache" added (type cachefiles) [ 5127.348716] CacheFiles: File cache on md3 registered [ 7076.871081] CacheFiles: I/O Error: Unlink failed [ 7076.871130] FS-Cache: Cache cachefiles stopped due to I/O error [ 7116.780891] CacheFiles: File cache on md3 unregistering [ 7116.780937] FS-Cache: Withdrawing cache "mycache" [ 7296.813394] FS-Cache: Cache "mycache" added (type cachefiles) [ 7296.813432] CacheFiles: File cache on md3 registered What happens is this: (1) A cached NFS file is seen to have become out of date, so NFS retires the object and immediately acquires a new object with the same key. (2) Retirement of the old object is done asynchronously - so the lookup/create to generate the new object may be done first. This can be a problem as the old object and the new object must exist at the same point in the backing filesystem (i.e. they must have the same pathname). (3) The lookup for the new object sees that a backing file already exists, checks to see whether it is valid and sees that it isn't. It then deletes that file and creates a new one on disk. (4) The retirement phase for the old file is then performed. It tries to delete the dentry it has, but ext4_unlink() returns -EIO because the inode attached to that dentry no longer matches the inode number associated with the filename in the parent directory. The trace below shows this quite well.

NFS says that the auxiliary data indicate the file is out of date (obvious to us - that's why NFS ditched the old version and got a new one). CacheFiles then deletes the old file (dentry ffff8800369faac8). [kslowd] redo lookup [kslowd] lookup 'Es0g00og0_Nd_XCYe3BOzvXrsBLMlN6aw16M1htaA' [kslowd] next -> ffff88002cd94288 negative [kslowd] create -> ffff88002cd94288{ffff88002cdaf238{ino=148247}} CacheFiles then redoes the lookup and gets a negative result in a new dentry (ffff88002cd94288) which it then creates a file for. [kslowd] ==> cachefiles_mark_object_active(,OBJ53) [kslowd] <== cachefiles_mark_object_active() = 0 [kslowd] === OBTAINED_OBJECT === [kslowd] <== cachefiles_walk_to_object() = 0 [148247] [kslowd] <== fscache_object_state_machine() [->OBJECT_AVAILABLE] The new object is then marked active and the state machine moves to the available state - at which point NFS can start filling the object.

2010-05-10IPv4: unresolved multicast route cleanupAndreas Meissner1-1/+2
Fixes the expiration timer for unresolved multicast route entries. In case new multicast routing requests come in faster than the expiration timeout occurs (e.g. zap through multicast TV streams), the timer is prevented from being called at time for already existing entries. As the single timer is resetted to default whenever a new entry is made, the timeout for existing unresolved entires are missed and/or not updated. As a consequence new requests are denied when the limit of unresolved entries has been reached because old entries live longer than they are supposed to. The solution is to reset the timer only for the first unresolved entry in the multicast routing cache. All other timers are already set and updated correctly within the timer function itself by now.

2010-05-09cpuidle: Fix incorrect optimizationArjan van de Ven1-5/+4
commit 672917dcc78 ("cpuidle: menu governor: reduce latency on exit") added an optimization, where the analysis on the past idle period moved from the end of idle, to the beginning of the new idle. Unfortunately, this optimization had a bug where it zeroed one key variable for new use, that is needed for the analysis. The fix is simple, zero the variable after doing the work from the previous idle. During the audit of the code that found this issue, another issue was also found; the ->measured_us data structure member is never set, a local variable is always used instead.

2010-05-07HID: fix suspend crash by moving initializations earlierAlan Stern1-7/+6
Although the usbhid driver allocates its usbhid structure in the probe routine, several critical fields in that structure don't get initialized until usbhid_start(). However if report descriptor parsing fails then usbhid_start() is never called. This leads to problems during system suspend -- the system will freeze. This patch (as1378) fixes the bug by moving the initialization statements up into usbhid_probe().

Then we start that process, but the AP doesn't respond. While we're still waiting for an AP response, userspace asks for a deauth. We do the deauth, but don't abort the association work. Then once the association work times out we tell cfg80211, but it no longer wants to know since for all it is concerned we accepted the deauth that also kills the association attempt. Fix this by, upon receipt of deauth request, removing the association work and continuing to send the deauth. Unfortunately the user reporting the issue is not able to reproduce this problem anymore and cannot verify this fix. This seems like a well understood issue though and I thus present the patch.
