From 0f4bd46ec252887f44f1f065b41867cac8f70dfb Mon Sep 17 00:00:00 2001 From: KOSAKI Motohiro Date: Tue, 22 Dec 2009 03:15:43 +0000 Subject: kmsg_dump: Dump on crash_kexec as well crash_kexec gets called before kmsg_dump(KMSG_DUMP_OOPS) if panic_on_oops is set, so the kernel log buffer is not stored for this case. This patch adds a KMSG_DUMP_KEXEC dump type which gets called when crash_kexec() is invoked. To avoid getting double dumps, the old KMSG_DUMP_PANIC is moved below crash_kexec(). The mtdoops driver is modified to handle KMSG_DUMP_KEXEC in the same way as a panic.

This patch fixes this behaviour. Tested only with the Intel i915 driver on an Intel GM45 Express chipset.

This should avoid a race condition on nv0x, if we're doing it with actual PGRAPH objects and a there's a fence within the FIFO DMA fetch area when a context switch kicks in. In that case we get an ILLEGAL_MTHD interrupt as expected, but the values in PGRAPH_TRAPPED_ADDR aren't calculated correctly and they're almost useless (e.g. you can see ILLEGAL_MTHDs for the now inactive channel, with a wrong offset/data pair).

NVIDIA? :P It appears it's possible for a ctxprog to run even while a GPU exception is pending. The GF8 and up ctxprogs appear to have a small snippet of code which detects this, and stalls the ctxprog until it's been handled, which essentially looks like: if (r2 & 0x00008000) { r0 |= 0x80000000; while (r0 & 0x80000000) {} } I don't know of any way that flag would get cleared unless the driver intervenes (and indeed, in the cases I've seen the hang, nothing steps in to automagically clear it for us). This patch causes the driver to clear the flag during the PGRAPH IRQ handler.

While doing so, it destroys the operation fence, causing nouveau_fence_emit to crash. This patch fixes this bug by taking the fence object out of validate_op and creating it just before emit. The fence pointer is initialized to 0 and unref'ed unconditionally. In addition to fixing the bug, this prevents its reintroduction and simplifies the code.

This was more than likely because of incorrect parsing of previous opcodes, and I hardly think aborting a script half way through is going to be any better (in fact, we have had bug reports where this has been the cause of s/r failures among other things). This patch (which has been in Fedora 12 for a long time now) removes all checking for known register ranges, and just leaves the check to ensure the access is within the mapped aperture to avoid an oops.

Cisco reported on RHEL4 U6 and SAP reported on SLES9 SP4 and SLES10 SP2. We added these fixes on RHEL4 U6 and gave a private build to IBM and Cisco. Cisco and IBM tested it for more than 15 days and they reported that they did not see the issue so far. Before the fix, Cisco used to see the issue within 5 days. We generated a patch for SLES9 SP4 and SLES10 SP2 and submitted to Novell. Novell applied the patch and gave a test build to SAP. SAP tested and reported that the build is working properly. We also tested in our lab using the tools "dishogsync", which is IO stress tool and the tool was provided by Cisco. Issue1: File System going into read-only mode Root cause: The driver tends to not free the memory (FIB) when the management request exits prematurely. The accumulation of such un-freed memory causes the driver to fail to allocate anymore memory (FIB) and hence return 0x70000 value to the upper layer, which puts the file system into read only mode. Fix details: The fix makes sure to free the memory (FIB) even if the request exits prematurely hence ensuring the driver wouldn't run out of memory (FIBs). Issue2: False Raid Alert occurs When the Physical Drives and Logical drives are reported as deleted or added, even though there is no change done on the system Root cause: Driver IOCTLs is signaled with EINTR while waiting on response from the lower layers. Returning "EINTR" will never initiate internal retry. Fix details: The issue was fixed by replacing "EINTR" with "ERESTARTSYS" for mid-layer retries.

It is now not allowed to free up the block-request before cleanup and partial deallocation of the scsi-command. (Which is not so for none bidi commands) The right fix to this problem would be to make bidi command a first citizen by allocating a scsi_sdb pointer at scsi command just like cmd->prot_sdb. The bidi sdb should be allocated/deallocated as part of the get/put_command (Again like the prot_sdb) and the current decoupling of scsi_cmnd and blk-request should be kept. For now make sure scsi_release_buffers() is called before the call to blk_end_request_all() which might cause the suicide of the block requests. At best the leak of bidi buffers, at worse a crash, as there is a race between the existence of the bidi_request and the free of the associated bidi_sdb. The reason this was never hit before is because only OSD has the potential of doing asynchronous bidi commands. (So does bsg but it is never used) And OSD clients just happen to do all their bidi commands synchronously, up until recently.

These errors are caused both by bugs in the Gallium driver and by user-specified index buffers with out of bounds indices. By mmio-tracing the nVidia drivers, I found out how this is done. On DMA_VTX_PROTECTION, The nVidia driver reads the register 0x402000, always getting the value 4, and then writes 4 back to 0x402000. This patch adds that logic by reading 0x402000 and writing the same value back. It's unclear what should happen if the value read is not 4, and the current approach might not be the correct one. To test this, modify mesa/progs/trivial/vbo-drawrange.c, defining ELTOBJ to 1 and replacing indices with huge out of bounds integers. Without this patch, the GPU and/or kernel should lock up. With this patch, it should misrender as expected but not lock up. The errors are still logged since they are useful for development. This has been tested on NV49 and may not work on other cards. To find out how things work on other cards, run the aforementioned test using the blob with mmiotrace and grep for a read of the PGRAPH source register.

The TTM device release will try to evict anything in VRAM to GART memory, but this will fail since sgdma has already been taken down. This causes an infinite loop in kernel mode on module unload. It usually doesn't happen because there aren't any buffer on close. However, if the GPU is locked up, this condition is easily triggered.

This patch doesn't break userspace, it detect "valid" old use of CB_COLOR[0-7]_FRAG & CB_COLOR[0-7]_TILE registers and overwritte the address these registers are pointing to with the one of the last color buffer. This workaround will work for old mesa & xf86-video-ati and any old user which did use similar register programming pattern as those (we expect that there is no others user of those ioctl except possibly a malicious one). This patch add a warning if it detects such usage, warning encourage people to update their mesa & xf86-video-ati. New userspace will submit proper relocation. Fix for xf86-video-ati / mesa (this kernel patch is enough to prevent abuse, fix for userspace are to set proper cs stream and avoid kernel warning) : http://cgit.freedesktop.org/xorg/driver/xf86-video-ati/commit/?id=95d63e408cc88b6934bec84a0b1ef94dfe8bee7b http://cgit.freedesktop.org/mesa/mesa/commit/?id=46dc6fd3ed5ef96cda53641a97bc68c3bc104a9f Abusing this register to perform system ram memory is not easy, here is outline on how it could be achieve. First attacker must have access to the drm device and be able to submit command stream throught cs ioctl. Then attacker must build a proper command stream for r6xx/r7xx hw which will abuse the FRAG or TILE buffer to overwrite the GPU GART which is in VRAM. To achieve so attacker as to setup CB_COLOR[0-7]_FRAG or CB_COLOR[0-7]_TILE to point to the GPU GART, then it has to find a way to write predictable value into those buffer (with little cleverness i believe this can be done but this is an hard task). Once attacker have such program it can overwritte GPU GART to program GPU gart to point anywhere in system memory. It then can reusse same method as he used to reprogram GART to overwritte the system ram through the GART mapping. In the process the attacker has to be carefull to not overwritte any sensitive area of the GART table, like ring or IB gart entry as it will more then likely lead to GPU lockup. Bottom line is that i think it's very hard to use this flaw to get system ram access but in theory one can achieve so. Side note: I am not aware of anyone ever using the GPU as an attack vector, nevertheless we take great care in the opensource driver to try to detect and forbid malicious use of GPU. I don't think the closed source driver are as cautious as we are.

However, we then use the next pointer we stored, which is not guaranteed to be valid. This was apparently the cause of some Nouveau oopses I experienced. This patch rewrites the function so that it keeps the reference to nentry until nentry itself is freed and we already got a reference to nentry->next. v2 updated by me according to Thomas Hellstrom's feedback. v3 proposed by Thomas Hellstrom. Commit comment updated by me. Both updates fixed minor efficiency/style issues only and all three versions should be correct.

The hang is due to a recursive use of the aer_inject lock. The aer_inject() routine grabs the lock while processing the error and then calls pci_read_config_dword to read the masks. The pci_read_config_dword routine is earlier overridden by pci_read_aer, which among other things, grabs the aer_inject lock. Fixed by moving the pci_read_config_dword calls to read the masks to before the lock is taken.

However, the sum of the bare minimum ROM plus all descriptors (from firewire-core, from firewire-net, from userspace) must not exceed 256 quadlets. Otherwise, the bounds of a statically allocated buffer will be overwritten. If the kernel survives that, firewire-core will subsequently be unable to parse the local node's config ROM. (Note, userspace drivers can add descriptors only through device files of local nodes. These are usually only accessible by root, unlike device files of remote nodes which may be accessible to lesser privileged users.) Therefore add a test which takes the actual present and required ROM size into account for all descriptors of kernelspace and userspace drivers.

We need to copy such payloads for each registered userspace client and free the copies according to the lifetime rules of non-FCP client request resources. (This could possibly be optimized by reference counts instead of copies.) The presently only kernelspace driver which listens for FCP requests, firedtv, was not affected because it already copies FCP frames into an own buffer before returning to firewire-core's FCP handler dispatcher.

With luck, this merely prevents video reception. With only a little less luck, the machine crashes. We use the same workaround here as with TSB43AB22/A: Switch off the dual buffer capability flag and use packet-per-buffer IR DMA instead. Another possible workaround would be to limit the coherent DMA mask to 31 bits. In Linux 2.6.33, this change serves effectively only as documentation since dual buffer mode is not used for any controller anymore. But somebody might want to re-enable it in the future to make use of features of dual buffer DMA that are not available in packet-per-buffer mode. In Linux 2.6.32 and older, this update is vital for anyone with this controller, more than 2 GB RAM, a 64 bit kernel, and FireWire video or audio applications.

The above commit changes agp_amd64_init() not to do anything if gart_iommu_aperture is not zero. If GART iommu calls agp_amd64_init(), we need to skip agp_amd64_init() when it's called later via module_init. The problem is that gart_iommu_init() calls agp_amd64_init() with not zero gart_iommu_aperture so agp_amd64_init() is never initialized. When gart_iommu_init() calls agp_amd64_init(), agp should be always initialized.

The LVTMA encoder requires the second digital encoder, all others can use any encoder at all. This fixes the digital encoder selection logic to enable LVDS/DP combos to work okay. V2: fix silly addition of connector dig_block and cleanup the other places in the code that pick the encoder. V3: rename to dig_encoder and clean up further - also fix the picking algorithm. tested on Lenovo W500 + desktop 3650 cards.

This caused a panic in the 1394 async transmit completion tasklet when it dereferenced unitialized list heads: http://bugzilla.kernel.org/show_bug.cgi?id=15077 The fix is to add checks in the tx soft IRQ and in the tasklet to determine which of these two is the last referrer to the transaction object. Then handle the cleanup of the object by the last referrer rather than assuming that the tasklet is always the last one. There is another similar race: Between said tasklet and fwnet_close, i.e. at ifdown. However, that race is much less likely to occur in practice and shall be fixed in a separate update.

Therefore for SPI, TEDG must be equal to REDG, otherwise the last byte received is not sampled in SPI mode 3.

This implements the same D-cache flushing logic for r8a66597-hcd as Catalin's isp1760 (http://patchwork.kernel.org/patch/76391/) change, with the same note applying here as well: When the HDC driver writes the data to the transfer buffers it pollutes the D-cache (unlike DMA drivers where the device writes the data). If the corresponding pages get mapped into user space, there are no additional cache flushing operations performed and this causes random user space faults on architectures with separate I and D caches (Harvard) or those with aliasing D-cache.

It turns out that we really cannot hold 'tty->ctrl_lock' over calling __f_setown, because not only did that cause problems with interrupt disables (which the second commit fixed), it also causes a potential ABBA deadlock due to lock ordering. Thanks to Tetsuo Handa for following up on the issue, and running lockdep to show the problem. It goes roughly like this: - f_getown gets filp->f_owner.lock for reading without interrupts disabled, so an interrupt that happens while that lock is held can cause a lockdep chain from f_owner.lock -> sighand->siglock. - at the same time, the tty->ctrl_lock -> f_owner.lock chain that commit 703625118069 introduced, together with the pre-existing sighand->siglock -> tty->ctrl_lock chain means that we have a lock dependency the other way too. So instead of extending tty->ctrl_lock over the whole __f_setown() call, we now just take a reference to the 'pid' structure while holding the lock, and then release it after having done the __f_setown. That still guarantees that 'struct pid' won't go away from under us, which is all we really ever needed.

In the former case, the ts field of the feed union of struct dmxdev_filter is used, in the latter case the sec field of the same union is used. The ts field is a struct list_head, and is currently initialized in the open() method of the demux device. When for a given demuxer a section filter is set up, the sec field is played with, thus if a PES filter needs to be set up after that the ts field will be corrupted, causing a kernel oops. This fix moves the list head initialization to dvb_dmxdev_pes_filter_set(), so that the ts field is properly initialized every time a PES filter is set up.

This code was written long ago when it was not possible to reshape a degraded array. Now it is so the current level of degraded-ness needs to be taken in to account. Also newly addded devices should only reduce degradedness if they are deemed to be in-sync. In particular, if you convert a RAID5 to a RAID6, and increase the number of devices at the same time, then the 5->6 conversion will make the array degraded so the current code will produce a wrong value for 'degraded' - "-1" to be precise. If the reshape runs to completion end_reshape will calculate a correct new value for 'degraded', but if a device fails during the reshape an incorrect decision might be made based on the incorrect value of "degraded". This patch is suitable for 2.6.32-stable and if they are still open, 2.6.31-stable and 2.6.30-stable as well.

As accessing some md attributes takes the same lock that is held while removing those attributes a deadlock can occur. This patch addresses 3 issues in md that could lead to this deadlock. Two relate to calling flush_scheduled_work while the lock is held. This is probably a bad idea in general and as we use schedule_work to delete various sysfs objects it is particularly bad. In one case flush_scheduled_work is called from md_alloc (called by md_probe) called from do_md_run which holds the lock. This call is only present to ensure that ->gendisk is set. However we can be sure that gendisk is always set (though possibly we couldn't when that code was originally written. This is because do_md_run is called in three different contexts: 1/ from md_ioctl. This requires that md_open has succeeded, and it fails if ->gendisk is not set. 2/ from writing a sysfs attribute. This can only happen if the mddev has been registered in sysfs which happens in md_alloc after ->gendisk has been set. 3/ from autorun_array which is only called by autorun_devices, which checks for ->gendisk to be set before calling autorun_array. So the call to md_probe in do_md_run can be removed, and the check on ->gendisk can also go. In the other case flush_scheduled_work is being called in do_md_stop, purportedly to wait for all md_delayed_delete calls (which delete the component rdevs) to complete. However there really isn't any need to wait for them - they have already been disconnected in all important ways. The third issue is that raid5->stop() removes some attribute names while the lock is held. There is already some infrastructure in place to delay attribute removal until after the lock is released (using schedule_work). So extend that infrastructure to remove the raid5_attrs_group. This does not address all lockdep issues related to the sysfs "s_active" lock. The rest can be address by splitting that lockdep context between symlinks and non-symlinks which hopefully will happen.

(ie they weren't just trying to reserve a port) Currently, if the loopback address is passed to rdma_bind_addr, no device is associated with the rdma_cm_id. Fix this. It turns out that important apps such as Open MPI depend on rdma_bind_addr() NOT associating any RDMA device when binding to a loopback address. Open MPI is being updated to deal with this, but at least until a new Open MPI release is available, maintain the previous behavior: allow rdma_bind_addr() to succeed, but do not bind to a device.

Before changing the status of a buffer with a pending write we will await upon a new flush for that buffer. So we can take advantage of any flushes posted whilst the buffer is active and pending processing by the GPU, by clearing its write_domain and updating its last_rendering_seqno -- thus saving a potential flush in deep queues and improves flushing behaviour upon eviction for both GTT space and fences. In order to reduce the time spent searching the active list for matching write_domains, we move those to a separate list whose elements are the buffers belong to the active/flushing list with pending writes. Orignal patch by Chris Wilson , forward-ported by me. In addition to better performance, this also fixes a real bug. Before this changes, i915_gem_evict_everything didn't work as advertised. When the gpu was actually busy and processing request, the flush and subsequent wait would not move active and dirty buffers to the inactive list, but just to the flushing list. Which triggered the BUG_ON at the end of this function. With the more tight dirty buffer tracking, all currently busy and dirty buffers get moved to the inactive list by one i915_gem_flush operation. I've left the BUG_ON I've used to prove this in there.

At flip finish time, we need to unpin the old fb and decrement the flip pending count on the new buffer. The old code was conflating the two, and led to hangs when new direct rendered apps were started, replacing the existing frame buffer. This patch splits out the buffers and prevents the hangs.

Fix this issue by splitting the i915 suspend into a freeze part a suspend part, where the latter is not executed before creating a hibernation image, and the i915 resume into a "low-level" resume part and a thaw part, where the former is not executed after the image has been created.

This patch corrects a userspace pointer dereference in the VGA arbiter in 2.6.32.1. copy_from_user() is used at line 822 to copy the contents of buf into kbuf, but a call to strncmp() on line 964 uses buf rather than kbuf. This problem led to a GPF in strncmp() when X was started on my x86_32 systems. X triggered the behavior with a write of "target PCI:0000:01:00.0" to /dev/vga_arbiter. The patch has been tested against 2.6.32.1 and observed to correct the GPF observed when starting X or manually writing the string "target PCI:0000:01:00.0" to /dev/vga_arbiter.

When a cycle is lost, the controller will send the packet in the next cycle, instead of terminating the entire DMA program. There are two reasons for this: * This behaviour is compatible with the old IEEE1394 stack. Old applications would not expect the DMA program to stop in this case. * Since the OHCI driver does not report any uncompleted packets, the context would stop silently; clients would not have any chance to detect and handle this error without a watchdog timer. Signed-off-by: Clemens Ladisch Pieter Palmers notes: "The reason I added this retry behavior to the old stack is because some cards now and then fail to send a packet (e.g. the o2micro card in my dell laptop). I couldn't figure out why exactly this happens, my best guess is that the card cannot fetch the payload data on time. This happens much more frequently when sending large packets, which leads me to suspect that there are some contention issues with the DMA that fills the transmit FIFO. In the old stack it was a pretty critical issue as it resulted in a freeze of the userspace application. The omission of a packet doesn't necessarily have to be an issue. E.g. in IEC61883 streams the DBC field can be used to detect discontinuities in the stream. So as long as the other side doesn't bail when no [packet] is present in a cycle, there is not really a problem. I'm not convinced though that retrying is the proper solution, but it is simple and effective for what it had to do. And I think there are no reasons not to do it this way. Userspace can still detect this by checking the cycle the descriptor was sent in."

'overhead_size' is the size of the various header structures used during communication. The first bug is the use of 'sizeof' with the pointer of a structure instead of the structure itself - resulting in the wrong size being computed. This is then used in a check to see if the payload (data_size) would be to large for the preallocated structure. Since the bug produces a smaller value for the overhead, it was possible for the structure to be breached. (Although the current users of the code do not currently send enough data to trigger this bug.) The second bug is that the 'overhead_size' value is used to compute how much of the preallocated space should be cleared before populating it with fresh data. This should have simply been 'sizeof(struct cn_msg)' not overhead_size. The fact that 'overhead_size' was computed incorrectly made this problem "less bad" - leaving only a pointer's worth of space at the end uncleared. Thus, this bug was never producing a bad result, but still needs to be fixed - especially now that the value is computed correctly.

When recovery_complete() is executed between dm_rh_update_states() and dm_writes() in do_mirror(), bios are processed with the region state, DM_RH_NOSYNC. However, the region data is freed without checking its pending count when dm_rh_update_states() is called next time. When bios are finished by mirror_end_io(), __rh_lookup() in dm_rh_dec() returns NULL even though a valid return value are expected. Solution Remove the state change of the recovery failed region from DM_RH_RECOVERING to DM_RH_NOSYNC in dm_rh_recovery_end(). We can remove the state change because: - If the region data has been released by dm_rh_update_states(), a new region data is created with the state of DM_RH_NOSYNC, and bios are processed according to the DM_RH_NOSYNC state. - If the region data has not been released by dm_rh_update_states(), a state of the region is DM_RH_RECOVERING and bios are put in the delayed_bio list. The flag change from DM_RH_RECOVERING to DM_RH_NOSYNC in dm_rh_recovery_end() was added in the following commit: dm raid1: handle resync failures author Jonathan Brassow Thu, 12 Jul 2007 16:29:04 +0000 (17:29 +0100) http://git.kernel.org/linus/f44db678edcc6f4c2779ac43f63f0b9dfa28b724 Signed-off-by: Takahiro Yasui Reviewed-by: Mikulas Patocka Signed-off-by: Alasdair G Kergon --- drivers/md/dm-region-hash.c | 5 ++--- 1 file changed, 2 insertions(+), 3 deletions(-) (limited to 'drivers') diff --git a/drivers/md/dm-region-hash.c b/drivers/md/dm-region-hash.c index 5f19ceb6fe91..168bd38f5006 100644 --- a/drivers/md/dm-region-hash.c +++ b/drivers/md/dm-region-hash.c @@ -660,10 +660,9 @@ void dm_rh_recovery_end(struct dm_region *reg, int success) spin_lock_irq(&rh->region_lock); if (success) list_add(®->list, ®->rh->recovered_regions); - else { - reg->state = DM_RH_NOSYNC; + else list_add(®->list, ®->rh->failed_recovered_regions); - } + spin_unlock_irq(&rh->region_lock); rh->wakeup_workers(rh->context); -- cgit v1.2.1 From 9eef87da2a8ea4920e0d913ff977cac064b68ee0 Mon Sep 17 00:00:00 2001 From: Kiyoshi Ueda Date: Tue, 16 Feb 2010 18:43:01 +0000 Subject: dm mpath: fix stall when requeueing io This patch fixes the problem that system may stall if target's ->map_rq returns DM_MAPIO_REQUEUE in map_request(). E.g. stall happens on 1 CPU box when a dm-mpath device with queue_if_no_path bounces between all-paths-down and paths-up on I/O load. When target's ->map_rq returns DM_MAPIO_REQUEUE, map_request() requeues the request and returns to dm_request_fn(). Then, dm_request_fn() doesn't exit the I/O dispatching loop and continues processing the requeued request again. This map and requeue loop can be done with interrupt disabled, so 1 CPU system can be stalled if this situation happens. For example, commands below can stall my 1 CPU box within 1 minute or so: # dmsetup table mp mp: 0 2097152 multipath 1 queue_if_no_path 0 1 1 service-time 0 1 2 8:144 1 1 # while true; do dd if=/dev/mapper/mp of=/dev/null bs=1M count=100; done & # while true; do \ > dmsetup message mp 0 "fail_path 8:144" \ > dmsetup suspend --noflush mp \ > dmsetup resume mp \ > dmsetup message mp 0 "reinstate_path 8:144" \ > done To fix the problem above, this patch changes dm_request_fn() to exit the I/O dispatching loop once if a request is requeued in map_request().

I think that the calling convention is fundamentally buggered. The caller is the one that did the "reap_as()" to get the as thing, the caller should be the one to free it too. Freeing it in the caller also means that it very clearly always gets freed, and avoids the need for any "free in the error case too".

The transmitter should not be turned off before all characters have been transmitted. serial8250_tx_empty() was reporting that all characters were transmitted before they actually were. === Discovered in parallel with more testing and analysis by Kees Schoenmakers as follows: I ran into an NetMos 9835 serial pci board which behaves a little different than the standard. This type of expansion board is very common. "Standard" 8250 compatible devices clear the 'UART_LST_TEMT" bit together with the "UART_LSR_THRE" bit when writing data to the device. The NetMos device does it slightly different I believe that the TEMT bit is coupled to the shift register. The problem is that after writing data to the device and very quickly after that one does call serial8250_tx_empty, it returns the wrong information. My patch makes the test more robust (and solves the problem) and it does not affect the already correct devices. Alan: We may yet need to quirk this but now we know which chips we have a way to do that should we find this breaks some other 8250 clone with dodgy THRE.
