From 7788cd5557766d49343088b2edc544b186e2fe53 Mon Sep 17 00:00:00 2001 From: Lennert Buytenhek Date: Wed, 23 Dec 2009 16:19:56 +0100 Subject: [PATCH 001/466] [ARM] Orion: fix PCIe inbound window programming when RAM size is not a power of two The PCIe inbound window size is supposed to be a power of two. If the total amount of RAM installed in the system is not a power of two, round it up such that it is.

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 allows to instruct the kernel to do relocations on user-selected addresses, since the relocation bounds checking relies on the request bounds. This can oops the kernel accidentally and is easily exploitable. This patch adds bound checking and alignment checking for ->offset and ->nr_dwords. It also makes some variables unsigned, which should have no effect, but prevents possible bounds checking problems.

The sparc architecture is one of the last 3 arches that need to be converted. This patch applies on top of Linus' current -git tree I've taken my best swing at converting this, but I'm not 100% confident I got it right. My cross-compiler is now out of date (gcc4.2) so I wasn't able to check if it compiled. Any assistance from arch maintainers or testers to get this merged would be great.

When built as modules, the dccp_probe module has a silent dependency on the dccp module. This stems from the fact that the module_init routine of dccp_probe registers a jprobe on the dccp_sendmsg symbol. Since the symbol is only referenced as a text string (the .symbol_name field in the jprobe struct) rather than the address of the symbol itself, depmod never picks this dependency up, and so if you load the dccp_probe module without the dccp module loaded, the register_jprobe call fails with an -EINVAL, and the whole module load fails. The fix is pretty easy, we can just wrap the register_jprobe call in a try_then_request_module call, which forces the dependency to get satisfied prior to the probe registration.

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.

Introduce a zfcp callback for timeouts triggered from FC BSG. With zfcp, the underlying hardware cannot abort CT or ELS requests, so there is nothing to do when the block layer timeout expires. To avoid interference with the block layer timeout, simply indicate that the block layer timer should be reset. The timer running in the hardware for the pending CT or ELS request will return the request when it expires.

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 fixes it in the simplest way possible by cleaning VRAM right before cleaning SGDMA memory.

The bug halt occured because the page that I passed to kfree failed the PageCompound and PageSlab test in the slub implementation of kfree. I tracked the problem down to the following set of events: 1) dccp, unlike all other uses of kmem_cache_create, allocates a string dynamically when registering a slab cache. This allocated string is freed when the cache is destroyed. 2) Normally, (1) is not an issue, but when Slub is in use, it is possible that caches are 'merged'. This process causes multiple caches of simmilar configuration to use the same cache data structure. When this happens, the new name of the cache is effectively dropped. 3) (2) results in kmem_cache_name returning an ambigous value (i.e. ccid_kmem_cache_destroy, which uses this fuction to retrieve the name pointer for freeing), is no longer guaranteed that the string it assigned is what is returned. 4) If such merge event occurs, ccid_kmem_cache_destroy frees the wrong pointer, which trips over the BUG in the slub implementation of kfree (since its likely not a slab allocation, but rather a pointer into the static string table section. So, what to do about this. At first blush this is pretty clearly a leak in the information that slub owns, and as such a slub bug. Unfortunately, theres no really good way to fix it, without exposing slub specific implementation details to the generic slab interface. Also, even if we could fix this in slub cleanly, I think the RCU free option would force us to do lots of string duplication, not only in slub, but in every slab allocator. As such, I'd like to propose this solution. Basically, I just move the storage for the kmem cache name to the ccid_operations structure. In so doing, we don't have to do the kstrdup or kfree when we allocate/free the various caches for dccp, and so we avoid the problem, by storing names with static memory, rather than heap, the way all other calls to kmem_cache_create do. I've tested this out myself here, and it solves the problem quite well. Signed-off-by: Neil Horman Acked-by: Arnaldo Carvalho de Melo Signed-off-by: David S.

Unable to handle kernel NULL pointer dereference at virtual address 00000000 [...] Backtrace: [] (__bug+0x0/0x2c) from [] (queue_delayed_work_on+0x74/0xf8) [] (queue_delayed_work_on+0x0/0xf8) from [] (queue_delayed_work+0x2c/0x30) The oops pops up because TI DaVinci EMAC driver detaches PHY on suspend and attaches it back on resume. Attaching makes phylib call phy_start_machine() that initializes a workqueue. On the other hand, PHY's resume routine will call phy_start_machine() again, and that will cause the oops since we just destroyed the already scheduled workqueue. This patch fixes the issue by moving workqueue initialization to phy_device_create(). p.s. We don't see this oops with ucc_geth and gianfar drivers because they perform a fine-grained suspend, i.e. they just stop the PHYs without detaching.

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.

Apparently some of their testing revealed that they were able to force a buffer fragment in e1000 in which the trailing fragment was greater than 4 bytes. As a result the fragment check I introduced failed to detect the fragement and a partial invalid frame was passed up into the network stack. I've written this patch to correct it. I'm in the process of testing it now, but it makes good logical sense to me. Effectively it maintains a per-adapter state variable which detects a non-EOP frame, and discards it and subsequent non-EOP frames leading up to _and_ _including_ the next positive-EOP frame (as it is by definition the last fragment). This should prevent any and all partial frames from entering the network stack from e1000. Signed-off-by: Jesse Brandeburg Acked-by: Neil Horman Signed-off-by: Jeff Kirsher Signed-off-by: David S.

Unequivocally setting the bit in nodes_parsed is insufficient since existing code, such as acpi_get_nodes(), assumes all nodes in the map have online address ranges. In fact, all code using nodes_parsed assumes such nodes represent an address range of online memory. nodes_possible_map is created by unioning nodes_parsed and cpu_nodes_parsed; the former represents nodes with online memory and the latter represents memoryless nodes. We now set the bit for hotpluggable nodes in cpu_nodes_parsed so that it also gets set in nodes_possible_map.

Commit d1c84f79a6ba992dc01e312c44a21496303874d6 leads to a regression when microcode_amd.c is compiled into the kernel. It causes a big boot delay because the firmware is not available. See http://marc.info/?l=linux-kernel&m=126267290920060 It also renders the reload sysfs attribute useless. Fixing this is too intrusive for an -rc5 kernel.

The 1024 byte descriptor used with the 1000 mtu test also (re) introduced the (originally) reported bug, and causes us to need the e1000_clean_tx_irq "enhance frame fragment detection" fix. So what has occured here is that 2.6.32 is only vulnerable for mtu < 1500 due to the jumbo specific routines in both e1000 and e1000e. So, 2.6.32 needs the 2kB buffer len fix for those smaller MTUs, but is not vulnerable to the original issue reported. It has been pointed out that this vulnerability needs to be patched in older kernels that don't have the e1000 jumbo routine. Without the jumbo routines, we need the "enhance frame fragment detection" fix the e1000, old e1000e is only vulnerable for < 1500 mtu, and needs a similar fix. We split the patches up to provide easy backport paths. There is only a slight bit of extra code when this fix and the original "enhance frame fragment detection" fixes are applied, so please apply both, even though it is a bit of overkill.

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.

B1 power-off This patch fixes power LED blinking and power-off on DNS-323 rev. B1. GPIO pin 3 has to be set to 1 to stop power LED blinking and to allow the LED to be controlled via leds-gpio. This pin has to be also set to 1 for power-off to work. To power-off the rev. B1 machine, pin 8 has to be set to 1 and then set to 0 to do actual power-off. Tested on my DNS-323 rev.

The vcpu can pick up the IRR and inject the interrupt before setting the TMR, and perhaps even EOI it, causing incorrect behaviour. The race is really insignificant since it can only occur on the first interrupt (usually following interrupts will not change TMR), but it's better closed than open.

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.

After the stall, the RX buffer is empty on the guest side and there are exactly 16 entries available on the host side. As the number of entries is less than that required by a maximal skb, the host cannot proceed. The guest did not have a refill job scheduled. My diagnosis is that an OOM had occured, with the delayed refill job scheduled. The job was able to allocate at least one skb, but not enough to overcome the minimum required by the host to proceed. As the refill job would only reschedule itself if it failed completely to allocate any skbs, this would lead to an RX stall. The following patch removes this stall possibility by always rescheduling the refill job until the ring is totally refilled. Testing has shown that the RX stall no longer occurs whereas previously it would occur within a day. Signed-off-by: Herbert Xu Acked-by: Rusty Russell Signed-off-by: David S.

When the kernel is stopped by kgdb inside code which holds watchdog_lock then kgdb dead locks in clocksource_resume_watchdog(). clocksource_resume_watchdog() is called from kbdg via clocksource_touch_watchdog() to avoid that the clock source watchdog marks TSC unstable after the kernel has been stopped. Solve this by replacing spin_lock with a spin_trylock and just return in case the lock is held. Not resetting the watchdog might result in TSC becoming marked unstable, but that's an acceptable penalty for using kgdb. The timekeeping is anyway easily screwed up by kgdb when the system uses either jiffies or a clock source which wraps in short intervals (e.g. pm_timer wraps about every 4.6s), so we really do not have to worry about that occasional TSC marked unstable side effect. The second caller of clocksource_resume_watchdog() is clocksource_resume(). The trylock is safe here as well because the system is UP at this point, interrupts are disabled and nothing else can hold watchdog_lock().

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.

There are two types of reads from the ring buffer. One is a consuming read which will consume the entry that was read and the next read will be the entry that follows. The other is an iterator that will let the user read the contents of the ring buffer without modifying it. When an iterator is allocated, writes to the ring buffer are disabled to protect the iterator. The problem exists when consuming reads happen while an iterator is allocated. Specifically, the kind of read that swaps out an entire page (used by splice) and replaces it with a new read. If the iterator is on the page that is swapped out, then the next read may read from this swapped out page and return garbage. This patch adds a check when reading the iterator to make sure that the iterator contents are still valid. If a consuming read has taken place, the iterator is reset.

In particular, the intel GPU object mapping code wants to be able to do a certain amount of own internal memory management by automatically shrinking the address space when memory starts getting tight. This allows it to dynamically use different memory allocation policies on a per-allocation basis, rather than depend on the (static) address space gfp policy. The actual new function is a one-liner, but re-organizing the helper functions to the point where you can do this with a single line of code is what most of the patch is all about.

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.

Patch Changelog: Version 2 - simplified method by using 'expr' for 'substr' and making it work with dash once again Version 1 - Revert the removals of '-n "$(VMLINUX_SIZE)"' to avoid the error of "make clean" - Consider more cases of the VMLINUX_LOAD_ADDRESS Version 0 - initial release Signed-off-by: Alexander Clouter Acked-by: Wu Zhangjin Patchwork: http://patchwork.linux-mips.org/patch/861/ Signed-off-by: Ralf Baechle --- arch/mips/boot/compressed/Makefile | 7 +++++-- 1 file changed, 5 insertions(+), 2 deletions(-) diff --git a/arch/mips/boot/compressed/Makefile b/arch/mips/boot/compressed/Makefile index bdcfd49f022d..9df903d714d7 100644 --- a/arch/mips/boot/compressed/Makefile +++ b/arch/mips/boot/compressed/Makefile @@ -14,8 +14,11 @@ # compressed kernel load addr: VMLINUZ_LOAD_ADDRESS > VMLINUX_LOAD_ADDRESS + VMLINUX_SIZE VMLINUX_SIZE := $(shell wc -c $(objtree)/$(KBUILD_IMAGE) 2>/dev/null | cut -d' ' -f1) -VMLINUX_SIZE := $(shell [ -n "$(VMLINUX_SIZE)" ] && echo $$(($(VMLINUX_SIZE) + (65536 - $(VMLINUX_SIZE) % 65536)))) -VMLINUZ_LOAD_ADDRESS := 0x$(shell [ -n "$(VMLINUX_SIZE)" ] && printf %x $$(($(VMLINUX_LOAD_ADDRESS) + $(VMLINUX_SIZE)))) +VMLINUX_SIZE := $(shell [ -n "$(VMLINUX_SIZE)" ] && echo -n $$(($(VMLINUX_SIZE) + (65536 - $(VMLINUX_SIZE) % 65536)))) +# VMLINUZ_LOAD_ADDRESS = concat "high32 of VMLINUX_LOAD_ADDRESS" and "(low32 of VMLINUX_LOAD_ADDRESS) + VMLINUX_SIZE" +HIGH32 := $(shell A=$(VMLINUX_LOAD_ADDRESS); [ $${\#A} -gt 10 ] && expr substr "$(VMLINUX_LOAD_ADDRESS)" 3 $$(($${\#A} - 10))) +LOW32 := $(shell [ -n "$(HIGH32)" ] && A=11 || A=3; expr substr "$(VMLINUX_LOAD_ADDRESS)" $${A} 8) +VMLINUZ_LOAD_ADDRESS := 0x$(shell [ -n "$(VMLINUX_SIZE)" -a -n "$(LOW32)" ] && printf "$(HIGH32)%08x" $$(($(VMLINUX_SIZE) + 0x$(LOW32)))) # set the default size of the mallocing area for decompressing BOOT_HEAP_SIZE := 0x400000 From 59dfa2fcaecc39fb88bfa196cb15adca7146867a Mon Sep 17 00:00:00 2001 From: David VomLehn Date: Wed, 23 Dec 2009 17:34:46 -0800 Subject: [PATCH 289/466] MIPS: PowerTV: Streamline access to platform device registers Pre-compute addresses for the basic ASIC registers. This speeds up access and allows memory for unused configurations to be freed. In addition, uninitialized register addresses will be returned as NULL to catch bad usage quickly.

Using a greater number without IRQ sharing requires reading platform-specific registers. On such platforms, reading the IntCtl register to determine which interrupt corresponds to a timer interrupt will not work. On MIPSR2 systems there is a solution - the TI bit in the Cause register, specifically indicates that a timer interrupt has occured. This patch uses that bit to detect interrupts for MIPSR2 processors, which may be expected to work regardless of how the timer interrupt may be routed in the hardware.

On a given architecture, when hardware breakpoint registration fails due to un-supported access type (read/write/execute), we lose the bp slot since register_perf_hw_breakpoint() does not release the bp slot on failure.

This can save considerable CPU because all future writes to the file go through uncompressed. But some files are both very large and have mixed data stored in them. In that case, we want to add the ability to always try compressing data before writing it. This commit adds mount -o compress-force. A later commit will add a new inode flag that does the same thing.

The reason is the sanity check only looks at the total number of rw devices, which is just 2 because we have 2 good disks and 1 bad one. Instead check the total number of devices in the array to make sure we can actually remove the device. Tested this with a failed disk setup and with this test we can now run btrfs-vol -r missing /mount/point and it works fine.

It doesn't just flush the old executable environment, it also starts up the new one. Which is very inconvenient for things like setting up the new personality, because we want the new personality to affect the starting of the new environment, but at the same time we do _not_ want the new personality to take effect if flushing the old one fails. As a result, the x86-64 '32-bit' personality is actually done using this insane "I'm going to change the ABI, but I haven't done it yet" bit (TIF_ABI_PENDING), with SET_PERSONALITY() not actually setting the personality, but just the "pending" bit, so that "flush_thread()" can do the actual personality magic. This patch in no way changes any of that insanity, but it does split the 'flush_old_exec()' function up into a preparatory part that can fail (still called flush_old_exec()), and a new part that will actually set up the new exec environment (setup_new_exec()). All callers are changed to trivially comply with the new world order. Signed-off-by: H.

Fix that in the most straightforward way (which, considering the overheads of alternative approaches, is Mel's preference): the right migratetype is already in page_private(page), but free_pcppages_bulk() wasn't using it. How did this bug show up? As a 20% slowdown in my tmpfs loop kbuild swapping tests, on PowerMac G5 with SLUB allocator. Bisecting to that commit was easy, but explaining the magnitude of the slowdown not easy. The same effect appears, but much less markedly, with SLAB, and even less markedly on other machines (the PowerMac divides into fewer zones than x86, I think that may be a factor). We guess that lumpy reclaim of short-lived high-order pages is implicated in some way, and probably this bug has been tickling a poor decision somewhere in page reclaim. But instrumentation hasn't told me much, I've run out of time and imagination to determine exactly what's going on, and shouldn't hold up the fix any longer: it's valid, and might even fix other misbehaviours.

The hw_breakpoint_handler() now consumes the hw breakpoints that were previously set by kgdb arch specific code. In order for kgdb to work in conjunction with this core API change, kgdb must use some of the low level functions of the hw_breakpoint API to install, uninstall, and deal with hw breakpoint reservations. The kgdb core required a change to call kgdb_disable_hw_debug anytime a slave cpu enters kgdb_wait() in order to keep all the hw breakpoints in sync as well as to prevent hitting a hw breakpoint while kgdb is active. During the architecture specific initialization of kgdb, it will pre-allocate 4 disabled (struct perf event **) structures. Kgdb will use these to manage the capabilities for the 4 hw breakpoint registers, per cpu. Right now the hw_breakpoint API does not have a way to ask how many breakpoints are available, on each CPU so it is possible that the install of a breakpoint might fail when kgdb restores the system to the run state. The intent of this patch is to first get the basic functionality of hw breakpoints working and leave it to the person debugging the kernel to understand what hw breakpoints are in use and what restrictions have been imposed as a result. Breakpoint constraints will be dealt with in a future patch. While atomic, the x86 specific kgdb code will call arch_uninstall_hw_breakpoint() and arch_install_hw_breakpoint() to manage the cpu specific hw breakpoints. The net result of these changes allow kgdb to use the same pool of hw_breakpoints that are used by the perf event API, but neither knows about future reservations for the available hw breakpoint slots.

The kernel debugger cannot use any mutex_lock() calls because it can start the kernel running from an invalid context. A mutex free version of the reservation API needed to get created for the kernel debugger to safely update hw breakpoint reservations. The possibility for a breakpoint reservation to be concurrently processed at the time that kgdb interrupts the system is improbable. Should this corner case occur the end user is warned, and the kernel debugger will prohibit updating the hardware breakpoint reservations. Any time the kernel debugger reserves a hardware breakpoint it will be a system wide reservation.

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.

In this configuration kgdb will report a softlock warning message on resuming or detaching from a debug session. Sequence of events in the problem case: 1) "cpu sched clock" and "hardware time" are at 100 sec prior to a call to kgdb_handle_exception() 2) Debugger waits in kgdb_handle_exception() for 80 sec and on exit the following is called ... touch_softlockup_watchdog() --> __raw_get_cpu_var(touch_timestamp) = 0; 3) "cpu sched clock" = 100s (it was not updated, because the interrupt was disabled in kgdb) but the "hardware time" = 180 sec 4) The first timer interrupt after resuming from kgdb_handle_exception updates the watchdog from the "cpu sched clock" update_process_times() { ... run_local_timers() --> softlockup_tick() --> check (touch_timestamp == 0) (it is "YES" here, we have set "touch_timestamp = 0" at kgdb) --> __touch_softlockup_watchdog() ***(A)--> reset "touch_timestamp" to "get_timestamp()" (Here, the "touch_timestamp" will still be set to 100s.) ... scheduler_tick() ***(B)--> sched_clock_tick() (update "cpu sched clock" to "hardware time" = 180s) ... } 5) The Second timer interrupt handler appears to have a large jump and trips the softlockup warning. update_process_times() { ... run_local_timers() --> softlockup_tick() --> "cpu sched clock" - "touch_timestamp" = 180s-100s > 60s --> printk "soft lockup error messages" ... } note: ***(A) reset "touch_timestamp" to "get_timestamp(this_cpu)" Why is "touch_timestamp" 100 sec, instead of 180 sec? When CONFIG_HAVE_UNSTABLE_SCHED_CLOCK is set, the call trace of get_timestamp() is: get_timestamp(this_cpu) -->cpu_clock(this_cpu) -->sched_clock_cpu(this_cpu) -->__update_sched_clock(sched_clock_data, now) The __update_sched_clock() function uses the GTOD tick value to create a window to normalize the "now" values. So if "now" value is too big for sched_clock_data, it will be ignored. The fix is to invoke sched_clock_tick() to update "cpu sched clock" in order to recover from this state. This is done by introducing the function touch_softlockup_watchdog_sync(). This allows kgdb to request that the sched clock is updated when the watchdog thread runs the first time after a resume from kgdb.

DBDMA descriptors need to be located at 32-byte aligned addresses; however kmalloc in conjunction with the SLAB allocator and CONFIG_DEBUG_SLUB enabled doesn't deliver any. The dbdma code works around that by allocating a larger area and realigning the start address within it.

I am reposting it with more test results. This patch does two things. - Do not idle on async queues. - It also changes the write queue depth CFQ drives (cfq_may_dispatch()). Currently, we seem to driving queue depth of 1 always for WRITES. This is true even if there is only one write queue in the system and all the logic of infinite queue depth in case of single busy queue as well as slowly increasing queue depth based on last delayed sync request does not seem to be kicking in at all. This patch will allow deeper WRITE queue depths (subjected to the other WRITE queue depth contstraints like cfq_quantum and last delayed sync request). Shaohua Li had reported getting more out of his SSD. For me, I have got one Lun exported from an HP EVA and when pure buffered writes are on, I can get more out of the system. Following are test results of pure buffered writes (with end_fsync=1) with vanilla and patched kernel. These results are average of 3 sets of run with increasing number of threads.

With some random and sequential reads going on in the system on one SATA disk I did not see any significant increase in max clat. So it looks like other WRITE queue depth control logic is doing its job. Here are the results.

That made sense from a technical standpoint, but when we then also combined it with the actual personality setting going in between flush_old_exec() and setup_new_exec(), it needs to be a bit more careful. In particular, we need to make sure that we really flush the old personality bits in the 'flush' stage, rather than later in the 'setup' stage, since otherwise we might be flushing the _new_ personality state that we're just setting up. So this moves the flags and personality flushing (and 'flush_thread()', which is the arch-specific function that generally resets lazy FP state etc) of the old process into flush_old_exec(), so that it doesn't affect any state that execve() is setting up for the new process environment.

While we are there, remove a couple of unused fields from an earlier iteration. These APIs aren't actually used anywhere, because of problems with the XFS conversion. Christoph has now verified that the problems are solved with these patches. Also it is an exported interface, so I think it will be good to be merged now (and Christoph wants to get the XFS changes into their local tree).

We previously don't free up per-CPU maps until all its addresses have been used and freed. So fragmented blocks could fill up vmalloc space even if they actually had no active vmap regions within them. Add some logic to allow all CPUs to have these blocks purged in the case of failure to allocate a new vm area, and also put some logic to trim such blocks of a current CPU if we hit them in the allocation path (so as to avoid a large build up of them). Christoph reported some vmap allocation failures when using the per CPU vmap APIs in XFS, which cannot be reproduced after this patch and the previous bug fix.

Getting it is not used, let's drop support for notifications about (un)registered events from connector. Another option was to check credentials on receiving, but we can always restore it without bugs if needed, but genetlink has a wider code base and none complained, that userspace can not get notification when some other clients were (un)registered.

With IDR_BITS of 6, it grows to three layers when id 4096 is first allocated. When that happens, idr wraps incorrectly and searches the idr array ignoring the high bits. The following test code from Eric demonstrates the bug nicely. #include #include #include static DEFINE_IDR(test_idr); int init_module(void) { int ret, forty95, forty96; void *addr; /* add 2 entries both with 4095 as the start address */ again1: if (!idr_pre_get(&test_idr, GFP_KERNEL)) return -ENOMEM; ret = idr_get_new_above(&test_idr, (void *)4095, 4095, &forty95); if (ret) { if (ret == -EAGAIN) goto again1; return ret; } if (forty95 != 4095) printk(KERN_ERR "hmmm, forty95=%d\n", forty95); again2: if (!idr_pre_get(&test_idr, GFP_KERNEL)) return -ENOMEM; ret = idr_get_new_above(&test_idr, (void *)4096, 4095, &forty96); if (ret) { if (ret == -EAGAIN) goto again2; return ret; } if (forty96 != 4096) printk(KERN_ERR "hmmm, forty96=%d\n", forty96); /* try to find the 2 entries, noticing that 4096 broke */ addr = idr_find(&test_idr, forty95); if ((int)addr != forty95) printk(KERN_ERR "hmmm, after find forty95=%d addr=%d\n", forty95, (int)addr); addr = idr_find(&test_idr, forty96); if ((int)addr != forty96) printk(KERN_ERR "hmmm, after find forty96=%d addr=%d\n", forty96, (int)addr); /* really weird, the entry which should be at 4096 is actually at 0!! */ addr = idr_find(&test_idr, 0); if ((int)addr) printk(KERN_ERR "found an entry at id=0 for addr=%d\n", (int)addr); idr_remove(&test_idr, forty95); idr_remove(&test_idr, forty96); return 0; } void cleanup_module(void) { } MODULE_AUTHOR("Eric Paris "); MODULE_DESCRIPTION("Simple idr test"); MODULE_LICENSE("GPL"); This happens because when sub_alloc() back tracks it doesn't always do it step-by-step while the over-the-limit detection assumes step-by-step backtracking. The logic in sub_alloc() looks like the following. restart: clear pa[top level + 1] for end cond detection l = top level while (true) { search for empty slot at this level if (not found) { push id to the next possible value l++ A: if (pa[l] is clear) failed, return asking caller to grow the tree if (going up 1 level gives more slots to search) continue the while loop above with the incremented l else C: goto restart } adjust id accordingly to the found slot if (l == 0) return found id; create lower level if not there yet record pa[l] and l-- } Test A is the fail exit condition but this assumes that failure is propagated upwared one level at a time but the B optimization path breaks the assumption and restarts the whole thing with a start value which is above the possible limit with the current layers. sub_alloc() assumes the start id value is inside the limit when called and test A is the only exit condition check, so it ends up searching for empty slot while ignoring high set bit. So, for 4095->4096 test, level0 search fails but pa[1] contains a valid pointer. However, going up 1 level wouldn't give any more empty slot so it takes C and when the whole thing restarts nobody notices the high bit set beyond the top level. This patch fixes the bug by changing the fail exit condition check to full id limit check.

So the right steps should be: flush_dcache_page(page); kmap_atomic(page); write to page; kunmap_atomic(page); flush_dcache_page(page); More precisely, we might create two new APIs flush_dcache_user_page and flush_dcache_kern_page to replace the two flush_dcache_page accordingly. Here is a snippet tested on omap2430 with VIPT cache, and I think it is not ARM-specific: int val = 0x11111111; fd = open("abc", O_RDWR); addr = mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_SHARED, fd, 0); *(addr+0) = 0x44444444; tmp = *(addr+0); *(addr+1) = 0x77777777; write(fd, &val, sizeof(int)); close(fd); The results are not always 0x11111111 0x77777777 at the beginning as expected.

If the futex is created in a temporary file in an ext3 file system, this bug causes the file's inode to become an "undead" orphan, which causes an oops from a BUG_ON() in ext3_put_super() when the file system is unmounted. glibc's test suite is known to trigger this, see . The bug is a regression from 2.6.28-git3, namely Peter Zijlstra's 38d47c1b7075bd7ec3881141bb3629da58f88dab "[PATCH] futex: rely on get_user_pages() for shared futexes". That commit made get_futex_key() also increment the reference count of the futex key, and updated its callers to decrement the key's reference count before returning. Unfortunately the normal exit path in futex_lock_pi() wasn't corrected: the reference count is incremented by get_futex_key() and queue_lock(), but the normal exit path only decrements once, via unqueue_me_pi(). The fix is to put_futex_key() after unqueue_me_pi(), since 2.6.31 this is easily done by 'goto out_put_key' rather than 'goto out'.

When a malicious or just sloppy programmed user space application sets the futex value to 0 e.g. by calling pthread_mutex_init(), then the futex can be acquired again. A new waiter manages to enqueue itself on the pi_state w/o damage, but on unlock the kernel dereferences pi_state->owner and oopses. Prevent this by checking pi_state->owner in the unlock path. If pi_state->owner is not current we know that user space manipulated the futex value. Ignore the mess and return -EINVAL. This catches the above case and also the case where a task hijacks the futex by setting the tid value and then tries to unlock it.

The following is steps to reproduce it. # mkfs.btrfs /dev/sda2 # mount /dev/sda2 /mnt # mkfs.btrfs /dev/sda1 /dev/sda2 (the program says that /dev/sda2 was mounted, and then exits. ) # umount /mnt # mount /dev/sda1 /mnt At the third step, mkfs.btrfs exited in the way of make filesystem. So the initialization of the filesystem didn't finish. So the filesystem was bad, and it caused BUG_ON() when mounting it. But BUG_ON() should be called by the wrong code, not user's operation, so I think it is a bug of btrfs. This patch fixes it.

Some declare the whole range of I/O ports (8 ports), some declare only the useful ports (2 ports at offset 5) and some declare fancy ranges, for example 4 ports at offset 4. To properly handle all cases, request all ports individually for probing. After we have determined that we really have a W83781D or W83782D chip, the useful port range will be requested again, as a single block. I did not see a board which needs this yet, but I know of one for lm78 driver and I'd like to keep the logic of these two drivers in sync.

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.
