433e2f3 Will Deacon 04 July 2012, 17:17:16 UTC ARM: 7443/1: Revert "new way of handling ERESTART_RESTARTBLOCK" This reverts commit 6b5c8045ecc7e726cdaa2a9d9c8e5008050e1252. Conflicts: arch/arm/kernel/ptrace.c The new syscall restarting code can lead to problems if we take an interrupt in userspace just before restarting the svc instruction. If a signal is delivered when returning from the interrupt, the TIF_SYSCALL_RESTARTSYS will remain set and cause any syscalls executed from the signal handler to be treated as a restart of the previously interrupted system call. This includes the final sigreturn call, meaning that we may fail to exit from the signal context. Furthermore, if a system call made from the signal handler requires a restart via the restart_block, it is possible to clear the thread flag and fail to restart the originally interrupted system call. The right solution to this problem is to perform the restarting in the kernel, avoiding the possibility of handling a further signal before the restart is complete. Since we're almost at -rc6, let's revert the new method for now and aim for in-kernel restarting at a later date.

dab058f Linus Torvalds 03 July 2012, 22:51:22 UTC floppy: cancel any pending fd_timeouts before adding a new one In commit 070ad7e793dc ("floppy: convert to delayed work and single-thread wq") the 'fd_timeout' timer was converted to a delayed work. However, the "del_timer(&fd_timeout)" was lost in the process, and any previous pending timeouts would stay active when we then re-queued the timeout. This resulted in the floppy probe sequence having a (stale) 20s timeout rather than the intended 3s timeout, and thus made booting with the floppy driver (but no actual floppy controller) take much longer than it should. Of course, there's little reason for most people to compile the floppy driver into the kernel at all, which is why most people never noticed. Canceling the delayed work where we used to do the del_timer() fixes the issue, and makes the floppy probing use the proper new timeout instead. The three second timeout is still very wasteful, but better than the 20s one.

0d200ae Joe Thornber 03 July 2012, 11:55:31 UTC dm thin: commit metadata before creating metadata snapshot Userland sometimes sees a corrupt metadata block if metadata is changing rapidly when a metadata snapshot is reserved for userland, To make the problem go away, commit before we take the metadata snapshot (which is a sensible thing to do anyway). The checksums mean userland spots this corruption immediately so there's no risk of acting on incorrect data. No corruption exists from the kernel's point of view, and thin_check passes after pool shutdown. I believe this is to do with shared blocks at the first level of the {device, mapping} btree. Prior to the metadata-snap support no sharing at this level was possible, so this patch is only required after commit cc8394d86f045b86ff303d3c9e4ce47d97148951 ("dm thin: provide userspace access to pool metadata").

9f846a1 Daniel Vetter 01 July 2012, 15:09:42 UTC drm/i915: kick any firmware framebuffers before claiming the gtt Especially vesafb likes to map everything as uc- (yikes), and if that mapping hangs around still while we try to map the gtt as wc the kernel will downgrade our request to uc-, resulting in abyssal performance. Unfortunately we can't do this as early as readon does (i.e. as the first thing we do when initializing the hw) because our fb/mmio space region moves around on a per-gen basis. So I've had to move it below the gtt initialization, but that seems to work, too. The important thing is that we do this before we set up the gtt wc mapping. Now an altogether different question is why people compile their kernels with vesafb enabled, but I guess making things just work isn't bad per se ... v2: - s/radeondrmfb/inteldrmfb/ - fix up error handling v3: Kill #ifdef X86, this is Intel after all. Noticed by Ben Widawsky. v4: Jani Nikula complained about the pointless bool primary initialization. v5: Don't oops if we can't allocate, noticed by Chris Wilson. v6: Resolve conflicts with agp rework and fixup whitespace. This is commit e188719a2891f01b3100d in drm-next. Backport to 3.5 -fixes queue requested by Dave Airlie - due to grub using vesa on fedora their initrd seems to load vesafb before loading the real kms driver.

Meanwhile the recent changes for allowing more modes in the GFT/CVT ranges give actually more modes, and some modes may be over the native size. Thus such a mode would be picked up as the preferred mode although it's no native resolution. For avoiding such a problem, this patch limits the addition of inferred modes by checking not to be greater than other modes. Also, it checks the duplicated mode entry at the same time.

b357f04 NeilBrown 03 July 2012, 07:45:31 UTC md: fix up plugging (again). The value returned by "mddev_check_plug" is only valid until the next 'schedule' as that will unplug things. This could happen at any call to mempool_alloc. So just calling mddev_check_plug at the start doesn't really make sense. So call it just before, or just after, queuing things for the thread. As the action that happens at unplug is to wake the thread, this makes lots of sense. If we cannot add a plug (which requires a small GFP_ATOMIC alloc) we wake thread immediately. RAID5 is a bit different. Requests are queued for the thread and the thread is woken by release_stripe. So we don't need to wake the thread on failure. However the thread doesn't perform certain actions when there is any active plug, so it is important to install a plug before waking the thread. So for RAID5 we install the plug *before* queuing the request and waking the thread. Without this patch it is possible for raid1 or raid10 to queue a request without then waking the thread, resulting in the array locking up. Also change raid10 to only flush_pending_write when there are not active plugs, just like raid1. This patch is suitable for 3.0 or later. I plan to submit it to -stable, but I'll like to let it spend a few weeks in mainline first to be sure it is completely safe. Signed-off-by: NeilBrown <neilb@suse.de> 03 July 2012, 07:45:31 UTC

If a stripe has both the bits set, such stripe will be in delayed list and preread count not 0, which will make such stripe never leave delayed list.

I'm not sure why we are still open coding this but iterating above nr_cpu_ids is definitely a bug. This patch iterates through all possible cpus, in case we issue a system reset and CPUs in an offline state call in. Perhaps the old code was trying to handle CPUs that were in the partition but were never started (eg kexec into a kernel with an nr_cpus= boot option).

However, static mappings always were allowed to use separate 1MB section entries. This means in practice that a static mapping may create half populated PMDs via create_mapping(). Since commit 0536bdf33f (ARM: move iotable mappings within the vmalloc region) those static mappings are located in the vmalloc area. We must ensure no such half populated PMDs are accessible once vmalloc() or ioremap() start looking at the vmalloc area for nearby free virtual address ranges, or various things leading to a kernel crash will happen.

2e1706f Bruce Allan 30 June 2012, 20:02:42 UTC e1000e: remove use of IP payload checksum Currently only used when packet split mode is enabled with jumbo frames, IP payload checksum (for fragmented UDP packets) is mutually exclusive with receive hashing offload since the hardware uses the same space in the receive descriptor for the hardware-provided packet checksum and the RSS hash, respectively. Users currently must disable jumbos when receive hashing offload is enabled, or vice versa, because of this incompatibility. Since testing has shown that IP payload checksum does not provide any real benefit, just remove it so that there is no longer a choice between jumbos or receive hashing offload but not both as done in other Intel GbE drivers (e.g. e1000, igb). Also, add a missing check for IP checksum error reported by the hardware; let the stack verify the checksum when this happens.

4244854 Neil Horman 30 June 2012, 03:04:26 UTC sctp: be more restrictive in transport selection on bundled sacks It was noticed recently that when we send data on a transport, its possible that we might bundle a sack that arrived on a different transport. While this isn't a major problem, it does go against the SHOULD requirement in section 6.4 of RFC 2960: An endpoint SHOULD transmit reply chunks (e.g., SACK, HEARTBEAT ACK, etc.) to the same destination transport address from which it received the DATA or control chunk to which it is replying. This rule should also be followed if the endpoint is bundling DATA chunks together with the reply chunk. This patch seeks to correct that. It restricts the bundling of sack operations to only those transports which have moved the ctsn of the association forward since the last sack. By doing this we guarantee that we only bundle outbound saks on a transport that has received a chunk since the last sack. This brings us into stricter compliance with the RFC. Vlad had initially suggested that we strictly allow only sack bundling on the transport that last moved the ctsn forward. While this makes sense, I was concerned that doing so prevented us from bundling in the case where we had received chunks that moved the ctsn on multiple transports. In those cases, the RFC allows us to select any of the transports having received chunks to bundle the sack on. so I've modified the approach to allow for that, by adding a state variable to each transport that tracks weather it has moved the ctsn since the last sack. This I think keeps our behavior (and performance), close enough to our current profile that I think we can do this without a sysctl knob to enable/disable it.

Put together the two 'cont.len && cont.owner == current' if statements into a single one, and check if we need to call cont_add(). This also removes the unneeded double cont_flush() calls.

084681d Kay Sievers 28 June 2012, 07:38:53 UTC printk: flush continuation lines immediately to console Continuation lines are buffered internally, intended to merge the chunked printk()s into a single record, and to isolate potentially racy continuation users from usual terminated line users. This though, has the effect that partial lines are not printed to the console in the moment they are emitted. In case the kernel crashes in the meantime, the potentially interesting printed information would never reach the consoles. Here we share the continuation buffer with the console copy logic, and partial lines are always immediately flushed to the available consoles. They are still buffered internally to improve the readability and integrity of the messages and minimize the amount of needed record headers to store.

c21b328 Alex Deucher 28 June 2012, 21:53:07 UTC drm/radeon: fix VM page table setup on SI Cayman and trinity allow for variable sized VM page tables, but SI requires that all page tables be the same size. The current code assumes variablely sized VM page tables so SI may end up with part of each page table overlapping with other memory which could end up being interpreted by the VM hw as garbage. Change the code to better accomodate SI. Allocate enough space for at least 2 full page tables and always set last_pfn to max_pfn on SI so each VM is backed by a full page table. This limits us to only 2 VMs active at any given time on SI. This will be rectified and the code can be reunified once we move to two level page tables.

Bug is not seen if pll-p value doesn't change across Sampling frequency. However on some platforms (like AM335x EVM-SK), pll-p may have different values across different sampling frequencies. In such case, above code configures the pll with a wrong value. Because of this bug, when a audio stream is played with pll value different from previous stream, audio is heard as differently(like its stretched).

The bug was introduced back in the lazy interrupt handling rework of 3.4 but was hidden until recently because hard_irq_disable did nothing. This issue will eventually appear in 3.4 stable since the hard_irq_disable fix is marked stable, so mark this one for stable too.

2d773aa Steven Rostedt 04 June 2012, 16:27:54 UTC powerpc/ftrace: Do not trace restore_interrupts() As I was adding code that affects all archs, I started testing function tracer against PPC64 and found that it currently locks up with 3.4 kernel. I figured it was due to tracing a function that shouldn't be, so I went through the following process to bisect to find the culprit: cat /debug/tracing/available_filter_functions > t num=`wc -l t` sed -ne "1,${num}p" t > t1 let num=num+1 sed -ne "${num},$p" t > t2 cat t1 > /debug/tracing/set_ftrace_filter echo function /debug/tracing/current_tracer <failed? bisect t1, if not bisect t2> It finally came down to this function: restore_interrupts() I'm not sure why this locks up the system. It just seems to prevent scheduling from occurring. Interrupts seem to still work, as I can ping the box. But all user processes freeze. When restore_interrupts() is not traced, function tracing works fine.

However, in the preempt case, we do a convoluted trick to test SIGPENDING only if PR was set and always test NEED_RESCHED ... but we forget to test any other bit of _TIF_USER_WORK_MASK !!! So that means that with preempt, we completely fail to test for things like single step, syscall tracing, etc... This should be fixed as the following path: - Test PR. If not set, go to resume_kernel, else continue. - If go resume_kernel, to do that original do_work. - If else, then always test for _TIF_USER_WORK_MASK to decide to do that original user_work, else restore directly.

The code results however in a different behaviour: it returns an error if the driver doesn't support the status operation. This is not according to the API that says that when we don't support the status operation, that we just should return a 0 value. Only when the device isn't there anymore, we should return an error.

As the lpc_ich driver now creates a platform device, auto-loading can easily be done by having a respective module alias in place.
