Clock Tree - Part 1) the MLB clock is directly feed by the AXI_CLK_ROOT. This is called 'axi' in our code. Note that the clock of the MLB IP block on the i.MX6 is completely independent of the PLL8 (MLB PLL). The MLB PLL isn't responsible for feeding the MLB IP block with a clock. Instead, it's used internally by the MLB module to sync the bus clock in case the MLB 6-pin interface is enabled: MediaLB Control 0 Register, MLB150_MLBC0[5], MLBPEN: 1 MediaLB 6-pin interface enabled. MLB PLL and MLB PHY is enabled in this case. I.e. the PLL8 MLB PLL has to be handled by the MLB driver and isn't needed for clocking the MLB module itself.

In other words, the context restored was bad. This problem could also occur in the non device-tree case, however, it is much less likely because when booting without device-tree we can detect context loss via a platform specific API and so context restore is performed less often. Nevertheless we should ensure that the gpio context is initialised on the first pm-runtime resume for gpio banks that could lose their state regardless of whether we are booting with device-tree or not. The context loss count was being initialised on the first pm-runtime suspend following a resume, by populating the get_count_loss_count() function pointer after the first pm-runtime resume.

Wysocki" Date: Wed, 8 May 2013 11:55:49 +0300 Subject: [PATCH 025/368] ACPI / LPSS: register clock device for Lynxpoint DMA properly The DMA controller in Lynxpoint is enumerated as a regular ACPI device now. To work properly it is using the LPSS root clock as a functional clock. That's why we have to register the clock device accordingly to the ACPI ID of the DMA controller. The acpi_lpss.c module is responsible to do the job. This patch also removes hardcoded name of the DMA device in clk-lpt.c and the name of the root clock in acpi_lpss.c. Signed-off-by: Rafael J.

Where L1_CACHE_BYTES == 256 and PAGE_SIZE == 4096, which is the case on s390, this assertion fails. The current scatter buffer size is also not a multiple of 64 or 128, which are more common cache line sizes. If we can make both the start and end of a scatter buffer cache-aligned, this will reduce the need for read-modify-write operations on inter- processor links. Fix the alignment by reducing EFX_RX_USR_BUF_SIZE to 2048 - 256 == 1792. (We could use 2048 - L1_CACHE_BYTES, but EFX_RX_USR_BUF_SIZE also affects user-level networking where a larger amount of housekeeping data may be needed. Although this version of the driver does not support user-level networking, I prefer to keep scattering behaviour consistent with the out-of-tree version.) This still doesn't fix the s390 build because like most architectures it has NET_IP_ALIGN == 2. When NET_IP_ALIGN != 0 we cannot achieve cache line alignment at either the start or end of a scatter buffer, so there is actually no point in padding the buffers to a multiple of the cache line size. All we need is 4-byte alignment of the network header, so do that. Adjust the assertions accordingly.

This mechanism is redundant with the Linux standard "default" pin configuration, see commit ab78029ecc347debbd737f06688d788bd9d60c1d "drivers/pinctrl: grab default handles from device core". This patch removes the TB10x custom mechanism in favour of the Linux standard.

This can cause a kernel panic when the entry is removed, because the event is already released. This fixes the bug by returning -EBUSY, because the reason why it fails is that the module is being removed at that time.

It is needed for the drain flow which happens once the ieee80211_sta has been freed, so keeping it in iwl_mvm_sta which is embed into ieee80211_sta is not a good idea. Also, since its purpose it to remove the STA in the fw only after all the frames for this station have exited the shared Tx queues, we need to decrement it in the reclaim flow. This flow can happen after ieee80211_sta has been removed, which means that we have no iwl_mvm_sta there. So we can't know what is the vif type. Hence, we know audit these frames for all the vif types. In order to avoid spawning sta_drained_wk all the time, we now check that we are in a flow in which draining might happen - only when mvmsta is NULL. This is better than previous code that would spawn sta_drained_wk all the time in AP mode.

This happens if GSO segmentation is done before stacked device for example. Result is we can send packets from a given TCP flow to different TX queues (if using multiqueue NICS). This generates OOO problems and spurious SACK & retransmits. Fix this by keeping socket pointer set for all segments. This means that every segment must also have a destructor, and the original gso skb truesize must be split on all segments, to keep precise sk->sk_wmem_alloc accounting.

This fixes the kernel crash observed on AM335xEVM-SK platform, where clkdiv32_ick clock is being used as a gpio debounce clock and since clkdiv32k_ick is in idle mode it leads to below crash - Crash Log: ========== [ 2.598347] Unhandled fault: external abort on non-linefetch (0x1028) at 0xfa1ac150 [ 2.606434] Internal error: : 1028 [#1] SMP ARM [ 2.611207] Modules linked in: [ 2.614449] CPU: 0 Not tainted (3.8.4-01382-g1f449cd-dirty #4) [ 2.620973] PC is at _set_gpio_debounce+0x60/0x104 [ 2.626025] LR is at clk_enable+0x30/0x3c Cc: stable@vger.kernel.org # v3.9 Signed-off-by: Vaibhav Hiremath Cc: Rajendra Nayak Acked-by: Paul Walmsley Signed-off-by: Tony Lindgren --- arch/arm/mach-omap2/cclock33xx_data.c | 26 +++++++++++++++++++++++--- 1 file changed, 23 insertions(+), 3 deletions(-) diff --git a/arch/arm/mach-omap2/cclock33xx_data.c b/arch/arm/mach-omap2/cclock33xx_data.c index 6ebc7803bc3e..af3544ce4f02 100644 --- a/arch/arm/mach-omap2/cclock33xx_data.c +++ b/arch/arm/mach-omap2/cclock33xx_data.c @@ -454,9 +454,29 @@ DEFINE_CLK_GATE(cefuse_fck, "sys_clkin_ck", &sys_clkin_ck, 0x0, */ DEFINE_CLK_FIXED_FACTOR(clkdiv32k_ck, "clk_24mhz", &clk_24mhz, 0x0, 1, 732); -DEFINE_CLK_GATE(clkdiv32k_ick, "clkdiv32k_ck", &clkdiv32k_ck, 0x0, - AM33XX_CM_PER_CLKDIV32K_CLKCTRL, AM33XX_MODULEMODE_SWCTRL_SHIFT, - 0x0, NULL); +static struct clk clkdiv32k_ick; + +static const char *clkdiv32k_ick_parent_names[] = { + "clkdiv32k_ck", +}; + +static const struct clk_ops clkdiv32k_ick_ops = { + .enable = &omap2_dflt_clk_enable, + .disable = &omap2_dflt_clk_disable, + .is_enabled = &omap2_dflt_clk_is_enabled, + .init = &omap2_init_clk_clkdm, +}; + +static struct clk_hw_omap clkdiv32k_ick_hw = { + .hw = { + .clk = &clkdiv32k_ick, + }, + .enable_reg = AM33XX_CM_PER_CLKDIV32K_CLKCTRL, + .enable_bit = AM33XX_MODULEMODE_SWCTRL_SHIFT, + .clkdm_name = "clk_24mhz_clkdm", +}; + +DEFINE_STRUCT_CLK(clkdiv32k_ick, clkdiv32k_ick_parent_names, clkdiv32k_ick_ops); /* "usbotg_fck" is an additional clock and not really a modulemode */ DEFINE_CLK_GATE(usbotg_fck, "dpll_per_ck", &dpll_per_ck, 0x0, From becdbc592580f76df58fdae14544f5db36ae05b4 Mon Sep 17 00:00:00 2001 From: Denis Efremov Date: Thu, 9 May 2013 13:19:39 +0400 Subject: [PATCH 083/368] iwlegacy: remove inline marking of EXPORT_SYMBOL functions EXPORT_SYMBOL and inline directives are contradictory to each other.

When pNFS is used and I/O has not yet gone to the data server servicing the inode, a LAYOUTGET can preceed the I/O. Unlike the async filemap_flush call, the LAYOUTGET must proceed to completion. If the state manager starts to recover data while the inode flush is sending the LAYOUTGET, a deadlock occurs as the callback service thread holds the single callback session slot until the flushing is done which blocks the state manager thread, and the state manager thread has set the session draining bit which puts the inode flush LAYOUTGET RPC to sleep on the forechannel slot table waitq. Separate the draining of the back channel from the draining of the fore channel by moving the NFS4_SESSION_DRAINING bit from session scope into the fore and back slot tables. Drain the back channel first allowing the LAYOUTGET call to proceed (and fail) so the callback service thread frees the callback slot. Then proceed with draining the forechannel.

The problem is that the futex code needs to perform certain ops (cmpxchg, set, add, or, andn, xor) atomically on user-space addresses, and M68K's lack of a futex.h causes those operations to be unsupported and disabled. This patch adds that support, but only for uniprocessor machines, which is adequate for M68K. For UP it's enough to disable preemption to ensure mutual exclusion (futexes don't need to care about other hardware agents), and the mandatory pagefault_disable() does just that. This patch is closely based on the one I co-wrote for UP ARM back in August 2008. The main change is that this patch uses the C get_user/put_user accessors instead of inline assembly code with exception table fixups. For non-MMU machines the new futex.h simply redirects to the generic futex.h, so there is no functional change for them. Tested on aranym with the glibc-2.17 test suite: no regressions, and a number of mutex/condvar test cases went from failing to succeeding (tst-mutexpi{5,5a,6,9}, tst-cond2[45], tst-robust[1-9], tst-robustpi[1-8]). Also tested with glibc-2.18 HEAD and a local glibc patch to enable PI mutexes: no regressions.

Wysocki" Date: Thu, 16 May 2013 22:29:28 +0200 Subject: [PATCH 139/368] ACPI / PM: Allow device power states to be used for CONFIG_PM unset Currently, drivers/acpi/device_pm.c depends on CONFIG_PM and all of the functions defined in there are replaced with static inline stubs if that option is unset. However, CONFIG_PM means, roughly, "runtime PM or suspend/hibernation support" and some of those functions are useful regardless of that. For example, they are used by the ACPI fan driver for controlling fans and acpi_device_set_power() is called during device removal. Moreover, device initialization may depend on setting device power states properly. For these reasons, make the routines manipulating ACPI device power states defined in drivers/acpi/device_pm.c available for CONFIG_PM unset too.

All the pages of the vmas belonging to the task's address space are then walked with this lock held. If a gate_vma is present in the architecture, it too is examined by the fs/proc/task_mmu.c code. As gate_vma doesn't belong to the address space of the task though, its pages are not walked. A recent cleanup (commit f6604efe) of the gate_vma initialisation code set the vm_mm value to &init_mm. Unfortunately a non-NULL vm_mm value in the gate_vma will cause the task_mmu code to attempt to walk the pages of the gate_vma (with no mmap-sem lock held). If one enables Transparent Huge Page support and vm debugging, this will then cause OOPses as pmd_trans_huge_lock is called without mmap_sem being locked.

Move the tg3_poll_fw() up to before we write to the GRC_MODE register after reset. Signed-off-by: Nithin Nayak Sujir Signed-off-by: Michael Chan Signed-off-by: David S.

This caused a tricky race condition observed with uClibc buffered file read and UNIX pipes. 1. Read access to an anon mapped page in libc .bss: write-protected zero_page mapped: TLB Entry installed with Ur + K[rwx] 2. grep calls libc:getc() -> buffered read layer calls read(2) with the internal read buffer in same .bss page. The read() call is on STDIN which has been redirected to a pipe. read(2) => sys_read() => pipe_read() => copy_to_user() 3. Since page has Kernel-write permission (despite being user-mode write-protected), copy_to_user() suceeds w/o taking a MMU TLB-Miss Exception (page-fault for ARC). core-MM is unaware that kernel erroneously wrote to the reserved read-only zero-page (BUG #1) 4. Control returns to userspace which now does a write to same .bss page Since Linux MM is not aware that page has been modified by kernel, it simply reassigns a new writable zero-init page to mapping, loosing the prior write by kernel - effectively zero'ing out the libc read buffer under the hood - hence grep doesn't see right data (BUG #2) The fix is to make all kernel-mode access permissions mirror the user-mode ones. Note that the kernel still has full access to pages, when accessed directly (w/o MMU) - this fix ensures that kernel-mode access in copy_to_from() path uses the same faulting access model as for pure user accesses to keep MM fully aware of page state. The issue is peudo-random because it only shows up if the TLB entry installed in #1 is present at the time of #3. If it is evicted out, due to TLB pressure or some-such, then copy_to_user() does take a TLB Miss Exception, with a routine write-to-anon COW processing installing a fresh page for kernel writes and also usable as it is in userspace. Further the issue was dormant for so long as it depends on where the libc internal read buffer (in .bss) is mapped at runtime. If it happens to reside in file-backed data mapping of libc (in the page-aligned slack space trailing the file backed data), loader zero padding the slack space, does the early cow page replacement, setting things up at the very beginning itself. With gcc 4.8 based builds, the libc buffer got pushed out to a real anon mapping which triggers the issue.

This patch is a fix for a bug triggering newly_acked_sacked < 0 in tcp_ack(.). The bug is triggered by sacked_out decreasing relative to prior_sacked, but packets_out remaining the same as pior_packets. This is because the snapshot of prior_packets is taken after tcp_sacktag_write_queue() while prior_sacked is captured before tcp_sacktag_write_queue(). The problem is: tcp_sacktag_write_queue (tcp_match_skb_to_sack() -> tcp_fragment) adjusts the pcount for packets_out and sacked_out (MSS change or other reason). As a result, this delta in pcount is reflected in (prior_sacked - sacked_out) but not in (prior_packets - packets_out). This patch does the following: 1) initializes prior_packets at the start of tcp_ack() so as to capture the delta in packets_out created by tcp_fragment. 2) introduces a new "previous_packets_out" variable that snapshots packets_out right before tcp_clean_rtx_queue, so pkts_acked can be correctly computed as before. 3) Computes pkts_acked using previous_packets_out, and computes newly_acked_sacked using prior_packets.

This is caused by the fact that omapdss+DT is not yet supported, and thus omapdss is not probed at all. On the other hand, omapfb is always probed. When omapfb tries to use omapdss, there's a NULL pointer dereference crash. The same error should most likely happen with omapdrm and omap_vout also. To fix this, add an "initialized" state to omapdss. When omapdss has been probed, it's marked as initialized. omapfb, omapdrm and omap_vout check this state when they are probed to see that omapdss is actually there.

The nop tracer is just a stub tracer that is used to have no tracer enabled. It is assigned at early bootup as it is the default tracer. But if ftrace=nop is on the kernel command line, the registering of the nop tracer will call tracing_set_tracer() which will try to execute the nop tracer. But it expects tr->current_trace to be assigned something as it usually is assigned to the nop tracer. As it hasn't been assigned to anything yet, it causes the system to crash. The simple fix is to move the tr->current_trace = nop before registering the nop tracer. The functionality is still the same as the nop tracer doesn't do anything anyway.

By comparing the desc_type field, it determines whether there is a nic descriptor in the array or not. In the case of no nic descriptor, this function should return NULL. The code may return an invalide descriptor, when there is no nic descriptor in the array and the desc_count is less than MAX_RESOURCE_DESC. In this case, even there is no nic descriptor, it will still return the lase descriptor since the i doesn't equal to MAX_RESOURCE_DESC. This patch fix this issue by returning the descriptor when find it and return NULL for other cases.

Added the cra_alignmask field for CBC and ECB modes. Fixed a bug in GCM where AES block size was being used instead of authsize. Removed use of blkcipher_walk routines for scatterlist processing. Corner cases in the code prevent us from processing an entire scatterlist at a time and walking the buffers in block sized chunks turns out to be unecessary anyway. Fixed off-by-one error in saving off extra data in the sha code. Fixed accounting error for number of bytes processed in the sha code.

That way, the bitmaps are more tightly packed together, and there are fewer spans of free blocks for in-use block reservations. This means it takes less time to find a free span of blocks in the bitmap, which speeds things up. This increases the performance of some workloads by almost 2X.

They are currently not reentrant in that they save register context before the stack is set or adjusted. I have observed a number of system crashes where there was clear evidence of stack corruption during interrupt processing, and as a result register corruption. Some interruptions can still occur during interruption processing, however external interrupts are disabled and data TLB misses don't occur for absolute accesses. So, it's not entirely clear what triggers this issue. Also, if an interruption occurs when Q=0, it is generally not possible to recover as the shadowed registers are not copied. The attached patch reworks the get_stack_use_cr30 and get_stack_use_r30 macros to allocate stack before doing register saves. The new code is a couple of instructions shorter than the old implementation. Thus, it's an improvement even if it doesn't fully resolve the stack corruption issue. Based on limited testing, it improves SMP system stability.

The fault dates back to the change in the writeback data integrity algorithm that uses a mark-and-sweep approach to avoid data writeback livelocks. Unfortunately, a side effect of this mark-and-sweep approach is that each page will only be written once for a data integrity sync, and there is a condition in writeback in XFS where a page may require two writeback attempts to be fully written. As a result of the high level change, we now only get a partial page writeback during the integrity sync because the first pass through writeback clears the mark left on the page index to tell writeback that the page needs writeback.... The cause is writing a partial page in the clustering code. This can happen when a mapping boundary falls in the middle of a page - we end up writing back the first part of the page that the mapping covers, but then never revisit the page to have the remainder mapped and written. The fix is simple - if the mapping boundary falls inside a page, then simple abort clustering without touching the page. This means that the next ->writepage entry that write_cache_pages() will make is the page we aborted on, and xfs_vm_writepage() will map all sections of the page correctly. This behaviour is also optimal for non-data integrity writes, as it results in contiguous sequential writeback of the file rather than missing small holes and having to write them a "random" writes in a future pass. With this fix, all the fsx tests in xfstests now pass on a 512 byte block size filesystem on a 4k page machine.

Hence the mask will always mask off the upper 32 bits of the offset and lead to incorrect writeback and invalidation ranges. This is not actually exposed as a bug because we writeback and invalidate from the rounded offset to the end of the file, and hence the offset we are actually punching a hole out of will always be covered by the code. This needs fixing, however, if we ever want to use exact ranges for writeback/invalidation here...

The following set of patches is intended to simplify process of introduction of new RapidIO fabric enumeration/discovery methods. The first patch offers ability to add new RapidIO enumeration/discovery methods using kernel configuration options. This new configuration option mechanism allows to select statically linked or modular enumeration/discovery method(s) from the list of existing methods or use external module(s). This patch also updates the currently existing enumeration/discovery code to be used as a statically linked or modular method. The corresponding configuration option is named "Basic enumeration/discovery" method. This is the only one configuration option available today but new methods are expected to be introduced after adoption of provided patches. The second patch address a long time complaint of RapidIO subsystem users regarding fabric enumeration/discovery start sequence. Existing implementation offers only a boot-time enumeration/discovery start which requires synchronized boot of all endpoints in RapidIO network. While it works for small closed configurations with limited number of endpoints, using this approach in systems with large number of endpoints is quite challenging. To eliminate requirement for synchronized start the second patch introduces RapidIO enumeration/discovery start from user space. For compatibility with the existing RapidIO subsystem implementation, automatic boot time enumeration/discovery start can be configured in by specifying "rio-scan.scan=1" command line parameter if statically linked basic enumeration method is selected. This patch: Rework to implement RapidIO enumeration/discovery method selection combined with ability to use enumeration/discovery as a kernel module. This patch adds ability to introduce new RapidIO enumeration/discovery methods using kernel configuration options. Configuration option mechanism allows to select statically linked or modular enumeration/discovery method from the list of existing methods or use external modules. If a modular enumeration/discovery is selected each RapidIO mport device can have its own method attached to it. The existing enumeration/discovery code was updated to be used as statically linked or modular method. This configuration option is named "Basic enumeration/discovery" method. Several common routines have been moved from rio-scan.c to make them available to other enumeration methods and reduce number of exported symbols.

If the wake-up handler is delayed enough, the time remaining until timeout will be calculated as 0 - and passed back as a return value - even if the condition became true before the timeout has passed. Fix this by returning at least 1 if the condition becomes true. This semantic is in line with what wait_for_condition_timeout() does; see commit bb10ed09 ("sched: fix wait_for_completion_timeout() spurious failure under heavy load"). Daniel said "We have 3 instances of this bug in drm/i915. One case even where we switch between the interruptible and not interruptible wait_event_timeout variants, foolishly presuming they have the same semantics. I very much like this."

Since hlist_for_each_entry_rcu() is changed now, we can not revert that patch directly, so this patch reverts the commit and simply fix the bug spotted by that patch This bug spotted by commit 751efd8610d3 is: There is a race condition between mmu_notifier_unregister() and __mmu_notifier_release(). Assume two tasks, one calling mmu_notifier_unregister() as a result of a filp_close() ->flush() callout (task A), and the other calling mmu_notifier_release() from an mmput() (task B). A B t1 srcu_read_lock() t2 if (!hlist_unhashed()) t3 srcu_read_unlock() t4 srcu_read_lock() t5 hlist_del_init_rcu() t6 synchronize_srcu() t7 srcu_read_unlock() t8 hlist_del_rcu() <--- NULL pointer deref. This can be fixed by using hlist_del_init_rcu instead of hlist_del_rcu. The another issue spotted in the commit is "multiple ->release() callouts", we needn't care it too much because it is really rare (e.g, can not happen on kvm since mmu-notify is unregistered after exit_mmap()) and the later call of multiple ->release should be fast since all the pages have already been released by the first call. Anyway, this issue should be fixed in a separate patch. -stable suggestions: Any version that has commit 751efd8610d3 need to be backported. I find the oldest version has this commit is 3.0-stable.

This is useful in cases where a bootloader exists and has set up the display hardware, but a Linux driver doesn't yet exist for the display hardware. Examples use-cases include: * The built-in LCD panels on the Samsung ARM chromebook, and Tegra devices, and likely many other ARM or embedded systems. These cannot yet be supported using a full graphics driver, since the panel control should be provided by the CDF (Common Display Framework), which has been stuck in design/review for quite some time. One could support these panels using custom SoC-specific code, but there is a desire to use common infra-structure rather than having each SoC vendor invent their own code, hence the desire to wait for CDF. * Hardware for which a full graphics driver is not yet available, and the path to obtain one upstream isn't yet clear. For example, the Raspberry Pi. * Any hardware in early stages of upstreaming, before a full graphics driver has been tackled. This driver can provide a graphical boot console (even full X support) much earlier in the upstreaming process, thus making new SoC or board support more generally useful earlier.

An uncharge after the last page table reference to the page goes away can race with reclaim adding the page to swap cache. Swap cache pages are usually uncharged when they are freed after swapout, from a path that also handles swap usage accounting and memcg lifetime management. However, since the last page table reference is gone and thus no references to the swap slot left, the swap slot will be freed shortly when reclaim attempts to write the page to disk. The whole swap accounting is not even necessary. So while the race condition for which this VM_BUG_ON was added is real and actually existed all along, there are no negative effects.

Typical indication of lost MSI interrupts are stalled message and doorbell transfers between RapidIO endpoints. To avoid loss of MSI interrupts all interrupts from the device must be disabled on entering the interrupt handler routine and re-enabled when exiting it. Re-enabling device interrupts will trigger new MSI message(s) if Tsi721 registered new events since entering interrupt handler routine. This patch is applicable to kernel versions starting from v3.2.

Using flush_cache_page(vma, addr, pfn) is justified only if the page is already placed in process page table, and that is done right after flush_cache_page(). But without it the arch function has no knowledge of process PTE and does nothing. Besides that, flush_cache_page() flushes an application cache page, but the kernel has a different page virtual address and dirtied it. Replace it with flush_dcache_page(new) which is the proper usage. The old page is flushed in try_to_unmap_one() before migration. This bug takes place in Sead3 board with M14Kc MIPS CPU without cache aliasing (but Harvard arch - separate I and D cache) in tight memory environment (128MB) each 1-3days on SOAK test. It fails in cc1 during kernel build (SIGILL, SIGBUS, SIGSEG) if CONFIG_COMPACTION is switched ON.

The issue was reported by Anthony Doggett : "The machine I've been trialling nilfs on is running Debian Testing, Linux version 3.2.0-4-686-pae (debian-kernel@lists.debian.org) (gcc version 4.6.3 (Debian 4.6.3-14) ) #1 SMP Debian 3.2.35-2), but I've also reproduced it (identically) with Debian Unstable amd64 and Debian Experimental (using the 3.8-trunk kernel). The problematic partitions were formatted with "mkfs.nilfs2 -b 1024 -B 8192"." SYMPTOMS: (1) System log contains error messages likewise: [63102.496756] nilfs_direct_assign: invalid pointer: 0 [63102.496786] NILFS error (device dm-17): nilfs_bmap_assign: broken bmap (inode number=28) [63102.496798] [63102.524403] Remounting filesystem read-only (2) The NILFS2 file system is remounted in RO mode. REPRODUSING PATH: (1) Create volume group with name "unencrypted" by means of vgcreate utility. (2) Run script (prepared by Anthony Doggett ): ----------------[BEGIN SCRIPT]-------------------- VG=unencrypted lvcreate --size 2G --name ntest $VG mkfs.nilfs2 -b 1024 -B 8192 /dev/mapper/$VG-ntest mkdir /var/tmp/n mkdir /var/tmp/n/ntest mount /dev/mapper/$VG-ntest /var/tmp/n/ntest mkdir /var/tmp/n/ntest/thedir cd /var/tmp/n/ntest/thedir sleep 2 date darcs init sleep 2 dmesg|tail -n 5 date darcs whatsnew || true date sleep 2 dmesg|tail -n 5 ----------------[END SCRIPT]-------------------- REPRODUCIBILITY: 100% INVESTIGATION: As it was discovered, the issue takes place during segment construction after executing such sequence of user-space operations: open("_darcs/index", O_RDWR|O_CREAT|O_NOCTTY, 0666) = 7 fstat(7, {st_mode=S_IFREG|0644, st_size=0, ...}) = 0 ftruncate(7, 60) The error message "NILFS error (device dm-17): nilfs_bmap_assign: broken bmap (inode number=28)" takes place because of trying to get block number for third block of the file with logical offset #3072 bytes. As it is possible to see from above output, the file has 60 bytes of the whole size. So, it is enough one block (1 KB in size) allocation for the whole file. Trying to operate with several blocks instead of one takes place because of discovering several dirty buffers for this file in nilfs_segctor_scan_file() method. The root cause of this issue is in nilfs_set_page_dirty function which is called just before writing to an mmapped page. When nilfs_page_mkwrite function handles a page at EOF boundary, it fills hole blocks only inside EOF through __block_page_mkwrite(). The __block_page_mkwrite() function calls set_page_dirty() after filling hole blocks, thus nilfs_set_page_dirty function (= a_ops->set_page_dirty) is called. However, the current implementation of nilfs_set_page_dirty() wrongly marks all buffers dirty even for page at EOF boundary. As a result, buffers outside EOF are inconsistently marked dirty and queued for write even though they are not mapped with nilfs_get_block function. FIX: This modifies nilfs_set_page_dirty() not to mark hole blocks dirty. Thanks to Vyacheslav Dubeyko for his effort on analysis and proposals for this issue.

Unfortuantely, it did so in a way that can lead to multiple threads all incrementing nbytes, but only one actually doing anything with the extra data, which leads to some fun random corruption and panics. The fix is to simply do everything needed to prime last_data in a single shot, so there's no window for multiple cpus to increment nbytes -- in fact, we won't even increment or decrement nbytes anymore, we'll just extract the needed EXTRACT_SIZE one time per pool and then carry on with the normal routine. All these changes have been tested across multiple hosts and architectures where panics were previously encoutered. The code changes are are strictly limited to areas only touched when when booted in fips mode. This change should also go into 3.8-stable, to make the myriads of fips users on 3.8.x happy.

That commit removed r->lock serialization between crediting entropy bits from IRQ context and accounting when extracting entropy on userspace read path, but didn't turn the r->entropy_count reads/updates in account() to use cmpxchg as well. It has been observed, that under certain circumstances this leads to read() on /dev/urandom to return 0 (EOF), as r->entropy_count gets corrupted and becomes negative, which in turn results in propagating 0 all the way from account() to the actual read() call. Convert the accounting code to be the proper lockless counterpart of what has been partially done by 902c098a3663.

It happened in-house when a benchmarker was trying to decipher the memory layout of his program. /proc//smaps and similar walks through a user page table should not be looking at VM_PFNMAP areas. Certain tests in walk_page_range() (specifically split_huge_page_pmd()) assume that all the mapped PFN's are backed with page structures. And this is not usually true for VM_PFNMAP areas. This can result in panics on kernel page faults when attempting to address those page structures. There are a half dozen callers of walk_page_range() that walk through a task's entire page table (as N. Horiguchi pointed out). So rather than change all of them, this patch changes just walk_page_range() to ignore VM_PFNMAP areas. The logic of hugetlb_vma() is moved back into walk_page_range(), as we want to test any vma in the range.

It must check which of the sleeping tasks can proceed. do_smart_update_queue() missed a few wakeups: - if a sleeping complex op was completed, then all per-semaphore queues must be scanned - not only those that were modified by *sops - if a sleeping simple op proceeded, then the global queue must be scanned again And: - the test for "|sops == NULL) before scanning the global queue is not required: If the global queue is empty, then it doesn't need to be scanned - regardless of the reason for calling do_smart_update_queue() The patch is not optimized, i.e. even completing a wait-for-zero operation causes a rescan.

As these implementations align the stack pointer to 16 bytes, this corruption did not happen every time. Patch corrects this issue.

And commit 8170e6bed465b4b0c7687f93e9948aca4358a33b x86, 64bit: Use a #PF handler to materialize early mappings on demand said: During the switchover in head_64.S, before #PF handler is available, we use three pages to handle kernel crossing 1G, 512G boundaries with sharing page by playing games with page aliasing: the same page is mapped twice in the higher-level tables with appropriate wraparound. But from the switchover code, when we set up the PUD table: 114 addq $4096, %rdx 115 movq %rdi, %rax 116 shrq $PUD_SHIFT, %rax 117 andl $(PTRS_PER_PUD-1), %eax 118 movq %rdx, (4096+0)(%rbx,%rax,8) 119 movq %rdx, (4096+8)(%rbx,%rax,8) It seems line 119 has a potential bug there. For example, if the kernel is loaded at physical address 511G+1008M, that is 000000000 111111111 111111000 000000000000000000000 and the kernel _end is 512G+2M, that is 000000001 000000000 000000001 000000000000000000000 So in this example, when using the 2nd page to setup PUD (line 114~119), rax is 511. In line 118, we put rdx which is the address of the PMD page (the 3rd page) into entry 511 of the PUD table. But in line 119, the entry we calculate from (4096+8)(%rbx,%rax,8) has exceeded the PUD page. IMO, the entry in line 119 should be wraparound into entry 0 of the PUD table. The patch fixes the bug.

The original commit was done under the incorrect assumption that it's safe to walk se_sess->sess_cmd_list unprotected in target_wait_for_sess_cmds() after sess->sess_tearing_down = 1 has been set by target_sess_cmd_list_set_waiting() during session shutdown. So instead of adding sess->sess_cmd_lock protection around sess->sess_cmd_list during target_wait_for_sess_cmds(), switch back to sess->sess_wait_list to allow wait_for_completion() + TFO->release_cmd() to occur without having to walk ->sess_cmd_list after the list_splice. Also add a check to exit if target_sess_cmd_list_set_waiting() has already been called, and add a WARN_ON to check for any fabric bug where new se_cmds are added to sess->sess_cmd_list after sess->sess_tearing_down = 1 has already been set.

The warning showed up because cper_print_pcie() is called in an interrupt context and pci_get* functions are not supposed to be called in that context.

Commit 4580a92d44 "NFS: Use server-recommended security flavor by default (NFSv3)" introduced a behavior regression for NFS mounts done via a legacy binary mount(2) call. Ensure that a default security flavor is specified for legacy binary mount requests, since they do not invoke nfs_select_flavor() in the kernel. Busybox uses klibc's nfsmount command, which performs NFS mounts using the legacy binary mount data format. /sbin/mount.nfs is not affected by this regression. Reported-by: Darrick J.

And, of course, it turns out that the above commit didn't actually fix anything - it just ensured that log recovery is guaranteed to fail when this situation occurs. And now for the gory details. xfstest xfs/085 is failing with this assert: XFS (vdb): bad number of regions (0) in inode log format XFS: Assertion failed: 0, file: fs/xfs/xfs_log_recover.c, line: 1583 Largely undocumented factoid #1: Log recovery depends on all log buffer format items starting with this format: struct foo_log_format { __uint16_t type; __uint16_t size; .... As recoery uses the size field and assumptions about 32 bit alignment in decoding format items. So don't pay much attention to the fact log recovery thinks that it decoding an inode log format item - it just uses them to determine what the size of the item is. But why would it see a log format item with a zero size? Well, luckily enough xfs_logprint uses the same code and gives the same error, so with a bit of gdb magic, it turns out that it isn't a log format that is being decoded. What logprint tells us is this: Oper (130): tid: a0375e1a len: 28 clientid: TRANS flags: none BUF: #regs: 2 start blkno: 144 (0x90) len: 16 bmap size: 2 flags: 0x4000 Oper (131): tid: a0375e1a len: 4096 clientid: TRANS flags: none BUF DATA ---------------------------------------------------------------------------- Oper (132): tid: a0375e1a len: 4096 clientid: TRANS flags: none xfs_logprint: unknown log operation type (4e49) ********************************************************************** * ERROR: data block=2 * ********************************************************************** That we've got a buffer format item (oper 130) that has two regions; the format item itself and one dirty region. The subsequent region after the buffer format item and it's data is them what we are tripping over, and the first bytes of it at an inode magic number. Not a log opheader like there is supposed to be. That means there's a problem with the buffer format item. It's dirty data region is 4096 bytes, and it contains - you guessed it - initialised inodes. But inode buffers are 8k, not 4k, and we log them in their entirety. So something is wrong here. The buffer format item contains: (gdb) p /x *(struct xfs_buf_log_format *)in_f $22 = {blf_type = 0x123c, blf_size = 0x2, blf_flags = 0x4000, blf_len = 0x10, blf_blkno = 0x90, blf_map_size = 0x2, blf_data_map = {0xffffffff, 0xffffffff, .... }} Two regions, and a signle dirty contiguous region of 64 bits. 64 * 128 = 8k, so this should be followed by a single 8k region of data. And the blf_flags tell us that the type of buffer is a XFS_BLFT_DINO_BUF. It contains inodes. And because it doesn't have the XFS_BLF_INODE_BUF flag set, that means it's an inode allocation buffer. So, it should be followed by 8k of inode data. But we know that the next region has a header of: (gdb) p /x *ohead $25 = {oh_tid = 0x1a5e37a0, oh_len = 0x100000, oh_clientid = 0x69, oh_flags = 0x0, oh_res2 = 0x0} and so be32_to_cpu(oh_len) = 0x1000 = 4096 bytes. It's simply not long enough to hold all the logged data. There must be another region. There is - there's a following opheader for another 4k of data that contains the other half of the inode cluster data - the one we assert fail on because it's not a log format header. So why is the second part of the data not being accounted to the correct buffer log format structure? It took a little more work with gdb to work out that the buffer log format structure was both expecting it to be there but hadn't accounted for it. It was at that point I went to the kernel code, as clearly this wasn't a bug in xfs_logprint and the kernel was writing bad stuff to the log. First port of call was the buffer item formatting code, and the discontiguous memory/contiguous dirty region handling code immediately stood out. I've wondered for a long time why the code had this comment in it: vecp->i_addr = xfs_buf_offset(bp, buffer_offset); vecp->i_len = nbits * XFS_BLF_CHUNK; vecp->i_type = XLOG_REG_TYPE_BCHUNK; /* * You would think we need to bump the nvecs here too, but we do not * this number is used by recovery, and it gets confused by the boundary * split here * nvecs++; */ vecp++; And it didn't account for the extra vector pointer. The case being handled here is that a contiguous dirty region lies across a boundary that cannot be memcpy()d across, and so has to be split into two separate operations for xlog_write() to perform. What this code assumes is that what is written to the log is two consecutive blocks of data that are accounted in the buf log format item as the same contiguous dirty region and so will get decoded as such by the log recovery code. The thing is, xlog_write() knows nothing about this, and so just does it's normal thing of adding an opheader for each vector. That means the 8k region gets written to the log as two separate regions of 4k each, but because nvecs has not been incremented, the buf log format item accounts for only one of them. Hence when we come to log recovery, we process the first 4k region and then expect to come across a new item that starts with a log format structure of some kind that tells us whenteh next data is going to be. Instead, we hit raw buffer data and things go bad real quick. So, the commit from 2002 that commented out nvecs++ is just plain wrong. It breaks log recovery completely, and it would seem the only reason this hasn't been since then is that we don't log large contigous regions of multi-page unmapped buffers very often. Never would be a closer estimate, at least until the CRC code came along.... So, lets fix that by restoring the nvecs accounting for the extra region when we hit this case..... .... and there's the problemin log recovery it is apparently working around: XFS: Assertion failed: i == item->ri_total, file: fs/xfs/xfs_log_recover.c, line: 2135 Yup, xlog_recover_do_reg_buffer() doesn't handle contigous dirty regions being broken up into multiple regions by the log formatting code. That's an easy fix, though - if the number of contiguous dirty bits exceeds the length of the region being copied out of the log, only account for the number of dirty bits that region covers, and then loop again and copy more from the next region. It's a 2 line fix. Now xfstests xfs/085 passes, we have one less piece of mystery code, and one more important piece of knowledge about how to structure new log format items..

This, unfortunately in no longer so simple with CRC enabled filesystems as there is owner information embedded into the BMBT blocks that are swapped between inodes. Hence swapping the forks between inodes results in the inodes having mapping blocks that point to the wrong owner and hence are considered corrupt. To fix this we need an extent tree block or record based swap algorithm so that the BMBT block owner information can be updated atomically in the swap transaction.

The write verifier fires a corruption error indicating that the block number in the header is zero. This was being tripped by xfs/110. The problem is that the initialisation of the new block is done just fine in xfs_dir3_free_get_buf(), but the caller then users a dirv2 structure to zero on-disk header fields that xfs_dir3_free_get_buf() has already zeroed. These lined up with the block number in the dir v3 header format. While looking at this, I noticed that the struct xfs_dir3_free_hdr() had 4 bytes of padding in it that wasn't defined as padding or being zeroed by the initialisation. Add a pad field declaration and fully zero the on disk and in-core headers in xfs_dir3_free_get_buf() so that this is never an issue in the future. Note that this doesn't change the on-disk layout, just makes the 32 bits of padding in the layout explicit.

Hence the mapped length ends up being too short and so we need to calculate it directly from the value length. The second is that the byte count of valid data within a buffer is capped by the length of the data and so doesn't take into account that the buffer might be longer due to headers. Hence we need to calculate the data space in the buffer first before calculating the actual byte count of data.

This, however, needs to take into account that the buffer has a header, and so the offset where zeroing starts and the length of zeroing need to take this into account. Otherwise we end up with zeros over the end of the attribute value when CRCs are enabled. While there, make sure we only ask to map an extent that covers the remaining range of the attribute, rather than asking every time for the full length of remote data. If the remote attribute blocks are contiguous with other parts of the attribute tree, it will map those blocks as well and we can potentially zero them incorrectly. We can also get buffer size mistmatches when trying to read or remove the remote attribute, and this can lead to not finding the correct buffer when looking it up in cache.

I assert that this is OK to do as CRCs are marked experimental and the first kernel it is included in has not yet reached release yet. Further, the userspace utilities are still evolving and so anyone using this stuff right now is a developer or tester using volatile filesystems for testing this feature. Hence changing the format right now to save longer term pain is the right thing to do. The fundamental change is to move from a header per extent in the attribute to a header per filesytem block in the attribute. This means there are more header blocks and the parsing of the attribute data is slightly more complex, but it has the advantage that we always know the size of the attribute on disk based on the length of the data it contains. This is where the header-per-extent method has problems. We don't know the size of the attribute on disk without first knowing how many extents are used to hold it. And we can't tell from a mapping lookup, either, because remote attributes can be allocated contiguously with other attribute blocks and so there is no obvious way of determining the actual size of the atribute on disk short of walking and mapping buffers. The problem with this approach is that if we map a buffer incorrectly (e.g. we make the last buffer for the attribute data too long), we then get buffer cache lookup failure when we map it correctly. i.e. we get a size mismatch on lookup. This is not necessarily fatal, but it's a cache coherency problem that can lead to returning the wrong data to userspace or writing the wrong data to disk. And debug kernels will assert fail if this occurs. I found lots of niggly little problems trying to fix this issue on a 4k block size filesystem, finally getting it to pass with lots of fixes. The thing is, 1024 byte filesystems still failed, and it was getting really complex handling all the corner cases that were showing up. And there were clearly more that I hadn't found yet. It is complex, fragile code, and if we don't fix it now, it will be complex, fragile code forever more. Hence the simple fix is to add a header to each filesystem block. This gives us the same relationship between the attribute data length and the number of blocks on disk as we have without CRCs - it's a linear mapping and doesn't require us to guess anything. It is simple to implement, too - the remote block count calculated at lookup time can be used by the remote attribute set/get/remove code without modification for both CRC and non-CRC filesystems. The world becomes sane again. Because the copy-in and copy-out now need to iterate over each filesystem block, I moved them into helper functions so we separate the block mapping and buffer manupulations from the attribute data and CRC header manipulations. The code becomes much clearer as a result, and it is a lot easier to understand and debug.

With eagerfpu=off FPU use is possible in those contexts. This is because of the eagerfpu check in interrupted_kernel_fpu_idle(): ... * For now, with eagerfpu we will return interrupted kernel FPU * state as not-idle.

Once it has been the __thread_has_fpu() will start returning 0. Notice that with eagerfpu the __thread_has_fpu is always true initially. FPU use is thus always possible no matter what task is under us, unless the state has already been saved with kernel_fpu_begin().

This patch changes iscsit_free_cmd() to invoke __iscsit_free_cmd() before transport_generic_free_cmd() -> target_put_sess_cmd(), and also avoids aquiring the per-connection queue locks for typical fast-path calls during normal ISTATE_REMOVE operation. Also update iscsit_free_cmd() usage throughout iscsi-target to use the new 'bool shutdown' parameter. This patch fixes a regression bug introduced during v3.10-rc1 in commit 3e1c81a95, that was causing the following WARNING to appear: [ 257.235153] ------------[ cut here]------------ [ 257.240314] WARNING: at kernel/softirq.c:160 local_bh_enable_ip+0x3c/0x86() [ 257.248089] Modules linked in: vhost_scsi ib_srpt ib_cm ib_sa ib_mad ib_core tcm_qla2xxx tcm_loop tcm_fc libfc iscsi_target_mod target_core_pscsi target_core_file target_core_iblock target_core_mod configfs ipv6 iscsi_tcp libiscsi_tcp libiscsi scsi_transport_iscsi loop acpi_cpufreq freq_table mperf kvm_intel kvm crc32c_intel button ehci_pci pcspkr joydev i2c_i801 microcode ext3 jbd raid10 raid456 async_pq async_xor xor async_memcpy async_raid6_recov raid6_pq async_tx raid1 raid0 linear igb hwmon i2c_algo_bit i2c_core ptp ata_piix libata qla2xxx uhci_hcd ehci_hcd mlx4_core scsi_transport_fc scsi_tgt pps_core [ 257.308748] CPU: 1 PID: 3295 Comm: iscsi_ttx Not tainted 3.10.0-rc2+ #103 [ 257.316329] Hardware name: Intel Corporation S5520HC/S5520HC, BIOS S5500.86B.01.00.0057.031020111721 03/10/2011 [ 257.327597] ffffffff814c24b7 ffff880458331b58 ffffffff8138eef2 ffff880458331b98 [ 257.335892] ffffffff8102c052 ffff880400000008 0000000000000000 ffff88085bdf0000 [ 257.344191] ffff88085bdf00d8 ffff88085bdf00e0 ffff88085bdf00f8 ffff880458331ba8 [ 257.352488] Call Trace: [ 257.355223] [] dump_stack+0x19/0x1f [ 257.360963] [] warn_slowpath_common+0x62/0x7b [ 257.367669] [] warn_slowpath_null+0x15/0x17 [ 257.374181] [] local_bh_enable_ip+0x3c/0x86 [ 257.380697] [] _raw_spin_unlock_bh+0x10/0x12 [ 257.387311] [] iscsit_free_r2ts_from_list+0x5e/0x67 [iscsi_target_mod] [ 257.396438] [] iscsit_release_cmd+0x20/0x223 [iscsi_target_mod] [ 257.404893] [] lio_release_cmd+0x3a/0x3e [iscsi_target_mod] [ 257.412964] [] target_release_cmd_kref+0x7a/0x7c [target_core_mod] [ 257.421712] [] target_put_sess_cmd+0x5f/0x7f [target_core_mod] [ 257.430071] [] transport_release_cmd+0x59/0x6f [target_core_mod] [ 257.438625] [] transport_put_cmd+0x131/0x140 [target_core_mod] [ 257.446985] [] ? transport_wait_for_tasks+0xfa/0x1d5 [target_core_mod] [ 257.456121] [] transport_generic_free_cmd+0x4e/0x52 [target_core_mod] [ 257.465159] [] ? __migrate_task+0x110/0x110 [ 257.471674] [] iscsit_free_cmd+0x46/0x55 [iscsi_target_mod] [ 257.479741] [] iscsit_immediate_queue+0x301/0x353 [iscsi_target_mod] [ 257.488683] [] iscsi_target_tx_thread+0x1c6/0x2a8 [iscsi_target_mod] [ 257.497623] [] ? wake_up_bit+0x25/0x25 [ 257.503652] [] ? iscsit_ack_from_expstatsn+0xd5/0xd5 [iscsi_target_mod] [ 257.512882] [] kthread+0xb0/0xb8 [ 257.518329] [] ? kthread_freezable_should_stop+0x60/0x60 [ 257.526105] [] ret_from_fork+0x7c/0xb0 [ 257.532133] [] ? kthread_freezable_should_stop+0x60/0x60 [ 257.539906] ---[ end trace 5520397d0f2e0800 ]--- Signed-off-by: Nicholas Bellinger --- drivers/target/iscsi/iscsi_target.c | 12 +++--- drivers/target/iscsi/iscsi_target_erl2.c | 12 +++--- drivers/target/iscsi/iscsi_target_util.c | 54 +++++++++++++++++------- drivers/target/iscsi/iscsi_target_util.h | 2 +- 4 files changed, 52 insertions(+), 28 deletions(-) diff --git a/drivers/target/iscsi/iscsi_target.c b/drivers/target/iscsi/iscsi_target.c index 262ef1f23b38..d7705e5824fb 100644 --- a/drivers/target/iscsi/iscsi_target.c +++ b/drivers/target/iscsi/iscsi_target.c @@ -651,7 +651,7 @@ static int iscsit_add_reject( cmd->buf_ptr = kmemdup(buf, ISCSI_HDR_LEN, GFP_KERNEL);

For 64 bit processes, disabled system register accesses are currently treated as unhandled instructions. This patch modifies entry.S to treat these unhandled traps as undefined instructions, sending a SIGILL to userspace. This gives processes a chance to handle this and stop using inaccessible registers, and prevents further issues in the kernel as a result of the die().

The next_pos pointer is updated but its value isn't pushed into the key used for the search itself. As a result, the search returns the same item that the last cycle of the loop did and filldir() is called multiple times with the same data. The end result is that the buffer can contain the same name multiple times. This can be returned to userspace or used internally in the xattr code where it can manifest with the following warning: jdm-20004 reiserfs_delete_xattrs: Couldn't delete all xattrs (-2) reiserfs_for_each_xattr uses reiserfs_readdir_dentry to iterate over the xattr names and ends up trying to unlink the same name twice. The second attempt fails with -ENOENT and the error is returned. At some point I'll need to add support into reiserfsck to remove the orphaned directories left behind when this occurs.

When the setuid bit is cleared during chown, ATTR_MODE and iattr->ia_mode are passed to all the xattrs as well. This means that the xattr directory will have S_IFREG added to its mode bits. This has been prevented in practice by a missing IS_PRIVATE check in reiserfs_acl_chmod, which caused a double-lock to occur while holding the write lock. Since the file system was completely locked up, the writeout of the corrupted mode never happened. This patch temporarily clears everything but ATTR_UID|ATTR_GID for the calls to reiserfs_setattr and adds the missing IS_PRIVATE check.

If one client deletes and recreates a file with timing such that the recreated file obtains the same [dirid, objectid] pair as the original file while another client accesses the file via file handle, the create and lookup can race and deadlock if the lookup manages to create the in-memory inode first. The create thread, in insert_inode_locked4, will hold the write lock while waiting on the other inode to be unlocked. The lookup thread, anywhere in the iget path, will release and reacquire the write lock while it schedules. If it needs to reacquire the lock while the create thread has it, it will never be able to make forward progress because it needs to reacquire the lock before ultimately unlocking the inode. This patch drops the write lock across the insert_inode_locked4 call so that the ordering of inode_wait -> write lock is retained. Since this would have been the case before the BKL push-down, this is safe.

It's possible that the stack has moved back up after the tbegin. The obvious case here is when the tbegin is called inside a function that returns before a tend. In this case, the stack is part of the checkpointed transactional memory state. If we write over this non transactionally or in suspend, we are in trouble because if we get a tm abort, the program counter and stack pointer will be back at the tbegin but our in memory stack won't be valid anymore. To avoid this, when taking a signal in an active transaction, we need to use the stack pointer from the checkpointed state, rather than the speculated state. This ensures that the signal context (written tm suspended) will be written below the stack required for the rollback. The transaction is aborted becuase of the treclaim, so any memory written between the tbegin and the signal will be rolled back anyway. For signals taken in non-TM or suspended mode, we use the normal/non-checkpointed stack pointer.

Only if this bit is set, it should continue with the process of calling preempt_schedule_irq() to schedule highest priority task if available. Current code assumes that r8 contains TI_FLAGS and check this for _TIF_NEED_RESCHED, but as r8 is modified in the code which executes before this check, r8 no longer contains the expected TI_FLAGS information. As a result check for comparison with _TIF_NEED_RESCHED was failing even if NEED_RESCHED bit is set in the current thread_info flag. Due to this, preempt_schedule_irq() and in turn scheduler was not getting called even if highest priority task is ready for execution. So, store temporary results in r0 instead of r8 to prevent r8 from getting modified as subsequent code is dependent on its value.

H_IPOLL returns information about the priority and pending interrupts for a virtual cpu, without changing any state. H_XIRR_X is like H_XIRR in that it reads and acknowledges the highest-priority pending interrupt, but it also returns the timestamp (timebase register value) from when the interrupt was first received by the hypervisor. Currently we just return the current time, since we don't do any software queueing of virtual interrupts inside the XICS emulation code. These hcalls are not currently used by Linux guests, but may be in future.

Looking further, the mobility code in pseries is one of the call-sites which uses rtas_ibm_suspend_me(), which in turn calls rtas_cpu_state_change_mask(). And the mobility code is unconditionally compiled-in (it does not fall under any Kconfig option). And commit 120496ac (powerpc: Bring all threads online prior to migration/hibernation) which introduced this build regression is critical for the proper functioning of the migration code. So it appears that the only solution to this problem is to enable CONFIG_HOTPLUG_CPU if SMP is enabled on PPC_PSERIES platforms. So make that change in the Kconfig.

And even worse score a SIGBUS when accessing gtt mmaps. The established ABI is that we _only_ return an -EIO from execbuf - all other ioctls should just work. And since the reset code moves all bos out of gpu domains and clears out all the last_seqno/ring tracking there really shouldn't be any reason for non-execbuf code to ever touch the hw and see an -EIO. After some extensive discussions we've noticed that these spurios -EIO are caused by i915_gem_wait_for_error: http://www.mail-archive.com/intel-gfx@lists.freedesktop.org/msg20540.html That is easy to fix by returning 0 instead of -EIO, since grabbing the dev->struct_mutex does not yet mean that we actually want to touch the hw. And so there is no reason at all to fail with -EIO. But that's not the entire since, since often (at least it's easily googleable) dmesg indicates that the reset fails and we declare the gpu wedged. Then, quite a bit later X wakes up with the "Timed out waiting for the gpu reset to complete" DRM_ERROR message in wait_for_errror and brings down the desktop with an -EIO/SIGBUS. So clearly we're missing a wakeup somewhere, since the gpu reset just doesn't take 10 seconds to complete. And indeed we're do handle the terminally wedged state wrong. Fix this all up.

Hence quirk the quirk. The problem is that crtc->active tracks the state of the entire display pipe, i.e. including planes, encoders and all. But our hw state readout simply looks at the pipe. But with the pipe A quirk we force-enable that (together with it's pll). To fix that mismatch we have two options: - Quirk the checked state to match what our sw tracking states if the pipe A quirk is in effect. - Improve the hw state readout to not get fooled by the pipe A quirk. Since we already have similar state clamping in e.g. assert_pipe I've opted for the first variant. Also note that we don't really loose any state checking: Individual pieces of the abstract crtc pipe are checked in the enable/disable functions with the various asssert_* checks we have, and the hw state check code doesn't check anything if the pipe is off anyway. v2: Pimp commit message after discussion with Chris and only apply the quirk for the quirk if we're checking pipe A. Otherwise we'll miss state checking for pipe B on i830M ... v3: Make the code comment consistent with the improved commit message, too (Chris).

This regression seems to have been introduced in commit f899fc64cda8569d0529452aafc0da31c042df2e Author: Chris Wilson Date: Tue Jul 20 15:44:45 2010 -0700 drm/i915: use GMBUS to manage i2c links Signed-off-by: Egbert Eich Cc: stable@vger.kernel.org Reviewed-by: Chris Wilson [danvet: Add note about which commit likely introduced this issue.] Signed-off-by: Daniel Vetter --- drivers/gpu/drm/i915/intel_sdvo.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/gpu/drm/i915/intel_sdvo.c b/drivers/gpu/drm/i915/intel_sdvo.c index d15428404b9a..4c47b449b775 100644 --- a/drivers/gpu/drm/i915/intel_sdvo.c +++ b/drivers/gpu/drm/i915/intel_sdvo.c @@ -1776,7 +1776,7 @@ static void intel_sdvo_get_lvds_modes(struct drm_connector *connector) * Assume that the preferred modes are * arranged in priority order. */ - intel_ddc_get_modes(connector, intel_sdvo->i2c); + intel_ddc_get_modes(connector, &intel_sdvo->ddc); if (list_empty(&connector->probed_modes) == false) goto end;
