c4c0e9e David Rientjes 21 June 2012, 01:00:12 UTC mm, mempolicy: fix mbind() to do synchronous migration If the range passed to mbind() is not allocated on nodes set in the nodemask, it migrates the pages to respect the constraint. The final formal of migrate_pages() is a mode of type enum migrate_mode, not a boolean. do_mbind() is currently passing "true" which is the equivalent of MIGRATE_SYNC_LIGHT. This should instead be MIGRATE_SYNC for synchronous page migration.

48c3b58 Greg Pearson 20 June 2012, 19:53:05 UTC mm/memblock: fix overlapping allocation when doubling reserved array __alloc_memory_core_early() asks memblock for a range of memory then try to reserve it. If the reserved region array lacks space for the new range, memblock_double_array() is called to allocate more space for the array. If memblock is used to allocate memory for the new array it can end up using a range that overlaps with the range originally allocated in __alloc_memory_core_early(), leading to possible data corruption. With this patch memblock_double_array() now calls memblock_find_in_range() with a narrowed candidate range (in cases where the reserved.regions array is being doubled) so any memory allocated will not overlap with the original range that was being reserved. The range is narrowed by passing in the starting address and size of the previously allocated range. Then the range above the ending address is searched and if a candidate is not found, the range below the starting address is searched.

50d75f8 Oleg Nesterov 20 June 2012, 19:53:04 UTC pidns: find_new_reaper() can no longer switch to init_pid_ns.child_reaper find_new_reaper() changes pid_ns->child_reaper, see add0d4df ("pid_ns: zap_pid_ns_processes: fix the ->child_reaper changing"). The original reason has gone away after the previous patch, ->children list must be empty after zap_pid_ns_processes(). However now we can not switch to init_pid_ns.child_reaper. __unhash_process() relies on the "->child_reaper == parent" check, but this check does not work if the last exiting task is also the child reaper. As Eric sugested, we can change __unhash_process() to use the parent's pid_ns and remove this code. Also, with this change we can move detach_pid(PIDTYPE_PID) back, where it was before the previous fix. Signed-off-by: Oleg Nesterov <oleg@redhat.com> Acked-by: "Eric W.

6347e90 Eric W. Biederman 20 June 2012, 19:53:03 UTC pidns: guarantee that the pidns init will be the last pidns process reaped Today we have a twofold bug. Sometimes release_task on pid == 1 in a pid namespace can run before other processes in a pid namespace have had release task called. With the result that pid_ns_release_proc can be called before the last proc_flus_task() is done using upid->ns->proc_mnt, resulting in the use of a stale pointer. This same set of circumstances can lead to waitpid(...) returning for a processes started with clone(CLONE_NEWPID) before the every process in the pid namespace has actually exited. To fix this modify zap_pid_ns_processess wait until all other processes in the pid namespace have exited, even EXIT_DEAD zombies. The delay_group_leader and related tests ensure that the thread gruop leader will be the last thread of a process group to be reaped, or to become EXIT_DEAD and self reap. With the change to zap_pid_ns_processes we get the guarantee that pid == 1 in a pid namespace will be the last task that release_task is called on. With pid == 1 being the last task to pass through release_task pid_ns_release_proc can no longer be called too early nor can wait return before all of the EXIT_DEAD tasks in a pid namespace have exited.

fbb24a3 Ryusuke Konishi 20 June 2012, 19:52:57 UTC nilfs2: ensure proper cache clearing for gc-inodes A gc-inode is a pseudo inode used to buffer the blocks to be moved by garbage collection. Block caches of gc-inodes must be cleared every time a garbage collection function (nilfs_clean_segments) completes. Otherwise, stale blocks buffered in the caches may be wrongly reused in successive calls of the GC function. For user files, this is not a problem because their gc-inodes are distinguished by a checkpoint number as well as an inode number. They never buffer different blocks if either an inode number, a checkpoint number, or a block offset differs. However, gc-inodes of sufile, cpfile and DAT file can store different data for the same block offset. Thus, the nilfs_clean_segments function can move incorrect block for these meta-data files if an old block is cached. I found this is really causing meta-data corruption in nilfs. This fixes the issue by ensuring cache clear of gc-inodes and resolves reported GC problems including checkpoint file corruption, b-tree corruption, and the following warning during GC. nilfs_palloc_freev: entry number 307234 already freed. ...

e4eed03 Andrea Arcangeli 20 June 2012, 19:52:57 UTC thp: avoid atomic64_read in pmd_read_atomic for 32bit PAE In the x86 32bit PAE CONFIG_TRANSPARENT_HUGEPAGE=y case while holding the mmap_sem for reading, cmpxchg8b cannot be used to read pmd contents under Xen. So instead of dealing only with "consistent" pmdvals in pmd_none_or_trans_huge_or_clear_bad() (which would be conceptually simpler) we let pmd_none_or_trans_huge_or_clear_bad() deal with pmdvals where the low 32bit and high 32bit could be inconsistent (to avoid having to use cmpxchg8b). The only guarantee we get from pmd_read_atomic is that if the low part of the pmd was found null, the high part will be null too (so the pmd will be considered unstable). And if the low part of the pmd is found "stable" later, then it means the whole pmd was read atomically (because after a pmd is stable, neither MADV_DONTNEED nor page faults can alter it anymore, and we read the high part after the low part). In the 32bit PAE x86 case, it is enough to read the low part of the pmdval atomically to declare the pmd as "stable" and that's true for THP and no THP, furthermore in the THP case we also have a barrier() that will prevent any inconsistent pmdvals to be cached by a later re-read of the *pmd.

abca7c4 Pravin B Shelar 20 June 2012, 19:52:56 UTC mm: fix slab->page _count corruption when using slub On arches that do not support this_cpu_cmpxchg_double() slab_lock is used to do atomic cmpxchg() on double word which contains page->_count. The page count can be changed from get_page() or put_page() without taking slab_lock. That corrupts page counter. Fix it by moving page->_count out of cmpxchg_double data. So that slub does no change it while updating slub meta-data in struct page.

b4a91cf Dylan Reid 16 June 2012, 02:36:23 UTC ALSA: hda - Handle open while transitioning to D3. This addresses an issue encountered when a pcm is opened while transitioning to low power state (codec->power_on == 1 && codec->power_transition == -1). Add snd_pcm_power_up_d3wait to hda_codec. This function is used to power up from azx_open as opposed to snd_hda_power_up used from codec_exec_verb. When powering up from azx_open, wait for pending power downs to complete, avoiding the power up continuing in parallel with the power down on the work queue. The specific issue seen was with the CS4210 codec, it powers off the ADC and DAC nid in its suspend handler. If it is re-opened before the ~100ms power down process completes, the ADC and DAC nid are initialized while powered down and audio is lost until another suspend/resume cycle.

128789a Andrew Lunn 13 June 2012, 12:52:45 UTC ARM: Kirkwood: Fix clk problems modular ethernet driver When the ethernet driver was built as a module, it would lock the machine when loaded. At boot the ethernet clks are unused, so get turned off. Later, when the module is loaded, the probe function would access the hardware before the clock was restarted, and the machine would lock. It has also been determined that when the clk is turned off, the interface forgets its MAC address, which for most systems, is set by the boot loader. When the machine setup file creates a platform device for the interface, prepare and enable the clock for the interface. This will ensure it is not turned off. However, if the setup file only instantiates one platform device, the other will have its clk disabled, thus maybe saving a little power.

9b0f7e3 Arnd Bergmann 11 June 2012, 14:03:58 UTC arm: versatile: fix and enable PCI I/O space With commit 4d5fc58dbe34b (ARM: remove bunch of now unused mach/io.h files), the I/O space setup was completely broken on versatile. This patch fixes that and prepares for further I/O space clean-up. I/O space handling on the versatile platform is currently broken in multiple ways. Most importantly, the ports do not get mapped into the virtual address space at all. Also, there is some amount of confusion between PCI I/O space and other statically mapped MMIO registers in the platform code: * The __io_address() macro that is used to access the platform register maps to the same __io macro that gets used for I/O space. * The IO_SPACE_LIMIT is set to a value that is much larger than the total available space. * The I/O resource of the PCI bus is set to the physical address of the mapping, which is way outside of the actual I/O space limit as well as the address range that gets decoded by traditional PCI cards. * No attempt is made to stay outside of the ISA port range that some device drivers try access. * No resource gets requested as a child of ioport_resource, but an IORESOURCE_IO type mapping gets requested as a child of iomem_resource. This patch attempts to correct all of the above. This makes it possible to use virtio-pci based virtual devices as well as actual PCI cards including those with legacy ISA port ranges like VGA. Some of the issues seem to be duplicated on other platforms.

4a77a5a Yuanhan Liu 16 June 2012, 13:21:51 UTC printk: use mutex lock to stop syslog_seq from going wild Although syslog_seq and log_next_seq stuff are protected by logbuf_lock spin log, it's not enough. Say we have two processes A and B, and let syslog_seq = N, while log_next_seq = N + 1, and the two processes both come to syslog_print at almost the same time. And No matter which process get the spin lock first, it will increase syslog_seq by one, then release spin lock; thus later, another process increase syslog_seq by one again. In this case, syslog_seq is bigger than syslog_next_seq. And latter, it would make: wait_event_interruptiable(log_wait, syslog != log_next_seq) don't wait any more even there is no new write comes. Thus it introduce a infinite loop reading. I can easily see this kind of issue by the following steps: # cat /proc/kmsg # at meantime, I don't kill rsyslog # So they are the two processes. # xinit # I added drm.debug=6 in the kernel parameter line, # so that it will produce lots of message and let that # issue happen It's 100% reproducable on my side. And my disk will be filled up by /var/log/messages in a quite short time. So, introduce a mutex_lock to stop syslog_seq from going wild just like what devkmsg_read() does.

9b15b81 Hugh Dickins 16 June 2012, 00:55:50 UTC swap: fix shmem swapping when more than 8 areas Minchan Kim reports that when a system has many swap areas, and tmpfs swaps out to the ninth or more, shmem_getpage_gfp()'s attempts to read back the page cannot locate it, and the read fails with -ENOMEM. Whoops. Yes, I blindly followed read_swap_header()'s pte_to_swp_entry( swp_entry_to_pte()) technique for determining maximum usable swap offset, without stopping to realize that that actually depends upon the pte swap encoding shifting swap offset to the higher bits and truncating it there. Whereas our radix_tree swap encoding leaves offset in the lower bits: it's swap "type" (that is, index of swap area) that was truncated. Fix it by reducing the SWP_TYPE_SHIFT() in swapops.h, and removing the broken radix_to_swp_entry(swp_to_radix_entry()) from read_swap_header(). This does not reduce the usable size of a swap area any further, it leaves it as claimed when making the original commit: no change from 3.0 on x86_64, nor on i386 without PAE; but 3.0's 512GB is reduced to 128GB per swapfile on i386 with PAE. It's not a change I would have risked five years ago, but with x86_64 supported for ten years, I believe it's appropriate now. Hmm, and what if some architecture implements its swap pte with offset encoded below type? That would equally break the maximum usable swap offset check. Happily, they all follow the same tradition of encoding offset above type, but I'll prepare a check on that for next.
