671ee7f Liu Gang-B34182 25 August 2011, 22:59:25 UTC arch/powerpc/sysdev/fsl_rio.c: correct IECSR register clear value This bug causes the IECSR register clear failure. In this case, the RETE (retry error threshold exceeded) interrupt will be generated and cannot be cleared. So the related ISR may be called persistently. The RETE bit in IECSR is cleared by writing a 1 to it.

62d1760 MyungJoo Ham 25 August 2011, 22:59:24 UTC drivers/rtc/rtc-s3c.c: allow multiple open / allow no-ioctl-open'ed rtc to have irq. The previous rtc-s3c had two issues related with its IRQ. 1. Users cannot open rtc multiple times because an open operation calls request_irq on the same IRQ. (e.g., two user processes wants to open and read RTC time from rtc-s3c at the same time) 2. If alarm is set and no one has the rtc opened with filesystem (either the alarm is set by kernel/boot-loader or user set an alarm and closed rtc dev file), the pending bit is not cleared and no further interrupt is invoked. When the alarm is used by the system itself such as a resume from suspend-to-RAM or other Low-power modes/idle, this is a critical issue. This patch mitigates these issues by calling request_irq at probe and free_irq at remove.

23751be Johannes Weiner 25 August 2011, 22:59:16 UTC memcg: fix hierarchical oom locking Commit 79dfdaccd1d5 ("memcg: make oom_lock 0 and 1 based rather than counter") tried to oom lock the hierarchy and roll back upon encountering an already locked memcg. The code is confused when it comes to detecting a locked memcg, though, so it would fail and rollback after locking one memcg and encountering an unlocked second one. The result is that oom-locking hierarchies fails unconditionally and that every oom killer invocation simply goes to sleep on the oom waitqueue forever. The tasks practically hang forever without anyone intervening, possibly holding locks that trip up unrelated tasks, too.

284fb68 Alexandre Bounine 25 August 2011, 22:59:13 UTC rapidio: fix use of non-compatible registers Replace/remove use of RIO v.1.2 registers/bits that are not forward-compatible with newer versions of RapidIO specification. RapidIO specification v.1.3 removed Write Port CSR, Doorbell CSR, Mailbox CSR and Mailbox and Doorbell bits of the PEF CAR. Use of removed (since RIO v.1.3) register bits affects users of currently available 1.3 and 2.x compliant devices who may use not so recent kernel versions. Removing checks for unsupported bits makes corresponding routines compatible with all versions of RapidIO specification. Therefore, backporting makes stable kernel versions compliant with RIO v.1.3 and later as well.

439423f Shaohua Li 25 August 2011, 22:59:12 UTC vmscan: clear ZONE_CONGESTED for zone with good watermark ZONE_CONGESTED is only cleared in kswapd, but pages can be freed in any task. It's possible ZONE_CONGESTED isn't cleared in some cases: 1. the zone is already balanced just entering balance_pgdat() for order-0 because concurrent tasks free memory. In this case, later check will skip the zone as it's balanced so the flag isn't cleared. 2. high order balance fallbacks to order-0. quote from Mel: At the end of balance_pgdat(), kswapd uses the following logic; If reclaiming at high order { for each zone { if all_unreclaimable skip if watermark is not met order = 0 loop again /* watermark is met */ clear congested } } i.e. it clears ZONE_CONGESTED if it the zone is balanced. if not, it restarts balancing at order-0. However, if the higher zones are balanced for order-0, kswapd will miss clearing ZONE_CONGESTED as that only happens after a zone is shrunk. This can mean that wait_iff_congested() stalls unnecessarily. This patch makes kswapd clear ZONE_CONGESTED during its initial highmem->dma scan for zones that are already balanced.

4c30c6f Nishanth Aravamudan 25 August 2011, 22:59:11 UTC kernel/printk: do not turn off bootconsole in printk_late_init() if keep_bootcon It seems that 7bf693951a8e ("console: allow to retain boot console via boot option keep_bootcon") doesn't always achieve what it aims, as when printk_late_init() runs it unconditionally turns off all boot consoles. With this patch, I am able to see more messages on the boot console in KVM guests than I can without, when keep_bootcon is specified. I think it is appropriate for the relevant -stable trees. However, it's more of an annoyance than a serious bug (ideally you don't need to keep the boot console around as console handover should be working -- I was encountering a situation where the console handover wasn't working and not having the boot console available meant I couldn't see why).

If the task is migrated to a different CPU in between, noone will clear the flag on the first stock and it will be forever undrainable. Its charge can not be recovered and the cgroup can not be deleted anymore. Properly pin the task to the executing CPU while draining stocks.

e096d0c Josh Boyer 25 August 2011, 11:48:12 UTC lockdep: Add helper function for dir vs file i_mutex annotation Purely in-memory filesystems do not use the inode hash as the dcache tells us if an entry already exists. As a result, they do not call unlock_new_inode, and thus directory inodes do not get put into a different lockdep class for i_sem. We need the different lockdep classes, because the locking order for i_mutex is different for directory inodes and regular inodes. Directory inodes can do "readdir()", which takes i_mutex *before* possibly taking mm->mmap_sem (due to a page fault while copying the directory entry to user space). In contrast, regular inodes can be mmap'ed, which takes mm->mmap_sem before accessing i_mutex. The two cases can never happen for the same inode, so no real deadlock can occur, but without the different lockdep classes, lockdep cannot understand that. As a result, if CONFIG_DEBUG_LOCK_ALLOC is set, this can lead to false positives from lockdep like below: find/645 is trying to acquire lock: (&mm->mmap_sem){++++++}, at: [<ffffffff81109514>] might_fault+0x5c/0xac but task is already holding lock: (&sb->s_type->i_mutex_key#15){+.+.+.}, at: [<ffffffff81149f34>] vfs_readdir+0x5b/0xb4 which lock already depends on the new lock. the existing dependency chain (in reverse order) is: -> #1 (&sb->s_type->i_mutex_key#15){+.+.+.}: [<ffffffff8108ac26>] lock_acquire+0xbf/0x103 [<ffffffff814db822>] __mutex_lock_common+0x4c/0x361 [<ffffffff814dbc46>] mutex_lock_nested+0x40/0x45 [<ffffffff811daa87>] hugetlbfs_file_mmap+0x82/0x110 [<ffffffff81111557>] mmap_region+0x258/0x432 [<ffffffff811119dd>] do_mmap_pgoff+0x2ac/0x306 [<ffffffff81111b4f>] sys_mmap_pgoff+0x118/0x16a [<ffffffff8100c858>] sys_mmap+0x22/0x24 [<ffffffff814e3ec2>] system_call_fastpath+0x16/0x1b -> #0 (&mm->mmap_sem){++++++}: [<ffffffff8108a4bc>] __lock_acquire+0xa1a/0xcf7 [<ffffffff8108ac26>] lock_acquire+0xbf/0x103 [<ffffffff81109541>] might_fault+0x89/0xac [<ffffffff81149cff>] filldir+0x6f/0xc7 [<ffffffff811586ea>] dcache_readdir+0x67/0x205 [<ffffffff81149f54>] vfs_readdir+0x7b/0xb4 [<ffffffff8114a073>] sys_getdents+0x7e/0xd1 [<ffffffff814e3ec2>] system_call_fastpath+0x16/0x1b This patch moves the directory vs file lockdep annotation into a helper function that can be called by in-memory filesystems and has hugetlbfs call it.

be27425 Andi Kleen 19 August 2011, 23:15:10 UTC Add a personality to report 2.6.x version numbers I ran into a couple of programs which broke with the new Linux 3.0 version. Some of those were binary only. I tried to use LD_PRELOAD to work around it, but it was quite difficult and in one case impossible because of a mix of 32bit and 64bit executables. For example, all kind of management software from HP doesnt work, unless we pretend to run a 2.6 kernel. $ uname -a Linux svivoipvnx001 3.0.0-08107-g97cd98f #1062 SMP Fri Aug 12 18:11:45 CEST 2011 i686 i686 i386 GNU/Linux $ hpacucli ctrl all show Error: No controllers detected. $ rpm -qf /usr/sbin/hpacucli hpacucli-8.75-12.0 Another notable case is that Python now reports "linux3" from sys.platform(); which in turn can break things that were checking sys.platform() == "linux2": https://bugzilla.mozilla.org/show_bug.cgi?id=664564 It seems pretty clear to me though it's a bug in the apps that are using '==' instead of .startswith(), but this allows us to unbreak broken programs. This patch adds a UNAME26 personality that makes the kernel report a 2.6.40+x version number instead. The x is the x in 3.x. I know this is somewhat ugly, but I didn't find a better workaround, and compatibility to existing programs is important. Some programs also read /proc/sys/kernel/osrelease. This can be worked around in user space with mount --bind (and a mount namespace) To use: wget ftp://ftp.kernel.org/pub/linux/kernel/people/ak/uname26/uname26.c gcc -o uname26 uname26.c ./uname26 program Signed-off-by: Andi Kleen <ak@linux.intel.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> 25 August 2011, 17:17:28 UTC
caca951 Linus Torvalds 24 August 2011, 22:55:30 UTC firmware loader: allow builtin firmware load even if usermodehelper is disabled In commit a144c6a6c924 ("PM: Print a warning if firmware is requested when tasks are frozen") we not only printed a warning if somebody tried to load the firmware when tasks are frozen - we also failed the load. But that check was done before the check for built-in firmware, and then when we disallowed usermode helpers during bootup (commit 288d5abec831: "Boot up with usermodehelper disabled"), that actually means that built-in modules can no longer load their firmware even if the firmware is built in too. Which used to work, and some people depended on it for the R100 driver. So move the test for usermodehelper_is_disabled() down, to after checking the built-in firmware.

It turns out that this breaks several drivers, one example being OMAP boards which use the on-board OMAP UARTs and the omap-serial driver that will not boot to userspace after the commit. Paul Walmsley reports that enabling CONFIG_DEBUG_SHIRQ reveals 'IRQ handler type mismatch' errors: IRQ handler type mismatch for IRQ 74 current handler: serial idle ... and the reason is that setting IRQF_ONESHOT will now result in those interrupt handlers having different IRQF flags, and thus being unsharable. So the commit log in the reverted commit: "Since it is required for those users and there is no difference for others it makes sense to add this flag unconditionally." is simply not true: there may not be any difference from a "actions at irq time", but there is a *big* difference wrt this flag testing irq management (see __setup_irq() in kernel/irq/manage.c). One solution may be to stop verifying IRQF_ONESHOT in __setup_irq(), but right now the safe course of action is to revert the change. Let's revisit this in a later merge window.

These keyboards dont seem to allow the records to be initialized, and hence a timeout occurs when the usbhid driver attempts to initialize them. The patch just adds the signature for these keyboards to the hid-quirks list with the setting HID_QUIRK_NO_INIT_REPORTS. This removes the 5-10 second wait for the timeout to occur.

c3c74c7 Nicholas Bellinger 13 August 2011, 12:30:31 UTC target: Fix task SGL chaining breakage with transport_allocate_data_tasks This patch fixes two bugs associated with transport_do_task_sg_chain() operation where transport_allocate_data_tasks() was incorrectly setting task_padded_sg for all tasks, and causing bogus task->task_sg_nents assignments + OOPsen with fabrics depending upon this code. The first bit here adds a task_sg_nents_padded check in transport_allocate_data_tasks() to include an extra SGL vector when necessary for tasks that expect to be linked using sg_chain(). The second change involves making transport_do_task_sg_chain() properly account for the extra SGL vector when task->task_padded_sg is set for the non trailing ->task_sg or single ->task_sg allocations. Note this patch also removes the BUG_ON(!task->task_padded_sg) check within transport_do_task_sg_chain() as we expect this to happen normally with the updated logic in transport_allocate_data_tasks(), along with being bogus for CONTROL_SG_IO_CDB type payloads. So far this bugfix has been tested with tcm_qla2xxx and iblock backends in (task_count > 1)( and (task_count == 1) operation.

525a48a Nicholas Bellinger 13 August 2011, 09:11:38 UTC target: Fix task count > 1 handling breakage and use max_sector page alignment This patch addresses recent breakage with multiple se_task (task_count > 1) operation following backend dev->se_sub_dev->se_dev_attrib.max_sectors in new transport_allocate_data_tasks() code. The initial bug here was a bogus task->task_sg_nents assignment in transport_allocate_data_tasks() based on the passed parameter, which now uses DIV_ROUND_UP(task_size, PAGE_SIZE) to determine the proper number of per task SGL entries for the (task_count > 1) case. This also means we now need to enforce a PAGE_SIZE aligned max_sector count value for this to work as expected without bringing back the pre v3.1 transport_map_mem_to_sg() logic to handle SGL offsets across multiple tasks. So this patch adds se_dev_align_max_sectors() to round down max_sectors as necessary to ensure this alignment via se_dev_set_default_attribs() and se_dev_align_max_sectors() and keeps it simple for (task_count > 1) operation. So far this bugfix has been tested with (task_count > 1) operation using iscsi-target and iblock backends.
