2014-09-10pnfs: fix filelayout_retry_commit when idx > 0Weston Andros Adamson
filelayout_retry_commit was recently split out from alloc_ds_commits, but was done in such a way that the bucket pointer always starts at index 0 no matter what the @idx argument is set to. The intention of the @idx argument is to retry commits starting at bucket @idx. This is called when alloc_ds_commits fails for a bucket.

When running a 32-bit inputattach utility in a 64-bit system, there will be error code "inputattach: can't set device type". This is caused by the serport device driver not supporting compat_ioctl, so that SPIOCSTYPE ioctl fails.

2014-09-10libceph: do not hard code max auth ticket lenIlya Dryomov
We hard code cephx auth ticket buffer size to 256 bytes. This isn't enough for any moderate setups and, in case tickets themselves are not encrypted, leads to buffer overflows (ceph_x_decrypt() errors out, but ceph_decode_copy() doesn't - it's just a memcpy() wrapper). Since the buffer is allocated dynamically anyway, allocated it a bit later, at the point where we know how much is going to be needed.

2014-09-10dm cache: fix race causing dirty blocks to be marked as cleanAnssi Hannula
When a writeback or a promotion of a block is completed, the cell of that block is removed from the prison, the block is marked as clean, and the clear_dirty() callback of the cache policy is called. Unfortunately, performing those actions in this order allows an incoming new write bio for that block to come in before clearing the dirty status is completed and therefore possibly causing one of these two scenarios: Scenario A: Thread 1 Thread 2 cell_defer() . - cell removed from prison . - detained bios queued . . incoming write bio . remapped to cache . set_dirty() called, . but block already dirty . => it does nothing clear_dirty() . - block marked clean . - policy clear_dirty() called . Result: Block is marked clean even though it is actually dirty. No writeback will occur. Scenario B: Thread 1 Thread 2 cell_defer() . - cell removed from prison . - detained bios queued . clear_dirty() . - block marked clean . . incoming write bio . remapped to cache . set_dirty() called . - block marked dirty . - policy set_dirty() called - policy clear_dirty() called . Result: Block is properly marked as dirty, but policy thinks it is clean and therefore never asks us to writeback it. This case is visible in "dmsetup status" dirty block count (which normally decreases to 0 on a quiet device). Fix these issues by calling clear_dirty() before calling cell_defer(). Incoming bios for that block will then be detained in the cell and released only after clear_dirty() has completed, so the race will not occur. Found by inspecting the code after noticing spurious dirty counts (scenario B).

2014-09-10blk-mq: scale depth and rq map appropriate if low on memoryJens Axboe
If we are running in a kdump environment, resources are scarce. For some SCSI setups with a huge set of shared tags, we run out of memory allocating what the drivers is asking for. So implement a scale back logic to reduce the tag depth for those cases, allowing the driver to successfully load. We should extend this to detect low memory situations, and implement a sane fallback for those (1 queue, 64 tags, or something like that).

2014-09-10x86/xen: don't copy bogus duplicate entries into kernel page tablesStefan Bader
When RANDOMIZE_BASE (KASLR) is enabled; or the sum of all loaded modules exceeds 512 MiB, then loading modules fails with a warning (and hence a vmalloc allocation failure) because the PTEs for the newly-allocated vmalloc address space are not zero. WARNING: CPU: 0 PID: 494 at linux/mm/vmalloc.c:128 vmap_page_range_noflush+0x2a1/0x360() This is caused by xen_setup_kernel_pagetables() copying level2_kernel_pgt into level2_fixmap_pgt, overwriting many non-present entries. Without KASLR, the normal kernel image size only covers the first half of level2_kernel_pgt and module space starts after that. L4[511]->level3_kernel_pgt[510]->level2_kernel_pgt[ 0..255]->kernel [256..511]->module [511]->level2_fixmap_pgt[ 0..505]->module This allows 512 MiB of of module vmalloc space to be used before having to use the corrupted level2_fixmap_pgt entries. With KASLR enabled, the kernel image uses the full PUD range of 1G and module space starts in the level2_fixmap_pgt. So basically: L4[511]->level3_kernel_pgt[510]->level2_kernel_pgt[0..511]->kernel [511]->level2_fixmap_pgt[0..505]->module And now no module vmalloc space can be used without using the corrupt level2_fixmap_pgt entries. Fix this by properly converting the level2_fixmap_pgt entries to MFNs, and setting level1_fixmap_pgt as read-only. A number of comments were also using the the wrong L3 offset for level2_kernel_pgt. These have been corrected.

ForcePads are found on HP EliteBook 1040 laptops. They lack any kind of physical buttons, instead they generate primary button click when user presses somewhat hard on the surface of the touchpad. Unfortunately they also report primary button click whenever there are 2 or more contacts on the pad, messing up all multi-finger gestures (2-finger scrolling, multi-finger tapping, etc). To cope with this behavior we introduce a delay (currently 50 msecs) in reporting primary press in case more contacts appear.

2014-09-09Revert "ACPI / battery: fix wrong value of capacity_now reported when fully ↵Bjørn Mork
charged" This reverts commit 232de5143790 ("ACPI / battery: fix wrong value of capacity_now reported when fully charged") There is nothing wrong or unexpected about 'capacity_now' increasing above the last 'full_charge_capacity' value. Different charging cycles will cause 'full_charge_capacity' to vary, both up and down. Good battery firmwares will update 'full_charge_capacity' when the current charging cycle is complete, increasing it if necessary. It might even go above 'design_capacity' on a fresh and healthy battery. Capping 'capacity_now' to 'full_charge_capacity' is plain wrong, and printing a warning if this doesn't happen to match the 'design_capacity' is both annoying and terribly wrong. This results in bogus warnings on perfectly working systems/firmwares: [Firmware Bug]: battery: reported current charge level (39800) is higher than reported maximum charge level (39800). and wrong values being reported for 'capacity_now' and 'full_charge_capacity' after the warning has been triggered.

2014-09-09Revert "ACPI / battery: Fix warning message in acpi_battery_get_state()"Bjørn Mork
This reverts commit d719870b41e0 ("ACPI / battery: Fix warning message in acpi_battery_get_state()") Capping 'capacity_now' to 'full_charge_capacity' is plain wrong. If this is necessary to work around some buggy firmware, then the workaround needs protection against being applied to working firmwares. Good battery firmwares will allow 'capacity_now' to increase above 'full_charge_capacity', and will update the latter when the battery is fully charged. By capping 'capacity_now' we lose accurate capacity reporting until charging is complete whenever 'full_charge_capacity' needs to be increased.

2014-09-09arch/microblaze/include/asm/uaccess.h: Use pr_devel() instead of pr_debug()Chen Gang
When DYNAMIC_DEBUG enabled, pr_debug() depends on KBUILD_MODNAME which also depends on the modules number in Makefile. The related information in "scripts/Makefile.lib" line 94: # $(modname_flags) #defines KBUILD_MODNAME as the name of the module it will # end up in (or would, if it gets compiled in) # Note: Files that end up in two or more modules are compiled without the # KBUILD_MODNAME definition. The reason is that any made-up name would # differ in different configs. For this case, 'radio-si470x-i2c.o' and 'radio-si470x-common.o' are in one line, so cause compiling issue. And 'uaccess.h' is a common shared header (not specially for drivers), so use pr_devel() instead of is OK. The related error with allmodconfig: CC [M] drivers/media/radio/si470x/radio-si470x-i2c.o CC [M] drivers/media/radio/si470x/radio-si470x-common.o In file included from include/linux/printk.h:257:0, from include/linux/kernel.h:13, from drivers/media/radio/si470x/radio-si470x.h:29, from drivers/media/radio/si470x/radio-si470x-common.c:115: ./arch/microblaze/include/asm/uaccess.h: In function 'access_ok': include/linux/dynamic_debug.h:66:14: error: 'KBUILD_MODNAME' undeclared (first use in this function) .modname = KBUILD_MODNAME, \ ^ include/linux/dynamic_debug.h:76:2: note: in expansion of macro 'DEFINE_DYNAMIC_DEBUG_METADATA' DEFINE_DYNAMIC_DEBUG_METADATA(descriptor, fmt); \ ^ include/linux/printk.h:263:2: note: in expansion of macro 'dynamic_pr_debug' dynamic_pr_debug(fmt, ##__VA_ARGS__) ^ ./arch/microblaze/include/asm/uaccess.h:101:3: note: in expansion of macro 'pr_debug' pr_debug("ACCESS fail: %s at 0x%08x (size 0x%x), seg 0x%08x\n", ^ Signed-off-by: Chen Gang <gang.chen.5i5j@gmail.com> Signed-off-by: Michal Simek <michal.simek@xilinx.com>
