fe85227 | Ming Lei | 22 June 2012, 10:49:35 UTC | Revert "mmc: omap_hsmmc: Enable Auto CMD12" This patch reverts the commit dba3c29ea4a1d5d544. After bisecting, this commit dba3c29 is found to ruin micro-SD card data (writing incorrect file, or fs is corrupt after several times mount) on the beagle-xm revB, and reverting the commit will fix the problem. Also from TRM of OMAP3/OMAP4/DM37x, the below is mentioned about the Auto CMD12 Enable bit. - SDIO does not support this feature. - SD card only. Looks it is not suitable to always enable Auto CMD12 in host controller driver. Considered that the commit is not mature enough, so ask to revert it first.

d380443 | Subhash Jadavani | 13 June 2012, 11:40:43 UTC | mmc: block: fix the data timeout issue with ACMD22 If multi block write operation fails for SD card, during error handling we send the SD_APP_SEND_NUM_WR_BLKS (ACMD22) to know how many blocks were already programmed by card. But mmc_sd_num_wr_blocks() function which sends the ACMD22 calculates the data timeout value from csd.tacc_ns and csd.tacc_clks parameters which will be 0 for block addressed (>2GB cards) SD card. This would result in timeout_ns and timeout_clks being 0 in the mmc_request passed to host driver. This means host controller would program its data timeout timer value with 0 which could result in DATA TIMEOUT errors from controller. To fix this issue, mmc_sd_num_wr_blocks() should instead just call the mmc_set_data_timeout() to calculate the data timeout value. mmc_set_data_timeout() function ensures that non zero timeout value is set even for block addressed SD cards.

The code checks for >= NV_10 for 2 CRTCs, then downgrades a few specific chipsets to 1 CRTC based on (pci_device & 0x0ff0). The breakage example seen is on GTX 560Ti, with a pciid of 0x1200, which gets detected as an NV20 (0x020x) with 1 CRTC by nv_two_heads(), causing memory corruption because there's actually 2 CRTCs.. This switches fbcon to use the CRTC count directly from the mode_config structure, which will also fix the same issue on Kepler boards which have 4 CRTCs.

Commit 2603efa31a03 ("bug.h: Fix up powerpc build regression") corrected the powerpc build case and extended the __ASSEMBLY__ guards, but it also got caught in pre-processor hell accidentally matching the else case of CONFIG_BUG resulting in the BUG disabled case tripping up on -Werror=implicit-function-declaration. It's not possible to __ASSEMBLY__ guard the entire file as architecture code needs to get at the BUGFLAG_WARNING definition in the GENERIC_BUG case, but the rest of the CONFIG_BUG=y/n case needs to be guarded. Rather than littering endless __ASSEMBLY__ checks in each of the if/else cases we just move the BUGFLAG definitions up under their own GENERIC_BUG test and then shove everything else under one big __ASSEMBLY__ guard. Build tested on all of x86 CONFIG_BUG=y, CONFIG_BUG=n, powerpc (due to it's dependence on BUGFLAG definitions in assembly code), and sh (due to not bringing in linux/kernel.h to satisfy the taint flag definitions used by the generic bug code). Hopefully that's the end of the corner cases and I can abstain from ever having to touch this infernal header ever again.

593f473 | Marek Szyprowski | 21 June 2012, 09:48:11 UTC | ARM: dma-mapping: fix buffer chunk allocation order IOMMU-aware dma_alloc_attrs() implementation allocates buffers in power-of-two chunks to improve performance and take advantage of large page mappings provided by some IOMMU hardware. However current code, due to a subtle bug, allocated those chunks in the smallest-to-largest order, what completely killed all the advantages of using larger than page chunks. If a 4KiB chunk has been mapped as a first chunk, the consecutive chunks are not aligned correctly to the power-of-two which match their size and IOMMU drivers were not able to use internal mappings of size other than the 4KiB (largest common denominator of alignment and chunk size). This patch fixes this issue by changing to the correct largest-to-smallest chunk size allocation sequence. Signed-off-by: Marek Szyprowski <m.szyprowski@samsung.com> | 25 June 2012, 08:18:52 UTC |

59c84ed | Jan Kara | 05 June 2012, 22:32:26 UTC | xfs: Fix overallocation in xfs_buf_allocate_memory() Commit de1cbee which removed b_file_offset in favor of b_bn introduced a bug causing xfs_buf_allocate_memory() to overestimate the number of necessary pages. The problem is that xfs_buf_alloc() sets b_bn to -1 and thus effectively every buffer is straddling a page boundary which causes xfs_buf_allocate_memory() to allocate two pages and use vmalloc() for access which is unnecessary. Dave says xfs_buf_alloc() doesn't need to set b_bn to -1 anymore since the buffer is inserted into the cache only after being fully initialized now. So just make xfs_buf_alloc() fill in proper block number from the beginning.

The inode item is then marked as flushing, which causes xfsaild to spin and leaves the filesystem stalled. This is reproduced by running xfstests 273 in a loop for an extended period of time. Check for stale inodes before the flush lock. This marks the inode as pinned, leads to a log flush and allows the filesystem to proceed.

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.

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.

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.

66f9311 | Alain Renaud | 08 June 2012, 19:34:46 UTC | xfs: xfs_vm_writepage clear iomap_valid when !buffer_uptodate (REV2) On filesytems with a block size smaller than PAGE_SIZE we currently have a problem with unwritten extents. If a we have multi-block page for which an unwritten extent has been allocated, and only some of the buffers have been written to, and they are not contiguous, we can expose stale data from disk in the blocks between the writes after extent conversion. Example of a page with unwritten and real data. buffer content 0 empty b_state = 0 1 DATA b_state = 0x1023 Uptodate,Dirty,Mapped,Unwritten 2 DATA b_state = 0x1023 Uptodate,Dirty,Mapped,Unwritten 3 empty b_state = 0 4 empty b_state = 0 5 DATA b_state = 0x1023 Uptodate,Dirty,Mapped,Unwritten 6 DATA b_state = 0x1023 Uptodate,Dirty,Mapped,Unwritten 7 empty b_state = 0 Buffers 1, 2, 5, and 6 have been written to, leaving 0, 3, 4, and 7 empty. Currently buffers 1, 2, 5, and 6 are added to a single ioend, and when IO has completed, extent conversion creates a real extent from block 1 through block 6, leaving 0 and 7 unwritten. However buffers 3 and 4 were not written to disk, so stale data is exposed from those blocks on a subsequent read. Fix this by setting iomap_valid = 0 when we find a buffer that is not Uptodate. This ensures that buffers 5 and 6 are not added to the same ioend as buffers 1 and 2. Later these blocks will be converted into two separate real extents, leaving the blocks in between unwritten.

aef2b89 | Russ Dill | 09 May 2012, 22:15:03 UTC | ARM: OMAP: Fix Beagleboard DVI reset gpio Commit e813a55eb9c9bc6c8039fb16332cf43402125b30 ("OMAP: board-files: remove custom PD GPIO handling for DVI output") moved TFP410 chip's powerdown-gpio handling from the board files to the tfp410 driver. One gpio_request_one(powerdown-gpio, ...) was mistakenly left unremoved in the Beagle board file. This causes the tfp410 driver to fail to request the gpio on Beagle, causing the driver to fail and thus the DVI output doesn't work. This patch removes several boot errors from board-omap3beagle.c: - gpio_request: gpio--22 (DVI reset) status -22 - Unable to get DVI reset GPIO There is a combination of leftover code and revision confusion. Additionally, xM support is currently a hack. For original Beagleboard this removes the double initialization of GPIO 170, properly configures it as an output, and wraps the initialization in an if block so that xM does not attempt to request it. For Beagleboard xM it removes reference to GPIO 129 which was part of rev A1 and A2 designs, but never functioned. It then properly assigns beagle_dvi_device.reset_gpio in beagle_twl_gpio_setup and removes the hack of initializing it high. Additionally, it uses gpio_set_value_cansleep since this GPIO is connected through i2c. Unfortunately, there is no way to tell the difference between xM A2 and A3. However, GPIO 129 does not function on rev A1 and A2, and the TWL GPIO used on A3 and beyond is not used on rev A1 and A2, there are no problems created by this fix. Tested on Beagleboard-xM Rev C1 and Beagleboard Rev B4.

310018d | Tony Lindgren | 20 June 2012, 14:18:15 UTC | ARM: OMAP2+: Fix MUSB ifdefs for platform init code Commit 62285963 (usb: musb: drop a gigantic amount of ifdeferry) got rid of a bunch of ifdefs in the MUSB code. Looks like the platform init code is still using these dropped defines though, which in many cases results the board defaulting always to host mode. Currently the situation is that USB_MUSB_HDRC is the main Kconfig option with additional USB_GADGET_MUSB_HDRC so only these two should be used to select between host and OTG mode. Fix the situation for omaps. The following users should fix the platform init code in a similar way: Dropped Kconfig option Current users USB_MUSB_OTG blackfin, davinci, not in Kconfigs USB_MUSB_PERIPHERAL davinci, not in Kconfigs USB_MUSB_HOST davinci, not in Kconfigs USB_MUSB_HDRC_HCD blackfin, not in Kconfigs USB_MUSB_OTG blackfin, not in Kconfigs Cc: Mike Frysinger <vapier@gentoo.org> Cc: Sekhar Nori <nsekhar@ti.com> Cc: linux-usb@vger.kernel.org Cc: Felipe Balbi <balbi@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com> | 20 June 2012, 14:18:15 UTC |
642c0db | Sage Weil | 11 June 2012, 03:43:56 UTC | libceph: flush msgr queue during mon_client shutdown We need to flush the msgr workqueue during mon_client shutdown to ensure that any work affecting our embedded ceph_connection is finished so that we can be safely destroyed. Previously, we were flushing the work queue after osd_client shutdown and before mon_client shutdown to ensure that any osd connection refs to authorizers are flushed. Remove the redundant flush, and document in the comment that the mon_client flush is needed to cover that case as well.

88ed6ea | Sage Weil | 01 June 2012, 03:22:18 UTC | libceph: use con get/put ops from osd_client There were a few direct calls to ceph_con_{get,put}() instead of the con ops from osd_client.c. This is a bug since those ops aren't defined to be ceph_con_get/put. This breaks refcounting on the ceph_osd structs that contain the ceph_connections, and could lead to all manner of strangeness. The purpose of the ->get and ->put methods in a ceph connection are to allow the connection to indicate it has a reference to something external to the messaging system, *not* to indicate something external has a reference to the connection.
