2010-11-25fuse: fix attributes after open(O_TRUNC)Ken Sumrall1-0/+10
The attribute cache for a file was not being cleared when a file is opened with O_TRUNC. If the filesystem's open operation truncates the file ("atomic_o_trunc" feature flag is set) then the kernel should invalidate the cached st_mtime and st_ctime attributes. Also i_size should be explicitly be set to zero as it is used sometimes without refreshing the cache. Signed-off-by: Ken Sumrall <[email protected]> Cc: Anfei <[email protected]> Cc: "Anand V.

2010-11-25sgi-xpc: XPC fails to discover partitions with all nasids above 128[email protected]1-10/+15
UV hardware defines 256 memory protection regions versus the baseline 64 with increasing size for the SN2 ia64. This was overlooked when XPC was modified to accomodate both UV and SN2. Without this patch, a user could reconfigure their existing system and suddenly disable cross-partition communications with no indication of what has gone wrong. It also prevents larger configurations from using cross-partition communication.

The find_next_bit, find_first_bit, find_next_zero_bit and find_first_zero_bit functions were not properly clamping to the maxbit argument at the bit level. They were instead only checking maxbit at the byte level. To fix this, add a compare and a conditional move instruction to the end of the common bit-within-the- byte code used by all the functions and be sure not to clobber the maxbit argument before it is used.

2010-11-24arch/tile: fix memchr() not to dereference memory for zero lengthChris Metcalf1-16/+19
This change fixes a bug that memchr() will read the first word of the source even if the length is zero. Ironically, the code was originally written with a test to avoid exactly this problem, but to make the code conform to Linux coding standards with all declarations preceding all statements, the first load from memory was moved up above that test as the initial value for a variable. The change just moves all the variable declarations to the top of the file, with no initializers, so that the test can also be at the top of the file. Signed-off-by: Chris Metcalf <[email protected]>

2010-11-24pci root complex: support for tile architectureChris Metcalf8-187/+705
This change enables PCI root complex support for TILEPro. Unlike TILE-Gx, TILEPro has no support for memory-mapped I/O, so the PCI support consists of hypervisor upcalls for PIO, DMA, etc. However, the performance is fine for the devices we have tested with so far (1Gb Ethernet, SATA, etc.). The <asm/io.h> header was tweaked to be a little bit more aggressive about disabling attempts to map/unmap IO port space. The hacky <asm/pci-bridge.h> header was rolled into the <asm/pci.h> header and the result was simplified. Both of the latter two headers were preliminary versions not meant for release before now - oh well. There is one quirk for our TILEmpower platform, which accidentally negotiates up to 5GT and needs to be kicked down to 2.5GT. Signed-off-by: Chris Metcalf <[email protected]>
2010-11-24drivers/net/tile/: on-chip network drivers for the tile architectureChris Metcalf12-2/+6510
This change adds the first network driver for the tile architecture, supporting the on-chip XGBE and GBE shims. The infrastructure is present for the TILE-Gx networking drivers (another three source files in the new directory) but for now the the actual tilegx sources are waiting on releasing hardware to initial customers. Note that arch/tile/include/hv/* are "upstream" headers from the Tilera hypervisor and will probably benefit less from LKML review. Signed-off-by: Chris Metcalf <[email protected]>

2010-11-24xen: x86/32: perform initial startup on initial_page_tableIan Campbell2-15/+56
Only make swapper_pg_dir readonly and pinned when generic x86 architecture code (which also starts on initial_page_table) switches to it. This helps ensure that the generic setup paths work on Xen unmodified. In particular clone_pgd_range writes directly to the destination pgd entries and is used to initialise swapper_pg_dir so we need to ensure that it remains writeable until the last possible moment during bring up. This is complicated slightly by the need to avoid sharing kernel PMD entries when running under Xen, therefore the Xen implementation must make a copy of the kernel PMD (which is otherwise referred to by both intial_page_table and swapper_pg_dir) before switching to swapper_pg_dir.

2010-11-24md: Call blk_queue_flush() to establish flush/fua supportDarrick J. Wong1-0/+2
Before 2.6.37, the md layer had a mechanism for catching I/Os with the barrier flag set, and translating the barrier into barriers for all the underlying devices. With 2.6.37, I/O barriers have become plain old flushes, and the md code was updated to reflect this. However, one piece was left out -- the md layer does not tell the block layer that it supports flushes or FUA access at all, which results in md silently dropping flush requests. Since the support already seems there, just add this one piece of bookkeeping. Signed-off-by: Darrick J. Wong <[email protected]> Signed-off-by: NeilBrown <[email protected]>
2010-11-24md/raid1: really fix recovery looping when single good device fails.NeilBrown1-0/+1
Commit 4044ba58dd15cb01797c4fd034f39ef4a75f7cc3 supposedly fixed a problem where if a raid1 with just one good device gets a read-error during recovery, the recovery would abort and immediately restart in an infinite loop. However it depended on raid1_remove_disk removing the spare device from the array. But that does not happen in this case. So add a test so that in the 'recovery_disabled' case, the device will be removed. This suitable for any kernel since 2.6.29 which is when recovery_disabled was introduced.

2010-11-24md: fix return value of rdev_size_change()Justin Maggard1-2/+2
When trying to grow an array by enlarging component devices, rdev_size_store() expects the return value of rdev_size_change() to be in sectors, but the actual value is returned in KBs. This functionality was broken by commit dd8ac336c13fd8afdb082ebacb1cddd5cf727889 so this patch is suitable for any kernel since 2.6.30.

2010-11-24virtio: fix format of sysfs driver/vendor filesStephen Hemminger1-3/+3
The sysfs files for virtio produce the wrong format and are missing the required newline. The output for virtio bus vendor/device should have the same format as the corresponding entries for PCI devices. Although this technically changes the ABI for sysfs, these files were broken to start with! Signed-off-by: Stephen Hemminger <[email protected]> Signed-off-by: Rusty Russell <[email protected]>
2010-11-24Char: virtio_console, fix memory leakJiri Slaby1-28/+9
Stanse found that in init_vqs, memory is leaked under certain circumstanses (the fail path order is incorrect). Fix that by checking allocations in one turn and free all of them at once if some fails (some may be NULL, but this is OK).

2010-11-24virtio: return correct capacity to usersMichael S. Tsirkin1-3/+0
We can't rely on indirect buffers for capacity calculations because they need a memory allocation which might fail. In particular, virtio_net can get into this situation under stress, and it drops packets and performs badly. So return the number of buffers we can guarantee users. Signed-off-by: Michael S.
