2011-09-14xfs: fix a use after free in xfs_end_io_direct_writeChristoph Hellwig1-1/+2
There is a window in which the ioend that we call inode_dio_wake on in xfs_end_io_direct_write is already free. Fix this by storing the inode pointer in a local variable. This is a fix for the regression introduced in 3.1-rc by "fs: move inode_dio_done to the end_io handler".

In pcie_find_smpss(), we have the following statement: if (dev->is_hotplug_bridge && (!list_is_singular(&dev->bus->devices) || dev->bus->self->pcie_type != PCI_EXP_TYPE_ROOT_PORT)) The problem is that at least on my machine, this gets called for the root complex (virtual P2P bridge), and dev->bus->self is NULL since the parent bus for this is not itself anchor to a PCI device.

2011-09-13nfs: Do not allow multiple mounts on same mountpoint when using -o noacSachin Prabhu1-3/+20
Do not allow multiple mounts on same mountpoint when using -o noac When you normally attempt to mount a share twice on the same mountpoint, a check in do_add_mount causes it to return an error # mount localhost:/nfsv3 /mnt # mount localhost:/nfsv3 /mnt mount.nfs: /mnt is already mounted or busy However when using the option 'noac', the user is able to mount the same share on the same mountpoint multiple times. This happens because a share mounted with the noac option is automatically assigned the 'sync' flag MS_SYNCHRONOUS in nfs_initialise_sb(). This flag is set after the check for already existing superblocks is done in sget(). The check for the mount flags in nfs_compare_mount_options() does not take into account the 'sync' flag applied later on in the code path. This means that when using 'noac', a new superblock structure is assigned for every new mount of the same share and multiple shares on the same mountpoint are allowed. ie. # mount -onoac localhost:/nfsv3 /mnt can be run multiple times. The patch checks for noac and assigns the sync flag before sget() is called to obtain an already existing superblock structure.

2011-09-13xen/e820: if there is no dom0_mem=, don't tweak extra_pages.David Vrabel1-4/+6
The patch "xen: use maximum reservation to limit amount of usable RAM" (d312ae878b6aed3912e1acaaf5d0b2a9d08a4f11) breaks machines that do not use 'dom0_mem=' argument with: reserve RAM buffer: 000000133f2e2000 - 000000133fffffff (XEN) mm.c:4976:d0 Global bit is set to kernel page fffff8117e (XEN) domain_crash_sync called from entry.S (XEN) Domain 0 (vcpu#0) crashed on cpu#0: ... The reason being that the last E820 entry is created using the 'extra_pages' (which is based on how many pages have been freed). The mentioned git commit sets the initial value of 'extra_pages' using a hypercall which returns the number of pages (if dom0_mem has been used) or -1 otherwise. If the later we return with MAX_DOMAIN_PAGES as basis for calculation: return min(max_pages, MAX_DOMAIN_PAGES); and use it: extra_limit = xen_get_max_pages(); if (extra_limit >= max_pfn) extra_pages = extra_limit - max_pfn; else extra_pages = 0; which means we end up with extra_pages = 128GB in PFNs (33554432) - 8GB in PFNs (2097152, on this specific box, can be larger or smaller), and then we add that value to the E820 making it: Xen: 00000000ff000000 - 0000000100000000 (reserved) Xen: 0000000100000000 - 000000133f2e2000 (usable) which is clearly wrong. It should look as so: Xen: 00000000ff000000 - 0000000100000000 (reserved) Xen: 0000000100000000 - 000000027fbda000 (usable) Naturally this problem does not present itself if dom0_mem=max:X is used.

2011-09-13hwmon: (pmbus) Fix low limit temperature alarmsGuenter Roeck1-1/+8
Temperature alarms are detected by checking the alarm bit and comparing temperature limits against the current temperature. For low limits, this comparison needs to be reversed (temp < limit instead of temp > limit). This was not taken into account, resulting in wrong alarms if a temperature fell below a low limit. Fix by adding a low limit flag in the limit data structure. When creating the sensor entry, the order of registers to compare is now reversed for low limits.

This results in jumpy 1 finger touch and totally invalid 2nd finger data. For touch detection, switch to a Touch Present single bit that all versions of Bamboo support. For touch 2 offset, calculate offset based on a bit that is set different between the two packet layouts.

2011-09-12genirq: Make irq_shutdown() symmetric vs. irq_startup againGeert Uytterhoeven1-1/+1
If an irq_chip provides .irq_shutdown(), but neither of .irq_disable() or .irq_mask(), free_irq() crashes when jumping to NULL. Fix this by only trying .irq_disable() and .irq_mask() if there's no .irq_shutdown() provided. This revives the symmetry with irq_startup(), which tries .irq_startup(), .irq_enable(), and irq_unmask(), and makes it consistent with the comment for irq_chip.irq_shutdown() in <linux/irq.h>, which says: * @irq_shutdown: shut down the interrupt (defaults to ->disable if NULL) This is also how __free_irq() behaved before the big overhaul, cfr. e.g. 3b56f0585fd4c02d047dc406668cb40159b2d340 ("genirq: Remove bogus conditional"), where the core interrupt code always overrode .irq_shutdown() to .irq_disable() if .irq_shutdown() was NULL.

2011-09-11Btrfs: fix wrong nbytes information of the inodeMiao Xie1-2/+2
If we write some data into the data hole of the file(no preallocation for this hole), Btrfs will allocate some disk space, and update nbytes of the inode, but the other element--disk_i_size needn't be updated. At this condition, we must update inode metadata though disk_i_size is not changed(btrfs_ordered_update_i_size() return 1). # mkfs.btrfs /dev/sdb1 # mount /dev/sdb1 /mnt # touch /mnt/a # truncate -s 856002 /mnt/a # dd if=/dev/zero of=/mnt/a bs=4K count=1 conv=nocreat,notrunc # umount /mnt # btrfsck /dev/sdb1 root 5 inode 257 errors 400 found 32768 bytes used err is 1 Signed-off-by: Miao Xie <[email protected]> Signed-off-by: Chris Mason <[email protected]>
2011-09-11Btrfs: fix the file extent gap when doing direct IOMiao Xie1-6/+10
When we write some data to the place that is beyond the end of the file in direct I/O mode, a data hole will be created. And Btrfs should insert a file extent item that point to this hole into the fs tree. But unfortunately Btrfs forgets doing it. The following is a simple way to reproduce it: # mkfs.btrfs /dev/sdc2 # mount /dev/sdc2 /test4 # touch /test4/a # dd if=/dev/zero of=/test4/a seek=8 count=1 bs=4K oflag=direct conv=nocreat,notrunc # umount /test4 # btrfsck /dev/sdc2 root 5 inode 257 errors 100 Reported-by: Tsutomu Itoh <[email protected]> Signed-off-by: Miao Xie <[email protected]> Tested-by: Tsutomu Itoh <[email protected]> Signed-off-by: Chris Mason <[email protected]>

2011-09-11Btrfs: fix misuse of trans block rsvLiu Bo1-0/+4

2011-09-11Btrfs: reset to appropriate block rsv after orphan operationsLiu Bo1-0/+4
While truncating free space cache, we forget to change trans->block_rsv back to the original one, but leave it with the orphan_block_rsv, and then with option inode_cache enable, it leads to countless warnings of btrfs_alloc_free_block and btrfs_orphan_commit_root: WARNING: at fs/btrfs/extent-tree.c:5711 btrfs_alloc_free_block+0x180/0x350 [btrfs]() ...

2011-09-11Btrfs: skip locking if searching the commit root in csum lookupJosef Bacik1-1/+3
It's not enough to just search the commit root, since we could be cow'ing the very block we need to search through, which would mean that its locked and we'll still deadlock.
