git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-linus Felipe writes: usb: fixes for v4.6-rc3 We have two more fixes to f_midi. It should now behave much better. dwc3-keystone.c has gotten a fix which now allows it to work on keystone device when running in peripheral mode. A similar fix for DMA configuration was made for udc-core, too. We have a new PCI ID for Intel's Broxton platform. DWC3 can run on those platforms as well. And we also have some dwc2 got a fix for dr_mode usage, while renesas controller got 3 important fixes: a NULL pointer deref fix, IRQ <-> DMA race fix, and a fix to prevent a situation where we would queue a request to a disabled endpoint.

2016-04-07iommu/rockchip: Fix "is stall active" checkJohn Keeping
Since commit cd6438c5f844 ("iommu/rockchip: Reconstruct to support multi slaves") rk_iommu_is_stall_active() always returns false because the bitwise AND operates on the boolean flag promoted to an integer and a value that is either zero or BIT(2). Explicitly convert the right-hand value to a boolean so that both sides are guaranteed to be either zero or one. rk_iommu_is_paging_enabled() does not suffer from the same problem since RK_MMU_STATUS_PAGING_ENABLED is BIT(0), but let's apply the same change for consistency and to make it clear that it's correct without needing to lookup the value.

IOMMU drivers that do not support default domains, but make use of the the group->domain pointer can get that pointer overwritten with NULL on device add/remove. Make sure this can't happen by only overwriting the domain pointer when it is NULL.

2016-04-07virtio: add VIRTIO_CONFIG_S_NEEDS_RESET device status bitStefan Hajnoczi
The VIRTIO 1.0 specification added the DEVICE_NEEDS_RESET device status bit in "VIRTIO-98: Add DEVICE_NEEDS_RESET". This patch defines the device status bit in the uapi header file so that both the kernel and userspace applications can use it. The bit is currently unused by the virtio guest drivers and vhost. According to the spec "a good implementation will try to recover by issuing a reset". This is not attempted here because it requires auditing the virtio drivers to ensure there are no resource leaks or crashes if the device needs to be reset mid-operation. See "2.1 Device Status Field" in the VIRTIO 1.0 specification for details. Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>

2016-04-06Btrfs: fix file/data loss caused by fsync after rename and new inodeFilipe Manana
If we rename an inode A (be it a file or a directory), create a new inode B with the old name of inode A and under the same parent directory, fsync inode B and then power fail, at log tree replay time we end up removing inode A completely. If inode A is a directory then all its files are gone too. Example scenarios where this happens: This is reproducible with the following steps, taken from a couple of test cases written for fstests which are going to be submitted upstream soon: # Scenario 1 mkfs.btrfs -f /dev/sdc mount /dev/sdc /mnt mkdir -p /mnt/a/x echo "hello" > /mnt/a/x/foo echo "world" > /mnt/a/x/bar sync mv /mnt/a/x /mnt/a/y mkdir /mnt/a/x xfs_io -c fsync /mnt/a/x <power failure happens> The next time the fs is mounted, log tree replay happens and the directory "y" does not exist nor do the files "foo" and "bar" exist anywhere (neither in "y" nor in "x", nor the root nor anywhere). # Scenario 2 mkfs.btrfs -f /dev/sdc mount /dev/sdc /mnt mkdir /mnt/a echo "hello" > /mnt/a/foo sync mv /mnt/a/foo /mnt/a/bar echo "world" > /mnt/a/foo xfs_io -c fsync /mnt/a/foo <power failure happens> The next time the fs is mounted, log tree replay happens and the file "bar" does not exists anymore. A file with the name "foo" exists and it matches the second file we created. Another related problem that does not involve file/data loss is when a new inode is created with the name of a deleted snapshot and we fsync it: mkfs.btrfs -f /dev/sdc mount /dev/sdc /mnt mkdir /mnt/testdir btrfs subvolume snapshot /mnt /mnt/testdir/snap btrfs subvolume delete /mnt/testdir/snap rmdir /mnt/testdir mkdir /mnt/testdir xfs_io -c fsync /mnt/testdir # or fsync some file inside /mnt/testdir <power failure> The next time the fs is mounted the log replay procedure fails because it attempts to delete the snapshot entry (which has dir item key type of BTRFS_ROOT_ITEM_KEY) as if it were a regular (non-root) entry, resulting in the following error that causes mount to fail: [52174.510532] BTRFS info (device dm-0): failed to delete reference to snap, inode 257 parent 257 [52174.512570] ------------[ cut here ]------------ [52174.513278] WARNING: CPU: 12 PID: 28024 at fs/btrfs/inode.c:3986 __btrfs_unlink_inode+0x178/0x351 [btrfs]() [52174.514681] BTRFS: Transaction aborted (error -2) [52174.515630] Modules linked in: btrfs dm_flakey dm_mod overlay crc32c_generic ppdev xor raid6_pq acpi_cpufreq parport_pc tpm_tis sg parport tpm evdev i2c_piix4 proc [52174.521568] CPU: 12 PID: 28024 Comm: mount Tainted: G W 4.5.0-rc6-btrfs-next-27+ #1 [52174.522805] Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS by qemu-project.org 04/01/2014 [52174.524053] 0000000000000000 ffff8801df2a7710 ffffffff81264e93 ffff8801df2a7758 [52174.524053] 0000000000000009 ffff8801df2a7748 ffffffff81051618 ffffffffa03591cd [52174.524053] 00000000fffffffe ffff88015e6e5000 ffff88016dbc3c88 ffff88016dbc3c88 [52174.524053] Call Trace: [52174.524053] [<ffffffff81264e93>] dump_stack+0x67/0x90 [52174.524053] [<ffffffff81051618>] warn_slowpath_common+0x99/0xb2 [52174.524053] [<ffffffffa03591cd>] ? __btrfs_unlink_inode+0x178/0x351 [btrfs] [52174.524053] [<ffffffff81051679>] warn_slowpath_fmt+0x48/0x50 [52174.524053] [<ffffffffa03591cd>] __btrfs_unlink_inode+0x178/0x351 [btrfs] [52174.524053] [<ffffffff8118f5e9>] ? iput+0xb0/0x284 [52174.524053] [<ffffffffa0359fe8>] btrfs_unlink_inode+0x1c/0x3d [btrfs] [52174.524053] [<ffffffffa038631e>] check_item_in_log+0x1fe/0x29b [btrfs] [52174.524053] [<ffffffffa0386522>] replay_dir_deletes+0x167/0x1cf [btrfs] [52174.524053] [<ffffffffa038739e>] fixup_inode_link_count+0x289/0x2aa [btrfs] [52174.524053] [<ffffffffa038748a>] fixup_inode_link_counts+0xcb/0x105 [btrfs] [52174.524053] [<ffffffffa038a5ec>] btrfs_recover_log_trees+0x258/0x32c [btrfs] [52174.524053] [<ffffffffa03885b2>] ? replay_one_extent+0x511/0x511 [btrfs] [52174.524053] [<ffffffffa034f288>] open_ctree+0x1dd4/0x21b9 [btrfs] [52174.524053] [<ffffffffa032b753>] btrfs_mount+0x97e/0xaed [btrfs] [52174.524053] [<ffffffff8108e1b7>] ? trace_hardirqs_on+0xd/0xf [52174.524053] [<ffffffff8117bafa>] mount_fs+0x67/0x131 [52174.524053] [<ffffffff81193003>] vfs_kern_mount+0x6c/0xde [52174.524053] [<ffffffffa032af81>] btrfs_mount+0x1ac/0xaed [btrfs] [52174.524053] [<ffffffff8108e1b7>] ? trace_hardirqs_on+0xd/0xf [52174.524053] [<ffffffff8108c262>] ? lockdep_init_map+0xb9/0x1b3 [52174.524053] [<ffffffff8117bafa>] mount_fs+0x67/0x131 [52174.524053] [<ffffffff81193003>] vfs_kern_mount+0x6c/0xde [52174.524053] [<ffffffff8119590f>] do_mount+0x8a6/0x9e8 [52174.524053] [<ffffffff811358dd>] ? strndup_user+0x3f/0x59 [52174.524053] [<ffffffff81195c65>] SyS_mount+0x77/0x9f [52174.524053] [<ffffffff814935d7>] entry_SYSCALL_64_fastpath+0x12/0x6b [52174.561288] ---[ end trace 6b53049efb1a3ea6 ]--- Fix this by forcing a transaction commit when such cases happen.

2016-04-06x86: remove the kernel code/data/bss resources from /proc/iomemLinus Torvalds
Let's see if anybody even notices. I doubt anybody uses this, and it does expose addresses that should be randomized, so let's just remove the code. It's old and traditional, and it used to be cute, but we should have removed this long ago. If it turns out anybody notices and this breaks something, we'll have to revert this, and maybe we'll end up using other approaches instead (using %pK or similar). But removing unnecessary code is always the preferred option. Noted-by: Emrah Demir <ed@abdsec.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2016-04-06VSOCK: Detach QP check should filter out non matching QPs.Jorgen Hansen
The check in vmci_transport_peer_detach_cb should only allow a detach when the qp handle of the transport matches the one in the detach message. Testing: Before this change, a detach from a peer on a different socket would cause an active stream socket to register a detach.

2016-04-06stmmac: fix adjust link call in case of a switch is attachedGiuseppe CAVALLARO
While initializing the phy, the stmmac driver sets the PHY_IGNORE_INTERRUPT so the PAL won't call the adjust hook that is needed, on some platforms, e.g. STi, to invoke the glue. The patch allows the PAL to poll the stmmac_adjust_link just one time in case of a switch is attached, setting later the PHY_IGNORE_INTERRUPT flag. Moving this kind of logic inside the adjust_link it makes sense to anticipate the check for EEE that will never initialized in this scenario.
