2016-04-07arc: Add our own implementation of fb_pgprotect()Alexey Brodkin1-0/+19
During mmaping of frame-buffer pages to user-space fb_protect() is called to set proper page settings. In case of ARC we need to mark pages that are mmaped to user as uncached because of 2 reasons: * Huge amount of data if passing through data cache will thrash cache a lot making cache almost useless for other less traffic hungry processes. * Data written by user in FB will be immediately available for hardware (such as PGU etc) without requirements to flush data cache regularly.

2016-04-07ARC: Don't source drivers/pci/pcie/Kconfig ourselvesAndreas Ziegler1-1/+0
Commit 5f8fc43217a0 ("PCI: Include pci/pcie/Kconfig directly from pci/Kconfig") in linux-next changed drivers/pci/Kconfig to include drivers/pci/pcie/Kconfig itself, so that architectures do not need to source both files themselves. ARC just recently gained PCI support through commit 6b3fb77998dd ("ARC: Add PCI support"), but this change was based on the old behaviour of the Kconfig files. This makes Kconfig now spit out the following warnings: drivers/pci/pcie/Kconfig:61:warning: choice value used outside its choice group drivers/pci/pcie/Kconfig:67:warning: choice value used outside its choice group drivers/pci/pcie/Kconfig:74:warning: choice value used outside its choice group This change updates the Kconfig file for ARC, dropping the now unnecessary 'source' statement, which makes the warning disappear.

A Fedora user reports that the ftdi_sio driver works properly for the ICP DAS I-7561U device. Further, the user manual for these devices instructs users to load the driver and add the ids using the sysfs interface.

2016-04-06Btrfs: fix file/data loss caused by fsync after rename and new inodeFilipe Manana1-0/+137
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.

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).

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.

2016-04-06i40iw: avoid potential uninitialized variable useArnd Bergmann1-7/+3
gcc finds that the i40iw_make_cm_node() function in the recently added i40iw driver uses an uninitilized variable as an index into an array if CONFIG_IPV6 is disabled and the driver uses IPv6 mode: drivers/infiniband/hw/i40iw/i40iw_cm.c: In function 'i40iw_make_cm_node': drivers/infiniband/hw/i40iw/i40iw_cm.c:2206:52: error: 'arpindex' may be used uninitialized in this function [-Werror=maybe-uninitialized] ether_addr_copy(cm_node->rem_mac, iwdev->arp_table[arpindex].mac_addr); As far as I can tell, this code path can not be used because the ipv4 variable is always set with CONFIG_IPV6 is disabled, but it's better to be sure and prevent the undefined behavior, as well as shut up that warning in a proper way. This adds an 'else' clause for the case we get the warning about, causing the function to return an error in a controlled way. To avoid adding extra mess with combined io()/#ifdef clauses, I'm also converting the existing #ifdef into a more readable if(IS_ENABLED()) check.

2016-04-05e1000: Double Tx descriptors needed check for 82544Alexander Duyck1-1/+18
The 82544 has code that adds one additional descriptor per data buffer. However we weren't taking that into account when determining the descriptors needed for the next transmit at the end of the xmit_frame path. This change takes that into account by doubling the number of descriptors needed for the 82544 so that we can avoid a potential issue where we could hang the Tx ring by loading frames with xmit_more enabled and then stopping the ring without writing the tail. In addition it adds a few more descriptors to account for some additional workarounds that have been added over time.

2016-04-05e1000: Do not overestimate descriptor counts in Tx pre-checkAlexander Duyck1-1/+1
The current code path is capable of grossly overestimating the number of descriptors needed to transmit a new frame. This specifically occurs if the skb contains a number of 4K pages. The issue is that the logic for determining the descriptors needed is ((S) >> (X)) + 1. When X is 12 it means that we were indicating that we required 2 descriptors for each 4K page when we only needed one. This change corrects this by instead adding (1 << (X)) - 1 to the S value instead of adding 1 after the fact. This way we get an accurate descriptor needed count as we are essentially doing a DIV_ROUNDUP().

2016-04-05rbd: use GFP_NOIO consistently for request allocationsDavid Disseldorp1-3/+3
As of 5a60e87603c4c533492c515b7f62578189b03c9c, RBD object request allocations are made via rbd_obj_request_create() with GFP_NOIO. However, subsequent OSD request allocations in rbd_osd_req_create*() use GFP_ATOMIC. With heavy page cache usage (e.g. OSDs running on same host as krbd client), rbd_osd_req_create() order-1 GFP_ATOMIC allocations have been observed to fail, where direct reclaim would have allowed GFP_NOIO allocations to succeed.
