  • 937c30d7f   crypto: serpent - add 8-way parallel x86_64/SSE2 assembler implementation ... Browse Code »

    Patch adds x86_64/SSE2 assembler implementation of serpent cipher. Assembler
    functions crypt data in eigth block chunks (two 4 block chunk SSE2 operations
    in parallel to improve performance on out-of-order CPUs). Glue code is based
    on one from AES-NI implementation, so requests from irq context are redirected
    to cryptd.

    v2:
    - add missing include of linux/module.h
    (appearently crypto.h used to include module.h, which changed for 3.2 by
    commit 7c926402a7e8c9b279968fd94efec8700ba3859e)

  • a3fbbde70   VFS: we need to set LOOKUP_JUMPED on mountpoint crossing ... Browse Code »
    1

    Mountpoint crossing is similar to following procfs symlinks - we do
    not get ->d_revalidate() called for dentry we have arrived at, with
    unpleasant consequences for NFS4.

    Simple way to reproduce the problem in mainline:

    cat >/tmp/a.c <
    #include
    #include
    main()
    {
    struct flock fl = {.l_type = F_RDLCK, .l_whence = SEEK_SET, .l_len = 1};
    if (fcntl(0, F_SETLK, &fl))
    perror("setlk");
    }
    EOF
    cc /tmp/a.c -o /tmp/test

    then on nfs4:

    mount --bind file1 file2
    /tmp/test < file1 # ok
    /tmp/test < file2 # spews "setlk: No locks available"...

    What happens is the missing call of ->d_revalidate() after mountpoint
    crossing and that's where NFS4 would issue OPEN request to server.

    The fix is simple - treat mountpoint crossing the same way we deal with
    following procfs-style symlinks. I.e. set LOOKUP_JUMPED...

  • 0bdfea8ba   forcedeth: Improve stats counters ... Browse Code »

    Rx byte count was off; instead use the hardware's count. Tx packet
    count was counting pre-TSO packets; instead count on-the-wire packets.
    Report hardware dropped frame count as rx_fifo_errors.

    - The count of transmitted packets reported by the forcedeth driver
    reports pre-TSO (TCP Segmentation Offload) packet counts and not the
    count of the number of packets sent on the wire. This change fixes
    the forcedeth driver to report the correct count. Fixed the code by
    copying the count stored in the NIC H/W to the value reported by the
    driver.

    - Count rx_drop_frame errors as rx_fifo_errors:
    We see a lot of rx_drop_frame errors if we disable the rx bottom-halves
    for too long. Normally, rx_fifo_errors would be counted in this case.
    The rx_drop_frame error count is private to forcedeth and is not
    reported by ifconfig or sysfs. The rx_fifo_errors count is currently
    unused in the forcedeth driver. It is reported by ifconfig as overruns.
    This change reports rx_drop_frame errors as rx_fifo_errors.

    Function ndo_get_stats() updates most of the stats from hardware
    registers, making the manual updates un-needed. This change removes
    these manual updates. Main exception is rx_missed_errors which needs
    manual update.

    Another exception is rx_packets, still updated manually in this commit
    to make sure this patch doesn't change behavior of driver. This will
    be addressed by a future patch.
