    I guess it should return -EADDRNOTAVAIL similar to eth_mac_addr()
    when validation fails.

  • 7ffc49a6e   [ETH]: Combine format_addr() with print_mac(). ... Browse Code »

    print_mac() used many most net drivers and format_addr() used by
    net-sysfs.c are very similar and they can be intergrated.

    format_addr() is also identically redefined in the qla4xxx iscsi
    driver.

    Export a new function sysfs_format_mac() to be used by net-sysfs,
    qla4xxx and others in the future. Both print_mac() and
    sysfs_format_mac() call _format_mac_addr() to do the formatting.

    Changed print_mac() to use unsigned char * to be consistent with
    net_device struct's dev_addr. Added buffer length overrun checking
    as suggested by Joe Perches.

  • f25f4e448   [CORE] Stack changes to add multiqueue hardware support API ... Browse Code »

    Add the multiqueue hardware device support API to the core network
    stack. Allow drivers to allocate multiple queues and manage them at
    the netdev level if they choose to do so.

    Added a new field to sk_buff, namely queue_mapping, for drivers to
    know which tx_ring to select based on OS classification of the flow.

  • cd354f1ae   [PATCH] remove many unneeded #includes of sched.h ... Browse Code »

    After Al Viro (finally) succeeded in removing the sched.h #include in module.h
    recently, it makes sense again to remove other superfluous sched.h includes.
    There are quite a lot of files which include it but don't actually need
    anything defined in there. Presumably these includes were once needed for
    macros that used to live in sched.h, but moved to other header files in the
    course of cleaning it up.

    To ease the pain, this time I did not fiddle with any header files and only
    removed #includes from .c-files, which tend to cause less trouble.

    Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha,
    arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig,
    allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all
    configs in arch/arm/configs on arm. I also checked that no new warnings were
    introduced by the patch (actually, some warnings are removed that were emitted
    by unnecessarily included header files).

  • f8d0e3f11   [NET] ethernet: Fix first packet goes out with MAC 00:00:00:00:00:00 ... Browse Code »

    When you turn off ARP on a netdevice then the first packet always goes
    out with a dstMAC of all zeroes. This is because the first packet is
    used to resolve ARP entries. Even though the ARP entry may be resolved
    (I tried by setting a static ARP entry for a host i was pinging from),
    it gets overwritten by virtue of having the netdevice disabling ARP.

    Subsequent packets go out fine with correct dstMAC address (which may
    be why people have ignored reporting this issue).

    To cut the story short:

    the culprit code is in net/ethernet/eth.c::eth_header()

    ----
    /*
    * Anyway, the loopback-device should never use this
    function...
    */

    if (dev->flags & (IFF_LOOPBACK|IFF_NOARP))
    {
    memset(eth->h_dest, 0, dev->addr_len);
    return ETH_HLEN;
    }

    if(daddr)
    {
    memcpy(eth->h_dest,daddr,dev->addr_len);
    return ETH_HLEN;
    }

    ----

    Note how the h_dest is being reset when device has IFF_NOARP.

    As a note:
    All devices including loopback pass a daddr. loopback in fact passes
    a 0 all the time ;->
    This means i can delete the check totaly or i can remove the IFF_NOARP

    Alexey says:
    --------------------
    I think, it was me who did this crap. It was so long ago I do not remember
    why it was made.

    I remember some troubles with dummy device. It tried to resolve
    addresses, apparently, without success and generated errors instead of
    blackholing. I think the problem was eventually solved at neighbour
    level.

    After some thinking I suspect the deletion of this chunk could change
    behaviour of some parts which do not use neighbour cache f.e. packet
    socket.

    I think safer approach would be to move this chunk after if (daddr).
    And the possibility to remove this completely could be analyzed later.
    --------------------

    Patch updated with Alexey's safer suggestions.

  • 1da177e4c   Linux-2.6.12-rc2 ... Browse Code »

    Initial git repository build. I'm not bothering with the full history,
    even though we have it. We can create a separate "historical" git
    archive of that later if we want to, and in the meantime it's about
    3.2GB when imported into git - space that would just make the early
    git days unnecessarily complicated, when we don't have a lot of good
    infrastructure for it.

    Let it rip!
