  • 21f644f3e   [NET]: Undo code bloat in hot paths due to print_mac(). ... Browse Code »

    If print_mac() is used inside of a pr_debug() the compiler
    can't see that the call is redundant so still performs it
    even of pr_debug() ends up being a nop.

    So don't use print_mac() in such cases in hot code paths,
    use MAC_FMT et al. instead.

    As noted by Joe Perches, pr_debug() could be modified to
    handle this better, but that is a change to an interface
    used by the entire kernel and thus needs to be validated
    carefully. This here is thus the less risky fix for
    2.6.25

  • 92468c53c   ieee80211: Stop net_ratelimit/IEEE80211_DEBUG_DROP log pollution ... Browse Code »

    if (net_ratelimit())
    IEEE80211_DEBUG_DROP(...)

    can pollute the logs with messages like:

    printk: 1 messages suppressed.
    printk: 2 messages suppressed.
    printk: 7 messages suppressed.

    if debugging information is disabled. These messages are printed by
    net_ratelimit(). Add a wrapper to net_ratelimit() that takes into account
    the log level, so that net_ratelimit() is called only when we really want
    to print something.

  • 94e10bfb8   softmac: fix wext MLME request reason code endianness ... Browse Code »

    The MLME request reason code is host-endian and our passing
    it to the low level functions is host-endian as well since
    they do the swapping. I noticed that the reason code 768 was
    sent (0x300) rather than 3 when wpa_supplicant terminates.
    This removes the superfluous cpu_to_le16() call.

  • 642f14903   SG: Change sg_set_page() to take length and offset argument ... Browse Code »

    Most drivers need to set length and offset as well, so may as well fold
    those three lines into one.

    Add sg_assign_page() for those two locations that only needed to set
    the page, where the offset/length is set outside of the function context.

    converted many files to use the scatter gather helpers without ensuring
    that the necessary headerfile is included. This
    happened to work for ia64, powerpc, sparc64 and x86 because they
    happened to drag in that file via their .

    On most of the others this probably broke.

    Instead of increasing the header file spider web I choose to include
    directly into the affectes files.

  • 501d857ec   [IEEE80211]: Fix softmac lockdep reports. ... Browse Code »

    It seems I was actually able to hit this deadlock, on my quad G5 softmac
    locks up more often than not. This fixes it by using an own workqueue
    that can safely be flushed under RTNL.

    Not sure if the patch is correct with the workqueue naming. And don't
    think with the patch it doesn't continually lock up. It still does, just
    doesn't invoke lockdep warnings all the time.

  • 457c4cbc5   [NET]: Make /proc/net per network namespace ... Browse Code »

    This patch makes /proc/net per network namespace. It modifies the global
    variables proc_net and proc_net_stat to be per network namespace.
    The proc_net file helpers are modified to take a network namespace argument,
    and all of their callers are fixed to pass &init_net for that argument.
    This ensures that all of the /proc/net files are only visible and
    usable in the initial network namespace until the code behind them
    has been updated to be handle multiple network namespaces.

    Making /proc/net per namespace is necessary as at least some files
    in /proc/net depend upon the set of network devices which is per
    network namespace, and even more files in /proc/net have contents
    that are relevant to a single network namespace.

    Hopefully captured all single statement cases under net/. I'm
    not too sure if there is some policy about #includes that are
    "guaranteed" (ie., in the current tree) to be available through
    some other #included header, so I just added linux/kernel.h to
    each changed file that didn't #include it previously.

    Reported by Chris Evans :

    > The summary is that an evil 80211 frame can crash out a victim's
    > machine. It only applies to drivers using the 80211 wireless code, and
    > only then to certain drivers (and even then depends on a card's
    > firmware not dropping a dubious packet). I must confess I'm not

    > stacks etc.
    >
    > Details are as follows:
    >
    > ieee80211_rx() does not explicitly check that "skb->len >= hdrlen".
    > There are other skb->len checks, but not enough to prevent a subtle
    > off-by-two error if the frame has the IEEE80211_STYPE_QOS_DATA flag
    > set.

    Commit 4cf92a3c was submitted as a fix for bug #8686 at bugzilla.kernel.org
    (http://bugzilla.kernel.org/show_bug.cgi?id=8686). Unfortunately, the fix led to
    a new bug, reported by Yoshifuji Hideaki, that prevented association for WEP
    encrypted networks that use ifconfig to control the device. This patch effectively
    reverts the earlier commit and does a proper fix for bug #8686.

    Victor Porton reported that the SoftMAC layer had random problem when setting the ESSID :
    http://bugzilla.kernel.org/show_bug.cgi?id=8686 After investigation, it turned out to be
    worse, the SoftMAC layer is left in an inconsistent state. The fix is pretty trivial.
