    User namespaces: Only put the userns when we unhash the uid

    Serge E. Hallyn authored torvalds committed
    uids in namespaces other than init don't get a sysfs entry.
    
    For those in the init namespace, while we're waiting to remove
    the sysfs entry for the uid the uid is still hashed, and
    alloc_uid() may re-grab that uid without getting a new
    reference to the user_ns, which we've already put in free_user
    before scheduling remove_user_sysfs_dir().

    ASoC: Only register AC97 bus if it's not done already

    broonie authored
    ASoC supports both explicit codec drivers for AC97 devices and a simple
    driver which uses the standard ALSA AC97 framework for codec support.
    When used with the generic AC97 codec support that will provide the
    ad hoc AC97 device for drivers like touchscreens to attach to so the
    core shouldn't do so.

    ALSA: hda - Add snd_hda_multi_out_dig_cleanup()

    tiwai authored
    Added the helper function snd_hda_multi_out_dig_cleanup() to clean up
    the digital outputs with multi setup.  This call is needed in cases
    the codec supports multiple digital outputs as slaves.  Otherwise the
    slave widgets aren't properly cleaned up.
    
    For a single digital output (e.g. in patch_conexant.c), this call isn't
    needed.

    ALSA: hda - Change HP dv7 (103c:30f4) quirk from hp-m4 to hp-dv5 model

    Herton Ronaldo Krzesinski authored tiwai committed
    Change HP dv7 quirk: although reported to work with hp-m4 model
    (https://bugzilla.novell.com/show_bug.cgi?id=445321), the original
    report doesn't contain info about testing of internal microphone.
    
    Recently I received a report about internal mic not working
    (https://qa.mandriva.com/show_bug.cgi?id=44855#c193), this must be
    related with the forced line in on pin 0x0e done with hp-m4 model. Thus
    change the current quirk from STAC_HP_M4 to STAC_HP_DV5, later reported
    to be fixed on a provided kernel with this change
    (https://qa.mandriva.com/show_bug.cgi?id=44855#c196).

    …imax iface
    
    When a non-wimax interface is looked up by the stack, a bad pointer is
    returned when the looked-up interface is not found in the list (of
    registered WiMAX interfaces). This causes an oops in the caller when
    trying to use the pointer.
    
    Fix by properly setting the pointer to NULL if we don't exit from the
    list_for_each() with a found entry.

    net: 4 bytes kernel memory disclosure in SO_BSDCOMPAT gsopt try #2

    Clément Lecigne authored davem330 committed
    In function sock_getsockopt() located in net/core/sock.c, optval v.val
    is not correctly initialized and directly returned in userland in case
    we have SO_BSDCOMPAT option set.
    
    This dummy code should trigger the bug:
    
    int main(void)
    {
    	unsigned char buf[4] = { 0, 0, 0, 0 };
    	int len;
    	int sock;
    	sock = socket(33, 2, 2);
    	getsockopt(sock, 1, SO_BSDCOMPAT, &buf, &len);
    	printf("%x%x%x%x\n", buf[0], buf[1], buf[2], buf[3]);
    	close(sock);
    }
    
    Here is a patch that fix this bug by initalizing v.val just after its
    declaration.

    net: don't use in_atomic() in gfp_any()

    Andrew Morton authored davem330 committed
    The problem is that in_atomic() will return false inside spinlocks if
    CONFIG_PREEMPT=n.  This will lead to deadlockable GFP_KERNEL allocations
    from spinlocked regions.
    
    Secondly, if CONFIG_PREEMPT=y, this bug solves itself because networking
    will instead use GFP_ATOMIC from this callsite.  Hence we won't get the
    might_sleep() debugging warnings which would have informed us of the buggy
    callsites.
    
    Solve both these problems by switching to in_interrupt().  Now, if someone
    runs a gfp_any() allocation from inside spinlock we will get the warning
    if CONFIG_PREEMPT=y.
    
    I reviewed all callsites and most of them were too complex for my little
    brain and none of them documented their interface requirements.  I have no
    idea what this patch will do.

    Fix page writeback thinko, causing Berkeley DB slowdown

    Nick Piggin authored torvalds committed
    A bug was introduced into write_cache_pages cyclic writeout by commit
    31a1266 ("mm: write_cache_pages cyclic
    fix").  The intention (and comments) is that we should cycle back and
    look for more dirty pages at the beginning of the file if there is no
    more work to be done.
    
    But the !done condition was dropped from the test.  This means that any
    time the page writeout loop breaks (eg.  due to nr_to_write == 0), we
    will set index to 0, then goto again.  This will set done_index to
    index, then find done is set, so will proceed to the end of the
    function.  When updating mapping->writeback_index for cyclic writeout,
    we now use done_index == 0, so we're always cycling back to 0.
    
    This seemed to be causing random mmap writes (slapadd and iozone) to
    start writing more pages from the LRU and writeout would slowdown, and
    caused bugzilla entry
    
    	http://bugzilla.kernel.org/show_bug.cgi?id=12604
    
    about Berkeley DB slowing down dramatically.
    
    With this patch, iozone random write performance is increased nearly
    5x on my system (iozone -B -r 4k -s 64k -s 512m -s 1200m on ext2).
