      Pull networking fixes from David Miller:
      
       1) Fix bluetooth userland regression reported by Keith Packard, from
          Gustavo Padovan.
      
       2) Revert ath9k PS idle change, from Sujith Manoharan.
      
       3) Correct default TCP memory limits (again), from Eric Dumazet.
      
       4) Fix tcp_rcv_rtt_update() accidental use of unscaled RTT, from Neal
          Cardwell.
      
       5) We made a facility for layers like wireless to say how much tailroom
          they need in the SKB for link layer stuff such as wireless
          encryption etc., but TCP works hard to fill every SKB out to the end
          defeating this specification.
      
          This leads to every TCP packet getting reallocated by the wireless
          code in order to have the right amount of tailroom available.
      
          Fix TCP to only fill SKBs out to the real amount of data area it
          asked for during the allocation, this way it won't eat into the
          slack added for the device's tailroom needs.
      
          Reported by Marc Merlin and fixed by Eric Dumazet.
      
       6) Leaks, endian bugs, and new device IDs in bluetooth from Santosh
          Nayak, João Paulo Rechi Vita, Cho, Yu-Chen, Andrei Emeltchenko,
          AceLan Kao, and Andrei Emeltchenko.

       8) netfilter erroneously scales TCP window twice, fix from Changli Gao.
      
       9) Memleak fix in wext-core from Julia Lawall.
      
      10) Consistently handle invalid TCP packets in ipv4 vs.  ipv6 conntrack,
          from Jozsef Kadlecsik.
      
      11) Validate IP header length properly in netfilter conntrack's
          ipv4_get_l4proto().

      panic: fix stack dump print on direct call to panic() · 026ee1f6
      Jason Wessel 提交于
      Commit 6e6f0a1f ("panic: don't print redundant backtraces on oops")
      causes a regression where no stack trace will be printed at all for the
      case where kernel code calls panic() directly while not processing an
      oops, and of course there are 100's of instances of this type of call.
      
      The original commit executed the check (!oops_in_progress), but this will
      always be false because just before the dump_stack() there is a call to
      bust_spinlocks(1), which does the following:
      
        void __attribute__((weak)) bust_spinlocks(int yes)
        {
      	if (yes) {
      		++oops_in_progress;
      
      The proper way to resolve the problem that original commit tried to
      solve is to avoid printing a stack dump from panic() when the either of
      the following conditions is true:
      
        1) TAINT_DIE has been set (this is done by oops_end())
           This indicates and oops has already been printed.
        2) oops_in_progress > 1
           This guards against the rare case where panic() is invoked
           a second time, or in between oops_begin() and oops_end()

      Ying Han 提交于
      This reverts commit c38446cc.
      
      Before the commit, the code makes senses to me but not after the commit.
      The "nr_reclaimed" is the number of pages reclaimed by scanning through
      the memcg's lru lists.  The "nr_to_reclaim" is the target value for the
      whole function.  For example, we like to early break the reclaim if
      reclaimed 32 pages under direct reclaim (not DEF_PRIORITY).
      
      After the reverted commit, the target "nr_to_reclaim" is decremented each
      time by "nr_reclaimed" but we still use it to compare the "nr_reclaimed".
      It just doesn't make sense to me...

      hugetlb: fix race condition in hugetlb_fault() · 66aebce7
      Chris Metcalf 提交于
      The race is as follows:
      
      Suppose a multi-threaded task forks a new process (on cpu A), thus
      bumping up the ref count on all the pages.  While the fork is occurring
      (and thus we have marked all the PTEs as read-only), another thread in
      the original process (on cpu B) tries to write to a huge page, taking an
      access violation from the write-protect and calling hugetlb_cow().  Now,
      suppose the fork() fails.  It will undo the COW and decrement the ref
      count on the pages, so the ref count on the huge page drops back to 1.
      Meanwhile hugetlb_cow() also decrements the ref count by one on the
      original page, since the original address space doesn't need it any
      more, having copied a new page to replace the original page.  This
      leaves the ref count at zero, and when we call unlock_page(), we panic.
      
      	fork on CPU A				fault on CPU B
      	=============				==============
      	...
      	down_write(&parent->mmap_sem);
      	down_write_nested(&child->mmap_sem);
      	...
      	while duplicating vmas
      		if error
      			break;
      	...
      	up_write(&child->mmap_sem);
      	up_write(&parent->mmap_sem);		...
      						down_read(&parent->mmap_sem);
      						...
      						lock_page(page);
      						handle COW
      						page_mapcount(old_page) == 2
      						alloc and prepare new_page
      	...
      	handle error
      	page_remove_rmap(page);
      	put_page(page);
      	...
      						fold new_page into pte
      						page_remove_rmap(page);
      						put_page(page);
      						...
      				oops ==>	unlock_page(page);
      						up_read(&parent->mmap_sem);
      
      The solution is to take an extra reference to the page while we are
      holding the lock on it.

      drivers/rtc/rtc-twl.c: use static register while reading time · f3ec434c
      Konstantin Shlyakhovoy 提交于
      RTC stores time and date in several registers.  Due to the fact that
      these registers can't be read instantaneously, there is a chance that
      reading from counting registers gives an error of one minute, one hour,
      one day, etc.
      
      To address this issue, the RTC has hardware support to copy the RTC
      counting registers to static shadowed registers.  The current
      implementation does not use this feature, and in a stress test, we can
      reproduce this error at a rate of around two times per 300000 readings.
      
      Fix the implementation to ensure that the right snapshot of time is
      captured.

      drivers/char/random.c: fix boot id uniqueness race · 44e4360f
      Mathieu Desnoyers 提交于
      /proc/sys/kernel/random/boot_id can be read concurrently by userspace
      processes.  If two (or more) user-space processes concurrently read
      boot_id when sysctl_bootid is not yet assigned, a race can occur making
      boot_id differ between the reads.  Because the whole point of the boot id
      is to be unique across a kernel execution, fix this by protecting this
      operation with a spinlock.
      
      Given that this operation is not frequently used, hitting the spinlock
      on each call should not be an issue.

      memcg: fix up documentation on global LRU · 6252efcc
      Ying Han 提交于
      In v3.3-rc1, the global LRU was removed in commit 925b7673 ("mm:
      make per-memcg LRU lists exclusive").  The patch fixes up the memcg
      docs.
      
      I left the swap session to someone who has better understanding of
      'memory+swap'.

      Linus Torvalds 提交于
      Pull irqdomain bug fixes from Grant Likely:
       "This branch fixes a bug in irq_create_mapping() where an error return
        from irq_alloc_desc_from() gets ignored.
      
        It also removes irq_virq_count to fix a bug on powerpc where the
        irqdomain code does not find irqs allocated above the CONFIG_NR_IRQS
        boundary.
      
        The remaining patches get rid of an completely pointless export and
        fix some minor bugs in the irqdomain debug output."

      3 regression fixes:
      - disable gmbus again, too broken for 3.4, we'll try again for 3.5
      - dp bandwidth computation fix, we've lost the 6bpc dithering flag
       sometimes, this is a 3.3 regression (maybe even earlier for some
       configurations).
      - fix resume regression caused by the gen2/3 fencing fix merged into -rc2.
      
      And a few other fixes:
      - gpu hang fix for i845 (Chris)
      - sprite fix (Armin Reese)
      - crtc disable vs. scanlinewait race fix (Chris)
      - rc6 module option read-only, it confused testers (Jesse)
      - fbc related blitter death hw workaround, note that we disable fbc on snb
       by default anyway.
      
      With these fixes we have one 3.4 regression outstanding: One of the
      cleanup patches for the interlaced support managed to confuse the lvds
      panel fitter when upscaling. The root-cause is still unclear, but test
      patches are awaiting feedback from the reporter.
