      Correct Makefile rule for generating custom keymap · e2a57a81
      Maarten Bressers authored
      When building a custom keymap, after setting GENERATE_KEYMAP := 1 in
      drivers/char/Makefile, the kernel build fails like this:
          CC      drivers/char/vt.o
        make[2]: *** No rule to make target `drivers/char/%.map', needed by `drivers/char/defkeymap.c'.  Stop.
        make[1]: *** [drivers/char] Error 2
        make: *** [drivers] Error 2
      This was caused by commit af8b1287
      , which
      deleted a necessary colon from the Makefile rule that generates the keymap,
      since that rule contains both a target and a target-pattern.  The following
      patch puts the colon back:

      When IOCB_FLAG_RESFD flag is set and iocb->aio_resfd is incorrect,
      statement 'goto out_put_req' is executed. At label 'out_put_req',
      aio_put_req(..) is called, which requires 'req->ki_filp' set.

      mm: set_page_dirty_balance() vs ->page_mkwrite() · a200ee18
      Peter Zijlstra authored
      All the current page_mkwrite() implementations also set the page dirty. Which
      results in the set_page_dirty_balance() call to _not_ call balance, because the
      page is already found dirty.
      This allows us to dirty a _lot_ of pages without ever hitting
      balance_dirty_pages().  Not good (tm).
      Force a balance call if ->page_mkwrite() was successful.

      [IPv6]: Fix ICMPv6 redirect handling with target multicast address · bf0b48df
      Brian Haley authored
      When the ICMPv6 Target address is multicast, Linux processes the 
      redirect instead of dropping it.  The problem is in this code in 
               if (ipv6_addr_equal(dest, target)) {
                       on_link = 1;
               } else if (!(ipv6_addr_type(target) & IPV6_ADDR_LINKLOCAL)) {
                                  "ICMPv6 Redirect: target address is not 
      This second check will succeed if the Target address is, for example, 
      FF02::1 because it has link-local scope.  Instead, it should be checking 
      if it's a unicast link-local address, as stated in RFC 2461/4861 Section 
             - The ICMP Target Address is either a link-local address (when
               redirected to a router) or the same as the ICMP Destination
               Address (when redirected to the on-link destination).
      I know this doesn't explicitly say unicast link-local address, but it's 
      This bug is preventing Linux kernels from achieving IPv6 Logo Phase II 
      certification because of a recent error that was found in the TAHI test 
      suite - Neighbor Disovery suite test 206 (v6LC.2.3.6_G) had the 
      multicast address in the Destination field instead of Target field, so 
      we were passing the test.  This won't be the case anymore.
      The patch below fixes this problem, and also fixes ndisc_send_redirect() 
      to not send an invalid redirect with a multicast address in the Target 
      field.  I re-ran the TAHI Neighbor Discovery section to make sure Linux 
      passes all 245 tests now.

      [TCP]: Fix fastpath_cnt_hint when GSO skb is partially ACKed · 48611c47
      Ilpo Järvinen authored
      When only GSO skb was partially ACKed, no hints are reset,
      therefore fastpath_cnt_hint must be tweaked too or else it can
      corrupt fackets_out. The corruption to occur, one must have
      non-trivial ACK/SACK sequence, so this bug is not very often
      that harmful. There's a fackets_out state reset in TCP because
      fackets_out is known to be inaccurate and that fixes the issue
      eventually anyway.
      In case there was also at least one skb that got fully ACKed,
      the fastpath_skb_hint is set to NULL which causes a recount for
      fastpath_cnt_hint (the old value won't be accessed anymore),
      thus it can safely be decremented without additional checking.
