      [PATCH] i386: clear segment register padding in core dumps · 6ea65ff7
      Roland McGrath authored
      The segment register slots in struct pt_regs are padded to 32 bits.
      Some of these are stored with instructions like "pushl %es", which
      leaves the high 16 bits as they were.  So the high bits of these
      fields in struct pt_regs contain kernel stack garbage.  These bits are
      ignored by everything and never leak to user space, except in core
      dumps.  The user struct pt_regs is always at the base of the thread's
      kernel stack and so it seems unlikely the information that leaks from
      here is ever worthwhile so as to be a security concern, but I'm not
      sure about that.  It has been this way for ages; userland consumers of
      core dumps all mask off these high bits themselves.  So it is not urgent.
      
      This change masks off the padding bits of the segment register slots
      in core dumps.  ptrace already masks off these high bits, so this
      makes the values in core dumps consistent with what ptrace would
      report just before the process died.
      
      As I read the processor manuals, the cs and ss values will always be
      padded with zero bits rather than stack garbage.  But unlike "pushl %es",
      this is not simple to test with a userland program.  So I added the two
      instructions rather than wonder if they are really never necessary.
      
      I think that x86_64 does not have this problem (for either 32-bit or
      64-bit processes).  It only uses "mov" instructions from segment
      registers, which zero-extend.

      [PATCH] FDPIC: fix the /proc/pid/stat representation of executable boundaries · aa289b47
      David Howells authored
      Fix the /proc/pid/stat representation of executable boundaries.  It should
      show the bounds of the executable, but instead shows the bounds of the
      loader.
      
      Before the patch is applied, the bug can be seen by examining, say, inetd:
      
      	# ps | grep inetd
      	  610         root          0   S   /usr/sbin/inetd -i
      	# cat /proc/610/maps
      	c0bb0000-c0bba788 r-xs 00000000 00:0b 14582157  /lib/ld-uClibc-0.9.28.so
      	c3180000-c31dede4 r-xs 00000000 00:0b 14582179  /lib/libuClibc-0.9.28.so
      	c328c000-c328ea00 rw-p 00008000 00:0b 14582157  /lib/ld-uClibc-0.9.28.so

      	c34d4000-c34d8000 rw-p 00000000 00:00 0

      	# cat /proc/610/stat
      	610 (inetd) S 1 610 610 0 -1 256 0 0 0 0 0 8 0 0 19 0 1 0 94392000718
      	950272 0 4294967295 3233480704 3233523592 3274440352 3274439976
       	3273467584 0 0 4096 90115 3221712796 0 0 17 0 0 0 0
      
      The code boundaries are 3233480704 to 3233523592, which are:
      
      	(gdb) p/x 3233480704
      	$1 = 0xc0bb0000
      	(gdb) p/x 3233523592
      	$2 = 0xc0bba788
      
      Which corresponds to this line in the maps file:
      
      	c0bb0000-c0bba788 r-xs 00000000 00:0b 14582157  /lib/ld-uClibc-0.9.28.so
      
      Which is wrong.  After the patch is applied, the maps file is pretty much
      identical (there's some minor shuffling of the location of some of the
      anonymous VMAs), but the stat file is now:
      
      	# cat /proc/610/stat
      	610 (inetd) S 1 610 610 0 -1 256 0 0 0 0 0 7 0 0 18 0 1 0 94392000722
      	950272 0 4294967295 3276111872 3276141668 3274440352 3274439976
      	3273467584 0 0 4096 90115 3221712796 0 0 17 0 0 0 0
      
      The code boundaries are then 3276111872 to 3276141668, which are:
      
      	(gdb) p/x 3276111872
      	$1 = 0xc3458000
      	(gdb) p/x 3276141668
      	$2 = 0xc345f464
      
      And these correspond to this line in the maps file instead:
      
      	c3458000-c345f464 r-xs 00000000 00:0b 16384612  /usr/sbin/inetd
      
      Which is now correct.

      [PATCH] i386: add command line option "local_apic_timer_c2_ok" · e585bef8
      Thomas Gleixner authored
      It turned out that it is almost impossible to trust ACPI, BIOS & Co.
      regarding the C states. This was the reason to switch the local apic
      timer off in C2 state already. OTOH there are sane and well behaving
      systems, which get punished by that decision.
      
      Allow the user to confirm that the local apic timer is trustworthy in C2
      state. This keeps the default behaviour on the safe side.

      Revert "ucc_geth: returns NETDEV_TX_BUSY when BD ring is full" · 6f6881b8
      Li Yang authored
      This reverts commit 18babd38.
      
      Michael Barkowski points out that it's wrong, and I agree.  The
      patch causes a problem rather than fixes one after another
      patch "ucc_geth: Fix BD processing" was applied.  Before that
      patch, current packet should be blocked.  However after the patch
      current packet is ok and we only need to block next.

      cxgb3 - Fix potential MAC hang · fc90664e
      Divy Le Ray authored
      Under rare conditions, the MAC might hang while generating a pause frame.
      This patch fine tunes the MAC settings to avoid the issue, allows for
      periodic MAC state check, and triggers a recovery if hung.
      
      Also fix one MAC statistics counter for the rev board T3B2.
