      x86/asm/entry/irq: Simplify interrupt dispatch table (IDT) layout · 3304c9c3
      Denys Vlasenko authored
      Interrupt entry points are handled with the following code,
      each 32-byte code block contains seven entry points:
      
      		...
      		[push][jump 22] // 4 bytes
      		[push][jump 18] // 4 bytes
      		[push][jump 14] // 4 bytes
      		[push][jump 10] // 4 bytes
      		[push][jump  6] // 4 bytes
      		[push][jump  2] // 4 bytes
      		[push][jump common_interrupt][padding] // 8 bytes
      
      		[push][jump]
      		[push][jump]
      		[push][jump]
      		[push][jump]
      		[push][jump]
      		[push][jump]
      		[push][jump common_interrupt][padding]
      
      		[padding_2]
      	common_interrupt:
      
      And there is a table which holds pointers to every entry point,
      IOW: to every push.
      
      In cold cache, two jumps are still costlier than one, even
      though we get the benefit of them residing in the same
      cacheline.
      
      This change replaces short jumps with near ones to
      'common_interrupt', and pads every push+jump pair to 8 bytes. This
      way, each interrupt takes only one jump.
      
      This change replaces ".p2align CONFIG_X86_L1_CACHE_SHIFT" before
      dispatch table with ".align 8" - we do not need anything
      stronger than that.
      
      The table of entry addresses (the interrupt[] array) is no
      longer necessary, the address of entries can be easily
      calculated as (irq_entries_start + i*8).
      
         text	   data	    bss	    dec	    hex	filename
        12546	      0	      0	  12546	   3102	entry_64.o.before
        11626	      0	      0	  11626	   2d6a	entry_64.o
      
      The size decrease is because 1656 bytes of .init.rodata are
      gone. That's initdata, though. The resident size does go up a
      bit.
      
      Run-tested (32 and 64 bits).

      x86/asm/entry/64: Move opportunistic sysret code to syscall code path · fffbb5dc
      Denys Vlasenko authored
      This change does two things:
      
      Copy-pastes "retint_swapgs:" code into syscall handling code,
      the copy is under "syscall_return:" label. The code is unchanged
      apart from some label renames.
      
      Removes "opportunistic sysret" code from "retint_swapgs:" code
      block, since now it won't be reached by syscall return. This in
      fact removes most of the code in question.

      x86, selftests: Add sigreturn selftest · 3f705dfd
      Andy Lutomirski authored
      This is my sigreturn test, added mostly unchanged from its old
      home. It exercises the sigreturn(2) syscall, specifically
      focusing on its interactions with various IRET corner cases.
      
      It tests for correct behavior in several areas that were
      historically dangerously buggy. For example, it exercises espfix
      on kernels of both bitnesses under various conditions, and it
      contains testcases for several now-fixed bugs in IRET error
      handling.
      
      If you run it on older kernels without the fixes, your system will
      crash. It probably won't eat your data in the process.
      
      There is no released kernel on which the sigreturn_64 test will
      pass, but it passes on tip:x86/asm.
      
      I plan to switch to lib.mk for Linux 4.2.
      
      I'm not using the ksft_ helpers at all yet.  I can do that later.

      Pull networking fixes from David Miller:
      
       1) In TCP, don't register an FRTO for cumulatively ACK'd data that was
          previously SACK'd, from Neal Cardwell.
      
       2) Need to hold RNL mutex in ipv4 multicast code namespace cleanup,
          from Cong WANG.
      
       3) Similarly we have to hold RNL mutex for fib_rules_unregister(), also
          from Cong WANG.
      
       4) Revert and rework netns nsid allocation fix, from Nicolas Dichtel.
      
       5) When we encapsulate for a tunnel device, skb->sk still points to the
          user socket.  So this leads to cases where we retraverse the
          ipv4/ipv6 output path with skb->sk being of some other address
          family (f.e. AF_PACKET).  This can cause things to crash since the
          ipv4 output path is dereferencing an AF_PACKET socket as if it were
          an ipv4 one.
      
          The short term fix for 'net' and -stable is to elide these socket
          checks once we've entered an encapsulation sequence by testing
          xmit_recursion.
      
          Longer term we have a better solution wherein we pass the tunnel's
          socket down through the output paths, but that is way too invasive
          for 'net' and -stable.
      
          From Hannes Frederic Sowa.
      
       6) l2tp_init() failure path forgets to unregister per-net ops, from
          Cong WANG.

      net: dsa: fix filling routing table from OF description · 30303813
      Pavel Nakonechny authored
      According to description in 'include/net/dsa.h', in cascade switches
      configurations where there are more than one interconnected devices,
      'rtable' array in 'dsa_chip_data' structure is used to indicate which
      port on this switch should be used to send packets to that are destined
      for corresponding switch.
      
      However, dsa_of_setup_routing_table() fills 'rtable' with port numbers
      of the _target_ switch, but not current one.
      
      This commit removes redundant devicetree parsing and adds needed port
      number as a function argument. So dsa_of_setup_routing_table() now just
      looks for target switch number by parsing parent of 'link' device node.
      
      To remove possible misunderstandings with the way of determining target
      switch number, a corresponding comment was added to the source code and
      to the DSA device tree bindings documentation file.
      
      This was tested on a custom board with two Marvell 88E6095 switches with
      following corresponding routing tables: { -1, 10 } and { 8, -1 }.

      ipv6: protect skb->sk accesses from recursive dereference inside the stack · f60e5990
      hannes@stressinduktion.org authored
      We should not consult skb->sk for output decisions in xmit recursion
      levels > 0 in the stack. Otherwise local socket settings could influence
      the result of e.g. tunnel encapsulation process.
      
      ipv6 does not conform with this in three places:
      
      1) ip6_fragment: we do consult ipv6_npinfo for frag_size
      
      2) sk_mc_loop in ipv6 uses skb->sk and checks if we should
         loop the packet back to the local socket
      
      3) ip6_skb_dst_mtu could query the settings from the user socket and
         force a wrong MTU
      
      Furthermore:
      In sk_mc_loop we could potentially land in WARN_ON(1) if we use a
      PF_PACKET socket ontop of an IPv6-backed vxlan device.
      
      Reuse xmit_recursion as we are currently only interested in protecting
      tunnel devices.

      x86/alternatives: Guard NOPs optimization · 69df353f
      Borislav Petkov authored
      Take a look at the first instruction byte before optimizing the NOP -
      there might be something else there already, like the ALTERNATIVE_2()
      in rdtsc_barrier() which NOPs out on AMD even though we just
      patched in an MFENCE.
      
      This happens because the alternatives sees X86_FEATURE_MFENCE_RDTSC,
      AMD CPUs set it, we patch in the MFENCE and right afterwards it sees
      X86_FEATURE_LFENCE_RDTSC which AMD CPUs don't set and we blindly
      optimize the NOP.
      
      Checking whether at least the first byte is 0x90 prevents that.

      x86/asm/entry: Clear EXTRA_REGS for all executable formats · fc3e958a
      Denys Vlasenko authored
      On failure, sys_execve() does not clobber EXTRA_REGS, so we can
      just return to userpsace without saving/restoring them.
      
      On success, ELF_PLAT_INIT() in sys_execve() clears all these
      registers.
      
      On other executable formats:
      
        - binfmt_flat.c has similar FLAT_PLAT_INIT, but x86 (and everyone
          else except sh) doesn't define it.
      
        - binfmt_elf_fdpic.c has ELF_FDPIC_PLAT_INIT, but x86 (and most
          others) doesn't define it.
      
        - There are no such hooks in binfmt_aout.c et al. We inherit
          EXTRA_REGS from the prior executable.
      
      This inconsistency was not intended.
      
      This change removes SAVE/RESTORE_EXTRA_REGS in stub_execve,
      removes register clearing in ELF_PLAT_INIT(),
      and instead simply clears them on success in stub_execve.
      
      Run-tested.

      x86/signal: Remove pax argument from restore_sigcontext · 6a3713f0
      Brian Gerst authored
      The 'pax' argument is unnecesary.  Instead, store the RAX value
      directly in regs.
      
      This pattern goes all the way back to 2.1.106pre1, when restore_sigcontext()
      was changed to return an error code instead of EAX directly:
      
        https://git.kernel.org/cgit/linux/kernel/git/history/history.git/diff/arch/i386/kernel/signal.c?id=9a8f8b7ca3f319bd668298d447bdf32730e51174
      
      In 2007 sigaltstack syscall support was added, where the return
      value of restore_sigcontext() was changed to carry the memory-copying
      failure code.
      
      But instead of putting 'ax' into regs->ax directly, it was carried
      in via a pointer and then returned, where the generic syscall return
      code copied it to regs->ax.
      
      So there was never any deeper reason for this suboptimal pattern, it
      was simply never noticed after being introduced.

      x86/alternatives: Fix ALTERNATIVE_2 padding generation properly · dbe4058a
      Borislav Petkov authored
      Quentin caught a corner case with the generation of instruction
      padding in the ALTERNATIVE_2 macro: if len(orig_insn) <
      len(alt1) < len(alt2), then not enough padding gets added and
      that is not good(tm) as we could overwrite the beginning of the
      next instruction.
      
      Luckily, at the time of this writing, we don't have
      ALTERNATIVE_2() invocations which have that problem and even if
      we did, a simple fix would be to prepend the instructions with
      enough prefixes so that that corner case doesn't happen.
      
      However, best it would be if we fixed it properly. See below for
      a simple, abstracted example of what we're doing.
      
      So what we ended up doing is, we compute the
      
      	max(len(alt1), len(alt2)) - len(orig_insn)
      
      and feed that value to the .skip gas directive. The max() cannot
      have conditionals due to gas limitations, thus the fancy integer
      math.
      
      With this patch, all ALTERNATIVE_2 sites get padded correctly;
      generating obscure test cases pass too:
      
        #define alt_max_short(a, b)    ((a) ^ (((a) ^ (b)) & -(-((a) < (b)))))
      
        #define gen_skip(orig, alt1, alt2, marker)	\
        	.skip -((alt_max_short(alt1, alt2) - (orig)) > 0) * \
        		(alt_max_short(alt1, alt2) - (orig)),marker
      
        	.pushsection .text, "ax"
        .globl main
        main:
        	gen_skip(1, 2, 4, 0x09)
        	gen_skip(4, 1, 2, 0x10)
        	...
        	.popsection
      
      Thanks to Quentin for catching it and double-checking the fix!
