      mm: don't try to NUMA-migrate COW pages that have other uses · 80d47f5d
      Linus Torvalds authored
      Oded Gabbay reports that enabling NUMA balancing causes corruption with
      his Gaudi accelerator test load:
      
       "All the details are in the bug, but the bottom line is that somehow,
        this patch causes corruption when the numa balancing feature is
        enabled AND we don't use process affinity AND we use GUP to pin pages
        so our accelerator can DMA to/from system memory.
      
        Either disabling numa balancing, using process affinity to bind to
        specific numa-node or reverting this patch causes the bug to
        disappear"
      
      and Oded bisected the issue to commit 09854ba9 ("mm: do_wp_page()
      simplification").
      
      Now, the NUMA balancing shouldn't actually be changing the writability
      of a page, and as such shouldn't matter for COW.  But it appears it
      does.  Suspicious.
      
      However, regardless of that, the condition for enabling NUMA faults in
      change_pte_range() is nonsensical.  It uses "page_mapcount(page)" to
      decide if a COW page should be NUMA-protected or not, and that makes
      absolutely no sense.
      
      The number of mappings a page has is irrelevant: not only does GUP get a
      reference to a page as in Oded's case, but the other mappings migth be
      paged out and the only reference to them would be in the page count.
      
      Since we should never try to NUMA-balance a page that we can't move
      anyway due to other references, just fix the code to use 'page_count()'.
      Oded confirms that that fixes his issue.
      
      Now, this does imply that something in NUMA balancing ends up changing
      page protections (other than the obvious one of making the page
      inaccessible to get the NUMA faulting information).  Otherwise the COW
      simplification wouldn't matter - since doing the GUP on the page would
      make sure it's writable.
      
      The cause of that permission change would be good to figure out too,
      since it clearly results in spurious COW events - but fixing the
      nonsensical test that just happened to work before is obviously the
      CorrectThing(tm) to do regardless.

      tty: n_tty: do not look ahead for EOL character past the end of the buffer · 35930307
      Linus Torvalds authored
      Daniel Gibson reports that the n_tty code gets line termination wrong in
      very specific cases:
      
       "If you feed a line with exactly 64 chars + terminating newline, and
        directly afterwards (without reading) another line into a pseudo
        terminal, the the first read() on the other side will return the 64
        char line *without* terminating newline, and the next read() will
        return the missing terminating newline AND the complete next line (if
        it fits in the buffer)"
      
      and bisected the behavior to commit 3b830a9c ("tty: convert
      tty_ldisc_ops 'read()' function to take a kernel pointer").
      
      Now, digging deeper, it turns out that the behavior isn't exactly new:
      what changed in commit 3b830a9c was that the tty line discipline
      .read() function is now passed an intermediate kernel buffer rather than
      the final user space buffer.
      
      And that intermediate kernel buffer is 64 bytes in size - thus that
      special case with exactly 64 bytes plus terminating newline.
      
      The same problem did exist before, but historically the boundary was not
      the 64-byte chunk, but the user-supplied buffer size, which is obviously
      generally bigger (and potentially bigger than N_TTY_BUF_SIZE, which
      would hide the issue entirely).
      
      The reason is that the n_tty canon_copy_from_read_buf() code would look
      ahead for the EOL character one byte further than it would actually
      copy.  It would then decide that it had found the terminator, and unmark
      it as an EOL character - which in turn explains why the next read
      wouldn't then be terminated by it.
      
      Now, the reason it did all this in the first place is related to some
      historical and pretty obscure EOF behavior, see commit ac8f3bf8
      ("n_tty: Fix poll() after buffer-limited eof push read") and commit
      40d5e090 ("n_tty: Fix EOF push handling").
      
      And the reason for the EOL confusion is that we treat EOF as a special
      EOL condition, with the EOL character being NUL (aka "__DISABLED_CHAR"
      in the kernel sources).
      
      So that EOF look-ahead also affects the normal EOL handling.
      
      This patch just removes the look-ahead that causes problems, because EOL
      is much more critical than the historical "EOF in the middle of a line
      that coincides with the end of the buffer" handling ever was.
      
      Now, it is possible that we should indeed re-introduce the "look at next
      character to see if it's a EOF" behavior, but if so, that should be done
      not at the kernel buffer chunk boundary in canon_copy_from_read_buf(),
      but at a higher level, when we run out of the user buffer.
      
      In particular, the place to do that would be at the top of
      'n_tty_read()', where we check if it's a continuation of a previously
      started read, and there is no more buffer space left, we could decide to
      just eat the __DISABLED_CHAR at that point.
      
      But that would be a separate patch, because I suspect nobody actually
      cares, and I'd like to get a report about it before bothering.

      Linus Torvalds authored
      Pull seccomp fixes from Kees Cook:
       "This fixes a corner case of fatal SIGSYS being ignored since v5.15.
        Along with the signal fix is a change to seccomp so that seeing
        another syscall after a fatal filter result will cause seccomp to kill
        the process harder.
      
        Summary:
      
         - Force HANDLER_EXIT even for SIGNAL_UNKILLABLE
      
         - Make seccomp self-destruct after fatal filter results

      kconfig: fix failing to generate auto.conf · 1b9e740a
      Jing Leng authored
      When the KCONFIG_AUTOCONFIG is specified (e.g. export \
      KCONFIG_AUTOCONFIG=output/config/auto.conf), the directory of
      include/config/ will not be created, so kconfig can't create deps
      files in it and auto.conf can't be generated.
