      Pull f2fs updates from Jaegeuk Kim:
       "In this cycle, we've mainly investigated the zoned block device
        support along with patches such as correcting write pointers between
        f2fs and storage, adding asynchronous zone reset flow, and managing
        the number of open zones.
      
        Other than them, f2fs adds another mount option, "errors=x" to specify
        how to handle when it detects an unexpected behavior at runtime.
      
        Enhancements:
         - support 'errors=remount-ro|continue|panic' mount option
         - enforce some inode flag policies
         - allow .tmp compression given extensions
         - add some ioctls to manage the f2fs compression
         - improve looped node chain flow
         - avoid issuing small-sized discard commands during checkpoint
         - implement an asynchronous zone reset
      
        Bug fixes:
         - fix deadlock in xattr and inode page lock
         - fix and add sanity check in some error paths
         - fix to avoid NULL pointer dereference f2fs_write_end_io() along
           with put_super
         - set proper flags to quota files
         - fix potential deadlock due to unpaired node_write lock use
         - fix over-estimating free section during FG GC
         - fix the wrong condition to determine atomic context
      
        As usual, also there are a number of patches with code refactoring and
        minor clean-ups"

      nfp: clean mc addresses in application firmware when closing port · cc7eab25
      Yinjun Zhang authored
      When moving devices from one namespace to another, mc addresses are
      cleaned in software while not removed from application firmware. Thus
      the mc addresses are remained and will cause resource leak.
      
      Now use `__dev_mc_unsync` to clean mc addresses when closing port.
      
      Fixes: e20aa071 ("nfp: fix schedule in atomic context when sync mc address")

      gup: make the stack expansion warning a bit more targeted · 6cd06ab1
      Linus Torvalds authored
      I added a warning about about GUP no longer expanding the stack in
      commit a425ac53 ("gup: add warning if some caller would seem to want
      stack expansion"), but didn't really expect anybody to hit it.
      
      And it's true that nobody seems to have hit a _real_ case yet, but we
      certainly have a number of reports of false positives.  Which not only
      causes extra noise in itself, but might also end up hiding any real
      cases if they do exist.
      
      So let's tighten up the warning condition, and replace the simplistic
      
      	vma = find_vma(mm, start);
      	if (vma && (start < vma->vm_start)) {
      		WARN_ON_ONCE(vma->vm_flags & VM_GROWSDOWN);
      
      with a
      
      	vma = gup_vma_lookup(mm, start);
      
      helper function which works otherwise like just "vma_lookup()", but with
      some heuristics for when to warn about gup no longer causing stack
      expansion.
      
      In particular, don't just warn for "below the stack", but warn if it's
      _just_ below the stack (with "just below" arbitrarily defined as 64kB,
      because why not?).  And rate-limit it to at most once per hour, which
      means that any false positives shouldn't completely hide subsequent
      reports, but we won't be flooding the logs about it either.
      
      The previous code triggered when some GUP user (chromium crashpad)
      accessing past the end of the previous vma, for example.  That has never
      expanded the stack, it just causes GUP to return early, and as such we
      shouldn't be warning about it.
      
      This is still going trigger the randomized testers, but to mitigate the
      noise from that, use "dump_stack()" instead of "WARN_ON_ONCE()" to get
      the kernel call chain.  We'll get the relevant information, but syzbot
      shouldn't get too upset about it.
      
      Also, don't even bother with the GROWSUP case, which would be using
      different heuristics entirely, but only happens on parisc.

      ====================
      mptcp: fixes for v6.5
      
      Here is a first batch of fixes for v6.5 and older.
      
      The fixes are not linked to each others.
      
      Patch 1 ensures subflows are unhashed before cleaning the backlog to
      avoid races. This fixes another recent fix from v6.4.
      
      Patch 2 does not rely on implicit state check in mptcp_listen() to avoid
      races when receiving an MP_FASTCLOSE. A regression from v5.17.
      
      The rest fixes issues in the selftests.
      
      Patch 3 makes sure errors when setting up the environment are no longer
      ignored. For v5.17+.
      
      Patch 4 uses 'iptables-legacy' if available to be able to run on older
      kernels. A fix for v5.13 and newer.
      
      Patch 5 catches errors when issues are detected with packet marks. Also
      for v5.13+.
      
      Patch 6 uses the correct variable instead of an undefined one. Even if
      there was no visible impact, it can help to find regressions later. An
      issue visible in v5.19+.
      
      Patch 7 makes sure errors with some sub-tests are reported to have the
      selftest marked as failed as expected. Also for v5.19+.
      
      Patch 8 adds a kernel config that is required to execute MPTCP
      selftests. It is valid for v5.9+.
      
      Patch 9 fixes issues when validating the userspace path-manager with
      32-bit arch, an issue affecting v5.19+.

      selftests: mptcp: pm_nl_ctl: fix 32-bit support · 61d96580
      Matthieu Baerts authored
      When using pm_nl_ctl to validate userspace path-manager's behaviours, it
      was failing on 32-bit architectures ~half of the time.
      
      pm_nl_ctl was not reporting any error but the command was not doing what
      it was expected to do. As a result, the expected linked event was not
      triggered after and the test failed.
      
      This is due to the fact the token given in argument to the application
      was parsed as an integer with atoi(): in a 32-bit arch, if the number
      was bigger than INT_MAX, 2147483647 was used instead.
      
      This can simply be fixed by using strtoul() instead of atoi().
      
      The errors have been seen "by chance" when manually looking at the
      results from LKFT.

      selftests: mptcp: depend on SYN_COOKIES · 6c8880fc
      Matthieu Baerts authored
      MPTCP selftests are using TCP SYN Cookies for quite a while now, since
      v5.9.
      
      Some CIs don't have this config option enabled and this is causing
      issues in the tests:
      
        # ns1 MPTCP -> ns1 (10.0.1.1:10000      ) MPTCP     (duration   167ms) sysctl: cannot stat /proc/sys/net/ipv4/tcp_syncookies: No such file or directory
        # [ OK ]./mptcp_connect.sh: line 554: [: -eq: unary operator expected
      
      There is no impact in the results but the test is not doing what it is
      supposed to do.
