      mksysmap: Fix the mismatch of 'L0' symbols in System.map · c17a2538
      Youling Tang authored
      When System.map was generated, the kernel used mksysmap to filter the
      kernel symbols, we need to filter "L0" symbols in LoongArch architecture.
      
      $ cat System.map | grep L0
      9000000000221540 t L0
      
      The L0 symbol exists in System.map, but not in .tmp_System.map. When
      "cmp -s System.map .tmp_System.map" will show "Inconsistent kallsyms
      data" error message in link-vmlinux.sh script.

       "Here are some small driver core and debugfs fixes for 6.0-rc5.
      
        Included in here are:
      
         - multiple attempts to get the arch_topology code to work properly on
           non-cluster SMT systems. First attempt caused build breakages in
           linux-next and 0-day, second try worked.
      
         - debugfs fixes for a long-suffering memory leak. The pattern of
           debugfs_remove(debugfs_lookup(...)) turns out to leak dentries, so
           add debugfs_lookup_and_remove() to fix this problem. Also fix up
           the scheduler debug code that highlighted this problem. Fixes for
           other subsystems will be trickling in over the next few months for
           this same issue once the debugfs function is merged.
      
        All of these have been in linux-next since Wednesday with no reported
        problems"

      Replace autoloading data based on the ACPI EC device with the DMI

      that the EC device does not work properly.

      io_uring/rw: fix short rw error handling · 4d9cb92c
      Pavel Begunkov authored
      We have a couple of problems, first reports of unexpected link breakage
      for reads when cqe->res indicates that the IO was done in full. The
      reason here is partial IO with retries.
      
      TL;DR; we compare the result in __io_complete_rw_common() against
      req->cqe.res, but req->cqe.res doesn't store the full length but rather
      the length left to be done. So, when we pass the full corrected result
      via kiocb_done() -> __io_complete_rw_common(), it fails.
      
      The second problem is that we don't try to correct res in
      io_complete_rw(), which, for instance, might be a problem for O_DIRECT
      but when a prefix of data was cached in the page cache. We also
      definitely don't want to pass a corrected result into io_rw_done().
      
      The fix here is to leave __io_complete_rw_common() alone, always pass
      not corrected result into it and fix it up as the last step just before
      actually finishing the I/O.

      NFSD: fix regression with setting ACLs. · 00801cd9
      NeilBrown authored
      A recent patch moved ACL setting into nfsd_setattr().
      Unfortunately it didn't work as nfsd_setattr() aborts early if
      iap->ia_valid is 0.
      
      Remove this test, and instead avoid calling notify_change() when
      ia_valid is 0.
      
      This means that nfsd_setattr() will now *always* lock the inode.
      Previously it didn't if only a ATTR_MODE change was requested on a
      symlink (see Commit 15b7a1b8 ("[PATCH] knfsd: fix setattr-on-symlink
      error return")). I don't think this change really matters.

      tracefs: Only clobber mode/uid/gid on remount if asked · 47311db8
      Brian Norris authored
      Users may have explicitly configured their tracefs permissions; we
      shouldn't overwrite those just because a second mount appeared.
      
      Only clobber if the options were provided at mount time.
      
      Note: the previous behavior was especially surprising in the presence of
      automounted /sys/kernel/debug/tracing/.
      
      Existing behavior:
      
        ## Pre-existing status: tracefs is 0755.
        # stat -c '%A' /sys/kernel/tracing/
        drwxr-xr-x
      
        ## (Re)trigger the automount.
        # umount /sys/kernel/debug/tracing
        # stat -c '%A' /sys/kernel/debug/tracing/.
        drwx------
      
        ## Unexpected: the automount changed mode for other mount instances.
        # stat -c '%A' /sys/kernel/tracing/
        drwx------
      
      New behavior (after this change):
      
        ## Pre-existing status: tracefs is 0755.
        # stat -c '%A' /sys/kernel/tracing/
        drwxr-xr-x
      
        ## (Re)trigger the automount.
        # umount /sys/kernel/debug/tracing
        # stat -c '%A' /sys/kernel/debug/tracing/.
        drwxr-xr-x
      
        ## Expected: the automount does not change other mount instances.

      kprobes: Prohibit probes in gate area · 1efda38d
      Christian A. Ehrhardt authored
      The system call gate area counts as kernel text but trying
      to install a kprobe in this area fails with an Oops later on.
      To fix this explicitly disallow the gate area for kprobes.

      SBI firmware should report total number of firmware and hardware counters
      including unused ones or special ones. In this case the kernel doesn't need
      to make any assumptions about gaps in reported counters, e.g. excluded timer
      counter. That was fixed in OpenSBI v1.1 by commit 3f66465fb6bf ("lib: pmu:
      allow to use the highest available counter"). This kernel patch has no effect
      if SBI firmware behaves correctly. However it eliminates access beyond the
      allocated pmu_ctr_list if the kernel is used with OpenSBI older than v1.1.
