      cifs: reinstate original behavior again for forceuid/forcegid · 77d8aa79
      Takayuki Nagata authored
      forceuid/forcegid should be enabled by default when uid=/gid= options are
      specified, but commit 24e0a1ef ("cifs: switch to new mount api")
      changed the behavior. Due to the change, a mounted share does not show
      intentional uid/gid for files and directories even though uid=/gid=
      options are specified since forceuid/forcegid are not enabled.
      
      This patch reinstates original behavior that overrides uid/gid with
      specified uid/gid by the options.

      Kent Overstreet authored
      discard_new_inode() is the wrong interface to use when we need to free
      an inode that was never inserted into the inode hash table; we can
      bypass the whole iput() -> evict() path and replace it with
      __destroy_inode(); kmem_cache_free() - this fixes a WARN_ON() about
      I_NEW.

      bcachefs: Fix deadlock in journal write path · 85ab365f
      Kent Overstreet authored
      bch2_journal_write() was incorrectly waiting on earlier journal writes
      synchronously; this usually worked because most of the time we'd be
      running in the context of a thread that did a journal_buf_put(), but
      sometimes we'd be running out of the same workqueue that completes those
      prior journal writes.
      
      Additionally, this makes sure to punt to a workqueue before submitting
      preflushes - we really don't want to be calling submit_bio() in the main
      transaction commit path.

      bcachefs: Tweak btree key cache shrinker so it actually frees · adfe9357
      Kent Overstreet authored
      Freeing key cache items is a multi stage process; we need to wait for an
      SRCU grace period to elapse, and we handle this ourselves - partially to
      avoid callback overhead, but primarily so that when allocating we can
      first allocate from the freed items waiting for an SRCU grace period.
      
      Previously, the shrinker was counting the items on the 'waiting for SRCU
      grace period' lists as items being scanned, but this meant that too many
      items waiting for an SRCU grace period could prevent it from doing any
      work at all.
      
      After this, we're seeing that items skipped due to the accessed bit are
      the main cause of the shrinker not making any progress, and we actually
      want the key cache shrinker to run quite aggressively because reclaimed
      items will still generally be found (more compactly) in the btree node
      cache - so we also tweak the shrinker to not count those against
      nr_to_scan.

       "This is a bit on the large side, mostly due to two changes:
      
         - Changes to disable some broken PMU virtualization (see below for
           details under "x86 PMU")
      
         - Clean up SVM's enter/exit assembly code so that it can be compiled
           without OBJECT_FILES_NON_STANDARD. This fixes a warning "Unpatched
           return thunk in use. This should not happen!" when running KVM
           selftests.
      
        Everything else is small bugfixes and selftest changes:
      
         - Fix a mostly benign bug in the gfn_to_pfn_cache infrastructure
           where KVM would allow userspace to refresh the cache with a bogus
           GPA. The bug has existed for quite some time, but was exposed by a
           new sanity check added in 6.9 (to ensure a cache is either
           GPA-based or HVA-based).
      
         - Drop an unused param from gfn_to_pfn_cache_invalidate_start() that
           got left behind during a 6.9 cleanup.
      
         - Fix a math goof in x86's hugepage logic for
           KVM_SET_MEMORY_ATTRIBUTES that results in an array overflow
           (detected by KASAN).
      
         - Fix a bug where KVM incorrectly clears root_role.direct when
           userspace sets guest CPUID.
      
         - Fix a dirty logging bug in the where KVM fails to write-protect
           SPTEs used by a nested guest, if KVM is using Page-Modification
           Logging and the nested hypervisor is NOT using EPT.
      
        x86 PMU:
      
         - Drop support for virtualizing adaptive PEBS, as KVM's
           implementation is architecturally broken without an obvious/easy
           path forward, and because exposing adaptive PEBS can leak host LBRs
           to the guest, i.e. can leak host kernel addresses to the guest.
      
         - Set the enable bits for general purpose counters in
           PERF_GLOBAL_CTRL at RESET time, as done by both Intel and AMD
           processors.
      
         - Disable LBR virtualization on CPUs that don't support LBR
           callstacks, as KVM unconditionally uses
           PERF_SAMPLE_BRANCH_CALL_STACK when creating the perf event, and
           would fail on such CPUs.
      
        Tests:
      
         - Fix a flaw in the max_guest_memory selftest that results in it
           exhausting the supply of ucall structures when run with more than
           256 vCPUs.

      Pull clk fixes from Stephen Boyd:
       "A couple clk driver fixes, a build fix, and a deadlock fix:
      
         - Mediatek mt7988 has broken PCIe because the wrong parent is used
      
         - Mediatek clk drivers may deadlock when registering their clks
           because the clk provider device is repeatedly runtime PM resumed
           and suspended during probe and clk registration.
      
           Resuming the clk provider device deadlocks with an ABBA deadlock
           due to genpd_lock and the clk prepare_lock. The fix is to keep the
           device runtime resumed while registering clks.
      
         - Another runtime PM related deadlock, this time with disabling
           unused clks during late init.
      
           We get an ABBA deadlock where a device is runtime PM resuming (or
           suspending) while the disabling of unused clks is happening in
           parallel. That runtime PM action calls into the clk framework and
           tries to grab the clk prepare_lock while the disabling of unused
           clks holds the prepare_lock and is waiting for that runtime PM
           action to complete.
      
           The fix is to runtime resume all the clk provider devices before
           grabbing the clk prepare_lock during disable unused.

      Performance regression reported with NFS/RDMA using Omnipath,
      bisected to commit e084ee67 ("svcrdma: Add Write chunk WRs to
      the RPC's Send WR chain").
      
      Tracing on the server reports:
      
        nfsd-7771  [060]  1758.891809: svcrdma_sq_post_err:
      	cq.id=205 cid=226 sc_sq_avail=13643/851 status=-12
      
      sq_post_err reports ENOMEM, and the rdma->sc_sq_avail (13643) is
      larger than rdma->sc_sq_depth (851). The number of available Send
      Queue entries is always supposed to be smaller than the Send Queue
      depth. That seems like a Send Queue accounting bug in svcrdma.
      
      As it's getting to be late in the 6.9-rc cycle, revert this commit.
      It can be revisited in a subsequent kernel release.

      smb: client: fix rename(2) regression against samba · 18d86965
      Paulo Alcantara authored
      After commit 2c7d399e ("smb: client: reuse file lease key in
      compound operations") the client started reusing lease keys for
      rename, unlink and set path size operations to prevent it from
      breaking its own leases and thus causing unnecessary lease breaks to
      same connection.
      
      The implementation relies on positive dentries and
      cifsInodeInfo::lease_granted to decide whether reusing lease keys for
      the compound requests.  cifsInodeInfo::lease_granted was introduced by
      commit 0ab95c25 ("Defer close only when lease is enabled.") to
      indicate whether lease caching is granted for a specific file, but
      that can only happen until file is open, so
      cifsInodeInfo::lease_granted was left uninitialised in ->alloc_inode
      and then client started sending random lease keys for files that
      hadn't any leases.
      
      This fixes the following test case against samba:
      
      mount.cifs //srv/share /mnt/1 -o ...,nosharesock
      mount.cifs //srv/share /mnt/2 -o ...,nosharesock
      touch /mnt/1/foo; tail -f /mnt/1/foo & pid=$!
      mv /mnt/2/foo /mnt/2/bar # fails with -EIO
      kill $pid

      cifs: Fix reacquisition of volume cookie on still-live connection · dad80c6b
      David Howells authored
      During mount, cifs_mount_get_tcon() gets a tcon resource connection record
      and then attaches an fscache volume cookie to it.  However, it does this
      irrespective of whether or not the tcon returned from cifs_get_tcon() is a
      new record or one that's already in use.  This leads to a warning about a
      volume cookie collision and a leaked volume cookie because tcon->fscache
      gets reset.
      
      Fix this be adding a mutex and a "we've already tried this" flag and only
      doing it once for the lifetime of the tcon.
      
      [!] Note: Looking at cifs_mount_get_tcon(), a more general solution may
      actually be required.  Reacquiring the volume cookie isn't the only thing
      that function does: it also partially reinitialises the tcon record without
      any locking - which may cause live filesystem ops already using the tcon
      through a previous mount to malfunction.
      
      This can be reproduced simply by something like:
      
          mount //example.com/test /xfstest.test -o user=shares,pass=xxx,fsc
          mount //example.com/test /mnt -o user=shares,pass=xxx,fsc
