75e68e5bf2 bpf, sockhash: Synchronize delete from bucket list on map free
We can end up modifying the sockhash bucket list from two CPUs when a
sockhash is being destroyed (sock_hash_free) on one CPU, while a socket
that is in the sockhash is unlinking itself from it on another CPU
it (sock_hash_delete_from_link).

This results in accessing a list element that is in an undefined state as
reported by KASAN:

Fix it by reintroducing spin-lock protected critical section around the
code that removes the elements from the bucket on sockhash free.

To do that we also need to defer processing of removed elements, until out
of atomic context so that we can unlink the socket from the map when
holding the sock lock.

33a7c83156 bpf, sockhash: Fix memory leak when unlinking sockets in sock_hash_free
When sockhash gets destroyed while sockets are still linked to it, we will
walk the bucket lists and delete the links. However, we are not freeing the
list elements after processing them, leaking the memory.

The leak can be triggered by close()'ing a sockhash map when it still
contains sockets, and observed with kmemleak:

  unreferenced object 0xffff888116e86f00 (size 64):

487082fb7b bpf/sockmap: Fix kernel panic at __tcp_bpf_recvmsg
When user application calls read() with MSG_PEEK flag to read data
of bpf sockmap socket, kernel panic happens at
__tcp_bpf_recvmsg+0x12c/0x350. sk_msg is not removed from ingress_msg
queue after read out under MSG_PEEK flag is set. Because it's not
judged whether sk_msg is the last msg of ingress_msg queue, the next
sk_msg may be the head of ingress_msg queue, whose memory address of
sg page is invalid. So it's necessary to add check codes to prevent
this problem.

1f2436229b selftests/bpf: Fix ringbuf selftest sample counting undeterminism
Fix test race, in which background poll can get either 5 or 6 samples,
depending on timing of notification. Prevent this by open-coding sample
triggering and forcing notification for the very last sample only.

Also switch to using atomic increments and exchanges for more obviously
reliable counting and checking. Additionally, check expected processed sample
counters for single-threaded use cases as well.

49b2357594 bpf: Fix unused-var without NETDEVICES
A recent commit added new variables only used if CONFIG_NETDEVICES is
set. A simple fix would be to only declare these variables if the same
condition is valid but Alexei suggested an even simpler solution:

    since CONFIG_NETDEVICES doesn't change anything in .h I think the
    best is to remove #ifdef CONFIG_NETDEVICES from net/core/filter.c
    and rely on sock_bindtoindex() returning ENOPROTOOPT in the extreme
    case of oddly configured kernels.

f1e455352b kgdb patches for 5.8-rc1
By far the biggest change in this cycle are the changes that allow much
 earlier debug of systems that are hooked up via UART by taking advantage
 of the earlycon framework to implement the kgdb I/O hooks before handing
 over to the regular polling I/O drivers once they are available. When
 discussing Doug's work we also found and fixed an broken
 raw_smp_processor_id() sequence in in_dbg_master().
 
 Also included are a collection of much smaller fixes and tweaks: a
 couple of tweaks to ged rid of doc gen or coccicheck warnings, future
 proof some internal calculations that made implicit power-of-2
 assumptions and eliminate some rather weird handling of magic
 environment variables in kdb.

 "By far the biggest change in this cycle are the changes that allow
  much earlier debug of systems that are hooked up via UART by taking
  advantage of the earlycon framework to implement the kgdb I/O hooks
  before handing over to the regular polling I/O drivers once they are
  available. When discussing Doug's work we also found and fixed an
  broken raw_smp_processor_id() sequence in in_dbg_master().

  Also included are a collection of much smaller fixes and tweaks: a
  couple of tweaks to ged rid of doc gen or coccicheck warnings, future
  proof some internal calculations that made implicit power-of-2
  assumptions and eliminate some rather weird handling of magic
  environment variables in kdb"

Merge tag 'threads-v5.8' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux

Pull thread updates from Christian Brauner:
 "We have been discussing using pidfds to attach to namespaces for quite
  a while and the patches have in one form or another already existed
  for about a year. But I wanted to wait to see how the general api
  would be received and adopted.

  This contains the changes to make it possible to use pidfds to attach
  to the namespaces of a process, i.e. they can be passed as the first
  argument to the setns() syscall.

  When only a single namespace type is specified the semantics are
  equivalent to passing an nsfd. That means setns(nsfd, CLONE_NEWNET)
  equals setns(pidfd, CLONE_NEWNET).

  However, when a pidfd is passed, multiple namespace flags can be
  specified in the second setns() argument and setns() will attach the
  caller to all the specified namespaces all at once or to none of them.

  Specifying 0 is not valid together with a pidfd. Here are just two
  obvious examples:

    setns(pidfd, CLONE_NEWPID | CLONE_NEWNS | CLONE_NEWNET);
    setns(pidfd, CLONE_NEWUSER);

  Allowing to also attach subsets of namespaces supports various
  use-cases where callers setns to a subset of namespaces to retain
  privilege, perform an action and then re-attach another subset of
  namespaces.

  Apart from significantly reducing the number of syscalls needed to
  attach to all currently supported namespaces (eight "open+setns"
  sequences vs just a single "setns()"), this also allows atomic setns
  to a set of namespaces, i.e. either attaching to all namespaces
  succeeds or we fail without having changed anything.

  This is centered around a new internal struct nsset which holds all
  information necessary for a task to switch to a new set of namespaces
  atomically. Fwiw, with this change a pidfd becomes the only token
  needed to interact with a container. I'm expecting this to be
  picked-up by util-linux for nsenter rather soon.

  Associated with this change is a shiny new test-suite dedicated to
  setns() (for pidfds and nsfds alike)"

Pull btrfs updates from David Sterba:
 "Highlights:

   - speedup dead root detection during orphan cleanup, eg. when there
     are many deleted subvolumes waiting to be cleaned, the trees are
     now looked up in radix tree instead of a O(N^2) search

   - snapshot creation with inherited qgroup will mark the qgroup
     inconsistent, requires a rescan

   - send will emit file capabilities after chown, this produces a
     stream that does not need postprocessing to set the capabilities
     again

   - direct io ported to iomap infrastructure, cleaned up and simplified
     code, notably removing last use of struct buffer_head in btrfs code

  Core changes:

   - factor out backreference iteration, to be used by ordinary
     backreferences and relocation code

   - improved global block reserve utilization
      * better logic to serialize requests
      * increased maximum available for unlink
      * improved handling on large pages (64K)

   - direct io cleanups and fixes
      * simplify layering, where cloned bios were unnecessarily created
        for some cases
      * error handling fixes (submit, endio)
      * remove repair worker thread, used to avoid deadlocks during
        repair

   - refactored block group reading code, preparatory work for new type
     of block group storage that should improve mount time on large
     filesystems

  Cleanups:

   - cleaned up (and slightly sped up) set/get helpers for metadata data
     structure members

   - root bit REF_COWS got renamed to SHAREABLE to reflect the that the
     blocks of the tree get shared either among subvolumes or with the
     relocation trees

  Fixes:

   - when subvolume deletion fails due to ENOSPC, the filesystem is not
     turned read-only

   - device scan deals with devices from other filesystems that changed
     ownership due to overwrite (mkfs)

   - fix a race between scrub and block group removal/allocation

   - fix long standing bug of a runaway balance operation, printing the
     same line to the syslog, caused by a stale status bit on a reloc
     tree that prevented progress

   - fix corrupt log due to concurrent fsync of inodes with shared
     extents

   - fix space underflow for NODATACOW and buffered writes when it for
     some reason needs to fallback to COW mode"

Pull DAX updates part two from Darrick Wong:
 "This time around, we're hoisting the DONTCACHE flag from XFS into the
  VFS so that we can make the incore DAX mode changes become effective
  sooner.

  We can't change the file data access mode on a live inode because we
  don't have a safe way to change the file ops pointers. The incore
  state change becomes effective at inode loading time, which can happen
  if the inode is evicted. Therefore, we're making it so that
  filesystems can ask the VFS to evict the inode as soon as the last
  holder drops.

  The per-fs changes to make this call this will be in subsequent pull
  requests from Ted and myself.

  Summary:

   - Introduce DONTCACHE flags for dentries and inodes. This hint will

Pull DAX updates part one from Darrick Wong:
 "After many years of LKML-wrangling about how to enable programs to
  query and influence the file data access mode (DAX) when a filesystem
  resides on storage devices such as persistent memory, Ira Weiny has
  emerged with a proposed set of standard behaviors that has not been
  shot down by anyone! We're more or less standardizing on the current
  XFS behavior and adapting ext4 to do the same.

  This is the first of a handful pull requests that will make ext4 and
  XFS present a consistent interface for user programs that care about
  DAX. We add a statx attribute that programs can check to see if DAX is
  enabled on a particular file. Then, we update the DAX documentation to
  spell out the user-visible behaviors that filesystems will guarantee
  (until the next storage industry shakeup). The on-disk inode flag has
  been in XFS for a few years now.

  Summary:

   - Clean up io_is_direct.

   - Add a new statx flag to indicate when file data access is being
     done via DAX (as opposed to the page cache).

   - Update the documentation for how system administrators and
     application programmers can take advantage of the (still
     experimental DAX) feature"

16d91548d1 New code for 5.8:
- Various cleanups to remove dead code, unnecessary conditionals,
       asserts, etc.
     - Fix a linker warning caused by xfs stuffing '-g' into CFLAGS
       redundantly.
     - Tighten up our dmesg logging to ensure that everything is prefixed
       with 'XFS' for easier grepping.
     - Kill a bunch of typedefs.
     - Refactor the deferred ops code to reduce indirect function calls.
     - Increase type-safety with the deferred ops code.
     - Make the DAX mount options a tri-state.
     - Fix some error handling problems in the inode flush code and clean up
       other inode flush warts.
     - Refactor log recovery so that each log item recovery functions now live
       with the other log item processing code.
     - Fix some SPDX forms.
     - Fix quota counter corruption if the fs crashes after running
       quotacheck but before any dquots get logged.
     - Don't fail metadata verification on zero-entry attr leaf blocks, since
       they're just part of the disk format now due to a historic lack of log
       atomicity.
     - Don't allow SWAPEXT between files with different [ugp]id when quotas
       are enabled.
     - Refactor inode fork reading and verification to run directly from the
       inode-from-disk function.  This means that we now actually guarantee
       that _iget'ted inodes are totally verified and ready to go.
     - Move the incore inode fork format and extent counts to the ifork
       structure.
     - Scalability improvements by reducing cacheline pingponging in
       struct xfs_mount.
     - More scalability improvements by removing m_active_trans from the
       hot path.
     - Fix inode counter update sanity checking to run /only/ on debug
       kernels.
     - Fix longstanding inconsistency in what error code we return when a
       program hits project quota limits (ENOSPC).
     - Fix group quota returning the wrong error code when a program hits
       group quota limits.
     - Fix per-type quota limits and grace periods for group and project
       quotas so that they actually work.
     - Allow extension of individual grace periods.
     - Refactor the non-reclaim inode radix tree walking code to remove a
       bunch of stupid little functions and straighten out the
       inconsistent naming schemes.
     - Fix a bug in speculative preallocation where we measured a new
       allocation based on the last extent mapping in the file instead of
       looking farther for the last contiguous space allocation.
     - Force delalloc writes to unwritten extents.  This closes a
       stale disk contents exposure vector if the system goes down before
       the write completes.

 "Most of the changes this cycle are refactoring of existing code in
  preparation for things landing in the future.

  We also fixed various problems and deficiencies in the quota
  implementation, and (I hope) the last of the stale read vectors by
  forcing write allocations to go through the unwritten state until the
  write completes.

  Summary:

   - Various cleanups to remove dead code, unnecessary conditionals,
     asserts, etc.

   - Fix a linker warning caused by xfs stuffing '-g' into CFLAGS
     redundantly.

   - Tighten up our dmesg logging to ensure that everything is prefixed
     with 'XFS' for easier grepping.

   - Kill a bunch of typedefs.

   - Refactor the deferred ops code to reduce indirect function calls.

   - Increase type-safety with the deferred ops code.

   - Make the DAX mount options a tri-state.

   - Fix some error handling problems in the inode flush code and clean
     up other inode flush warts.

   - Refactor log recovery so that each log item recovery functions now
     live with the other log item processing code.

   - Fix some SPDX forms.

   - Fix quota counter corruption if the fs crashes after running
     quotacheck but before any dquots get logged.

   - Don't fail metadata verification on zero-entry attr leaf blocks,
     since they're just part of the disk format now due to a historic
     lack of log atomicity.

   - Don't allow SWAPEXT between files with different [ugp]id when
     quotas are enabled.

   - Refactor inode fork reading and verification to run directly from
     the inode-from-disk function. This means that we now actually
     guarantee that _iget'ted inodes are totally verified and ready to
     go.

   - Move the incore inode fork format and extent counts to the ifork
     structure.

   - Scalability improvements by reducing cacheline pingponging in
     struct xfs_mount.

   - More scalability improvements by removing m_active_trans from the
     hot path.

   - Fix inode counter update sanity checking to run /only/ on debug
     kernels.

   - Fix longstanding inconsistency in what error code we return when a
     program hits project quota limits (ENOSPC).

   - Fix group quota returning the wrong error code when a program hits
     group quota limits.

   - Fix per-type quota limits and grace periods for group and project
     quotas so that they actually work.

   - Allow extension of individual grace periods.

   - Refactor the non-reclaim inode radix tree walking code to remove a
     bunch of stupid little functions and straighten out the
     inconsistent naming schemes.

   - Fix a bug in speculative preallocation where we measured a new
     allocation based on the last extent mapping in the file instead of
     looking farther for the last contiguous space allocation.

   - Force delalloc writes to unwritten extents. This closes a stale
     disk contents exposure vector if the system goes down before the
     write completes.

   - More lockdep whackamole"

Pull SELinux updates from Paul Moore:
 "The highlights:

   - A number of improvements to various SELinux internal data
     structures to help improve performance. We move the role
     transitions into a hash table. In the content structure we shift
     from hashing the content string (aka SELinux label) to the
     structure itself, when it is valid. This last change not only
     offers a speedup, but it helps us simplify the code some as well.

   - Add a new SELinux policy version which allows for a more space
     efficient way of storing the filename transitions in the binary
     policy. Given the default Fedora SELinux policy with the unconfined
     module enabled, this change drops the policy size from ~7.6MB to
     ~3.3MB. The kernel policy load time dropped as well.

   - Some fixes to the error handling code in the policy parser to
     properly return error codes when things go wrong"

When running with conntrack rules, the dropped overlap fragments may cause
EPERM to be returned to sendto. Instead of completely failing, just ignore
those errors and continue. If this causes packets with overlap fragments to
be dropped as expected, that is okay. And if it causes packets that are
expected to be received to be dropped, which should not happen, it will be
detected as failure.

1966391fa5 mm/migrate.c: attach_page_private already does the get_page
Just finished bisecting mmotm, to find why a test which used to take
four minutes now took more than an hour: the __buffer_migrate_page()
cleanup left behind a get_page() which attach_page_private() now does.

Fixes: cd0f371544 ("mm/migrate.c: call detach_page_private to cleanup code")

049fa17f7a Revert "tipc: Fix potential tipc_node refcnt leak in tipc_rcv"
This reverts commit de05842076.

There is no actual tipc_node refcnt leak as stated in the above commit.
The refcnt is hold carefully for the case of an asynchronous decryption
(i.e. -EINPROGRESS/-EBUSY and skb = NULL is returned), so that the node
object cannot be freed in the meantime. The counter will be re-balanced
when the operation's callback arrives with the decrypted buffer if any.
In other cases, e.g. a synchronous crypto the counter will be decreased
immediately when it is done.

Now with that commit, a kernel panic will occur when there is no node
found (i.e. n = NULL) in the 'tipc_rcv()' or a premature release of the
node object.

This commit solves the issues by reverting the said commit, but keeping
one valid case that the 'skb_linearize()' is failed.
