IB/hfi1: Ensure pq is not left on waitlist
The following warning can occur when a pq is left on the dmawait list and
the pq is then freed:

The issue happens when wait_event_interruptible_timeout() returns a value
<= 0.
In that case, the pq is left on the list. The code continues sending
packets and potentially can complete the current request with the pq still
on the dmawait list provided no descriptor shortage is seen.
If the pq is torn down in that state, the sdma interrupt handler could
find the now freed pq on the list with list corruption or memory
corruption resulting.
Fix by adding a flush routine to ensure that the pq is never on a list
after processing a request.
A follow-up patch series will address issues with seqlock surfaced in:
https://lore.kernel.org/r/20200320003129.GP20941@ziepe.ca
The seqlock use for sdma will then be converted to a spin lock since the
list_empty() doesn't need the protection afforded by the sequence lock
currently in use.

IB/rdmavt: Free kernel completion queue when done
When a kernel ULP requests the rdmavt to create a completion queue, it
allocated the queue and set cq->kqueue to point to it. However, when the
completion queue is destroyed, cq->queue is freed instead, leading to a
memory leak:

RDMA/mad: Do not crash if the rdma device does not have a umad interface
Non-IB devices do not have a umad interface and the client_data will be
left set to NULL. In this case calling get_nl_info() will try to kref a
NULL cdev causing a crash:

RDMA/mlx5: Fix the number of hwcounters of a dynamic counter
When we read the global counter and there's any dynamic counter allocated,
the value of a hwcounter is the sum of the default counter and all dynamic
counters. So the number of hwcounters of a dynamically allocated counter
must be same as of the default counter, otherwise there will be read
violations.
This fixes the KASAN slab-out-of-bounds bug:

RDMA/odp: Fix leaking the tgid for implicit ODP
The tgid used to be part of ib_umem_free_notifier(), when it was reworked
it got moved to release, but it should have been unconditional as all umem
alloc paths get the tgid.
As is, creating an implicit ODP will leak the tgid reference.

ARM: SoC fixes
We've been accruing these for a couple of weeks, so the batch is a bit
bigger than usual.
Largest delta is due to a led-bl driver that is added -- there was
a miscommunication before the merge window and the driver didn't make it
in. Due to this, the platforms needing it regressed. At this point, it
seemed easier to add the new driver than unwind the changes.
Besides that, there are a handful of various fixes:
- AMD tee memory leak fix
- A handful of fixlets for i.MX SCU communication
- A few maintainers woke up and realized DEBUG_FS had been missing for
a while, so a few updates of that.
... and the usual collection of smaller fixes to various platforms.

io_uring: fix lockup with timeouts
There is a recipe to deadlock the kernel: submit a timeout sqe with a linked_timeout (e.g. test_single_link_timeout_ception() from liburing), and SIGKILL the process. Then, io_kill_timeouts() takes @ctx->completion_lock, but the timeout isn't flagged with REQ_F_COMP_LOCKED, and will try to double grab it during io_put_free() to cancel the linked timeout. Probably, the same can happen with another io_kill_timeout() call site, that is io_commit_cqring().

powerpc fixes for 5.6 #4
One fix for a recent regression to our breakpoint/watchpoint code.
Another fix for our KUAP support, this time a missing annotation in a rarely
used path in signal handling.
A fix for our handling of a CPU feature that effects the PMU, when booting
guests in some configurations.
A minor fix to our linker script to explicitly include the .BTF section.
Thanks to:
Christophe Leroy, Desnes A. Nunes do Rosario, Leonardo Bras, Naveen N. Rao,
Ravi Bangoria, Stefan Berger.

linux-kselftest-5.6-rc5
This Kselftest update for Linux 5.6-rc5 consists of a cleanup patch to undo changes to global .gitignore that added selftests/lkdtm objects and add them to a local selftests/lkdtm/.gitignore. Summary of Linus's comments on local vs. global gitignore scope: - Keep local gitignore patterns in local files. - Put only global gitignore patterns in the top-level gitignore file. Local scope keeps things much better separated. It also incidentally means that if a directory gets renamed, the gitignore file continues to work unless in the case of renaming the actual files themselves that are named in the gitignore. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEPZKym/RZuOCGeA/kCwJExA0NQxwFAl5izzwACgkQCwJExA0N QxxGpBAArJzDZp02xR8QfCrFyY8qXsFOEkFhjc22jNx6nl5cMb6nRUFbDszCEq05 0QmVb1Hfh+tsz5PXtcugC/pfulUPmho8mN6sXEfwjqcyQFj/4y94wfpRig/KqMXj ECV3zjm39wb3iAh5PQxrymzWrv0ZmmKphpi9fpUDGCGEoG7cemsfIfwkRKBUFBOa O1PTz0sLbhMQs02N/5mwJk0WGxtjFQ5ShM5EQh1nzxgA3ObXcjybMarusWhVx2SN oO3UR7hrJTTozgcisiK8xz8SP4Hq1i6E11HE06PfE52YsVAEwNjsXf0KushKxWHo sm9B4dtkcy1qM+JfbVRKS9LPSyKiGEDUzmqKQy2dgVUX2K3ScJ6scXNnLSnPbqjX OPjaMTkIYUyxZ4Z4vn8a9+b3xc6fLxi9aiaxqfpdfbIJyiIyGhAvVwS1zWa1AUqW /mEPRE9BplpQTthkBHNHCdwG1NGAzV/gwtZHDeuiy/BdtlQNjzqr0vh26sTN1z0M NPMAl2Teqv2NOfOcHvhphyNXuuW9IE96ZoYDyFz6ZF6jN+J9jZtWpHRCnnd7dK9Q fLwbJUZtfr7v0r/1jsYag0MPJlyBaW1rvuEH9rpbF+Z/+ODrDPiAt05bPmrk9BYO hwmvcWsCalQUlOYQdhpEUFJgHoWoy4GJMMI3ao+xCooXiAylTt0= =8sYZ -----END PGP SIGNATURE----- Merge tag 'linux-kselftest-5.6-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest Pull kselftest update from Shuah Khan: "This consists of a cleanup patch to undo changes to global .gitignore that added selftests/lkdtm objects and add them to a local selftests/lkdtm/.gitignore.

RISC-V Fixes for 5.6-rc5
This tag contains a handful of fixes that I would like to target for 5.6:
* A pair of fixes to module loading, which we hope solve the last of the issues
with module text being loaded too sparsely for our call relocations.
* A Kconfig fix that disallows selecting memory models not supported by NOMMU.
* A series of Kconfig updates to ease selecting the drivers necessary to run on
QEMU's virt platform.
* DTS updates for SiFive's HiFive Unleashed.
* A fix to our seccomp support that avoids mangling restartable syscalls.

}
When resize the screen, update the 'vc->vc_size_row' to the new_row_size,
but when 'set_origin' in 'vgacon_set_origin', vgacon use 'vga_vram_base'
for 'vc_origin' and 'vc_visible_origin', not 'vc_screenbuf'. It maybe
smaller than 'vc_screenbuf'. When TIOCLINUX, use the new_row_size to calc
the offset, it maybe larger than the vga_vram_size in vgacon driver, then
bad access.
Also, if set an larger screenbuf firstly, then set an more larger
screenbuf, when copy old_origin to new_origin, a bad access may happen.
So, If the screen size larger than vga_vram, resize screen should be
failed. This alse fix CVE-2020-8649 and CVE-2020-8647.
Linus pointed out that overflow checking seems absent. We're saved by
the existing bounds checks in vc_do_resize() with rather strict
limits:
if (cols > VC_RESIZE_MAXCOL || lines > VC_RESIZE_MAXROW)
return -EINVAL;

dt-bindings: arm: Fixup the DT bindings for hierarchical PSCI states
The hierarchical topology with power-domain should be described through
child nodes, rather than as currently described in the PSCI root node. Fix
this by adding a patternProperties with a corresponding reference to the
power-domain DT binding.
Additionally, update the example to conform to the new pattern, but also to
the adjusted domain-idle-state DT binding.

Jann suggested the approach of using a double rcu callback to achieve this. It's important that we do a nested call_rcu() callback, as otherwise the free could be ordered before the atomic switch, even if the latter was already queued.

locks: fix a potential use-after-free problem when wakeup a waiter
'16306a61d3b7 ("fs/locks: always delete_block after waiting.")' add the
logic to check waiter->fl_blocker without blocked_lock_lock. And it will
trigger a UAF when we try to wakeup some waiter：
Thread 1 has create a write flock a on file, and now thread 2 try to
unlock and delete flock a, thread 3 try to add flock b on the same file.
Thread2 Thread3
flock syscall(create flock b)
...flock_lock_inode_wait
flock_lock_inode(will insert
our fl_blocked_member list
to flock a's fl_blocked_requests)
sleep
flock syscall(unlock)
...flock_lock_inode_wait
locks_delete_lock_ctx
...__locks_wake_up_blocks
__locks_delete_blocks(
b->fl_blocker = NULL)
...
break by a signal
locks_delete_block
b->fl_blocker == NULL &&
list_empty(&b->fl_blocked_requests)
success, return directly
locks_free_lock b
wake_up(&b->fl_waiter)
trigger UAF
Fix it by remove this logic, and this patch may also fix CVE-2019-19769.

block, bfq: fix overwrite of bfq_group pointer in bfq_find_set_group()
The bfq_find_set_group() function takes as input a blkcg (which represents a cgroup) and retrieves the corresponding bfq_group, then it updates the bfq internal group hierarchy (see comments inside the function for why this is needed) and finally it returns the bfq_group. In the hierarchy update cycle, the pointer holding the correct bfq_group that has to be returned is mistakenly used to traverse the hierarchy bottom to top, meaning that in each iteration it gets overwritten with the parent of the current group. Since the update cycle stops at root's children (depth = 2), the overwrite becomes a problem only if the blkcg describes a cgroup at a hierarchy level deeper than that (depth > 2). In this case the root's child that happens to be also an ancestor of the correct bfq_group is returned. The main consequence is that processes contained in a cgroup at depth greater than 2 are wrongly placed in the group described above by BFQ. This commits fixes this problem by using a different bfq_group pointer in the update cycle in order to avoid the overwrite of the variable holding the original group reference.

arch/Kconfig: update HAVE_RELIABLE_STACKTRACE description
save_stack_trace_tsk_reliable() is not the only function providing the reliable stack traces anymore. Architecture might define ARCH_STACKWALK which provides a newer stack walking interface and has arch_stack_walk_reliable() function. Update the description accordingly.
