When loading a device-mapper table for a request-based mapped device,
and the allocation/initialization of the blk_mq_tag_set for the device
fails, a following device remove will cause a double free.
E.g. (dmesg):
device-mapper: core: Cannot initialize queue for request-based dm-mq mapped device
device-mapper: ioctl: unable to set up device queue for new table.

Kernel panic - not syncing: Fatal exception: panic_on_oops
When allocation/initialization of the blk_mq_tag_set fails in
dm_mq_init_request_queue(), it is uninitialized/freed, but the pointer
is not reset to NULL; so when dev_remove() later gets into
dm_mq_cleanup_mapped_device() it sees the pointer and tries to
uninitialize and free it again.
Fix this by setting the pointer to NULL in dm_mq_init_request_queue()
error-handling. Also set it to NULL in dm_mq_cleanup_mapped_device().

It was reported that a fix to the ring buffer recursion detection would
cause a hung machine when performing suspend / resume testing. The
following backtrace was extracted from debugging that case:

? dpm_run_callback+0x49/0xc0
With the following RIP:
RIP: 0010:native_queued_spin_lock_slowpath+0x69/0x200
Since the fix to the recursion detection would allow a single recursion to
happen while tracing, this lead to the trace_clock_global() taking a spin
lock and then trying to take it again:
ring_buffer_lock_reserve() {
trace_clock_global() {
arch_spin_lock() {
queued_spin_lock_slowpath() {
/* lock taken */
(something else gets traced by function graph tracer)
ring_buffer_lock_reserve() {
trace_clock_global() {
arch_spin_lock() {
queued_spin_lock_slowpath() {
/* DEAD LOCK! */
Tracing should *never* block, as it can lead to strange lockups like the
above.
Restructure the trace_clock_global() code to instead of simply taking a
lock to update the recorded "prev_time" simply use it, as two events
happening on two different CPUs that calls this at the same time, really
doesn't matter which one goes first. Use a trylock to grab the lock for
updating the prev_time, and if it fails, simply try again the next time.
If it failed to be taken, that means something else is already updating
it.

Variable 'ret' is set to zero but this value is never read as it is
overwritten with a new value later on, hence it is a redundant assignment
and can be removed.

Query like 'file tcp_input.c line 1234 +p' was broken by
commit aaebe329bff0 ("dyndbg: accept 'file foo.c:func1' and 'file
foo.c:10-100'") because a file name without a ':' now makes the loop in
ddebug_parse_query() exits early before parsing the 'line 1234' part.
As a result, all pr_debug() in tcp_input.c will be enabled, instead of only
the one on line 1234. Changing 'break' to 'continue' fixes this.

drm/tegra: Changes for v5.13-rc1
The changes this time around contain a couple of fixes for host1x along
with some improvements for Tegra DRM. Most notably the Tegra DRM driver
now supports the hardware cursor on Tegra186 and later, more correctly
reflects the capabilities of the display pipelines on various Tegra SoC
generations and knows how to deal with the dGPU sector layout by using
framebuffer modifiers.

The RTC_OSC_REG register is 32-bit, but the useful information is found
in the 7 least significant bits (bits 7-31 are reserved). And in fact,
as you can see from the code, all read accesses are 8-bit, as well as
some writes. Let's make sure all writes are 8-bit. Moreover, in contexts
where consecutive reads / writes after the busy check must take place
within 15 us, it is better not to waste time on useless accesses.

Now that the core is aware of whether alarms are available, it is possible
to decide whether UIE emulation is required before actually trying to set
the alarm.
This greatly simplifies rtc_update_irq_enable because there is now only one
error value to track and is not relying on the return value of
__rtc_set_alarm anymore.

Pull networking updates from Jakub Kicinski:
"Core:
- bpf:
- allow bpf programs calling kernel functions (initially to
reuse TCP congestion control implementations)
- enable task local storage for tracing programs - remove the
need to store per-task state in hash maps, and allow tracing
programs access to task local storage previously added for
BPF_LSM
- add bpf_for_each_map_elem() helper, allowing programs to walk
all map elements in a more robust and easier to verify fashion
- sockmap: support UDP and cross-protocol BPF_SK_SKB_VERDICT
redirection
- lpm: add support for batched ops in LPM trie
- add BTF_KIND_FLOAT support - mostly to allow use of BTF on
s390 which has floats in its headers files
- improve BPF syscall documentation and extend the use of kdoc
parsing scripts we already employ for bpf-helpers
- libbpf, bpftool: support static linking of BPF ELF files
- improve support for encapsulation of L2 packets
- xdp: restructure redirect actions to avoid a runtime lookup,
improving performance by 4-8% in microbenchmarks
- xsk: build skb by page (aka generic zerocopy xmit) - improve
performance of software AF_XDP path by 33% for devices which don't
need headers in the linear skb part (e.g. virtio)
- nexthop: resilient next-hop groups - improve path stability on
next-hops group changes (incl. offload for mlxsw)
- ipv6: segment routing: add support for IPv4 decapsulation
- icmp: add support for RFC 8335 extended PROBE messages
- inet: use bigger hash table for IP ID generation
- tcp: deal better with delayed TX completions - make sure we don't
give up on fast TCP retransmissions only because driver is slow in
reporting that it completed transmitting the original
- tcp: reorder tcp_congestion_ops for better cache locality
- mptcp:
- add sockopt support for common TCP options
- add support for common TCP msg flags
- include multiple address ids in RM_ADDR
- add reset option support for resetting one subflow
- udp: GRO L4 improvements - improve 'forward' / 'frag_list'
co-existence with UDP tunnel GRO, allowing the first to take place
correctly even for encapsulated UDP traffic
- micro-optimize dev_gro_receive() and flow dissection, avoid
retpoline overhead on VLAN and TEB GRO

Pull xfs updates from Darrick Wong:
"The notable user-visible addition this cycle is ability to remove
space from the last AG in a filesystem. This is the first of many
changes needed for full-fledged support for shrinking a filesystem.
Still needed are (a) the ability to reorganize files and metadata away
from the end of the fs; (b) the ability to remove entire allocation
groups; (c) shrink support for realtime volumes; and (d) thorough
testing of (a-c).
There are a number of performance improvements in this code drop: Dave
streamlined various parts of the buffer logging code and reduced the
cost of various debugging checks, and added the ability to pre-create
the xattr structures while creating files. Brian eliminated
transaction reservations that were being held across writeback (thus
reducing livelock potential.
Other random pieces: Pavel fixed the repetitve warnings about
deprecated mount options, I fixed online fsck to behave itself when a
readonly remount comes in during scrub, and refactored various other
parts of that code, Christoph contributed a lot of refactoring this
cycle. The xfs_icdinode structure has been absorbed into the (incore)
xfs_inode structure, and the format and flags handling around
xfs_inode_fork structures has been simplified. Chandan provided a
number of fixes for extent count overflow related problems that have
been shaken out by debugging knobs added during 5.12.
Summary:
- Various minor fixes in online scrub.
- Prevent metadata files from being automatically inactivated.
- Validate btree heights by the computed per-btree limits.
- Don't warn about remounting with deprecated mount options.
- Initialize attr forks at create time if we suspect we're going to
need to store them.
- Reduce memory reallocation workouts in the logging code.
- Fix some theoretical math calculation errors in logged buffers that
span multiple discontig memory ranges but contiguous ondisk
regions.
- Speedups in dirty buffer bitmap handling.
- Make type verifier functions more inline-happy to reduce overhead.
- Reduce debug overhead in directory checking code.
- Many many typo fixes.
- Begin to handle the permanent loss of the very end of a filesystem.
- Fold struct xfs_icdinode into xfs_inode.
- Deprecate the long defunct BMV_IF_NO_DMAPI_READ from the bmapx
ioctl.
- Remove a broken directory block format check from online scrub.
- Fix a bug where we could produce an unnecessarily tall data fork
btree when creating an attr fork.
- Fix scrub and readonly remounts racing.
- Fix a writeback ioend log deadlock problem by dropping the behavior
where we could preallocate a setfilesize transaction.
- Fix some bugs in the new extent count checking code.
- Fix some bugs in the attr fork preallocation code.
- Refactor if_flags out of the incore inode fork data structure"

A failing usercopy of the slot uid will lead to a stale entry in the
file descriptor table as put_unused_fd() won't release it. This enables
userland to refer to a dangling 'file' object through that still valid
file descriptor, leading to all kinds of use-after-free exploitation
scenarios.
Exchanging put_unused_fd() for close_fd(), ksys_close() or alike won't
solve the underlying issue, as the file descriptor might have been
replaced in the meantime, e.g. via userland calling close() on it
(leading to a NULL pointer dereference in the error handling code as
'fget(enclave_fd)' will return a NULL pointer) or by dup2()'ing a
completely different file object to that very file descriptor, leading
to the same situation: a dangling file descriptor pointing to a freed
object -- just in this case to a file object of user's choosing.
Generally speaking, after the call to fd_install() the file descriptor
is live and userland is free to do whatever with it. We cannot rely on
it to still refer to our enclave object afterwards. In fact, by abusing
userfaultfd() userland can hit the condition without any racing and
abuse the error handling in the nitro code as it pleases.
To fix the above issues, defer the call to fd_install() until all
possible errors are handled. In this case it's just the usercopy, so do
it directly in ne_create_vm_ioctl() itself.
