For libceph, this ensures that libceph instance sharing (share option)
continues to work. For rbd, this avoids blocklisting alive lock owners
(locker addr is always LEGACY, while watcher addr is ANY in nautilus).

In preparation for msgr2, make the cluster send us maps with addrvecs
including both LEGACY and MSGR2 addrs instead of a single LEGACY addr.
This means advertising support for SERVER_NAUTILUS and also some older
features: SERVER_MIMIC, MONENC and MONNAMES.
MONNAMES and MONENC are actually pre-argonaut, we just never updated
ceph_monmap_decode() for them. Decoding is unconditional, see commit
23c625ce3065 ("libceph: assume argonaut on the server side").
SERVER_MIMIC doesn't bear any meaning for the kernel client.
Since ceph_decode_entity_addrvec() is guarded by encoding version
checks (and in msgr2 case it is guarded implicitly by the fact that
server is speaking msgr2), we assume MSG_ADDR2 for it.

In msgr2, initial authentication happens with an exchange of msgr2
control frames -- MAuth message and struct ceph_mon_request_header
aren't used. Make that optional.
Stop reporting cephx protocol as "x". Use "cephx" instead.

- request service tickets together with auth ticket. Currently we get
auth ticket via CEPHX_GET_AUTH_SESSION_KEY op and then request service
tickets via CEPHX_GET_PRINCIPAL_SESSION_KEY op in a separate message.
Since nautilus, desired service tickets are shared togther with auth
ticket in CEPHX_GET_AUTH_SESSION_KEY reply.
- propagate session key and connection secret, if any. In preparation
for msgr2, update handle_reply() and verify_authorizer_reply() auth
ops to propagate session key and connection secret. Since nautilus,
if secure mode is negotiated, connection secret is shared either in
CEPHX_GET_AUTH_SESSION_KEY reply (for mons) or in a final authorizer
reply (for osds and mdses).

A pure move, no other changes.
Note that ceph_tcp_recv{msg,page}() and ceph_tcp_send{msg,page}()
helpers are also moved. msgr2 will bring its own, more efficient,
variants based on iov_iter. Switching msgr1 to them was considered
but decided against to avoid subtle regressions.

In preparation for msgr2, define internal messenger <-> protocol
interface (as opposed to external messenger <-> client interface, which
is struct ceph_connection_operations) consisting of try_read(),
try_write(), revoke(), revoke_incoming(), opened(), reset_session() and
reset_protocol() ops. The semantics are exactly the same as they are

In preparation for msgr2, rename msgr1 specific states and move the
defines to the header file.
Also drop state transition comments. They don't cover all possible
transitions (e.g. NEGOTIATING -> STANDBY, etc) and currently do more
harm than good.

The current setting allows the backoff to climb up to 5 minutes. This
is too high -- it becomes hard to tell whether the client is stuck on
something or just in backoff.
In userspace, ms_max_backoff is defaulted to 15 seconds. Let's do the
same.

When we added the btime feature in mainline ceph, we had to extend
struct ceph_mds_request_args so that it could be set. Implement the same
in the kernel client.
Rename ceph_mds_request_head with a _old extension, and a union
ceph_mds_request_args_ext to allow for the extended size of the new
header format.
Add the appropriate code to handle both formats in struct
create_request_message and key the behavior on whether the peer supports
CEPH_FEATURE_FS_BTIME.
The gid_list field in the payload is now populated from the saved
credential. For now, we don't add any support for setting the btime via
setattr, but this does enable us to add that in the future.

When setting the file/dir layout, it may need data pool info. So
in mds server, it needs to check the osdmap. At present, if mds
doesn't find the data pool specified, it will try to get the latest
osdmap. Now if pass the osd epoch for setxattr, the mds server can
only check this epoch of osdmap.

When recovering a session (a'la recover_session=clean), we want to do
all of the operations that we do on a forced umount, but changing the
mount state to SHUTDOWN is can cause queued MDS requests to fail when
the session comes back. Most of those can idle until the session is
recovered in this situation.
Reserve SHUTDOWN state for forced umount, and make a new RECOVER state
for the forced reconnect situation. Change several tests for equality with
SHUTDOWN to test for that or RECOVER.

Pull x86 SGC support from Borislav Petkov:
"Intel Software Guard eXtensions enablement. This has been long in the
making, we were one revision number short of 42. :)
Intel SGX is new hardware functionality that can be used by
applications to populate protected regions of user code and data
called enclaves. Once activated, the new hardware protects enclave
code and data from outside access and modification.
Enclaves provide a place to store secrets and process data with those
secrets. SGX has been used, for example, to decrypt video without
exposing the decryption keys to nosy debuggers that might be used to
subvert DRM. Software has generally been rewritten specifically to run
in enclaves, but there are also projects that try to run limited
unmodified software in enclaves.
Most of the functionality is concentrated into arch/x86/kernel/cpu/sgx/
except the addition of a new mprotect() hook to control enclave page
permissions and support for vDSO exceptions fixup which will is used
by SGX enclaves.

EFI capsule loading is a feature that was introduced into EFI long after
its initial introduction on Itanium, and it is highly unlikely that IA64
systems are receiving firmware updates in the first place, let alone
using EFI capsules.
So let's disable capsule support altogether on IA64. This fixes a build
error on IA64 due to a recent change that added an unconditional
include of asm/efi.h, which IA64 does not provide.
While at it, tweak the make rules a bit so that the EFI capsule
component that is always builtin (even if the EFI capsule loader itself
is built as a module) is omitted for all architectures if the module is
not enabled in the build.

ASoC: Updates for v5.11
There's a lot of changes here but mostly cleanups and driver specific
things, the most user visible change is the support for boot time
selection of Intel DSP firmware which will make it easier for people to
move over to the preferred modern implementations in distros and other
large scale deployments.
This also includes a merge of the new auxillary bus which was done in
anticipation of use by the Intel DSP drivers which didn't quite make it.
- Lots more cleanups and simplifications from Morimoto-san.
- Support for some basic DPCM systems in the audio graph card from
Sameer Pujar.
- Remove some old pre-DT Freescale drivers for platforms that are now
DT only.
- Move selection of which Intel DSP implementation to use to boot time
rather than requiring it to be selected at build time.
- Support for Allwinner H6 I2S, Analog Devices ADAU1372, Intel
Alderlake-S, GMediatek MT8192, NXP i.MX HDMI and XCVR, Realtek RT715,
Qualcomm SM8250 and simple GPIO based muxes.

cap_convert_nscap() does permission checking as well as conversion of the
xattr value conditionally based on fs's user-ns.
This is needed by overlayfs and probably other layered fs (ecryptfs) and is
what vfs_foo() is supposed to do anyway.

We do want to try to grow the buffer if possible, but if that attempt

The main use case right now for xdr_align_data() is to shift the page
data to the left, and in practice shrink the total XDR data buffer.
This patch ensures that we fix up the accounting for the buffer length
as we shift that data around.

This commit adds a counter of pending messages for each watch in the
struct. It is used to skip unnecessary pending messages lookup in
'unregister_xenbus_watch()'. It could also be used in 'will_handle'

Some code does not directly make 'xenbus_watch' object and call
'register_xenbus_watch()' but use 'xenbus_watch_path()' instead. This
commit adds support of 'will_handle' callback in the
'xenbus_watch_path()' and it's wrapper, 'xenbus_watch_pathfmt()'.

If handling logics of watch events are slower than the events enqueue
logic and the events can be created from the guests, the guests could
trigger memory pressure by intensively inducing the events, because it
will create a huge number of pending events that exhausting the memory.
Fortunately, some watch events could be ignored, depending on its
handler callback. For example, if the callback has interest in only one
single path, the watch wouldn't want multiple pending events. Or, some
watches could ignore events to same path.
To let such watches to volutarily help avoiding the memory pressure
situation, this commit introduces new watch callback, 'will_handle'. If
it is not NULL, it will be called for each new event just before
enqueuing it. Then, if the callback returns false, the event will be
discarded. No watch is using the callback for now, though.

On a few of our systems, I found frequent 'unshare(CLONE_NEWNET)' calls
make the number of active slab objects including 'sock_inode_cache' type
rapidly and continuously increase. As a result, memory pressure occurs.
In more detail, I made an artificial reproducer that resembles the
workload that we found the problem and reproduce the problem faster. It
merely repeats 'unshare(CLONE_NEWNET)' 50,000 times in a loop. It takes
about 2 minutes. On 40 CPU cores / 70GB DRAM machine, the available
memory continuously reduced in a fast speed (about 120MB per second,
15GB in total within the 2 minutes). Note that the issue don't
reproduce on every machine. On my 6 CPU cores machine, the problem
didn't reproduce.
'cleanup_net()' and 'fqdir_work_fn()' are functions that deallocate the
relevant memory objects. They are asynchronously invoked by the work
queues and internally use 'rcu_barrier()' to ensure safe destructions.
'cleanup_net()' works in a batched maneer in a single thread worker,
while 'fqdir_work_fn()' works for each 'fqdir_exit()' call in the
'system_wq'. Therefore, 'fqdir_work_fn()' called frequently under the
workload and made the contention for 'rcu_barrier()' high. In more
detail, the global mutex, 'rcu_state.barrier_mutex' became the
bottleneck.
This commit avoids such contention by doing the 'rcu_barrier()' and
subsequent lightweight works in a batched manner, as similar to that of
'cleanup_net()'. The fqdir hashtable destruction, which is done before
the 'rcu_barrier()', is still allowed to run in parallel for fast
processing, but this commit makes it to use a dedicated work queue
instead of the 'system_wq', to make sure that the number of threads is
bounded.

This patch adds three new netlink attributes to encapsulate a list of
expressions per set elements:
- NFTA_SET_EXPRESSIONS: this attribute provides the set definition in
terms of expressions. New set elements get attached the list of
expressions that is specified by this new netlink attribute.
- NFTA_SET_ELEM_EXPRESSIONS: this attribute allows users to restore (or
initialize) the stateful information of set elements when adding an
element to the set.
- NFTA_DYNSET_EXPRESSIONS: this attribute specifies the list of
expressions that the set element gets when it is inserted from the
packet path.

This patch replaces NFT_SET_EXPR by NFT_SET_EXT_EXPRESSIONS. This new
extension allows to attach several expressions to one set element (not
only one single expression as NFT_SET_EXPR provides). This patch
prepares for support for several expressions per set element in the
netlink userspace API.
