[ Upstream commit 43cf0e05089afe23dac74fa6e1e109d49f2903c4 ]
The events hugepage_set_pmd, hugepage_set_pud, hugepage_update_pmd and
hugepage_update_pud are only called when CONFIG_PPC_BOOK3S_64 is defined.
As each event can take up to 5K regardless if they are used or not, it's
best not to define them when they are not used. Add #ifdef around these
events when they are not used.

[ Upstream commit 647fe16b46999258ce1aec41f4bdeabb4f0cc8e7 ]
As the trace event powernv_throttle is only used by the powernv code, move
it to a separate include file and have that code directly enable it.
Trace events can take up around 5K of memory when they are defined
regardless if they are used or not. It wastes memory to have them defined
in configurations where the tracepoint is not used.

[ Upstream commit 2fd895842d49c23137ae48252dd211e5d6d8a3ed ]
When a call is released, rxrpc takes the spinlock and removes it from
->recvmsg_q in an effort to prevent racing recvmsg() invocations from
seeing the same call. Now, rxrpc_recvmsg() only takes the spinlock when
actually removing a call from the queue; it doesn't, however, take it in
the lead up to that when it checks to see if the queue is empty. It *does*
hold the socket lock, which prevents a recvmsg/recvmsg race - but this
doesn't prevent sendmsg from ending the call because sendmsg() drops the
socket lock and relies on the call->user_mutex.
Fix this by firstly removing the bit in rxrpc_release_call() that dequeues
the released call and, instead, rely on recvmsg() to simply discard
released calls (done in a preceding fix).
Secondly, rxrpc_notify_socket() is abandoned if the call is already marked
as released rather than trying to be clever by setting both pointers in
call->recvmsg_link to NULL to trick list_empty(). This isn't perfect and
can still race, resulting in a released call on the queue, but recvmsg()
will now clean that up.

[ Upstream commit 962fb1f651c2cf2083e0c3ef53ba69e3b96d3fbc ]
If a call receives an event (such as incoming data), the call gets placed
on the socket's queue and a thread in recvmsg can be awakened to go and
process it. Once the thread has picked up the call off of the queue,
further events will cause it to be requeued, and once the socket lock is
dropped (recvmsg uses call->user_mutex to allow the socket to be used in
parallel), a second thread can come in and its recvmsg can pop the call off
the socket queue again.
In such a case, the first thread will be receiving stuff from the call and
the second thread will be blocked on call->user_mutex. The first thread
can, at this point, process both the event that it picked call for and the
event that the second thread picked the call for and may see the call
terminate - in which case the call will be "released", decoupling the call
from the user call ID assigned to it (RXRPC_USER_CALL_ID in the control
message).
The first thread will return okay, but then the second thread will wake up
holding the user_mutex and, if it sees that the call has been released by
the first thread, it will BUG thusly:
kernel BUG at net/rxrpc/recvmsg.c:474!
Fix this by just dequeuing the call and ignoring it if it is seen to be
already released. We can't tell userspace about it anyway as the user call
ID has become stale.

commit 89635eae076cd8eaa5cb752f66538c9dc6c9fdc3 upstream.
When netfslib is issuing subrequests, the subrequests start processing
immediately and may complete before we reach the end of the issuing
function. At the end of the issuing function we set NETFS_RREQ_ALL_QUEUED
to indicate to the collector that we aren't going to issue any more subreqs
and that it can do the final notifications and cleanup.
Now, this isn't a problem if the request is synchronous
(NETFS_RREQ_OFFLOAD_COLLECTION is unset) as the result collection will be
done in-thread and we're guaranteed an opportunity to run the collector.
However, if the request is asynchronous, collection is primarily triggered
by the termination of subrequests queuing it on a workqueue. Now, a race
can occur here if the app thread sets ALL_QUEUED after the last subrequest
terminates.
This can happen most easily with the copy2cache code (as used by Ceph)
where, in the collection routine of a read request, an asynchronous write
request is spawned to copy data to the cache. Folios are added to the
write request as they're unlocked, but there may be a delay before
ALL_QUEUED is set as the write subrequests may complete before we get
there.
If all the write subreqs have finished by the ALL_QUEUED point, no further
events happen and the collection never happens, leaving the request
hanging.
Fix this by queuing the collector after setting ALL_QUEUED. This is a bit
heavy-handed and it may be sufficient to do it only if there are no extant
subreqs.
Also add a tracepoint to cross-reference both requests in a copy-to-request
operation and add a trace to the netfs_rreq tracepoint to indicate the
setting of ALL_QUEUED.

[ Upstream commit 9df7b5ebead649b00bf9a53a798e4bf83a1318fd ]
If a netfs request finishes during the pause loop, it will have the ref
that belongs to the IN_PROGRESS flag removed at that point - however, if it
then goes to the final wait loop, that will *also* put the ref because it
sees that the IN_PROGRESS flag is clear and incorrectly assumes that this
happened when it called the collector.
In fact, since IN_PROGRESS is clear, we shouldn't call the collector again
since it's done all the cleanup, such as calling ->ki_complete().
Fix this by making netfs_collect_in_app() just return, indicating that
we're done if IN_PROGRESS is removed.

[ Upstream commit db26d62d79e4068934ad0dccdb92715df36352b9 ]
On cifs, "DIO reads" (specified by O_DIRECT) need to be differentiated from
"unbuffered reads" (specified by cache=none in the mount parameters). The
difference is flagged in the protocol and the server may behave
differently: Windows Server will, for example, mandate that DIO reads are
block aligned.
Fix this by adding a NETFS_UNBUFFERED_READ to differentiate this from
NETFS_DIO_READ, parallelling the write differentiation that already exists.
cifs will then do the right thing.

[ Upstream commit 20d72b00ca814d748f5663484e5c53bb2bf37a3a ]
When the netfs_io_request struct's work item is queued, it must be supplied
with a ref to the work item struct to prevent it being deallocated whilst
on the queue or whilst it is being processed. This is tricky to manage as
we have to get a ref before we try and queue it and then we may find it's
already queued and is thus already holding a ref - in which case we have to
try and get rid of the ref again.
The problem comes if we're in BH or IRQ context and need to drop the ref:
if netfs_put_request() reduces the count to 0, we have to do the cleanup -
but the cleanup may need to wait.
Fix this by adding a new work item to the request, ->cleanup_work, and
dispatching that when the refcount hits zero. That can then synchronously
cancel any outstanding work on the main work item before doing the cleanup.
Adding a new work item also deals with another problem upstream where it's
sometimes changing the work func in the put function and requeuing it -
which has occasionally in the past caused the cleanup to happen
incorrectly.
As a bonus, this allows us to get rid of the 'was_async' parameter from a
bunch of functions. This indicated whether the put function might not be
permitted to sleep.

btrfs_prelim_ref() calls the old and new reference variables in the
incorrect order. This causes a NULL pointer dereference because oldref
is passed as NULL to trace_btrfs_prelim_ref_insert().
Note, trace_btrfs_prelim_ref_insert() is being called with newref as
oldref (and oldref as NULL) on purpose in order to print out
the values of newref.
To reproduce:

Pull tracing updates from Steven Rostedt:
- Add option traceoff_after_boot
In order to debug kernel boot, it sometimes is helpful to enable
tracing via the kernel command line. Unfortunately, by the time the
login prompt appears, the trace is overwritten by the init process
and other user space start up applications.
Adding a "traceoff_after_boot" will disable tracing when the kernel
passes control to init which will allow developers to be able to see
the traces that occurred during boot.
- Clean up the mmflags macros that display the GFP flags in trace
events
The macros to print the GFP flags for trace events had a bit of
duplication. The code was restructured to remove duplication and in
the process it also adds some flags that were missed before.
- Removed some dead code and scripts/draw_functrace.py
draw_functrace.py hasn't worked in years and as nobody complained
about it, remove it.
- Constify struct event_trigger_ops
The event_trigger_ops is just a structure that has function pointers
that are assigned when the variables are created. These variables
should all be constants.
- Other minor clean ups and fixes

Pull latency tracing updates from Steven Rostedt:
- Add some trace events to osnoise and timerlat sample generation
This adds more information to the osnoise and timerlat tracers as
well as allows BPF programs to be attached to these locations to
extract even more data.
- Fix to DECLARE_TRACE_CONDITION() macro
It wasn't used but now will be and it happened to be broken causing
the build to fail.
- Add scheduler specification monitors to runtime verifier (RV)
This is a continuation of Daniel Bristot's work.
RV allows monitors to run and react concurrently. Running the
cumulative model is equivalent to running single components using the
same reactors, with the advantage that it's easier to point out which
specification failed in case of error.
This update introduces nested monitors to RV, in short, the sysfs
monitor folder will contain a monitor named sched, which is nothing
but an empty container for other monitors. Controlling the sched
monitor (enable, disable, set reactors) controls all nested monitors.
The following scheduling monitors are added:
- sco: scheduling context operations
Monitor to ensure sched_set_state happens only in thread context
- tss: task switch while scheduling
Monitor to ensure sched_switch happens only in scheduling context
- snroc: set non runnable on its own context
Monitor to ensure set_state happens only in the respective task's context
- scpd: schedule called with preemption disabled
Monitor to ensure schedule is called with preemption disabled
- snep: schedule does not enable preempt
Monitor to ensure schedule does not enable preempt
- sncid: schedule not called with interrupt disabled
Monitor to ensure schedule is not called with interrupt disabled

Pull networking updates from Jakub Kicinski:
"Core & protocols:
- Continue Netlink conversions to per-namespace RTNL lock
(IPv4 routing, routing rules, routing next hops, ARP ioctls)
- Continue extending the use of netdev instance locks. As a driver
opt-in protect queue operations and (in due course) ethtool
operations with the instance lock and not RTNL lock.
- Support collecting TCP timestamps (data submitted, sent, acked) in
BPF, allowing for transparent (to the application) and lower
overhead tracking of TCP RPC performance.
- Tweak existing networking Rx zero-copy infra to support zero-copy
Rx via io_uring.
- Optimize MPTCP performance in single subflow mode by 29%.
- Enable GRO on packets which went thru XDP CPU redirect (were queued
for processing on a different CPU). Improving TCP stream
performance up to 2x.
- Improve performance of contended connect() by 200% by searching for
an available 4-tuple under RCU rather than a spin lock. Bring an
additional 229% improvement by tweaking hash distribution.
- Avoid unconditionally touching sk_tsflags on RX, improving
performance under UDP flood by as much as 10%.
- Avoid skb_clone() dance in ping_rcv() to improve performance under
ping flood.
- Avoid FIB lookup in netfilter if socket is available, 20% perf win.
- Rework network device creation (in-kernel) API to more clearly
identify network namespaces and their roles. There are up to 4
namespace roles but we used to have just 2 netns pointer arguments,
interpreted differently based on context.
- Use sysfs_break_active_protection() instead of trylock to avoid
deadlocks between unregistering objects and sysfs access.
- Add a new sysctl and sockopt for capping max retransmit timeout in
TCP.
