tracing: Have filter accept "common_cpu" to be consistent
Make filtering consistent with histograms. As "cpu" can be a field of an
event, allow for "common_cpu" to keep it from being confused with the
"cpu" field of the event.

tracing/probes: Have kprobes and uprobes use $COMM too
Both $comm and $COMM can be used to get current->comm in eprobes and the
filtering and histogram logic. Make kprobes and uprobes consistent in this
regard and allow both $comm and $COMM as well. Currently kprobes and
uprobes only handle $comm, which is inconsistent with the other utilities,
and can be confusing to users.

tracing/eprobes: Have event probes be consistent with kprobes and uprobes
Currently, if a symbol "@" is attempted to be used with an event probe
(eprobes), it will cause a NULL pointer dereference crash.
Both kprobes and uprobes can reference data other than the main registers.
Such as immediate address, symbols and the current task name. Have eprobes
do the same thing.
For "comm", if "comm" is used and the event being attached to does not
have the "comm" field, then make it the "$comm" that kprobes has. This is
consistent to the way histograms and filters work.

tracing/eprobes: Fix reading of string fields
Currently when an event probe (eprobe) hooks to a string field, it does
not display it as a string, but instead as a number. This makes the field
rather useless. Handle the different kinds of strings, dynamic, static,
relational/dynamic etc.
Now when a string field is used, the ":string" type can be used to display
it:
echo "e:sw sched/sched_switch comm=$next_comm:string" > dynamic_events

tracing/eprobes: Do not hardcode $comm as a string
The variable $comm is hard coded as a string, which is true for both
kprobes and uprobes, but for event probes (eprobes) it is a field name. In
most cases the "comm" field would be a string, but there's no guarantee of
that fact.
Do not assume that comm is a string. Not to mention, it currently forces
comm fields to fault, as string processing for event probes is currently
broken.

tracing/eprobes: Do not allow eprobes to use $stack, or % for regs
While playing with event probes (eprobes), I tried to see what would
happen if I attempted to retrieve the instruction pointer (%rip) knowing
that event probes do not use pt_regs. The result was:

fail if an event probe is used.

ftrace: Fix NULL pointer dereference in is_ftrace_trampoline when ftrace is dead
ftrace_startup does not remove ops from ftrace_ops_list when ftrace_startup_enable fails: register_ftrace_function ftrace_startup __register_ftrace_function ... add_ftrace_ops(&ftrace_ops_list, ops) ... ... ftrace_startup_enable // if ftrace failed to modify, ftrace_disabled is set to 1 ... return 0 // ops is in the ftrace_ops_list. When ftrace_disabled = 1, unregister_ftrace_function simply returns without doing anything: unregister_ftrace_function ftrace_shutdown if (unlikely(ftrace_disabled)) return -ENODEV; // return here, __unregister_ftrace_function is not executed, // as a result, ops is still in the ftrace_ops_list __unregister_ftrace_function ...

tracing/perf: Fix double put of trace event when init fails
If in perf_trace_event_init(), the perf_trace_event_open() fails, then it
will call perf_trace_event_unreg() which will not only unregister the perf
trace event, but will also call the put() function of the tp_event.
The problem here is that the trace_event_try_get_ref() is called by the
caller of perf_trace_event_init() and if perf_trace_event_init() returns a
failure, it will then call trace_event_put(). But since the
perf_trace_event_unreg() already called the trace_event_put() function, it
triggers a WARN_ON().
WARNING: CPU: 1 PID: 30309 at kernel/trace/trace_dynevent.c:46 trace_event_dyn_put_ref+0x15/0x20
If perf_trace_event_reg() does not call the trace_event_try_get_ref() then
the perf_trace_event_unreg() should not be calling trace_event_put(). This
breaks symmetry and causes bugs like these.
Pull out the trace_event_put() from perf_trace_event_unreg() and call it
in the locations that perf_trace_event_unreg() is called. This not only
fixes this bug, but also brings back the proper symmetry of the reg/unreg
vs get/put logic.

tracing: React to error return from traceprobe_parse_event_name()
The function traceprobe_parse_event_name() may set the first two function arguments to a non-null value and still return -EINVAL to indicate an unsuccessful completion of the function. Hence, it is not sufficient to just check the result of the two function arguments for being not null, but the return value also needs to be checked. Commit |

net: Fix suspicious RCU usage in bpf_sk_reuseport_detach()
bpf_sk_reuseport_detach() calls __rcu_dereference_sk_user_data_with_flags()
to obtain the value of sk->sk_user_data, but that function is only usable
if the RCU read lock is held, and neither that function nor any of its
callers hold it.
Fix this by adding a new helper, __locked_read_sk_user_data_with_flags()
that checks to see if sk->sk_callback_lock() is held and use that here
instead.
Alternatively, making __rcu_dereference_sk_user_data_with_flags() use
rcu_dereference_checked() might suffice.
Without this, the following warning can be occasionally observed:

Including fixes from bluetooth, bpf, can and netfilter.
A little longer PR than usual but it's all fixes, no late features. It's long partially because of timing, and partially because of follow ups to stuff that got merged a week or so before the merge window and wasn't as widely tested.

bpf: Only allow sleepable program for resched-able iterator
When a sleepable program is attached to a hash map iterator, might_fault() will report "BUG: sleeping function called from invalid context..." if CONFIG_DEBUG_ATOMIC_SLEEP is enabled. The reason is that rcu_read_lock() is held in bpf_hash_map_seq_next() and won't be released until all elements are traversed or bpf_hash_map_seq_stop() is called. Fixing it by reusing BPF_ITER_RESCHED to indicate that only non-sleepable program is allowed for iterator without BPF_ITER_RESCHED. We can revise bpf_iter_link_attach() later if there are other conditions which may cause rcu_read_lock() or spin_lock() issues.

bpf: Acquire map uref in .init_seq_private for hash map iterator
bpf_iter_attach_map() acquires a map uref, and the uref may be released
before or in the middle of iterating map elements. For example, the uref
could be released in bpf_iter_detach_map() as part of
bpf_link_release(), or could be released in bpf_map_put_with_uref() as
part of bpf_map_release().
So acquiring an extra map uref in bpf_iter_init_hash_map() and
releasing it in bpf_iter_fini_hash_map().

bpf: Acquire map uref in .init_seq_private for array map iterator
bpf_iter_attach_map() acquires a map uref, and the uref may be released
before or in the middle of iterating map elements. For example, the uref
could be released in bpf_iter_detach_map() as part of
bpf_link_release(), or could be released in bpf_map_put_with_uref() as
part of bpf_map_release().
Alternative fix is acquiring an extra bpf_link reference just like
a pinned map iterator does, but it introduces unnecessary dependency
on bpf_link instead of bpf_map.
So choose another fix: acquiring an extra map uref in .init_seq_private
for array map iterator.

bpf: Disallow bpf programs call prog_run command.
The verifier cannot perform sufficient validation of bpf_attr->test.ctx_in
pointer, therefore bpf programs should not be allowed to call BPF_PROG_RUN
command from within the program.
To fix this issue split bpf_sys_bpf() bpf helper into normal kern_sys_bpf()
kernel function that can only be used by the kernel light skeleton directly.

bpf: Don't reinit map value in prealloc_lru_pop
The LRU map that is preallocated may have its elements reused while
another program holds a pointer to it from bpf_map_lookup_elem. Hence,
only check_and_free_fields is appropriate when the element is being
deleted, as it ensures proper synchronization against concurrent access
of the map value. After that, we cannot call check_and_init_map_value
again as it may rewrite bpf_spin_lock, bpf_timer, and kptr fields while
they can be concurrently accessed from a BPF program.
This is safe to do as when the map entry is deleted, concurrent access
is protected against by check_and_free_fields, i.e. an existing timer
would be freed, and any existing kptr will be released by it. The
program can create further timers and kptrs after check_and_free_fields,
but they will eventually be released once the preallocated items are
freed on map destruction, even if the item is never reused again. Hence,
the deleted item sitting in the free list can still have resources
attached to it, and they would never leak.
With spin_lock, we never touch the field at all on delete or update, as
we may end up modifying the state of the lock. Since the verifier
ensures that a bpf_spin_lock call is always paired with bpf_spin_unlock
call, the program will eventually release the lock so that on reuse the
new user of the value can take the lock.
Essentially, for the preallocated case, we must assume that the map
value may always be in use by the program, even when it is sitting in
the freelist, and handle things accordingly, i.e. use proper
synchronization inside check_and_free_fields, and never reinitialize the
special fields when it is reused on update.

time: Correct the prototype of ns_to_kernel_old_timeval and ns_to_timespec64
In ns_to_kernel_old_timeval() definition, the function argument is defined
with const identifier in kernel/time/time.c, but the prototype in
include/linux/time32.h looks different.
- The function is defined in kernel/time/time.c as below:
struct __kernel_old_timeval ns_to_kernel_old_timeval(const s64 nsec)
- The function is decalared in include/linux/time32.h as below:
extern struct __kernel_old_timeval ns_to_kernel_old_timeval(s64 nsec);
Because the variable of arithmethic types isn't modified in the calling scope,
there's no need to mark arguments as const, which was already mentioned during
review (Link[1) of the original patch.
Likewise remove the "const" keyword in both definition and declaration of
ns_to_timespec64() as requested by Arnd (Link[2]).

remoteproc updates for v5.20
This introduces support for the remoteproc on Mediatek MT8188, and enables caches for MT8186 SCP. It adds support for PRU cores found on the TI K3 AM62x SoCs. It moves the recovery work after a firmware crash to an unbound workqueue, to allow recovery to happen in parallel. A new DMA API is introduced to release dma_mem for a device. It adds support a panic handler for the Qualcomm modem remoteproc, with the goal of having caches flushed in memory dumps for post-mortem debugging and it introduces a mechanism to wait for the modem firmware on SM8450 to decrypt part of its memory for post-mortem debugging. Qualcomm sysmon is restricted to only inform remote processors about peers that are actually running, to avoid a race where Linux tries to notify a recovering remote processor about its peers new state. A mechanism for waiting for the sysmon connection to be established is also introduced, to avoid out-of-sync updates for rapidly restarting remote processors. A number of Devicetree binding cleanups and conversions to YAML are introduced, to facilitate Devicetree validation. Lastly it introduces a number of smaller fixes and cleanups in the core and a few different drivers. -----BEGIN PGP SIGNATURE----- iQJPBAABCAA5FiEEBd4DzF816k8JZtUlCx85Pw2ZrcUFAmLxXTUbHGJqb3JuLmFu ZGVyc3NvbkBsaW5hcm8ub3JnAAoJEAsfOT8Nma3F6lcQAKEAtkd7dRChx5Y11h8J BdUmqYTGrlZCfZhGePgUgm9KXvf+BwjnYgZGNPVsno0h9/taY6pWggGz1/hMeD97 oTFrzZreOEHmrB7tKCQmzKdHzlVaf1aMifzz1BkICH+TRG2t/V3ycr+KJhyCK6IV CcsQ6D4FRdVDTWHEizWRewO7uFzaA3CWlr7uSY99aDMXikxSSGU7TgkH8ac04TU/ Z1+X2uClOa7IzaQX6dSm5lzZGDACatA0+WLFBf6LlEC2XtywKxPHq60QjWQwuXth /5mljBbIyW+5Qblm1r1gaipOCd6bGUvlY+0TdqbLlK8LpNIpDjFrt1mrmT4N2T+6 OAEyXglFvqHG8qjDafew5SxOEYbmFCMJ/oY+akNmpKS7Hhwx3AHeiZJdtu+bDY3O JeMQVCqrdMbrdBTNPJEjkTnhWCu1fPTn8STGaAEHgxsOPkarEtk37DuEy6KcV4It RTFY4mfnJrTfNeFpm60tOxg/zGYTjXol7uqY7BUTB7bV82W5+UTVGlpO8ayHvxru MwtN0HIDH/liXEsbt8INATXTEiTwJmEiqga53/EEWhMtnor3/xE2e26TZwzfq3sB Ue8TXnuQEN+v/ThHHvjyOZH0MONivYiW6iHkAuzq0RdnHIVDrFD/YQusWpxj7uuM nuk9OY0SbxMvUXIFKucg7zXJ =gbAX -----END PGP SIGNATURE----- Merge tag 'rproc-v5.20' of git://git.kernel.org/pub/scm/linux/kernel/git/remoteproc/linux Pull remoteproc updates from Bjorn Andersson: "This introduces support for the remoteproc on Mediatek MT8188, and enables caches for MT8186 SCP.

Modules updates for 6.0
For the 6.0 merge window the modules code shifts to cleanup and minor fixes effort. This is becomes much easier to do and review now due to the code split to its own directory from effort on the last kernel release. I expect to see more of this with time and as we expand on test coverage in the future. The cleanups and fixes come from usual suspects such as Christophe Leroy and Aaron Tomlin but there are also some other contributors. One particular minor fix worth mentioning is from Helge Deller, where he spotted a *forever* incorrect natural alignment on both ELF section header tables: * .altinstructions * __bug_table sections A lot of back and forth went on in trying to determine the ill effects of this misalignment being present for years and it has been determined there should be no real ill effects unless you have a buggy exception handler. Helge actually hit one of these buggy exception handlers on parisc which is how he ended up spotting this issue. When implemented correctly these paths with incorrect misalignment would just mean a performance penalty, but given that we are dealing with alternatives on modules and with the __bug_table (where info regardign BUG()/WARN() file/line information associated with it is stored) this really shouldn't be a big deal. The only other change with mentioning is the kmap() with kmap_local_page() and my only concern with that was on what is done after preemption, but the virtual addresses are restored after preemption. This is only used on module decompression. This all has sit on linux-next for a while except the kmap stuff which has been there for 3 weeks. -----BEGIN PGP SIGNATURE----- iQJGBAABCgAwFiEENnNq2KuOejlQLZofziMdCjCSiKcFAmLxL4gSHG1jZ3JvZkBr ZXJuZWwub3JnAAoJEM4jHQowkoin8AYP/iv/Oh/Zzh4UvZzkkOSzhf1qDgGhjFb0 aFIODZzpEfZ5ix5GcLapB8/QIwQgxiIRa3WkTMc0uyv+mddlbKuILFnI9A1I+TQe N4gmKeYXwWRyxLa6y7/B3lVzuLxf4DpcxfS2c3A65MkYi09XPA9oXCy7JjzsmEiZ z2Lu8lTe6hg8VarBTogHBxiEU7ybfDCnHWj7/Oe6zz8tS/R0i0ndNBu9xmaCqSh7 QC8++eqCaS+zfW0uTmnGDo1/zWLBblCZ5HAHG8bLlPHezUbekNz6G1D4CVwFyNQ8 wy1Gjy8nFWc+rwUl1CTgJ+A7wodGrMCyt5SmcNUVBOWdlSmli5vFJp61ET6UdrV+ +8owATwwIm8hbkIAI4037j7pMgrO27d130GRxFwgG9GNoqew2AM7y/9HrlmW49PE IqJA4Pm3zg26IhLIRcH7jLg3oKGuFf0nkMTDoooI5a9DlcsCXPuGd0FBw2WbR71D Px6dlVoAW0NrP2tm8YzkTKIT+aN+UId4Vdi2oFs1t8Sye/U+LCjvwrXPk13pZKdR VxfM1oVxeRwiAUq0VuIrnj7windF5Mpy2hDLHeWjzQmLcEGAtCYEGyxKTBkNTtPt gm9XBzT6Rbzi+Sc++ZoHYHe1g4T66sjYOp4N90sRRMD3FR97ZyW8eD01gwf6p1Uy aCOrA+sRHK3F =hPvl -----END PGP SIGNATURE----- Merge tag 'modules-6.0-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/mcgrof/linux Pull module updates from Luis Chamberlain: "For the 6.0 merge window the modules code shifts to cleanup and minor fixes effort.

Tracing updates for 5.20 / 6.0
- Runtime verification infrastructure This is the biggest change for this pull request. It introduces the runtime verification that is necessary for running Linux on safety critical systems. It allows for deterministic automata models to be inserted into the kernel that will attach to tracepoints, where the information on these tracepoints will move the model from state to state. If a state is encountered that does not belong to the model, it will then activate a given reactor, that could just inform the user or even panic the kernel (for which safety critical systems will detect and can recover from). - Two monitor models are also added: Wakeup In Preemptive (WIP - not to be confused with "work in progress"), and Wakeup While Not Running (WWNR). - Added __vstring() helper to the TRACE_EVENT() macro to replace several vsnprintf() usages that were all doing it wrong. - eprobes now can have their event autogenerated when the event name is left off. - The rest is various cleanups and fixes. -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCYu0yzRQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qj4HAP4tQtV55rjj4DQ5XIXmtI3/64PmyRSJ +y4DEXi1UvEUCQD/QAuQfWoT/7gh35ltkfeS4t3ockzy14rrkP5drZigiQA= =kEtM -----END PGP SIGNATURE----- Merge tag 'trace-v6.0' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace Pull tracing updates from Steven Rostedt: - Runtime verification infrastructure This is the biggest change here.

audit, io_uring, io-wq: Fix memory leak in io_sq_thread() and io_wqe_worker()
Currently @audit_context is allocated twice for io_uring workers:
1. copy_process() calls audit_alloc();
2. io_sq_thread() or io_wqe_worker() calls audit_alloc_kernel() (which
is effectively audit_alloc()) and overwrites @audit_context,
causing:
BUG: memory leak

Then,
3. io_sq_thread() or io_wqe_worker() frees @audit_context using
audit_free();
4. do_exit() eventually calls audit_free() again, which is okay
because audit_free() does a NULL check.
As suggested by Paul Moore, fix it by deleting audit_alloc_kernel() and
redundant audit_free() calls.
