rtmutex: Drop rt_mutex::wait_lock before scheduling
commit d33d26036a0274b472299d7dcdaa5fb34329f91b upstream.
rt_mutex_handle_deadlock() is called with rt_mutex::wait_lock held. In the
good case it returns with the lock held and in the deadlock case it emits a
warning and goes into an endless scheduling loop with the lock held, which
triggers the 'scheduling in atomic' warning.
Unlock rt_mutex::wait_lock in the dead lock case before issuing the warning
and dropping into the schedule for ever loop.
[ tglx: Moved unlock before the WARN(), removed the pointless comment,
massaged changelog, added Fixes tag ]

perf/aux: Fix AUX buffer serialization
commit 2ab9d830262c132ab5db2f571003d80850d56b2a upstream.
Ole reported that event->mmap_mutex is strictly insufficient to
serialize the AUX buffer, add a per RB mutex to fully serialize it.
Note that in the lock order comment the perf_event::mmap_mutex order
was already wrong, that is, it nesting under mmap_lock is not new with
this patch.

smp: Add missing destroy_work_on_stack() call in smp_call_on_cpu()
[ Upstream commit 77aeb1b685f9db73d276bad4bb30d48505a6fd23 ] For CONFIG_DEBUG_OBJECTS_WORK=y kernels sscs.work defined by INIT_WORK_ONSTACK() is initialized by debug_object_init_on_stack() for the debug check in __init_work() to work correctly. But this lacks the counterpart to remove the tracked object from debug objects again, which will cause a debug object warning once the stack is freed. Add the missing destroy_work_on_stack() invocation to cure that.

cgroup: Protect css->cgroup write under css_set_lock
[ Upstream commit 57b56d16800e8961278ecff0dc755d46c4575092 ] The writing of css->cgroup associated with the cgroup root in rebind_subsystems() is currently protected only by cgroup_mutex. However, the reading of css->cgroup in both proc_cpuset_show() and proc_cgroup_show() is protected just by css_set_lock. That makes the readers susceptible to racing problems like data tearing or caching. It is also a problem that can be reported by KCSAN. This can be fixed by using READ_ONCE() and WRITE_ONCE() to access css->cgroup. Alternatively, the writing of css->cgroup can be moved under css_set_lock as well which is done by this patch.

tracing: Avoid possible softlockup in tracing_iter_reset()
commit 49aa8a1f4d6800721c7971ed383078257f12e8f9 upstream.
In __tracing_open(), when max latency tracers took place on the cpu,
the time start of its buffer would be updated, then event entries with
timestamps being earlier than start of the buffer would be skipped
(see tracing_iter_reset()).
Softlockup will occur if the kernel is non-preemptible and too many
entries were skipped in the loop that reset every cpu buffer, so add
cond_resched() to avoid it.

bpf, cgroup: Assign cgroup in cgroup_sk_alloc when called from interrupt
From: Daniel Borkmann <daniel@iogearbox.net>
commit 78cc316e9583067884eb8bd154301dc1e9ee945c upstream.
If cgroup_sk_alloc() is called from interrupt context, then just assign the
root cgroup to skcd->cgroup. Prior to commit 8520e224f547 ("bpf, cgroups:
Fix cgroup v2 fallback on v1/v2 mixed mode") we would just return, and later
on in sock_cgroup_ptr(), we were NULL-testing the cgroup in fast-path, and
iff indeed NULL returning the root cgroup (v ?: &cgrp_dfl_root.cgrp). Rather
than re-adding the NULL-test to the fast-path we can just assign it once from
cgroup_sk_alloc() given v1/v2 handling has been simplified. The migration from
NULL test with returning &cgrp_dfl_root.cgrp to assigning &cgrp_dfl_root.cgrp
directly does /not/ change behavior for callers of sock_cgroup_ptr().
syzkaller was able to trigger a splat in the legacy netrom code base, where
the RX handler in nr_rx_frame() calls nr_make_new() which calls sk_alloc()
and therefore cgroup_sk_alloc() with in_interrupt() condition. Thus the NULL
skcd->cgroup, where it trips over on cgroup_sk_free() side given it expects
a non-NULL object. There are a few other candidates aside from netrom which
have similar pattern where in their accept-like implementation, they just call
to sk_alloc() and thus cgroup_sk_alloc() instead of sk_clone_lock() with the
corresponding cgroup_sk_clone() which then inherits the cgroup from the parent
socket. None of them are related to core protocols where BPF cgroup programs
are running from. However, in future, they should follow to implement a similar
inheritance mechanism.
Additionally, with a !CONFIG_CGROUP_NET_PRIO and !CONFIG_CGROUP_NET_CLASSID
configuration, the same issue was exposed also prior to 8520e224f547 due to
commit

rcu-tasks: Fix show_rcu_tasks_trace_gp_kthread buffer overflow
commit cc5645fddb0ce28492b15520306d092730dffa48 upstream.
There is a possibility of buffer overflow in
show_rcu_tasks_trace_gp_kthread() if counters, passed
to sprintf() are huge. Counter numbers, needed for this
are unrealistically high, but buffer overflow is still
possible.
Use snprintf() with buffer size instead of sprintf().

dma-debug: avoid deadlock between dma debug vs printk and netconsole
[ Upstream commit bd44ca3de49cc1badcff7a96010fa2c64f04868c ] Currently the dma debugging code can end up indirectly calling printk under the radix_lock. This happens when a radix tree node allocation fails. This is a problem because the printk code, when used together with netconsole, can end up inside the dma debugging code while trying to transmit a message over netcons. This creates the possibility of either a circular deadlock on the same CPU, with that CPU trying to grab the radix_lock twice, or an ABBA deadlock between different CPUs, where one CPU grabs the console lock first and then waits for the radix_lock, while the other CPU is holding the radix_lock and is waiting for the console lock. The trace captured by lockdep is of the ABBA variant. -> #2 (&dma_entry_hash[i].lock){-.-.}-{2:2}: _raw_spin_lock_irqsave+0x5a/0x90 debug_dma_map_page+0x79/0x180 dma_map_page_attrs+0x1d2/0x2f0 bnxt_start_xmit+0x8c6/0x1540 netpoll_start_xmit+0x13f/0x180 netpoll_send_skb+0x20d/0x320 netpoll_send_udp+0x453/0x4a0 write_ext_msg+0x1b9/0x460 console_flush_all+0x2ff/0x5a0 console_unlock+0x55/0x180 vprintk_emit+0x2e3/0x3c0 devkmsg_emit+0x5a/0x80 devkmsg_write+0xfd/0x180 do_iter_readv_writev+0x164/0x1b0 vfs_writev+0xf9/0x2b0 do_writev+0x6d/0x110 do_syscall_64+0x80/0x150 entry_SYSCALL_64_after_hwframe+0x4b/0x53 -> #0 (console_owner){-.-.}-{0:0}: __lock_acquire+0x15d1/0x31a0 lock_acquire+0xe8/0x290 console_flush_all+0x2ea/0x5a0 console_unlock+0x55/0x180 vprintk_emit+0x2e3/0x3c0 _printk+0x59/0x80 warn_alloc+0x122/0x1b0 __alloc_pages_slowpath+0x1101/0x1120 __alloc_pages+0x1eb/0x2c0 alloc_slab_page+0x5f/0x150 new_slab+0x2dc/0x4e0 ___slab_alloc+0xdcb/0x1390 kmem_cache_alloc+0x23d/0x360 radix_tree_node_alloc+0x3c/0xf0 radix_tree_insert+0xf5/0x230 add_dma_entry+0xe9/0x360 dma_map_page_attrs+0x1d2/0x2f0 __bnxt_alloc_rx_frag+0x147/0x180 bnxt_alloc_rx_data+0x79/0x160 bnxt_rx_skb+0x29/0xc0 bnxt_rx_pkt+0xe22/0x1570 __bnxt_poll_work+0x101/0x390 bnxt_poll+0x7e/0x320 __napi_poll+0x29/0x160 net_rx_action+0x1e0/0x3e0 handle_softirqs+0x190/0x510 run_ksoftirqd+0x4e/0x90 smpboot_thread_fn+0x1a8/0x270 kthread+0x102/0x120 ret_from_fork+0x2f/0x40 ret_from_fork_asm+0x11/0x20 This bug is more likely than it seems, because when one CPU has run out of memory, chances are the other has too.

ANDROID: vendor_hooks: add hooks in rwsem
these hooks are required by the following features: 1.For rwsem readers, currently only the latest reader will be recorded in sem->owner. We add hooks to record all readers which have acquired the lock, once there are UX threads blocked in the rwsem waiting list, these read_owners will be given high priority in scheduling. 2.For rwsem writer, when a writer acquires the lock, we check whether there are UX threads blocked in the rwsem wait list. If so, we give this writer a high priority in scheduling so that it can release the lock as soon as possible. Both of these features can optimize the priority inversion problem caused by rwsem and improve system responsiveness and performance. There is already a hook android_vh_rwsem_set_owner in rwsem_set_owner() to record writer owned, so the hook android_vh_record_rwsem_writer_owned in cherry pick is removed.

cgroup/cpuset: Prevent UAF in proc_cpuset_show()
commit 1be59c97c83ccd67a519d8a49486b3a8a73ca28a upstream.
An UAF can happen when /proc/cpuset is read as reported in [1].
This can be reproduced by the following methods:
1.add an mdelay(1000) before acquiring the cgroup_lock In the
cgroup_path_ns function.
2.$cat /proc/<pid>/cpuset repeatly.
3.$mount -t cgroup -o cpuset cpuset /sys/fs/cgroup/cpuset/
$umount /sys/fs/cgroup/cpuset/ repeatly.
The race that cause this bug can be shown as below:
(umount) | (cat /proc/<pid>/cpuset)
css_release | proc_cpuset_show
css_release_work_fn | css = task_get_css(tsk, cpuset_cgrp_id);
css_free_rwork_fn | cgroup_path_ns(css->cgroup, ...);
cgroup_destroy_root | mutex_lock(&cgroup_mutex);
rebind_subsystems |
cgroup_free_root |
| // cgrp was freed, UAF
| cgroup_path_ns_locked(cgrp,..);
When the cpuset is initialized, the root node top_cpuset.css.cgrp
will point to &cgrp_dfl_root.cgrp. In cgroup v1, the mount operation will
allocate cgroup_root, and top_cpuset.css.cgrp will point to the allocated
&cgroup_root.cgrp. When the umount operation is executed,
top_cpuset.css.cgrp will be rebound to &cgrp_dfl_root.cgrp.
The problem is that when rebinding to cgrp_dfl_root, there are cases
where the cgroup_root allocated by setting up the root for cgroup v1
is cached. This could lead to a Use-After-Free (UAF) if it is
subsequently freed. The descendant cgroups of cgroup v1 can only be
freed after the css is released. However, the css of the root will never
be released, yet the cgroup_root should be freed when it is unmounted.
This means that obtaining a reference to the css of the root does
not guarantee that css.cgrp->root will not be freed.
Fix this problem by using rcu_read_lock in proc_cpuset_show().
As cgroup_root is kfree_rcu after commit d23b5c577715
("cgroup: Make operations on the cgroup root_list RCU safe"),
css->cgroup won't be freed during the critical section.
To call cgroup_path_ns_locked, css_set_lock is needed, so it is safe to
replace task_get_css with task_css.

hrtimer: Prevent queuing of hrtimer without a function callback
[ Upstream commit 5a830bbce3af16833fe0092dec47b6dd30279825 ] The hrtimer function callback must not be NULL. It has to be specified by the call side but it is not validated by the hrtimer code. When a hrtimer is queued without a function callback, the kernel crashes with a null pointer dereference when trying to execute the callback in __run_hrtimer(). Introduce a validation before queuing the hrtimer in hrtimer_start_range_ns().

sched: walt: add support for sibling clusters
There are systems where two different cluster shows similar power/perf behavior, to handle such system add support to treat such clusters as siblings and balance load between them during placements(load balancing flow is not touched in the current implementation). To enable/configure: /proc/sys/walt/sched_sibling_cluster Tunable is a 4 integer quadruple where each position represents a cluster and setting '-1' disables sibling cluster and setting any valid cluster if enables it.

Looking at the padata_mt_helper() function, the only way a divide-by-0
panic can happen is when ps->chunk_size is 0. The way that chunk_size is
initialized in padata_do_multithreaded(), chunk_size can be 0 when the
min_chunk in the passed-in padata_mt_job structure is 0.
Fix this divide-by-0 panic by making sure that chunk_size will be at least
1 no matter what the input parameters are.

tracing: Fix overflow in get_free_elt()
commit bcf86c01ca4676316557dd482c8416ece8c2e143 upstream.
"tracing_map->next_elt" in get_free_elt() is at risk of overflowing.
Once it overflows, new elements can still be inserted into the tracing_map
even though the maximum number of elements (`max_elts`) has been reached.
Continuing to insert elements after the overflow could result in the
tracing_map containing "tracing_map->max_size" elements, leaving no empty
entries.
If any attempt is made to insert an element into a full tracing_map using
`__tracing_map_insert()`, it will cause an infinite loop with preemption
disabled, leading to a CPU hang problem.
Fix this by preventing any further increments to "tracing_map->next_elt"
once it reaches "tracing_map->max_elt".

genirq/irqdesc: Honor caller provided affinity in alloc_desc()
commit edbbaae42a56f9a2b39c52ef2504dfb3fb0a7858 upstream.
Currently, whenever a caller is providing an affinity hint for an
interrupt, the allocation code uses it to calculate the node and copies the
cpumask into irq_desc::affinity.
If the affinity for the interrupt is not marked 'managed' then the startup
of the interrupt ignores irq_desc::affinity and uses the system default
affinity mask.
Prevent this by setting the IRQD_AFFINITY_SET flag for the interrupt in the
allocator, which causes irq_setup_affinity() to use irq_desc::affinity on
interrupt startup if the mask contains an online CPU.

tick/broadcast: Move per CPU pointer access into the atomic section
commit 6881e75237a84093d0986f56223db3724619f26e upstream.
The recent fix for making the take over of the broadcast timer more
reliable retrieves a per CPU pointer in preemptible context.
This went unnoticed as compilers hoist the access into the non-preemptible
region where the pointer is actually used. But of course it's valid that
the compiler keeps it at the place where the code puts it which rightfully
triggers:
BUG: using smp_processor_id() in preemptible [00000000] code:

dma: fix call order in dmam_free_coherent
[ Upstream commit 28e8b7406d3a1f5329a03aa25a43aa28e087cb20 ]
dmam_free_coherent() frees a DMA allocation, which makes the
freed vaddr available for reuse, then calls devres_destroy()
to remove and free the data structure used to track the DMA
allocation. Between the two calls, it is possible for a
concurrent task to make an allocation with the same vaddr
and add it to the devres list.
If this happens, there will be two entries in the devres list
with the same vaddr and devres_destroy() can free the wrong
entry, triggering the WARN_ON() in dmam_match.
Fix by destroying the devres entry before freeing the DMA
allocation.

kernel: rerun task_work while freezing in get_signal()
commit 943ad0b62e3c21f324c4884caa6cb4a871bca05c upstream. io_uring can asynchronously add a task_work while the task is getting freezed. TIF_NOTIFY_SIGNAL will prevent the task from sleeping in do_freezer_trap(), and since the get_signal()'s relock loop doesn't retry task_work, the task will spin there not being able to sleep until the freezing is cancelled / the task is killed / etc. Run task_works in the freezer path. Keep the patch small and simple so it can be easily back ported, but we might need to do some cleaning after and look if there are other places with similar problems.

watchdog/perf: properly initialize the turbo mode timestamp and rearm counter
commit f944ffcbc2e1c759764850261670586ddf3bdabb upstream.
For systems on which the performance counter can expire early due to turbo
modes the watchdog handler has a safety net in place which validates that
since the last watchdog event there has at least 4/5th of the watchdog
period elapsed.
This works reliably only after the first watchdog event because the per
CPU variable which holds the timestamp of the last event is never
initialized.
So a first spurious event will validate against a timestamp of 0 which
results in a delta which is likely to be way over the 4/5 threshold of the
period. As this might happen before the first watchdog hrtimer event
increments the watchdog counter, this can lead to false positives.
Fix this by initializing the timestamp before enabling the hardware event.
Reset the rearm counter as well, as that might be non zero after the
watchdog was disabled and reenabled.

sched/fair: Use all little CPUs for CPU-bound workloads
commit 3af7524b14198f5159a86692d57a9f28ec9375ce upstream.
Running N CPU-bound tasks on an N CPUs platform:
- with asymmetric CPU capacity
- not being a DynamIq system (i.e. having a PKG level sched domain
without the SD_SHARE_PKG_RESOURCES flag set)
.. might result in a task placement where two tasks run on a big CPU
and none on a little CPU. This placement could be more optimal by
using all CPUs.
Testing platform:
Juno-r2:
- 2 big CPUs (1-2), maximum capacity of 1024
- 4 little CPUs (0,3-5), maximum capacity of 383
Testing workload ([1]):
Spawn 6 CPU-bound tasks. During the first 100ms (step 1), each tasks
is affine to a CPU, except for:
- one little CPU which is left idle.
- one big CPU which has 2 tasks affine.
After the 100ms (step 2), remove the cpumask affinity.
Behavior before the patch:
During step 2, the load balancer running from the idle CPU tags sched
domains as:
- little CPUs: 'group_has_spare'. Cf. group_has_capacity() and
group_is_overloaded(), 3 CPU-bound tasks run on a 4 CPUs
sched-domain, and the idle CPU provides enough spare capacity
regarding the imbalance_pct
- big CPUs: 'group_overloaded'. Indeed, 3 tasks run on a 2 CPUs
sched-domain, so the following path is used:
group_is_overloaded()
\-if (sgs->sum_nr_running <= sgs->group_weight) return true;
The following path which would change the migration type to
'migrate_task' is not taken:
calculate_imbalance()
\-if (env->idle != CPU_NOT_IDLE && env->imbalance == 0)
as the local group has some spare capacity, so the imbalance
is not 0.
The migration type requested is 'migrate_util' and the busiest
runqueue is the big CPU's runqueue having 2 tasks (each having a
utilization of 512). The idle little CPU cannot pull one of these
task as its capacity is too small for the task. The following path
is used:
detach_tasks()
\-case migrate_util:
\-if (util > env->imbalance) goto next;
After the patch:
As the number of failed balancing attempts grows (with
'nr_balance_failed'), progressively make it easier to migrate
a big task to the idling little CPU. A similar mechanism is
used for the 'migrate_load' migration type.
Improvement:
Running the testing workload [1] with the step 2 representing
a ~10s load for a big CPU:
Before patch: ~19.3s
After patch: ~18s (-6.7%)

sched/fair: set_load_weight() must also call reweight_task() for SCHED_IDLE tasks
commit d329605287020c3d1c3b0dadc63d8208e7251382 upstream.
When a task's weight is being changed, set_load_weight() is called with
@update_load set. As weight changes aren't trivial for the fair class,
set_load_weight() calls fair.c::reweight_task() for fair class tasks.
However, set_load_weight() first tests task_has_idle_policy() on entry and
skips calling reweight_task() for SCHED_IDLE tasks. This is buggy as
SCHED_IDLE tasks are just fair tasks with a very low weight and they would
incorrectly skip load, vlag and position updates.
Fix it by updating reweight_task() to take struct load_weight as idle weight
can't be expressed with prio and making set_load_weight() call
reweight_task() for SCHED_IDLE tasks too when @update_load is set.

tick/broadcast: Make takeover of broadcast hrtimer reliable
commit f7d43dd206e7e18c182f200e67a8db8c209907fa upstream.
Running the LTP hotplug stress test on a aarch64 machine results in
rcu_sched stall warnings when the broadcast hrtimer was owned by the
un-plugged CPU. The issue is the following:
CPU1 (owns the broadcast hrtimer) CPU2
tick_broadcast_enter()
// shutdown local timer device
broadcast_shutdown_local()
...
tick_broadcast_exit()
clockevents_switch_state(dev, CLOCK_EVT_STATE_ONESHOT)
// timer device is not programmed
cpumask_set_cpu(cpu, tick_broadcast_force_mask)
initiates offlining of CPU1
take_cpu_down()
/*
* CPU1 shuts down and does not
* send broadcast IPI anymore
*/
takedown_cpu()
hotplug_cpu__broadcast_tick_pull()
// move broadcast hrtimer to this CPU
clockevents_program_event()
bc_set_next()
hrtimer_start()
/*
* timer device is not programmed
* because only the first expiring
* timer will trigger clockevent
* device reprogramming
*/
What happens is that CPU2 exits broadcast mode with force bit set, then the
local timer device is not reprogrammed and CPU2 expects to receive the
expired event by the broadcast IPI. But this does not happen because CPU1
is offlined by CPU2. CPU switches the clockevent device to ONESHOT state,
but does not reprogram the device.
The subsequent reprogramming of the hrtimer broadcast device does not
program the clockevent device of CPU2 either because the pending expiry
time is already in the past and the CPU expects the event to be delivered.
As a consequence all CPUs which wait for a broadcast event to be delivered
are stuck forever.
Fix this issue by reprogramming the local timer device if the broadcast
force bit of the CPU is set so that the broadcast hrtimer is delivered.

bpf: annotate BTF show functions with __printf
[ Upstream commit b3470da314fd8018ee237e382000c4154a942420 ]
-Werror=suggest-attribute=format warns about two functions
in kernel/bpf/btf.c [1]; add __printf() annotations to silence
these warnings since for CONFIG_WERROR=y they will trigger
build failures.

perf: Prevent passing zero nr_pages to rb_alloc_aux()
[ Upstream commit dbc48c8f41c208082cfa95e973560134489e3309 ]
nr_pages is unsigned long but gets passed to rb_alloc_aux() as an int,
and is stored as an int.
Only power-of-2 values are accepted, so if nr_pages is a 64_bit value, it
will be passed to rb_alloc_aux() as zero.
That is not ideal because:
1. the value is incorrect
2. rb_alloc_aux() is at risk of misbehaving, although it manages to
return -ENOMEM in that case, it is a result of passing zero to get_order()
even though the get_order() result is documented to be undefined in that
case.
Fix by simply validating the maximum supported value in the first place.
Use -ENOMEM error code for consistency with the current error code that
is returned in that case.

perf: Fix perf_aux_size() for greater-than 32-bit size
[ Upstream commit 3df94a5b1078dfe2b0c03f027d018800faf44c82 ]
perf_buffer->aux_nr_pages uses a 32-bit type, so a cast is needed to
calculate a 64-bit size.

bpf: Fix overrunning reservations in ringbuf
commit cfa1a2329a691ffd991fcf7248a57d752e712881 upstream.
The BPF ring buffer internally is implemented as a power-of-2 sized circular
buffer, with two logical and ever-increasing counters: consumer_pos is the
consumer counter to show which logical position the consumer consumed the
data, and producer_pos which is the producer counter denoting the amount of
data reserved by all producers.
Each time a record is reserved, the producer that "owns" the record will
successfully advance producer counter. In user space each time a record is
read, the consumer of the data advanced the consumer counter once it finished
processing. Both counters are stored in separate pages so that from user
space, the producer counter is read-only and the consumer counter is read-write.
One aspect that simplifies and thus speeds up the implementation of both
producers and consumers is how the data area is mapped twice contiguously
back-to-back in the virtual memory, allowing to not take any special measures
for samples that have to wrap around at the end of the circular buffer data
area, because the next page after the last data page would be first data page
again, and thus the sample will still appear completely contiguous in virtual
memory.
Each record has a struct bpf_ringbuf_hdr { u32 len; u32 pg_off; } header for
book-keeping the length and offset, and is inaccessible to the BPF program.
Helpers like bpf_ringbuf_reserve() return `(void *)hdr + BPF_RINGBUF_HDR_SZ`
for the BPF program to use. Bing-Jhong and Muhammad reported that it is however
possible to make a second allocated memory chunk overlapping with the first
chunk and as a result, the BPF program is now able to edit first chunk's
header.
For example, consider the creation of a BPF_MAP_TYPE_RINGBUF map with size
of 0x4000. Next, the consumer_pos is modified to 0x3000 /before/ a call to
bpf_ringbuf_reserve() is made. This will allocate a chunk A, which is in
[0x0,0x3008], and the BPF program is able to edit [0x8,0x3008]. Now, lets
allocate a chunk B with size 0x3000. This will succeed because consumer_pos
was edited ahead of time to pass the `new_prod_pos - cons_pos > rb->mask`
check. Chunk B will be in range [0x3008,0x6010], and the BPF program is able
to edit [0x3010,0x6010]. Due to the ring buffer memory layout mentioned
earlier, the ranges [0x0,0x4000] and [0x4000,0x8000] point to the same data
pages. This means that chunk B at [0x4000,0x4008] is chunk A's header.
bpf_ringbuf_submit() / bpf_ringbuf_discard() use the header's pg_off to then
locate the bpf_ringbuf itself via bpf_ringbuf_restore_from_rec(). Once chunk
B modified chunk A's header, then bpf_ringbuf_commit() refers to the wrong
page and could cause a crash.
Fix it by calculating the oldest pending_pos and check whether the range
from the oldest outstanding record to the newest would span beyond the ring
buffer size. If that is the case, then reject the request. We've tested with
the ring buffer benchmark in BPF selftests (./benchs/run_bench_ringbufs.sh)
before/after the fix and while it seems a bit slower on some benchmarks, it
is still not significantly enough to matter.

ANDROID: GKI: remove export of tracing control functions
Android GKI kernel modules should NOT have the ability to control the system-wide tracing functionality, nor query to determine if it is on or not. So remove the exports of these functions. Upstream does not wish to do this, so an Android-only change is required. See the bug id for details.

bpf: Allow reads from uninit stack
commit 6715df8d5d24655b9fd368e904028112b54c7de1 upstream.
This commits updates the following functions to allow reads from
uninitialized stack locations when env->allow_uninit_stack option is
enabled:
- check_stack_read_fixed_off()
- check_stack_range_initialized(), called from:
- check_stack_read_var_off()
- check_helper_mem_access()
Such change allows to relax logic in stacksafe() to treat STACK_MISC
and STACK_INVALID in a same way and make the following stack slot
configurations equivalent:
| Cached state | Current state |
| stack slot | stack slot |
|------------------+------------------|
| STACK_INVALID or | STACK_INVALID or |
| STACK_MISC | STACK_SPILL or |
| | STACK_MISC or |
| | STACK_ZERO or |
| | STACK_DYNPTR |
This leads to significant verification speed gains (see below).
The idea was suggested by Andrii Nakryiko [1] and initial patch was
created by Alexei Starovoitov [2].
Currently the env->allow_uninit_stack is allowed for programs loaded
by users with CAP_PERFMON or CAP_SYS_ADMIN capabilities.
A number of test cases from verifier/*.c were expecting uninitialized
stack access to be an error. These test cases were updated to execute
in unprivileged mode (thus preserving the tests).
The test progs/test_global_func10.c expected "invalid indirect read
from stack" error message because of the access to uninitialized
memory region. This error is no longer possible in privileged mode.
The test is updated to provoke an error "invalid indirect access to
stack" because of access to invalid stack address (such error is not
verified by progs/test_global_func*.c series of tests).
The following tests had to be removed because these can't be made
unprivileged:
- verifier/sock.c:
- "sk_storage_get(map, skb->sk, &stack_value, 1): partially init
stack_value"
BPF_PROG_TYPE_SCHED_CLS programs are not executed in unprivileged mode.
- verifier/var_off.c:
- "indirect variable-offset stack access, max_off+size > max_initialized"
- "indirect variable-offset stack access, uninitialized"
These tests verify that access to uninitialized stack values is
detected when stack offset is not a constant. However, variable
stack access is prohibited in unprivileged mode, thus these tests
are no longer valid.

-------------------------- -------------------------- ---------- ---------- ----------------
Note: I limited selection by states_pct<-30%.
Inspection of differences in pyperf600_bpf_loop behavior shows that
the following patch for the test removes almost all differences:
- a/tools/testing/selftests/bpf/progs/pyperf.h
+ b/tools/testing/selftests/bpf/progs/pyperf.h
@ -266,8 +266,8 @ int __on_event(struct bpf_raw_tracepoint_args *ctx)
}
if (event->pthread_match || !pidData->use_tls) {
- void* frame_ptr;
- FrameData frame;
+ void* frame_ptr = 0;
+ FrameData frame = {};
Symbol sym = {};
int cur_cpu = bpf_get_smp_processor_id();
W/o this patch the difference comes from the following pattern
(for different variables):
static bool get_frame_data(... FrameData *frame ...)
{
...
bpf_probe_read_user(&frame->f_code, ...);
if (!frame->f_code)
return false;
...
bpf_probe_read_user(&frame->co_name, ...);
if (frame->co_name)
...;
}
int __on_event(struct bpf_raw_tracepoint_args *ctx)
{
FrameData frame;
...
get_frame_data(... &frame ...) // indirectly via a bpf_loop & callback
...
}
SEC("raw_tracepoint/kfree_skb")
int on_event(struct bpf_raw_tracepoint_args* ctx)
{
...
ret |= __on_event(ctx);
ret |= __on_event(ctx);
...
}
With regards to value `frame->co_name` the following is important:
- Because of the conditional `if (!frame->f_code)` each call to
__on_event() produces two states, one with `frame->co_name` marked
as STACK_MISC, another with it as is (and marked STACK_INVALID on a
first call).
- The call to bpf_probe_read_user() does not mark stack slots
corresponding to `&frame->co_name` as REG_LIVE_WRITTEN but it marks
these slots as BPF_MISC, this happens because of the following loop
in the check_helper_call():
for (i = 0; i < meta.access_size; i++) {
err = check_mem_access(env, insn_idx, meta.regno, i, BPF_B,
BPF_WRITE, -1, false);
if (err)
return err;
}
Note the size of the write, it is a one byte write for each byte
touched by a helper. The BPF_B write does not lead to write marks
for the target stack slot.
- Which means that w/o this patch when second __on_event() call is
verified `if (frame->co_name)` will propagate read marks first to a
stack slot with STACK_MISC marks and second to a stack slot with
STACK_INVALID marks and these states would be considered different.

mm: optimize the redundant loop of mm_update_owner_next()
commit cf3f9a593dab87a032d2b6a6fb205e7f3de4f0a1 upstream. When mm_update_owner_next() is racing with swapoff (try_to_unuse()) or /proc or ptrace or page migration (get_task_mm()), it is impossible to find an appropriate task_struct in the loop whose mm_struct is the same as the target mm_struct. If the above race condition is combined with the stress-ng-zombie and stress-ng-dup tests, such a long loop can easily cause a Hard Lockup in write_lock_irq() for tasklist_lock. Recognize this situation in advance and exit early.

syscalls: fix compat_sys_io_pgetevents_time64 usage
commit d3882564a77c21eb746ba5364f3fa89b88de3d61 upstream.
Using sys_io_pgetevents() as the entry point for compat mode tasks
works almost correctly, but misses the sign extension for the min_nr
and nr arguments.
This was addressed on parisc by switching to
compat_sys_io_pgetevents_time64() in commit 6431e92fc827 ("parisc:
io_pgetevents_time64() needs compat syscall in 32-bit compat mode"),
as well as by using more sophisticated system call wrappers on x86 and
s390. However, arm64, mips, powerpc, sparc and riscv still have the
same bug.
Change all of them over to use compat_sys_io_pgetevents_time64()
like parisc already does. This was clearly the intention when the
function was originally added, but it got hooked up incorrectly in
the tables.

perf/core: Fix missing wakeup when waiting for context reference
[ Upstream commit 74751ef5c1912ebd3e65c3b65f45587e05ce5d36 ]

blocked for more than 18 hours. Their call traces are like this:

[346278.191102] entry_SYSCALL_64_after_hwframe+0x44/0xae
The task was waiting for the refcount become to 1, but from the vmcore,
we found the refcount has already been 1. It seems that the task didn't
get woken up by perf_event_release_kernel() and got stuck forever. The
below scenario may cause the problem.
Thread A Thread B
... ...
perf_event_free_task perf_event_release_kernel
...
acquire event->child_mutex
...
get_ctx
... release event->child_mutex
acquire ctx->mutex
...
perf_free_event (acquire/release event->child_mutex)
...
release ctx->mutex
wait_var_event
acquire ctx->mutex
acquire event->child_mutex
# move existing events to free_list
release event->child_mutex
release ctx->mutex
put_ctx
... ...
In this case, all events of the ctx have been freed, so we couldn't
find the ctx in free_list and Thread A will miss the wakeup. It's thus
necessary to add a wakeup after dropping the reference.

kheaders: explicitly define file modes for archived headers
[ Upstream commit 3bd27a847a3a4827a948387cc8f0dbc9fa5931d5 ] Build environments might be running with different umask settings resulting in indeterministic file modes for the files contained in kheaders.tar.xz. The file itself is served with 444, i.e. world readable. Archive the files explicitly with 744,a+X to improve reproducibility across build environments. --mode=0444 is not suitable as directories need to be executable. Also, 444 makes it hard to delete all the readonly files after extraction.

kcov: don't lose track of remote references during softirqs
commit 01c8f9806bde438ca1c8cbbc439f0a14a6694f6c upstream.
In kcov_remote_start()/kcov_remote_stop(), we swap the previous KCOV
metadata of the current task into a per-CPU variable. However, the
kcov_mode_enabled(mode) check is not sufficient in the case of remote KCOV
coverage: current->kcov_mode always remains KCOV_MODE_DISABLED for remote
KCOV objects.
If the original task that has invoked the KCOV_REMOTE_ENABLE ioctl happens
to get interrupted and kcov_remote_start() is called, it ultimately leads
to kcov_remote_stop() NOT restoring the original KCOV reference. So when
the task exits, all registered remote KCOV handles remain active forever.
The most uncomfortable effect (at least for syzkaller) is that the bug
prevents the reuse of the same /sys/kernel/debug/kcov descriptor. If
we obtain it in the parent process and then e.g. drop some
capabilities and continuously fork to execute individual programs, at
some point current->kcov of the forked process is lost,
kcov_task_exit() takes no action, and all KCOV_REMOTE_ENABLE ioctls
calls from subsequent forks fail.
And, yes, the efficiency is also affected if we keep on losing remote
kcov objects.
a) kcov_remote_map keeps on growing forever.
b) (If I'm not mistaken), we're also not freeing the memory referenced
by kcov->area.
Fix it by introducing a special kcov_mode that is assigned to the task
that owns a KCOV remote object. It makes kcov_mode_enabled() return true
and yet does not trigger coverage collection in __sanitizer_cov_trace_pc()
and write_comp_data().

tracing: Build event generation tests only as modules
[ Upstream commit 3572bd5689b0812b161b40279e39ca5b66d73e88 ] The kprobes and synth event generation test modules add events and lock (get a reference) those event file reference in module init function, and unlock and delete it in module exit function.

zap_pid_ns_processes: clear TIF_NOTIFY_SIGNAL along with TIF_SIGPENDING
[ Upstream commit 7fea700e04bd3f424c2d836e98425782f97b494e ] kernel_wait4() doesn't sleep and returns -EINTR if there is no eligible child and signal_pending() is true. That is why zap_pid_ns_processes() clears TIF_SIGPENDING but this is not enough, it should also clear TIF_NOTIFY_SIGNAL to make signal_pending() return false and avoid a busy-wait loop.

tick/nohz_full: Don't abuse smp_call_function_single() in tick_setup_device()
commit 07c54cc5988f19c9642fd463c2dbdac7fc52f777 upstream.
After the recent commit 5097cbcb38e6 ("sched/isolation: Prevent boot crash
when the boot CPU is nohz_full") the kernel no longer crashes, but there is
another problem.
In this case tick_setup_device() calls tick_take_do_timer_from_boot() to
update tick_do_timer_cpu and this triggers the WARN_ON_ONCE(irqs_disabled)
in smp_call_function_single().
Kill tick_take_do_timer_from_boot() and just use WRITE_ONCE(), the new
comment explains why this is safe (thanks Thomas!).

fsnotify: make allow_dups a property of the group
[ Upstream commit f3010343d9e119da35ee864b3a28993bb5c78ed7 ] Instead of passing the allow_dups argument to fsnotify_add_mark() as an argument, define the group flag FSNOTIFY_GROUP_DUPS to express the allow_dups behavior and set this behavior at group creation time for all calls of fsnotify_add_mark().

exit: Implement kthread_exit
[ Upstream commit bbda86e988d4c124e4cfa816291cbd583ae8bfb1 ]
The way the per task_struct exit_code is used by kernel threads is not
quite compatible how it is used by userspace applications. The low
byte of the userspace exit_code value encodes the exit signal. While
kthreads just use the value as an int holding ordinary kernel function
exit status like -EPERM.
Add kthread_exit to clearly separate the two kinds of uses.

negavite after mkdir/create.
Remove the WARN_ON(!inode) in audit code that were added by the Fixes

kernel/pid.c: implement additional checks upon pidfd_create() parameters
[ Upstream commit 490b9ba881e2c6337bb09b68010803ae98e59f4a ] By adding the pidfd_create() declaration to linux/pid.h, we effectively expose this function to the rest of the kernel. In order to avoid any unintended behavior, or set false expectations upon this function, ensure that constraints are forced upon each of the passed parameters. This includes the checking of whether the passed struct pid is a thread-group leader as pidfd creation is currently limited to such pid types.

kernel/pid.c: remove static qualifier from pidfd_create()
[ Upstream commit c576e0fcd6188d0edb50b0fb83f853433ef4819b ] With the idea of returning pidfds from the fanotify API, we need to expose a mechanism for creating pidfds. We drop the static qualifier from pidfd_create() and add its declaration to linux/pid.h so that the pidfd_create() helper can be called from other kernel subsystems i.e. fanotify. Link: https://lore.kernel.org/r/0c68653ec32f1b7143301f0231f7ed14062fd82b.1628398044.git.repnop@google.com Signed-off-by: Matthew Bobrowski <repnop@google.com> Acked-by: Christian Brauner <christian.brauner@ubuntu.com> Signed-off-by: Jan Kara <jack@suse.cz> Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: Sasha Levin <sashal@kernel.org> |

fanotify: configurable limits via sysfs
[ Upstream commit 5b8fea65d197f408bb00b251c70d842826d6b70b ] fanotify has some hardcoded limits. The only APIs to escape those limits are FAN_UNLIMITED_QUEUE and FAN_UNLIMITED_MARKS. Allow finer grained tuning of the system limits via sysfs tunables under /proc/sys/fs/fanotify, similar to tunables under /proc/sys/fs/inotify, with some minor differences. - max_queued_events - global system tunable for group queue size limit. Like the inotify tunable with the same name, it defaults to 16384 and applies on initialization of a new group. - max_user_marks - user ns tunable for marks limit per user. Like the inotify tunable named max_user_watches, on a machine with sufficient RAM and it defaults to 1048576 in init userns and can be further limited per containing user ns. - max_user_groups - user ns tunable for number of groups per user. Like the inotify tunable named max_user_instances, it defaults to 128 in init userns and can be further limited per containing user ns. The slightly different tunable names used for fanotify are derived from the "group" and "mark" terminology used in the fanotify man pages and throughout the code. Considering the fact that the default value for max_user_instances was increased in kernel v5.10 from 8192 to 1048576, leaving the legacy fanotify limit of 8192 marks per group in addition to the max_user_marks limit makes little sense, so the per group marks limit has been removed. Note that when a group is initialized with FAN_UNLIMITED_MARKS, its own marks are not accounted in the per user marks account, so in effect the limit of max_user_marks is only for the collection of groups that are not initialized with FAN_UNLIMITED_MARKS.

fs: add file and path permissions helpers
[ Upstream commit 02f92b3868a1b34ab98464e76b0e4e060474ba10 ] Add two simple helpers to check permissions on a file and path respectively and convert over some callers. It simplifies quite a few codepaths and also reduces the churn in later patches quite a bit. Christoph also correctly points out that this makes codepaths (e.g. ioctls) way easier to follow that would otherwise have to do more complex argument passing than necessary.

kallsyms: refactor {,module_}kallsyms_on_each_symbol
[ Upstream commit 013c1667cf78c1d847152f7116436d82dcab3db4 ] Require an explicit call to module_kallsyms_on_each_symbol to look for symbols in modules instead of the call from kallsyms_on_each_symbol, and acquire module_mutex inside of module_kallsyms_on_each_symbol instead of leaving that up to the caller. Note that this slightly changes the behavior for the livepatch code in that the symbols from vmlinux are not iterated anymore if objname is set, but that actually is the desired behavior in this case.

kcmp: In get_file_raw_ptr use task_lookup_fd_rcu
[ Upstream commit ed77e80e14a3cd55c73848b9e8043020e717ce12 ] Modify get_file_raw_ptr to use task_lookup_fd_rcu. The helper task_lookup_fd_rcu does the work of taking the task lock and verifying that task->files != NULL and then calls files_lookup_fd_rcu. So let use the helper to make a simpler implementation of get_file_raw_ptr.

file: Replace fcheck_files with files_lookup_fd_rcu
[ Upstream commit f36c2943274199cb8aef32ac96531ffb7c4b43d0 ] This change renames fcheck_files to files_lookup_fd_rcu. All of the remaining callers take the rcu_read_lock before calling this function so the _rcu suffix is appropriate. This change also tightens up the debug check to verify that all callers hold the rcu_read_lock. All callers that used to call files_check with the files->file_lock held have now been changed to call files_lookup_fd_locked. This change of name has helped remind me of which locks and which guarantees are in place helping me to catch bugs later in the patchset. The need for better names became apparent in the last round of discussion of this set of changes[1].

bpf: In bpf_task_fd_query use fget_task
[ Upstream commit b48845af0152d790a54b8ab78cc2b7c07485fc98 ] Use the helper fget_task to simplify bpf_task_fd_query. As well as simplifying the code this removes one unnecessary increment of struct files_struct. This unnecessary increment of files_struct.count can result in exec unnecessarily unsharing files_struct and breaking posix locks, and it can result in fget_light having to fallback to fget reducing performance. This simplification comes from the observation that none of the callers of get_files_struct actually need to call get_files_struct that was made when discussing[1] exec and posix file locks.

kdb: Use format-specifiers rather than memset() for padding in kdb_read()
commit c9b51ddb66b1d96e4d364c088da0f1dfb004c574 upstream. Currently when the current line should be removed from the display kdb_read() uses memset() to fill a temporary buffer with spaces. The problem is not that this could be trivially implemented using a format string rather than open coding it. The real problem is that it is possible, on systems with a long kdb_prompt_str, to write past the end of the tmpbuffer. Happily, as mentioned above, this can be trivially implemented using a format string. Make it so!
