Thomas Gleixner	95247d24c4	genirq: Disable interrupts for force threaded handlers ... commit 81e2073c17 upstream. With interrupt force threading all device interrupt handlers are invoked from kernel threads. Contrary to hard interrupt context the invocation only disables bottom halfs, but not interrupts. This was an oversight back then because any code like this will have an issue: thread(irq_A) irq_handler(A) spin_lock(&foo->lock); interrupt(irq_B) irq_handler(B) spin_lock(&foo->lock); This has been triggered with networking (NAPI vs. hrtimers) and console drivers where printk() happens from an interrupt which interrupted the force threaded handler. Now people noticed and started to change the spin_lock() in the handler to spin_lock_irqsave() which affects performance or add IRQF_NOTHREAD to the interrupt request which in turn breaks RT. Fix the root cause and not the symptom and disable interrupts before invoking the force threaded handler which preserves the regular semantics and the usefulness of the interrupt force threading as a general debugging tool. For not RT this is not changing much, except that during the execution of the threaded handler interrupts are delayed until the handler returns. Vs. scheduling and softirq processing there is no difference. For RT kernels there is no issue.

Peter Zijlstra	e5154ea8e4	static_call: Fix static_call_update() sanity check ... commit 38c9358737 upstream. Sites that match init_section_contains() get marked as INIT. For built-in code init_sections contains both __init and __exit text. OTOH kernel_text_address() only explicitly includes __init text (and there are no __exit text markers). Match what jump_label already does and ignore the warning for INIT sites.

Frank van der Linden	d802672c7f	module: harden ELF info handling ... [ Upstream commit ec2a29593c ] 5fdc7db644 ("module: setup load info before module_sig_check()") moved the ELF setup, so that it was done before the signature check. This made the module name available to signature error messages. However, the checks for ELF correctness in setup_load_info are not sufficient to prevent bad memory references due to corrupted offset fields, indices, etc. So, there's a regression in behavior here: a corrupt and unsigned (or badly signed) module, which might previously have been rejected immediately, can now cause an oops/crash. Harden ELF handling for module loading by doing the following: - Move the signature check back up so that it comes before ELF initialization. It's best to do the signature check to see if we can trust the module, before using the ELF structures inside it. This also makes checks against info->len more accurate again, as this field will be reduced by the length of the signature in mod_check_sig(). The module name is now once again not available for error messages during the signature check, but that seems like a fair tradeoff. - Check if sections have offset / size fields that at least don't exceed the length of the module. - Check if sections have section name offsets that don't fall outside the section name table. - Add a few other sanity checks against invalid section indices, etc. This is not an exhaustive consistency check, but the idea is to at least get through the signature and blacklist checks without crashing because of corrupted ELF info, and to error out gracefully for most issues that would have caused problems later on.

Vlastimil Babka	a2bbfa414c	FROMGIT: kernel/power: allow hibernation with page_poison sanity checking ... Page poisoning used to be incompatible with hibernation, as the state of poisoned pages was lost after resume, thus enabling CONFIG_HIBERNATION forces CONFIG_PAGE_POISONING_NO_SANITY. For the same reason, the poisoning with zeroes variant CONFIG_PAGE_POISONING_ZERO used to disable hibernation. The latter restriction was removed by commit 1ad1410f63 ("PM / Hibernate: allow hibernation with PAGE_POISONING_ZERO") and similarly for init_on_free by commit 18451f9f9e ("PM: hibernate: fix crashes with init_on_free=1") by making sure free pages are cleared after resume. We can use the same mechanism to instead poison free pages with PAGE_POISON after resume. This covers both zero and 0xAA patterns. Thus we can remove the Kconfig restriction that disables page poison sanity checking when hibernation is enabled.

Choonghoon Park	f25741f047	ANDROID: sched/fair: Do not sync task util with SD_BALANCE_FORK ... When android_rvh_select_task_rq_fair is enabled, the woken-up new fair task's utilization is always updated in a wakeup path (wake_up_new_task) although it doesn't have to be. It is because sync_entity_load_avg() is always called in select_task_rq_fair() with the hook enabled. Let's see what happened: The new task's sched_avg->last_update_time should be 0 unless it is updated in attach_entity_cfs_rq() in the wakeup path. But because sync_entity_load_avg() is called, sched_avg->last_update_time is updated with cfs_rq->avg.last_update_time before attach_entity_cfs_rq() is called. After updated, post_init_entity_util_avg() is called and the half of spare capacity of rq which the task is assigned to is set to the task's utilization. Finally, update_load_avg() is called and check the task's sched_avg->last_update_time, and update the task's utilization due to non-zero last_update_time. - wake_up_new_task() - select_task_rq() <-- task's sched_avg->last_update_time is set if android_rvh_select_task_rq_fair is enabled. - post_init_entity_util_avg() <-- task gets the half of spare cap. - attach_entity_cfs_rq() - update_load_avg <-- update task's utiliztion because task's sched_avg->last_update_time is not 0. Make sure not to call sync_entity_load_avg() in select_task_rq_fair() when SD_BALANCE_FORK is also set with the hook.

Piotr Krysiuk	1010f17aaa	bpf: Add sanity check for upper ptr_limit ... commit 1b1597e64e upstream. Given we know the max possible value of ptr_limit at the time of retrieving the latter, add basic assertions, so that the verifier can bail out if anything looks odd and reject the program. Nothing triggered this so far, but it also does not hurt to have these.

Piotr Krysiuk	6a3504bf40	bpf: Simplify alu_limit masking for pointer arithmetic ... commit b5871dca25 upstream. Instead of having the mov32 with aux->alu_limit - 1 immediate, move this operation to retrieve_ptr_limit() instead to simplify the logic and to allow for subsequent sanity boundary checks inside retrieve_ptr_limit(). This avoids in future that at the time of the verifier masking rewrite we'd run into an underflow which would not sign extend due to the nature of mov32 instruction.

Piotr Krysiuk	ac1b87a18c	bpf: Fix off-by-one for area size in creating mask to left ... commit 10d2bb2e6b upstream. retrieve_ptr_limit() computes the ptr_limit for registers with stack and map_value type. ptr_limit is the size of the memory area that is still valid / in-bounds from the point of the current position and direction of the operation (add / sub). This size will later be used for masking the operation such that attempting out-of-bounds access in the speculative domain is redirected to remain within the bounds of the current map value. When masking to the right the size is correct, however, when masking to the left, the size is off-by-one which would lead to an incorrect mask and thus incorrect arithmetic operation in the non-speculative domain. Piotr found that if the resulting alu_limit value is zero, then the BPF_MOV32_IMM() from the fixup_bpf_calls() rewrite will end up loading 0xffffffff into AX instead of sign-extending to the full 64 bit range, and as a result, this allows abuse for executing speculatively out-of- bounds loads against 4GB window of address space and thus extracting the contents of kernel memory via side-channel.

Piotr Krysiuk	c4d37eea1c	bpf: Prohibit alu ops for pointer types not defining ptr_limit ... commit f232326f69 upstream. The purpose of this patch is to streamline error propagation and in particular to propagate retrieve_ptr_limit() errors for pointer types that are not defining a ptr_limit such that register-based alu ops against these types can be rejected. The main rationale is that a gap has been identified by Piotr in the existing protection against speculatively out-of-bounds loads, for example, in case of ctx pointers, unprivileged programs can still perform pointer arithmetic. This can be abused to execute speculatively out-of-bounds loads without restrictions and thus extract contents of kernel memory. Fix this by rejecting unprivileged programs that attempt any pointer arithmetic on unprotected pointer types. The two affected ones are pointer to ctx as well as pointer to map. Field access to a modified ctx' pointer is rejected at a later point in time in the verifier, and 7c69673262 ("bpf: Permit map_ptr arithmetic with opcode add and offset 0") only relevant for root-only use cases. Risk of unprivileged program breakage is considered very low.

Anna-Maria Behnsen	df7dbfc24c	hrtimer: Update softirq_expires_next correctly after __hrtimer_get_next_event() ... [ Upstream commit 46eb1701c0 ] hrtimer_force_reprogram() and hrtimer_interrupt() invokes __hrtimer_get_next_event() to find the earliest expiry time of hrtimer bases. __hrtimer_get_next_event() does not update cpu_base::[softirq_]_expires_next to preserve reprogramming logic. That needs to be done at the callsites. hrtimer_force_reprogram() updates cpu_base::softirq_expires_next only when the first expiring timer is a softirq timer and the soft interrupt is not activated. That's wrong because cpu_base::softirq_expires_next is left stale when the first expiring timer of all bases is a timer which expires in hard interrupt context. hrtimer_interrupt() does never update cpu_base::softirq_expires_next which is wrong too. That becomes a problem when clock_settime() sets CLOCK_REALTIME forward and the first soft expiring timer is in the CLOCK_REALTIME_SOFT base. Setting CLOCK_REALTIME forward moves the clock MONOTONIC based expiry time of that timer before the stale cpu_base::softirq_expires_next. cpu_base::softirq_expires_next is cached to make the check for raising the soft interrupt fast. In the above case the soft interrupt won't be raised until clock monotonic reaches the stale cpu_base::softirq_expires_next value. That's incorrect, but what's worse it that if the softirq timer becomes the first expiring timer of all clock bases after the hard expiry timer has been handled the reprogramming of the clockevent from hrtimer_interrupt() will result in an interrupt storm. That happens because the reprogramming does not use cpu_base::softirq_expires_next, it uses __hrtimer_get_next_event() which returns the actual expiry time. Once clock MONOTONIC reaches cpu_base::softirq_expires_next the soft interrupt is raised and the storm subsides. Change the logic in hrtimer_force_reprogram() to evaluate the soft and hard bases seperately, update softirq_expires_next and handle the case when a soft expiring timer is the first of all bases by comparing the expiry times and updating the required cpu base fields. Split this functionality into a separate function to be able to use it in hrtimer_interrupt() as well without copy paste.

Kan Liang	82ad50c112	perf/core: Flush PMU internal buffers for per-CPU events ... [ Upstream commit a5398bffc0 ] Sometimes the PMU internal buffers have to be flushed for per-CPU events during a context switch, e.g., large PEBS. Otherwise, the perf tool may report samples in locations that do not belong to the process where the samples are processed in, because PEBS does not tag samples with PID/TID. The current code only flush the buffers for a per-task event. It doesn't check a per-CPU event. Add a new event state flag, PERF_ATTACH_SCHED_CB, to indicate that the PMU internal buffers have to be flushed for this event during a context switch. Add sched_cb_entry and perf_sched_cb_usages back to track the PMU/cpuctx which is required to be flushed. Only need to invoke the sched_task() for per-CPU events in this patch. The per-task events have been handled in perf_event_context_sched_in/out already.

Sangmoon Kim	f23fe39801	FROMGIT: rcu/tree: Add a trace event for RCU CPU stall warnings ... This commit adds a trace event which allows tracing the beginnings of RCU CPU stall warnings on systems where sysctl_panic_on_rcu_stall is disabled. The first parameter is the name of RCU flavor like other trace events. The second parameter indicates whether this is a stall of an expedited grace period, a self-detected stall of a normal grace period, or a stall of a normal grace period detected by some CPU other than the one that is stalled. RCU CPU stall warnings are often caused by external-to-RCU issues, for example, in interrupt handling or task scheduling. Therefore, this event uses TRACE_EVENT, not TRACE_EVENT_RCU, to avoid requiring those interested in tracing RCU CPU stalls to rebuild their kernels with CONFIG_RCU_TRACE=y.

Steven Rostedt (VMware)	3301afbfef	ring-buffer: Force before_stamp and write_stamp to be different on discard ... commit 6f6be606e7 upstream. Part of the logic of the new time stamp code depends on the before_stamp and the write_stamp to be different if the write_stamp does not match the last event on the buffer, as it will be used to calculate the delta of the next event written on the buffer. The discard logic depends on this, as the next event to come in needs to inject a full timestamp as it can not rely on the last event timestamp in the buffer because it is unknown due to events after it being discarded. But by changing the write_stamp back to the time before it, it forces the next event to use a full time stamp, instead of relying on it. The issue came when a full time stamp was used for the event, and rb_time_delta() returns zero in that case. The update to the write_stamp (which subtracts delta) made it not change. Then when the event is removed from the buffer, because the before_stamp and write_stamp still match, the next event written would calculate its delta from the write_stamp, but that would be wrong as the write_stamp is of the time of the event that was discarded. In the case that the delta change being made to write_stamp is zero, set the before_stamp to zero as well, and this will force the next event to inject a full timestamp and not use the current write_stamp.

Juri Lelli	9a68fa0ebb	sched/features: Fix hrtick reprogramming ... [ Upstream commit 156ec6f42b ] Hung tasks and RCU stall cases were reported on systems which were not 100% busy. Investigation of such unexpected cases (no sign of potential starvation caused by tasks hogging the system) pointed out that the periodic sched tick timer wasn't serviced anymore after a certain point and that caused all machinery that depends on it (timers, RCU, etc.) to stop working as well. This issues was however only reproducible if HRTICK was enabled. Looking at core dumps it was found that the rbtree of the hrtimer base used also for the hrtick was corrupted (i.e. next as seen from the base root and actual leftmost obtained by traversing the tree are different). Same base is also used for periodic tick hrtimer, which might get "lost" if the rbtree gets corrupted. Much alike what described in commit 1f71addd34 ("tick/sched: Do not mess with an enqueued hrtimer") there is a race window between hrtimer_set_expires() in hrtick_start and hrtimer_start_expires() in __hrtick_restart() in which the former might be operating on an already queued hrtick hrtimer, which might lead to corruption of the base. Use hrtick_start() (which removes the timer before enqueuing it back) to ensure hrtick hrtimer reprogramming is entirely guarded by the base lock, so that no race conditions can occur.

Peter Zijlstra	6816509065	sched/core: Allow try_invoke_on_locked_down_task() with irqs disabled ... commit 1b7af29554 upstream. The try_invoke_on_locked_down_task() function currently requires that interrupts be enabled, but it is called with interrupts disabled from rcu_print_task_stall(), resulting in an "IRQs not enabled as expected" diagnostic. This commit therefore updates try_invoke_on_locked_down_task() to use raw_spin_lock_irqsave() instead of raw_spin_lock_irq(), thus allowing use from either context.
