2022-04-04dt-bindings: Fix incomplete if/then/else schemasRob Herring
A recent review highlighted that the json-schema meta-schema allows any combination of if/then/else schema keywords even though if, then or else by themselves makes little sense. With an added meta-schema to only allow valid combinations, there's a handful of schemas found which need fixing in a variety of ways. Incorrect indentation is the most common issue.

2022-04-04Revert "ACPI: processor: idle: Only flush cache on entering C3"Akihiko Odaki
Revert commit 87ebbb8c612b ("ACPI: processor: idle: Only flush cache on entering C3") that broke the assumptions of the acpi_idle_play_dead() callers. Namely, the CPU cache must always be flushed in acpi_idle_play_dead(), regardless of the target C-state that is going to be requested, because this is likely to be part of a CPU offline procedure or preparation for entering a system-wide sleep state and the lack of synchronization between the CPU cache and RAM may lead to problems going forward, for example when the CPU is brought back online. In particular, it breaks resume from suspend-to-RAM on Lenovo ThinkPad C13 which fails occasionally until the problematic commit is reverted.

Commit ddbd60c779b4 ("kunit: use --build_dir=.kunit as default") changed the default --build_dir, which had the side effect of making `.kunitconfig` move to `.kunit/.kunitconfig`. However, the first few lines of kunit/start.rst never got updated, oops. Fix this by telling people to run kunit.py first, which will automatically generate the .kunit directory and .kunitconfig file, and then edit the file manually as desired.

2022-04-04IB/rdmavt: add lock to call to rvt_error_qp to prevent a race conditionNiels Dossche
The documentation of the function rvt_error_qp says both r_lock and s_lock need to be held when calling that function. It also asserts using lockdep that both of those locks are held. However, the commit I referenced in Fixes accidentally makes the call to rvt_error_qp in rvt_ruc_loopback no longer covered by r_lock. This results in the lockdep assertion failing and also possibly in a race condition.

2022-04-04x86/mm/tlb: Revert retpoline avoidance approachDave Hansen
0day reported a regression on a microbenchmark which is intended to stress the TLB flushing path: https://lore.kernel.org/all/20220317090415.GE735@xsang-OptiPlex-9020/ It pointed at a commit from Nadav which intended to remove retpoline overhead in the TLB flushing path by taking the 'cond'-ition in on_each_cpu_cond_mask(), pre-calculating it, and incorporating it into 'cpumask'. That allowed the code to use a bunch of earlier direct calls instead of later indirect calls that need a retpoline. But, in practice, threads can go idle (and into lazy TLB mode where they don't need to flush their TLB) between the early and late calls. It works in this direction and not in the other because TLB-flushing threads tend to hold mmap_lock for write. Contention on that lock causes threads to _go_ idle right in this early/late window. There was not any performance data in the original commit specific to the retpoline overhead. I did a few tests on a system with retpolines: https://lore.kernel.org/all/dd8be93c-ded6-b962-50d4-96b1c3afb2b7@intel.com/ which showed a possible small win. But, that small win pales in comparison with the bigger loss induced on non-retpoline systems. Revert the patch that removed the retpolines. This was not a clean revert, but it was self-contained enough not to be too painful.

2022-04-04random: do not split fast init input in add_hwgenerator_randomness()Jan Varho
add_hwgenerator_randomness() tries to only use the required amount of input for fast init, but credits all the entropy, rather than a fraction of it. Since it's hard to determine how much entropy is left over out of a non-unformly random sample, either give it all to fast init or credit it, but don't attempt to do both. In the process, we can clean up the injection code to no longer need to return a value.

2022-04-04cifs: remove check of list iterator against head past the loop bodyJakob Koschel
When list_for_each_entry() completes the iteration over the whole list without breaking the loop, the iterator value will be a bogus pointer computed based on the head element. While it is safe to use the pointer to determine if it was computed based on the head element, either with list_entry_is_head() or &pos->member == head, using the iterator variable after the loop should be avoided. In preparation to limit the scope of a list iterator to the list traversal loop, use a dedicated pointer to point to the found element [1].

In __nat25_add_pppoe_tag(), the tag length is read from the tag data structure. The value is kept in network format, but read as raw value. With -Warray-bounds, this results in the following gcc error/warning when building the driver on alpha.

It should be noted, however, that this fix means that the code did probably not work on any little endian systems and/or that the driver has other endiannes related issues. A build with C=1 suggests that this is indeed the case. This patch does not attempt to fix any of those other issues.

2022-04-04IB/cm: Cancel mad on the DREQ event when the state is MRA_REP_RCVDMark Zhang
On the passive side when the disconnectReq event comes, if the current state is MRA_REP_RCVD, it needs to cancel the MAD before entering the DREQ_RCVD and TIMEWAIT states, otherwise the destroy_id may block until this mad will reach timeout.

2022-04-04ASoC: soc-pcm: use GFP_KERNEL when the code is sleepableChristophe JAILLET
At the kzalloc() call in dpcm_be_connect(), there is no spin lock involved. It's merely protected by card->pcm_mutex, instead. The spinlock is applied at the later call with snd_soc_pcm_stream_lock_irq() only for the list manipulations. (See it's *_irq(), not *_irqsave(); that means the context being sleepable at that point.) So, we can use GFP_KERNEL safely there. This patch revert commit d8a9c6e1f676 ("ASoC: soc-pcm: use GFP_ATOMIC for dpcm structure") which is no longer needed since commit b7898396f4bb ("ASoC: soc-pcm: Fix and cleanup DPCM locking").

2022-04-04codecs: rt5682s: fix an incorrect NULL check on list iteratorXiaomeng Tong
The bug is here: if (!dai) { The list iterator value 'dai' will *always* be set and non-NULL by for_each_component_dais(), so it is incorrect to assume that the iterator value will be NULL if the list is empty or no element is found (In fact, it will be a bogus pointer to an invalid struct object containing the HEAD). Otherwise it will bypass the check 'if (!dai) {' (never call dev_err() and never return -ENODEV;) and lead to invalid memory access lately when calling 'rt5682s_set_bclk1_ratio(dai, factor);'.

2022-04-04ASoC: atmel: Remove system clock tree configuration for at91sam9g20ekMark Brown
The MCLK of the WM8731 on the AT91SAM9G20-EK board is connected to the PCK0 output of the SoC, intended in the reference software to be supplied using PLLB and programmed to 12MHz. As originally written for use with a board file the audio driver was responsible for configuring the entire tree but in the conversion to the common clock framework the registration of the named pck0 and pllb clocks was removed so the driver has failed to instantiate ever since. Since the WM8731 driver has had support for managing a MCLK provided via the common clock framework for some time we can simply drop all the clock management code from the machine driver other than configuration of the sysclk rate, the CODEC driver still respects that configuration from the machine driver.

2022-04-04gpio: Restrict usage of GPIO chip irq members before initializationShreeya Patel
GPIO chip irq members are exposed before they could be completely initialized and this leads to race conditions. One such issue was observed for the gc->irq.domain variable which was accessed through the I2C interface in gpiochip_to_irq() before it could be initialized by gpiochip_add_irqchip(). This resulted in Kernel NULL pointer dereference. Following are the logs for reference :- kernel: Call Trace: kernel: gpiod_to_irq+0x53/0x70 kernel: acpi_dev_gpio_irq_get_by+0x113/0x1f0 kernel: i2c_acpi_get_irq+0xc0/0xd0 kernel: i2c_device_probe+0x28a/0x2a0 kernel: really_probe+0xf2/0x460 kernel: RIP: 0010:gpiochip_to_irq+0x47/0xc0 To avoid such scenarios, restrict usage of GPIO chip irq members before they are completely initialized.

Add checks in the XDP redirect callback to prevent XDP from running when the TX ring is undergoing shutdown. Also remove redundant checks in the XDP redirect callback to validate the txr and the flag that indicates the ring supports XDP. The modulo arithmetic on 'tx_nr_rings_xdp' already guarantees the derived TX ring is an XDP ring. txr is also guaranteed to be valid after checking BNXT_STATE_OPEN and within RCU grace period.
