2021-10-02hwmon: (pmbus/ibm-cffps) max_power_out swap changesBrandon Wyman
The bytes for max_power_out from the ibm-cffps devices differ in byte order for some power supplies. The Witherspoon power supply returns the bytes in MSB/LSB order. The Rainier power supply returns the bytes in LSB/MSB order. The Witherspoon power supply uses version cffps1. The Rainier power supply should use version cffps2. If version is cffps1, swap the bytes before output to max_power_out. Tested: Witherspoon before: 3148. Witherspoon after: 3148. Rainier before: 53255. Rainier after: 2000.

This reverts commit 6decd1aad15f56b169217789630a0098b496de0e. CPULAUNCH register is not set properly by some bootloaders, causing a regression until a bootloader change is made, which is hard if not impossible on some embedded devices. Revert the change until a more robust core detection mechanism that works on MT7621S routers such as Netgear R6220 as well as platforms like Digi EX15 can be made.

2021-10-02spi: spi-nxp-fspi: don't depend on a specific node name erratum workaroundMichael Walle
In commit 7e71b85473f8 ("arm64: dts: ls1028a: fix node name for the sysclk") the sysclk node name was renamed and broke the erratum workaround because it tries to fetch a device tree node by its name, which is very fragile in general. We don't even need the sysclk node because the only possible sysclk frequency input is 100MHz. In fact, the erratum says it applies if SYS_PLL_RAT is 3, not that the platform clock is 300 MHz. Make the workaround more reliable and just drop the unneeded sysclk lookup. For reference, the error during the bootup is the following: [ 4.898400] nxp-fspi 20c0000.spi: Errata cannot be executed.

2021-10-01dt-bindings: Drop more redundant 'maxItems/minItems'Rob Herring
Another round of removing redundant minItems/maxItems from new schema in the recent merge window. If a property has an 'items' list, then a 'minItems' or 'maxItems' with the same size as the list is redundant and can be dropped.

2021-10-01net: stmmac: dwmac-rk: Fix ethernet on rk3399 based devicesPunit Agrawal
Commit 2d26f6e39afb ("net: stmmac: dwmac-rk: fix unbalanced pm_runtime_enable warnings") while getting rid of a runtime PM warning ended up breaking ethernet on rk3399 based devices. By dropping an extra reference to the device, the commit ends up enabling suspend / resume of the ethernet device - which appears to be broken. While the issue with runtime pm is being investigated, partially revert commit 2d26f6e39afb to restore the network on rk3399.

2021-10-01net: mscc: ocelot: fix VCAP filters remaining active after being deletedVladimir Oltean
When ocelot_flower.c calls ocelot_vcap_filter_add(), the filter has a given filter->id.cookie. This filter is added to the block->rules list. However, when ocelot_flower.c calls ocelot_vcap_block_find_filter_by_id() which passes the cookie as argument, the filter is never found by filter->id.cookie when searching through the block->rules list. This is unsurprising, since the filter->id.cookie is an unsigned long, but the cookie argument provided to ocelot_vcap_block_find_filter_by_id() is a signed int, and the comparison fails.

2021-10-01drm/msm: One sched entity per process per priorityRob Clark
Some userspace apps make assumptions that rendering against multiple contexts within the same process (from the same thread, with appropriate MakeCurrent() calls) provides sufficient synchronization without any external synchronization (ie. glFenceSync()/glWaitSync()). Since a submitqueue maps to a gl/vk context, having multiple sched entities of the same priority only works with implicit sync enabled. To fix this, limit things to a single sched entity per priority level per process. An alternative would be sharing submitqueues between contexts in userspace, but tracking of per-context faults (ie. GL_EXT_robustness) is already done at the submitqueue level, so this is not an option. Signed-off-by: Rob Clark <robdclark@chromium.org>

Problem: What does this do? $ kunit.py run --json Well, it runs all the tests and prints test results out as JSON. And next is $ kunit.py run my-test-suite --json This runs just `my-test-suite` and prints results out as JSON. But what about? $ kunit.py run --json my-test-suite This runs all the tests and stores the json results in a "my-test-suite" file. Why: --json, and now --raw_output are actually string flags. They just have a default value. --json in particular takes the name of an output file. It was intended that you'd do $ kunit.py run --json=my_output_file my-test-suite if you ever wanted to specify the value. Workaround: It doesn't seem like there's a way to make https://docs.python.org/3/library/argparse.html only accept arg values after a '='. I believe that `--json` should "just work" regardless of where it is. So this patch automatically rewrites a bare `--json` to `--json=stdout`. That makes the examples above work the same way. Add a regression test that can catch this for --raw_output.

2021-10-01SUNRPC: fix sign error causing rpcsec_gss dropsJ. Bruce Fields
If sd_max is unsigned, then sd_max - GSS_SEQ_WIN is a very large number whenever sd_max is less than GSS_SEQ_WIN, and the comparison: seq_num <= sd->sd_max - GSS_SEQ_WIN in gss_check_seq_num is pretty much always true, even when that's clearly not what was intended. This was causing pynfs to hang when using krb5, because pynfs uses zero as the initial gss sequence number. That's perfectly legal, but this logic error causes knfsd to drop the rpc in that case. Out-of-order sequence IDs in the first GSS_SEQ_WIN (128) calls will also cause this.

2021-10-01sched/fair: Add ancestors of unthrottled undecayed cfs_rqMichal Koutný
Since commit a7b359fc6a37 ("sched/fair: Correctly insert cfs_rq's to list on unthrottle") we add cfs_rqs with no runnable tasks but not fully decayed into the load (leaf) list. We may ignore adding some ancestors and therefore breaking tmp_alone_branch invariant. This broke LTP test cfs_bandwidth01 and it was partially fixed in commit fdaba61ef8a2 ("sched/fair: Ensure that the CFS parent is added after unthrottling"). I noticed the named test still fails even with the fix (but with low probability, 1 in ~1000 executions of the test). The reason is when bailing out of unthrottle_cfs_rq early, we may miss adding ancestors of the unthrottled cfs_rq, thus, not joining tmp_alone_branch properly. Fix this by adding ancestors if we notice the unthrottled cfs_rq was added to the load list.

2021-10-01perf/core: fix userpage->time_enabled of inactive eventsSong Liu
Users of rdpmc rely on the mmapped user page to calculate accurate time_enabled. Currently, userpage->time_enabled is only updated when the event is added to the pmu. As a result, inactive event (due to counter multiplexing) does not have accurate userpage->time_enabled. This can be reproduced with something like: /* open 20 task perf_event "cycles", to create multiplexing */ fd = perf_event_open(); /* open task perf_event "cycles" */ userpage = mmap(fd); /* use mmap and rdmpc */ while (true) { time_enabled_mmap = xxx; /* use logic in perf_event_mmap_page */ time_enabled_read = read(fd).time_enabled; if (time_enabled_mmap > time_enabled_read) BUG(); } Fix this by updating userpage for inactive events in merge_sched_in.

2021-10-01perf/x86: Reset destroy callback on event init failureAnand K Mistry
perf_init_event tries multiple init callbacks and does not reset the event state between tries. When x86_pmu_event_init runs, it unconditionally sets the destroy callback to hw_perf_event_destroy. On the next init attempt after x86_pmu_event_init, in perf_try_init_event, if the pmu's capabilities includes PERF_PMU_CAP_NO_EXCLUDE, the destroy callback will be run. However, if the next init didn't set the destroy callback, hw_perf_event_destroy will be run (since the callback wasn't reset). Looking at other pmu init functions, the common pattern is to only set the destroy callback on a successful init. Resetting the callback on failure tries to replicate that pattern. This was discovered after commit f11dd0d80555 ("perf/x86/amd/ibs: Extend PERF_PMU_CAP_NO_EXCLUDE to IBS Op") when the second (and only second) run of the perf tool after a reboot results in 0 samples being generated. The extra run of hw_perf_event_destroy results in active_events having an extra decrement on each perf run. The second run has active_events == 0 and every subsequent run has active_events < 0. When active_events == 0, the NMI handler will early-out and not record any samples.

2021-10-01objtool: Teach get_alt_entry() about more relocation typesPeter Zijlstra
Occasionally objtool encounters symbol (as opposed to section) relocations in .altinstructions. Typically they are the alternatives written by elf_add_alternative() as encountered on a noinstr validation run on vmlinux after having already ran objtool on the individual .o files. Basically this is the counterpart of commit 44f6a7c0755d ("objtool: Fix seg fault with Clang non-section symbols"), because when these new assemblers (binutils now also does this) strip the section symbols, elf_add_reloc_to_insn() is forced to emit symbol based relocations. As such, teach get_alt_entry() about different relocation types.

2021-10-01x86/hpet: Use another crystalball to evaluate HPET usabilityThomas Gleixner
On recent Intel systems the HPET stops working when the system reaches PC10 idle state. The approach of adding PCI ids to the early quirks to disable HPET on these systems is a whack a mole game which makes no sense. Check for PC10 instead and force disable HPET if supported. The check is overbroad as it does not take ACPI, intel_idle enablement and command line parameters into account. That's fine as long as there is at least PMTIMER available to calibrate the TSC frequency. The decision can be overruled by adding "hpet=force" on the kernel command line. Remove the related early PCI quirks for affected Ice Cake and Coffin Lake systems as they are not longer required. That should also cover all other systems, i.e. Tiger Rag and newer generations, which are most likely affected by this as well.
