The recommended ways for getting DAMON monitoring results are using tried_regions sysfs directory for partial snapshot of the results, and DAMON tracepoint for full record of the results. However, the tried_regions sysfs directory usage has not sufficiently updated on some sections of the DAMON usage document. Update those.

2023-06-19kasan: add support for kasan.fault=panic_on_writeGravatar Marco Elver 1-3/+4
KASAN's boot time kernel parameter 'kasan.fault=' currently supports 'report' and 'panic', which results in either only reporting bugs or also panicking on reports. However, some users may wish to have more control over when KASAN reports result in a kernel panic: in particular, KASAN reported invalid _writes_ are of special interest, because they have greater potential to corrupt random kernel memory or be more easily exploited. To panic on invalid writes only, introduce 'kasan.fault=panic_on_write', which allows users to choose to continue running on invalid reads, but panic only on invalid writes.

2023-06-19mm/pgtable: allow pte_offset_map[_lock]() to failGravatar Hugh Dickins 1-6/+11
Make pte_offset_map() a wrapper for __pte_offset_map() (optionally outputs pmdval), pte_offset_map_lock() a sparse __cond_lock wrapper for __pte_offset_map_lock(): those __funcs added in mm/pgtable-generic.c. __pte_offset_map() do pmdval validation (including pmd_clear_bad() when pmd_bad()), returning NULL if pmdval is not for a page table. __pte_offset_map_lock() verify pmdval unchanged after getting the lock, trying again if it changed. No #ifdef CONFIG_TRANSPARENT_HUGEPAGE around them: that could be done to cover the imminent case, but we expect to generalize it later, and it makes a mess of where to do the pmd_bad() clearing. Add pte_offset_map_nolock(): outputs ptl like pte_offset_map_lock(), without actually taking the lock. This will be preferred to open uses of pte_lockptr(), because (when split ptlock is in page table's struct page) it points to the right lock for the returned pte pointer, even if *pmd gets changed racily afterwards. Update corresponding Documentation. Do not add the anticipated rcu_read_lock() and rcu_read_unlock()s yet: they have to wait until all architectures are balancing pte_offset_map()s with pte_unmap()s (as in the arch series posted earlier). But comment where they will go, so that it's easy to add them for experiments. And only when those are in place can transient racy failure cases be enabled. Add more safety for the PAE mismatched pmd_low pmd_high case at that time.

2023-06-09mm/memcontrol: export memcg.swap watermark via sysfs for v2 memcgGravatar Lars R. Damerow 1-0/+7
This patch is similar to commit 8e20d4b33266 ("mm/memcontrol: export memcg->watermark via sysfs for v2 memcg"), but exports the swap counter's watermark. We allocate jobs to our compute farm using heuristics determined by memory and swap usage from previous jobs. Tracking the peak swap usage for new jobs is important for determining when jobs are exceeding their expected bounds, or when our baseline metrics are getting outdated. Our toolset was written to use the "memory.memsw.max_usage_in_bytes" file in cgroups v1, and altering it to poll cgroups v2's "memory.swap.current" would give less accurate results as well as add complication to the code. Having this watermark exposed in sysfs is much preferred. Link: https://lkml.kernel.org/r/20230524181734.125696-1-lars@pixar.com Signed-off-by: Lars R.

This keeps the allocation separate from the registration and avoids various races. - Remove RCU locking around pin_user_pages_remote() as that can schedule. The RCU protection is no longer needed with the above split of mm allocation and attaching. - Rename the "link" fields of the various structs to something more meaningful. - Add comments around user_event_mm struct usage and locking requirements. Timerlat tracer: - Fix missed wakeup of timerlat thread caused by the timerlat interrupt triggering when tracing is off. The timer interrupt handler needs to always wake up the timerlat thread regardless if tracing is enabled or not, otherwise, it will never wake up. Histograms: - Fix regression of breaking the "stacktrace" modifier for variables. That modifier cannot be used for values, but can be used for variables that are passed from one histogram to the next. This was broken when adding the restriction to values as the variable logic used the same code. - Rename the special field "stacktrace" to "common_stacktrace". Special fields (that are not actually part of the event, but can act just like event fields, like 'comm' and 'timestamp') should be prefixed with 'common_' for consistency. To keep backward compatibility, 'stacktrace' can still be used (as with the special field 'cpu'), but can be overridden if the event has a field called 'stacktrace'. - Update the synthetic event selftests to use the new name (synthetic events are created by histograms) Tracing bootup selftests: - Reorganize the code to keep artifacts of the selftests not compiled in when selftests are not configured. - Add various cond_resched() around the selftest code, as the softlock watchdog was triggering much more often. It appears that the kernel runs slower now with full debugging enabled. - While debugging ftrace with ftrace (using an instance ring buffer instead of the top level one), I found that the selftests were disabling prints to the debug instance. This should not happen, as the selftests only disable printing to the main buffer as the selftests examine the main buffer to see if it has what it expects, and prints can make the tests fail.

2023-05-23tracing: Rename stacktrace field to common_stacktraceGravatar Steven Rostedt (Google) 1-32/+32
The histogram and synthetic events can use a pseudo event called "stacktrace" that will create a stacktrace at the time of the event and use it just like it was a normal field. We have other pseudo events such as "common_cpu" and "common_timestamp". To stay consistent with that, convert "stacktrace" to "common_stacktrace". As this was used in older kernels, to keep backward compatibility, this will act just like "common_cpu" did with "cpu". That is, "cpu" will be the same as "common_cpu" unless the event has a "cpu" field. In which case, the event's field is used. The same is true with "stacktrace". Also update the documentation to reflect this change.

2023-05-16docs: quickly-build-trimmed-linux: various small fixes and improvementsGravatar Thorsten Leemhuis 1-22/+27
* improve the short description of localmodconfig in the step-by-step guide while fixing its broken first sentence * briefly mention immutable Linux distributions * use '--shallow-exclude=v6.0' throughout the document * instead of "git reset --hard; git checkout ..." use "git checkout --force ..." in the step-by-step guide: this matches the TLDR and is one command less to execute. This led to a few small adjustments to the text and the flow in the surrounding area. * fix two thinkos in the section explaining full git clones Signed-off-by: Thorsten Leemhuis <linux@leemhuis.info> Link: https://lore.kernel.org/r/6f4684b9a5d11d3adb04e0af3cfc60db8b28eeb2.1684140700.git.linux@leemhuis.info Signed-off-by: Jonathan Corbet <corbet@lwn.net>
