selftests/cgroup: Preserve CPU hotplug write errors
The cpuset partition root state selftest checks several CPU hotplug
transitions. If writing to a CPU online file fails, the helper still
runs pause afterwards and returns the status of pause instead of the
failed write.
This hides the real hotplug failure and can make later checks run
against expectations for a transition that never happened. Move the
write before the bookkeeping and return when it fails, so callers can
observe the hotplug error and the test does not record a CPU as offline
unless the offline operation actually succeeded.
Also change the O* command handler in set_ctrl_state() to use
"eval $COMM $REDIRECT" like all other handlers. The previous version
set COMM but still called write_cpu_online directly, bypassing the
redirect that captures stderr for error reporting.
Changes since v1:
- Use eval $COMM $REDIRECT in the O* handler instead of calling
write_cpu_online directly (Waiman Long)

docs: cgroup-v2: fix stale "io" controller introduction
The introductory paragraph for the IO controller still states that
weight based distribution is "available only if cfq-iosched is in use"
and that "neither scheme is available for blk-mq devices". This text
dates from when the cgroup v2 documentation was first written (2015)
and was correct at the time, but is no longer accurate:
* cfq-iosched was removed in v5.0;
* blk-mq is now the only block I/O path, and both the absolute limit
scheme (io.max via blk-throttle) and the weight based scheme
(io.weight via iocost, or io.bfq.weight under BFQ) work on it;
* latency based protection (iolatency) and I/O priority (ioprio)
controllers have since been added.
The rest of the section already documents io.weight, io.max,
io.cost.{qos,model}, io.latency and io.prio.class correctly, so the
introduction is the only part that contradicts them. Rewrite it to
reflect the current state.

selftests/cgroup: Avoid awk -e in cpuset tests
The cpuset selftests use awk -e to parse cgroup mount points. This works with gawk, but mawk rejects the option. In test_cpuset_prs.sh, this leaves CGROUP2 empty and causes the test to skip as if cgroup v2 were not mounted. The same non-portable invocation exists in the cpuset v1 hotplug test. The scripts only need to pass a single awk program. Use the standard awk invocation without -e so mount point detection works with awk implementations that do not support the gawk extension. Fixes: |

The cgroup-v2 documentation describes memory.pressure and io.pressure as "read-only nested-keyed file", but both files accept trigger writes (cgroup_memory_pressure_write / cgroup_io_pressure_write) and are therefore read-write. cpu.pressure and irq.pressure are already documented as read-write, so this also resolves an internal inconsistency.

selftests/cgroup: Remove redundant cg_enter_current() call in test_core
The test_cgcore_no_internal_process_constraint_on_threads test has two back-to-back cg_enter_current(root) calls in its cleanup path. A single cg_enter_current() call atomically migrates the entire thread group to the target cgroup even for multi-threaded processes, and this test creates no extra threads or child processes that would require a second migration attempt. The second call is a harmless no-op once the process is already in the root cgroup, but it is redundant and inconsistent with the cleanup logic used in all other cgroup core selftest cases. Remove the duplicate call to clean up the code. No functional change is intended.

selftests/cgroup: Add test for cpuset affinity on controller disable
Add a new selftest that exposes a bug in cpuset_attach() where thread
CPU affinity is not properly updated when the cpuset controller is
disabled in a threaded cgroup hierarchy.
The test creates a threaded cgroup hierarchy with two child cgroups
(A and B) having different cpuset.cpus constraints:
- Parent: cpuset.cpus=0-1
- Child A: cpuset.cpus=0-1
- Child B: cpuset.cpus=1 (restricted to CPU 1 only)
A multithreaded process is created with threads placed in different
cgroups. When the cpuset controller is disabled on the parent, thread
affinities should be updated to match the parent's cpuset.
Expected behavior:
- thread_a affinity: {0-1} before and after (unchanged)
- thread_b affinity: {1} before, {0-1} after (expanded)
Current buggy behavior:
- thread_b affinity remains {1} after controller disable

cgroup/cpuset: Handle the special case of non-moving tasks in cpuset_can_attach()
With cgroup v2 migration of a multithreaded process having threads in different cgroups of a threaded subtree, it is possible that cpuset_can_attach() can be called with tasks that are not migrating with respect to cpuset if cpuset controller is not enabled in some of the subtree cgroups. IOW, the old cpuset can be the same as the new one. This can cause problem when we need to track the set of old cpusets and the new cpusets in singly linked lists as a cpuset cannot be in both lists. As reported by Tejun, the following is an example threaded subtree with partial cpuset delegation that can cause this issue to show up. P (+cpuset) |- R (cpuset) <- destination | `- C (no cpuset) -> effective cpuset == R `- W (cpuset) Group leader in R, thread_a in C, thread_b in W; migrate the whole process into R (echo $PID > R/cgroup.procs). thread_a moves C->R: its cgroup changes so compare_css_sets() keeps it in the taskset, but its cpuset css is unchanged (C inherits R's), so task_cs() == cs == R. cpuset is in ss_mask because thread_b (W->R) changed. can_attach() then tags R as a source (thread_a) and the destination (thread_b): Handle this special case by skipping tasks that are not migrating in cpuset_can_attach() and avoid calling cpuset_can_attach_check() in this case. By doing so, the destination cpuset will not be put into source cpuset linked list. As the source cpuset cannot be easily determined in cpuset_attach(), unnecessary work can be performed if a task is not actually migrating. However, no harm will be done except wasting some CPU cycles. If it happens that none of the tasks is migrating, attach_ctx.old_cs will be NULL and task iteration won't be needed.

cgroup/cpuset: Support multiple destination cpusets for cpuset_*attach()
The only case where the cgroup_taskset structure requires task migration to multiple cpusets is when enabling a cpuset controller in cgroup v2 where the newly created child cpusets inherits the same effective CPUs and memory nodes from the parent. In that case, task migration can happen directly with no update to tasks' CPU and memory nodes assignment and no further work needed from the cpuset side except updating nr_deadline_tasks when DL tasks are involved and setting old_mems_allowed in the child cpusets. Do that by tracking all the destination cpusets with a new dst_cs_head singly linked list. The reset_migrate_dl_data() function is integrated into clear_attach_data() so that it can be used for both source and destination cpusets. A warning will be printed if there are multiple destination cpusets but it is not on default hierarchy or when the CPUs or memory nodes change.

cgroup/cpuset: Support multiple source cpusets for cpuset_*attach()
There are 2 possible scenarios where the cgroup_taskset structure passed into the cgroup can_attach() and attach() methods can contain task migration data with multiple source cpusets. - A multithread application with threads in different cpusets is fully migrated into a new cpuset. - Disabling v2 cpuset controller will move all the tasks in child cpusets to the parent cpuset. The current cpuset_can_attach() and cpuset_attach() functions still expect task migration is from one source cpuset to one destination cpuset. Fix that by tracking the set of source (old) cpusets in singly linked lists. The list will be iterated when necessary to properly update internal data. To ensure proper DL tasks accounting, the nr_migrate_dl_tasks in both the source and destination cpusets are decremented/incremented with their values added to nr_deadline_tasks when the migration is successful. The setting of the global attach_ctx.cpus_updated and attach_ctx.mems_updated flags are also moved from cpuset_attach() to cpuset_can_attach() as the correct source cpuset can no longer be determined in cpuset_attach() and cpuset states will not be changed between cpuset_attach() and cpuset_can_attach() with an earlier patch.

cgroup/cpuset: Make attach_ctx.old_cs track task group leader
There are two possible ways that migration of tasks from multiple source cpusets to a target cpuset can happen. Either a multithread application with threads in different cpusets is wholely migrated to a new cpuset or disabling of v2 cpuset controller will move all the tasks in child cpusets to the parent cpuset. In the former case, it is the mm setting of the group leader that really matters. So attach_ctx.old_cs should track the oldcs of the thread leader. In the latter case, effective_mems of child cpusets must always be a subset of the parent. So no real page migration will not be necessary no matter which child cpuset is selected as attach_ctx.old_cs. IOW, attach_ctx.old_cs should be updated to match the latest task group leader in cpuset_can_attach(), but fall back to that of the first task if there is no group leader in the taskset.

cgroup/cpuset: Fix node inconsistencies between cpuset_update_tasks_nodemask() and cpuset_attach()
Whenever memory node mask is changed, there are 4 places where the node
mask has to be updated or used.
1) task's node mask via cpuset_change_task_nodemask()
2) memory policy binding via mpol_rebind_mm()
3) if memory migration is enabled, migrate from old_mems_allowed to
the new node mask via cpuset_migrate_mm().
4) setting old_mems_allowed
These memory actions are done in cpuset_update_tasks_nodemask() and
cpuset_attach(). However there are inconsistencies in what node masks
are being used in these 2 functions.
In cpuset_update_tasks_nodemask(),
- cpuset_change_task_nodemask(): guarantee_online_mems()
- mpol_rebind_mm(): mems_allowed
- cpuset_migrate_mm(): guarantee_online_mems()
- old_mems_allowed: guarantee_online_mems()
In cpuset_attach(),
- cpuset_change_task_nodemask(): guarantee_online_mems()
- mpol_rebind_mm(): effective_mems
- cpuset_migrate_mm(): effective_mems
- old_mems_allowed: effective_mems
These inconsistencies dates back to quite a long time ago and it is
hard to say what should be the correct values.
The guarantee_online_mems() function returns a node mask from current or
an ancestor cpuset that is a subset of node_states[N_MEMORY]. Nodes in
node_states[N_MEMORY] are all online, i.e. in node_states[N_ONLINE].
However, node in node_states[N_ONLINE] may not have memory. So
node_states[N_MEMORY] should be a subset of node_states[N_ONLINE].
The guarantee_online_mems() function should mostly be useful for v1
where mems_allowed is the same as effective_mems. With v2, the memory
nodes in effective_mems should be a subset of node_states[N_MEMORY]
except when a memory hot-unplug operation is in progress and a memory
node is removed from node_states[N_MEMORY] but not yet reflected in
the effective_mems's as cpuset_handle_hotplug() has not been called
from cpuset_track_online_nodes().
Let use the following setup for both of them and make them consistent.
- cpuset_change_task_nodemask(): guarantee_online_mems()
- mpol_rebind_mm(): effective_mems
- cpuset_migrate_mm(): guarantee_online_mems()
- old_mems_allowed: guarantee_online_mems()
So for v2, it is effectively all effective_mems most of the time. For
v1, mpol_rebind_mm() uses mems_allowed which may differ from what
guarantee_online_mems() returns, but it conforms to what the cpuset v1
documentation says with respect to setting memory policy.

Unlike cpu.stat's throttled_usec which only accounts for throttling caused by the cgroup's own CFS bandwidth limit. When the controller is not enabled, the stat is not reported. Also clarify cpu.stat descriptions: note that the three base CPU usage stats (usage_usec, user_usec, system_usec) include descendant cgroups, and that the five CFS bandwidth stats are non-hierarchical -- they only account for throttling caused by the cgroup's own bandwidth limit.

cgroup: Use data_race() for task->flags in task_css_set_check()
task_css_set_check() uses rcu_dereference_check() to verify that task->cgroups can be dereferenced. One accepted condition is that the task is already exiting, tested by checking PF_EXITING in task->flags. This check is only part of the CONFIG_PROVE_RCU lockdep predicate. This was found by KCSAN during fuzz testing. KCSAN can report a data race when another task flag bit is updated concurrently. One report shows pids_release() reading task->flags through task_css_set_check() while do_task_dead() sets PF_NOFREEZE: KCSAN: data-race in task_css() [inline] KCSAN: data-race in pids_release() task_css() pids_release() cgroup_release() release_task() wait_task_zombie() value changed: 0x0040004c -> 0x0040804c The changed bit is PF_NOFREEZE, not PF_EXITING. PF_EXITING remains set before and after the update, so the task_css_set_check() condition does not change. This is not a race on task->cgroups and does not indicate incorrect pids charging or uncharging. tools/memory-model/Documentation/access-marking.txt recommends data_race() for data-racy loads used only for diagnostic purposes. Use data_race() here to mark the intended diagnostic-only access. No functional change intended.

f2fs-for-7.2-rc1
In this round, the changes primarily focus on filesystem error reporting, reducing memory footprint by reverting in-memory data structures used for runtime validation, honoring FDP hints, and adding trace and debug logs. In addition, there are critical bug fixes resolving out-of-bounds read vulnerabilities in inline directory and ACL handling, potential deadlocks in balance_fs, use-after-free issues in atomic writes, and false data/node type assignments in large sections. Enhancement: - Revert in-memory sit version and block bitmaps - support to report fserror - add trace_f2fs_fault_report - add iostat latency tracking for direct IO - add logs in f2fs_disable_checkpoint() - honor per-I/O write streams for direct writes - map data writes to FDP streams - skip inode folio lookup for cached overwrite - skip direct I/O iostat context when disabled - revert "check in-memory block bitmap" - revert "check in-memory sit version bitmap" Bug fix: - optimize representative type determination in GC - fix incorrect FI_NO_EXTENT handling in __destroy_extent_node() - fix potential deadlock in f2fs_balance_fs() - fix potential deadlock in gc_merge path of f2fs_balance_fs() - atomic: fix UAF issue on f2fs_inode_info.atomic_inode - fix missing read bio submission on large folio error - pass correct iostat type for single node writes - fix to do sanity check on f2fs_get_node_folio_ra() - validate orphan inode entry count - keep atomic write retry from zeroing original data - read COW data with the original inode during atomic write - validate inline dentry name lengths before conversion - validate dentry name length before lookup compares it - reject setattr size changes on large folio files - revert "remove non-uptodate folio from the page cache in move_data_block" - validate ACL entry sizes in f2fs_acl_from_disk() - bound i_inline_xattr_size for non-inline-xattr inodes - fix listxattr handling of corrupted xattr entries - fix to round down start offset of fallocate for pin file -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEE00UqedjCtOrGVvQiQBSofoJIUNIFAmo5sQwACgkQQBSofoJI UNIB7g/+IMAr2UVWdpZ88Uho58GvkkIuZceoZoPuSfUi1hTy0o4+wxeo2ecO06v6 pDlxivkWXRDpdW1iXbUqcmk2HKEsM3ysWb6jvsFXz+eC4QeWKQJ2uZTyLpEVpW2j phXv3TwENPEkku2Mncv907hqUZG/SBxJ2H7jcxb0jHRoaLUwZHuGF0VU/MEodyuy ZJifGI3BMwm7Gu2GXwuliDBjbUHRaBs+8kYQ21NZGv0FuQsCNQ+bLhWz3q4FVfg6 nt5FStKgfoKPHIhamltP6uc4E4KlNDtFgKxluEfzrVqxqvHvUpBxj718DtZLbpNN zD6PUHCI0MU0L7qW+RVJx8TOaceYB5xHVcNi8d+CDQPCJgG0LV0ilykqzQ4LRSob JcPIjEVkrIgNSzYh/PcDHkUBZmt3MiZZf6xaxviqxDoPqyY6TFATF27ZIZbc7jSa hF4XO6mNtbDLhSIMrFUXBnGfnKvIK42OyM5aFLEMxBm7akYYr64h+r6mR+apjDb1 4FQ1YIuKfIHm7DuphUiazmyOV7P4kcOGYbqyiOk/HNxf6Cc3/kOXKTRZq00ORNbX X0FXUOy94xrrjdqoWTldv2o4I49zf8RAEBNLAxDneV2qXsITQtsHWUXp5BbKdA0Q 7nyUBUTOdDvUq3qyXXA9BIKWdTr0XeGGp/z8rrVR0aT6ksqiTzM= =YvkR -----END PGP SIGNATURE----- Merge tag 'f2fs-for-7.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs Pull f2fs updates from Jaegeuk Kim: "The changes primarily focus on filesystem error reporting, reducing memory footprint by reverting in-memory data structures used for runtime validation, honoring FDP hints, and adding trace and debug logs.

perf tools changes for v7.2:
- Introduce 'perf inject --aslr' to remap ASLR-randomized addresses in perf.data files, enabling reproducible analysis across runs with different address space layouts. - Refactor evsel out of sample processing paths: store evsel in struct perf_sample and remove the redundant evsel parameter from tool APIs, tracepoint handlers, hist entry iterators, and db-export, simplifying the entire tool callback chain. - Switch architecture detection from string-based perf_env__arch() comparisons to the numeric ELF e_machine field across the codebase (capstone, print_insn, c2c, lock-contention, sort, sample-raw, machine, header), making cross-analysis more robust. - Overhaul ARM CoreSight ETM tests: add deterministic and named_threads workloads, speed up basic and disassembly tests, add process attribution and concurrent threads tests, remove unused workloads and duplicate tests, queue context packets for the frontend decoder. - Add ARM SPE IMPDEF event decoding for Arm Neoverse N1, store MIDR in arm_spe_pkt for per-CPU event mapping, handle missing CPU IDs gracefully. - Refactor libunwind support: remove the libunwind-local backend, make register reading cross-platform, add RISC-V libunwind support, allow dynamic selection between libdw and libunwind unwinding at runtime. - Extensive hardening of perf.data parsing against crafted files: add bounds checks and byte-swap validation for session records, feature sections, header attributes, BPF metadata, auxtrace errors, compressed events, CPU maps, build ID notes, and ELF program headers. Add minimum event size validation and file offset diagnostics. - Fix libdw API contract violations across dwarf-aux, libdw, probe-finder, annotate-data, and debuginfo subsystems. Fix callchain parent update in ORDER_CALLER mode, support DWARF line 0 in inline lists, handle multiple address spaces in callchains. - Fix numerous 'perf sched' bugs: thread reference leaks, memory leaks, heap overflows with cross-machine recordings, NULL dereferences, replace BUG_ON assertions with graceful error handling, bounds-check CPU indices, fix SIGCHLD vs pause() races in sched stats. - Overhaul the build system: move BPF skeleton generation out of Makefile.perf into bpf_skel.mak, decouple pmu-events from the prepare target, make beauty generated C code standalone .o files, compile BPF skeletons with -mcpu=v3, fix continuous rebuilds, various cleanups. - Add 'perf test' JUnit XML reporting with -j/--junit option, split monolithic test suites into sub-tests, add summary reporting, refactor parallel poll loop, fix test failures on musl-based systems. - Fix 'perf c2c' memory leaks in hist entry and format list handling, use-after-free in error paths, bounds-check CPU and node IDs. - Fix 'perf bpf' metadata leaks on duplicate insert and alloc failure, bounds-check array offsets, validate event sizes and func_info fields, add NULL checks. - Fix hwmon PMU: off-by-one null termination on sysfs reads, strlcpy buffer overflow in parse_hwmon_filename(), fd 0 check, empty label reads, scnprintf usage. - Fix symbols subsystem: bounds-check ELF and sysfs build ID note iteration, validate p_filesz, fix 32-bit ELF bswap error, fix signed overflow in size checks, bounds-check .gnu_debuglink section. - Fix tools lib api: null termination in filename__read_int/ull(), uninitialized stack data in filename__write_int(), snprintf truncation in mount_overload(). - Replace libbabeltrace with babeltrace2-ctf-writer for CTF conversion in 'perf data'. - Add RISC-V SDT argument parsing for static tracepoints. - Add 'perf trace --show-cpu' option to display CPU id. - Add 'perf bench sched pipe --write-size' option. - Add a perf-specific .clang-format that overrides some kernel style behaviors. - Update Intel vendor events for Alder Lake, Arrow Lake, Clearwater Forest, Emerald Rapids, Granite Rapids, Grand Ridge, Lunar Lake, Meteor Lake, Panther Lake, Sapphire Rapids, Sierra Forest. - Add IOMMU metrics for AMD and Intel. - Fix AMD event: switch l2_itlb_misses to bp_l1_tlb_miss_l2_tlb_miss.all. - Add AMD IBS improvements: decode Streaming-store and Remote-Socket flags, suppress bogus fields on Zen4+, skip privilege test on Zen6+. - Fix 'perf lock contention' SIGCHLD vs pause() race, allow 'mmap_lock' in -L filter, enable end-timestamp for cgroup aggregation, fix non-atomic data updates. - Fix 'perf stat' false NMI watchdog warning in aggregation modes, bounds-check CPU index in topology callbacks, add aggr_nr metric parser support for uncore scaling. - Fix 'perf timechart' memory leaks, CPU bounds checking, use-after-free on corrupted callchains. - Fix 'perf inject' itrace branch stack synthesis, fix synthesized sample size with branch stacks. - Fix DSO heap overflow on decompressed paths, uninitialized pathname on fallback, set proper error codes. - Fix various snprintf/scnprintf usages to prevent buffer overflows and truncation across the codebase. - Fix off-by-one stack buffer overflow in kallsyms__parse(). - Fix 'perf kwork' memory management, address sanitizer issues, bounds check work->cpu. - Fix 'perf tpebs' concurrent stop races and PID reuse hazards. - Add O_CLOEXEC to open() calls and use mkostemp() for temporary files to prevent file descriptor leaks to child processes. - Fix s390 Python extension TEXTREL by compiling as PIC. - Fix build with ASAN for jitdump. - Fix build failure due to btf_vlen() return type change.
