2021-02-20fix handling of nd->depth on LOOKUP_CACHED failures in try_to_unlazy*Al Viro1-4/+5
After switching to non-RCU mode, we want nd->depth to match the number of entries in nd->stack[] that need eventual path_put(). legitimize_links() takes care of that on failures; unfortunately, failure exits added for LOOKUP_CACHED do not. We could add the logics for that into those failure exits, both in try_to_unlazy() and in try_to_unlazy_next(), but since both checks are immediately followed by legitimize_links() and there's no calls of legitimize_links() other than those two... It's easier to move the check (and required handling of nd->depth on failure) into legitimize_links() itself. [caught by Jens: ... and since we are zeroing ->depth here, we need to do drop_links() first] Fixes: 6c6ec2b0a3e0 "fs: add support for LOOKUP_CACHED" Tested-by: Jens Axboe <[email protected]> Signed-off-by: Al Viro <[email protected]>
2021-02-19kprobes: Fix to delay the kprobes jump optimizationMasami Hiramatsu1-10/+21
Commit 36dadef23fcc ("kprobes: Init kprobes in early_initcall") moved the kprobe setup in early_initcall(), which includes kprobe jump optimization. The kprobes jump optimizer involves synchronize_rcu_tasks() which depends on the ksoftirqd and rcu_spawn_tasks_*(). However, since those are setup in core_initcall(), kprobes jump optimizer can not run at the early_initcall(). To avoid this issue, make the kprobe optimization disabled in the early_initcall() and enables it in subsys_initcall(). Note that non-optimized kprobes is still available after early_initcall(). Only jump optimization is delayed.

2021-02-18perf test: Output the sub testing result in cs-etmLeo Yan1-10/+14
The CoreSight testing contains sub cases, e.g. every CPU iterates the possible conntected sinks and tests the paths between the associated ETM with the found sink. Besides the per-thread testing, it also contains system wide testing and snapshot testing. To easier observe results for the sub cases, this patch introduces a new function arm_cs_report(), it outputs the result as "PASS" or "FAIL" for every sub case; and it records the error in the variable "glb_err" which is used as the final return value when exits the testing.

And it outputs some trivial info from "perf record" command and there have debugging info for CPU number and device name when iterates between ETMs and sinks. For a neat output format, this patch redirects the output logs to "/dev/null", thus can avoid to flood logs. And it removes the redundant log for CPU number and device name, which have already printed out the relevant info in the function record_touch_file().

At that point, there is a branch from_ip, to_ip with corresponding from_nr and to_nr. In the event of VM-Entry failure, there should still PIP and TIP packets that can be followed in the same way.

The ubsan reported the following error. It was because sample's raw data missed u32 padding at the end. So it broke the alignment of the array after it. The raw data contains an u32 size prefix so the data size should have an u32 padding after 8-byte aligned data. 27: Sample parsing :util/synthetic-events.c:1539:4: runtime error: store to misaligned address 0x62100006b9bc for type '__u64' (aka 'unsigned long long'), which requires 8 byte alignment 0x62100006b9bc: note: pointer points here 00 00 00 00 ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ^ #0 0x561532a9fc96 in perf_event__synthesize_sample util/synthetic-events.c:1539:13 #1 0x5615327f4a4f in do_test tests/sample-parsing.c:284:8 #2 0x5615327f3f50 in test__sample_parsing tests/sample-parsing.c:381:9 #3 0x56153279d3a1 in run_test tests/builtin-test.c:424:9 #4 0x56153279c836 in test_and_print tests/builtin-test.c:454:9 #5 0x56153279b7eb in __cmd_test tests/builtin-test.c:675:4 #6 0x56153279abf0 in cmd_test tests/builtin-test.c:821:9 #7 0x56153264e796 in run_builtin perf.c:312:11 #8 0x56153264cf03 in handle_internal_command perf.c:364:8 #9 0x56153264e47d in run_argv perf.c:408:2 #10 0x56153264c9a9 in main perf.c:538:3 #11 0x7f137ab6fbbc in __libc_start_main (/lib64/libc.so.6+0x38bbc) #12 0x561532596828 in _start ...

2021-02-18perf tools: Support arch specific PERF_SAMPLE_WEIGHT_STRUCT processingKan Liang4-14/+43
For X86, the var2_w field of PERF_SAMPLE_WEIGHT_STRUCT stands for the instruction latency. Current perf forces the var2_w to the data->ins_lat in the generic code. It works well for now because X86 is the only architecture that supports the PERF_SAMPLE_WEIGHT_STRUCT, but it may bring problems once other architectures support the sample type. For example, the var2_w may be used to capture something else on PowerPC. Create two architecture specific functions to parse and synthesize the weight related samples. Move the X86 specific codes to the X86 version functions. Other architectures can implement their own functions later separately.
