2025-04-24selftests: ublk: common: fix _get_disk_dev_t for pre-9.0 coreutilsUday Shankar
Some distributions, such as centos stream 9, still have a version of coreutils which does not yet support the %Hr and %Lr formats for stat(1) [1, 2]. Running ublk selftests on these distributions results in the following error in tests that use the _get_disk_dev_t helper: line 23: ?r: syntax error: operand expected (error token is "?r") To better accommodate older distributions, rewrite _get_disk_dev_t to use the much older %t and %T formats for stat instead.

2025-04-23selftests: mptcp: diag: use mptcp_lib_get_info_valueGeliang Tang
When running diag.sh in a loop, chk_dump_one will report the following "grep: write error": 13 ....chk 2 cestab [ OK ] grep: write error 14 ....chk dump_one [ OK ] 15 ....chk 2->0 msk in use after flush [ OK ] 16 ....chk 2->0 cestab after flush [ OK ] This error is caused by a broken pipe. When the output of 'ss' is processed by grep, 'head -n 1' will exit immediately after getting the first line, causing the subsequent pipe to close. At this time, if 'grep' is still trying to write data to the closed pipe, it will trigger a SIGPIPE signal, causing a write error. One solution is not to use this problematic "head -n 1" command, but to use mptcp_lib_get_info_value() helper defined in mptcp_lib.sh to get the value of 'token'.

2025-04-23perf tools: Fix arm64 build by generating unistd_64.hJames Clark
Since pulling in the kernel changes in commit 22f72088ffe6 ("tools headers: Update the syscall table with the kernel sources"), arm64 is no longer using a generic syscall header and generates one from the syscall table. Therefore we must also generate the syscall header for arm64 before building Perf. Add it as a dependency to libperf which uses one syscall number. Perf uses more, but as libperf is a dependency of Perf it will be generated for both. Future platforms that need this will have to add their own syscall-y targets in libperf manually. Unfortunately the arch specific files that do this (e.g. arch/arm64/include/asm/Kbuild) can't easily be imported into the Perf build. But Perf only needs a subset of the generated files anyway, so redefining them is probably the correct thing to do.

2025-04-22PM: sleep: Use two lines for "Restarting..." / "done" messagesAndrew Sayers
Other messages are occasionally printed between these two, for example: [203104.106534] Restarting tasks ... [203104.106559] mei_hdcp 0000:00:16.0-b638ab7e-94e2-4ea2-a552-d1c54b627f04: bound 0000:00:02.0 (ops i915_hdcp_ops [i915]) [203104.112354] done. This seems to be a timing issue, seen in two of the eleven hibernation exits in my current `dmesg` output. When printed on its own, the "done" message has the default log level. This makes the output of `dmesg --level=warn` quite misleading. Add enough context for the "done" messages to make sense on their own, and use the same log level for all messages. Change the messages to "<event>..." / "Done <event>.", unlike a449dfbfc089 which uses "<event>..." / "<event> completed.". Front-loading the unique part of the message makes it easier to scan the log, and reduces ambiguity for users who aren't confident in their English comprehension.

git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing fixes from Steven Rostedt: - Initialize hash variables in ftrace subops logic The fix that simplified the ftrace subops logic opened a path where some variables could be used without being initialized, and done subtly where the compiler did not catch it. Initialize those variables to the EMPTY_HASH, which is the default hash. - Reinitialize the hash pointers after they are freed Some of the hash pointers in the subop logic were freed but may still be referenced later. To prevent use-after-free bugs, initialize them back to the EMPTY_HASH. - Free the ftrace hashes when they are replaced The fix that simplified the subops logic updated some hash pointers, but left the original hash that they were pointing to where they are no longer used. This caused a memory leak. Free the hashes that are pointed to by the pointers when they are replaced. - Fix size initialization of ftrace direct function hash The ftrace direct function hash used by BPF initialized the hash size incorrectly. It checked the size of items to a hard coded 32, which made the hash bit size of 5. The hash size is supposed to be limited by the bit size of the hash, as the bitmask is allowed to be greater than 5. Rework the size check to first pass the number of elements to fls() and then compare that to FTRACE_HASH_MAX_BITS before allocating the hash. - Fix format output of ftrace_graph_ent_entry event The field depth of the ftrace_graph_ent_entry event is of size 4 but the output showed it as unsigned long and use "%lu". Change it to unsigned int and use "%u" in the print format that is displayed to user space. - Fix the trace event filter on strings Events can be filtered on numbers or string values. The return value checked from strncpy_from_kernel_nofault() and strncpy_from_user_nofault() was used to determine if reading the strings would fault or not. It would return fault if the value was non zero, which is basically meant that it was always considering the read as a fault. - Add selftest to test trace event string filtering In order to catch the breakage of the string filtering, add a self test to make sure that it continues to work. * tag 'trace-v6.15-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: tracing: selftests: Add testing a user string to filters tracing: Fix filter string testing ftrace: Fix type of ftrace_graph_ent_entry.depth ftrace: fix incorrect hash size in register_ftrace_direct() ftrace: Free ftrace hashes after they are replaced in the subops code ftrace: Reinitialize hash to EMPTY_HASH after freeing ftrace: Initialize variables for ftrace_startup/shutdown_subops()
