2025-04-22tools/nolibc: add dprintf() and vdprintf()Thomas Weißschuh
dprintf() and vdprintf() are printf() variants printing directly into a filedescriptor. As FILE in nolibc is based directly on filedescriptors, the implementation is trivial. Signed-off-by: Thomas Weißschuh <thomas.weissschuh@linutronix.de> Acked-by: Willy Tarreau <w@1wt.eu>
2025-04-22Revert "selftests/nolibc: use waitid() over waitpid()"Thomas Weißschuh
nolibc's waitpid() now uses the waitid() syscall internally. This removes the original reasoning for the reverted commit as waitpid() is now available on all platforms and has an easier interface. Switch back to waitpid(). This reverts commit a0bc8947ac731ff95a56e0c1737e69e8c56d5b78. Signed-off-by: Thomas Weißschuh <thomas.weissschuh@linutronix.de> Acked-by: Willy Tarreau <w@1wt.eu>
2025-04-22tools/nolibc: implement waitpid() in terms of waitid()Thomas Weißschuh
The old wait4() syscall used by waitpid() before is not available everywhere. Switch to the waitid() syscall which is the new replacement. Signed-off-by: Thomas Weißschuh <thomas.weissschuh@linutronix.de> Acked-by: Willy Tarreau <w@1wt.eu>

2025-04-22tools/nolibc: add _exit()Thomas Weißschuh
_exit() is the faster variant of exit(), skipping all cleanup actions. As nolibc does not perform any cleanup anyways, the implementation is trivial. Signed-off-by: Thomas Weißschuh <thomas.weissschuh@linutronix.de> Acked-by: Willy Tarreau <w@1wt.eu>

2025-04-22tools/nolibc: use intmax definitions from compilerThomas Weißschuh
The printf format checking in the compiler uses the intmax types from the compiler, not libc. This can lead to compiler errors. Instead use the types already provided by the compiler. Example issue with clang 19 for arm64: nolibc-test.c:30:2: error: format specifies type 'uintmax_t' (aka 'unsigned long') but the argument has type 'uintmax_t' (aka 'unsigned long long') [-Werror,-Wformat] Signed-off-by: Thomas Weißschuh <thomas.weissschuh@linutronix.de> Acked-by: Willy Tarreau <w@1wt.eu>
2025-04-22tools/nolibc: handle intmax_t/uintmax_t in printfThomas Weißschuh
In nolibc intmax_t and uintmax_t are always the same as (unsigned) long long/uint64_t as 128bit numbers are not supported. Even libcs that do support 128bit numbers often fix intmax_t to 64bit as it is used in ABIs and any change would break those.

2025-04-06tools/power turbostat: Increase CPU_SUBSET_MAXCPUS to 8192Justin Ernst
On systems with >= 1024 cpus (in my case 1152), turbostat fails with the error output: "turbostat: /sys/fs/cgroup/cpuset.cpus.effective: cpu str malformat 0-1151" A similar error appears with the use of turbostat --cpu when the inputted cpu range contains a cpu number >= 1024: # turbostat -c 1100-1151 "--cpu 1100-1151" malformed ... Both errors are caused by parse_cpu_str() reaching its limit of CPU_SUBSET_MAXCPUS. It's a good idea to limit the maximum cpu number being parsed, but 1024 is too low. For a small increase in compute and allocated memory, increasing CPU_SUBSET_MAXCPUS brings support for parsing cpu numbers >= 1024.

2025-04-04netlink: specs: rt_addr: pull the ifa- prefix out of the namesJakub Kicinski
YAML specs don't normally include the C prefix name in the name of the YAML attr. Remove the ifa- prefix from all attributes in addr-attrs and specify name-prefix instead. This is a bit risky, hopefully there aren't many users out there.

Pull more io_uring updates from Jens Axboe: "Set of fixes/updates for io_uring that should go into this release. The ublk bits could've gone via either tree - usually I put them in block, but they got a bit mixed this series with the zero-copy supported that ended up dipping into both trees. This contains: - Fix for sendmsg zc, include in pinned pages accounting like we do for the other zc types - Series for ublk fixing request aborting, doing various little cleanups, fixing some zc issues, and adding queue_rqs support - Another ublk series doing some code cleanups - Series cleaning up the io_uring send path, mostly in preparation for registered buffers - Series doing little MSG_RING cleanups - Fix for the newly added zc rx, fixing len being 0 for the last invocation of the callback - Add vectored registered buffer support for ublk. With that, then ublk also supports this feature in the kernel revision where it could generically introduced for rw/net - A bunch of selftest additions for ublk. This is the majority of the diffstat - Silence a KCSAN data race warning for io-wq - Various little cleanups and fixes" * tag 'io_uring-6.15-20250403' of git://git.kernel.dk/linux: (44 commits) io_uring: always do atomic put from iowq selftests: ublk: enable zero copy for stripe target io_uring: support vectored kernel fixed buffer block: add for_each_mp_bvec() io_uring: add validate_fixed_range() for validate fixed buffer selftests: ublk: kublk: fix an error log line selftests: ublk: kublk: use ioctl-encoded opcodes io_uring/zcrx: return early from io_zcrx_recv_skb if readlen is 0 io_uring/net: avoid import_ubuf for regvec send io_uring/rsrc: check size when importing reg buffer io_uring: cleanup {g,s]etsockopt sqe reading io_uring: hide caches sqes from drivers io_uring: make zcrx depend on CONFIG_IO_URING io_uring: add req flag invariant build assertion Documentation: ublk: remove dead footnote selftests: ublk: specify io_cmd_buf pointer type ublk: specify io_cmd_buf pointer type io_uring: don't pass ctx to tw add remote helper io_uring/msg: initialise msg request opcode io_uring/msg: rename io_double_lock_ctx() ...
