2025-04-22tools/nolibc: implement width padding in printf()Thomas Weißschuh1-1/+16
printf can pad each argument to a certain width. Implement this for compatibility with the kselftest harness. Currently only padding with spaces is supported. Signed-off-by: Thomas Weißschuh <thomas.weissschuh@linutronix.de> Acked-by: Willy Tarreau <w@1wt.eu>

2025-04-22tools/nolibc: allow limiting of printf destination sizeThomas Weißschuh1-6/+10
snprintf() allows limiting the output buffer, while still returning the number of all bytes that would have been written. Implement the limitation logic in preparation for snprintf(). Signed-off-by: Thomas Weißschuh <thomas.weissschuh@linutronix.de> Acked-by: Willy Tarreau <w@1wt.eu>

2025-04-22tools/nolibc: add getopt()Thomas Weißschuh3-0/+103
Introduce a getopt() implementation based on the one from musl. The only deviations are adaption to the kernel coding style and nolibc infrastructure and removal of multi-byte support. Signed-off-by: Thomas Weißschuh <thomas.weissschuh@linutronix.de> Acked-by: Willy Tarreau <w@1wt.eu>
2025-04-22tools/nolibc: add dprintf() and vdprintf()Thomas Weißschuh1-0/+24
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>

2025-04-22tools/nolibc: add _exit()Thomas Weißschuh1-1/+7
_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 Weißschuh1-2/+2
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 Weißschuh1-0/+2
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.

2025-04-09bpf: Clarify the meaning of BPF_F_PSEUDO_HDRPaul Chaignon1-1/+1
In the bpf_l4_csum_replace helper, the BPF_F_PSEUDO_HDR flag should only be set if the modified header field is part of the pseudo-header. If you modify for example the UDP ports and pass BPF_F_PSEUDO_HDR, inet_proto_csum_replace4 will update skb->csum even though it shouldn't (the port and the UDP checksum updates null each other).
