| 2024-07-29 | selftests/bpf: Fix error compiling bpf_iter_setsockopt.c with musl libc | Tony Ambardar | 1 | -1/+1 | |
| Existing code calls getsockname() with a 'struct sockaddr_in6 *' argument where a 'struct sockaddr *' argument is declared, yielding compile errors when building for mips64el/musl-libc: bpf_iter_setsockopt.c: In function 'get_local_port': bpf_iter_setsockopt.c:98:30: error: passing argument 2 of 'getsockname' from incompatible pointer type [-Werror=incompatible-pointer-types] 98 | if (!getsockname(fd, &addr, &addrlen)) | ^~~~~ | | | struct sockaddr_in6 * In file included from .../netinet/in.h:10, from .../arpa/inet.h:9, from ./test_progs.h:17, from bpf_iter_setsockopt.c:5: .../sys/socket.h:391:23: note: expected 'struct sockaddr * restrict' but argument is of type 'struct sockaddr_in6 *' 391 | int getsockname (int, struct sockaddr *__restrict, socklen_t *__restrict); | ^ cc1: all warnings being treated as errors This compiled under glibc only because the argument is declared to be a "funky" transparent union which includes both types above. Explicitly cast the argument to allow compiling for both musl and glibc.

| 2021-07-23 | bpf: selftest: Test batching and bpf_(get|set)sockopt in bpf tcp iter | Martin KaFai Lau | 1 | -0/+226 | |
| This patch adds tests for the batching and bpf_(get|set)sockopt in bpf tcp iter. It first creates: a) 1 non SO_REUSEPORT listener in lhash2. b) 256 passive and active fds connected to the listener in (a). c) 256 SO_REUSEPORT listeners in one of the lhash2 bucket. The test sets all listeners and connections to bpf_cubic before running the bpf iter. The bpf iter then calls setsockopt(TCP_CONGESTION) to switch each listener and connection from bpf_cubic to bpf_dctcp. The bpf iter has a random_retry mode such that it can return EAGAIN to the usespace in the middle of a batch.
