[PATCH bpf-next v2 1/2] selftests/bpf: Add struct send_recv_arg

From: Geliang Tang Avoid setting total_bytes and stop as global variables, this patch adds a new struct named send_recv_arg to pass arguments between threads. Put these two variables together with fd into this struct and pass it to server thread, so that server thread can access these two variabl

[PATCH bpf-next v2 2/2] selftests/bpf: Export send_recv_data helper

From: Geliang Tang This patch extracts the code to send and receive data into a new helper named send_recv_data() in network_helpers.c and export it in network_helpers.h. This helper will be used for MPTCP BPF selftests. Signed-off-by: Geliang Tang --- tools/testing/selftests/bpf/network_help

[PATCH bpf-next v2 0/2] export send_byte and send_recv_data

From: Geliang Tang Address Martin's comments for v1 (thanks.) - drop patch 1, "export send_byte helper". - drop "WRITE_ONCE(arg.stop, 0)". - rebased. send_recv_data will be re-used in MPTCP bpf tests, but not included in this set because it depends on other patches that have not been in the b

[PATCH AUTOSEL 6.1 12/13] bpf: Check bloom filter map value size

From: Andrei Matei [ Upstream commit a8d89feba7e54e691ca7c4efc2a6264fa83f3687 ] This patch adds a missing check to bloom filter creating, rejecting values above KMALLOC_MAX_SIZE. This brings the bloom map in line with many other map types. The lack of this protection can cause kernel crashes fo
