2019-08-29	selftests/bpf: fix sendmsg6_prog on s390	Ilya Leoshkevich	1	-2/+1
	[ Upstream commit c8eee4135a456bc031d67cadc454e76880d1afd8 ] "sendmsg6: rewrite IP & port (C)" fails on s390, because the code in sendmsg_v6_prog() assumes that (ctx->user_ip6[0] & 0xFFFF) refers to leading IPv6 address digits, which is not the case on big-endian machines. Since checking bitwise operations doesn't seem to be the point of the test, replace two short comparisons with a single int comparison.

2018-05-28	selftests/bpf: Selftest for sys_sendmsg hooks	Andrey Ignatov	1	-0/+60
	Add selftest for BPF_CGROUP_UDP4_SENDMSG and BPF_CGROUP_UDP6_SENDMSG attach types. Try to sendmsg(2) to specific IP:port and test that: * source IP is overridden as expected. * remote IP:port pair is overridden as expected; Both UDPv4 and UDPv6 are tested. Output: # test_sock_addr.sh 2>/dev/null Wait for testing IPv4/IPv6 to become available ... OK ... pre-existing test-cases skipped ... Test case: sendmsg4: load prog with wrong expected attach type ..
