selftests/bpf: fix sendmsg6_prog on s390

2019-08-29T06:30:01Z

[ 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.

selftests: bpf: centre kernel bpf objects under new subdir "progs"

2019-02-12T04:31:38Z

At the moment, all kernel bpf objects are listed under BPF_OBJ_FILES. Listing them manually sometimes causing patch conflict when people are adding new testcases simultaneously. It is better to centre all the related source files under a subdir "progs", then auto-generate the object file list.
