Daniel Borkmann cfe9266213 bpf, test, cgroup: Use sk_{alloc,free} for test cases ... commit 435b08ec0094ac1e128afe6cfd0d9311a8c617a7 upstream. BPF test infra has some hacks in place which kzalloc() a socket and perform minimum init via sock_net_set() and sock_init_data(). As a result, the sk's skcd->cgroup is NULL since it didn't go through proper initialization as it would have been the case from sk_alloc(). Rather than re-adding a NULL test in sock_cgroup_ptr() just for this, use sk_{alloc,free}() pair for the test socket. The latter also allows to get rid of the bpf_sk_storage_free() special case. Fixes: 8520e224f547 ("bpf, cgroups: Fix cgroup v2 fallback on v1/v2 mixed mode") Fixes: b7a1848e83 ("bpf: add BPF_PROG_TEST_RUN support for flow dissector") Fixes: 2cb494a36c ("bpf: add tests for direct packet access from CGROUP_SKB") Reported-by: syzbot+664b58e9a40fbb2cec71@syzkaller.appspotmail.com Reported-by: syzbot+33f36d0754d4c5c0e102@syzkaller.appspotmail.com Signed-off-by: Daniel Borkmann <daniel@iogearbox.net> Signed-off-by: Alexei Starovoitov <ast@kernel.org> Tested-by: syzbot+664b58e9a40fbb2cec71@syzkaller.appspotmail.com Tested-by: syzbot+33f36d0754d4c5c0e102@syzkaller.appspotmail.com Link: https://lore.kernel.org/bpf/20210927123921.21535-2-daniel@iogearbox.net Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>		2021-10-27 09:56:56 +02:00
