sctp: check policy more carefully when getting pr status
When getting pr_assocstatus and pr_streamstatus by sctp_getsockopt, it doesn't correctly process the case when policy is set with SCTP_PR_SCTP_ALL | SCTP_PR_SCTP_MASK. It even causes a slab-out-of-bounds in sctp_getsockopt_pr_streamstatus(). This patch fixes it by return -EINVAL for this case. Fixes: 0ac1077e3a54 ("sctp: get pr_assoc and pr_stream all status with SCTP_PR_SCTP_ALL") Reported-by: syzbot+5da0d0a72a9e7d791748@syzkaller.appspotmail.com Suggested-by: Marcelo Ricardo Leitner <marcelo.leitner@gmail.com> Signed-off-by: Xin Long <lucien.xin@gmail.com> Signed-off-by: David S.
