netfilter: nf_nat_sip: fix incorrect handling of EBUSY for RTCP expectation
We're hitting bug while trying to reinsert an already existing expectation: kernel BUG at kernel/timer.c:895! invalid opcode: 0000 [#1] SMP [...] Call Trace: <IRQ> [<ffffffffa0069563>] nf_ct_expect_related_report+0x4a0/0x57a [nf_conntrack] [<ffffffff812d423a>] ? in4_pton+0x72/0x131 [<ffffffffa00ca69e>] ip_nat_sdp_media+0xeb/0x185 [nf_nat_sip] [<ffffffffa00b5b9b>] set_expected_rtp_rtcp+0x32d/0x39b [nf_conntrack_sip] [<ffffffffa00b5f15>] process_sdp+0x30c/0x3ec [nf_conntrack_sip] [<ffffffff8103f1eb>] ? irq_exit+0x9a/0x9c [<ffffffffa00ca738>] ? ip_nat_sdp_media+0x185/0x185 [nf_nat_sip] We have to remove the RTP expectation if the RTCP expectation hits EBUSY since we keep trying with other ports until we succeed.
