-Subject: net: sctp: fix ipv6 ipsec encryption bug in sctp_v6_xmit
-
-Alan Chester reported an issue with IPv6 on SCTP that IPsec traffic is not
-being encrypted, whereas on IPv4 it is. Setting up an AH + ESP transport
-does not seem to have the desired effect:
-
-SCTP + IPv4:
-
- 22:14:20.809645 IP (tos 0x2,ECT(0), ttl 64, id 0, offset 0, flags [DF], proto AH (51), length 116)
- 192.168.0.2 > 192.168.0.5: AH(spi=0x00000042,sumlen=16,seq=0x1): ESP(spi=0x00000044,seq=0x1), length 72
- 22:14:20.813270 IP (tos 0x2,ECT(0), ttl 64, id 0, offset 0, flags [DF], proto AH (51), length 340)
- 192.168.0.5 > 192.168.0.2: AH(spi=0x00000043,sumlen=16,seq=0x1):
-
-SCTP + IPv6:
-
- 22:31:19.215029 IP6 (class 0x02, hlim 64, next-header SCTP (132) payload length: 364)
- fe80::222:15ff:fe87:7fc.3333 > fe80::92e6:baff:fe0d:5a54.36767: sctp
- 1) [INIT ACK] [init tag: 747759530] [rwnd: 62464] [OS: 10] [MIS: 10]
-
-Moreover, Alan says:
-
- This problem was seen with both Racoon and Racoon2. Other people have seen
- this with OpenSwan. When IPsec is configured to encrypt all upper layer
- protocols the SCTP connection does not initialize. After using Wireshark to
- follow packets, this is because the SCTP packet leaves Box A unencrypted and
- Box B believes all upper layer protocols are to be encrypted so it drops
- this packet, causing the SCTP connection to fail to initialize. When IPsec
- is configured to encrypt just SCTP, the SCTP packets are observed unencrypted.
-
-In fact, using `socat sctp6-listen:3333 -` on one end and transferring "plaintext"
-string on the other end, results in cleartext on the wire where SCTP eventually
-does not report any errors, thus in the latter case that Alan reports, the
-non-paranoid user might think he's communicating over an encrypted transport on
-SCTP although he's not (tcpdump ... -X):
-
- ...
- 0x0030: 5d70 8e1a 0003 001a 177d eb6c 0000 0000 ]p.......}.l....
- 0x0040: 0000 0000 706c 6169 6e74 6578 740a 0000 ....plaintext...
-
-Only in /proc/net/xfrm_stat we can see XfrmInTmplMismatch increasing on the
-receiver side. Initial follow-up analysis from Alan's bug report was done by
-Alexey Dobriyan. Also thanks to Vlad Yasevich for feedback on this.
-
-SCTP has its own implementation of sctp_v6_xmit() not calling inet6_csk_xmit().
-This has the implication that it probably never really got updated along with
-changes in inet6_csk_xmit() and therefore does not seem to invoke xfrm handlers.
-
-SCTP's IPv4 xmit however, properly calls ip_queue_xmit() to do the work. Since
-a call to inet6_csk_xmit() would solve this problem, but result in unecessary
-route lookups, let us just use the cached flowi6 instead that we got through
-sctp_v6_get_dst(). Since all SCTP packets are being sent through sctp_packet_transmit(),
-we do the route lookup / flow caching in sctp_transport_route(), hold it in
-tp->dst and skb_dst_set() right after that. If we would alter fl6->daddr in
-sctp_v6_xmit() to np->opt->srcrt, we possibly could run into the same effect
-of not having xfrm layer pick it up, hence, use fl6_update_dst() in sctp_v6_get_dst()
-instead to get the correct source routed dst entry, which we assign to the skb.
-
-Also source address routing example from 625034113 ("sctp: fix sctp to work with
-ipv6 source address routing") still works with this patch! Nevertheless, in RFC5095
-it is actually 'recommended' to not use that anyway due to traffic amplification [1].
-So it seems we're not supposed to do that anyway in sctp_v6_xmit(). Moreover, if
-we overwrite the flow destination here, the lower IPv6 layer will be unable to
-put the correct destination address into IP header, as routing header is added in
-ipv6_push_nfrag_opts() but then probably with wrong final destination. Things aside,
-result of this patch is that we do not have any XfrmInTmplMismatch increase plus on
-the wire with this patch it now looks like:
-
-SCTP + IPv6:
-
- 08:17:47.074080 IP6 2620:52:0:102f:7a2b:cbff:fe27:1b0a > 2620:52:0:102f:213:72ff:fe32:7eba:
- AH(spi=0x00005fb4,seq=0x1): ESP(spi=0x00005fb5,seq=0x1), length 72
- 08:17:47.074264 IP6 2620:52:0:102f:213:72ff:fe32:7eba > 2620:52:0:102f:7a2b:cbff:fe27:1b0a:
- AH(spi=0x00003d54,seq=0x1): ESP(spi=0x00003d55,seq=0x1), length 296
-
-This fixes Kernel Bugzilla 24412. This security issue seems to be present since
-2.6.18 kernels. Lets just hope some big passive adversary in the wild didn't have
-its fun with that. lksctp-tools IPv6 regression test suite passes as well with
-this patch.

-Commit c8d68e6be1c3b242f1c598595830890b65cea64a
-(tuntap: multiqueue support) only call free_netdev() on error in
-tun_set_iff(). This causes several issues:
-
-- memory of tun security were leaked
-- use after free since the flow gc timer was not deleted and the tfile
- were not detached
-
-This patch solves the above issues.
