ip6_rt_copy only sets dst.from if ort has flag RTF_ADDRCONF and RTF_DEFAULT. but the prefix routes which did get installed by hand locally can have an expiration, and no any flag combination which can ensure a potential from does never expire, so we should always set the new created dst's from. This also fixes the new created dst is always expired since the ort, which is created by RA, maybe has RTF_EXPIRES and RTF_ADDRCONF, but no RTF_DEFAULT.

Jakub reported while working with nlmon netlink sniffer that parts of the inet_diag_sockid are not initialized when r->idiag_family != AF_INET6. That is, fields of r->id.idiag_src[1 ... 3], r->id.idiag_dst[1 ... 3]. In fact, it seems that we can leak 6 * sizeof(u32) byte of kernel [slab] memory through this. At least, in udp_dump_one(), we allocate a skb in ... rep = nlmsg_new(sizeof(struct inet_diag_msg) + ..., GFP_KERNEL); ... and then pass that to inet_sk_diag_fill() that puts the whole struct inet_diag_msg into the skb, where we only fill out r->id.idiag_src[0], r->id.idiag_dst[0] and leave the rest untouched: r->id.idiag_src[0] = inet->inet_rcv_saddr; r->id.idiag_dst[0] = inet->inet_daddr; struct inet_diag_msg embeds struct inet_diag_sockid that is correctly / fully filled out in IPv6 case, but for IPv4 not. So just zero them out by using plain memset (for this little amount of bytes it's probably not worth the extra check for idiag_family == AF_INET). Similarly, fix also other places where we fill that out. Reported-by: NJakub Zawadzki <darkjames-ws@darkjames.pl> Signed-off-by: NDaniel Borkmann <dborkman@redhat.com> Signed-off-by: NDavid S.

While testing my changes for TSO support in SIT devices, I was using sit0 tunnel which appears to include nopmtudisc flag. But using : ip tun add sittun mode sit remote $REMOTE_IPV4 local $LOCAL_IPV4 \ dev $IFACE We get a tunnel which rejects too long packets because of the mtu check which is not yet GSO aware. erd:~# ip tunnel sittun: ipv6/ip remote 10.246.17.84 local 10.246.17.83 ttl inherit 6rd-prefix 2002::/16 sit0: ipv6/ip remote any local any ttl 64 nopmtudisc 6rd-prefix 2002::/16 This patch is based on an excellent report from Michal Shmidt. In the future, we probably want to extend the MTU check to do the right thing for GSO packets...

Sockets marked with IPV6_PMTUDISC_PROBE (or later IPV6_PMTUDISC_INTERFACE) don't respect this setting when the outgoing interface supports UFO. We had the same problem in IPv4, which was fixed in commit daba287b ("ipv4: fix DO and PROBE pmtu mode regarding local fragmentation with UFO/CORK"). Also IPV6_DONTFRAG mode did not care about already corked data, thus it may generate a fragmented frame even if this socket option was specified. It also did not care about the length of the ipv6 header and possible options. In the error path allow the user to receive the pmtu notifications via both, rxpmtu method or error queue. The user may opted in for both, so deliver the notification to both error handlers (the handlers check if the error needs to be enqueued). Also report back consistent pmtu values when sending on an already cork-appended socket. Signed-off-by: NHannes Frederic Sowa <hannes@stressinduktion.org> Signed-off-by: NDavid S.

Certain dm962x revisions contain an bug, where if a USB bulk transfer retry (E.G. if bulk crc mismatch) happens right after a transfer with odd or maxpacket length, the internal tx hardware fifo gets out of sync causing the interface to stop working. Work around it by adding up to 3 bytes of padding to ensure this situation cannot trigger. This workaround also means we never pass multiple-of-maxpacket size skb's to usbnet, so the length adjustment to handle usbnet's padding of those can be removed.

ipgre_header_parse() needs to parse the tunnel's ip header and it uses mac_header to locate the iphdr. This got broken when gre tunneling was refactored as mac_header is no longer updated to point to iphdr. Introduce skb_pop_mac_header() helper to do the mac_header assignment and use it in ipgre_rcv() to fix msg_name parsing. Bug introduced in commit c5441932 (GRE: Refactor GRE tunneling code.)

The neighbour code sends up an RTM_NEWNEIGH netlink notification if the NUD state of a neighbour cache entry is changed by a timer (e.g. from REACHABLE to STALE), even if the lladdr of the entry has not changed. But an administrative change to the the NUD state of a neighbour cache entry that does not change the lladdr (e.g. via "ip -4 neigh change ... nud ...") does not trigger a netlink notification. This means that netlink listeners will not hear about administrative NUD state changes such as from a resolved state to PERMANENT. This patch changes the neighbor code to generate an RTM_NEWNEIGH message when the NUD state of an entry is changed administratively.
