* mlxsw: spectrum: Mark packets trapped in routerIdo Schimmel2017-07-171-7/+7
| | | | | | | | | | | | | | | | In commit 1c6c6d221e2b ("mlxsw: spectrum: Mirror certain packets to CPU") we marked packets that were mirrored to the CPU, so that they won't be flooded again by the bridge driver. However, certain packets are trapped in the device's router block, after passing through the bridge block where they were potentially flooded. Mark all packets coming from L3 traps, so that they won't be potentially flooded again by the bridge driver.

* inetpeer: remove AVL implementation in favor of RB treeEric Dumazet2017-07-172-347/+92
| | | | | | | | | | | | | | | | | | | | | As discussed in Faro during Netfilter Workshop 2017, RB trees can be used with RCU, using a seqlock. Note that net/rxrpc/conn_service.c is already using this. This patch converts inetpeer from AVL tree to RB tree, since it allows to remove private AVL implementation in favor of shared RB code. $ size net/ipv4/inetpeer.before net/ipv4/inetpeer.after text data bss dec hex filename 3195 40 128 3363 d23 net/ipv4/inetpeer.before 1562 24 0 1586 632 net/ipv4/inetpeer.after The same technique can be used to speed up net/netfilter/nft_set_rbtree.c (removing rwlock contention in fast path) Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S.

* net/unix: drop obsolete fd-recursion limitsDavid Herrmann2017-07-172-24/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | All unix sockets now account inflight FDs to the respective sender. This was introduced in: commit 712f4aad406bb1ed67f3f98d04c044191f0ff593 Author: willy tarreau <w@1wt.eu> Date: Sun Jan 10 07:54:56 2016 +0100 unix: properly account for FDs passed over unix sockets and further refined in: commit 415e3d3e90ce9e18727e8843ae343eda5a58fad6 Author: Hannes Frederic Sowa <hannes@stressinduktion.org> Date: Wed Feb 3 02:11:03 2016 +0100 unix: correctly track in-flight fds in sending process user_struct Hence, regardless of the stacking depth of FDs, the total number of inflight FDs is limited, and accounted. There is no known way for a local user to exceed those limits or exploit the accounting. Furthermore, the GC logic is independent of the recursion/stacking depth as well. It solely depends on the total number of inflight FDs, regardless of their layout. Lastly, the current `recursion_level' suffers a TOCTOU race, since it checks and inherits depths only at queue time. If we consider `A<-B' to mean `queue-B-on-A', the following sequence circumvents the recursion level easily: A<-B B<-C C<-D ... Y<-Z resulting in: A<-B<-C<-...<-Z With all of this in mind, lets drop the recursion limit. It has no additional security value, anymore. On the contrary, it randomly confuses message brokers that try to forward file-descriptors, since any sendmsg(2) call can fail spuriously with ETOOMANYREFS if a client maliciously modifies the FD while inflight.

Now sctp is using it for many structures. All this kind of typedef's using should be removed. This patchset is the part 2 to remove it for another 11 basic structures. Just as the part 1, No any code's logic would be changed in these patches, only cleaning up.

* ip6: fix PMTU discovery when using /127 subnetsVincent Bernat2017-07-171-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The definition of an "anycast destination address" has been tweaked as a side-effect of commit 2647a9b07032 ("ipv6: Remove external dependency on rt6i_gateway and RTF_ANYCAST"). The first address of a point-to-point /127 subnet is now considered as an anycast address. This prevents ICMPv6 errors to be returned to a sender of such a subnet and breaks PMTU discovery. This can be reproduced with: ip link add name out6 type veth peer name in6 ip link add name out7 type veth peer name in7 ip link set mtu 1400 dev out7 ip link set mtu 1400 dev in7 ip netns add next-hop ip netns add next-next-hop ip link set netns next-hop dev in6 ip link set netns next-hop dev out7 ip link set netns next-next-hop dev in7 ip link set up dev out6 ip addr add 2001:db8:1::12/127 dev out6 ip netns exec next-hop ip link set up dev in6 ip netns exec next-hop ip link set up dev out7 ip netns exec next-hop ip addr add 2001:db8:1::13/127 dev in6 ip netns exec next-hop ip addr add 2001:db8:1::14/127 dev out7 ip netns exec next-hop ip route add default via 2001:db8:1::15 ip netns exec next-hop sysctl -qw net.ipv6.conf.all.forwarding=1 ip netns exec next-next-hop ip link set up dev in7 ip netns exec next-next-hop ip addr add 2001:db8:1::15/127 dev in7 ip netns exec next-next-hop ip addr add 2001:db8:1::50/128 dev in7 ip netns exec next-next-hop ip route add default via 2001:db8:1::14 ip netns exec next-next-hop sysctl -qw net.ipv6.conf.all.forwarding=1 ip route add 2001:db8:1::48/123 via 2001:db8:1::13 sleep 4 ping -M do -s 1452 -c 3 2001:db8:1::50 || true ip route get 2001:db8:1::50 Before the patch, we get: 2001:db8:1::50 from :: via 2001:db8:1::13 dev out6 src 2001:db8:1::12 metric 1024 pref medium After the patch, we get: 2001:db8:1::50 via 2001:db8:1::13 dev out6 src 2001:db8:1::12 metric 0 cache expires 578sec mtu 1400 pref medium Fixes: 2647a9b07032 ("ipv6: Remove external dependency on rt6i_gateway and RTF_ANYCAST") Signed-off-by: Vincent Bernat <vincent@bernat.im> Signed-off-by: David S.

Here we add the bits needed to support TCP and UDP packets over IPv6 and turn the offload advertising back on.

| * net: stmmac: revert "support future possible different internal phy mode"LABBE Corentin2017-07-121-7/+3
| | | | | | | | | | | | | | | | | | | | | | | | Since internal phy-mode is reserved for non-xMII protocol we cannot use it with dwmac-sun8i. Furthermore, all DT patchs which comes with this patch were cleaned, so the current state is broken.

| * sfc: don't read beyond unicast address listBert Kenward2017-07-121-5/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | If we have more than 32 unicast MAC addresses assigned to an interface we will read beyond the end of the address table in the driver when adding filters. The next 256 entries store multicast addresses, so we will end up attempting to insert duplicate filters, which is mostly harmless. If we add more than 288 unicast addresses we will then read past the multicast address table, which is likely to be more exciting.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The lower level nl80211 code in cfg80211 ensures that "len" is between 25 and NL80211_ATTR_FRAME (2304). We subtract DOT11_MGMT_HDR_LEN (24) from "len" so thats's max of 2280. However, the action_frame->data[] buffer is only BRCMF_FIL_ACTION_FRAME_SIZE (1800) bytes long so this memcpy() can overflow. memcpy(action_frame->data, &buf[DOT11_MGMT_HDR_LEN], le16_to_cpu(action_frame->len)); Cc: stable@vger.kernel.org # 3.9.x Fixes: 18e2f61db3b70 ("brcmfmac: P2P action frame tx.")
