Pablo Neira Ayuso says: ==================== Netfilter fixes for net The following patch contains Netfilter fixes for your net tree, they are: 1) nf_log_unregister() should only set to NULL the logger that is being unregistered, instead of everything else. Patch from Florian Westphal. 2) Fix a crash when accessing physoutdev from PREROUTING in br_netfilter. This is partially reverting the patch to shrink nf_bridge_info to 32 bytes. Also from Florian. 3) Use existing match/target extensions in the internal nft_compat extension lists when the extension is family unspecific (ie. NFPROTO_UNSPEC). 4) Wait for rcu grace period before leaving nf_log_unregister(). ==================== Signed-off-by:David S. Miller <davem@davemloft.net>

This reverts commit 1298267b. That commit claim that the Vitesse VSC8641 is compatible with Vitesse 82xx. But this is not true. It seems that all the registers used in Vitesse phy driver are not compatible between 8641 and 82xx. It does cause malfunction of the Ethernet on p1010rdb-pa board. So we definitely need a rework in order to support the 8641 phy in this driver. Signed-off-by:

Man page of ip-route(8) says following about route types: unreachable - these destinations are unreachable. Packets are dis‐ carded and the ICMP message host unreachable is generated. The local senders get an EHOSTUNREACH error. blackhole - these destinations are unreachable. Packets are dis‐ carded silently. The local senders get an EINVAL error. prohibit - these destinations are unreachable. Packets are discarded and the ICMP message communication administratively prohibited is generated. The local senders get an EACCES error. In the inet6 address family, this was correct, except the local senders got ENETUNREACH error instead of EHOSTUNREACH in case of unreachable route. In the inet address family, all three route types generated ICMP message net unreachable, and the local senders got ENETUNREACH error. In both address families all three route types now behave consistently with documentation. Signed-off-by:

Tracking idle time in bictcp_cwnd_event() is imprecise, as epoch_start is normally set at ACK processing time, not at send time. Doing a proper fix would need to add an additional state variable, and does not seem worth the trouble, given CUBIC bug has been there forever before Jana noticed it. Let's simply not set epoch_start in the future, otherwise bictcp_update() could overflow and CUBIC would again grow cwnd too fast. This was detected thanks to a packetdrill test Neal wrote that was flaky before applying this fix. Fixes: 30927520 ("tcp_cubic: better follow cubic curve after idle period") Signed-off-by:

vxlan_setup is called when allocating the net_device, i.e. way before vxlan_newlink (or vxlan_dev_configure) is called. This means vxlan->default_dst is actually unset in vxlan_setup and the condition that sets needed_headroom always takes the else branch. Set the needed_headrom at the point when we have the information about the address family available.

For arcnet the bare minimum header only contains the 4 bytes to specify source, dest and offset (1, 1 and 2 bytes respectively). The corresponding struct is struct arc_hardware. The struct archdr contains additionally a union of possible soft headers. When doing $insertusecasehere packets might well include short (or even no?) soft headers. For this reason only use arc_hardware instead of archdr to determine the hard_header_len for an arcnet device. Signed-off-by:

David Woodhouse reports skb_under_panic when we try to push ethernet header to fragmented ipv6 skbs: skbuff: skb_under_panic: text:c1277f1e len:1294 put:14 head:dec98000 data:dec97ffc tail:0xdec9850a end:0xdec98f40 dev:br-lan [..] ip6_finish_output2+0x196/0x4da David further debugged this: [..] offending fragments were arriving here with skb_headroom(skb)==10. Which is reasonable, being the Solos ADSL card's header of 8 bytes followed by 2 bytes of PPP frame type. The problem is that if netfilter ipv6 defragmentation is used, skb_cow() in ip6_forward will only see reassembled skb. Therefore, headroom is overestimated by 8 bytes (we pulled fragment header) and we don't check the skbs in the frag_list either. We can't do these checks in netfilter defrag since outdev isn't known yet. Furthermore, existing tests in ip6_fragment did not consider the fragment or ipv6 header size when checking headroom of the fraglist skbs. While at it, also fix a skb leak on memory allocation -- ip6_fragment must consume the skb. I tested this e1000 driver hacked to not allocate additional headroom (we end up in slowpath, since LL_RESERVED_SPACE is 16). If 2 bytes of headroom are allocated, fastpath is taken (14 byte ethernet header was pulled, so 16 byte headroom available in all fragments). Reported-by:

A comment in include/linux/skbuff.h says that: * Various parts of the networking layer expect at least 32 bytes of * headroom, you should not reduce this. This was demonstrated by a panic when handling fragmented IPv6 packets: http://marc.info/?l=linux-netdev&m=144236093519172&w=2 It's not entirely clear if that comment is still valid — and if it is, perhaps netif_rx() ought to be enforcing it with a warning. But either way, it is rather stupid from a performance point of view for us to be receiving packets into a buffer which doesn't have enough room to prepend an Ethernet header — it means that *every* incoming packet is going to be need to be reallocated. So let's fix that. Signed-off-by:

Steffen reported that the recent change to add oif to dst lookups breaks the VTI use case. The problem is that with the oif set in the flow struct the comparison to the nh_oif is triggered. Fix by splitting the FLOWI_FLAG_VRFSRC into 2 flags -- one that triggers the vrf device cache bypass (FLOWI_FLAG_VRFSRC) and another telling the lookup to not compare nh oif (FLOWI_FLAG_SKIP_NH_OIF).

Masks were added to OVS flows in a way that was backwards compatible with userspace programs that did not generate masks. As a result, it is possible that we may receive flows that do not have a mask and we need to synthesize one. Generating a mask requires iterating over attributes and descending into nested attributes. For each level we need to know the size to generate the correct mask. We do this with a linked table of attribute types. Although the logic to handle these nested attributes was there in concept, there are a number of bugs in practice. Examples include incomplete links between tables, variable length attributes being treated as nested and missing sanity checks. Signed-off-by:

I get the following trace by adding WARN_ON_ONCE(newrefcnt < 0) to dst_release(): [ 312.760432] ------------[ cut here ]------------ [ 312.774664] WARNING: CPU: 2 PID: 10263 at net/core/dst.c:288 dst_release+0xf3/0x100() [ 312.776041] Modules linked in: k10temp coretemp hwmon ip6_gre ip6_tunnel tunnel6 ipmi_devintf ipmi_ms\ ghandler ip6table_filter ip6_tables xt_NFLOG nfnetlink_log nfnetlink xt_comment xt_statistic iptable_fil\ ter ip_tables x_tables nfsv3 nfs_acl nfs fscache lockd grace mptctl netconsole autofs4 rpcsec_gss_krb5 a\ uth_rpcgss oid_registry sunrpc ipv6 dm_mod loop iTCO_wdt iTCO_vendor_support serio_raw rtc_cmos pcspkr i\ 2c_i801 i2c_core lpc_ich mfd_core ehci_pci ehci_hcd e1000e mlx4_en ptp pps_core vxlan udp_tunnel ip6_udp\ _tunnel mlx4_core sg button ext3 jbd mpt2sas raid_class [ 312.785302] CPU: 2 PID: 10263 Comm: netperf Not tainted 4.2.0-rc8-00046-g4db9b63-dirty #15 [ 312.791695] Hardware name: Quanta Freedom /Windmill-EP, BIOS F03_3B04 09/12/2013 [ 312.792965] ffffffff819dca2c ffff8811dfbdf6f8 ffffffff816537de ffff88123788fdb8 [ 312.794263] 0000000000000000 ffff8811dfbdf738 ffffffff81052646 ffff8811dfbdf768 [ 312.795593] ffff881203a98180 00000000ffffffff ffff88242927a000 ffff88120a2532e0 [ 312.796946] Call Trace: [ 312.797380] [<ffffffff816537de>] dump_stack+0x45/0x57 [ 312.798288] [<ffffffff81052646>] warn_slowpath_common+0x86/0xc0 [ 312.799699] [<ffffffff8105273a>] warn_slowpath_null+0x1a/0x20 [ 312.800852] [<ffffffff8159f9b3>] dst_release+0xf3/0x100 [ 312.801834] [<ffffffffa03f1308>] ip6_tnl_dst_store+0x48/0x70 [ip6_tunnel] [ 312.803738] [<ffffffffa03fd0b6>] ip6gre_xmit2+0x536/0x720 [ip6_gre] [ 312.804774] [<ffffffffa03fd40a>] ip6gre_tunnel_xmit+0x16a/0x410 [ip6_gre] [ 312.805986] [<ffffffff8159934b>] dev_hard_start_xmit+0x23b/0x390 [ 312.808810] [<ffffffff815a2f5f>] ? neigh_destroy+0xef/0x140 [ 312.809843] [<ffffffff81599a6c>] __dev_queue_xmit+0x48c/0x4f0 [ 312.813931] [<ffffffff81599ae3>] dev_queue_xmit_sk+0x13/0x20 [ 312.814993] [<ffffffff815a0832>] neigh_direct_output+0x12/0x20 [ 312.817448] [<ffffffffa021d633>] ip6_finish_output2+0x183/0x460 [ipv6] [ 312.818762] [<ffffffff81306fc5>] ? find_next_bit+0x15/0x20 [ 312.819671] [<ffffffffa021fd79>] ip6_finish_output+0x89/0xe0 [ipv6] [ 312.820720] [<ffffffffa021fe14>] ip6_output+0x44/0xe0 [ipv6] [ 312.821762] [<ffffffff815c8809>] ? nf_hook_slow+0x69/0xc0 [ 312.823123] [<ffffffffa021d232>] ip6_xmit+0x242/0x4c0 [ipv6] [ 312.824073] [<ffffffffa021c9f0>] ? ac6_proc_exit+0x20/0x20 [ipv6] [ 312.825116] [<ffffffffa024c751>] inet6_csk_xmit+0x61/0xa0 [ipv6] [ 312.826127] [<ffffffff815eb590>] tcp_transmit_skb+0x4f0/0x9b0 [ 312.827441] [<ffffffff815ed267>] tcp_connect+0x637/0x7a0 [ 312.828327] [<ffffffffa0245906>] tcp_v6_connect+0x2d6/0x550 [ipv6] [ 312.829581] [<ffffffff81606f05>] __inet_stream_connect+0x95/0x2f0 [ 312.830600] [<ffffffff810ae13a>] ? hrtimer_try_to_cancel+0x1a/0xf0 [ 312.833456] [<ffffffff812fba19>] ? timerqueue_add+0x59/0xb0 [ 312.834407] [<ffffffff81607198>] inet_stream_connect+0x38/0x50 [ 312.835886] [<ffffffff8157cb17>] SYSC_connect+0xb7/0xf0 [ 312.840035] [<ffffffff810af6d3>] ? do_setitimer+0x1b3/0x200 [ 312.840983] [<ffffffff810af75a>] ? alarm_setitimer+0x3a/0x70 [ 312.841941] [<ffffffff8157d7ae>] SyS_connect+0xe/0x10 [ 312.842818] [<ffffffff81659297>] entry_SYSCALL_64_fastpath+0x12/0x6a [ 312.844206] ---[ end trace 43f3ecd86c3b1313 ]--- ==================== Signed-off-by:
