Commit 5901b6be attempted to introduce IPv6 support into IRC NAT helper. By doing so, the following code seemed to be removed by accident: ip = ntohl(exp->master->tuplehash[IP_CT_DIR_REPLY].tuple.dst.u3.ip); sprintf(buffer, "%u %u", ip, port); pr_debug("nf_nat_irc: inserting '%s' == %pI4, port %u\n", buffer, &ip, port); This leads to the fact that buffer[] was left uninitialized and contained some stack value. When we call nf_nat_mangle_tcp_packet(), we call strlen(buffer) on excatly this uninitialized buffer. If we are unlucky and the skb has enough tailroom, we overwrite resp. leak contents with values that sit on our stack into the packet and send that out to the receiver. Since the rather informal DCC spec [1] does not seem to specify IPv6 support right now, we log such occurences so that admins can act accordingly, and drop the packet. I've looked into XChat source, and IPv6 is not supported there: addresses are in u32 and print via %u format string. Therefore, restore old behaviour as in IPv4, use snprintf(). The IRC helper does not support IPv6 by now. By this, we can safely use strlen(buffer) in nf_nat_mangle_tcp_packet() and prevent a buffer overflow. Also simplify some code as we now have ct variable anyway. [1] http://www.irchelp.org/irchelp/rfc/ctcpspec.html Fixes: 5901b6be ("netfilter: nf_nat: support IPv6 in IRC NAT helper") Signed-off-by:

In function lowpan_header_create(), we invoke the following code construct: struct ipv6hdr *hdr; ... hdr = ipv6_hdr(skb); ... if (...) memcpy(hc06_ptr + 1, &hdr->flow_lbl[1], 2); else memcpy(hc06_ptr, &hdr, 4); Where the else path of the condition, that is, non-compression path, calls memcpy() with a pointer to struct ipv6hdr *hdr as source, thus two levels of indirection. This cannot be correct, and likely only one level of pointer was intended as source buffer for memcpy() here. Fixes: 44331fe2 ("IEEE802.15.4: 6LoWPAN basic support") Signed-off-by: -

If the hypervisor configures a vlan for the VF via the PF, the expected result is that only packets tagged by said vlan will be received by the VF (and that vlan will be silently removed). Due to an incorrect manipulation of vlan filters in the driver, the VF can receive untagged traffic even if the hypervisor configured some vlan for it. This patch corrects the behaviour.

There are 2 different (related) flows in the slowpath configuration that utilize the same pointer and cast it to different structs; This is obviously incorrect as the intended allocated memory is that of the smaller struct, possibly causing the flow utilizing the larger struct to corrupt other slowpath configuration. Since both flows are exclusive, set the allocated memory to be a union of both structs. Reported-by:

Since commit 52367a76 ("cxgb4/cxgb4vf: Code cleanup to enable T4 Configuration File support"), we have failures like this during cxgb4 probe: cxgb4 0000:01:00.4: bad SGE FL page buffer sizes [65536, 65536] cxgb4: probe of 0000:01:00.4 failed with error -22 This happens whenever software parameters are used, without a configuration file. That happens when the hardware was already initialized (after kexec, or after csiostor is loaded). It happens that these values are acceptable, rendering fl_pg_order equal to 0, which is the case of a hard init when the page size is equal or larger than 65536. Accepting fl_large_pg equal to fl_small_pg solves the issue, and shouldn't cause any trouble besides a possible performance reduction when smaller pages are used. And that can be fixed by a configuration file. Signed-off-by:

Therefore preferred lifetime never becomes deprecated. valid lifetime and preferred lifetime should be set independently, even if valid lifetime is infinity, preferred lifetime must expire correctly (meaning it must eventually become deprecated) Signed-off-by:

VM to VM GSO traffic is broken if it goes through VXLAN or GRE tunnel and the physical NIC on the host supports hardware VXLAN/GRE GSO offload (e.g. bnx2x and next-gen mlx4). Two issues - (VXLAN) VM traffic has SKB_GSO_DODGY and SKB_GSO_UDP_TUNNEL with SKB_GSO_TCP/UDP set depending on the inner protocol. GSO header integrity check fails in udp4_ufo_fragment if inner protocol is TCP. Also gso_segs is calculated incorrectly using skb->len that includes tunnel header. Fix: robust check should only be applied to the inner packet. (VXLAN & GRE) Once GSO header integrity check passes, NULL segs is returned and the original skb is sent to hardware. However the tunnel header is already pulled. Fix: tunnel header needs to be restored so that hardware can perform GSO properly on the original packet. Signed-off-by:

The SCTP outqueue structure maintains a data chunks that are pending transmission, the list of chunks that are pending a retransmission and a length of data in flight. It also tries to keep the emtpy state so that it can performe shutdown sequence or notify user. The problem is that the empy state is inconsistently tracked. It is possible to completely drain the queue without sending anything when using PR-SCTP. In this case, the empty state will not be correctly state as report by Jamal Hadi Salim <jhs@mojatatu.com>. This can cause an association to be perminantly stuck in the SHUTDOWN_PENDING state. Additionally, SCTP is incredibly inefficient when setting the empty state. Even though all the data is availaible in the outqueue structure, we ignore it and walk a list of trasnports. In the end, we can completely remove the extra empty state and figure out if the queue is empty by looking at 3 things: length of pending data, length of in-flight data, and exisiting of retransmit data. All of these are already in the strucutre. Reported-by:

Function llc_conn_ac_inc_vr_by_1() evaluates via macro PDU_GET_NEXT_Vr() into ... llc_sk(sk)->vR = ++llc_sk(sk)->vR & 0xffffffffffffff7f ... but the order in which the side effects take place is undefined because there is no intervening sequence point. As llc_sk(sk)->vR is written in llc_sk(sk)->vR (assignment left-hand side) and written in ++llc_sk(sk)->vR & 0xffffffffffffff7f this might possibly yield undefined behavior. The final value of llc_sk(sk)->vR is ambiguous, because, depending on the order of expression evaluation, the increment may occur before, after, or interleaved with the assignment. In C, evaluating such an expression yields undefined behavior. Since we're doing the increment via PDU_GET_NEXT_Vr() macro and the only place it is being used is from llc_conn_ac_inc_vr_by_1(), in order to increment vR by 1 with a follow-up optimized modulo, rewrite the expression into ((vR + 1) & CONST) in order to fix this.

Second fix was to enable auto-detect mode, thus allowing the Warpcore to select the higher speed protocol between 10G-KR (over CL73), or go down to 1G over CL73 when there's indication for it.

Even with the quirks in commit dabdaf0c (mcs7830: Fix link state detection) there are still spurious link-down events for some chips where the false link-down events count go over a few hundreds. This patch takes a more conservative approach and only looks at link-down events where the link-down state is not combined with other states (e.g. half/full speed, pending frames in SRAM or TX status information valid). In all other cases we assume the link is up. Tested on MCS7830CV-DA (USB ID 9710:7830).

When the vlan code detects that the real device can do TX VLAN offloads in hardware, it tries to arrange for the real device's header_ops to be invoked directly. But it does so illegally, by simply hooking the real device's header_ops up to the VLAN device. This doesn't work because we will end up invoking a set of header_ops routines which expect a device type which matches the real device, but will see a VLAN device instead. Fix this by providing a pass-thru set of header_ops which will arrange to pass the proper real device instead. To facilitate this add a dev_rebuild_header(). There are implementations which provide a ->cache and ->create but not a ->rebuild (f.e. PLIP). So we need a helper function just like dev_hard_header() to avoid crashes. Use this helper in the one existing place where the header_ops->rebuild was being invoked, the neighbour code. With lots of help from Florian Westphal. Signed-off-by:

Pull networking fixes from David Miller: "Some holiday bug fixes for 3.13... There is still one bug I'd like to get fixed before 3.13-final. The vlan code erroneously assignes the header ops of the underlying real device to the VLAN device above it when the real device can hardware offload VLAN handling. That's completely bogus because header ops are tied to the device type, so they only expect to see a 'dev' argument compatible with their ops. The fix is the have the VLAN code use a special set of header ops that does the pass-thru correctly, by calling the underlying real device's header ops but _also_ passing in the real device instead of the VLAN device. That fix is currently waiting some testing. Anyways, of note here: 1) Fix bitmap edge case in radiotap, from Johannes Berg. 2) Fix oops on driver unload in rtlwifi, from Larry Finger. 3) Bonding doesn't do locking correctly during speed/duplex/link changes, from Ding Tianhong. 4) Fix header parsing in GRE code, this bug has been around for a few releases. From Timo Teräs. 5) SIT tunnel driver MTU check needs to take GSO into account, from Eric Dumazet. 6) Minor info leak in inet_diag, from Daniel Borkmann. 7) Info leak in YAM hamradio driver, from Salva Peiró. 8) Fix route expiration state handling in ipv6 routing code, from Li RongQing. 9) DCCP probe module does not check request_module()'s return value, from Wang Weidong. 10) cpsw driver passes NULL device names to request_irq(), from Mugunthan V N. 11) Prevent a NULL splat in RDS binding code, from Sasha Levin. 12) Fix 4G overflow test in tg3 driver, from Nithin Sujir. 13) Cure use after free in arc_emac and fec driver's software timestamp handling, from Eric Dumazet. 14) SIT driver can fail to release the route when iptunnel_handle_offloads() throws an error. From Li RongQing. 15) Several batman-adv fixes from Simon Wunderlich and Antonio Quartulli. 16) Fix deadlock during TIPC socket release, from Ying Xue. 17) Fix regression in ROSE protocol recvmsg() msg_name handling, from Florian Westphal. 18) stmmac PTP support releases wrong spinlock, from Vince Bridgers" * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (73 commits) stmmac: Fix incorrect spinlock release and PTP cap detection. phy: IRQ cannot be shared net: rose: restore old recvmsg behavior xen-netback: fix guest-receive-side array sizes fec: Do not assume that PHY reset is active low tipc: fix deadlock during socket release netfilter: nf_tables: fix wrong datatype in nft_validate_data_load() batman-adv: fix vlan header access batman-adv: clean nf state when removing protocol header batman-adv: fix alignment for batadv_tvlv_tt_change batman-adv: fix size of batadv_bla_claim_dst batman-adv: fix size of batadv_icmp_header batman-adv: fix header alignment by unrolling batadv_header batman-adv: fix alignment for batadv_coded_packet netfilter: nf_tables: fix oops when updating table with user chains netfilter: nf_tables: fix dumping with large number of sets ipv6: release dst properly in ipip6_tunnel_xmit netxen: Correct off-by-one errors in bounds checks net: Add some clarification to skb_tx_timestamp() comment. arc_emac: fix potential use after free ... -

Commit 23616132, "of/irq: Refactor interrupt-map parsing" changed the refcount on the device_node causing an error in of_node_put(): ERROR: Bad of_node_put() on /pci@800000020000000 CPU: 0 PID: 1 Comm: swapper/0 Not tainted 3.13.0-rc3-dirty #2 Call Trace: [c00000003e403500] [c0000000000144fc] .show_stack+0x7c/0x1f0 (unreliable) [c00000003e4035d0] [c00000000070f250] .dump_stack+0x88/0xb4 [c00000003e403650] [c0000000005e8768] .of_node_release+0xd8/0xf0 [c00000003e4036e0] [c0000000005eeafc] .of_irq_parse_one+0x10c/0x280 [c00000003e4037a0] [c0000000005efd4c] .of_irq_parse_pci+0x3c/0x1d0 [c00000003e403840] [c000000000038240] .pcibios_setup_device+0xa0/0x2e0 [c00000003e403910] [c0000000000398f0] .pcibios_setup_bus_devices+0x60/0xd0 [c00000003e403990] [c00000000003b3a4] .__of_scan_bus+0x1a4/0x2b0 [c00000003e403a80] [c00000000003a62c] .pcibios_scan_phb+0x30c/0x410 [c00000003e403b60] [c0000000009fe430] .pcibios_init+0x7c/0xd4 This patch adjusts the refcount in the walk of the interrupt tree. When a match is found, there is no need to increase the refcount on 'out_irq->np' as 'newpar' is already holding a ref. The refcount balance between 'ipar' and 'newpar' is maintained in the skiplevel: goto label. This patch also removes the usage of the device_node variable 'old' which seems useless after the latest changes. Signed-off-by:
