2013-06-25net/tg3: Avoid delay during MMIO accessGavin Shan
When the EEH error is the result of a fenced host bridge, MMIO accesses can be very slow (milliseconds) to timeout and return all 1's, thus causing the driver various timeout loops to take way too long and trigger soft-lockup warnings (in addition to taking minutes to recover). It might be worthwhile to check if for any of these cases, ffffffff is a valid possible value, and if not, bail early since that means the HW is either gone or isolated. In the meantime, checking that the PCI channel is offline would be workaround of the problem.

2013-06-25ipv6: check return value of ipv6_get_lladdrHannes Frederic Sowa
We should check the return value of ipv6_get_lladdr in inet6_set_iftoken. A possible situation, which could leave ll_addr unassigned is, when the user removed her link-local address but a global scoped address was already set. In this case the interface would still be IF_READY and not dead. In that case the RS source address is some value from the stack. v2: Daniel Borkmann noted a small indent inconstancy; no semantic changes.

git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless John W. Linville says: ==================== A few more late-breaking fixes hoping for 3.10... Regarding the Bluetooth fix, Gustavo says: "A important fix to 3.10, this patch fixes an issues that was preventing the l2cap info response command to be handled properly." Also for that Bluetooth fix, Johan adds: "Once the code gives up parsing this PDU it also gives up essential parts of the L2CAP connection creation process, i.e. without this patch the stack will fail to establish connections properly." Moving onto ath9k, Felix Fietkau fixes an RCU locking issue in the transmit path. As for ath9k_htc, Sujith Manoharan fixes some authentication timeouts by ensuring that a chip reset is done when IDLE is turned off.

2013-06-25ipv6: Process unicast packet with Router Alert by checking flag in skb.YOSHIFUJI Hideaki / 吉藤英明
Router Alert option is marked in skb. Previously, IP6CB(skb)->ra was set to positive value for such packets. Since commit dd3332bf ("ipv6: Store Router Alert option in IP6CB directly."), IP6SKB_ROUTERALERT is set in IP6CB(skb)->flags, and the value of Router Alert option (in network byte order) is set to IP6CB(skb)->ra for such packets. Multicast forwarding path uses that flag and value, but unicast forwarding path does not use the flag and misuses IP6CB(skb)->ra value.

In commit 4cdd3408 ("netfilter: nf_conntrack_ipv6: improve fragmentation handling"), an sk_buff leak was introduced when dealing with reassembled packets by grabbing a reference to the original skb instead of the reassembled skb. At this point, the leak only impacted conntracks with an associated helper. In commit 58a317f1 ("netfilter: ipv6: add IPv6 NAT support"), the bug was expanded to include all reassembled packets with unconfirmed conntracks.

2013-06-19nl80211: fix attrbuf access race by allocating a separate oneJohannes Berg
Since my commit 3713b4e364 ("nl80211: allow splitting wiphy information in dumps"), nl80211_dump_wiphy() uses the global nl80211_fam.attrbuf for parsing the incoming data. This wouldn't be a problem if it only did so on the first dump iteration which is locked against other commands in generic netlink, but due to space constraints in cb->args (the needed state doesn't fit) I decided to always parse the original message. That's racy though since nl80211_fam.attrbuf could be used by some other parsing in generic netlink concurrently. For now, fix this by allocating a separate parse buffer (it's a bit too big for the stack, currently 1448 bytes on 64-bit). For -next, I'll change the code to parse into the global buffer in the first round only and then allocate a smaller buffer to keep the data in cb->args.

As part of the push to add 802.1ad server provider tagging support to the kernel the VLAN features flags were renamed. Unfortunately the kernel name for the VLAN hardware acceleration features that the kernel shows user space was included in the rename, which broke ethtool (txvlan and rxvlan options do not work). This patch restores the original names, i.e. the original ABI. If we wanted to make clear to users that we are refering to CTAGs we can always change ethtool's short_name and long_name for these features (for example something along the lines of txvlan -> txvlan-ctag, tx-vlan-offload -> tx-vlan-ctag-offload).

git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless into wireless John W. Linville says: ==================== This will probably be the last batch of wireless fixes intended for 3.10. Many of these are one- or two-liners, and a couple of others are mostly relocating existing code to avoid races or to limit the code to effecting specific hardware, etc. The mac80211 fixes have a couple of exceptions to the above. Regarding those, Johannes says: "Following davem's complaint about my patch, here's a new pull request w/o the patch he was complaining about, but instead with the const fix rolled into the fix. I have a fix for radar detection, one for rate control and a workaround for broken HT APs which is a regression fix because we didn't rely on them to be correct before." Johannes also sends some iwlwifi fixes: "I picked up Nikolay's patch for the chain noise calibration bug that seems to have been there forever, a fix from Emmanuel for setting TX flags on BAR frames and a fix of my own to avoid printing request_module() errors if the kernel isn't even modular. We also have our own version of Stanislaw's fix for rate control." Along with those... Anderson Lizardo fixes a Bluetooth memory corruption bug when an MTU value is set to too small of a value. Arend van Spriel sends a revised brcmsmac bug that fixes a regression caused by a bad return value in an earlier patch. He also sends a brcmfmac fix to avoid an oops when loading the driver at boot. Daniel Drake fixes a race condition in btmrvl that causes hangs on suspend for OLPC hardware. Johan Hedberg adds a check to avoid sending a HCI_Delete_Stored_Link_Key command to devices that don't support them, avoiding some scary looking log spam. Stanislaw Gruszka gives us a fix for iwlegacy to be able to use rates higher than 1Mb/s on older wireless networks. He also sends an rt2x00 fix to reinstate older tx power handling behavior for some devices that didn't work well with the current code. ==================== Signed-off-by: David S.

Pablo Neira Ayuso says: ==================== The following patchset contains Netfilter fixes. They are targeted to the TCP option targets, that have receive some scrinity in the last week. The changes are: * Fix TCPOPTSTRIP, it stopped working in the forward chain as tcp_hdr uses skb->transport_header, and we cannot use that in the forwarding case, from myself. * Fix default IPv6 MSS in TCPMSS in case of absence of TCP MSS options, from Phil Oester. * Fix missing fragmentation handling again in TCPMSS, from Phil Oester. ==================== Signed-off-by: David S.
