* | | | net: fix kernel deadlock with interface rename and netdev name retrieval.Nicolas Schichan2013-06-263-30/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the kernel (compiled with CONFIG_PREEMPT=n) is performing the rename of a network interface, it can end up waiting for a workqueue to complete. If userland is able to invoke a SIOCGIFNAME ioctl or a SO_BINDTODEVICE getsockopt in between, the kernel will deadlock due to the fact that read_secklock_begin() will spin forever waiting for the writer process (the one doing the interface rename) to update the devnet_rename_seq sequence. This patch fixes the problem by adding a helper (netdev_get_name()) and using it in the code handling the SIOCGIFNAME ioctl and SO_BINDTODEVICE setsockopt. The netdev_get_name() helper uses raw_seqcount_begin() to avoid spinning forever, waiting for devnet_rename_seq->sequence to become even. cond_resched() is used in the contended case, before retrying the access to give the writer process a chance to finish. The use of raw_seqcount_begin() will incur some unneeded work in the reader process in the contended case, but this is better than deadlocking the system.

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.

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. I think these are all micro-fixes that shouldn't cause any trouble. Please let me know if there are problems! ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

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.

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.

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).

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.

The downside of this is that we no longer send the HCI_Delete_Stored_Link_Key command for Bluetooth 1.1 controllers since HCI_Read_Local_Supported_Command was introduced in version 1.2, but this is an acceptable penalty as the command in question shouldn't affect critical behavior.

Steve West recently asked me why I removed the q->error = 0 initalization from sctp_outq_teardown. I did so because I was operating under the impression that sctp_outq_init would properly initalize that value for us, but it doesn't. sctp_outq_init operates under the assumption that the outq struct is all 0's (as it is when called from sctp_association_init), but using it in __sctp_outq_teardown violates that assumption. We should do a memset in sctp_outq_init to ensure that the entire structure is in a known state there instead.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If users apply shaper to vti tunnel then it will cause a kernel crash. The problem seems to be due to the vti_tunnel_xmit function not clearing skb->opt field before passing the packet to xfrm tunneling code.

A device name can be of size IFNAMSIZ (== 16), meaning we might leave the destination string unterminated. Thus, use strlcpy() and also sizeof() while we're at it. We need to memset the data area beforehand, since strlcpy does not padd the remaining buffer with zeroes for user space, so that we do not possibly leak anything.

This fix enables batman-adv initialisation to do not fail just because somewhere else in the system another code path is holding the rtnl lock. It is easy to see the problem when batman-adv is trying to start together with other networking components. - fix the routing protocol forwarding policy by enhancing the duplicate control packet detection. When the right circumstances trigger the issue, some nodes in the network become totally unreachable, so breaking the mesh connectivity. - fix the Bridge Loop Avoidance component by not running the originator address change handling routine when the component is disabled. The routine was generating useless packets that were sent over the network. Signed-off-by: David S. Miller <davem@davemloft.net>
