| * ath9k: Fix Kconfig for ATH9K_HTCVladimir Kondratiev2013-01-041-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Ath9k consists of 2 different sub-modules: ATH9K and ATH9K_HTC. Both uses common Atheros code from ath.ko and need ATH_COMMON. However, while ATH9K selects ATH_COMMON, ATH9K_HTC does not. As result, if ATH9K_HTC is the only Atheros card selected, compilation fails with unresolved symbols. This patch moves ATH_COMMON selection to the common part for both ATH9K and ATH9K_HTC Signed-off-by: Vladimir Kondratiev <qca_vkondrat@qca.qualcomm.com> Signed-off-by: John W.

| * carl9170: fix -EINVAL bailout during init with !CONFIG_MAC80211_MESHChristian Lamparter2013-01-021-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Sean reported that as of 3.7, his AR9170 device no longer works because the driver fails during initialization. He noted this is due to: "In carl9170/fw.c, ar->hw->wiphy is tagged with NL80211_IFTYPE_MESH_POINT support if the firmware has Content after Beacon Queuing. This is both in interface_modes and the only iface_combinations entry. If CONFIG_MAC80211_MESH is not set, ieee80211_register_hw removes NL80211_IFTYPE_MESH_POINT from interface_modes, but not iface_combinations. wiphy_register then checks to see if every interface type in every interface combination is in interface_modes. NL80211_IFTYPE_MESH_POINT was removed, so you get a WARN_ON warning and it returns -EINVAL, giving up." Unfortunately, the iface_combination (types) feature bitmap in ieee80211_iface_limit is part of a const member in the ieee80211_iface_combination struct. Hence, the MESH_POINT feature flag can't be masked by wiphy_register in the same way as interface_modes in ieee80211_register_hw.

The handlers should only be removed once all bridges are gone, but since we don't keep track of the number of bridge interfaces, it's simpler to do it when the bridge module is unloaded.

Many people don't check the scheduled to be removal file under Documentation, so we follow some less agressive approach to kill this in a year or so. Spotted by Florian Westphal, patch from myself. * Fix race condition in xt_hashlimit that allows to create two or more entries, from myself. * Fix crash if the CT is used due to the recently added facilities to consult the dying and unconfirmed conntrack lists, from myself. ==================== Signed-off-by: David S.

That removal was scheduled for removal since long time ago as described in Documentation/feature-removal-schedule.txt What: xt_NOTRACK Files: net/netfilter/xt_NOTRACK.c When: April 2011 Why: Superseded by xt_CT Still, people may have not notice / may have decided to stick to an old iptables version. I agree with him in that some more conservative approach by spotting some printk to warn users for some time is less agressive. Current iptables 1.4.16.3 already contains the aliasing support that makes it point to the CT target, so upgrading would fix it. Still, the policy so far has been to avoid pushing our users to upgrade. As a solution, this patch recovers the NOTRACK target inside the CT target and it now spots a warning.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For tunnelled ipv6in4 packets, the LOG target (xt_LOG.c) adjusts the start of the mac field to start at the ethernet header instead of the ipv4 header for the tunnel. This patch conforms what is passed by the NFLOG target through nfnetlink to what the LOG target does. Code borrowed from xt_LOG.c.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit b836c99fd6c9 (ipv6: unify conntrack reassembly expire code with standard one) use the standard IPv6 reassembly code(ip6_expire_frag_queue) to handle conntrack reassembly expire. In ip6_expire_frag_queue, it invoke dev_get_by_index_rcu to get which device received this expired packet.so we must save ifindex when NF_conntrack get this packet. With this patch applied, I can see ICMP Time Exceeded sent from the receiver when the sender sent out 1/2 fragmented IPv6 packet.

It is also possible for NEW connections which already have a conntrack entry to be affected by routing changes. This adds a check to drop entries in the NEW+conntrack state when the oif has changed.

It doesn't initialize the pointer to the tcp header within the skb. When the skb is passed to the ixgbe driver for transmit, the ixgbe driver attempts to access the tcp header and crashes. Currently, other drivers (such as our 1G e1000e or igb drivers) don't access the tcp header on transmit unless the TSO option is turned on. <1>BUG: unable to handle kernel NULL pointer dereference at 0000000d <1>IP: [<d081621c>] ixgbe_xmit_frame_ring+0x8cc/0x2260 [ixgbe] <4>*pdpt = 0000000085e5d001 *pde = 0000000000000000 <0>Oops: 0000 [#1] SMP [...] <4>Pid: 0, comm: swapper Tainted: P 2.6.35.12 #1 Greencity/Thurley <4>EIP: 0060:[<d081621c>] EFLAGS: 00010246 CPU: 16 <4>EIP is at ixgbe_xmit_frame_ring+0x8cc/0x2260 [ixgbe] <4>EAX: c7628820 EBX: 00000007 ECX: 00000000 EDX: 00000000 <4>ESI: 00000008 EDI: c6882180 EBP: dfc6b000 ESP: ced95c48 <4> DS: 007b ES: 007b FS: 00d8 GS: 0000 SS: 0068 <0>Process swapper (pid: 0, ti=ced94000 task=ced73bd0 task.ti=ced94000) <0>Stack: <4> cbec7418 c779e0d8 c77cc888 c77cc8a8 0903010a 00000000 c77c0008 00000002 <4><0> cd4997c0 00000010 dfc6b000 00000000 d0d176c9 c77cc8d8 c6882180 cbec7318 <4><0> 00000004 00000004 cbec7230 cbec7110 00000000 cbec70c0 c779e000 00000002 <0>Call Trace: <4> [<d0d176c9>] ? 0xd0d176c9 <4> [<d0d18a4d>] ? 0xd0d18a4d <4> [<411e243e>] ? dev_hard_start_xmit+0x218/0x2d7 <4> [<411f03d7>] ? sch_direct_xmit+0x4b/0x114 <4> [<411f056a>] ? __qdisc_run+0xca/0xe0 <4> [<411e28b0>] ? dev_queue_xmit+0x2d1/0x3d0 <4> [<411e8120>] ? neigh_resolve_output+0x1c5/0x20f <4> [<411e94a1>] ? neigh_update+0x29c/0x330 <4> [<4121cf29>] ? arp_process+0x49c/0x4cd <4> [<411f80c9>] ? nf_hook_slow+0x3f/0xac <4> [<4121ca8d>] ? arp_process+0x0/0x4cd <4> [<4121ca8d>] ? arp_process+0x0/0x4cd <4> [<4121c6d5>] ?

The current lm73 driver casts that return value from a s32 type to a s16 type, then converts it to a temperature in celsius. Because negative temperatures are valid, it is difficult to distinguish between an error code printed to the response buffer and a negative temperature recorded by the sensor. The solution is to evaluate the return value from the i2c functions before performing any temperature calculations. If the i2c function did not succeed, the error code should be passed back through the virtual file system layer instead of being printed into the response buffer.

Can lead to processes attempting access their child reaper and instead following a stale pointer. That waitpid for init can return before all of the processes in the pid namespace have exited is also unfortunate. Avoid these problems by disabling the allocation of new pids in a pid namespace when init dies, instead of when the last process in a pid namespace is reaped.
