2011-11-22netfilter: nf_conntrack: make event callback registration per-netnsPablo Neira Ayuso
This patch fixes an oops that can be triggered following this recipe: 0) make sure nf_conntrack_netlink and nf_conntrack_ipv4 are loaded. 1) container is started. 2) connect to it via lxc-console. 3) generate some traffic with the container to create some conntrack entries in its table. 4) stop the container: you hit one oops because the conntrack table cleanup tries to report the destroy event to user-space but the per-netns nfnetlink socket has already gone (as the nfnetlink socket is per-netns but event callback registration is global). To fix this situation, we make the ctnl_notifier per-netns so the callback is registered/unregistered if the container is created/destroyed. Alex Bligh and Alexey Dobriyan originally proposed one small patch to check if the nfnetlink socket is gone in nfnetlink_has_listeners, but this is a very visited path for events, thus, it may reduce performance and it looks a bit hackish to check for the nfnetlink socket only to workaround this situation. As a result, I decided to follow the bigger path choice, which seems to look nicer to me.

2011-11-21netfilter: possible unaligned packet header in ip_route_me_harderPaul Guo
This patch tries to fix the following issue in netfilter: In ip_route_me_harder(), we invoke pskb_expand_head() that rellocates new header with additional head room which can break the alignment of the original packet header. In one of my NAT test case, the NIC port for internal hosts is configured with vlan and the port for external hosts is with general configuration. If we ping an external "unknown" hosts from an internal host, an icmp packet will be sent. We find that in icmp_send()->...->ip_route_me_harder()->pskb_expand_head(), hh_len=18 and current headroom (skb_headroom(skb)) of the packet is 16. After calling pskb_expand_head() the packet header becomes to be unaligned and then our system (arch/tile) panics immediately.

2011-11-18ipv4: fix redirect handlingEric Dumazet
commit f39925dbde77 (ipv4: Cache learned redirect information in inetpeer.) introduced a regression in ICMP redirect handling. It assumed ipv4_dst_check() would be called because all possible routes were attached to the inetpeer we modify in ip_rt_redirect(), but thats not true. commit 7cc9150ebe (route: fix ICMP redirect validation) tried to fix this but solution was not complete. (It fixed only one route) So we must lookup existing routes (including different TOS values) and call check_peer_redir() on them.

2011-11-14ip6_tunnel: copy parms.name after register_netdeviceJosh Boyer
Commit 1c5cae815d removed an explicit call to dev_alloc_name in ip6_tnl_create because register_netdevice will now create a valid name. This works for the net_device itself. However the tunnel keeps a copy of the name in the parms structure for the ip6_tnl associated with the tunnel. parms.name is set by copying the net_device name in ip6_tnl_dev_init_gen. That function is called from ip6_tnl_dev_init in ip6_tnl_create, but it is done before register_netdevice is called so the name is set to a bogus value in the parms.name structure. This shows up if you do a simple tunnel add, followed by a tunnel show: [root@localhost ~]# ip -6 tunnel add remote fec0::100 local fec0::200 [root@localhost ~]# ip -6 tunnel show ip6tnl0: ipv6/ipv6 remote :: local :: encaplimit 0 hoplimit 0 tclass 0x00 flowlabel 0x00000 (flowinfo 0x00000000) ip6tnl%d: ipv6/ipv6 remote fec0::100 local fec0::200 encaplimit 4 hoplimit 64 tclass 0x00 flowlabel 0x00000 (flowinfo 0x00000000) [root@localhost ~]# Fix this by moving the strcpy out of ip6_tnl_dev_init_gen, and calling it after register_netdevice has successfully returned.

When the ahash driver returns -EBUSY, AH4/6 input functions return NET_XMIT_DROP, presumably copied from the output code path. But returning transmit codes on input doesn't make a lot of sense. Since NET_XMIT_DROP is a positive int, this gets interpreted as the next header type (i.e., success). As that can only end badly, remove the check.

The AH4/6 ahash output callbacks pass nexthdr to xfrm_output_resume instead of the error code. This appears to be a copy+paste error from the input case, where nexthdr is expected. This causes the driver to continuously add AH headers to the datagram until either an allocation fails and the packet is dropped or the ahash driver hits a synchronous fallback and the resulting monstrosity is transmitted.

2011-11-09cfg80211: fix bug on regulatory core exit on access to last_requestLuis R. Rodriguez
Commit 4d9d88d1 by Scott James Remnant <keybuk@google.com> added the .uevent() callback for the regulatory device used during the platform device registration. The change was done to account for queuing up udev change requests through udevadm triggers. The change also meant that upon regulatory core exit we will now send a uevent() but the uevent() callback, reg_device_uevent(), also accessed last_request. Right before commiting device suicide we free'd last_request but never set it to NULL so platform_device_unregister() would lead to bogus kernel paging request. Fix this and also simply supress uevents right before we commit suicide as they are pointless. This fix is required for kernels >= v2.6.39 $ git describe --contains 4d9d88d1 v2.6.39-rc1~468^2~25^2^2~21 The impact of not having this present is that a bogus paging access may occur (only read) upon cfg80211 unload time. You may also get this BUG complaint below. Although Johannes could not reproduce the issue this fix is theoretically correct. mac80211_hwsim: unregister radios mac80211_hwsim: closing netlink BUG: unable to handle kernel paging request at ffff88001a06b5ab IP: [<ffffffffa030df9a>] reg_device_uevent+0x1a/0x50 [cfg80211] PGD 1836063 PUD 183a063 PMD 1ffcb067 PTE 1a06b160 Oops: 0000 [#1] PREEMPT SMP DEBUG_PAGEALLOC CPU 0 Modules linked in: cfg80211(-) [last unloaded: mac80211] Pid: 2279, comm: rmmod Tainted: G W 3.1.0-wl+ #663 Bochs Bochs RIP: 0010:[<ffffffffa030df9a>] [<ffffffffa030df9a>] reg_device_uevent+0x1a/0x50 [cfg80211] RSP: 0000:ffff88001c5f9d58 EFLAGS: 00010286 RAX: 0000000000000000 RBX: ffff88001d2eda88 RCX: ffff88001c7468fc RDX: ffff88001a06b5a0 RSI: ffff88001c7467b0 RDI: ffff88001c7467b0 RBP: ffff88001c5f9d58 R08: 000000000000ffff R09: 000000000000ffff R10: 0000000000000000 R11: 0000000000000001 R12: ffff88001c7467b0 R13: ffff88001d2eda78 R14: ffffffff8164a840 R15: 0000000000000001 FS: 00007f8a91d8a6e0(0000) GS:ffff88001fc00000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 000000008005003b CR2: ffff88001a06b5ab CR3: 000000001c62e000 CR4: 00000000000006f0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000ffff0ff0 DR7: 0000000000000400 Process rmmod (pid: 2279, threadinfo ffff88001c5f8000, task ffff88000023c780) Stack: ffff88001c5f9d98 ffffffff812ff7e5 ffffffff8176ab3d ffff88001c7468c2 000000000000ffff ffff88001d2eda88 ffff88001c7467b0 ffff880000114820 ffff88001c5f9e38 ffffffff81241dc7 ffff88001c5f9db8 ffffffff81040189 Call Trace: [<ffffffff812ff7e5>] dev_uevent+0xc5/0x170 [<ffffffff81241dc7>] kobject_uevent_env+0x1f7/0x490 [<ffffffff81040189>] ? sub_preempt_count+0x29/0x60 [<ffffffff814cab1a>] ? _raw_spin_unlock_irqrestore+0x4a/0x90 [<ffffffff81305307>] ? devres_release_all+0x27/0x60 [<ffffffff8124206b>] kobject_uevent+0xb/0x10 [<ffffffff812fee27>] device_del+0x157/0x1b0 [<ffffffff8130377d>] platform_device_del+0x1d/0x90 [<ffffffff81303b76>] platform_device_unregister+0x16/0x30 [<ffffffffa030fffd>] regulatory_exit+0x5d/0x180 [cfg80211] [<ffffffffa032bec3>] cfg80211_exit+0x2b/0x45 [cfg80211] [<ffffffff8109a84c>] sys_delete_module+0x16c/0x220 [<ffffffff8108a23e>] ? trace_hardirqs_on_caller+0x7e/0x120 [<ffffffff814cba02>] system_call_fastpath+0x16/0x1b Code: <all your base are belong to me> RIP [<ffffffffa030df9a>] reg_device_uevent+0x1a/0x50 [cfg80211] RSP <ffff88001c5f9d58> CR2: ffff88001a06b5ab ---[ end trace 147c5099a411e8c0 ]--- Reported-by: Johannes Berg <johannes@sipsolutions.net> Cc: Scott James Remnant <keybuk@google.com> Cc: stable@vger.kernel.org Signed-off-by: Luis R.

2011-11-07Bluetooth: Revert: Fix L2CAP connection establishmentArek Lichwa
This reverts commit 330605423ca6eafafb8dcc27502bce1c585d1b06. The commit introduces regression when two 2.1 devices attempt establish rfcomm channel. Such connection is refused since there's a security block issue on l2cap. It means the link is unencrypted. 2011-09-16 18:08:46.567616 < ACL data: handle 1 flags 0x00 dlen 24 0000: 14 00 40 00 06 00 02 00 0f 35 03 19 12 00 ff ff ..@......5....˙˙ 0010: 35 05 0a 00 00 ff ff 00 5....˙˙. 2011-09-16 18:08:46.572377 > HCI Event: Number of Completed Packets (0x13) plen 5 handle 1 packets 1 2011-09-16 18:08:46.577931 > ACL data: handle 1 flags 0x02 dlen 88 L2CAP(d): cid 0x0040 len 84 [psm 0] 0000: 07 00 02 00 4f 00 4c 35 4a 35 48 09 00 00 0a 00 ....O.L5J5H..... 0010: 01 00 00 09 00 01 35 03 19 12 00 09 00 05 35 03 ......5.......5. 0020: 19 10 02 09 00 09 35 08 35 06 19 12 00 09 01 02 ......5.5....... 0030: 09 02 00 09 01 02 09 02 01 09 00 0a 09 02 02 09 ................ 0040: 00 00 09 02 03 09 00 00 09 02 04 28 01 09 02 05 ...........(.... 0050: 09 00 02 00 .... 2011-09-16 18:08:46.626057 < HCI Command: Authentication Requested (0x01|0x0011) plen 2 handle 1 2011-09-16 18:08:46.627614 > HCI Event: Command Status (0x0f) plen 4 Authentication Requested (0x01|0x0011) status 0x00 ncmd 1 2011-09-16 18:08:46.627675 > HCI Event: Link Key Request (0x17) plen 6 bdaddr 00:00:F2:6A:29:69 2011-09-16 18:08:46.634999 < HCI Command: Link Key Request Reply (0x01|0x000b) plen 22 bdaddr 00:00:F2:6A:29:69 key 58CD393179FC902E5E8F512A855EE532 2011-09-16 18:08:46.683278 > HCI Event: Command Complete (0x0e) plen 10 Link Key Request Reply (0x01|0x000b) ncmd 1 status 0x00 bdaddr 00:00:F2:6A:29:69 2011-09-16 18:08:46.764729 > HCI Event: Auth Complete (0x06) plen 3 status 0x00 handle 1 2011-09-16 18:08:46.764821 < ACL data: handle 1 flags 0x00 dlen 12 0000: 08 00 01 00 02 05 04 00 03 00 41 00 ..........A. 2011-09-16 18:08:46.764851 > HCI Event: Command Status (0x0f) plen 4 Unknown (0x00|0x0000) status 0x00 ncmd 2 2011-09-16 18:08:46.768117 > HCI Event: Number of Completed Packets (0x13) plen 5 handle 1 packets 1 2011-09-16 18:08:46.770894 > ACL data: handle 1 flags 0x02 dlen 16 L2CAP(s): Connect rsp: dcid 0x0000 scid 0x0041 result 3 status 0 Connection refused - security block 2011-09-16 18:08:49.000691 < ACL data: handle 1 flags 0x00 dlen 12 0000: 08 00 01 00 06 06 04 00 40 00 40 00 ........@.@. 2011-09-16 18:08:49.015675 > HCI Event: Number of Completed Packets (0x13) plen 5 handle 1 packets 1 2011-09-16 18:08:49.016927 > ACL data: handle 1 flags 0x02 dlen 12 L2CAP(s): Disconn rsp: dcid 0x0040 scid 0x0040 2011-09-16 18:08:51.009480 < HCI Command: Disconnect (0x01|0x0006) plen 3 handle 1 reason 0x13 Reason: Remote User Terminated Connection 2011-09-16 18:08:51.011525 > HCI Event: Command Status (0x0f) plen 4 Disconnect (0x01|0x0006) status 0x00 ncmd 1 2011-09-16 18:08:51.123494 > HCI Event: Disconn Complete (0x05) plen 4 status 0x00 handle 1 reason 0x16 Reason: Connection Terminated by Local Host Signed-off-by: Arek Lichwa <arkadiusz.lichwa@tieto.com> Signed-off-by: Gustavo F.

When comparing two items by IE, the sort order wasn't stable, which could lead to issues in the rbtree. Make it stable by making a missing IE sort before a present IE. Also sort by length first if it differs and then by contents. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

In other modes the parameters should not be set. Right now, mac80211 will set them, even if the user asked for setting them on VLANs which the driver doesn't know about, causing all kinds of trouble.

2011-11-07nl80211: fix HT capability attribute validationJohannes Berg
Since the NL80211_ATTR_HT_CAPABILITY attribute is used as a struct, it needs a minimum, not maximum length. Enforce that properly. Not doing so could potentially lead to reading after the buffer.
