2015-10-07Merge branch 'ovs-ct-fixes'David S. Miller5-30/+50
Joe Stringer says: ==================== OVS conntrack fixes for net The userspace side of the Open vSwitch conntrack changes is currently undergoing review, which has highlighted some minor bugs in the existing conntrack implementation in the kernel, as well as pointing out some future-proofing that can be done on the interface to reduce the need for additional compatibility code in future. The biggest changes here are to the userspace API for the ct_state match field and the CT action. This series proposes to firstly extend the ct_state match field to 32 bits, ensuring to reject any currently unsupported bits. Secondly, rather than representing CT action flags within a 32-bit field, simply use a netlink attribute as presence of the single flag that is defined today. This also serves to reject unsupported ct action flag bits. v4: Use 12-character abbreviated hashes in commit messages. v3: Fully acked. v2: Address minor style feedback, add acks. v1: Initial post. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
2015-10-07openvswitch: Change CT_ATTR_FLAGS to CT_ATTR_COMMITJoe Stringer2-17/+10
Previously, the CT_ATTR_FLAGS attribute, when nested under the OVS_ACTION_ATTR_CT, encoded a 32-bit bitmask of flags that modify the semantics of the ct action. It's more extensible to just represent each flag as a nested attribute, and this requires no additional error checking to reject flags that aren't currently supported.

2015-10-07openvswitch: Extend ct_state match field to 32 bitsJoe Stringer4-11/+11
The ct_state field was initially added as an 8-bit field, however six of the bits are already being used and use cases are already starting to appear that may push the limits of this field. This patch extends the field to 32 bits while retaining the internal representation of 8 bits. This should cover forward compatibility of the ABI for the foreseeable future. This patch also reorders the OVS_CS_F_* bits to be sequential.

2015-10-07openvswitch: Reject ct_state unsupported bitsJoe Stringer2-0/+18
Previously, if userspace specified ct_state bits in the flow key which are currently undefined (and therefore unsupported), then they would be ignored. This could cause unexpected behaviour in future if userspace is extended to support additional bits but attempts to communicate with the current version of the kernel. This patch rectifies the situation by rejecting such ct_state bits.

However, sk_get_filter() wasn't updated to test for this at the time when eBPF could be attached. Just throw an error to the user to indicate that eBPF cannot be dumped over this interface. That way, it can also be known that a program _is_ attached (as opposed to just return 0), and a different (future) method needs to be consulted for a dump.

After commit 1ce87720d456 ("net: sched: make cls_u32 lockless") we began to release tc actions in a RCU callback. However, mirred action relies on RTNL lock to protect the global mirred_list, therefore we could have a race condition between RCU callback and netdevice event, which caused a list corruption as reported by Vinson. Instead of relying on RTNL lock, introduce a spinlock to protect this list. Note, in non-bind case, it is still called with RTNL lock, therefore should disable BH too.

2015-10-05inet: fix race in reqsk_queue_unlink()Eric Dumazet1-9/+10
reqsk_timer_handler() tests if icsk_accept_queue.listen_opt is NULL at its beginning. By the time it calls inet_csk_reqsk_queue_drop() and reqsk_queue_unlink(), listener might have been closed and inet_csk_listen_stop() had called reqsk_queue_yank_acceptq() which sets icsk_accept_queue.listen_opt to NULL We therefore need to correctly check listen_opt being NULL after holding syn_wait_lock for proper synchronization.

2015-10-05net: usb: asix: Fix crash on skb alloc failureDavid B. Robins1-1/+3
If asix_rx_fixup_internal() fails to allocate rx->ax_skb, it will return but not clear rx->size. rx points to driver private data. A later call assumes that nonzero size means ax_skb was allocated and passes a null ax_skb to skb_put. Changed allocation failure return to clear size first.

2015-10-05ppp: don't override sk->sk_state in pppoe_flush_dev()Guillaume Nault1-1/+0
Since commit 2b018d57ff18 ("pppoe: drop PPPOX_ZOMBIEs in pppoe_release"), pppoe_release() calls dev_put(po->pppoe_dev) if sk is in the PPPOX_ZOMBIE state. But pppoe_flush_dev() can set sk->sk_state to PPPOX_ZOMBIE _and_ reset po->pppoe_dev to NULL. This leads to the following oops: [ 570.140800] BUG: unable to handle kernel NULL pointer dereference at 00000000000004e0 [ 570.142931] IP: [<ffffffffa018c701>] pppoe_release+0x50/0x101 [pppoe] [ 570.144601] PGD 3d119067 PUD 3dbc1067 PMD 0 [ 570.144601] Oops: 0000 [#1] SMP [ 570.144601] Modules linked in: l2tp_ppp l2tp_netlink l2tp_core ip6_udp_tunnel udp_tunnel pppoe pppox ppp_generic slhc loop crc32c_intel ghash_clmulni_intel jitterentropy_rng sha256_generic hmac drbg ansi_cprng aesni_intel aes_x86_64 ablk_helper cryptd lrw gf128mul glue_helper acpi_cpufreq evdev serio_raw processor button ext4 crc16 mbcache jbd2 virtio_net virtio_blk virtio_pci virtio_ring virtio [ 570.144601] CPU: 1 PID: 15738 Comm: ppp-apitest Not tainted 4.2.0 #1 [ 570.144601] Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS Debian-1.8.2-1 04/01/2014 [ 570.144601] task: ffff88003d30d600 ti: ffff880036b60000 task.ti: ffff880036b60000 [ 570.144601] RIP: 0010:[<ffffffffa018c701>] [<ffffffffa018c701>] pppoe_release+0x50/0x101 [pppoe] [ 570.144601] RSP: 0018:ffff880036b63e08 EFLAGS: 00010202 [ 570.144601] RAX: 0000000000000000 RBX: ffff880034340000 RCX: 0000000000000206 [ 570.144601] RDX: 0000000000000006 RSI: ffff88003d30dd20 RDI: ffff88003d30dd20 [ 570.144601] RBP: ffff880036b63e28 R08: 0000000000000001 R09: 0000000000000000 [ 570.144601] R10: 00007ffee9b50420 R11: ffff880034340078 R12: ffff8800387ec780 [ 570.144601] R13: ffff8800387ec7b0 R14: ffff88003e222aa0 R15: ffff8800387ec7b0 [ 570.144601] FS: 00007f5672f48700(0000) GS:ffff88003fc80000(0000) knlGS:0000000000000000 [ 570.144601] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 570.144601] CR2: 00000000000004e0 CR3: 0000000037f7e000 CR4: 00000000000406a0 [ 570.144601] Stack: [ 570.144601] ffffffffa018f240 ffff8800387ec780 ffffffffa018f240 ffff8800387ec7b0 [ 570.144601] ffff880036b63e48 ffffffff812caabe ffff880039e4e000 0000000000000008 [ 570.144601] ffff880036b63e58 ffffffff812cabad ffff880036b63ea8 ffffffff811347f5 [ 570.144601] Call Trace: [ 570.144601] [<ffffffff812caabe>] sock_release+0x1a/0x75 [ 570.144601] [<ffffffff812cabad>] sock_close+0xd/0x11 [ 570.144601] [<ffffffff811347f5>] __fput+0xff/0x1a5 [ 570.144601] [<ffffffff811348cb>] ____fput+0x9/0xb [ 570.144601] [<ffffffff81056682>] task_work_run+0x66/0x90 [ 570.144601] [<ffffffff8100189e>] prepare_exit_to_usermode+0x8c/0xa7 [ 570.144601] [<ffffffff81001a26>] syscall_return_slowpath+0x16d/0x19b [ 570.144601] [<ffffffff813babb1>] int_ret_from_sys_call+0x25/0x9f [ 570.144601] Code: 48 8b 83 c8 01 00 00 a8 01 74 12 48 89 df e8 8b 27 14 e1 b8 f7 ff ff ff e9 b7 00 00 00 8a 43 12 a8 0b 74 1c 48 8b 83 a8 04 00 00 <48> 8b 80 e0 04 00 00 65 ff 08 48 c7 83 a8 04 00 00 00 00 00 00 [ 570.144601] RIP [<ffffffffa018c701>] pppoe_release+0x50/0x101 [pppoe] [ 570.144601] RSP <ffff880036b63e08> [ 570.144601] CR2: 00000000000004e0 [ 570.200518] ---[ end trace 46956baf17349563 ]--- pppoe_flush_dev() has no reason to override sk->sk_state with PPPOX_ZOMBIE. pppox_unbind_sock() already sets sk->sk_state to PPPOX_DEAD, which is the correct state given that sk is unbound and po->pppoe_dev is NULL.
