* bridge: Fix potential deadlock on br->multicast_lockAndrey Vagin2011-11-141-2/+2
| | | | | | | | | | | | | | | | | multicast_lock is taken in softirq context, so we should use spin_lock_bh() in userspace. call-chain in softirq context: run_timer_softirq() br_multicast_query_expired() call-chain in userspace: sysfs_write_file() store_multicast_snooping() br_multicast_toggle() Signed-off-by: Andrew Vagin <avagin@openvz.org> Signed-off-by: David S.

* ip6_tunnel: copy parms.name after register_netdeviceJosh Boyer2011-11-141-1/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* rds: drop "select LLIST"Paul Bolle2011-11-141-1/+0
| | | | | | | | | | | | | Commit 1bc144b625 ("net, rds, Replace xlist in net/rds/xlist.h with llist") added "select LLIST" to the RDS_RDMA Kconfig entry. But there is no Kconfig symbol named LLIST. The select statement for that symbol is a nop. Drop it. lib/llist.o is builtin, so all that's needed to use the llist functionality is to include linux/llist.h, which this commit also did.

* net/packet: remove dead code and unneeded variable from ↵Jesper Juhl2011-11-141-4/+2
| | | | | | | | | | | | prb_setup_retire_blk_timer() We test for 'tx_ring' being != zero and BUG() if that's the case. So after that check there is no way that 'tx_ring' could be anything _but_ zero, so testing it again is just dead code. Once that dead code is removed, the 'pkc' local variable becomes entirely redundant, so remove that as well. Signed-off-by: Jesper Juhl <jj@chaosbits.net> Signed-off-by: David S.

* ah: Don't return NET_XMIT_DROP on input.Nick Bowler2011-11-122-4/+0
| | | | | | | | | | | | 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. Signed-off-by: Nick Bowler <nbowler@elliptictech.com> Signed-off-by: David S. Miller <davem@davemloft.net>

| | | * Bluetooth: Use miliseconds for L2CAP channel timeoutsAndrzej Kaczmarek2011-11-071-8/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Timers set by __set_chan_timer() should use miliseconds instead of jiffies. Commit 942ecc9c4643db5ce071562e0a23f99464d6b461 updated l2cap_set_timer() so it expects timeout to be specified in msecs instead of jiffies. This makes timeouts unreliable when CONFIG_HZ is not set to 1000. Signed-off-by: Andrzej Kaczmarek <andrzej.kaczmarek@tieto.com> Signed-off-by: Gustavo F. Padovan <padovan@profusion.mobi>

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. Correct this issue by simply passing the error code unadulterated. Signed-off-by: Nick Bowler <nbowler@elliptictech.com> Signed-off-by: David S. Miller <davem@davemloft.net>

It looks like I get two HCI reset command complete events (see hcidump logs below). The root cause is reset called from off_timer. Timeout for this reset to complete is set to 250ms and my bt dongle requires more time for replying with command complete event. After that, chip seems to reply with reset command complete event for next non-reset command. Attached patch increase mentioned timeout to HCI_INIT_TIMEOUT, this value is already used for timeouting hci_reset_req in hci_dev_reset(). This might also be related to BT not working after suspend that was reported here some time ago.

For such services we will create rpcbind clients and remove all stale portmap registrations. Also, svc_rpcb_cleanup() will be set as sv_shutdown callback for such services in case of this field wasn't initialized earlier. This will allow to destroy rpcbind clients when no other users of them left. Note: Currently, any creating service will be detected as portmap user. Probably, this is wrong.

However unx_match allows a match when the cached credential has extra groups at the end of uc_gids list which are not in the process group list. So if a process with a list of (say) 4 group accesses a file and gains access because of the last group in the list, then another process with the same uid and gid, and a gid list being the first tree of the gids of the original process tries to access the file, it will be granted access even though it shouldn't as the wrong rpc credential will be used.
