2012-06-12Bluetooth: Update HCI timeouts constants to use msecs_to_jiffiesAndrei Emeltchenko
The HCI constants are always used in form of jiffies. So just include the conversion from msecs in the define itself.

2012-06-11inet: Add family scope inetpeer flushes.David S. Miller
This implementation can deal with having many inetpeer roots, which is a necessary prerequisite for per-FIB table rooted peer tables. Each family (AF_INET, AF_INET6) has a sequence number which we bump when we get a family invalidation request. Each peer lookup cheaply checks whether the flush sequence of the root we are using is out of date, and if so flushes it and updates the sequence number. Signed-off-by: David S. Miller <davem@davemloft.net>
2012-06-11ipv4: Kill ip_rt_frag_needed().David S. Miller
There is zero point to this function. It's only real substance is to perform an extremely outdated BSD4.2 ICMP check, which we can safely remove. If you really have a MTU limited link being routed by a BSD4.2 derived system, here's a nickel go buy yourself a real router. The other actions of ip_rt_frag_needed(), checking and conditionally updating the peer, are done by the per-protocol handlers of the ICMP event. TCP, UDP, et al. have a handler which will receive this event and transmit it back into the associated route via dst_ops->update_pmtu(). This simplification is important, because it eliminates the one place where we do not have a proper route context in which to make an inetpeer lookup. Signed-off-by: David S. Miller <davem@davemloft.net>
2012-06-11inet: Hide route peer accesses behind helpers.David S. Miller
We encode the pointer(s) into an unsigned long with one state bit. The state bit is used so we can store the inetpeer tree root to use when resolving the peer later. Later the peer roots will be per-FIB table, and this change works to facilitate that. Signed-off-by: David S. Miller <davem@davemloft.net>

2012-06-09[PATCH] tcp: Cache inetpeer in timewait socket, and only when necessary.David S. Miller
Since it's guarenteed that we will access the inetpeer if we're trying to do timewait recycling and TCP options were enabled on the connection, just cache the peer in the timewait socket. In the future, inetpeer lookups will be context dependent (per routing realm), and this helps facilitate that as well. Signed-off-by: David S. Miller <davem@davemloft.net>

2012-06-09tcp: Get rid of inetpeer special cases.David S. Miller
The get_peer method TCP uses is full of special cases that make no sense accommodating, and it also gets in the way of doing more reasonable things here. First of all, if the socket doesn't have a usable cached route, there is no sense in trying to optimize timewait recycling. Likewise for the case where we have IP options, such as SRR enabled, that make the IP header destination address (and thus the destination address of the route key) differ from that of the connection's destination address. Just return a NULL peer in these cases, and thus we're also able to get rid of the clumsy inetpeer release logic. Signed-off-by: David S. Miller <davem@davemloft.net>
2012-06-08inet: Create and use rt{,6}_get_peer_create().David S. Miller

2012-06-08af_unix: speedup /proc/net/unixEric Dumazet
/proc/net/unix has quadratic behavior, and can hold unix_table_lock for a while if high number of unix sockets are alive. (90 ms for 200k sockets...) We already have a hash table, so its quite easy to use it. Problem is unbound sockets are still hashed in a single hash slot (unix_socket_table[UNIX_HASH_TABLE]) This patch also spreads unbound sockets to 256 hash slots, to speedup both /proc/net/unix and unix_diag. Time to read /proc/net/unix with 200k unix sockets : (time dd if=/proc/net/unix of=/dev/null bs=4k) before : 520 secs after : 2 secs Signed-off-by: Eric Dumazet <edumazet@google.com> Cc: Steven Whitehouse <swhiteho@redhat.com> Cc: Pavel Emelyanov <xemul@parallels.com> Signed-off-by: David S.

2012-06-08Bluetooth: Fix deadlock and crash when SMP pairing times outJohan Hedberg
The l2cap_conn_del function tries to cancel_sync the security timer, but when it's called from the timeout function itself a deadlock occurs. Subsequently the "hcon->l2cap_data = NULL" that's supposed to protect multiple calls to l2cap_conn_del never gets cleared and when the connection finally drops we double free's etc which will crash the kernel. This patch fixes the issue by using the HCI_CONN_LE_SMP_PEND for protecting against this. The same flag is also used for the same purpose in other places in the SMP code.
