2012-07-19debug: Do not permit CONFIG_DEBUG_STACK_USAGE=y on IA64 or PARISCTony Luck
The stack_not_used() function in <linux/sched.h> assumes that stacks grow downwards. This is not true on IA64 or PARISC, so this function would walk off in the wrong direction and into the weeds. Found on IA64 because of a compilation failure with recursive dependencies on IA64_TASKSIZE and IA64_THREAD_INFO_SIZE. Fixing the code is possible, but should be combined with other infrastructure additions to set up the "canary" at the end of the stack.

2012-07-19ipv4: tcp: remove per net tcp_sockEric Dumazet
tcp_v4_send_reset() and tcp_v4_send_ack() use a single socket per network namespace. This leads to bad behavior on multiqueue NICS, because many cpus contend for the socket lock and once socket lock is acquired, extra false sharing on various socket fields slow down the operations. To better resist to attacks, we use a percpu socket. Each cpu can run without contention, using appropriate memory (local node) Additional features : 1) We also mirror the queue_mapping of the incoming skb, so that answers use the same queue if possible. 2) Setting SOCK_USE_WRITE_QUEUE socket flag speedup sock_wfree() 3) We now limit the number of in-flight RST/ACK [1] packets per cpu, instead of per namespace, and we honor the sysctl_wmem_default limit dynamically. (Prior to this patch, sysctl_wmem_default value was copied at boot time, so any further change would not affect tcp_sock limit) [1] These packets are only generated when no socket was matched for the incoming packet.

Use global seqlock for the nh_exceptions. Call fnhe_oldest with the right hash chain. Correct the diff value for dst_set_expires. v2: after suggestions from Eric Dumazet: * get rid of spin lock fnhe_lock, rearrange update_or_create_fnhe * continue daddr search in rt_bind_exception v3: * remove the daddr check before seqlock in rt_bind_exception * restart lookup in rt_bind_exception on detected seqlock change, as suggested by David Miller Signed-off-by: Julian Anastasov <ja@ssi.bg> Signed-off-by: David S.

2012-07-19net/mlx4_en: Add accelerated RFS supportAmir Vadai
Use RFS infrastructure and flow steering in HW to keep CPU affinity of rx interrupts and application per TCP stream. A flow steering filter is added to the HW whenever the RFS ndo callback is invoked by core networking code. Because the invocation takes place in interrupt context, the actual setup of HW is done using workqueue. Whenever new filter is added, the driver checks for expiry of existing filters. Since there's window in time between the point where the core RFS code invoked the ndo callback, to the point where the HW is configured from the workqueue context, the 2nd, 3rd etc packets from that stream will cause the net core to invoke the callback again and again. To prevent inefficient/double configuration of the HW, the filters are kept in a database which is indexed using hash function to enable fast access.

2012-07-19GFS2: Reduce file fragmentationBob Peterson
This patch reduces GFS2 file fragmentation by pre-reserving blocks. The resulting improved on disk layout greatly speeds up operations in cases which would have resulted in interlaced allocation of blocks previously. A typical example of this is 10 parallel dd processes, each writing to a file in a common dirctory. The implementation uses an rbtree of reservations attached to each resource group (and each inode).
