| * net: The world is not perfect patch.Rami Rosen2008-05-213-362/+3
| | | | | | | | | | | | | | | | | | | | | | | | Unless there will be any objection here, I suggest consider the following patch which simply removes the code for the -DI_WISH_WORLD_WERE_PERFECT in the three methods which use it. The compilation errors we get when using -DI_WISH_WORLD_WERE_PERFECT show that this code was not built and not used for really a long time.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Here the local hexbuf is a duplicate of global const char hex_asc from lib/hexdump.c, except the hex letters' cases: const char hexbuf[] = "0123456789ABCDEF"; const char hex_asc[] = "0123456789abcdef"; and here to print HW addresses, the hex cases are not significant.

| * tcp: TCP connection times out if ICMP frag needed is delayedSridhar Samudrala2008-05-211-4/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We are seeing an issue with TCP in handling an ICMP frag needed message that is received after net.ipv4.tcp_retries1 retransmits. The default value of retries1 is 3. So if the path mtu changes and ICMP frag needed is lost for the first 3 retransmits or if it gets delayed until 3 retransmits are done, TCP doesn't update MSS correctly and continues to retransmit the orginal message until it timesout after tcp_retries2 retransmits. I am seeing this issue even with the latest 2.6.25.4 kernel. In tcp_retransmit_timer(), when retransmits counter exceeds tcp_retries1 value, the dst cache entry of the socket is reset. At this time, if we receive an ICMP frag needed message, the dst entry gets updated with the new MTU, but the TCP sockets dst_cache entry remains NULL. So the next time when we try to retransmit after the ICMP frag needed is received, tcp_retransmit_skb() gets called. Here the cur_mss value is calculated at the start of the routine with a NULL sk_dst_cache. Instead we should call tcp_current_mss after the rebuild_header that caches the dst entry with the updated mtu. Also the rebuild_header should be called before tcp_fragment so that skb is fragmented if the mss goes down. Signed-off-by: Sridhar Samudrala <sri@us.ibm.com> Signed-off-by: David S.

There are two principal pieces of data that need to be tracked: the list of pages that comprise the completed RPC and the SGE of dma mapped pages to refer to this list of pages. Previously this whole bit was managed as a linked list of contexts with the context containing the page list buried in this list. This patch simplifies this processing by not keeping a linked list, but rather only a pionter from the last submitted RDMA_READ's context to the context that maps the set of pages that describe the RPC. This significantly simplifies this code path. SGE contexts are cleaned up inline in the DTO path instead of at read completion time. Signed-off-by: Tom Tucker <tom@opengridcomputing.com>

This reference is supposed to be removed when the DISCONNECT event is received, however, the call to svc_xprt_put was missing in the switch statement.

This function races with the dto_tasklet that also reaps SQ WR. To avoid polling and arming the CQ unnecessarily move the test_and_clear_bit of the RDMAXPRT_SQ_PENDING flag and arming of the CQ to the sq_cq_reap function. Refactor the rq_cq_reap function to match sq_cq_reap so that the code is easier to follow. Signed-off-by: Tom Tucker <tom@opengridcomputing.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The svcrdma transport provider currently allocates receive buffers to the RQ through the xpo_release_rqst method. This approach is overly complicated since it means that the rqstp rq_xprt_ctxt has to be selectively set based on whether the RPC is going to be processed immediately or deferred. Instead, just post the receive buffer when we are certain that we are replying in the send_reply function. Signed-off-by: Tom Tucker <tom@opengridcomputing.com>

| | |/ | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Because the IPsec output function xfrm_output_resume does its own dst_output call it should always call __ip_local_output instead of ip_local_output as the latter may invoke dst_output directly. Otherwise the return values from nf_hook and dst_output may clash as they both use the value 1 but for different purposes. When that clash occurs this can cause a packet to be used after it has been freed which usually leads to a crash. Because the offending value is only returned from dst_output with qdiscs such as HTB, this bug is normally not visible. Thanks to Marco Berizzi for his perseverance in tracking this down.

| | | | | | | | | | | | | | | | | | | | | | | | | | | We could not see appropriate lifetime if the route had been scheduled to expired at 0 (in jiffies). We should check rt6i_flags instead of rt6i_expires to determine whether lifetime is valid or not. Signed-off-by: YOSHIFUJI Hideaki <yoshfuji@linux-ipv6.org> Signed-off-by: David S.

| | * | mac80211: Add RTNL version of ieee80211_iterate_active_interfacesIvo van Doorn2008-05-161-1/+36

This patch restores ieee80211_iterate_active_interfaces() to use RTNL lock, and provides the non-RTNL version under a new name: ieee80211_iterate_active_interfaces_atomic() So far only rt2x00 uses ieee80211_iterate_active_interfaces(), and those drivers require the RTNL version of ieee80211_iterate_active_interfaces(). Since they already call that function directly, this patch will automatically fix the USB rt2x00 drivers. v2: Rename ieee80211_iterate_active_interfaces_rtnl Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Acked-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes the association problem with 11n hidden ssid ap. Patch fixes the problem of associating with hidden ssid when all three parameters ap,essid and channel are given to iwconfig. This patch removes the condition of checking three parameters and always checks for bss in bss list while associating.
