As some driver authors seem to reintroduce dev->last_rx use, add a comment to strongly discourage this. Since commit 6cf3f41e (bonding, net: Move last_rx update into bonding recv logic), network drivers dont need to update last_rx themselves, unless they use this field to implement a timeout. Not updating last_rx helps not dirtying a cache line, improving performance in SMP. Signed-off-by:

This updates the use of larger initial windows, as originally specified in RFC 3390, to use the newer IW values specified in RFC 5681, section 3.1. The changes made in RFC 5681 are: a) the setting now is more clearly specified in units of segments (as the comments by John Heffner emphasized, this was not very clear in RFC 3390); b) for connections with 1095 < SMSS <= 2190 there is now a change: - RFC 3390 says that IW <= 4380, - RFC 5681 says that IW = 3 * SMSS <= 6570. Since RFC 3390 is older and "only" proposed standard, whereas the newer RFC 5681 is already draft standard, it seems preferable to use the newer IW variant.

This makes RTAX_RTO_MIN also available to CCID-3, replacing the compile-time RTO lower bound with a per-route tunable value. The original Kconfig option solved the problem that a very low RTT (in the order of HZ) can trigger too frequent and unnecessary reductions of the sending rate. This tunable does not affect the initial RTO value of 2 seconds specified in RFC 5348, section 4.2 and Appendix B. But like the hardcoded Kconfig value, it allows to adapt to network conditions. The same effect as the original Kconfig option of 100ms is now achieved by > ip route replace to unicast 192.168.0.0/24 rto_min 100j dev eth0 (assuming HZ=1000). Signed-off-by:

Using a fixed RTO_MIN of 0.2 seconds was found to cause problems for CCID-2 over 802.11g: at least once per session there was a spurious timeout. It helped to then increase the the value of RTO_MIN over this link. Since the problem is the same as in TCP, this patch makes the solution from commit "05bb1fad" "[TCP]: Allow minimum RTO to be configurable via routing metrics." available to DCCP. This avoids reinventing the wheel, so that e.g. the following works in the expected way now also for CCID-2: > ip route change 10.0.0.2 rto_min 800 dev ath0 Luckily this useful rto_min function was recently moved to net/tcp.h, which simplifies sharing code originating from TCP. Documentation also updated (plus minor whitespace fixes). Signed-off-by:

This patch consolidates initial-window code common to TCP and CCID-2: * TCP uses RFC 3390 in a packet-oriented manner (tcp_input.c) and * CCID-2 uses RFC 3390 in packet-oriented manner (RFC 4341). Signed-off-by:

This removes the wrappers around the sk timer functions, since not much is gained from using them: the BUG_ON in start_rto_timer will never trigger since that function is called only if: * the RTO timer expires (rto_expire, and then timer_pending() is false); * in tx_packet_sent only if !timer_pending() (BUG_ON is redundant here); * previously in new_ack, after stopping the timer (timer_pending() false). Removing the wrappers also clears the way for eventually replacing the RTO timer with the icsk-retransmission-timer, as it is already part of the DCCP socket. Signed-off-by:

Since CCID-2 is de facto a mini implementation of TCP, it makes sense to share as much code as possible. Hence this patch aligns CCID-2 timestamping with TCP timestamping. This also halves the space consumption (on 64-bit systems). The necessary include file <net/tcp.h> is already included by way of net/dccp.h. Redundant includes have been removed. Signed-off-by:

This patch provides a "user timeout" support as described in RFC793. The socket option is also needed for the the local half of RFC5482 "TCP User Timeout Option". TCP_USER_TIMEOUT is a TCP level socket option that takes an unsigned int, when > 0, to specify the maximum amount of time in ms that transmitted data may remain unacknowledged before TCP will forcefully close the corresponding connection and return ETIMEDOUT to the application. If 0 is given, TCP will continue to use the system default. Increasing the user timeouts allows a TCP connection to survive extended periods without end-to-end connectivity. Decreasing the user timeouts allows applications to "fail fast" if so desired. Otherwise it may take upto 20 minutes with the current system defaults in a normal WAN environment. The socket option can be made during any state of a TCP connection, but is only effective during the synchronized states of a connection (ESTABLISHED, FIN-WAIT-1, FIN-WAIT-2, CLOSE-WAIT, CLOSING, or LAST-ACK). Moreover, when used with the TCP keepalive (SO_KEEPALIVE) option, TCP_USER_TIMEOUT will overtake keepalive to determine when to close a connection due to keepalive failure. The option does not change in anyway when TCP retransmits a packet, nor when a keepalive probe will be sent. This option, like many others, will be inherited by an acceptor from its listener.

Replace loops calling set_bit() and clear_bit() with bitmap_set() and bitmap_clear(). Unlike loops calling set_bit() and clear_bit(), bitmap_set() and bitmap_clear() are not atomic. But this is ok. Because the bitmap operations are protected by bitmap->lock except for initialization of the bitmap in mlx4_bitmap_init(). Signed-off-by:

compare_ether_header() can have a special implementation on 64 bit arches if CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS is defined. __napi_gro_receive() and vlan_gro_common() can avoid a conditional branch to perform device match. On x86_64, __napi_gro_receive() has now 38 instructions instead of 53 As gcc-4.4.3 still choose to not inline it, add inline keyword to this performance critical function. Signed-off-by:
