This patch puts mostly read only data in the right section (read_mostly), to help sharing of these data between CPUS without memory ping pongs. On one of my production machine, tcp_statistics was sitting in a heavily modified cache line, so *every* SNMP update had to force a reload. Signed-off-by:

Attached the implementation of the Boyer-Moore string search algorithm for the new textsearch infrastructure. I've added as well a note about the limitations that this approach presents, as Thomas has remarked. Signed-off-by:

Update version and add 4 minor fixes, the last 2 were suggested by Jeff Garzik: 1. check for a valid ethernet address before setting it 2. zero out bp->regview if init_one encounters an error and unmaps the IO address. This prevents remove_one from unmapping again. 3. use netif_rx_schedule() instead of hand coding the same. 4. use IRQ_HANDLED and IRQ_NONE. Signed-off-by:

Change all locks from spin_lock_irqsave() to spin_lock_bh(). All places that require spinlocks are in BH context. Signed-off-by:

Remove atomic operations in the fast tx path. Expensive atomic operations were used to keep track of the number of available tx descriptors. The new code uses the difference between the consumer and producer index to determine the number of free tx descriptors. As suggested by Jeff Garzik, the name of the inline function is changed to all lower case. Signed-off-by:

This speeds up link-up time on 5706 SerDes if the link partner does not autoneg, a rather common scenario in blade servers. Some blade servers use IPMI for keyboard input and it's important to minimize link disruptions. The speedup is achieved by shortening the timer to (HZ / 3) during the transient period right after initiating a SerDes autoneg. If autoneg does not complete, parallel detect can be done sooner. After the transient period is over, the timer goes back to its normal HZ interval. As suggested by Jeff Garzik, the timer initialization is moved to bnx2_init_board() from bnx2_open(). An eeprom bit is also added to allow default forced SerDes speed for even faster link-up time. Signed-off-by:

This fixes an rtnl deadlock problem when flush_scheduled_work() is called from bnx2_close(). In rare cases, linkwatch_event() may be on the workqueue from a previous close of a different device and it will try to get the rtnl lock which is already held by dev_close(). The fix is to set a flag if we are in the reset task which is run from the workqueue. bnx2_close() will loop until the flag is cleared. As suggested by Jeff Garzik, the loop is changed to call msleep(1) instead of yield() in the original patch. flush_scheduled_work() is also moved to bnx2_remove_one() before the netdev is freed.

All these are claiming to include <net/ip.h> to get ip_rcv() but in fact don't need the header at all, so away with the inclusion. Signed-off-by:

Get rid of the calls to ip_rcv and arp_rcv which were layering violations anyway. With those being replaced by netif_rx, less parts of AX.25 and relatives depend on INET support actually being enabled. This also will make PF_PACKET sockets work for IP and ARP packets received over AX.25 and for IP packets over NET/ROM. Signed-off-by:

This is a redo of earlier cleanup stuff: * replace DBG() macro with pr_debug() * get rid of duplicate extern's that are already in fib_lookup.h * use BUG_ON and WARN_ON * don't use BUG checks for null pointers where next statement would get a fault anyway * remove debug printout when rebalance causes deep tree * remove trailing blanks Signed-off-by:

And also hc_tx and hc_rx get_info functions for the CCIDs to fill in information that is specific to them. For now reusing struct tcp_info, later I'll try to figure out a better solution, for now its really nice to get this kind of info: [root@qemu ~]# ./ss -danemi State Recv-Q Send-Q Local Addr:Port Peer Addr:Port LISTEN 0 0 *:5001 *:* ino:628 sk:c1340040 mem:(r0,w0,f0,t0) cwnd:0 ssthresh:0 ESTAB 0 0 172.20.0.2:5001 172.20.0.1:32785 ino:629 sk:c13409a0 mem:(r0,w0,f0,t0) ts rto:1000 rtt:0.004/0 cwnd:0 ssthresh:0 rcv_rtt:61.377 This, for instance, shows that we're not congestion controlling ACKs, as the above output is in the ttcp receiving host, and ttcp is a one way app, i.e. the received never calls sendmsg, so ccid_hc_tx_send_packet is never called, so the TX half connection stays in TFRC_SSTATE_NO_SENT state and hctx_rtt is never calculated, stays with the value set in ccid3_hc_tx_init, 4us, as show above in milliseconds (0.004ms), upcoming patches will fix this. rcv_rtt seems sane tho, matching ping results :-) Signed-off-by: -

So that we retransmit CLOSE/CLOSEREQ packets till they elicit an answer or we hit a timeout. Most of the machinery uses TCP approaches, this code has to be polished & audited, but this is better than we had before. Signed-off-by:
