2005-08-29[SPARC64]: Eliminate irq_cpustat_t.David S. Miller

2005-08-29[PATCH] Lazy page table copies in fork()Nick Piggin
Defer copying of ptes until fault time when it is possible to reconstruct the pte from backing store. Idea from Andi Kleen and Nick Piggin. Thanks to input from Rik van Riel and Linus and to Hugh for correcting my blundering. Ray Fucillo <fucillo@intersystems.com> reports: "I applied this latest patch to a 2.6.12 kernel and found that it does resolve the problem. Prior to the patch on this machine, I was seeing about 23ms spent in fork for ever 100MB of shared memory segment. After applying the patch, fork is taking about 1ms regardless of the shared memory size." Signed-off-by: Nick Piggin <npiggin@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2005-08-29[CCID3]: Call sk->sk_write_space(sk) when receiving a feedback packetArnaldo Carvalho de Melo
This makes the send rate calculations behave way more closely to what is specified, with the jitter previously seen on x and x_recv disappearing completely on non lossy setups. This resembles the tcp_data_snd_check code, that possibly we'll end up using in DCCP as well, perhaps moving this code to inet_connection_sock. For now I'm doing the simplest implementation tho.

2005-08-29[DCCP]: Introduce DCCP_SOCKOPT_PACKET_SIZEArnaldo Carvalho de Melo
So that applications can set dccp_sock->dccps_pkt_size, that in turn is used in the CCID3 half connection init routines to set ccid3hc[tr]x_s and use it in its rate calculations. Signed-off-by: Arnaldo Carvalho de Melo <acme@mandriva.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2005-08-29[DCCP]: Introduce dccp_tfrc_lib module with net/dccp/ccids/lib/*.cArnaldo Carvalho de Melo
I'll now take a look at the other proposed TFRC DCCP CCIDs to find more code that is now in ccid3.c and move to this module, the loss event rate, calc_X, etc most probably will be moved there. The main goal of these changes is to pave the way for the implementation of more TFRC based DCCP CCIDs and to shrink ccid3.c, reducing its complexity and helping in getting it rock solid.

2005-08-29[CCID3]: Move the loss interval code to loss_interval.[ch]Arnaldo Carvalho de Melo
And put this into net/dccp/ccids/lib/, where packet_history.[ch] will also be moved and then we'll have a tfrc_lib.ko module that will be used by dccp_ccid3.ko and other CCIDs that are variations of TFRC (RFC 3448).

2005-08-29[CCID3]: Reorganise timeval handlingArnaldo Carvalho de Melo
Introducing functions to add to or subtract from a timeval variable and renaming now_delta to timeval_new_delta that calls do_gettimeofday and then timeval_delta, that should be used when there are several deltas made relative to the current time or setting variables to it, so as to avoid calling do_gettimeofday excessively. I'm leaving these "timeval_" prefixed funcions internal to DCCP for a while till we're sure there are no subtle bugs in it. It also is more correct as it checks if the number of usecs added to or subtracted from a tv_usec field is more than 2 seconds.

2005-08-29[DCCP]: Introduce dccp_wait_for_ccid and use it in dccp_write_xmitArnaldo Carvalho de Melo
This is not quite what I think we should have long term but improves performance for now, so lets use it till we get CCID3 working well, then we can think about using sk_write_queue, perhaps using some ideas from Juwen Lai's old stack for 2.4.20.

2005-08-29[NET]: use __read_mostly on kmem_cache_t , DEFINE_SNMP_STAT pointersEric Dumazet
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.

2005-08-29[BNX2]: update version and minor fixesMichael Chan
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.

2005-08-29[BNX2]: remove atomics in txMichael Chan
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: Michael Chan <mchan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2005-08-29[BNX2]: speedup serdes linkupMichael Chan
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: Michael Chan <mchan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2005-08-29[BNX2]: Fix rtnl deadlock in bnx2_closeMichael Chan
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.

2005-08-29[AX25/NETROM]: Cleanup direct calls into IP stackRalf Baechle
Get rid of the calls to ip_rcv and arp_rcv which were layering violations anyway.

2005-08-29[DCCP]: Introduce dccp_get_infoArnaldo Carvalho de Melo
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: Arnaldo Carvalho de Melo <acme@mandriva.com> Signed-off-by: David S.
