dccp: Allow to distinguish original and retransmitted packets

2008-07-26T10:59:09Z

This patch allows the sender to distinguish original and retransmitted packets, which is in particular needed for the retransmission of DCCP-Requests: * the first Request uses ISS (generated in net/dccp/ip*.c), and sets GSS = ISS; * all retransmitted Requests use GSS' = GSS + 1, so that the n-th retransmitted Request has sequence number ISS + n (mod 48). To add generic support, the patch reorganises existing code so that: * icsk_retransmits == 0 for the original packet and * icsk_retransmits = n > 0 for the n-th retransmitted packet at the time dccp_transmit_skb() is called, via dccp_retransmit_skb(). Thanks to Wei Yongjun for pointing this problem out. Further changes: ---------------- * removed the `skb' argument from dccp_retransmit_skb(), since sk_send_head is used for all retransmissions (the exception is client-Acks in PARTOPEN state, but these do not use sk_send_head); * since sk_send_head always contains the original skb (via dccp_entail()), skb_cloned() never evaluated to true and thus pskb_copy() was never used.

net: convert BUG_TRAP to generic WARN_ON

2008-07-26T04:43:18Z

Removes legacy reinvent-the-wheel type thing. The generic machinery integrates much better to automated debugging aids such as kerneloops.org (and others), and is unambiguous due to better naming. Non-intuively BUG_TRAP() is actually equal to WARN_ON() rather than BUG_ON() though some might actually be promoted to BUG_ON() but I left that to future. I could make at least one BUILD_BUG_ON conversion. Signed-off-by: Ilpo Järvinen Signed-off-by: David S. Miller

[NET]: Convert init_timer into setup_timer

2008-01-28T22:53:35Z

Many-many code in the kernel initialized the timer->function and timer->data together with calling init_timer(timer). There is already a helper for this. Use it for networking code. The patch is HUGE, but makes the code 130 lines shorter (98 insertions(+), 228 deletions(-)). Signed-off-by: Pavel Emelyanov Acked-by: Arnaldo Carvalho de Melo Signed-off-by: David S. Miller

[DCCP]: Provide 10s of microsecond timesource

2007-10-10T23:52:35Z

This provides a timesource, conveniently used for DCCP timestamps, which returns the elapsed time in 10s of microseconds since initialisation. This makes for a wrap-around time of about 11.9 hours, which should be sufficient for most applications. Signed-off-by: Gerrit Renker Signed-off-by: Arnaldo Carvalho de Melo Signed-off-by: David S.

[DCCP]: Initialise write_xmit_timer also on passive sockets

2007-03-09T21:47:58Z

The TX CCID needs the write_xmit_timer for delaying packet sends. Previously this timer was only activated on active (connecting) sockets. This patch initialises the write_xmit_timer in sync with the other timers, i.e. the timer will be ready on any socket. This is used by applications with a listening socket which start to stream after receiving an initiation by the client. The write_xmit_timer is stopped when the application closes, as before. Was tested to work and to remove the timer bug reported on dccp@vger. Also moved timer initialisation into timer.c (static).
