[DCCP] getsockopt: Fix DCCP_SOCKOPT_[SEND,RECV]_CSCOV

2007-03-28T18:54:32Z

We were only checking if there was enough space to put the int, but left len as specified by the (malicious) user, sigh, fix it by setting len to sizeof(val) and transfering just one int worth of data, the one asked for. Also check for negative len values. Signed-off-by: Arnaldo Carvalho de Melo Signed-off-by: David S. Miller

[DCCP]: make dccp_write_xmit_timer() static again

2007-03-26T01:48:10Z

dccp_write_xmit_timer() needlessly became global. Signed-off-by: Adrian Bunk Signed-off-by: David S. Miller

[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).

[DCCP]: Revert patch which disables bidirectional mode

2007-03-08T00:08:07Z

This reverts an earlier patch which disabled bidirectional mode, meaning that a listening (passive) socket was not allowed to write to the other (active) end of the connection. This mode had been disabled when there were problems with CCID3, but it imposes a constraint on socket programming and thus hinders deployment. A change is included to ignore RX feedback received by the TX CCID3 module. Many thanks to Andre Noll for pointing out this issue. Signed-off-by: Gerrit Renker Signed-off-by: David S. Miller

[DCCP]: Set RTO for newly created child socket

2007-03-06T22:24:44Z

This mirrors a recent change in tcp_open_req_child, whereby the icsk_rto of the newly created child socket was not set (but rather on the parent socket). Same fix for DCCP. Signed-off-by: Gerrit Renker Signed-off-by: Arnaldo Carvalho de Melo Signed-off-by: David S. Miller

[DCCP]: Correctly split CCID half connections

2007-03-06T22:24:18Z

This fixes a bug caused by a previous patch, which causes DCCP servers in LISTEN state to not receive packets. This patch changes the logic so that * servers in either LISTEN or OPEN state get the RX half connection packets * clients in OPEN state get the TX half connection packets Signed-off-by: Gerrit Renker Signed-off-by: Arnaldo Carvalho de Melo Signed-off-by: David S.

[PATCH] sysctl: remove insert_at_head from register_sysctl

2007-02-14T16:09:59Z

The semantic effect of insert_at_head is that it would allow new registered sysctl entries to override existing sysctl entries of the same name. Which is pain for caching and the proc interface never implemented. I have done an audit and discovered that none of the current users of register_sysctl care as (excpet for directories) they do not register duplicate sysctl entries. So this patch simply removes the support for overriding existing entries in the sys_sysctl interface since no one uses it or cares and it makes future enhancments harder. Signed-off-by: Eric W.

[PATCH] mark struct file_operations const 7

2007-02-12T17:48:46Z

Many struct file_operations in the kernel can be "const". Marking them const moves these to the .rodata section, which avoids false sharing with potential dirty data. In addition it'll catch accidental writes at compile time to these shared resources. Signed-off-by: Arjan van de Ven Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds
