* Modify the kernel to use the new pr_usrreqs interface rather than the oldGarrett Wollman1996-07-111-4/+16
| | | | | | | | | | | | | | | | | pr_usrreq mechanism which was poorly designed and error-prone. This commit renames pr_usrreq to pr_ousrreq so that old code which depended on it would break in an obvious manner. This commit also implements the new interface for TCP, although the old function is left as an example (#ifdef'ed out). This commit ALSO fixes a longstanding bug in the TCP timer processing (introduced by davidg on 1995/04/12) which caused timer processing on a TCB to always stop after a single timer had expired (because it misinterpreted the return value from tcp_usrreq() to indicate that the TCB had been deleted). Finally, some code related to polling has been deleted from if.c because it is not relevant t -current and doesn't look at all like my current code. Notes: svn path=/head/; revision=17096
* Fix a bug in the handling of the "persist" state which, under certainJohn Polstra1996-06-031-7/+12
| | | | | | | | | | | | | circumstances, caused perfectly good connections to be dropped. This happened for connections over a LAN, where the retransmit timer calculation TCP_REXMTVAL(tp) returned 0. If sending was blocked by flow control for long enough, the old code dropped the connection, even though timely replies were being received for all window probes. Reviewed by: W. Richard Stevens <rstevens@noao.edu> Notes: svn path=/head/; revision=16099
* Two fixes from Rich Stevens:David Greenman1996-04-151-2/+2
| | | | | | | | | | | | 1) Set the persist timer to help time-out connections in the CLOSING state. 2) Honor the keep-alive timer in the CLOSING state. This fixes problems with connections getting "stuck" due to incompletion of the final connection shutdown which can be a BIG problem on busy WWW servers. Notes: svn path=/head/; revision=15262
