* Improved connection establishment performance by doing local port lookups viaDavid Greenman1998-01-271-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | a hashed port list. In the new scheme, in_pcblookup() goes away and is replaced by a new routine, in_pcblookup_local() for doing the local port check. Note that this implementation is space inefficient in that the PCB struct is now too large to fit into 128 bytes. I might deal with this in the future by using the new zone allocator, but I wanted these changes to be extensively tested in their current form first. Also: 1) Fixed off-by-one errors in the port lookup loops in in_pcbbind(). 2) Got rid of some unneeded rehashing. Adding a new routine, in_pcbinshash() to do the initialial hash insertion. 3) Renamed in_pcblookuphash() to in_pcblookup_hash() for easier readability. 4) Added a new routine, in_pcbremlists() to remove the PCB from the various hash lists. 5) Added/deleted comments where appropriate. 6) Removed unnecessary splnet() locking. In general, the PCB functions should be called at splnet()...there are unfortunately a few exceptions, however. 7) Reorganized a few structs for better cache line behavior. 8) Killed my TCP_ACK_HACK kludge. It may come back in a different form in the future, however. These changes have been tested on wcarchive for more than a month. In tests done here, connection establishment overhead is reduced by more than 50 times, thus getting rid of one of the major networking scalability problems. Still to do: make tcp_fastimo/tcp_slowtimo scale well for systems with a large number of connections. tcp_fastimo is easy; tcp_slowtimo is difficult. WARNING: Anything that knows about inpcb and tcpcb structs will have to be recompiled; at the very least, this includes netstat(1). Notes: svn path=/head/; revision=32821

* The long-awaited mega-massive-network-code- cleanup. Part I.Garrett Wollman1997-04-271-21/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | This commit includes the following changes: 1) Old-style (pr_usrreq()) protocols are no longer supported, the compatibility glue for them is deleted, and the kernel will panic on boot if any are compiled in. 2) Certain protocol entry points are modified to take a process structure, so they they can easily tell whether or not it is possible to sleep, and also to access credentials. 3) SS_PRIV is no more, and with it goes the SO_PRIVSTATE setsockopt() call. Protocols should use the process pointer they are now passed. 4) The PF_LOCAL and PF_ROUTE families have been updated to use the new style, as has the `raw' skeleton family. 5) PF_LOCAL sockets now obey the process's umask when creating a socket in the filesystem. As a result, LINT is now broken. I'm hoping that some enterprising hacker with a bit more time will either make the broken bits work (should be easy for netipx) or dike them out.

| | | | | | | | | | | | pr_usrreqs. Collapse duplicates with udp_usrreq.c and tcp_usrreq.c (calling the generic routines in uipc_socket2.c and in_pcb.c). Calling sockaddr()_ or peeraddr() on a detached socket now traps, rather than harmlessly returning an error; this should never happen. Allow the raw IP buffer sizes to be controlled via sysctl.

* Fix the mechanism for choosing wehether to save the slow-start thresholdGarrett Wollman1997-02-141-317/+0

While we're at it: - Convert udp_usrreq from `mondo switch statement from Hell' to new-style. - Delete old TCP mondo switch statement from Hell, which had previously been diked out.

| | | | | | | | | | | This will make a number of things easier in the future, as well as (finally!) avoiding the Id-smashing problem which has plagued developers for so long.

* Modify the kernel to use the new pr_usrreqs interface rather than the oldGarrett Wollman1996-07-111-1/+428
| | | | | | | | | | | | | | | | | 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
