| | | | | | | | | | | | | | structures in IPX/SPX -- primarily, sequence numbering, PCB lists, and PCBs for IPX raw sockets, IPX datagram sockets, and IPX/SPX. As such, remove remove NET_NEEDS_GIANT() for IPX, and remove the assertion of Giant in the ipxintr() IPX input path. Note that IPX/SPX is not fully MPSAFE, and that there are some problems with IPX/SPX locking that will require some further work. However, it is now safe enough to run in general without the Giant lock. MFC after: 4 weeks
* Use the IPX PCB list mutex and IPX PCB mutexes to lock down the SPXrwatson2005-01-091-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | portion of IPX/SPX: - Protect IPX PCB lists with the IPX PCB list mutex, in particular when calling PCB and PCB list manipulation routines in ipx_pcb.c. - Protect both IPX PCB state and SPX PCB state using the IPX PCB mutex. - Generally annotate locking, as well as adding liberal use of lock assertions to document locking requirements. - Where possible, use unlocked reads when reading integer or smaller sized socket options on SPX sockets. - De-spl throughout. Notes: - spx_input() expects both the list mutex and PCB mutex to be held on entry, but will release both on return. Because sonewconn() is called from spx_input(), it may actually drop one PCB lock and acquire another during generation of a new connection, meaning the caller is not in a position to unlock the PCB mutex.

IF_ENQUEUE, IF_PREPEND, and IF_DEQUEUE perform all necessary locking on the queue. An IF_LOCK macro is provided, as well as the old (mutex-less) versions of the macros in the form _IF_ENQUEUE, _IF_QFULL, for code which needs them, but their use is discouraged. Two new macros are introduced: IF_DRAIN() to drain a queue, and IF_HANDOFF, which takes care of locking/enqueue, and also statistics updating/start if necessary.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | "time" wasn't a atomic variable, so splfoo() protection were needed around any access to it, unless you just wanted the seconds part. Most uses of time.tv_sec now uses the new variable time_second instead. gettime() changed to getmicrotime(0. Remove a couple of unneeded splfoo() protections, the new getmicrotime() is atomic, (until Bruce sets a breakpoint in it). A couple of places needed random data, so use read_random() instead of mucking about with time which isn't random. Add a new nfs_curusec() function. Mark a couple of bogosities involving the now disappeard time variable. Update ffs_update() to avoid the weird "== &time" checks, by fixing the one remaining call that passwd &time as args. Change profiling in ncr.c to use ticks instead of time. Resolution is the same. Add new function "tvtohz()" to avoid the bogus "splfoo(), add time, call hzto() which subtracts time" sequences.

| | | | | | | | | | | | | | | | | | | | | | | | | | Use the MAC address of an interface for the host part of an IPX address and not the MAC address of the first interface for every IPX address. This is more inline with the way others like Novell do it. Mostly Submitted by: "Serge A. Babkin" <babkin@hq.icb.chel.su> Take out the error messages (the ip icmp equivalent) with #ifdef IPXERRORMSGS. This is bogus and as far as I could figure out IPX don't have anything like it. This is a leftover from its XNS heritage. If nobody complains, I will take it out completely in a few weeks. Add some more ipxstat statistics counters. Make ipxprintfs a sysctl variable and off by default. Add IPX Netbios "routing" support. This is off by default and can be switched on with a sysctl knob. General code cleanup to at least use the same style throughout the IPX code, but also be more style(9) conformant. Also make a lot of functions static. If I don't get any complaints I'll bring all of this over to the 2.2 tree in a few weeks.
