* Prevent the kernel from generating an unaligned sysctl data buffer onAndrew Gallatin2002-01-271-0/+1
| | | | | | | | | | | | 64-bit platforms. The unaligned access is caused by struct ifa_msghdr not being a multiple of 8-bytes in size. If an interface has an odd number of addresses, this causes the next interface to generate an unaligned access in the user-level app walking the interfaces (ifconfig).

* Pull post-4.4BSD change to sys/net/route.c from BSD/OS 4.2.Ruslan Ermilov2001-10-171-21/+14
| | | | | | | | | | | | | | | | | | | | | | | Have sys/net/route.c:rtrequest1(), which takes ``rt_addrinfo *'' as the argument. Pass rt_addrinfo all the way down to rtrequest1 and ifa->ifa_rtrequest. 3rd argument of ifa->ifa_rtrequest is now ``rt_addrinfo *'' instead of ``sockaddr *'' (almost noone is using it anyways). Benefit: the following command now works. Previously we needed two route(8) invocations, "add" then "change". # route add -inet6 default ::1 -ifp gif0 Remove unsafe typecast in rtrequest(), from ``rtentry *'' to ``sockaddr *''.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a seriously beefed up chroot kind of thing. The process is jailed along the same lines as a chroot does it, but with additional tough restrictions imposed on what the superuser can do. For all I know, it is safe to hand over the root bit inside a prison to the customer living in that prison, this is what it was developed for in fact: "real virtual servers". Each prison has an ip number associated with it, which all IP communications will be coerced to use and each prison has its own hostname. Needless to say, you need more RAM this way, but the advantage is that each customer can run their own particular version of apache and not stomp on the toes of their neighbors. It generally does what one would expect, but setting up a jail still takes a little knowledge. A few notes: I have no scripts for setting up a jail, don't ask me for them. The IP number should be an alias on one of the interfaces. mount a /proc in each jail, it will make ps more useable. /proc/<pid>/status tells the hostname of the prison for jailed processes. Quotas are only sensible if you have a mountpoint per prison. There are no privisions for stopping resource-hogging. Some "#ifdef INET" and similar may be missing (send patches!) If somebody wants to take it from here and develop it into more of a "virtual machine" they should be most welcome! Tools, comments, patches & documentation most welcome. Have fun...

* The long-awaited mega-massive-network-code- cleanup. Part I.Garrett Wollman1997-04-271-49/+178
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
