2004-05-14use pool for namei pathbuf. testing ok millert@ tdeval@Ted Unangst
2004-05-10when doing user mounts, inherit the MNT_NOEXEC flag from the coveredPedro Martelletto
vnode's mount point. this makes it impossible for a user to bypass the noexec protection of a mount point by null-mounting it on top of itself. ok tedu@ millert@

2004-05-03POSIX says the length parameter for semop(2) and shmget(2) should be size_t.Todd C. Miller
Create new syscalls with the correct parameters and add compat versions for the old ones under COMPAT_35.

2004-04-25radix tree with multipath support. from kame. deraadt okJun-ichiro itojun Hagino
user visible changes: - you can add multiple routes with same key (route add A B then route add A C) - you have to specify gateway address if there are multiple entries on the table (route delete A B, instead of route delete A) kernel change: - radix_node_head has an extra entry - rnh_deladdr takes extra argument TODO: - actually take advantage of multipath (rtalloc -> rtalloc_mpath)
2004-04-19introduce a new km_page allocator that gets pages from kernel_map usingTed Unangst
an interrupt safe thread. use this as the new backend for mbpool and mclpool, eliminating the mb_map. introduce a sysctl kern.maxclusters which controls the limit of clusters allocated. testing by many people, works everywhere but m68k. ok deraadt@ this essentially deprecates the NMBCLUSTERS option, don't use it. this should reduce pressure on the kmem_map and the uvm reserve of static map entries.
2004-04-19also use sbcheckreserve() for setsockopt of SO_SNDBUF and SO_RCVBUFTheo de Raadt
2004-04-19this is only a work in progress, we can perfect afterwards, but it is timeTheo de Raadt
to get some experience with these ideas. add sbcheckreserve() api; called by accepting sockets. if over 95% of mbuf clusters are busy, consider this a resource starvation just like the other reasons for accept failing. also, if over 50% of mbuf clusters are busy, shrink recv & send sockbuf reserves to "the minimum".
2004-04-17Don't forget to apply the M_CLUSTER flag when copying flags in m_pullup2().Ryan Thomas McBride
Fixes pr3740. Confirmed with pb@, ok markus@.

2004-04-15rework access to emulations slightly in an effort to both merge andTed Unangst
separate exec format from emulation. consistent naming of freebsd emuls. not much in the way of functional changes yet. testing and ok deraadt@ and others along the way.

2004-04-11Crank max ptys to 992. We now have 62 pty/tty pairs for each letterTodd C. Miller
instead of 16. E.g. it is now /dev/{p,t}typ[0-9a-zA-z] instead of just /dev/{p,t}typ[0-9a-f]. This requires that you update MAKEDEV and run: # cd /dev && ./MAKEDEV pty0 && rm -f [pt]ty[rq]*
2004-04-11Fix calculation of the index into TTY_LETTERS. This only workedTodd C. Miller

2004-02-10Fix off-by-one wrt TTY_LETTERS and minor being out of bounds. MissedTodd C. Miller
when I fixed the other TTY_LETTERS/TTY_SUFFIX off-by-ones.
2004-02-10Add the ptm device to pty(4). By opening /dev/ptm and using the PTMGETTodd C. Miller
ioctl(2), an unprivileged process may allocate a pty and have its owner and mode set appropriately. This means that programs such as xterm and screen no longer need to be setuid. Programs using the openpty() function require zero changes and will "just work". Designed by beck@ and deraadt@; changes by beck@ with cleanup (and a rewrite of the vnode bits) by art@ and tweaks/bugfixes by me. Tested by many.
