2001-06-15Avoid a dangerous race.Artur Grabowski
To avoid having a ptrace(2)d process from doing an exec of a suid binary we strip off the suid bits from the executable if the process is traced. Later we P_SUGID{,EXEC} in the process flags that stops further ptrace attempts. The problem is that between the stripping of suid bits and setting P_SUGID{,EXEC} there is a pretty large window where the process can sleep and other processes can attach to it with ptrace. This is a quick fix for that. We set P_SUGID{,EXEC} early and take care to remove them (we don't want the process to become tainted unnecessarily) if exec fails. XXX - exec needs a lot more work, but people are asking for a solution now.

2001-05-28cluster_rbuild() have a race between incore and getblk. incore() returnsGrigoriy Orlov
zero indicating that buffer is not in a cache, but getblk() going to sleep: getblk->getnewbuf->tsleep. When getnewbuf() returns after a sleep, getblk() may find B_DONE buffer in hash and return it. When io operation finishes biodone() calls cluster_callback() which moves pages from one big cluster buffer into several component buffers and calls biodone() for every component buffer. Since there are a component buffer with B_DONE already set, biodone() panices: "biodone already". costa@ ok.

2001-05-26Sync in some improvements from FreeBSD + my own improvements.Artur Grabowski
- use pool for allocating pipe structures. - use microtime instead of splhigh and time. - improve locking. - better handling of nonblocking. - various efficiency fixes.

it is to be friendly with postfix daemon-to-daemon communication (not 100% sure if which behavior is correct, specwise). patch similar to netbsd.

2001-05-18Use pool_page_alloc_nointr() and pool_page_free_nointr() since theyTodd C. Miller
are exported wheras pool_page_alloc() and pool_page_free() are static. In the non-UVM case these just call pool_page_alloc() and pool_page_free() anyway.

2001-05-16Introduce a new kernel option "SMALL_KERNEL" that will be used to keep theArtur Grabowski
kernel size down. Two changes. Uninline MALLOC and uninline a few mbuf macros. Saves 140k on alpha RAMDISK (although only 11k after gzip).
2001-05-16kill COMPAT_{09,10,11} kernel options. We still need kern_info_09.c and ↵Todd C. Miller
kern_ipc_10.c for other compat modules.
