* various tweaks; my apologies to itojun for forgetting tojmc2006-12-091-26/+28
| | | | send him feedback for these
* switch IPv6 advanced API from RFC2292 to RFC3542 (2292 is superseded by 3542).itojun2006-12-097-5/+971
| | | | | | | | | | the kernel still handles RFC2292 set/getsockopts, so that compiled binary has no trouble running. userland sees RFC3542 symbols only on header file so new code has to use RFC3542 API. bump libc shlib minor for function additions. tested on i386/amd64 by jmc, i386 by brad. checked by deraadt.

* respond to ben hawkes's ruxcon presentation.tedu2006-10-241-61/+125
| | | | | | | | | | | | | create special allocators for pginfo and pgfree structs instead of imalloc. this keeps them separated from application memory. for chunks, to prevent deterministic reuse, keep a small array and swizzle the to be freed chunk with a random previously freed chunk. this last bit only for chunks because keeping arbitrarily large regions of pages around may cause out of memory issues (and pages are, to some extent, returned in random order). all changes enabled by default. thanks to ben for pointing out these issues. ok tech@

* Part 2 of file descriptor race and deadlock corrections.kurt2006-09-261-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Adjust design of file descriptor table to eliminate races with both opening and closing of file descriptor entries and eliminates one class of deadlocks. One nice side effect of this change in design should be better performance for applications that open and close many file descriptors due to reduced fd_table_lock contention and fd entry reuse. - Add entry states to manage use of entry and eliminate some closing races. fd entries are not deallocated upon close() now. - Call _thread_fd_table_init with one of five discreet modes to properly initialize an entry and manage the state transition to open. - When closing an entry hold the entry spinlock locked across the state transition and the _thread_sys_close call to close another race. - Introduce a new lock type FD_RDWR_CLOSE that transitions either a closed entry or an open entry into closing state and then waits for a RDWR lock so that the lock queue can unwind normally. All subsequent fd lock attempts for that entry are rejected with EBADF until the fd is fully closed, or reopened by dup2(). Once a thread holds the FD_RDWR_LOCK it is safe to close() it or dup2() on it. - When a thread creates a new fd there is a window of time when another thread could attempt to use the fd before the creating thread has initialized the entry for it. This can result in improper status_flags for the entry, so record the entries init mode, detect when this has happened and correct the status_flags when needed. reviewed by marc@ & brad@, tested by several, okay brad@

* Back out change in rev 1.15 of to allow whitespace to separate amillert2006-09-221-10/+1
| | | | | | | | | flag from its optional argument if permutation is disabled. The idea was that since "r:" would match "-r foo" then "r::" should match "-r foo" too as long as we know that things have not been reshuffled. Unfortunately, this causes incompatibilities with GNU getopt_long when the POSIXLY_CORRECT environment variable is set. OK deraadt@
