* Improve the libc DNS resolver ID generation algorithm to be moredjm2008-04-131-43/+79
| | | | | | | resistant to prediction atacks by wrapping the existing LCG in a random permutation generator based on a Luby-Rackoff block cipher. lots of discussion and final ok deraadt@
* Use arc4random_buf() when requesting more than a single word of outputdjm2008-04-131-2/+2

| | | | | | calls vfork(2). "untested, but looks OK" marc@ - document vfork(2), popen(3) and system(3) don't call atfork handlers in multithreaded programs. okay jmc@

| | | | | | | | Instead, just return 1 if there is a difference. Found by lint. OK millert.

* diff from djm@ committed at his request:otto2008-03-162-3/+84
| | | | | | | | | | | | | | introduce two new APIs for requesting strong random numbers: arc4random_buf() - fill an arbitrary memory range with random numbers arc4random_uniform() - return a uniformly distributed random number below a specified upper bound, avoiding the bias that comes from a naive "arc4random() % upper_bound" construction. these mirror similarly-named functions in the kernel; lots of discussion deraadt@ mcbride@
* - len is size_t, but n uses len and is an int. Matching those typesray2008-03-151-6/+12
| | | | | | | | | | | | | | | should be good, plus it prevents weird things from happening if len > INT_MAX. - Since n is now size_t, compare it against 0 instead of >= 0. - temp is used to store individual bytes, so use char instead (matches fp and tp). - millert noted that the comma operator may not guarantee order of execution, so replace with semicolons. Found by lint, OK millert.
* Convert c to unsigned char, like it says in the manual. Also addray2008-03-151-4/+3

* use pgfree pool like other code does to reserve free list slots.otto2008-02-201-6/+6

* - make arc4random*() functions thread safe. Use a custom spinlock functionkurt2008-01-012-42/+69
| | | | | | | | | | | instead of the generic pthread macros since free(3) uses __arc4_getbyte() when freeing small sized allocations and the generic pthread macros call malloc(3). - eliminate passing pointers to a static variable with global scope (rs) for additional code clarity and reduction. - shlib minor bumps for libc and libpthread due to new functions. From andreas@ with some bits from me. okay tedu@ marc@ w/some spot checking from millert@

* _FD_LOCK/UNLOCK() is libpthread specific and not needed for librthread, sokurt2007-06-051-21/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | isolate its usage to libpthread only and replace with generic non-static mutex support in the one place it is needed: - remove _FD_LOCK/UNLOCK from lseek and ftruncate in libc and make the functions weak so that libpthread can override with its own new versions that do the locking. - remove _thread_fd_lock/unlock() weak functions from libc and adjust libpthread for the change. - add generic _thread_mutex_lock/unlock/destroy() weak functions in libc to support non-static mutexes in libc and add libpthread and librthread implementations for them. libc can utilize non-static mutexes via the new _MUTEX_LOCK/UNLOCK/DESTROY() macros. Actually these new macros can support both static and non-static mutexes but currently only using them for non-static. - make opendir/closedir/readdir/readdir_r/seekdir/telldir() thread-safe for both thread libraries by using a non-static mutex in the struct _dirdesc (typedef DIR), utilizing it in the *dir functions and remove remaining and incorrect _FD_LOCK/UNLOCK() use in libc. - add comments to both thread libraries to indicate libc depends on the current implementation of static mutex initialization. suggested by marc@ - major bump libc and libpthread due to function removal, structure change and weak symbol conversions. okay marc@, tedu@
