* First pass at removing clauses 3 and 4 from NetBSD licenses.ray2008-06-262-18/+4
| | | | | | | | | Not sure what's more surprising: how long it took for NetBSD to catch up to the rest of the BSDs (including UCB), or the amount of code that NetBSD has claimed for itself without attributing to the actual authors. OK deraadt@

| | | | | | | 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

* - do not call pthread_atfork(3) handlers when a multithreaded programkurt2008-04-041-2/+7
| | | | | | 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@
* Zero state buffers on return. OK deraadt@millert2008-04-021-1/+5

* bcmp(3) tries to return length, which is a size_t, as an int.ray2008-03-191-4/+4
| | | | | | | | Instead, just return 1 if there is a difference. Found by lint. OK millert.
* - add NAME entries for arc4random_buf and arc4random_uniformjmc2008-03-161-2/+4

* 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
| | | | | | cast to make it explicit. Found by lint, OK millert.
* use pgfree pool like other code does to reserve free list slots.otto2008-02-201-6/+6
| | | | | prevents a few "cannot free mem because i need mem to free mem" scenarios (one found by weingart@). ok weingart@ millert@ miod@
* - 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@
