* First pass at removing clauses 3 and 4 from NetBSD licenses.ray2008-06-261-9/+2
| | | | | | | | | 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@

* - 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@
* 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@

| | | | OK millert@
* strtod may return HUGE_VAL on overflow, which is defined in math.h.tobias2007-11-111-2/+3
| | | | | | Therefore added math.h to SYNPOSIS. OK millert@

* from ginsbach@netbsd, -r1.18:jmc2007-07-031-2/+7
| | | | | | | | Document that getopt_long(3) can and will accept unique abbreviated long option names. This feature has been present since getopt_long(3) was first released in NetBSD 1.5. This is also standard GNU getopt_long(3) behavior. ok millert

* 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@

| | | | | | | | | 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@
