* - replace dtoa w/ David's gdtoa, version 2008-03-15martynas2008-09-073-2500/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - provide proper dtoa locks - use the real strtof implementation - add strtold, __hdtoa, __hldtoa - add %a/%A support - don't lose precision in printf, don't round to double anymore - implement extended-precision versions of libc functions: fpclassify, isnan, isinf, signbit, isnormal, isfinite, now that the ieee.h is fixed - separate vax versions of strtof, and __hdtoa - add complex math support. added functions: cacos, casin, catan, ccos, csin, ctan, cacosh, casinh, catanh, ccosh, csinh, ctanh, cexp, clog, cabs, cpow, csqrt, carg, cimag, conj, cproj, creal, cacosf, casinf, catanf, ccosf, csinf, ctanf, cacoshf, casinhf, catanhf, ccoshf, csinhf, ctanhf, cexpf, clogf, cabsf, cpowf, csqrtf, cargf, cimagf, conjf, cprojf, crealf - add fdim, fmax, fmin - add log2. (adapted implementation e_log.c. could be more acruate & faster, but it's good enough for now) - remove wrappers & cruft in libm, supposed to work-around mistakes in SVID, etc.; use ieee versions. fixes issues in python 2.6 for djm@ - make _digittoint static - proper definitions for i386, and amd64 in ieee.h - sh, powerpc don't really have extended-precision - add missing definitions for mips64 (quad), m{6,8}k (96-bit) float.h for LDBL_* - merge lead to frac for m{6,8}k, for gdtoa to work properly - add FRAC*BITS & EXT_TO_ARRAY32 definitions in ieee.h, for hdtoa&ldtoa to use - add EXT_IMPLICIT_NBIT definition, which indicates implicit normalization bit - add regression tests for libc: fpclassify and printf - arith.h & gd_qnan.h definitions - update ieee.h: hppa doesn't have quad-precision, hppa64 does - add missing prototypes to gdtoaimp - on 64-bit platforms make sure gdtoa doesn't use a long when it really wants an int - etc., what i may have forgotten... - bump libm major, due to removed&changed symbols - no libc bump, since this is riding on djm's libc major crank from a day ago discussed with / requested by / testing theo, sthen@, djm@, jsg@, merdely@, jsing@, tedu@, brad@, jakemsr@, and others. looks good to millert@ parts of the diff ok kettenis@ this commit does not include: - man page changes

* Add resolv.conf(5) option to force lookups by TCP: "options tcp"djm2008-08-151-18/+20
| | | | | | | | | | | | | | Also Extend "nameserver" declaration syntax to support port numbers. To avoid ambiguity these are only parsed when the address is enclosed in square brackets, e.g. "nameserver [127.0.0.1]:5353" Together these changes make forwarding DNS over a SSH tunnel very easy, but unfortunately some programs in ports/ implement their own resolvers (e.g. firefox). These will need to be modified to support these options separately. fixes jsing@ reyk@ ok deraadt@ millert@ krw@ + "I like it" from lots

* 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@

* 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@
