* Tighten the ranges in wcrtomb(3).bentley2015-10-131-2/+2
| | | | | | | | | | | | By definition, the range of valid Unicode code points is the union of U+0000..U+D7FF and U+E000..U+10FFFF (see Unicode 8.0.0, chapter 3.9). In UTF-16, the encoded values that would represent U+D800..U+DFFF are used for surrogate pairs. UTF-8 has no concept of surrogate pairs; attempting to treat them as regular code points violates the standard and makes no sense besides. ok stsp@

* When isatty() was switched to F_ISATTY, the inline copy in ttyname()naddy2015-10-121-4/+2

* Make wcrtomb() more readable by weeding out range errors up front,schwarze2015-10-121-14/+11
| | | | | | | doing ASCII handling once rather than twice, and using <= rather than ((&~)==) obfuscation (which already caused a bug in the past). No functional change. Joint work with and OK stsp@ semarie@ bentley@

* Do not insert whitespace into syntax displays, it's just confusing,schwarze2015-10-111-49/+23
| | | | | | | | except at the one place where it is indeed helpful. Add some missing .Cm macros. Remove some useless escaping, one needless .Xo, and an empty .No. Triggered by a much smaller patch from guenther@. OK jmc@ guenther@
* Fix empty .No macros, use .Pf to prefix delimiters to macros.schwarze2015-10-111-4/+4
| | | | | Based on a patch from guenther@, tweaked by me. OK jmc@ guenther@

* tame -> pledge conversion, in libc. I should crank libc, but am cheatingderaadt2015-10-094-19/+38
| | | | | | hoping things go well. The old symbol is faked via a stupid stub function, until next major crank when it can be removed. I am expecting guenther to scream at me.

* getaddrinfo_async() shouldn't unconditionally intialize the resolverderaadt2015-10-073-4/+14
| | | | | | via _asr_use_resolver(). If the hint specifies for AI_NUMERICHOST, create a transient lookup context which won't try to open /etc/reslov.conf ok eric guenther
* getaddrinfo() should not res_init() unconditionally, but allow lowerderaadt2015-10-071-2/+3
| | | | | | layers to decide. The request could be AI_NUMERICHOST. [And the process could be tame()-constrained to not open /etc/resolv.conf] ok eric guenther

* recv() and send() aren't overriden by libpthread (vs recvfrom() and sendto()!)guenther2015-10-043-3/+7

* Initially eric developers asr as a side-load style library for async DNS.deraadt2015-10-032-65/+15
| | | | | | | When it was integrated as the main resolver, a bunch of strange initialization code remained. Start whittling away at this, piece by piece, to make it more clear. ok eric

* implement new "prot_exec" tame(2) request:semarie2015-09-301-3/+15
| | | | | | | | | | | - by default, a tamed-program don't have the possibility to use PROT_EXEC for mmap(2) or mprotect(2) - for that, use the request "prot_exec" (that could be dropped later) initial idea from deraadt@ and kettenis@ "make complete sense" beck@ ok deraadt@

* xdr_ypresp_all_seq() does not need to be exported by libc, we can make itderaadt2015-09-282-5/+4
| | | | | | | | local static. (Does not need to be exported by librpcsvc either, since it is pre-rpcgen and simply %-commented). A few callers use this via yp_all() -- that interface remains untouched. ports trawl by sthen guenther watched me gnash my teeth in croatia

| | | | | | | | | | RFC 3629 (limiting the range of UTF-8 to 0x10FFFF). it is the counterpart of a previous commit correcting mbrtowc(3). problem spotted by stsp ok bentley@ stsp@
