2018-04-28Remove references to the obsolete getnetent(3) and networks(5).Ingo Schwarze
2018-04-28Stop talking about /etc/networks, which is no longer used,Ingo Schwarze
and reference gethostby*(3) and /etc/hosts instead. Say that setnetent(3), getnetent(3), and endnetent(3) now do nothing. With feedback from guenther and significant help from deraadt@.
2018-04-28Say that sethostent(3), gethostent(3), and endhostent(3) do nothing.Ingo Schwarze
While here, stop implying plans to support additional address families in the future, and do not call gethostbyname2(3) "advanced". OK deraadt@ guenther@
2018-04-28To allow us to get rid of /etc/networks, make setnetent(3),Ingo Schwarze
getnetent(3), and endnetent(3) do nothing, just like sethostent(3), gethostent(3), and endhostent(3) years ago. OK deraadt@ guenther@

crash when given a large hex number as part of the dotted quad. OK deraadt@ jsg@
2017-02-27Add support for RES_USE_DNSSECJeremie Courreges-Anglas
RES_USE_DNSSEC is implemented by setting the DNSSEC DO bit in outgoing queries. The resolver is then supposed to set the AD bit in the reply if it managed to validate the answer through DNSSEC. Useful when the application doesn't implement validation internally. This scheme assumes that the validating resolver is trusted and that the communication channel between the validating resolver and and the client is secure. ok eric@ gilles@
2017-02-18Add EDNS0 support.Jeremie Courreges-Anglas
EDNS allows for various DNS extensions, among which UDP DNS packets size bigger than 512 bytes. The default is still to not advertize anything. ok eric@

2016-12-06CVE-2016-6559: fix potential buffer overflow(s) in link_ntoa(3).Todd C. Miller
A specially crafted struct sockaddr_dl argument can trigger a stack overflow of a static buffer in libc. An attacker may be able to use this to write to arbitrary locations in the data segment. From FreeBSD (glebius); OK deraadt@ mestre@
2016-09-21Delete casts to off_t and size_t that are implied by assignmentsPhilip Guenther
or prototypes. Ditto for some of the char* and void* casts too. verified no change to instructions on ILP32 (i386) and LP64 (amd64) ok natano@ abluhm@ deraadt@ millert@
2016-08-05Obvious minor fixes:Ingo Schwarze
* Add missing .Dv, .Ev, and .Fa macros. * Delete deprecated .Tn macros. * Mark up global variable names with .Va, not with .Fa or .Li. * Mark up config file commands with .Ic, not with .Fa. * Fix HISTORY, trivial to verify from the CSRG archive CD.

2016-03-30for some time now mandoc has not required MLINKS to functionJason McIntyre
correctly - logically complete that now by removing MLINKS from base; authors need only to ensure there is an entry in NAME for any function/ util being added.

2015-12-16Remove support for HOSTALIASES from the resolver. This "open and parseTheo de Raadt
any file indicated by an environment variable" feature inside the resolver is incompatible with what pledge "dns" is trying to be. It is a misguided "feature" added way back in history which almost noone uses, but everyone has to assume the risk from. ok eric florian kettenis

2015-11-24Use reentrant versions of getpw{nam,uid} and getgr{nam,gid} withinTodd C. Miller
libc to avoid reusing the static buffers returned by the non-reentrant versions. Since this is inside libc we can use constants for the buffer sizes instead of having to call sysconf(). OK guenther@ deraadt@
