and libbind. The handoff of the maintainership from ISC to NetBSD happened in July 2013. |
|
|
|
Patches of NetBSD (June 2013 head) against libbind-6.0 are available at: |
|
<http://ftp.netbsd.org/pub/NetBSD/misc/reed/libbsdnet/> |
|
|
|
libbind provides portability headers: port_before.h and port_after.h |
|
|
|
### port |
|
port directory provides portability headers for many operating sytems |
|
make directory provides common Makefile rules and mkdep |
|
|
|
### bsd |
|
bsd directory contains compatibility code, such as: |
|
daemon(), __ftruncate(), isc__gettimeofday(), gettimeofday(), |
|
mkstemp(), mktemp(), gettemp(), putenv(), __readv(), setenv(), |
|
unsetenv(), findenv(), __setitimer(), strcasecmp(), strncasecmp(), |
|
strdup(), isc_strerror(), strpbrk(), strsep(), strtoul(), __utimes(), |
|
__writev(), __writev() |
|
|
|
### dst |
|
dst directory contains the Digital Signature Toolkit |
|
code for the DST API and crypto API. |
|
Parts of NetBSD's copy of libbind in src/lib/libc use |
|
this, The dst code is not included in NetBSD's src. Probably the code in src/lib/libc using it actually is |
|
not used. |
|
|
|
### inet |
|
|
|
/usr/src/common/lib/libc/inet/inet_addr.c |
|
|
|
NetBSD adds _inet_aton.c and _inet_pton.c |
|
|
|
libbind has (and NetBSD does not have) inet_data in inet. |
|
|
|
### irs |
|
irs is the Information Retrieval System; it provides |
|
getaddrinfo, gethostbyname, and related. |
|
NetBSD doesn't include irs directory as is. But is comparable |
|
to some of what we have in /usr/src/lib/libc/net/ |
|
|
|
NetBSD doesn't have |
|
dns.c top-level accessor function for the dns, |
|
dns_gr.c for hesiod, |
|
gai_strerror.c, |
|
and more. |
|
|
|
### isc |
|
isc directory provides many portability functions |
|
primarily used for ISC software. |
|
|
|
NetBSD only ships with: |
|
src/lib/libc/include/isc/assertions.h |
|
src/lib/libc/include/isc/dst.h |
|
src/lib/libc/include/isc/list.h |
|
src/lib/libc/include/isc/memcluster.h |
|
src/lib/libc/include/isc/eventlib.h |
|
src/lib/libc/include/isc/heap.h |
|
src/lib/libc/isc/assertions.c |
|
src/lib/libc/isc/ev_streams.c |
|
src/lib/libc/isc/ev_timers.c |
|
src/lib/libc/isc/eventlib_p.h |
|
|
|
### nameser provides the name resolver routines to parse DNS responses |
|
|
|
libbind has (and NetBSD does not have) in nameser: |
|
ns_date.c which provides ns_datetosecs(), isleap(), datepart() |
|
ns_newmsg.c for building DNS message packets |
|
ns_rdata.c for unpacking or comparing rdata |
|
ns_sign.c and for ns_verify.c for tsig |
|
|
|
### resolv |
|
|
|
NetBSD adds __dn_comp.c, __res_close.c, __res_send.c, |
|
h_errno.c, res_compat.c, res_state.c. |
|
|
|
libbind has (and NetBSD does not have) in resolv: |
|
(even though NetBSD manual documents them) |
|
res_findzonecut.c |
|
res_mkupdate.c |
|
res_sendsigned.c |
|
res_update.c |
|
|
|
### tests |
|
tests directory contains dig tool from bind8 |
