./net/adns, Asynchronous-capable DNS client library and utilities

[ CVSweb ] [ Homepage ] [ RSS ] [ Required by ] [ Add to tracker ]

Branch: CURRENT, Version: 1.6.0, Package name: adns-1.6.0, Maintainer: pkgsrc-users

adns is a DNS resolver library and a collection of utilities that use the
library. The adns library has the following features:
* It is reasonably easy to use for simple programs which just want to
translate names to addresses, look up MX records, etc.
* It can be used in an asynchronous, non-blocking, manner. Many
queries can be handled simultaneously.
* Responses are decoded automatically into a natural representation
for a C program - there is no need to deal with DNS packet formats.
* Sanity checking (eg, name syntax checking, reverse/forward
correspondence, CNAME pointing to CNAME) is performed automatically.
* Time-to-live, CNAME and other similar information is returned in an
easy-to-use form, without getting in the way.
* There is no global state in the library; resolver state is an
opaque data structure which the client creates explicitly. A
program can have several instances of the resolver.
* Errors are reported to the application in a way that distinguishes
the various causes of failure properly.
* Understands conventional resolv.conf, but this can overridden by
environment variables.
* Flexibility. For example, the application can tell adns to: ignore
environment variables (for setuid programs), disable hostname
syntax sanity checks to return arbitrary data, override or ignore
resolv.conf in favour of supplied configuration, etc.
...and more!

Log message:
adns: Update to 1.6.0
adns (1.6.0) UPSTREAM; urgency=medium
  Bugfixes:
  * adnshost: Support --reverse in -f mode input stream
  * timeout robustness against clock skew: track query start time and
    duration.  Clock instability may now only cause spurious timeouts
    rather than indefinite hangs or even assertion failures.
  New features:
  * adnshost: Offer ability to set adns checkc flags
  * adnslogres: Honour --checkc-freq (if it comes first)
  * adnsresfilter: Honour --checkc-freq and --checkc-entex
  * time handling: Support use of CLOCK_MONOTONIC via an init flag.
  * adns_str* etc.: Improve robustness; more allowable inputs values.
  Build system improvements:
  * clean targets: Delete $(TARGETS) too!
  * Remove all m4 output files from the distributed source tree.
  * Support DESTDIR=/some/absolute/path on `make install'.
  * Provide autogen.sh.
  * Rerun autoheader and autoconf (2.69).
  Internal changes:
  * adnshost: adh-opts.c: Whitespace adjustments to option table
  Tests:
  * New tests for fixes in 1.5.3.
  * Fixes to test harness to avoid false positives during fuzzing.
  * Other changes to support use with AFL.
  * Many supporting improvements and refactorings.
  * Fix skipped tests ($$ reference in Makefile)

adns (1.5.2) UPSTREAM; urgency=medium
  * Important security fixes:
     CVE-2017-9103 CVE-2017-9104 CVE-2017-9105 CVE-2017-9109:
	Vulnerable applications: all adns callers.
        Exploitable by: the local recursive resolver.
	Likely worst case: Remote code execution.
     CVE-2017-9106:
	Vulnerable applications: those that make SOA queries.
        Exploitable by: upstream DNS data sources.
	Likely worst case: DoS (crash of the adns-using application)
     CVE-2017-9107:
	Vulnerable applications: those that use adns_qf_quoteok_query.
        Exploitable by: sources of query domain names.
	Likely worst case: DoS (crash of the adns-using application)
     CVE-2017-9108:
	Vulnerable applications: adnshost.
        Exploitable by: code responsible for framing the input.
        Likely worst case: DoS (adnshost crashes at EOF).
    All found by AFL 2.35b.  Thanks to the University of Cambridge
    Department of Applied Mathematics for computing facilities.
  Bugfixes:
  * Do not include spurious external symbol `data' (fixes GCC10 build).
  * If server sends TC flag over TCP, bail rather than retrying.
  * Do not crash on certain strange resolv.conf contents.
  * Fix various crashes if a global system failure occurs, or
    adns_finish is called with outstanding queries.
  * Correct a parsing error message very slightly.
  * DNS packet parsing: Slight fix when packet is truncated.
  * Fix ABI compatibility in string conversion of certain RR types.
  * internal.h: Use `unsigned' for nextid; fixes theoretical C UB.
  Portability fix:
  * common.make.in: add -Wno-unused-value.  Fixes build with GCC9.
  Internal changes:
  * Additional comments describing some internal code restrions.
  * Robustness assert() against malfunctioning write() system call.

Log message:
Updated net/adns to 1.5.1
-------------------------
adns (1.5.1) UPSTREAM; urgency=medium
  * Portability fix for systems where socklen_t is bigger than int.
  * Fix for malicious optimisation of memcpy in test suite, which
    causes failure with gcc-4.1.9 -O3.  See Debian bug #772718.
  * Fix TCP async connect handling.  The bug is hidden on Linux and on most
    systems where the nameserver is on localhost.  If it is not hidden,
    adns's TCP support is broken unless adns_if_noautosys is used.
  * Fix addr queries (including subqueries, ie including deferencing MX
    lookups etc.) not to crash when one of the address queries returns
    tempfail.  Also, do not return a spurious pointer to the application
    when one of the address queries returns a permanent error (although,
    the application almost certainly won't use this pointer because the
    associated count is zero).
  * adnsresfilter: Fix addrtextbuf buffer size.  This is not actually a
    problem in real compiled code but should be corrected.
  * Properly include harness.h in adnstest.c in regress/.  Suppresses
    a couple of compiler warnings (implicit declaration of Texit, etc.)
