[PATCH] bits/byteswap-common.h: import recent headers from glibc
by Anthony G. Basile 25 Mar '16

25 Mar '16

From: "Anthony G. Basile" <blueness(a)gentoo.org> On systems where uClibc doesn't provide an arch specific byteswap.h, we fall back on bits/byteswap-common.h. However, there is a bug in this header in the __bswap_constant_64(x) macro. If, for example, a double is passed, we get "invalid operands to binary &" in which we mismatch a 'double' and 'long long unsigned int'. The newer glibc headers fix this and so we import them. This is needed, for example, for f2fs-tools 1.6.0 on 32-bit big endian PowerPC. Signed-off-by: Anthony G.

[PATCH] DNS: don't count search-path miss as a retry
by Tim Hockin 13 Mar '16

13 Mar '16

Currently a miss on a search-path entry is counted as a retry. This means that users with more than (num_nameservers * retries) entries in their search path list fail before trying all search paths. Concretely, a single nameserver with 4 search paths will never try the 4th search because the default retry is 3. The code doesn't currently retry a given nameserver in case of an error, so retries is sort of meaningless (though there are some comments indicating it might come). This change only treats total failure of a nameserver (try next server) as a retry.

[PATCH] getaddrinfo: correct AI_V4MAPPED handling
by Peter Korsgaard 13 Mar '16

13 Mar '16

As recently reported on the Buildroot list: http://lists.busybox.net/pipermail/buildroot/2016-March/155325.html DNS lookups with Node.js currently fails on uClibc-ng. The reason for this is the way AI_V4MAPPED is handled. According to POSIX, AI_V4MAPPED should be ignored unless ai_family is AF_INET6: http://pubs.opengroup.org/onlinepubs/9699919799/functions/freeaddrinfo.html If the AI_V4MAPPED flag is specified along with an ai_family of AF_INET6, then getaddrinfo() shall return IPv4-mapped IPv6 addresses on finding no matching IPv6 addresses (ai_addrlen shall be 16). The AI_V4MAPPED flag shall be ignored unless ai_family equals AF_INET6. uClibc-ng was also handling AI_V4MAPPED for AF_UNSPEC, fix that.

new release 1.0.13 - Chimay Doree
by Waldemar Brodkorb 13 Mar '16

13 Mar '16

Hi, I cut down a new release today. I've made some changes to the infrastructure of the project: - Updated the project server to Debian/jessie - Added a Github mirror: https://github.com/wbx-github/uclibc-ng - All domains are available via SSL with letsencrypt certs - All domains are reachable via IPv6 - Release files and GIT tags are signed with my GnuPG key http://www.waldemar-brodkorb.de/wbx.asc Thanks you very much for all contributions and bug reports. Release includes following changes: Anton Kolesov (2): Advertise obstack only when chosen ARC: Disable obstack Max Filippov (2): xtensa: fix stack unwinding over __default_sa_restorer arm: fix __JMP_BUF_SP definition Peter Korsgaard (1): getaddrinfo: correct AI_V4MAPPED handling Thomas Claveirole (1): include/netdb.h: Do not define IDN-related flags. Tim Hockin (2): DNS: don't count search-path miss as a retry DNS: Don't apply search domains to PTR lookups Ubaldo Porcheddu (2): Replaced any occurence of /bin/sh with _PATH_BSHELL to allow easier portability on system with default shell on a different directory, like for instance on android. Replace /etc/resolv.conf with _PATH_RESCONF to allow portability of the code on system where resolv.conf is not in /etc . Waldemar Brodkorb (14): mips: fix build if threads are disabled frv: resurrect port somehow, totally untested libm: add ULPS for cris architecture refresh xtensa ulps file increase timeouts to successfully run on slower hardware/emulation, f.e. xtensa libm: remove dead code mark a.out support as not available test: update ulps file for ARM test: update ulps for SPARC mips64: with n64 ABI mapping failed arm: allow to build with DODEBUG=y ia64: disable atomic tests ia64: sync with glibc headers bump version for release
