From 7ae22829afb2b4ca531d1c00437d428f55d59341 Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Sun, 29 May 2011 23:49:49 -0400 Subject: [PATCH] Restore _res correctly getaddrinfo works around the resolver functionality to avoid automatic IPv6 lookups. The restoring didn't allow for the resolver to set additional bits in _res. --- ChangeLog | 5 +++++ NEWS | 14 +++++++------- sysdeps/posix/getaddrinfo.c | 4 ++-- 3 files changed, 14 insertions(+), 9 deletions(-) diff --git a/ChangeLog b/ChangeLog index 6f12343..70dbc40 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,5 +1,10 @@ 2011-05-29 Ulrich Drepper + [BZ #12350] + * sysdeps/posix/getaddrinfo.c (gethosts): Restore only RES_USE_IENT6 + bit from old_res_options. + (gaih_inet): Likewise. + [BZ #11099] * shadow/sgetspent_r.c (LINE_PARSER): Interpret nymeric field values as signed. diff --git a/NEWS b/NEWS index 75f7a0d..05f603f 100644 --- a/NEWS +++ b/NEWS @@ -12,13 +12,13 @@ Version 2.14 386, 6420, 7101, 9730, 9732, 9809, 10138, 10149, 10157, 11099, 11257, 11258, 11487, 11532, 11558, 11578, 11634, 11653, 11668, 11697, 11724, 11781, 11799, 11820, 11837, 11857, 11869, 11892, 11895, 11901, 11945, - 11947, 11952, 11987, 12052, 12083, 12158, 12178, 12200, 12346, 12393, - 12420, 12432, 12445, 12449, 12453, 12454, 12460, 12469, 12489, 12509, - 12510, 12511, 12518, 12527, 12541, 12545, 12551, 12582, 12583, 12587, - 12597, 12601, 12611, 12625, 12626, 12631, 12650, 12653, 12655, 12660, - 12671, 12681, 12685, 12711, 12713, 12714, 12717, 12723, 12724, 12734, - 12738, 12746, 12766, 12775, 12777, 12782, 12788, 12792, 12795, 12811, - 12813, 12814 + 11947, 11952, 11987, 12052, 12083, 12158, 12178, 12200, 12346, 12350, + 12393, 12420, 12432, 12445, 12449, 12453, 12454, 12460, 12469, 12489, + 12509, 12510, 12511, 12518, 12527, 12541, 12545, 12551, 12582, 12583, + 12587, 12597, 12601, 12611, 12625, 12626, 12631, 12650, 12653, 12655, + 12660, 12671, 12681, 12685, 12711, 12713, 12714, 12717, 12723, 12724, + 12734, 12738, 12746, 12766, 12775, 12777, 12782, 12788, 12792, 12795, + 12811, 12813, 12814 * The RPC implementation in libc is obsoleted.
