From 8b222fa38700422b4da6731806835f0bbf40920d Mon Sep 17 00:00:00 2001 From: Florian Weimer Date: Mon, 20 Jan 2020 18:37:13 +0100 Subject: getaddrinfo: Fix resource leak after strdup failure in gethosts [BZ #25425] Filip Ochnik spotted that one of the error jumps in gethosts fails to call __resolv_context_put to release the resolver context. Fixes commit 352f4ff9a268b81ef5d4b2413f582565806e4790 ("resolv: Introduce struct resolv_context [BZ #21668]") and commit 964263bb8d650f1681665c55704fb01a8e725621 ("getaddrinfo: Release resolver context on error in gethosts [BZ #21885]").
