+X-Git-Url: https://sourceware.org/git/?p=glibc.git;a=commitdiff_plain;h=a1a20f029299dc27170912bb9233070c8403444d
+
+resolv: Fix file handle leak in __resolv_conf_load [BZ #25429]
+
+res_vinit_1 did not close the stream on errors, only on success.
+This change moves closing the stream to __resolv_conf_load, for both
+the success and error cases.
+
+Fixes commit 89f187a40fc0ad4e22838526bfe34d73f758b776 ("resolv: Use
+getline for configuration file reading in res_vinit_1") and commit
+3f853f22c87f0b671c0366eb290919719fa56c0e ("resolv: Lift domain search
+list limits [BZ #19569] [BZ #21475]"), where memory allocation was
+introduced into res_vinit_1.
