From 2d472b48610f6a298d28035b683ab13e9afac4cb Mon Sep 17 00:00:00 2001 From: Florian Weimer Date: Mon, 24 Jul 2023 15:12:26 +0200 Subject: nscd: Use errval, not errno to guide cache update (bug 30662) The errno variable is potentially clobbered by the preceding send call. It is not related to the to-be-cached information. The parallel code in hstcache.c and servicescache.c already uses errval.
