From 9d797ee2dce1e3e243bcc18dad7728df72fd11a4 Mon Sep 17 00:00:00 2001 From: Kuniyuki Iwashima Date: Mon, 26 Jun 2023 13:58:37 -0700 Subject: Revert "af_unix: Call scm_recv() only after scm_set_cred()." This reverts commit 3f5f118bb657f94641ea383c7c1b8c09a5d46ea2. Konrad reported that desktop environment below cannot be reached after commit 3f5f118bb657 ("af_unix: Call scm_recv() only after scm_set_cred().") - postmarketOS (Alpine Linux w/ musl 1.2.4) - busybox 1.36.1 - GNOME 44.1 - networkmanager 1.42.6 - openrc 0.47 Regarding to the warning of SO_PASSPIDFD, I'll post another patch to suppress it by skipping SCM_PIDFD if scm->pid == NULL in scm_pidfd_recv().
