+From cb867d2fd64adc851f82be3c6eb6e38ec008930b Mon Sep 17 00:00:00 2001
+From: Dominik Honnef <dominik@honnef.co>
+Date: Sun, 21 Jun 2015 20:07:29 +0200
+Subject: [PATCH] os/user: don't depend on _SC_GETPW_R_SIZE_MAX on Linux
+
+Even Linux systems may not have _SC_GETPW_R_SIZE_MAX if using a
+different libc than glibc (e.g. musl). Instead of having special-cases
+for the BSDs, handle -1 correctly by always using a default buffer size.
+
+Fixes #11319.
