From 73f6b1f68ddfc616c46277b1d5a623001ca3b0e5 Mon Sep 17 00:00:00 2001 From: Stefan Agner Date: Fri, 15 Nov 2019 16:09:44 +0000 Subject: base-files: set ptmxmode to 666 Make sure that the (newer) /dev/pts/ptmx is accessible by users. This is useful e.g. when running containers which symlink /dev/ptmx to /dev/pts/ptmx on start. The default mode (000) does not allow to create ptys inside the container. Using 666 when symlinking /dev/ptmx is also recommended by the kernel documentation when /dev/ptmx is symlinked: https://www.kernel.org/doc/Documentation/filesystems/devpts.txt Also buildroot uses ptmxmode=0666. The patch introducing the change explains related use cases why this is necessary a bit more in depth: https://github.com/buildroot/buildroot/commit/8196b299ba12bd6741bf7f4462cad180dab77fb0#diff-2d4604b9e565eb19fa52ce31f282f06c (From OE-Core rev: c999bc5ddd9beb5274f77b885e2ac71205e42266) Signed-off-by: Stefan Agner Signed-off-by: Richard Purdie --- meta/recipes-core/base-files/base-files/fstab | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'meta/recipes-core/base-files') diff --git a/meta/recipes-core/base-files/base-files/fstab b/meta/recipes-core/base-files/base-files/fstab index d79a01602f..70e400f567 100644 --- a/meta/recipes-core/base-files/base-files/fstab +++ b/meta/recipes-core/base-files/base-files/fstab @@ -2,7 +2,7 @@ /dev/root / auto defaults 1 1 proc /proc proc defaults 0 0 -devpts /dev/pts devpts mode=0620,gid=5 0 0 +devpts /dev/pts devpts mode=0620,ptmxmode=0666,gid=5 0 0 tmpfs /run tmpfs mode=0755,nodev,nosuid,strictatime 0 0 tmpfs /var/volatile tmpfs defaults 0 0 -- cgit v1.2.3-54-g00ecf
