• Product: Gentoo Linux
• Status: RESOLVED OBSOLETE

[Description Nikoli 2013-07-16 17:43:20 UTC]

When running weston-launch my dmesg has RWX mmap errors:
[67790.947344] grsec: denied RWX mmap of <anonymous mapping> by /usr/libexec/weston-screensaver[weston-screensa:24286] uid/euid:1101/1101 gid/egid:1101/1101, parent /usr/libexec/weston-desktop-shell[weston-desktop-:24279] uid/euid:1101/1101 gid/egid:1101/1101

Asked in #wayland:
[21:31:33] <Nikoli> there are a lot RWX mmap messages in dmesg when using weston http://bpaste.net/raw/114782/
[21:32:02] <Nikoli> will they be fixed or it is not possible by design?
[21:32:57] <krh> Nikoli: we don't allocate anything X
[21:33:01] <krh> s/allocate/map
[21:33:42] <Nikoli> so why i have such messages?
[21:33:44] <krh> Nikoli: git grep PROT_EXEC -> nothing
[21:34:14] <Nikoli> when using 3d x11 apps with radeon foss driver i do not have such errors in dmesg
[21:34:18] <krh> good question
[21:34:32] <Nikoli> so it is mesa?
[21:36:42] <krh> Nikoli: could be mesa, yes

I've removed wayland/weston < 1.6.1.
