Troubleshooting GRSEC/PaX stability issues on on 3.12.6
Posted: Tue Jan 07, 2014 8:44 pmHello,
This is a grsec patched Arch kernel of 3.12.6-grsec x86_64. This is the first time using grsec for me and it seems to work rather well!
But I have run into a few problems I was wondering if someone might be able to point me in the right direction.
1) My x-session automatically logs off after a few minutes, this only happens on the grsec kernel. Is there anyway to disable this? Or at least set it to a longer period of time since it kills updates and currently running programs every time I step away from the PC...
2) Two gnome-games cause some type of grsec conflict which results in all Ctrl keys to be non-functioning and su and sudo to be inaccessible. They are:
/usr/bin/gnome-nibbles
grsec: bruteforce prevention initiated due to crash of /usr/bin/gnome-nibbles against uid 1000, banning suid/sgid execs for 15 minutes. Please investigate the crash report for /usr/bin/gnome-nibbles[gnome-nibbles:3569]
/usr/bin/lightsoff
grsec: denied resource overstep by requesting 64 for RLIMIT_CORE against limit 0 for /usr/bin/lightsoff[lightsoff:4814] uid/euid:1000/1000 gid/egid:100/100, parent /usr/bin/bash[bash:4802] uid/euid:1000/1000 gid/egid:100/100
