Lovely... That would get an empty path and non-directory for a starting point, but it should end up with LAST_ROOT in nd->last_type. Which should not be able to reach the readers of those fields... Which kernel had that been on?Yecchhh... I see what's going on; I suspect that this ought to be enough. Folks, could somebody test it on the original reproducer setup?
Sure. I can do that. Thanks, Anant _______________________________________________ Linux-kernel-mentees mailing list Linux-kernel-mentees@lists.linuxfoundation.org https://lists.linuxfoundation.org/mailman/listinfo/linux-kernel-mentees
