Bug#512733: linux-2.6: enabling STRICT_DEVMEM
Package: linux-2.6
Severity: wishlist
Hi,
in unofficial linux kernels from
http://kernel-archive.buildserver.net/debian-kernel (but that will
become official as soon as they are uploaded into sid), the
STRICT_DEVMEM option is not set:
$ grep STRICT_DEVMEM /boot/config-2.6.*
/boot/config-2.6.27-1-686:# CONFIG_STRICT_DEVMEM is not set
/boot/config-2.6.28-1-686:# CONFIG_STRICT_DEVMEM is not set
According to http://lwn.net/Articles/308426/ it might be a good idea to
enable this option in order to prevent user space programs to
accidentally corrupt memory allocated by drivers, with possible negative
consequences such as file system corruption or even hardware damage
(e1000e for example).
