:Hi!
:
:There is very frequently asked (at least, in Russian newsgroups) question:
:is it possible to make Midnight Commander enter to archives on msdosfs
:and stop his attempts to execute files there? The only way is to
:use '-m 644', but then you can enter directories as root only.
:Finally I got tired of these questions and patched kernel,
:mount_msdosfs and its man page to accept new option '-M mask'.
:This mask is used for directories only, if supplied.
:If -M is used and -m is not then supplied mask is used for all objects.
:I do not run CURRENT so this patch is for 4.5RC1
:That is my first 6K kernel patch so please review.
:It works at least for me :-)
Why not simply mount the filesystem with the 'noexec' flag?
The patch looks fine, but I don't like the idea of such a targeted
hack being added to the mount code and we definitely do not want to
go changing msdosfs's mount structure just before the release either.
-Matt
