The unending stream of syzbot bug reports and overwrought filing of CVEs for corner case handling (i.e. things that distract from actual user complaints) in XFS has generated all sorts of of overheated rhetoric about how every bug is a Serious Security Issue(tm) because anyone can craft a malicious filesystem on a USB stick, insert the stick into a victim machine, and mount will trigger a bug in the kernel driver that leads to some compromise or DoS or something. I thought that nobody would be foolish enough to automount an XFS filesystem. What a fool I was! It turns out that udisks can be told that it's okay to automount things, and then GNOME will do exactly that. Including mounting mangled XFS filesystems! Same with bcachefs! <delete angry rant about poor decisionmaking and armchair fs developers blasting us on X while not actually doing any of the work> Turn off /this/ idiocy by adding a udev rule to tell udisks not to automount bcachefs filesystems. This will not stop a logged in user from unwittingly inserting a malicious storage device and pressing [mount] and getting breached. This is not a substitute for a thorough audit. This is not a substitute for lklfuse. This does not solve the general problem of in-kernel fs drivers being a huge attack surface. I just want to give Kent a break from some of the oceans of bu******. Signed-off-by: Darrick J. Wong <djwong@kernel.org> Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
bcachefs-tools
Userspace tools and docs for bcachefs
Bcachefs is an advanced new filesystem for Linux, with an emphasis on reliability and robustness and the complete set of features one would expect from a modern filesystem.
This repo primarily consists of the following:
- bcachefs tool, the reason this repo exists.
- {mkfs,mount,fsck}.bcachefs utils, which is just wrappers calling the corresponding subcommands in the main tool
- docs in the form of man-pages and a user manual
Please refer to the main site for getting started An in-depth user manual is (also) found on the official website
Build and install
Refer to INSTALL.md
