Details

Description: The latest version of the linux-grsec kernel doesn't include support for the Flash Friendly Filesystem (F2FS), unlike the preceding versions. I have not found any information on a problem between grsecurity and f2fs, so I would assume the kernel module is simply missing.


Additional info:
Package Version: linux-grsec 3.18.5.201501310706-1


Steps to reproduce:
Using "cat /proc/filesystems" or trying to mount a f2fs-formatted device.
This task depends upon

According to the filelist at https://www.archlinux.org/packages/community/x86_64/linux-grsec/, the module is there: usr/lib/modules/3.18.5.201501310706-1-grsec/kernel/fs/f2fs/f2fs.ko.gz

What happens when you try to modprobe it? Maybe try depmod?

You are correct, the module is there, and in fact now it does correctly load when inserting a f2fs-formatted usbkey (after I reinstalled the linux-grsec packages and rebooted once more). I also had the problem on a root filesystem (Arch installation on another usbkey) which could not be mounted, resulting in the obvious panic. Upon further inspection, that must have been a problem with mkinitcpio, because recreating the initramfs fixed the problem. My bad for seeing a similar bug in two places and assuming the cause was the grsec kernel. Sorry for the inconvenience.
