exfat currently unconditionally strips trailing periods '.' when performing path lookup, but allows them in the filenames during file creation. This is done intentionally, loosely following Windows behaviour and specifications which state: #exFAT The concatenated file name has the same set of illegal characters as other FAT-based file systems (see Table 31). #FAT ... Leading and trailing spaces in a long name are ignored. Leading and embedded periods are allowed in a name and are stored in the long name. Trailing periods are ignored. Note: Leading and trailing space ' ' characters are currently retained by Linux kernel exfat, in conflict with the above specification. On Windows 10, trailing and leading space ' ' characters are stripped from the filenames . Some implementations, such as fuse-exfat, don't perform path trailer removal. When mounting images which contain trailing-dot paths, these paths are unreachable, e.g.: + mount.exfat-fuse /dev/zram0 /mnt/test/ FUSE exfat 1.3.0 + cd /mnt/test/ + touch fuse_created_dots... ' fuse_created_spaces ' + ls -l total 0 -rwxrwxrwx 1 root 0 0 Aug 18 09:45 ' fuse_created_spaces ' -rwxrwxrwx 1 root 0 0 Aug 18 09:45 fuse_created_dots... + cd / + umount /mnt/test/ + mount -t exfat /dev/zram0 /mnt/test + cd /mnt/test + ls -l ls: cannot access 'fuse_created_dots...': No such file or directory total 0 -rwxr-xr-x 1 root 0 0 Aug 18 09:45 ' fuse_created_spaces ' -????????? ? ? ? ? ? fuse_created_dots... + touch kexfat_created_dots... ' kexfat_created_spaces ' + ls -l ls: cannot access 'fuse_created_dots...': No such file or directory total 0 -rwxr-xr-x 1 root 0 0 Aug 18 09:45 ' fuse_created_spaces ' -rwxr-xr-x 1 root 0 0 Aug 18 09:45 ' kexfat_created_spaces ' -????????? ? ? ? ? ? fuse_created_dots... -rwxr-xr-x 1 root 0 0 Aug 18 09:45 kexfat_created_dots + cd / + umount /mnt/test/ This commit adds "keep_last_dots" mount option that controls whether or not trailing periods '.' are stripped from path components during file lookup or file creation. This mount option can be used to access paths with trailing periods and disallow creating files with names with trailing periods. E.g. continuing from the previous example: + mount -t exfat -o keep_last_dots /dev/zram0 /mnt/test + cd /mnt/test + ls -l total 0 -rwxr-xr-x 1 root 0 0 Aug 18 10:32 ' fuse_created_spaces ' -rwxr-xr-x 1 root 0 0 Aug 18 10:32 ' kexfat_created_spaces ' -rwxr-xr-x 1 root 0 0 Aug 18 10:32 fuse_created_dots... -rwxr-xr-x 1 root 0 0 Aug 18 10:32 kexfat_created_dots + echo > kexfat_created_dots_again... sh: kexfat_created_dots_again...: Invalid argument Link: https://bugzilla.suse.com/show_bug.cgi?id=1188964 Link: https://lore.kernel.org/linux-fsdevel/003b01d755e4$31fb0d80$95f12880$ @samsung.com/ Link: https://docs.microsoft.com/en-us/windows/win32/fileio/exfat-specification Suggested-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Vasant Karasulli <vkarasulli@suse.de> Co-developed-by: David Disseldorp <ddiss@suse.de> Signed-off-by: David Disseldorp <ddiss@suse.de> Signed-off-by: Namjae Jeon <linkinjeon@kernel.org> |

exFAT filesystem
This is the exfat filesystem for support from the linux 4.1 kernel to the latest kernel.
Installing as a stand-alone module
Install prerequisite package for Fedora, RHEL:
yum install kernel-devel-$(uname -r)
Build step:
make
sudo make install
To load the driver manually, run this as root:
modprobe exfat
Installing as a part of the kernel
- Let's take [linux] as the path to your kernel source dir.
cd [linux]
cp -ar exfat [linux]/fs/
- edit [linux]/fs/Kconfig
source "fs/fat/Kconfig"
+source "fs/exfat/Kconfig"
source "fs/ntfs/Kconfig"
- edit [linux]/fs/Makefile
obj-$(CONFIG_FAT_FS) += fat/
+obj-$(CONFIG_EXFAT_FS) += exfat/
obj-$(CONFIG_BFS_FS) += bfs/
- make menuconfig and set exfat
