[PATCH v2 0/2] exfat: allow access to paths with trailing dots

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This patchset is the version 2 of the patch that introduces
a new exfat mount option 'keep_last_dots' that does the following:
1. Allows users to resolve paths carrying trailing period '.' characters.
2. Disallows users to create files carrying trailing period '.' characters.

Version 1 of the patch:
 https://lore.kernel.org/linux-fsdevel/20210818111123.19818-1-ddiss@xxxxxxx/

 Feedback will be appreciated.

 Thanks,
 Vasant

Vasant Karasulli (2):
  The "keep_last_dots" mount option will, in a subsequent commit,
    control whether or not trailing periods '.' are stripped from path
    components during file lookup or file creation.
  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:
