Subject: Bug in mntent.c: whitespace characters are not escaped
Hello,
The musl implementation of getmntent does not handle octal escape sequences
as the manual getmntent(3) says:
> Since fields in the mtab and fstab files are separated by
> whitespace, octal escapes are used to represent the characters
> space (\040), tab (\011), newline (\012), and backslash (\\) in
> those files when they occur in one of the four strings in a
> mntent structure. The routines addmntent() and getmntent() will
> convert from string representation to escaped representation and
> back. When converting from escaped representation, the sequence
> \134 is also converted to a backslash.
(See resulting bug <https://github.com/libfuse/libfuse/issues/634>.)
Best,
Daniel Gerber
