Unable to change directories when exposed via Mina SFTP

[ptirador]

Task Description

When using S3FS as a file system for Mina SFTP, it's not possible to change the directory (cd command):

sftp> ls -l
d---------   1 OWNER@   GROUP@          0 Jan 25 10:51 bar
d---------   1 OWNER@   GROUP@          0 Jan 25 10:42 foo
sftp> cd foo
Can't change directory: Can't check target

POSIX permissions are not being returned for these directories, which is causing an exception in the SFTP client when attempting to cd to the directory.

Tasks

The following tasks will need to be carried out:

• When getting S3 Posix File Attributes in S3Utils, if the path is a directory, obtain the bucket ACL, then obtain its ACL grant permissions, convert them to Posix file permissions and return them with the response.
