Support SSH agent forwarding |
| 9 |
|
| 10 |
When using SSH agent forwarding, the SSH daemon creates the necessary |
| 11 |
sockets somewhere in a random /tmp/ssh-* location. These sockets get the |
| 12 |
sshd_tmp_t type associated. |
| 13 |
|
| 14 |
Currently, the SSH client (running as ssh_t) does not have any |
| 15 |
privileges on sshd_tmp_t *socket* files, but it has manage rights on the |
| 16 |
*regular* files. This means that any attempt to make use of the agent |
| 17 |
forwarding (i.e. from the logged-in server, attempt to SSH to another |
| 18 |
server while using the SSH agent running on the users' workstation) will |
| 19 |
fail. |
| 20 |
|
| 21 |
By granting rw_socket_file_perms permissions to ssh_t against the |
| 22 |
sshd_tmp_t socket files, agent forwarding is working well. |
