Mounting gocryptfs on login using pam_mount
|
|
||||||
===========================================
|
|
||||||
|
|
||||||
This works on Fedora 24 with active SELinux. Feedback on other platforms
|
|
||||||
is welcome.
|
|
||||||
|
|
||||||
gocryptfs
|
|
||||||
---------
|
|
||||||
|
|
||||||
Copy the `gocryptfs` binary and `gocryptfs_pam_mount.bash` into
|
|
||||||
`/usr/local/bin` .
|
|
||||||
|
|
||||||
The bash wrapper is neccessary because of the different calling
|
|
||||||
conventions between pam_mount and gocryptfs.
|
|
||||||
|
|
||||||
Create a gocryptfs filesystem:
|
|
||||||
```
|
|
||||||
$ mkdir /home/testuser/cipher /home/testuser/plain
|
|
||||||
$ gocryptfs -init /home/testuser/cipher
|
|
||||||
```
|
|
||||||
|
|
||||||
pam_mount config
|
|
||||||
----------------
|
|
||||||
|
|
||||||
Put the following into `/etc/security/pam_mount.conf.xml`, just before
|
|
||||||
the closing `</pam_mount>` tag at the bottom:
|
|
||||||
|
|
||||||
```
|
|
||||||
<volume user="testuser" fstype="fuse" options="defaults"
|
|
||||||
path="/usr/local/bin/gocryptfs_pam_mount.bash#/home/%(USER)/cipher"
|
|
||||||
mountpoint="/home/%(USER)/plain" />
|
|
||||||
```
|
|
||||||
|
|
||||||
Replace `testuser` with your user name.
|
|
||||||
|
|
||||||
If you want to disable the display of the masterkey on mount, replace
|
|
||||||
`options="defaults"` with `options="quiet"`.
|
|
||||||
|
|
||||||
PAM config
|
|
||||||
----------
|
|
||||||
|
|
||||||
An example `/etc/pam.d/login` on Fedora 24 is shown below. pam_mount
|
|
||||||
MUST be called AFTER `pam_selinux.so open` because that puts us in the
|
|
||||||
right SELinux context. If are logging in via gcm, also add the line in
|
|
||||||
`/etc/pam.d/gdm-password`.
|
|
||||||
|
|
||||||
```
|
|
||||||

|
||||||
auth substack system-auth
|
|
||||||

|
|
||||||

|
|
||||||

|
|
||||||

|
|
||||||

|
|
||||||

||||||

|
|
||||||

|
||||||

|

||||||

|
|
||||||
# ^^^ insert pam_mount here
|
|
||||||

|
|
||||||
session include system-auth
|
|
||||||
session include postlogin
|
|
||||||
-session optional pam_ck_connector.so
|
|
||||||
```
|
|
||||||
|
|
||||||
Encrypting the whole home directory
|
|
||||||
-----------------------------------
|
|
||||||
|
|
||||||
Use this volume definition in `/etc/security/pam_mount.conf.xml`:
|
|
||||||
|
|
||||||
```
|
|
||||||
<volume user="testuser-whole-home" fstype="fuse" options="nonempty,allow_other"
|
|
||||||
path="/usr/local/bin/gocryptfs_pam_mount.bash#/home/%(USER).cipher"
|
|
||||||
mountpoint="/home/%(USER)" />
|
|
||||||
```
|
|
||||||
|
|
||||||
Replace `testuser-whole-home` with your user name.
