autofs-5.1.2 - honor last rw in mount options when doing a bind mount

From: David Jeffery <djeffery@redhat.com>

mount(8) will use the last ro/rw option in its options list.
|
|
|
306fa1 |
e.g. "mount -o ro,rw" will make a read-write mount while
|
|
|
306fa1 |
"mount -o rw,ro" will make a read-only mount.
|
|
|
306fa1 |
|
|
|
306fa1 |
The patch changes the option parsing for mount_mount() in
|
|
|
306fa1 |
modules/mount_nfs.c to clear the ro variable when a "rw"
|
|
|
306fa1 |
option is seen. This will handle occurrences of both "ro"
|
|
|
306fa1 |
and "rw" options, resulting in a read-only option being
|
|
|
306fa1 |
passed to a bind mount only if the option order would also
|
|
|
306fa1 |
have resulted in an nfs mount being read-only.
