Mike Salvatore 17111037fd apparmor: reset pos on failure to unpack for various functions ... [ Upstream commit 156e42996bd84eccb6acf319f19ce0cb140d00e3 ] Each function that manipulates the aa_ext struct should reset it's "pos" member on failure. This ensures that, on failure, no changes are made to the state of the aa_ext struct. There are paths were elements are optional and the error path is used to indicate the optional element is not present. This means instead of just aborting on error the unpack stream can become unsynchronized on optional elements, if using one of the affected functions.
