[PATCH v2 17/25] LSM: Use lsmcontext in security_secid_to_secctx
Casey Schaufler
casey at schaufler-ca.com
Tue Jun 18 23:05:43 UTC 2019
Replace the (secctx,seclen) pointer pair with a single
lsmcontext pointer to allow return of the LSM identifier
along with the context and context length. This allows
security_release_secctx() to know how to release the
context. Callers have been modified to use or save the
returned data from the new structure.
