Subject: [PATCH 00/58] LSM: Module stacking for AppArmor
Date: Fri, 31 May 2019 16:09:22 -0700 [thread overview]
Message-ID: <20190531231020.628-1-casey@schaufler-ca.com> (raw)
This patchset provides the changes required for
the AppArmor security module to stack safely with any other.
A new process attribute identifies which security module
information should be reported by SO_PEERSEC and the
/proc/.../attr/current interface. This is provided by
/proc/.../attr/display. Writing the name of the security
module desired to this interface will set which LSM hooks
will be called for this information. The first security
module providing the hooks will be used by default.
The use of integer based security tokens (secids) is
generally (but not completely) replaced by a structure
lsm_export. The lsm_export structure can contain information
for each of the security modules that export information
outside the LSM layer.
The LSM interfaces that provide "secctx" text strings
have been changed to use a structure "lsm_context"
instead of a pointer/length pair. In some cases the
interfaces used a "char *" pointer and in others a
"void *". This was necessary to ensure that the correct
release mechanism for the text is used. It also makes
many of the interfaces cleaner.
