added Update the policy version (POLICYDB_VERSION_CONSTRAINT_NAMES) to allow holding of policy source info for constraints. Upstream commit a660bec1d84ad19a39e380af129e207b3b8f609e Bug: 20350607 Signed-off-by: Richard Haines <richard_c_haines@btinternet.com> Acked-by: Stephen Smalley <sds@tycho.nsa.gov> Signed-off-by: Paul Moore <pmoore@redhat.com> Change-Id: If419c7bfdea2f7006c9a62ea595f0cbfe5c78871
note that this patch depends on a prior patch that is already in android-3.4 but has not apparently found its way into the msm 3.4 branches (but is included in exynos and tegra), https://android-review.googlesource.com/#/c/92962/ Extend the generic ioctl permission check with support for per-command filtering. Source/target/class sets including the ioctl permission may additionally include a set of commands. Example: allow <source> <target>:<class> { 0x8910-0x8926 0x892A-0x8935 } auditallow <source> <target>:<class> 0x892A When ioctl commands are omitted only the permissions are checked. This feature is intended to provide finer granularity for the ioctl permission which may be too imprecise in some circumstances. For example, the same driver may use ioctls to provide important and benign functionality such as driver version or socket type as well as dangerous capabilities such as debugging features, read/write/execute to physical memory or access to sensitive data. Per-command filtering provides a mechanism to reduce the attack surface of the kernel, and limit applications to the subset of commands required. The format of the policy binary has been modified to include ioctl commands, and the policy version number has been incremented to POLICYDB_VERSION_IOCTL_OPERATIONS=30 to account for the format change.
