Moving the use of fqname to later allows learning profiles to be based on the fqname request instead of just the hname. It also allows cleaning up some of the name parsing and lookup by allowing the use of the fqlookupn_profile() lib fn. Signed-off-by: John Johansen <john.johansen@canonical.com>

The aad macro can replace aad strings when it is not intended to. Switch to a fn macro so it is only applied when intended. Also at the same time cleanup audit_data initialization by putting common boiler plate behind a macro, and dropping the gfp_t parameter which will become useless.

Having ops be an integer that is an index into an op name table is awkward and brittle. Every op change requires an edit for both the op constant and a string in the table. Instead switch to using const strings directly, eliminating the need for the table that needs to be kept in sync. Signed-off-by: John Johansen <john.johansen@canonical.com>

Trying to update the task cred while the task current cred is not the real cred will result in an error at the cred layer. Avoid this by failing early and delaying the update. Signed-off-by: John Johansen <john.johansen@canonical.com>

Verify that profiles in a load set specify the same policy ns and audit the name of the policy ns that policy is being loaded for. Signed-off-by: John Johansen <john.johansen@canonical.com>

Store loaded policy and allow introspecting it through apparmorfs. This has several uses from debugging, policy validation, and policy checkpoint and restore for containers. Signed-off-by: John Johansen <john.johansen@canonical.com>

Policy management will be expanded beyond traditional unconfined root. This will require knowning the profile of the task doing the management and the ns view. Signed-off-by: John Johansen <john.johansen@canonical.com>

Prepare for a tighter pairing of user namespaces and apparmor policy namespaces, by making the ns to be viewed available. Signed-off-by: John Johansen <john.johansen@canonical.com>
-
John Johansen authored
Prepare for a tighter pairing of user namespaces and apparmor policy namespaces, by making the ns to be viewed available and checking that the user namespace level is the same as the policy ns level. This strict pairing will be relaxed once true support of user namespaces lands. Signed-off-by: John Johansen <john.johansen@canonical.com>

Commit 9f834ec1 ("binfmt_elf: switch to new creds when switching to new mm") changed when the creds are installed by the binfmt_elf handler. This affects which creds are used to mmap the executable into the address space. Which can have an affect on apparmor policy. Add a flag to apparmor at /sys/kernel/security/apparmor/features/domain/fix_binfmt_elf_mmap to make it possible to detect this semantic change so that the userspace tools and the regression test suite can correctly deal with the change.

Instead of testing whether a given dfa exists in every code path, have a default null dfa that is used when loaded policy doesn't provide a dfa. This will let us get rid of special casing and avoid dereference bugs when special casing is missed. Signed-off-by: John Johansen <john.johansen@canonical.com>
-
John Johansen authored
Newer policy will combine the file and policydb dfas, allowing for better optimizations. However to support older policy we need to keep the ability to address the "file" dfa separately. So dup the policydb as if it is the file dfa and set the appropriate start state. Signed-off-by: John Johansen <john.johansen@canonical.com>

The dfa is currently setup to be shared (has the basis of refcounting) but currently can't be because the count can't be increased. Signed-off-by: John Johansen <john.johansen@canonical.com>

Newer policy encodes more than just version in the version tag, so add masking to make sure the comparison remains correct. Note: this is fully compatible with older policy as it will never set the bits being masked out. Signed-off-by: John Johansen <john.johansen@canonical.com>
