apparmor: constify aa_profile parameters on read-only compute paths

2026-08-11T05:49:43+00:00

A number of functions take a struct aa_profile * argument that is only
ever read from: they compute DFA matches or apply the profile's mode
flags without modifying the profile, taking a reference on it, or
touching its embedded label. Mark those parameters const struct
aa_profile * to document intent and let the compiler enforce it.

The converted functions are the permission "compute" path plus a few
pure readers:
  - aa_apply_modes_to_perms(), aa_profile_match_label()
  - AUDIT_MODE()
  - aa_label_match() and its match_component()/label_compound_match()/
    label_components_match() helpers (label.c)
  - match_component()/label_compound_match()/label_components_match()/
    label_match()/change_profile_perms()/aa_xattrs_match() (domain.c)
  - match_iface()/match_addr_iface()/match_addr_iface_label()/
    skb_match_to_sk()/skb_match_to_cmd() (af_inet.c)
  - aa_profile_capget(), path_flags(), profile_query_cb()

The remaining aa_profile * parameters cannot be made const: the audit
path stores &profile->label into the owned, refcounted
apparmor_audit_data.subj_label/peer fields, and the domain/lifecycle
paths take references on the profile's embedded label
(aa_get_label()/aa_get_newest_label()/aa_get_profile()) or write
profile fields.

No functional change.

apparmor: make include headers self-contained

2026-06-29T17:26:36+00:00

Besides of resolving clangd IDE warnings, self-contained headers will be
less likely to break if the surrounding includes in .c files using them
change.

apparmor: add ability to mediate caps with policy state machine

2025-01-18T14:47:12+00:00

Currently the caps encoding is very limited and can't be used with
conditionals. Allow capabilities to be mediated by the state
machine. This will allow us to add conditionals to capabilities that
aren't possible with the current encoding.

This patch only adds support for using the state machine and retains
the old encoding lookup as part of the runtime mediation code to
support older policy abis. A follow on patch will move backwards
compatibility to a mapping function done at policy load time.

apparmor: pass cred through to audit info.

2023-10-18T22:30:38+00:00

The cred is needed to properly audit some messages, and will be needed
in the future for uid conditional mediation. So pass it through to
where the apparmor_audit_data struct gets defined.

LSM: generalize flag passing to security_capable

2019-01-10T22:16:06+00:00

This patch provides a general mechanism for passing flags to the
security_capable LSM hook. It replaces the specific 'audit' flag that is
used to tell security_capable whether it should log an audit message for
the given capability check. The reason for generalizing this flag
passing is so we can add an additional flag that signifies whether
security_capable is being called by a setid syscall (which is needed by
the proposed SafeSetID LSM).

prefixes are used for fns/data that are not static to apparmorfs.c
with the prefixes being
  aafs   - special magic apparmorfs for policy namespace data
  aa_sfs - for fns/data that go into securityfs
  aa_fs  - for fns/data that may be used in the either of aafs or
           securityfs

Mediation is based off of the cred but auditing includes the current
