bc62ec6034Audit formats denial records with per-right name strings. A following
commit adds trace events that print the same access and scope masks with
__print_flags() and need the same names, but a trace event header cannot
include Landlock-internal headers, so the names cannot be shared from
the logging unit.
Define the filesystem, network, and scope names once, as the
_LANDLOCK_ACCESS_FS_NAMES, _LANDLOCK_ACCESS_NET_NAMES, and
_LANDLOCK_SCOPE_NAMES lists in the public Landlock header. Each entry
is a _LANDLOCK_NAME_ENTRY() the consumer expands: audit maps it to a
"[bit] = name" array slot for an O(1) lookup, the trace events map it to
a __print_flags() { mask, name } pair. The bit value comes only from
the LANDLOCK_* UAPI constant each entry references, so every bit-to-name
mapping has a single source and does not depend on entry order.
The shared names are unprefixed; blocker_prefix() prepends the
fs./net./scope. category for audit records, so the scope names move from
inline literals to the shared table too. Audit records are unchanged.
No functional change.
