Unpopulated addresses within +the range remain unpopulated; when first accessed they fault through the +normal missing path (``do_anonymous_page()``, ``do_swap_page()``, +``finish_fault()``) and the resulting PTE is not RWP-protected. To observe +the population itself, co-register the range with +``UFFDIO_REGISTER_MODE_MISSING``. + +Protection is preserved across page reclaim: a page swapped out while +RWP-protected carries the marker on its swap entry, and swap-in restores +the PROT_NONE state so the first access after swap-in still faults. The +same applies to pages temporarily replaced by migration entries. + +Operations that drop the PTE entirely — ``MADV_DONTNEED`` on anonymous +memory, hole-punch on shmem, truncation of a file mapping — also drop the +RWP marker: the next access re-populates the range without protection. +Unlike WP (which persists via ``PTE_MARKER_UFFD_WP``), there is no +persistent RWP marker today.

SPDX-License-Identifier: GPL-2.0 + +============ +BPF signing +============ + +This document describes how BPF programs are cryptographically signed, how the +kernel verifies them at load time, and how Linux Security Modules (LSMs) - +including the BPF LSM - use the resulting verdict to enforce policy. It is +written for developers who want to produce signed BPF objects, understand what +the signature actually guarantees, or build a policy on top of it. + +Motivation +========== + +A signed BPF program lets the kernel establish that the bytecode being loaded +originates from a trusted producer and was not modified in transit. On its own +the kernel does not *require* signatures - an unsigned program loads exactly as +before - but it records a verdict (see `The verdict`_) that an LSM can gate on. +This is the building block for policies such as "only run BPF that was signed by +a key in the trusted keyring", as could in the future be enforced by an LSM +such as IPE. + +Signing is orthogonal to the existing permission model: it does not replace the +capability checks or the verifier. A signed load still requires the usual +privileges (``CAP_BPF`` and any program-type-specific capability, subject to +``kernel.unprivileged_bpf_disabled``), and the loader's instructions are still +checked by the verifier like any other program. A valid signature establishes +*origin and integrity*, not safety - it lets a policy trust where the bytecode +came from, it does not let a load skip any check it would otherwise face. + +The hard part is *what* gets signed. A naive scheme would sign a program's +instruction buffer at build time and verify that signature at +``BPF_PROG_LOAD``. That does not survive contact with real BPF objects, because +the bytes the kernel finally loads are not the bytes the developer built and +signed. Between the two, libbpf and the kernel rewrite the program: + +- **map file descriptors** are patched into ``ld_imm64`` instructions + (``BPF_PSEUDO_MAP_FD``), and a map's fd is assigned at load time, so it + differs on every run; +- **CO-RE relocations** rewrite field offsets, sizes and existence flags against + the *running* kernel's BTF, so the result differs from one kernel to the next; +- **kfunc and ksym references** are resolved to ids/addresses in the running + kernel; +- **global data** (``.rodata``/``.data``/``.bss``) is created and seeded as maps + at load. + +So a signature over the original instructions cannot match the relocated +instructions the verifier ends up checking, and the relocated form cannot be +produced ahead of time because it depends on the target kernel. There is no +fixed byte string that is both signable at build time and what the kernel +actually loads - which is why a program cannot simply be signed and loaded +directly. + +The trusted loader +================== + +The solution is to move that setup work *into* a small BPF program - the +**loader** - and sign the loader instead of the individual programs. libbpf's +``gen_loader`` machinery (``bpftool gen skeleton -L``, the "light skeleton") +emits a ``BPF_PROG_TYPE_SYSCALL`` program whose body performs the bpf() syscalls +that create maps, apply relocations, and load the real programs. The payload it +installs - the serialized programs, map descriptions, relocation data and +initial values - lives in a separate array map, the **metadata map** +(``__loader.map``). + +So the unit of trust is the loader, and the signing contract is:: + + Sig(I_loader || D_meta) + +where ``I_loader`` is the loader's instruction stream and ``D_meta`` is the +content of the metadata map. Verifying the loader's signature establishes that +both the loader *and* the payload it is about to install are authentic. The +loader is reproducible: ``gen_loader`` builds it from primitives so the same +object yields the same bytes on any build host. + +Why the loader is signable when the program is not +-------------------------------------------------- + +The loader sidesteps every rewrite listed above, because the bytes that are +signed are *relocation-invariant*: + +- The loader's own instructions are a fixed sequence of bpf() syscalls emitted + by ``gen_loader``; they carry no CO-RE relocations and resolve no ksyms, so + they are identical on every kernel. The metadata map is referenced by *index* + into ``fd_array`` (``BPF_PSEUDO_MAP_IDX_VALUE``), not by a baked-in file + descriptor, so even that reference does not change between build and load. + The loader instruction bytes the kernel verifies are exactly the bytes that + were signed. +- The metadata map is opaque, frozen data - the serialized target programs, + their relocation records, map descriptions and initial values. Its bytes are + identical at build time and at load time, so they are simply appended to the + instructions and covered by the same signature (there is no separate metadata + hash to compute or compare). + +All the host-specific rewriting - creating maps, patching their fds into the +target programs, applying CO-RE, resolving ksyms, seeding global data - still +happens, but it happens *inside the loader at runtime*, on the verified +metadata, **after** the kernel has verified the ``insns || metadata`` signature. +The kernel never has to verify the relocated target programs: it verifies the +loader and its inputs once, and trust transfers to whatever that now-trusted, +deterministic loader installs. The relocation step is moved from "before the +signature can be checked" to "after a trusted program runs" - which is exactly +what makes it signable. + +Because the metadata map is the loader's only untrusted input, two existing map +properties are reused to keep it trustworthy across the load: + +Exclusive maps + A map created with ``excl_prog_hash`` (see ``BPF_MAP_CREATE``) may only be + accessed by a program whose digest matches that hash. The verifier enforces + ``map->excl_prog_sha == prog->digest`` for every map a program uses, so the + metadata map is bound to exactly the signed loader and cannot be shared with + or mutated by another program. + +Frozen maps + The metadata map is frozen (``BPF_MAP_FREEZE``) before the loader is loaded. + Freezing blocks further userspace writes, so the bytes folded into the + signature cannot change before the loader runs. (Freezing does not make the + map read-only to the loader program itself, which still writes created file + descriptors back into the blob's scratch area.) + +Load-time verification +======================= + +Rather than have the loader check its own metadata from within BPF, the kernel +verifies it directly at ``BPF_PROG_LOAD``, with no new UAPI. The mechanism +reuses the existing ``fd_array``: + +#. Userspace creates the metadata map with ``excl_prog_hash`` set to the + loader's digest, populates it, and freezes it. +#. The loader is loaded with ``signature``/``signature_size``/``keyring_id`` + set, the metadata map referenced through ``fd_array``, and ``fd_array_cnt`` + set so the kernel knows the array's length. +#. Signature verification runs inside the verifier (``bpf_check()``), once it + has resolved the ``fd_array`` entries into the program's ``used_maps``. The + maps folded into the signature are therefore the very objects the program + binds - a single resolution of ``fd_array``, not a separate read, so the + verified bytes cannot be swapped for a different map after the check (no + time-of-check/time-of-use window). Each folded map must be exclusive (carry + ``excl_prog_sha``) and a plain array map (``BPF_MAP_TYPE_ARRAY``); only an + array map exposes its value buffer through ``map_direct_value_addr()`` as a + kernel address spanning ``value_size`` bytes. A map that is not exclusive, not + frozen, or not a plain array is rejected, with a verifier log message naming + the offending map. The kernel appends each map's frozen + contents to the instruction buffer and verifies the PKCS#7 signature over the + concatenation ``insns || metadata_0 || metadata_1 || ...`` in ``used_maps`` + order, before it rewrites the (signed) instructions. + +A signed program therefore takes one of exactly two shapes, both fully +supported: + +- **No bound maps** (``fd_array_cnt == 0``): there is nothing to append, so the + kernel verifies the signature over the instructions alone. A valid signature + yields ``BPF_SIG_VERIFIED`` and the program loads. This is the ordinary case + for a directly-loaded signed program with no separate payload; it is *not* + rejected for "missing" metadata, because it has none to cover. +- **Exclusive bound maps** (``fd_array_cnt > 0``): every entry is exclusive and + folded, so the signature covers ``insns || metadata``. + +There is no third shape: a non-exclusive map in a signed program's ``fd_array`` +is rejected rather than silently left out of the signature, so a signed loader +never binds a map its signature does not cover. + +The digest binding (``excl_prog_sha == prog->digest``) is enforced by the +verifier as usual; because that check runs while ``fd_array`` is resolved - +before the verifier would otherwise compute the tag - ``prog->digest`` is +computed up front in the verifier, over the unmodified (signature-covered) +instructions, for any signed load. + +Coverage is then enforced as the verifier resolves instructions, at the point +each object is bound rather than by a count taken afterwards. Once the signature +has been verified, binding any further map is refused: a map reached by a +directly-referenced fd, or a map swapped into an ``fd_array`` slot the loader +reads, is not among those already folded, so it is rejected the moment the +verifier tries to bind it. A BTF is refused outright for a signed program - a +ksym or a BTF fd in ``fd_array``, whether resolved up front or lazily for a +module kfunc, is rejected when it would be bound. Together with the fold rule +above this keeps the verdict binary: a signed program cannot use a map its +signature does not cover, and a different but equally digest-bound map cannot be +substituted at an ``fd_array`` slot. Non-exclusive maps are never folded, so a +signed program cannot use one at all. + +The verdict +=========== + +A program is either unsigned or fully verified - there is no intermediate +state. The outcome is recorded in ``prog->aux->sig.verdict``: + +.. code-block:: c + + enum bpf_sig_verdict { + BPF_SIG_UNSIGNED = 0, + BPF_SIG_VERIFIED, + }; + +``BPF_SIG_VERIFIED`` means the signature is valid and covers the instructions +*and* the frozen contents of every exclusive map the program uses: + +- For an ordinary, directly-loaded signed program the instructions are the whole + artifact and it uses no exclusive maps, so a valid instruction signature is + the complete verification. +- For a signed loader the metadata map is exclusive, so its contents are folded + in and the signature covers ``insns || metadata``. + +There is deliberately no "instructions verified but metadata not" verdict: a +signed loader that fails to cover its metadata is *rejected* (see above), not +recorded with a weaker verdict. ``BPF_SIG_VERIFIED`` therefore always means the +program and everything the signature is responsible for are authentic, which is +what a policy can rely on. + +Alongside the verdict the kernel records which keyring validated the signature; +see `Keyrings`_. + +Enforcement via LSMs +==================== + +Signing only *records* a verdict; an LSM turns it into policy. The verdict and +keyring fields live in ``struct bpf_prog_aux``, so a BPF LSM program can read +them directly (see Documentation/bpf/prog_lsm.rst for writing and attaching BPF +LSM programs); the same fields are equally available to in-tree LSMs. Two hooks +are useful at different points of the load: the dedicated +``security_bpf_prog_load()`` gates admission before the main verification work, +and the existing ``security_bpf_prog()`` observes a program that has fully +loaded. + +Admission: ``security_bpf_prog_load()`` +--------------------------------------- + +This hook gates admission **for every load**, from a single call site inside the +verifier (``bpf_check()``), before the main verification work. It runs after the +optional signature verification, so the verdict and keyring fields are final - the +hook can see whether, and how strongly, the program was signed, which keyring +validated it, the load ``attr``, the BPF token and whether the load came from the +kernel. For a signed load the verdict is ``BPF_SIG_VERIFIED`` here (the signature +has just been checked); for an unsigned load it is ``BPF_SIG_UNSIGNED``. + +This is the place for *coarse admission* that must also see unsigned and +not-yet-verified loads: require a signature at all, restrict the acceptable +keyring, restrict which token/credentials may load BPF, apply per-program-type +rules, or audit every load attempt that makes it past signature verification - +attempts failing the signature or the metadata binding abort before this hook +fires. It is the primary deny point. + +One subtlety: this hook runs *before* the verifier finishes its work, so +``BPF_SIG_VERIFIED`` *here* means only "validly signed" - not "loaded". Allowing +a load at this point lets it *proceed*; it does not guarantee the program will +load. A validly signed program can still be rejected afterwards on two +independent grounds: the verifier may reject it like any other program (unsafe +memory access, bad control flow, resource limits, ...), and the kernel separately +refuses - as the verifier resolves instructions and binds each object - any map +the signature does not cover or any BTF at all, regardless of what this hook +returned. Only after the program has fully loaded, at the next hook +(``security_bpf_prog()``), does ``BPF_SIG_VERIFIED`` carry its full meaning: +validly signed *and* fully verified. + +A more realistic admission policy than "is it signed at all": accept programs +signed by a system keyring, accept a user-keyring signature only if the +key/keyring it was verified against is on an explicit allowlist, and emit a +tamper-evident record of every decision so that even denied attempts are +auditable. (Illustrative - error checking elided.) + +.. code-block:: c + + /* Serials of user keys/keyrings we additionally trust. */ + struct { + __uint(type, BPF_MAP_TYPE_HASH); + __type(key, __s32); /* keyring_serial */ + __type(value, __u8); + __uint(max_entries, 64); + } trusted_user_keys SEC(".maps"); + + /* Audit stream consumed by a userspace logger. */ + struct { + __uint(type, BPF_MAP_TYPE_RINGBUF); + __uint(max_entries, 1 << 16); + } audit SEC(".maps"); + + struct decision { __u32 prog_type, verdict, ktype; __s32 serial, ret; }; + + SEC("lsm/bpf_prog_load") + int BPF_PROG(admit, struct bpf_prog *prog, union bpf_attr *attr, + struct bpf_token *token, bool kernel) + { + __u32 verdict = prog->aux->sig.verdict; + __u32 ktype = prog->aux->sig.keyring_type; + __s32 serial = prog->aux->sig.keyring_serial; + struct decision *d; + int ret = 0; + + if (kernel) + return 0; /* trust in-kernel loads */ + + if (verdict != BPF_SIG_VERIFIED) + ret = -EPERM; /* must be validly signed */ + else if (ktype == BPF_SIG_KEYRING_USER && + !bpf_map_lookup_elem(&trusted_user_keys, &serial)) + ret = -EPERM; /* key/keyring not allowlisted */ + + d = bpf_ringbuf_reserve(&audit, sizeof(*d), 0); + if (d) { + d->prog_type = attr->prog_type; + d->verdict = verdict; + d->ktype = ktype; + d->serial = serial; + d->ret = ret; + bpf_ringbuf_submit(d, 0); /* record allow *and* deny */ + } + return ret; + } + +Observing a verified load: ``security_bpf_prog()`` +-------------------------------------------------- + +There is deliberately no separate "metadata attested" hook. The coverage check +above is enforced by the kernel unconditionally, so a signed loader that fails +to cover its metadata never loads and an LSM never has to re-establish that +fact. To *act on* a program that has successfully and fully loaded, use the +existing ``security_bpf_prog()`` hook (``lsm/bpf_prog``), which fires from +``bpf_prog_new_fd()`` - after the verifier, after the coverage check, and after +``bpf_prog_alloc_id()``. Relative to the admission hook this point is strictly +later and stronger: + +- the program has an id (``prog->aux->id``), so it can be recorded or correlated + with later events; +- ``verdict == BPF_SIG_VERIFIED`` *here* means **fully** verified - a program + that used a map the signature does not cover was already rejected, so it cannot + reach this point; +- it observes only programs that actually loaded; a failed load never mints an + fd, so it never reaches this hook. + +It takes only the ``prog`` and a non-zero return still aborts (the fd is not +handed out), so it can veto as well as observe. One wrinkle: it also fires on +other paths that mint a new program fd - notably ``bpf_prog_get_fd_by_id()`` - +not just on a fresh load. Because the program already has its id here, an LSM +can tell the two apart with a small hash map: the *first* time an id is seen is +the load; a later sighting of the same id is just another fd to a program that +already exists. + +To bound the map and let a reused id read as a fresh load, this can be paired +with ``security_bpf_prog_free()`` (``lsm/bpf_prog_free``), which deletes the +entry on teardown - keyed by the same ``prog`` pointer, since +``bpf_prog_free_id()`` has already cleared ``prog->aux->id`` to ``0`` by the time +that hook runs. (Illustrative - privileged LSM, error checking elided.) + +.. code-block:: c + + struct rec { __u32 id, ktype; __s32 serial; }; + + struct { + __uint(type, BPF_MAP_TYPE_HASH); + __type(key, __u64); /* struct bpf_prog * -- stable id */ + __type(value, struct rec); + __uint(max_entries, 4096); + } live SEC(".maps"); + + SEC("lsm/bpf_prog") /* fires after load and on every later fd */ + int BPF_PROG(observe, struct bpf_prog *prog) + { + __u64 key = (__u64)(unsigned long)prog; + struct rec r; + + if (prog->aux->sig.verdict != BPF_SIG_VERIFIED) + return 0; + if (bpf_map_lookup_elem(&live, &key)) + return 0; /* seen before: a later fd, not a load */ + + /* First sighting == this program just loaded; id is valid here. */ + r.id = prog->aux->id; + r.ktype = prog->aux->sig.keyring_type; + r.serial = prog->aux->sig.keyring_serial; + bpf_map_update_elem(&live, &key, &r, BPF_NOEXIST); + /* ... newly-loaded verified-program action, e.g. record r.id ... */ + return 0; + } + +Putting them together: to *require* verified BPF, deny at the admission hook +unless the verdict is ``BPF_SIG_VERIFIED`` (and, if desired, restrict the +keyring). The kernel then guarantees that any program which actually loads with +that verdict covered all of its exclusive maps, rejecting any that did not - so +a deny-by-default admission policy needs no second enforcement point. Use +``security_bpf_prog()`` to record or finally gate the verified programs once +they carry an id. The ``verdict``, ``keyring_type`` and ``keyring_serial`` fields +let a policy distinguish, for example, "verified and signed by a builtin key" +from "verified by a user key". A policy LSM such as IPE could consume the same +hooks to enforce system policy without writing any BPF, though none implements +this today. + +Keyrings +======== + +``keyring_id`` selects the trusted keyring the PKCS#7 signature is verified +against. The well-known ids ``0`` (builtin), ``VERIFY_USE_SECONDARY_KEYRING`` +and ``VERIFY_USE_PLATFORM_KEYRING`` select the corresponding system keyrings; +any other value is treated as the serial of a user/session key or keyring. +The keyring is looked up first, before the signature bytes are examined, so a +signature naming a non-existent keyring is rejected up front, and a failed +verification aborts the load - so a program that loads successfully with a +signature always has consistent keyring fields recorded. + +Two fields are recorded in ``prog->aux->sig`` for an LSM to inspect: + +``keyring_type`` (``enum bpf_sig_keyring``) + Classified purely from ``keyring_id`` whenever the program is signed: + ``BPF_SIG_KEYRING_BUILTIN``, ``_SECONDARY``, ``_PLATFORM`` for the system + keyrings, or ``_USER`` for a user/session keyring. It is + ``BPF_SIG_KEYRING_NONE`` for an unsigned program. + +``keyring_serial`` (``s32``) + Set **only** on a successful verification, to the serial of the + **user/session key or keyring** that ``keyring_id`` resolved to - the + object the signature was verified against, not the individual asymmetric + key inside it that matched the signer. Passing + ``KEY_SPEC_SESSION_KEYRING``, for example, records the session keyring's + serial. The system keyrings are trusted as a whole and expose no serial + here, so the serial is ``0`` for builtin, secondary and platform + signatures, and ``0`` for unsigned programs.
