Rework the general infrastructure around RANDOM_KMALLOC_CACHES into more
flexible PARTITION_KMALLOC_CACHES, with the former being a partitioning
mode of the latter.
Introduce a new mode, TYPED_KMALLOC_CACHES, which leverages a feature
available in Clang 22 and later, called "allocation tokens" via
__builtin_infer_alloc_token [1]. Unlike RANDOM_KMALLOC_CACHES, this mode
deterministically assigns a slab cache to an allocation of type T,
regardless of allocation site.
The builtin __builtin_infer_alloc_token(<malloc-args>, ...) instructs
the compiler to infer an allocation type from arguments commonly passed
to memory-allocating functions and returns a type-derived token ID. The
implementation passes kmalloc-args to the builtin: the compiler performs
best-effort type inference, and then recognizes common patterns such as
`kmalloc(sizeof(T), ...)`, `kmalloc(sizeof(T) * n, ...)`, but also
`(T *)kmalloc(...)`. Where the compiler fails to infer a type the
fallback token (default: 0) is chosen.
Note: kmalloc_obj(..) APIs fix the pattern how size and result type are
expressed, and therefore ensures there's not much drift in which
patterns the compiler needs to recognize. Specifically, kmalloc_obj()
and friends expand to `(TYPE *)KMALLOC(__obj_size, GFP)`, which the
compiler recognizes via the cast to TYPE*.
Clang's default token ID calculation is described as [1]:
typehashpointersplit: This mode assigns a token ID based on the hash
of the allocated type's name, where the top half ID-space is reserved
for types that contain pointers and the bottom half for types that do
not contain pointers.
Separating pointer-containing objects from pointerless objects and data
allocations can help mitigate certain classes of memory corruption
exploits [2]: attackers who gains a buffer overflow on a primitive
buffer cannot use it to directly corrupt pointers or other critical
metadata in an object residing in a different, isolated heap region.
It is important to note that heap isolation strategies offer a
best-effort approach, and do not provide a 100% security guarantee,
albeit achievable at relatively low performance cost. Note that this
also does not prevent cross-cache attacks, and SLAB_VIRTUAL [3] should
be used as a complementary mitigation (once available).
With all that, my kernel (x86 defconfig) shows me a histogram of slab
cache object distribution per /proc/slabinfo (after boot):
<slab cache> <objs> <hist>

kmalloc-part-03 276 ++
kmalloc-part-02 283 ++
kmalloc-part-01 316 +++
kmalloc 1599 +++++++++++++++
The above /proc/slabinfo snapshot shows me there are 6943 allocated
objects (slabs 00 - 07) that the compiler claims contain no pointers or
it was unable to infer the type of, and 11900 objects that contain
pointers (slabs 08 - 15). On a whole, this looks relatively sane.
Additionally, when I compile my kernel with -Rpass=alloc-token, which
provides diagnostics where (after dead-code elimination) type inference
failed, I see 179 allocation sites where the compiler failed to identify
a type (down from 966 when I sent the RFC [4]). Some initial review
confirms these are mostly variable sized buffers, but also include
structs with trailing flexible length arrays.

So this is clearly a minor defect in this existing code (comment wrong
or code might want to match what the comment said), but "slab: support
for compiler-assisted type-based slab cache partitioning" didn't touch
that.

Oh, crud. It turns out that for this check Smatch allows
integer_array[sizeof()]so long as we know that the index is within
bounds. What happened is that your patch renamed the kmalloc()
function so Smatch stopped knowing the size of the buffer.
For these zero day bot warnings, the emails are automatically generated
so I don't have any context outside what's in the email. I saw that
Kees wrote the code, but I figured maybe you forwarded it or something.
Sorry about that.

Oh, I see. Smatch doesn't respect the __alloc_size attribute then?

So the @token parameter is unused when CONFIG_PARTITION_KMALLOC_CACHES is
disabled but still increases the kernel size by a few kilobytes...
but yeah I'm not sure if we can get avoid it without hurting readability.
Just saying. (does anybody care?)

Assuming not all people building the kernel are security experts...
(including myself) could you please add some insights/guidance on how to
decide between RANDOM_KMALLOC_CACHES and TYPED_KMALLOC_CACHES?
Something like what Florent wrote [1]:
| One more perspective on this: in a data center environment, attackers
| typically get a first foothold by compromising a userspace network
| service. If they can do that once, they can do that a bunch of times,
| and gain code execution on different machines every time.
|
| Before trying to exploit a kernel memory corruption to elevate
| privileges on a machine, they can test the SLAB properties of the
| running kernel to make sure it's as they wish (eg: with timing side
| channels like in the SLUBStick paper). So with RANDOM_KMALLOC_CACHES,
| attackers can just keep retrying their attacks until they land on a
| machine where the types T and S are collocated and only then proceed
| with their exploit.
|
| With TYPED_KMALLOC_CACHES (and with SLAB_VIRTUAL hopefully someday),
| they are simply never able to cross the "objects without pointers" to
| "objects with pointers" boundary which really gets in the way of many
| exploitation techniques and feels at least to me like a much stronger
| security boundary.
|
| This limit of RANDOM_KMALLOC_CACHES may not be as relevant in other
| deployments (eg: on a smartphone) but it makes me strongly prefer
| TYPED_KMALLOC_CACHES for server use cases at least.

Otherwise the patch is really straightforward and looks good to me.
Thanks!

Now somewhat out-of-scope (or at least pre-existing) review comments
from Sashiko that I think are still worth mentioning...

Sashiko pointed out KMALLOC_CGROUP caches are not partitioned [1]:
| Do allocations with the __GFP_ACCOUNT flag completely bypass typed
| and random partitioning? KMALLOC_NOT_NORMAL_BITS includes __GFP_ACCOUNT.
Right.
| If this bit is set, the code bypasses the partitioning logic and routes
| the allocation to the KMALLOC_CGROUP cache.
Right.
| Since user-controllable objects
| like msg_msg, file descriptors, and pipes are allocated with __GFP_ACCOUNT,
Right.
| they will all be clustered in the exact same unpartitioned cache.
Right.
From security perspective do you think it'd be worthwhile to partition
KMALLOC_CGROUP caches? (I see at least few hundreds of users, unlike
KMALLOC_RECLAIM where there are only few users).
Another valid concern from Sashiko [1]:
| Does this leave reallocation functions like krealloc() and kvrealloc()
| without allocation token propagation?
|
| When an object is reallocated and requires memory expansion, the underlying
| generic SLUB code allocates a new buffer. Because the token macro is not
| applied to these realloc paths, __builtin_infer_alloc_token() evaluates
| locally on a generic size_t variable rather than the original type.
I think this is a valid point and worth addressing.
| This causes it to return the fallback token (0), which silently migrates the
| object from its isolated typed cache to the shared fallback cache
| (kmalloc-part-00) when resized.

Well we did care enough with CONFIG_SLAB_BUCKETS to hide the unused param
using DECL_BUCKET_PARAMS(), so maybe extend that idea?
I think it's not just kernel size, but increased register pressure etc.

Hmm yeah.
I wasn't sure if we could do this without hurting readability,
but perhaps we could...

Something like this should work? (diff on top of this patch)

You can find different arguments for either, and in the original RFC
that was part of the discussion. However, my biased view is that
type-based partitioning in general is the stronger security boundary.
Because it creates a deterministic separation; specifically isolating
pointer-containing objects from pointerless ones: it effectively kills
certain classes of exploit techniques that probabilistic defenses
(like randomization) only delay, especially in environments where
attackers can retry or use side-channels.
The current pointer/non-pointer scheme is relatively intuitive with
well-understood properties, and a good start. However, an open
research question is if better alloc-token ID schemes exist: one that
is tailored to kernel data structures that would meaningfully increase
exploitation difficulty further without increasing the number of
partitions. Since an improved scheme could simply be activated with a
compiler flag, having the baseline infrastructure available and
maintained is the first step.

Indeed, these are pre-existing issues with RANDOM_KMALLOC_CACHES.
Worth follow-up patches, but this patch here wants to just get the
TYPED_KMALLOC_CACHES infrastructure in place so we can build on top of
it.

Not sure if it's safe to do that for exported functions though (since
modules can be built w/ a different compiler).

That's a fair argument.
Could we possibly put some of those arguments (in a neutral/technical
sense) in help text to make people's lives easier?
Err, trying to provide unbiased (tm) help text...
Something like:
config RANDOM_KMALLOC_CACHES
bool "Randomize slab caches for normal kmalloc"
help
Randomly pick a slab cache based on code address and a per-boot
random seed.
This makes it harder for attackers to predict object co-location.
The placement is random: while attackers don't know which kmalloc
cache an object will be allocated from, they might circumvent
the randomization by retrying attacks across multiple machines until
the target objects are co-located.
config TYPED_KMALLOC_CACHES
bool "Type based slab cache selection for normal kmalloc"
depends on $(cc-option,-falloc-token-max=123)
help
Rely on Clang's allocation tokens to choose a slab cache, where token
IDs are derived from the allocated type.
Unlike RANDOM_KMALLOC_CACHES, the cache assignment is deterministic
and based on type, which guarantees that objects of certain types
are not placed in the same cache. This effectively mitigates
certain classes of exploits that probabilistic defenses like
RANDOM_KMALLOC_CACHES only make harder but not impossible.
However, this also means the cache assignment is predictable.
For example, a token ID scheme might separate pointer-containing
objects and pointerless objects to prevent buffer overflows on
primitive buffers from directly corrupting pointer-containing objects.
The current effectiveness of Clang's type inference can be judged by
-Rpass=alloc-token, which provides diagnostics where (after dead-code
elimination) type inference failed.
Requires Clang 22 or later.

So I checked with Clang and GCC. Looks like Clang does omit the
zero-sized struct argument, i.e. generated code is identical to
before. Whereas GCC wastes a few bytes of stack space at callsites.
Which is sad, because that means we need the macro workaround.
Do you want to be credited with Co-authored-by - in which case I need
your Signed-off-by.

Kernel modules built with a different config (implicit if different
compiler) are not supported, and never have been. If it works, it's
just luck (I know people do this, but it's just a disaster waiting to
happen).

And if GCC folks somehow fix this at some point, even kernel modules
built with a different version of GCC might not be supported?

Yes, and different compiler version also implies different compiler
(so even GCC A.B != GCC X.Y), because newer compiler versions may
activate different codegen options (some of which we auto-enable if
available).

One tiny suggestion: we could use the same name for kmalloc_token_t's
member in both cases, which would make the code a bit more concise.
