Power management updates for 6.12-rc4
- Enable ACPI CPPC in amd_pstate_register_driver() after disabling it
in amd_pstate_unregister_driver() when switching driver operation
modes (Dhananjay Ugwekar).
- Make amd-pstate use nominal performance as the maximum performance
level when boost is disabled (Mario Limonciello).
- Add ArrowLake-H to the list of processors where PL4 is supported
in the MSR part of the intel_rapl power capping driver (Srinivas
Pandruvada).

mm: fix follow_pfnmap API lockdep assert
The lockdep asserts for the new follow_pfnmap() API "knows" that a
pfnmap always has a vma->vm_file, since that's the only way to create
such a mapping.
And that's actually true for all the normal cases. But not for the mmap
failure case, where the incomplete mapping is torn down and we have
cleared vma->vm_file because the failure occured before the file was
linked to the vma.
So this codepath does actually need to check for vm_file being NULL.

cdrom: Avoid barrier_nospec() in cdrom_ioctl_media_changed()
The barrier_nospec() after the array bounds check is overkill and
painfully slow for arches which implement it.
Furthermore, most arches don't implement it, so they remain exposed to
Spectre v1 (which can affect pretty much any CPU with branch
prediction).
Instead, clamp the user pointer to a valid range so it's guaranteed to
be a valid array index even when the bounds check mispredicts.

lib/buildid: Handle memfd_secret() files in build_id_parse()
>From memfd_secret(2) manpage:
The memory areas backing the file created with memfd_secret(2) are
visible only to the processes that have access to the file descriptor.
The memory region is removed from the kernel page tables and only the
page tables of the processes holding the file descriptor map the
corresponding physical memory. (Thus, the pages in the region can't be
accessed by the kernel itself, so that, for example, pointers to the
region can't be passed to system calls.)
We need to handle this special case gracefully in build ID fetching
code. Return -EFAULT whenever secretmem file is passed to build_id_parse()
family of APIs. Original report and repro can be found in [0].

ipe: allow secondary and platform keyrings to install/update policies
The current policy management makes it impossible to use IPE in a general purpose distribution. In such cases the users are not building the kernel, the distribution is, and access to the private key included in the trusted keyring is, for obvious reason, not available. This means that users have no way to enable IPE, since there will be no built-in generic policy, and no access to the key to sign updates validated by the trusted keyring. Just as we do for dm-verity, kernel modules and more, allow the secondary and platform keyrings to also validate policies. This allows users enrolling their own keys in UEFI db or MOK to also sign policies, and enroll them. This makes it sensible to enable IPE in general purpose distributions, as it becomes usable by any user wishing to do so. Keys in these keyrings can already load kernels and kernel modules, so there is no security downgrade. Add a kconfig each, like dm-verity does, but default to enabled if the dependencies are available.

ipe: also reject policy updates with the same version
Currently IPE accepts an update that has the same version as the policy being updated, but it doesn't make it a no-op nor it checks that the old and new policyes are the same. So it is possible to change the content of a policy, without changing its version. This is very confusing from userspace when managing policies. Instead change the update logic to reject updates that have the same version with ESTALE, as that is much clearer and intuitive behaviour.

nvme: make keep-alive synchronous operation
The nvme keep-alive operation, which executes at a periodic interval,
could potentially sneak in while shutting down a fabric controller.
This may lead to a race between the fabric controller admin queue
destroy code path (invoked while shutting down controller) and hw/hctx
queue dispatcher called from the nvme keep-alive async request queuing
operation. This race could lead to the kernel crash shown below:
Call Trace:
autoremove_wake_function+0x0/0xbc (unreliable)
__blk_mq_sched_dispatch_requests+0x114/0x24c
blk_mq_sched_dispatch_requests+0x44/0x84
blk_mq_run_hw_queue+0x140/0x220
nvme_keep_alive_work+0xc8/0x19c [nvme_core]
process_one_work+0x200/0x4e0
worker_thread+0x340/0x504
kthread+0x138/0x140
start_kernel_thread+0x14/0x18
While shutting down fabric controller, if nvme keep-alive request sneaks
in then it would be flushed off. The nvme_keep_alive_end_io function is
then invoked to handle the end of the keep-alive operation which
decrements the admin->q_usage_counter and assuming this is the last/only
request in the admin queue then the admin->q_usage_counter becomes zero.
If that happens then blk-mq destroy queue operation (blk_mq_destroy_
queue()) which could be potentially running simultaneously on another
cpu (as this is the controller shutdown code path) would forward
progress and deletes the admin queue. So, now from this point onward
we are not supposed to access the admin queue resources. However the
issue here's that the nvme keep-alive thread running hw/hctx queue
dispatch operation hasn't yet finished its work and so it could still
potentially access the admin queue resource while the admin queue had
been already deleted and that causes the above crash.
This fix helps avoid the observed crash by implementing keep-alive as a
synchronous operation so that we decrement admin->q_usage_counter only
after keep-alive command finished its execution and returns the command
status back up to its caller (blk_execute_rq()). This would ensure that
fabric shutdown code path doesn't destroy the fabric admin queue until
keep-alive request finished execution and also keep-alive thread is not
running hw/hctx queue dispatch operation.

nvme-loop: flush off pending I/O while shutting down loop controller
While shutting down loop controller, we first quiesce the admin/IO queue, delete the admin/IO tag-set and then at last destroy the admin/IO queue. However it's quite possible that during the window between quiescing and destroying of the admin/IO queue, some admin/IO request might sneak in and if that happens then we could potentially encounter a hung task because shutdown operation can't forward progress until any pending I/O is flushed off. This commit helps ensure that before destroying the admin/IO queue, we unquiesce the admin/IO queue so that any outstanding requests, which are added after the admin/IO queue is quiesced, are now flushed to its completion.

bpf: Fix print_reg_state's constant scalar dump
print_reg_state() should not consider adding reg->off to reg->var_off.value
when dumping scalars. Scalars can be produced with reg->off != 0 through
BPF_ADD_CONST, and thus as-is this can skew the register log dump.

bpf: Fix incorrect delta propagation between linked registers
Nathaniel reported a bug in the linked scalar delta tracking, which can lead
to accepting a program with OOB access. The specific code is related to the
sync_linked_regs() function and the BPF_ADD_CONST flag, which signifies a
constant offset between two scalar registers tracked by the same register id.
The verifier attempts to track "similar" scalars in order to propagate bounds
information learned about one scalar to others. For instance, if r1 and r2
are known to contain the same value, then upon encountering 'if (r1 != 0x1234)
goto xyz', not only does it know that r1 is equal to 0x1234 on the path where
that conditional jump is not taken, it also knows that r2 is.
Additionally, with env->bpf_capable set, the verifier will track scalars
which should be a constant delta apart (if r1 is known to be one greater than
r2, then if r1 is known to be equal to 0x1234, r2 must be equal to 0x1233.)
The code path for the latter in adjust_reg_min_max_vals() is reached when
processing both 32 and 64-bit addition operations. While adjust_reg_min_max_vals()
knows whether dst_reg was produced by a 32 or a 64-bit addition (based on the
alu32 bool), the only information saved in dst_reg is the id of the source
register (reg->id, or'ed by BPF_ADD_CONST) and the value of the constant
offset (reg->off).
Later, the function sync_linked_regs() will attempt to use this information
to propagate bounds information from one register (known_reg) to others,
meaning, for all R in linked_regs, it copies known_reg range (and possibly
adjusting delta) into R for the case of R->id == known_reg->id.
For the delta adjustment, meaning, matching reg->id with BPF_ADD_CONST, the
verifier adjusts the register as reg = known_reg; reg += delta where delta
is computed as (s32)reg->off - (s32)known_reg->off and placed as a scalar
into a fake_reg to then simulate the addition of reg += fake_reg. This is
only correct, however, if the value in reg was created by a 64-bit addition.
When reg contains the result of a 32-bit addition operation, its upper 32
bits will always be zero. sync_linked_regs() on the other hand, may cause
the verifier to believe that the addition between fake_reg and reg overflows
into those upper bits. For example, if reg was generated by adding the
constant 1 to known_reg using a 32-bit alu operation, then reg->off is 1
and known_reg->off is 0. If known_reg is known to be the constant 0xFFFFFFFF,
sync_linked_regs() will tell the verifier that reg is equal to the constant
0x100000000. This is incorrect as the actual value of reg will be 0, as the
32-bit addition will wrap around.
Example:
0: (b7) r0 = 0; R0_w=0
1: (18) r1 = 0x80000001; R1_w=0x80000001
3: (37) r1 /= 1; R1_w=scalar()
4: (bf) r2 = r1; R1_w=scalar(id=1) R2_w=scalar(id=1)
5: (bf) r4 = r1; R1_w=scalar(id=1) R4_w=scalar(id=1)
6: (04) w2 += 2147483647; R2_w=scalar(id=1+2147483647,smin=0,smax=umax=0xffffffff,var_off=(0x0; 0xffffffff))
7: (04) w4 += 0 ; R4_w=scalar(id=1+0,smin=0,smax=umax=0xffffffff,var_off=(0x0; 0xffffffff))
8: (15) if r2 == 0x0 goto pc+1
10: R0=0 R1=0xffffffff80000001 R2=0x7fffffff R4=0xffffffff80000001 R10=fp0
What can be seen here is that r1 is copied to r2 and r4, such that {r1,r2,r4}.id
are all the same which later lets sync_linked_regs() to be invoked. Then, in
a next step constants are added with alu32 to r2 and r4, setting their ->off,
as well as id |= BPF_ADD_CONST. Next, the conditional will bind r2 and
propagate ranges to its linked registers. The verifier now believes the upper
32 bits of r4 are r4=0xffffffff80000001, while actually r4=r1=0x80000001.
One approach for a simple fix suitable also for stable is to limit the constant
delta tracking to only 64-bit alu addition. If necessary at some later point,
BPF_ADD_CONST could be split into BPF_ADD_CONST64 and BPF_ADD_CONST32 to avoid
mixing the two under the tradeoff to further complicate sync_linked_regs().
However, none of the added tests from

maple_tree: correct tree corruption on spanning store
Patch series "maple_tree: correct tree corruption on spanning store", v3. There has been a nasty yet subtle maple tree corruption bug that appears to have been in existence since the inception of the algorithm. This bug seems far more likely to happen since commit |

riscv, bpf: Make BPF_CMPXCHG fully ordered
According to the prototype formal BPF memory consistency model
discussed e.g. in [1] and following the ordering properties of
the C/in-kernel macro atomic_cmpxchg(), a BPF atomic operation
with the BPF_CMPXCHG modifier is fully ordered. However, the
current RISC-V JIT lowerings fail to meet such memory ordering
property. This is illustrated by the following litmus test:
BPF BPF__MP+success_cmpxchg+fence
{
0:r1=x; 0:r3=y; 0:r5=1;
1:r2=y; 1:r4=f; 1:r7=x;
}
P0 | P1 ;
*(u64 *)(r1 + 0) = 1 | r1 = *(u64 *)(r2 + 0) ;
r2 = cmpxchg_64 (r3 + 0, r4, r5) | r3 = atomic_fetch_add((u64 *)(r4 + 0), r5) ;
| r6 = *(u64 *)(r7 + 0) ;
exists (1:r1=1 /\ 1:r6=0)
whose "exists" clause is not satisfiable according to the BPF
memory model. Using the current RISC-V JIT lowerings, the test
can be mapped to the following RISC-V litmus test:
RISCV RISCV__MP+success_cmpxchg+fence
{
0:x1=x; 0:x3=y; 0:x5=1;
1:x2=y; 1:x4=f; 1:x7=x;
}
P0 | P1 ;
sd x5, 0(x1) | ld x1, 0(x2) ;
L00: | amoadd.d.aqrl x3, x5, 0(x4) ;
lr.d x2, 0(x3) | ld x6, 0(x7) ;
bne x2, x4, L01 | ;
sc.d x6, x5, 0(x3) | ;
bne x6, x4, L00 | ;
fence rw, rw | ;
L01: | ;
exists (1:x1=1 /\ 1:x6=0)
where the two stores in P0 can be reordered. Update the RISC-V
JIT lowerings/implementation of BPF_CMPXCHG to emit an SC with
RELEASE ("rl") annotation in order to meet the expected memory
ordering guarantees. The resulting RISC-V JIT lowerings of
BPF_CMPXCHG match the RISC-V lowerings of the C atomic_cmpxchg().
Other lowerings were fixed via

io_uring/sqpoll: ensure task state is TASK_RUNNING when running task_work
When the sqpoll is exiting and cancels pending work items, it may need
to run task_work. If this happens from within io_uring_cancel_generic(),
then it may be under waiting for the io_uring_task waitqueue. This
results in the below splat from the scheduler, as the ring mutex may be
attempted grabbed while in a TASK_INTERRUPTIBLE state.
Ensure that the task state is set appropriately for that, just like what
is done for the other cases in io_run_task_work().
do not call blocking ops when !TASK_RUNNING; state=1 set at [<0000000029387fd2>] prepare_to_wait+0x88/0x2fc

afs: Fix lock recursion
afs_wake_up_async_call() can incur lock recursion. The problem is that it is called from AF_RXRPC whilst holding the ->notify_lock, but it tries to take a ref on the afs_call struct in order to pass it to a work queue - but if the afs_call is already queued, we then have an extraneous ref that must be put... calling afs_put_call() may call back down into AF_RXRPC through rxrpc_kernel_shutdown_call(), however, which might try taking the ->notify_lock again. This case isn't very common, however, so defer it to a workqueue. The oops looks something like: BUG: spinlock recursion on CPU#0, krxrpcio/7001/1646 lock: 0xffff888141399b30, .magic: dead4ead, .owner: krxrpcio/7001/1646, .owner_cpu: 0 CPU: 0 UID: 0 PID: 1646 Comm: krxrpcio/7001 Not tainted 6.12.0-rc2-build3+ #4351 Hardware name: ASUS All Series/H97-PLUS, BIOS 2306 10/09/2014 Call Trace: <TASK> dump_stack_lvl+0x47/0x70 do_raw_spin_lock+0x3c/0x90 rxrpc_kernel_shutdown_call+0x83/0xb0 afs_put_call+0xd7/0x180 rxrpc_notify_socket+0xa0/0x190 rxrpc_input_split_jumbo+0x198/0x1d0 rxrpc_input_data+0x14b/0x1e0 ? rxrpc_input_call_packet+0xc2/0x1f0 rxrpc_input_call_event+0xad/0x6b0 rxrpc_input_packet_on_conn+0x1e1/0x210 rxrpc_input_packet+0x3f2/0x4d0 rxrpc_io_thread+0x243/0x410 ? __pfx_rxrpc_io_thread+0x10/0x10 kthread+0xcf/0xe0 ? __pfx_kthread+0x10/0x10 ret_from_fork+0x24/0x40 ? __pfx_kthread+0x10/0x10 ret_from_fork_asm+0x1a/0x30 </TASK> Signed-off-by: David Howells <dhowells@redhat.com> Link: https://lore.kernel.org/r/1394602.1729162732@warthog.procyon.org.uk cc: Marc Dionne <marc.dionne@auristor.com> cc: linux-afs@lists.infradead.org cc: linux-fsdevel@vger.kernel.org Signed-off-by: Christian Brauner <brauner@kernel.org> |
