9 months agoftruncate: pass a signed offset
Arnd Bergmann [Wed, 19 Jun 2024 09:34:09 +0000 (11:34 +0200)]
ftruncate: pass a signed offset

The old ftruncate() syscall, using the 32-bit off_t misses a sign
extension when called in compat mode on 64-bit architectures.  As a
result, passing a negative length accidentally succeeds in truncating
to file size between 2GiB and 4GiB.

Changing the type of the compat syscall to the signed compat_off_t
changes the behavior so it instead returns -EINVAL.

The native entry point, the truncate() syscall and the corresponding
loff_t based variants are all correct already and do not suffer
from this mistake.

or return a null state.

In commit 42a2f6664e18 ("staging: vc04_services: Move global g_state to
vchiq_state") the global state was moved to the vchiq_mgnt structures

helpers and instead replaced users of this helper with the assumption
that the state is always available and the remote connected.

The conversion does ensure that the state is always available, so some
remaining state null pointer checks that remain are unnecessary, but the
assumption that the remote is present and initialised is incorrect.

Fix this broken assumption by re-introducing the logic that was lost

by accident as the remaining COMP_EMPTY() platform entry became the codec
entry, and the platform entry became completely empty, effectively the
same as COMP_DUMMY() since snd_soc_fill_dummy_dai() doesn't do anything
for platform entries.

This causes a KASAN out-of-bounds warning in mtk_soundcard_common_probe()

  2. rhashtable_init() fails when some fields of rhashtable_params

The second case cannot happen since there is a static const rhashtable_params

problem with memory allocation.

Thus, there is no sense in using WARN() to handle this error and it can be
safely removed.

The 1st bug is the way may_goto is patched. When offset is negative
it should be patched differently.
The 2nd bug is in the verifier:
when current state may_goto_depth is equal to visited state may_goto_depth
it means there is an actual infinite loop. It's not correct to prune
exploration of the program at this point.
Note, that this check doesn't limit the program to only one may_goto insn,
since 2nd and any further may_goto will increment may_goto_depth only
in the queued state pushed for future exploration. The current state
will have may_goto_depth == 0 regardless of number of may_goto insns

In the past, there were similar failures reported by CI from other IGT
tests, observed on other platforms.

Before commit 63baf4f3d587 ("drm/i915/gt: Only wait for GPU activity
before unbinding a GGTT fence"), i915_vma_revoke_fence() was waiting for
idleness of vma->active via fence_update().   That commit introduced
vma->fence->active in order for the fence_update() to be able to wait
selectively on that one instead of vma->active since only idleness of
fence registers was needed.  But then, another commit 0d86ee35097a
("drm/i915/gt: Make fence revocation unequivocal") replaced the call to
fence_update() in i915_vma_revoke_fence() with only fence_write(), and
also added that GEM_BUG_ON(!i915_active_is_idle(&fence->active)) in front.
No justification was provided on why we might then expect idleness of
vma->fence->active without first waiting on it.

The issue can be potentially caused by a race among revocation of fence
registers on one side and sequential execution of signal callbacks invoked
on completion of a request that was using them on the other, still
processed in parallel to revocation of those fence registers.  Fix it by
waiting for idleness of vma->fence->active in i915_vma_revoke_fence().

causes interrupts to be lost because they are not configured in the
corresponding core.

Use the core index to access the correct ISR instead of a hardcoded 0.

Huacai Chen [Sun, 23 Jun 2024 03:41:13 +0000 (11:41 +0800)]
irqchip/loongson-eiointc: Use early_cpu_to_node() instead of cpu_to_node()

Multi-bridge machines required that all eiointc controllers in the system
are initialized, otherwise the system does not boot.

The initialization happens on the boot CPU during early boot and relies on
cpu_to_node() for identifying the individual nodes.

That works when the number of possible CPUs is large enough, but with a
command line limit, e.g. "nr_cpus=$N" for kdump, but fails when the CPUs
of the secondary nodes are not covered.

During early ACPI enumeration all CPU to node mappings are recorded up to
CONFIG_NR_CPUS. These are accessible via early_cpu_to_node() even in the
case that "nr_cpus=N" truncates the number of possible CPUs and only
provides the possible CPUs via cpu_to_node() translation.

Change the node lookup in the driver to use early_cpu_to_node() so that
even with a limitation on the number of possible CPUs all eointc instances
are initialized.

This can't obviously cure the case where CONFIG_NR_CPUS is too small.

pwm: stm32: Fix calculation of prescaler

A small prescaler is beneficial, as this improves the resolution of the
duty_cycle configuration. However if the prescaler is too small, the
maximal possible period becomes considerably smaller than the requested
value.

One situation where this goes wrong is the following: With a parent
clock rate of 208877930 Hz and max_arr = 0xffff = 65535, a request for
period = 941243 ns currently results in PSC = 1. The value for ARR is
then calculated to

ARR = 941243 * 208877930 / (1000000000 * 2) - 1 = 98301

This value is bigger than 65535 however and so doesn't fit into the
respective register field. In this particular case the PWM was
configured for a period of 313733.4806027616 ns (with ARR = 98301 &
0xffff). Even if ARR was configured to its maximal value, only period =
627495.6861167669 ns would be achievable.

Fix the calculation accordingly and adapt the comment to match the new
algorithm.

With the calculation fixed the above case results in PSC = 2 and so an
actual period of 941229.1667195285 ns.

ibmvnic: Free any outstanding tx skbs during scrq reset

There are 2 types of outstanding tx skb's:
Type 1: Packets that are sitting in the drivers ind_buff that are
waiting to be batch sent to the NIC. During a device reset, these are
freed with a call to ibmvnic_tx_scrq_clean_buffer()
Type 2: Packets that have been sent to the NIC and are awaiting a TX
completion IRQ. These are free'd during a reset with a call to
clean_tx_pools()

During any reset which requires us to free the tx irq, ensure that the
Type 2 skb references are freed. Since the irq is released, it is
impossible for the NIC to inform of any completions.

Furthermore, later in the reset process is a call to init_tx_pools()
which marks every entry in the tx pool as free (ie not outstanding).
So if the driver is to make a call to init_tx_pools(), it must first
be sure that the tx pool is empty of skb references.

This issue was discovered by observing the following in the logs during
EEH testing:
TX free map points to untracked skb (tso_pool 0 idx=4)
TX free map points to untracked skb (tso_pool 0 idx=5)
TX free map points to untracked skb (tso_pool 1 idx=36)

The first patch is by Oleksij Rempel, it enhances the error handling
for tightly received RTS message in the j1939 protocol.

Shigeru Yoshida's patch fixes a kernel information leak in
j1939_send_one() in the j1939 protocol.

Followed by a patch by Oleksij Rempel for the j1939 protocol, to
properly recover from a CAN bus error during BAM transmission.

A patch by Chen Ni properly propagates errors in the kvaser_usb

9 months agobpf: Fix overrunning reservations in ringbuf
Daniel Borkmann [Fri, 21 Jun 2024 14:08:27 +0000 (16:08 +0200)]
bpf: Fix overrunning reservations in ringbuf

The BPF ring buffer internally is implemented as a power-of-2 sized circular
buffer, with two logical and ever-increasing counters: consumer_pos is the
consumer counter to show which logical position the consumer consumed the
data, and producer_pos which is the producer counter denoting the amount of
data reserved by all producers.

Each time a record is reserved, the producer that "owns" the record will
successfully advance producer counter. In user space each time a record is
read, the consumer of the data advanced the consumer counter once it finished
processing. Both counters are stored in separate pages so that from user
space, the producer counter is read-only and the consumer counter is read-write.

One aspect that simplifies and thus speeds up the implementation of both
producers and consumers is how the data area is mapped twice contiguously
back-to-back in the virtual memory, allowing to not take any special measures
for samples that have to wrap around at the end of the circular buffer data
area, because the next page after the last data page would be first data page
again, and thus the sample will still appear completely contiguous in virtual
memory.

Each record has a struct bpf_ringbuf_hdr { u32 len; u32 pg_off; } header for
book-keeping the length and offset, and is inaccessible to the BPF program.
Helpers like bpf_ringbuf_reserve() return `(void *)hdr + BPF_RINGBUF_HDR_SZ`
for the BPF program to use. Bing-Jhong and Muhammad reported that it is however
possible to make a second allocated memory chunk overlapping with the first
chunk and as a result, the BPF program is now able to edit first chunk's
header.

For example, consider the creation of a BPF_MAP_TYPE_RINGBUF map with size
of 0x4000. Next, the consumer_pos is modified to 0x3000 /before/ a call to
bpf_ringbuf_reserve() is made. This will allocate a chunk A, which is in
[0x0,0x3008], and the BPF program is able to edit [0x8,0x3008]. Now, lets
allocate a chunk B with size 0x3000. This will succeed because consumer_pos
was edited ahead of time to pass the `new_prod_pos - cons_pos > rb->mask`
check. Chunk B will be in range [0x3008,0x6010], and the BPF program is able
to edit [0x3010,0x6010]. Due to the ring buffer memory layout mentioned
earlier, the ranges [0x0,0x4000] and [0x4000,0x8000] point to the same data
pages. This means that chunk B at [0x4000,0x4008] is chunk A's header.
bpf_ringbuf_submit() / bpf_ringbuf_discard() use the header's pg_off to then
locate the bpf_ringbuf itself via bpf_ringbuf_restore_from_rec(). Once chunk
B modified chunk A's header, then bpf_ringbuf_commit() refers to the wrong
page and could cause a crash.

Fix it by calculating the oldest pending_pos and check whether the range
from the oldest outstanding record to the newest would span beyond the ring
buffer size. If that is the case, then reject the request. We've tested with
the ring buffer benchmark in BPF selftests (./benchs/run_bench_ringbufs.sh)
before/after the fix and while it seems a bit slower on some benchmarks, it
is still not significantly enough to matter.

Alexei Starovoitov [Wed, 19 Jun 2024 01:18:58 +0000 (18:18 -0700)]
bpf: Fix the corner case with may_goto and jump to the 1st insn.

When the following program is processed by the verifier:
L1: may_goto L2
    goto L1
L2: w0 = 0
    exit

the may_goto insn is first converted to:
L1: r11 = *(u64 *)(r10 -8)
    if r11 == 0x0 goto L2
    r11 -= 1
    *(u64 *)(r10 -8) = r11
    goto L1
L2: w0 = 0
    exit

then later as the last step the verifier inserts:
  *(u64 *)(r10 -8) = BPF_MAX_LOOPS
as the first insn of the program to initialize loop count.

When the first insn happens to be a branch target of some jmp the
bpf_patch_insn_data() logic will produce:
L1: *(u64 *)(r10 -8) = BPF_MAX_LOOPS
    r11 = *(u64 *)(r10 -8)
    if r11 == 0x0 goto L2
    r11 -= 1
    *(u64 *)(r10 -8) = r11
    goto L1
L2: w0 = 0
    exit

because instruction patching adjusts all jmps and calls, but for this
particular corner case it's incorrect and the L1 label should be one
instruction down, like:
    *(u64 *)(r10 -8) = BPF_MAX_LOOPS
L1: r11 = *(u64 *)(r10 -8)
    if r11 == 0x0 goto L2
    r11 -= 1
    *(u64 *)(r10 -8) = r11
    goto L1
L2: w0 = 0
    exit

and that's what this patch is fixing.
After bpf_patch_insn_data() call adjust_jmp_off() to adjust all jmps
that point to newly insert BPF_ST insn to point to insn after.

Note that bpf_patch_insn_data() cannot easily be changed to accommodate
this logic, since jumps that point before or after a sequence of patched
instructions have to be adjusted with the full length of the patch.

Conceptually it's somewhat similar to "insert" of instructions between other
instructions with weird semantics. Like "insert" before 1st insn would require
adjustment of CALL insns to point to newly inserted 1st insn, but not an
adjustment JMP insns that point to 1st, yet still adjusting JMP insns that
cross over 1st insn (point to insn before or insn after), hence use simple
adjust_jmp_off() logic to fix this corner case. Ideally bpf_patch_insn_data()
would have an auxiliary info to say where 'the start of newly inserted patch
is', but it would be too complex for backport.

Pull thermal control fixes from Rafael Wysocki:
 "These fix the Mediatek lvts_thermal driver, the Intel int340x driver,
  and the thermal core (two issues related to system suspend).

  Specifics:

   - Remove the filtered mode for mt8188 from lvts_thermal as it is not
     supported on this platform and fail the lvts_thermal initialization
     when the golden temperature is zero as that means the efuse data is
     not correctly set (Julien Panis)

   - Update the processor_thermal part of the Intel int340x driver to
     support shared interrupts as the processor thermal device interrupt
     may in fact be shared with PCI devices (Srinivas Pandruvada)

   - Synchronize the suspend-prepare and post-suspend actions of the
     thermal PM notifier to avoid a destructive race condition and
     change the priority of that notifier to the minimum to avoid
     interference between the work items spawned by it and the other
     PM notifiers during system resume (Rafael Wysocki)"
