virtio_crypto_dataq_akcipher_callback() sets the result length from the
device-reported response length without bounding it to the destination
buffer, which was allocated for the original request length.
sg_copy_from_buffer() then reads that many bytes from the destination
buffer; a backend reporting a larger length over-reads adjacent kernel
heap into the caller's scatterlist (an out-of-bounds read).
Clamp the reported length to the originally requested destination length.
A conforming device reports no more than that, so valid results are
unaffected.

Pull kthread vfs updates from Christian Brauner:
"This stops kernel threads from sharing filesystem state with
userspace. This work is about 3 cycles old and has been in -next
for about that time.
When the kernel boots init_task creates PID 1 and then kthreadd. From
that point every kthread and PID 1 share the same fs_struct. That is
why pivot_root() has to rewrite the fs_struct of all kthreads. The
rewriting exists so that kthreads can use init's filesystem state when
they want to. It also means userspace can move the ground out from
under the kernel.
PID 1 now gets a completely separate fs_struct. All kthreads are
anchored in a private SB_KERNMOUNT instance of nullfs that cannot be
mounted on and cannot be used to follow other mounts. Userspace init
can no longer affect kthread filesystem state and kthreads can no
longer affect userspace fs state without explicit opting in to that.
Path lookup from a kthread now fails by default. It makes it
deliberately hard to offload security sensitive operations into init's
filesystem state from a kthread.
Places that legitimately need to look something up there opt in
through the new scoped_with_init_fs() which temporarily overrides the
caller's fs_struct with init's. usermodehelpers remain the only kernel
tasks that genuinely share init's filesystem state, since they execute
random binaries in the root filesystem (excellent...).
The visible result is that /proc/2/root is a nullfs with an empty
mountinfo while /proc/1/root is the real root"

Use crypto_memneq() for a constant-time comparison.
sa_aead_dma_in_callback() compares the computed authentication tag
against the received tag with memcmp(), which short-circuits on the
first differing byte. An attacker who can submit decrypt requests and
observe completion latency could recover the expected tag byte by byte.
Valid tag forgery for AEAD breaks the INT-CTXT guarantee.

The AAD buffer allocated in qce_aead_ccm_prepare_buf_assoclen()
can be smaller than the length later programmed into the DMA
scatterlist.
The allocation size is currently calculated as:
ALIGN(assoclen, 16) + MAX_CCM_ADATA_HEADER_LEN
while the DMA length is set to:
ALIGN(assoclen + adata_header_len, 16)
Since ALIGN() does not distribute over addition, the allocation
can be smaller than the DMA length. For example, when
assoclen = 32 and adata_header_len = 2:
allocation = ALIGN(32, 16) + 6 = 38
DMA length = ALIGN(32 + 2, 16) = 48
As a result, the QCE hardware can read beyond the allocated
buffer while computing the CBC-MAC over the associated data.
The extra bytes are folded into the authentication tag,
resulting in an incorrect tag and causing CCM self-test
failures such as:
alg: aead: ccm-aes-qce encryption test failed (wrong result)
on test vector 8
Fix the allocation by adding the maximum possible AAD header
length before alignment:
ALIGN(assoclen + MAX_CCM_ADATA_HEADER_LEN, 16)
This guarantees that the allocated buffer is large enough
for the fully padded AAD data for all supported header sizes.

On a hardware analytics error, decompress retries through the software
fallback, which writes req->dst with the CPU while it is still mapped
DMA_FROM_DEVICE. With SWIOTLB active the later dma_unmap_sg() copies the
stale bounce buffer over req->dst, corrupting the result.
Unmap before the fallback runs. The async path unmaps inline; the sync
path signals the retry with -EAGAIN so iaa_comp_adecompress() runs the
fallback after unmapping.

Since commit e2c3b6b21c77 ("mm: zswap: use SG list decompression APIs
from zsmalloc"), zswap passes the raw zsmalloc SG list directly to
crypto drivers, so a compressed object spanning multiple pages reaches
IAA as a multi-entry source. Such requests currently fall back to
software decompression.
As IAA hardware requires a single DMA source buffer, linearize small
multi-entry sources into a pre-allocated bounce page and submit that to
the hardware instead of falling back to software. Keep the software
fallback only for multi-entry destinations. This recovers most of the
performance lost by using the software fallback.
Store the bounce-page state in the acomp request context alongside the
existing compression CRC, free it through a shared source-unmap helper,
and back the pages with a small module-wide mempool so the path remains
available in reclaim-driven callers.

IAA cannot process source or destination scatterlists with more than one
entry directly. Instead of failing these requests, route them through a
separate deflate acomp transform and keep the request alive in software.
The IAA driver has never handled multi-entry scatterlists, but the
limitation was latent until commit e2c3b6b21c77 ("mm: zswap: use SG list
decompression APIs from zsmalloc") made zswap pass the raw zsmalloc SG
list directly to crypto drivers, so objects spanning multiple pages now
reach IAA as multi-entry sources and would otherwise fail decompression.
Fallback to the generic DEFLATE implementation for scatterlists with
more than one entry. After the multi-entry cases fall back early,
simplify the DMA mapping path to a single scatterlist entry and fall
back on mapping failure as well.
Add counters to track the number of requests processed by the software
implementation on the compression direction.

In the CCM B0 block the message-length field Q spans L bytes, where
L (cl in the driver) is derived from the cipher IV flags byte as
c_ivin[0] + 1. set_aead_auth_iv() hardcoded writing only the last 2
bytes of a_ivin with cryptlen, implicitly assuming cl = 2.
When cl = 3 (a shorter nonce yielding a 3-byte length field) and the
packet is longer than 65535 bytes, cryptlen no longer fits in 2 bytes.
The dropped high byte made the auth IV built by the driver differ from
the one consumed by the hardware, so the software/hardware comparison
failed and the CCM request errored out.
Write the last cl bytes of a_ivin in a loop driven by the IV's CL
value, so the length-field width always matches the algorithm
configuration instead of assuming a fixed 2-byte field.

Convert the interrupt acquisition from irq_of_parse_and_map() to
platform_get_irq(), which resolves the IRQ from the device's interrupts
property via of_irq_get(). Flip the error check from testing for zero to
testing for a negative errno, and drop the now-unused
caam_jr_irq_dispose_mapping() callback and its devm_add_action_or_reset()
cleanup, since platform_get_irq() manages the mapping internally.
Replace the open-coded platform_get_resource() plus devm_ioremap()
sequence with devm_platform_ioremap_resource(), which fetches the
resource, requests the region and maps it in one call.
Each fsl,sec-*-job-ring node has a distinct 0x10000 reg region and
interrupts property, so the region reservation added by
devm_ioremap_resource() is exclusive and does not introduce overlap
failures.

The driver uses devm_request_irq() for the IRQ, but cleans up the
tasklet and DMA rings inside the remove function. Since devres frees
the IRQ only after the remove function returns, a window exists where a
pending hardware interrupt can reschedule the tasklet after it has been
killed, leading to use-after-free of the descriptor rings.
Fix by switching to plain request_irq() and adding the corresponding
free_irq() calls in the remove function and the probe error path before
tasklet_kill(), ensuring the IRQ is fully torn down before the tasklet
is killed.
Rename goto error path to err_tasklet as that's more descriptive.

The Qualcomm Crypto Engine (QCE) driver currently lacks support for
runtime power management (PM) and interconnect bandwidth control.
As a result, the hardware remains fully powered and clocks stay
enabled even when the device is idle. Additionally, static
interconnect bandwidth votes are held indefinitely, preventing the
system from reclaiming unused bandwidth.
Address this by enabling runtime PM and dynamic interconnect
bandwidth scaling to allow the system to suspend the device when idle
and scale interconnect usage based on actual demand. Improve overall
system efficiency by reducing power usage and optimizing interconnect
resource allocation.

dma_map_resource() and gen_pool_dma_alloc() have no devm helpers, so the
mapping is released by hand. This is error-prone: the error path iterates
over every engine and can dma_unmap_resource() an uninitialized/zero
address for engines that were never set up.
Convert the teardown into a devm_add_action_or_reset() callback registered
only after a mapping is successfully established. The callback fires
automatically on probe failure (devres rollback) and on device detach,
after mv_cesa_remove() has already stopped the engine and freed the IRQ,
so the unmap still happens in a safe order. This deletes the explicit
mv_cesa_put_sram() calls and the uninitialized-engine bug at once.
Add a struct mv_cesa_dev back-pointer to struct mv_cesa_engine so the
callback can reach cesa->dev and cesa->sram_size from the engine alone.

Using sg_dma_len() is only valid after mapping a scatterlist with
dma_map_sg(). However, starfive_aes_aead_do_one_req() uses it before
mapping the scatterlist.
Use the original scatterlist length because the DMA length has not been
populated yet when CONFIG_NEED_SG_DMA_LENGTH=y.

If ops->register_algs() fails, the error path repeatedly calls the same
ops->unregister_algs() from the failed registration. Use the loop index
to unregister the previously registered algorithms instead.

Perform rctx->cryptlen calculation in tegra_gcm_do_one_req() the same way
it is done in tegra_ccm_crypt_init(). The current formulae may lead to a
crash if a caller does not call tegra_gcm_setauthsize() and so ctx->authsize
remains zero. Then a decrypt operation with incorrect rctx->cryptlen will
lead to a write beyound rctx->dst_sg buffer.
As a follow-up cleanup delete struct tegra_aead_ctx->authsize field since
it appears to be completely unused. Also simplify tegra_ccm_setauthsize()
and tegra_gcm_setauthsize() functions respectively.

sec_create_qp_ctx() reads ctx->type_supported to pick its callback, but
sec_skcipher_init() and sec_aead_init() set it after sec_ctx_base_init()
has already walked the qp_ctx loop, so the value is uninitialized when
first consumed. Set type_supported in sec_ctx_base_init() before the
loop; the alg init paths now just select req_op from it.
