A common pattern when using xdp_redirect_map() is to create a device map
where the lookup key is simply ifindex. Because device maps are arrays,
this leaves holes in the map, and the map has to be sized to fit the
largest ifindex, regardless of how many devices actually are actually
needed in the map.
This patch adds a second type of device map where the key is looked up
using a hashmap, instead of being used as an array index. This allows maps
to be densely packed, so they can be smaller.

When we changed the device and CPU maps to use linked lists instead of
bitmaps, we also removed the need for the map_insert_ctx() helpers to keep
track of the bitmaps inside each map. However, it seems I forgot to remove
the function definitions stubs, so remove those here.

Since commit ebc278f15759 ("ARM: mvebu: remove static LED setup for
netxbig boards"), no one in upstream passes in the platform data to
this driver.
Squash leds-kirkwood-netxbig.h into the driver, and remove the legacy
board-file support.

With all the pieces in place, we can finally propagate the
iommu_iotlb_gather structure from the call to unmap() down to the IOMMU
drivers' implementation of ->tlb_add_page(). Currently everybody ignores
it, but the machinery is now there to defer invalidation.

The ->tlb_add_flush() callback in the io-pgtable API now looks a bit
silly:
- It takes a size and a granule, which are always the same
- It takes a 'bool leaf', which is always true
- It only ever flushes a single page
With that in mind, replace it with an optional ->tlb_add_page() callback
that drops the useless parameters.
Signed-off-by: Will Deacon <will@kernel.org>

Now that all IOMMU drivers using the io-pgtable API implement the
->tlb_flush_walk() and ->tlb_flush_leaf() callbacks, we can use them in
the io-pgtable code instead of ->tlb_add_flush() immediately followed by
->tlb_sync().
Signed-off-by: Will Deacon <will@kernel.org>
|

In preparation for deferring TLB flushes to iommu_tlb_sync(), introduce
two new synchronous invalidation helpers to the io-pgtable API, which
allow the unmap() code to force invalidation in cases where it cannot be
deferred (e.g. when replacing a table with a block or when TLBI_ON_MAP
is set).
Signed-off-by: Will Deacon <will@kernel.org>
|
|
To allow IOMMU drivers to batch up TLB flushing operations and postpone
them until ->iotlb_sync() is called, extend the prototypes for the
->unmap() and ->iotlb_sync() IOMMU ops callbacks to take a pointer to
the current iommu_iotlb_gather structure.
All affected IOMMU drivers are updated, but there should be no
functional change since the extra parameter is ignored for now.

HE allows peers to negotiate the aggregation fragmentation level to be used
during transmission. The level can be 1-3. The Ext element is added behind
the ADDBA request inside the action frame. The responder will then reply
with the same level or a lower one if the requested one is not supported.
This patch only handles the negotiation part as the ADDBA frames get passed
to the ATH11k firmware, which does the rest of the magic for us aswell as
generating the requests.

Add functions that verify data pages that have been read from a
fs-verity file, against that file's Merkle tree. These will be called
from filesystems' ->readpage() and ->readpages() methods.
Since data verification can block, a workqueue is provided for these
methods to enqueue verification work from their bio completion callback.
See the "Verifying data" section of
Documentation/filesystems/fsverity.rst for more information.

Add the fsverity_file_open() function, which prepares an fs-verity file
to be read from. If not already done, it loads the fs-verity descriptor
from the filesystem and sets up an fsverity_info structure for the inode
which describes the Merkle tree and contains the file measurement. It
also denies all attempts to open verity files for writing.
This commit also begins the include/linux/fsverity.h header, which
declares the interface between fs/verity/ and filesystems.

Analogous to fs/crypto/, add fields to the VFS inode and superblock for
use by the fs/verity/ support layer:
- ->s_vop: points to the fsverity_operations if the filesystem supports
fs-verity, otherwise is NULL.
- ->i_verity_info: points to cached fs-verity information for the inode
after someone opens it, otherwise is NULL.
- S_VERITY: bit in ->i_flags that identifies verity inodes, even when
they haven't been opened yet and thus still have NULL ->i_verity_info.

If gpiolib is disabled, we use the inline stubs from gpio/consumer.h
instead of regular definitions of GPIO API. The stubs for 'optional'
variants of gpiod_get routines return NULL in this case as if the
relevant GPIO wasn't found. This is correct so far.
Calling other (non-gpio_get) stubs from this header triggers a warning
because the GPIO descriptor couldn't have been requested. The warning
however is unconditional (WARN_ON(1)) and is emitted even if the passed
descriptor pointer is NULL.
We don't want to force the users of 'optional' gpio_get to check the
returned pointer before calling e.g. gpiod_set_value() so let's only
WARN on non-NULL descriptors.

The Tegra EQOS driver already resets the MDIO bus at probe time via the
reset GPIO specified in the phy-reset-gpios device tree property. There
is no need to reset the bus again later on.
This avoids the need to query the device tree for the snps,reset GPIO,
which is not part of the Tegra EQOS device tree bindings. This quiesces
an error message from the generic bus reset code if it doesn't find the
snps,reset related delays.

The function padata_reorder will use a timer when it cannot progress
while completed jobs are outstanding (pd->reorder_objects > 0). This
is suboptimal as if we do end up using the timer then it would have
introduced a gratuitous delay of one second.
In fact we can easily distinguish between whether completed jobs
are outstanding and whether we can make progress. All we have to
do is look at the next pqueue list.
This patch does that by replacing pd->processed with pd->cpu so
that the next pqueue is more accessible.
A work queue is used instead of the original try_again to avoid
hogging the CPU.
Note that we don't bother removing the work queue in
padata_flush_queues because the whole premise is broken. You
cannot flush async crypto requests so it makes no sense to even
try. A subsequent patch will fix it by replacing it with a ref
counting scheme.

The udp_ip4_ind bit is set only for IPv4 UDP non-fragmented packets
so that the hardware can flip the checksum to 0xFFFF if the computed
checksum is 0 per RFC768.
However, this bit had to be set for IPv6 UDP non fragmented packets
as well per hardware requirements. Otherwise, IPv6 UDP packets
with computed checksum as 0 were transmitted by hardware and were
dropped in the network.
In addition to setting this bit for IPv6 UDP, the field is also
appropriately renamed to udp_ind as part of this change.

virtual devices weren't shared with the callers of
dev_pm_opp_attach_genpd() earlier.
But the IO device drivers would want to do that. This patch updates the
prototype of dev_pm_opp_attach_genpd() to accept another argument to
return the pointer to the array of genpd virtual devices.

Crypto test failures in FIPS mode cause an immediate panic, but
on some system the cryptographic boundary extends beyond just
the Linux controlled domain.
Add a simple atomic notification chain to allow interested parties
to register to receive notification prior to us kicking the bucket.

C flow dissector supports input flags that tell it to customize parsing
by either stopping early or trying to parse as deep as possible. Pass
those flags to the BPF flow dissector so it can make the same
decisions. In the next commits I'll add support for those flags to
our reference bpf_flow.c
v3:
* Export copy of flow dissector flags instead of moving (Alexei Starovoitov)
