It appears that some vendors provision the boot areas with valid part
tables (GPT) in order to have identifiable partitions for device and
firmware specific data, such has the qualcomm CDT (Qualcomm Config
Data Table). Additionally, these boot areas can be utilized to host
device-specific IDs, calibration data, and other critical information.

For SOCK_STREAM sockets, if user buffer size (len) is less
than skb size (skb->len), the remaining data from skb
will be lost after calling kfree_skb().
To fix this, move the statement for partial reading
above skb deletion.

====================
ovpn: pull request for net-next: ovpn 2025-05-15
this is a new version of the previous pull request.
These time I have removed the fixes that we are still discussing,
so that we don't hold the entire series back.
There is a new fix though: it's about properly checking the return value
of skb_to_sgvec_nomark(). I spotted the issue while testing pings larger
than the iface's MTU on a TCP VPN connection.
I have added various Closes and Link tags where applicable, so
that we have references to GitHub tickets and other public discussions.
Since I have resent the PR, I have also added Andrew's Reviewed-by to
the first patch.
Please pull or let me know if something should be changed!

The maximum DMA transfer size is limited by the maximum values that can
be written to the word count fields (WDLENx) in the Transmit and Control
Data Registers (SITDR2/SIRDR2). As all MSIOF variants support
transferring data of multiple (two or four) groups, the maximum size can
be doubled by using two groups instead of one, thus reducing setup
overhead for very large SPI transfers.

The maximum amount of data to transfer in a single DMA request is
calculated from the FIFO sizes (which is technically not 100% correct,
but a simplification, as it is limited by the maximum word count values
in the Transmit and Control Data Registers). However, in case there is
both data to transmit and to receive, the transmit limit is overwritten
by the receive limit.
Fix this by using the minimum applicable FIFO size instead. Move the
calculation outside the loop, so it is not repeated for each individual
DMA transfer.
As currently tx_fifo_size is always equal to rx_fifo_size, this bug had
no real impact.

The Clock-Synchronized Serial Interfaces with FIFO (MSIOF) driver
matches against both SoC-specific and family-specific compatible values
to maintain backwards-compatibility with old DTBs predating the
introduction of the family-specific compatible values.
For RZ/G1, the SoC-specific compatible match entry can be removed from
the driver: their DT always had the family-specific compatible values,
and thus there was never a need to add the SoC-specific compatible
values to the driver.
For R-Car Gen2 and M3-W, the SoC-specific compatible match entries can
be removed, too, as there are a few points in time where DT
backwards-compatibility was broken for other reasons:
- Legacy DT clock support is no longer supported since commit
58256143cff7c2e0 ("clk: renesas: Remove R-Car Gen2 legacy DT clock
support") in v5.5, and the addition of "renesas,rcar-gen2-msiof" to
DTS in v4.11 predates the completion of the clock conversion in
v4.15,
- Legacy DT LVDS support is no longer supported since commit
841281fe52a769fe ("drm: rcar-du: Drop LVDS device tree backward
compatibility") in v5.18, and the addition of
"renesas,rcar-gen3-msiof" in commit 8b51f97138ca22b6 ("arm64: dts:
r8a7796: Use R-Car Gen 3 fallback binding for msiof nodes") in v4.11
predates the LVDS conversion in commit 58e8ed2ee9abe718 ("arm64:
dts: renesas: Convert to new LVDS DT bindings") in v4.20.
For R-Car H3, the SoC-specific compatible match entry cannot be removed,
as its purpose is to handle an SoC-specific quirk.

'struct spmi_voltage_range' are only modified at runtime to compile a

So, simplify spmi_calculate_num_voltages() and compute n_voltages at

Constifying these structures moves some data to a read-only section, so

the same time. The shash algorithm will have the driver name
"hmac-shash(XXX-driver)". Due to a quirk in the API, there is no way
to locate the shash algorithm using the name "hmac(XXX-driver)". It
has to be addressed as either "hmac(XXX)" or "hmac-shash(XXX-driver)".
Looking it up with "hmac(XXX-driver)" will simply trigger the creation
of another instance, and on the second instantiation this will fail
with EEXIST.
Catch the error EEXIST along with ENOENT since it is expected.
If a real shash algorithm came this way, it would be addressed using
the proper name "hmac-shash(XXX-driver)".

Add support to crypto_inst_setname for having a driver template
name that differs from the algorithm template name.

Add export_import and import_core so that hmac can be used as a
fallback by block-only drivers.
