If we only have assocdata with an omap-aes-gcm, it currently just

Current buffer handling logic fails in a case where the buffer contains
existing data from previous update which is divisible by block size.
This results in a block size of data to be left missing from the sg
list going out to the hw accelerator, ending up in stalling the
crypto accelerator driver (the last request never completes fully due
to missing data.)
Fix this by passing the total size of the data instead of the data size
of current request, and also parsing the buffer contents within the
prepare request handling.

The FW_ETH_TX_EO_WR used for sending UDP Segmentation Offload (USO)
requests expects the headers to be part of the descriptor and the
payload to be part of the SGL containing the DMA mapped addresses.
Hence, the DMA address in the first entry of the SGL can start after
the packet headers. Currently, unmap_sgl() tries to unmap from this
wrong offset, instead of the originally mapped DMA address.
So, use existing unmap_skb() instead, which takes originally saved DMA
addresses as input. Update all necessary Tx paths to save the original
DMA addresses, so that unmap_skb() can unmap them properly.
v2:
- No change.

In the vmx crypto Makefile we assign to a variable called TARGET and
pass that to the aesp8-ppc.pl and ghashp8-ppc.pl scripts.
The variable is meant to describe what flavour of powerpc we're
building for, eg. either 32 or 64-bit, and big or little endian.
Unfortunately TARGET is a fairly common name for a make variable, and
if it happens that TARGET is specified as a command line parameter to
make, the value specified on the command line will override our value.
In particular this can happen if the kernel Makefile is driven by an
external Makefile that uses TARGET for something.
This leads to weird build failures, eg:
nonsense at /build/linux/drivers/crypto/vmx/ghashp8-ppc.pl line 45.
/linux/drivers/crypto/vmx/Makefile:20: recipe for target 'drivers/crypto/vmx/ghashp8-ppc.S' failed
Which shows that we passed an empty value for $(TARGET) to the perl
script, confirmed with make V=1:
perl /linux/drivers/crypto/vmx/ghashp8-ppc.pl > drivers/crypto/vmx/ghashp8-ppc.S
We can avoid this confusion by using override, to tell make that we
don't want anything to override our variable, even a value specified
on the command line. We can also use a less common name, given the
script calls it "flavour", let's use that.

In case of in-place decryption, the "lastc" buffer is used to copy
the last ciphertext block before the decryption of the message. It
is later used to update the req->iv of the skcipher_request.
"lastc" variable is not used to interact with the hardware, there
is no restriction to be of type "u32". Change the type of "lastc"
to "u8".

The req->iv of the skcipher_request is expected to contain the

In case of in-place decryption, copy the ciphertext in an
intermediate buffer before decryption.

Currently, there is no privilege separation of the SEV command; you can
run them all or none of them. This is less than ideal because it means
that a compromise of the code which launches VMs could make permanent
change to the SEV certifcate chain which will affect others.
These commands are required to attest the VM environment:
- SEV_PDH_CERT_EXPORT
- SEV_PLATFORM_STATUS
- SEV_GET_{ID,ID2}
These commands manage the SEV certificate chain:
- SEV_PEK_CERR_IMPORT
- SEV_FACTORY_RESET
- SEV_PEK_GEN
- SEV_PEK_CSR
- SEV_PDH_GEN
Lets add the CAP_SYS_ADMIN check for the group of the commands which alters
the SEV certificate chain to provide some level of privilege separation.

Commit 7a7ffe65c8 ("crypto: skcipher - Add top-level skcipher interface")

been converted long ago, some producers of the ablkcipher remain, forcing
us to keep the ablkcipher support routines alive, along with the matching
code to expose [a]blkciphers via the skcipher API.
So switch this driver to the skcipher API, allowing us to finally drop the

dated 20 august 2015 introduced the new skcipher API which is supposed to
replace both blkcipher and ablkcipher. While all consumers of the API have
been converted long ago, some producers of the ablkcipher remain, forcing
us to keep the ablkcipher support routines alive, along with the matching
code to expose [a]blkciphers via the skcipher API.
So switch this driver to the skcipher API, allowing us to finally drop the
ablkcipher code in the near future.

Historically linux tried to stick to RFC 791, 1122, 2003
for IPv4 ID field generation.
RFC 6864 made clear that no matter how hard we try,
we can not ensure unicity of IP ID within maximum
lifetime for all datagrams with a given source
address/destination address/protocol tuple.
Linux uses a per socket inet generator (inet_id), initialized
at connection startup with a XOR of 'jiffies' and other
fields that appear clear on the wire.
Thiemo Nagel pointed that this strategy is a privacy
concern as this provides 16 bits of entropy to fingerprint
devices.
Let's switch to a random starting point, this is just as
good as far as RFC 6864 is concerned and does not leak
anything critical.

The .ioctl and .compat_ioctl file operations have the same prototype so
they can both point to the same function, which works great almost all
the time when all the commands are compatible.
One exception is the s390 architecture, where a compat pointer is only
31 bit wide, and converting it into a 64-bit pointer requires calling
compat_ptr(). Most drivers here will never run in s390, but since we now
have a generic helper for it, it's easy enough to use it consistently.
I double-checked all these drivers to ensure that all ioctl arguments
are used as pointers or are ignored, but are not interpreted as integer
values.
