move asm/unaligned.h to linux/unaligned.h

2024-10-02T21:23:23+00:00

asm/unaligned.h is always an include of asm-generic/unaligned.h;
might as well move that thing to linux/unaligned.h and include
that - there's nothing arch-specific in that header.

auto-generated by the following:

for i in `git grep -l -w asm/unaligned.h`; do
	sed -i -e "s/asm\/unaligned.h/linux\/unaligned.h/" $i
done
for i in `git grep -l -w asm-generic/unaligned.h`; do

git mv include/asm-generic/unaligned.h include/linux/unaligned.h

nvme-tcp: check for invalidated or revoked key

2024-08-22T20:25:07+00:00

key_lookup() will always return a key, even if that key is revoked
or invalidated. So check for invalid keys before continuing.

nvme-keyring: restrict match length for version '1' identifiers

2024-08-22T20:22:41+00:00

TP8018 introduced a new TLS PSK identifier version (version 1), which appended
a PSK hash value to the existing identifier (cf NVMe TCP specification v1.1,
section 3.6.1.3 'TLS PSK and PSK Identity Derivation').
An original (version 0) identifier has the form:

NVMe0  

and a version 1 identifier has the form:

NVMe1   

This patch modifies the lookup algorthm to compare only the first part
of the identifier (excluding the hash value) to handle both version 0 and
version 1 identifiers.
And the spec declares 'version 0' identifiers obsolete, so the lookup
algorithm is modified to prever v1 identifiers.
