[OS-BUILD PATCH] configs: enable CONFIG_CRYPTO_CTS=y so cts(cbc(aes)) is available in FIPS mode
Currently the CTS algo is built as a module. This is a problem if any
ciphers using CTS are marked as FIPS-enabled and the system is booted
in FIPS mode, as dracut does not include cts.ko in the initramfs. This
change is necessary for NFS with sec=krb5{,i,p} to work in FIPS mode.
Otherwise, the following panic would result:
[ 8.462065] alg: skcipher: Failed to load transform for cts(cbc(aes)): -2
[ 8.463705] Kernel panic - not syncing: cts(cbc(aes)): cts(cbc(aes)) alg self test
failed in fips mode!
Fix this by embedding the CTS code into a kernel, the same way as Fedora
already does. This was tested by a reproducer in bz1855161 #c24, #c28.
