[PATCH 0/2] ksmbd: harden SMB 3.1.1 compression receive path

Hi Namjae,

As requested in https://github.com/namjaejeon/ksmbd/issues/529,
please find two patches:

1) Reject Pattern_V1 on decompress when it was not negotiated.
2) Validate compression Flags before kvmalloc.

Tested on 7.2.0-070200rc5-generic.

Thanks,
Anatolii Shumak
