  Revert "SUNRPC: Make RPCSEC_GSS_KRB5 select CRYPTO instead of depending on it" (2025-11-10 09:31:52 -0500)

----------------------------------------------------------------
nfsd-6.18 fixes:

Address recently reported issues or issues found at the recent NFS
bake-a-thon held in Raleigh, NC.

Issues reported with v6.18-rc:
- Address a kernel build issue
- Reorder SEQUENCE processing to avoid spurious NFS4ERR_SEQ_MISORDERED

Issues that need expedient stable backports:
- Close a refcount leak exposure
- Report support for NFSv4.2 CLONE correctly
- Fix oops during COPY_NOTIFY processing
- Prevent rare crash after XDR encoding failure
- Prevent crash due to confused or malicious NFSv4.1 client

----------------------------------------------------------------
Chuck Lever (3):
      NFSD: Skip close replay processing if XDR encoding fails
      NFSD: Never cache a COMPOUND when the SEQUENCE operation fails
      Revert "SUNRPC: Make RPCSEC_GSS_KRB5 select CRYPTO instead of depending on it"

      nfsd: fix refcount leak in nfsd_set_fh_dentry()
      nfsd: ensure SEQUENCE replay sends a valid reply.

Olga Kornievskaia (2):
      nfsd: add missing FATTR4_WORD2_CLONE_BLKSIZE from supported attributes
      NFSD: free copynotify stateid in nfs4_free_ol_stateid()
