QEMU executes the `smbd` process in [slirp.c](net/slirp.c) to facilitate the SMB sharing between guest and host. The host `smbd` process links in GnuTLS for authentication ciphers and algorithm primitives. When `smbd` processes SMB requests from these older OS's SMB implementations, it errors out with error lines: `Failed to setup SPNEGO negTokenInit request` `Failed to start SPNEGO handler for negprot OID list!` Steps to reproduce: 1. Access a GNU+Linux machine with GnuTLS library in FIPS mode which `smbd` links against 2. Run `qemu-system-*` with an older guest OS with a `smb` share to host 3. See errors in `/tmp/qemu.smb*/log.smbd` Additional information: #
