Geert reports that: > On v6.2, "make ARCH=m68k defconfig" gives you > CONFIG_RPCSEC_GSS_KRB5=m > On v6.3, it became builtin, due to dropping the dependencies on > the individual crypto modules. > > $ grep -E "CRYPTO_(MD5|DES|CBC|CTS|ECB|HMAC|SHA1|AES)" .config > CONFIG_CRYPTO_AES=y > CONFIG_CRYPTO_AES_TI=m > CONFIG_CRYPTO_DES=m > CONFIG_CRYPTO_CBC=m > CONFIG_CRYPTO_CTS=m > CONFIG_CRYPTO_ECB=m > CONFIG_CRYPTO_HMAC=m > CONFIG_CRYPTO_MD5=m > CONFIG_CRYPTO_SHA1=m This behavior is triggered by the "default y" in the definition of RPCSEC_GSS. The "default y" was added in 2010 by commitdf486a2590("NFS: Fix the selection of security flavours in Kconfig"). However, svc_gss_principal was removed in 2012 by commit03a4e1f6dd("nfsd4: move principal name into svc_cred"), so the 2010 fix is no longer necessary. We can safely change the NFS_V4 and NFSD_V4 dependencies back to RPCSEC_GSS_KRB5 to get the nicer v6.2 behavior back. Selecting KRB5 symbolically represents the true requirement here: that all spec-compliant NFSv4 implementations must have Kerberos available to use.

Solaris NFS servers support an auxiliary NFSv3 ACL protocol that
|
|
never became an official part of the NFS version 3 protocol.
|
|
This protocol extension allows applications on NFS clients to
|
|
manipulate POSIX Access Control Lists on files residing on NFS
|
|
servers. NFS servers enforce POSIX ACLs on local files whether
|
|
this protocol is available or not.
|
|
|
|
This option enables support in your system's NFS server for the
|
|
NFSv3 ACL protocol extension allowing NFS clients to manipulate
|
|
POSIX ACLs on files exported by your system's NFS server. NFS
|
|
clients which support the Solaris NFSv3 ACL protocol can then
|
|
access and modify ACLs on your NFS server.
|
|
|
|
To store ACLs on your NFS server, you also need to enable ACL-
|
|
related CONFIG options for your local file systems of choice.
