Rick Macklem 04cb0c38eb Add a cap on credential lifetime for Kerberized NFS.
The kernel RPCSEC_GSS code sets the credential (called a client) lifetime
to the lifetime of the Kerberos ticket, which is typically several hours.
As such, when a user's credentials change such as being added to a new group,
it can take several hours for this change to be recognized by the NFS server.
This patch adds a sysctl called kern.rpc.gss.lifetime_max which can be set
by a sysadmin to put a cap on the time to expire for the credentials, so that
a sysadmin can reduce the timeout.
It also fixes a bug, where time_uptime is added twice when GSS_C_INDEFINITE
is returned for a lifetime. This has no effect in practice, sine Kerberos
never does this.

FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.
