From ffc40f569272b6be60c66441aeae79a686ff54d9 Mon Sep 17 00:00:00 2001 From: Kevin Coffman Date: Fri, 9 Nov 2007 18:42:04 -0500 Subject: sunrpc: gss_pipe_downcall(), don't assume all errors are transient Instead of mapping all errors except EACCES to EAGAIN, map all errors except EAGAIN to EACCES. An example is user-land negotiating a Kerberos context with an encryption type that is not supported by the kernel code. (This can happen due to mis-configuration or a bug in the Kerberos code that does not honor our request to limit the encryption types negotiated.) This failure is not transient, and returning EAGAIN causes mount to continuously retry rather than giving up.
