gssd: fix crash in debug message.
|
|
|
381c0b |
|
|
|
381c0b |
A recent cleanup of debug messages added func and tid format specifiers
|
|
|
381c0b |
to a debug message (when full hostname was different), but the func name
|
|
|
381c0b |
and tid were NOT added as arguments.
|
|
|
381c0b |
|
|
|
381c0b |
Consequently there weren't enough args, random bytes of the stack were
|
|
|
381c0b |
interpreted as a pointer, and rpc.gssd crashed (when -v was specified).
