* rpc.statd: Stop overloading sockfd in utils/statd/rmtcall.cChuck Lever2008-09-261-12/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Linux kernel's lockd requires that rpc.statd perform notification callbacks from a privileged source port. To guarantee rpc.statd gets a privileged source port but runs unprivileged, it calls statd_get_socket() then drops root privileges before starting it's svc request processing loop. Statd's svc request loop is the only caller of the process_foo() functions in utils/statd/rmtcall.c, but one of them, process_notify_list() attempts to invoke statd_get_socket() again. In today's code, this is unneeded because statd_get_socket() is always invoked before my_svc_run(). However, if it ever succeeded, it would get an unprivileged source port anyway, causing the kernel to reject all subsequent requests from statd. Thus the process_notify_list() function should not ever call statd_get_socket() because root privileges have been dropped by this point, and statd_get_socket() wouldn't get a privileged source port, causing the kernel to reject all subsequent SM_NOTIFY requests. So all of the process_foo functions in utils/statd/rmtcall.c should use the global sockfd instead of a local copy, as it already has a privileged source port. I've seen some unexplained behavior where statd starts making calls to the kernel via an unprivileged port. This could be one way that might occur.

* rpc.statd: Use __func__ in dprintfChuck Lever2008-09-261-23/+27
| | | | | | | | | | | | Clean up: The named function in many of the debugging messages in utils/statd/rmtcall.c is out of date. To prevent this from happening in the future, replace these with __func__. Also, note() and dprintf() do not require a terminating '\n' in their format string. So make all invocations consistent.

* Be more cautious about use for privilege ports (<1024).Neil Brown2007-04-161-11/+23
| | | | | | | | | | | | | Ports < 1024 are a scarce resource and should not be used carelessly. Technically they should be not used at all without registration with IANA, but sometimes we need them despite that. So: for the socket that RPC services listen on, don't use a <1024 port by default. There is no need. For sockets that we send messages on, that are long-lived, and that might need to appear 'privileged', avoid using a number that is registered in /etc/services if possible.
* statd - remove try_to_resolveNeil Brown2007-03-201-60/+2
| | | | | | try_to_resolve is used to resolve a hostname when sending a notification. But we now only send notifications to localhost, so name resolution is not needed.
* Remove notify functionality from statd in favour of sm-notifyNeil Brown2007-03-201-132/+19
| | | | | statd now execs sm-notify to notify peers and only listens to monitor requests and remote notifications itself.
