* config: Remove the conf_path globalJustin Mitchell2017-05-051-2/+1
| | | | | | | | Working towards an nfs.conf library and API for system config tools, first step, replace the conf_path global with a parameter to conf_init Signed-off-by: Justin Mitchell <jumitche@rehat.com> Signed-off-by: Steve Dickson <steved@redhat.com>
* xlog: Add common support for "debug=??" in /etc/nfs.confNeilBrown2016-12-201-0/+1
| | | | | | | | The value is from the list general, call, auth, parse, all. Most daemons recognise this in their dedicated section. Signed-off-by: NeilBrown <neilb@suse.com> Signed-off-by: Steve Dickson <steved@redhat.com>
* statd: allow --no-notify to be passed via environment variable.NeilBrown2016-12-201-0/+5
| | | | | | | | | | The significant value of allowing this is that it means that for default operation, systemd unit files do not need to pass any options to any programs. The purpose of this will become apparent in the next patch. Signed-off-by: NeilBrown <neilb@suse.com> Signed-off-by: Steve Dickson <steved@redhat.com>

* Remove error messages on xstrdup failure.NeilBrown2016-12-061-4/+1
| | | | | | | | | | | | xstrdup() prints a messages and exits, except in statd where is prints a message and fails. So there is no point printing an extra message when xstrdup() fails, and except in statd, no point calling exit() as well. So remove some pointless code.

* statd: fix a segfault caused by improper usage of RPC interfaceShan Hai2015-11-021-2/+3
| | | | | | | | | | | | | | There is a hack which uses the bottom-level RPC improperly as below in the current statd implementation: insert a socket in the svc_fdset without a corresponding transport handle and passes the socket to the svc_getreqset subroutine, this usage causes a segfault of statd on a huge amount of sm-notifications. Fix the issue by separating the non-RPC-server socket from RPC dispatcher. Signed-off-by: Shan Hai <shan.hai@windriver.com> Signed-off-by: Steve Dickson <steved@redhat.com>

* cleanup daemonization codeDavid Hardeman2015-01-231-55/+11
| | | | | | | | | | | | | | | The daemonization init/ready functions have parameters that are never used, require the caller to keep track of some pipefds that it has no interest in and which might not be used in some scenarios. Cleanup both functions a bit. The idea here is also that these two functions might be good points to insert more systemd init code later (sd_notify()). Also, statd had a private copy of the daemonization code for unknown reasons...so make it use the generic version instead.

* statd: add options to set port number of lockdNeilBrown2014-03-111-3/+54
| | | | | | | | | | | Even though lockd is a totally separate process to statd, they depended on each other: statd much be running for lockd to be useful. So an easy way to set the port numbers used by lockd is to get statd to set them. This patch add --nlm-port and --nlm-tcp-port to that end. Signed-off-by: Steve Dickson <steved@redhat.com>

* utils: Return status 0 on clean exitsMantas Mikulenas2012-10-151-1/+2

* tcpwrapper: Add support for IPv6Chuck Lever2010-01-171-4/+1
| | | | | | | | | | Assuming the tcp_wrappers library can actually support IPv6 addresses, here's a crack at IPv6 support in nfs-utils' TCP wrapper shim. Some reorganization is done to limit the number of times that @sap is converted to a presentation address string. Signed-off-by: Chuck Lever <chuck.lever@oracle.com>
* tcp_wrapper: Clean up logit()Chuck Lever2010-01-171-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | Eliminate these compiler warnings: tcpwrapper.c: In function logit tcpwrapper.c:225: warning: unused parameter procnum tcpwrapper.c:225: warning: unused parameter prognum Actually, @procnum is not used anywhere in our tcpwrapper.c, so let's just get rid of it. Since there is only one logit() call site in tcpwrapper.c, the macro wrapper just adds needless clutter. Let's get rid of that too. Finally, both mountd and statd now use xlog(), which adds an appropriate program name prefix to every message. Replace the open-coded syslog(2) call with an xlog() call in order to consistently identify the RPC service reporting the intrusion. Since logit() no longer references "deny_severity" and no nfs-utils caller sets either allow_severity or deny_severity, we remove them.

* statd: Support TI-RPC statd listenerChuck Lever2010-01-151-7/+31
| | | | | | | | | | | | | | | | | | | | If TI-RPC is available, use it to create statd's svc listener. If not, use the old function, rpc_init(), to create statd's listener. IPv6 can be supported if TI-RPC is available. In this case, /etc/netconfig is searched to determine which transports to advertise. Add the new listener creation API in libnfs.a since other components of nfs-utils (such as rpc.mountd) will eventually want to share it. A little re-arrangement of when the statd listener is created is done to make unregistration of the statd service more reliable. As it is now, the statd service is never unregistered when it exits. After it is gone, other programs usually hang when trying to access statd or see if it's running, since the registration is still there but statd itself does not respond.

* statd: Use the new nsm_ file.c calls in rpc.statdChuck Lever2010-01-121-104/+12
| | | | | | | | | | Replace open-coded accesses to on-disk NSM information in rpc.statd with calls to the new API. Behavior should be much the same as it was before. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: Steve Dickson <steved@redhat.com>
* statd: Replace note() with xlog() in rpc.statdChuck Lever2009-11-241-31/+26
| | | | | | | | | | | To facilitate code sharing between statd and sm-notify (and with other components of nfs-utils), replace sm-notify's nsm_log() with xlog(). Since opt_quiet is used in only a handful of insignificant cases, it is removed. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: Steve Dickson <steved@redhat.com>
* In recent Fedora builds, the '-D _FORTIFY_SOURCE=2' compileSteve Dickson2009-03-231-11/+29

* nfs-utils: Provide type-checked version of svc_getcaller()Chuck Lever2009-03-051-2/+4
| | | | | | | | | | | | | TI-RPC's version of the svc_getcaller() macro points to a sockaddr_in6, not a sockaddr_in, though for AF_INET callers, an AF_INET address resides there. To squelch compiler warnings when the TI-RPC version of the svc_req structure is used, add inline helpers with appropriate type casting. Note that tcp_wrappers support only AF_INET addresses for now.

* rpc.statd: Stop overloading sockfd in utils/statd/rmtcall.cChuck Lever2008-09-261-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Tell NFS/lockd client what that local state number is.Neil Brown2007-04-021-1/+22
| | | | | | | | | | | | Both SM_STAT and SM_MON can return the state of an NSM, but it is unclear which NSM they return the state of, so the value cannot be used, and lockd doesn't use it. Document this confusion, and give the current state to the kernel via a sysctl if that sysctl is available (since about 2.6.19). This should make is possible for the NFS server to detect a small class of bad SM_NOTIFY packets and not flush locks in that case. Signed-off-by: Neil Brown <neilb@suse.de>
* statd - only unregister/register once.Neil Brown2007-03-291-16/+13
| | | | | | | | | | | | | The for loop that restarts on SIGUSR or simu_reboot currently includes several once-only things, that are probably best taken out of the loop. We also take the unregister/register out of the loop as if statd does drop privileges, then the second register won't use a privileged port properly. On the whole, cleaner code. Signed-off-by: Neil Brown <neilb@suse.de>
* statd - keep persistent state in sm/* files.Neil Brown2007-03-291-0/+6
| | | | | | | | | | | | If statd dies and is restarted, it forgets what peers the kernel is interested in monitoring, and so will not forward NOTIFY requests properly. With this patch the required information is recorded in the files in /var/lib/nfs/sm/* so that a kill/restart does what you might hope. Signed-off-by: Neil Brown <neilb@suse.de>
* statd - fix bug so statd can talk to kernel again.Neil Brown2007-03-231-0/+2
| | | | | | | We need to call statd_get_socket before dropping privileges so that we have a privileged port. We use to do that when initialising notification as the same socket was used for reboot notication as for callbacks to the kernel. Now it is a different socket..
* Fix errors in statd calling sm-notify.Neil Brown2007-03-221-4/+5
| | | | | | The option for set-source-address is '-v', not '-N'. And only warn about -N if -N was actually used.
* statd - delay drop-privs until sockets have been setup.Neil Brown2007-03-201-1/+5
| | | | | Registering sockets with portmap might require root privs, so don't drop privs until that has been done.
* Allow rpc.statd to *not* run sm-notify.Neil Brown2007-03-201-19/+27
| | | | | With -L (for Listen-only) or --no-notify, statd will not run sm-notify.
* Remove notify functionality from statd in favour of sm-notifyNeil Brown2007-03-201-35/+62
