* sm-notify: Notify hosts in backgroundSteve Dickson2015-01-151-3/+2

* systemd: Bind the nfs-mountd service to the nfs-server serviceSteve Dickson2015-01-151-2/+1
| | | | | | | | | | | | | | | Use BindsTo, instead of PartOf, to bind the rpc-mountd service to the nfs-server service. Its a much tighter bind than PartOf. The Partof=nfs-utils.service was not needed. One side effect of this tighter bond is when rpc.mountd is stop, that will also bring the nfs server down as well, due to the Requires=nfs-mountd.service in the nfs-server service Signed-off-by: Steve Dickson <steved@redhat.com>
* systemd: Bind rpc.idmapd to the nfs-server serviceSteve Dickson2015-01-151-1/+1
| | | | | | | | | Since rpc.idmapd is only used by the nfs server, to do its id mapping, bind the rpc-idmapd service to the nfs-server service so rpc.idmapd will started and stopped with the server. Signed-off-by: Steve Dickson <steved@redhat.com>

* mountstats: Add support for -S/--sinceScott Mayhew2014-12-131-13/+38
| | | | | | | | | | Add support for -S/--since to display the delta between a previous copy of /proc/self/mountstats and the current /proc/self/mountstats file. Can be combined with the -f option to show the statistics between two different points in time. Signed-off-by: Scott Mayhew <smayhew@redhat.com> Signed-off-by: Steve Dickson <steved@redhat.com>

* mountstats: Make the iostat sub-command output match that of nfs-iostat.pyScott Mayhew2014-12-131-43/+61

* mountstats: Convert existing option parsing to use the argparse moduleScott Mayhew2014-12-131-144/+110
| | | | | | | | | | | | | | Made mountstats, nfsstat, and iostat all subcommands (note that the nfsstat function is still unimplemented here). If no sub-command is given, then the mountstats sub-command will run by default (so any scripts that run older versions of the mountstats command will still work). Also removed the --start and --end options since all they do is throw exceptions. Signed-off-by: Scott Mayhew <smayhew@redhat.com> Signed-off-by: Steve Dickson <steved@redhat.com>

Also compute the difference of every counter where it makes sense -- this will allow support for -S/--since to be implemented in the future.

* mountstats: Add lists of various countersScott Mayhew2014-12-131-0/+168
| | | | | | | | | | The NfsEventCounters and NfsByteCounters were lifted straight from nfs-iostat.py. Also added counters for the xprt line (for udp, tcp, and rdma) as well as for v3 and v4 NFS ops. These will allow for more compact code in a couple of places. Signed-off-by: Scott Mayhew <smayhew@redhat.com> Signed-off-by: Steve Dickson <steved@redhat.com>
* mountstats: Fix up NFS event countersScott Mayhew2014-12-131-15/+18

* configure: use pkg-config to find libtirpcYann E. MORIN2014-12-131-55/+12
| | | | | | | | | | | | | | | | | | | | | | | | Currently, we use a custom function to find libtirpc's headers and libraries. This works fine for shared linking. But for static linking, this forgets to link with -lpthread, which is required by libtirpc. A recent patch was sent to libtirpc to add that missing -lpthread in its Libs.private section of its .pc file. Thus, pkg-config will soon be able to return the appropriate libraries. So, use pkg-config to find libtirpc. And for older libtirpc versions, there is no change in behaviour: we're still missing the -lpthread. But once libtirpc has been fixed, we'll automatically get that missing library for free! Remove the --with-libirpc flag as it is no longer needed: pkg-config will provide us with the -I and -L flags, now. Signed-off-by: "Yann E.

* gssd: fix gssd build flagsDavid Hardeman2014-12-081-2/+2
| | | | | | | | | The tirpc variable is another library to add, not additional flags. I'm guessing the reason this hasn't caused problems is that it only shows up with static libraries. Signed-off-by: David Hardeman <david@hardeman.nu> Signed-off-by: Steve Dickson <steved@redhat.com>

* nfsdcltrack: use sqlite3_errmsg instead of sqlite3_errstrJeff Layton2014-11-171-6/+6
| | | | | | | | | sqlite3_errstr was only added in v3.7.15 of libsqlite3, which makes it difficult to build against earlier releases. Switch the code over to use sqlite3_errmsg instead. Signed-off-by: Jeff Layton <jlayton@primarydata.com> Signed-off-by: Steve Dickson <steved@redhat.com>
* nfsdcltrack: use sqlite3_close instead of sqlite3_close_v2Jeff Layton2014-11-171-1/+1
| | | | | | | | | | | | | | sqlite3_close_v2 wasn't added until v3.7.14 of libsqlite3 so this causes the build to fail vs. very old sqlite3 libs. Also, Chuck points out that the documentation says that sqlite3_close_v2 is intended for use with host languages that are garbage collected, and C isn't. In practice, we shouldn't ever see sqlite3_close return SQLITE_BUSY here anyway since the program is single-threaded, so sqlite3_close should be fine.

* exportfs: Do not fail on empty exports file.Steve Dickson2014-11-173-9/+16

* mountstats: Fix spurious I/O errorsChuck Lever2014-11-171-0/+4
| | | | | | | | | | | | | | | | | When running mountstats under "watch," occassionally the output shows "close failed in file object desctructor: sys.excepthook is missing" and the data display is messed up. This seems to be a common problem when Python script output is piped to another program. Ensure stdout/stderr is completely flushed before mountstats exits, and add an IOError exception handler to catch these exceptions gracefully.

* rpc.mountd: set libtirpc nonblocking mode to avoid DOSBodo Stroesser2014-11-121-0/+17
| | | | | | | | | | | | | | | This patch is experimental. In works fine in that it removes the vulnerability against a DOS attack. rpc.mountd can be blocked by a bad client, that sends many RPC requests but never reads the responses. This might happen intentionally or caused by a wrong network config (MTU). The patch switches on the nonblocking mode of libtirpc. In that mode writes can block for a max of 2 seconds. Attackers are forced to send requests slower, as libtirpc will close a connection if it finds two requests to read at the same time.
