* Error check messages sent to the kernel.Neil Brown2007-01-112-13/+21
| | | | | | And make sure that if we fail to export a filesystem in mountd, then we don't try to get a filehandle on it, or a deadlock might occur.
* add missing long option for -r in mountdJeff Layton2006-12-201-0/+1
| | | | | | | | | I forgot a bit of code that needs to go into patch 3 that I posted yesterday. This adds a long option for the -r option. I'll post manpage update patches once I get them written up. Signed-off-by: Jeff Layton <jlayton@redhat.com> Signed-off-by: Neil Brown <neilb@suse.de>
* add -r flag to make mountd do reverse resolve of ipaddress on the flyJeff Layton2006-12-192-3/+18
| | | | | | | | | | | | | For those that want "traditional" showmount -a behavior from their mountd (hostname:/path instead of ipaddr:/path). This patch adds a '-r' flag that does a reverse-resolve for each IP address listed in the rmtab when a dump operation is called. Probably not a good idea for those concerned about performance, but since it's not the default option, I don't see it being an issue.

* remove extraneous mountlist_add/del calls and change remaining ones to use ↵Jeff Layton2006-12-192-18/+8
| | | | | | | | | | | | | | | | | | | | | | IP addresses Neil suggested a patch to change the mountlist_add and mountlist_del calls to use IP addresses instead of the names returned by client_compose based on a command line option flag. I don't see any real reason to put client_compose strings into the rmtab, so this patch makes it so that it adds IP addresses instead of those strings to the rmtab by default. It also removes all mountlist_add calls that are being done from kernel cache routines. My main concern there is NFSv4. We don't seem to make any upcalls to mountd on NFSv4 unmounts, and I don't see a way to reliably remove NFSv4 entries. So, I figured I'd stick with having mountlist_add only called when a v2 or v3 mount call is made, and mountlist_del called only on the corresponding unmount call.

* Don't rely on old info in my_clientJeff Layton2006-12-191-15/+9
| | | | | | | | | | | | | | | | | | | | | | | Here's a new set of patches to fix up "showmount -a", based on the approach suggested by Neil. This first patch is fairly simple. It just stops the current caching of my_client. For an explanation, consider this situation with the current code: 1) Client mounts an NFS export from server that is restricted to a particular hostname or netgroup. 2) DNS or netgroup changes so that the client would be denied. 3) Client attempts mount again. Mount succeeds, even though it shouldn't due to the fact that mountd relies on cached info in my_client. This situation can occur as long as no other client attempts a mount between 1 and 3 above. The patch below removes this caching, and causes a new invocation of client_compose for each pass through auth_authenticate: Signed-off-by: Jeff Layton <jlayton@redhat.com> Signed-off-by: Neil Brown <neilb@suse.de>
* Fix -n option to mountdSteinar H. Gunderson2006-10-241-1/+1
| | | | | | | The getopt_long() option string in mountd was having a spurious colon after the 'n', leading to the short form of --no-tcp not being usable (expecting a parameter, contrary to the long form and the documentation). Fix.

* multiple threads for mountdGreg Banks2006-06-162-9/+121
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | How about the attached patch against nfs-utils tot? It adds a -t option to set the number of forked workers. Default is 1 thread, i.e. the old behaviour. I've verified that showmount -e, the Ogata mount client, and a real mount from Linux and IRIX boxes work with and without the new option. I've verified that you can manually kill any of the workers without the portmap registration going away, that killing all the workers causes the manager process to wake up and unregister, and killing the manager process causes the workers to be killed and portmap unregistered. I've verified that all the workers have file descriptors for the udp socket and the tcp rendezvous socket, that connections are balanced across all the workers if service times are sufficiently long, and that performance is improved by that parallelism, at least for small numbers of threads. For example, with 60 parallel MOUNT calls and a testing patch to make DNS lookups take 100 milliseconds time to perform all mounts (averaged over 5 runs) is: num elapsed threads time (sec) ------ ---------- 1 13.125 2 6.859 3 4.836 4 3.841 5 3.303 6 3.100 7 3.078 8 3.018 Greg. -- Greg Banks, R&D Software Engineer, SGI Australian Software Group.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | *utils/mountd/mountd.c: mountd currently always returns AUTH_NULL and AUTH_SYS as the allowable flavors in mount replies. We want it to also return gss flavors when appropriate. For now as a hack we just have it always return the KRB5 flavors as well. *utils/mountd/cache.c: When attempting to mount an NFSv4 pseudofilesystem (fsid=0) and the actual exported directory does not exist on the server, rpc.mountd doesn't check the directory exists (when fsidtype=1, i.e. using fsid, but does check for fsidtype=0, i.e. using dev/ino). The non-existent exported directory path with fsid=0 is written to the kernel via /proc/net/rpc/nfsd.export/channel, which leads to path_lookup() to return ENOENT (seems appropriate). Unfortunately, the new_cache approach ignores errors returned when writing via the channel file so that particular error is lost and the mount request is silently ignored. Assuming it doesn't make sense to revamp the new_cache/up-call method to not ignore returned errors, it seems appropriate to fix the case where rpc.mountd doesn't check for the existence of an exported directory with fsid= semantics. The following patch does this by moving the stat() up so it is done for both fsidtype's. I'm not certain whether the other tests need to be executed for fsidtype=1, but it doesn't appear to hurt [Not exactly true: the comparison of inode numbers caused problems so now it's kept for fsidtype=0 only]. Would it be also desirable to log a warning for every error, if any, returned by a write to any of the /proc/net/rpc/*/channel files which would otherwise be ignored (maybe under a debug flag)? * gssd/mountd/svcgssd: Changes gssd, svcgssd, and mountd to ignore a SIGHUP rather than dying. * many: Remove the gssapi code and rely on an external library instead.
