* Determine supported pseudoflavors from exportJ. Bruce Fields2008-08-281-17/+38
| | | | | | | | Instead of using a static list of supported flavors, we should be taking the list from the export. Signed-off-by: J. Bruce Fields <bfields@citi.umich.edu> Signed-off-by: Steve Dickson <steved@redhat.com>
* Minor mountd.c cleanupJ. Bruce Fields2008-08-281-38/+49
| | | | | | | | | I find it more readable to have the normal (non-error) case unindented, and to keep conditionals relatively simple, as is the usual kernel style. Fix some inconsistent indentation while we're there. Signed-off-by: J. Bruce Fields <bfields@citi.umich.edu> Signed-off-by: Steve Dickson <steved@redhat.com>
* Remove redundant m_path fieldJ. Bruce Fields2008-08-281-10/+2
| | | | | | | | | | | | | | | | | Contrary to the comment above its definition, the field m_path always has the same value as e_path: the *only* modifications of m_path are all of the form: strncpy(exp->m_export.m_path, exp->m_export.e_path, sizeof (exp->m_export.m_path) - 1); exp->m_export.m_path[sizeof (exp->m_export.m_path) - 1] = '\0'; So m_path is always just a copy of e_path. In places where we need to store a path to a submount of a CROSSMNT-exported filesystem, as in cache.c, we just use a local variable. Signed-off-by: J.

* There were 2 things wrong with auth flavour ordering:bc Wong2008-03-181-1/+8
| | | | | | | | | | | | | | | | | | | | | | - Mountd used to advertise AUTH_NULL as the first flavour on the list, which means that it prefers AUTH_NULL to anything else (as per RFC 2623 section 2.7). - Mount.nfs used to scan the returned list in reverse order, and stopping at the first AUTH_NULL or AUTH_SYS encountered. If a server advertises (AUTH_SYS, AUTH_NULL), it will by default choose AUTH_NULL and have degraded access. I've fixed mount.nfs to scan from the beginning. For mountd, it does not advertise AUTH_NULL anymore. This is necessary to avoid backward compatibility issue. If AUTH_NULL appears in the list, either the new or the old client will choose that over AUTH_SYS. Tested the server/client combination against the previous versions, as well as Solaris and FreeBSD.

* In mountd, if get_exportlist() (utils/mountd/mountd.c) returns NULL itHarshula Jayasuriya2008-02-121-9/+7
| | | | | | | | | | | | | | should not be considered a failure. It just means that there are no exports on the system. The practical problem with the current code is that a showmount -e results in a syslog message from mountd that looks like: rpc.mountd: export request from 10.250.100.2 failed.

* rpc.mountd: add new mode for handling netgroup-heavy configurationsJeff Layton2007-09-281-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If a host is a member of a large number of netgroups, it becomes easily possible for client_compose to generate a m_hostname string that overflows the maximum string length allowed by the kernel caches. This patch adds a new mode for mountd where it will map IP address to IP address in the auth.unix.ip cache. When this enabled, mountd doesn't bother using client_compose to build the m_hostname string. It just populates it with the dotted-quad ip address. When mountd handles a mount request, it then has an IP address and a path. It then calls client_check to check the host against export entries where the path has already matched. Since we don't bother looking up netgroups which have no relation to the mount, this can be a big performance gain in netgroup-heavy configurations. The downside is that every host has a corresponding entry in the nfsd.export and nfsd.fh caches as well as the auth.unix.ip cache. The new behavior is automatically enabled if the length of all of the concatenated netgroup names in the export table is longer than half NFSCLNT_IDMAX. The rationale for this logic is that this should allow for a host to be a member of a long list of netgroups while still allowing for other matches.

* nfs-utils: have mountd hold open etab file to force inode number to changeJeff Layton2007-05-111-5/+5
| | | | | | | | | | | | | This patch changes mountd to hold the etab file open so that when it's changed by exportfs, the inode number should change. We then change auth_reload to reload the file based on whether st_ino is different from the last time it was checked. It also changes auth_reload to maintain a static counter value and return it instead of a timestamp and fixes up get_exportlist accordingly. Finally, it adds some comments to xtab_write to warn people about editing the etab in place. Signed-off-by: Jeff Layton <jlayton@redhat.com> Signed-off-by: NeilBrown <neilb@suse.de>
* Allow exporting of a subfilesystem when 'crossmnt' is set.Neil Brown2007-03-191-3/+3
| | | | | | | | | If we are asked to export a filesystem which is not explicitly exported, but an ancestor is exported as 'crossmnt', export the filesystems with the same options as the ancestor. This is the first step to making 'crossmnt' effectively export a tree of filesystems.
* Support group-id looks for kernels that ask for them.Neil Brown2007-02-121-2/+7
| | | | | | | With "-g" mountd will listen for uid -> gidlist requests from the kernel and provide the required mapping. This is specific to AUTH_USER (aka AUTH_SYS) and is designed to overcome the 16-gid limit in the AUTH_UNIX protocol.
* Ensure 'showmount -e' gets current information.Neil Brown2007-01-111-1/+6
| | | | | | If auth_reload has been called by someone else, get_exportlist can incorrectly return old data. So track modify times better and only use cached data if the modify time matches.
* Error check messages sent to the kernel.Neil Brown2007-01-111-2/+5
| | | | | | 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

* add -r flag to make mountd do reverse resolve of ipaddress on the flyJeff Layton2006-12-191-1/+5
| | | | | | | | | | | | | 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 Layton2006-12-191-9/+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.

* Fix -n option to mountdSteinar H. Gunderson2006-10-241-1/+1

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
