That flag should also be cleared in the security-flavor-specific flag fields. Otherwise the kernel detects the inconsistent flags and rejects the export. The symptoms are clients hanging the first time they export a filesystem mounted under a filesystem that was exported with something like: /exports *(crossmnt,fsid=0,sec=krb5) Signed-off-by: J.

* nfs-utils: add IPv6 support to nfsdJeff Layton2009-08-141-25/+89
| | | | | | | | | | | | | | Add support for handing off IPv6 sockets to the kernel for nfsd. One of the main goals here is to not change the behavior of options and not to add any new ones, so this patch attempts to do that. We also don't want to break anything in the event that someone has an rpc.nfsd program built with IPv6 capability, but the knfsd doesn't support IPv6. Ditto for the cases where IPv6 is either not compiled in or is compiled in and blacklisted. Signed-off-by: Jeff Layton <jlayton@redhat.com> Signed-off-by: Steve Dickson <steved@redhat.com>

* nfs-utils: convert nfssvc_setfds to use getaddrinfoJeff Layton2009-08-143-103/+212
| | | | | | | | | | | | | | | | | | | Convert nfssvc_setfds to use getaddrinfo. Change the args that it takes and fix up nfssvc function to pass in the proper args. The things that nfssvc has to do to call the new nfssvc_setfds is a little cumbersome for now, but that will eventually be cleaned up in a later patch. nfs-utils: break up the nfssvc interface Currently, the only public interface to the routines in nfssvc.c is nfssvc(). This means that we do an awful lot of work after closing stderr that could be done while it's still available. Add prototypes to the header so that more functions in nfssvc.c can be called individually, and change the nfsd program to call those routines individually.

* nfs-utils: convert rpc.nfsd to use xlog()Jeff Layton2009-08-012-48/+66
| | | | | | | | | | | | | | | | | | ...and add --debug and --syslog options. With the switch to xlog(), it becomes trivial to add debug messages, so add an option to turn them on when requested. Also, rpc.nfsd isn't a proper daemon per-se, so it makes more sense to log errors to stderr where possible. Usually init scripts take care of redirecting stderr output to syslog anyway. For those that don't, add a --syslog option that forces all output to go to syslog instead. Note that even with this option, errors encountered during option processing will still go to stderr.

* mount.nfs: rearchitect mount version/protocol negotiation logicChuck Lever2009-07-141-17/+25
| | | | | | | | | | | | | | | | | | | | Text-based mounts try a mount operation first with default settings, then negotiate via rpcbind queries and retry the mount, if the default settings don't work. This method introduces long delays in certain common scenarios, and makes it difficult to tell when it is appropriate to fail immediately or negotiate and retry. To address these behavioral regressions, make text-based mounts operate the same way that legacy mounts work. Perform rpcbind queries with short timeouts first, then use the results to determine transport, version, and port number settings for the mount. This allows the mount.nfs command to detect server settings, or whether negotiation is even possible, quickly. It also makes it simple to determine when to fail vs. when to retry.

* mount.nfs: make nfs_options2pmap return errorsChuck Lever2009-07-144-102/+227
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Up until now, nfs_options2pmap() has been passed mount options that have already gone through the kernel's parser successfully. So, it never had to check for invalid mount option values. However, we are about to pass it options that come right from the user. So nfs_options2pmap() will now need to report an error and fail if it encounters a bogus value for any of the options it cares about. ===== Note that nfs_options2pmap() will allow a bogus value for an option if the same option is specified farther to the right with a useable value. For example, if a user specifies "proto=foo,...,tcp" then nfs_options2pmap() uses "tcp" and ignores "proto=foo". However, if the options are specified in the other order: "tcp,...,proto=foo" then nfs_options2pmap() will fail. This is a simple and unambiguous extension of the "rightmost wins" rule. Since mount.nfs strips out these options out and replaces them with the rpcbind-negotiated options before invoking mount(2), the kernel should never receive bogus values for these options from mount.nfs in such cases. This is probably slightly more flexible behavior than the legacy mount implementation, but should be harmless. All mount options unrelated to pmap are ignored by nfs_options2pmap().

* mount.nfs: force rpcbind queries if options aren't specifiedChuck Lever2009-07-141-7/+11
| | | | | | | | | | | | | | | | | nfs_options2pmap() fills in default values if the passed-in mount options don't specify values. This short-circuits the version, port, and transport negotiation logic in nfs_probe_bothports(). Instead, nfs_options2pmap() should plant zeros in these pmap fields to force nfs_probe_bothports() and nfs_advise_mount() to discover, via rpcbind queries, what the server supports. This fixes some scenarios where umount.nfs fails to connect to servers that don't have all rpcbind ports open, in addition to fixing other corner cases during mount.nfs version/protocol negotiation.

* mount.nfs: If port= specifies an unregistered port, retry, then failChuck Lever2009-07-141-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Suppose a port= option is specified on the mount command line, but not enough other mount options are specified to avoid an rpcbind query to discover the NFS service. If the NFS service isn't registered on [100003, 3, "tcp", port] (even if the server is listening on the specified port), the legacy mount.nfs command fails immediately with: mount.nfs: mount to NFS server 'server' failed: RPC Error: Success What's more, this mount request should succeeded if an NFS service is registered on the specified port for another version and/or protocol. So instead, let's retry the rpcbind query with the other versions and transport protocols to be absolutely sure that port won't work with either version or transport. Then, if all fails, report: mount.nfs: mount to NFS server 'server' failed: RPC Error: Program not registered This change also affects text-based mounts that require negotiation by the mount.nfs command. Note that if the mount options specify all four pmap parameters for NFS, the rpcbind query for the NFS service is skipped entirely. The mount command then hangs and times out later if NFS service is not listening on the requested tuple. This is unchanged from previous behavior.

* mydaemon: remove closeall() calls from mydaemon()Steve Dickson2009-06-292-7/+16
| | | | | | | | | | | | | | | idmapd and svcgssd have a mydaemon() routine that uses closeall() to close file descriptors. Unfortunately, they aren't using it correctly and it ends up closing the pipe that the child process uses to talk to its parent.

* mount: remove legacy version of nfs_name_to_address()Chuck Lever2009-05-184-81/+28
| | | | | | | | | | | | | | | | | | | | | | | Currently we have two separate copies of nfs_name_to_address() since some older glibc's don't define AI_ADDRCONFIG. This means extra work to build- and run-test both functions when code is changed in this area. It is also the case that gethostbyname(3) is deprecated, and should not be used in new code. Remove the legacy code in favor of always using getaddrinfo(3). We can also get rid of nfs_name_to_address()'s @family argument as well. Note also this addresses a bug in nfsumount.c -- it was calling nfs_name_to_address() with AF_UNSPEC unconditionally, even if the legacy version of nfs_name_to_address(), which doesn't support AF_UNSPEC, was in use.

* sm-notify: Failed DNS lookups should be retriedChuck Lever2009-05-181-12/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, if getaddrinfo(3) fails when trying to resolve a hostname, sm-notify gives up immediately on that host. If sm-notify is started before network service is available on a system, that means it quits without notifying anyone. Or, if DNS service isn't available due to a network partition or because the DNS server crashed, sm-notify will simply remove all of its callback files and exit. Really, sm-notify should try harder. We know that the hostnames passed in to notify_host() have already been vetted by statd, which won't monitor a hostname that it can't resolve. So it's likely that any DNS failure we meet here is a temporary condition. If it isn't, then sm-notify will stop trying to notify that host in 15 minutes anyway. [ The host's file is left in /var/lib/nfs/sm.bak in this case, but sm.bak is not read again until the next time sm-notify runs. ] sm-notify already has retry logic for handling RPC timeouts. We can co-opt that to drive DNS resolution retries. We also add AI_ADDRCONFIG because on systems whose network startup is handled by NetworkManager, there appears to be a bug that causes processes that started calling getaddinfo(3) before the network came up to continue getting EAI_AGAIN even after the network is fully operating. As I understand it, legacy glibc (before AI_ADDRCONFIG was exposed in headers) sets AI_ADDRCONFIG by default, although I haven't checked this. In any event, pre-glibc-2.2 systems probably won't run NetworkManager anyway, so this may not be much of a problem for them.

* sm-notify: Don't orphan addrinfo structsChuck Lever2009-05-181-13/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | sm-notify orphans an addrinfo struct in its address list rotation logic if only a single result was returned from getaddrinfo(3). For each host, the first time through notify_host(), we want to send a PMAP_GETPORT request. ->ai is NULL, and retries is set to 100, forcing a DNS lookup and an address rotation. If only a single addrinfo struct is returned, the rotation logic causes a NULL to be planted in ->ai, copied from the ai_next field of the returned result. This means that the second time through notify_host() (to perform the actual SM_NOTIFY call) we do a second DNS lookup, since ->ai is NULL. The result of the first lookup has been orphaned, and extra network traffic is generated. This scenario is actually fairly common. Since we pass .ai_protocol = IPPROTO_UDP, to getaddrinfo(3), for most hosts, which have a single forward and reverse pointer in the DNS database, we get back a single addrinfo struct as a result. To address this problem, only perform the address list rotation if there is more than one element on the list returned by getaddrinfo(3).

Correspondingly, if minorver4 is a negative integer -n, the string "-4.n" is written. With the default value, minorvers4==0, the minor version setting is not changed. Note that unlike the protocol versions 2, 3, or 4. The minor version setting controls the *maximum* minor version nfsd supports. Particular minor version cannot be controlled on their own. With only minor version 1 supported at the moment the difference doesn't matter, but for future minor versions greater than 1, enabling minor version X will enable support for all minor versions 1 through X. Disabling minor version X will disable support for minor versions X and up, enabling 1 through X-1. Signed-off-by: Benny Halevy <bhalevy@panasas.com> Signed-off-by: Steve Dickson <steved@redhat.com>
