* Make UDP sockets not blockingNeil Brown2007-02-051-4/+15
| | | | | | | | | This is needs if mountd is running multithreaded else multiple threads will be blocked on a UDP port with nothing to read and so won't be able to serve up-calls from the kernel. Thanks to "Murali Krishna V" <vm.krishna@gmail.com> for highlighting the problem.
* Use memset instead of __bzero.Steinar H. Gunderson2007-02-051-1/+1
| | | | | | | | | bzero has been deprecated for years (and anything starting with __ is an internal function anyhow), and __bzero seems to have broken on ia64 not too long ago. Signed-off-by: Neil Brown <neilb@suse.de>
* Allow default options in /etc/exportsSteinar H. Gunderson2007-02-051-28/+54
| | | | | | | | | | | | | | | | | | | | | | | Implement default options in /etc/exports, to fix a long-standing wishlist bug in Debian. (The user claims the syntax matches that of OpenBSD.) This makes it possible to write "/srv/www -sync,no_subtree_check host1 host2 host3" instead of having to write (sync,no_subtree_check) over and over and over again, driving the administrator slowly mad. Such option lines can be placed anywhere on the line, and affects anything after them (I do not know if OpenBSD allows this). The patch is slightly convoluted in order to avoid triggering spurious warnings; for instance, we want "/srv/www -sync host1" to trigger a warning, but not "/srv/www -sync,no_subtree_check host1" or "/srv/www -sync host1(no_subtree_check)". There was also a suggestion for a truly global (ie. per-file) option list, but this seemed like the safest bet, given that it matches that of other implementations. Also, the man page is updated with information on the new possibilities, and an example. Signed-off-by: Steinar H. Gunderson <sesse@debian.org> Signed-off-by: Neil Brown <neilb@suse.de>
* Never set flushtime for a cache in the future.Neil Brown2007-02-051-1/+4
| | | | | | If 'etab' happens to have a timestamp in the future, this will get copied to the flush-time for various caches, and no exports will work until that time arrives. So clamp the flushtime to 'now'.
* Error check messages sent to the kernel.Neil Brown2007-01-113-7/+8
| | | | | | 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.
* "rpc.nfsd XX" should not fail if ports are already open.Neil Brown2006-08-071-1/+15
| | | | | | | | | support/nfs/nfssvc.c: if any ports are already open, don't try to open any more. This means that once nfsd is running rpc.nfsd X will just change the number of threads, not the ports in use.

| | | | Add warning of neither 'subtree_check' or 'no_subtree_check' present.
* Call nfssvc_versbits before nfssvc_setfdsSteve Dickson2006-07-081-2/+5
| | | | | nfssvc_versbits() has to be called before nfssvc_setfds() for the version processing to work correctly

| * Allow rpc.nfsd to suppress tcp or udp, and listen on a specific address.Steve Dickson2006-07-033-4/+95
| | | | | | | | | | | | | | | | | | | | -T - will suppressing listening for TCP connection. -U - will suppress UDP -H host - will only listen on that local address -p port - will listen on that port. This requires kernel patches which will hopefully be in 2.6.19 and possibly some earlier test and vendor kernels.
| * Add support for suppressing different NFS versions.Steve Dickson2006-06-263-2/+40
| | | | | | | | | | | | e.g. -N 2 means that NFSv2 won't be supported, just v3 and v4 (if the kernel supports them).

| * Fix comment parsing (again)Neil Brown2006-06-231-6/+6
| | | | | | | | | | | | | | | | Bruce Fields noticed that I broke comment parsing... as xskip() is always called before xgettok(), that is the best place to put xskipcomment and still maintain proper semantics of xskip and xgettok.
| * Try to make sure that clientid used for NFSv4 is reliable.Neil Brown2006-06-232-4/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | We need to give an IP address to identify this client to the server. The current code does a gethostbyname of the hostname. One some systems this returns 127.0.0.1 or similar, which is not useful. Instead, use getsockname of the sock used to connect to the server to confirm that the server is working. This gives the address on the interface that was chosen to talk to that server, which is the best address we can find (if there is a NAT in the way, it might still not work, but in that case there is nothing we can do).

* multiple threads for mountdGreg Banks2006-06-161-0/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. I don't speak for SGI.

Remove local copies of the gssapi and rpcsecgss header files. This depends on the configure_use_autotools patch.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | *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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * utils/exportfs/exports.man: Document the "crossmnt" export export option * utils/gssd/krb5_util.c: Add better debugging and partially revert the function check for gss_krb5_ccache_name. For MIT Kerberos releases up to and including 1.3.1, we *must* use the routine gss_krb5_ccache_name to get the K5 gssapi code to use a different credentials cache. For releases 1.3.2 and on, we want to use the KRB5CCNAME environment variable to tell it what to use. (A problem was reported where 1.3.5 was being used, our code was using gss_krb5_ccache_name, but the underlying code continued to use the first (or default?) credentials cache. Switching to using the env variable fixed the problem. I cannot recreate this problem. *utils/gssd/krb5_util.c: Andrew Mahone <andrew.mahone@gmail.com> reported that reiser4 always has DT_UNKNOWN. He supplied patch to move the check for regular files after the stat() call to correctly find ccache files in reiser4 filesystem. Also change the name comparison so that the wrong file is not selected when the substring comparison is done. *utils/gssd/krb5_util.c: Limit the set of encryption types that can be negotiated by the Kerberos library to those that the kernel code currently supports. This should eventually query the kernel for the list of supported enctypes. *utils/gssd/gss_util.c, utils/svcgssd/svcgssd_main_loop.c: Print more information in error messages to help debugging failures. *utils/svcgssd/svcgssd_proc.c: Increase token buffer size and update error handling so that a response is always sent. *utils/svcgssd/svcgssd_proc.c: Add support to retrieve supplementary groups.
