* Improve first attempt at acquiring GSS credentialsSimo Sorce2014-01-171-22/+2
| | | | | | | | | | | | | | Since now rpc.gssd is swithing uid before attempting to acquire credentials, we do not need to pass in the special uid-as-a-string name to gssapi, because the process is already running under the user's credentials. By removing this code we can fix a class of false negatives where the user name does not match the actual ccache credentials and the ccache type used is not one of the only 2 supported explicitly by rpc.gssd by the fallback trolling done later.

| | | | | | | | | | | | | | | | | | | | From: "J. Bruce Fields" <bfields@redhat.com> By unconditionally adding ?4.2 to the version string written to the kernel we make nfs-utils incompatible with pre-4.2-supporting kernels. Ditto for 4.1. This problem was introduced by 12a590f8d556c00a9502eeebaa763d906222d521 "rpc.nfsd: Allow v4.2 server support with the -V option", which also change nfsd to unconditionally pass ?4.2. Instead, just don't mention 4.1 or 4.2 unless the commandline has specifically requested that one or the other be turned on or off.

| | | | | | | | | | | | | I was reminded recently that NFS treats file atime time stamps differently than other filesystems.

* gssd: don't let parent exit until child has a chance to scan directory onceJeff Layton2013-11-203-2/+9
| | | | | | | | | | | | | With some proposed kernel changes, it won't even attempt to upcall sometimes if it doesn't appear that gssd is running. This means that we have a theoretical race between gssd starting up at boot time and the init process attempting to mount kerberized filesystems. Fix this by switching gssd to use mydaemon() and having the child only release the parent after it has processed the directory once.

* nfs-utils: consolidate mydaemon() and release_parent() implementationsJeff Layton2013-11-205-167/+159
| | | | | | | | | | | | | | | | | | | | | | | | | | We currently have 2 cut-and-paste versions of this code. One for idmapd and one for svcgssd.[1] The two are basically equivalent but there are some small differences, mostly related to how errors in that function are logged. svcgssd uses printerr() with a priority of 1, which only prints errors if -v was specified. That doesn't seem to be quite right. Daemonizing errors are necessarily fatal and should be logged as such. The one for idmapd uses err(), which always prints to stderr even though we have the xlog facility set up. Since both have xlog configured at this point, log the errors using xlog_err() instead. The only other significant difference I see is that the idmapd version will open "/" if it's unable to open "/dev/null". I believe that however was a holdover from an earlier version of that function that did not error out when we were unable to open a file descriptor. Since the function does that now, I don't believe we need that fallback anymore. [1]: technically, we have a third in statd too, but it's different enough that I don't want to touch it here.

* gssd: don't let spurious signals interrupt the wait after forkingJeff Layton2013-11-201-1/+4
| | | | | | | | | | | | Because gssd uses dnotify under the hood, it's easily possible that the parent process can catch a signal while processing an upcall. If that happens, then we'll currently exit the wait for the child task to exit, and it'll end up as a zombie. Fix this by ensuring that we only wait for the child to actually exit.

* mount.nfs: Recognize v4.x mount optionsWeston Andros Adamson2013-11-201-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The kernel understands text options of the form "v4.x" (ie "v4.1"), but mount.nfs does not and this leads to weird errors when the requested mount fails: a line in dmesg about version 3 not supporting minorversions and mount.nfs returning EINVAL no matter what the real error was. This happens because mount.nfs thinks no version was specified so it starts probing other versions which conflicts with the v4.X option once it gets parsed by the kernel. $ sudo mount -v -o v4.1 zero:/invalid_export /mnt mount.nfs: timeout set for Wed Nov 13 10:09:48 2013 mount.nfs: trying text-based options 'v4.1,vers=4,addr=192.168.100.10,clientaddr=192.168.100.11' mount.nfs: mount(2): No such file or directory mount.nfs: trying text-based options 'v4.1,addr=192.168.100.10' mount.nfs: prog 100003, trying vers=3, prot=6 mount.nfs: trying 192.168.100.10 prog 100003 vers 3 prot TCP port 2049 mount.nfs: prog 100005, trying vers=3, prot=17 mount.nfs: trying 192.168.100.10 prog 100005 vers 3 prot UDP port 20048 mount.nfs: mount(2): Invalid argument mount.nfs: an incorrect mount option was specified And you get this in dmesg: NFS: mount option vers=3 does not support minorversion=1 but if you use another form of the same options, this doesn't happen: $ sudo mount -v -o vers=4,minorversion=1 zero:/invalid_export /mnt mount.nfs: timeout set for Wed Nov 13 10:10:28 2013 mount.nfs: trying text-based options 'vers=4,minorversion=1,addr=192.168.100.10,clientaddr=192.168.100.11' mount.nfs: mount(2): No such file or directory mount.nfs: mounting zero:/invalid_export failed, reason given by server: No such file or directory Acked-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: Weston Andros Adamson <dros@netapp.com> Signed-off-by: Steve Dickson <steved@redhat.com>
* gssd: Fix file descriptor leak of old pipe dirsWeston Andros Adamson2013-11-202-1/+6
| | | | | | | | | | | | | | | | | | gssd doesn't properly clean up internal state for old pipes and never closes the (since deleted) clnt_info directory. This leads to eventual fd exhaustion. To reproduce, run a lot of mount / umounts in a loop and watch the output of 'ls /proc/$PID/fdinfo | wc -l' (where PID is the pid of gssd) steadily grow until gssd eventually crashes with "Too many open files". This regression was introduced by 841e83c1, which was trying to fix a similar bug in the skip matching logic of update_old_clients. The problem with that patch is that pdir will never match dirname, because dirname is "<pname>/clntXXX".

* gssd: always reply to rpc-pipe requests from kernel.NeilBrown2013-11-201-9/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Sometimes gssd will open a new rpc-pipe but never read requests from it or reply to them. This causes the kernel to wait forever for a reply. In particular, if a filesystem is mounted by IP, and the IP has no hostname recorded in /etc/hosts or DNS, then gssd will not listen to requests and the mount will hang indefinitely. The comment in process_clnt_dir() for the "fail_keep_client:" branch suggests that it is for the case where we couldn't open some subdirectories. However it is currently also taken if reverse DNS lookup fails (as well as some other lookup failures). Those failures should not be treated the same as failure-to-open directories. So this patch causes a failure from read_service_info() to *not* be reported by process_clnt_dir_files. This ensures that insert_clnt_poll() will be called and requests will be handled. In handle_gssd_upcall, the current error path (taken when the mech is not "krb5") does not reply to the upcall. This is wrong. A reply is always appropriate. The only replies which aren't treated as transient errors are EACCES and EKEYEXPIRED, so we return the former. If read_service_info() fails then ->servicename will be NULL which will cause process_krb5_upcall() (quite reasonably) to become confused. So in that case we don't even try to process the up-call but just reply with EACCES. As clp->servicename==NULL is no longer treated as fatal, it is not appropraite to use it to test if read_service_info() has been already called on a client. Instread test clp->prog. Finally, the error path of read_service_info() will close 'fd' if it isn't -1, so when we close it, we should set fd to -1.

* statd: fix race condition for parallel startup of statdRobert Schiele2013-11-051-2/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | When start_statd figures out that statd is not yet running it starts it, waits for the invoked process to complete, and finally verifies that statd is working. This approach works for serially mounting NFS file systems but has a race condition for parallel mounting. In the parallel case it can happen that two mount commands A and B both decide that statd needs to be started. Both of them try to start statd. Obviously only one of them can successfully do so, let's assume this is command A in our case. The statd invoked by B terminates because the resource is already claimed by the statd invoked by A. The termination of B's statd though is before the statd of A has completely set up all things. This causes the check for a working statd of command B to fail and terminate the mount request with an error. To prevent this we define a timeout value. In case the initial check after invoking statd fails we try again in a loop 10 times a second until the timeout is reached. In our tests when the race occurred we typically were successful already on the first retry within the loop. Signed-off-by: Steve Dickson <steved@redhat.com>

* gssd: validate cred in gssd_acquire_user_credWeston Andros Adamson2013-10-281-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | Call gss_inquire_cred after gssd_acquire_krb5_cred check for expired credentials.

* gssd: do a more thorough change of identity after forkingJeff Layton2013-10-211-16/+66
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The part of process_krb5_upcall that handles non-machine user creds first tries to query GSSAPI for credentials. If that fails, it then falls back to trawling through likely credcache locations to find them and then points $KRB5CCNAME at it before proceeding. There are a number of bugs in this code that this patch attempts to address. The code that queries GSSAPI for credentials does it as root which almost universally fails to do anything useful unless we happen to be looking for non-machine root creds. Because of this, gssd almost always falls back to having to search for credcaches "manually". The code that handles credential switching is in create_auth_rpc_client, so it's too late to be of any use here. Worse yet, for historical reasons the MIT krb5 authors used %{uid} in the default credcache locations which translates to the real uid. Thus switching the fsuid or even euid is insufficient. You must switch the real uid in order to be able to find the proper credcache in most cases. This patch moves the credential switching to occur much earlier in the process and has it do a much more thorough job of it. It first drops all supplimentary groups, then determines a gid to use and switches the gids and uids to the correct ones. If it can't determine the correct gid to use, it then tries to look up the one for "nobody" and uses that. Once the credentials are switched, the forked child now no longer tries to change them back. It does the downcall with the new credentials and just exits when it's done. Signed-off-by: Jeff Layton <jlayton@redhat.com> Signed-off-by: Steve Dickson <steved@redhat.com>
* gssd: have process_krb5_upcall fork before handling upcallJeff Layton2013-10-211-1/+23
| | | | | | | | | | | | | | | | | | | Most krb5 installations use credcache locations that contain %{uid}, which expands to the real UID of the current process. In order for GSSAPI to find those properly, we need to be able to switch the real UID of the process to the designated one. That however, opens the door to allowing gssd to be killed or reniced during the window where we've switched credentials. To combat this, change gssd to fork before trying to handle each upcall. The child will do the work to establish the context and the parent task will just wait for it to exit. It's still possible for the child to be killed or reniced, but that would only affect a single upcall instead of the entire daemon. Also, If the process is killed prematurely, then log an error to tip off the admin that there was a problem.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 11ba3b1e01b67b7d19f26fba94fabdb60878e809 (Add a default flavor to an export's e_secinfo list) breaks the ordering of security flavours in the secinfo list, by reordering 'sec=sys' to always be the first secinfo flavour if one fails to set a default 'sec' setting. An export of the form: /export -sync,no_subtree_check,mp \ 192.168.1.0/24(sec=krb5p:krb5i:krb5,rw,sec=sys,ro) ends up getting translated by exportfs into the following entry in /var/lib/nfs/etab: /export 192.168.1.0/24(ro,sync,wdelay,hide,nocrossmnt,\ secure,root_squash,no_all_squash,\ no_subtree_check,secure_locks,acl,\ mountpoint,anonuid=65534,anongid=65534,\ sec=sys,ro,root_squash,no_all_squash,\ sec=krb5p:krb5i:krb5,rw,root_squash,no_all_squash) Note how the 'sec=sys' is now listed first... The fix is to defer adding the default flavour until the call to secinfo_show, when we can see if it is even needed at all. With the patch, the above export is now correctly entered in /var/lib/nfs/etab as: /export 192.168.1.0/24(ro,sync,wdelay,hide,nocrossmnt,\ secure,root_squash,no_all_squash,\ no_subtree_check,secure_locks,acl,\ mountpoint,anonuid=65534,anongid=65534,\ sec=krb5p:krb5i:krb5,rw,root_squash,no_all_squash,\ sec=sys,ro,root_squash,no_all_squash) Cc: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com> Signed-off-by: Steve Dickson <steved@redhat.com>
* gssd: don't use tgtname to find our keytabJ. Bruce Fields2013-09-241-6/+9
| | | | | | | | | | | | | | | | From: "J. Bruce Fields" <bfields@redhat.com> The tgtname is of the form service@hostname. It's not a hostname, and attempting to look it up here just causes failure of any upcall with a "target=" field (currently, any upcall on behalf of an nfsv4.0 callback). I think the theory was that knowning that target= name might help pick the right keytab, but I don't really know if that's helpful. For now, just stop trying to do this. Signed-off-by: J.

* gssd: fix strncmp bug causing client removalsJ. Bruce Fields2013-09-241-1/+1
| | | | | | | | | | | | | | | | From: "J. Bruce Fields" <bfields@redhat.com> Both dirname and pdir are null-terminated strings, so there's no reason I can see for the strncmp. And this gives the wrong result when comparing the "nfsd" and "nfsd4_cb" directories! The results were callback clients being removed immediately after creation, when lack of a client with the corresponding name under "nfsd" lead gssd to believe it had disappeared from "nfsd4_cb".

* exportfs: insecure/secure should be a secinfo_flagTrond Myklebust2013-09-181-7/+27
| | | | | | | | | | | | | The 'insecure' flag is listed in /proc/fs/nfsd/export_features in newer kernels as being a secinfo_flag, however it is not displayed by secinfo_show. This patch fixes that, and sets up a framework which should make it easy to add new flags to /proc/fs/nfsd/export_features and have them be displayed properly.

* gssd: suppress error message if rpc_pipefs dir disappears.NeilBrown2013-09-051-2/+3
| | | | | | | | | | | | | | | | | | | | It is possible for a race to cause a name to appear when an rpc_pipefs dir is scanned but to no longer be present when we try to open it. So if the error is ENOENT, don't complain. This is similar to commit 5ac9bcfd820f09af4d3f87f1f7346d896f70bc9a Author: David Jeffery <djeffery@redhat.com> Date: Wed Jan 16 15:21:55 2013 -0500 rpc.idmapd: Ignore open failures in dirscancb() which addressed a similar issue in idmapd.
