This patch fixes bug 243131: Can't mount GFS2 file system on AoE device. When using AoE devices with lock_nolock, there is no locking table, so gfs2 (and gfs1) uses the superblock s_id. This turns out to be the device name in some cases. In the case of AoE, the device contains a slash, (e.g. "etherd/e1.1p2") which is an invalid character when we try to register the table in sysfs. This patch replaces the "/" with underscore. Rather than add a new variable to the stack, I'm just reusing a (char *) variable that's no longer used: table. This code has been tested on the failing system using a RHEL5 patch. The upstream code was tested by using gfs2_tool sb to interject a "/" into the table name of a clustered gfs2 file system.

This fixes a bug in the ordering of operations in the error path of createi. Its not valid to do an iput() when holding the inode's glock since the iput() will (in this case) result in delete_inode() being called which needs to grab the lock itself. This was causing the recursive lock checking code to trigger. Signed-off-by: NSteven Whitehouse <swhiteho@redhat.com>

This adds a nanosecond timestamp feature to the GFS2 filesystem. Due to the way that the on-disk format works, older filesystems will just appear to have this field set to zero. When mounted by an older version of GFS2, the filesystem will simply ignore the extra fields so that it will again appear to have whole second resolution, so that its trivially backward compatible.

This patch fixes some sign issues which were accidentally introduced into the quota & statfs code during the endianess annotation process. Also included is a general clean up which moves all of the _host structures out of gfs2_ondisk.h (where they should not have been to start with) and into the places where they are actually used (often only one place). Also those _host structures which are not required any more are removed entirely (which is the eventual plan for all of them). The conversion routines from ondisk.c are also moved into the places where they are actually used, which for almost every one, was just one single place, so all those are now static functions. This also cleans up the end of gfs2_ondisk.h which no longer needs the #ifdef __KERNEL__. The net result is a reduction of about 100 lines of code, many functions now marked static plus the bug fixes as mentioned above. For good measure I ran the code through sparse after making these changes to check that there are no warnings generated.

This is a patch for the first three issues of RHBZ #238162 The first issue is that when you allocate a new page for a file, it will not start off uptodate. This makes sense, since you haven't written anything to that part of the file yet. Unfortunately, gfs2_pin() checks to make sure that the buffers are uptodate. The solution to this is to mark the buffers uptodate in gfs2_commit_write(), after they have been zeroed out and have the data written into them. I'm pretty confident with this fix, although it's not completely obvious that there is no problem with marking the buffers uptodate here. The second issue is simply that you can try to pin a data buffer that is already on the incore log, and thus, already pinned. This patch checks to see if this buffer is already on the log, and exits databuf_lo_add() if it is, just like buf_lo_add() does. The third issue is that gfs2_log_flush() doesn't do it's block accounting correctly. Both metadata and journaled data are logged, but gfs2_log_flush() only compares the number of metadata blocks with the number of blocks to commit to the ondisk journal. This patch also counts the journaled data blocks. Signed-off-by: NBenjamin Marzinski <bmarzins@redhat.com> Signed-off-by: NSteven Whitehouse <swhiteho@redhat.com>

Change the user/kernel device interface used by libdlm: - Add ability for userspace to check the version of the interface. libdlm can now adapt to different versions of the kernel interface. - Increase the size of the flags passed in a lock request so all possible flags can be used from userspace. - Add an opaque "xid" value for each lock. This "transaction id" will be used later to associate locks with each other during deadlock detection. - Add a "timeout" value for each lock. This is used along with the DLM_LKF_TIMEOUT flag. Also, remove a fragment of unused code in device_read(). This patch requires updating libdlm which is backward compatible with older kernels.

New features: lock timeouts and time warnings. If the DLM_LKF_TIMEOUT flag is set, then the request/conversion will be canceled after waiting the specified number of centiseconds (specified per lock). This feature is only available for locks requested through libdlm (can be enabled for kernel dlm users if there's a use for it.) If the new DLM_LSFL_TIMEWARN flag is set when creating the lockspace, then a warning message will be sent to userspace (using genetlink) after a request/conversion has been waiting for a given number of centiseconds (configurable per node). The time warnings will be used in the future to do deadlock detection in userspace. Signed-off-by: NDavid Teigland <teigland@redhat.com> Signed-off-by: NSteven Whitehouse <swhiteho@redhat.com>

This patch cleans up the inode number handling code. The main difference is that instead of looking up the inodes using a struct gfs2_inum_host we now use just the no_addr member of this structure. The tests relating to no_formal_ino can then be done by the calling code. This has advantages in that we want to do different things in different code paths if the no_formal_ino doesn't match. In the NFS patch we want to return -ESTALE, but in the ->lookup() path, its a bug in the fs if the no_formal_ino doesn't match and thus we can withdraw in this case. In order to later fix bz #201012, we need to be able to look up an inode without knowing no_formal_ino, as the only information that is known to us is the on-disk location of the inode in question. This patch will also help us to fix bz #236099 at a later date by cleaning up a lot of the code in that area. There are no user visible changes as a result of this patch and there are no changes to the on-disk format either. Signed-off-by: NSteven Whitehouse <swhiteho@redhat.com>

This patch removes the completion (which is rather large) from struct gdlm_lock in favour of using the wait_on_bit() functions. We don't need to add any extra fields to the structure to do this, so we save 32 bytes (on x86_64) per structure. This adds up to quite a lot when we may potentially have millions of these lock structures, Signed-off-by: NSteven Whitehouse <swhiteho@redhat.com> Acked-by: NDavid Teigland <teigland@redhat.com>

This addendum patch 2 corrects three things: 1. It fixes a stupid mistake in the previous addendum that broke gfs2. Ref: https://www.redhat.com/archives/cluster-devel/2007-May/msg00162.html 2. It fixes a problem that Dave Teigland pointed out regarding the external declarations in ops_address.h being in the wrong place. 3. It recasts a couple more %llu printks to (unsigned long long) as requested by Steve Whitehouse. I would have loved to put this all in one revised patch, but there was a rush to get some patches for RHEL5. Therefore, the previous patches were applied to the git tree "as is" and therefore, I'm posting another addendum. Sorry.

To avoid code redundancy, I separated out the operational "guts" into a new function called read_rindex_entry. Then I made two functions: the closer-to-original gfs2_ri_update (without the special condition checks) and gfs2_ri_update_special that's designed with that condition in mind. (I don't like the name, but if you have a suggestion, I'm all ears). Oh, and there's an added benefit: we don't need all the ugly gotos anymore. ;) This patch has been tested with gfs2_fsck_hellfire (which runs for three and a half hours, btw).

This is another revision of my gfs2 kernel patch that allows gfs2_grow to function properly. Steve Whitehouse expressed some concerns about the previous patch and I restructured it based on his comments. The previous patch was doing the statfs_change at file close time, under its own transaction. The current patch does the statfs_change inside the gfs2_commit_write function, which keeps it under the umbrella of the inode transaction. I can't call ri_update to re-read the rindex file during the transaction because the transaction may have outstanding unwritten buffers attached to the rgrps that would be otherwise blown away. So instead, I created a new function, gfs2_ri_total, that will re-read the rindex file just to total the file system space for the sake of the statfs_change. The ri_update will happen later, when gfs2 realizes the version number has changed, as it happened before my patch. Since the statfs_change is happening at write_commit time and there may be multiple writes to the rindex file for one grow operation. So one consequence of this restructuring is that instead of getting one kernel message to indicate the change, you may see several. For example, before when you did a gfs2_grow, you'd get a single message like: GFS2: File system extended by 247876 blocks (968MB) Now you get something like: GFS2: File system extended by 207896 blocks (812MB) GFS2: File system extended by 39980 blocks (156MB) This version has also been successfully run against the hours-long "gfs2_fsck_hellfire" test that does several gfs2_grow and gfs2_fsck while interjecting file system damage. It does this repeatedly under a variety Resource Group conditions. Signed-off-By: NBob Peterson <rpeterso@redhat.com> Signed-off-by: NSteven Whitehouse <swhiteho@redhat.com>

Fix for bz #231910 When filemap_fdatawrite() is called on the inode mapping in data=ordered mode, it will add the glock to the log. In inode_go_sync(), if you do the gfs2_log_flush() before this, after the filemap_fdatawrite() call, the glock and its associated data buffers will be on the log again. This means you can demote a lock from exclusive, without having it flushed from the log. The attached patch simply moves the gfs2_log_flush up to after the filemap_fdatawrite() call. Originally, I tried moving the gfs2_log_flush to after gfs2_meta_sync(), but that caused me to trip the following assert. GFS2: fsid=cypher-36:test.0: fatal: assertion "!buffer_busy(bh)" failed GFS2: fsid=cypher-36:test.0: function = gfs2_ail_empty_gl, file = fs/gfs2/glops.c, line = 61 It appears that gfs2_log_flush() puts some of the glocks buffers in the busy state and the filemap_fdatawrite() call is necessary to flush them. This makes me worry slightly that a related problem could happen because of moving the gfs2_log_flush() after the initial filemap_fdatawrite(), but I assume that gfs2_ail_empty_gl() would catch that case as well.
