* [GFS2] Make journaled data files identical to normal files on diskSteven Whitehouse2006-02-0819-1477/+721
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a very large patch, with a few still to be resolved issues so you might want to check out the previous head of the tree since this is known to be unstable. Fixes for the various bugs will be forthcoming shortly. This patch removes the special data format which has been used up till now for journaled data files. Directories still retain the old format so that they will remain on disk compatible with earlier releases. As a result you can now do the following with journaled data files: 1) mmap them 2) export them over NFS 3) convert to/from normal files whenever you want to (the zero length restriction is gone) In addition the level at which GFS' locking is done has changed for all files (since they all now use the page cache) such that the locking is done at the page cache level rather than the level of the fs operations. This should mean that things like loopback mounts and other things which touch the page cache directly should now work. Current known issues: 1. There is a lock mode inversion problem related to the resource group hold function which needs to be resolved. 2. Any significant amount of I/O causes an oops with an offset of hex 320 (NULL pointer dereference) which appears to be related to a journaled data buffer appearing on a list where it shouldn't be. 3. Direct I/O writes are disabled for the time being (will reappear later) 4. There is probably a deadlock between the page lock and GFS' locks under certain combinations of mmap and fs operation I/O. 5. Issue relating to ref counting on internally used inodes causes a hang on umount (discovered before this patch, and not fixed by it) 6. One part of the directory metadata is different from GFS1 and will need to be resolved before next release. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
* [GFS2] Update truncate function (shrinking partial blocks)Steven Whitehouse2006-01-314-57/+63
| | | | | | | | | | Update the function in GFS2 which deals with truncation of partial blocks. Some of the code is "borrowed" from ext3 since it appears to give a good model of how to do this operation. The function is renamed gfs2_block_truncate_page accordingly.

* [GFS2] Add gfs2_internal_read()Steven Whitehouse2006-01-3012-149/+187
| | | | | | | | | | | | | | | | | Add the new external read function. Its temporarily in jdata.c even though the protoype is in ops_file.h - this will change shortly. The current implementation will change to a page cache one when that happens. In order to effect the above changes, the various internal inodes now have Linux inodes attached to them. We keep the references to the Linux inodes, rather than the gfs2_inodes in the super block. In order to get everything to work correctly I've had to reorder the init sequence on mount (which I should probably have done earlier when .gfs2_admin was made visible).

However, hmac code (crypto_hmac_final) assumes that the 'out' argument is in virtual memory (identity mapped region) and can use virt_to_page call on it. This does not work with the on-stack declared digest. The problems observed so far have been: a) incorrect hmac digest b) machine check and hardware reset. Solution is to define the digest in an identity mapped region by kmalloc'ing it. We can do this once as part of the endpoint structure and re-use it when verifying the SCTP cookie.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch corrects the panic by casting the argument to the pointer of correct size. On big-endian systems we ended up loading only 32 bits of data because we are treating the pointer as an int*. By treating this pointer as loff_t*, we'll load the full 64 bits and then let regular integer demotion take place which will give us the correct value.

| | | * [SCTP]: sctp doesn't show all associations/endpoints in /procVlad Yasevich2006-01-171-18/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When creating a very large number of associations (and endpoints), /proc/assocs and /proc/eps will not show all of them. As a result netstat will not show all of the either. This is particularly evident when creating 1000+ associations (or endpoints). As an example with 1500 tcp style associations over loopback, netstat showed 1420 on my system instead of 3000. The reason for this is that the seq_operations start method is invoked multiple times bacause of the amount of data that is provided. The start method always increments the position parameter and since we use the position as the hash bucket id, we end up skipping hash buckets. This patch corrects this situation and get's rid of the silly hash-1 decrement. Signed-off-by: Vlad Yasevich <vladislav.yasevich@hp.com> Signed-off-by: Sridhar Samudrala <sri@us.ibm.com>

The layout of the cookie prameter is this: |<----- Parameter Header --------------------|<--- Cookie DATA -------- ----------------------------------------------------------------------- | param type (16 bits) | param len (16 bits) | sig [32 bytes] | cookie.. ----------------------------------------------------------------------- The cookie data portion contains 64 bit values on 64 bit architechtures (timeval) that fall on a 32 bit alignment boundry when used as part of the on-wire format, but align correctly when used in internal structures.

This is most easily seen with an X application that uses sub-second select/poll timeout such as emacs. You hit a key and it takes a second or so before the app responds. The two ROUND_UP() calls upon entry are using {tv,ts}_sec where it should instead be using {tv_usec,ts_nsec}, which perfectly explains the observed incorrect behavior.
