* (This commit touches about 15 disk device drivers in a very consistentPoul-Henning Kamp2002-09-201-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | and predictable way, and I apologize if I have gotten it wrong anywhere, getting prior review on a patch like this is not feasible, considering the number of people involved and hardware availability etc.) If struct disklabel is the messenger: kill the messenger. Inside struct disk we had a struct disklabel which disk drivers used to communicate certain metrics to the disklayer above (GEOM or the disk mini-layer). This commit changes this communication to use four explicit fields instead. Amongst the benefits is that the fields do not get overwritten by wrong or bogus on-disk disklabels. Once that is clear, <sys/disk.h> which is included in the drivers no longer need to pull <sys/disklabel.h> and <sys/diskslice.h> in, the few places that needs them, have gotten explicit #includes for them. The disklabel inside struct disk is now only for internal use in the disk mini-layer, so instead of embedding it, we malloc it as we need it. This concludes (modulus any mistakes) the series of disklabel related commits. I belive it all amounts to a NOP for all the rest of you :-) Sponsored by: DARPA & NAI Labs.

* For reasons now lost in historical fog, the bounds_check_with_label()Poul-Henning Kamp2002-09-201-0/+58

* Make FreeBSD "struct disklabel" agnostic, step 311 of 723:Poul-Henning Kamp2002-09-201-57/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Rename diskerr() to disk_err() for naming consistency. Drop the by now entirely useless struct disklabel argument. Add a flag argument for new-line termination. Fix a couple of printf-format-casts to %j instead of %l. Correctly print the name of all bio commands. Move the function from subr_disklabel.c to subr_disk.c, and from <sys/disklabel.h> to <sys/disk.h>. Use the new disk_err() throughout, #include <sys/disk.h> as needed. Bump __FreeBSD_version for the sake of the aac disk drivers #ifdefs. Remove unused disklabel members of softc for aac, amr and mlx, which seem to originally have been intended for diskerr() use, but which only rotted and got Copy&Pasted at least two times to many.

* This commit adds basic support for the UFS2 filesystem. The UFS2Kirk McKusick2002-06-211-5/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | filesystem expands the inode to 256 bytes to make space for 64-bit block pointers. It also adds a file-creation time field, an ability to use jumbo blocks per inode to allow extent like pointer density, and space for extended attributes (up to twice the filesystem block size worth of attributes, e.g., on a 16K filesystem, there is space for 32K of attributes). UFS2 fully supports and runs existing UFS1 filesystems. New filesystems built using newfs can be built in either UFS1 or UFS2 format using the -O option. In this commit UFS1 is the default format, so if you want to build UFS2 format filesystems, you must specify -O 2. This default will be changed to UFS2 when UFS2 proves itself to be stable. In this commit the boot code for reading UFS2 filesystems is not compiled (see /sys/boot/common/ufsread.c) as there is insufficient space in the boot block. Once the size of the boot block is increased, this code can be defined. Things to note: the definition of SBSIZE has changed to SBLOCKSIZE. The header file <ufs/ufs/dinode.h> must be included before <ufs/ffs/fs.h> so as to get the definitions of ufs2_daddr_t and ufs_lbn_t. Still TODO: Verify that the first level bootstraps work for all the architectures. Convert the utility ffsinfo to understand UFS2 and test growfs. Add support for the extended attribute storage. Update soft updates to ensure integrity of extended attribute storage. Switch the current extended attribute interfaces to use the extended attribute storage. Add the extent like functionality (framework is there, but is currently never used). Sponsored by: DARPA & NAI Labs.

* Comment out Kirks io-request priority hack until we can do this in aPoul-Henning Kamp2002-04-221-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | civilized way which doesn't cause grief. The problem is that it is not generally safe to cast a "struct bio *" to a "struct buf *". Things like ccd, vinum, ata-raid and GEOM constructs bio's which are not entrails of a struct buf. Also, curthread may or may not have anything to do with the I/O request at hand. The correct solution can either be to tag struct bio's with a priority derived from the requesting threads nice and have disksort act on this field, this wouldn't address the "silly-seek syndrome" where two equal processes bang the diskheads from one edge to the other of the disk repeatedly. Alternatively, and probably better: a sleep should be introduced either at the time the I/O is requested or at the time it is completed where we can be sure to sleep in the right thread. The sleep also needs to be in constant timeunits, 1/hz can be practicaly any sub-second size, at high HZ the current code practically doesn't do anything. Notes: svn path=/head/; revision=95246

* Fixed handling of short reads in readdisklabel() and writedisklabel().Bruce Evans2002-03-301-0/+6
| | | | | | | | | | | | | | | | | | | These functions use DEV_STRATEGY() which can easily return a short count (with no error) for reads near EOF. EOF happens for "disks" too small to contain a label sector (mainly for empty slices). The functions didn't understand this at all, and looked for labels in the garbage in the buffer beyond what DEV_STRATEGY() returned. The recent UMA changes combined with my local changes and configuration resulted in the garbage often containing a valid but garbage label left over from a previous call. Bugs in EOF handling in -current limited the problem to "disks" with size precisely LABELSECTOR sectors. LABELSECTOR happens to be a very unusual "disk" size since it is only 0 for non-i386 arches that don't usually have disks with DOS MBRs. Notes: svn path=/head/; revision=93431

| | | | | | | | | | | | | | | | | | | | | | | | field in struct buf: b_iocmd. The b_iocmd is enforced to have exactly one bit set. B_WRITE was bogusly defined as zero giving rise to obvious coding mistakes. Also eliminate the redundant struct buf flag B_CALL, it can just as efficiently be done by comparing b_iodone to NULL. Should you get a panic or drop into the debugger, complaining about "b_iocmd", don't continue. It is likely to write on your disk where it should have been reading. This change is a step in the direction towards a stackable BIO capability. A lot of this patch were machine generated (Thanks to style(9) compliance!)

* Use only the correct raw partition for writing labels. Don't use theBruce Evans1998-10-171-9/+4
| | | | | | | | | | | | | | | | | | | | | | | | partition that the label ioctl is being done on just because it has offset 0, since there is no guarantee that such a partition is large enough to contain the label. Don't use the wrong raw partition (0 instead of RAW_PART). This fixes problems rewriting bizarre labels (with a nonzero offset for the 'a' partition) in newfs(8). Such labels shouldn't normally be used, but creating them was allowed if the ioctl was done on the raw partition, and sysinstall creates them if the root partition isn't allocated first. Note that allowing write access to a partition other than the one that has been checked for write access doesn't increase security holes significantly, since write access to any partition already allows changing the in-core label. This fix should be in 3.0R. Rev.1.26 of newfs/newfs.c shouldn't be in 3.0R. Notes: svn path=/head/; revision=40469
