* Get Vinum up and running with GEOM:Robert Watson2002-10-051-86/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | (1) Use namei() and devfs to discover devices rather than a hard-coded MAKEDEV implementation. Once rootfs is in place, this will allow Vinum to be used for the root file system partition. (2) Pass FREAD to device opens so that GEOM will return sector size rather than an error on attempts to read label data. (3) Avoid clobbering return values from close_drive() and masking this failure, resulting in a later divide by zero due to not having updated the Vinum-cached sector size. (4) Ignore failures from DIOCWLABEL as that appears not to be required in the GEOM environment. We've done testing in simple Vinum environments, but those with more complex environments might want to give this a spin in DP2 and make sure everything is up to speed.

* Change the suser() API to take advantage of td_ucred as well as do aJohn Baldwin2002-04-011-1/+1
| | | | | | | | | | | | | | | general cleanup of the API. The entire API now consists of two functions similar to the pre-KSE API. The suser() function takes a thread pointer as its only argument. The td_ucred member of this thread must be valid so the only valid thread pointers are curthread and a few kernel threads such as thread0. The suser_cred() function takes a pointer to a struct ucred as its first argument and an integer flag as its second argument. The flag is currently only used for the PRISON_ROOT flag.

* Introduce the new 64-bit size disk block, daddr64_t. ChangeKirk McKusick2002-03-154-12/+12
| | | | | | | | | | | | | | | the bio and buffer structures to have daddr64_t bio_pblkno, b_blkno, and b_lblkno fields which allows access to disks larger than a Terabyte in size. This change also requires that the VOP_BMAP vnode operation accept and return daddr64_t blocks. This delta should not affect system operation in any way. It merely sets up the necessary interfaces to allow the development of disk drivers that work with these larger disk block addresses. It also allows for the development of UFS2 which will use 64-bit block addresses. Notes: svn path=/head/; revision=92363

* Add a field 'version' to vinum_conf. This field is a constant whichGreg Lehey2001-05-221-191/+30
| | | | | | | | | | | | | | | | gets incremented every time the kernel-userland interface changes. This enables vinum(8) to check for the correct kernel version and to produce a useful message if it doesn't match. Requested by: Too many to count. Move the definitions of struct drive, sd, plex and volume to vinumobj.h. Add a new debug flag, DEBUG_LOCKREQS, which logs only lock requests. Notes: svn path=/head/; revision=76964
* vinumstart: If a write request is for a RAID-[45] plex or a volumeGreg Lehey2001-05-221-13/+23
| | | | | | | | | | | | | | | | | | | | with more than one plex, the data will be accessed multiple times. During this time, userland code could potentially modify the buffer, thus causing data corruption. In the case of a multi-plexed volume this might be cosmetic, but in the case of a RAID-[45] plex it can cause severe data corruption which only becomes evident after a drive failure. Avoid this situation by making a copy of the data buffer before using it. Note that this solution does not guarantee any particular content of the buffer, just that it remains unchanged for the duration of the request.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Use this instead of DEBUG_LASTREQS to decide whether to log lock requests. MFS: vinumlock: Catch a potential race condition where one process is waiting for a lock, and between the time it is woken and it retries the lock, another process gets it and places it in the first entry in the table. This problem has not been observed, but it's possible, and it's easy enough to fix. Submitted by: tegge vinumunlock: Catch a real bug capable of hanging a system. When releasing a lock, vinumunlock() called wakeup_one. This caused wakeups to sometimes get lost. After due consideration, we think that this is due to the fact that you can't guarantee that some other process is also waiting on the same address. This makes wakeup_one a very dangerous function to use. Notes: svn path=/head/; revision=76960
