* First batch of converting SCSI HBAs from setting saa_targets andmatthew2011-07-081-3/+3

* Fix the LBA offset calculation for the last block in a rebuild, if therejsing2011-07-071-7/+7
| | | | | | | | | is a partial block. Also correctly handle the case where there is no partial block. Whilst here remove a pointless variable. Issues spotted by and based on diffs from Piotr Durlej - thanks! ok marco@

* Cleanup the softraid boot probe code. Rename the rather poorly namedjsing2011-07-021-120/+120
| | | | | | | | | | | sr_metadata_list struct to sr_boot_chunk and use a sr_metadata struct rather than an array of u_int8_t when storing the metadata. Also rename some variables to keep the boot volume/boot chunk consistency. This diff also fixes a memory leak where the structures were never freed for key disks. Otherwise there should be no functional change. ok marco@

| | | | | | | | | scsibus(4) for all attached disks, rather than one scsibus(4) per disk. This takes advantage of recent improvements in the SCSI midlayer to better support hotplug devices, and also decouples softraid(4) from scsibus(4) device unit numbers. ok jsing@, dlg@, krw@, deraadt@; marco@'s still unconvinced

| | | | | | | | | | | logical block address, not the size of the device. Adjust softraid's handling of the commands accordingly. Fixes panics when newfs'ing the 'c' partition of a softraid volume (one shouldn't newfs 'c' partitions of any device). Reported by Andreas Bartlet via tech@. Fix tested by Andreas. ok marco@. functionally identical diff developed by dlg@
* Move raid1 and crypto io to a workq. This is to avoid a potential VOP_marco2010-11-061-5/+37
| | | | | | | | | call while in interrupt context. Contains an additional spl dance as found by thib. Tested by many opn various arches. Note that raid 0/4/5/6 have not been moved over yet.
* Force openings to 1 for devices that can't do tagged i/o, i.e. morekrw2010-10-121-1/+2
| | | | | | | | | | | | | | than 1 i/o active at once. This reduces the chances that concurrent i/o's for such devices will confuse the device or the adapter code. It also eliminates a reason for adapter code to maintain its own queues. Tweak all drivers that fake INQUIRY results to set the SID_CmdQue flag, thus continuing to claim to be able to do tagged i/o. Positive feedback from matthew@ and marco@ for an earlier version. ok dlg@
* The only sensible argument for VOP_* calls that take a struct proc pointer isoga2010-09-231-20/+25
| | | | | | | | | | | | | | | | | | curproc. A bunch of callers were passing in 0 (not even NULL, 0) as this pointer, which was fine until the called vnode function tried to do something with it. Typically, this code was then copy/pasted to various parts of the tree. Accept the facts of life and switch all of these over to passing curproc for now until the argument can be removed. Discovered by stsp trying to create a softraid on top of a vnd, which crashed with a NULL deref in vndioctl. softraid bits tested by mikeb and jsing. raidframe bits tested by pea, matthieu and naddy. The rest tested by at least thib, jsing and myself. ok thib@, jsing@.

| | | | | | | | | where disks can be on alldevs, however they are not yet initialised and have not yet called disk_attach() (in particular this means that dk_label is a null pointer). Also, if we sleep restart the scan from the top of the disklist in case things have changed whilst we slept. ok marco@

* Determine the data offset using a variable specified within the softraidjsing2010-07-021-9/+36

* Add storage for the boot block and boot loader to the softraid metadata.jsing2010-03-261-7/+4
| | | | | | | | | | | | | Also add a new optional metadata type for boot data. This is the first step (of many) towards being able to boot from softraid volumes. WARNING: This version of the softraid metadata is not compatible with previous versions. As a result, any softraid volumes created with older kernels will not assemble. Data on existing softraid volumes should be backed up before upgrading. The volume should then be recreated and the data restored. ok marco@
* Change the scsi_cmd function member of scsi_adapter from int tokrw2010-03-231-6/+8
| | | | | | | | | | | | | void. Use XS_NO_CCB error in the scsi command (xs) to report the NO_CCB condition. Eliminates all SUCCESSFULLY_QUEUED and COMPLETE confusion and untangles the midlayer from the adapter a bit more. Eyes and some fixes by miod@ There may be some compile issues on little used (i.e. I don't have any) drivers but the change is mechanical and thus easy to remedy. ok dlg@
