Rename SID_INQUIRY_HDR (a.k.a. 5) to more explicit SID_SCSI2_HDRLEN and use it to replace various uses of '5' when calculating the amount of data in the INQUIRY response. Matches up more naturally with SID_SCSI2_ALEN. Also use to fix SCSIDEBUG display of INQUIRY responses to show correct count of bytes received/available.

massage the preferred path detection to happen when mpath asks for a paths status, rather than on attach. the status it returns depends on the type of device you have. hds provides two types of arrays, symmetric and asymmetric. on a symmetric device you can shove io down any path to any port on any controller and it will work. on symmetric devices we say all paths are part of the same group, and unconditionally return active path status to any check request. on asymmetric devices we group paths by which controller in teh array they connect to. the controllers return whether theyre providing a preferred path via a couple of status bits in a hds specific vpd page, so we query that and return the state of the bits. unfortunately hds arrays dont report change of lun ownership in any way, so we dont currently have any way of failing over at the moment. ill have to think about the least worst way to handle that. tested by deraadt@ on hppa

Add a DVACT_WAKEUP op to the *_activate() API. This is called after the kernel resumes normal (non-cold, able to run processes, etc) operation. Previously we were relying on specific DVACT_RESUME op's in drivers creating callback/threads themselves, but that has become too common, indicating the need for a built-in mechanism. ok dlg kettenis, tested by a sufficient amount of people

make path driver match routes return 8 so they will definitely be higher than the real device drivers. ses returns 3 on some dells, which could be confusing for autoconf if it has to decide between that and a path driver.

get rid of the different path scheduler types, which simplifies the code that picks the next path. we assume roundrobin within a group of paths now. the asym sym(4) devices work around this by putting every path in its own group.

when i first imagined how paths on mpath worked, i thought the midlayer would be able to call things on paths to explicitely online or offline them. turns out thats not how the Real World(tm) works, instead its better to wait for failure and probe for the status of paths, and pick the active group of paths from that. there's even evidence that the mechanisms for forcing controllers into active/passive roles from the scsi initiator are being deprecated. they expect hosts to be able to cope with arbitrary controller role changes and failover accordingly. this replaces the online and offline function pointers in the path_ops structure with a status check function pointer. instead of returning a state, the checker is expected to call mpath_path_status() when its finished figuring out what the state is.

checksense handlers in path drivers can return MPATH_SENSE_DECLINED (who can tell ive spent time in web servers) to say they decline interpreting the sense data, or MPATH_SENSE_FAILOVER to say the sense data is from the controller saying its failed over. all path drivers currently decline handling sense data.

introduce the idea of groups of paths. mpath had stuff to managed devices and paths. devices are what mpath presents as targets on its scsibus, and paths are the things attached to hardware controllers that are available to shove io down to the actual real target. all paths were considered usable for handling io on behalf of a device. this adds groups in between devices and paths. only paths on the first group in the list will now be used to handle io now. sym devices will only have one group. asym devices will treat each path as a different group. rdac, emc, and hds will group paths based on which controller in the array theyre connected to. in the future we will intercept sense data from passive controllers and use that to start running checks to pick a new primary group so we can handle controller failover situations. the group id in hds(4) is currently busted, everything else should be correct.

support "failover" style access to volumes, ie, only use one active path when talking to an array until it goes away, then you fail over to the next active path. im using this to talk to ses(4) in my dell, and allows us to support arrays that have multiple controllers but have no way of reporting which one is active. using the MRU semantic means we can talk to them without them flipping the active role between its controllers all the time. claudios transtec iscsi box is like this.
