cam_get_device: resolve path links before parsing device name

2022-02-16T07:52:53Z

The CAM subsystem uses bus:taget:lun tuple to address peripherals. But for convenience many userland programs such as camcontrol accept devices names such as da0. There is a libcam function, cam_open_device, to support that. It first calls cam_get_device() to parse the device name as a driver name and a unit (and handle some special device name prefixes) and then uses cam_lookup_pass() to find a matching pass device. This change extends cam_get_device() to apply realpath(3) to the device name before parsing it. This will allow to use tools such as camcontrol and smartctl with symbolic links that could be friendlier (more distinguished) names for devices. Relnotes: maybe (cherry picked from commit 1abf1e8c6b13f50eed08fef6fb1ade280894f1e4)

libcam(3): make cam_getccb(3) zero the whole ccb, not just the header

2020-12-29T14:26:06Z

Leaving zeroing to the clients leads to error-prone pointer tricks (zeroing needs to preserve the CCB header), and this code is not performance-critical, so there's really no reason to not do it.

Do a sweep and remove most WARNS=6 settings

2020-10-01T01:10:51Z

Repeating the default WARNS here makes it slightly more difficult to experiment with default WARNS changes, e.g. if we did something absolutely bananas and introduced a WARNS=7 and wanted to try lifting the default to that. Drop most of them; there is one in the blake2 kernel module, but I suspect it should be dropped -- the default WARNS in the rest of the build doesn't currently apply to kernel modules, and I haven't put too much thought into whether it makes sense to make it so.

Remove unused cam ccb flags

2020-03-10T23:58:41Z

These flags have been unused for some time. Some of them were in the CAM2 specification, but CAM has moved on a bit from that. Some were used in the old Pluto VideoSpace (and AirSpace) systems which had the video playback I/O scheduler in userspace, but have been unused since then.
