* - Be more verbose when saying "foo" not found.delphij2007-03-301-10/+10
| | | | | | | - In gctl_get_geom(), don't issue error when we were not provided with an parameter, like gctl_get_provider() did. Reviewed by: pjd
* Change gctl_set_param() to return an error instead of setting anmarcel2006-04-071-12/+28
| | | | | | | | | | | error on the request. Add a wrapper, gctl_set_param_err(), that sets the error on the request from the error returned by gctl_set_param() and update current callers of gctl_set_param() to call gctl_set_param_err() instead. This makes gctl_set_param() much more usable in situations where the caller knows better what to do with certain (apparent) error conditions and setting an error on the request is not one of the things that need to be done.
* o Don't cause a panic when the control request lacks a verb.marcel2005-09-181-5/+9
| | | | | o Don't set the error twice when the named class does not exist. It causes ioctl(2) to return with error EEXIST.

* Device megapatch 4/6:phk2004-02-211-0/+2
| | | | | | | | Introduce d_version field in struct cdevsw, this must always be initialized to D_VERSION. Flip sense of D_NOGIANT flag to D_NEEDGIANT, this involves removing four D_NOGIANT flags and adding 145 D_NEEDGIANT flags.
* The present defaults for the open and close for device drivers whichphk2003-09-271-2/+0
| | | | | | | | | | | | | | provide no methods does not make any sense, and is not used by any driver. It is a pretty hard to come up with even a theoretical concept of a device driver which would always fail open and close with ENODEV. Change the defaults to be nullopen() and nullclose() which simply does nothing. Remove explicit initializations to these from the drivers which already used them.
* Only dump 512 bytes of debugging.phk2003-07-021-1/+2

* Run a revision on the OAM api.phk2003-03-271-53/+255
| | | | | | | Use prefix gctl_ systematically. Add flag with access perms for each argument. Add ro/rw versions of argument building functions. General cleanup.
* Turn /dev/geom.ctl from a GEOM class into a plain character device driverphk2003-03-241-94/+15

| | | | | | | | | | | don't take the detour over the I/O path to discover them using getattr(), we can just pick them out directly. Do note though, that for now they are only valid after the first open of the underlying disk device due compatibility with the old disk_create() API. This will change in the future so they will always be valid. Sponsored by: DARPA & NAI Labs.
