for two kauth_cred_t rather than kauth_cred_t and struct proc *.
advise against using it in the man-page; it should be used only in cases
where we either don't have an object-specific op or when we can't easily
use one.
introduce fileassoc(9), a kernel interface for associating meta-data with
files using in-kernel memory. this is very similar to what we had in
veriexec till now, only abstracted so it can be used more easily by more
consumers.
this also prompted the redesign of the interface, making it work on vnodes
and mounts and not directly on devices and inodes. internally, we still
use file-id but that's gonna change soon... the interface will remain
consistent.
as a result, veriexec went under some heavy changes to conform to the new
interface. since we no longer use device numbers to identify file-systems,
the veriexec sysctl stuff changed too: kern.veriexec.count.dev_N is now
kern.veriexec.tableN.* where 'N' is NOT the device number but rather a
way to distinguish several mounts.
also worth noting is the plugging of unmount/delete operations
wrt/fileassoc and veriexec.
tons of input from yamt@, wrstuden@, martin@, and christos@.
- note that ifconfig(8) create subcommand is required before slattach(8)
- network addresses aren't defined by slattach(8) but ifconfig(8)
- Add a BUGS section in slattach(8) to note that currently there is no way to
specify/see an interface name to be attached
- move description about link[0-2] flags from slattach(8) to sl(4)
(rather than adding a new description...)
- move description about SLIP limitations to a new BUGS section in sl(4)
- remove inappropriate MLINKS of slip.8 to slattach.8
- create MLINKS of slip.4 to sl.4 instead
- add some more xrefs
Ok'ed by christos, and closes PR kern/33672 and PR bin/33923.
- Update ctxsw(9) to reflect reality a little better
- chooselwp doesn't exist in the kernel so remove the man page.
- Remove the references to chooseproc which existed briefly.
