That's EVERY SINGLE driver that has an entry in conf.c..
my next trick will be to define cdevsw[] and bdevsw[]
as empty arrays and remove all those DAMNED defines as well..
Each of these drivers has a SYSINIT linker set entry
that comes in very early.. and asks teh driver to add it's own
entry to the two devsw[] tables.
some slight reworking of the commits from yesterday (added the SYSINIT
stuff and some usually wrong but token DEVFS entries to all these
devices.
BTW does anyone know where the 'ata' entries in conf.c actually reside?
seems we don't actually have a 'ataopen() etc...
If you want to add a new device in conf.c
please make sure I know
so I can keep it up to date too..
as before, this is all dependent on #if defined(JREMOD)
(and #ifdef DEVFS in parts)
These functions went away:
enosys (hasn't been used for some time)
enxio
enodev
enoioctl (was used only once, actually for a vop)
if_tun.c:
Continued cleaning up...
conf.h:
Probably fixed the type of d_reset_t. It is hard to tell the correct
type because there are no non-dummy device reset functions.
Removed last vestige of ambiguous sleep message strings.
instead of with none. The first (struct proc *) arg is used if lkmnosys()
if is actually called.
Implement lkmnosys() with the correct number and type of args so that
the first of them can be used and the others won't need to be fixed
lated.
some (hopefully) less offensive stupidity:
If we detect that a user has loaded a module that fails to initialize
itself correctly, panic. There really isn't a safe way to recover from
something like this; we can't know that the module is bad until after
the entry point is called, by which time it's too late to do anything
about it.
- Add $Id$ string.
- Fix comment ("we might *not* be able to unload the
module afterwards without panicking...")
- Get rid of variable 'j' that I used in name checking
for(;;) loop and use 'i' instead (I thought there'd be
a problem with this, but there isn't).
if_tun_mod, etc...) from crashing the system. These modules are useful,
but because they don't yet have proper load()/unload() functions,
they can lead to panics: if, for example, you load the if_ppp module,
any user can panic the system by running modstat.
You can also hang the system outright if you try to unload the PPP
module too.
Changes are as follows:
- Save the name passed to us during the RESERVE stage for name matching
(we can't load if_ppp_mod twice: we've have two ppp0's and two ppp1's,
which is beyond strange). This makes the lkmexists() cheks somewhat
redundant, but there's no way around it that I can see.
- If we call the module entry point and find that we have no lkm_any
structure in our 'private' section, create a fake one. This keeps
modstat happy. We mark such modules as LM_UNKNOWN.
- Don't allow LM_UNLOAD modules to be unloaded: it just ain't
possible. (Unless someone wants to write a pppunattach() function. :( )
- In lkmunreserve(), mark private.lkm_any as NULL so we don't get
confused later. I think this is bogus, but I can't prove it.
XXX: the name matching used to keep the user from loading two
instances of the same module can easily be defeated simply by
changing the module name or, in the case of the oddball modules,
simply by renaming the module files. I haven't found a nice simple
way to tell one module from another.
- set args->lkm_offset correctly so that VFS modules can be unloaded
- initialize _fs_vfsops.vfc_refcount correctly so that VFS modules can
be unloaded
- include kernel.h in a few placves to get the correct definition of DATA_SET
use of timeout_t -> timeout_func_t in aha1542 and aha1742 drivers.
2) fix a bug in the portalfs that was uncovered by better prototyping -
specifically, the time must be converted from timeval to timespec
before storing in va_atime.
3) fixed/added some miscellaneous prototypes
