Alan,
I have just sent you the prepare/withdraw/publish_etherdev patch for the ethernet
devices. There's a copy (80kbytes) at
http://www.uow.edu.au/~andrewm/linux/init_etherdev.patch
It was fairly clean and I don't expect much breakage at all from this.
I could only test the module and non-module error paths, but surely
this patch represents an aggregate bug reduction :)
eepro100.c and acenic.c should still be 2.2-compatible.
The patch includes some other xmas goodies, including:
- An update to 3c59x which allows it to support 3com's
recently-released 3c905CX. This is a bit ugly, but it gets people up
and running until I can get my hands on one of these things.
- Fixed locking and write barriers in natsemi.c, as discussed with Manfred.
- Fixed a fair number of unchecked kmallocs and error-path resource leaks.
- comx.c needs proc_get_inode(), so that has been exported.
- dmfe.c was allowing itself to be unloaded whilst remaining
registered on the PCI device list. crash, crash.
- Several drivers were not declaring their module parms and were not
loadable with recent modutils.
- Several drivers had incorrect module parm declarations are were not
loadable with recent modutils.
- All affected drivers now use SET_MODULE_OWNER instead of MOD_INC/DEC.
- drivers/net/depca.c oopses on boot because egcs-1.1.2 is
miscompiling strstr(). It's failing to honour the clobber on edi. I
put a workaround in depca.c.
A workaround in strstr is to force `ct' to be a memory operand, not
a general operand. Shouldn't we do this? Or, even better, kill the
asm strstr and use the one in lib/string.c?
I think aironet4500_card.c is missing some module refcount handling,
but I didn't address this.
I'll send you the rrunner.c patch (maybe Jes has already done so?).
Then if/when this stuff comes back to me I can do a final patch to
remove the now-unused init_etherdev, init_fcdev, init_hip_dev,
init_fddidev and init_trdev functions. Then we're done.
The CardServices drivers use a bare register_netdev() and I think they
have the same race. But that's orthogonal to the current work.
Thanks.
