interface and the address allocated, to roll everything back if the
mount fails:
-put an interface pointer into "struct nfs_diskless" to have it
available for cleanup, don't pass it around anymore where the
"struct nfs_diskless" is already passed
-add a "cleanup" function which shuts the interface down
-in the protocol-specific parts, either return with "everything
ready" or "completely shut down"
-use common functions for interface initialization and shutdown
-add a function to delete all routes associate to an interface
(why is this necessary and not done by ~IFF_UP?)
g/c diskless swap stuff
general cleanup
conditional on a particular configuration method.
The global flags "nfs_boot_rfc951" and "nfs_boot_bootparam" control
independantly if the functions are actually called. (Previous meaning
of "nfs_boot_rfc951" was "either-or".)
interface. Without this, NFS_BOOT_NETMASK could be useless in
subnetting envirinment.
2. Comment out unneeded NFS swap related stuff.
Closes PR kern/3918.
The RPC/bootparamd calls to get the root and swap paths are now done
in nfs_boot_init() instead of nfs_boot_getfh(), so the latter now just
does the RPC/mountd call. Also changed some panics into error returns.
Some of the stuff (e.g., rarpd, bootpd, dhcpd etc., libsa) still will
only support Ethernet. Tcpdump itself should be ok, but libpcap needs
lot of work.
For the detailed change history, look at the commit log entries for
the is-newarp branch.
network interface to use.
- If any part of the NFS root mount process fails, don't panic.
Simply return the appropriate error and let the caller recover.
- Try V3 first for diskless booting. Fall back to V2 if V3 fails.
- optionally (option NFS_BOOT_TCP) try a TCP mount first
for diskless booting. Fall back to UDP if it fails.
- Enable switching between UDP and TCP for remounts.
device and a printable "external name" (name + unit number), thus eliminating
if_name and if_unit. Updated interface to (*if_watchdog)() and (*if_reset)()
to take a struct ifnet *, rather than a unit number.
* Convert several data structures to use queue.h.
* Split in_pcbnotify() into two parts; one for notifying a specific PCB, and
one for notifying all PCBs for a particular foreign address.
