fix Dennis Fortin's problem for good, if I've got it figured out right.
(The problem was that a `struct ifaddr' could get deleted out from under
the current requester, thus leaving him with an invalid interface pointer
and causing even more bogus accesses.)
routines (and merged local changes). The changed vnode_pager_uncache
gets rids of the bogosity that you can call the routine without
having the vnode locked. The changed vnode_pager_umount properly locks
the vnode before calling vnode_pager_uncache.
It was previously after the VOP_RENAME and the reference and lock on
the vnode had already been lost, allowing interesting internel
inconsistencies. This is one of the two reasons why freefall was crashing
every hour or two (the other being nullfs bugs).
Don't call vnode_pager_uncache in revoke(). revoke() is only allowed on
VCHR and VBLK vnodes.
during the FS sync. The system would appear to hang momentarily
if there was a large backlog of I/O. This is because the vnode
remains locked during the output - preventing normal character
I/O. The problem was exacerbated by the FFS contiguous block
allocation fixes and a semi-broken disksort(). The inode/date
will still be synced during a normal FS dismount and whenever
the inode is changed for other reasons.
probe of the device and shouldn't affect normal operation. It seems that
some version of the aic7870 are extreamly slow in clearing their interrupt
register so the added delay is required to ensure we don't poll a stale
interrupt value.
Clean up debugging printfs and stuff superflous output into #ifdef AHC_DEBUG.
Ensure that sdtrpending and wdtrpending are cleared in all cases after
we recieve an SDTR or WDTR message.
With this commit, the 294x should work or at least be much closer to
working properly.
a device specific shutdown routine for devconf. Assign the value of this
to the kern_devconf struct. Implement a device shutdown routine for if_de
that disables the device. This will stop the device from corrupting memory
after a reboot.
VFCF_NETWORK (this FS goes over the net)
VFCF_READONLY (read-write mounts do not make any sense)
VFCF_SYNTHETIC (data in this FS is not real)
VFCF_LOOPBACK (this FS aliases something else)
cd9660 is readonly; nullfs, umapfs, and union are loopback; NFS is netowkr;
procfs, kernfs, and fdesc are synthetic.
submitting them as context diffs for the following files:
sys/netinet/ip_mroute.c
sys/netinet/ip_var.h
sys/netinet/raw_ip.c
usr.sbin/mrouted/igmp.c
usr.sbin/mrouted/prune.c
The routine rip_ip_input in raw_ip.c is suggested by Mark Tinguely
(tinguely@plains.nodak.edu). I have been running mrouted with these patches
for over a week and nothing has seemed seriously wrong. It is being run in
two places on our network as a tunnel on one and a subnet querier on the
other. The only problem I have run into is that mrouted on the tunnel must
start up last or the pruning isn't done correctly and multicast packets
flood your subnets.
