sanity check, but it is too easy to run into, eg: making an ACL syscall
when no filesystems have the ACL implementation enabled.
The original reason for the panic was that the VOP_ vector had not been
assigned and therefor could not be passed down the stack.. and there
was no point passing it down since nothing implemented it anyway.
vop_defaultop entries could not pass it on because it had a zero (unknown)
vector that was indistinguishable from another unknown VOP vector.
Anyway, we can do something reasonable in this case, we shouldn't need
to panic here as there is a reasonable recovery option (return EOPNOTSUPP
and dont pass it down the stack).
Requested by: rwatson
to recycle inodes after a destroy_dev() but not until all mounts
have picked up the change.
Add support for an overflow table for DEVFS inodes. The static
table defaults to 1024 inodes, if that fills, an overflow table
of 32k inodes is allocated. Both numbers can be changed at
compile time, the size of the overflow table also with the
sysctl vfs.devfs.noverflow.
Use atomic instructions to barrier between make_dev()/destroy_dev()
and the mounts.
Add lockmgr() locking of directories for operations accessing or
modifying the directory TAILQs.
Various nitpicking here and there.
for them does not belong in the IP_FW_F_COMMAND switch, that mask doesn't even
apply to them(!).
2. You cannot add a uid/gid rule to something that isn't TCP, UDP, or IP.
XXX - this should be handled in ipfw(8) as well (for more diagnostic output),
but this at least protects bogus rules from being added.
Pointy hat: green
to allow commonality between varying platforms. This is a step
towards parsing the diskless configuration information with MI code
inside the kernel.
Export the interface hardware address to the kernel, so that it is possible
to determine the boot interface with certainty.
Export the NFS filehandle for the root mount to the kernel, so that the
kernel does not need to perform a mount RPC call.
chgsbsize(), which are called rather frequently and may be called from an
interrupt context in the case of chgsbsize(). Instead, do the hash table
lookup and maintenance when credentials are changed, which is a lot less
frequent. Add pointers to the uidinfo structures to the ucred and pcred
structures for fast access. Pass a pointer to the credential to chgproccnt()
and chgsbsize() instead of passing the uid. Add a reference count to the
uidinfo structure and use it to decide when to free the structure rather
than freeing the structure when the resource consumption drops to zero.
Move the resource tracking code from kern_proc.c to kern_resource.c. Move
some duplicate code sequences in kern_prot.c to separate helper functions.
Change KASSERTs in this code to unconditional tests and calls to panic().

Add support for the SOHOware PCMCIA Ethernet card, model ND5100-E.
This seems to be a re-badged NDC (National Datacomms. Corp) card.
It needs a quirk entry due to lack of manufacturer tuple in the CIS.
For some reason, the 'Tx/Rx' LED on the connector module is inverted
such that it is off during network activity...
at this point):
Replace all '#ifdef DEBUG' with '#ifdef NULLFS_DEBUG' and add NULLFSDEBUG
macro.
Protect nullfs hash table with lockmgr.
Use proper order of operations when freeing mnt_data.
Return correct fsid in the null_getattr().
Add null_open() function to catch MNT_NODEV (obtained from NetBSD).
Add null_rename() to catch cross-fs rename operations (submitted by
Ustimenko Semen <semen@iclub.nsu.ru>)
Remove duplicate $FreeBSD$ tags.
Some have dual host->PCI bridges for the same logical pci bus (!), eg:
some of the RCC chipsets. This is a 32/64 bit 33/66MHz and dual pci
voltage motherboard so persumably there are electical or signalling
differences but they are otherwise the same logical bus.
The new PCI probe code however was getting somewhat upset about it and
ended up creating two pci bridges to the same logical bus, which caused
devices on that logical bus to appear and be probed twice.
The ACPI data on this box correctly identifies this stuff, so bring on
ACPI! :-)
bus/slot/function numbers. The old PCI code used other markers or
something, but without it here under the new pci code it is very hard to
tell which device is which (this only affects bootverbose mode).
unsupported address family is used on localhost interface.
looutput: af=0 unexpected
Speculation as to the reasons for my seeing this error are welcome, of
course. :-)
