revision 1.21
date: 1999/10/15 17:29:20; author: imp; state: Exp; lines: +3 -3
Reorganize the attachement point for pcic (it was unattached and
floating before). Attach pccard devices to pcic, one per slot
(although this may change to one per pcic). pcic is now attached to
isa (to act as a bridge) and pccard is attached to pcic, cbb and
pc98ic (the last two are card bus bridge and the pc98ic version of
pcic, neither of which are in the tree yet). Move pccard compat code
into pccard/pccard_compat.c.
THIS REQUIRES A CONFIG FILE CHANGE. You must change your pcic/card
entries to be:
# PCCARD (PCMCIA) support
controller pcic0 at isa?
controller pcic1 at isa?
controller card0
The old system was upside down and this corrects that problem. It
will make it easier to add support for YENTA pccard/card bus bridges.
Much more cleanup needs to happen before newbus devices can have
pccard attachments. My previous commit's comments were premature.

Make some tweaks to the RealTek driver:
- Fix a bug in rl_rxeof() handler: in the case where the packet wraps
from the end of the receive buffer back to the beginning, we need to
insure that at least sizeof(ether_header) bytes make it into the first
mbuf. If we don't, then doing eh = mtod(m, struct ether_header *)
loses. To avoid this, we use m_pullup() to suck at least MHLEN -
RL_ETHER_ALIGN bytes into the first mbuf, which should also help
small packets fit into a single mbuf.

and jack it up when TX underruns are detected.
- Also improve TX error recovery: kick the chip in the head with a
reset/init sequence to make sure it recovers afer a transmit error.

Fix the duplicate filenames that are the result of using getdents.
glibc2 defines struct dirent differently than the Linux kernel does.
The getdents function therefore needs to read a heuristically defined
number of kernel dirents to satisfy the request. In case where too
many kernel dirents have been read, the function lseeks on the
directory so that a next call will start with the right dirent. The
offset used in lseeking is the offset-field in the last dirent passed
to the application. This can only mean that the offset-field holds
the offset of the next dirent and not the offset of the dirent itself.

A tentative agreement has been reached in regards to a procedure
to remove 'b'lock devices. The agreement is, essentially, that
block devices will be collapsed into character devices as a first
step (though I don't particularly agree), and raw device names 'rxxx'
will become simply 'xxx' in devfs in the second step (i.e. no 'rxxx'
names will exist). The renaming will not effect the original /dev
and the expectation is that devfs will eventually (but not immediately)
become the standard way to access devices in the system.
If it is determined that a reimplementation of block device access
characteristics is beneficial, a number of alternatives will
be possible that do not involve resurrecting the 'b'lock device class.
For example, an ioctl() that might be made on an open character device
descriptor or a generic buffered overlay device.
This commit removes the blockdev disablement sysctl which does not
apply to the solution that was reached.

quoting << Martin_Blapp
- Completly changed the internals of umount(8). We do three
checks now to see if 'argv' is in the mounttable. It they
all fail, we return to main and print a warning.
- fixed the umount mount-order. The checks are rather complex
to do this. Cause umount(8) should also be able to unmount
several devices at once ('umount -a', 'umount -A',
'umount /mnt /mnt2'), the mount-order get's important.
I added checks to mark and unmark already unmounted devices.
- Various fixes with nfs-unmounts (no rpc-calls were done,
or they were done although there was an existing mount).
Since we allow overlay-mounts, we should also handle them
properly.
- Translate the deprecated nfs-syntax with '@' to ':' like
mount_nfs does. The ':' syntax has now precedence, but '@'
still works.
- 'umount -v' is now fixed for all cases and doesn't print
garbage like two times the mountpoint etc.
- removed non documented and useless umount '-F'.
- hanged nfsmounts can now unmounted 'without' any problems.
I've removed stat() and realpath() checks on the mountpoint.
Instead we just do a realpath() on the basedir of the
mountpath and add the dirname again.
Implemented this as an idea from phk. But there are still
vfs-restrictions if the nfs_mount is busy. If there are
unwritten metadata on a hanged nfs-mount, and we modify
nfs_vfsops.c to not return EBUSY, we get a deadlock :(
The problem has now moved from userland to kernel.
- removed the BUGS part from the umount(8) manpage.
- Converted it to ANSI C (more than 60% of the code have
changed).
