1239674238 There seems to be a problem that the order of disk write operation being
incorrect due to a missing check for some dependency.  This change
avoids the freelist corruption (but not the temporarily inconsistent
state of the file system).

A message is printed as a reminder of the under lying problem when a
pagedep structure is not freed due to the NEWBLOCK flag being set.

11457bbf08 While in the interrupt loop, check for a bogus interrupt value of 0xff.
This may be returned if the underlying hardware is a pc-card which has

b794010414 Move out the files from src/sys/isa/ic/ to src/sys/dev/ic/, so they
can be made userland-visible as <dev/ic/...>.  Also, those files are
not supposed to contain any bus-specific details at all, so placing
them under .../isa/ has been a misnomer from the beginning.

The files in src/sys/dev/ic/ have been repo-copied from their old
location (this commit is a forced null commit there to record this
message).

81aad9b606 If the chip isn't in power state D0, put it in power state D0. I
elected to do this in the probe rather than the attach so that we don't
disturb things which this might reset.  different cards have different
quirks, according to their datasheets.

This should fix the "I booted in windows and rebooted to FreeBSD and
now things don't work" problem.

58c13f9b7a Add new pci attachment for pcic. This supports pci cards as well as
card bus bridges.

We now always use pci interrupts for pci cards.  This will allow us to
more easily configure things.  You must change your IRQ lines in
/etc/pccard.conf to match what we've probed.  I'm not sure the right
way to deal with this right now.

Development of pci pcmcia has been funded by Monzoon Networks AG.  I
am grateful for their generosity.

1b3e974a71 The pipe_write() code was locking the pipe without busying it first in

f20688d55c #defines for pci way interrupt routing. 2001-06-04 03:36:22 +00:00
Warner Losh
94b197e96d Move the pcic interrupt from pcic.c to pcic_isa.c. The ISA handling
for card change interrupts is different than the pci stuff that's
coming soon.  Set the management irq in different ways.  If
pci_parallel interrutp routing, then use the PCI way of getting
interrupts.  Move polling mode into pcic_isa since when we're routing
via pci polling doesn't work because many bridges (systems hang solid).

If we're routing interrupts via pci, they can be shared, so flag them
as such.

Note, this doesn't actually change anything since the pci attachment
isn't quite ready to be committed.

690a6055ff Prevent denial of service using bogus fragmented IPv4 packets.
A attacker sending a lot of bogus fragmented packets to the target
(with different IPv4 identification field - ip_id), may be able
to put the target machine into mbuf starvation state.

By setting a upper limit on the number of reassembly queues we
prevent this situation.

This upper limit is controlled by the new sysctl
net.inet.ip.maxfragpackets which defaults to 200,
as the IPv6 case, this should be sufficient for most
systmes, but you might want to increase it if you have
lots of TCP sessions.
I'm working on making the default value dependent on
nmbclusters.

If you want old behaviour (no upper limit) set this sysctl
to a negative value.

If you don't want to accept any fragments (not recommended)
set the sysctl to 0 (zero).

a98dc5e6a7 First, wrap the if_up() call into splimp()/splx() because
if_up() must be called at splnet or higher.
Second, set the IFF_RUNNING flag on an interface after its
resources (i.e. tunnel source and destination addresses)
have been set. Note that we don't set IFF_UP because it is
if_up()'s job to do that.

e46e7fa2c2 Only touch the PCR register in order to set bits for the fxp driver.
The 3C509-TX card apparently had a slightly different version of the
chip, and has problems when this register is set.  The problem does
not appear on the 3C509{BC} cards, but since only the fxp driver needs
specific bits set, conditionalize on that.

canonical: define a versioned struct xswdev, and add a sysctl node
handler that allows the user to get this structure for a certain device

This new node handler, vm.swap_info, replaces the old vm.nswapdev
and vm.swapdevX.* (where X was the index) sysctls.

3a4f29da1e The orm device. This device gobbles up the Option ROMs in the ISA
memory I/O space.  Otherwise, our resource allocation system might
mistakenly assign pccard, plug and play devices or other things
addresses that conflict with ROMs.

I cleaned up his code a little from the submited driver: style(9)
issues, commentary on why something that looks incorrect really is
correct.  Also noted that while a checksum field is defined for the
ROMs, enough common hardware neglects it to make it not worthwhile
checking.

150cd07213 Resurrect platform.pci_intr_map() and essentially undo the effects of
the interface conversion to platform.pci_intr_route().  I've left the
platform.pci_intr_route() function pointer in place, as well as
alpha_pci_route_interrupt(), but no platform currently implements it.

To work around the removal of alpha_platform_assign_pciintr(cfg);
from the pci probe code, I've hooked in calls to platform.pci_intr_map()
in pcib_read_config (similar to the x86 APIC_IO ifdef in pci_cfgregread)
for every chipset that has a platform which needs it.

While here, I've removed the interupt mapping/routing code from the
AS2x00 platform because its not required (it has never been present in
-stable).

51716196a4 Support /dev/tun cloning. Ansify if_tun.c while I'm there.
Only tun0 -> tun32767 may now be opened as struct ifnet's if_unit
is a short.

It's now possible to open /dev/tun and get a handle back for an available
tun device (use devname to find out what you got).

The implementation uses rman by popular demand (and against my judgement)
to track opened devices and uses the new dev_depends() to ensure that
all make_dev()d devices go away before the module is unloaded.
