WOL with forcedeth broken since f55c21fd9a92a444e55ad1ca4e4732d56661bf2e

[Philipp Matthias Hahn]

Hello!

Somewhere between 2.6.26 and 2.6.27 WOL stopped working on my MS-7350
motherboard with an "nVidia Corporation MCP51 Ethernet Controller (rev a3)".
	"etherwake 00:19:db:f2:e1:35" did not work
	"etherwake 35:e1:f2:db:19:00" did work
Since I did a BIOS update during the same time window I (wrongly) put
the fault on the BIOS. (See /sys/class/dmi/id/modalias for yourself:
dmi:bvnAmericanMegatrendsInc.:bvrV1.7:bd07/29/2008:svnMSI:pnMS-7350:pvr1.0:rvnMSI:rnMS-7350:rvr1.0:cvnToBeFilledByO.E.M.:ct3:cvrToBeFilledByO.E.M.:
)

Today I finally found the time to test various old versions of
"drivers/net/forcedeth.c" and also did a "git-bisect v2.6.26 v2.6.27"
which lead to the following culprit:

    |    [netdrvr] forcedeth: setup wake-on-lan before shutting down
    |
    |    When hibernating in 'shutdown' mode, after saving the image the suspend hook
    |    is not called again.
    |    However, if the device is in promiscous mode, wake-on-lan will not work.
    |    This adds a shutdown hook to setup wake-on-lan before the final shutdown.

    my servers with nvidia ck804 and mcp55 will reverse mac address with kexec.
    
    it turns out that we need to restore the mac addr in nv_shutdown().

Reverting that patch on top of drivers/net/forcedeth.c from 2.6.28.2
resolves the problem for me.
I DON'T use kexec, just simple poweroff.

can not find the reason why the WOL doesn't work...

please post
1. boot log for just after AC is pluged-in... ===> you should have
"nv_probe: set workaround bit for reversed mac addr"
2. and boot log after boot from WOL...==> you have have "nv_probe: set
workaround bit for reversed mac addr" too.

looks like your BIOS, already reverse the MAC addr...

please check attached ... Rafael, wonder if will break suspend/resume...

[PATCH] forcedeth: keep mac addr to orignal

Impact: fix mac reverse for wol

some BIOS may already reverse that, try to don't touch the mac addr, so don't
confuse the WOL

Well, it doesn't look like it's going to, but testing is necessary.

Patches against ext3 have been posted by Jan Kara and have been sucked
into the mm tree.  I don't know if Andrew is planning on waiting until
the next merge window, or is planning on pushing it sooner given that
it is a regression.  (These supercede the ones currently posted by
Eric in the BZ entry.)

Similar patches have been posted against ext4, and I will be handling
them in the ext4 tree.

Yes, I have jbd-fix-return-value-of-journal_start_commit.patch and
revert-ext3-wait-on-all-pending-commits-in-ext3_sync_fs.patch queued
for 2.6.29.

The secret algorithm for determining this is to peek in the series file
(http://userweb.kernel.org/~akpm/mmotm/series) and see where I positioned the
patch:

Re: [Bug #12393] debugging in dosemu causes lots of 'scheduling while atomic'

[Michal Suchanek]

As I said earlier I have received a patch that I applied locally and
that fixes the problem.

As to if and when the patch actually appears in the kernel is out of
my control, and nobody told me that it was applied.

If you believe it was applied to a kernel version that is readily
available for download I am wiling to test such version.

Thanks

Strage, at the moment I can't seem to reproduce the problem. I've
switched back to the version of 2.6.28.3 and now it seems to work.
I'll continue with tesing.

Some additional data:
The BIOS-upgrade tool (Afud408.exe) resets the MAC address. I had to run
the tool a second time to re-programm the MAC-address using its /M
option. I useed the unreversed MAC-address back than.
I also tried the reversed address once, but after that forcedeth.c
complained about a wrong MAC-address.

If I completely turn off the power (pull the plug), WOL doesn't work,
even when it's enabled in the BIOS.

Only after I'v started Linux, do "echo NMAC > /proc/acpi/wakeup" and
"ethtool -s eth0 wol g" does it work again.

Nether the less here's the output of dmesg:
        forcedeth: Reverse Engineered nFoce ethernet driver. Version 0.61.
        ACPI: PCI Interrupt Link [LMAC] enables at IRQ 23

that means your BIOS doesn't reverse mac addr.
this is the one for new BIOS or old BIOS?

OK, but for now I'll close the bug as unreproducible.

The "echo NMAC > /proc/acpi/wakeup" thing shouldn't be necessary if you do
"ethtool -s eth0 wol g".

Just this morning I had to use the reverted address to wake up my
desktop PC after 6 hours of poweroff.

Yesterdays tests were domething like the following:
	Grub: Linux "loglevel=9 ignore_loglevel break=modules"
	dmesg -c > /dev/null
	modprobe forcedeth
	dmesg
	ethtool -s eth0 wol g
	echo NMAC > /proc/acpi/wakeup
	reboot to Grub using Alt-SysRq-B
	Grub: "halt"
I have to reboot back to Grub, since doing a "poweroff" from initrd or
pressing Alt-SysRq-O seems to turn of WOL.

...

Will try.

I did some structured tesing:

1. WOL does _not_ work at all when I do:
	(grub) boot into initrd
	(initrd) modprobe forcedeth
	(initrd) ethtool -s eth0 wol g
*	(initrd) poweroff

2. WOL does _not_ work at all when I do:
	(grub) boot into initrd
	(initrd) modprobe forcedeth
	(initrd) ethtool -s eth0 wol g
*	(initrd) Alt-SysRq-O

3. WOL works using the _un-reversed_ MAC when I do:
	(grub) boot into initrd
	(initrd) modprobe forcedeth
	(initrd) ethtool -s eth0 wol g
*	(initrd) Alt-SysRq-B
*	(grub) halt

4. WOL works using the _reversed_ MAC when I do:
	(grub) boot into initrd
	(initrd) modprobe forcedeth
	(initrd) ethtool -s eth0 wol g
	(initrd) exit
*	(Debian) poweroff

If I do the poweroff from linux (either initrd or Debian), forcedeth
seems to display some messages just before poweroff. I'll try to get
hands on a Serial-USB-Converter and a NULL-modem-cable to capture it,
since my laptop is legacy-free :-(

There is a fix against scsi-misc:

http://marc.info/?l=linux-scsi&m=123371501613019&w=2

I might need to fix it in a different way though.

There are other pending patches to fix other sg oops in scsi-misc so
the above fix can't be cleanly applied to 2.6.28.X. I'll send a patch
for 2.6.28.X once I get SCSI maintainer's ACK on it.

Sorry for the inconvenience,

Still around.  Btw, I'm not sure it's a regression as I only started
using virtio_blk heavily during the 2.6.28 cycle.

I never received the email referring to a particular commit because
I am not subscribed to LKML.  The commit revert seemed to work OK on 
gameport.c, but I get an error that gameport.h requires merge 
resolution.

Can you send the gameport.c and gameport.h files to me with the
reverted commit, or tell me how to get this resolved?

Please CC me directly.

I CCed you, but your ISP blacklisted both of my SMTP servers I have tried 
for no apparent reason.

Please try the patch below. It's not a simple revert of 6902c0be, needed 
some manual tweaking.

Well, assuming that it is a regression raises its chances to be fixed faster. ;-)

Hmm, I had not tried WOL for some time.
With 2.6.29-rc3 is see the following behaviour:

State            WOL Behaviour
------------------------------
shutdown         reversed MAC
disk/shutdown    reversed MAC
disk/platform    OK

Apparently nv_restore_mac_addr() restores the MAC in the wrong order
for WOL (at least for my PCI_DEVICE_ID_NVIDIA_NVENET_15).  platform
works, because the MAC is not touched in the nv_suspend() path.

A possible fix might be to only call nv_restore_mac_addr() if
system_state != SYSTEM_POWER_OFF.

Your patch seems to work for my system, too. (Expect for the case where
I do "poweroff" from busybox or do Alt-SysRq-O; Debians version works,
as long as I remove the '-i' option:
	-i     Shut down all network interfaces just before halt or reboot.
