I did the pull from Linus's tree, but the problem is that nothing in
the IGB driver seems to bring that pci-aspm.h include file in.
Thus it doesn't build:
drivers/net/igb/igb_main.c: In function 'igb_probe':
drivers/net/igb/igb_main.c:1018: error: 'PCIE_LINK_STATE_L0S' undeclared (first use in this function)
drivers/net/igb/igb_main.c:1018: error: (Each undeclared identifier is reported only once
drivers/net/igb/igb_main.c:1018: error: for each function it appears in.)
make[3]: *** [drivers/net/igb/igb_main.o] Error 1
make[2]: *** [drivers/net/igb] Error 2
make[2]: *** Waiting for unfinished jobs....
So, I can't see how it builds successfully on any platform :-)
Doing a "git grep pci-aspm.h" shows just a few *.c files under drivers/pci
and nothing else.
Please fix this up.

The kerneloops list is helpful, and improving it is great, but it will
never be able to cover 100% of all problems on 100% of all computers.

You miss my point:
We agree that the kerneloops list is not perfect.
And usually the bugs with a trace that go into the list are the
ones that are easier to debug and fix, while the others might be
much harder to debug.
If one takes Linus' "simple rule of thumb" literally then a hard to
debug bug without any messages anywhere mustn't be fixed outside of
a merge window. This literal reading is what doesn't make sense.

the pci_disable_device() is done on an enabled device, so your

I thought about the solution, but the pci device is completely setup
and enabled in the init function so disabling it at that point and
enabling it in open() again sounds silly to me. pci_enable_enable/disable
is already done in .init/.remove and .suspend/.resume, so it looked
more obviuos to not let close() do the pci_disable_device().

Among the patches David rejected based on what Linus said was
Thomas' patch [1].
It is not a "really important bug" and does not affect "huge number
of users".
But it passes Documentation/stable_kernel_rules.txt, and can we agree
that if it gets submitted for 2.6.27.1 it will likely pass review and
get applied?
That's the kind of patches I'm talking about.

Thomas' patch [1] will fixes a bug of a kind that will likely never
make it to your list.
And the same also e.g. goes for bugs where your machine is completely
dead (no SysRq possible) with nothing in the logs.
The kerneloops lists are quite valuable, but they can never cover all
classes of fatal bugs.

if it has any kind of backtrace, it'll be there if it's a common
problem that hits many users.

Well, remember that patches that get published for -stable do have to
go through an extra review process. It's not true that any "obviously
correct" bug fix gets automatically published in -stable. Sometimes
bug fixes do get rejected for -stable because they are too risky, or
require more time for testing in the -rc series before they are deemed
suitable for -stable.
Looking at 2.6.26, there is currently about 195 patches queued up,
which is certainly not all of the bugs fixed during the 2.6.27
development cycle. Some of it is that some developers aren't as
aggressive about nominating patches for backporting to 2.6.26, and
some of it is that only the really *important* bugs get this treatment.
But, I bet that if there was a major embarassing problem where someone
abused the process by submitting an "obviously correct" patch that
ended up breaking things for a others, the end result would be that
the -stable team would start cracking down and start using more strict
criteria about what would be considered allowable for publishing in
-stable.
I'll remind people that the original rule was that new features were
only allowed in -rc1, and bug fixes in -rc1 and -rc2. But because
that got abused, Linus is now saying that only regression bug fixes
are allowed post -rc1. My belief is that part of the reason for this
is that Linus is a self-described soft touch, and by stating a
draconian rule, he's hoping that subsystem maintainers like David will
lay done the law, and prevent the really serious abuses (where people
starting submitting "obvious bug fixes" in -rc5 and -rc6 that caused
regressions which in turn ends up extending the release cycle).
If it's a really important bug, and it affects a huge number of users,
or it's really bad security bug, the reality is that exceptions will
be made to the rules. But exceptions need to remain exceptions for
extraordinary situations, not everyday occurrences. And of course, if
the bug does affect a huge number of users, someone should be asking
the question why it wasn't detected sooner, say before the last merge
window --- and to ask the question how many users is this bug really
going to affect anyway?
At least, that's my take on things,
- Ted

I'm eagerly awaiting to slap this at Linus the next time he dares to
directly apply a patch that only fixes a sparse warning outside of a
merge window... ;-)
More seriously, there's a difference between Linus' "another random
improvement" and an "is even suitable for -stable".
I'm not reading Linus' (Cc'ed) statement the way that a patch that is
appropriate for 2.6.27.1 is not appropriate for -rc now.
If I'm misreading Linus on this it might make sense if they'd discuss
it at their current cabal meeting.

And if it goes in during the next merge window it can immediately go
into 2.6.27.1 (and even 2.6.26.y if it's still maintained), since the
fix fulfills Documentation/stable_kernel_rules.txt .
That doesn't make sense.

that was my feeling as well, but if David wants to see it in the next
merge window, it's his decision. It's not a important fix as the user
base is obviuosly pretty small. And I didn't know about that bug, when
the merge windows was open, so I couldn't fix it "in time".

Such a fix is even suitable for -stable.
If something is considered suitable for -stable, but not for -rc with
one month to go before the release of the kernel, then there's something
wrong in the process.

Hi Dave,
can you confirm that the commit message requirement stands even
if the SHA1 ID references Linus' tree? I personally think that is
reasonable, I just want to confirm that is the requirement.

Why don't you send me the trimmed down pull request for
now, and we can discuss this topic and the specific other
fixes as a follow-on thing?
I also think it matters how many fixes I batch up at once
to merge, btw. So it's better to toss me 4 or 5 fixes
ever could of days, rather than waiting a week and sending
12 or 13.

My impression was that Linus was in Wrath of God(tm) mode <grin> and he
was reacting strongly for effect not being specific.
But I would rather push my fixes, than complain about others' changes :)

Well, obscure subsystems like PCI
PCI: Fix printk warnings in setup-bus.c
PCI: Fix printk warnings in probe.c
or libata
sata_inic162x: enable LED blinking
ata: duplicate variable sparse warning
or ia64 (this is not a regression, but a regular bug)
ia64: fix panic during `modprobe -r xpc'
or bugs that have existed for a long time,
bfs: fix Lockdep warning
As I understand and observe, Linus never ever wants to create
hard-and-fast rules, in this or anything, but set a general guideline
of not putting in changes (fixes or whatever) late in the game that
have a ghost of a chance of creating further problems. That is the
underlying issue... don't create new headaches, _especially_ for large
userbases ;-)
So, I -totally- understand your reaction, but I think this is erring
too far on the side of caution. Oh well...

I personally partly agree with you, but Linus put his foot down and

He continues to take non-regression fixes and minor cosmetic commits
from other trees.
The basic idea is to BALANCE the lateness of -rc with the seriousness of
the problem being fixed, and the technical complexity of the fix itself.
The later the -rc, the more you need to take into account how likely it
is to create additional problems. But did you READ the patches and
extended commit descriptions, to see if additional problems were likely?
Late -rc does not mean "no bug fixes at all except regressions" if you
look at the commits going into the kernel tree.
Late -rc does not mean putting off memory corruption fixes for 6 months.

Because users should not be forced to wait 3 months for fixes, for
admittedly serious bugs, which are ready for them right now. Small,
self-contained, tested, obvious fixes.
There is just something horribly wrong if you are not taking two-line
fixes for memory corruption, even if the problem existed since
kernel 1.2.13.
July 13: 2.6.26 released, merge window opens
July 29: 2.6.27-rc1 released, merge window closes
Sept 20? 2.6.27 release (wild guess)
Dec 25? 2.6.28 release (wild guess)
So if a small, easily-mergable fix for a major bug like an oops
appears on July 30, being strict to your plan has this fix waiting
until almost 2009 (2.6.28 release), a wait of over five months.
That is not serving Linux users, our primary customers.
Complaining about the 8139too change, I can see that (even though
Linus takes that stuff via libata all the time). But about memory
corruption and oopses? Come on.

I don't take that away from what I said.
Why is it so important to fix something "RIGHT NOW" that
has existed forever? Where were these fixes during the
merge window?

He wants the time outside of the merge window to work on fixing
regressions and exploitable problems. This is so that the process
actually ends at some point.

thank you, but the fix I've sent (de2104x) isn't crap. The bug breaks the
current debian-installer for Cobalt Qube1, when it tries to get an
IP address via dhcp.
In my eyes it's a clean and good fix, but I don't care whether it appears
in 2.6.27 or 2.6.28, because debian needs to backport it to 2.6.26
anyway. But declaring bugfixes, which just fixes an very old bug, as
utter crap isn't really nice.

FYI: the WAN bit was actually a regression, 2.6.26 doesn't have this
bug. Nevertheless generic HDLC especially with X.25 is not the
mainstream code so I guess it's probably perfectly acceptable to delay
the fix to minimize the patch flow.

So, my takeaway from this is...
1) Creating a bugzilla entry magically makes a bug fix acceptable?
2) We no longer want "this kills the driver" fixes?
I disagree with that logic, and I seriously doubt Linus wants to turn
away serious fixes to serious problems. Many of these are clearly
needed, just read the extended patch description and the patch itself.
You just rejected patches that (a) fixed dead ethernet [de2104x], (b) fixed an
oops [WAN], and (c) fixed memory corruption [ehea].
I feel like I have just stepped into Odd World, if you don't want fixes
as serious as these.

Look at the analysis I just posted.
Most of those changes were complete and utter CRAP.
Build warning fixes, diagnostic message tidyups. You have
to be kidding me.
Maybe a OOPS fix for common hardware. But not for something
like obscure WAN stuff.
But otherwise, it is in fact strict by the rules regression
list stuff. That's all we're fixing now.
And remember it's not you who gets your head chopped off if
I try to merge in stuff that isn't appropriate now. And Linus
has made it pretty clear what the goals of the non-merge-window
period is, and that is to fix regressions. Otherwise the process
never comes to closure in a reasonable amount of time.

smc91x: fix nowait printout
This one is good but the commit message needs to be fixed up.
It references a raw SHA1 ID but does not give the commit message
header line as well, which is a requirement.
smc91x: SMC_IO_SHIFT platform data support for default case
Ok, but needs commit header line text for referenced commit.
Martin Gebert (1):
[netdrvr] au1000_eth: Spinlock initialisation fix
This problem has existed forever, not a 2.6.27 regression,
and therefore not appropriate.
Mats Erik Andersson (1):
8139too: [cosmetic] fix incorrect register for flash-rom
Cosmetic, indeed. Not appropriate for 2.6.27
Matthew Wilcox (1):
[netdrvr] atl1e: Don't take the mdio_lock in atl1e_probe
This is just lockep noise, and definitely not a 2.6.27 regression
as far as I can tell. So this one has to go.
Sebastien Dugue (1):
ehea: fix phyp debugging typo
DEBUG build fix, not a regression, not appropriate.
Takashi Iwai (1):
drivers/net/skfp/pmf.c: Use offsetof() macro
Cleanup, not appropriate. The code is actually fine but
emits some warnings during the build.
Vlad Yasevich (1):
bonding: Do not tx-balance some IPv6 packets on ALB/TLB bonds
Not a 2.6.27 regression, not appropriate.
Yinghai Lu (1):
forcedeth: call restore mac addr in nv_shutdown path
This appears to fix an entry in the regression list, so OK.
Yoichi Yuasa (1):
cs89x0: fix warning release_irq label
Warning fix, not appropriate for 2.6.27
So, as I said, the vast majority of this stuff is absolulte not
appropriate. Most of it can totally wait for 2.6.28, and not
be merged now.
You can accelerate this process by making sure that every
commit message has a reference to the regression list entry
or a kernel bugzilla that the patch fixes.
So please fix up this patch queue and resubmit, thanks.

Don't stick strictly to that list... We want an oops fix even if
the oops is present in 2.6.26. We want a spinlock fix that makes a
driver work properly on SMP, even if that bug is present in 2.6.26. We
want a build fix, etc.

I'll take another look at the queue and try to give you some
more specific feedback.
I can think of about 3 or 4 entries on the posted regression
list that might be appropriate, so I essentially expected to
see that many commits, give or take one or two.

What do you not want? The two warning fixes (mlx4, cs89x0) akpm seemed
to want in 2.6.27, the 8139too change is cosmetic. The other stuff is
critical AFAICS.

Which of these have regression and/or bugzilla entries?
This is too much and I want to see it trimmed down.

compare_ether_addr()
Maybe fix this in a followup patch?

I think we need to defer the Tulip davicom ID removal patch, because
the tulip driver is the only one that works on sparc64 for davicom
chips, dmfe does not.
That's a regression, so I can't pull this in as-is.
I'm happy to discuss the davicom+sparc64 issue, but for now if
you could simply give me a tree which contains the other
bug fixes we can integrate those now.
Thanks!

How the id removal accord to this debian bug report
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=400837
Looking at dmfe history on git, it is not clearly stated this problem has been
fixed.

Notes:
1) This includes a drivers/atm patch from Al (I don't usually take
drivers/atm patches, but it came straight to me)
2) the drivers/sn change came from the maintainer, so it seemed fine to
push it this way, along with the drivers/net/ioc3-eth changes
3) the forcedeth change is a critical fix

I trust you... Otherwise I wouldn't have volunteered to move my
upstream from Linus to you :)
My main issues/motivations were:
* quite simply, just force of habit: I'm used to basing off of a recent
Linus tree, to guarantee build&boot testing against the latest.
* worry about testing against a too-old tree, where non-networking fixes
may have a relevant impact on my to-be-pushed netdrvr fixes.
But in this case it's fair to say there are no such issues, and it was
mainly just out of habit.
So (as you saw in last email)... rebased and resend.

Keep in mind there are also pending fixes in my net-2.6 tree which
Linus hasn't pulled in yet as well.
I watch Linus's tree closely, and I'll see any potential merge issue
long before it matters, and I always double check before pushing
stuff out to him.
My job as tree master is to deal with all the merge hassles, should
they occur. But up until now everything networking has gone through
my tree and everything is fine.
The net-2.6 tree isn't even a week old. I planned to pull Linus's
tree in right before I leave for a short trip tomorrow afternoon.
I'm really not being allowed to make that choice by how these
changes are being merged to me.
Heck, Jeff even thanked me for making my net-2.6 tree stable and not
rebasing, so his method of merging this stuff is doubly surprising for
me.
Jeff, I really don't want to pull that tree in. Please trust me as
your upstream to handle merging issues, as needed.
Thanks!

I do a test pull and build of net-2.6 into Linus's current tree
before I send Linus a pull request.
If any non-trivial merges are necessary, which hasn't happened yet at
all, I would then do a merge into my net-2.6 tree and resolve the
conflicts.
There is no reason for someone downstream of net-2.6 to do this.

Jeff's choice is a bit surprizing. That being said, it would had been nice
to fast-forward net-2.6 from a442585952f137bd4cdb1f2f3166e4157d383b82
to Linus's upstream before applying the content of
12aa343add3eced38a44bdb612b35fdf634d918c in order to keep the drift

Right. I'm wondering what the problems are that you see with that.
The advantages include earlier warning of merge problems, and avoidance
of duplicate commits--if Jeff's done work that depends on patches that
already upstream, then he either does that work against upstream, or
includes backported patches in the branch he asks you to pull, and you
end up with both the original and the backported patch. Which isn't the
end of the world, but the resulting history seems messier than
necessary.
Or I guess you could both wait to do this merge until you're ready to
pull in Linus's latest?
For non-git-using testers there may be an advantage to always keeping a
tree based on the latest tagged release, as it may simplify providing
them with patches in some cases. But if the goal is to provide a basis
for other maintainer's work, I'd've thought the best policy would be
just to track the tip of every relevant branch (which includes Linus's
in this case).

Because it forces me to pull Linus's upstream into net-2.6,
I don't have any choice in the matter.

Why are either of those a problem?

The whole point of my not rebasing net-2.6 is so that you can always
use it as a base.
With what you've giving me now I either have to:
1) Pull in Linus's tree to net-2.6, then pull from you.
2) Pull in directly from you to get it all.
The whole point of my not touching or rebasing net-2.6 is so that
everyonce can simply use it as a base and just keep working relative
to it.
If you have some need for upstream stuff outside networking (f.e.
some ACPI bug prevents interrupts from working or there is some build
failure), you can clone Linus's tree and pull net-2.6 and your driver
bits into there for building and testing.
Thanks for your consideration, I'm trying to show you mine by
giving everyone a relatively stable tree in which all networking
development can occur.

Pulled and pushed out.
As I mentioned to John Linville just now, I'm going to try
and keep net-2.6 running as long as I can without rebasing.
So you can just keep piling patches into your upstream-davem
branch without fear of my turning your world upside down
with a rebase :-)

Process note: 'upstream-davem' continues the git history that began
the previous push. This sometimes happens when I continue to commit
locally, working in parallel while waiting for changes to hit Linus
upstream.
As current net-2.6.git appears to have the same commit ids that I
submitted in the previous push, this should be no problem at all,
just wanted you to know.
Please pull from 'upstream-davem' branch of
master.kernel.org:/pub/scm/linux/kernel/git/jgarzik/netdev-2.6.git upstream-davem
to receive the following updates:

gcc compalins if you add const and non-const data to the same section
which is the case in this driver.
The bug are exposed now where __devinitdata are no longer an empty define.

Strangely enough, removing the devinitdata from the sis190_pci_tbl
silents the error message here. Do you have an explanation ?

Cool. Either way is fine with me. I just wanted to get a build fix
upstream ASAP, one I was sure would work.

The __devinitdata is OK, it is the following _devinitdata that had to be _devinitconst.

IIId. Synchronization
Most operations are synchronized on the np->lock irq spinlock, except the
-performance critical codepaths:
-
-The rx process only runs in the interrupt handler. Access from outside
-the interrupt handler is only permitted after disable_irq().
-
-The rx process usually runs under the netif_tx_lock. If np->intr_tx_reap
-is set, then access is permitted under spin_lock_irq(&np->lock).
-
-Thus configuration functions that want to access everything must call
- disable_irq(dev->irq);
- netif_tx_lock_bh(dev);
- spin_lock_irq(&np->lock);
-
-IV. Notes
-
-NatSemi PCI network controllers are very uncommon.
+recieve and transmit paths which are synchronised using a combination of
+hardware descriptor ownership, disabling interrupts and NAPI poll scheduling.

All right, then... I hadn't been sure if it's onboard-only, that's all.

Picked one for a fiver on ebay, just need to get around to putting it
into that U60 box and testing; not a problem, just hadn't got around to
doing that yet.

I applied it to #upstream (2.6.25) since forcedeth is not on any
big-endian platforms AFAIK.
Is it .24 material for some obvious reason, which I missed? :)

I have an epic100 card too if you need it (though it sounds like you
have something testable).

xircom_tulip_cb should probably be deleted, since it is the crappier of
the two drivers for the same hardware (xircom_cb being the other one).
xircom_cb _the driver_ is pretty odd. It is less like tulip than it
should be, actually. There are several things that could have been done
to improve the throughput/etc. of the driver, but it was more important
at the time to simply find a driver that always worked. IIRC its RX
filtering was broken, implying the need to enable promisc mode just to
receive packets normally.

Heh... FWIW, forcedeth patch (sent your way about two weeks ago) also
belongs in the same set. If you need a resend - tell...
There's another pile in drivers/net/wireless, but that's for linville to
forward when he gets around to it. Pure annotation patches belong to
past-2.6.24 merge.
I also have starfire and epic100 fixes, but that'll have to wait until
I get around to putting the cards into sparc box (mcast breakage for
starfire and full-driver one for epic100; since nobody had cared for
the latter since 2.3.late, well...)
I think I'll have an ipg fix for you tomorrow, but I want to RTFM first
to make sure that it makes sense. And there are several interesting
issues in atl1, netxen and cxgb3, but those will have to wait for when
I get around to asking maintainers just what the hell did they mean those
to do.
FWIW, drivers/net is fairly noise-free wrt sparse endianness warnings
in my tree; the main exceptions are prism54 (oid_mgt.c and the nightmares
it pulls) and skfp (AIX-shared vendor driver; 'nuff said, IMO).
BTW, if you still have any documentation for xircom_cb from your fighting
tulip-related stuff, it would be welcome - there are some oddities with
rx ring handling (assuming that we care about that driver at all and it's
not on the way out, that is).
