It's just a consistency thing.
It identifies code where MAC addresses are used.
an allyesconfig is a bit smaller (~.1%).
pr_debug is a noop when not debugging, print_mac is optimized away.

Yes, SYSFS_DEPRECATED is enabled. And the init scripts are from Fedora 8.

There was a bug (fixed in 2.6.24) that had to do with sysfs_create_link
and SYSFS_DEPRECATED probably there is a similar problem with directories.

Reading a serie of zero from the cmos sram area do not work
well with is_valid_ether_addr(). Let's read the mac address
from the eeprom first as it seems more reliable.

That solved it.
I wonder if that's also why modprobe tends to wedge up with the new USB announce thingy... Tomorrow's debugging will tell.

We converted the entire tree over the print_mac(), and since
the MAC_FMT stuff was therefore no longer used we could
remove it.
Some references slipped back in somehow, and thus MAC_FMT
did too.
There is no reason to keep around a global interface for
_one_ user when that user can use the recommended interface
just as equally as the rest of the tree which we converted.
This is a pr_debug() statement we're talking about here.

The way pr_debug is implemented it still results in two function
calls per packet since the compiler doesn't know that it doesn't
have visible side-effects besides modifying the (unused) buffer.
I confirmed this using codiff.

Unfortunately the ISP's syslog stops. But I've been able to borrow two Quad Xeon boxes and have reproduced the problem.
Here's a new version of the patch. The patch avoids disabling irqs and fixes the sk_dst_get() usage that DaveM mentioned. But even with this patch, lockdep still complains if hundreds of ppp sessions are inserted into a tunnel as rapidly as possible (lockdep trace is below). I can stop these errors by wrapping the call to ppp_input() in pppol2tp_recv_dequeue_skb() with local_irq_save/restore. What is a better fix?
btw, I'm not sending this from my usual mail client so the patch will probably be mangled; I'm sending it only for feedback / discussion at this stage.

* Re: [PATCH 1/3] Support arbitrary initial TCP timestamps

Yes, I was worried that would be deemed too high of a cost, but it was
the most efficient way I could think to accomplish what I wanted.

That would work fine if my mine purpose was to randomize the tcp
timestamp to mitigate the leak in information regarding uptime, but
despite the brief description, that's only a side effect of what I
intended to do. What I wanted was a way to be able to choose an initial
tcp timestamp for a particular connection that was not tied directly to
jiffies.
The two patches following this show my intended use case. I intend to
enhance syncookie support to allow it to support advanced tcp options
(sack and window scaling). Normally syncookies encode the bare minimum
state of a connection in the ISN they choose, but the 32bit ISN isn't
enough to encode advanced tcp options so you are left with a working but
crippled tcp stack during a synflood attack. If in addition to choosing
an ISN we are able to choose an initial tcp timestamp, we are then able
to encode an additional 32 bits of information that can contain more of
the advanced tcp options.
This stems from a discussion about implementing IPv6 support for
syncookies, and the main concern being that syncookies disabled too many
valuable tcp features to be relevant on modern systems. Many people
stood in opposition to that statement, but it did not seem as though a
general consensus was reached. http://lkml.org/lkml/2008/2/4/396
I'm always open to alternatives.

* TG3 network data corruption regression 2.6.24/2.6.23.4
From: Tony Battersby @ 2008-02-18 22:41 UTC (permalink / raw)
To: Michael Chan, Herbert Xu, David S. Miller, netdev
Cc: Greg Kroah-Hartman, linux-kernel
I am experiencing network data corruption with a 3Com 3C996B-T NIC
(Broadcom NetXtreme BCM5701; driver tg3.ko). I have identified the
following patch as the trigger:
commit fb93134dfc2a6e6fbedc7c270a31da03fce88db9
Author: Herbert Xu <herbert@gondor.apana.org.au>
Date: Wed Nov 14 15:45:21 2007 -0800
[TCP]: Fix size calculation in sk_stream_alloc_pskb
We round up the header size in sk_stream_alloc_pskb so that
TSO packets get zero tail room. Unfortunately this rounding
up is not coordinated with the select_size() function used by
TCP to calculate the second parameter of sk_stream_alloc_pskb.
As a result, we may allocate more than a page of data in the
non-TSO case when exactly one page is desired.
In fact, rounding up the head room is detrimental in the non-TSO
case because it makes memory that would otherwise be available to
the payload head room. TSO doesn't need this either, all it wants
is the guarantee that there is no tail room.
So this patch fixes this by adjusting the skb_reserve call so that
exactly the requested amount (which all callers have calculated in
a precise way) is made available as tail room.

This patch was included in 2.6.24 and 2.6.23.4 -stable. I am
experiencing data corruption with kernels 2.6.23.4 - 2.6.23.16, 2.6.24 -
2.6.24.2, and 2.6.25-rc2-git1. I have verified that reverting the above
patch (by hand) makes the data corruption go away on all affected
kernels (note that in 2.6.25 the function is sk_stream_alloc_skb() in
net/ipv4/tcp.c rather than sk_stream_alloc_pskb() in include/net/sock.h).
(Also note that when testing 2.6.23 - 2.6.23.4, I had to apply the
individual patch "TG3: Fix performance regression on 5705." from 2.6.23.5.)
I do not get data corruption when substituting a SysKonnect 9D21 NIC
(which also uses the tg3.ko driver) or a Intel PRO/1000 82546GB NIC
(which uses the e1000.ko driver).
In addition to the 3Com NIC, my computer has a SCSI HBA with an attached
tape drive. The network data corruption happens only when reading from
or writing to the tape drive. I have tried both a LSI MPT Fusion
Ultra320 SCSI HBA (mptspi.ko) and a LSI 53c1010 Ultra160 HBA
(sym53c8xx.ko) with the same results. The NIC and SCSI HBA are on
separate PCI-X buses and do not share IRQs. I am using two completely
separate test programs to access the SCSI tape drive and test network
data integrity, so one would expect no interaction between the two tests
other than CPU scheduling and DMA bandwidth. There is no disk I/O
generated by either test program.
The test program that I am using to debug this problem does the following:
Computer A (kernel 2.6.24.2; 3Com 3C996B-T NIC):
malloc a 64 KB buf aligned to a 4 KB boundary
loop {
fill 64 KB buf with count data pattern
send(64 KB, MSG_MORE) <--- eventually sends corrupted data
}
(SCSI tape drive test program runs separately in the background)
Computer B (kernel 2.6.12):
malloc a 64 KB buf aligned to a 4 KB boundary
loop {
recv(64 KB, MSG_WAITALL)
verify count data pattern in 64 KB buf
}
After running for a few seconds, the verify on computer B detects data
corruption in the last 4 bytes of the 64 KB buffer. The last 48 bytes
of the corrupted 64 KB buffer look like this:
D0 D1 D2 D3 | D4 D5 D6 D7 | D8 D9 DA DB | DC DD DE DF
E0 E1 E2 E3 | E4 E5 E6 E7 | E8 E9 EA EB | EC ED EE EF
F0 F1 F2 F3 | F4 F5 F6 F7 | F8 F9 FA FB | F4 F5 F6 F7
The last 4 bytes should be "FC FD FE FF" but instead are corrupted to
"F4 F5 F6 F7", a sequence which came earlier in the data stream. The
data corruption always occurs at this same buffer offset and with the
same 4 earlier bytes duplicated. However, it occurs on a different
iteration of the send()/recv() loop each time the test is run.
When I reverse the test so that Computer A does recv() and Computer B
does send(), the test passes with no data corruption. Therefore, it
appears that the data corruption happens on send() but not recv().
The motherboard that I am using is a Commell LV-672. This motherboard
has a PCI-express x16 slot but no PCI-X slots. To plug in the PCI-X NIC
and SCSI HBA, I am using a SuperMicro CSE-RR2UE-AX riser card which
plugs into the PCI-express slot on the motherboard and provides 3 PCI-X
slots (two slots together on one PCI-X bus and one slot on its own PCI-X
bus). The data corruption happens with every combination of the 2 cards
in the 3 slots.
I assume that the above patch is just exposing some way in which the tg3
driver or the BCM5701 chip are broken. For now, I am just reverting the
above patch for kernels that I use until a better solution is
forthcoming. I expect that this problem will be difficult for other
developers to reproduce, but I can test any patches that anyone wants to
send me. [ In the meantime, should we revert the patch for 2.6.23.x and
2.6.24.x -stable, or wait for a fix to tg3? ]
I am not sure if it is relevant, but I am also getting the following
messages sometimes during testing:
Clocksource tsc unstable (delta = 64002086 ns)
Time: pit clocksource has been installed.
This seems bogus because the CPU is a Intel Pentium 4 with
HyperThreading, so the tsc should be reliable.

Hmm... This is a really long report and quite a bit different from
the previous one. I need some time for this. BTW: you sent before a
lockdep report with hlist_lock problem. I think this could be fixed
in some independent patch to make this all more readable. Are all
the other changes in this current patch only because of this or
previous lockdep report or for some other reasons (or reports) yet?

I've posted a series of patches that I believe address Andi's concerns
about syncookies not supporting valuable tcp options (primarily SACK,
and window scaling). The premise being if the client support tcp
timestamps we can encode the additional tcp options in the initial
timestamp we send back to the client, and they will be echo'd back to us
in the ack. Anyone interested have a look, and provide any suggestions
you may have. The new patches are a superset of this patch, so if they
are accepted this is one obsolete.

One consequence of Herbert's change is that the chip will see a
different datastream. The initial skb->data linear area will be
smaller, and the transition to the fragmented area of pages will be
quicker.

That's a bug.
I think we can fix this easily by using __attribute_const_
on the print_mac() declaration. Let me play with that.

Actually it seems the 'pure' attribute is more important
here. Although it's not semantically a perfect match,
what we need to tell the compiler is basically that:
1) the return value depends upon the inputs
2) if the input is not used, it's safe to avoid the call
and 'pure' accomplishes that without any unwanted side-effects.
I think this will not result in any unwanted over-optimization.
Because if the inputs change in any way GCC has to emit the
call.
Any objections?

[NET]: Elminate spurious print_mac() calls.
Patrick McHardy notes that print_mac() can get invoked
even if the result it unused (f.e. as an argument to
pr_debug() when DEBUG is not defined).
Mark this function as "__pure" to eliminate this problem.

I see. Perhaps when we get to the end of the data-stream, there is a
tiny frag that the chip cannot handle. That's the only thing I can
think of.
Please try this patch to see if the problem goes away. This will
disable SG on 5701 so we always get linear SKBs.
