I agree.

Well, I think that 2.2.24 and 2.2.25 kernels are really stable (at least on
UP), but that the most weak side is on IDE disk drivers.

They seem to have DMA problems when using recent hard disks (i.e. Maxtor,
etc.)
that lead to serious file system corruption problems.

Maybe there are also geometry problems because all troubles have been
observed
on disks with more than 32 GB of capacity (i.e. 40 GB).

This is a pity because, up to now, 2.2.x kernels have been
a valid choice for small / semi-embedded systems 80x86
(yes, I know that 2.4 should be better, but I'm still waiting for
 a stable rock kernel).

In conclusion, I hope that next maintainer will think about
these matters:
	IDE drivers;
	security fixes;
	micro-optimizations;
	compatibility with newer compilers.

After all if 2.0 seems to be still alive also 2.2 should be.

My -secure tree is also rock solid on SMP :p

I agree on this. Therefore my 2.2-secure tree has a 2.4 IDE backport from the 
PLD Project by Krzysiek Taraszka & Krzysiek Oledzki. It's not that up2date 
like .21 and .22 IDE code is, but it works very very smooth and nice and rock 
solid. We use the 2.2-secure tree for almost all customers in my company. 
Biggest harddisk is a 160GB Maxtor IDE disk.

ack!

ack! Current 2.2 is missing, for example, hashing exploits in network stack, 
like 2.4 had some time ago.

also done in 2.2-secure

This might be the hardest job. This is not done in 2.2-secure. I think the 
effort in doing this is not worth the time it takes.

I agree 100%. Anyway, no comment from Alan, so I think he don't want to give 
2.2 away to me.

P.S.: I've cc'ed Ruben, Alan and Ville.

The problem is that change breaks stuff. a lot of the 2.2 users will
happily trade lack of LBA48 support for stability and predictability.
Thats why I took a basically "if its not a serious bugfix its not going
in" approach

As a 2.2 user, I have to agree with this sentiment.

Just as Rome wasn't built in a day, 2.2 didn't get as stable as it is
overnight.  Unfortunately, any change now risks subtley destabilizing 2.2
for some obscure case somewhere.  Such destabilization could literally
happen overnight {:-(

OTOH, some users may find that the stability of 2.2 combined with some
other feature(s) (be it LBA48/IPSec/whatever (in my case it's MPPE from
-secure + a timer hack)) works just fine for them.

I.e. we can be well-served by a very stable "official" 2.2 tree which is
supplemented by the likes of MCP's -secure patchset, and others.

Perhaps the middle ground is to keep the 2.2 kernel pretty much as-is
(modulo bugfixes) and include pointers to optional patch(sets)?  That's
certainly more palatable than people maintaining patch-reversions to
retain their stability!

Worse still, as is too often the case, feature updates may provoke some
2.2 users to NOT upgrade (and hence miss security fixes) lest they
compromise stability.

HTH and many thanks for your contributions,
Neale.

Yeah, I agree with you. Anyway, I've never said I will integrate that IDE 
stuff when I become the 2.2 maintainer :) ... I just said I'll think about it 
;) ... I never ever want to break 2.2, and such an update will definitively 
break things. 2.2 took a long time to become that stable like it is now and it 
can be broke within minutes. A no-go!

For users who need/want/experiment with that stuff there is still my 
2.2-secure tree.

Anyway, 2.2 needs the hashing exploit fix ASAP ;)

And they still use something like 2.2.12 which has a few remote exploits. ;)

What's up with linux-2.2 now? Who will do Alan's job in the next year?

Marc is intrested doing this job. I know Marc from linux-2.2.x-secure
and from the wolk project, see http://wolk.sourceforge.net. Why not
Marc? He can surely differentiate between mainstream and a private kernel fork
tree. Or do you think, Marc will merge every single bit out of his kernel tree
into mainstream? I bet he won't 

I can't see postings from other people who want to take 2.2.

I think 2.2 is not dead. I often see 2.2 kernels running on systems like
wlan access points or dsl routers from different vendors. 2.2 is often
used where stability is a must-have. At least security fixes have to go in.

What do you think?
