                                      optional data


V7:
Updated to patch cleanly with recent large commits.

Compiled and lightly tested.  Awaiting performance testing results.

Revised RCU spinlocks, based on review by Eric and Joe.

Trivial savings of 2 if tests, based on review by Joe.

Cosmetic changes to comment blocks, based on review by Eric.

Processing optional SYNACK data removed until later.


V6:
The new TCP_MSS_* symbols are now in an entirely separate patch.  Applied.

Updated and reorganized to split the code base into several pieces, as
requested by Eric.  No significant changes.

[net-next-2.6 PATCH v7 1/7 RFC] TCPCT part 1a: add request_values parameter for sending SYNACK

[William Allen Simpson]

[-- Attachment #1: Type: text/plain, Size: 1006 bytes --]

Add optional function parameters associated with sending SYNACK.
These parameters are not needed after sending SYNACK, and are not
used for retransmission.  Avoids extending struct tcp_request_sock,
and avoids allocating kernel memory.

Also affects DCCP as it uses common struct request_sock_ops,
but this parameter is currently reserved for future use.

Re: [net-next-2.6 PATCH v7 1/7 RFC] TCPCT part 1a: add request_values parameter for sending SYNACK

> +		goto drop_and_free;

Please fix the coding style here, the "||" belongs at the end
of the previous line, not at the start of the next one.

Also, since it will all fit one one line anyways, please make
it that way:

	if (tcp_v6_send_synack(sk, req, NULL) || want_cookie)

Some of us still use 80x25 terminals to read code :-)

I think you've been asked to fix this specific kinds of cases up
before.

Thanks a lot.

[net-next-2.6 PATCH v7 2/7 RFC] TCPCT part 1b: generate Responder Cookie secret

[William Allen Simpson]

[-- Attachment #1: Type: text/plain, Size: 876 bytes --]

Define (missing) hash message size for SHA1.

Define hashing size constants specific to TCP cookies.

Add new function: tcp_cookie_generator().

Maintain global secret values for tcp_cookie_generator().

This is a significantly revised implementation of earlier (15-year-old)
Photuris [RFC-2522] code for the KA9Q cooperative multitasking platform.

Linux RCU technique appears to be well-suited to this application, though
neither of the circular queue items are freed.

These functions will also be used in subsequent patches that implement
additional features.

So connection creation scalability will be limited now because
we'll always have to go through this centralized spinlock even
for independent listening sockets, right?

Just wondering...

I was about to complain about the same thing in a earlier version
of this patch kit, but then I noticed the spin lock aquiring 
is guarded by

if (unlikely(time_after_eq(jiffy, tcp_secret_generating->expires))) {

which presumably makes it rare enough?

Roughly once every 10 minutes.  In the original code with rw_lock()
that would have been more frequent on the read side, but the RCU
technique speeds that up considerably?

Also, not every listening socket, just sockets after a cookie option
arrives.  That will probably be only a few selected sockets, at least
for the time being.

[net-next-2.6 PATCH v7 3/7 RFC] TCPCT part 1c: sysctl_tcp_cookie_size, socket option TCP_COOKIE_TRANSACTIONS

[William Allen Simpson]

[-- Attachment #1: Type: text/plain, Size: 1190 bytes --]

Define sysctl (tcp_cookie_size) to turn on and off the cookie option
default globally, instead of a compiled configuration option.

Define per socket option (TCP_COOKIE_TRANSACTIONS) for setting constant
data values, retrieving variable cookie values, and other facilities.

Move inline tcp_clear_options() unchanged from net/tcp.h to linux/tcp.h,
near its corresponding struct tcp_options_received (prior to changes).

This is a straightforward re-implementation of an earlier (year-old)
patch that no longer applies cleanly, with permission of the original
author (Adam Langley):

    http://thread.gmane.org/gmane.linux.network/102586

These functions will also be used in subsequent patches that implement
additional features.

Requires:
   net: TCP_MSS_DEFAULT, TCP_MSS_DESIRED

I would prefer if the default did not depend upon whether
SYSCTL is enabled or not.  That's extremely non-intuitive.

This code was based on net/ipv4/tcp_minisocks.c for syncookies.
Apparently, default for syncookies has been controversial.

Would you accept always default to TCP_COOKIE_MAX?

The code already automatically reduces the size of the cookie to
match available space in the TCP options (part 1f).

Ok, here's what I'll push out to net-next-2.6, thanks again.

tcp: Don't make syn cookies initial setting depend on CONFIG_SYSCTL

That's extremely non-intuitive, noticed by William Allen Simpson.

And let's make the default be on, it's been suggested by a lot of
people so we'll give it a try.

Once again, for the umpteenth time, I learn that existing code
proves to be a bad example to follow....

Unlikely to break anything, according to studies of the subject:

         Medina, A., Allman, M., and Floyd, S., "Measuring Interactions
         Between Transport Protocols and Middleboxes", Proceedings 4th
         ACM SIGCOMM/USENIX Conference on Internet Measurement, October
         2004.  http://www.icsi.berkeley.edu/pubs/networking/tbit-
         Aug2004.pdf

TCPCT part 2 is much more likely to break things....

[net-next-2.6 PATCH v7 4/7 RFC] TCPCT part 1d: define TCP cookie option, extend existing struct's

[William Allen Simpson]

[-- Attachment #1: Type: text/plain, Size: 1860 bytes --]

Data structures are carefully composed to require minimal additions.
For example, the struct tcp_options_received cookie_plus variable fits
between existing 16-bit and 8-bit variables, requiring no additional
space (taking alignment into consideration).  There are no additions to
tcp_request_sock, and only 1 pointer in tcp_sock.

This is a significantly revised implementation of an earlier (year-old)
patch that no longer applies cleanly, with permission of the original
author (Adam Langley):

    http://thread.gmane.org/gmane.linux.network/102586

The principle difference is using a TCP option to carry the cookie nonce,
instead of a user configured offset in the data.  This is more flexible and
less subject to user configuration error.  Such a cookie option has been
suggested for many years, and is also useful without SYN data, allowing
several related concepts to use the same extension option.

    "Re: SYN floods (was: does history repeat itself?)", September 9, 1996.
    http://www.merit.net/mail.archives/nanog/1996-09/msg00235.html

    "Re: what a new TCP header might look like", May 12, 1998.
    ftp://ftp.isi.edu/end2end/end2end-interest-1998.mail

These functions will also be used in subsequent patches that implement
additional features.

Requires:
   TCPCT part 1a: add request_values parameter for sending SYNACK
   TCPCT part 1b: generate Responder Cookie secret
   TCPCT part 1c: sysctl_tcp_cookie_size, socket option TCP_COOKIE_TRANSACTIONS

Why not get the coding style correct wrt. long lines in patch #3 where
you initially added this function, rather than fixing it here as you
add the new ->cookie_plus assignment?

Documentation/SubmittingPatches at 619:

One significant exception is when moving code from one file to
another -- in this case you should not modify the moved code at all in
the same patch which moves it.  This clearly delineates the act of
moving the code and your changes.  This greatly aids review of the
actual differences and allows tools to better track the history of
the code itself.

[net-next-2.6 PATCH v7 5/7 RFC] TCPCT part 1e: implement socket option TCP_COOKIE_TRANSACTIONS

[William Allen Simpson]

[-- Attachment #1: Type: text/plain, Size: 868 bytes --]

Provide per socket control of the TCP cookie option and SYN/SYNACK data.

This is a straightforward re-implementation of an earlier (year-old)
patch that no longer applies cleanly, with permission of the original
author (Adam Langley):

    http://thread.gmane.org/gmane.linux.network/102586

The principle difference is using a TCP option to carry the cookie nonce,
instead of a user configured offset in the data.

Allocations have been rearranged to avoid requiring GFP_ATOMIC.

Requires:
   net: TCP_MSS_DEFAULT, TCP_MSS_DESIRED
   TCPCT part 1c: sysctl_tcp_cookie_size, socket option TCP_COOKIE_TRANSACTIONS
   TCPCT part 1d: define TCP cookie option, extend existing struct's

"?" should be at end of previous line not at beginning of

Eliding the repeated assertions, and focusing on this example.
This is not addressed (nor forbidden) in CodingStyle.

As Joe noted earlier with '?' and ':', there are ample examples
throughout the code base of this style, including here and there
among the tcp*.c files.  Obviously, this is very easy to read!

     Coding style is all about readability and maintainability
     using commonly available tools.

However, grep shows that the "||" or "&&" is elsewhere most often
indented 4 for each level (although there is some inconsistency).
Either 1, 2, or 4 distinguishes <condition> indentation from
<statements> indented by tab (8).

In my experience, I've found 1 best, as that lines up variables
and parentheses levels, and it's easy to type.  But it certainly
would be easy enough to indent by 2 or 4 instead.

BTW, the 'indent' program turns this into incomprehensible and
unmaintainable garbage.  Of course, there are ample examples of
garbage in these tcp*.c files, too.... :-(

Therefore, David, would indentation of 2 or 4 be preferable here?

Hi William.

I think the rather significantly majority style, especially
for net/... is to use || and && at the end of the line rather
than the start and it should be used.

Treewide:

$ grep -rP --include=*.[ch] "(\|\||\&\&)\s*$" * | wc -l
34180

$ grep -rP --include=*.[ch] "^\s*(\|\||\&\&)" * | wc -l
7855

net: 3859 to 382 (more than 10:1, so it's the one to follow)
drivers/net: 4610 to 666

Besides, it's the one David wants...

cheers, Joe

Thanks for measuring.

I'll note that during the previous review back at the v4 round, you
(Joe) passed along a formerly private message from Linus expressing his
preference for variable lvalues:

   http://www.spinics.net/lists/netdev/msg111212.html

But my example code in that thread also had both leading && and || -- and
neither David nor Eric nor Ilpo nor you mentioned that as an issue in that
entire thread:

   http://www.spinics.net/lists/netdev/msg111172.html

In the previous plaint about lvalues, there were merely 500+ examples
using the same constant lvalue form as my code -- in arch, drivers, net,
and sound.  For this example, many *thousands* are found everywhere!

Therefore, it's plain as can be that this is just more jumping through
arbitrary and capricious hoops that others are not required to follow.


> Besides, it's the one David wants...

At *thousands* of examples, including in the tcp*.c files themselves, it
really becomes obvious that that may be a personal preference of David,
but is *not* a tree-wide or even a net-wide coding style.

However, a private message to me nearly 2 months ago expressed:

   "As unpalatable as it may be, all the more reason to genuflect as
   required to get the changes into the net-next-2.6 tree so they will
   flow down to future distros."

I followed that advice for a month.  That last patch submitted for
inclusion was v4 on Oct 27th.  Then, as some have noticed, I quit using
the net-next tree for actual development.  I've only sent weekly RFC
versions to solicit more widespread comments from subject matter experts,
and keep the patch offsets in sync with the rapidly changing tree.

As a more recent private comment asked:

   "So your frustration is nothing but normal.  And guess what ? Few
   people accept the challenge, so keep trying !"

So, I'll try again now, with the assurance that this is the final hoop.

It seems similar kernel source uses are mostly historic.

Relatively little new code is added with leading || or &&.
There is some in staging/, but it normally gets removed.

Once more into the breach or men of few words are the best men?
I'll stop typing now...

Others, like Eric and Ilpo, don't have to jump through these hoops
because when they submit patches their code doesn't have coding
style issues like your's does.

Trust me, it's not about you, and you're not being picked out
specifically.  These things would be enforced upon anyone.  The only
unique aspect about you is that you seem to respond to these
requirements in the most sour manner possible rather than pleasantly
complying and thus getting your changes added to the tree.

It should be of the form:

	if (x &&
	    y)

or:
	if (x && y)

Fix patches, rather than complaints, for existing cases where things
do not follow this pattern are cetainly welcome.

Rather than playing with the dangling operator format which seems to be a coding
style that only David cares about. Why not go through and fix the really ugly old
drivers that need it. For a good horror experience, go look at the floppy driver.

net/... had the lower percentage of leading uses
and a maintainer that cared to standardize.

drivers/... has many odd uses of coding styles and
no single maintainer that cares much about style.

I've no desire to be floppy maintainer.  Do you?

[PATCH] drivers/block/floppy.c: stylistic cleanups

Just for you Stephen, here's a cleaned up version.
Now to see if it gets applied, which I rather doubt.

Changes:

Removed macro definitions and uses of
	IN, OUT, LAST_OUT, CLEARSTRUCT, and CHECK_RESET
Used C99 initializers
Removed assigns from if statements
Converted printks without KERN_ levels to pr_info and pr_cont
Removed unnecessary braces
Used print_hex_dump
Moved leading logical tests to end of previous line
Surrounded still ugly CALL and ECALL macro with do {} while (0)

Checkpatch complaints before:
total: 393 errors, 132 warnings, 4647 lines checked

after:
total: 1 errors, 11 warnings, 5352 lines checked

Compile tested only, x86 allyesconfig

so I'll put your cleanup in first.

[PATCH net-next-2.6] drivers/net: Move && and || to end of previous line

[Joe Perches]

Only files where David Miller is the primary git-signer.
wireless, wimax, ixgbe, etc are not modified.

Compile tested x86 allyesconfig only
Not all files compiled (not x86 compatible)

Added a few > 80 column lines, which I ignored.
Existing checkpatch complaints ignored.

Brice, I've made my objection known on the LKML.  Joe *agrees* that
having them on the beginning of the line is preferred.  Thousands of
contributors throughout the tree agree.

This is entirely a Miller thing.

My main objection to these sweeping patches is that it makes it much
more difficult to maintain and apply patches across different versions of
the tree.  We have already seen conflicts with other git maintained trees.

These patches should not be accepted to the main Linus tree.

This is not true.

I prefer code that I write for myself to
use leading continuation tests.

For the Linux code, as should be obvious
from the patches I submit, I prefer to
have adherence to one predominant majority
style.  I don't much care what form that
style actually takes.

> Thousands of

Nope.  There have been many efforts to
help standardize on single form styles.

I think you underestimate the value of
standardization and overestimate the
quantity of work to sort it out for
the -stable versions.

Actually, technically, legally etc. (except practically) William is right:
if it's not in the CodingStyle, and not obviously wrong, it shouldn't be
forced.

As I mentioned to somebody in private email (having kept rough track), it
took around 9 hours this week for my 8 patch series, spread over 3 days
because of the tedium.  Fix rejects, visually check patch against previous
version, compile, test -- at least 1/2 to 1 hour for each numbered patch.
Plus time to resubmit the patch series to the list again.

Of course, that was only for the initial patches already posted to the
list.  I've many more -- awaiting approval for the previous set....

Eventually, I have to do the same for each supported -stable version.

Multiply by thousands of contributors.

Hopefully, you did the same, carefully checking your regexp generated
patches visually line by line, and compiling, and testing every driver
in this large patch individually.

I'm not a big believer in making trivial formatting changes and assuming
they work.  Or that I didn't fumble fingers somehow.  I've made many such
stupid mistakes over the years.

You come out of nowhere as a new contributor.  You have to constantly
ask about policy and other formalities wrt. kernel development.

Yet here you are telling us what should or should not go into the
tree.

You don't even know what the "merge window" is yet you seem so
confident to elicit firm declarations about code policy.

That's nothing but blind arrogance.

Nobody can take you seriously William, really.

And if you think just omitting Joe's patch is going to make your
backporting work any easier, you're mistaken.

Every release we make tons and tons of cleanups and refactorizations
all over the networking and sometimes heavily in TCP.  So you're going
to run into such problems no matter whether Joe's patch goes in or
not.

And like Joe, I think you overstate  how much effort is involved
in such work.  Especially for the size of your patch.

And consider, how in the world do you think it is for me to have to
handle hundreds of patches per day from random people.  If anyone
should get the brunt of the pain, it's me.

Yet I'm ok with it, and you should be too.

That would be one of the questions (which git clone to patch against now)
that you haven't answered.  Silly of me to ask practical questions.

That would be because I've ample experience coding for multiple open
source platforms.  Apparently such experience isn't valued (by you).

But the fact that about 19% of the Linux code base has managed to function
for circa 18 years without this particular coding policy might be a clue!

Something that *is* in Documentation/ManagementStyle at 147:

     There's just a few simple rules here:
      (1) don't call people d*ckheads (at least not in public)
      (2) learn how to apologize when you forgot rule (1)

Might I suggest a look at Documentation/HOWTO and
Documentation/development-process/?  You might find that more of this
stuff is better documented than you think.  If there are gaps, please
let us know where they are, and we'll endeavor to fill them in.

Certainly better in general already but there is still some work to be 
done here as now you have an && only line. I guess it mostly has to do 
with comments but #if... blahblahs could be another type of failure (in 
automation like this).

The current form is

	if (foo 
#ifdef BAR
	    && bar
#endif
	   )

Another option could be:

#ifdef BAR
	if (foo && bar)
#else
	if (foo)
#endif

In any case, it won't be pretty.

But wouldn't your automation produce:

#ifdef BAR
	if (foo
#endif
	    &&
	    bar

? Like it did for the case where there was a comment between.

As I didn't go through the whole patch I don't know if there were in fact 
any #if things that got made into that kind of construct or not (just 
mentioned it that such places might also be affected incorrectly by your 
automation). I only noticed one of such after comment (ie., && on 
otherwise empty line) and hit reply.

[net-next-2.6 PATCH v7 6/7 RFC] TCPCT part 1f: Initiator Cookie => Responder

[William Allen Simpson]

[-- Attachment #1: Type: text/plain, Size: 615 bytes --]

Calculate and format <SYN> TCP_COOKIE option.

This is a significantly revised implementation of an earlier (year-old)
patch that no longer applies cleanly, with permission of the original
author (Adam Langley):

    http://thread.gmane.org/gmane.linux.network/102586

Requires:
   TCPCT part 1c: sysctl_tcp_cookie_size, socket option TCP_COOKIE_TRANSACTIONS
   TCPCT part 1d: define TCP cookie option, extend existing struct's

Please put the "?" and ":" and the end of the previous line not
at the beginning of the next one.
>  
> +	if (*md5 == NULL
> +	 && (OPTION_TS & opts->options)
> +	 && cookie_size > 0) {

Please fix up the coding style of this conditional.  The '&&'
belongs at the end of the previous line and the indentation is
not correct here.

Thanks.

[net-next-2.6 PATCH v7 7/7 RFC] TCPCT part 1g: Responder Cookie => Initiator

[William Allen Simpson]

[-- Attachment #1: Type: text/plain, Size: 1269 bytes --]

Parse incoming TCP_COOKIE option(s).

Calculate <SYN,ACK> TCP_COOKIE option.

Send optional <SYN,ACK> data.

This is a significantly revised implementation of an earlier (year-old)
patch that no longer applies cleanly, with permission of the original
author (Adam Langley):

    http://thread.gmane.org/gmane.linux.network/102586

Requires:
   TCPCT part 1a: add request_values parameter for sending SYNACK
   TCPCT part 1b: generate Responder Cookie secret
   TCPCT part 1c: sysctl_tcp_cookie_size, socket option TCP_COOKIE_TRANSACTIONS
   TCPCT part 1d: define TCP cookie option, extend existing struct's
   TCPCT part 1e: implement socket option TCP_COOKIE_TRANSACTIONS
   TCPCT part 1f: Initiator Cookie => Responder
