[Message part 1 (text/plain, inline)]
Source: dnspython
Version: 2.7.0-1
Severity: serious

Dear maintainer(s),

With a recent upload of dnspython the autopkgtest of dnspython fails in 
testing when that autopkgtest is run with the binary packages of 
dnspython from unstable on s390x. It passes when run with only packages 
from testing. In tabular form:

                       pass            fail
dnspython              from testing    2.7.0-1
all others             from testing    from testing

I copied some of the output at the bottom of this report.

Currently this regression is blocking the migration to testing [1]. Can 
you please investigate the situation and fix it?

[Message part 1 (text/plain, inline)]
Hi Paul,

I have been looking at this issue for the past few days. Thanks for this valuable information.
When run parallelly on an x86 machine and an s390x machine I was able to see that an encoding to byte string varied at an encode function call from pylsqpack.
Since it was a wrapper to a C function PDB was not able to step into that particular function call and see what is happening under the hood.
I am still checking for ways to debug that properly.

Thanks
Pranav

Subject: [EXTERNAL] Bug#1099935: dnspython: autopkgtest regression on s390x: bad request

Source: dnspython
Version: 2.7.0-1
Severity: serious
User: debian-ci@lists.debian.org
Usertags: regression
User: debian-s390@lists.debian.org
Usertags: s390x

Dear maintainer(s),

With a recent upload of dnspython the autopkgtest of dnspython fails in
testing when that autopkgtest is run with the binary packages of
dnspython from unstable on s390x. It passes when run with only packages
from testing. In tabular form:

                        pass            fail
dnspython              from testing    2.7.0-1
all others             from testing    from testing

I copied some of the output at the bottom of this report.

Currently this regression is blocking the migration to testing [1]. Can
you please investigate the situation and fix it?

Hi Paul,

I have been looking at this issue for the past few days. Thanks for this valuable information.
When run parallelly on an x86 machine and an s390x machine I was able to see that an encoding to byte string varied at an encode function call from pylsqpack.
Since it was a wrapper to a C function PDB was not able to step into that particular function call and see what is happening under the hood.
I am still checking for ways to debug that properly.

Thanks
Pranav

Subject: [EXTERNAL] Bug#1099935: dnspython: autopkgtest regression on s390x: bad request

Source: dnspython
Version: 2.7.0-1
Severity: serious
User: debian-ci@lists.debian.org
Usertags: regression
User: debian-s390@lists.debian.org
Usertags: s390x

Dear maintainer(s),

With a recent upload of dnspython the autopkgtest of dnspython fails in
testing when that autopkgtest is run with the binary packages of
dnspython from unstable on s390x. It passes when run with only packages
from testing. In tabular form:

                        pass            fail
dnspython              from testing    2.7.0-1
all others             from testing    from testing

I copied some of the output at the bottom of this report.

Currently this regression is blocking the migration to testing [1]. Can

[Message part 1 (text/plain, inline)]
Hi Paul,

I am still continuing my search on the issue.
It seems that the issue is rising from pylsqpack.
When the value field in the packet header for HTTP3 GET request contains
long strings there are problems while encoding (Only in s390x).
Due to this one of the GET parameters gets jumbled and this results in a bad request.
I am not able to see the same issue on ls-qpack though.
I will update any new findings.

Thanks,
Pranav

Hi Paul,

I have been looking at this issue for the past few days. Thanks for this valuable information.
When run parallelly on an x86 machine and an s390x machine I was able to see that an encoding to byte string varied at an encode function call from pylsqpack.
Since it was a wrapper to a C function PDB was not able to step into that particular function call and see what is happening under the hood.
I am still checking for ways to debug that properly.

Thanks
Pranav

Source: dnspython
Version: 2.7.0-1
Severity: serious
User: debian-ci@lists.debian.org
Usertags: regression
User: debian-s390@lists.debian.org

Dear maintainer(s),

With a recent upload of dnspython the autopkgtest of dnspython fails in
testing when that autopkgtest is run with the binary packages of
dnspython from unstable on s390x. It passes when run with only packages
from testing. In tabular form:

                        pass            fail
dnspython              from testing    2.7.0-1
all others             from testing    from testing

I copied some of the output at the bottom of this report.

Currently this regression is blocking the migration to testing [1]. Can
you please investigate the situation and fix it?

[Message part 1 (text/plain, inline)]
Hi Paul,

I am still continuing my search on the issue.
It seems that the issue is rising from pylsqpack.
When the value field in the packet header for HTTP3 GET request contains
long strings there are problems while encoding (Only in s390x).
Due to this one of the GET parameters gets jumbled and this results in a bad request.
I am not able to see the same issue on ls-qpack though.
I will update any new findings.

Thanks,
Pranav

Hi Paul,

I have been looking at this issue for the past few days. Thanks for this valuable information.
When run parallelly on an x86 machine and an s390x machine I was able to see that an encoding to byte string varied at an encode function call from pylsqpack.
Since it was a wrapper to a C function PDB was not able to step into that particular function call and see what is happening under the hood.
I am still checking for ways to debug that properly.

Thanks
Pranav

Source: dnspython
Version: 2.7.0-1
Severity: serious
User: debian-ci@lists.debian.org

Dear maintainer(s),

With a recent upload of dnspython the autopkgtest of dnspython fails in
testing when that autopkgtest is run with the binary packages of
dnspython from unstable on s390x. It passes when run with only packages
from testing. In tabular form:

                        pass            fail
dnspython              from testing    2.7.0-1
all others             from testing    from testing

I copied some of the output at the bottom of this report.

Currently this regression is blocking the migration to testing [1]. Can
you please investigate the situation and fix it?

Yes, I was just going through this today (I hadn't noticed your emails 
until after I'd spent some time on it) and I found much the same thing.  
I reduced it to the following more manageable test case:

  # amd64
  >>> import pylsqpack
  >>> encoder = pylsqpack.Encoder()
  >>> decoder = pylsqpack.Decoder(4096, 16)
  >>> _, frame = encoder.encode(0, [(b':path', b'/dns-query?dns=AAABAAABAAAAAAAAAAABAAABAAAAAAAAA2RucwZnb29nbGUAAAEAAQ')])
  >>> decoder.feed_header(0, frame)
  (b'', [(b':path', b'/dns-query?dns=AAABAAABAAAAAAAAAAABAAABAAAAAAAAA2RucwZnb29nbGUAAAEAAQ')])

  # s390x
  >>> import pylsqpack
  >>> encoder = pylsqpack.Encoder()
  >>> decoder = pylsqpack.Decoder(4096, 16)
  >>> _, frame = encoder.encode(0, [(b':path', b'/dns-query?dns=AAABAAABAAAAAAAAAAABAAABAAAAAAAAA2RucwZnb29nbGUAAAEAAQ')])
  >>> decoder.feed_header(0, frame)
  (b'', [(b':path', b'd/snq-euyrd?snA=AAABAAABAAAAAAAAAAABAAABAAAAAAAAR2cuZwbn92bnUGAAAEAAQ')])

How does the attached patch look?  The basic problem is that the Huffman 
encoder was assuming little-endian when reading from the source buffer.

I realize this is against vendored code, but upstream ls-qpack seems to 
have pretty much the same code in this area, so if this looks good I'll 
tidy it up and submit it there.

Thanks,

[Message part 1 (text/plain, inline)]
In a file called huff-tables.h in ls-qpack, some calculations where happening based on the following code:
#if __BYTE_ORDER == __LITTLE_ENDIAN
#define I(i,j) ((j<<8)|i)
#else
#define I(i,j) ((i<<8)|j)
#endif
Surprisingly when compiled with the c99 standards the #else part was getting executed while for gnu99 #if part was getting triggered.
Writing some #ifdef statements it was found that __BYTE_ORDER and __LITTLE_ENDIAN were not defined when compiled with c99 and hence the macro evaluated to
#if NULL == NULL
which caused the little endian logic of the code to get executed.
In little endian systems, this would not be an issue as either ways only little endian part of the logic will get executed.
__BYTE_ORDER and __LITTLE_ENDIAN are defined in the header file endian.h in glibc.
This header file is automatically included when compiling with gnu99 and not when compiling with c99(This was tested by preprocessing with both c99 and gnu99 with the -E flag passed to gcc).
In the setup.py file of pylsqpack it is mentioned to adhere to c99 standards.
So, adding <endian.h> header file to lsqpack.c file seems to fix the issue.
Please see if the attached patch is fine. I also am not aware of how to submit a patch. So, if the attached patch is all good, can you please guide me on how to submit the patch.

Also, thanks Colin for the patch.
I tested that out. But it failed with -std=gnu99 and hence I ran the ls-qpack's test cases, and it failed there as well (Because ls-qpack is compiling without passing any -std flags which defaults to gnu standards).

Thank you

Ah yes, of course.  In the circumstances I think that's better than my 
patch, which I think would have broken (due to overcorrection) if 
<endian.h> happened to be included by something else.

>Please see if the attached patch is fine. I also am not aware of how to submit a patch. So, if the attached patch is all good, can you please guide me on how to submit the patch.

I think the best way to go is to send this as a pull request to 
https://github.com/litespeedtech/ls-qpack, and then figure out how to 
get pylsqpack upgraded upstream (though I can apply the patch to the 
Debian package, at least).

If you can make a pull request yourself, then that would be best, but I 
can send it upstream on your behalf if you aren't set up for that.  
Could you at least write a short commit message for your patch, and 
reference https://bugs.debian.org/1099935 somewhere in it for tracking 
purposes?

Thanks,

Hi Colin,

Thanks a lot. I raised an issue with a suggested fix on pylsqpack's github repo and has
asked them how they want to integrate the changes. I will also raise a PR to ls-qpack's
repo. Meanwhile, I am attaching the patch with a commit message generated via quilt.
I am new to the community so please feel free to share if something is to be modified.

This attachment wasn't an email attachment - it was some kind of 
Sharepoint link that I can't access.  Could you please resend your 
attachment as an actual email attachment, and then I can get it
into the Debian pylsqpack package?

Alternatively, pointing me at your ls-qpack PR once it exists would be 
fine too - I don't see anything there yet.

Thanks,
