[PATCH 0/3] Disable OpenSSL and Python3-cryptography legacy features by default

[PATCH 0/3] Disable OpenSSL and Python3-cryptography legacy features by default

[Colin Pinnell McAllister]

TLS 1.0 and 1.1 have been deprecated by the IETF since 2021, and
OpenSSL's legacy module contains deprecated and unmaintained components.
This series disables legacy support by default in both OpenSSL and
python3-cryptography, requiring users to explicitly opt-in if needed.

The first two patches add packageconfig options to control legacy TLS
protocol support and the legacy OpenSSL module. The final patch aligns
python3-cryptography with the new OpenSSL defaults.

Note that the TLS 1.0/1.1 changes replace the existing "no-tls1" and
"no-tls1_1" packageconfig options with affirmative "tls1" and "tls1_1"
options that are disabled by default. While less disruptive to enable
the "no-*" options by default, using affirmative options provides
consistency with the new "legacy" option and is clearer than having
default-enabled "no-*" options.

Testing performed:
* Verified both recipes build successfully with and without the new
  options
* Ran OpenSSL ptests with legacy enabled/disabled and TLS 1.0/1.1
  disabled
* Ran python3-cryptography ptests with legacy-openssl disabled
* Confirmed ptests correctly skip tests for disabled legacy features

[PATCH 2/3] openssl: Add legacy packageconfig option

[Colin Pinnell McAllister]

Add packageconfig option to enable legacy support (disabled by default).
The legacy module includes deprecated and unmaintained OpenSSL
components. The openssl-ossl-module-legacy package that includes the
module is now conditional on the packageconfig option being enabled.
Packages that depend on this package are also now conditional on the
packageconfig option.

Hi Colin,

Thanks for your patch.

It looks like we are having some ptest failing on the autobuilder:

Failed ptests:
{'python3': ['test_min_max_version', 'python3']}

https://autobuilder.yoctoproject.org/valkyrie/#/builders/73/builds/3075
https://autobuilder.yoctoproject.org/valkyrie/#/builders/61/builds/3030

Test logs can be found here:

https://valkyrie.yocto.io/pub/non-release/20260212-56/testresults/qemuarm64-ptest/core-image-ptest-python3/

Can you have a look at this error?

Hi Mathieu,

The test_min_max_version test in Python 3.14 test_ssl.py is failing because
of my patch that disables TLS 1 and 1.1 by default.

One of the assertions in the test_min_max_version checks if the minimum
supported TLS version is either TLS v1, TLS v1.1, or SSL v3. With TLS v1
and TLS v1.1 disabled, the minimum version is now TLS v1.2, which is not
included in that set. If I add TLS v1.2 to the set, test_min_max_version
passes.

This seems like something I can patch upstream in cpython so I will start
that process. I think it's ideal to disable all of these packageconfig
options by default together. So in my opinion it would be best to put my
patches on hold until this issue with cpython is fixed. I'm also open to
discussing short term solutions.

Thanks,

There should be no reason to conditionally add the 
${PN}-ossl-module-legacy package here. If the legacy PACKAGECONFIG 
is not enabled, then I assume that no files that go in this package 
are created and thus the package will not be created even if it is 
listed in PACKAGES.

Since this is a recommendation, there is no reason to make it 
conditional as long as the package is listed in PACKAGES. If there 
are no files in the package and it thus is not created, then the 
recommendation will just be ignored.

Turn this into a recommendation instead and then there 
is no longer any need for it to be conditionally added.

[PATCH v2 0/4] Disable OpenSSL and Python3-cryptography legacy features by default

[Colin Pinnell McAllister]

TLS 1.0 and 1.1 have been deprecated by the IETF since 2021, and
OpenSSL's legacy module contains deprecated and unmaintained components.
This series disables legacy support by default in both OpenSSL and
python3-cryptography, requiring users to explicitly opt-in if needed.

The first two patches add packageconfig options to control legacy TLS
protocol support and the legacy OpenSSL module. The final patch aligns
python3-cryptography with the new OpenSSL defaults.

Note that the TLS 1.0/1.1 changes replace the existing "no-tls1" and
"no-tls1_1" packageconfig options with affirmative "tls1" and "tls1_1"
options that are disabled by default. While less disruptive to enable
the "no-*" options by default, using affirmative options provides
consistency with the new "legacy" option and is clearer than having
default-enabled "no-*" options.

V2 changes:
* Added a backport of the TLS test fix from GH-144790 to fix test
  failures with TLS 1.2 as the minimum version when TLS 1.0 and 1.1 are disabled.
* Updated TLS patch commit message to be more clear as "1.x" could also
  apply to TLS 1.2/1.3
* Removed conditional logic to add the legacy package based on the
  packageconfig setting
* Moved OpenSSL legacy package to an rrecommends for libcrypto and
  ptests

Testing:
* For OpenSSL legacy package:
  ptests ran: openssl and python3-cryptography
  * legacy enabled, legacy-openssl disabled: Builds and ptests pass
  * legacy enabled, legacy-openssl enabled: Builds and ptests pass
  * legacy disabled, legacy-openssl enabled: Build fails as expected,
    with "Nothing provides openssl-ossl-module-legacy"
  * legacy disabled, legacy-openssl disabled: Builds and ptests pass
* For TLS 1.0/1.1 changes:
  ptests ran: openssl and python3
  * tls1 disabled, tls1_1 disabled: Builds and ptests pass
  * tls1 disabled, tls1_1 enabled: Builds and ptests pass
  * tls1 enabled, tls1_1 disabled: Builds and ptests pass
  * tls1 enabled, tls1_1 enabled: Builds and ptests pass

Disables support by default in packageconfig, requiring users to
explicitly opt-in for these deprecated protocols.

[PATCH v2 3/4] openssl: Add legacy packageconfig option

[Colin Pinnell McAllister]

Add packageconfig option to enable legacy support (disabled by default).
The legacy module includes deprecated and unmaintained OpenSSL
components. Drops openssl-oss-module-legacy from a runtime depends to a
runtime recommends for ptest.

v2 changes:
* Removed conditional logic to add the legacy package based on the
  packageconfig setting
* Moved ossl-module-legacy back to an rrecommends for libcrypto
* Moved ossl-module-legacy to an rrecommends for ptests instead of an
  rdepends

Hi Colin,

Thanks for the new version.

I believe we have a new error:

Can you have a look at the issue?

My bad, the issue probably comes from another patch. This series is
probably good.

Thanks,
