RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Rebase python-cryptography from 1.3.1 (RHEL 7.3) to 1.7. Version 1.7 hasn't been released yet. It's scheduled to be released in about two weeks (early December). The new version will contain two important fixes and a new feature for FreeIPA 4.5.

1.7 improvements:
* new osrandom engine in C (fix for SELinux execmem denials, fix for deadlock and segfaults in mod_wsgi subinterpreters) https://github.com/pyca/cryptography/pull/3229

1.6 improvements:
* new locking code in C (fixes same class of issues as osrandom engine) https://github.com/pyca/cryptography/pull/3226
* support for multi-valued RDNs https://github.com/pyca/cryptography/issues/3199

Tests are expected to be primarily SanityOnly, by testing IdM use cases only.

cryptography 1.7.1 was released a couple of hours ago, https://github.com/pyca/cryptography/releases/tag/1.7.1

1.7.1 has caused a regression in PyOpenSSL, https://github.com/pyca/cryptography/pull/3321 . I'm expecting to see a 1.7.2 release in a matter of days.

https://github.com/pyca/cryptography/pull/3321 affects only 1.8-dev. 1.7.1 is good to go.

We might want to wait for release 1.8 to get the fix for https://github.com/pyca/cryptography/pull/3382 . The PR replaces the last use of cffi callbacks in cryptography and fixes an issue with password protected private keys.

Verified using IPA version :: ipa-server-4.5.0-13.el7.x86_64


Quickinstall and other sanity testcases verifies the status of correct version of Python2-cryptography

# rpm -qa ipa-server python2-cryptography
ipa-server-4.5.0-13.el7.x86_64
python2-cryptography-1.7.2-1.el7.x86_64
