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.

Description Alicja Kario 2019-06-07 12:29:22 UTC
Description of problem:
NSS will reply with internal_error when the signature algorithms or certificate selected can't be used with negotiated protocol version

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. setup server that asks in CertificateRequest message only for rsa_pkcs1_* signature algorithms
2. connect with nss client with rsa certificate
3.

Actual results:
internal_error sent

on client side:
tstclnt: connect: PR_IN_PROGRESS_ERROR: Operation is still in progress (probably a non-blocking connect)
tstclnt: about to call PR_Poll for connect completion!
tstclnt: PR_Poll returned 0x02 for socket out_flags.
tstclnt: ready...
tstclnt: about to call PR_Poll !
tstclnt: PR_Poll returned!
tstclnt: PR_Poll returned 0x00 for stdin out_flags.
tstclnt: PR_Poll returned 0x01 for socket out_flags.
tstclnt: PR_Poll returned 0x01 for socket out_flags.
tstclnt: Read from server -1 bytes
tstclnt: about to call PR_Poll !
tstclnt: PR_Poll returned!
tstclnt: PR_Poll returned 0x00 for stdin out_flags.
tstclnt: PR_Poll returned 0x01 for socket out_flags.
tstclnt: PR_Poll returned 0x01 for socket out_flags.
tstclnt: Read from server -1 bytes
tstclnt: about to call PR_Poll !
tstclnt: PR_Poll returned!
tstclnt: PR_Poll returned 0x00 for stdin out_flags.
tstclnt: PR_Poll returned 0x01 for socket out_flags.
tstclnt: PR_Poll returned 0x01 for socket out_flags.
tstclnt: using asynchronous certificate validation
tstclnt: Read from server -1 bytes
tstclnt: read from socket failed: SEC_ERROR_LIBRARY_FAILURE: security library failure.
tstclnt: exiting with return code 1

Expected results:
handshake_failure

Additional info:
Upstream analysis (MZBZ#1552254) indicates that the way NSS processes client certificates is problematic in general - thus the subject.
