Notifications not being sent with warning "error:060800A3:digital envelope routines:EVP_DigestInit_ex:disabled for fips"

Reported by: adrya.stembridge@… Owned by: Jun Omae
Priority: high Milestone: 1.0.13
Component: notification Version: 1.0.10
Severity: normal Keywords: fips, md5, sendmail, error

Added [notification] message_id_hash option to specify hash algorithm instead of md5 in FIPS mode.

Description

I recently upgraded our server from EL6 to EL7, however the major change is that this system is now running in FIPS mode.

Trac works OK, except that when I submit a new ticket or reply to an existing ticket, the following error appears at the top of the Trac view:

Warning: The ticket has been created, but an error occurred while sending notifications: error:060800A3:digital envelope routines:EVP_DigestInit_ex:disabled for fips

I have loglevel set to DEBUG in trac.ini, however nothing is being written there that has the same timestamp of the ticket addition/reply.

I am able to send mail from command line using mail user@example.com with the standard options.

Here is the notifications section of trac.ini

[notification]
admit_domains =
always_notify_owner = true
always_notify_reporter = true
always_notify_updater = true
default_email_format = text/html
email_sender = SendmailEmailSender
ignore_domains =
mime_encoding = none
sendmail_path = /usr/sbin/sendmail
smtp_always_bcc = 
smtp_always_cc =
smtp_default_domain =
smtp_enabled = true
smtp_from = trac@localhost
smtp_from_name =
smtp_password =
smtp_port = 25
smtp_replyto = trac@localhost
smtp_server = localhost

The sendmail path is valid, so what else would cause TRAC to generate the "error:060800A3:digital envelope routines:EVP_DigestInit_ex:disabled for fips" error message?

Keywords: fips md5 sendmail error added

comment:2 by Ryan J Ollos, 8 years ago

According to what I've read, md5 isn't allowed on a FIPS compliant system. There are two instances of md5 used in notification module: tags/trac-1.0.10/trac/ticket/notification.py@:467,614#L462. Maybe we should use sha1 or another algorithm.

Could you try t12562.diff?

comment:4 by anonymous, 8 years ago

t12562.diff worked. Got my first email notification just now.

comment:5 by Ryan J Ollos, 8 years ago

Milestone: 1.0.13

Thanks for testing. I'll wait to hear if any other devs have an opinion about the patch.

comment:6 by Jun Omae, 8 years ago

That patch would change Message-ID and break email threading. I think we should keep it if possible.

comment:7 by Ryan J Ollos, 8 years ago

The email threading issue didn't worry me too much. Other solutions are welcome.

I've noticed Message-ID in ticket notification is changed from 1.0-stable to 1.2-stable but didn't investigate it.

1.0-stable: MD5 with env.project_url, '%08d' % ticket.id, 0 and recipient address are used at tags/trac-1.0.12/trac/ticket/notification.py#L462:

http://localhost/project.url.00000001.0."Joe User" <joe.user@example.org>

1.2-stable: MD5 with env.project_url, ticket id, 0 and event's realm are used in new notification system at branches/1.2-stable/trac/notification/mail.py@14877:379-381#L364:

http://localhost/project.url.1.0.ticket

I don't want the changes of Message-ID between 1.0-stable and 1.2-stable but it's hard to make same.

comment:9 by Jun Omae, 8 years ago

What about adding [notification] message_id_hash option to specify hash algorithm? jomae.git@t12562_1.0

In addition, jomae.git@t12562_1.2 includes fix to keep Message-ID between 1.2-stable and 1.0-stable.

comment:10 by Ryan J Ollos, 8 years ago

The changes look like the best option for resolving the issue.

trac was updated to 1.0.13 yesterday (by yum), and I started getting a similar error again.

I added

message_id_hash = sha1

To the trac.ini → [notification] section, restarted apache, and am getting email notifications again.

Thanks again for the patch and update.
