[LU-8227] kernel update [RHEL6.8 2.6.32-642.1.1.el6]

• Status: Resolved
• Project: Lustre
• Fix Version/s: Lustre 2.9.0
• Type: Bug
• Priority: Minor
• Reporter: Bob Glossman (Inactive)
• Assignee: Bob Glossman (Inactive)
• Resolution: Fixed
• Severity: 3

Description

• When a transparent proxy application was running and the number of established
  connections on the computer exceeded one million, unrelated processes, such as
  curl or ssh, were unable to bind to a local IP on the box to initiate a
  connection. The provided patch fixes the cooperation of the
  REUSEADDR/NOREUSEADDR socket option, and thus prevents the local port from being
  exhausted. As a result, the aforementioned bug no longer occurs in the described
  scenario. (BZ#1333571)

• Previously, packets including the Common IP Security Option (CIPSO) label tag
  type 5 with certain category ranges were not read correctly. As a consequence,
  these packets were interpreted with the fallback security label. The provided
  patch fixes the netlbl_secattr_catmap_setrng() function, and thus fixes this
  bug. (BZ#1333579)

• When hot removing or adding devices from a RAID1 array, the raid1d
  daemon could deadlock and become unresponsive in the freeze_array() function.
  The provided patch includes bio_end_io_list writes in the nr_queued variable to
  prevent the aforementioned hang from occurring. (BZ#1333576)

Can some back port this to b2_5_fe

[Jian Yu]

Hi James,

Bob is back-porting the patch.

[James A Simmons]

Just want to send out a warning. At ORNL we moved to this kernel and found a nasty kernel bug in the SRP code. So if you are running srp_login you might see your kernel crash on the bring up of your servers.

James,
Thanks for the heads up. I don't think we've heard of this before. Is there an upstream bugzilla or other bug report we can follow on the issue?

James,
Thanks, but can't see either of those bug reports. I just get:

You are not authorized to access bug #xxxxxxx.

Most likely the bug has been restricted for internal development processes and we cannot grant access.

[James A Simmons]

Me too I guess only are admins have access to those bugs. I will keep you posted on the progress of this bug
