[Bug 1314134] Re: network stack never yields control on busy networks

[Launchpad Bug Tracker]

This bug was fixed in the package grub2 - 2.02~beta2-10

---------------
grub2 (2.02~beta2-10) unstable; urgency=medium


  [ Colin Watson ]
  * Add the true module to the signed image, since 05_debian_theme uses it.
    Thanks to Dimitri John Ledkov for the report.
  * Limit test suite parallelisation to 1; the test suite seems to have some
    isolation problems at higher levels at the moment (closes: #746856).
  * Simplify override_dh_install a bit.
  * Backport patches from upstream to make the network stack more responsive
    on busy networks (LP: #1314134).

  [ Dimitri John Ledkov ]
  * Add support for nvme device in grub-mkdevicemap (closes: #746396,
    LP: #1275162).

  [ Debconf translations ]
  * Korean (Changwoo Ryu, closes: #745559).

Title:
  network stack never yields control on busy networks

Status in “grub2” package in Ubuntu:
  Fix Released
Status in “grub2” source package in Trusty:
  In Progress

Bug description:
  [Impact] GRUB's network stack tries to process all incoming packets, and thus never or rarely yields control back to other parts of GRUB when the network is busy with e.g. lots of ARP traffic.
  [Test Case] Use GRUB to netboot a system on a busy network; ensure that it is responsive.  (I've had reports of 90-minute delays in interactive response on some systems, so in those cases the difference should be dramatic and easily observable.)
  [Regression Potential] Confined to netbooting.

  These upstream patches should fix this:

    https://lists.gnu.org/archive/html/grub-devel/2014-01/msg00119.html
    https://lists.gnu.org/archive/html/grub-devel/2014-01/msg00118.html

  I plan to backport these for 14.04.1.
