Subject: [PATCH v5 0/3] net: tulip: add checks to avoid OOB access
Date: Thu, 19 Mar 2020 23:10:47 +0530	[thread overview]
Message-ID: <20200319174050.759794-1-ppandit@redhat.com> (raw)

From: Prasad J Pandit <pjp@fedoraproject.org>

Hello,

* This series adds checks to avoid potential OOB access and infinite loop
  issues while processing rx/tx data.

* Tulip tx descriptors are capped at 128 to avoid infinite loop in
  tulip_xmit_list_update(), wrt Tulip kernel driver
  -> https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/net/ethernet/dec/tulip/tulip.h#n319

* Update v3: add .can_receive routine
  -> https://lists.gnu.org/archive/html/qemu-devel/2020-02/msg06275.html

* Update v4: flush queued packets once they are received
  -> https://lists.gnu.org/archive/html/qemu-devel/2020-03/msg05868.html

* Update v5: fixed a typo in patch commit message
  -> https://lists.gnu.org/archive/html/qemu-devel/2020-03/msg06209.html

Thank you.
