Hi Sending the below mentioned patch as an attachment. Please review.
Thanks, Sakar -----Original Message----- From: Sakar Arora [mailto:sakar.ar...@nxp.com] Sent: Saturday, October 15, 2016 1:26 AM To: grub-devel@gnu.org Cc: Bhupesh Sharma <bhupesh.sha...@nxp.com>; Sakar Arora <sakar.ar...@nxp.com> Subject: [PATCH] net/ip: Fix limit_time calculation in freeing old fragments From: Sakar Arora <sakar.ar...@nxp.com> limit_time underflows when current time is less than 90000ms. This causes packet fragments received during this time, i.e., till 90000ms pass since timer init, to be rejected. Hence, set it to 0 if its less than 90000.
