Subject: [PATCH] TFTP : tftp fix for full volume case
Date: Mon, 25 Sep 2017 20:07:29 +0530 [thread overview]
Message-ID: <1506350249-28082-1-git-send-email-meenakshi.aggarwal@nxp.com> (raw)
Issue :
When storage media is full, tftp was resulting in ASSERT
MdeModulePkg/Core/Dxe/Mem/Page.c, because number of pages
was zero.
Reason:
While doing tftp, function call ShellWriteFile was modifying
FileSize variable. In case of full disk it was coming out to be
Zero.
Fix:
Storage the original filesize in local variable, and use this
variable while freeing the pages.
