++visibility Hello, any feedback here? -----Original Message----- From: devel@edk2.groups.io <devel@edk2.groups.io> On Behalf Of Li, Yi Sent: Monday, June 5, 2023 2:30 PM To: devel@edk2.groups.io Cc: Li, Yi1 <yi1...@intel.com>; Maciej Rabeda <maciej.rab...@linux.intel.com>; Siyuan Fu <siyuan...@intel.com> Subject: [edk2-devel] [PATCH] NetworkPkg: Correct the length of EAP Identity when in ASCII format
FIX: https://bugzilla.tianocore.org/show_bug.cgi?id=4477 Tls connection fail over WiFi in AMT OCR flow due to invalid identity. This was due to missing conversion between unicode and ascii string which resulted in invalid strlen.
