NetworkPkg TcpDxe: Fixed system stuck on PXE boot flow in iPXE environment
This bug fix is based on the following commit "NetworkPkg TcpDxe: SECURITY
PATCH"
REF: 1904a64
Issue Description:
An "Invalid handle" error was detected during runtime when attempting to
destroy a child instance of the hashing protocol. The problematic code segment
was:
NetworkPkg\TcpDxe\TcpDriver.c
Status = Hash2ServiceBinding->DestroyChild(Hash2ServiceBinding,
&mHash2ServiceHandle);
Root Cause Analysis:
The root cause of the error was the passing of an incorrect parameter type, a
pointer to an EFI_HANDLE instead of an EFI_HANDLE itself, to the DestroyChild
function. This mismatch resulted in the function receiving an invalid handle.
Implemented Solution:
To resolve this issue, the function call was corrected to pass
mHash2ServiceHandle directly:
NetworkPkg\TcpDxe\TcpDriver.c
Status = Hash2ServiceBinding->DestroyChild(Hash2ServiceBinding,
mHash2ServiceHandle);
This modification ensures the correct handle type is used, effectively
rectifying the "Invalid handle" error.
Verification:
Testing has been conducted, confirming the efficacy of the fix. Additionally,
the BIOS can boot into the OS in an iPXE environment.
