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.
