Hi Jiaxin, 1. I've verified, IPv6 support condition check for HTTP/ISCSI, It works fine and the ASSERT issue also resolved. 2. Regards Display Initiator IP, It resolves the issues the issues which I've mentioned previously. 3. I found some other issue in ISCSI, Below are the details A. Add Attempt1 with Target Info via Static and provide Target Name & Target IP, Save changes. B. If we are trying to add another attempt , It is taking Target IP as default IP which is same Target IP given in Attempt1. Could you please check at your end provide your comments on 3rd one.
Thank You, Karunakar -----Original Message----- From: Wu, Jiaxin [mailto:jiaxin...@intel.com] Sent: Wednesday, October 18, 2017 2:30 PM To: Karunakar P; edk2-devel@lists.01.org Cc: Ye, Ting; Fu, Siyuan Subject: RE: [edk2] [Patch 0/2] Add IPv6 support condition check for HTTP/ISCSI. Hi Karunakar, Actually, in my part, I didn't meet the ASSERT no matter the "Ipv6Available" returned from HttpBootCheckIpv6Support is true or false. According your ASSERT case that happened in Ip4DxeDriverBindingStart, which is caused by the FreePool of Private in Ip6DxeDriverBindingStart, so I guess the Ip6DxeDriverBindingStart may be involved ahead of Ip4DxeDriverBindingStart, then something wrong happened in Ip6DxeDriverBindingStart and goto the ON_ERROR (Private is freed here!). so, you can add the breakpoint within Ip6DxeDriverBindingStart/Ip4DxeDriverBindingStart to check it. Per my analysis above, it does the issue that may trigger the potential ASSERT. So, I refined the patch as version2. The principle of patch v2 is that IPv6 and IPv4 should not affect each other even any failure happen, but the original code doesn't follow that:).
