Here we're assuming IfrFormNvData->DhcpEnable is TRUE. Should we check it before setting the policy and calling SetData()?

Hello Saloni,

Thanks for the feedback. After the reset, or when we disable configure from menu, GetData returns policy to static as the enum value is 0. However, setting value as static does not have any benefit as it forces to reuse the old network settings. Using DHCP really mimics the reset behavior that we see without any configuration done manually.

Thanks
Ashish

Makes sense. Should we also set IfrNvData->DhcpEnable = TRUE when updating the Policy then?

Re: [edk2-devel] [PATCH] NetworkPkg/Ip4Dxe: Fix Reset To Default
Posted by Ashish Singhal via groups.io 3 months, 3 weeks ago 
I do not recommend doing that. Setting policy via SetData does enough to wipe out any previous manual configuration and that is the goal for reset to default.

Makes sense. Should we also set IfrNvData->DhcpEnable = TRUE when updating the Policy then?

Hello Saloni,



Thanks for the feedback. After the reset, or when we disable configure from menu, GetData returns policy to static as the enum value is 0. However, setting value as static does not have any benefit as it forces to reuse the old network settings. Using DHCP really mimics the reset behavior that we see without any configuration done manually.



Thanks

Ashish

Hi Ashish,



+    Ip4NvData->Policy = Ip4Config2PolicyDhcp;

+    Status            = Ip4Cfg2->SetData (

+                                   Ip4Cfg2,

+                                   Ip4Config2DataTypePolicy,

+                                   sizeof (EFI_IP4_CONFIG2_POLICY),

+                                   &Ip4NvData->Policy

+                                   );



Here we’re assuming IfrFormNvData->DhcpEnable is TRUE. Should we check it before setting the policy and calling SetData()?



Thanks,

Saloni

Yes, SetData does reset the previous configuration.

I do not recommend doing that. Setting policy via SetData does enough to wipe out any previous manual configuration and that is the goal for reset to default.

Makes sense. Should we also set IfrNvData->DhcpEnable = TRUE when updating the Policy then?

Hello Saloni,



Thanks for the feedback. After the reset, or when we disable configure from menu, GetData returns policy to static as the enum value is 0. However, setting value as static does not have any benefit as it forces to reuse the old network settings. Using DHCP really mimics the reset behavior that we see without any configuration done manually.



Thanks

Ashish

Hi Ashish,



+    Ip4NvData->Policy = Ip4Config2PolicyDhcp;

+    Status            = Ip4Cfg2->SetData (

+                                   Ip4Cfg2,

+                                   Ip4Config2DataTypePolicy,

+                                   sizeof (EFI_IP4_CONFIG2_POLICY),

+                                   &Ip4NvData->Policy

+                                   );



Here we’re assuming IfrFormNvData->DhcpEnable is TRUE. Should we check it before setting the policy and calling SetData()?



Thanks,

Saloni

Hi Ashish,
 
+    Ip4NvData->Policy = Ip4Config2PolicyDhcp;
+    Status            = Ip4Cfg2->SetData (
+                                   Ip4Cfg2,
+                                   Ip4Config2DataTypePolicy,
+                                   sizeof (EFI_IP4_CONFIG2_POLICY),
+                                   &Ip4NvData->Policy
+                                   );
 
Here we're assuming IfrFormNvData->DhcpEnable is TRUE. Should we check it before setting the policy and calling SetData()?
 
Thanks,
Saloni

Hi Michael,

If you are going to create a new PR yourself instead of using the one I already created (https://github.com/tianocore/edk2/pull/5150), should I close this one?

Thanks

I do not recommend doing that. Setting policy via SetData does enough to wipe out any previous manual configuration and that is the goal for reset to default.

Makes sense. Should we also set IfrNvData->DhcpEnable = TRUE when updating the Policy then?

Hello Saloni,

Thanks for the feedback. After the reset, or when we disable configure from menu, GetData returns policy to static as the enum value is 0. However, setting value as static does not have any benefit as it forces to reuse the old network settings. Using DHCP really mimics the reset behavior that we see without any configuration done manually.

Thanks
Ashish

Hi Michael,

If you are going to create a new PR yourself instead of using the one I already created (https://github.com/tianocore/edk2/pull/5150), should I close this one?

Thanks
Ashish

Yes, SetData does reset the previous configuration.

Subject: Re: [PATCH] NetworkPkg/Ip4Dxe: Fix Reset To Default

I do not recommend doing that. Setting policy via SetData does enough to wipe out any previous manual configuration and that is the goal for reset to default.

Makes sense. Should we also set IfrNvData->DhcpEnable = TRUE when updating the Policy then?

Subject: Re: [PATCH] NetworkPkg/Ip4Dxe: Fix Reset To Default

Hello Saloni,

Thanks for the feedback. After the reset, or when we disable configure from menu, GetData returns policy to static as the enum value is 0. However, setting value as static does not have any benefit as it forces to reuse the old network settings. Using DHCP really mimics the reset behavior that we see without any configuration done manually.

Thanks
Ashish

Hi Ashish,

+    Ip4NvData->Policy = Ip4Config2PolicyDhcp;
+    Status            = Ip4Cfg2->SetData (
+                                   Ip4Cfg2,
+                                   Ip4Config2DataTypePolicy,
+                                   sizeof (EFI_IP4_CONFIG2_POLICY),
+                                   &Ip4NvData->Policy
+                                   );

Here we're assuming IfrFormNvData->DhcpEnable is TRUE. Should we check it before setting the policy and calling SetData()?

Thanks,
Saloni

Exercising reset to default does not reset the settings.
Add handler code for the case where configuration is
disabled.
