Hi Andrew,

Thanks for the reply.   By existing system, I mean that I’m trying to 
add network 
support to my Asus Q87E motherboard.   I don’t have the BIOS source for my 
board 
so I can’t build a fresh BIOS with networking stack built in.

Instead, I’m trying to load the networking DXEs from the MdePkg (EDK2) 
in the

Re: [edk2] MdeModulePkg maintainer: Possible bug in Network/Mtftp4Dxe/Mtftp4Impl.c

2014-04-18 Thread Li, Ruth

Hi Michael,

Thanks for catching this.

While we re-checked the spec, and realized there're some inconsistency in the 
UEFI Spec about the Override Data definition. As we know, 0.0.0.0 is  clearly 
not a valid unicast address.

In "Related Definitions" under EFI_MTFTP4_PROTOCOL.GetInfo():
ServerIp IP address of the MTFTPv4 server. If set to 0.0.0.0, it will use the 
value that was set by the EFI_MTFTP4_PROTOCOL.Configure()  function.
In "Status Codes Returned" table:
 EFI_INVALID_PARAMETER  One or more IPv4 addresses in OverrideData are 
not valid unicast IPv4 addresses if OverrideData is not  NULL.

We'd better have specification to clarify this. At the same time, how about you 
update your code to set a valid IP address so that to get the code running 
first?

Thanks,
Ruth

Network/Mtftp4Dxe/Mtftp4Impl.c

Hi,

I think I found a bug in MdeModulePkg/Universal/Network/Mtftp4Dxe/Mtftp4Impl.c
Regarding UEFI Specification 2.4 EFI_MTFTP_PROTCOL.GetInfo() (PDF page 1411) in 
the related definitions of Override Data is mentioned that if I use a ServerIp 
address of 0.0.0.0 the currently configured address is used instead.
But the code that checks the incoming Override parameter is checked with this 
function:
https://github.com/tianocore/edk2/blob/master/MdeModulePkg/Universal/Network/Mtftp4Dxe/Mtftp4Impl.c#L187

BOOLEAN
Mtftp4OverrideValid (
  IN MTFTP4_PROTOCOL  *Instance,
  IN EFI_MTFTP4_OVERRIDE_DATA *Override
  )
{
  EFI_MTFTP4_CONFIG_DATA*Config;
  IP4_ADDR  Ip;
  IP4_ADDR  Netmask;
  IP4_ADDR  Gateway;

  CopyMem (&Ip, &Override->ServerIp, sizeof (IP4_ADDR));
  if (!NetIp4IsUnicast (NTOHL (Ip), 0)) {
return FALSE;
  }
...

And if I pass there a 0.0.0.0 ip address the whole function returns FALSE and 
the calling function returns EFI_INVALID_PARAMETER:
https://github.com/tianocore/edk2/blob/master/MdeModulePkg/Universal/Network/Mtftp4Dxe/Mtftp4Impl.c#L411

Did I get something wrong or is there a bug in the code?
Compared to the gateway the gateway address is only checked with the 
NetIp4IsUnicast-function if it is not null:
https://github.com/tianocore/edk2/blob/master/MdeModulePkg/Universal/Network/Mtftp4Dxe/Mtftp4Impl.c#L196


  if (!Config->UseDefaultSetting && (Gateway != 0)) {

Subject: [edk2] trying to segregate issue if it is with network card uefi 
driver or uefi network stack or dhcp server

Hi,

I am facing problem in configuring ip through uefi shell. (main purpose is to 
do uefi pxe boot on rhel6.5 pxe server)
First I tried to configure ip (dhcp) from uefi shell, which is giving attached 
logs on dhcp sever, IP is not configured.

Using command:

Shell>Ifconfig -s eth5 dhcp
After this, it doesn't get ip.
[cid:image001.png@01CF530F.C7B47120]

And
I configured IP on the same server which is running rhel (rhel6.5 OS netwotk 
stack), this means there is no issue in dhcp server setup.
How can I find out if issue is with uefi network stack or network card uefi 
driver? as network card legacy driver works fine.

Regards,
Ritul

Re: [edk2] MdeModulePkg/Universal/Network/SnpDxp/Station_address.c

2014-03-11 Thread Li, Ruth

Hi Ari,

I tend to agree with your assessment.

At the same time, I checked UEFI/code again. It turns out the 
PXE_OPFLAGS_STATION_ADDRESS_READ and PXE_OPFLAG_STATION_ADDRESS_WRITE are both 
defined as zero.
[cid:image001.png@01CF3D40.5A455C10]
So, using current BIOS FW, I thought there'll be no actual functionality impact 
if you pass PXE_OPFLAGS_STATION_ADDRESS_WRITE.

Hi Ruth,

Yes, I'm developing a UNDI driver for our device.
The bellow code, if integrated into a BIOS FW, do cause me an issue as it 
implies that there is no need to pass PXE_OPFLAGS_STATION_ADDRESS_WRITE whereas 
my driver expects this kind of flag in order to perform SetAddress(). With the 
current implementation, calling to SetStationAddress on the SNP driver will not 
be processed by our UNDI driver.
I tend to think that this code is not aligned to UNDI spec.

Hi,

I found this weird comment (and consequent behavior) in the SnpDxe 
PxeSetStnAddr() implementation:
EFI_STATUS
PxeSetStnAddr (
  SNP_DRIVER  *Snp,
  EFI_MAC_ADDRESS *NewMacAddr
  )
{
...
...
Snp->Cdb.OpFlags = PXE_OPFLAGS_STATION_ADDRESS_READ;
//
// even though the OPFLAGS are set to READ, supplying a new address
// in the CPB will make undi change the mac address to the new one.
//
CopyMem (&Cpb->StationAddr, NewMacAddr, Snp->Mode.HwAddressSize);

Snp->Cdb.CPBsize  = (UINT16) sizeof (PXE_CPB_STATION_ADDRESS);
Snp->Cdb.CPBaddr  = (UINT64)(UINTN) Cpb;
  }
...
...
}

I looked through the UNDI section in the UEFI 2.4A spec for a statement 
declaring that once a CPB is present UNDI corresponding StationAddress() shall 
set the current mac address to the address specified in the CPB struct, but my 
efforts were in vain.

Can anyone refute (or substantiate) this claim?

Subject: [edk2] UEFI SCT few queries

Hi List,

I am new to UEFI and exploring about SCT.  I have very basic question regarding 
SCT.

1)  In order to use SCT in an organization, do we require any special license?
2)  Looks like SCT compliance testing is only internal to an organization. We 
don't require to publish its details outside of the organization?
3)  If anyone want to contribute to SCT test cases. Which forum/list he/she can 
be used?

Please guide me.

Regards,
Prabhakar

Ting,
here is a new patch that fixes the issue I have. Here is the details of this 
new fix:

MdeModulePkg/ArpDxe: Retrieve a copy of SnpMode after SNP has been 
configured

Before ARP configures its MNP child it gets a copy of SnpMode.
If it is the first configured MNP child then SNP is also initialized.
It may only be at this time the MAC address of the network card be valid 
(ie:
the initial copy of SnpMode would contain an invalid/null MAC address).

Olivier,

Thanks for your patch. Though I don't quite agree with you that SnpMode cannot 
be accessed prior to SNP is configured.

As I known some parameters in SnpMode will be initialized in 
SimpleNetworkDriverStart() by calling undi.GetInitInfo. These parameters will 
not be updated by other APIs in SNP protocol including SNP->initialize. One of 
these parameters is 'IfType' used in ARP driver from your patch. Thus I think 
it makes sense that upper layer driver uses this kind of info prior to 
configure SNP to save performance lost in some conditions.

Ting

Dear MdeModulePkg maintainer,
Please find the attached patch that retrieved SnpMode only after configuring 
Snp.

When Arp driver starts (with ArpDriverBindingStart()), its service will be 
created
and the Mnp child configured (ArpService->Mnp->Configure() called in 
ArpCreateService()).

It is only at this time the Snp protocol will be initialized (at the end of 
MnpStart()).
So, a valid SnpMode could not be expected prior to ArpService->Mnp->Configure().

Subject: [edk2] MNP PaddingSize Question

I've been tracking down a performance issue and have isolated it to this piece 
of MNP initialization code:

  //
  // Make sure the protocol headers immediately following the media header
  // 4-byte aligned, and also preserve additional space for VLAN tag
  //
  MnpDeviceData->PaddingSize = ((4 - SnpMode->MediaHeaderSize) & 0x3) + 
NET_VLAN_TAG_LEN;

On my system this is coming up with '6' (MediaHeaderSize = 0xE) which is 
causing performance issues since some of the memory copies to the resulting 
non-dword aligned addresses are slower.  As an experiment I tried bumping this 
number to '8' and things worked well.

This value is used later when NET_BUFs are being allocated:

if (MnpDeviceData->PaddingSize > 0) {
  //
  // Pad padding bytes before the media header
  //
  NetbufAllocSpace (Nbuf, MnpDeviceData->PaddingSize, NET_BUF_TAIL);
  NetbufTrim (Nbuf, MnpDeviceData->PaddingSize, NET_BUF_HEAD);
}

Can someone explain the purpose of PaddingSize and how that affects the later 
processing of packets?  Is this number a minimum value and is ok to be larger?

Thanks,

Eugene

Hi Ruth, thanks for the prompt reply.

First, I must say that I'm a little surprised by your claim that EDK2 does not 
support S/W UNDI as there is that E100b UNDI driver which happens to work just 
fine under EDK2 implementation and it doesn't seem to be an H/W one.  
(Particularly, it explicitly exposes PXE_SW_UNDI as its !PXE struct. See 
edk2/OptionRomPkg/UndiRuntimeDxe/Init.c:20 and the corresponding implementation 
in SnpDxe/Snp.c:422). Moreover, our device also managed to function under EDK2 
as a S/W UNDI.
Second, assuming that EDK2 will eventually work with S/W UNDI - which module in 
the network stack is responsible for the fragmentation?

Thanks,

Ari

Hi,

As no driver in the EDK2 network stack uses Fragmented Transmit 
(PXE_OPFLAGS_TRANSMIT_FRAGMENTED), not even the SnpDxe one, and nevertheless, 
fragmented Ip packets manage to go on the wire (I checked it), what is the 
purpose of this opflag? Who might  partition the packets into fragments? Does 
it need special care?

Another issue is the PXE_OPFLAGS_TRANSMIT_BLOCK/DON'T_BLOCK:
The SnpDxe driver ignores these flags and do not pass them to the UNDI driver. 
The edk2 platform performs UNDI GetStatus periodically to handle the completed 
TX buffers, so I presume the system works in a non-blocking mode, doesn't it? 
Or it might be a bug in the SnpDxe implementation...

Thnaks,

Re: [edk2] DHCP Fast Mode Patch

2012-09-17 Thread Li, Ruth

Eugene,

For this problem, I would prefer using UEFI defined dhcp callback method to 
achieve the platform policy of 'select first offer' or any other policy. And 
using dhcp callback mechanism, you have opportunity to do more dhcp-packet 
validation to guarantee the first received option is actually correct one.

Currently, both IPv4 and IPv6 already support this mechanism.

For DHCPv4,
In MdeModulePkg\Universal\Network\Dhcp4Dxe\Dhcp4Io.c,
DhcpHandleSelect() will invoke callback function (Dhcp4Event = Dhcp4RcvdOffer) 
when a DHCP offer is received.
DhcpChooseOffer() will invoke callback function (Dhcp4Event = Dhcp4SelectOffer) 
to see if user wants to select a special offer.

For DHCPv6,
In NetworkPkg\Dhcp6Dxe\Dhcp6Io.c
Dhcp6HandleAdvertiseMsg() and Dhcp6SelectAdvertiseMsg() do the same thing as v4.

Ruth

callbacks but this approach provides a more compact solution (3 lines of code).
