efi_loader: initialize device path on alloc

2018-04-04T09:22:35+00:00

Since the backing memory for a new device path can contain stale
data we have to make sure that we zero the buffer.  Otherwise some
code paths that don't set all fields in a structure backed by this
device path might contain unwanted stale data.

efi_loader: Fix network DP with DM_ETH

2018-04-04T09:09:18+00:00

When CONFIG_DM_ETH is set, we assemble the device path properly with a
full device hierarchy. Our helper function dp_fill() even put the MAC
node itself in it for us.

However, for non-DM compatibility we also have code in that added the
MAC node manually. That code now runs on top of the existing MAC node:

  Handle 0x3db2f6b0
    /HardwareVendor(e61d73b9-a384-4acc-aeab-82e828f3628b)[0: ]
    /USBClass(0,0,9,0,0)/USBClass(424,9514,9,0,2)/MacAddr(b8:27:eb:e1:81:47,1)
    /MacAddr(b8:27:eb:e1:81:47,57)/EndEntire

We obviously don't need the additional node and in fact, grub chokes on
it and fails to match the DP against the ethernet device node. So this
patch moves the additional MAC node into the non-DM code path:

  Handle 0x3db3fde0
    /HardwareVendor(e61d73b9-a384-4acc-aeab-82e828f3628b)[0: ]
    /USBClass(0,0,9,0,0)/USBClass(424,9514,9,0,2)/MacAddr(b8:27:eb:e1:81:47,1)
    /EndEntire

While at it, we also mark the non-DM MAC node as ethernet.

efi_loader: provide function to get last node of a device path

2018-01-22T22:09:14+00:00

On a block device and its partitions the same protocols can be
installed. To tell the apart we can use the type of the last
node of the device path which is not the end node.

The patch provides a utility function to find this last node.

efi_loader: return NULL from device path functions

2018-01-22T22:09:13+00:00

For the construction of device paths we need to call the
AllocatePool service. We should not ignore if it fails due to an
out of memory situation.

This patch changes the device path functions to return NULL if
the memory allocation fails.

Additional patches will be needed to fix the callers.
