This gets called each time a payload is to get executed by bootefi.
For now this only updates the PXE IP address.
Signed-off-by: Adriano Cordova <adriano.cordova@canonical.com>
The coomand bootefi calls efi_init_obj_list to do the efi set up
before launching an .efi payload, but efi_init_obj_list is called
only once. There are some initializations which depend on the
environment and should be done each time a payload gets launched and
not only once. A motivation for this changes is the following order
of events:
1. Launch an EFI application (e.g. bootefi hello)
2. Change the ip address
3. Launch another application which uses the pxe protocol
As the EFI pxe protocol was initialized when the handles
for efi net were created in 1., the ip was hardcoded there.
In this example, another possibility would be to make a callback for ip
address changes to go all the way up to efi_net.

This series adds support for file renaming to EFI_FILE_PROTOCOL.SetInfo().
One of the use cases for renaming in EFI is to facilitate boot loader
boot counting.
No existing filesystems in U-Boot currently include file renaming,
resulting in support for renaming at the filesystem level and a
concrete implementation for the FAT filesystem.

In reworking the BLK usage in Kconfig, I found there's a few issues with
EFI_LOADER=y and BLK=n. In general, we can easily say that
lib/efi_loader/efi_file.c also should only be built with CONFIG_BLK.
That however leaves the bootmgr code, eficonfig code and then parts of
efi_device_path.c, efi_boottime.c and efi_setup.c which functionally
depend on BLK. While these calls can be if'd out, I'm unsure if the
result is usable. So rather than leave that buildable and imply that it
is, I'm leaving that combination non-buildable and commenting that
EFI_LOADER depends on BLK in the Kconfig currently.

The fix provided by 997fc12ec9 is actually introducing
a buffer overrun, and the overrun is effective if the
memory after the reloc section is not zeroed.
Probably that's why this bug is not always noticeable.
The problem is that 8-bytes 'rel' pointer can be 4-bytes aligned
according to the PE Format, so the actual relocate function can
take values after the reloc section.
One example is the following dump from the reloc section:
bce26000: 3000 0000 000c 0000 0000 0000 0000 0000
bce26010: 7c00 9340 67e0 f900 1c00 0ea1 a400 0f20
This section has two relocations at offset bce26008 and bce2600a,
however the given size (rel_size) for this relocation is 16-bytes
and this is coming form the efi image Misc.VirtualSize, so in this
case the 'reloc' pointer ends at affset bce2600c and is taken as
valid and this is where the overflow is.
In our system we see this problem when we are starting the
Boot Guard efi image.
This patch is fixing the overrun while preserving the fix done
by 997fc12ec9.

Add network-stack agnostic way to send an http request and
parse http headers from efi drivers. This uses wget as a
backend and communicates with it via efi_wget_info.
The function efi_net_do_request allocates a buffer on behalf of an
efi application using efi_alloc and passes it to wget to receive
the data. If the method is GET and the buffer is too small, it
re-allocates the buffer based on the last received Content-Length
header and tries again. If the method is HEAD it just issues one
request. So issuing a HEAD request (to update Content-Length) and
then a GET request is preferred but not required.
The function efi_net_parse_headers parses a raw buffer containing
an http header into an array of EFI specific 'http_header' structs.
