efi_loader: efi_dp_check_length()

2020-08-24T14:37:53+00:00

We need to check that device paths provided via UEFI variables are not
malformed.

Provide function efi_dp_check_length() to check if a device path has an
end node within a given number of bytes.

efi_loader: device path for SATA devices

2020-05-21T08:00:17+00:00

Provide device path nodes for SATA devices.

This avoids creation of two handles with the same device path indicating
our root node.

This is what the device paths for a SATA drive with four partitions could
like:

/VenHw(..)/Sata(0x0,0xffff,0x0)
/VenHw(..)/Sata(0x0,0xffff,0x0)/HD(1,MBR,0x81ea591f,0x800,0x63ff830)
/VenHw(..)/Sata(0x0,0xffff,0x0)/HD(2,MBR,0x81ea591f,0x6400800,0x9ff830)
/VenHw(..)/Sata(0x0,0xffff,0x0)/HD(3,MBR,0x81ea591f,0x6e00800,0x16ef2ab0)
/VenHw(..)/Sata(0x0,0xffff,0x0)/HD(4,MBR,0x81ea591f,0x1dcf3800,0x1dcedab0)

efi_loader: device path for virtio block devices

2020-05-21T08:00:17+00:00

The UEFI specification does not define a device sub-type for virtio.
Let's use a vendor hardware node here.

This avoids creation of two handles with the same device path indicating
our root node.

common: Drop log.h from common header

Move this header out of the common header.

part: Drop disk_partition_t typedef

2020-05-18T21:33:33+00:00

We should not be using typedefs and these make it harder to use
forward declarations (to reduce header file inclusions). Drop the typedef.

common: Drop net.h from common header

2020-05-18T21:33:31+00:00

Move this header out of the common header. Network support is used in
quite a few places but it still does not warrant blanket inclusion.

Note that this net.h header itself has quite a lot in it. It could be
split into the driver-mode support, functions, structures, checksumming,
etc.

efi_loader: remove unused function efi_dp_from_dev()

efi_loader: fix efi_dp_from_name()

2019-11-12T22:13:54+00:00

Correctly check the return value of efi_dp_from_file().
If we can determine device path for the file, should not depend on the
device path for the device being requested.
Provide a function description for efi_dp_from_name().

efi_loader: device_path: check against file path length

2019-10-17T17:19:55+00:00

device_path strcuture has 2 bytes of "length" field, and so
file path length should not exceed this limit, 65535.
