efi: Select also CMD_DHCP from EFI_HTTP_BOOT

2025-08-30T18:45:33+00:00

This is needed because distro_efi_read_bootflow_net will then need
dhcp_run which is not already enabled by CMD_NET.

efi_loader: Make EFI_VARIABLES_PRESEED depend on !COMPILE_TEST

2025-08-30T18:45:33+00:00

When doing compile testing build we cannot rely on having a valid file
for EFI_VAR_SEED_FILE to exist, so disable this option when doing
compile tests.

lwip: tftp: resend initial request

2025-08-18T13:47:58+00:00

The TFTP implementation does not resend the initial request if there is
no response from the server. Since TFTP is based on UDP, there should be
a mechanism to deal with unreliable transmissions at this point, similar
to what we have for data packets. Therefore, introduce request
retransmission.

net: lwip: add Kconfig option to show ICMP unreachable errors

2025-08-18T12:08:57+00:00

Add Kconfig symbol LWIP_ICMP_SHOW_UNREACH which, when enabled, prints a
message to the console upon reception of ICMP unreachable messages. For
example:

 $ make qemu_arm64_lwip_defconfig
 $ qemu-system-aarch64 -M virt -cpu max -nographic -bios u-boot.bin

efi_loader: add missing check in FMP.GetImageInfo()

2025-07-26T05:37:03+00:00

The UEFI 2.11 specification, chapter 23.1.3 requires
EFI_FIRMWARE_MANAGEMENT_PROTOCOL.GetImageInfo() to return
EFI_INVALID_PARAMETER if *ImageInfoSize is not too small
and ImageInfo is NULL.

efi_selftest: fix ESRT creation tests

2025-07-26T05:37:03+00:00

The code foresees that parameters descriptor_size and descriptor_count
might be NULL and then dereferences them without further check.

The size check must take into account the descriptor count.

ImageInfo might be NULL. In this case we must not dereference it.

efi_loader: correct EFI_DEBUG_TABLE_ENTRY_SIZE

2025-07-26T05:37:03+00:00

With the current code we allocate to little memory when adding entries to
the EFI_DEBUG_INFO_TABLE and we fail to correctly move entries when an
entry is removed.

EFI_DEBUG_TABLE_ENTRY_SIZE must be the size of an entry in the
EFI_DEBUG_INFO_TABLE, not the size of a pointer.
