With CONFIG_CMD_BOOTEFI=y, load command causes data abort
when path_to_uefi(fp->str, path) tries to write uefi path out of
bounds of u16 str[] array (check efi_device_path_file_path struct for
details). This is caused by unproper handling of void *buf pointer
in efi_dp_from_file(), particularly when the buf pointer value is changed
after dp_part_fill() invocation.

This cannot be correct. dp_part_fill() is meant to set buf to the end of
the partition device path, e.g.
/VenHw(dbca4c98-6cb0-694d-0872-819c650cb7b8)/HD(1,MBR,0xd1535d21,0x1,0x7f)
In the lines below we want to add a further device path node with the
filename followed by the end node, e.g.
/VenHw(dbca4c98-6cb0-694d-0872-819c650cb7b8)/HD(1,MBR,0xd1535d21,0x1,0x7f)/Shell.efi
With your patch we end up with a device path containing only the file
name and the end node, e.g.
/Shell.efi
If you think this is an out of bound problem we must fix the estimation
of the device path size.
For better understanding the problem could you, please, print the value
of dpsize and then call dp_alloc() with a sufficiently large argument.
Before the return statement add
printf("desc %p\n", desc);
printf("dp length %zu\n", efi_dp_size(start));
This should provide the calculated device path length and its actual size.
Please, indicate the config file that you are using.
Best regards
Heinrich

Hi Heinrich,
Thanks for looking into this,

That's why I added RFC tag, as I definitely don't understand the full
picture of what's going here(and lack of time to discover) :)

So with the changes:

Output:

And U-boot hangs on efi_dp_size(start) invocation, so I never receive
any output from the last printf() invocation.

In
http://git.denx.de/?p=u-boot-efi.git;a=shortlog;h=refs/heads/efi-2019-07
I have already added a patch the problem with efi_dp_size().
efi_loader: move efi_save_gd() call to board_r.c
http://git.denx.de/?p=u-boot-efi.git;a=commit;h=5658c83d1c3637d4aa5bc366ab987b776ea105eb
So I suggest that you start from the efi-2019-07 branch.
