lib/vsprintf: allow printing upper case GUIDs

2019-06-07T14:52:30+00:00

In the UEFI context GUIDs are expected to be rendered in upper case.

The patch uses the formerly unused bit 1 of the parameter str_format
of function uuid_bin_to_str() to indicate if we need upper or lower case
output.

Function uuid_string() in vsprint.c is adjusted to correctly set the bit
depending on the print format code.

%pUb: 01020304-0506-0708-090a-0b0c0d0e0f10
%pUB: 01020304-0506-0708-090A-0B0C0D0E0F10
%pUl: 04030201-0605-0807-090a-0b0c0d0e0f10
%pUL: 04030201-0605-0807-090A-0B0C0D0E0F10

Up to this point only a diagnostic message in mount_ubifs() using '%pUB' is
concerned by the change. Further patches are needed to adjust the UEFI
subsystem.

A unit test is provided inside the ut_print command.

vsprintf: Support phys_addr_t specifier unconditionally

2019-04-12T02:10:05+00:00

When phys_addr_t printf specifier support was first introduced in commit
1eebd14b7902 ("vsprintf: Add modifier for phys_addr_t"), it was enabled
only if CONFIG_CMD_NET was selected. Since physical addresses are not
unique to networking support it doesn't make sense to conditionally add
it in those cases only. Move support for it outside of the CMD_NET guard
so that the specifier is always supported.

efi_loader: rename utf16_strlen, utf16_strnlen

2018-09-23T19:55:29+00:00

The function names utf16_strlen() and utf16_strnlen() are misnomers.
The functions do not count utf-16 characters but non-zero words.
So let's rename them to u16_strlen and u16_strnlen().

In utf16_dup() avoid assignment in if clause.
