lib/charset: utf8_get() should return error

2021-03-07T16:37:13+00:00

utf8_get() should return an error if hitting an illegal UTF-8 sequence and not silently convert the input to a question mark. Correct utf_8() and the its unit test. console_read_unicode() now will ignore illegal UTF-8 sequences. Signed-off-by: Heinrich Schuchardt

charset: make u16_strnlen accessible at runtime

2020-11-29T04:18:37+00:00

commit 1fabfeef506c ("efi_loader: parameter check in GetNextVariableName()") introduces a check using u16_strnlen(). This code is used on EFI runtime variables as well, so unless we mark it as runtime, the kernel will crash trying to access it.

common: rename getc() to getchar()

2020-10-22T13:54:53+00:00

The sandbox is built with the SDL2 library with invokes the X11 library which in turn calls getc(). But getc() in glibc is defined as int getc(FILE *) This does not match our definition. int getc(void) The sandbox crashes when called with parameter -l. Rename our library symbol getc() to getchar().

charset: Add support for calculating bytes occupied by a u16 string

2020-05-09T07:30:28+00:00

The current code uses 'u16_strlen(x) + 1) * sizeof(u16)' in various places to calculate the number of bytes occupied by a u16 string. Let's introduce a wrapper around this. This wrapper is used on following patches Signed-off-by: Sughosh Ganu Reviewed-by: Heinrich Schuchardt

lib: charset: add u16_strcmp()

2019-09-20T18:09:19+00:00

u16 version of strcmp(): u16_strncmp() works like u16_strcmp() but only at most n characters (in u16) are compared. This function will be used in my UEFI secure boot patch. Signed-off-by: AKASHI Takahiro Reviewed-by: Heinrich Schuchardt

efi_loader: support unaligned u16 strings

2019-07-16T22:17:22+00:00

Allow unaligned u16 strings as arguments to u16_strdup() and u16_strlen(). Signed-off-by: Heinrich Schuchardt

lib: add u16_strcpy/strdup functions

2019-02-13T08:40:05+00:00

Add u16_strcpy() and u16_strdup(). The latter function will be used later in implementing efi HII database protocol. Signed-off-by: Akashi Takahiro Reviewed-by: Heinrich Schuchardt Signed-off-by: Alexander Graf
