2022-04-15lib: simplify u16_strdup()Heinrich Schuchardt

2022-04-15lib: convert u16_strlen() into a macroHeinrich Schuchardt

Provide functions to convert an UTF-8 stream to code page 437 or UTF-32. Add unit tests. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
2021-03-07lib/charset: utf8_get() should return errorHeinrich Schuchardt
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 <xypron.glpk@gmx.de>
2021-03-07efi_loader: carve out utf_to_cp()Heinrich Schuchardt
Carve out a function to translate a Unicode code point to an 8bit codepage. Provide a unit test for the new function. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>

Move the Unicode to codepage 437 table to charset.c Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
2020-11-29charset: make u16_strnlen accessible at runtimeIlias Apalodimas
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.

2020-10-22common: rename getc() to getchar()Heinrich Schuchardt
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().

2020-05-09charset: Add support for calculating bytes occupied by a u16 stringSughosh Ganu
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 <sughosh.ganu@linaro.org> Reviewed-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
2019-09-20lib: charset: add u16_str<n>cmp()AKASHI Takahiro
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 <takahiro.akashi@linaro.org> Reviewed-by: Heinrich Schuchardt <xypron.glpk@gmx.de>

2019-02-13lib: add u16_strcpy/strdup functionsAkashi, Takahiro
Add u16_strcpy() and u16_strdup(). The latter function will be used later in implementing efi HII database protocol. Signed-off-by: Akashi Takahiro <takahiro.akashi@linaro.org> Reviewed-by: Heinrich Schuchardt <xypron.glpk@gmx.de> Signed-off-by: Alexander Graf <agraf@suse.de>
2018-10-16efi_loader: error handling in read_console()Heinrich Schuchardt
getc() might return an error code. Avoid an incorrect converison to Unicode. This addresses CoverityScan CID 184087. Reported-by: Tom Rini <trini@konsulko.com> Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de> Signed-off-by: Alexander Graf <agraf@suse.de>
2018-09-23efi_loader: support Unicode text inputHeinrich Schuchardt
Up to now the EFI_TEXT_INPUT_PROTOCOL only supported ASCII characters. With the patch it can consume UTF-8 from the console. Currently only the serial console and the console can deliver UTF-8. Local consoles are restricted to ASCII. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de> Signed-off-by: Alexander Graf <agraf@suse.de>

2018-09-23efi_loader: rename utf16_strlen, utf16_strnlenHeinrich Schuchardt
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. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de> Signed-off-by: Alexander Graf <agraf@suse.de>
2018-05-10SPDX: Convert a few files that were missed beforeTom Rini
As part of the main conversion a few files were missed. These files had additional whitespace after the '*' and before the SPDX tag and my previous regex was too strict. This time I did a grep for all SPDX tags and then filtered out anything that matched the correct styles.
