2022-10-06cmd: simplify do_env_set_efi()Heinrich Schuchardt
Use efi_convert_string() to convert a UTF-8 to a UTF-16 string. Signed-off-by: Heinrich Schuchardt <heinrich.schuchardt@canonical.com>
2022-06-19cmd: correct return value for printenv -eHeinrich Schuchardt
If printenv -e is executed and the specified variable is not found, the return value $? of the command should be 1 (false). Signed-off-by: Heinrich Schuchardt <heinrich.schuchardt@canonical.com>
2022-01-19cmd: printenv: simplify printing GUIDsHeinrich Schuchardt
Use "%pS" to print text representations of GUIDs. Signed-off-by: Heinrich Schuchardt <heinrich.schuchardt@canonical.com>
2021-09-11efi_loader: eliminate EFI_CALL() in nvedit_efi.cHeinrich Schuchardt
Reduce the code size by avoiding using the external UEFI API and using our internal functions instead. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
2021-08-02global: Convert simple_strtoul() with hex to hextoul()Simon Glass
It is a pain to have to specify the value 16 in each call. Add a new hextoul() function and update the code to use it. Add a proper comment to simple_strtoul() while we are here. Signed-off-by: Simon Glass <sjg@chromium.org>
2021-07-05env: efi: fix a wrong address dereferenceAKASHI Takahiro
Probably, a pointer to a variable in an inner block should not be exposed to an outer block. Fixes: c70f44817d46 ("efi_loader: simplify 'printenv -e'") Signed-off-by: AKASHI Takahiro <takahiro.akashi@linaro.org> [trini: Don't make guid const now] Signed-off-by: Tom Rini <trini@konsulko.com>
2020-08-24efi_loader: use ':' as separator for setenv -iHeinrich Schuchardt
setenv -e -i <address>,<filesize> can be used to set a UEFI variable from memory. For separating an address and a size we use ':' in most commands. Let's do the same for setenv -e -i. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
2020-07-16efi_loader: simplify 'printenv -e'Heinrich Schuchardt
Currently default output of 'printenv -e' is restricted to variables with GUID EFI_GLOBAL_VARIABLE. This excludes db and dbx. As the number of variables is small there is no need for this restriction. If no GUID is provided, print all matching variables irrespective of GUID. Always show the numeric value of the GUID. If the GUID provided to 'setenv -e' is invalid, return CMD_RET_USAGE. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
2020-07-11efi_loader: display RO attribute in printenv -eHeinrich Schuchardt
Let the 'printenv -e' command display the read only flag. If the variable is time authenticated write the time stamp. Avoid EFI_CALL() when calling SetVariable() and GetVariable(). Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
2020-05-18command: Remove the cmd_tbl_t typedefSimon Glass
We should not use typedefs in U-Boot. They cannot be used as forward declarations which means that header files must include the full header to access them. Drop the typedef and rename the struct to remove the _s suffix which is now not useful. This requires quite a few header-file additions. Signed-off-by: Simon Glass <sjg@chromium.org>
2020-05-18common: Drop uuid.h from common headerSimon Glass
Move this uncommon header out of the common header. Signed-off-by: Simon Glass <sjg@chromium.org>
2020-05-07efi_loader: use logical and in do_env_print_efi()Heinrich Schuchardt
If we want to check if two booleans are true, we should use a logical conjunction (&&) and not a bitwise and-operator (&). Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
2020-04-16cmd: env: add "-at" option to "env set -e" commandAKASHI Takahiro
With "-at" option, EFI_VARIABLE_TIME_BASED_AUTHENTICATED_WRITE_ACCESS will be passed to SetVariable() to authenticate the variable. Signed-off-by: AKASHI Takahiro <takahiro.akashi@linaro.org>
2020-04-16cmd: env: use appropriate guid for authenticated UEFI variableAKASHI Takahiro
A signature database variable is associated with a specific guid. For convenience, if user doesn't supply any guid info, "env set|print -e" should complement it. Signed-off-by: AKASHI Takahiro <takahiro.akashi@linaro.org>
2019-10-30cmd: env: extend "env [set|print] -e" to manage UEFI variablesAKASHI Takahiro
With this patch, when setting UEFI variable with "env set -e" command, we will be able to - specify vendor guid with "-guid guid", - specify variable attributes, BOOTSERVICE_ACCESS, RUNTIME_ACCESS, respectively with "-bs" and "-rt", - append a value instead of overwriting with "-a", - use memory as variable's value instead of explicit values given at the command line with "-i address,size" If guid is not explicitly given, default value will be used. Meanwhile, "env print -e," will be modified so that it will NOT dump a variable's value if '-n' is specified.

2019-10-06cmd: env: fix a typo in a comment of do_env_set_efi()AKASHI Takahiro

2019-06-04cmd: env: add -nv option for UEFI non-volatile variableAKASHI Takahiro
With this option, -nv, at "setenv -e" command, a variable will be defined as non-volatile. Signed-off-by: AKASHI Takahiro <takahiro.akashi@linaro.org> Reviewed-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
2019-06-04cmd: env: print a message when setting UEFI variable failedAKASHI Takahiro

2019-05-02efi_loader: memory leak in append valueHeinrich Schuchardt
When printing an UEFI variable an error may arise while converting an illegal hexadecimal value. In this case a buffer is leaked. Close the memory leak. Provide an error message. Reported-by: Coverity (CID 185830) Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
2019-03-20efi_loader: memory leak in efi_dump_single_var()Heinrich Schuchardt

2019-02-25cmd: env: add "-e" option for handling UEFI variablesAKASHI Takahiro
"env [print|set] -e" allows for handling uefi variables without knowing details about mapping to corresponding u-boot variables. Signed-off-by: AKASHI Takahiro <takahiro.akashi@linaro.org> Reviewed-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
