2023-05-31cli: avoid buffer overrunHeinrich Schuchardt1-1/+1
Invoking the sandbox with /u-boot -c ⧵0xef⧵0xbf⧵0xbd results in a segmentation fault. Function b_getch() retrieves a character from the input stream. This character may be > 0x7f. If type char is signed, static_get() will return a negative number and in parse_stream() we will use that negative number as an index for array map[] resulting in a buffer overflow.

2023-05-03common: cli_hush: Restore clear local variable supportStefan Herbrechtsmeier1-1/+7
The u-boot hush shell doesn’t support the unset command to clear a variable and therefore an empty value ("c=") should be a valid value for the set_local_var function to clear the variable. This partial reverts commit aa722529635c ("common: cli_hush: avoid dead code") and only checks for a `=` in the string. Additionally explicit call the unset_local_var function to remove the variable if the value is empty.

Make sure the 'exit' command as well as 'exit $val' command exits from environment scripts immediately and propagates return value out of those scripts fully. That means the following behavior is expected: " => setenv foo 'echo bar ; exit 1' ; run foo ; echo $? bar 1 => setenv foo 'echo bar ; exit 0' ; run foo ; echo $? bar 0 => setenv foo 'echo bar ; exit -2' ; run foo ; echo $? bar 0 " As well as the followin behavior: " => setenv foo 'echo bar ; exit 3 ; echo fail'; run foo; echo $? bar 3 => setenv foo 'echo bar ; exit 1 ; echo fail'; run foo; echo $? bar 1 => setenv foo 'echo bar ; exit 0 ; echo fail'; run foo; echo $? bar 0 => setenv foo 'echo bar ; exit -1 ; echo fail'; run foo; echo $? bar 0 => setenv foo 'echo bar ; exit -2 ; echo fail'; run foo; echo $? bar 0 => setenv foo 'echo bar ; exit ; echo fail'; run foo; echo $? bar 0 " Fixes: 8c4e3b79bd0 ("cmd: exit: Fix return value") Reviewed-by: Hector Palacios <hector.palacios@digi.com> Signed-off-by: Marek Vasut <marex@denx.de>

2021-02-02common: Drop asm/global_data.h from common headerSimon Glass1-0/+1
Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

2020-10-22cli_hush.c: remove broken sanity checkRasmus Villemoes1-8/+0
This code is intended do prevent one from setting a shell variable abc by doing abc=123 if an environment variable named abc already exists. However, the check is broken, since the env_get is done before the split on =, so we look up whether an environment variable "abc=123" exists, which is obviously never the case. One could move the code to below the split on =, but instead, just remove it, saving a little .text: The check has never worked as intended (it goes all the way back to the initial git commit), and it would anyway not guard against one first setting the shell variable, then doing 'env set abc xyz'.

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.

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini1-2/+1
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>

Hush segfaults if it sees a syntax error while attempting to parse a command: $ ./u-boot -c "'" ... syntax error Segmentation fault (core dumped) This is due to a NULL pointer dereference of in_str->p in static_peek().

2014-10-27cli: hush: Adjust 'run' command to run each line of the env varSimon Glass1-1/+2
The run command treats each argument an an environment variable. It gets the value of each variable and executes it as a command. If an environment variable contains a newline and the hush cli is used, it is supposed to execute each line one after the other. Normally a newline signals to hush to exit - this is used in normal command line entry - after a command is entered we want to return to allow the user to enter the next one. But environment variables obviously need to execute to completion. Add a special case for the execution of environment variables which continues when a newline is seen, and add a few tests to check this behaviour. Note: it's not impossible that this may cause regressions in other areas. I can't think of a case but with any change of behaviour with limited test coverage there is always a risk. From what I can tell this behaviour has been around since at least U-Boot 2011.03, although this pre-dates sandbox and I have not tested it on real hardware.

2014-06-05Fix hush to give the correct return code for a simple commandSimon Glass1-1/+3
When a simple command like 'false' is provided, hush should return the result of that command. However, hush only does this if the FLAG_EXIT_FROM_LOOP flag is provided. Without this flag, hush will happily execute the empty string command immediate after 'false' and then return a success code. This behaviour does not seem very useful, and requiring the flag also seems wrong, since it means that hush will execute only the first command in a sequence. Add a check for empty string and fall out of the loop in that case. That at least fixes the simple command case. This is a change in behaviour but it is unlikely that the old behaviour would be considered correct in any case.
