2015-06-29mtd, nand: Move common functions from cmd_nand.c to common placeHeiko Schocher
Move common functions from cmd_nand.c (for calculating offset and size from cmdline paramter) to common place, so they could used from other commands which use mtd partitions. For onenand the arg_off_size() is left in common/cmd_onenand.c. It should use now the common arg_off() function, but as I could not test onenand I let it there ...

2014-02-19cmd_test: implement -e test for file existenceStephen Warren
This is much like a regular shell's -e operator, except that it takes multiple arguments to specify the device type and device/partition ID in addition to the usual filename: if test -e mmc 0:1 /boot/boot.scr; then echo yes; else echo no; fi Signed-off-by: Stephen Warren <swarren@nvidia.com>
2014-02-19cmd_test: evaluate to false without any argumentsStephen Warren
This emulates bash: $ if test; then echo yes; else echo no; fi no Currently, the code sets expr = -1 in this case, which gets mapped to 0 (true) at the end of do_test() by the logical -> shell exit code conversion. Signed-off-by: Stephen Warren <swarren@nvidia.com>
2014-02-19cmd_test: implement ! on sub-expressionsStephen Warren
Currently, ! can only be parsed as the first operator in an expression. This prevents the following from working: $ if test ! ! 1 -eq 1; then echo yes; else echo no; fi yes $ if test ! 1 -eq 2 -a ! 3 -eq 4; then echo yes; else echo no; fi yes Fix this by parsing ! like any other operator, and and handling it similarly to -a and -o.

2014-02-19cmd_test: check for binary operators before unaryStephen Warren
This better mirrors the behaviour of bash, for example: $ if test -z = -z; then echo yes; else echo no; fi yes This is parsed as a string comparison of "-z" and "-z", since the check for the binary "=" operator occurs first. Without this change, the command would be parsed as a -z test of "-", followed by a syntax error; a trailing -z without and operand. This is a behavioural change, but I believe any commands affected were previously invalid or bizarely formed. Signed-off-by: Stephen Warren <swarren@nvidia.com>
2014-02-19cmd_test: use table lookup for parsingStephen Warren
do_test() currently uses strcmp() twice to determine which operator is present; once to determine how many arguments the operator needs, then a second time to actually decode the operator and implement it. Rewrite the code so that a table lookup is used to translate the operator string to an integer, and use a more efficient switch statement to decode and execute the operator. This approach also acts as enablement for the following patches. This patch should introduce no behavioural change. Signed-off-by: Stephen Warren <swarren@nvidia.com>

2010-07-04Make sure that argv[] argument pointers are not modified.Wolfgang Denk
The hush shell dynamically allocates (and re-allocates) memory for the argument strings in the "char *argv[]" argument vector passed to commands. Any code that modifies these pointers will cause serious corruption of the malloc data structures and crash U-Boot, so make sure the compiler can check that no such modifications are being done by changing the code into "char * const argv[]". This modification is the result of debugging a strange crash caused after adding a new command, which used the following argument processing code which has been working perfectly fine in all Unix systems since version 6 - but not so in U-Boot: int main (int argc, char **argv) { while (--argc > 0 && **++argv == '-') { /* ====> */ while (*++*argv) { switch (**argv) { case 'd': debug++; break; ... default: usage (); } } } ... } The line marked "====>" will corrupt the malloc data structures and usually cause U-Boot to crash when the next command gets executed by the shell. With the modification, the compiler will prevent this with an error: increment of read-only location '*argv' N.B.: The code above can be trivially rewritten like this: while (--argc > 0 && **++argv == '-') { char *arg = *argv; while (*++arg) { switch (*arg) { ...
