* Make sure that argv[] argument pointers are not modified.Wolfgang Denk2010-07-04-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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) { ...

* smc91111_eeprom: fix linking errorMike Frysinger2010-01-31-3/+2
| | | | | | | | | | | | | | Building for a bf533-stamp ends up with this error: smc91111_eeprom.o: In function `smc91111_eeprom': examples/standalone/smc91111_eeprom.c:58: undefined reference to `memset' make[2]: *** [smc91111_eeprom] Error 1 The new eth_struct definition means gcc has to zero out the structure on the stack, and some gcc versions optimize this with an implicit call to memset. So tweak the structure style to avoid that gcc feature. Signed-off-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Ben Warren <biggerbadderben@gmail.com>
* Fix breakage in SMC EEPROM standalone applicationsBen Warren2010-01-19-2/+0
| | | | | | | | | | Commit 6a45e384955262882375a2785426dc65aeb636c4 (Make getenv_IPaddr() global) inadvertently added ' #include "net.h" ' to the standalone programs, creating duplicate definitions of 'struct eth_device'. This patch removes the local definitions and removes other code that breaks due to the change in definition.
