  • 54841ab50   Make sure that argv[] argument pointers are not modified. ... Browse Code »
    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) {
    ...

  • a89c33db9   General help message cleanup ... Browse Code »

    Many of the help messages were not really helpful; for example, many
    commands that take no arguments would not print a correct synopsis
    line, but "No additional help available." which is not exactly wrong,
    but not helpful either.

    Commit ``Make "usage" messages more helpful.'' changed this
    partially. But it also became clear that lots of "Usage" and "Help"
    messages (fields "usage" and "help" in struct cmd_tbl_s respective)
    were actually redundant.

    This patch cleans this up - for example:

    Before:
    => help dtt
    dtt - Digital Thermometer and Thermostat

    Usage:
    dtt - Read temperature from digital thermometer and thermostat.

    After:
    => help dtt
    dtt - Read temperature from Digital Thermometer and Thermostat

    Usage:
    dtt

  • 2fb2604d5   Command usage cleanup ... Browse Code »

    Remove command name from all command "usage" fields and update
    common/command.c to display "name - usage" instead of
    just "usage". Also remove newlines from command usage fields.

  • 9d4079955   Major PCMCIA Cleanup to make code better readable and maintainable. ... Browse Code »

    Notes:
    - Board-dependend code for RPXLITE and RPXCLASSIC-based boards
    placed to the drivers/rpx_pmcia.c file to avoid duplication.
    Same for TQM8xx-based boards (drivers/tqm8xx_pmcia.c).
    - drivers/i82365.c has been split into two parts located at
    board/atc/ti113x.c and board/cpc45/pd67290.c (ATC and CPC45 are
    the only boards using CONFIG_82365).
    - Changes were tested for clean build and *very* *few* boards.

    - add support for a new version of an Intracom board and fix
    various other things on others.
    - add verify support to the crc32 command (define
    CONFIG_CRC32_VERIFY to enable it)
    - fix FEC driver for MPC8xx systems:
    1. fix compilation problems for boards that use dynamic
    allocation of DPRAM
    2. shut down FEC after network transfers
    - HUSH parser fixes:
    1. A new test command was added. This is a simplified version of
    the one in the bourne shell.
    2. A new exit command was added which terminates the current
    executing script.
    3. Fixed handing of $? (exit code of last executed command)
