    Subjectexecve exit status on MIPS
    Date

    Hi all,

    Please find the below testcase..

    #include <stdio.h>
    #include <limits.h>
    #include <errno.h>
    #include <unistd.h>
    #include <stdlib.h>
    #include <string.h>
    #include <sys/types.h>
    #include <sys/stat.h>

    #define EXE_NAME "./exe"

    char e2BIG[ARG_MAX+1][10];
    char *envList[]={NULL};

    int main(void)
    {
    int ret,ind;

    for(ind = 0; ind < ARG_MAX+1; ind++)
    strcpy(e2BIG[ind], "helloworld");

    if ((ret = chmod(EXE_NAME,0744)) != 0){
    printf("chmod failed\n");
    exit(1);
    }

    /* whne arg list is too long */
    if ((ret = execve(EXE_NAME,e2BIG,envList)) == -1) {
    if ( errno == E2BIG)
    printf("Test Pass\n");
    else
    printf("Test Fail : Got Errno %d\n", errno);
    exit(0);
    }
    else
    printf("execve worked out of limit\n");
    exit(1);
    }


    On MIPS E2BIG is not getting set as errno instead EFAULT is set, while on
    other archs like ARM, PowerPC and i686 I am able to get E2BIG.

    Please let me know about the issue...

    Let EXE_NAME be any executable....

    Thanks,
    Halesh
