Hi tech@, The code framework of dmesg.c:
......
struct msgbuf cur;
char *allocated = NULL;
......
if (memf == NULL && nlistf == NULL) {
......
} else {
#ifndef NOKVM
......
#endif
}
if (cur.msg_bufx >= cur.msg_bufs)
cur.msg_bufx = 0;
......
free(allocated);
......
In reality, is there possible to have "NOKVM" defined (in else branch)?
If so, the "cur" variable will be messy, and "allocated" will be NULL.
Hope to check it, thanks!
