When I mounted nfs on my target, the kernel crashed. And I found it was caused by stack overflow. When I digged into it. I found the following issue. In the file "./uClibc/libc/inet/rpc/auth_unix.c" int max_nr_groups = sysconf (_SC_NGROUPS_MAX); gid_t gids[max_nr_groups]; And, NGROUPS_MAX is defined in the file "./linux-2.6.x/include/linux/limits.h" #define NGROUPS_MAX 65536 /* supplemental group IDs are available */ OK, here we can know max_nr_groups is assigned to 65536, that means a huge matrix "gids[65536] is in the function **authunix_create_default**. My method is doing it by malloc, the patch as follows.
