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.

2004-10-31Revert Peter's __lib_gettimeofday patch. There's the minor issue ofManuel Novoa III
adding cruft to include/sys/time.h. But also, there's no sense in making changes like this until we decide how we're going to approach the hidden symbol transition.

Hello! Would the attached patch be acceptable (maybe instead of __libc_gettimeofday using __gettimeofday) We have some issues, see http://bugs.gentoo.org/show_bug.cgi?id=65892

Hi Erik It seems to me that __pthread_once and __pthread_initialize_minimal could be made WEAKs with no stub. The code in rpc_thread.c and __uClibc_main.c appears to expect this. Also, __pthread_return_0 __pthread_return_1 and __pthread_return_void can be static, not to pollute the name space. Jocke

2004-03-18Based on a patch from Alexandre Oliva, remove all reference to 'bzero' (whichEric Andersen
is not a SuSv3 symbol). Rather than using __bzero internally per Alexandre's original patch, use memset instead.
2004-02-18Alexandre Oliva writes:Eric Andersen
While testing the FR-V code with GCC mainline, I ran into some problems in the RPC code. It relies on a GCC extension that is no longer available, namely, the result of a cast is no longer considered an lvalue. This patch enables the code to compile. I haven't been able to test RPC though, especially in a multi-threaded environment.

2003-12-27Fix a long-standing bug with pthreads. A couple of linuxthreads filesManuel Novoa III
were including libc-lock.h which had a bunch of weak pragmas. Also, uClibc supplied a number of no-op weak thread functions even though many weren't needed. This combined result was that sometimes the functional versions of thread functions in pthread would not override the weaks in libc. While fixing this, I also prepended double-underscore to all necessary weak thread funcs in uClibc, and removed all unused weaks. I did a test build, but haven't tested this since these changes are a backport from my working tree. I did test the changes there and no longer need to explicitly add -lpthread in the perl build for perl to pass its thread self tests.
