| | | | | | | | | | | | | | | | Rather than copy more code back into the bridge-utilities, how about applying this change to uClibc? I hate when packages get cluttered for workarounds for other incompatibilities. The problem is that SIOCGIFCONF only lists interfaces that have IP addresses, so it doesn't find the other interfaces that are being used for bridging. It could be fixed in the kernel to return all interfaces, but then something else might break; and still it mean a kernel update for the 2.4 users. The whole use of ifindex in the bridge API is a bad idea. But we probably have to live with it for compatibility. Patch against uClibc 0.9.26

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Hello, I managed to get ldso (and thus shared linking to uClibc) to work on sparc (actually sparc64 kernel with 32-bit userspace), at least on simple "hello world" program (more complex ones not tested). Some notes on attached patch (against 0.9.26, would require some work to apply on current CVS - but I tested 0.9.26, not CVS): - ELF magic cannot be examined by _dl_strncmp so early, probably because of string constant, like on ppc/mips/sh (note that early SEND_STDERR still crashes when trying to do _dl_strlen - I suppose that string constants require relocation; but adding load_addr didn't help, just ELF header was displayed instead of crash) - mmap() is syscall6 like on ppc/mips/sh, not old i386 mmap() - for generic sparc (i.e. not sparcv8/sparcv9) gcc produces .udiv/.urem calls for unsigned integer / and % operators - so these operations must be avoided. I copied do_rem definition from arm header. But / and % are used also in _dl_simple_ltoa() and _dl_simple_ltoahex(); in ltoahex gcc optimizes it to shifts (but I think it's safer to use shifts explicitly, not rely on optimization...). I changed % in ltoa to do_rem, but as there was no do_div definition, I changed all "%d" specifiers to "%x" to avoid crashes (this changes wouldn't be needed if _dl_simple_ltoa() were fixed to not use division on sparc). - "#define SOLARIS_COMPATIBLE" in ld_sysdep.h broke ldso on Linux because of redefining _dl_linux_resolve only in some places (it was still referenced in INIT_GOT before redefinition). So _dl_linux_resolve redefinition should be moved before INIT_GOT definition or removed. - sparc64 kernel requires mmap() addresses to be aligned to 8192, not 4096, otherwise mmap() call failed - reloc_entry must be shifted by 10, not 12 (I found similar operation in glibc sources) Aside of sparc-specific fixes: - I moved some _dl_dprintf()s inside if(_dl_debug_*) conditions (to avoid debugging messages when LD_DEBUG is not defined) - it seems that there was possible off-by-one in ltoa and ltoahex? they are called with char[22] as 1st argument, and then '\0' is stored in local[22] (_before_ p decrementation)... or am I missing something? If not, fix is included in patch.

| | | | | | | | | | | 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

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Here are a number of minor changes to FR-V-specific bits of the uClibc port: - I've adjusted the definition of _dl_mmap to cope with the fact that there will be a definition for an mmap2-only system. - We don't have COPY relocs, so optimize the copy reloc-related code away. - Change the page size to 16KiB, to match the ABI spec, and not a stale value I'd copied from a linker config file. Oops. - Fix error handling in clone and vfork; parts of the changes by David Howells <dhowells@redhat.com> - Rearrange includes in crtreloc.c. - Change the API of __syscall_error, to reduce code size. - Improve __syscall_return in terms of code size, so as to enable tail-calling of __syscall_error, at least within libc. Ideally, __syscall_error should be hidden within libc.so, but this didn't work because of libdl. I haven't looked into why, and figured I'd leave it visible for now. - Rename enumerators and macros in sys/ucontext.h to reduce namespace pollution.

| | | | | | | | | A program that requests __pthread_sig_debug to be blocked will self-deadlock when it requests a thread to be created, because the debugger (rda or gdb) will never get the signal, so it won't wake up the pthread manager as expected. This patch fixes it.

| | | | | | | If I change that ELF_RTYPE_CLASS_COPY to ELF_RTYPE_CLASS_PLT to tell _dl_find_hash to ignore stubs when resolving undefined functions without stubs, the dlopen tests all pass. dlopen gets a pointer to the libc.so malloc instead of a pointer to the libpthread malloc stub. Yay! :-)

| | | | | | | | | | | | | | | | The vfork() wrapper defined in libpthread, that's used to run pthread_atfork()-registered handlers, is not only a very bad idea, it's broken and useless. Here's the rationale: [---------snip----------] Since the implementation as it stands is broken (linking a program that vfork()s and exec()s on the child and wait()s on the parent works unless you happen to link with libpthread), and I can't think of any workable solution, I suggest that we simply remove the vfork() overrider in the non-MMU case. Yes, we might lose some small amount of functionality here, but it's not like people running uClinux expect anything resembling actual fork() to work.

| | | | | | | | | | Because variables are linked to fixed registers, there is a problem in : (*__errno_location())=(-_r0); As __errno_location() uses r0 to return the address of the errno location, the negated address will be assigned instead of the error code. Attached patch will resolve this.
