2014-04-08ldso: fix standalone execution on x86_64 architectureCédric VINCENT
If the dynamic linker is built with LDSO_STANDALONE_SUPPORT=y, it can load then run a dynamically linked program when explicitly invoked from the command line. This is used for test and prelink purposes, and also by other tools like PRoot to force the kernel to load the right ELF interpreter. This feature is currently broken on x86_64 since the number of command line arguments (ie. argc) passed from the kernel is an "elf_addr_t" (64 bit on x86_64), whereas it is read as an "unsigned int" (32 bit on x86_64).

2014-04-01Fix warnings in MIPS buildSteve Ellcey
This patch fixes the rest of the set-but-not-used warnings in the MIPS code by using attribute_unused and also fixes some conversion warnings by changing __arch_compare_and_exchange_xxx_[8|16]_int. Assigning __cmp (int type) to __prev (pointer type) generates a warning. Assigning zero to each separately avoids this warning without having to add a cast.

2014-02-15mips: Remove duplicate macro definitionsSteve Ellcey
The INLINE_SYSCALL, INTERNAL_SYSCALL*, and internal_syscall* macros are defined for MIPS in both libc/sysdeps/linux/mips/sysdep.h and libc/sysdeps/linux/mips/bits/syscalls.h. The macros are the same in both cases except that syscalls.h defines internal_syscalls[567] the same for N32 and N64 ABIs and has a different definition for O32. I believe that is correct. The sysdep.h header uses the O32 versions for N32 and has different definitions for N64. I think that is wrong and that N32 and N64 should share the same definition (modulo the type 'long' vs. 'long long' for the arguments. This setup (from sysdep.h) now agrees with what glibc has. I am not positive about which header (sysdep.h vs syscalls.h) is really the right one to have these definitions in but using sysdep.h seems to work for all my builds.

2014-02-15libc: Fix sync_file_range.c for MIPS64 N32 ABISteve Ellcey
The special sync_file_range handling is only needed for the O32 ABI (regardless of whether it is on mips32 or mips64). The N32 (and N64) ABI's should both use the standard code. This routine was using the special code for the N32 ABI because that ABI has a word size of 32 bits and that is wrong. This patch fixes it by checking the ABI used instead of checking the word size.

2014-02-02libc: mips: Fix setjmp/longjmp for MIPS64 N64 ABIWaldemar Brodkorb
When booting a Linux system with qemu-system-mips64 the execution of $(pwd) in the ash shell triggers a segmentation fault. Ash uses setjmp/longjmp for exception handling. After looking at the glibc implementation, I found some differences, with this patch tries to resolve. Now the system boots up fine and no segmentation faults occur. The global pointer should be restored and the types for the register values should be wide enough.

2014-01-22vfork: fix clone based versionStefan Kristiansson
The clone based version was introduced by commit 58570fc8e1fd601f15be5758ab95013d56771804 vfork: Use clone if arch does not have the vfork syscall but the code was made unreachable by the previous commit 0a043c30ee71245dfe7c9d82d654312c5e1f6127 vfork: make all archs consistent that adds a guard which require either __NR_vfork or __NR_fork to be set. Neither will be set on an arch that would need to use the clone based version. The double declaration of vfork was also introduced by the merge of the two above mentioned patches. The missing ; was present in the original patch. CC: Markos Chandras <markos.chandras@imgtec.com> CC: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com> CC: Peter S.

2014-01-22libc: fix MIPS N64 forkWaldemar Brodkorb
fork() is broken for MIPS64 N64 ABI. You can check it with a simple C program statically linked with qemu-mips64 user emulation. Internally fork() is using the clone system call (at least with NPTL) with 5 arguments. See ./libpthread/nptl/sysdeps/unix/sysv/linux/i386/fork.c. The calling conventions for MIPS N32 and N64 allow to use up to 8 registers for that. See http://en.wikipedia.org/wiki/Calling_convention#MIPS This is correctly implemented in libc/sysdeps/linux/mips/bits/syscalls.h, but not in libc/sysdeps/linux/mips/sysdep.h. fork.c uses the later one. It seems that fork() works fine for MIPS64 N32 with just using the stack like with the O32 case. There is a user of INLINE_SYSCALL with 7 arguments in libc/sysdeps/linux/common/sync_file_range.c for MIPS64 N32, so I decided to only use the macros for the MIPS64 N64 case. With this patch my uClibc based Linux system boots up fine in qemu-system-mips64. Signed-off-by: Waldemar Brodkorb <wbx@openadk.org> Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>

2013-12-20inet: Fix threaded res_initKenneth Soerensen
In a multi-threaded application where res_init() was called either directly or implicitly, getaddrinfo() and others failed to add the DNS search domain to hostnames. This problem made it not possible to look up a hostname without its domain appended. The problem is caused by res_sync_func() overwriting the configuration read by __open_nameservers() immediately after it is read. The suggested solutin is to disable res_sync_func() while reading name server configuration in res_init().
