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>

2013-11-06Fix weak/strong attribute of __errno_location and it's __GI aliasVineet Gupta
A simple statically linked hello world program was segfaulting for ARC in linuxthreads.old configuration (although the root casue applies cross-arch for NPTL as well as linuxthreads.old as described) The crash was due to branch to NULL in _stdio_init 0001026c <_stdio_init>: 1026c: push_s blink 1026e: st.a r13,[sp,-8] 10272: bl.d 0 --> supposed call to __errno_location The call was NOT getting patched to libc internal only alias __GI___errno_location, because it was weak while it's exported cousin, __errno_location was strong/normal. arc-linux-uclibc-nm libc/misc/internals/__errno_location.os 00000000 W __GI___errno_location 00000000 T __errno_location This is exactly opposite to what is expected. Quoting Peter S. Mazinger, commit 87936cd013041 "errno and *_init cleanup" | The rule adopted: | for enabled threads we make in libc the __GI_x() variants strong, x() weak | and (should) provide another strong x() in libpthread. | If threads are disabled, even the __GI_x() variants are weak. With the fix, we see the right settings as below 00000000 T __GI___errno_location 00000000 W __errno_location Note that problem won't show up in a static busybox build as it references errno and that seems to elide the issue. I can confirm the same/more issues with latest ARM buildroot builds w/o my fix. (1). linuxthreads.old (broken just like ARC) arm-linux-nm uclibc-snapshot/libc/misc/internals/__errno_location.os 00000000 W __GI___errno_location 00000000 T __errno_location But presumably the issue there is NOT catestrophic because ARM linker is likely smarter and patches a NOP instead of NULL branch. 00008388 <_stdio_init>: 8388: e92d4038 push {r3, r4, r5, lr} 838c: e320f000 nop {0} (2) NPTL build (exported version is not weak) 00000000 T __GI___errno_location 00000000 T __errno_location This causes a static link with libpthread and test program referencing errno to fail to link. #include <errno.h> int main(void) { printf("%d\n", errno); } arm-linux-gcc -static -pthread -o tst tst.o arm-buildroot-linux-uclibcgnueabi/sysroot/usr/lib/libc.a(__errno_location.os): In function `__errno_location': __errno_location.c:(.text+0x0): multiple definition of `__errno_location' arm-buildroot-linux-uclibcgnueabi/sysroot/usr/lib/libpthread.a (errno_location.os):errno_location.c:(.text+0x0): first defined here Signed-off-by: Vineet Gupta <vgupta@synopsys.com> Cc: Baruch Siach <baruch@tkos.co.il> Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>

2013-07-04libc/sysdeps/linux/common/sendfile.c: fix sendfile64 visibilityAnthony G. Basile
Commit a83ea57a50 introduces code for falling back on sendfile64 when the sendfile syscall is not available. However, as written, that code leads to sendfile64 being globally hidden in situations where __NR_sendfile and __USE_LARGEFILE64 are defined. In this case, the flow executes strong_alias_untyped(sendfile,sendfile64) in libc/sysdeps/linux/common/sendfile.c and libc_hidden_proto(sendfile64) in include/sys/sendfile.h, but nowhere does it do libc_hidden_def(sendfile64).

2013-04-07linux: pread/write: fix 64bit handlingMike Frysinger
The syscall on 64bit ports takes 4 args as there is no need to split up the value into two args. Add support for that to the common code. Once we fix that, the mips code can now leverage it for its 64bit and 32bit needs. However, we can't just drop it entirely yet because its n32 ABI needs special handling to treat it like a 64bit port. This does change the existing behavior which treats the n32 like a 32bit port, but we want to do this. In the future, we'll probably have to introduce a define for this as it currently affects x86_64/x32 and mips/n32. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2013-04-01linux: pread/write: convert to SYSCALL_ALIGN_64BITMike Frysinger
The pread64/write64 syscalls have the 64bit register align issue for all arches. Use this new define so we can merge the powerc/xtensa versions back into the common code. SuperH is funky and also allows us to do this. We should be able to merge the mips version too, but that'll require someone to take a closer look as the current stuff doesn't look quite right.

2013-04-01linux: readahead: convert to SYSCALL_ALIGN_64BITMike Frysinger

2013-04-01mips: only define SYSCALL_ALIGN_64BIT for O32 ABIsMike Frysinger
The 64bit register alignment issue only affects the O32 ABI, so wrap the define accordingly. We don't want this being used for N32 ABIs.

2013-04-01libc: rename TRUNCATE64_HAS_4_ARGS to SYSCALL_ALIGN_64BITMike Frysinger

Since this alignment affects more than just truncate64, rename the define to properly document its purpose.
