2014-04-23test/math: Adjust arm tests for older ULPs formatGregory Fong
The ULPs format in glibc has changed slightly and now deviates from that in uClibc, so when using the files directly from glibc, for certain types of tests the ULPs values were incorrectly defaulting to 0 rather than using the values provided. This caused some tests to fail despite the max ULPs being correctly marked. Regenerated and updated part of the ULPs file to fix this issue. This also added values for exp and log.

These should have been protected by if (_dl_debug_reloc && _dl_debug_detail) , but since the previous change "ldso/mips: actually print results of each relocation" makes this redundant, just eliminate these prints instead.

2014-04-23weak symbols need to be "defined" weak but "declared" strongVineet Gupta
Patch "LT.old: Make __errno_location/__h_errno_location thread safe" uncovered yet another bug with static linking and errno (hopefully this is last of them all). Currently, __errno_location is declared weak but is defined strong. While this provides with the desired weak semantics in dso, it is subtly broken in static links. Quoting Joern Rennecke (ARC gcc expert): | I think the issue is that you declare the function as weak in the | header file. That is a rare instance where you want the reference | use declaration that differs a bit from the definition. | If the reference uses a weakly declared function, that creates a | weakref, i.e. the linker won't bother to look for this symbol at | all - if it gets linked in for some other reason, fine, | otherwise, it stays zero. So the solution to declare strong, define weak. Supporting data ----------------- orig code: ARM mmap wrapper (LT.old build + my prev patch for errno) _mmap: @ args = 8, pretend = 0, frame = 0 @ frame_needed = 0, uses_anonymous_args = 0 stmfd sp!, {r4, r5, r7, lr} ldr r5, [sp, #20] movs ip, r5, asl #20 beq .L2 bl __errno_location(PLT) mov r3, #22 str r3, [r0, #0] mvn r0, #0 ... ... .weak __errno_location A statically linked hello world program which uses mmap too. As we can see__errno_location is completely gone - which is semantically wrong - we need functional errno. 00008274 <__GI_mmap>: 8274: e92d40b0 push {r4, r5, r7, lr} 8278: e59d5014 ldr r5, [sp, #20] 827c: e1b0ca05 lsls ip, r5, #20 8280: 0a000004 beq 8298 8284: e320f000 nop {0} ^^^^^^^^^^ 8288: e3a03016 mov r3, #22 828c: e5803000 str r3, [r0] 8290: e3e00000 mvn r0, #0 This in turn is due to a fixup in ARM ld which transforms branch-to-null into a nop. It is better than crashing but still wrong since errno handling is removed. With the patch, errno_location is restored back in test program. 00008274 <__GI_mmap>: 8274: e92d40b0 push {r4, r5, r7, lr} 8278: e59d5014 ldr r5, [sp, #20] 827c: e1b0ca05 lsls ip, r5, #20 8280: 0a000004 beq 8298 <__GI_mmap+0x24> 8284: eb000010 bl 82cc <__errno_location> 8288: e3a03016 mov r3, #22 828c: e5803000 str r3, [r0] Cc: Christian Ruppert <christian.ruppert@abilis.com> CC: Francois Bedard <Francois.Bedard@synopsys.com> Cc: Anton Kolesov <Anton.Kolesov@synopsys.com> Cc: Joern Rennecke <joern.rennecke@embecosm.com> Cc: Jeremy Bennett <jeremy.bennett@embecosm.com> Cc: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Cc: Peter Korsgaard <peter@korsgaard.com> Cc: Khem Raj <raj.khem@gmail.com> Signed-off-by: Vineet Gupta <vgupta@synopsys.com> Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>
2014-04-23LT.old: Make __errno_location/__h_errno_location thread safeVineet Gupta
WHY: errno in uClibc is not thread safe HOW: __errno_location and it's sibling __h_errno_location need to be called via PLT - even from within libc. That way when linked with pthread, intra-uClibc callers will also use the thread safe version. This is achieved by removing the GI alias for these functions, ensuring that they get called normally (via PLT) Verified with ARC LT.old and ARM cubieboard2 buildroot (LT.old) NPTL is unaffected by this bug. ------------ History behind this patch --------------------- This is a long standing bug (https://bugs.busybox.net/show_bug.cgi?id=2089) Others have tried to fix it in past (alteast Peter Korsgaard's patch in 2010), but somehow failed to be merged (or were backed out afterwards). http://lists.uclibc.org/pipermail/uclibc/2010-July/044176.html One of the causes could be side effect of atleast one more bug related to pthreads and static link which has now been fixed. http://lists.uclibc.org/pipermail/uclibc/2013-October/047958.html I have solved this w/o looking at other pacthes but would like to give credit to Peter and others for confirming that it makes sense.

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).

2014-02-15mips: 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.

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.

2014-01-22libc: 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>
