2014-11-05Modify several tests to use test-skeleton.cArjun Shankar
This patch modifies several test cases to use test-skeleton.c. It was generated by a bash script written for this purpose and thus excludes several other tests which I deemed worth a visual inspection before making the change. I intend to follow up with individual patches to the tests skipped by the script. The script itself resides at http://git.io/WODAmg and should reproduce this very patch when run against master.

2014-11-05Don't use INTDEF/INTUSE with _dl_mcount (bug 14132).Joseph Myers
Continuing the removal of the obsolete INTDEF / INTUSE mechanism, this patch replaces its use for _dl_mcount with use of rtld_hidden_def / rtld_hidden_proto. Tested for x86_64 that installed stripped shared libraries are unchanged by the patch. [BZ #14132] * elf/dl-profile.c (_dl_mcount): Use rtld_hidden_def instead of INTDEF. * sysdeps/generic/ldsodefs.h (_dl_mcount_internal): Remove declaration.

2014-11-04Don't use INTDEF/INTUSE with _dl_init (bug 14132).Joseph Myers
Continuing the removal of the obsolete INTDEF / INTUSE mechanism, this patch eliminates its use for _dl_init. Since _dl_init was already declared with hidden visibility, creating a second hidden alias for it was completely pointless, so this patch replaces all uses of _dl_init_internal with plain _dl_init instead of using hidden_proto / hidden_def (which are only needed when you want a hidden alias for a non-hidden symbol; it's quite possible there are cases where they are used but don't need to be because the symbol in question is not part of the public ABI and is only used within a single library, so using attributes_hidden instead would suffice). Tested for x86_64 that installed stripped shared libraries are unchanged by the patch. [BZ #14132] * elf/dl-init.c (_dl_init): Don't use INTDEF. * sysdeps/aarch64/dl-machine.h (RTLD_START): Use _dl_init instead of _dl_init_internal. * sysdeps/alpha/dl-machine.h (RTLD_START): Likewise. * sysdeps/arm/dl-machine.h (RTLD_START): Likewise. * sysdeps/hppa/dl-machine.h (RTLD_START): Likewise. * sysdeps/i386/dl-machine.h (RTLD_START): Likewise. * sysdeps/ia64/dl-machine.h (RTLD_START): Likewise. * sysdeps/m68k/dl-machine.h (RTLD_START): Likewise. * sysdeps/microblaze/dl-machine.h (RTLD_START): Likewise. * sysdeps/mips/dl-machine.h (RTLD_START): Likewise. * sysdeps/powerpc/powerpc32/dl-start.S (_start): Likewise. * sysdeps/s390/s390-32/dl-machine.h (RTLD_START): Likewise. * sysdeps/s390/s390-64/dl-machine.h (RTLD_START): Likewise. * sysdeps/sh/dl-machine.h (RTLD_START): Likewise. * sysdeps/sparc/sparc32/dl-machine.h (RTLD_START): Likewise. * sysdeps/sparc/sparc64/dl-machine.h (RTLD_START): Likewise. * sysdeps/tile/dl-start.S (_start): Likewise. * sysdeps/x86_64/dl-machine.h (RTLD_START): Likewise. * sysdeps/x86_64/x32/dl-machine.h (RTLD_START): Likewise.
2014-11-04Don't use INTDEF/INTUSE with _dl_argv (bug 14132).Joseph Myers
Continuing the removal of the obsolete INTDEF / INTUSE mechanism, this patch replaces its use for _dl_argv with rtld_hidden_data_def and rtld_hidden_proto. Some places in .S files that previously used _dl_argv_internal or INTUSE(_dl_argv) now use __GI__dl_argv directly (there are plenty of existing examples of such direct use of __GI_*). A single place in rtld.c previously used _dl_argv without INTUSE, apparently accidentally, while the rtld_hidden_proto mechanism avoids such accidential omissions. As a consequence, this patch *does* change the contents of stripped ld.so. However, the installed stripped shared libraries are identical to those you get if instead of this patch you change that single _dl_argv use to use INTUSE, without any other changes. Tested for x86_64 (testsuite as well as comparison of installed stripped shared libraries as described above). [BZ #14132] * sysdeps/generic/ldsodefs.h (_dl_argv): Use rtld_hidden_proto. [IS_IN_rtld] (_dl_argv_internal): Do not declare. (rtld_progname): Make macro definition unconditional. * elf/rtld.c (_dl_argv): Use rtld_hidden_data_def instead of INTDEF.

2014-11-04soft-fp: Add _FP_TO_INT_ROUND.Joseph Myers
Continuing the series of patches adding soft-fp features from the kernel version of soft-fp to glibc so that glibc's version is able to replace the old fork of soft-fp in the kernel, this patch adds the last major such feature: _FP_TO_INT_ROUND, converting a floating-point number to an integer with rounding according to the current rounding direction (as opposed to truncating towards zero, which _FP_TO_INT does). The general structure of the implementation follows that of _FP_TO_INT, but of course is more complicated. As with glibc's _FP_TO_INT it works with raw input (the kernel versions of these macros predate the conversion of _FP_TO_INT and many other macros to raw or semi-raw input). I have not tried to work out what bugs there might be in the kernel version that this might fix; it's a from-scratch implementation based on _FP_TO_INT. Tested for powerpc (soft-float) that there is no change to the installed shared libraries; also tested with the libm tests with lrint / lrintf / llrint / llrintf made to use _FP_TO_INT_ROUND, to provide some test of the functionality. As we don't have benchmarks for those functions, I haven't actually included the soft-fp versions of them, although I expect them to be faster than the existing code (given that the existing code involves adding and subtracting numbers such as 0x1p52 to achieve the desired rounding, which is not particularly efficient when the underlying floating point is software floating point). 2014-11-04 Joseph Myers <joseph@codesourcery.com> * soft-fp/op-common.h (_FP_TO_INT_ROUND): New macro. * soft-fp/double.h [_FP_W_TYPE_SIZE < 64] (FP_TO_INT_ROUND_D): New macro.

Continuing the removal of unused __libc_* function names, this patch removes the __libc_nanosleep name. Tested for x86_64 (testsuite, and that the disassembly of installed shared libraries is unchanged by the patch; __nanosleep changes from weak to strong, which is of no significance). * posix/nanosleep.c (__libc_nanosleep): Rename to __nanosleep.

Concluding the move of syscall definitions to syscalls.list, where the removal of support for old kernel versions has made this possible, this patch removes C definitions of pread, pread64, pwrite and pwrite64 for powerpc64.

2014-10-30Remove __libc_creat function name.Joseph Myers
glibc has lots of __libc_* function names that no longer serve any purpose (are not used for any calls or exported at a public symbol version). This patch removes __libc_creat. It has the effect of creat becoming a strong symbol instead of a weak symbol in various cases, but that's fine; in shared libraries it doesn't matter at all, while for static linking the only other symbol sometimes defined in the same object is creat64, and whenever creat64 is a reserved name so is creat. Other such cases of unnecessary __libc_* symbols are expected to be dealt with in separate patches over time. Tested for x86_64 (testsuite, and that the disassembly of installed shared libraries is unchanged by the patch). * include/fcntl.h (__libc_creat): Remove declaration. * io/creat.c (__libc_creat): Rename to creat.

2014-10-28elf/dl-load.c: Use __strdup.Carlos O'Donell
During a refactoring pass several repeated blocks of code in dl-load.c were turned into a call to a local function named local_strdup. There is no need for local_strdup, and the routines should instead call __strdup. This change does just that. We call the internal symbol __strdup because calling strdup is unsafe. The user might be using a standard that doesn't include strdup and may have defined this symbol in their application. During a static link we might reference the user defined symbol and crash if it doesn't implement a standards conforming strdup. The resulting code is simpler to understand, and makes it easier to debug. No regressions on x86_64. 2014-10-28 Carlos O'Donell <carlos@redhat.com> * dl-load.c (local_strdup): Remove. (expand_dynamic_string_token): Use __strdup. (decompose_rpath): Likewise. (_dl_map_object): Likewise.

2014-10-24Move some chown / lchown / fchown definitions to syscalls.list (bug 14138).Joseph Myers
Continuing the move of syscall definitions to syscalls.list, where the removal of support for old kernel versions has made this possible, this patch moves various definitions of chown, lchown and fchown. In most cases the need for special syscalls.list entries (rather than existing generic ones) is because these architectures use chown32, lchown32 and fchown32 as syscall names. Some architectures also have symbol versioning compatibility for older versions of chown having been equivalent to lchown. The aliases specified for s390-32 had the effect of exporting __chown@@GLIBC_2.1 (but not __chown@GLIBC_2.0) despite it not being listed in Versions files. (I'm not sure why versioned_symbol but not compat_symbol were effective like that to create such __chown exports in the absence of Versions entries.) The natural way to preserve that versioned export of __chown seems to be to add it in a Versions file, so I did so. (Maybe actually it should be a compat symbol, __chown@GLIBC_2.1, unless there's a good reason for that export, but this patch doesn't change anything there.) Tested for x86.

2014-10-23hppa: Make __SIGRTMIN 32 (ABI break).Carlos O'Donell
In the Linux kernel version 3.17 the signal numbers were rearranged in order to make hppa like every other arch. Previously we started __SIGRTMIN at 37, and that meant several pieces of important software, including systemd, would fail to build. To support systemd we removed SIGEMT and SIGLOST, and rearranged the others according to expected values. This is technically an ABI incompatible change, but because zero applications use SIGSTKFLT, SIGXCPU, SIGXFSZ and SIGSYS nothing broke. Nothing uses SIGEMT and SIGLOST, and they were present for HPUX compatibility which is no longer supported. Thus because nothing breaks we don't do any compatibility work here.

2014-10-23Don't use INTDEF for powerpc32 compat symbols (bug 14132).Joseph Myers
Continuing the removal of the obsolete INTDEF / INTUSE mechanism, this patch removes the use of INTUSE to rename symbols in sysdeps/powerpc/powerpc32/libgcc-compat.S. As the names in question are purely internal to this particular object and not used anywhere else, it doesn't matter at all whether __*_v_glibc20 or __*_internal is used, so this patch just removes the macros in question. Tested for powerpc32 that stripped installed shared libraries are unchanged by this patch. [BZ #14132] * sysdeps/powerpc/powerpc32/libgcc-compat.S (__ashldi3_v_glibc20): Remove macro definition.

2014-10-22MIPS: Avoid a dangling `vfork@GLIBC_2.0' referenceMaciej W. Rozycki
This satisfies a symbol reference created with: .symver __libc_vfork, vfork@GLIBC_2.0 where `__libc_vfork' has not been defined or referenced. In this case the `vfork@GLIBC_2.0' reference is supposed to be discarded, however a bug present in GAS since forever causes an undefined symbol table entry to be created. This in turn triggers a problem in the linker that can manifest itself by link errors such as: ld: libpthread.so: invalid string offset 2765592330 >= 5154 for section `.dynstr' The GAS and linker bugs need to be resolved, but we can avoid them too by providing a `__libc_vfork' definition just like our other platforms. [BZ #17485] * sysdeps/unix/sysv/linux/mips/vfork.S (__libc_vfork): Define.
2014-10-21Don't use INTDEF with __ldexpf (bug 14132).Joseph Myers
