* [BZ #17078] ARM: R_ARM_TLS_DESC prelinker supportMaciej W. Rozycki2014-07-173-5/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a change to the dynamic linker to add prelinker support for the R_ARM_TLS_DESC relocation. Two cases can be considered here, the usual one where lazy binding is in use and the less frequent one, where immediate binding is requested via the use of the DF_BIND_NOW dynamic flag (e.g. by using the GNU linker's "-z now" option). This change only handles the first case. In this scenario the prelinker does what the dynamic linker would do, that is it preinitialises R_ARM_TLS_DESC relocations with a pointer to the lazy specialization as provided with the DT_TLSDESC_PLT dynamic tag. A conflict is additionally created and in the conflict resolution path the dynamic linker complements the work by initialising the object's pointer as indicated by the DT_TLSDESC_GOT dynamic tag to the linker's internal lazy specialization worker function and also providing the associated link map in the second entry of the GOT. This step is required, because if prelinking is successful at the run time, then the dynamic linker's elf_machine_runtime_setup() function isn't called that would normally do so. The second case remains unresolved, because support for that scenario has not been implemented in the prelinker. In this case the lazy specialization is unavailable and the DT_TLSDESC_PLT dynamic tag is not present. The prelinker could assume the common case of static specialization and resolve the relocation, but that would require the exposure of dynamic linker's specialization worker function. Furthermore the dynamic linker would have to handle the relocation in the conflict resolution path and see if the dynamic specialization should be used instead. This however would require access to data structures currently not made available to the conflict resolution path and therefore a redesign of this part of the dynamic linker. Alternatively the prelinker could defer all processing to the dynamic linker's conflict resolution path, but that would require similar access to the said data structures. Therefore the prelinker issues an error instead and the dynamic linker has assertions to check that DT_TLSDESC_PLT and DT_TLSDESC_GOT are in use in its conflict resolution path. This change resolves all TLS failures in the prelinker testsuite, as noted in the bug report, as well as the small test case provided there. Unfortunately we don't seem to have any hooks to factor in the prelinker (if present on a system) to testing, so at this time this fix has to rely on using the prelinker test suite and enabling TLS descriptors there for coverage. [BZ #17078] * sysdeps/arm/dl-machine.h (elf_machine_rela) [RESOLVE_CONFLICT_FIND_MAP]: Handle R_ARM_TLS_DESC relocation. (elf_machine_lazy_rel): Handle prelinked R_ARM_TLS_DESC entries.

* Refactor handling of /lib64 etc. cases, move out of sysdeps/gnu/configure.ac.Joseph Myers2014-07-1718-132/+192
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch continues removing architecture-specific cases from non-architecture-specific files by moving the logic to use directories such as /lib64 out of sysdeps/gnu/configure.ac. A new macro LIBC_SLIBDIR_RTLDDIR is created that sysdeps configure scripts can use to declare the library directories to be used; the logic was previously duplicated in configure fragments for aarch64, mips and x32 as well as in sysdeps/gnu/configure.ac. This macro is used directly in sysdeps/gnu/configure.ac only to provide the /lib default (the logic saying that with --prefix=/usr shared libraries go in /lib not /usr/lib); the architecture cases formerly there are moved into various new or existing configure.ac files. The new macro is also used in the various architecture fragments that already had such logic. In the x32 there was previously a configure fragment, but it was a directly written one without a .ac file; now a .ac file is used there instead to generate configure. Tested x86_64 that the installed shared libraries, and the directory structure of the installation, are unchanged by this patch. There is an old bug report - bug 6441 - about library directories changing after reconfiguring. If this is still applicable - and I haven't attempted to confirm it or review the old patch pointed to in that bug - then this patch should reduce the number of places needing changing in any fix. * aclocal.m4 (LIBC_SLIBDIR_RTLDDIR): New macro. * sysdeps/gnu/configure.ac: Use LIBC_SLIBDIR_RTLDDIR. Remove cases for individual architectures. * sysdeps/gnu/configure: Regenerated. * sysdeps/unix/sysv/linux/aarch64/configure.ac: Use LIBC_SLIBDIR_RTLDDIR. * sysdeps/unix/sysv/linux/aarch64/configure: Regenerated. * sysdeps/unix/sysv/linux/mips/configure.ac: Use LIBC_SLIBDIR_RTLDDIR. * sysdeps/unix/sysv/linux/mips/configure: Regenerated. * sysdeps/unix/sysv/linux/powerpc/powerpc64/configure.ac: Use LIBC_SLIBDIR_RTLDDIR. * sysdeps/unix/sysv/linux/powerpc/powerpc64/configure: Regenerated. * sysdeps/unix/sysv/linux/s390/s390-64/configure.ac: New file. * sysdeps/unix/sysv/linux/s390/s390-64/configure: New generated file. * sysdeps/unix/sysv/linux/sparc/sparc64/configure.ac: New file. * sysdeps/unix/sysv/linux/sparc/sparc64/configure: New generated file. * sysdeps/unix/sysv/linux/x86_64/64/configure.ac: New file. * sysdeps/unix/sysv/linux/x86_64/64/configure: New generated file. * sysdeps/unix/sysv/linux/x86_64/x32/configure.ac: New file. * sysdeps/unix/sysv/linux/x86_64/x32/configure: Generate.
* Move architecture shlib-versions files to Linux-specific directories.Joseph Myers2014-07-1718-17/+49
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Various architectures have files such as sysdeps/<arch>/shlib-versions whose contents are in fact entirely Linux-specific, relating only to the symbol / shared library versions for the port to Linux on that architecture, when any future port to a different OS on that architecture would use the symbol version of the glibc release it goes in, as standard for new ports. This patch moves such files under sysdeps/unix/sysv/linux/, merging in the contents of sysdeps/<arch>/nptl/shlib-versions in the process. The only bits not moved are those relating to libgcc_s versions, which don't appear OS-specific in the same way that glibc's symbol versions so. It deliberately does not change the regular expressions given for matching configurations in each file; some match only Linux although not Linux-specific, or match other OSes although Linux-specific. It is with a view to at least the following further cleanups: * Move architecture-specific content from the toplevel shlib-versions and nptl/shlib-versions into sysdeps shlib-versions files, so eliminating another difference between ex-ports and non-ex-ports architectures. * Likewise, for OS-specific content in shlib-versions files. * At that point, the first field in shlib-versions files (the regular expression matching a configuration triplet) should be redundant, so eliminate that field and leave shlib-versions selection working purely on a sysdeps basis (with limited use of %ifdef in shlib-versions files when needed) rather than having its own separate mechanism to select what configuration information is relevant. * Move the build of gnu/lib-names.h to a similar mechanism to that used for gnu/stubs.h (each library build installing a version of the header specifically for that build), so we can eliminate the duplication of soname information in the makefiles and get it purely from shlib-versions files again. There may be other cleanups possible as well (in particular, I'm not sure that all cases where the same "Earliest symbol set" information is repeated for many different libraries actually should need to repeat it rather than specifying it just once for DEFAULT for the given configuration, and separately specifying any non-default choices of soname). Tested x86_64 that the installed shared libraries are unchanged by this patch. * sysdeps/aarch64/shlib-versions: Move to ... * sysdeps/unix/sysv/linux/aarch64/shlib-versions: ... here. * sysdeps/alpha/shlib-versions: Move to ... * sysdeps/unix/sysv/linux/alpha/shlib-versions: ... here. * sysdeps/arm/shlib-versions: Move to ... * sysdeps/unix/sysv/linux/arm/shlib-versions: ... here. * sysdeps/hppa/shlib-versions: Move all contents except for libgcc_s entry to ... * sysdeps/unix/sysv/linux/hppa/shlib-versions: ... here.

* iconv/loop.c: Fix -Wundef warning with !_STRING_ARCH_unalignedWill Newton2014-07-172-30/+34
| | | | | | | | | | | | | | | | | | If code is required to handle the unaligned case then loop.c includes itself and relies on the #undefs at the end of the file to avoid outputting two copies of LOOPFCT and gconv_btowc. However MAX_NEEDED_INPUT is tested with #if so this causes a warning. Reorder the code so that the function definitions are in an #else block to make the behaviour clearer and fix the warning. Verified that code is unchanged on x86_64 and arm. ChangeLog: 2014-07-17 Will Newton <will.newton@linaro.org> * iconv/loop.c: Move definition of LOOPFCT and gconv_btowc into an #else block.

| | | | | | | | | | | Here's an updated patch to fix the crash in bug-ga2 when the system has no configured ipv6 address. I have taken a different approach of using libc_freeres_fn instead of the libc_freeres_ptr since the former gives better control over what is freed; we need that since cache may or may not be allocated using malloc. Verified that bug-ga2 works correctly in both cases and does not have memory leaks in either of them.
