* nptl: Move pthread_cond_destroy implementation into libcFlorian Weimer2020-02-202-3/+0

* ld.so: Do not export free/calloc/malloc/realloc functions [BZ #25486]Florian Weimer2020-02-153-14/+0
| | | | | | | | | | | | | | | | | | | Exporting functions and relying on symbol interposition from libc.so makes the choice of implementation dependent on DT_NEEDED order, which is not what some compiler drivers expect. This commit replaces one magic mechanism (symbol interposition) with another one (preprocessor-/compiler-based redirection). This makes the hand-over from the minimal malloc to the full malloc more explicit. Removing the ABI symbols is backwards-compatible because libc.so is always in scope, and the dynamic loader will find the malloc-related symbols there since commit f0b2132b35248c1f4a80f62a2c38cddcc802aa8c ("ld.so: Support moving versioned symbols between sonames [BZ #24741]").

* linux: Remove INTERNAL_SYSCALL_DECLAdhemerval Zanella2020-02-142-4/+2
| | | | | | | | | | | With all Linux ABIs using the expected Linux kABI to indicate syscalls errors, the INTERNAL_SYSCALL_DECL is an empty declaration on all ports. This patch removes the 'err' argument on INTERNAL_SYSCALL* macro and remove the INTERNAL_SYSCALL_DECL usage. Checked with a build against all affected ABIs.
* powerpc: Consolidate Linux syscall definitionAdhemerval Zanella2020-02-141-194/+2
| | | | | | | | | | | | | | | | | | | | | | | | The diferences between powerpc64{le} and powerpc32 Linux sysdep.h are: 1. On both vDSO and syscall macros the volatile registers r9, r10, r11, and r12 are used as input operands on powerpc32 and as clobber registers on powerpc64. However the outcome is essentially the same, it advertise the register might be clobbered by the kernel (although Linux won't leak register information to userland in such case). 2. The LOADARGS* macros uses a different size to check for invalid types. 3. The pointer mangling support guard pointer loading uses ABI specific instruction and register. This patch consolidates on only one sysdep by using the the powerpc64 version as default and add the adjustments required for powerpc32. Checked on powerpc64-linux-gnu, powerpc64le-linux-gnu, and powerpc-linux-gnu-power4.
* powerpc64: Add memory protection key support [BZ #23202]Florian Weimer2020-02-143-0/+145
| | | | | | | | | The 32-bit protection key behavior is somewhat unclear on 32-bit powerpc, so this change is restricted to the 64-bit variants. Flag translation is needed because of hardware differences between the POWER implementation (read and write flags) and the Intel implementation (write and read+write flags).
* Linux: Add tables with system call numbersFlorian Weimer2020-01-021-0/+390
| | | | | | | | | | | | | | | | | | | | | | | | | | | The new tables are currently only used for consistency checks with the installed kernel headers and the architecture-independent system call names table. They are based on Linux 5.4. The goal is to use these architecture-specific tables to ensure that system call wrappers are available irrespective of the version of the installed kernel headers. The tables are formatted in the form of C header files so that they can be used directly in an #include directive, without external preprocessing. (External preprocessing of a plain table file would introduce cross-subdirectory dependency issues.) However, the intent is that they can still be treated as tables and can be processed by simple tools. The irregular system call names on 32-bit arm add a complication. The <fixup-asm-unistd.h> header is introduced to work around that, and the system calls are listed under regular names in the <arch-syscall.h> file. A make target, update-syscalls-list, is added to patch the glibc sources with data from the current kernel headers. Reviewed-by: Siddhesh Poyarekar <siddhesh@sourceware.org>

* Finish move of clock_* functions to libc. [BZ #24959]Zack Weinberg2019-09-042-5/+5
| | | | | | | | | | | | | | | | In glibc 2.17, the functions clock_getcpuclockid, clock_getres, clock_gettime, clock_nanosleep, and clock_settime were moved from librt.so to libc.so, leaving compatibility stubs behind. Now that the dynamic linker no longer insists on finding versioned symbols in the same library that originally defined them, we do not need the stubs anymore, and this means we don't need GLIBC_PRIVATE __-prefix aliases for most of the functions anymore either. (clock_gettime still needs one.) For ports added before 2.17, libc.so needs to provide two symbol versions for each, the default at GLIBC_2.17 plus a compat version matching what librt had. While I'm at it, move the clock_*.c files and their tests from rt/ to time/.

* Make totalorder and totalordermag functions take pointer arguments.Joseph Myers2019-08-152-0/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The resolution of C floating-point Clarification Request 25 <http://www.open-std.org/jtc1/sc22/wg14/www/docs/n2397.htm#dr_25> is that the totalorder and totalordermag functions should take pointer arguments, and this has been adopted in C2X (with const added; note that the integration of this change into C2X is present in the C standard git repository but postdates the most recent public PDF draft). This patch updates glibc accordingly. As a defect resolution, the API is changed unconditionally rather than supporting any sort of TS 18661-1 mode for compilation with the old version of the API. There are compat symbols for existing binaries that pass floating-point arguments directly. As a consequence of changing to pointer arguments, there are no longer type-generic macros in tgmath.h for these functions. Because of the fairly complicated logic for creating libm function aliases and determining the set of aliases to create in a given glibc configuration, rather than duplicating all that in individual source files to create the versioned and compat symbols, the source files for the various versions of totalorder functions are set up to redefine weak_alias before using libm_alias_* macros to create the symbols required. In turn, this requires creating a separate alias for each symbol version pointing to the same implementation (see binutils bug <https://sourceware.org/bugzilla/show_bug.cgi?id=23840>), which is done automatically using __COUNTER__. (As I noted in <https://sourceware.org/ml/libc-alpha/2018-10/msg00631.html>, it might well make sense for glibc's symbol versioning macros to do that alias creation with __COUNTER__ themselves, which would somewhat simplify the logic in the totalorder source files.) It is of course desirable to test the compat symbols. I did this with the generic libm-test machinery, but didn't wish to duplicate the actual tables of test inputs and outputs, and thought it risky to attempt to have a single object file refer to both default and compat versions of the same function in order to test them together. Thus, I created libm-test-compat_totalorder.inc and libm-test-compat_totalordermag.inc which include the generated .c files (with the processed version of those tables of inputs) from the non-compat tests, and added appropriate dependencies. I think this provides sufficient test coverage for the compat symbols without also needing to make the special ldbl-96 and ldbl-128ibm tests (of peculiarities relating to the representations of those formats that can't be covered in the generic tests) run for the compat symbols. Tests of compat symbols need to be internal tests, meaning _ISOMAC is not defined. Making some libm-test tests into internal tests showed up two other issues. GCC diagnoses duplicate macro definitions of __STDC_* macros, including __STDC_WANT_IEC_60559_TYPES_EXT__; I added an appropriate conditional and filed <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=91451> for this issue. On ia64, include/setjmp.h ends up getting included indirectly from libm-symbols.h, resulting in conflicting definitions of the STR macro (also defined in libm-test-driver.c); I renamed the macros in include/setjmp.h. (It's arguable that we should have common internal headers used everywhere for stringizing and concatenation macros.)

* nptl: Remove vfork IFUNC-based forwarder from libpthread [BZ #20188]Florian Weimer2019-07-022-4/+0
| | | | | | | | | | | | | | | | | | | | | With commit f0b2132b35248c1f4a80f62a2c38cddcc802aa8c ("ld.so: Support moving versioned symbols between sonames [BZ #24741]"), the dynamic linker will find the definition of vfork in libc and binds a vfork reference to that symbol, even if the soname in the version reference says that the symbol should be located in libpthread. As a result, the forwarder (whether it's IFUNC-based or a duplicate of the libc implementation) is no longer necessary. On older architectures, a placeholder symbol is required, to make sure that the GLIBC_2.1.2 symbol version does not go away, or is turned in to a weak symbol definition by the link editor. (The symbol version needs to preserved so that the symbol coverage check in elf/dl-version.c does not fail for old binaries.) mips32 is an outlier: It defined __vfork@@GLIBC_2.2, but the baseline is GLIBC_2.0. Since there are other @@GLIBC_2.2 symbols, the placeholder symbol is not needed there.
* Linux: Add getdents64 system callFlorian Weimer2019-06-072-0/+2

* ldbl-opt: Add error and error_at_line (bug 23984)Gabriel F. T. Gomes2019-03-012-0/+4
| | | | | | | | | | On platforms where long double may have the same format as double (-mlong-double-64), error and error_at_line do not take that into account and might produce wrong output if a long double conversion is requested by the format string ('%Lf'). This patch adds compatibility functions for this situation and redirects calls via header magic. Tested for powerpc, powerpc64 and powerpc64le.
* ldbl-opt: Add err, errx, verr, verrx, warn, warnx, vwarn, and vwarnx (bug 23984)Gabriel F. T. Gomes2019-03-012-0/+16
| | | | | | | | | | | | | | | When support for long double format with 128-bits (-mlong-double-128) was added for platforms where long double had the same format as double, such as powerpc, compatibility versions for the functions listed in the commit title were missed. Since the older format of long double can still be used (with -mlong-double-64), using these functions with a format string that requests the printing of long double variables will produce wrong outputs. This patch adds the missing compatibility functions and header magic to redirect calls to them when -mlong-double-64 is in use. Tested for powerpc, powerpc64 and powerpc64le.
* ldbl-opt: Add argp_error and argp_failure (bug 23983)Gabriel F. T. Gomes2019-03-012-0/+4

Tested for powerpc, powerpc64 and powerpc64le.
