* Linux: Add tables with system call numbersFlorian Weimer2020-01-021-0/+310
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

* ipc: Refactor sysvipc internal definitionsAdhemerval Zanella2019-10-171-21/+0
| | | | | | | | | | | | | | | | | | | | | | | This patch refactor the internal sysvipc in two main points: 1. Add a new __ASSUME_SYSVIPC_DEFAULT_IPC_64 to infer the __IPC_64 value to be used along either the multiplexed __NR_ipc or wired-up syscall. The defaut value assumed for __IPC_64 is also changed from 0x100 to 0x0, aligning with Linux generic UAPI. The idea is to simplify the Linux 5.1 wire-up for sysvipc syscalls for some 32-bit ABIs (which expectes __IPC_64 being 0x0) and simplify new ports (which will no longer need to add ipc_priv.h). 2. It also removes some duplicated internal definition used on compat sysvipc symbols defined at ipc_priv.h (more specifically the __old_ipc_perm, SEMCTL_ARG_ADDRESS, MSGRCV_ARGS, and SEMTIMEDOP_IPC_ARGS). The idea is also to make it simpler to enable the new wire-up sysvipc syscall provided by Linux v5.1. There is no semantic change expected on any port. Checked with a build against all affected ABIs.

* Refactor sigcontextinfo.hAdhemerval Zanella2019-08-232-43/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch refactor sigcontextinfo.h header to use SA_SIGINFO as default for both gmon and debug implementations. This allows simplify profil-counter.h on Linux to use a single implementation and remove the requirements for newer ports to redefine __sigaction/sigaction to use SA_SIGINFO. The GET_PC macro is also replaced with a function sigcontext_get_pc that returns an uintptr_t instead of a void pointer. It allows easier convertion to integer on ILP32 architecture, such as x32, without the need to suppress compiler warnings. The patch also requires some refactor of register-dump.h file for some architectures (to reflect it is now called from a sa_sigaction instead of sa_handler signal context). - Alpha, i386, and s390 are straighfoward to take in consideration the new argument type. - ia64 takes in consideration the kernel pass a struct sigcontextt as third argument for sa_sigaction. - sparc take in consideration the kernel pass a pt_regs struct as third argument for sa_sigaction. - m68k dummy function is removed and the FP state is dumped on register_dump itself. - For SH the register-dump.h file is consolidate on a common implementation and the floating-point state is checked based on ownedfp field. The register_dump does not change its output format in any affected architecture. I checked on x86_64-linux-gnu, i686-linux-gnu, aarch64-linux-gnu, arm-linux-gnueabihf, sparcv9-linux-gnu, sparc64-linux-gnu, powerpc-linux-gnu, powerpc64-linux-gnu, and powerpc64le-linux-gnu. I also checked the libSegFault.so through catchsegv on alpha-linux-gnu, m68k-linux-gnu and sh4-linux-gnu to confirm the output has not changed.

* Make totalorder and totalordermag functions take pointer arguments.Joseph Myers2019-08-151-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Weimer2019-07-021-1/+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 gettid system call wrapper [BZ #6399]Florian Weimer2019-02-081-0/+1
| | | | | | | | | | This commit adds gettid to <unistd.h> on Linux, and not to the kernel-independent GNU API. gettid is now supportable on Linux because too many things assume a 1:1 mapping between libpthread threads and kernel threads. Reviewed-by: Carlos O'Donell <carlos@redhat.com>
