* Finish move of clock_* functions to libc. [BZ #24959]Zack Weinberg2019-09-044-10/+10
| | | | | | | | | | | | | | | | 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/.

* Refactor sigcontextinfo.hAdhemerval Zanella2019-08-232-62/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Myers2019-08-152-0/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Weimer2019-07-023-5/+1
| | | | | | | | | | | | | | | | | | | | | 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.

* Remove obsolete, never-implemented XSI STREAMS declarationsFlorian Weimer2019-03-142-2/+0
| | | | | | | | | | | | | | | | | | | The stub implementations are turned into compat symbols. Linux actually has two reserved system call numbers (for getpmsg and putpmsg), but these system calls have never been implemented, and there are no plans to implement them, so this patch replaces the wrappers with the generic stubs. According to <https://bugzilla.redhat.com/show_bug.cgi?id=436349>, the presence of the XSI STREAMS declarations is a minor portability hazard because they are not actually implemented. This commit does not change the TIRPC support code in sunrpc/rpc_svcout.c. It uses additional XTI functionality and therefore never worked with glibc. Reviewed-by: Carlos O'Donell <carlos@redhat.com>

* io: Consolidate lockf implementationAdhemerval Zanella2019-02-151-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With internal fcntl64 internal (commit 06ab719d), it is possible to consolidate lockf implementation by using the LFS fcntl interface instead of using arch and system-specific implementations. For Linux, the i386 implementation is used as generic implementation by replacing the direct syscall with fcntl64 call. The LFS symbol alias for default LFS ABI (__OFF_T_MATCHES_OFF64_T) is used to avoid the duplicate symbol (instead of overriding the implementation with an empty file). For Hurd lockf64 semantic is changed: previous generic lockf64 implementation returned EOVERFLOW if LEN input is larger than 32-bit off_t. However, Hurd fcntl64 implementation for F_GETLK64, F_SETLK64, and F_SETLKW64 do accept off64_t inputs (__f_setlk accepts only off64_t inputs). Checked on i686-linux-gnu and x86_64-linux-gnu along with a i686-gnu build. * io/Makefile (tests): Add tst-lockf. * io/lockf.c (lockf): Use __fcntl and only define for !__OFF_T_MATCHES_OFF64_T. * io/lockf64.c (__lockf64): Call __fcntl64 and alias to lockf for __OFF_T_MATCHES_OFF64_T case. * io/tst-lockf.c: New file. * sysdeps/unix/sysv/linux/i386/lockf64.c: Remove file. * sysdeps/unix/sysv/linux/arm/lockf64.c: Likewise. * sysdeps/unix/sysv/linux/m68k/lockf64.c: Likewise. * sysdeps/unix/sysv/linux/mips/mips32/lockf64.c: Likewise. * sysdeps/unix/sysv/linux/mips/mips64/n32/lockf64.c: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc32/lockf64.c: Likewise. * sysdeps/unix/sysv/linux/s390/s390-32/lockf64.c: Likewise. * sysdeps/unix/sysv/linux/sh/lockf64.c: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc32/lockf64.c: Likewise.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit b4a5d26d883 (linux: Consolidate sigaction implementation) added a wrong kernel_sigaction definition for m68k, meant for __NR_sigaction instead of __NR_rt_sigaction as used on generic Linux sigaction implementation. This patch fixes it by using the Linux generic definition meant for the RT kernel ABI. Checked the signal tests on emulated m68-linux-gnu (Aranym). It fixes the faulty signal/tst-sigaction and man works as expected.

(It used to be used in defining other macros related to accept4 / recvmmsg / sendmmsg availability, but the code in that area was simplified once we could assume a kernel with those features, whether through a syscall or through socketcall, so allowing those functions to be handled much like other socket operations, without requring __ASSUME_SOCKETCALL.)

* Unify more sys/procfs.h headers.Joseph Myers2018-09-253-125/+59
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch continues the process of unifying sys/procfs.h headers for architectures using the Linux kernel. A bits/procfs-id.h header is added to define __pr_uid_t and __pr_gid_t for the types of pr_uid and pr_gid; the default version of this header uses unsigned int. On some architectures, sys/procfs.h has copies of 32-bit structures for 64-bit builds; those move into a bits/procfs-extra.h header (they can't go in bits/procfs.h because they have to come *after* other declarations from sys/procfs.h). Given appropriate versions of these headers, six more architectures can then move to providing only bits/procfs*.h without duplicating the rest of the contents of sys/procfs.h. Only alpha needs a further bits/ header to be added before it can stop having its own sys/procfs.h. Tested for x86_64 and x86, and with build-many-glibcs.py. * sysdeps/unix/sysv/linux/sys/procfs.h: Include <bits/procfs-id.h> and <bits/procfs-extra.h>. (struct elf_prpsinfo): Use __pr_uid_t and __pr_gid_t as types of pr_uid and pr_gid. * sysdeps/unix/sysv/linux/Makefile [$(subdir) = misc] (sysdep_headers): Add bits/procfs-id.h and bits/procfs-extra.h. * sysdeps/unix/sysv/linux/bits/procfs-extra.h: New file. * sysdeps/unix/sysv/linux/bits/procfs-id.h: Likewise. * sysdeps/unix/sysv/linux/arm/bits/procfs-id.h: Likewise. * sysdeps/unix/sysv/linux/arm/bits/procfs.h: Likewise. * sysdeps/unix/sysv/linux/m68k/bits/procfs-id.h: Likewise. * sysdeps/unix/sysv/linux/m68k/bits/procfs.h: Likewise. * sysdeps/unix/sysv/linux/s390/bits/procfs-extra.h: Likewise. * sysdeps/unix/sysv/linux/s390/bits/procfs-id.h: Likewise. * sysdeps/unix/sysv/linux/s390/bits/procfs.h: Likewise. * sysdeps/unix/sysv/linux/sh/bits/procfs-id.h: Likewise. * sysdeps/unix/sysv/linux/sh/bits/procfs.h: Likewise. * sysdeps/unix/sysv/linux/sparc/bits/procfs-extra.h: Likewise. * sysdeps/unix/sysv/linux/sparc/bits/procfs-id.h: Likewise. * sysdeps/unix/sysv/linux/sparc/bits/procfs.h: Likewise. * sysdeps/unix/sysv/linux/x86/bits/procfs-id.h: Likewise. * sysdeps/unix/sysv/linux/x86/bits/procfs.h: Likewise. * sysdeps/unix/sysv/linux/arm/sys/procfs.h: Remove file. * sysdeps/unix/sysv/linux/m68k/sys/procfs.h: Likewise. * sysdeps/unix/sysv/linux/s390/sys/procfs.h: Likewise. * sysdeps/unix/sysv/linux/sh/sys/procfs.h: Likewise. * sysdeps/unix/sysv/linux/sparc/sys/procfs.h: Likewise. * sysdeps/unix/sysv/linux/x86/sys/procfs.h: Likewise.
* Unify many bits/mman.h headers.Joseph Myers2018-09-181-44/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Many bits/mman.h headers for Linux architectures have exactly the same contents, up to whitespace, comments and the number of leading 0s on constants. Specifically, this applies to architectures that, in the Linux kernel, either have no uapi/asm/mman.h, or have one that includes asm-generic/mman.h without any changes or additions relevant to glibc (this last case is the one that applies to Arm). It's not useful to have to duplicate the set of MAP_* constants in glibc for all such architectures and any new architectures with that property. Thus, this patch creates a generic sysdeps/unix/sysv/linux/bits/mman.h and removes all the architecture-specific versions that become unnecessary. Further unification remains possible after this patch. For example, the new bits/mman.h could become bits/mman-map-flags-generic.h so that it could also be used by architecture-specific bits/mman.h headers on architectures that use the generic flags but add architecture-specific ones to them. That would allow this common set of MAP_* definitions to be used on ia64 and x86 as well (architectures that include asm-generic/mman.h from their own uapi/asm/mman.h but define additional MAP_* values of their own). Tested with build-many-glibcs.py. * sysdeps/unix/sysv/linux/bits/mman.h: New file. * sysdeps/unix/sysv/linux/aarch64/bits/mman.h: Remove. * sysdeps/unix/sysv/linux/arm/bits/mman.h: Likewise. * sysdeps/unix/sysv/linux/m68k/bits/mman.h: Likewise. * sysdeps/unix/sysv/linux/microblaze/bits/mman.h: Likewise. * sysdeps/unix/sysv/linux/nios2/bits/mman.h: Likewise. * sysdeps/unix/sysv/linux/riscv/bits/mman.h: Likewise. * sysdeps/unix/sysv/linux/s390/bits/mman.h: Likewise. * sysdeps/unix/sysv/linux/sh/bits/mman.h: Likewise.

* Fix Linux fcntl OFD locks for non-LFS architectures (BZ#20251)Adhemerval Zanella2018-06-262-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes the OFD ("file private") locks for architectures that support non-LFS flock definition (__USE_FILE_OFFSET64 not defined). The issue in this case is both F_OFD_{GETLK,SETLK,SETLKW} and F_{SET,GET}L{W}K64 expects a flock64 argument and when using old F_OFD_* flags with a non LFS flock argument the kernel might interpret the underlying data wrongly. Kernel idea originally was to avoid using such flags in non-LFS syscall, but since GLIBC uses fcntl with LFS semantic as default it is possible to provide the functionality and avoid the bogus struct kernel passing by adjusting the struct manually for the required flags. The idea follows other LFS interfaces that provide two symbols: 1. A new LFS fcntl64 is added on default ABI with the usual macros to select it for FILE_OFFSET_BITS=64. 2. The Linux non-LFS fcntl use a stack allocated struct flock64 for F_OFD_{GETLK,SETLK,SETLKW} copy the results on the user provided struct. 3. Keep a compat symbol with old broken semantic for architectures that do not define __OFF_T_MATCHES_OFF64_T. So for architectures which defines __USE_FILE_OFFSET64, fcntl64 will aliased to fcntl and no adjustment would be required. So to actually use F_OFD_* with LFS support the source must be built with LFS support (_FILE_OFFSET_BITS=64). Also F_OFD_SETLKW command is handled a cancellation point, as for F_SETLKW{64}. Checked on x86_64-linux-gnu and i686-linux-gnu.

The changes are mostly essentially the same as for the narrowing add functions, so the description of those generally applies to this patch as well. f32xmulf64 for i386 cannot use precision control as used for add and subtract, because that would result in double rounding for subnormal results, so that uses round-to-odd with long double intermediate result instead. The soft-fp support involves adding a new FP_TRUNC_COOKED since soft-fp multiplication uses cooked inputs and outputs.

With older binutils, it is included for MIPS o32 (despite the use of symbol versioning), and this means that all the ABI test baselines for MIPS o32 include "_gp_disp _gp_disp A". This symbol is not meaningfully part of the ABI for shared libraries, since it always has to be resolved at static link time to the local definition for the linked object. All the other absolute symbols in ABI test baselines are the names of symbol versions. I don't think the mere existence of a symbol version with a given name - as opposed to the contents of that version if nonempty - is part of the ABI either. Thus, this patch allows the ABI tests to pass both before and after the binutils change by changing abilist.awk not to include absolute symbols in its output, and changing the baselines accordingly.

* Consolidate alphasort{64} and versionsort{64} implementationAdhemerval Zanella2018-04-232-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch consolidates both alphasort{64} and versionsort{64} implementation on just the default dirent/alphasort{64}c and dirent/versionsort{64} respectively. It changes the logic to follow the conventions used on other code consolidation: * the non-LFS variant is only built for _DIRENT_MATCHES_DIRENT64 being 0. * the LFS variant is always built and aliased to getdents for ABIs that define _DIRENT_MATCHES_DIRENT64 to 1. Also on Linux the compat symbol for old non-LFS dirent64 definition requires a platform-specific scandir64.c. For powerpc32 and sparcv9 it requires to add specific arch-implementation to override the generic Linux one because neither ABI exports an compat symbol for non-LFS alphasort64 and versionsort64 variant. It is most likely a bug and it is also not one that can be fixed (in that there would be existing binaries expecting both meanings of that symbol at its single existing version, with binaries expecting the new meaning probably much more common than those expecting the original meaning of that symbol at that version). Checked on aarch64-linux-gnu, x86_64-linux-gnu, i686-linux-gnu, sparcv9-linux-gnu, sparc64-linux-gnu, powerpc-linux-gnu, and powerpc64le-linux-gnu. * dirent/alphasort.c (alphasort): Build iff _DIRENT_MATCHES_DIRENT64 is defined. * dirent/versionsort.c (versionsort): Likewise. * dirent/alphasort64.c (alphasort64): Build regardless and alias to alphasort if _DIRENT_MATCHES_DIRENT64 is defined. * dirent/versionsort64.c (versionsort64): Likewise. * sysdeps/unix/sysv/linux/i386/alphasort64.c: Remove file. * sysdeps/unix/sysv/linux/arm/alphasort64.c: Likewise. * sysdeps/unix/sysv/linux/arm/versionsort64.c: Likewise. * sysdeps/unix/sysv/linux/m68k/alphasort64.c: Likewise. * sysdeps/unix/sysv/linux/m68k/versionsort64.c: Likewise. * sysdeps/unix/sysv/linux/s390/s390-32/alphasort64.c: Likewise. * sysdeps/unix/sysv/linux/s390/s390-32/versionsort64.c: Likewise. * sysdeps/unix/sysv/linux/i386/versionsort64.c: Likewise. * sysdeps/unix/sysv/linux/alphasort64.c: New file. * sysdeps/unix/sysv/linux/versionsort64.c: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc32/alphasort64.c: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc32/versionsort64.c: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc32/alphasort64.c: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc32/versionsort64.c: Likewise.

* Consolidate Linux getdents{64} implementationAdhemerval Zanella2018-04-191-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch consolidates Linux getdents{64} implementation on just the default sysdeps/unix/sysv/linux/getdents{64}{_r}.c ones. Although this symbol is used only internally, the non-LFS version still need to be build due the non-LFS getdirentries which requires its semantic. The non-LFS default implementation now uses the wordsize-32 as base which uses getdents64 syscall plus adjustment for overflow (it allows to use the same code for architectures that does not support non-LFS getdents syscall). It has two main differences to wordsize-32 one: - DIRENT_SET_DP_INO is added to handle alpha requirement to zero the padding. - alloca is removed by allocating a bounded temporary buffer (it increases stack usage by roughly 276 bytes). The default implementation handle the Linux requirements: * getdents is only built for _DIRENT_MATCHES_DIRENT64 being 0. * getdents64 is always built and aliased to getdents for ABIs that define _DIRENT_MATCHES_DIRENT64 to 1. * A compat symbol is added for getdents64 for ABI that used to export the old non-LFS version.
