* ld.so: Do not export free/calloc/malloc/realloc functions [BZ #25486]Florian Weimer2020-02-152-10/+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 Zanella2020-02-145-27/+23
| | | | | | | | | | | With all Linux ABIs using the expected Linux kABI to indicate syscalls errors, the INTERNAL_SYSCALL_DECL is an empty declaration on all ports.

| | | | | | | | | | | | | | It highly unlikely that alpha will be ported to anything else than Linux, so this patch moves the generic unix syscall definition to Linux and adapt it to Linux kernel ABI.

* Linux: Use system call tables during buildFlorian Weimer2020-01-022-30/+0
| | | | | | | | | | | | | | | | | | | | | | | Use <arch-syscall.h> instead of <asm/unistd.h> to obtain the system call numbers. A few direct includes of <asm/unistd.h> need to be removed (if the system call numbers are already provided indirectly by <sysdep.h>) or replaced with <sys/syscall.h>. Current Linux headers for alpha define the required system call names, so most of the _NR_* hacks are no longer needed. For the 32-bit arm architecture, eliminate the INTERNAL_SYSCALL_ARM macro, now that we have regular system call names for cacheflush and set_tls. There are more such cleanup opportunities for other architectures, but these cleanups are required to avoid macro redefinition errors during the build. For ia64, it is desirable to use <asm/break.h> directly to obtain the break number for system calls (which is not a system call number itself). This requires replacing __BREAK_SYSCALL with __IA64_BREAK_SYSCALL because the former is defined as an alias in <asm/unistd.h>, but not in <asm/break.h>.

* Linux: Add tables with system call numbersFlorian Weimer2020-01-021-0/+469
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

* Use clock_gettime to implement gettimeofday.Adhemerval Zanella2019-10-303-3/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Consolidate generic gettimeofday implementation to use clock_gettime. Linux ports that still provide gettimeofday through vDSO are not changed. Remove sysdeps/unix/clock_gettime.c, which implemented clock_gettime using gettimeofday; new OS ports must provide a real implementation of clock_gettime. Rename sysdeps/mach/gettimeofday.c to sysdeps/mach/clock_gettime.c and convert into an implementation of clock_gettime. It only supports CLOCK_REALTIME; Mach does not appear to have any support for monotonic clocks. It uses __host_get_time, which provides at best microsecond resolution. Hurd is currently using sysdeps/posix/clock_getres.c for clock_getres; its output for CLOCK_REALTIME is based on sysconf (_SC_CLK_TCK), and I do not know whether that gives the correct result. Unlike settimeofday, there are no known uses of gettimeofday's vestigial "get time zone" feature that are not bugs. (The per-process timezone support in localtime and friends is unrelated, and the programs that set the kernel's offset between the hardware clock and UTC do not need to read it back.) Therefore, this feature is dummied out. Henceforth, if gettimeofday's "struct timezone" argument is not NULL, it will write zeroes to both fields. Any program that is actually looking at this data will thus think it is running in UTC, which is probably more correct than whatever it was doing before. [__]gettimeofday no longer has any internal callers, so we can now remove its internal prototype and PLT bypass aliases. The __gettimeofday@GLIBC_2.0 export remains, in case it is used by any third-party code. It also allows to simplify the arch-specific implementation on x86 and powerpc to remove the hack to disable the internal route to non iFUNC variant for internal symbol. This patch also fixes a missing optimization on aarch64, powerpc, and x86 where the code used on static build do not use the vDSO. Checked on x86_64-linux-gnu, i686-linux-gnu, powerpc64le-linux-gnu, powerpc64-linux-gnu, powerpc-linux-gnu, and aarch64-linux-gnu.

* Use clock_settime to implement settimeofday.Zack Weinberg2019-10-304-3/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Unconditionally, on all ports, use clock_settime to implement settimeofday. Remove sysdeps/unix/clock_settime.c, which implemented clock_settime by calling settimeofday; new OS ports must henceforth provide a real implementation of clock_settime. Hurd had a real implementation of settimeofday but not of clock_settime; this patch converts it into an implementation of clock_settime. It only supports CLOCK_REALTIME and microsecond resolution; Hurd/Mach does not appear to have any support for finer-resolution clocks. The vestigial "set time zone" feature of settimeofday complicates the generic settimeofday implementation a little. The only remaining uses of this feature that aren't just bugs, are using it to inform the Linux kernel of the offset between the hardware clock and UTC, on systems where the hardware clock doesn't run in UTC (usually because of dual-booting with Windows). There currently isn't any other way to do this. However, the callers that do this call settimeofday with _only_ the timezone argument non-NULL. Therefore, glibc's new behavior is: callers of settimeofday must supply one and only one of the two arguments. If both arguments are non-NULL, or both arguments are NULL, the call fails and sets errno to EINVAL. When only the timeval argument is supplied, settimeofday calls __clock_settime(CLOCK_REALTIME), same as stime. When only the timezone argument is supplied, settimeofday calls a new internal function called __settimezone. On Linux, only, this function will pass the timezone structure to the settimeofday system call. On all other operating systems, and on Linux architectures that don't define __NR_settimeofday, __settimezone is a stub that always sets errno to ENOSYS and returns -1. The settimeoday syscall is enabled on Linux by the flag COMPAT_32BIT_TIME, which is an option to either 32-bits ABIs or COMPAT builds (defined usually by 64-bit kernels that want to support 32-bit ABIs, such as x86). The idea to future 64-bit time_t only ABIs is to not provide settimeofday syscall. The same semantics are implemented for Linux/Alpha's GLIBC_2.0 compat symbol for settimeofday. There are no longer any internal callers of __settimeofday, so the internal prototype is removed.

* Linux/Alpha: don't use timeval32 system calls.Zack Weinberg2019-10-3013-96/+575
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Linux/Alpha has two versions of several system call wrappers that take or return data of type "struct timeval" (possibly nested inside a larger structure). The GLIBC_2.0 version is a compat symbol that calls __NR_osf_foo or __NR_old_foo and uses a struct timeval with a 32-bit tv_sec field. The GLIBC_2.1 version is used for current code, calls __NR_foo, and uses a struct timeval with a 64-bit tv_sec field. This patch changes all of the compat symbols of this type to be wrappers around their GLIBC_2.1 counterparts; the compatibility system calls will no longer be used. It serves as a proposal for part of how we do the transition to 64-bit time_t on systems that currently use 32-bit time_t: * The patched glibc will NOT use system calls that involve 32-bit time_t to implement its compatibility symbols. This will make both our lives and the kernel maintainers' lives easier. The primary argument I've seen against it is that the kernel could warn about uses of the old system calls, helping people find old binaries that need to be recompiled. I think there are several other ways we could accomplish this, e.g. scripts to scan the filesystem for binaries with references to the old symbol versions, or issuing diagnostics ourselves. * The compat symbols do NOT report failure after the Y2038 deadline. An earlier revision of this patch had them return -1 and set errno to EOVERFLOW, but Adhemerval pointed out that many of them have already performed side effects at the point where we discover the overflow, so that would break more than it fixes. Also, we don't want people to be _checking_ for EOVERFLOW from these functions; we want them to recompile with 64-bit time_t. So it's not actually useful for them to report failure to the calling code. * What they do do, when they encounter overflow, is saturate the overflowed "struct timeval"(s): tv_sec is set to INT32_MAX and tv_nsec is set to 999999. That means time stops advancing for programs with 32-bit time_t when they reach the deadline. That's obviously going to break stuff, but I think wrapping around is probably going to break _more_ stuff. I'd be interested to hear arguments against, if anyone has one. The new header file tv32-compat.h is currently Alpha-specific but I mean for it to be reused to aid in writing wrappers for all affected architectures. I only put it in sysdeps/unix/sysv/linux/alpha for now because I haven't checked whether the various "foo32" structures it defines agree with the ABI for ports other than Linux/Alpha.

| | | | | | | | | | | | | | | | | | | | | | | 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.

The changes required are as follow: 1. It moves the ipc_perm definition out of ipc.h to its own header ipc_perm.h. It also allows consolidate the IPC_* definition on only one header. 2. The generic implementation follow the kernel ipc64_perm size so the syscall can be made directly without temporary buffer copy. However, since glibc defines the MODE field as mode_t, it omits the __PAD1 field (since glibc does not export mode_t as 16-bit for any architecture). It is a two-fold improvement: 2.1. New implementation which follow Linux UAPI will not need to provide an arch-specific ipc-perm.h header neither wrongly use the wrong 16-bit definition from previous default ipc.h (as csky did). 2.1. It allows consolidate ipc_perm definition for architectures that already provide mode_t as 32-bit. 3. All kernel ABIs for the supported architectures already provides the expected padding for mode type extension to 32-bit. However, some architectures the padding has the wrong placement, so it requires the ipc control routines (msgctl, semctl, and shmctl) to adjust the mode field accordingly. Currently they are armeb, microblaze, m68k, s390, and sheb. A new assume is added, __ASSUME_SYSVIPC_BROKEN_MODE_T, which the required ABIs define. 4. For the ABIs that define __ASSUME_SYSVIPC_BROKEN_MODE_T, it also require compat symbols that do not adjust the mode field.

* alpha: force old OSF1 syscalls for getegid, geteuid and getppid [BZ #24986]Aurelien Jarno2019-09-143-0/+78
| | | | | | | | | | | | | | | | | | | | | | | | | | | | On alpha, Linux kernel 5.1 added the standard getegid, geteuid and getppid syscalls (commit ecf7e0a4ad15287). Up to now alpha was using the corresponding OSF1 syscalls through: - sysdeps/unix/alpha/getegid.S - sysdeps/unix/alpha/geteuid.S - sysdeps/unix/alpha/getppid.S When building against kernel headers >= 5.1, the glibc now use the new syscalls through sysdeps/unix/sysv/linux/syscalls.list. When it is then used with an older kernel, the corresponding 3 functions fail. A quick fix is to move the OSF1 wrappers under the sysdeps/unix/sysv/linux/alpha directory so they override the standard linux ones. A better fix would be to try the new syscalls and fallback to the old OSF1 in case the new ones fail. This can be implemented in a later commit.

* 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/.

* Refactor sigcontextinfo.hAdhemerval Zanella2019-08-232-102/+196

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/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.)
