* Fix range check in do_tunable_update_valAlexey Makhalov2017-09-271-11/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current implementation of tunables does not set arena_max and arena_test values. Any value provided by glibc.malloc.arena_max and glibc.malloc.arena_test parameters is ignored. These tunables have minval value set to 1 (see elf/dl-tunables.list file) and undefined maxval value. In that case default value (which is 0. see scripts/gen-tunables.awk) is being used to set maxval. For instance, generated tunable_list[] entry for arena_max is: (gdb) p *cur $1 = {name = 0x7ffff7df6217 "glibc.malloc.arena_max", type = {type_code = TUNABLE_TYPE_SIZE_T, min = 1, max = 0}, val = {numval = 0, strval = 0x0}, initialized = false, security_level = TUNABLE_SECLEVEL_SXID_IGNORE, env_alias = 0x7ffff7df622e "MALLOC_ARENA_MAX"} As a result, any value of glibc.malloc.arena_max is ignored by TUNABLE_SET_VAL_IF_VALID_RANGE macro __type min = (__cur)->type.min; <- initialized to 1 __type max = (__cur)->type.max; <- initialized to 0! if (min == max) <- false { min = __default_min; max = __default_max; } if ((__type) (__val) >= min && (__type) (val) <= max) <- false { (__cur)->val.numval = val; (__cur)->initialized = true; } Assigning correct min/max values at a build time fixes a problem. Plus, a bit of optimization: Setting of default min/max values for the given type at a run time might be eliminated. * elf/dl-tunables.c (do_tunable_update_val): Range checking fix. * scripts/gen-tunables.awk: Set unspecified minval and/or maxval values to correct default value for given type.
* Skip PT_DYNAMIC segment with p_filesz == 0 [BZ #22101]H.J. Lu2017-09-263-3/+50
| | | | | | | | | | | | | | | | | | | | | | | | | | ELF objects generated with "objcopy --only-keep-debug" have Type Offset VirtAddr PhysAddr FileSiz MemSiz Flg Align DYNAMIC 0x0+e28 0x0+200e40 0x0+200e40 0x0+ 0x0+1a0 RW 0x8 with 0 file size. ld.so should skip such PT_DYNAMIC segments. Without a PT_DYNAMIC segment the loading of the shared object will fail, and therefore ldd on such objects will also fail instead of crashing. This provides better diagnostics for tooling that is attempting to inspect the invalid shared objects which may just contain debug information. [BZ #22101] * elf/Makefile (tests): Add tst-debug1.

* _dl_init: Remove internal_function attributeFlorian Weimer2017-08-141-1/+0
| | | | | The function is called from the i386 startup code, which needs minor adjustments due to the changed ABI.
* _dl_start: Remove internal_function attributeFlorian Weimer2017-08-141-1/+1
| | | | | The i386 startup code needs adjusting because it calls the function and the ABI has changed.
* _dl_fini: Remove internal_function attributeFlorian Weimer2017-08-141-1/+0
| | | | | | | | | | Assembler code passes the address of _dl_fini to __libc_start_main, whose function pointer argument lacks the attribute. This means that calls could use the wrong ABI. Fortunately, for zero-parameter void-returning functions, internal_function does not change ABI on i386 (the only architecture which uses internal_function), so this inconsistency was harmless (which is why it had not been noticed so far).
* ld.so: Remove internal_function attribute from various functionsFlorian Weimer2017-08-134-9/+0

* ld.so: Introduce struct dl_exceptionFlorian Weimer2017-08-109-218/+347
| | | | | | This commit separates allocating and raising exceptions. This simplifies catching and re-raising them because it is no longer necessary to make a temporary, on-stack copy of the exception message.
* i386: Add <startup.h> [BZ #21913]H.J. Lu2017-08-081-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On Linux/i386, there are 3 ways to make a system call: 1. call *%gs:SYSINFO_OFFSET. This requires TLS initialization. 2. call *_dl_sysinfo. This requires relocation of _dl_sysinfo. 3. int $0x80. This is slower than #2 and #3, but works everywhere. When an object file is compiled with PIC, #1 is prefered since it is faster than #3 and doesn't require relocation of _dl_sysinfo. For dynamic executables, ld.so initializes TLS. However, for static executables, before TLS is initialized by __libc_setup_tls, #3 should be used for system calls. This patch adds <startup.h> which defines _startup_fatal and defaults it to __libc_fatal. It replaces __libc_fatal with _startup_fatal in static executables where it is called before __libc_setup_tls is called. This header file is included in all files containing functions which are called before __libc_setup_tls is called. On Linux/i386, when PIE is enabled by default, _startup_fatal is turned into ABORT_INSTRUCTION and I386_USE_SYSENTER is defined to 0 so that "int $0x80" is used for system calls before __libc_setup_tls is called. Tested on i686 and x86-64. Without this patch, all statically-linked tests will fail on i686 when the compiler defaults to -fPIE. [BZ #21913] * csu/libc-tls.c: Include <startup.h> first.

* tunables: Use direct syscall for access (BZ#21744)Adhemerval Zanella2017-07-241-0/+2
| | | | | | | | | | | | | | | | | | | | | | | The function maybe_enable_malloc_check, which is called by __tunables_init, calls __access_noerrno. It isn't problem when symbol is is in ld.so, which has a special version of __access_noerrno without stack protector. But when glibc is built with stack protector, maybe_enable_malloc_check in libc.a can't call the regular version of __access_noerrno with stack protector. This patch changes how Linux defines the __access_noerrno to be an inline call instead and thus preventing defining different build rules for ld/static and shared. H.J.

* tunables: Add IFUNC selection and cache sizesH.J. Lu2017-06-201-0/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current IFUNC selection is based on microbenchmarks in glibc. It should give the best performance for most workloads. But other choices may have better performance for a particular workload or on the hardware which wasn't available at the selection was made. The environment variable, GLIBC_TUNABLES=glibc.tune.ifunc=-xxx,yyy,-zzz...., can be used to enable CPU/ARCH feature yyy, disable CPU/ARCH feature yyy and zzz, where the feature name is case-sensitive and has to match the ones in cpu-features.h. It can be used by glibc developers to override the IFUNC selection to tune for a new processor or improve performance for a particular workload. It isn't intended for normal end users. NOTE: the IFUNC selection may change over time. Please check all multiarch implementations when experimenting. Also, GLIBC_TUNABLES=glibc.tune.x86_non_temporal_threshold=NUMBER is provided to set threshold to use non temporal store to NUMBER, GLIBC_TUNABLES=glibc.tune.x86_data_cache_size=NUMBER to set data cache size, GLIBC_TUNABLES=glibc.tune.x86_shared_cache_size=NUMBER to set shared cache size. * elf/dl-tunables.list (tune): Add ifunc, x86_non_temporal_threshold, x86_data_cache_size and x86_shared_cache_size. * manual/tunables.texi: Document glibc.tune.ifunc, glibc.tune.x86_data_cache_size, glibc.tune.x86_shared_cache_size and glibc.tune.x86_non_temporal_threshold. * sysdeps/unix/sysv/linux/x86/dl-sysdep.c: New file. * sysdeps/x86/cpu-tunables.c: Likewise. * sysdeps/x86/cacheinfo.c (init_cacheinfo): Check and get data cache size, shared cache size and non temporal threshold from cpu_features. * sysdeps/x86/cpu-features.c [HAVE_TUNABLES] (TUNABLE_NAMESPACE): New.

This patch implements the ld.so changes necessary for this optimization. ld.so needs to check that an optimized plt call sequence is in fact calling a function implemented with localentry:0, end emit a fatal error otherwise.

* Make LD_HWCAP_MASK usable for static binariesSiddhesh Poyarekar2017-06-071-8/+7
| | | | | | | | | | | | | | | | | | The LD_HWCAP_MASK environment variable was ignored in static binaries, which is inconsistent with the behaviour of dynamically linked binaries. This seems to have been because of the inability of ld_hwcap_mask being read early enough to influence anything but now that it is in tunables, the mask is usable in static binaries as well. This feature is important for aarch64, which relies on HWCAP_CPUID being masked out to disable multiarch. A sanity test on x86_64 shows that there are no failures. Likewise for aarch64. * elf/dl-hwcaps.h [HAVE_TUNABLES]: Always read hwcap_mask. * sysdeps/sparc/sparc32/dl-machine.h [HAVE_TUNABLES]: Likewise. * sysdeps/x86/cpu-features.c (init_cpu_features): Always set up hwcap and hwcap_mask.

* tunables: Add LD_HWCAP_MASK to tunablesSiddhesh Poyarekar2017-06-071-0/+7
| | | | | | | | | | | | | | | | Add LD_HWCAP_MASK to tunables in preparation of it being removed from rtld.c. This allows us to read LD_HWCAP_MASK much earlier so that it can influence IFUNC resolution in aarch64. This patch does not actually do anything other than read the LD_HWCAP_MASK variable and add the tunables way to set the LD_HWCAP_MASK, i.e. via the glibc.tune.hwcap_mask tunable. In a follow-up patch, the _dl_hwcap_mask will be replaced with glibc.tune.hwcap_mask to complete the transition. * elf/dl-tunables.list: Add glibc.tune.hwcap_mask. * scripts/gen-tunables.awk: Include dl-procinfo.h. * manual/tunables.texi: Document glibc.tune.hwcap_mask.
* tunables: Clean up hooks to get and set tunablesSiddhesh Poyarekar2017-06-073-41/+72
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The TUNABLE_SET_VALUE and family of macros (and my later attempt to add a TUNABLE_GET) never quite went together very well because the overall interface was not clearly defined. This patch is an attempt to do just that. This patch consolidates the API to two simple sets of macros, TUNABLE_GET* and TUNABLE_SET*. If TUNABLE_NAMESPACE is defined, TUNABLE_GET takes just the tunable name, type and a (optionally NULL) callback function to get the value of the tunable. The callback function, if non-NULL, is called if the tunable was externally set (i.e. via GLIBC_TUNABLES or any future mechanism). For example: val = TUNABLE_GET (check, int32_t, check_callback) returns the value of the glibc.malloc.check tunable (assuming TUNABLE_NAMESPACE is set to malloc) as an int32_t into VAL after calling check_callback. Likewise, TUNABLE_SET can be used to set the value of the tunable, although this is currently possible only in the dynamic linker before it relocates itself. For example: TUNABLE_SET (check, int32_t, 2) will set glibc.malloc.check to 2. Of course, this is not possible since we set (or read) glibc.malloc.check long after it is relocated. To access or set a tunable outside of TUNABLE_NAMESPACE, use the TUNABLE_GET_FULL and TUNABLE_SET_FULL macros, which have the following prototype: TUNABLE_GET_FULL (glibc, tune, hwcap_mask, uint64_t, NULL) TUNABLE_SET_FULL (glibc, tune, hwcap_mask, uint64_t, 0xffff) In future the tunable list may get split into mutable and immutable tunables where mutable tunables can be modified by the library and userspace after relocation as well and TUNABLE_SET will be more useful than it currently is. However whenever we actually do that split, we will have to ensure that the mutable tunables are protected with locks. * elf/Versions (__tunable_set_val): Rename to __tunable_get_val. * elf/dl-tunables.c: Likewise. (do_tunable_update_val): New function. (__tunable_set_val): New function. (__tunable_get_val): Call CB only if the tunable was externally initialized. (tunables_strtoul): Replace strval with initialized. * elf/dl-tunables.h (strval): Replace with a bool initialized. (TUNABLE_ENUM_NAME, TUNABLE_ENUM_NAME1): Adjust names to prevent collision.

* Make __tunables_init hidden and avoid PLTH.J. Lu2017-05-252-0/+5
| | | | | | | | | | | | | Since __tunables_init is internal to ld.so, we should mark it hidden to avoid PLT. We should also avoid PLT when calling __tunable_set_val within ld.so. 2017-05-25 Siddhesh Poyarekar <siddhesh@sourceware.org> H.J. Lu <hongjiu.lu@intel.com> * elf/dl-tunables.c (__tunable_set_val): Make a hidden alias. * elf/dl-tunables.h (__tunables_init): Mark it hidden in rtld. (__tunable_set_val): Likewise.
* Reduce value of LD_HWCAP_MASK for tst-env-setuid test caseSiddhesh Poyarekar2017-05-191-1/+1
| | | | | | | | | | | | | | | It was discovered that the dynamic linker allocates a massive amount of memory that increases with the value of LD_HWCAP_MASK. Due to this, setting its value to 0xffffffff in the environment of tst-env-setuid would cause it to fail in some environments where overcommit was disabled or severely constrained because malloc would fail. Since this test is only concerned with the value of LD_HWCAP_MASK envvar being conserved (or not, for setxid binaries), lower its value to avoid spurious failures. The allocation bug is reported as #21502.
* tunables: Add support for tunables of uint64_t typeSiddhesh Poyarekar2017-05-172-54/+41
| | | | | | | | | | | | | | | | | | | | | | | | | Recognize the uint64_t type in addition to the current int32_t and size_t. This allows addition of tunables of uint64_t types. In addition to adding the uint64_t type, this patch also consolidates validation and reading of integer types in tunables. One notable change is that of overflow computation in tunables_strtoul. The function was lifted from __internal_strtoul, but it does not need the boundary condition check (i.e. result == ULONG_MAX) since it does not need to set errno. As a result the check can be simplified, which I have now done. * elf/dl-tunable-types.h (tunable_type_code_t): New type TUNABLE_TYPE_UINT_64. * elf/dl-tunables.c (tunables_strtoul): Return uint64_t. Simplify computation of overflow. (tunable_set_val_if_valid_range_signed, tunable_set_val_if_valid_range_unsigned): Remove and replace with this... (TUNABLE_SET_VAL_IF_VALID_RANGE): ... New macro. (tunable_initialize): Adjust. Add uint64_t support. (__tunable_set_val): Add uint64_t support. * README.tunables: Document it.
* Suppress internal declarations for most of the testsuite.Zack Weinberg2017-05-112-25/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a new build module called 'testsuite'. IS_IN (testsuite) implies _ISOMAC, as do IS_IN_build and __cplusplus (which means several ad-hoc tests for __cplusplus can go away). libc-symbols.h now suppresses almost all of *itself* when _ISOMAC is defined; in particular, _ISOMAC mode does not get config.h automatically anymore. There are still quite a few tests that need to see internal gunk of one variety or another. For them, we now have 'tests-internal' and 'test-internal-extras'; files in this category will still be compiled with MODULE_NAME=nonlib, and everything proceeds as it always has. The bulk of this patch is moving tests from 'tests' to 'tests-internal'. There is also 'tests-static-internal', which has the same effect on files in 'tests-static', and 'modules-names-tests', which has the *inverse* effect on files in 'modules-names' (it's inverted because most of the things in modules-names are *not* tests). For both of these, the file must appear in *both* the new variable and the old one. There is also now a special case for when libc-symbols.h is included without MODULE_NAME being defined at all. (This happens during the creation of libc-modules.h, and also when preprocessing Versions files.) When this happens, IS_IN is set to be always false and _ISOMAC is *not* defined, which was the status quo, but now it's explicit. The remaining changes to C source files in this patch seemed likely to cause problems in the absence of the main change. They should be relatively self-explanatory. In a few cases I duplicated a definition from an internal header rather than move the test to tests-internal; this was a judgement call each time and I'm happy to change those however reviewers feel is more appropriate. * Makerules: New subdir configuration variables 'tests-internal' and 'test-internal-extras'. Test files in these categories will still be compiled with MODULE_NAME=nonlib. Test files in the existing categories (tests, xtests, test-srcs, test-extras) are now compiled with MODULE_NAME=testsuite. New subdir configuration variable 'modules-names-tests'. Files which are in both 'modules-names' and 'modules-names-tests' will be compiled with MODULE_NAME=testsuite instead of MODULE_NAME=extramodules. (gen-as-const-headers): Move to tests-internal. (do-tests-clean, common-mostlyclean): Support tests-internal. * Makeconfig (built-modules): Add testsuite. * Makefile: Change libof-check-installed-headers-c and libof-check-installed-headers-cxx to 'testsuite'. * Rules: Likewise. Support tests-internal. * benchtests/strcoll-inputs/filelist#en_US.UTF-8: Remove extra-modules.mk. * config.h.in: Don't check for __OPTIMIZE__ or __FAST_MATH__ here. * include/libc-symbols.h: Move definitions of _GNU_SOURCE, PASTE_NAME, PASTE_NAME1, IN_MODULE, IS_IN, and IS_IN_LIB to the very top of the file and rationalize their order. If MODULE_NAME is not defined at all, define IS_IN to always be false, and don't define _ISOMAC. If any of IS_IN (testsuite), IS_IN_build, or __cplusplus are true, define _ISOMAC and suppress everything else in this file, starting with the inclusion of config.h. Do check for inappropriate definitions of __OPTIMIZE__ and __FAST_MATH__ here, but only if _ISOMAC is not defined. Correct some out-of-date commentary. * include/math.h: If _ISOMAC is defined, undefine NO_LONG_DOUBLE and _Mlong_double_ before including math.h. * include/string.h: If _ISOMAC is defined, don't expose _STRING_ARCH_unaligned.

| | | | | | | | | | | | | | | | | | | | | | cppflags-iterator.mk no longer has anything to do with CPPFLAGS; all it does is set libof-$(foo) for a list of files. extra-modules.mk does the same thing, but with a different input variable, and doesn't let the caller control the module.
