2018-01-04elf: Support dlvsym within libc.soFlorian Weimer
This commit adds a new _dl_open_hook entry for dlvsym and implements the function using the existing dl_lookup_symbol_x function supplied by the dynamic loader. A new hook variable, _dl_open_hook2, is introduced, which should make this change suitable for backporting: For old statically linked binaries, __libc_dlvsym will always return NULL.
2017-08-10ld.so: Introduce struct dl_exceptionFlorian Weimer
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.
2017-06-16Remove _dl_out_of_memory from elf/VersionsH.J. Lu
Since _dl_out_of_memory is static in elf/dl-error-skeleton.c: static const char _dl_out_of_memory[] = "out of memory"; remove _dl_out_of_memory from elf/Versions. * elf/Versions (ld): Remove _dl_out_of_memory.
2017-06-07tunables: Clean up hooks to get and set tunablesSiddhesh Poyarekar
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.

2016-12-31Add framework for tunablesSiddhesh Poyarekar
The tunables framework allows us to uniformly manage and expose global variables inside glibc as switches to users. tunables/README has instructions for glibc developers to add new tunables. Tunables support can be enabled by passing the --enable-tunables configure flag to the configure script. This patch only adds a framework and does not pose any limitations on how tunable values are read from the user. It also adds environment variables used in malloc behaviour tweaking to the tunables framework as a PoC of the compatibility interface. * manual/install.texi: Add --enable-tunables option. * INSTALL: Regenerate. * README.tunables: New file. * Makeconfig (CPPFLAGS): Define TOP_NAMESPACE.

2016-12-21Remove unused function _dl_tls_setupFlorian Weimer
Commit 7a5e3d9d633c828d84a9535f26b202a6179978e7 (elf: Assume TLS is initialized in _dl_map_object_from_fd) removed the last call of _dl_tls_setup, but did not remove the function itself.
2016-11-30ld.so: Remove __libc_memalignFlorian Weimer
It is no longer needed since commit 6c444ad6e953dbdf9c7be065308a0a777 (elf: Do not use memalign for TCB/TLS blocks allocation [BZ #17730]). Applications do not link against ld.so and will use the definition in libc.so, so there is no ABI impact.
2016-11-30Implement _dl_catch_error, _dl_signal_error in libc.so [BZ #16628]Florian Weimer
This change moves the main implementation of _dl_catch_error, _dl_signal_error to libc.so, where TLS variables can be used directly. This removes a writable function pointer from the rtld_global variable. For use during initial relocation, minimal implementations of these functions are provided in ld.so. These are eventually interposed by the libc.so implementations. This is implemented by compiling elf/dl-error-skeleton.c twice, via elf/dl-error.c and elf/dl-error-minimal.c. As a side effect of this change, the static version of dl-error.c no longer includes support for the _dl_signal_cerror/_dl_receive_error mechanism because it is only used in ld.so.
