2017-01-01Update copyright dates not handled by scripts/update-copyrights.Joseph Myers1-1/+1
I've updated copyright dates in glibc for 2017. This is the patch for the changes not generated by scripts/update-copyrights and subsequent build / regeneration of generated files.

2016-12-31Add framework for tunablesSiddhesh Poyarekar2-2/+8
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.

2016-12-26Disable stack protector in early static initialization [BZ #7065]Nick Alcock1-0/+4
The startup code in csu/, and the brk and sbrk functions are needed very early in initialization of a statically-linked program, before the stack guard is initialized; TLS initialization also uses memcpy, which cannot overrun its own stack. Mark all of these as -fno-stack-protector. We also finally introduce @libc_cv_ssp@ and @no_stack_protector@, both substituted by the configury changes made earlier, to detect the case when -fno-stack-protector is supported by the compiler, and unconditionally pass it in when this is the case, whether or not --enable-stack-protector is passed to configure. (This means that it'll even work when the compiler's been hacked to pass -fstack-protector by default, unless the hackage is so broken that it does so in a way that is impossible to override.)
2016-12-26Initialize the stack guard earlier when linking statically [BZ #7065]Nick Alcock2-27/+19
The address of the stack canary is stored in a per-thread variable, which means that we must ensure that the TLS area is intialized before calling any -fstack-protector'ed functions. For dynamically linked applications, we ensure this (in a later patch) by disabling -fstack-protector for the whole dynamic linker, but for static applications, the AT_ENTRY address is called directly by the kernel, so we must deal with the problem differently. In static appliations, __libc_setup_tls performs the TCB setup and TLS initialization, so this commit arranges for it to be called early and unconditionally. The call (and the stack guard initialization) is before the DL_SYSDEP_OSCHECK hook, which if set will probably call functions which are stack-protected (it does on Linux and NaCL too). We also move apply_irel up, so that we can still safely call functions that require ifuncs while in __libc_setup_tls (though if stack-protection is enabled we still have to avoid calling functions that are not stack-protected at this stage).
2016-12-21Remove unused function _dl_tls_setupFlorian Weimer1-19/+0
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.
2016-12-21Move all tests out of the csu subdirectoryNick Alcock4-678/+3
Stack-protection on .o files in csu/ must be suppressed for the sake of library startup code. This also suppresses stack-protection in tests (which are also covered by CFLAGS-.o), though this is neither necessary nor desirable. So impose the rule that .o files in csu/ are necessarily C startup code, and move the few tests in there into misc/ instead.
2016-09-10Remove __libc_csu_irel declarationSiddhesh Poyarekar1-3/+0
21ad055803de5dd03606588753c46fbf8a5863b2 removed the function, but missed the declaration in libc-start. Removed and verified that the generated assembly is unchanged. * csu/libc-start.c (__libc_csu_irel): Remove declaration.
2016-08-03elf: Avoid using memalign for TLS allocations [BZ #17730]Florian Weimer1-1/+1
Instead of a flag which indicates the pointer can be freed, dtv_t now includes the pointer which should be freed. Due to padding, the size of dtv_t does not increase. To avoid using memalign, the new allocate_dtv_entry function allocates a sufficiently large buffer so that a sub-buffer can be found in it which starts with an aligned pointer. Both the aligned and original pointers are kept, the latter for calling free later.

Apart from the files updated last time (of which sotruss.ksh had moved to sotruss.sh during the year) this also updates nptl/version.c (missed from 2006 until October) and sysdeps/unix/sysv/linux/lddlibc4.c (missed since 2009). * NEWS: Update copyright dates. * catgets/gencat.c (print_version): Likewise. * csu/version.c (banner): Likewise. * debug/catchsegv.sh: Likewise. * debug/pcprofiledump.c (print_version): Likewise. * debug/xtrace.sh (do_version): Likewise. * elf/ldconfig.c (print_version): Likewise. * elf/ldd.bash.in: Likewise. * elf/pldd.c (print_version): Likewise. * elf/sotruss.sh: Likewise. * elf/sprof.c (print_version): Likewise. * iconv/iconv_prog.c (print_version): Likewise. * iconv/iconvconfig.c (print_version): Likewise. * locale/programs/locale.c (print_version): Likewise. * locale/programs/localedef.c (print_version): Likewise. * login/programs/pt_chown.c (print_version): Likewise. * malloc/memusage.sh (do_version): Likewise. * malloc/memusagestat.c (print_version): Likewise. * malloc/mtrace.pl: Likewise. * manual/libc.texinfo: Likewise. * nptl/version.c (banner): Likewise. * nscd/nscd.c (print_version): Likewise. * nss/getent.c (print_version): Likewise. * nss/makedb.c (print_version): Likewise. * posix/getconf.c (main): Likewise. * scripts/test-installation.pl: Likewise. * sysdeps/unix/sysv/linux/lddlibc4.c (main): Likewise.

2014-11-05Modify several tests to use test-skeleton.cArjun Shankar1-2/+5
This patch modifies several test cases to use test-skeleton.c. It was generated by a bash script written for this purpose and thus excludes several other tests which I deemed worth a visual inspection before making the change. I intend to follow up with individual patches to the tests skipped by the script. The script itself resides at http://git.io/WODAmg and should reproduce this very patch when run against master.

2014-09-16Remove bitrotten --enable-oldest-abi (bug 6652).Joseph Myers1-3/+0
This patch removes the --enable-oldest-abi configure option, which has long been bitrotten (as reported in bug 6652). The principle of removing this option was agreed in the thread starting at <https://sourceware.org/ml/libc-alpha/2013-07/msg00174.html>. Tested for x86_64 and x86 that the installed shared libraries other than libc.so are unchanged by this patch and that libc.so disassembly and symbol versions are unchanged (debug info changes because of changed line numbers in csu/version.c).

2014-02-26Consistently include Makeconfig after defining subdir.Joseph Myers1-4/+2
In <https://sourceware.org/ml/libc-alpha/2014-01/msg00196.html> I noted it was necessary to add includes of Makeconfig early in various subdirectory makefiles for the tests-special variable settings added by that patch to be conditional on configuration information. No-one commented on the general question there of whether Makeconfig should always be included immediately after the definition of subdir. This patch implements that early inclusion of Makeconfig in each directory (which is a lot easier than consistent placement of includes of Rules). Includes are added if needed, or moved up if already present. Subdirectory "all:" targets are removed, since Makeconfig provides one. There is potential for further cleanups I haven't done. Rules and Makerules have code such as ifneq "$(findstring env,$(origin headers))" "" headers := endif to override to empty any value of various variables that came from the environment. I think there is a case for Makeconfig setting all the subdirectory variables (other than subdir) to empty to ensure no outside value is going to take effect if a subdirectory fails to define a variable. (A list of such variables, possibly out of date and incomplete, is in manual/maint.texi.) Rules and Makerules would give errors if Makeconfig hadn't already been included, instead of including it themselves. The special code to override values coming from the environment would then be obsolete and could be removed. Tested x86_64, including that installed binaries are identical before and after the patch. * argp/Makefile: Include Makeconfig immediately after defining subdir. * assert/Makefile: Likewise. * benchtests/Makefile: Likewise. * catgets/Makefile: Likewise. * conform/Makefile: Likewise. * crypt/Makefile: Likewise. * csu/Makefile: Likewise.

2014-01-31[BZ #16046] Static dlopen correction fallout fixes.Maciej W. Rozycki1-15/+12
Fixes to address issues from BZ #15022 resolution, as follows: * TLS updates to csu/libc-tls.c -- we now have a proper main map, so there's no longer a need to create a separate fake one to keep TLS structures, * random updates to elf/dl-close.c -- LM_ID_BASE is now a valid name space ID for static executables as well, so assert that we don't unload the main map. Similarly dl_nns isn't supposed to be 0 for static executables anymore, * actual BZ #16046 fix to elf/dl-iteratephdr.c -- the dl_iterate_phdr special function for static executables isn't needed anymore, provided that l_phdr and l_phnum members of the main map have been properly initialized (done in _dl_non_dynamic_init in elf/dl-support.c now), * ld.so.cache loader update to elf/dl-load.c -- GL(dl_ns)[LM_ID_BASE]._ns_loaded is now always initialized in static executables so can become the fallback loader map to check for DF_1_NODEFLIB, provided that the l_flags_1 member of the main map has been properly initialized (done in elf/dl-support.c now); this also ensures previous semantics elsewhere in elf/dl-load.c, * matching updates to elf/dl-support.c -- to complement the two fixes above.

Long ago static startup did not parse the auxiliary vector and therefore could not get at any `AT_FPUCW' tag to check whether upon FPU context allocation the kernel would use a FPU control word setting different to that provided by the `__fpu_control' variable. Static startup therefore always initialized the FPU control word, forcing immediate FPU context allocation even for binaries that otherwise never used the FPU. As from GIT commit f8f900ecb9096ec47f5b7bb7626e29223c69061a static startup supports parsing the auxiliary vector, so now it can avoid explicit initialization of the FPU control word, just as can dynamic startup, in the usual case where the setting written to the FPU control word would be the same as the kernel uses. This defers FPU context allocation until the binary itself actually pokes at the FPU. Note that the `AT_FPUCW' tag is usually absent from the auxiliary vector in which case _FPU_DEFAULT is assumed to be the kernel default.

This avoids a linker bug triggering for MIPS SVR4 binaries: http://sourceware.org/bugzilla/show_bug.cgi?id=15365 and regardless serves as a documentation of intent.

2013-03-01Revert GLIBC_PTHREAD_DEFAULT_STACKSIZE changes.Carlos O'Donell2-3/+3
This reverts the change that allows the POSIX Thread default stack size to be changed by the environment variable GLIBC_PTHREAD_DEFAULT_STACKSIZE. It has been requested that more discussion happen before this change goes into 2.18.
