2014-04-14Support _r_debug for static binaries.Carlos O'Donell
We initialize _r_debug for static binaries to allows debug agents to treat static binaries a little more like dyanmic ones. This simplifies the work a debug agent has to do to access TLS in a static binary via libthread_db. Tested on x86_64. See: https://sourceware.org/ml/libc-alpha/2014-04/msg00183.html [BZ #16831] * csu/libc-start.c (LIBC_START_MAIN) [!SHARED]: Call _dl_debug_initialize.

2014-02-28Fix fallout from Joseph's untested Makeconfig change.Roland McGrath
2014-02-26Consistently include Makeconfig after defining subdir.Joseph Myers
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 (A list of such variables, possibly out of date and incomplete, is in manual/maint.texi.)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. Rozycki
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.

2013-09-23BZ #15754: CVE-2013-4788Carlos O'Donell
The pointer guard used for pointer mangling was not initialized for static applications resulting in the security feature being disabled. The pointer guard is now correctly initialized to a random value for static applications. Existing static applications need to be recompiled to take advantage of the fix. The test tst-ptrguard1-static and tst-ptrguard1 add regression coverage to ensure the pointer guards are sufficiently random and initialized to a default value.
2013-09-09Fix static-binary lazy FPU context allocationMaciej W. Rozycki
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.
