2018-07-05Compile debug/stack_chk_fail_local.c with stack protectorFlorian Weimer
The resulting object file is statically linked into applications, so it is desirable to have (formal) stack protector coverage there.
2018-06-01libio: Avoid _allocate_buffer, _free_buffer function pointers [BZ #23236]Florian Weimer
These unmangled function pointers reside on the heap and could be targeted by exploit writers, effectively bypassing libio vtable validation. Instead, we ignore these pointers and always call malloc or free. In theory, this is a backwards-incompatible change, but using the global heap instead of the user-supplied callback functions should have little application impact. (The old libstdc++ implementation exposed this functionality via a public, undocumented constructor in its strstreambuf class.)
2018-03-21Use x86_64 backtrace as generic version.Joseph Myers
No glibc configuration uses the present debug/backtrace.c, whereas several #include the x86_64 version. The x86_64 version is effectively a generic one (using _Unwind_Backtrace from libgcc, which works much more reliably than the built-in functions used by debug/backtrace.c). This patch moves it to debug/backtrace.c and removes all the #includes of the x86_64 version from other architectures which are no longer required. I do not know whether all the other architecture-specific backtrace implementations that are based on _Unwind_Backtrace are required, or whether, where their differences from the generic version do something useful, suitable hooks could be added to the generic version to reduce the duplication involved. Tested with build-many-glibcs.py that installed stripped shared libraries are unchanged by this patch. * sysdeps/x86_64/backtrace.c: Move to .... * debug/backtrace.c: ... here. * sysdeps/aarch64/backtrace.c: Remove file. * sysdeps/alpha/backtrace.c: Likewise. * sysdeps/hppa/backtrace.c: Likewise. * sysdeps/ia64/backtrace.c: Likewise. * sysdeps/mips/backtrace.c: Likewise. * sysdeps/nios2/backtrace.c: Likewise. * sysdeps/riscv/backtrace.c: Likewise. * sysdeps/sh/backtrace.c: Likewise. * sysdeps/tile/backtrace.c: Likewise.
2018-02-21Remove _IO_file_flags define.Zack Weinberg
This entirely mechanical (except for some indentation fixups) patch replaces all uses of _IO_file_flags with _flags and removes the #define. Installed stripped libraries and executables are unchanged by this patch. * libio/libio.h (_IO_file_flags): Remove macro. All uses changed to _flags.
2018-02-21Remove legacy configuration knobs from libio.Zack Weinberg
This patch eliminates the "compatibility defines" _IO_UNIFIED_JUMPTABLES (always defined to 1, used in a number of #ifs which are therefore always false), _STDIO_USES_IOSTREAM (unused), __HAVE_COLUMN (unused), _IO_BE (replaced with __glibc_unlikely), and yet another redundant definition of EOF. Installed stripped libraries are unchanged by this patch. * libio/libio.h (_IO_UNIFIED_JUMPTABLES, _STDIO_USES_IOSTREAM) (__HAVE_COLUMN, _IO_BE): Don't define. (_IO_peekc_unlocked, _IO_getwc_unlocked, _IO_putwc_unlocked) (_IO_fwide_maybe_incompatible): Use __glibc_unlikely. * libio/libioP.h (EOF): Don't define. * libio/iofdopen.c, libio/iofopen.c, libio/iopopen.c * libio/iovdprintf.c, libio/oldiofdopen.c, libio/oldiofopen.c * libio/oldiopopen.c, debug/vdprintf_chk.c: Remove #if block testing _IO_UNIFIED_JUMPTABLES.
2018-02-21Mechanically remove _IO_ name aliases for types and constants.Zack Weinberg
This patch mechanically removes all remaining uses, and the definitions, of the following libio name aliases: name replaced with ---- ------------- _IO_FILE FILE _IO_fpos_t __fpos_t _IO_fpos64_t __fpos64_t _IO_size_t size_t _IO_ssize_t ssize_t or __ssize_t _IO_off_t off_t _IO_off64_t off64_t _IO_pid_t pid_t _IO_uid_t uid_t _IO_wint_t wint_t _IO_va_list va_list or __gnuc_va_list _IO_BUFSIZ BUFSIZ _IO_cookie_io_functions_t cookie_io_functions_t __io_read_fn cookie_read_function_t __io_write_fn cookie_write_function_t __io_seek_fn cookie_seek_function_t __io_close_fn cookie_close_function_t I used __fpos_t and __fpos64_t instead of fpos_t and fpos64_t because the definitions of fpos_t and fpos64_t depend on the largefile mode. I used __ssize_t and __gnuc_va_list in a handful of headers where namespace cleanliness might be relevant even though they're internal-use-only. In all other cases, I used the public-namespace name. There are a tiny handful of places where I left a use of 'struct _IO_FILE' alone, because it was being used together with 'struct _IO_FILE_plus' or 'struct _IO_FILE_complete' in the same arithmetic expression. Because this patch was almost entirely done with search and replace, I may have introduced indentation botches. I did proofread the diff, but I may have missed something. The ChangeLog below calls out all of the places where this was not a pure search-and-replace change. Installed stripped libraries and executables are unchanged by this patch, except that some assertions in vfscanf.c change line numbers. * libio/libio.h (_IO_FILE): Delete; all uses changed to FILE.

2017-11-30x86: Make a space in jmpbuf for shadow stack pointerH.J. Lu
To support Shadow Stack (SHSTK) in Intel Control-flow Enforcement Technology (CET) in setjmp/longjmp, we need to save shadow stack pointer in jmp_buf. The __saved_mask field in jmp_buf has type of __sigset_t. On Linux, __sigset_t is defined as #define _SIGSET_NWORDS (1024 / (8 * sizeof (unsigned long int))) typedef struct { unsigned long int __val[_SIGSET_NWORDS]; } __sigset_t; which is much bigger than expected by the __sigprocmask system call, which has typedef struct { unsigned long sig[_NSIG_WORDS]; } sigset_t; For Linux/x86, we can shrink __sigset_t used by __saved_mask in jmp_buf to add paddings for shadow stack pointer. As long as the new __sigset_t is not smaller than sigset_t expected by the __sigprocmask system call, it should work correctly. This patch adds an internal header file, <setjmpP.h>, to define __jmp_buf_sigset_t for __saved_mask in jmp_buf for Linux/x86 with a space to store shadow stack pointer. It verifies __jmp_buf_sigset_t has the suitable size for the __sigprocmask system call. A run-time test, tst-saved_mask-1.c, is added to verify that size of __jmp_buf_sigset_t is sufficient. If its size is too small, the test fails with rt_sigprocmask(SIG_SETMASK, strace: umoven: short read (4 < 8) @0x7fa8aa28effc 0x7fa8aa28effc, NULL, 8) = -1 EFAULT (Bad address) rt_sigprocmask(SIG_SETMASK, strace: umoven: short read (4 < 8) @0x7fa8aa28effc 0x7fa8aa28effc, NULL, 8) = -1 EFAULT (Bad address) rt_sigprocmask(SIG_SETMASK, NULL, 0x7fa8aa28effc, 8) = -1 EFAULT (Bad address) exit_group(1) = ?

2017-09-05Fix pcprofiledump cross-endian condition (bug 22086).Joseph Myers
debug/pcprofiledump.c contains code that tries to handle other-endian data. This uses a condition "(word & 0xfffffff0) == bswap_32 (0xdeb00000)". This condition is always false (the LHS always has the low four bits zero, the RHS doesn't); a correct comparison would use 0x0fffffff. This results in -Werror=tautological-compare build failures with the tile version of bits/byteswap.h and mainline GCC. https://sourceware.org/ml/libc-testresults/2017-q3/msg00400.html pcprofiledump.c: In function 'main': pcprofiledump.c:118:39: error: bitwise comparison always evaluates to false [-Werror=tautological-compare] int must_swap = (word & 0xfffffff0) == bswap_32 (0xdeb00000); ^~ This patch fixes the condition. Tested for x86_64, and with build-many-glibcs.py that it fixes the build for tilegx-linux-gnu. (Note that I have not tested the actual pcprofiledump functionality, native or cross endian, which lacks any testsuite coverage.)

2017-06-05Fix struct sigaltstack namespace (bug 21517).Joseph Myers
glibc defines the stack_t type with the tag struct sigaltstack. This is not permitted by POSIX; sigaltstack is only reserved with file scope in the namespace of ordinary identifiers, not the tag namespace, and in the case where stack_t is obtained from ucontext.h rather than signal.h, it's not reserved with file scope at all. This patch removes the tag accordingly and updates uses in glibc of struct sigaltstack. This is similar to the removal of the "struct siginfo" tag a few years ago: C++ name mangling changes are an unavoidable consequence. A NEWS item is added to note the changed mangling. There is inevitably some risk of breaking builds of anything that relies on the struct sigaltstack name (though the first few hits I looked at from codesearch.debian.net generally seemed to involve code that could use the stack_t name conditionally, so depending on how they determine the conditionals they may work with glibc not defining the struct tag anyway). Tested for x86_64 and x86, and with build-many-glibcs.py.

2017-03-01Narrowing the visibility of libc-internal.h even further.Zack Weinberg
posix/wordexp-test.c used libc-internal.h for PTR_ALIGN_DOWN; similar to what was done with libc-diag.h, I have split the definitions of cast_to_integer, ALIGN_UP, ALIGN_DOWN, PTR_ALIGN_UP, and PTR_ALIGN_DOWN to a new header, libc-pointer-arith.h. It then occurred to me that the remaining declarations in libc-internal.h are mostly to do with early initialization, and probably most of the files including it, even in the core code, don't need it anymore. Indeed, only 19 files actually need what remains of libc-internal.h. 23 others need libc-diag.h instead, and 12 need libc-pointer-arith.h instead. No file needs more than one of them, and 16 don't need any of them! So, with this patch, libc-internal.h stops including libc-diag.h as well as losing the pointer arithmetic macros, and all including files are adjusted. * include/libc-pointer-arith.h: New file. Define cast_to_integer, ALIGN_UP, ALIGN_DOWN, PTR_ALIGN_UP, and PTR_ALIGN_DOWN here. * include/libc-internal.h: Definitions of above macros moved from here.

2017-02-25Clean up conditionals for declaration of gets.Zack Weinberg
gets has the dubious honor of being the only C89 library feature that has been completely removed from the current C and C++ standards. glibc follows suit by not declaring it in _GNU_SOURCE mode either, but it remains present in older compatibility modes. Internally, two test cases need to see stdio.h make the declaration, but all our internal code is of course compiled under _GNU_SOURCE. This is currently kludged by duplicating the gets declaration, fortify wrapper and all, in include/stdio.h. Also, the conditional in the public headers for deciding when to declare gets is complicated and repeated in two places. This patch adds a new macro to features.h that encapsulates the complicated rule for when to declare gets. stdio.h and bits/stdio2.h then simply test __GLIBC_USE (DEPRECATED_GETS), and instead of having a duplicate gets declaration in include/stdio.h, debug/tst-chk1.c and stdio-common/tst-gets.c can force gets to be declared. * include/features.h (__GLIBC_USE_DEPRECATED_GETS): New macro. * libio/stdio.h, libio/bits/stdio2.h: Condition gets on __GLIBC_USE (DEPRECATED_GETS).

2016-12-26PLT avoidance for __stack_chk_fail [BZ #7065]Nick Alcock
Add a hidden __stack_chk_fail_local alias to libc.so, and make sure that on targets which use __stack_chk_fail, this does not introduce a local PLT reference into libc.so.
2016-12-16New string function explicit_bzero (from OpenBSD).Zack Weinberg
explicit_bzero(s, n) is the same as memset(s, 0, n), except that the compiler is not allowed to delete a call to explicit_bzero even if the memory pointed to by 's' is dead after the call. Right now, this effect is achieved externally by having explicit_bzero be a function whose semantics are unknown to the compiler, and internally, with a no-op asm statement that clobbers memory. This does mean that small explicit_bzero operations cannot be expanded inline as small memset operations can, but on the other hand, small memset operations do get deleted by the compiler. Hopefully full compiler support for explicit_bzero will happen relatively soon. There are two new tests: test-explicit_bzero.c verifies the visible semantics in the same way as the existing test-bzero.c, and tst-xbzero-opt.c verifies the not-being-optimized-out property. The latter is conceptually based on a test written by Matthew Dempsky for the OpenBSD regression suite. The crypt() implementation has an immediate use for this new feature. We avoid having to add a GLIBC_PRIVATE alias for explicit_bzero by running all of libcrypt's calls through the fortified variant, __explicit_bzero_chk, which is in the impl namespace anyway. Currently I'm not aware of anything in libc proper that needs this, but the glue is all in place if it does become necessary.

2016-06-23libio: Implement vtable verification [BZ #20191]Florian Weimer
This commit puts all libio vtables in a dedicated, read-only ELF section, so that they are consecutive in memory. Before any indirect jump, the vtable pointer is checked against the section boundaries, and the process is terminated if the vtable pointer does not fall into the special ELF section. To enable backwards compatibility, a special flag variable (_IO_accept_foreign_vtables), protected by the pointer guard, avoids process termination if libio stream object constructor functions have been called earlier. Such constructor functions are called by the GCC 2.95 libstdc++ library, and this mechanism ensures compatibility with old binaries. Existing callers inside glibc of these functions are adjusted to call the original functions, not the wrappers which enable vtable compatiblity. The compatibility mechanism is used to enable passing FILE * objects across a static dlopen boundary, too.

2015-10-20Convert miscellaneous function definitions to prototype style.Joseph Myers
This patch converts various miscellaneous functions definitions in glibc, found with grep and not covered by my previous scripted conversions, from old-style K&R to prototype-style. These changes were made manually. This is not necessarily exhaustive as formatting variants may have prevented my grep from finding some such definitions. Regarding the changes to files from GMP, they may originally have been omitted when removing __STDC__ conditionals because of the files coming from another package, but (a) GMP no longer has __STDC__ conditionals there anyway and (b) we don't try to keep these files verbatim in sync with GMP (and there are licensing differences), so making the change to them in glibc seems reasonable.

2015-10-20Convert 113 more function definitions to prototype style (files with ↵Joseph Myers
assertions). This mostly automatically-generated patch converts 113 function definitions in glibc from old-style K&R to prototype-style. Following my other recent such patches, this one deals with the case of function definitions in files that either contain assertions or where grep suggested they might contain assertions - and thus where it isn't possible to use a simple object code comparison as a sanity check on the correctness of the patch, because line numbers are changed. A few such automatically-generated changes needed to be supplemented by manual changes for the result to compile. openat64 had a prototype declaration with "..." but an old-style definition in sysdeps/unix/sysv/linux/dl-openat64.c, and "..." needed adding to the generated prototype in the definition (I've filed <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=68024> for diagnosing such cases in GCC; the old state was undefined behavior not requiring a diagnostic, but one seems a good idea). In addition, as Florian has noted regparm attribute mismatches between declaration and definition are only diagnosed for prototype definitions, and five functions needed internal_function added to their definitions (in the case of __pthread_mutex_cond_lock, via the macro definition of __pthread_mutex_lock) to compile on i386. After this patch is in, remaining old-style definitions are probably most readily fixed manually before we can turn on -Wold-style-definition for all builds.

2015-10-16Convert 703 function definitions to prototype style.Joseph Myers
This automatically-generated patch converts 703 function definitions in glibc from old-style K&R to prototype-style. This conversion is deliberately simplistic, excluding any tricky cases as even a patch covering only simple cases is still very large. Currently excluded are: sysdeps files (to improve test coverage for the initial patch); files containing assertions (to avoid line number changes so that generated libraries can be compared); any cases where the generated function declaration would involve lines over 79 characters and so need to be wrapped; any cases with array parameters or other cases where parameter declarators don't end with the parameter name; any other cases that my script didn't parse. I didn't try to make the ChangeLog generation indicate when function definitions are conditional; it just lists the functions changed without regard to that. Tested for x86_64 and x86 (testsuite, and that installed stripped shared libraries are unchanged by the patch). * crypt/cert.c (good_bye): Convert to prototype-style function definition.

2015-10-15Remove -fexceptions configure test.Joseph Myers
There is a configure test for -fexceptions. This option was added in GCC 2.8, so the test is obsolete - and indeed plenty of code is using -fexceptions directly. This patch removes the configure test and makes all uses of $(exceptions) use -fexceptions directly.

2015-08-25Fix strcpy_chk and stpcpy_chk performance.Ondřej Bílka
Hi, as I wrote in previous patches a performance of checked strcpy and stpcpy is terrible as these don't use sse2 and are around four times slower that strcpy and stpcpy now. As this bug shows that these functions are not performance sensitive I decided just to improve generic implementation instead for easier maintainance. * debug/strcpy_chk.c: Improve performance. * debug/stpcpy_chk.c: Likewise. * sysdeps/x86_64/strcpy_chk.S: Remove. * sysdeps/x86_64/stpcpy_chk.S: Remove.

2015-08-14stpncpy: fix size checking [BZ #18975]Zack Weinberg
I think the last clause of the conditional, || __n <= __bos (__dest) may be backward. The code should call the runtime-checking function if __n is not constant, or if __n is known to be LARGER than the size of the destination.

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.

2014-12-10Use -Werror by default, add --disable-werror.Joseph Myers
As discussed starting at <https://sourceware.org/ml/libc-alpha/2014-11/msg00323.html>, this patch makes the glibc build use -Werror by default to avoid accidentally adding new warnings to the build. The configure option --disable-werror can be used to disable this. -Wno-error=undef is temporarily used because the build isn't clean regarding -Wundef warnings. The idea is that once the remaining -Wundef warnings have been cleaned up (in at least one configuration), -Wno-error=undef will be removed. I get a clean build and test on x86_64 (GCC 4.9 branch) with this patch. The expectation is that this may well break the build for some other configurations, and people seeing such breakage should make appropriate fixes to fix or suppress the warnings for their configurations. In some cases that may involve using pragmas as the right fix (I think that will be right for the -Wno-inline issue for MIPS I referred to in <https://sourceware.org/ml/libc-alpha/2012-11/msg00798.html>, for example), in some cases -Wno-error in sysdeps makefiles (__restore_rt in MIPS sigaction, for example), in some cases substantive fixes for the warnings. Note that if, with a view to listing all the warnings then fixing them all, you just look for "warning:" in output from building and testing with --disable-werror, you'll see lots of warnings from the linker about functions such as tmpnam. Those warnings can be ignored - only compiler warnings are relevant to -Werror, not linker warnings. * configure.ac (--disable-werror): New configure option. (enable_werror): New AC_SUBST. * configure: Regenerated. * config.make.in (enable-werror): New variable. * Makeconfig [$(enable-werror) = yes] (+gccwarn): Add -Werror -Wno-error=undef. (+gccwarn-c): Do not use -Werror=implicit-function-declaration. * manual/install.texi (Configuring and compiling): Document --disable-werror. * INSTALL: Regenerated. * debug/Makefile (CFLAGS-tst-chk1.c): Add -Wno-error.
