| | | | | | | Commit 91927b7c76 ("Rewrite iconv option parsing [BZ #19519]") changed the iconv program to call __gconv_open directly instead of the iconv_open wrapper, but the former does not set errno. Update the caller to interpret the return codes like iconv_open does.

* Use O_CLOEXEC in more places (BZ #15722)Sergey Bugaev2023-04-221-1/+1
| | | | | | | | | | | | | When opening a temporary file without O_CLOEXEC we risk leaking the file descriptor if another thread calls (fork and then) exec while we have the fd open. Fix this by consistently passing O_CLOEXEC everywhere where we open a file for internal use (and not to return it to the user, in which case the API defines whether or not the close-on-exec flag shall be set on the returned fd).

* Move libc_freeres_ptrs and libc_subfreeres to hidden/weak functionsAdhemerval Zanella Netto2023-03-274-7/+10
| | | | | | | | | | | | | | | | | | | | They are both used by __libc_freeres to free all library malloc allocated resources to help tooling like mtrace or valgrind with memory leak tracking. The current scheme uses assembly markers and linker script entries to consolidate the free routine function pointers in the RELRO segment and to be freed buffers in BSS. This patch changes it to use specific free functions for libc_freeres_ptrs buffers and call the function pointer array directly with call_function_static_weak. It allows the removal of both the internal macros and the linker script sections. Checked on x86_64-linux-gnu, i686-linux-gnu, and aarch64-linux-gnu. Reviewed-by: Carlos O'Donell <carlos@redhat.com>

* Use PTR_MANGLE and PTR_DEMANGLE unconditionally in C sourcesFlorian Weimer2022-10-186-28/+0
| | | | | | | | | | | | | | | | | In the future, this will result in a compilation failure if the macros are unexpectedly undefined (due to header inclusion ordering or header inclusion missing altogether). Assembler sources are more difficult to convert. In many cases, they are hand-optimized for the mangling and no-mangling variants, which is why they are not converted. sysdeps/s390/s390-32/__longjmp.c and sysdeps/s390/s390-64/__longjmp.c are special: These are C sources, but most of the implementation is in assembler, so the PTR_DEMANGLE macro has to be undefined in some cases, to match the assembler style.

* Introduce <pointer_guard.h>, extracted from <sysdep.h>Florian Weimer2022-10-186-4/+6
| | | | | | | | | | | | | | This allows us to define a generic no-op version of PTR_MANGLE and PTR_DEMANGLE. In the future, we can use PTR_MANGLE and PTR_DEMANGLE unconditionally in C sources, avoiding an unintended loss of hardening due to missing include files or unlucky header inclusion ordering. In i386 and x86_64, we can avoid a <tls.h> dependency in the C code by using the computed constant from <tcb-offsets.h>. <sysdep.h> no longer includes these definitions, so there is no cyclic dependency anymore when computing the <tcb-offsets.h> constants.

Note that the SINGLE function is only used to implement the mb*towc*() or wc*tomb*() functions. Those functions use inptr and inend pointing to a variable on stack, compute the inend pointer or explicitly check the arguments which always leads to inptr < inend.

* Add generic C.UTF-8 locale (Bug 17318)Carlos O'Donell2021-09-062-3/+106
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We add a new C.UTF-8 locale. This locale is not builtin to glibc, but is provided as a distinct locale. The locale provides full support for UTF-8 and this includes full code point sorting via STRCMP-based collation (strcmp or wcscmp). The collation uses a new keyword 'codepoint_collation' which drops all collation rules and generates an empty zero rules collation to enable STRCMP usage in collation. This ensures that we get full code point sorting for C.UTF-8 with a minimal 1406 bytes of overhead (LC_COLLATE structure information and ASCII collating tables). The new locale is added to SUPPORTED. Minimal test data for specific code points (minus those not supported by collate-test) is provided in C.UTF-8.in, and this verifies code point sorting is working reasonably across the range. The locale was tested manually with the full set of code points without failure. The locale is harmonized with locales already shipping in various downstream distributions. A new tst-iconv9 test is added which verifies the C.UTF-8 locale is generally usable. Testing for fnmatch, regexec, and recomp is provided by extending bug-regex1, bugregex19, bug-regex4, bug-regex6, transbug, tst-fnmatch, tst-regcomp-truncated, and tst-regex to use C.UTF-8.

* Remove "Contributed by" linesSiddhesh Poyarekar2021-09-0329-29/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | We stopped adding "Contributed by" or similar lines in sources in 2012 in favour of git logs and keeping the Contributors section of the glibc manual up to date. Removing these lines makes the license header a bit more consistent across files and also removes the possibility of error in attribution when license blocks or files are copied across since the contributed-by lines don't actually reflect reality in those cases. Move all "Contributed by" and similar lines (Written by, Test by, etc.) into a new file CONTRIBUTED-BY to retain record of these contributions. These contributors are also mentioned in manual/contrib.texi, so we just maintain this additional record as a courtesy to the earlier developers. The following scripts were used to filter a list of files to edit in place and to clean up the CONTRIBUTED-BY file respectively. These were not added to the glibc sources because they're not expected to be of any use in future given that this is a one time task: https://gist.github.com/siddhesh/b5ecac94eabfd72ed2916d6d8157e7dc https://gist.github.com/siddhesh/15ea1f5e435ace9774f485030695ee02 Reviewed-by: Carlos O'Donell <carlos@redhat.com>
* Fix iconv build with GCC mainlineJoseph Myers2021-08-231-0/+6
| | | | | | | | | | | | | | | Current GCC mainline produces -Wstringop-overflow errors building some iconv converters, as discussed at <https://gcc.gnu.org/pipermail/gcc/2021-July/236943.html>. Add an __builtin_unreachable call as suggested so that GCC can see the case that would involve a buffer overflow is unreachable; because the unreachability depends on valid conversion state being passed into the function from previous conversion steps, it's not something the compiler can reasonably deduce on its own. Tested with build-many-glibcs.py that, together with <https://sourceware.org/pipermail/libc-alpha/2021-August/130244.html>, it restores the glibc build for powerpc-linux-gnu.

| | | | | | | | | | | | | | Previously, in UCS4 conversion routines we limit the number of characters we examine to the minimum of the number of characters in the input and the number of characters in the output. This is not the correct behavior when __GCONV_IGNORE_ERRORS is set, as we do not consume an output character when we skip a code unit. Instead, track the input and output pointers and terminate the loop when either reaches its limit. This resolves assertion failures when resetting the input buffer in a step of iconv, which assumes that the input will be fully consumed given sufficient output space.
