* Replace {u}int_fast{16|32} with {u}int32_tNoah Goldstein2022-04-133-5/+5
| | | | | | | | | On 32-bit machines this has no affect. On 64-bit machines {u}int_fast{16|32} are set as {u}int64_t which is often not ideal. Particularly x86_64 this change both saves code size and may save instruction cost. Full xcheck passes on x86_64.

* gconv: Do not emit spurious NUL character in ISO-2022-JP-3 (bug 28524)Nikita Popov2021-11-043-9/+84
| | | | | | | | | | | | | | | | | | | | | | | | | | | Bugfix 27256 has introduced another issue: In conversion from ISO-2022-JP-3 encoding, it is possible to force iconv to emit extra NUL character on internal state reset. To do this, it is sufficient to feed iconv with escape sequence which switches active character set. The simplified check 'data->__statep->__count != ASCII_set' introduced by the aforementioned bugfix picks that case and behaves as if '\0' character has been queued thus emitting it. To eliminate this issue, these steps are taken: * Restore original condition '(data->__statep->__count & ~7) != ASCII_set'. It is necessary since bits 0-2 may contain number of buffered input characters. * Check that queued character is not NUL. Similar step is taken for main conversion loop. Bundled test case follows following logic: * Try to convert ISO-2022-JP-3 escape sequence switching active character set * Reset internal state by providing NULL as input buffer * Ensure that nothing has been converted.

* Remove "Contributed by" linesSiddhesh Poyarekar2021-09-03343-360/+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>
* Move malloc hooks into a compat DSOSiddhesh Poyarekar2021-07-221-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | Remove all malloc hook uses from core malloc functions and move it into a new library libc_malloc_debug.so. With this, the hooks now no longer have any effect on the core library. libc_malloc_debug.so is a malloc interposer that needs to be preloaded to get hooks functionality back so that the debugging features that depend on the hooks, i.e. malloc-check, mcheck and mtrace work again. Without the preloaded DSO these debugging features will be nops. These features will be ported away from hooks in subsequent patches. Similarly, legacy applications that need hooks functionality need to preload libc_malloc_debug.so. The symbols exported by libc_malloc_debug.so are maintained at exactly the same version as libc.so. Finally, static binaries will no longer be able to use malloc debugging features since they cannot preload the debugging DSO.

* gconv: Fix assertion failure in ISO-2022-JP-3 module (bug 27256)Florian Weimer2021-01-273-20/+178
| | | | | | | | | | | | | | | | | | The conversion loop to the internal encoding does not follow the interface contract that __GCONV_FULL_OUTPUT is only returned after the internal wchar_t buffer has been filled completely. This is enforced by the first of the two asserts in iconv/skeleton.c: /* We must run out of output buffer space in this rerun. */ assert (outbuf == outerr); assert (nstatus == __GCONV_FULL_OUTPUT); This commit solves this issue by queuing a second wide character which cannot be written immediately in the state variable, like other converters already do (e.g., BIG5-HKSCS or TSCII).

* iconv: Accept redundant shift sequences in IBM1364 [BZ #26224]Arjun Shankar2020-11-041-12/+2
| | | | | | | | | | | | | | | The IBM1364, IBM1371, IBM1388, IBM1390 and IBM1399 character sets share converter logic (iconvdata/ibm1364.c) which would reject redundant shift sequences when processing input in these character sets. This led to a hang in the iconv program (CVE-2020-27618). This commit adjusts the converter to ignore redundant shift sequences and adds test cases for iconv_prog hangs that would be triggered upon their rejection. This brings the implementation in line with other converters that also ignore redundant shift sequences (e.g. IBM930 etc., fixed in commit 692de4b3960d).

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!

* Increase some test timeouts.Joseph Myers2017-01-051-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | This patch increases timeouts on some tests I've observed timing out. elf/tst-tls13 and iconvdata/tst-loading both dynamically load many objects and so are slow when testing over NFS. They had timeouts set from before the default changed from 2 to 20 seconds; this patch removes those old settings, so effectively increasing the timeout to 20 seconds (from 3 and 10 seconds respectively). malloc/tst-malloc-thread-fail.c and malloc/tst-mallocfork2.c are slow on slow systems and so I set a fairly arbitrary 100 second timeout, which seems to suffice on the system where I saw them timing out. nss/tst-cancel-getpwuid_r.c and nss/tst-nss-getpwent.c are slow on systems with a large passwd file; I set timeouts that empirically worked for me. (It seems tst-cancel-getpwuid_r.c is hitting the 100000 getpwuid_r call limit in my testing, with each call taking a bit over 0.007 seconds, so 700 seconds for the test.) * elf/tst-tls13.c (TIMEOUT): Remove. * iconvdata/tst-loading.c (TIMEOUT): Likewise. * malloc/tst-malloc-thread-fail.c (TIMEOUT): Increase to 100. * malloc/tst-mallocfork2.c (TIMEOUT): Define to 100. * nss/tst-cancel-getpwuid_r.c (TIMEOUT): Define to 900. * nss/tst-nss-getpwent.c (TIMEOUT): Define to 300.

| | | | | | | | | | This commit adds a new DIAG_IGNORE_Os_NEEDS_COMMENT which is only enabled when compiling with -Os. This allows developers working on -Os enabled builds to mark false-positive warnings without impacting the warnings emitted at -O2. Then using the new DIAG_IGNORE_Os_NEEDS_COMMENT we fix 6 warnings generated with GCC 5 to get -Os builds working again.

* Fix UTF-16 surrogate handling. [BZ #19727]Stefan Liebler2016-05-254-2/+279
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | According to the latest Unicode standard, a conversion from/to UTF-xx has to report an error if the character value is in range of an utf16 surrogate (0xd800..0xdfff). See https://sourceware.org/ml/libc-help/2015-12/msg00015.html. Thus this patch fixes this behaviour for converting from utf32 to internal and from internal to utf8. Furthermore the conversion from utf16 to internal does not report an error if the input-stream consists of two low-surrogate values. If an uint16_t value is in the range of 0xd800 .. 0xdfff, the next uint16_t value is checked, if it is in the range of a low surrogate (0xdc00 .. 0xdfff). Afterwards these two uint16_t values are interpreted as a high- and low-surrogates pair. But there is no test if the first uint16_t value is really in the range of a high-surrogate (0xd800 .. 0xdbff). If there would be two uint16_t values in the range of a low surrogate, then they will be treated as a valid high- and low-surrogates pair. This patch adds this test. This patch also adds a new testcase, which checks UTF conversions with input values in range of UTF16 surrogates. The test converts from UTF-xx to INTERNAL, INTERNAL to UTF-xx and directly between UTF-xx to UTF-yy. The latter conversion is needed because s390 has iconv-modules, which converts from/to UTF in one step. The new testcase was tested on a s390, power and intel machine. ChangeLog: [BZ #19727] * iconvdata/utf-16.c (BODY): Report an error if first word is not a valid high surrogate. * iconvdata/utf-32.c (BODY): Report an error if the value is in range of an utf16 surrogate. * iconv/gconv_simple.c (BODY): Likewise. * iconvdata/bug-iconv12.c: New file. * iconvdata/Makefile (tests): Add bug-iconv12. rename test
* S390: Get rid of make warning: overriding recipe for target gconv-modules.Stefan Liebler2016-05-251-4/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch introduces a way to provide an architecture dependent gconv-modules file. Before this patch, the gconv-modules file was normally installed from src-dir/iconvdata/gconv-modules. The S390 Makefile had overridden the installation recipe (with a make warning) in order to install the gconv-module-s390 file from build-dir. The iconvdata/Makefile provides another recipe, which copies the gconv-modules file from src to build dir, which are used by the testcases. Thus the testcases does not use the currently build s390-modules. This patch uses build-dir/iconvdata/gconv-modules for installation, which is generated by concatenating src-dir/iconvdata/gconv-modules and the architecture specific one. The latter one can be specified by setting the variable sysdeps-gconv-modules in sysdeps/.../Makefile. The architecture specific gconv-modules file is emitted before the common one because these modules aren't used in all possible conversions. E.g. the converting from INTERNAL to UTF-16 used the common UTF-16.so module instead of UTF16_UTF32_Z9.so. This way, the s390-Makefile does not need to override the recipe for gconv-modules and no warning is emitted anymore. Since we no longer support empty objpfx the conditional test in iconvdata/Makefile is removed. ChangeLog: * iconvdata/Makefile ($(inst_gconvdir)/gconv-modules): Install file from $(objpfx)gconv-modules. ($(objpfx)gconv-modules): Concatenate architecture specific file in variable sysdeps-gconv-modules and gconv-modules in src dir. * sysdeps/s390/gconv-modules: New file. * sysdeps/s390/s390-64/Makefile: ($(inst_gconvdir)/gconv-modules): Deleted.
