* Fix stringop-overflow warning in bug-regex19.c.Stefan Liebler2021-05-181-0/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Starting with commit 26492c0a14966c32c43cd6ca1d0dca5e62c6cfef "Annotate additional APIs with GCC attribute access.", gcc emits this warning on s390x: In function 'do_one_test', inlined from 'do_mb_tests' at bug-regex19.c:385:11: bug-regex19.c:271:9: error: 're_search' specified size 18446744073709551615 exceeds maximum object size 9223372036854775807 [-Werror=stringop-overflow=] 271 | res = re_search (&regbuf, test->string, strlen (test->string), | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 272 | test->start, strlen (test->string) - test->start, NULL); | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ In file included from ../include/regex.h:2, from bug-regex19.c:22: bug-regex19.c: In function 'do_mb_tests': ../posix/regex.h:554:17: note: in a call to function 're_search' declared with attribute 'read_only (2, 3)' 554 | extern regoff_t re_search (struct re_pattern_buffer *__buffer, | ^~~~~~~~~ ... The function do_one_test is inlined into do_mb_tests on s390x (at least with gcc 10). If do_one_test is marked with __attribute__ ((noinline)), there are no warnings on s390x. If do_one_test is marked with __attribute__ ((always_inline)), there are the same warnings on x86_64. test->string points to a variable length array on stack of do_mb_tests and the content is generated based on the passed test struct. According to Martin Sebor, this is a false positive caused by the same bug as the one in nss/makedb.c. It's fixed in GCC 11 and will also be available in the next GCC 10.4 release.

| | | | | | | | | | | | | | | | I used these shell commands: ../glibc/scripts/update-copyrights $PWD/../gnulib/build-aux/update-copyright (cd ../glibc && git commit -am"[this commit message]") and then ignored the output, which consisted lines saying "FOO: warning: copyright statement not found" for each of 6694 files FOO. I then removed trailing white space from benchtests/bench-pthread-locks.c and iconvdata/tst-iconv-big5-hkscs-to-2ucs4.c, to work around this diagnostic from Savannah: remote: *** pre-commit check failed ... remote: *** error: lines with trailing whitespace found remote: error: hook declined to update refs/heads/master

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Also, change sources.redhat.com to sourceware.org. This patch was automatically generated by running the following shell script, which uses GNU sed, and which avoids modifying files imported from upstream: sed -ri ' s,(http|ftp)(://(.*\.)?(gnu|fsf|sourceware)\.org($|[^.]|\.[^a-z])),https\2,g s,(http|ftp)(://(.*\.)?)sources\.redhat\.com($|[^.]|\.[^a-z]),https\2sourceware.org\4,g ' \ $(find $(git ls-files) -prune -type f \ ! -name '*.po' \ ! -name 'ChangeLog*' \ ! -path COPYING ! -path COPYING.LIB \ ! -path manual/fdl-1.3.texi ! -path manual/lgpl-2.1.texi \ ! -path manual/texinfo.tex ! -path scripts/config.guess \ ! -path scripts/config.sub ! -path scripts/install-sh \ ! -path scripts/mkinstalldirs ! -path scripts/move-if-change \ ! -path INSTALL ! -path locale/programs/charmap-kw.h \ ! -path po/libc.pot ! -path sysdeps/gnu/errlist.c \ !
