This change continues the improvements to compile-time out of bounds
checking by decorating more APIs with either attribute access, or by
explicitly providing the array bound in APIs such as tmpnam() that
expect arrays of some minimum size as arguments. (The latter feature
is new in GCC 11.)
The only effects of the attribute and/or the array bound is to check
and diagnose calls to the functions that fail to provide a sufficient
number of elements, and the definitions of the functions that access
elements outside the specified bounds. (There is no interplay with
_FORTIFY_SOURCE here yet.)
Tested with GCC 7 through 11 on x86_64-linux.
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
On some platforms the inclusion of regex-internal.h in bug-regex33
testcase show a MAX redefinition if test-skeleton.c is include later.
This patch fixes by removing regex-internal.h inclusion and using
SBC_MAX value directly.
Checked on aarch64-linux-gnu.
* posix/bug-regex33.c: Fix build after regex sync.
* posix/regex_internal.c (re_string_skip_chars): Fix miscomputation
of remain_len that may cause incomplete multi-byte character and
false match.
* posix/bug-regex33.c: New file.
* posix/Makefile (tests): Add bug-regex33.
