-Subject: libdwfl: Rewrite reading of ar_size in elf_begin_rand
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-With GCC 12.1.1, glibc 2.35, -fsanitize=undefined and
--D_FORTIFY_SOURCE=3 we get the following error message:
-
-In file included from /usr/include/ar.h:22,
- from ../libelf/libelfP.h:33,
- from core-file.c:31:
-In function ‘pread’,
- inlined from ‘pread_retry’ at ../lib/system.h:188:21,
- inlined from ‘elf_begin_rand’ at core-file.c:86:16,
- inlined from ‘core_file_read_eagerly’ at core-file.c:205:15:
-/usr/include/bits/unistd.h:74:10: error: ‘__pread_alias’ writing 58 or more bytes into a region of size 10 overflows the destination [-Werror=stringop-overflow=]
- 74 | return __glibc_fortify (pread, __nbytes, sizeof (char),
- | ^~~~~~~~~~~~~~~
-/usr/include/ar.h: In function ‘core_file_read_eagerly’:
-/usr/include/ar.h:41:10: note: destination object ‘ar_size’ of size 10
- 41 | char ar_size[10]; /* File size, in ASCII decimal. */
- | ^~~~~~~
-/usr/include/bits/unistd.h:50:16: note: in a call to function ‘__pread_alias’ declared with attribute ‘access (write_only, 2, 3)’
- 50 | extern ssize_t __REDIRECT (__pread_alias,
- | ^~~~~~~~~~
-cc1: all warnings being treated as errors
-
-The warning disappears when dropping either -fsanitize=undefined
-or when using -D_FORTIFY_SOURCE=2. It looks like a false positive.
-But I haven't figured out how/why it happens.
-
-The code is a little tricky to proof correct though. The ar_size
-field is a not-zero terminated string ASCII decimal, right-padded
-with spaces. Which is then converted with strtoll. Relying on the
-fact that the struct ar_hdr is zero initialized, so there will be
-a zero byte after the ar_size field.
-
-Rewrite the code to just use a zero byte terminated char array.
-Which is much easier to reason about. As a bonus the error disappears.
