--- Begin Message ---Source: libarchive Version: 3.7.2-2 Severity: normal X-Debbugs-Cc: [email protected], [email protected] Control: affects -1 src:e2fsprogs Hi, the upload of e2fsprogs 1.47.1~rc1-1 to unstable yesterday uses a new feature where libarchive is used to create filesystem images from tarballs. This works on all architectures (main as well as ports) except on mips64el: https://buildd.debian.org/status/package.php?p=e2fsprogs I attached a minimal reproducer. It includes an embedded gzipped tarball with a single file called "myfilename" of size 10. It works fine if _FILE_OFFSET_BITS is not set but with it, it reports a wrong archive member size of zero on mips64el: $ gcc -Wall -g -O0 libarchivetest.c -larchive -D_FILE_OFFSET_BITS=64 $ ./a.out myfilename: 0 Since the reproducer only makes use of libarchive, I'm filing this as a libarchive bug. Since this problem is mips64el specific, I'm putting the porter-list in X-Debbugs-Cc. The problem can also be reproduced on bookworm. gdb can show what is going on (thanks to Theodore Ts'o for the initial debugging): (gdb) run [...] Breakpoint 1, main () at test.c:49 49 st = archive_entry_stat(entry); (gdb) next 50 fprintf(stderr, "%s: %ld\n", archive_entry_pathname(entry), st->st_size); (gdb) p *st $2 = {st_dev = 1, st_pad1 = {0, 0, 0}, st_ino = 1, st_mode = 33188, st_nlink = 0, st_uid = 1000, st_gid = 1000, st_rdev = 0, st_pad2 = {0, 0, 10}, st_size = 0, st_atim = {tv_sec = 0, tv_nsec = 0}, st_mtim = {tv_sec = 1714375615, tv_nsec = 0}, st_ctim = {tv_sec = 0, tv_nsec = 0}, st_blksize = 0, st_pad4 = 0, st_blocks = 0, st_pad5 = {0 <repeats 14 times>}} As one can see, the size "10" is not in st_size but in the padding before the st_size member. This only happens when _FILE_OFFSET_BITS=64 and only on mips64el. Any idea what is going on with mips64el?
