head: fix processing of non-seekable input as seekable

2016-11-28T18:36:32Z

* src/head.c (elide_tail_bytes_file): Ensure we don't use st_size unless we've previously used seek() to determine the CURRENT_POS in the seekable file. This was seen to cause issue on FreeBSD 11 when the pipe buffer was filled with `yes | head --lines=-0`, in which case st_size was 64KiB while ST_BLKSIZE() was 4KiB. Reported by Assaf Gordon.

install,mkdir: fix handling of -DZ and -pZ, respectively

2016-11-28T16:17:31Z

... in the case where two or more directories nested in each other are created and each of them defaults to a different SELinux context. * src/install.c (make_ancestor): When calling defaultcon(), give it the same path that is given to mkdir(). The other path is not always valid wrt. current working directory. * src/mkdir.c (make_ancestor): Likewise. * NEWS: Mention the bug fix. Reported at https://bugzilla.redhat.com/1398913

tac: fix mem corruption when failing to read non seekable inputs

2016-11-28T13:19:24Z

This was detected with ASAN, but can also be seen without ASAN with: $ tac - - <&- tac: standard input: read error: Bad file descriptor *** Error in `tac': malloc(): memory corruption: 0x... * src/tac.c (copy_to_temp): Don't close our output stream on (possibly transient) output error, or on input error. (temp_stream): clearerr() on the stream about to be reused, to ensure future stream use is not impacted by transient errors. * tests/misc/tac-2-nonseekable.sh: Add a test case. * NEWS: Mention the bug fix. Fixes http://bugs.gnu.org/25041

tail: fix uninitialized memory read when failing to read file

2016-11-27T21:10:15Z

Reproduced under UBSAN with `tail -f <&-` giving: tail.c:2220:18: runtime error: load of value 190, which is not a valid value for type ‘_Bool' * src/tail.c (tail_file): Ensure f->ignore is initialized in all cases where we can't tail the specified file. * tests/tail-2/follow-stdin.sh: Add a test case which checks stderr has no UBSAN warnings. Fixes http://bugs.gnu.org/25041

stat,tail: sync with latest Linux file systems

2016-11-27T00:28:16Z

Update with the results from: kgit='https://git.kernel.org/cgit/linux/kernel/git' wget -q $kgit/torvalds/linux.git/plain/include/uapi/linux/magic.h \ -O src/fs-latest-magic.h make src/fs-magic-compare * src/stat.c (human_fstype): Add entries for: BALLOON_KVM, CGROUP2, DAXFS, ZSMALLOC.

build: fix potential factor build failure on arm and risc

2016-11-27T00:28:16Z

* src/longlong.h: Sync from gmp repo incorporating: Protect umul_ppmm with do ... while (0) Replace obsolete ARC asm 'J' constraints with 'Cal' Provide umul_ppmm for riscv64

shred,sort: ensure faster unaligned access to rand module

2016-11-27T00:27:45Z

glibc has changed the public define from _STRING_ARCH_unaligned to _STRING_INLINE_unaligned as per https://sourceware.org/bugzilla/show_bug.cgi?id=19462 * gl/lib/rand-isaac.c: Cater for both defines. * gl/lib/randread.c: Likewise. * src/system.h: Update commented out code.

numfmt: pacify Sun C 5.14

2016-11-26T02:54:32Z

* src/numfmt.c (main): Don't implicitly coerce pointer in bool initializer. Although it's portable C99 code, it's confusing.

pr: fix read from invalid memory with tabs in separator

2016-11-25T14:08:42Z

This was detected with: echo a > a; pr "-S$(printf "\t\t\t")" a -m a > /dev/null Resulting in ASAN triggering: ==================================================== ERROR: AddressSanitizer: global-buffer-overflow READ of size 1 at 0x00000041b622 thread T0 #0 0x40506a in print_sep_string ../src/pr.c:2241 #1 0x407ec4 in read_line ../src/pr.c:2493 #2 0x40985c in print_page ../src/pr.c:1802 #3 0x40985c in print_files ../src/pr.c:1618 #4 0x4036e0 in main ../src/pr.c:1136 * src/pr.c (init_parameters): Ensure we only override the specified separator when it's a single tab, thus matching the calculated separator length. * tests/pr/pr-tests.pl: Add a test case. * NEWS: Mention the fix.

ptx: fix an invalid heap reference with short --width

2016-11-24T16:21:59Z

* src/ptx.c (fix_output_parameters): Ensure line_width doesn't go negative, which can happen when the --width is less than the --gap-size. * tests/misc/ptx-overrun.sh: Add a test case that triggers with ASAN. (Note the longer filename is needed to trigger). Fixes http://bugs.gnu.org/25011
