Lasse Collin a18ae42a79 liblzma: Don't verify header CRC32s if building for fuzz testing.
FUZZING_BUILD_MODE_UNSAFE_FOR_PRODUCTION is #defined when liblzma
is being built for fuzz testing.

Most fuzzed inputs would normally get rejected because of incorrect
CRC32 and the actual header decoding code wouldn't get fuzzed.
Disabling CRC32 checks avoids this problem. The fuzzer program
must still use LZMA_IGNORE_CHECK flag to disable verification of
integrity checks of uncompressed data.

Lasse Collin f76f7516d6 xzless: Rename unused variables to silence static analysers.
In this particular case I don't see this affecting readability
of the code.

Thanks to Pavel Raiskup.

Lasse Collin 3cbcaeb07e liblzma: Remove an always-true condition from lzma_index_cat().
This should help static analysis tools to see that newg
isn't leaked.

Thanks to Pavel Raiskup.

preffered instead.

Lasse Collin a1e2c568de Windows: Fix paths in VS project files.
Some paths use slashes instead of backslashes as directory

Lasse Collin a015cd1f90 xz: Fix "xz --list --robot missing_or_bad_file.xz".
It ended up printing an uninitialized char-array when trying to
print the check names (column 7) on the "totals" line.

This also changes the column 12 (minimum xz version) to
50000002 (xz 5.0.0) instead of 0 when there are no valid
input files.

Thanks to kidmin for the bug report.

Lasse Collin bba477257d xz: Use POSIX_FADV_RANDOM for in "xz --list" mode.
xz --list is random access so POSIX_FADV_SEQUENTIAL was clearly
wrong.

Lasse Collin 310d19816d liblzma: Make lzma_index_decoder_init() visible to other liblzma funcs.
This is to allow other functions to use it without going
via the public API (lzma_index_decoder()).
2017-03-30 20:03:05 +03:00
Lasse Collin a27920002d liblzma: Add generic support for input seeking (LZMA_SEEK).
Also mention LZMA_SEEK in xz/message.c to silence a warning.

Lasse Collin a0b1dda409 liblzma: Fix lzma_memlimit_set(strm, 0).
The 0 got treated specially in a buggy way and as a result
the function did nothing. The API doc said that 0 was supposed
to return LZMA_PROG_ERROR but it didn't.

Now 0 is treated as if 1 had been specified. This is done because
0 is already used to indicate an error from lzma_memlimit_get()
and lzma_memusage().

In addition, lzma_memlimit_set() no longer checks that the new
limit is at least LZMA_MEMUSAGE_BASE. It's counter-productive
for the Index decoder and was actually needed only by the
auto decoder. Auto decoder has now been modified to check for
LZMA_MEMUSAGE_BASE.

Lasse Collin 84462afaad liblzma: Similar memlimit fix for stream_, alone_, and auto_decoder. 2017-03-30 19:16:55 +03:00
Lasse Collin cbc7401793 liblzma: Fix handling of memlimit == 0 in lzma_index_decoder().
It returned LZMA_PROG_ERROR, which was done to avoid zero as
the limit (because it's a special value elsewhere), but using
LZMA_PROG_ERROR is simply inconvenient and can cause bugs.

The fix/workaround is to treat 0 as if it were 1 byte. It's
effectively the same thing. The only weird consequence is
that then lzma_memlimit_get() will return 1 even when 0 was
specified as the limit.

This fixes a very rare corner case in xz --list where a specific
memory usage limit and a multi-stream file could print the
error message "Internal error (bug)" instead of saying that
the memory usage limit is too low.

Lasse Collin d4a0462abe liblzma: Avoid multiple definitions of lzma_coder structures.
Only one definition was visible in a translation unit.
It avoided a few casts and temp variables but seems that
this hack doesn't work with link-time optimizations in compilers
as it's not C99/C11 compliant.

Lasse Collin df8f446e3a tuklib_cpucores: Add support for sched_getaffinity().
It's available in glibc (GNU/Linux, GNU/kFreeBSD). It's better
than sysconf(_SC_NPROCESSORS_ONLN) because sched_getaffinity()
gives the number of cores available to the process instead of
the total number of cores online.

As a side effect, this commit fixes a bug on GNU/kFreeBSD where
configure would detect the FreeBSD-specific cpuset_getaffinity()
but it wouldn't actually work because on GNU/kFreeBSD it requires
using -lfreebsd-glue when linking. Now the glibc-specific function
will be used instead.

Thanks to Sebastian Andrzej Siewior for the original patch
and testing.

Lasse Collin 446e4318fa xz: Fix copying of timestamps on Windows.
xz used to call utime() on Windows, but its result gets lost
on close(). Using _futime() seems to work.

It silences a few warnings and most people probably have
0.19 even on stable distributions.
