Denys Vlasenko	3989e5adf4	unlzma: fix erroneous "while" instead of "if". Closes 4682 These parts of the code essentially check whether stepping back by rep0 goes negative or not. LZMA SDK from lzma1604.7z has the following in the corresponding places: ... = dic[dicPos - rep0 + (dicPos < rep0 ? dicBufSize : 0)] Clearly, not loop here. Technically, "while" here works: if condition is false (because pos underflowed), it iterates once, adds header.dict_size (a.k.a. dicBufSize), this makes pos positive but smaller than header.dict_size, and loop exits. Now we'll just check for negative result of subtraction, which is less code: function old new delta unpack_lzma_stream 2659 2641 -18 (I hope 2 Gbyte+ dictionaries won't be in use soon).

Kang-Che Sung	d5e7ff0292	bunzip2: fix code bloat caused by zcat's seamless magic This example single-applet configuration would trigger the bloat: CONFIG_FEATURE_SEAMLESS_XZ=y CONFIG_FEATURE_SEAMLESS_LZMA=y CONFIG_FEATURE_SEAMLESS_BZ2=y CONFIG_FEATURE_SEAMLESS_GZ=y CONFIG_BUNZIP2=y # CONFIG_ZCAT is not set # All other applets disabled Here, the resulting "busybox-bunzip2" binary would contain unpack_gz_stream, unpack_lzma_stream and unpack_xz_stream functions code. In other words, the gzip, lzma and xz decompressors' code are linked into the binary unnecessarily. This happens because SEAMLESS_MAGIC != 0 and compiler is unable to figure out that SEAMLESS_MAGIC bit is never set. Fix this by disabling SEAMLESS_MAGIC option flag (setting its value to 0) when zcat is disabled. This will help the compiler optimize out bbunpack() and no longer generate open_zipped() function call.

Rich Felker	7f7ade1964	gzip: do not store timestamp in gzip header Storing the original file's modification time in the output file is harmful (precludes deterministic results) and unlike official gzip, the busybox version provides no way to suppress this behavior; the -n option is silently ignored. Rather than trying to make -n work, this patch just removes the timestamp-storing functionality. It should be considered deprecated anyway; it's not Y2038-safe and gunzip ignores it by default. Per RFC 1952, 0 is the correct value to store to indicate that there is no timestamp.

Lasse Collin	c3045edec2	xz: fix incorrect XZ_BUF_ERROR xz_dec_run() could incorrectly return XZ_BUF_ERROR if all of the following was true: - The caller knows how many bytes of output to expect and only provides that much output space. - When the last output bytes are decoded, the caller-provided input buffer ends right before the LZMA2 end of payload marker. So LZMA2 won't provide more output anymore, but it won't know it yet and thus won't return XZ_STREAM_END yet. - A BCJ filter is in use and it hasn't left any unfiltered bytes in the temp buffer. This can happen with any BCJ filter, but in practice it's more likely with filters other than the x86 BCJ. This fixes <https://bugzilla.redhat.com/show_bug.cgi?id=735408> where Squashfs thinks that a valid file system is corrupt. Thanks to Jindrich Novy for telling me that such a bug report exists, Phillip Lougher for providing excellent debug info, and other people on #fedora-ppc. This also fixes a similar bug in single-call mode where the uncompressed size of a XZ Block using BCJ + LZMA2 was 0 bytes and caller provided no output space. Many empty .xz files don't contain any Blocks and thus don't trigger this bug. This also tweaks a closely related detail: xz_dec_bcj_run() could call xz_dec_lzma2_run() to decode into temp buffer when it was known to be useless. This was harmless although it wasted a minuscule number of CPU cycles.
