An update that contains five features and has one fix can now be installed.

Description:

This update for gzip fixes the following issues:

Update from version 1.9 to version 1.10 (jsc#ECO-2217, jsc#SLE-12974)

  • Enable DFLTCC (Deflate Conversion Call) compression for s390x for levels 1-6 to CFLAGS. (jsc#SLE-13775)

Enable by adding -DDFLTCC_LEVEL_MASK=0x7e to CFLAGS. - Fix three data corruption issues. (bsc#1145276, jsc#SLE-5818, jsc#SLE-8914) - Add support for DFLTCC (hardware-accelerated deflation) for s390x arch. (jsc#SLE-5818, jsc#SLE-8914)

Enable it using the --enable-dfltcc option. - Compressed gzip output no longer contains the current time as a timestamp when the input is not a regular file.
Instead, the output contains a null (zero) timestamp. This makes gzip's behavior more reproducible when used as part of a pipeline. - A use of uninitialized memory on some malformed inputs has been fixed. - A few theoretical race conditions in signal handlers have been fixed. - Update gnulib for libio.h removal.
