5ddd2c6685 dump.f2fs: compress: fix dstlen of LZ4_compress_fast_extState()
commit 0b9b89fda2e9fbaf17a11fa15332e7ae95cf5261
category: bugfix
issue: #I6VAS0
CVE: NA

---------------------------------------

Compressed cluster content includes compress cluster header, so
calculation of dstlen parameter in LZ4_compress_fast_extState()
should consider this design, otherwise compressed data may overflow
destination buffer during compression.

ecdcd6189d f2fs-tools:sload.f2fs compression support
commit b585244e72
category: bugfix
issue: #I6VAS0
CVE: NA

---------------------------------------

Add F2FS compression support for sload
* Support file extension filter, either default-accept or default-deny
  policy
* Support choice of compression algorithm, LZO (version 2) or LZ4
  (default)
* Support custom log of cluster size
* Support minimum number of compressed blocks per cluster (default 1).
  A cluster will not be compressed if the number can not be met.
* suuport -r (read-only) option
  This releases compressed blocks to secure free space in advance. Note that,
  all compressed files will have the immutable bit.
* Added manpage update
* Remove unecessary qbuf allocation (Jaegeuk, suggested by Satya)
