404a7bfed0 moved again overflow correction
cannot work from within ZSTD_compressBlock()
2018-09-26 18:06:53 -07:00

0e2dbac18a changed overflow correction place
keep one in compress_frameChunk(),
so that it's tested at every loop
in case some user simply some large mulit-GB input in a single invocation.

Add one in ZSTD_compressBlock(),
since compressBlock() explicitly skips frameChunk().

f98c69d77c fix : huge (>4GB) stream of blocks
experimental function ZSTD_compressBlock() is designed for very small data in mind,
for situation where saving the ~12 bytes of frame header can actually make a difference.

Some systems though may have to deal with small and large data entangled.
If it's larger than a block (> 128KB), compressBlock() cannot compress them in one round.

That's why it's possible to compress in multiple rounds.
This is a chain of compressed blocks.

Some users push this capability to the limit, encoding gigantic chain of blocks.
On crossing the 4GB limit, some internal overflow occurs.

This fix moves the overflow correction mechanism higher in the call chain,
so that it's applied also to gigantic chains of blocks.

Added a test case in fuzzer.c, which crashes before the fix, and pass now.

5e580de6da [zstd] Fix seqStore growth
We could undersize the literals buffer by up to 11 bytes,
due to a combination of 2 bugs:
* The literals buffer didn't have `WILDCOPY_OVERLENGTH` extra
  space, like it is supposed to.
* We didn't check the literals buffer size in `ZSTD_sufficientBuff()`.
