Can you show me which patch fixed the problem in LZO? https://web.git.kernel.org/pub/scm/linux/kernel/git/herbert/cryptodev-2.6.git/commit/?id=cc47f07234f72cbd8e2c973cdbf2a6730660a463 > Does LZO guarantee the output data length smaller than input buffer length? > Which commit fixed the issue? The guarantee is that the algorithm will not write to the output buffer beyond the specific buffer length. For compression, you may specify a desired output length that is smaller than the input buffer, automatically stopping the compression if the input is incompressible.
