Andrew Kryczka a79c7c05e8 fix backup meta-file buffer overrun ... Summary: - check most times after calling snprintf that the buffer didn't fill up. Previously we'd proceed and use `buf_size - len` as the length in subsequent calls, which underflowed as those are unsigned size_t. - replace some memcpys with snprintf for consistency Closes https://github.com/facebook/rocksdb/pull/3255 Differential Revision: D6541464 Pulled By: ajkr fbshipit-source-id: 8610ea6a24f38e0a37c6d17bc65b7c712da6d932		2017-12-15 12:29:16 -08:00
