ncb_is_empty() was plainly incorrect as it directly dereferences the memory to read offset blocks instead of ncb_read_off(). The result is undefined. Also, BUG_ON() statement is wrong when the buffer starts with a data block. In this case, ncb_head() is not the first gap offset but instead just random data. The calculated sum in BUG_ON() statement has thus no meaning and may cause an abort. Adjust this by reorganizing the whole function. Only the first data block size is read. If and only if not nul, the first gap size is then checked. ncb_is_full() has been rewritten to share the same model as ncb_is_empty().
The HAProxy documentation has been split into a number of different files for ease of use. Please refer to the following files depending on what you're looking for : - INSTALL for instructions on how to build and install HAProxy - BRANCHES to understand the project's life cycle and what version to use - LICENSE for the project's license - CONTRIBUTING for the process to follow to submit contributions The more detailed documentation is located into the doc/ directory : - doc/intro.txt for a quick introduction on HAProxy - doc/configuration.txt for the configuration's reference manual - doc/lua.txt for the Lua's reference manual - doc/SPOE.txt for how to use the SPOE engine - doc/network-namespaces.txt for how to use network namespaces under Linux - doc/management.txt for the management guide - doc/regression-testing.txt for how to use the regression testing suite - doc/peers.txt for the peers protocol reference - doc/coding-style.txt for how to adopt HAProxy's coding style - doc/internals for developer-specific documentation (not all up to date)
