The stktable_data union is made of types of varying sizes, and depending on which types are stored in a table, some offsets might not necessarily be aligned. This results in a bus error for certain regtests (e.g. lb-services) on MIPS64. This bug may impact MIPS64, SPARC64, armv7 when accessing a 64-bit counter (e.g. bytes) and depending on how the compiler emitted the operation, and cause a trap that's emulated by the OS on RISCV (heavy cost). x86_64 and armv8 are not affected at all. Let's properly mark the struct with __attribute__((packed)) so that the compiler emits the suitable unaligned-compatible instructions when accessing the fields. This should be backported to all versions where it applies.
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)
