Bugfix release.
Security issue: When enabling SASL authentication for binary protocol, enabling UDP mode would allow bypassing SASL. Now refuses to start with both UDP and SASL enabled. Text mode authentication was not vulnerable.
Includes a performance improvement for page rebalancing. Full discussion here: https://github.com/memcached/memcached/pull/524 - in some circumstances, page will be moved between slab classes much faster than before.
- Security fix: Don't allow UDP with binprot SASL
- Remove multiple double-initializations of condition variables and mutexes
- Fix data race in
assoc_start_expand - Use a proper data type for
settings.sig_hup - restart: add error handling when a tag is not found in a metadata file.
- doc: Update rfc2629.dtd, use local copy, fix error, and fix warning
- doc: Fix out-of-tree build
- slab rebalance performance improvements
- fix potential deadlock bug in log watcher
- Support running tests in out-of-tree build
- configure: Fix cross-compilation errors
- DTrace build fix
