The Squid HTTP Proxy team is very pleased to announce the availability of the Squid-184.108.40.206 beta release! This release includes major changes to the TCP handling layer of Squid.As a result of the low level and wide impact of this change this beta is less stable than previous releases.
The daily snapshot already includes several important behaviour fixes and is recommended for testing instead of the version marker bundle. With your assistance tracking down the new bugs we hope this can be a very short lived instability.
We have traded this step down to gain: * Support split-stack IPv6 to serversThis is expected to resolved most if not all outstanding IPv6 issues on OpenBSD, NetBSD, MacOSX and other systems with redacted TCP stack capabilities. Failure recovery in the event of broken external services is greatly enhanced, although further improvement is possible.
* Support persistent connections with tcp_outgoing_addressPersistent connections are now expected to be picked reliably despite any forced outgoing IP. This also resolves all issues around tcp_outgoing_address ACL not having access to the destination IP for use in the dst ACL.
* Optimize persistent connection handling * Optimize FTP data connection handling * Optimize TCP failure recoveryThis release is expected to pool and re-use connections more efficiently than ever before. Resolving several outstanding issues with unnecessarily high connection counts to peers, resolving FTP data connection failures and much faster TCP connection retry stages. A new directive connect_retries is added to limit the absolute number of routing paths to attempt on each requests before presenting an error page to the user.
Also added some HTTP/1.1 support fixes and extra logformat tags for display of the HTTP request line received from the client and sent to the server.
As usual this release contains all the fixes passed on to 3.1 series alongside its own changes. There are several important bugs fixed amongst those changes:
* A small security vulnerability in the ssl-bump certificate validation. This only affects those choosing to bypass certificate failures.
* Several squid.conf parsing segmentation faults fixed. See the ChangeLog for the list of other minor changes in this release.All users interested in 3.2 features are encouraged to assist testing this release.
