Hi, HAProxy 1.8.26 was released on 2020/08/03. It added 71 new commits after version 1.8.25.
The previous release is 4 months old, so the list of fixes is a bit large. Most of these were already mentioned over the last releases. The most noticeable are: - Some crashes were fixed with the unique-id, the http_first_req, and the capture.* sample fetches when called without a stream. - The "http-check send" keyword was backported, it allows you to add extra headers and payload in your HTTP checks. - A bug with the no-check-ssl option was fixed. - A really old bug was found in the shctx lock code, making the process crash when there is a lot of lock contention on the cache. The shctx code is also used for the SSL sessions cache but there is less chance to provoke this problem. - An HTTP reuse issue was fixed when using NTML authentication, this was fixed by using a safer test for making the NTML sessions private. - A memory leak in the DNS code was fixed. The DNS answer items attached to a resolution were not released when the DNS resolution was freed. - Lua operations performed on map or acl files (set/add/del) are now thread-safe. And the analyze timeout is now reset before executing a lua action to avoid a loop because of a not updated expired timeout. - In the H2 multiplexer, when an chunked H1 response is parsed before sending it to the client, if a chunk size or a chunk CRLF is incomplete, an error is now triggered and an RST_STREAM is sent to the client with the ROTOCOL_ERROR error code. It may happens if the server closes the connection, because the remaining incomplete data are unconditionally forwarded. Without this fix, nothing is parsed, leading to a infinite loop in the h2_snd_buf() function. - Some inconsistencies in the argument parser were fixed, the parameter of all options now support a hyphen as a first character except the -sf/st ones. We also fixed the support of the "--" option in the mworker mode, which is useful at the end of the command when you want to use a list of configuration files. - The url_dec converter now takes an optional argument to specify if the input string is part of a form or a query-string to adapt the decoding. - A thread-safety issue was fixed in the pattern matching code. - The hdr_ip() sample fetch now properly parses IPv4 addresses without a NULL character delimiter. - The memcmp() in ebtree was replaced by a byte-per-byte memcmp() to compare memory blocks because memcmp() was dangerous as it could read past the end on implementations that read multiple bytes at a time. - A risk of looping (and abort) on channels that's triggered at least by Lua cosockets attempting to read a complete line from truncated contents was fixed. - String comparisons with patterns (ACLs, ...) were performed by adding a trailing nul character but didn't check if it would fit, occasionally causing crashes (e.g. comparison with ALPN). Now short patterns are duplicated first. This list is not exhaustive. Please have a look at the changelog below for the complete list of fixes, and do not forget to update.
