Hi,
HAProxy 2.3.5 was released on 2021/02/06. It added 54 new commits
after version 2.3.4.
There's no critical bug in this one but fixes for a few problematic cases
that either have been there for a while or resulted from recent incomplete
fixes:
- an issue in filters (compression, spoe, etc) could block response
headers in empty responses with no content-length ;
- there was a risk of temporary CLOSE_WAIT on aborted H2 connections since
the recent fixes for truncated responses. Note that these ones would
vanish on timeout anyway, hence it was more annoying than dramatic ;
- a rare risk of segfault in idle connections code related to accidental
reuse of a TCP connection involving a pending handshake was fixed ;
- the CLI's "abort ssl cert" would purge the old instead of new SSL info;
- errors on connections would not prevent SSL handshake from being
performed, leading to wasted CPU cycles that could sometimes maintain
the load artificially high during contention ;
- Lua's core.get_info() got broken in previous version due to the missing
definition of INF_BUILD_INFO in stats ;
- there was a small risk of crash in tcpchecks when using multiple
connections ;
- the previous fix for DNS SRV records was incorrect and had to be
reverted in 2.3.4 as it was sometimes causing a bad pointer
dereference and crashing. The code was rechecked and the correct
fix merged again ;
- an alignment issue in the XXHash code affecting ARMv6/v7 running
in 32-bit mode on 64-bit kernels was addressed ; it could cause
bus errors and crashes in 32-bit chroots or containers when using
the pattern LRU cache ;
- a few other really minor issues were addressed
- "server" definitions in "frontend" sections were mistakenly not
rejected during parsing, but would generally result in random crashes
later due to uninitialised fields. They are now properly rejected.
In addition, the maximum HTTP/1 chunk size was extended from 2 GB to 4 PB
since there was no more compelling reason to limit ourselves to 32 bits
storage anymore. Last, some of the "show fd" output improvements were
backported as they significantly help when reporting bugs.
2.2.9 is imminent as well with essentially the same fixes, I just don't
know yet if my backport of the tcpcheck fix is correct and don't want
to take any risks :-)
