Previously, we would sometimes treat a full + buffer as an error. Fixes bug 22628; bugfix on 0.3.1.1-alpha. + + o Major bugfixes (directory protocol): + - Ensure that we send "304 Not modified" as HTTP status code when a + client is attempting to fetch a consensus or consensus diff, and + the best one we can send them is one they already have. Fixes bug + 22702; bugfix on 0.3.1.1-alpha. + + o Major bugfixes (entry guards): + - When starting with an old consensus, do not add new entry guards + unless the consensus is "reasonably live" (under 1 day old).

Fixes bug 22626; bugfix + on 0.3.1.1-alpha. + - When decompressing a buffer, check for extra data after the end of + the compressed data. Fixes bug 22629; bugfix on 0.3.1.1-alpha. + - When decompressing an object received over an anonymous directory + connection, if we have already decompressed it using an acceptable + compression method, do not reject it for looking like an + unacceptable compression method. Fixes part of bug 22670; bugfix + on 0.3.1.1-alpha. + - When serving directory votes compressed with zlib, do not claim to + have compressed them with zstd. Fixes bug 22669; bugfix + on 0.3.1.1-alpha. + - When spooling compressed data to an output buffer, don't try to + spool more data when there is no more data to spool and we are not + trying to flush the input. Previously, we would sometimes launch + compression requests with nothing to do, which interferes with our + 22672 checks. Fixes bug 22719; bugfix on 0.2.0.16-alpha. + + o Minor bugfixes (defensive programming): + - Detect and break out of infinite loops in our compression code. We + don't think that any such loops exist now, but it's best to be + safe. Closes ticket 22672. + - Fix a memset() off the end of an array when packing cells. This + bug should be harmless in practice, since the corrupted bytes are + still in the same structure, and are always padding bytes, + ignored, or immediately overwritten, depending on compiler + behavior. Nevertheless, because the memset()'s purpose is to make + sure that any other cell-handling bugs can't expose bytes to the + network, we need to fix it. Fixes bug 22737; bugfix on + 0.2.4.11-alpha.

Fixes bug + 22516; bugfix on 0.2.5.4-alpha. + - Fix a crash in the LZMA module, when the sandbox was enabled, and + liblzma would allocate more than 16 MB of memory. We solve this by + bumping the mprotect() limit in the sandbox module from 16 MB to + 20 MB. Fixes bug 22751; bugfix on 0.3.1.1-alpha. + + o Minor bugfixes (logging): + - When decompressing, do not warn if we fail to decompress using a + compression method that we merely guessed. Fixes part of bug + 22670; bugfix on 0.1.1.14-alpha. + - When decompressing, treat mismatch between content-encoding and + actual compression type as a protocol warning. Fixes part of bug + 22670; bugfix on 0.1.1.9-alpha. + - Downgrade "assigned_to_cpuworker failed" message to info-level + severity. In every case that can reach it, either a better warning + has already been logged, or no warning is warranted. Fixes bug + 22356; bugfix on 0.2.6.3-alpha. + - Demote a warn that was caused by libevent delays to info if + netflow padding is less than 4.5 seconds late, or to notice + if it is more (4.5 seconds is the amount of time that a netflow + record might be emitted after, if we chose the maximum timeout). + Fixes bug 22212; bugfix on 0.3.1.1-alpha. + + o Minor bugfixes (process behavior): + - When exiting because of an error, always exit with a nonzero exit + status. Previously, we would fail to report an error in our exit + status in cases related to __OwningControllerProcess failure, + lockfile contention, and Ed25519 key initialization. Fixes bug + 22720; bugfix on versions 0.2.1.6-alpha, 0.2.2.28-beta, and + 0.2.7.2-alpha respectively. Reported by "f55jwk4f"; patch + from "huyvq". + + o Documentation: + - Add a manpage description for the key-pinning-journal file. Closes + ticket 22347. + - Correctly note that bandwidth accounting values are stored in the + state file, and the bw_accounting file is now obsolete. Closes + ticket 16082. + - Document more of the files in the Tor data directory, including + cached-extrainfo, secret_onion_key{,_ntor}.old, hidserv-stats, + approved-routers, sr-random, and diff-cache.
