All relay operators running earlier 0.3.2.x versions should + upgrade. This version also includes a mitigation for over-full DESTROY + queues leading to out-of-memory conditions: if it works, we will soon + backport it to earlier release series. + + This is the second release candidate in the 0.3.2 series. If we find no + new bugs or regression here, then the first stable 0.3.2 release will + be nearly identical to this. + + o Major bugfixes (KIST, scheduler): + - The KIST scheduler did not correctly account for data already enqueued + in each connection's send socket buffer, particularly in cases when the + TCP/IP congestion window was reduced between scheduler calls. This + situation lead to excessive per-connection buffering in the kernel, and + a potential memory DoS. Fixes bug 24665; bugfix on 0.3.2.1-alpha. + + o Minor bugfixes (scheduler, KIST): + - Use a sane write limit for KISTLite when writing onto a connection + buffer instead of using INT_MAX and shoving as much as it can. Because + the OOM handler cleans up circuit queues, we are better off at keeping + them in that queue instead of the connection's buffer. Fixes bug 24671; + bugfix on 0.3.2.1-alpha. + + o Minor features (geoip): + - Update geoip and geoip6 to the December 6 2017 Maxmind GeoLite2 + Country database. + + o Minor bugfixes (hidden service v3): + - Bump hsdir_spread_store parameter from 3 to 4 in order to increase the + probability of reaching a service for a client missing microdescriptors. + Fixes bug 24425; bugfix on 0.3.2.1-alpha. + + o Minor bugfixes (memory usage): + - When queuing DESTROY cells on a channel, only queue the + circuit-id and reason fields: not the entire 514-byte + cell. This fix should help mitigate any bugs or attacks that + fill up these queues, and free more RAM for other uses. Fixes + bug 24666; bugfix on 0.2.5.1-alpha. + + + Changes in version 0.3.2.7-rc - 2017-12-14 Tor 0.3.2.7-rc fixes various bugs in earlier versions of Tor, including some that could affect reliability or correctness. diff --git a/changes/bug24665 b/changes/bug24665 deleted file mode 100644 index f950d9dd0..000000000 --- a/changes/bug24665 +++ /dev/null @@ -1,6 +0,0 @@ - o Major bugfixes (KIST, scheduler): - - The KIST scheduler did not correctly account for data already enqueued - in each connection's send socket buffer, particularly in cases when the - TCP/IP congestion window was reduced between scheduler calls.
