The introduction of taint + tracking also did many adjustments to string handling. Since then, eximon + frequently terminated with an assert failure. + +JH/15 When PIPELINING, synch after every hundred or so RCPT commands sent and + check for 452 responses. This slightly helps the inefficieny of doing + a large alias-expansion into a recipient-limited target. The max_rcpt + transport option still applies (and at the current default, will override + the new feature). The check is done for either cause of synch, and forces + a fast-retry of all 452'd recipients using a new MAIL FROM on the same + connection. The new facility is not tunable at this time. + +JH/16 Fix the variables set by the gsasl authenticator. Previously a pointer to + library live data was being used, so the results became garbage. Make + copies while it is still usable. + +JH/17 Logging: when the deliver_time selector ise set, include the DT= field + on delivery deferred (==) and failed (**) lines (if a delivery was + attemtped). Previously it was only on completion (=>) lines. + +JH/18 Authentication: the gsasl driver not provides the $authN variables in time + for the expansion of the server_scram_iter and server_scram_salt options. + +WB/01 SPF: DNS lookups for the obsolete SPF RR type done by the libspf2 library + are now specifically given a NO_DATA response without hitting the system + resolver. The library goes on to do the now-standard TXT lookup. + Use of dnsdb lookups is not affected. + +JH/19 Bug 2507: Modules: on handling a dynamic-module (lookups) open failure, + only retrieve the errormessage once. Previously two calls to dlerror() + were used, and the second one (for mainlog/paniclog) retrieved null + information. + +JH/20 Taint checking: disallow use of tainted data for + - the appendfile transport file and directory options + - the pipe transport command + - the autoreply transport file, log and once options + - file names used by the redirect router (including filter files) + - named-queue names + Previously this was permitted. + +JH/21 Bug 2501: Fix init call in the heimdal authenticator. Previously it + adjusted the size of a major service buffer; this failed because the + buffer was in use at the time. Change to a compile-time increase in the + buffer size, when this authenticator is compiled into exim. + +JH/22 Taint checking: move to a hybrid approach for checking. Previously, one + of two ways was used, depending on a build-time flag. The fast method + relied on assumptions about the OS and libc malloc, which were known to + not hold for the BSD-derived platforms, and discovered to not hold for + 32-bit Linux either. In fact the glibc documentation describes cases + where these assumptions do not hold. The new implementation tests for + the situation arising and actively switches over from fast to safe mode. + +PP/01 Update the openssl_options possible values through OpenSSL 1.1.1c. + New values supported, if defined on system where compiled: + allow_no_dhe_kex, cryptopro_tlsext_bug, enable_middlebox_compat, + no_anti_replay, no_encrypt_then_mac, prioritize_chacha, tlsext_padding Exim version 4.93
