* [PATCH v1 1/1] iproto: fix assertion failure on invalid msgpack @ 2019-03-05 11:29 Kirill Shcherbatov 2019-03-05 14:00 ` Vladimir Davydov 0 siblings, 1 reply; 4+ messages in thread From: Kirill Shcherbatov @ 2019-03-05 11:29 UTC (permalink / raw) To: tarantool-patches, vdavydov.dev; +Cc: Kirill Shcherbatov https://github.com/tarantool/tarantool/tree/kshch/gh-3900-binary-socket-gibberish-crash https://github.com/tarantool/tarantool/issues/3900 In some cases, only the initial portion of the transmitted client request buffer is a valid msgpack.

If the flag > is set, it should raise 'packet body' error unless the packet ends > exactly at 'end'. Hi! Thank you for review. =================================================== Before the commit d9f82b176e24 "More than one row in fixheader. Zstd compression", xrow_header_decode treated everything until 'end' as the packet body while currently it allows a packet to end before 'end'. The iproto_msg_decode may receive an invalid msgpack but it still assumes that xrow_header_decode sets an error in such case and use assert to test it, bit it is not so. Introduced a new boolean flag to control routine behaviour. When flag is set, xrow_header_decode should raise 'packet body' error unless the packet ends exactly at 'end'.
