(from ebtree 6.0.7) Julien Thomas provided a reproducible test case where a string lookup could return the wrong node. The issue is caused by the jump to a node which contains less bit in common than the previous node, making the string_equal_bits() function return -1. We must not remember more bits than the number on the node, otherwise we can be tempted to trust them while they can change while running down. For a valid test case, enter : "0", "WW", "W", "S", and lookup "W". Previously, "S" was returned. Note: string-based ebtrees are used in haproxy in ACL, peers and stick-tables. ACLs are not affected because all patterns are interchangeable. stick-tables are not affected because lookups are performed using ebmb_lookup(). Only peers might be affected though it is not easy to infirm or confirm the issue. (cherry picked from commit dd47a54103597458887d3cc8414853a541aee9c1) |
