| Summary | 0008796: aligned member accesses to misaligned GNUNET_MESSENGER_RoomEntryRecord | ||||
| Description | If one builds gnunet with --enable-sanitizer, and then uses that gnunet to build libgnunetchat, and runs the libgnunetchat tests with UBSAN_OPTIONS=print_stacktrace=1, they will see the attached test log. In summary, there are two places where unaligned accesses are occurring: in messenger_value_to_string in plugin_gnsrecord_messenger, and inside idx_of in container_multihashmap.c, called by libgnunetchat in handle_process_records in gnunet_chat_handle.c. The latter could be considered a bug in libgnunetchat, but the former is purely in gnunet. | ||||
| Steps To Reproduce | 1. build and install gnunet 0.21.1 with --enable-sanitizer (recent patches will be required to make gnunet's test suite pass) 2. build libgnunetchat 0.3.1, run the test suite (the unaligned accesses in libgnunetchat itself will only show up if you have CFLAGS=-fsanitize=address,undefined like me, but the unaligned accesses in gnunet itself should show up either way) with UBSAN_OPTIONS=print_stacktrace=1 set in the test environment 3. observe attached output in meson-logs/testlog.txt | ||||
| Additional Information | It doesn't seem like there's much we can do about the GNUNET_MESSENGER_RoomEntryRecord itself being unaligned, since it's presumably encapsulated inside another message. We can get gcc to safely handle unaligned member access by using GNUNET_PACKED in the struct definition, but while this will help with direct member accesses, it won't help with indirect member accesses (e.g. using the address of a member). The only solution I can see for those is to produce an aligned copy of the member, e.g. a copy of the GNUNET_MESSENGER_RoomEntryRecord.key member that requires 4-byte alignment. The first patch attached adds GNUNET_PACKED to the struct definition in gnunet, while the second patch attached uses an aligned temporary copy of the room key inside handle_process_records. This is at least enough to make the libgnunetchat tests pass, though I haven't tried using it further yet. | ||||

I think `struct GNUNET_PeerIdentity` shouldn't have any alignment required since it's storing an array of unsigned char with alignment of 1. So making the key be packed and copying in libgnunetchat sounds reasonable. |

Resolved upstream in gnunet as well as libgnunetchat. |
