Co-authored-by: Emmanuel T Odeke <emmanuel@orijtech.com> Closes #5907 - add init-corpus to blockchain reactor - remove validator-set FromBytes test now that we have proto, we don't need to test it! bye amino - simplify mempool test do we want to test remote ABCI app? - do not recreate mux on every crash in jsonrpc test - update p2p pex reactor test - remove p2p/listener test the API has changed + I did not understand what it's tested anyway - update secretconnection test - add readme and makefile - list inputs in readme - add nightly workflow - remove blockchain fuzz test EncodeMsg / DecodeMsg no longer existpull/6085/head

# fuzz | |||||
Fuzzing for various packages in Tendermint using [go-fuzz](https://github.com/dvyukov/go-fuzz) library. | |||||
Inputs: | |||||
- mempool `CheckTx` (using kvstore in-process ABCI app) | |||||
- p2p `Addrbook#AddAddress` | |||||
- p2p `pex.Reactor#Receive` | |||||
- p2p `SecretConnection#Read` and `SecretConnection#Write` | |||||
- rpc jsonrpc server | |||||
## Directory structure | |||||
``` | |||||
| test | |||||
| |- corpus/ | |||||
| |- crashers/ | |||||
| |- init-corpus/ | |||||
| |- suppressions/ | |||||
| |- testdata/ | |||||
| |- <testname>.go | |||||
``` | |||||
`/corpus` directory contains corpus data. The idea is to help the fuzzier to | |||||
understand what bytes sequences are semantically valid (e.g. if we're testing | |||||
PNG decoder, then we would put black-white PNG into corpus directory; with | |||||
blockchain reactor - we would put blockchain messages into corpus). | |||||
`/init-corpus` (if present) contains a script for generating corpus data. | |||||
`/testdata` directory may contain an additional data (like `addrbook.json`). | |||||
Upon running the fuzzier, `/crashers` and `/suppressions` dirs will be created, | |||||
along with <testname>.zip archive. `/crashers` will show any inputs, which have | |||||
lead to panics (plus a trace). `/suppressions` will show any suppressed inputs. | |||||
## Running | |||||
```sh | |||||
make fuzz-mempool | |||||
make fuzz-p2p-addrbook | |||||
make fuzz-p2p-pex | |||||
make fuzz-p2p-sc | |||||
make fuzz-rpc-server | |||||
``` | |||||
Each command will create corpus data (if needed), generate a fuzz archive and | |||||
call `go-fuzz` executable. | |||||
Then watch out for the respective outputs in the fuzzer output to announce new | |||||
crashers which can be found in the directory `crashers`. | |||||
For example if we find | |||||
```sh | |||||
ls crashers/ | |||||
61bde465f47c93254d64d643c3b2480e0a54666e | |||||
61bde465f47c93254d64d643c3b2480e0a54666e.output | |||||
61bde465f47c93254d64d643c3b2480e0a54666e.quoted | |||||
da39a3ee5e6b4b0d3255bfef95601890afd80709 | |||||
da39a3ee5e6b4b0d3255bfef95601890afd80709.output | |||||
da39a3ee5e6b4b0d3255bfef95601890afd80709.quoted | |||||
``` | |||||
the crashing bytes generated by the fuzzer will be in | |||||
`61bde465f47c93254d64d643c3b2480e0a54666e` the respective crash report in | |||||
`61bde465f47c93254d64d643c3b2480e0a54666e.output` | |||||
and the bug report can be created by retrieving the bytes in | |||||
`61bde465f47c93254d64d643c3b2480e0a54666e` and feeding those back into the | |||||
`Fuzz` function. |
