*************************************************************************
|
|
**
|
|
** This is a utility program designed to aid running the SQLite library
|
|
** against an external fuzzer, such as American Fuzzy Lop (AFL)
|
|
** (http://lcamtuf.coredump.cx/afl/). Basically, this program reads
|
|
** SQL text from standard input and passes it through to SQLite for evaluation,
|
|
** just like the "sqlite3" command-line shell. Differences from the
|
|
** command-line shell:
|
|
**
|
|
** (1) The complex "dot-command" extensions are omitted. This
|
|
** prevents the fuzzer from discovering that it can run things
|
|
** like ".shell rm -rf ~"
|
|
**
|
|
** (2) The database is opened with the SQLITE_OPEN_MEMORY flag so that
|
|
** no disk I/O from the database is permitted. The ATTACH command
|
|
** with a filename still uses an in-memory database.
|
|
**
|
|
** (3) The main in-memory database can be initialized from a template
|
|
** disk database so that the fuzzer starts with a database containing
|
|
** content.
|
|
**
|
|
** (4) The eval() SQL function is added, allowing the fuzzer to do
|
|
** interesting recursive operations.
|
|
**
|
|
** (5) An error is raised if there is a memory leak.
|
|
**
|
|
** The input text can be divided into separate test cases using comments
|
|
** of the form:
|
|
**
|
|
** |****<...>****|
|
|
**
|
|
** where the "..." is arbitrary text. (Except the "|" should really be "/".
|
|
** "|" is used here to avoid compiler errors about nested comments.)
|
|
** A separate in-memory SQLite database is created to run each test case.
|
|
** This feature allows the "queue" of AFL to be captured into a single big
|
|
** file using a command like this:
|
|
**
|
|
** (for i in id:*; do echo '|****<'$i'>****|'; cat $i; done) >~/all-queue.txt
|
|
**
|
|
** (Once again, change the "|" to "/") Then all elements of the AFL queue
|
|
** can be run in a single go (for regression testing, for example) by typing:
|
|
**
|
|
** fuzzershell -f ~/all-queue.txt
|
|
**
|
|
** After running each chunk of SQL, the database connection is closed. The
|
|
** program aborts if the close fails or if there is any unfreed memory after
|
|
** the close.
|
|
**
|
|
** New test cases can be appended to all-queue.txt at any time. If redundant
|
|
** test cases are added, they can be eliminated by running:
|
|
**
|
|
** fuzzershell -f ~/all-queue.txt --unique-cases ~/unique-cases.txt
