Instead of modifying in_buf directly, we write the update out to the disk when trimming is complete, and then the caller is responsible for refreshing the in-memory buffer from the file. This is still a bit sketchy because it does need to modify q->len in order to notify the upper layers that something changed, and it could end up telling upper layer code that the q->len is *bigger* than the buffer (q->testcase_buf) that contains it, which is asking for trouble down the line somewhere... * Fix an unlikely situation Put back some `unlikely()` calls that were in the e9d2f72382cab75832721d859c3e731da071435d commit that was reverted. --- include/afl-fuzz.h | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'include') diff --git a/include/afl-fuzz.h b/include/afl-fuzz.h index 040d7ae9..f201782a 100644 --- a/include/afl-fuzz.h +++ b/include/afl-fuzz.h @@ -1003,7 +1003,7 @@ void read_afl_environment(afl_state_t *, char **); /* Custom mutators */ void setup_custom_mutators(afl_state_t *); void destroy_custom_mutators(afl_state_t *); -u8 trim_case_custom(afl_state_t *, struct queue_entry *q, u8 **in_buf, +u8 trim_case_custom(afl_state_t *, struct queue_entry *q, u8 *in_buf, struct custom_mutator *mutator); /* Python */ @@ -1093,7 +1093,7 @@ fsrv_run_result_t fuzz_run_target(afl_state_t *, afl_forkserver_t *fsrv, u32); void write_to_testcase(afl_state_t *, void *, u32); u8 calibrate_case(afl_state_t *, struct queue_entry *, u8 *, u32, u8); void sync_fuzzers(afl_state_t *); -u8 trim_case(afl_state_t *, struct queue_entry *, u8 **); +u8 trim_case(afl_state_t *, struct queue_entry *, u8 *); u8 common_fuzz_stuff(afl_state_t *, u8 *, u32); /* Fuzz one */ -- cgit v1.2.3 From 069e61dfc67050154b649ba286552b563b27e9ba Mon Sep 17 00:00:00 2001 From: "Roman M.
