2024-07-10Fix missed updates of alias table when INTROSPECTION is onTakuya Shimizu
In src/afl-fuzz.c `prev_queued_items` is used to decide whether the alias table should be recreated through the comparison with `afl->queued_items`. https://github.com/AFLplusplus/AFLplusplus/blob/43f462c91b3699b66e4aa1c5703b30f5189b5618/src/afl-fuzz.c#L3103-L3117 However, this variable is also updated to `afl->queued_items` when INTROSPECTION is enabled and the `fuzz_one` appends seeds. https://github.com/AFLplusplus/AFLplusplus/blob/43f462c91b3699b66e4aa1c5703b30f5189b5618/src/afl-fuzz.c#L3135-L3140 Due to the update of `prev_queued_items` when INTROSPECTION is on, alias table may not be recreated when it actually should be. This can lead to potential heap buffer-overflow in `select_next_queue_entry` due to the lack of `afl_realloc` called in `create_alias_table`. This patch fixes this bug by utilizing another variable for the INTROSPECTION part like other variables such as `prev_saved_tmouts`.

2024-07-01Make fallthroughs explicit in afl-fuzz-extras.cRichard Barnes
Using `__attribute__((fallthrough))` makes fallthroughs explicit in a way the compiler can understand. This allows the enablement of `-Wimplicit-fallthrough`.

Optimize bit counting using __builtin_popcount
2024-06-24Optimize bit counting using __builtin_popcountKuan-Wei Chiu
Use the __builtin_popcount intrinsic to optimize the bit counting function if the compiler supports it. This change replaces the manual bit counting algorithm with the more efficient built-in function, which leverages hardware support on compatible processors. This modification ensures that the code remains backward-compatible by falling back to the original implementation when __builtin_popcount is not available.

2024-06-19Collect persistent coverage data and dump it at the end of the runChristian Holler (:decoder)
With CODE_COVERAGE builds, we need to collect the coverage data of each iteration in a persistant buffer that has the same size as the regular trace buffer used for fuzzing. We dump this information at the end of the run and when combined with pointer data and module info, this can be used to calculate code coverage.

Fix signed integer overflow in radamsa
2024-06-14Fix signed integer overflow in radamsaKuan-Wei Chiu
When UBSan was enabled and 'make test' was executed, the following runtime error was observed: libradamsa.c:26055:29: runtime error: left shift of 16777215 by 8 places cannot be represented in type 'int' This issue was caused by a left shift operation on a signed integer. The fix involved changing the integer literal to an unsigned integer by adding a 'U' suffix, ensuring the left shift operation produces the correct value without overflow. Fixes: 8178f4df ("remove radamsa, add radamsa custom mutator")
