2024-02-29Test case for externally concretized variables and constraint fully symbolic ↵Martin Nowack
variables The test case is based on the example provided by Mingyi Liu from the KLEE mailing list.
2024-02-27Small refactorings and reformatting in callExternalFunctionCristian Cadar
2024-02-27This commit fixes the concretization of arguments following an external call ↵Cristian Cadar
with symbolic arguments. It also introduces a new external call policy, where the symbolic inputs are left unconstrained following such a call, useful for certain external calls such as printf.
2024-02-27Two test cases exercising two policies for calling external calls with ↵Cristian Cadar
symbolic arguments. One of them is currently expected to fail.

2024-02-08Assume C compiler's default standard is `-std=gnu17`Martin Nowack
Newer compilers use `-std=gnu17` as the default when compiling C code. Fix all the test cases that violate this behaviour or explicitly request older standards `-std=c89` where necessary.
2024-01-30Add checks to the seed concretization tests about the expected number of queriesCristian Cadar
2024-01-30Added a test for --allow-seed-extensionCristian Cadar
2024-01-30Removed --zero-seed-extension, and merge it with --allow-seed-extension. ↵Cristian Cadar
This reworked logic also fixes a buffer overflow which could be triggered during seed extension.
2024-01-30On a symbolic allocation, retrieve size from a seed, if availableCristian Cadar
2024-01-30Concretize arguments to external function calls using seeds, if available. ↵Cristian Cadar
Added a test case.
2024-01-30Concretize constants using seed values, when available. Added two tests (w/ ↵Cristian Cadar
and w/o seed extension) based on FP concretization.

2024-01-12Feature: implement single memory object resolution for symbolic addresses.Tomasz Kuchta
This feature implements tracking of and resolution of memory objects in the presence of symbolic addresses. For example, an expression like the following: int x; klee_make_symbolic(&x, sizeof(x), "x"); int* tmp = &b.y[x].z; For a concrete array object "y", which is a member of struct "b", a symbolic offset "x" would normally be resolved to any matching memory object - including the ones outside of the object "b". This behaviour is consistent with symbex approach of exploring all execution paths. However, from the point of view of security testing, we would only be interested to know if we are still in-bounds or there is a buffer overflow. The implemented feature creates and tracks (via the GEP instruction) the mapping between the current symbolic offset and the base object it refers to: in our example we are able to tell that the reference should happen within the object "b" (as the array "y" is inside the same memory blob). As a result, we are able to minimize the symbolic exploration to only two paths: one within the bounds of "b", the other with a buffer overflow bug. The feature is turned on via the single-object-resolution command line flag. A new test case was implemented to illustrate how the feature works.

2024-01-12Rename files from PTree to ExecutionTree (and similar)Cristian Cadar
2024-01-12new: persistent ptree (-write-ptree) and klee-ptreeFrank Busse
Introduce three different kinds of process trees: 1. Noop: does nothing (e.g. no allocations for DFS) 2. InMemory: same behaviour as before (e.g. RandomPathSearcher) 3. Persistent: similar to InMemory but writes nodes to ptree.db and tracks information such as branch type, termination type or source location (asm) in nodes. Enabled with -write-ptree ptree.db files can be analysed/plotted with the new "klee-ptree" tool.
2023-09-11Changed use-after-free and double-free tests to expect KDAlloc, plus some ↵Cristian Cadar
small improvements.
2023-07-12Replaced --suppress-external-warnings and --all-external-warnings with ↵Cristian Cadar
--external-call-warnings=none|once-per-function|all. This eliminates the ambiguity when both of the old options were set. Added test for the new option.
2023-06-05test/Feature/StackTraceOutput.c: relative checks, clang-formatJulian Büning
2023-06-05re-enable StackTraceOutput.c testJulian Büning
This test previously had a REQUIRES line with geq-llvm-7.0. Because LLVM version 7.0 is no longer "known" (test/lit.cfg), the required feature is not available and the test is discarded as unsupported by llvm-lit.
2023-05-26Copy stats to test directory when running testsDaniel Schemmel
The sqlite3 databases used for the stats are journalled and potentially must be written to. Therefore, the sqlite3 driver used by `klee-stats` requires write permissions on the database files. By copying the stats files to the test directory, we can now compile and test an out-of-tree build without requiring any write permissions on the source folder at all.
2023-05-26Refactored and fixed the code dealing with the entry point.Cristian Cadar
main() should not be processed if the entry point is a different function. This also fixes an abnormal termination when --entry-point and --libc=uclibc are used together (#1572)
