`toString` for IR data-flow nodes are now similar to AST data-flow nodes. This should make it easier to use the IR as a drop-in replacement in the future. There are still differences because the IR data flow library takes conversions into account. I did not attempt to align the new nodes we use for field flow. That can come later, when we add field flow to IR data flow. --- .../cpp/ir/dataflow/internal/DataFlowUtil.qll | 18 +++- .../dataflow/dataflow-tests/test_ir.expected | 88 +++++++++---------- .../dataflow/taint-tests/test_ir.expected | 24 ++--- 3 files changed, 74 insertions(+), 56 deletions(-) diff --git a/cpp/ql/src/semmle/code/cpp/ir/dataflow/internal/DataFlowUtil.qll b/cpp/ql/src/semmle/code/cpp/ir/dataflow/internal/DataFlowUtil.qll index 0476ea3c30ab..b5415f2bc656 100644 --- a/cpp/ql/src/semmle/code/cpp/ir/dataflow/internal/DataFlowUtil.qll +++ b/cpp/ql/src/semmle/code/cpp/ir/dataflow/internal/DataFlowUtil.qll @@ -84,7 +84,11 @@ class Node extends TIRDataFlowNode { this.getLocation().hasLocationInfo(filepath, startline, startcolumn, endline, endcolumn) } - string toString() { result = instr.toString() } + string toString() { + // This predicate is overridden in subclasses.

+Testing for signed integer overflow by adding a +value to a variable and then comparing the result to said variable +is not defined by the C or C++ standards. The comparison may +produce an unintended result, or may be deleted by the compiler +entirely. +

+ + +

+Make sure that the comparison in question uses unsigned values. +

+ + +

+In the following example, even though delta has been declared +unsigned short, C/C++ type promotion rules require that its +type is promoted to the larger type used in the addition and comparison, +namely a signed int. As a result, the entire expression is +evaluated using signed values and its value is therefore undefined. +

+ +

+In the next example, a value of type signed int is +getting added to a value ot type unsigned int. Because +the types are of the same size, C/C++ promotion rules dictate that +unsigned int is chosen as the overall type of the addition +operation. The entire expression is evaluated using unsigned +values, which is allowed and defined behavior per the C/C++ standard. +

The entire expression is evaluated using unsigned -values, which is allowed and defined behavior per the C/C++ standard. +In the next example, we have two signed int values that we +wish to add together. Adding them "as-is" opens the possibility of +a signed integer overflow, the results of which are undefined. +By casting one of the operands to unsigned, the entire +expression is evaluated using unsigned +values, which is defined behavior per the C/C++ standard.

MyThing.objects.get(field=userinput)`, and what seems to be a query that wants to match on `thing = MyThing(); thing.field=userinput`. Both are not vulnerable to user-input, due to the build-in escaping by django. The DjangoModelFieldWrite actually matches on `MyThing.field=userinput` and not `thing.field=userinput`. I suspect this to be a mistake.

The predicates that are not cached here, like `CppType::getTypeSize` and `getCanonicalLanguageType`, appear to be cheap. I've tested that this avoids recomputation of the IR type system by running grep -c 'Starting to evaluate predicate CppType::CppType::getIRType_dispred' on the evaluator log for `IRSanity.ql`. It drops from 4 to 1.

    +When checking for out-of-range pointer values, one might write tests like +p + a < p and check if the value "wraps around". +Such a test is wrong in that it relies on the overflow of p + a, +which is undefined behavior. In fact, many optimizing compilers will remove +p + a < p altogether and replace it with the value 0 +(false). Conversely, should p + a not overflow, +the programmer may erroneously assume that the memory location p + a +is accessible to the program, even though it may be inaccessible (protected by +the operating system) or nonexistent. +

    +     + +

    +When checking for an out-of-range pointer, compare the pointer +value p against a known value p_max representing +the highest allowable memory address. Ideally, p_max should +point just past the end of a data structure, such as an array or a vector. +For lower-level work, it should point at the highest address in the program +heap. It is also important that p + a points at a valid object +and that a is small enough so that the expression p + a +does not itself overflow. +

    +     + +

    +In the first example, a constant value is being added to a pointer and +then tested for "wrap around". Should the test fail, the developer +might assume that memory location ptr + 0x12345678 is a +valid one for the program to use, even though it may be either +inaccessible (protected from the current process by the operating +system) or nonexistent. Furthermore, it may be impossible to tell when +the test succeeds, since pointer overflow has undefined behavior. +

    + +

    +The next example shows how to properly check for an out-of-range pointer. +In order to do so, we need to obtain the value ptr_end +representing the highest allowable memory address. In this case, +the address lies just beyond the end of an array. +

At first glance, QL, which can only work with atomic values, does not seem to be well suited for working with this kind of data. However, ultimately all that we require of the nodes in an AST is that they have an identity. The relationships among nodes, usually implemented by reference-valued object fields in other languages, can just as well (and arguably more naturally) be represented as relations over nodes. Attaching data (such as strings or numbers) to nodes can also be represented with relations over nodes and primitive values. All we need is a way for relations to reference nodes. This is achieved in QL (as in other database languages) by means of *entity values* (or entities, for short), which are opaque atomic values, implemented as integers under the hood. - It is the job of the extractor to create entity values for all AST nodes and populate database relations that encode the relationship between AST nodes and any values associated with them.

Entity values belong to *entity types*, whose name starts with “@” to set them apart from primitive types and classes. The interface between entity types and extensional relations on the one hand and QL predicates and classes on the other hand is provided by the *database schema*, which defines the available entity types and the schema of each extensional relation, that is, how many columns the relation has, and which entity type or primitive type the values in each column come from. QL programs can refer to entity types and extensional relations just as they would refer to QL classes and predicates, with the restriction that entity types cannot be directly selected in a ``select`` clause, since they do not have a well-defined string representation. diff --git a/docs/language/ql-training/slide-snippets/info.rst b/docs/language/ql-training/slide-snippets/info.rst deleted file mode 100644 index 583a456207bb..000000000000 --- a/docs/language/ql-training/slide-snippets/info.rst +++ /dev/null @@ -1,33 +0,0 @@ -Information -=========== - -To try the examples in this presentation we recommend you download `QL for Eclipse `__. - -**QL language resources** - -- If you are new to QL, try the QL language tutorials at `Learning CodeQL `__. -- To learn more about the main features of QL, try looking at the `QL language handbook `__. -- For further information about writing queries in QL, see `Writing QL queries `__. - -**QL queries** - -The QL queries included in the latest Semmle release are open source.

Previously, we didn't track string literals as known memory locations at all, so they all just got marked as `UnknownMemoryLocation`, just like an aribtrary read from a random pointer. This led to some confusing def-use chains, where it would look like the contents of a string literal were being written to by the side effect of an earlier function call, which of course is impossible. To fix this, I've made two changes. First, each string literal is now given a corresponding `IRVariable` (specifically `IRStringLiteral`), since a string literal behaves more or less as a read-only global variable. Second, the `IRVariable` for each string literal is now marked `isReadOnly()`, which the alias analysis uses to determine that an arbitrary write to aliased memory will not overwrite the contents of a string literal. I originally planned to treat all string literals with the same value as being the same memory location, since this is the usual behavior of modern compilers. However, this made implementing `IRVariable.getAST()` tricky for string literals, so I left them unpooled. --- .../implementation/aliased_ssa/IRVariable.qll | 57 ++++++++++++++----- .../aliased_ssa/Instruction.qll | 10 ++-- .../aliased_ssa/internal/AliasAnalysis.qll | 4 ++ .../aliased_ssa/internal/AliasedSSA.qll | 12 ++-- .../aliased_ssa/internal/SSAConstruction.qll | 5 -- .../implementation/internal/TIRVariable.qll | 6 ++ .../cpp/ir/implementation/raw/IRVariable.qll | 57 ++++++++++++++----- .../cpp/ir/implementation/raw/Instruction.qll | 10 ++-- .../raw/internal/IRConstruction.qll | 23 +++++--- .../unaliased_ssa/IRVariable.qll | 57 ++++++++++++++----- .../unaliased_ssa/Instruction.qll | 10 ++-- .../unaliased_ssa/internal/AliasAnalysis.qll | 4 ++ .../internal/SSAConstruction.qll | 5 -- .../ir/ssa/aliased_ssa_ir.expected | 26 +++++++++ cpp/ql/test/library-tests/ir/ssa/ssa.cpp | 8 +++ .../ir/ssa/unaliased_ssa_ir.expected | 25 ++++++++ .../implementation/internal/TIRVariable.qll | 6 ++ .../ir/implementation/raw/IRVariable.qll | 57 ++++++++++++++----- .../ir/implementation/raw/Instruction.qll | 10 ++-- .../raw/internal/IRConstruction.qll | 25 +++++--- .../unaliased_ssa/IRVariable.qll | 57 ++++++++++++++----- .../unaliased_ssa/Instruction.qll | 10 ++-- .../internal/SSAConstruction.qll | 5 -- 23 files changed, 359 insertions(+), 130 deletions(-) diff --git a/cpp/ql/src/semmle/code/cpp/ir/implementation/aliased_ssa/IRVariable.qll b/cpp/ql/src/semmle/code/cpp/ir/implementation/aliased_ssa/IRVariable.qll index 1a607f82c29f..e10e266b2ab3 100644 --- a/cpp/ql/src/semmle/code/cpp/ir/implementation/aliased_ssa/IRVariable.qll +++ b/cpp/ql/src/semmle/code/cpp/ir/implementation/aliased_ssa/IRVariable.qll @@ -22,6 +22,12 @@ abstract class IRVariable extends TIRVariable { abstract string toString(); + /** + * Holds if this variable's value cannot be changed within a function.
