This test case implements a singleton struct without synchronization that can lead to two threads receiving separate instances of the singleton struct resulting in a deadlocked state. It takes a control integer, the names of two control files, and another integer as input. The control integer and...

This test case implements a singleton struct without synchronization that can lead to two threads receiving separate instances of the singleton struct resulting in a deadlocked state. It takes a control integer, the names of two control files, and another integer as input. The control integer and...

This test case takes the name of an externally accessible file as input, and treats the file as a global mutex lock. The test case will attempt to 'grab' the mutex lock by checking for the files existence, and creating it if it doesn't exist. The creation of the file is treated as grabbing the lo...

This test case implements two threads that do not use synchronization while accessing a shared resource. The test case takes a control integer, the names of two control files, and an input string. The control integer and the two control files are used for timing within the test case to ensure tha...

It takes a control integer, the names of two control files, and another integer as input. The control integer and...

This test case implements a time of check time of use vulnerability that allows a DOS due to the input file being deleted before opening. The test case takes in a control file and an input file. The input file is checked to see if it is in the current working directory and exists. If both of thes...

C programs have two main options for mutual exclusion of a shared resource in a concurrent setting: the mutex lock and the semaphore. Mutex locks exist in two states, locked and unlocked. However a semaphore, more specifically a counting semaphore, can be used to keep track of an arbitrary number...

This test case implements two threads that each use a separate mutex lock object while accessing a shared resource. The test case takes a control integer, the names of two control files, and an input string. The control integer and the two control files are used for timing within the test case to...

The control integer and the two control files are used for timing within the test case to ensure tha...

This test case implements a non-reentrant function that uses a static integer to iterate through a string setting each character to null. The test case takes a control integer and an input string. The control integer is used for timing within the test case to ensure that we hit either a good or b...

This test case implements a double checked lock around the initialization of a shared struct in an attempt to be efficient. The test case takes a control integer, the names of two control files, and an input string. The control integer and the two control files are used for timing within the test...

This test case implements a single signal handler that is associated with two signals. The test case takes the names of two control files and an input string. The control files are used for timing within the test case to ensure that the test case follows an exploiting or benign execution path, an...

This test case implements two threads that each use a separate mutex lock object while accessing a shared resource. The test case takes a control integer, the names of two control files, and an input string. The control integer and the two control files are used for timing within the test case to...

This test case implements two thread that both lock two shared mutex locks such that if the timing works out, they will cause each other to deadlock. The test case takes a control integer, the names of two control files, and an input string. The control integer and the two control files are used ...

The input file is checked to see if it is in the current working directory and exists. If both of thes...

This test case implements an asynchronous unsafe signal handler that access a string without properly null checking the pointer. The test case takes the name of a control file and an input string. The control file is used for timing within the test case to ensure that the test case follows an exp...

This test case implements two thread that both lock two shared mutex locks such that if the timing works out, they will cause each other to deadlock. The test case takes a control integer, the names of two control files, and an input string. The control integer and the two control files are used ...

This test case implements two threads that lock a counting semaphore multiple times, causing a deadlock if the lock is locked more times that it is unlocked. The test case takes a string as input and if the input string contains spaces spawns two threads, the first of which locks a semaphore twic...
