Detecting Kernel Refcount Bugs with Two-Dimensional Consistency Checking
2021
USENIX Security Symposium
Preserved Fulltext
In the Linux kernel, reference counting (refcount) has become a default mechanism that manages resource objects. ...
By checking if callers consistently use a refcount function, CID detects deviating cases as potential bugs, and by checking how a caller uses a refcount function, CID infers the condition-aware rules for ...
RID [29] proposes inconsistent path pair (abbreviated as IPP) checking to detect refcount bugs. ...

Critical bugs occur when these operations are performed (1) in an incorrect order, (2) redundantly, or (3) inadequately. We refer to such bugs as Disordered Error Handling (DiEH). ...
With HERO, we found 239 DiEH bugs in the Linux kernel, the FreeBSD kernel, and OpenSSL, which can cause security and reliability issues. ...
The authors also thank Peng Le for helping implement function pairing. This research was supported in part by the NSF awards CNS-1815621 and CNS-1931208. ...

Our contributions in this paper are threefold: • uncovering bugs and inconsistencies in common PDF readers (bugs were reported and are currently under review by software editors [6] , [7] ); • proposing ...

Correctness of a program with respect to concurrency is often hard to achieve, but easy to specify: the concurrent program should produce the same results as a sequential reference version. ...
Using techniques from bounded software model checking, we transform the program into an SMT formula that becomes unsatisfiable when we add correct atomic sections. ...
To model such context switches, we split statements with more than one reference to a global variable. ...

Through an empirical study of the version control system of 265 OpenStack projects, we find that infrastructure files are large and churn frequently, which could indicate a potential of introducing bugs ...
The amount of work involved with such maintenance, as well as the size and complexity of infrastructure specification files, have not yet been studied empirically. ...
Motivation: Based on the preliminary questions, we find that infrastructure files are large and see a lot of churn, which means that they might be bug prone. ...
