Webgenerating a custom Seccomp profile. Tracing Solutions Nowadays there are several container tracing solutions, most of them work on a high level with metrics such as: central processing unit (CPU) usage, memory utilization, network input and output among others. These solutions range from the Docker engine itself, cAdvisor [11] which creates a hook Websyscall () is a small library function that invokes the system call whose assembly language interface has the specified number with the specified arguments. Employing syscall () is useful, for example, when invoking a system call that has no wrapper function in the C library. syscall () saves CPU registers before making the system call ...

Web6 Nov 2024 · One way to limit the system calls available to a process is by using seccomp, short for Secure Computing Mode. Seccomp is a mechanism in the Linux kernel which allows a process to make a one-way transition to a secure mode where only exit(), sigreturn(), read(), and write() on file descriptors already opened can be made. Web23 Jul 2024 · The obvious candidate to look at is seccomp. Short for “secure computing” it provides a way of restricting the syscalls of a task either by allowing only a subset of the syscalls the kernel supports or by denying a set of syscalls it thinks would be unsafe for the task in question.
WebAppArmor is a Mandatory Access Control (MAC) system, implemented upon the Linux Security Modules (LSM). AppArmor, like most other LSMs, supplements rather than replaces the default Discretionary Access Control (DAC). As such it is impossible to grant a process more privileges than it had in the first place. Web- It builds now on 32 bit and without strict RWX * Static call enabling is no longer configurable * Refactored arch_static_call_transform to minimise casting * Made the KUnit tests more robust (previously they changed non-volatile registers in the init hook, but that's incorrect because it returns to the KUnit framework before the test case is called).
