configfs locking

About this tag
Configfs locking refers to synchronization mechanisms within the Linux kernel's configfs filesystem, which is used for managing kernel objects like SCSI targets. A notable issue, CVE-2026-23292, involved a recursive locking bug in __configfs_open_file() where target_core_item_dbroot_store() could re-enter configfs while holding a semaphore, risking deadlock. The fix replaced filp_open() with kern_path() to avoid this self-referential lock acquisition. Discussions on WindowsForum.com cover such kernel-level locking problems, their impact on system stability, and the patches applied to resolve them. These topics are relevant for developers and system administrators working with Linux kernel internals and storage subsystems.

    CVE-2026-23292: Fixing Recursive Locking in Linux configfs SCSI Target

    The Linux kernel’s CVE-2026-23292 is a classic example of a bug that looks narrow on paper but matters because it sits in the kernel’s core synchronization machinery. The issue was assigned after maintainers fixed a recursive locking problem in __configfs_open_file(), where...
