Provide kunit-build for all test-owning modules and their dependencies, kunit-run for existing artifacts, and kunit-test for a sequential build and run even under make -j. Allow root builds and run every command with the caller's privileges. Require root for module execution. Map KUNIT_TEST and KUNIT_LOG to private Kbuild switches. Default KUNIT_LABEL to ALL and use KUNIT_ARGS for other runner options and module paths. Resolve artifacts from explicit arguments, configuration or the recorded build, preserving spaces. Group and align the Makefile help for component tests, KUnit and ordinary build targets. Read label-to-suite mappings and dependency order from module metadata, without a separate Python owner registry. Reject dependency cycles and missing SCST core artifacts. Load external kernel dependencies with modprobe before preparing KUnit; keep shared system modules loaded. Load only selected SCST owners and their dependencies from the supplied build and trigger suites through native KUnit debugfs. Support built-in and modular KUnit with autorun disabled. Load modular KUnit with known parameters when absent and release it after SCST cleanup or a clean initial load failure. Reuse an existing instance only after validating its effective parameters in sysfs; reject invalid or unreadable values without changing the module. Never unload preloaded KUnit. Check global filters before loading SCST. Capture fresh kernel records and parse suites with the upstream KTAP parser. Preserve logs and skip reasons, associating first-parameter diagnostics with their case without changing plans or results. Stop module operations on incomplete evidence, diagnostics or retained fixtures. Continue after ordinary assertion failures. Finish capturing output after command exit. Distinguish suites not started from missing results, and count each Oops as one event. Print concise errors and colored terminal statuses as suites finish. Group failure details after progress. Normalize each assertion block independently of printk messages while retaining value indentation. Follow with explicit stop reasons and a compact SCST build summary. Reserve module headings, author, license, source checksums, vermagic and other modules for verbose output. Keep full case logs, module metadata and kernel diagnostics in plain-text and JSON reports. Cover build ordering, selection, kernel setup, dependency preparation, runner lifecycle and reporting with mocked operations. Document VM setup, build, execution and extension in the KUnit guide. Add kunit-clean for test-owning component builds. Invalidate the recorded module list and clear tooling caches on ordinary and component clean paths too, including failed cleanup. Preserve reports and user settings. Check all tooling, kunit-build and cleanup in one CI job. Pin the Fedora container by digest and fetch a fixed kernel-devel package from Koji with a SHA-256 check, independently of the regression matrix. Save build evidence without building a kernel or loading modules.
Overview
This is the source code repository of the SCST project. SCST is a collection of Linux kernel drivers that implement SCSI target functionality. The SCST project includes:
- The SCST core in the scst/ subdirectory.
- A tool for loading, saving and modifying the SCST configuration in directory scstadmin/.
- Several SCSI target drivers in the directories iscsi-scst/, qla2x00t-32gbit/, qla2x00t/, srpt/, scst_local/ and fcst/.
- User space programs in the usr/ subdirectory, e.g. fileio_tgt.
- Various documentation in the doc/ subdirectory.
Instructions for building and installing SCST are available in the INSTALL.md file.
Current master packages
Prebuilt x86_64 packages from the latest successfully published master
build are available in the rolling
master-rpm prerelease.
These are development snapshots, not SCST releases.
The snapshot contains RPM bundles for selected Rocky Linux and Oracle Linux
UEK kernels. It also contains Ubuntu LTS bundles with scst-dkms, scstadmin
and iscsi-scst binary packages and their Debian source package files. Exact
distribution releases and RPM kernel versions are included in the asset names.
Every .tar.gz bundle has a matching .sha256 file. The complete snapshot is
replaced after each successful package workflow for the current master
commit.
QLogic target driver
Two QLogic target drivers are included in the SCST project.
The default driver is located in the qla2x00t-32gbit directory. It is the newer one.
May anyone wish to switch back to the older driver that only supported up to
16 Gb/s adapters, it is located in qla2x00t directory. To make use of the
older driver build scst with environment variable QLA_32GBIT=no set.
