Cppcheck reports at the affected calls:
invalidPrintfArgType_sint: %d requires 'int' but the argument type
is 'unsigned int'.
invalidPrintfArgType_sint: %zd requires 'ssize_t' but the argument
type is 'size_t {aka unsigned long}'.
invalidPrintfArgType_uint: %llx requires 'unsigned long long' but
the argument type is 'unsigned long'.
invalidPrintfArgType_uint: %u requires 'unsigned int' but the
argument type is 'signed int'.
invalidScanfArgType_int: %lld requires 'long long *' but the
argument type is 'unsigned long long *'.
Use unsigned formats for command states, event IDs, handles and sizes.
Cast the u64 disk ID for %llx on both 32-bit and 64-bit builds. Preserve
unsigned export-link naming through an explicit counter conversion. Use
%llu for the unsigned virtual-disk size destination; retain the byte/MiB
shifts and overflow check.
At five DLM lock-name calls, explicitly convert node IDs to int for the
existing %d formats. Switching them to %u would change high-bit node
IDs' lock identities and break matching with older peers. Preserve that
signed spelling and leave membership and node-ID storage unchanged.
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.
Documentation
- Building and installing SCST.
- Build options: Clang, cross-compilation, and kernel module signing.
- Configuration and administration: targets, devices,
LUNs, and
/etc/scst.conf. - Core and device handlers: operating modes, module parameters, and sysfs configuration.
- Target drivers: iSCSI, iSER, QLogic Fibre Channel, SRP, FCoE, and local loopback.
- Performance tuning.
- Clustered persistent reservations: synchronization through DLM.
- T10 protection information: data integrity modes and configuration.
- Developer references: architecture and userspace handler interface (SGML sources), and sysfs interface rules.
- Contributing: code style, commit conventions, local checks, and guides to KUnit and component testing.
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.
