Stable Release, 4th of May 2026

uname -a shows omnios-r151058-516f7694c9

r151058 release repository: https://pkg.omnios.org/r151058/core

Upgrade Notes

Upgrades are supported from the r151054 and r151056 releases only. If upgrading from an earlier version, upgrade in stages, referring to the table at https://omnios.org/upgrade.

New features since r151056

System Features

  • IPv6 networking has gained a fast path implementation, similar to that already present for IPv4. This bypasses the data link services (DLS) layer for suitable traffic and improves throughput.

  • The kernel MAC framework's softring polling code now correctly enforces its configured byte limit, and various accounting issues with fanout statistics and dual-stack TCP softrings have been corrected.

  • Disabling hardware checksum offload via dohwcksum now also disables Large Segment Offload (LSO), preventing transmission failures on certain interfaces.

  • The Intel IOMMU code is now more informative when it encounters unknown remapping structures, and the immu-dmar-print debug option works again.

Commands and Command Options

  • The snoop(8) utility has gained a new direction flag, along with corresponding incoming- and outgoing-only DLPI capture modes in the kernel. This makes it possible to reliably capture only inbound or only outbound traffic on an interface.

  • smbios(8) now displays an endian-corrected form of the system UUID alongside the raw value, decodes Type 43 (TPM) records and decodes management device and component records.

  • pcieadm has gained the ability to decode Data Object Exchange (DOE) capabilities, decode Virtio vendor-specific capabilities, display PCI configuration space at arbitrary offsets and manipulate device BARs.

  • nvmeadm(8) can now run vendor-specific commands, list namespace format information and supports several Sandisk vendor-specific commands and log pages, including telemetry log retrieval. The identify controller and features support has been updated for the NVMe 2.1 specification.

  • diskinfo(8) now correctly displays location information for NVMe devices.

  • du(1) handles large offsets correctly and the -A flag continues to report block counts rather than bytes.

  • pmap(1) now supports the -A option when inspecting core files.

  • cp(1) and mv(1) have gained a new -n option (do not overwrite an existing file), and ln(1) has gained -i (interactive prompt before overwrite). The -i mode now also prompts before overwriting non-regular files.

Libraries and Library Functions

  • AES-GMAC sign and verify support has been added to PKCS#11, and the underlying kernel AES implementation now supports GMAC input through the standard mac interfaces.

  • atan2(0.0, -0.0) no longer sets errno unexpectedly.

Networking

  • SMB 3.1.1 supports GMAC signing, with associated capability negotiation. This generally offers better performance than CMAC on modern hardware. The supporting cryptographic infrastructure has been reworked to use unified MAC functions and single-shot scatter/gather signing interfaces.

  • SMB Active Directory join has been improved: the server now avoids using kadmin/setpw kpasswd when not required, falls back gracefully if krb5.conf is not configured and recovers cleanly from a domain re-join failure that previously left smbd in an inconsistent state.

  • SMB2 asynchronous responses now more closely match the behaviour of Windows servers.

  • The C$ administrative share now requires administrative privileges.

  • Multiple fixes to the kernel NLM (Network Lock Manager) implementation resolve memory leaks, NULL pointer dereferences, port leaks that could cause NFS services to become unavailable, and a regression with macOS 14 servers.

ZFS

  • zfs change-key can now atomically update user properties at the same time as it changes an encryption key, by way of new -o user:prop=value arguments. This eliminates a window in which the property and key could become out of sync.

  • A bug in the ZFS Intent Log replay path could cause transactions to be replayed out of order following an unexpected system restart, potentially leading to data corruption. This has been fixed.

  • The SMB server and ZFS getattr paths now avoid many redundant idmap lookups, improving performance for SMB workloads on ZFS.

Bhyve

  • Bhyve now supports transitional virtio devices, presenting both the legacy and modern (1.0+) virtio interfaces simultaneously. This improves guest compatibility, particularly for guests booted via modern UEFI firmware.

  • The viona virtual NIC has gained virtio-net multi-queue support, and now supports asymmetric receive and transmit queue sizes. Bhyve advertises link speed and duplex to guests, and the corresponding illumos vioif driver consumes that information.

  • The bhyve virtio-scsi device is now enabled, supports multiple backends, multiple targets and task management functions, and offers a USCSI backend.

  • The kernel vioscsi driver has received numerous correctness fixes.

  • Virtio devices in bhyve no longer expose unsupported MSI capabilities; only legacy and MSI-X interrupts are advertised.

  • Various smaller bhyve improvements: better diagnostics for non-bootable VMs, the umouse device makes fewer assumptions about the request format, and the pci-uart device sets the correct subclass.

  • Setting the bootnext attribute in a bhyve-branded zone no longer prevents the zone from booting.

LX zones

  • The emulated /proc/self/coredump_filter file is now provided.

Hardware Support

  • A new I2C and SMBus framework has been added to illumos, providing the i2cnex kernel driver, libi2c.so.1 userland library and the i2cadm(8) administration tool.

  • A new kernel GPIO framework provides the kgpio driver, libxpio.so.1 library and the gpioadm(8) command, along with support for AMD GPIO controller attributes.

  • New drivers built on these two frameworks include:

    • Intel SMBus Controllers (pchsmbus(4D) and ismt(4D))
    • LTC4305/6 I2C Mux and GPIO
    • PCA954x family I2C multiplexers
    • PCA953x family I2C GPIO expanders
    • AT24C family I2C EEPROMs
    • DDR4 and DDR5 I2C SPD EEPROMs
    • TS511x DDR5 temperature sensors (integrated with ksensor)
    • LM75 family I2C temperature sensors
    • TMP43x family I2C temperature sensors

  • A new EEPROM driver framework provides a standardised character device interface for EEPROM-class devices.

  • Support has been added for the Intel E610 family of network interfaces via the ixgbe driver.

  • The ena driver now attaches correctly on AWS Nitro v5/v6 instance types (such as the m8a family).

  • The libsff values have been updated to reflect the latest SFF transceiver specifications.

  • Support has been added for AMD Phoenix 2 processors in amdzen(4D), and for Alder Lake-N SMBus device IDs.

  • On Zen5 processors with sufficiently new microcode, the previously disabled RDSEED instruction is now re-enabled.

  • The asy(4D) serial driver has gained better debugging facilities and is no longer overly chatty when ports are missing.

Storage

  • scsi_vhci now supports configuration of the load-balancing policy for individual logical units via mpathadm(8), rather than only globally.

  • NVMe devices used as a system boot device no longer end up with only a single I/O queue, and are no longer reported as failed by ZFS when they return a queue-saturation error.

Modular Debugger

  • mdb has gained a new dcmd (::pcie_fatal_errors) for inspecting the source of a PCIe fatal error, to aid in diagnosing AER-reported failures.

Boot Loader

  • On UEFI, the loader now produces stack traces on panics and faults, no longer complains about missing block device handles, and several bugs in UEFI and the TSS setup have been resolved.

  • IP fragment reassembly in the loader has been corrected.

  • Systems which map the linear framebuffer above 32 bits no longer cause dboot to overwrite arbitrary memory because the BSS is now correctly zeroed.

Cryptography

  • New tests have been added for HMAC-SHA2 and various PKCS CCM/GCM cases. In the process, a panic in the kernel crypto driver and a cryptoadm failure to retrieve the mechanism list were fixed. Crypto tests can also now be run as a non-root user.

Installer

  • It was previously not possible to configure the serial console configuration during installation for anything other than ttya; this has been corrected.

Developer Features

  • OmniOS userland is now built with gcc 15 by default. The previous gcc 14 compiler remains available, and a new developer/gcc15 package has been added. A large number of packages have received minor build fixes for compatibility with the newer compiler.

  • The kernel runtime linker is now able to load larger kernel modules.

  • The cw compiler wrapper has gained a --time option to report compiler execution time.

  • pcre2 is now built with JIT support.

Deprecated features

  • The grub boot loader is deprecated and was removed in the r151048 release. If you have not yet migrated to the new boot loader, and would like assistance, please get in touch.

  • OpenSSL 1.0.x and 1.1.1 are deprecated and reached end-of-support at the end of 2019 and in September 2023 respectively. OmniOS has transitioned to OpenSSL 3 and still ships older versions for backwards compatibility, but these are maintained solely on a best-efforts basis. If possible, recompile software to use OpenSSL 3.

  • Python 2 is now end-of-life and will not receive any further updates. The python-27 package is still available for backwards compatibility but will be maintained only on a best-efforts basis.

  • OpenSSH in OmniOS no longer provides support for GSSAPI key exchange. This was removed in release r151038.
