[2025-06-30]: Update monthly version OpenCloudOS-9.4-20250616.0. Typically includes: fixed rpm packages for recently discovered bugs, security fixes, and optimization or upgrades for some rpm packages. Special note the following updates:
- ** kernel      ** has been upgraded to 6.6.88-32, merging upstream Linux 6.6.81 through 6.6.88, and introducing support for Hygon 7h/10h and family 18h model 8h processors, DF PMU modules, and enhanced CPU info reporting for AmpereOne and HiSilicon platforms. New drivers include sxe/sxevf, mucse, Montage Mont-TSSE (v1.1.2), and commercial-grade Intel (i40e, ice, iavf, ixgbe) and Loongson PCI bridge/crypto modules. Features like fuse passthrough and persistent block device enumeration for modular storage drivers are added. Critical fixes address net_cls output, disk device ordering, Mellanox/ICE driver issues, Loongson VM boot failures, and multiple CVEs.
- ** glibc       ** has been updated to 2.38-32, fixing a performance regression in posix_memalign() and addressing CVE-2025-4802 by restricting LD_LIBRARY_PATH and debug environment variables for setuid static binaries. It also introduces backported optimizations for Hygon and AMD processors, including improved memset performance via non-temporal storage and enhanced architecture/cache support.  


[2025-09-05]: Update monthly version OpenCloudOS-9.4-20250819.0. Typically includes: fixed rpm packages for recently discovered bugs, security fixes, and optimization or upgrades for some rpm packages. Special note the following updates:
- ** kernel      ** has been updated to 6.6.98-38, merging upstream Linux 6.6.89–6.6.98 and introducing platform and virtualization enhancements, including user-space page encryption on Hygon, PSWIOTLB on Phytium for DMA performance, NUMA-aware spinlocks, and support for uncached IO. Driver support is expanded with Huawei hinic3 NIC, Loongson 2K3000 GMAC/PWM, Wangxun 1G–40G, Broadcom RAID, and SmartPQI storage devices. Additional updates include support for SEV-SNP virtualization, NVMe interrupt coalescing, ARM64 Android containers, huge text mappings, and /proc/config.gz modular export. This release also incorporates SCX scheduler updates from Linux 6.12 and improves reliability with mutex-aware hungtask tracking, code path hugepage support, PCP list auto-tuning, and multiple CVE fixes.
- ** glibc       ** has been updated to 2.38-36, fixing CVE-2025-8058 and multiple bugs including a double-free in regcomp, condition variable compatibility with older versions, and a race in pthreads causing lost wakeups. Also includes a fix to sem_open for BZ#30789 and a malloc regression fix affecting core counting.
- ** systemd     ** has been updated to 255-14.oc9.ap.4, fixing a crash in journald during concurrent logrotate operations.
- ** net-tools   ** has been updated to 2.10-8, fixing a regression in ifconfig where RX/TX packet counts were always zero. This issue was introduced by the upstream patch for CVE-2025-46836 applied in version 2.10-7.
