October 2025 Monthly Summary for DragonBluep/openwrt: - Delivered a targeted MT7620 kernel stability fix patchset that reduces sporadic kernel issues caused by 26-bit immediate jumps. The change replaces direct jal imm26 calls with an indirect jalr path in critical call sites and adjusts the execution path to avoid problematic PAGE_ALIGN interactions on MT7620. - Specific fix details: indirect invocation via volatile function pointer for get_random_u32_below() and resume_user_mode_work(), plus a simplified setup_arg_pages() flow that omits arch_align_stack() + PAGE_ALIGN() on MT7620. These adjustments preserve behavioral logic while improving robustness. - Commit and PR references: commits 22ccb445e611018ede702e6c0798640353632cce; Link to PR 20553 (Signed-off-by: Mieczyslaw Nalewaj; Signed-off-by: Robert Marko). - Impact: Increased reliability for MT7620-based devices running OpenWrt, reducing kernel oops, hangs, and backtrace corruption; lowers post-release support burden and broadens MT7620 device viability in production environments. - Technologies/skills demonstrated: low-level kernel patching, arch-specific conditional logic, indirect call techniques, rigorous commit hygiene and cross-team collaboration.

August 2025 – OpenWrt stabilization for relay-mode multicast handling.
