What I work on:

Project Contribution Result
Linux kernel — ath11k Wi-Fi driver Root-caused a firmware crash that took the whole SoC down on AHB hardware: interrupts stayed enabled while the data path was torn down mid-crash Applied to ath-next — a7ab5c8, f7a74e1
Linux kernel — ath11k + mac80211 airtime ath11k advertised neither AQL nor airtime fairness, so every mac80211 queue knob was disconnected and the entire queue sat in the driver's rings. Series enables both and moves TXQ scheduling into the driver 9-patch ath11k series + 3 mac80211 patches in review · lore ↗
Linux kernel — netfilter flowtable Offload gaps found while driving switch hardware from the flowtable: VLAN match never advertised in used_keys, no priority carried into the offload, one-directional TCP flows never offloaded 4 series with selftests on netfilter-devel · lore ↗
OpenWrt — Qualcomm IPQ807x drivers Kernel 6.18 target uplift, 30+ defects fixed across the switch, PCS and ethernet drivers, and RX/TX checksum, scatter-gather, TSO and RSS hash offloads on the ethernet engine 26 PRs merged into the OpenWrt project · all PRs ↗
OpenWrt — PPE hardware flow offload Host-driven offload for the IPQ807x packet processing engine: routing, NAT, PPPoE, port shaping, QoS classification and queue management, driven from nftables and tc with no vendor SDK 47 commits, ~9.6k lines, in review · PR #24806 ↗
OpenWrt — NSS offload distribution The only NSS build that keeps OpenWrt's upstream ethernet and DSA drivers instead of replacing them with the vendor stack ~40× lower CPU load — 99.7 % idle routing NAT + PPPoE at line rate, 16 ms RTT under full SQM load · openwrt-nss-edma ↗
Security — OpenWrt 15 reports across five repositories: pre-auth HTTP request smuggling, out-of-bounds write via ubus params type confusion, unauthenticated memory exhaustion, ACL bypasses reaching a root shell 4 advisories published, CVE assignment in progress · advisories ↗
Security — Qualcomm NSS offload stack 14 defects reported to Qualcomm Product Security against the shipping vendor stack Acknowledged by Qualcomm, CVE assessment in progress; fixes shipping in nss-packages ↗
FFmpeg / AMD AMF Fixed AMF hardware-filter initialization for D3D11VA/DXVA2 input, then the sr1-1 green frame on YUV input and ten further pre-existing bugs across the AMF filters; reported SDK defects that AMD fixed and that added the VQ Enhancer filter to FFmpeg Merged · commit ↗ · 11-bug series in review · PR #23351 ↗
