Centos 9 Stream build problem "skb_gso_segment" 👀1 purum-pum-pum commented @ordexohh, i too dummy for such things. well, made edit the file /compat-include/net/gso.h for my kernel and yeah. It work. I have build kernel module Thank you for passion and help. I'm waiting new p...
but this might add regressions to existing programs. It turns out our SKB_GSO_DODGY handlers properly set up checksum information that is needed anyway when packets needs to be segmented. By checking again skb_needs_check() after skb_mac_gso_segment(), we should remove these pesky warnings,...

frags 会用在 内核 GSO功能(将TCP 分断从内核协议栈的 TCP 层推迟到 Netdev或L2 层); frags 会用在 内核和网络设备配合的 TSO功能(将TCP 分段从协议栈的TCP 层推迟到硬件实现); frags 会用在 内核和网络设备配合的 Scatter Gather(SG) 功能,SG是指应用层发送小片数据包,然后硬件负责聚合为一笔包。另外...
