STRUCT SSH_PACKET_OPS(9)

🦋 NAME 🦋

struct ssh_packet_ops — like, the callback operations for an SSH packet, bestie. It's from the Kernel API Manual, iykyk 💅

✨ SYNOPSIS ✨

struct ssh_packet_ops {
    void (*release)(struct ssh_packet *p);
    void (*complete)(struct ssh_packet *p, int status);
 };

🎀 Members 🎀

• release — okay so this one gets called the moment the packet's reference count hits zero, no cap. And like, you literally have to be able to count on this callback to make sure the packet has fully left the transport system(s). It's giving "last one out, turn off the lights" energy 🕯️
• complete — this one fires when the packet is completed, whether that's a slay (success) or an oof (failure). If it's a failure, the reason is indicated by the value of the status code argument they hand you. That status value will be zero in the success case ✨ Now, huge caveat bestie: a call to this callback does not guarantee the packet is no longer in use by the transport system. Like, it might still be out there living its main character life. Do not assume. 🙈
