ssh_packet_set_data(9)

💖 ssh_packet_set_data(9) — Kernel API Manual 💖

okay bestie, this is the Kernel API Manual page for ssh_packet_set_data(9), and it’s honestly pretty iconic for such a tiny function 🎀

✨ NAME ✨

ssh_packet_set_data — set raw message data of packet.

🌸 SYNOPSIS 🌸

void ssh_packet_set_data (struct ssh_packet *p , u8 *ptr , size_t len );

🎀 ARGUMENTS 🎀

• p — the packet for which the message data should be set.
• ptr — pointer to the memory holding the message data.
• len — length of the message data.

💅 DESCRIPTION 💅

okay so this function sets the raw message data buffer of the packet to the memory you provide. The memory is not copied — nope, not even a little. Instead, the caller is responsible for management of that memory (i.e. allocation and deallocation), bestie. You have to make sure the provided memory is valid and contains a valid SSH message, starting from the time of submission of the packet until the release callback has been called. During that whole window, the memory may not be altered in any way. no cap. 💀
