iscsi_tcp_r...gment_is_hdr(9)

📦 version 7.3.1, in nixpkgs unstable

💅 iscsi_tcp_recv_segment_is_hdr(9) 💅

okay so this is a page from the Kernel API Manual, section 9 — yes bestie, we're in the deep kernel lore now, and honestly? it's giving "I read the source for fun" energy and I'm obsessed 🧚✨

🌸 NAME 🌸

iscsi_tcp_recv_segment_is_hdr — the little guy that tests if we are reading in a header 🎀

Like literally that's its whole job. It checks the vibe of the current segment and tells you "hey, this is a header situation."

✨ SYNOPSIS ✨

int iscsi_tcp_recv_segment_is_hdr (struct iscsi_tcp_conn *tcp_conn );

so it returns an int and takes exactly one thing. no drama, no extra args, she's lowkey minimal 💅

🦋 ARGUMENTS 🦋

  • tcp_conn — the iscsi tcp conn 💖 that's it, that's the whole parameter list. one connection struct, hand it over, done.

🔥 DESCRIPTION 🔥

returns non zero if we are currently processing or setup to process a header.

no cap, that's the entire behaviour. non-zero = header mode activated 👑 zero = not header mode, we're doing something else bestie. and yes, it covers both "we're doing it right now" and "we're all set up to do it" — both of those count as a non-zero return fr fr ⭐

it's a vibe check for headers. a header vibe check, if you will 🌈

🌟 SEE ALSO 🌟

okay so the kernel file for all this lives at ./drivers/scsi/libiscsi_tcp.c — and here's the whole squad of related functions, all of them, not skipping a single one 🫶

go read them, they're iconic, iykyk 💜

💀 friendly reminder: this is kernel-level stuff, so if you're poking at these functions you are literally in the iSCSI TCP receive path. main character energy, but also be careful bestie 😭

mwah 💖 that's the page! it lives down in ./drivers/scsi, dated October 2026, and it's part of the Kernel API Manual — same header, same footer, same energy, just with way more sparkle ✨🎀 slay, periodt 👑
