xdr_skb_read_bits(9)

💖 xdr_skb_read_bits 💖

okay so bestie, welcome to xdr_skb_read_bits(9) — yes that's the section 9 kernel API manual, we're in the big leagues now, and no I'm not scared of it 💅

---

✨ NAME ✨

xdr_skb_read_bits — copy some data bits from skb to internal buffer

like literally, it scoops bits out of an skb and drops them in your own little buffer 🎀

🌸 SYNOPSIS 🌸

size_t xdr_skb_read_bits (struct xdr_skb_reader *desc , void *to ,
       size_t len );

that's the whole vibe. three args, one size_t coming back at you 🦋

🍓 ARGUMENTS 🍓

• desc — the sk_buff copy helper, your little main character struct that knows how to do the copying 🫶
• to — copy destination, aka where the bytes are actually going, the it-girl of this whole operation 💖
• len — number of bytes to copy, so pls count responsibly ✨

👑 DESCRIPTION 👑

Possibly called several times to iterate over an sk_buff and copy data out of it.

yes bestie, possibly called several times — that's the whole thing. it's not a one-and-done situation, it's a loop girlie, walking over an sk_buff and pulling data out 💀 so don't assume one call eats the whole buffer, okay? iykyk 🌈

🌼 SEE ALSO 🌼

• Kernel file ./net/sunrpc/socklib.c 🧚
• csum_partial_copy_to_xdr(9)
• xprt_sock_sendmsg(9)

those last two are also section 9, so if you liked this one you know where to find the rest of the friend group ⭐

fr fr bestie, that's everything — no cap, no skipped sections, no invented behaviour 💜
