Di Nitto <fdinitto(a)redhat.com> Date: 2026-05-22 (Fri, 22 May 2026) Changed paths: M libknet/handle_api.c M libknet/host.c M libknet/internals.h M libknet/threads_rx.c M libknet/threads_tx.c M libknet/transport_common.c M libknet/transport_common.h Log Message: ----------- libknet: add MSG_EOR support for SOCK_SEQPACKET socketpairs Detected on FreeBSD 15 which changed SOCK_SEQPACKET from atomic datagrams to stream sockets with record markers. This exposed a bug in knet: we were not using MSG_EOR to mark record boundaries as required by the SOCK_SEQPACKET specification (documented in both Linux and FreeBSD man pages). Without MSG_EOR, multiple records can coalesce into single reads, breaking packet boundaries. Signed-off-by: Fabio M.

This caused buffers to be reclaimed based on stale sequence information, potentially freeing buffers that should still be valid or keeping buffers that should be reclaimed. Signed-off-by: Fabio M. Di Nitto <fdinitto(a)redhat.com> Co-Authored-By: Claude Sonnet 4.5 <noreply(a)anthropic.com> Commit: 18fbc19b9416d836f0c04e34d0754455c88c254d https://github.com/kronosnet/kronosnet/commit/18fbc19b9416d836f0c04e34d0754… Author: Fabio M. Di Nitto <fdinitto(a)redhat.com> Date: 2026-05-22 (Fri, 22 May 2026) Changed paths: M libknet/host.c Log Message: ----------- libknet: fix sequence number wraparound calculation in defragmentation The distance calculation between sequence numbers was incorrect when wraparound occurred. The formula was backwards: it subtracted in the wrong direction and didn't account for the +1 needed for modular arithmetic. This caused incorrect buffer reclamation decisions near the SEQ_MAX boundary. Practical examples (SEQ_MAX = 65535): Example 1 - Normal case (no wraparound): Last packet: dst_seq_num = 1000 New packet: seq_num = 1005 Expected distance: 5 BEFORE (wrong): seq_dist = dst_seq_num - seq_num = 1000 - 1005 = -5 (negative!) AFTER (correct): seq_dist = seq_num - dst_seq_num = 1005 - 1000 = 5 Example 2 - Wraparound case: Last packet: dst_seq_num = 65534 New packet: seq_num = 3 (wrapped around) Expected distance: 5 (65534→65535→0→1→2→3) BEFORE (wrong): seq_dist = (SEQ_MAX - seq_num) + dst_seq_num seq_dist = (65535 - 3) + 65534 = 131066 (huge wrong number!) AFTER (correct): seq_dist = (SEQ_MAX - dst_seq_num) + seq_num + 1 seq_dist = (65535 - 65534) + 3 + 1 = 5 The +1 accounts for the transition from 65535→0 being one step, not zero. Verification that circular buffer cleaning is not broken: The seq_dist value is used to determine whether the new packet is: a) Within the circular buffer window (seq_dist < KNET_CBUFFER_SIZE) b) Far enough to require full buffer clear (seq_dist > threshold) c) Should trigger incremental cleaning (fall through case) Test case 1 - Normal sequential packet: dst_seq_num = 1000, seq_num = 1005, expected distance = 5 BEFORE: seq_dist = -5 (unsigned overflow ~65530) → Incorrectly clears entire buffer for normal sequential packets! AFTER: seq_dist = 5 → Correctly identifies packet as within buffer window, no clearing needed Test case 2 - Wraparound (close distance): dst_seq_num = 65534, seq_num = 3, expected distance = 5 BEFORE: seq_dist = 131066 → Falls through to circular buffer cleaning code incorrectly AFTER: seq_dist = 5 → Correctly identifies packet as within buffer window Test case 3 - Large jump requiring buffer clear: dst_seq_num = 1000, seq_num = 50000, expected distance = 49000 BEFORE: seq_dist = -49000 (unsigned ~16536) → Clears buffer (correct by accident) AFTER: seq_dist = 49000 → Clears buffer (correct by design) The circular buffer cleaning code (lines 673-684) uses seq_num and dst_seq_num directly via modulo operations to find buffer positions. It does not use seq_dist for position calculations, only for the threshold check to determine whether to run. The fix corrects the threshold logic without affecting the position calculations.

Test scenarios: 1. Normal sequential packets with occasional loss 2. Wraparound boundary (65535->0) with packet loss 3. Large sequence jumps (>KNET_CBUFFER_SIZE) triggering buffer clearing 4. Out-of-order fragment delivery within same sequence number 5. Out-of-order complete packet delivery (different sequence numbers) 6. Extreme packet loss beyond receive window 7. Wraparound with extreme loss (>KNET_CBUFFER_SIZE gap) 8. Wraparound stress with multiple cycles and duplicate detection 9. Fragment corruption across wraparound (historical bug regression test) Signed-off-by: Fabio M.
