The SoC family also contains DW8051 block (Intel 8051 compatible CPU core) and an associated SRAM. The corresponding control registers are mapped into RTCSYS address space as well.

2025-07-22selftests: netfilter: tone-down conntrack clash testFlorian Westphal
The test is supposed to observe that the 'clash_resolve' stat counter incremented (i.e., the code path was covered). This check was incorrect, 'conntrack -S' needs to be called in the revevant namespace, not the initial netns. The clash resolution logic in conntrack is only exercised when multiple packets with the same udp quadruple race. Depending on kernel config, number of CPUs, scheduling policy etc. this might not trigger even after several retries. Thus the script eventually returns SKIP if the retry count is exceeded. The udpclash tool with also exit with a failure if it did not observe the expected number of replies. In the script, make a note of this but do not fail anymore, just check if the clash resolution logic triggered after all. Remove the 'single-core' test: while unlikely, with preemptible kernel it should be possible to also trigger clash resolution logic. With this change the test will either SKIP or pass. Hard error could be restored later once its clear whats going on, so also dump 'conntrack -S' when some packets went missing to see if conntrack dropped them on insert.

2025-07-22tcp: do not set a zero size receive bufferPaolo Abeni
The nipa CI is reporting frequent failures in the mptcp_connect self-tests. In the failing scenarios (TCP -> MPTCP) the involved sockets are actually plain TCP ones, as fallback for passive socket at 2whs time cause the MPTCP listener to actually create a TCP socket. The transfer is stuck due to the receiver buffer being zero. With the stronger check in place, tcp_clamp_window() can be invoked while the TCP socket has sk_rmem_alloc == 0, and the receive buffer will be zeroed, too. Check for the critical condition in tcp_prune_queue() and just drop the packet without shrinking the receiver buffer.

2025-07-22tcp: trace retransmit failures in tcp_retransmit_skbFan Yu
Background ========== When TCP retransmits a packet due to missing ACKs, the retransmission may fail for various reasons (e.g., packets stuck in driver queues, receiver zero windows, or routing issues). The original tcp_retransmit_skb tracepoint: 'commit e086101b150a ("tcp: add a tracepoint for tcp retransmission")' lacks visibility into these failure causes, making production diagnostics difficult. Solution ======== Adds the retval("err") to the tcp_retransmit_skb tracepoint. Enables users to know why some tcp retransmission failed and users can filter retransmission failures by retval. Compatibility description ========================= This patch extends the tcp_retransmit_skb tracepoint by adding a new "err" field at the end of its existing structure (within TP_STRUCT__entry). The compatibility implications are detailed as follows: 1) Structural compatibility for legacy user-space tools Legacy tools/BPF programs accessing existing fields (by offset or name) can still work without modification or recompilation.The new field is appended to the end, preserving original memory layout. 2) Note: semantic changes The original tracepoint primarily only focused on successfully retransmitted packets. With this patch, the tracepoint now can figure out packets that may terminate early due to specific reasons. For accurate statistics, users should filter using "err" to distinguish outcomes.
