nfnetlink_hook.c: In function 'nfnl_hook_put_nft_chain_info': nfnetlink_hook.c:76:7: error: implicit declaration of 'nft_is_active' This macro is only defined when NF_TABLES is enabled. While its possible to also add an ifdef-guard, the infrastructure is currently not useful without nf_tables. Reported-by:

While iterating through an SCTP packet's chunks, skb_header_pointer() is called for the minimum expected chunk header size. If (that part of) the skbuff is non-linear, the following memcpy() may read data past temporary buffer '_sch'. Use skb_copy_bits() instead which does the right thing in this situation.

This nfnl subsystem allows to dump the list of all active netfiler hooks, e.g. defrag, conntrack, nf/ip/arp/ip6tables and so on. This helps to see what kind of features are currently enabled in the network stack. Sample output from nft tool using this infra: $ nft list hook ip input family ip hook input { +0000000010 nft_do_chain_inet [nf_tables] # nft table firewalld INPUT +0000000100 nf_nat_ipv4_local_in [nf_nat] +2147483647 ipv4_confirm [nf_conntrack] } Signed-off-by: -

This will allow a followup patch to treat the 'ops->priv' pointer as nft_chain argument without having to first walk the table/chains to check if there is a matching base chain pointer. Signed-off-by:

Currently the aging period for tcp/udp connections is hard coded to 30 seconds. Aged tcp/udp connections configure a hard coded 120/30 seconds pickup timeout for conntrack. This configuration may be too aggressive or permissive for some users. Dynamically configure the nf flow table GC timeout intervals according to the user defined values. Signed-off-by:

Once aged, ownership is returned to conntrack with a hard coded pickup time of 30 seconds, after which the connection may be deleted. eted. The current aging intervals may be too aggressive for some users.

Replace nft_ctx_init_from_setattr() by nft_table_lookup(). This patch also disentangles nf_tables_delset() where NFTA_SET_TABLE is required while nft_ctx_init_from_setattr() allows it to be optional. From the nf_tables_delset() path, this also allows to set up the context structure when it is needed. Removing this helper function saves us 14 LoC, so it is not helping to consolidate code.

Replace nft_ctx_init_from_elemattr() by nft_table_lookup() and set up the context structure right before it is really needed. Moreover, nft_ctx_init_from_elemattr() is setting up the context structure for codepaths where this is not really needed at all. This helper function is also not helping to consolidate code, removing it saves us 4 LoC. Signed-off-by: -

Add an inbound policy filter which matches the HSR/PRP supervision MAC range and forwards to the CPU port without discarding duplicates. This is required to correctly populate time_in[A] and time_in[B] in the HSR/PRP node_table. Leave the policy disabled by default and enable/disable it when joining/leaving hsr. Signed-off-by:

The supplied buffer for the MAC address might not be aligned. Thus doing a 32bit (or 16bit) access could be on an unaligned address. For now, enetc is only used on aarch64 which can do unaligned accesses, thus there is no error. In any case, be correct and use the get/put_unaligned helpers. Signed-off-by:

Mat Martineau says: ==================== mptcp: Add timestamp support Enable the SO_TIMESTAMP and SO_TIMESTAMPING socket options for MPTCP sockets and add receive path cmsg support for timestamps. Patches 1, 2, and 5 expose existing sock and tcp helpers for timestamps (no new EXPORT_SYMBOLS()s). Patch 3 propagates timestamp options to subflows. Patch 4 cleans up MPTCP handling of SOL_SOCKET options. Patch 6 adds timestamp csmg data when receiving on sockets that have been configured for timestamps. Patch 7 adds self test coverage for timestamps. ==================== Signed-off-by: -

Move the pre-check to the function that handles all SOL_SOCKET values. At this point there is complete coverage for all values that were accepted by the pre-check.
