ynl-gen-c generates e.g. 'calloc(mcast_groups, sizeof(*dst->mcast_groups))' for array-nest attrs when it should be 'n_mcast_groups'. Add a 'n_' prefix in the generated code for array-nests. Signed-off-by:

ynl does not handle NlError exceptions so they get reported like program failures. Handle the NlError exceptions and report the netlink errors more cleanly. Example now: Netlink error: No such file or directory nl_len = 44 (28) nl_flags = 0x300 nl_type = 2 error: -2 extack: {'bad-attr': '.op'} Example before: Traceback (most recent call last): File "/home/donaldh/net-next/./tools/net/ynl/cli.py", line 81, in <module> main() File "/home/donaldh/net-next/./tools/net/ynl/cli.py", line 69, in main reply = ynl.dump(args.dump, attrs) ^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/home/donaldh/net-next/tools/net/ynl/lib/ynl.py", line 906, in dump return self._op(method, vals, [], dump=True) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/home/donaldh/net-next/tools/net/ynl/lib/ynl.py", line 872, in _op raise NlError(nl_msg) lib.ynl.NlError: Netlink error: No such file or directory nl_len = 44 (28) nl_flags = 0x300 nl_type = 2 error: -2 extack: {'bad-attr': '.op'} Signed-off-by: -

Donald points out that we don't check for overflows. Stash the length of the message on nlmsg_pid (nlmsg_seq would do as well). This allows the attribute helpers to remain self-contained (no extra arguments). Also let the put helpers continue to return nothing. The error is checked only in (newly introduced) ynl_msg_end().

Jason Xing says: ==================== tcp: add two missing addresses when using trace When I reviewed other people's patch [1], I noticed that similar things also happen in tcp_event_skb class and tcp_event_sk_skb class. They don't print those two addrs of skb/sk which already exist. In this patch, I just do as other trace functions do, like trace_net_dev_start_xmit(), to know the exact flow or skb we would like to know in case some systems doesn't support BPF programs well or we have to use /sys/kernel/debug/tracing only for some reasons.

Pablo Neira Ayuso says: ==================== Netfilter fixes for net The following patchset contains fixes for net: Patch #1 disallows anonymous sets with timeout, except for dynamic sets. Anonymous sets with timeouts using the pipapo set backend makes no sense from userspace perspective. Patch #2 rejects constant sets with timeout which has no practical usecase. This kind of set, once bound, contains elements that expire but no new elements can be added. Patch #3 restores custom conntrack expectations with NFPROTO_INET, from Florian Westphal. Patch #4 marks rhashtable anonymous set with timeout as dead from the commit path to avoid that async GC collects these elements. Rules that refers to the anonymous set get released with no mutex held from the commit path. Patch #5 fixes a UBSAN shift overflow in H.323 conntrack helper, from Lena Wang. netfilter pull request 24-03-07 * tag 'nf-24-03-07' of git://git.kernel.org/pub/scm/linux/kernel/git/netfilter/nf: netfilter: nf_conntrack_h323: Add protection for bmp length out of range netfilter: nf_tables: mark set as dead when unbinding anonymous set with timeout netfilter: nft_ct: fix l3num expectations with inet pseudo family netfilter: nf_tables: reject constant set with timeout netfilter: nf_tables: disallow anonymous set with timeout flag ==================== Link: https://lore.kernel.org/r/20240307021545.149386-1-pablo@netfilter.orgSigned-off-by: -

This patch updates the mlxbf_gige driver to support the "get_pause_stats()" callback, which enables display of pause frame counters via "ethtool -I -a oob_net0". The pause frame counters are only enabled if the "counters_en" bit is asserted in the LLU general config register. The driver will only report stats, and thus overwrite the default stats state of ETHTOOL_STAT_NOT_SET, if "counters_en" is asserted. Reviewed-by:

Kernel bot has discovered that if CONFIG_GPIOLIB is not set compilation will fail. Upon investigation the issue is that qca807x_gpio() is guarded by a preprocessor check but then it is called under if (IS_ENABLED(CONFIG_GPIOLIB)) in the probe call so the compiler will error out since qca807x_gpio() has not been declared if CONFIG_GPIOLIB has not been set.

With commit 34d21de9 ("net: Move {l,t,d}stats allocation to core and convert veth & vrf"), stats allocation could be done on net core instead of in this driver. With this new approach, the driver doesn't have to bother with error handling (allocation failure checking, making sure free happens in the right spot, etc). This is core responsibility now. Remove the allocation in the geneve driver and leverage the network core allocation instead. Signed-off-by:
