When flushing the backlog after decoding a record we don't really know how much data the caller want us to evaluate, so use INT_MAX and 0 as arguments to tls_read_flush_backlog() to ensure we flush at 128k of data. Otherwise we might be reading too much data and trigger a TCP window full. Suggested-by:

For now, No matter what error pointer ip_neigh_for_gw() returns, ip_finish_output2() always return -EINVAL, which may mislead the upper users. For exemple, an application uses sendto to send an UDP packet, but when the neighbor table overflows, sendto() will get a value of -EINVAL, and it will cause users to waste a lot of time checking parameters for errors. Return the real errno instead of -EINVAL. Signed-off-by:

The commit d73ef2d6 ("rtnetlink: let rtnl_bridge_setlink checks IFLA_BRIDGE_MODE length") added the nla_len check in rtnl_bridge_setlink, which is the only caller for ndo_bridge_setlink handlers defined in low-level driver codes. Hence, this patch cleanups the redundant checks in each ndo_bridge_setlink handler function. Suggested-by:

Alexander Lobakin says: ==================== page_pool: a couple of assorted optimizations That initially was a spin-off of the IAVF PP series[0], but has grown (and shrunk) since then a bunch. In fact, it consists of three semi-independent blocks: * #1-2: Compile-time optimization. Split page_pool.h into 2 headers to not overbloat the consumers not needing complex inline helpers and then stop including it in skbuff.h at all. The first patch is also prereq for the whole series. * #3: Improve cacheline locality for users of the Page Pool frag API. * #4-6: Use direct cache recycling more aggressively, when it is safe obviously. In addition, make sure nobody wants to use Page Pool API with disabled interrupts. Patches #1 and #5 are authored by Yunsheng and Jakub respectively, with small modifications from my side as per ML discussions. For the perf numbers for #3-6, please see individual commit messages. Also available on my GH with many more Page Pool goodies[1].

Commit 8c48eea3 ("page_pool: allow caching from safely localized NAPI") allowed direct recycling of skb pages to their PP for some cases, but unfortunately missed a couple of other majors. For example, %XDP_DROP in skb mode. The netstack just calls kfree_skb(), which unconditionally passes `false` as @napi_safe. Thus, all pages go through ptr_ring and locks, although most of time we're actually inside the NAPI polling this PP is linked with, so that it would be perfectly safe to recycle pages directly. Let's address such. If @napi_safe is true, we're fine, don't change anything for this path. But if it's false, check whether we are in the softirq context. It will most likely be so and then if ->list_owner is our current CPU, we're good to use direct recycling, even though @napi_safe is false -- concurrent access is excluded. in_softirq() protection is needed mostly due to we can hit this place in the process context (not the hardirq though). For the mentioned xdp-drop-skb-mode case, the improvement I got is 3-4% in Mpps. As for page_pool stats, recycle_ring is now 0 and alloc_slow counter doesn't change most of time, which means the MM layer is not even called to allocate any new pages.
