linux-next build bot reported compile issue [1] with one of its configs. It looks like when we have CONFIG_NET=n and CONFIG_BPF{,_SYSCALL}=y, we are missing the bpf_base_func_proto definition (from net/core/filter.c) in cgroup_base_func_proto. I'm reshuffling the code a bit to make it work. The common helpers are moved into kernel/bpf/helpers.c and the bpf_base_func_proto is exported from there. Also, bpf_get_raw_cpu_id goes into kernel/bpf/core.c akin to existing bpf_user_rnd_u32.

This patch fixes an off by one error in the RV32 JIT handling for BPF tail call. Currently, the code decrements TCC before checking if it is less than zero. This limits the maximum number of tail calls to 32 instead of 33 as in other JITs. The fix is to instead check the old value of TCC before decrementing.

The following error was shown when a bpf program was compiled without vmlinux.h auto-generated from BTF: # clang -I./linux/tools/lib/ -I/lib/modules/$(uname -r)/build/include/ \ -O2 -Wall -target bpf -emit-llvm -c bpf_prog.c -o bpf_prog.bc ... In file included from linux/tools/lib/bpf/bpf_helpers.h:5: linux/tools/lib/bpf/bpf_helper_defs.h:56:82: error: unknown type name '__u64' ... It seems that bpf programs are intended for being built together with the vmlinux.h (which will have all the __u64 and other typedefs). But users may mistakenly think "include <linux/types.h>" is missing because the vmlinux.h is not common for non-bpf developers. IMO, an explicit comment therefore should be added to bpf_helpers.h as this patch shows.

Currently the following prog types don't fall back to bpf_base_func_proto() (instead they have cgroup_base_func_proto which has a limited set of helpers from bpf_base_func_proto): * BPF_PROG_TYPE_CGROUP_DEVICE * BPF_PROG_TYPE_CGROUP_SYSCTL * BPF_PROG_TYPE_CGROUP_SOCKOPT I don't see any specific reason why we shouldn't use bpf_base_func_proto(), every other type of program (except bpf-lirc and, understandably, tracing) use it, so let's fall back to bpf_base_func_proto for those prog types as well. This basically boils down to adding access to the following helpers: * BPF_FUNC_get_prandom_u32 * BPF_FUNC_get_smp_processor_id * BPF_FUNC_get_numa_node_id * BPF_FUNC_tail_call * BPF_FUNC_ktime_get_ns * BPF_FUNC_spin_lock (CAP_SYS_ADMIN) * BPF_FUNC_spin_unlock (CAP_SYS_ADMIN) * BPF_FUNC_jiffies64 (CAP_SYS_ADMIN) I've also added bpf_perf_event_output() because it's really handy for logging and debugging.

In MPTCP, the receive window is shared across all subflows, because it refers to the mptcp-level sequence space. MPTCP receivers already place incoming packets on the mptcp socket receive queue and will charge it to the mptcp socket rcvbuf until userspace consumes the data. Update __tcp_select_window to use the occupancy of the parent/mptcp socket instead of the subflow socket in case the tcp socket is part of a logical mptcp connection. This commit doesn't change choice of initial window for passive or active connections. While it would be possible to change those as well, this adds complexity (especially when handling MP_JOIN requests). Furthermore, the MPTCP RFC specifically says that a MPTCP sender 'MUST NOT use the RCV.WND field of a TCP segment at the connection level if it does not also carry a DSS option with a Data ACK field.' SYN/SYNACK packets do not carry a DSS option with a Data ACK field. Signed-off-by: NFlorian Westphal <fw@strlen.de> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Currently, the PF driver removes all (including its VFs') MAC/VLAN flow director table entries when resetting, and restores them after reset completed. In fact, the hardware will clear all table entries only in IMP reset and global reset. So driver only needs to restore the table entries in these cases, and needs do nothing when PF reset, FLR or other function level reset. This patch optimizes it by removing unnecessary table entries clear and restoring handling in the reset flow, and doing the restoring after reset completed.

Currently, the driver use mutex umv_lock to protect the variable vport->share_umv_size. And there is already a mutex vport_lock being defined in the driver, which is designed to protect the resource of vport. So we can use vport_lock instead of umv_lock. Furthermore, there is a time window for protect share_umv_size between checking UMV space and doing MAC configuration in the lin function hclge_add_uc_addr_common(). It should be extended. This patch uses mutex vport_lock intead of spin lock umv_lock to protect share_umv_size, and adjusts the mutex's range.

As the HNS3 driver doesn't update the MAC address directly in function hns3_set_rx_mode() now, it can't know whether the MAC table is full from __dev_uc_sync() and __dev_mc_sync(), so it's senseless to handle the overflow promisc here.

Currently, the HNS3 driver sync and unsync MAC address in function hns3_set_rx_mode(). For PF, it adds and deletes MAC address directly in the path of dev_set_rx_mode(). If failed, it won't retry until next calling of hns3_set_rx_mode(). On the other hand, if request add and remove a same address many times at a short interval, each request must be done one by one, can't be merged. For VF, it sends mailbox messages to PF to request adding or deleting MAC address in the path of function hns3_set_rx_mode(), no matter the address is configured success. This patch refines it by recording the MAC address in function hns3_set_rx_mode(), and updating MAC address in the service task. If failed, it will retry by the next calling of periodical service task. It also uses some state to mark the state of each MAC address in the MAC list, which can help merge configure request for a same address. With these changes, when global reset or IMP reset occurs, we can restore the MAC table with the MAC list.
