Extend the bpf(2) syscall by two new commands, BPF_PROG_ATTACH and BPF_PROG_DETACH which allow attaching and detaching eBPF programs to a target. On the API level, the target could be anything that has an fd in userspace, hence the name of the field in union bpf_attr is called 'target_fd'. When called with BPF_ATTACH_TYPE_CGROUP_INET_{E,IN}GRESS, the target is expected to be a valid file descriptor of a cgroup v2 directory which has the bpf controller enabled. These are the only use-cases implemented by this patch at this point, but more can be added. If a program of the given type already exists in the given cgroup, the program is swapped automically, so userspace does not have to drop an existing program first before installing a new one, which would otherwise leave a gap in which no program is attached. For more information on the propagation logic to subcgroups, please refer to the bpf cgroup controller implementation. The API is guarded by CAP_NET_ADMIN.

This patch adds two sets of eBPF program pointers to struct cgroup. One for such that are directly pinned to a cgroup, and one for such that are effective for it. To illustrate the logic behind that, assume the following example cgroup hierarchy. A - B - C \ D - E If only B has a program attached, it will be effective for B, C, D and E. If D then attaches a program itself, that will be effective for both D and E, and the program in B will only affect B and C. Only one program of a given type is effective for a cgroup. Attaching and detaching programs will be done through the bpf(2) syscall. For now, ingress and egress inet socket filtering are the only supported use-cases.

This program type is similar to BPF_PROG_TYPE_SOCKET_FILTER, except that it does not allow BPF_LD_[ABS|IND] instructions and hooks up the bpf_skb_load_bytes() helper. Programs of this type will be attached to cgroups for network filtering and accounting.

Goal is to reorganize this critical structure to increase performance. ndo_start_xmit() should only dirty one cache line, and access as few cache lines as possible.

PHY drivers should be able to rely on the caller of {get,set}_tunable to have acquired the PHY device mutex, in order to both serialize against concurrent calls of these functions, but also against PHY state machine changes. All ethtool PHY-level functions do this, except {get,set}_tunable, so we make them consistent here as well.

In commit 2331ccc5 ("tcp: enhance tcp collapsing"), we made a first step allowing copying right skb to left skb head. Since all skbs in socket write queue are headless (but possibly the very first one), this strategy often does not work.

The VMware VMCI transport supports loopback inside virtual machines. This patch implements loopback for virtio-vsock. Flow control is handled by the virtio-vsock protocol as usual. The sending process stops transmitting on a connection when the peer's receive buffer space is exhausted. Cathy Avery <cavery@redhat.com> noticed this difference between VMCI and virtio-vsock when a test case using loopback failed. Although loopback isn't the main point of AF_VSOCK, it is useful for testing and virtio-vsock must match VMCI semantics so that userspace programs run regardless of the underlying transport. My understanding is that loopback is not supported on the host side with VMCI. Follow that by implementing it only in the guest driver, not the vhost host driver.

git://git.kernel.org/pub/scm/linux/kernel/git/davem/net由 David S. Miller 提交于
All conflicts were simple overlapping changes except perhaps for the Thunder driver. That driver has a change_mtu method explicitly for sending a message to the hardware. If that fails it returns an error. Normally a driver doesn't need an ndo_change_mtu method becuase those are usually just range changes, which are now handled generically. But since this extra operation is needed in the Thunder driver, it has to stay. However, if the message send fails we have to restore the original MTU before the change because the entire call chain expects that if an error is thrown by ndo_change_mtu then the MTU did not change. Therefore code is added to nicvf_change_mtu to remember the original MTU, and to restore it upon nicvf_update_hw_max_frs() failue. Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Both of these drivers won't work on 64-bit architectures unless they are redesigned, since they store a virtual address pointer in a 32-bit field of the descriptors: drivers/net/ethernet/marvell/mvneta_bm.c: In function 'mvneta_bm_construct': drivers/net/ethernet/marvell/mvneta_bm.c:103:16: error: cast from pointer to integer of different size [-Werror=pointer-to-int-cast] drivers/net/ethernet/marvell/mvpp2.c: In function 'mvpp2_prs_vlan_init': drivers/net/ethernet/marvell/mvpp2.c:2563:32: error: large integer implicitly truncated to unsigned type [-Werror=overflow] This limits the COMPILE_TEST option for the two drivers again to only build them on 32-bit. This seems nicer than shutting up the warnings, in case we ever actually want to use them on 64-bit, as the warnings indicate which parts of the driver are currently broken there.

Different families have different sets of statistics. Abstract this using a stats_get_stats op. The mv88e6390 needs a different implementation, which will be added later. Signed-off-by: NAndrew Lunn <andrew@lunn.ch> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Different families have different sets of statistics. Abstract this using a stats_get_sset_count and stats_get_strings op. Each stat has a bitmap, and the ops implementer uses a bit map mask to count the statistics which apply for the family, or return the list of strings.

The statistics unit on the mv88e6390 needs the histogram mode to be configured in a different register compared to other devices. Add an ops to do this. Signed-off-by: NAndrew Lunn <andrew@lunn.ch> v2: Rename to mv88e6390_g1_stats_set_histogram Move into global1.c Signed-off-by: NDavid S. Miller <davem@davemloft.net>

The MV88E6390 has a control register for what the histogram statistics actually contain. This means the stat_snapshot method should not set this information. So implement the 6390 stats_snapshot function without these bits. Signed-off-by: NAndrew Lunn <andrew@lunn.ch> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Knowing the family of device belongs to helps with picking the ops implementation which is appropriate to the device. So add a comment to each structure of ops. Signed-off-by: NAndrew Lunn <andrew@lunn.ch> Signed-off-by: NDavid S. Miller <davem@davemloft.net>
