Packets need to be at least 64 bytes to enter the switch port logic, including the FCS, otherwise they will be discarded as RUNT packets. With packets having Broadcom tags, the 4-bytes tag is first stripped off the packet, and the packet length is then checked, so we need to make sure that the packet length with FCS is at least 64 bytes.

BPF interpreter executes the program in 30 nsec. The difference in generated assembler is due to the following: Old BPF imlements LDX_MSH instruction via sk_load_byte_msh() helper function inside bpf_jit.S. New JIT removes the helper and does it explicitly, so ldx_msh cost is the same for both JITs, but generated code looks longer. New JIT has 4 registers to save, so prologue/epilogue are larger, but the cost is within noise on x64. Old JIT checks whether first insn clears A and if not emits 'xor %eax,%eax'. New JIT clears %rax unconditionally. 2. old BPF JIT doesn't support ANC_NLATTR, ANC_PAY_OFFSET, ANC_RANDOM extensions. New JIT supports all BPF extensions. Performance of such filters improves 2-4 times depending on a filter. The longer the filter the higher performance gain. Synthetic benchmarks with many ancillary loads see 20x speedup which seems to be the maximum gain from JIT Notes: . net.core.bpf_jit_enable=2 + tools/net/bpf_jit_disasm is still functional and can be used to see generated assembler . there are two jit_compile() functions and code flow for classic filters is: sk_attach_filter() - load classic BPF bpf_jit_compile() - try to JIT from classic BPF sk_convert_filter() - convert classic to internal bpf_int_jit_compile() - JIT from internal BPF seccomp and tracing filters will just call bpf_int_jit_compile() Signed-off-by: NAlexei Starovoitov <ast@plumgrid.com> Signed-off-by: NDavid S.

Currently, 6lowpan creates one 802.15.4 MAC header for the original packet the device was given by upper layers and reuses this header for all fragments, if fragmentation is required. This also reuses frame sequence numbers, which must not happen. 6lowpan also has issues with fragmentation in the presence of security headers, since those may imply the presence of trailing fields that are not accounted for by the fragmentation code right now. Fix both of these issues by properly allocating fragment skbs with headromm and tailroom as specified by the underlying device, create one header for each skb instead of reusing the original header, let the underlying device do the rest.

The current mac_cb handling of ieee802154 is rather awkward and limited. Decompose the single flags field into multiple fields with the meanings of each subfield of the flags field to make future extensions (for example, link-layer security) easier. Also don't set the frame sequence number in upper layers, since that's a thing the MAC is supposed to set on frame transmit - we set it on header creation, but assuming that upper layers do not blindly duplicate our headers, this is fine.

When dealing with 802.15.4, one often has to know the maximum payload size for a given packet. This depends on many factors, one of which is whether or not a security header is present in the frame. These definitions and functions provide an easy way for any upper layer to calculate the maximum payload size for a packet. The first obvious user for this is 6lowpan, which duplicates this calculation and gets it partially wrong because it ignores security headers.

This Patches solves an issue that could raise when modifying the device's MAC. It occurs due to a simultaneous access to priv->mac_hash from two contexts. The buggy scenario described below: Context 1: copy the new mac address to the dev->dev_addr field. Context 2: mlx4_en_do_uc_filter removes prev_mac entry from the mac_hash db since it is not in dev->uc and not equal to dev->dev_addr. Context 1: mlx4_en_do_set_mac() calls mlx4_en_replace_mac() to replace prev_mac with dev_addr but it fails to update the mac_hash db since it no longer contains prev_mac, therefore it returns with an error. The fix is to prevent mlx4_en_do_uc_filter from being executed by both of the context 1 calls described above, This is done by putting them both under the mdev->state_lock lock, it will solve this issue since mlx4_en_do_uc_filter is already protected by the mdev->state_lock.

This patch fix an issue that happen when changing the MAC address when the port is down, described as follows: 1. Set the port down. 2. Change the MAC address - mlx4_en_set_mac() will change dev->dev_addr. 3. Set the port up - will result in mlx4_en_do_uc_filter that will remove the prev_mac entry from the mac_hash db. 4. Changing the MAC address again will eventually trigger the call to mlx4_en_replace_mac() in order to replace prev_mac with dev_addr but the prev_mac entry is already not exist in the mac_hash db therefore the operation fails. The fix is to set the prev_mac with the new MAC address so in step 3 above, after setting the port up mlx4_en_get_qp() is updating the mac_hash with the entry of dev_addr which is equal to prev_mac. Therefore in step 4, when calling mlx4_en_replace_mac, the entry related to prev_mac exist in mac_hash and the replace operation succeed.

ip_local_port_range is already per netns, so should ip_local_reserved_ports be. And since it is none by default we don't actually need it when we don't enable CONFIG_SYSCTL. By the way, rename inet_is_reserved_local_port() to inet_is_local_reserved_port() Cc: "David S.
