Returning the error code via a 'int *ret' when the function returns a pointer is very un-kernely and causes gcc 10's static analysis to choke: net/rds/message.c: In function ‘rds_message_map_pages’: net/rds/message.c:358:10: warning: ‘ret’ may be used uninitialized in this function [-Wmaybe-uninitialized] 358 | return ERR_PTR(ret); Use a typical ERR_PTR return instead.

To rehash a previous explanation given in commit 1c44ce56 ("net: mscc: ocelot: fix vlan_filtering when enslaving to bridge before link is up"), the switch driver operates the in a mode where a single VLAN can be transmitted as untagged on a particular egress port. That is the "native VLAN on trunk port" use case. The configuration for this native VLAN is driven in 2 ways: - Set the egress port rewriter to strip the VLAN tag for the native VID (as it is egress-untagged, after all). - Configure the ingress port to drop untagged and priority-tagged traffic, if there is no native VLAN. The intention of this setting is that a trunk port with no native VLAN should not accept untagged traffic. Since both of the above configurations for the native VLAN should only be done if VLAN awareness is requested, they are actually done from the ocelot_port_vlan_filtering function, after the basic procedure of toggling the VLAN awareness flag of the port. But there's a problem with that simplistic approach: we are trying to juggle with 2 independent variables from a single function: - Native VLAN of the port - its value is held in port->vid. - VLAN awareness state of the port - currently there are some issues here, more on that later*. The actual problem can be seen when enslaving the switch ports to a VLAN filtering bridge: 0. The driver configures a pvid of zero for each port, when in standalone mode. While the bridge configures a default_pvid of 1 for each port that gets added as a slave to it. 1. The bridge calls ocelot_port_vlan_filtering with vlan_aware=true. The VLAN-filtering-dependent portion of the native VLAN configuration is done, considering that the native VLAN is 0. 2. The bridge calls ocelot_vlan_add with vid=1, pvid=true, untagged=true. The native VLAN changes to 1 (change which gets propagated to hardware). 3. ??? - nobody calls ocelot_port_vlan_filtering again, to reapply the VLAN-filtering-dependent portion of the native VLAN configuration, for the new native VLAN of 1. One can notice that after toggling "ip link set dev br0 type bridge vlan_filtering 0 && ip link set dev br0 type bridge vlan_filtering 1", the new native VLAN finally makes it through and untagged traffic finally starts flowing again. But obviously that shouldn't be needed. So it is clear that 2 independent variables need to both re-trigger the native VLAN configuration. So we introduce the second variable as ocelot_port->vlan_aware. *Actually both the DSA Felix driver and the Ocelot driver already had each its own variable: - Ocelot: ocelot_port_private->vlan_aware - Felix: dsa_port->vlan_filtering but the common Ocelot library needs to work with a single, common, variable, so there is some refactoring done to move the vlan_aware property from the private structure into the common ocelot_port structure.

For some types of BPF programs that utilize expected_attach_type, libbpf won't set load_attr.expected_attach_type, even if expected_attach_type is known from section definition. This was done to preserve backwards compatibility with old kernels that didn't recognize expected_attach_type attribute yet (which was added in 5e43f899 ("bpf: Check attach type at prog load time"). But this is problematic for some BPF programs that utilize newer features that require kernel to know specific expected_attach_type (e.g., extended set of return codes for cgroup_skb/egress programs). This patch makes libbpf specify expected_attach_type by default, but also detect support for this field in kernel and not set it during program load. This allows to have a good metadata for bpf_program (e.g., bpf_program__get_extected_attach_type()), but still work with old kernels (for cases where it can work at all). Additionally, due to expected_attach_type being always set for recognized program types, bpf_program__attach_cgroup doesn't have to do extra checks to determine correct attach type, so remove that additional logic. Also adjust section_names selftest to account for this change. More detailed discussion can be found in [0].

Russell King says: ==================== Fix 88x3310 leaving power save mode This series fixes a problem with the 88x3310 PHY on Macchiatobin coming out of powersave mode noticed by Matteo Croce. It seems that certain PHY firmwares do not properly exit powersave mode, resulting in a fibre link not coming up. The solution appears to be to soft-reset the PHY after clearing the powersave bit. We add support for reporting the PHY firmware version to the kernel log, and use it to trigger this new behaviour if we have v0.3.x.x or more recent firmware on the PHY. This, however, is a guess as the firmware revision documentation does not mention this issue, and we know that v0.2.1.0 works without this fix but v0.3.3.0 and later does not. ==================== Signed-off-by: -

Andrew Lunn says: ==================== mv88e6xxx fixed link fixes Recent changes for how the MAC is configured broke fixed links, as used by CPU/DSA ports, and for SFPs when phylink cannot be used. The first fix is unchanged from v1. The second fix takes a different solution than v1. If a CPU or DSA port is known to have a PHYLINK instance, configure the port down before instantiating the PHYLINK, so it is in the down state as expected by PHYLINK. ==================== Signed-off-by: -
Andrew Lunn authored
DSA and CPU ports can be configured in two ways. By default, the driver should configure such ports to there maximum bandwidth. For most use cases, this is sufficient. When this default is insufficient, a phylink instance can be bound to such ports, and phylink will configure the port, e.g. based on fixed-link properties. phylink assumes the port is initially down. Given that the driver should have already configured it to its maximum speed, ask the driver to down the port before instantiating the phylink instance.

The 88e6185 is reporting it has detected a PHY, when a port is connected to an SFP. As a result, the fixed-phy configuration is not being applied. That then breaks packet transfer, since the port is reported as being down. Add additional conditions to check the interface mode, and if it is fixed always configure the port on link up/down, independent of the PPU status.

Fix the DATA packet transmission to disable nofrag for UDPv4 on an AF_INET6 socket as well as UDPv6 when trying to transmit fragmentably. Without this, packets filled to the normal size used by the kernel AFS client of 1412 bytes be rejected by udp_sendmsg() with EMSGSIZE immediately. The ->sk_error_report() notification hook is called, but rxrpc doesn't generate a trace for it. This is a temporary fix; a more permanent solution needs to involve changing the size of the packets being filled in accordance with the MTU, which isn't currently done in AF_RXRPC. The reason for not doing so was that, barring the last packet in an rx jumbo packet, jumbos can only be assembled out of 1412-byte packets - and the plan was to construct jumbos on the fly at transmission time. Also, there's no point turning on IPV6_MTU_DISCOVER, since IPv6 has to engage in this anyway since fragmentation is only done by the sender. We can then condense the switch-statement in rxrpc_send_data_packet(). Fixes: 75b54cb5 ("rxrpc: Add IPv6 support") Signed-off-by:

In commit 65c93628 ("bpftool: Add struct_ops support") a new type of command named struct_ops has been added. This command requires a kernel with CONFIG_DEBUG_INFO_BTF=y set and for retrieving BTF info in bpftool, the helper get_btf_vmlinux() is used. When running this command on kernel without BTF debug info, this will lead to 'btf_vmlinux' variable being an invalid(error) pointer. And by this, btf_free() causes a segfault when executing 'bpftool struct_ops'. This commit adds pointer validation with IS_ERR not to free invalid pointer, and this will fix the segfault issue.

VM_MAYWRITE flag during initial memory mapping determines if already mmap()'ed pages can be later remapped as writable ones through mprotect() call. To prevent user application to rewrite contents of memory-mapped as read-only and subsequently frozen BPF map, remove VM_MAYWRITE flag completely on initially read-only mapping. Alternatively, we could treat any memory-mapping on unfrozen map as writable and bump writecnt instead. But there is little legitimate reason to map BPF map as read-only and then re-mmap() it as writable through mprotect(), instead of just mmap()'ing it as read/write from the very beginning. Also, at the suggestion of Jann Horn, drop unnecessary refcounting in mmap operations. We can just rely on VMA holding reference to BPF map's file properly.

This patch fixes an incorrect check in how immediate memory offsets are computed for BPF_DW on arm. For BPF_LDX/ST/STX + BPF_DW, the 32-bit arm JIT breaks down an 8-byte access into two separate 4-byte accesses using off+0 and off+4. If off fits in imm12, the JIT emits a ldr/str instruction with the immediate and avoids the use of a temporary register. While the current check off <= 0xfff ensures that the first immediate off+0 doesn't overflow imm12, it's not sufficient for the second immediate off+4, which may cause the second access of BPF_DW to read/write the wrong address. This patch fixes the problem by changing the check to off <= 0xfff - 4 for BPF_DW, ensuring off+4 will never overflow. A side effect of simplifying the check is that it now allows using negative immediate offsets in ldr/str. This means that small negative offsets can also avoid the use of a temporary register. This patch introduces no new failures in test_verifier or test_bpf.c.
