2020-06-25mac80211: fix control port tx status checkMarkus Theil
The initial control port tx status patch assumed, that we have IEEE 802.11 frames, but actually ethernet frames are stored in the ack skb. Fix this by checking for the correct ethertype and skb protocol 802.3. Also allow tx status reports for ETH_P_PREAUTH, as preauth frames can also be send over the nl80211 control port.

2020-06-24net: enetc add tc flower offload flow metering policing actionPo Liu
Flow metering entries in IEEE 802.1Qci is an optional function for a flow filtering module. Flow metering is two rates two buckets and three color marker to policing the frames. This patch only enable one rate one bucket and in color blind mode. Flow metering instance are as specified in the algorithm in MEF 10.3 and in Bandwidth Profile Parameters. They are: a) Flow meter instance identifier. An integer value identifying the flow meter instance. The patch use the police 'index' as thin value. b) Committed Information Rate (CIR), in bits per second. This patch use the 'rate_bytes_ps' represent this value. c) Committed Burst Size (CBS), in octets. This patch use the 'burst' represent this value. d) Excess Information Rate (EIR), in bits per second. e) Excess Burst Size per Bandwidth Profile Flow (EBS), in octets. And plus some other parameters. This patch set EIR/EBS default disable and color blind mode. v1->v2 changes: - Use div_u64() as division replace the '/' report: All errors (new ones prefixed by >>): ld: drivers/net/ethernet/freescale/enetc/enetc_qos.o: in function `enetc_flowmeter_hw_set': >> enetc_qos.c:(.text+0x66): undefined reference to `__udivdi3' Reported-by: kernel test robot <lkp@intel.com> Signed-off-by: Po Liu <Po.Liu@nxp.com> Signed-off-by: David S.

2020-06-24Merge branch 'net-bcmgenet-use-hardware-padding-of-runt-frames'David S. Miller
Doug Berger says: ==================== net: bcmgenet: use hardware padding of runt frames Now that scatter-gather and tx-checksumming are enabled by default it revealed a packet corruption issue that can occur for very short fragmented packets. When padding these frames to the minimum length it is possible for the non-linear (fragment) data to be added to the end of the linear header in an SKB. Since the number of fragments is read before the padding and used afterward without reloading, the fragment that should have been consumed can be tacked on in place of part of the padding. The third commit in this set corrects this by removing the software padding and allowing the hardware to add the pad bytes if necessary. The first two commits resolve warnings observed by the kbuild test robot and are included here for simplicity of application. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
2020-06-24net: bcmgenet: use hardware padding of runt framesDoug Berger
When commit 474ea9cafc45 ("net: bcmgenet: correctly pad short packets") added the call to skb_padto() it should have been located before the nr_frags parameter was read since that value could be changed when padding packets with lengths between 55 and 59 bytes (inclusive). The use of a stale nr_frags value can cause corruption of the pad data when tx-scatter-gather is enabled. This corruption of the pad can cause invalid checksum computation when hardware offload of tx-checksum is also enabled. Since the original reason for the padding was corrected by commit 7dd399130efb ("net: bcmgenet: fix skb_len in bcmgenet_xmit_single()") we can remove the software padding all together and make use of hardware padding of short frames as long as the hardware also always appends the FCS value to the frame.

2020-06-24Merge branch 'bpf_iter_tcp_udp'Alexei Starovoitov
Yonghong Song says: ==================== bpf iterator implments traversal of kernel data structures and these data structures are passed to a bpf program for processing. This gives great flexibility for users to examine kernel data structure without using e.g. /proc/net which has limited and fixed format. Commit 138d0be35b14 ("net: bpf: Add netlink and ipv6_route bpf_iter targets") implemented bpf iterators for netlink and ipv6_route. This patch set intends to implement bpf iterators for tcp and udp. Currently, /proc/net/tcp is used to print tcp4 stats and /proc/net/tcp6 is used to print tcp6 stats. /proc/net/udp[6] have similar usage model. In contrast, only one tcp iterator is implemented and it is bpf program resposibility to filter based on socket family. The same is for udp. This will avoid another unnecessary traversal pass if users want to check both tcp4 and tcp6. Several helpers are also implemented in this patch bpf_skc_to_{tcp, tcp6, tcp_timewait, tcp_request, udp6}_sock The argument for these helpers is not a fixed btf_id. For example, bpf_skc_to_tcp(struct sock_common *), or bpf_skc_to_tcp(struct sock *), or bpf_skc_to_tcp(struct inet_sock *), ... are all valid. At runtime, the helper will check whether pointer cast is legal or not. Please see Patch #5 for details. Since btf_id's for both arguments and return value are known at build time, the btf_id's are pre-computed once vmlinux btf becomes valid. Jiri's "adding d_path helper" patch set https://lore.kernel.org/bpf/20200616100512.2168860-1-jolsa@kernel.org/T/ provides a way to pre-compute btf id during vmlinux build time. This can be applied here as well. A followup patch can convert to build time btf id computation after Jiri's patch landed. Changelogs: v4 -> v5: - fix bpf_skc_to_udp6_sock helper as besides sk_protocol, sk_family, sk_type == SOCK_DGRAM is also needed to differentiate from SOCK_RAW (Eric) v3 -> v4: - fix bpf_skc_to_{tcp_timewait, tcp_request}_sock helper implementation as just checking sk->sk_state is not enough (Martin) - fix a few kernel test robot reported failures - move bpf_tracing_net.h from libbpf to selftests (Andrii) - remove __weak attribute from selftests CONFIG_HZ variables (Andrii) v2 -> v3: - change sock_cast*/SOCK_CAST* names to btf_sock* names for generality (Martin) - change gpl_license to false (Martin) - fix helper to cast to tcp timewait/request socket.

All possible argument btf_id and return value btf_id for helper bpf_skc_to_tcp6_sock() are pre-calculcated and cached.

A new field bpf_seq_afinfo is added to tcp_iter_state to provide bpf tcp iterator afinfo. There are two reasons on why we did this. First, the current way to get afinfo from PDE_DATA does not work for bpf iterator as its seq_file inode does not conform to /proc/net/{tcp,tcp6} inode structures. More specifically, anonymous bpf iterator will use an anonymous inode which is shared in the system and we cannot change inode private data structure at all. Second, bpf iterator for tcp/tcp6 wants to traverse all tcp and tcp6 sockets in one pass and bpf program can control whether they want to skip one sk_family or not. Having a different afinfo with family AF_UNSPEC make it easier to understand in the code. This patch does not change /proc/net/{tcp,tcp6} behavior as the bpf_seq_afinfo will be NULL for these two proc files.

2020-06-24ima: extend boot_aggregate with kernel measurementsMaurizio Drocco
Registers 8-9 are used to store measurements of the kernel and its command line (e.g., grub2 bootloader with tpm module enabled). IMA should include them in the boot aggregate. Registers 8-9 should be only included in non-SHA1 digests to avoid ambiguity.

2020-06-25netfilter: ipset: fix unaligned atomic accessRussell King
When using ip_set with counters and comment, traffic causes the kernel to panic on 32-bit ARM: Alignment trap: not handling instruction e1b82f9f at [<bf01b0dc>] Unhandled fault: alignment exception (0x221) at 0xea08133c PC is at ip_set_match_extensions+0xe0/0x224 [ip_set] The problem occurs when we try to update the 64-bit counters - the faulting address above is not 64-bit aligned. The problem occurs due to the way elements are allocated, for example: set->dsize = ip_set_elem_len(set, tb, 0, 0); map = ip_set_alloc(sizeof(*map) + elements * set->dsize); If the element has a requirement for a member to be 64-bit aligned, and set->dsize is not a multiple of 8, but is a multiple of four, then every odd numbered elements will be misaligned - and hitting an atomic64_add() on that element will cause the kernel to panic. ip_set_elem_len() must return a size that is rounded to the maximum alignment of any extension field stored in the element. This change ensures that is the case.

When writing the serdes configuration register was moved to mvneta_config_interface() the whole code block was removed from mvneta_port_power_up() in the assumption that its only purpose was to write the serdes configuration register. As mentioned by Russell King its purpose was also to check for valid interface modes early so that later in the driver we do not have to care for unexpected interface modes.
