2020-12-03security: add const qualifier to struct sock in various placesFlorian Westphal3-4/+4
A followup change to tcp_request_sock_op would have to drop the 'const' qualifier from the 'route_req' function as the 'security_inet_conn_request' call is moved there - and that function expects a 'struct sock *'. However, it turns out its also possible to add a const qualifier to security_inet_conn_request instead.

2020-12-03macvlan: Support for high multicast packet rateThomas Karlsson2-0/+3
Background: Broadcast and multicast packages are enqueued for later processing. This queue was previously hardcoded to 1000. This proved insufficient for handling very high packet rates. This resulted in packet drops for multicast. While at the same time unicast worked fine. The change: This patch make the queue length adjustable to accommodate for environments with very high multicast packet rate. But still keeps the default value of 1000 unless specified. The queue length is specified as a request per macvlan using the IFLA_MACVLAN_BC_QUEUE_LEN parameter. The actual used queue length will then be the maximum of any macvlan connected to the same port. The actual used queue length for the port can be retrieved (read only) by the IFLA_MACVLAN_BC_QUEUE_LEN_USED parameter for verification. This will be followed up by a patch to iproute2 in order to adjust the parameter from userspace.

2020-11-28net/sched: sch_frag: add generic packet fragment support.wenxu2-0/+8
Currently kernel tc subsystem can do conntrack in cat_ct. But when several fragment packets go through the act_ct, function tcf_ct_handle_fragments will defrag the packets to a big one. But the last action will redirect mirred to a device which maybe lead the reassembly big packet over the mtu of target device. This patch add support for a xmit hook to mirred, that gets executed before xmiting the packet. Then, when act_ct gets loaded, it configs that hook. The frag xmit hook maybe reused by other modules.

2020-11-27net: openvswitch: fix TTL decrement action netlink message formatEelco Chaudron1-0/+2
Currently, the openvswitch module is not accepting the correctly formated netlink message for the TTL decrement action. For both setting and getting the dec_ttl action, the actions should be nested in the OVS_DEC_TTL_ATTR_ACTION attribute as mentioned in the openvswitch.h uapi. When the original patch was sent, it was tested with a private OVS userspace implementation. This implementation was unfortunately not upstreamed and reviewed, hence an erroneous version of this patch was sent out. Leaving the patch as-is would cause problems as the kernel module could interpret additional attributes as actions and vice-versa, due to the actions not being encapsulated/nested within the actual attribute, but being concatinated after it.

Fail to do so, results in firmware treating PF's vport as ECPF vport for eswitch ACL tables.

2020-11-26mm: memcg: relayout structure mem_cgroup to avoid cache interferenceFeng Tang1-14/+14
0day reported one -22.7% regression for will-it-scale page_fault2 case [1] on a 4 sockets 144 CPU platform, and bisected to it to be caused by Waiman's optimization (commit bd0b230fe1) of saving one 'struct page_counter' space for 'struct mem_cgroup'. Initially we thought it was due to the cache alignment change introduced by the patch, but further debug shows that it is due to some hot data members ('vmstats_local', 'vmstats_percpu', 'vmstats') sit in 2 adjacent cacheline (2N and 2N+1 cacheline), and when adjacent cache line prefetch is enabled, it triggers an "extended level" of cache false sharing for 2 adjacent cache lines.

tls_device_offload_cleanup_rx doesn't clear tls_ctx->netdev after calling tls_dev_del if TLX TX offload is also enabled. Clearing tls_ctx->netdev gets postponed until tls_device_gc_task. It leaves a time frame when tls_device_down may get called and call tls_dev_del for RX one extra time, confusing the driver, which may lead to a crash. This patch corrects this racy behavior by adding a flag to prevent tls_device_down from calling tls_dev_del the second time.

2020-11-26lockdep: Introduce in_softirq lockdep assertYunsheng Lin1-0/+11
The current semantic for napi_consume_skb() is that caller need to provide non-zero budget when calling from NAPI context, and breaking this semantic will cause hard to debug problem, because _kfree_skb_defer() need to run in atomic context in order to push the skb to the particular cpu' napi_alloc_cache atomically. So add the lockdep_assert_in_softirq() to assert when the running context is not in_softirq, in_softirq means softirq is serving or BH is disabled, which has a ambiguous semantics due to the BH disabled confusion, so add a comment to emphasize that. And the softirq context can be interrupted by hard IRQ or NMI context, lockdep_assert_in_softirq() need to assert about hard IRQ or NMI context too.

2020-11-26bridge: mrp: Implement LC mode for MRPHoratiu Vultur1-0/+1
Extend MRP to support LC mode(link check) for the interconnect port. This applies only to the interconnect ring. Opposite to RC mode(ring check) the LC mode is using CFM frames to detect when the link goes up or down and based on that the userspace will need to react. One advantage of the LC mode over RC mode is that there will be fewer frames in the normal rings. Because RC mode generates InTest on all ports while LC mode sends CFM frame only on the interconnect port. All 4 nodes part of the interconnect ring needs to have the same mode. And it is not possible to have running LC and RC mode at the same time on a node. Whenever the MIM starts it needs to detect the status of the other 3 nodes in the interconnect ring so it would send a frame called InLinkStatus, on which the clients needs to reply with their link status. This patch adds InLinkStatus frame type and extends existing rules on how to forward this frame.

Now that all the PHY drivers have been migrated to directly implement the generic .handle_interrupt() callback for a seamless support of shared IRQs and all the .config_inter() implementations clear any pending interrupts, we can safely remove the two callbacks. With this patch, phylib has a proper support for shared IRQs (and not just for multi-PHY devices. A PHY driver must implement both the .handle_interrupt() and .config_intr() callbacks for the IRQs to be actually used.

git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs David Howells says: ==================== rxrpc: Prelude to gssapi support Here are some patches that do some reorganisation of the security class handling in rxrpc to allow implementation of the RxGK security class that will allow AF_RXRPC to use GSSAPI-negotiated tokens and better crypto. The RxGK security class is not included in this patchset. It does the following things: (1) Add a keyrings patch to provide the original key description, as provided to add_key(), to the payload preparser so that it can interpret the content on that basis. Unfortunately, the rxrpc_s key type wasn't written to interpret its payload as anything other than a string of bytes comprising a key, but for RxGK, more information is required as multiple Kerberos enctypes are supported. (2) Remove the rxk5 security class key parsing. The rxk5 class never got rolled out in OpenAFS and got replaced with rxgk. (3) Support the creation of rxrpc keys with multiple tokens of different types. If some types are not supported, the ENOPKG error is suppressed if at least one other token's type is supported. (4) Punt the handling of server keys (rxrpc_s type) to the appropriate security class. (5) Organise the security bits in the rxrpc_connection struct into a union to make it easier to override for other classes. (6) Move some bits from core code into rxkad that won't be appropriate to rxgk. * tag 'rxrpc-next-20201123' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs: rxrpc: Ask the security class how much space to allow in a packet rxrpc: rxkad: Don't use pskb_pull() to advance through the response packet rxrpc: Organise connection security to use a union rxrpc: Don't reserve security header in Tx DATA skbuff rxrpc: Merge prime_packet_security into init_connection_security rxrpc: Fix example key name in a comment rxrpc: Ignore unknown tokens in key payload unless no known tokens rxrpc: Make the parsing of xdr payloads more coherent rxrpc: Allow security classes to give more info on server keys rxrpc: Don't leak the service-side session key to userspace rxrpc: Hand server key parsing off to the security class rxrpc: Split the server key type (rxrpc_s) into its own file rxrpc: Don't retain the server key in the connection rxrpc: Support keys with multiple authentication tokens rxrpc: List the held token types in the key description in /proc/keys rxrpc: Remove the rxk5 security class as it's now defunct keys: Provide the original description to the key preparser ==================== Link: https://lore.kernel.org/r/160616220405.830164.2239716599743995145.stgit@warthog.procyon.org.uk Signed-off-by: Jakub Kicinski <kuba@kernel.org>

2020-11-24net/packet: fix packet receive on L3 devices without visible hard headerEyal Birger1-0/+5
In the patchset merged by commit b9fcf0a0d826 ("Merge branch 'support-AF_PACKET-for-layer-3-devices'") L3 devices which did not have header_ops were given one for the purpose of protocol parsing on af_packet transmit path. That change made af_packet receive path regard these devices as having a visible L3 header and therefore aligned incoming skb->data to point to the skb's mac_header. Some devices, such as ipip, xfrmi, and others, do not reset their mac_header prior to ingress and therefore their incoming packets became malformed. Ideally these devices would reset their mac headers, or af_packet would be able to rely on dev->hard_header_len being 0 for such cases, but it seems this is not the case. Fix by changing af_packet RX ll visibility criteria to include the existence of a '.create()' header operation, which is used when creating a device hard header - via dev_hard_header() - by upper layers, and does not exist in these L3 devices. As this predicate may be useful in other situations, add it as a common dev_has_header() helper in netdevice.h.
