Currently, when a new MPTCP endpoint is added, the existing MPTCP sockets are not affected. This patch implements a new function mptcp_nl_add_subflow_or_signal_addr, invoked when an address is added from PM netlink. This function traverses the MPTCP sockets list and invokes mptcp_pm_create_subflow_or_signal_addr to try to create a subflow or signal an address for the newly added address, if local constraint allows that.

This patch drops the per-msk values add_addr_signal_max, add_addr_accept_max, local_addr_max and subflows_max fields in struct mptcp_pm_data, uses the pernet *_max values instead. And adds four new helpers to get the pernet *_max values separately.

Ido Schimmel says: ==================== Add notifications when route hardware flags change Routes installed to the kernel can be programmed to capable devices, in which case they are marked with one of two flags. RTM_F_OFFLOAD for routes that offload traffic from the kernel and RTM_F_TRAP for routes that trap packets to the kernel for processing (e.g., host routes). These flags are of interest to routing daemons since they would like to delay advertisement of routes until they are installed in hardware. This allows them to avoid packet loss or misrouted packets. Currently, routing daemons do not receive any notifications when these flags are changed, requiring them to poll the kernel tables for changes which is inefficient. This series addresses the issue by having the kernel emit RTM_NEWROUTE notifications whenever these flags change. The behavior is controlled by two sysctls (net.ipv4.fib_notify_on_flag_change and net.ipv6.fib_notify_on_flag_change) that default to 0 (no notifications). Note that even if route installation in hardware is improved to be more synchronous, these notifications are still of interest. For example, a multipath route can change from RTM_F_OFFLOAD to RTM_F_TRAP if its neighbours become invalid. A routing daemon can choose to withdraw / replace the route in that case. In addition, the deletion of a route from the kernel can prompt the installation of an identical route (already in kernel, with an higher metric) to hardware. For testing purposes, netdevsim is aligned to simulate a "real" driver that programs routes to hardware. Series overview: Patches #1-#2 align netdevsim to perform route programming in a non-atomic context Patches #3-#5 add sysctl to control IPv4 notifications Patches #6-#8 add sysctl to control IPv6 notifications Patch #9 extends existing fib tests to set sysctls before running tests Patch #10 adds test for fib notifications over netdevsim ==================== Link: https://lore.kernel.org/r/20210201194757.3463461-1-idosch@idosch.orgSigned-off-by: Jakub Kicinski <kuba@kernel.org>

Add test to check fib notifications behavior. The test checks route addition, route deletion and route replacement for both IPv4 and IPv6. When fib_notify_on_flag_change=0, expect single notification for route addition/deletion/replacement. When fib_notify_on_flag_change=1, expect: - two notification for route addition/replacement, first without RTM_F_TRAP and second with RTM_F_TRAP. - single notification for route deletion. $ ./fib_notifications.sh TEST: IPv4 route addition [ OK ] TEST: IPv4 route deletion [ OK ] TEST: IPv4 route replacement [ OK ] TEST: IPv6 route addition [ OK ] TEST: IPv6 route deletion [ OK ] TEST: IPv6 route replacement [ OK ] Signed-off-by: Amit Cohen <amcohen@nvidia.com> Signed-off-by: Ido Schimmel <idosch@nvidia.com> Reviewed-by: David Ahern <dsahern@kernel.org> Signed-off-by: Jakub Kicinski <kuba@kernel.org>

After installing a route to the kernel, user space receives an acknowledgment, which means the route was installed in the kernel, but not necessarily in hardware. The asynchronous nature of route installation in hardware can lead to a routing daemon advertising a route before it was actually installed in hardware. This can result in packet loss or mis-routed packets until the route is installed in hardware. It is also possible for a route already installed in hardware to change its action and therefore its flags. For example, a host route that is trapping packets can be "promoted" to perform decapsulation following the installation of an IPinIP/VXLAN tunnel. Emit RTM_NEWROUTE notifications whenever RTM_F_OFFLOAD/RTM_F_TRAP flags are changed. The aim is to provide an indication to user-space (e.g., routing daemons) about the state of the route in hardware. Introduce a sysctl that controls this behavior. Keep the default value at 0 (i.e., do not emit notifications) for several reasons: - Multiple RTM_NEWROUTE notification per-route might confuse existing routing daemons. - Convergence reasons in routing daemons. - The extra notifications will negatively impact the insertion rate. - Not all users are interested in these notifications. Move fib6_info_hw_flags_set() to C file because it is no longer a short function.

The next patch will emit notification when hardware flags are changed, in case that fib_notify_on_flag_change sysctl is set to 1. To know sysctl values, net struct is needed. This change is consistent with the IPv4 version, which gets 'net' struct as its first argument. Currently, the only callers of this function are mlxsw and netdevsim. Patch the callers to pass net.

Currently, netdevsim implements dummy FIB offload and marks notified routes with RTM_F_TRAP flag. netdevsim does not defer route notifications to a work queue because it does not need to program any hardware. Given that netdevsim's purpose is to both give an example implementation and allow developers to test their code, align netdevsim to a "real" hardware device driver like mlxsw and have it also perform the route "programming" in a non-atomic context. It will be used to test route flags notifications which will be added in the next patches. The following changes are needed when route handling is performed in WQ: - Handle the accounting in the main context, to be able to return an error for adding route when all the routes are used. For FIB_EVENT_ENTRY_REPLACE increase the counter before scheduling the delayed work, and in case that this event replaces an existing route, decrease the counter as part of the delayed work. - For IPv6, cannot use fen6_info->rt->fib6_siblings list because it might be changed during handling the delayed work. Save an array with the nexthops as part of fib6_event struct, and take a reference for each nexthop to prevent them from being freed while event is queued. - Change GFP_ATOMIC allocations to GFP_KERNEL. - Use single work item that is handling a list of ordered routes. Handling routes must be processed in the order they were submitted to avoid logical errors that could lead to unexpected failures.

When route is added/deleted, the appropriate counter is increased/decreased to maintain number of routes. User can limit the number of routes and then according to the appropriate counter, adding more routes than the limitation is forbidden. Currently, there is one lock which protects hashtable, list and accounting. Handling the counters will be performed from both atomic context and non-atomic context, while the hashtable and the list will be used only from non-atomic context and therefore will be protected by a separate lock. Protect accounting by using an atomic variable, so lock is not needed. v2: * Use atomic64_sub() in nsim_nexthop_account()'s error path Signed-off-by: Amit Cohen <amcohen@nvidia.com> Signed-off-by: Ido Schimmel <idosch@nvidia.com> Reviewed-by: David Ahern <dsahern@kernel.org> Signed-off-by: Jakub Kicinski <kuba@kernel.org>

Alex Elder says: ==================== net: ipa: don't disable NAPI in suspend This is version 2 of a series that reworks the order in which things happen during channel stop and suspend (and start and resume), in order to address a hang that has been observed during suspend. The introductory message on the first version of the series gave some history which is omitted here. The end result of this series is that we only enable NAPI and the I/O completion interrupt on a channel when we start the channel for the first time. And we only disable them when stopping the channel "for good." In other words, NAPI and the completion interrupt remain enabled while a channel is stopped for suspend. One comment on version 1 of the series suggested *not* returning early on success in a function, instead having both success and error paths return from the same point at the end of the function block. This has been addressed in this version. In addition, this version consolidates things a little bit, but the net result of the series is exactly the same as version 1 (with the exception of the return fix mentioned above). First, patch 6 in the first version was a small step to make patch 7 easier to understand. The two have been combined now. Second, previous version moved (and for suspend/resume, eliminated) I/O completion interrupt and NAPI disable/enable control in separate steps (patches). Now both are moved around together in patch 5 and 6, which eliminates the need for the final (NAPI-only) patch. I won't repeat the patch summaries provided in v1: https://lore.kernel.org/netdev/20210129202019.2099259-1-elder@linaro.org/ Many thanks to Willem de Bruijn for his thoughtful input. ==================== Link: https://lore.kernel.org/r/20210201172850.2221624-1-elder@linaro.orgSigned-off-by: Jakub Kicinski <kuba@kernel.org>

Transactions to send data for a network device can be allocated at any time up until the point the TX queue is stopped. It is possible for ipa_start_xmit() to be called in one context just before a the transmit queue is stopped in another. Update gsi_channel_trans_last() so that for TX channels the allocated and pending transaction lists are checked--in addition to the completed and polled lists--to determine the "last" transaction. This means any transaction that has been allocated before the TX queue is stopped will be allowed to complete before we conclude the channel is quiesced. Rework the function a bit to use a list pointer and gotos. Signed-off-by: Alex Elder <elder@linaro.org> Acked-by: Willem de Bruijn <willemb@google.com> Signed-off-by: Jakub Kicinski <kuba@kernel.org>

No completion interrupts will occur while an endpoint is suspended, nor when a channel has been stopped for suspend. So there's no need to disable the interrupt during suspend and re-enable it when resuming. Without any interrupts occurring, there is no need to disable/re-enable NAPI for channel suspend/resume either. We'll only enable NAPI and the interrupt when we first start the channel, and disable it again only when it's "really" stopped. To accomplish this, move the enable/disable calls out of __gsi_channel_start() and __gsi_channel_stop(), and into gsi_channel_start() and gsi_channel_stop() instead. Add a call to napi_synchronize() to gsi_channel_suspend(), to ensure NAPI polling is done before moving on.

Disable both the I/O completion interrupt and NAPI polling on a channel *after* we successfully stop it rather than before. This ensures a completion occurring just before the channel is stopped gets processed. Enable NAPI polling and the interrupt *before* starting a channel rather than after, to be symmetric. A stopped channel won't generate any completion interrupts anyway. Enable NAPI before the interrupt and disable it afterward.

Alex Elder authored
Create a new function that does most of the work of starting a channel. What's different is that it takes a flag indicating whether the channel should really be started or not. Create another new function __gsi_channel_stop() that behaves similarly. IPA v3.5.1 implements suspend using a special SUSPEND endpoint setting. If the endpoint is suspended when an I/O completes on the underlying GSI channel, a SUSPEND interrupt is generated. Newer versions of IPA do not implement the SUSPEND endpoint mode. Instead, endpoint suspend is implemented by simply stopping the underlying GSI channel. In this case, a completing I/O on a *stopped* channel causes the SUSPEND interrupt condition. These new functions put all activity related to starting or stopping a channel (including "thawing/freezing" the channel) in one place, whether or not the channel is actually started or stopped.

Avoid the assumption that ksize(kmalloc(S)) == ksize(kmalloc(S)): when cloning an skb, save and restore truesize after pskb_expand_head(). This can occur if the allocator decides to service an allocation of the same size differently (e.g. use a different size class, or pass the allocation on to KFENCE). Because truesize is used for bookkeeping (such as sk_wmem_queued), a modified truesize of a cloned skb may result in corrupt bookkeeping and relevant warnings (such as in sk_stream_kill_queues()).

With version 0 of the protocol it was legal to encode the 'Subflow Id' in the MP_PRIO suboption, to specify which subflow would change its 'Backup' flag. This has been removed from v1 specification: thus, according to RFC 8684 §3.3.8, the resulting 'Length' for MP_PRIO changed from 4 to 3 byte. Current Linux generates / parses MP_PRIO according to the old spec, using 'Length' equal to 4, and hardcoding 1 as 'Subflow Id'; RFC compliance can improve if we change 'Length' in other to become 3, leaving a 'Nop' after the MP_PRIO suboption. In this way the kernel will emit and accept *only* MP_PRIO suboptions that are compliant to version 1 of the MPTCP protocol. unpatched 5.11-rc kernel: [root@bottarga ~]# tcpdump -tnnr unpatched.pcap | grep prio reading from file unpatched.pcap, link-type LINUX_SLL (Linux cooked v1) dropped privs to tcpdump IP 10.0.3.2.48433 > 10.0.1.1.10006: Flags [.], ack 1, win 502, options [nop,nop,TS val 4032325513 ecr 1876514270,mptcp prio non-backup id 1,mptcp dss ack 14084896651682217737], length 0 patched 5.11-rc kernel: [root@bottarga ~]# tcpdump -tnnr patched.pcap | grep prio reading from file patched.pcap, link-type LINUX_SLL (Linux cooked v1) dropped privs to tcpdump IP 10.0.3.2.49735 > 10.0.1.1.10006: Flags [.], ack 1, win 502, options [nop,nop,TS val 1276737699 ecr 2686399734,mptcp prio non-backup,nop,mptcp dss ack 18433038869082491686], length 0 Changes since v2: - when accounting for option space, don't increment 'TCPOLEN_MPTCP_PRIO' and use 'TCPOLEN_MPTCP_PRIO_ALIGN' instead, thanks to Matthieu Baerts.
