This reverts commit a3ce2a21bb8969ae27917281244fa91bf5f286d7. Eric reported tests failings with commit. After digging into it, the bottom line is that the DAD sequence is not to be messed with.

2019-10-04Merge branch 'net-tls-separate-the-TLS-TOE-code-out'David S. Miller
Jakub Kicinski says: ==================== net/tls: separate the TLS TOE code out We have 3 modes of operation of TLS - software, crypto offload (Mellanox, Netronome) and TCP Offload Engine-based (Chelsio). The last one takes over the socket, like any TOE would, and is not really compatible with how we want to do things in the networking stack. Confusingly the name of the crypto-only offload mode is TLS_HW, while TOE-offload related functions use tls_hw_ as their prefix. Engineers looking to implement offload are also be faced with TOE artefacts like struct tls_device (while, again, CONFIG_TLS_DEVICE actually gates the non-TOE offload). To improve the clarity of the offload code move the TOE code into new files, and rename the functions and structures appropriately. Because TOE-offload takes over the socket, and makes no use of the TLS infrastructure in the kernel, the rest of the code (anything beyond the ULP setup handlers) do not have to worry about the mode == TLS_HW_RECORD case. The increase in code size is due to duplication of the full license boilerplate. Unfortunately original author (Dave Watson) seems unreachable :( ==================== Signed-off-by: David S.

2019-10-04Merge branch 'devlink-allow-devlink-instances-to-change-network-namespace'David S. Miller
Jiri Pirko says: ==================== devlink: allow devlink instances to change network namespace Devlink from the beginning counts with network namespaces, but the instances has been fixed to init_net. Implement change of network namespace as part of "devlink reload" procedure like this: $ ip netns add testns1 $ devlink/devlink dev reload netdevsim/netdevsim10 netns testns1 This command reloads device "netdevsim10" into network namespace "testns1". Note that "devlink reload" reinstantiates driver objects, effectively it reloads the driver instance, including possible hw reset etc. Newly created netdevices respect the network namespace of the parent devlink instance and according to that, they are created in target network namespace. Driver is able to refuse to be reloaded into different namespace. That is the case of mlx4 right now. FIB entries and rules are replayed during FIB notifier registration which is triggered during reload (driver instance init). FIB notifier is also registered to the target network namespace, that allows user to use netdevsim devlink resources to setup per-namespace limits of FIB entries and FIB rules. In fact, with multiple netdevsim instances in each network namespace, user might setup different limits. This maintains and extends current netdevsim resources behaviour. Patch 1 prepares netdevsim code for the follow-up changes in the patchset. It does not change the behaviour, only moves pet-init_netns accounting to netdevsim instance, which is also in init_netns. Patches 2-5 prepare the FIB notifier making it per-netns and to behave correctly upon error conditions. Patch 6 just exports a devlink_net helper so it can be used in drivers. Patches 7-9 do preparations in mlxsw driver. Patches 10-13 do preparations in netdevsim driver, namely patch 12 implements proper devlink reload where the driver instance objects are actually re-created as they should be. Patch 14 actually implements the possibility to reload into a different network namespace. Patch 15 adds needed selftests for devlink reload into namespace for netdevsim driver. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

2019-10-04net: fib_notifier: propagate possible error during fib notifier registrationJiri Pirko
Unlike events for registered notifier, during the registration, the errors that happened for the block being registered are not propagated up to the caller. Make sure the error is propagated for FIB rules and entries. Signed-off-by: Jiri Pirko <jiri@mellanox.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-10-04net: fib_notifier: make FIB notifier per-netnsJiri Pirko
Currently all users of FIB notifier only cares about events in init_net. Later in this patchset, users get interested in other namespaces too. However, for every registered block user is interested only about one namespace. Make the FIB notifier registration per-netns and avoid unnecessary calls of notifier block for other namespaces.

2019-10-04netdevsim: change fib accounting and limitations to be per-deviceJiri Pirko
Currently, the accounting is done per-namespace. However, devlink instance is always in init_net namespace for now, so only the accounting related to init_net is used. Limitations set using devlink resources are only considered for init_net. nsim_devlink_net() always returns init_net always. Make the accounting per-device. This brings no functional change. Per-device accounting has the same values as per-net. For a single netdevsim instance, the behaviour is exactly the same as before. When multiple netdevsim instances are created, each can have different limits. This is in prepare to implement proper devlink netns support. After that, the devlink instance which would exist in particular netns would account and limit that netns.

git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux Pull copy_struct_from_user() helper from Christian Brauner: "This contains the copy_struct_from_user() helper which got split out from the openat2() patchset. It is a generic interface designed to copy a struct from userspace. The helper will be especially useful for structs versioned by size of which we have quite a few. This allows for backwards compatibility, i.e. an extended struct can be passed to an older kernel, or a legacy struct can be passed to a newer kernel. For the first case (extended struct, older kernel) the new fields in an extended struct can be set to zero and the struct safely passed to an older kernel. The most obvious benefit is that this helper lets us get rid of duplicate code present in at least sched_setattr(), perf_event_open(), and clone3(). More importantly it will also help to ensure that users implementing versioning-by-size end up with the same core semantics. This point is especially crucial since we have at least one case where versioning-by-size is used but with slighly different semantics: sched_setattr(), perf_event_open(), and clone3() all do do similar checks to copy_struct_from_user() while rt_sigprocmask(2) always rejects differently-sized struct arguments. With this pull request we also switch over sched_setattr(), perf_event_open(), and clone3() to use the new helper" * tag 'copy-struct-from-user-v5.4-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux: usercopy: Add parentheses around assignment in test_copy_struct_from_user perf_event_open: switch to copy_struct_from_user() sched_setattr: switch to copy_struct_from_user() clone3: switch to copy_struct_from_user() lib: introduce copy_struct_from_user() helper
