2018-10-12net/ipv6: Add knob to skip DELROUTE message on device downDavid Ahern
Another difference between IPv4 and IPv6 is the generation of RTM_DELROUTE notifications when a device is taken down (admin down) or deleted. IPv4 does not generate a message for routes evicted by the down or delete; IPv6 does. A NOS at scale really needs to avoid these messages and have IPv4 and IPv6 behave similarly, relying on userspace to handle link notifications and evict the routes. At this point existing user behavior needs to be preserved. Since notifications are a global action (not per app) the only way to preserve existing behavior and allow the messages to be skipped is to add a new sysctl (net/ipv6/route/skip_notify_on_dev_down) which can be set to disable the notificatioons. IPv6 route code already supports the option to skip the message (it is used for multipath routes for example). Besides the new sysctl we need to pass the skip_notify setting through the generic fib6_clean and fib6_walk functions to fib6_clean_node and to set skip_notify on calls to __ip_del_rt for the addrconf_ifdown path.

Alexei Starovoitov says: ==================== pull-request: bpf-next 2018-10-08 The following pull-request contains BPF updates for your *net-next* tree. The main changes are: 1) sk_lookup_[tcp|udp] and sk_release helpers from Joe Stringer which allow BPF programs to perform lookups for sockets in a network namespace. This would allow programs to determine early on in processing whether the stack is expecting to receive the packet, and perform some action (eg drop, forward somewhere) based on this information. 2) per-cpu cgroup local storage from Roman Gushchin. Per-cpu cgroup local storage is very similar to simple cgroup storage except all the data is per-cpu. The main goal of per-cpu variant is to implement super fast counters (e.g. packet counters), which don't require neither lookups, neither atomic operations in a fast path. The example of these hybrid counters is in selftests/bpf/netcnt_prog.c 3) allow HW offload of programs with BPF-to-BPF function calls from Quentin Monnet 4) support more than 64-byte key/value in HW offloaded BPF maps from Jakub Kicinski 5) rename of libbpf interfaces from Andrey Ignatov. libbpf is maturing as a library and should follow good practices in library design and implementation to play well with other libraries. This patch set brings consistent naming convention to global symbols. 6) relicense libbpf as LGPL-2.1 OR BSD-2-Clause from Alexei Starovoitov to let Apache2 projects use libbpf 7) various AF_XDP fixes from Björn and Magnus ==================== Signed-off-by: David S.

2018-10-04rxrpc: Allow the reply time to be obtained on a client callDavid Howells
Allow the epoch value to be queried on a server connection. This is in the rxrpc header of every packet for use in routing and is derived from the client's state. It's also not supposed to change unless the client gets restarted. AFS can make use of this information to deduce whether a fileserver has been restarted because the fileserver makes client calls to the filesystem driver's cache manager to send notifications (ie. callback breaks) about conflicting changes from other clients. These convey the fileserver's own epoch value back to the filesystem. Signed-off-by: David Howells <dhowells@redhat.com>

One important change, not related to nested virtualization, is that the ability for the guest kernel to trap CPUID instructions (in Linux that's the ARCH_SET_CPUID arch_prctl) is now masked by default. This is because the feature is detected through an MSR; a very bad idea that Intel seems to like more and more.

Add KVM_CAP_MSR_PLATFORM_INFO so that userspace can disable guest access to reads of MSR_PLATFORM_INFO. Disabling access to reads of this MSR gives userspace the control to "expose" this platform-dependent information to guests in a clear way. As it exists today, guests that read this MSR would get unpopulated information if userspace hadn't already set it (and prior to this patch series, only the CPUID faulting information could have been populated). This existing interface could be confusing if guests don't handle the potential for incorrect/incomplete information gracefully (e.g. zero reported for base frequency).

git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue Jeff Kirsher says: ==================== 40GbE Intel Wired LAN Driver Updates 2018-09-18 This series contains changes to i40evf so that it becomes a more generic virtual function driver for current and future silicon. While doing the rename of i40evf to a more generic name of iavf, we also put the driver on a severe diet due to how much of the code was unneeded or was unused. The outcome is a lean and mean virtual function driver that continues to work on existing 40GbE (i40e) virtual devices and prepped for future supported devices, like the 100GbE (ice) virtual devices. This solves 2 issues we saw coming or were already present, the first was constant code duplication happening with i40e/i40evf, when much of the duplicate code in the i40evf was not used or was not needed. The second was to remove the future confusion of why future VF devices that were not considered "40GbE" only devices were supported by i40evf. The thought is that iavf will be the virtual function driver for all future devices, so it should have a "generic" name to properly represent that it is the VF driver for multiple generations of devices. The last patch in this series is unreleated to the iavf conversion and just has to do with a MODULE_LICENSE correction. Known Caveats: Existing user space configurations may have to change, but the module alias in patch 1 helps a bit here. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

Basically this is the simplest patch that gets the rename done and will be followed by other patches that rename the internal functions.

2018-09-14xen/balloon: add runtime control for scrubbing ballooned out pagesMarek Marczykowski-Górecki
Scrubbing pages on initial balloon down can take some time, especially in nested virtualization case (nested EPT is slow). When HVM/PVH guest is started with memory= significantly lower than maxmem=, all the extra pages will be scrubbed before returning to Xen. But since most of them weren't used at all at that point, Xen needs to populate them first (from populate-on-demand pool). In nested virt case (Xen inside KVM) this slows down the guest boot by 15-30s with just 1.5GB needed to be returned to Xen. Add runtime parameter to enable/disable it, to allow initially disabling scrubbing, then enable it back during boot (for example in initramfs). Such usage relies on assumption that a) most pages ballooned out during initial boot weren't used at all, and b) even if they were, very few secrets are in the guest at that time (before any serious userspace kicks in). Convert CONFIG_XEN_SCRUB_PAGES to CONFIG_XEN_SCRUB_PAGES_DEFAULT (also enabled by default), controlling default value for the new runtime switch.

2018-09-12KVM: s390: Make huge pages unavailable in ucontrol VMsJanosch Frank
We currently do not notify all gmaps when using gmap_pmdp_xchg(), due to locking constraints. This makes ucontrol VMs, which is the only VM type that creates multiple gmaps, incompatible with huge pages. Also we would need to hold the guest_table_lock of all gmaps that have this vmaddr maped to synchronize access to the pmd. ucontrol VMs are rather exotic and creating a new locking concept is no easy task. Hence we return EINVAL when trying to active KVM_CAP_S390_HPAGE_1M and report it as being not available when checking for it.
