The API should be backwards compatible so that if one s32 threshold value is passed, the old mechanism is enabled. The netlink event generated is the same in both cases. cfg80211 handles an arbitrary number of RSSI thresholds but drivers have to provide a method (set_cqm_rssi_range_config) that configures a range set by a high and a low value. Drivers have to call back when the RSSI goes out of that range and there's no additional event for each time the range is reconfigured as there was with the current one-threshold API. This method doesn't have a hysteresis parameter because there's no benefit to the cfg80211 code from having the hysteresis be handled by hardware/driver in terms of the number of wakeups. At the same time it would likely be less consistent between drivers if offloaded or done in the drivers.

But the same is not explicitly stated in FCC DFS requirement. Also, Pre-CAC requriements are not explicitly mentioned in FCC requirement. Current implementation in keeping DFS channel in available state is same as described in ETSI domain. For non-ETSI DFS domain, this patch gives a grace period of 2 seconds since the completion of successful CAC before moving the channel's DFS state to 'usable' from 'available' state. The same grace period is checked against the channel's dfs_state_entered timestamp while deciding if a DFS channel is available for operation. There is a new radar event, NL80211_RADAR_PRE_CAC_EXPIRED, reported when DFS channel is moved from available to usable state after the grace period. Also make sure the DFS channel state is reset to usable once the beaconing operation on that channel is brought down (like stop_ap, leave_ibss and leave_mesh) in non-ETSI domain.

The new attribute NFTA_HASH_TYPE has been included to support different types of hashing functions. Currently supported NFT_HASH_JENKINS through jhash and NFT_HASH_SYM through symhash. The main difference between both types are: - jhash requires an expression with sreg, symhash doesn't. - symhash supports modulus and offset, but not seed. Examples: nft add rule ip nat prerouting ct mark set jhash ip saddr mod 2 nft add rule ip nat prerouting ct mark set symhash mod 2 By default, jenkins hash will be used if no hash type is provided for compatibility reasons.

This allows us for bringing more clarity and determinism into the dump by making default pfifo qdiscs visible. We're not turning this on by default though, at it was deemed [2] too intrusive / unnecessary change of default behavior towards userspace. Instead, TCA_DUMP_INVISIBLE netlink attribute is introduced, which allows applications to request complete qdisc hierarchy dump, including the ones that have always been implicit/invisible. Singleton noop_qdisc stays invisible, as teaching the whole infrastructure about singletons would require quite some surgery with very little gain (seeing no qdisc or seeing noop qdisc in the dump is probably setting the same user expectation).

This patch introduces new PERF_RECORD_NAMESPACES event for recording namespaces related info. By recording info for every namespace, it is left to userspace to take a call on the definition of a container and trace containers by updating perf tool accordingly. Each namespace has a combination of device and inode numbers. Though every namespace has the same device number currently, that may change in future to avoid the need for a namespace of namespaces. Considering such possibility, record both device and inode numbers separately for each namespace.

Add a new optional LWT attribute, MPLS_IPTUNNEL_TTL, which allows the TTL to be set in the resulting MPLS packet, with the value of 0 having the semantics of enabling propagation of the TTL from the IP header (i.e. non-zero values disable propagation). Also allow the configuration to be overridden globally by reusing the same sysctl to control whether the TTL is propagated from IP packets into the MPLS header. If the per-LWT attribute is set then it overrides the global configuration. If the TTL isn't propagated then a default TTL value is used which can be configured via a new sysctl, "net.mpls.default_ttl". This is kept separate from the configuration of whether IP TTL propagation is enabled as it can be used in the future when non-IP payloads are supported (i.e. where there is no payload TTL that can be propagated).

The description of PPL is added to the documentation. More details can be found in the comments in raid5-ppl.c. Attach a page for holding the partial parity data to stripe_head. Allocate it only if mddev has the MD_HAS_PPL flag set. Partial parity is the xor of not modified data chunks of a stripe and is calculated as follows: - reconstruct-write case: xor data from all not updated disks in a stripe - read-modify-write case: xor old data and parity from all updated disks in a stripe Implement it using the async_tx API and integrate into raid_run_ops(). It must be called when we still have access to old data, so do it when STRIPE_OP_BIODRAIN is set, but before ops_run_prexor5(). The result is stored into sh->ppl_page. Partial parity is not meaningful for full stripe write and is not stored in the log or used for recovery, so don't attempt to calculate it when stripe has STRIPE_FULL_WRITE. Put the PPL metadata structures to md_p.h because userspace tools (mdadm) will also need to read/write PPL. Warn about using PPL with enabled disk volatile write-back cache for now. It can be removed once disk cache flushing before writing PPL is implemented.

The Aspeed BMC family which is what is used on OpenPOWER machines and a number of x86 as well is typically connected to the host via an LPC (Low Pin Count) bus (among others). The LPC bus is an ISA bus on steroids. It's generally used by the BMC chip to provide the host with access to the system flash (via MEM/FW cycles) that contains the BIOS or other host firmware along with a number of SuperIO-style IOs (via IO space) such as UARTs, IPMI controllers. On the BMC chip side, this is all configured via a bunch of registers whose content is related to a given policy of what devices are exposed at a per system level, which is system/vendor specific, so we don't want to bolt that into the BMC kernel. This started with a need to provide something nicer than /dev/mem for user space to configure these things. One important aspect of the configuration is how the MEM/FW space is exposed to the host (ie, the x86 or POWER). Some registers in that bridge can define a window remapping all or portion of the LPC MEM/FW space to a portion of the BMC internal bus, with no specific limits imposed in HW. I think it makes sense to ensure that this window is configured by a kernel driver that can apply some serious sanity checks on what it is configured to map. In practice, user space wants to control this by flipping the mapping between essentially two types of portions of the BMC address space: - The flash space. This is a region of the BMC MMIO space that more/less directly maps the system flash (at least for reads, writes are somewhat more complicated). - One (or more) reserved area(s) of the BMC physical memory. The latter is needed for a number of things, such as avoiding letting the host manipulate the innards of the BMC flash controller via some evil backdoor, we want to do flash updates by routing the window to a portion of memory (under control of a mailbox protocol via some separate set of registers) which the host can use to write new data in bulk and then request the BMC to flash it. There are other uses, such as allowing the host to boot from an in-memory flash image rather than the one in flash (very handy for continuous integration and test, the BMC can just download new images). It is important to note that due to the way the Aspeed chip lets the kernel configure the mapping between host LPC addresses and BMC ram addresses the offset within the window must be a multiple of size. Not doing so will fragment the accessible space rather than simply moving 'zero' upwards. This is caused by the nature of HICR8 being a mask and the way host LPC addresses are translated.

The system call takes two arguments, a command and pointer to a guarded storage control block: s390_guarded_storage(int command, struct gs_cb *gs_cb); The second argument is relevant only for the GS_SET_BC_CB command. The commands in detail: 0 - GS_ENABLE Enable the guarded storage facility for the current task. The initial content of the guarded storage control block will be all zeros. After the enablement the user space code can use load-guarded-storage-controls instruction (LGSC) to load an arbitrary control block. While a task is enabled the kernel will save and restore the current content of the guarded storage registers on context switch. 1 - GS_DISABLE Disables the use of the guarded storage facility for the current task. The kernel will cease to save and restore the content of the guarded storage registers, the task specific content of these registers is lost. 2 - GS_SET_BC_CB Set a broadcast guarded storage control block. This is called per thread and stores a specific guarded storage control block in the task struct of the current task. This control block will be used for the broadcast event GS_BROADCAST. 3 - GS_CLEAR_BC_CB Clears the broadcast guarded storage control block. The guarded- storage control block is removed from the task struct that was established by GS_SET_BC_CB. 4 - GS_BROADCAST Sends a broadcast to all thread siblings of the current task. Every sibling that has established a broadcast guarded storage control block will load this control block and will be enabled for guarded storage. The broadcast guarded storage control block is used up, a second broadcast without a refresh of the stored control block with GS_SET_BC_CB will not have any effect.

This is actually wrong since these encodings use limited range quantization, but accept values outside of the limited range. This makes sense since for values within the limited range it behaves exactly the same as BT.601 or Rec. 709. The only difference is that with the xvYCC encodings the values outside of the limited range also produce value colors. Talking to people who know a lot more about this than I do made me realize that mapping xvYCC to full range quantization was wrong, so this patch corrects this and also improves the documentation. These formats are very rare, and since the formula for decoding these Y'CbCr encodings is actually fixed and independent of the quantization field value it is safe to make this change. The main advantage is that keeps the V4L2 specification in sync with the corresponding colorspace, HDMI and CEA861 standards when it comes to these xvYCC formats.

While the sample action in the datpath has the matching semantics, its implementation is only optimized for its original use. Specifically, there are two limitation: First, there is a 3 level of nesting restriction, enforced at the flow downloading time. This limit turns out to be too restrictive for the 'clone' use case. Second, the implementation avoid recursive call only if the sample action list has a single userspace action. The main optimization implemented in this series removes the static nesting limit check, instead, implement the run time recursion limit check, and recursion avoidance similar to that of the 'recirc' action. This optimization solve both #1 and #2 issues above. One related optimization attempts to avoid copying flow key as long as the actions enclosed does not change the flow key. The detection is performed only once at the flow downloading time. Another related optimization is to rewrite the action list at flow downloading time in order to save the fast path from parsing the sample action list in its original form repeatedly.

This commit adds a new sysctl accept_ra_rt_info_min_plen that defines the minimum acceptable prefix length of Route Information Options. The new sysctl is intended to be used together with accept_ra_rt_info_max_plen to configure a range of acceptable prefix lengths. It is useful to prevent misconfigurations from unintentionally blackholing too much of the IPv6 address space (e.g., home routers announcing RIOs for fc00::/7, which is incorrect).

The first outer_map type BPF_MAP_TYPE_ARRAY_OF_MAPS is also added in this patch. The next patch will introduce a hash of maps type. Any bpf map type can be acted as an inner_map. The exception is BPF_MAP_TYPE_PROG_ARRAY because the extra level of indirection makes it harder to verify the owner_prog_type and owner_jited. Multi-level map-in-map is not supported (i.e. map->map is ok but not map->map->map). When adding an inner_map to an outer_map, it currently checks the map_type, key_size, value_size, map_flags, max_entries and ops. The verifier also uses those map's properties to do static analysis. map_flags is needed because we need to ensure BPF_PROG_TYPE_PERF_EVENT is using a preallocated hashtab for the inner_hash also. ops and max_entries are needed to generate inlined map-lookup instructions. For simplicity reason, a simple '==' test is used for both map_flags and max_entries. The equality of ops is implied by the equality of map_type. During outer_map creation time, an inner_map_fd is needed to create an outer_map. However, the inner_map_fd's life time does not depend on the outer_map. The inner_map_fd is merely used to initialize the inner_map_meta of the outer_map. Also, for the outer_map: * It allows element update and delete from syscall * It allows element lookup from bpf_prog The above is similar to the current fd_array pattern.

BPF_MAP_TYPE_HASH_OF_MAPS is added. A map-in-map contains a pointer to another map and lets call this pointer 'inner_map_ptr'. Notes on deleting inner_map_ptr from a hash map: 1. For BPF_F_NO_PREALLOC map-in-map, when deleting an inner_map_ptr, the htab_elem itself will go through a rcu grace period and the inner_map_ptr resides in the htab_elem. 2. For pre-allocated htab_elem (!BPF_F_NO_PREALLOC), when deleting an inner_map_ptr, the htab_elem may get reused immediately. This situation is similar to the existing prealloc-ated use cases. However, the bpf_map_fd_put_ptr() calls bpf_map_put() which calls inner_map->ops->map_free(inner_map) which will go through a rcu grace period (i.e. all bpf_map's map_free currently goes through a rcu grace period). Hence, the inner_map_ptr is still safe for the rcu reader side. This patch also includes BPF_MAP_TYPE_HASH_OF_MAPS to the check_map_prealloc() in the verifier. preallocation is a must for BPF_PROG_TYPE_PERF_EVENT. Hence, even we don't expect heavy updates to map-in-map, enforcing BPF_F_NO_PREALLOC for map-in-map is impossible without disallowing BPF_PROG_TYPE_PERF_EVENT from using map-in-map first.

If we want to place ourselves on the SGSN side of the tunnel, then we want to be identifying PDP contexts based on _source_ address. Let it be noted that in a "real" configuration this module would never be used: the SGSN normally does not see IP packets as input. The justification for this functionality is for PGW load-testing applications where the input to the SGSN is locally generally IP traffic. This patch adds a "role" argument at GTP-link creation time to specify whether we are on the GGSN or SGSN side of the tunnel; this flag is then used to determine which part of the IP packet to use in determining the PDP context.

The codes available are: - KVM_VM_MIPS_TE = 0 This is the current value expected from the user, and will create a VM using trap & emulate in user mode, confined to the user mode address space. This may in future become unavailable if the kernel is only configured to support VZ, in which case the EINVAL error will be returned and KVM_CAP_MIPS_TE won't be available even though KVM_CAP_MIPS_VZ is. - KVM_VM_MIPS_VZ = 1 This can be provided when the KVM_CAP_MIPS_VZ capability is available to create a VM using VZ, with a fully virtualized guest virtual address space. If VZ support is unavailable in the kernel, the EINVAL error will be returned (although old kernels without the KVM_CAP_MIPS_VZ capability may well succeed and create a trap & emulate VM). This is designed to allow the desired implementation (T&E vs VZ) to be potentially chosen at runtime rather than being fixed in the kernel configuration.

Generic protocol headers like IPv4 can be shared between drivers. Each driver can add local headers. Field - part of a header. Can represent protocol field or specific ASIC metadata field. Hardware special metadata fields can be mapped to different resources, for example switch ASIC ports can have internal number which from the systems point of view is mapped to netdeivce ifindex. Match - represent specific match rule. Can describe match on specific field or header. The header index should be specified as well in order to support several header instances of the same type (tunneling). Action - represents specific action rule. Actions can describe operations on specific field values for example like set, increment, etc. And header operation like add and delete. Value - represents value which can be associated with specific match or action. Table - represents a hardware block which can be described with match/ action behavior. The match/action can be done on the packets data or on the internal metadata that it gathered along the packets traversal throw the pipeline which is vendor specific and should be exported in order to provide understanding of ASICs behavior. Entry - represents single record in a specific table. The entry is identified by specific combination of values for match/action.

Despite availability of user space bpf interpreters the kernel is the ultimate authority and execution environment. Current test frameworks for TC include creation of netns, veth, qdiscs and use of various packet generators just to test functionality of a bpf program. XDP testing is even more complicated, since qemu needs to be started with gro/gso disabled and precise queue configuration, transferring of xdp program from host into guest, attaching to virtio/eth0 and generating traffic from the host while capturing the results from the guest. Moreover analyzing performance bottlenecks in XDP program is impossible in virtio environment, since cost of running the program is tiny comparing to the overhead of virtio packet processing, so performance testing can only be done on physical nic with another server generating traffic. Furthermore ongoing changes to user space control plane of production applications cannot be run on the test servers leaving bpf programs stubbed out for testing. Last but not least, the upstream llvm changes are validated by the bpf backend testsuite which has no ability to test the code generated. To improve this situation introduce BPF_PROG_TEST_RUN command to test and performance benchmark bpf programs. Joint work with Daniel Borkmann.

This functionality was only available using internal kernel APIs. With the KEYCTL_RESTRICT_KEYRING command existing keyrings can be configured to check the content of keys before they are linked, and then allow or disallow linkage of that key to the keyring. To restrict a keyring, call: keyctl(KEYCTL_RESTRICT_KEYRING, key_serial_t keyring, const char *type, const char *restriction) where 'type' is the name of a registered key type and 'restriction' is a string describing how key linkage is to be restricted. The restriction option syntax is specific to each key type.

The input to the KDF is defined as (DH shared secret || other information). The value for the "other information" is to be provided by the caller. The KDF is implemented using the hash support from the kernel crypto API. The implementation uses the symmetric hash support as the input to the hash operation is usually very small. The caller is allowed to specify the hash name that he wants to use to derive the key material allowing the use of all supported hashes provided with the kernel crypto API. As the KDF implements the proper truncation of the DH shared secret to the requested size, this patch fills the caller buffer up to its size. The patch is tested with a new test added to the keyutils user space code which uses a CAVS test vector testing the compliance with SP800-56A.

We can either handle them all using hardware acceleration through the vgic or we can emulate a gic in user space and only drive CPU IRQ pins from there. Unfortunately, when driving IRQs from user space, we never tell user space about events from devices emulated inside the kernel, which may result in interrupt line state changes, so we lose out on for example timer and PMU events if we run with user space gic emulation. Define an ABI to publish such device output levels to userspace.

Currently, there are four possible states of an skb wrt. conntrack. 1. No conntrack attached, ct is NULL. 2. Normal (kmem cache allocated) ct attached. 3. a template (kmalloc'd), not in any hash tables at any point in time 4. the 'untracked' conntrack, a percpu nf_conn object, tagged via IPS_UNTRACKED_BIT in ct->status. Untracked is supposed to be identical to case 1. It exists only so users can check -m conntrack --ctstate UNTRACKED vs. -m conntrack --ctstate INVALID e.g. attempts to set connmark on INVALID or UNTRACKED conntracks is supposed to be a no-op. Thus currently we need to check ct == NULL || nf_ct_is_untracked(ct) in a lot of places in order to avoid altering untracked objects. The other consequence of the percpu untracked object is that all -j NOTRACK (and, later, kfree_skb of such skbs) result in an atomic op (inc/dec the untracked conntracks refcount). This adds a new kernel-private ctinfo state, IP_CT_UNTRACKED, to make the distinction instead. The (few) places that care about packet invalid (ct is NULL) vs. packet untracked now need to test ct == NULL vs. ctinfo == IP_CT_UNTRACKED, but all other places can omit the nf_ct_is_untracked() check.

The other problem is we leave a userspace app sitting in it's syscall until the device disconnects, which is less than ideal. This patch introduces a netlink interface for adding and disconnecting nbd devices. This has the benefits of being easily extendable without breaking older userspace applications, and allows us to configure a nbd device without leaving a userspace app sitting waiting for the device to disconnect. With this interface we also gain the ability to configure more devices than are preallocated at insmod time. We also have gained the ability to not specify a particular device and be provided one for us so that userspace doesn't need to find a free device to configure.

For this to work correctly on big endian platforms, we need a big-endian definition for the bitfields. Currently on a big endian system, if a user requests PERF_SAMPLE_DATA_SRC (perf report -d), they will get the default value from perf_sample_data_init(), which is PERF_MEM_NA. The value for PERF_MEM_NA is constructed using shifts: /* TLB access */ #define PERF_MEM_TLB_NA 0x01 /* not available */ ... #define PERF_MEM_TLB_SHIFT 26 #define PERF_MEM_S(a, s) \ (((__u64)PERF_MEM_##a##_##s) << PERF_MEM_##a##_SHIFT) #define PERF_MEM_NA (PERF_MEM_S(OP, NA) |\ PERF_MEM_S(LVL, NA) |\ PERF_MEM_S(SNOOP, NA) |\ PERF_MEM_S(LOCK, NA) |\ PERF_MEM_S(TLB, NA)) Which works out as: ((0x01 << 0) | (0x01 << 5) | (0x01 << 19) | (0x01 << 24) | (0x01 << 26)) Which means the PERF_MEM_NA value comes out of the kernel as 0x5080021 in CPU endian. But then in the perf tool, the code uses the bitfields to inspect the value, and currently the bitfields are defined using little endian ordering. So eg. in perf_mem__tlb_scnprintf() we see: data_src->val = 0x5080021 op = 0x0 lvl = 0x0 snoop = 0x0 lock = 0x0 dtlb = 0x0 rsvd = 0x5080021 Because of the way the perf tool code is written this is still displayed to the user as "N/A", so there is no bug visible at the UI level. Currently there are no big endian architectures which export a meaningful value (ie. other than PERF_MEM_NA), so the extent of the bug on big endian platforms is that the PERF_MEM_NA value is exported incorrectly as described above. Subsequent patches will add support on big endian powerpc for populating the data source value. This patch does a minimal fix of adding big endian definition of the bitfields to match the values that are already exported by the kernel on big endian. And it makes no change on little endian.

This adds H_PUT_TCE/H_PUT_TCE_INDIRECT/H_STUFF_TCE handlers to KVM. KVM tries to handle a TCE request in the real mode, if failed it passes the request to the virtual mode to complete the operation. If it a virtual mode handler fails, the request is passed to the user space; this is not expected to happen though. To avoid dealing with page use counters (which is tricky in real mode), this only accelerates SPAPR TCE IOMMU v2 clients which are required to pre-register the userspace memory. The very first TCE request will be handled in the VFIO SPAPR TCE driver anyway as the userspace view of the TCE table (iommu_table::it_userspace) is not allocated till the very first mapping happens and we cannot call vmalloc in real mode. If we fail to update a hardware IOMMU table unexpected reason, we just clear it and move on as there is nothing really we can do about it - for example, if we hot plug a VFIO device to a guest, existing TCE tables will be mirrored automatically to the hardware and there is no interface to report to the guest about possible failures. This adds new attribute - KVM_DEV_VFIO_GROUP_SET_SPAPR_TCE - to the VFIO KVM device. It takes a VFIO group fd and SPAPR TCE table fd and associates a physical IOMMU table with the SPAPR TCE table (which is a guest view of the hardware IOMMU table). The iommu_table object is cached and referenced so we do not have to look up for it in real mode. This does not implement the UNSET counterpart as there is no use for it - once the acceleration is enabled, the existing userspace won't disable it unless a VFIO container is destroyed; this adds necessary cleanup to the KVM_DEV_VFIO_GROUP_DEL handler. This advertises the new KVM_CAP_SPAPR_TCE_VFIO capability to the user space. This adds real mode version of WARN_ON_ONCE() as the generic version causes problems with rcu_sched. Since we testing what vmalloc_to_phys() returns in the code, this also adds a check for already existing vmalloc_to_phys() call in kvmppc_rm_h_put_tce_indirect(). This finally makes use of vfio_external_user_iommu_id() which was introduced quite some time ago and was considered for removal. Tests show that this patch increases transmission speed from 220MB/s to 750..1020MB/s on 10Gb network (Chelsea CXGB3 10Gb ethernet card).

Tsirkin" Date: Fri, 21 Apr 2017 12:27:17 +0200 Subject: kvm: better MWAIT emulation for guests Guests that are heavy on futexes end up IPI'ing each other a lot. That can lead to significant slowdowns and latency increase for those guests when running within KVM. If only a single guest is needed on a host, we have a lot of spare host CPU time we can throw at the problem. Modern CPUs implement a feature called "MWAIT" which allows guests to wake up sleeping remote CPUs without an IPI - thus without an exit - at the expense of never going out of guest context. The decision whether this is something sensible to use should be up to the VM admin, so to user space. We can however allow MWAIT execution on systems that support it properly hardware wise. This patch adds a CAP to user space and a KVM cpuid leaf to indicate availability of native MWAIT execution. With that enabled, the worst a guest can do is waste as many cycles as a "jmp ." would do, so it's not a privilege problem. We consciously do *not* expose the feature in our CPUID bitmap, as most people will want to benefit from sleeping vCPUs to allow for over commit. Reported-by: "Gabriel L.

Having access to skb->napi_id is useful for per RX queue listener siloing, f.e. in combination with SO_ATTACH_REUSEPORT_EBPF and when busy polling is used, meaning SO_REUSEPORT enabled listeners can then select the corresponding socket at SYN time already [1]. The skb is marked via skb_mark_napi_id() early in the receive path (e.g., napi_gro_receive()). Currently, sockets can only use SO_INCOMING_NAPI_ID from 6d4339028b35 ("net: Introduce SO_INCOMING_NAPI_ID") as a socket option to look up the NAPI ID associated with the queue for steering, which requires a prior sk_mark_napi_id() after the socket was looked up. Semantics for the __sk_buff napi_id access are similar, meaning if skb->napi_id is < MIN_NAPI_ID (e.g. outgoing packets using sender_cpu), then an invalid napi_id of 0 is returned to the program, otherwise a valid non-zero napi_id.

Andrey's syzkaller program passes rtmsg.rtmsg_flags with the RTF_PCPU bit set. Flags passed to the kernel are blindly copied to the allocated rt6_info by ip6_route_info_create making a newly inserted route appear as though it is a per-cpu route. ip6_rt_cache_alloc sees the flag set and expects rt->dst.from to be set - which it is not since it is not really a per-cpu copy. The subsequent call to __ip6_dst_alloc then generates the fault. Fix by checking for the flag and failing with EINVAL.

Fanout uses a per net global namespace. A process that intends to create a new fanout group can accidentally join an existing group. It is not possible to detect this. Add socket option PACKET_FANOUT_FLAG_UNIQUEID. When specified the supplied fanout group id must be set to 0, and the kernel chooses an id that is not already in use. This is an ephemeral flag so that other sockets can be added to this group using setsockopt, but NOT specifying this flag. The current getsockopt(..., PACKET_FANOUT, ...) can be used to retrieve the new group id. We assume that there are not a lot of fanout groups and that this is not a high frequency call. The method assigns ids starting at zero and increases until it finds an unused id. It keeps track of the last assigned id, and uses it as a starting point to find new ids.

Add a new optional conntrack action attribute OVS_CT_ATTR_EVENTMASK, which can be used in conjunction with the commit flag (OVS_CT_ATTR_COMMIT) to set the mask of bits specifying which conntrack events (IPCT_*) should be delivered via the Netfilter netlink multicast groups. Default behavior depends on the system configuration, but typically a lot of events are delivered. This can be very chatty for the NFNLGRP_CONNTRACK_UPDATE group, even if only some types of events are of interest. Netfilter core init_conntrack() adds the event cache extension, so we only need to set the ctmask value. However, if the system is configured without support for events, the setting will be skipped due to extension not being found.

So the non-atomic operation "ct->status |= status;" via ctnetlink becomes unsafe, and this may clear the IPS_DYING_BIT bit set by another CPU unexpectedly. For example: CPU0 CPU1 ctnetlink_change_status __nf_conntrack_find_get old = ct->status nf_ct_gc_expired - nf_ct_kill - test_and_set_bit(IPS_DYING_BIT new = old | status; - ct->status = new; <-- oops, _DYING_ is cleared! Now using a series of atomic bit operation to solve the above issue. Also note, user shouldn't set IPS_TEMPLATE, IPS_SEQ_ADJUST directly, so make these two bits be unchangable too. If we set the IPS_TEMPLATE_BIT, ct will be freed by nf_ct_tmpl_free, but actually it is alloced by nf_conntrack_alloc. If we set the IPS_SEQ_ADJUST_BIT, this may cause the NULL pointer deference, as the nfct_seqadj(ct) maybe NULL. Last, add some comments to describe the logic change due to the commit a963d710f367 ("netfilter: ctnetlink: Fix regression in CTA_STATUS processing"), which makes me feel a little confusing.

It is arguable that perhaps I should have required something like this as part of the initial XDP feature merge. I believe this is critical for two reasons: 1) Accessibility. More people can play with XDP with less dependencies. Yes I know we have XDP support in virtio_net, but that just creates another depedency for learning how to use this facility. I wrote this to make life easier for the XDP newbies. 2) As a model for what the expected semantics are. If there is a pure generic core implementation, it serves as a semantic example for driver folks adding XDP support. One thing I have not tried to address here is the issue of XDP_PACKET_HEADROOM, thanks to Daniel for spotting that. It seems incredibly expensive to do a skb_cow(skb, XDP_PACKET_HEADROOM) or whatever even if the XDP program doesn't try to push headers at all. I think we really need the verifier to somehow propagate whether certain XDP helpers are used or not. v5: - Handle both negative and positive offset after running prog - Fix mac length in XDP_TX case (Alexei) - Use rcu_dereference_protected() in free_netdev (kbuild test robot) v4: - Fix MAC header adjustmnet before calling prog (David Ahern) - Disable LRO when generic XDP is installed (Michael Chan) - Bypass qdisc et al. on XDP_TX and record the event (Alexei) - Do not perform generic XDP on reinjected packets (DaveM) v3: - Make sure XDP program sees packet at MAC header, push back MAC header if we do XDP_TX.

Levin" Date: Wed, 26 Apr 2017 14:50:00 +0100 Subject: uapi: change the type of struct statx_timestamp.tv_nsec to unsigned The comment asserting that the value of struct statx_timestamp.tv_nsec must be negative when statx_timestamp.tv_sec is negative, is wrong, as could be seen from the following example: #define _FILE_OFFSET_BITS 64 #include #include #include #include #include #include #include int main(void) { static const struct timespec ts[2] = { { .tv_nsec = UTIME_OMIT }, { .tv_sec = -2, .tv_nsec = 42 } }; assert(utimensat(AT_FDCWD, ".", ts, 0) == 0); struct stat st; assert(stat(".", &st) == 0); printf("st_mtim.tv_sec = %lld, st_mtim.tv_nsec = %lu\n", (long long) st.st_mtim.tv_sec, (unsigned long) st.st_mtim.tv_nsec); struct statx stx; assert(syscall(__NR_statx, AT_FDCWD, ".", 0, 0, &stx) == 0); printf("stx_mtime.tv_sec = %lld, stx_mtime.tv_nsec = %lu\n", (long long) stx.stx_mtime.tv_sec, (unsigned long) stx.stx_mtime.tv_nsec); return 0; } It expectedly prints: st_mtim.tv_sec = -2, st_mtim.tv_nsec = 42 stx_mtime.tv_sec = -2, stx_mtime.tv_nsec = 42 The more generic comment asserting that the value of struct statx_timestamp.tv_nsec might be negative is confusing to say the least. It contradicts both the struct stat.st_[acm]time_nsec tradition and struct timespec.tv_nsec requirements in utimensat syscall. If statx syscall ever returns a stx_[acm]time containing a negative tv_nsec that cannot be passed unmodified to utimensat syscall, it will cause an immense confusion. Fix this source of confusion by changing the type of struct statx_timestamp.tv_nsec from __s32 to __u32.

It allows broadcast as it was introduced specifically for unknown multicast flood control. But as broadcast is a special case of multicast, this may also need to be disabled. For this purpose, introduce a flag to disable the flooding of received l2 broadcasts. This approach is backwards compatible and provides flexibility in filtering for the desired packet types.

The fscrypt_key structure was already part of the kernel ABI, this change just makes it so programs no longer have to redeclare these structures (like e4crypt in e2fsprogs currently does). Note that we do not expose the other FS_*_KEY_SIZE constants as they are not necessary. Only XTS is supported for contents_encryption_mode, so currently FS_MAX_KEY_SIZE bytes of key material must always be passed to the kernel. This commit also removes __packed from fscrypt_key as it does not contain any implicit padding and does not refer to an on-disk structure.

The AVR32 architecture is not keeping up with the development of the kernel, and since it shares so much of the drivers with Atmel ARM SoC, it is starting to hinder these drivers to develop swiftly. Also, all AVR32 AP7 SoC processors are end of lifed from Atmel (now Microchip). Finally, the GCC toolchain is stuck at version 4.2.x, and has not received any patches since the last release from Atmel; 4.2.4-atmel.1.1.3.avr32linux.1. When building kernel v4.10, this toolchain is no longer able to properly link the network stack. Haavard and I have came to the conclusion that we feel keeping AVR32 on life support offers more obstacles for Atmel ARMs, than it gives joy to AVR32 users. I also suspect there are very few AVR32 users left today, if anybody at all.

When set, the verifier will enforce strict pointer alignment regardless of the setting of CONFIG_EFFICIENT_UNALIGNED_ACCESS. The verifier, in this mode, will also use a fixed value of "2" in place of NET_IP_ALIGN.

The intended model for generic XDP from b5cdae3291f7 ("net: Generic XDP") is, however, that only one out of the two can be present at once which is also indicated as such in the XDP netlink dump part. The main rationale for generic XDP is to ease accessibility (in case a driver does not yet have XDP support) and to generically provide a semantical model as an example for driver developers wanting to add XDP support. The generic XDP option for an XDP aware driver can still be useful for comparing and testing both implementations. However, it is not intended to have a second XDP processing stage or layer with exactly the same functionality of the first native stage. Only reason could be to have a partial fallback for future XDP features that are not supported yet in the native implementation and we probably also shouldn't strive for such fallback and instead encourage native feature support in the first place. Given there's currently no such fallback issue or use case, lets not go there yet if we don't need to. Therefore, change semantics for loading XDP and bail out if the user tries to load a generic XDP program when a native one is present and vice versa. Another alternative to bailing out would be to handle the transition from one flavor to another gracefully, but that would require to bring the device down, exchange both types of programs, and bring it up again in order to avoid a tiny window where a packet could hit both hooks. Given this complicates the logic for just a debugging feature in the native case, I went with the simpler variant. For the dump, remove IFLA_XDP_FLAGS that was added with b5cdae3291f7 and reuse IFLA_XDP_ATTACHED for indicating the mode. Dumping all or just a subset of flags that were used for loading the XDP prog is suboptimal in the long run since not all flags are useful for dumping and if we start to reuse the same flag definitions for load and dump, then we'll waste bit space. What we really just want is to dump the mode for now. Current IFLA_XDP_ATTACHED semantics are: nothing was installed (0), a program is running at the native driver layer (1). Thus, add a mode that says that a program is running at generic XDP layer (2). Applications will handle this fine in that older binaries will just indicate that something is attached at XDP layer, effectively this is similar to IFLA_XDP_FLAGS attr that we would have had modulo the redundancy.
