This value will be compared against GCD of all beaconing interfaces of matching combinations. If the driver doesn't advertise this value, the old behaviour where all beacon intervals must be identical is retained. If it is specified, then any beacon interval for an interface in the interface combination as well as the GCD of all active beacon intervals in the combination must be greater or equal to this value.

All callers have been audited for calls to alloc_etherdev* or ether_setup directly, which means they all have a valid dev->min_mtu and dev->max_mtu. Now eth_change_mtu prints out a netdev_warn about being deprecated, for the benefit of out-of-tree drivers that might be utilizing it. Of note, dvb_net.c actually had dev->mtu = 4096, while using eth_change_mtu, meaning that if you ever tried changing it's mtu, you couldn't set it above 1500 anymore. It's now getting dev->max_mtu also set to 4096 to remedy that. v2: fix up lantiq_etop, missed breakage due to drive not compiling on x86 CC: netdev@vger.kernel.org Signed-off-by: Jarod Wilson Signed-off-by: David S.

Zone information are reported as struct blk_zone. This implementation does not differentiate between host-aware and host-managed device models and is valid for both. Two functions are provided: blkdev_report_zones for discovering the zone configuration of a zoned block device, and blkdev_reset_zones for resetting the write pointer of sequential zones. The helper function blk_queue_zone_size and bdev_zone_size are also provided for, as the name suggest, obtaining the zone size (in 512B sectors) of the zones of the device.

Additionally, because static family IDs would never be reserved by the generic netlink code, using a relatively low ID would only work for built-in families that can be registered immediately after generic netlink is started, which is basically only the control family (apart from the workaround code, which I also had to add code for so it would reserve those IDs) Thus, anything other than GENL_ID_GENERATE is flawed and luckily not used except in the cases I mentioned. Move those workarounds into a few lines of code, and then get rid of GENL_ID_GENERATE entirely, making it more robust. Signed-off-by: Johannes Berg Signed-off-by: David S.

Endpoint's maxpacket is laid out in bits 10:0. For high-speed, high-bandwidth isochronous endpoints, bits 12:11 contain a multiplier to tell us how many transactions we want to try per uframe. This means that if we want an isochronous endpoint to issue 3 transfers of 1024 bytes per uframe, wMaxPacketSize should contain the value: 1024 | (2 << 11) or 5120 (0x1400). In order to make Host and Peripheral controller drivers' life easier, we're adding a helper which returns bits 12:11. Note that no care is made WRT to checking endpoint type and gadget's speed. That's left for drivers to handle.

Currently supports fetching output interface index/name and the rtm_type associated with an address. This can be used for adding path filtering. rtm_type is useful to e.g. enforce a strong-end host model where packets are only accepted if daddr is configured on the interface the packet arrived on. The fib expression is a native nftables alternative to the xtables addrtype and rp_filter matches. FIB result order for oif/oifname retrieval is as follows: - if packet is local (skb has rtable, RTF_LOCAL set, this will also catch looped-back multicast packets), set oif to the loopback interface. - if fib lookup returns an error, or result points to local, store zero result. This means '--local' option of -m rpfilter is not supported. It is possible to use 'fib type local' or add explicit saddr/daddr matching rules to create exceptions if this is really needed. - store result in the destination register. In case of multiple routes, search set for desired oif in case strict matching is requested. ipv4 and ipv6 behave fib expressions are supposed to behave the same.

If `mode inline' was specified instead of `mode encap', then the SRH would be directly inserted after the IPv6 header without outer encapsulation. The inline mode is only available if CONFIG_IPV6_SEG6_INLINE is enabled. This feature was made configurable because direct header insertion may break several mechanisms such as PMTUD or IPSec AH.

Two HMAC algorithms are supported: hmac(sha1) and hmac(sha256). In order to avoid dynamic memory allocation for each HMAC computation, a per-cpu ring buffer is allocated for this purpose. A new per-interface sysctl called seg6_require_hmac is added, allowing a user-defined policy for processing HMAC-signed SR-enabled packets. A value of -1 means that the HMAC field will always be ignored. A value of 0 means that if an HMAC field is present, its validity will be enforced (the packet is dropped is the signature is incorrect). Finally, a value of 1 means that any SR-enabled packet that does not contain an HMAC signature or whose signature is incorrect will be dropped. Signed-off-by: David Lebrun Signed-off-by: David S.

The picture aspect was chosen rather than the pixel aspect since 1) the CEA-861 standard uses picture aspect, and 2) pixel aspect ratio can become tricky when dealing with pixel repeat timings. While we don't support those yet at the moment, this might become necessary. And in that case using picture aspect ratio makes more sense. And converting picture aspect ratio to pixel aspect ratio is easy enough.

For example: if we have to watch only 4th, 5th and 6th byte from a 64 bit aligned address, we will have to use two slots to implement it currently. One slot will watch a half word at offset 4 and other a byte at offset 6. If we can have a watchpoint of length 3 then we can watch it with single slot as well.

This patch just adds a 'failfast' per-device flag which can be stored in v0.90 or v1.x metadata. The flag is not used yet but the intent is that it can be used for mirrored (raid1/raid10) arrays where low latency is more important than keeping all devices on-line. Setting the flag for a device effectively gives permission for that device to be marked as Faulty and excluded from the array on the first error. The underlying driver will be directed not to retry requests that result in failures. There is a proviso that the device must not be marked faulty if that would cause the array as a whole to fail, it may only be marked Faulty if the array remains functional, but is degraded. Failures on read requests will cause the device to be marked as Faulty immediately so that further reads will avoid that device. No attempt will be made to correct read errors by over-writing with the correct data. It is expected that if transient errors, such as cable unplug, are possible, then something in user-space will revalidate failed devices and re-add them when they appear to be working again.

On the API level, the target could be anything that has an fd in userspace, hence the name of the field in union bpf_attr is called 'target_fd'. When called with BPF_ATTACH_TYPE_CGROUP_INET_{E,IN}GRESS, the target is expected to be a valid file descriptor of a cgroup v2 directory which has the bpf controller enabled. These are the only use-cases implemented by this patch at this point, but more can be added. If a program of the given type already exists in the given cgroup, the program is swapped automically, so userspace does not have to drop an existing program first before installing a new one, which would otherwise leave a gap in which no program is attached. For more information on the propagation logic to subcgroups, please refer to the bpf cgroup controller implementation. The API is guarded by CAP_NET_ADMIN.

Currently we can instrument how long a particular application unit of data was queued in TCP by tracking SOF_TIMESTAMPING_TX_SOFTWARE and SOF_TIMESTAMPING_TX_SCHED. Having these sender chronograph stats exported simultaneously along with these timestamps allow further breaking down the various sender limitation. For example, a video server can tell if a particular chunk of video on a connection takes a long time to deliver because TCP was experiencing small receive window. It is not possible to tell before this patch without packet traces.

Since rules mangling layer 3 fields that are part of the pseudoheader may potentially convey any layer 4 packet, we have to deal with the layer 4 checksum adjustment using protocol specific code.

When both the features are enabled, both the BSSID and the local MAC address were getting same value causing Probe Request frames to go with unintended DA. Hence, this has been fixed by using a different NL80211_ATTR_BSSID attribute to set the specific BSSID (which was the more recent addition in cfg80211) for a scan. Backwards compatibility with old userspace software is maintained to some extent by allowing NL80211_ATTR_MAC to be used to set the specific BSSID when scanning without enabling random MAC address use. Scanning with random source MAC address was introduced by commit ad2b26abc157 ("cfg80211: allow drivers to support random MAC addresses for scan") and the issue was introduced with the addition of the second user for the same attribute in commit 818965d39177 ("cfg80211: Allow a scan request for a specific BSSID").

The virtio crypto device is a virtual cryptography device as well as a kind of virtual hardware accelerator for virtual machines. The encryption anddecryption requests are placed in the data queue and are ultimately handled by thebackend crypto accelerators. The second queue is the control queue used to create or destroy sessions for symmetric algorithms and will control some advanced features in the future. The virtio crypto device provides the following cryptoservices: CIPHER, MAC, HASH, and AEAD.

It encodes whether a packet was redirected by an act_mirred device and, if so, whether act_mirred was called on ingress or egress. Split it into separate fields. The information is needed by the special IFB loop, where packets are taken out of the normal path by act_mirred, forwarded to IFB, then reinjected at their original location (ingress or egress) by IFB. The IFB device cannot use skb->tc_at_ingress, because that may have been overwritten as the packet travels from act_mirred to ifb_xmit, when it passes through tc_classify on the IFB egress path. Cache this value in skb->tc_from_ingress. That field is valid only if a packet arriving at ifb_xmit came from act_mirred. Other packets can be crafted to reach ifb_xmit. These must be dropped. Set tc_redirected on redirection and drop all packets that do not have this bit set. Both fields are set only on cloned skbs in tc actions, so original packet sources do not have to clear the bit when reusing packets (notably, pktgen and octeon).

The Ethernet interface for this TCP-connection is not restricted to the Ethernet interface of a RoCE device. Any existing Ethernet interface belonging to the same physical net can be used, as long as there is a defined relation between the Ethernet interface and some RoCE devices. This relation is defined with the help of an identification string called "Physical Net ID" or short "pnet ID". Information about defined pnet IDs and their related Ethernet interfaces and RoCE devices is stored in the SMC-R pnet table. A pnet table entry consists of the identifying pnet ID and the associated network and IB device. This patch adds pnet table configuration support using the generic netlink message interface referring to network and IB device by their names. Commands exist to add, delete, and display pnet table entries, and to flush or display the entire pnet table. There are cross-checks to verify whether the ethernet interfaces or infiniband devices really exist in the system. If either device is not available, the pnet ID entry is not created. Loss of network devices and IB devices is also monitored; a pnet ID entry is removed when an associated network or IB device is removed.

Applications fill the random transmit address in the frame buffer in the NL80211_CMD_FRAME command. This can be used only with the drivers that indicate support for random local address by setting the new NL80211_EXT_FEATURE_MGMT_TX_RANDOM_TA and/or NL80211_EXT_FEATURE_MGMT_TX_RANDOM_TA_CONNECTED in ext_features. The driver needs to configure receive behavior to accept frames to the specified random address during the time the frame exchange is pending and such frames need to be acknowledged similarly to frames sent to the local permanent address when this random address functionality is not used.

The intended use cases are for debugging resp. introspection only for providing a stable "tag" over the instruction sequence that both kernel and user space can calculate independently. It's not usable at all for making a security relevant decision. So collisions where two different instruction sequences generate the same tag can happen, but ideally at a rather low rate. The "tag" will be dumped in hex and is short enough to introspect in tracepoints or kallsyms output along with other data such as stack trace, etc. Thus, this patch performs a rename into prog_tag and truncates the tag to a short output (64 bits) to make it obvious it's not collision-free. Should in future a hash or facility be needed with a security relevant focus, then we can think about requirements, constraints, etc that would fit to that situation. For now, rework the exposed parts for the current use cases as long as nothing has been released yet. Tested on x86_64 and s390x.

This is done through adding a new IFLA_STATS_AF_SPEC attribute under which address family attributes are nested and then the AF-specific attributes can be further nested. This follows the model of IFLA_AF_SPEC on RTM_*LINK messages and it has the advantage of presenting an easily extended hierarchy. The rtnl_af_ops structure is extended to provide AFs with the opportunity to fill and provide the size of their stats attributes. One alternative would have been to provide AFs with the ability to add attributes directly into the RTM_GETSTATS message without a nested hierarchy. I discounted this approach as it increases the rate at which the 32 attribute number space is used up and it makes implementation a little more tricky for stats dump resuming (at the moment the order in which attributes are added to the message has to match the numeric order of the attributes). Another alternative would have been to register per-AF RTM_GETSTATS handlers. I discounted this approach as I perceived a common use-case to be getting all the stats for an interface and this approach would necessitate multiple requests/dumps to retrieve them all.

In the absence of anything better, RFC2863 and RFC3813 are used for guidance for which stats to expose and the semantics of them. In particular rx_noroutes maps to in unknown protos in RFC2863. The stats are exposed to userspace via AF_MPLS attributes embedded in the IFLA_STATS_AF_SPEC attribute of RTM_GETSTATS messages. All the introduced fields are 64-bit, even error ones, to ensure no overflow with long uptimes. Per-CPU counters are used to avoid cache-line contention on the commonly used fields. The other fields have also been made per-CPU for code to avoid performance problems in error conditions on the assumption that on some platforms the cost of atomic operations could be more expensive than sending the packet (which is what would be done in the success case). If that's not the case, we could instead not use per-CPU counters for these fields. Only unicast and non-fragment are exposed at the moment, but other counters can be exposed in the future either by adding to the end of struct mpls_link_stats or by additional netlink attributes in the AF_MPLS IFLA_STATS_AF_SPEC nested attribute.

It provides a control interface, allowing userspace to export endpoints and an endpoint interface for each exposed endpoint. The implementation is based on prior art by Texas Instrument, Google, PetaLogix and was derived from a FreeRTOS performance statistics driver written by Michal Simek. The control interface provides a "create endpoint" ioctl, which is fed a name, source and destination address. The three values are used to create the endpoint, in a backend-specific way, and a rpmsg endpoint device is created - with the three parameters are available in sysfs for udev usage. E.g. to create an endpoint device for one of the Qualcomm SMD channel related to DIAG one would issue: struct rpmsg_endpoint_info info = { "DIAG_CNTL", 0, 0 }; int fd = open("/dev/rpmsg_ctrl0", O_RDWR); ioctl(fd, RPMSG_CREATE_EPT_IOCTL, &info); Each created endpoint device shows up as an individual character device in /dev, allowing permission to be controlled on a per-endpoint basis. The rpmsg endpoint will be created and destroyed following the opening and closing of the endpoint device, allowing rpmsg backends to open and close the physical channel, if supported by the wire protocol.

A typical use case is intercepting a file name during sys_open(). The current approach is: SEC("kprobe/sys_open") void bpf_sys_open(struct pt_regs *ctx) { char buf[PATHLEN]; // PATHLEN is defined to 256 bpf_probe_read(buf, sizeof(buf), ctx->di); /* consume buf */ } This is suboptimal because the size of the string needs to be estimated at compile time, causing more memory to be copied than often necessary, and can become more problematic if further processing on buf is done, for example by pushing it to userspace via bpf_perf_event_output(), since the real length of the string is unknown and the entire buffer must be copied (and defining an unrolled strnlen() inside the bpf program is a very inefficient and unfeasible approach). With the new helper, the code can easily operate on the actual string length rather than the buffer size: SEC("kprobe/sys_open") void bpf_sys_open(struct pt_regs *ctx) { char buf[PATHLEN]; // PATHLEN is defined to 256 int res = bpf_probe_read_str(buf, sizeof(buf), ctx->di); /* consume buf, for example push it to userspace via * bpf_perf_event_output(), but this time we can use * res (the string length) as event size, after checking * its boundaries. */ } Another useful use case is when parsing individual process arguments or individual environment variables navigating current->mm->arg_start and current->mm->env_start: using this helper and the return value, one can quickly iterate at the right offset of the memory area. The code changes simply leverage the already existent strncpy_from_unsafe() kernel function, which is safe to be called from a bpf program as it is used in bpf_trace_printk().

This is clearly wasteful if the cluster is large and there are only a few real destinations for the message being sent. In this commit we extend the eligibility of the newly introduced "replicast" transmit option. We now make it possible for a user to select which method he wants to be used, either as a mandatory setting via setsockopt(), or as a relative setting where we let the broadcast layer decide which method to use based on the ratio between cluster size and the message's actual number of destination nodes. In the latter case, a sending socket must stick to a previously selected method until it enters an idle period of at least 5 seconds. This eliminates the risk of message reordering caused by method change, i.e., when changes to cluster size or number of destinations would otherwise mandate a new method to be used.

This is done by copying the packet per host and changing the multicast destination MAC to a unicast one accordingly. multicast-to-unicast works on top of the multicast snooping feature of the bridge. Which means unicast copies are only delivered to hosts which are interested in it and signalized this via IGMP/MLD reports previously. This feature is intended for interface types which have a more reliable and/or efficient way to deliver unicast packets than broadcast ones (e.g. wifi).

This netlink channel can be used by tc, iptables, etc. and allow to standardize packet sampling in the kernel. For every sampled packet, the psample module adds the following metadata fields: PSAMPLE_ATTR_IIFINDEX - the packets input ifindex, if applicable PSAMPLE_ATTR_OIFINDEX - the packet output ifindex, if applicable PSAMPLE_ATTR_ORIGSIZE - the packet's original size, in case it has been truncated during sampling PSAMPLE_ATTR_SAMPLE_GROUP - the packet's sample group, which is set by the user who initiated the sampling. This field allows the user to differentiate between several samplers working simultaneously and filter packets relevant to him PSAMPLE_ATTR_GROUP_SEQ - sequence counter of last sent packet. The sequence is kept for each group PSAMPLE_ATTR_SAMPLE_RATE - the sampling rate used for sampling the packets PSAMPLE_ATTR_DATA - the actual packet bits The sampled packets are sent to the PSAMPLE_NL_MCGRP_SAMPLE multicast group. In addition, add the GET_GROUPS netlink command which allows the user to see the current sample groups, their refcount and sequence number. This command currently supports only netlink dump mode.

The sampling consists of choosing packets randomly and sampling them using the psample module. The user can configure the psample group number, the sampling rate and the packet's truncation (to save kernel-user traffic). Example: To sample ingress traffic from interface eth1, one may use the commands: tc qdisc add dev eth1 handle ffff: ingress tc filter add dev eth1 parent ffff: \ matchall action sample rate 12 group 4 Where the first command adds an ingress qdisc and the second starts sampling randomly with an average of one sampled packet per 12 packets on dev eth1 to psample group 4.

It might have been better if NS_GET_USERNS had returned an error if the supplied file descriptor referred to a user namespace, since it suggests that the caller may be confused. More particularly, if it had generated an error, then I wouldn't need the new ioctl() operation proposed here. (On the other hand, what I propose here may be more generally useful.) I would like to write code that discovers namespace relationships for the purpose of understanding the namespace setup on a running system. In particular, given a file descriptor (or pathname) for a namespace, N, I'd like to obtain the corresponding user namespace. Namespace N might be a user namespace (in which case my code would just use N) or a non-user namespace (in which case my code will use NS_GET_USERNS to get the user namespace associated with N). The problem is that there is no way to tell the difference by looking at the file descriptor (and if I try to use NS_GET_USERNS on an N that is a user namespace, I get the parent user namespace of N, which is not what I want). This patch therefore adds a new ioctl(), NS_GET_NSTYPE, which, given a file descriptor that refers to a user namespace, returns the namespace type (one of the CLONE_NEW* constants).

Prior to this patch, a client needs to replace the connect() call with sendto(MSG_FASTOPEN). This can be cumbersome for applications who want to use Fast Open: these socket operations are often done in lower layer libraries used by many other applications. Changing these libraries and/or the socket call sequences are not trivial. A more convenient approach is to perform Fast Open by simply enabling a socket option when the socket is created w/o changing other socket calls sequence: s = socket() create a new socket setsockopt(s, IPPROTO_TCP, TCP_FASTOPEN_CONNECT …); newly introduced sockopt If set, new functionality described below will be used. Return ENOTSUPP if TFO is not supported or not enabled in the kernel. connect() With cookie present, return 0 immediately. With no cookie, initiate 3WHS with TFO cookie-request option and return -1 with errno = EINPROGRESS. write()/sendmsg() With cookie present, send out SYN with data and return the number of bytes buffered. With no cookie, and 3WHS not yet completed, return -1 with errno = EINPROGRESS. No MSG_FASTOPEN flag is needed. read() Return -1 with errno = EWOULDBLOCK/EAGAIN if connect() is called but write() is not called yet. Return -1 with errno = EWOULDBLOCK/EAGAIN if connection is established but no msg is received yet. Return number of bytes read if socket is established and there is msg received. The new API simplifies life for applications that always perform a write() immediately after a successful connect(). Such applications can now take advantage of Fast Open by merely making one new setsockopt() call at the time of creating the socket. Nothing else about the application's socket call sequence needs to change. Signed-off-by: Wei Wang Acked-by: Eric Dumazet Acked-by: Yuchung Cheng Signed-off-by: David S.

The KVM_PPC_CONFIGURE_V3_MMU ioctl allows userspace to specify whether a guest will use the radix MMU or the HPT MMU, and to specify the size and location (in guest space) of the process table. The KVM_PPC_GET_RMMU_INFO ioctl gives userspace information about the radix MMU. It returns a list of supported radix tree geometries (base page size and number of bits indexed at each level of the radix tree) and the encoding used to specify the various page sizes for the TLB invalidate entry instruction. Initially, both capabilities return 0 and the ioctls return -EINVAL, until the necessary infrastructure for them to operate correctly is added.

It also adds definitions for two new VM ioctl()s to implement this extension, and documentation of the same. Note that, HPT resizing is already possible with KVM PR without kernel modification, since the HPT is managed within userspace (qemu). The capability defined here will only be set where an in-kernel implementation of resizing is necessary, i.e. for KVM HV. To determine if the userspace resize implementation can be used, it's necessary to check KVM_CAP_PPC_ALLOC_HTAB. Unfortunately older kernels incorrectly set KVM_CAP_PPC_ALLOC_HTAB even with KVM PR. If userspace it want to support resizing with KVM PR on such kernels, it will need a workaround.

Bruce Fields" Date: Tue, 3 Jan 2017 12:30:11 -0500 Subject: nfsd: opt in to labeled nfs per export Currently turning on NFSv4.2 results in 4.2 clients suddenly seeing the individual file labels as they're set on the server. This is not what they've previously seen, and not appropriate in may cases. (In particular, if clients have heterogenous security policies then one client's labels may not even make sense to another.) Labeled NFS should be opted in only in those cases when the administrator knows it makes sense. It's helpful to be able to turn 4.2 on by default, and otherwise the protocol upgrade seems free of regressions. So, default labeled NFS to off and provide an export flag to reenable it. Users wanting labeled NFS support on an export will henceforth need to: - make sure 4.2 support is enabled on client and server (as before), and - upgrade the server nfs-utils to a version supporting the new "security_label" export flag. - set that "security_label" flag on the export. This is commit may be seen as a regression to anyone currently depending on security labels. We believe those cases are currently rare. Reported-by: tibbs@math.uh.edu Signed-off-by: J.

Biederman" Date: Wed, 1 Feb 2017 06:06:16 +1300 Subject: fs: Better permission checking for submounts To support unprivileged users mounting filesystems two permission checks have to be performed: a test to see if the user allowed to create a mount in the mount namespace, and a test to see if the user is allowed to access the specified filesystem. The automount case is special in that mounting the original filesystem grants permission to mount the sub-filesystems, to any user who happens to stumble across the their mountpoint and satisfies the ordinary filesystem permission checks. Attempting to handle the automount case by using override_creds almost works. It preserves the idea that permission to mount the original filesystem is permission to mount the sub-filesystem. Unfortunately using override_creds messes up the filesystems ordinary permission checks. Solve this by being explicit that a mount is a submount by introducing vfs_submount, and using it where appropriate. vfs_submount uses a new mount internal mount flags MS_SUBMOUNT, to let sget and friends know that a mount is a submount so they can take appropriate action. sget and sget_userns are modified to not perform any permission checks on submounts. follow_automount is modified to stop using override_creds as that has proven problemantic. do_mount is modified to always remove the new MS_SUBMOUNT flag so that we know userspace will never by able to specify it. autofs4 is modified to stop using current_real_cred that was put in there to handle the previous version of submount permission checking. cifs is modified to pass the mountpoint all of the way down to vfs_submount. debugfs is modified to pass the mountpoint all of the way down to trace_automount by adding a new parameter. To make this change easier a new typedef debugfs_automount_t is introduced to capture the type of the debugfs automount function.

The caller has to have CAP_NET_ADMIN in the socket network namespace. Currently it is impossible to get a path and a mount point for a socket file. socket_diag reports address, device ID and inode number for unix sockets. An address can contain a relative path or a file may be moved somewhere. And these properties say nothing about a mount namespace and a mount point of a socket file. With the introduced ioctl, we can get a path by reading /proc/self/fd/X and get mnt_id from /proc/self/fdinfo/X. In CRIU we are going to use this ioctl to dump and restore unix socket.

It expects all forwarding information to be present in dst_metadata. This patch series enhances collect metadata mode to include the case where only vni is present in dst_metadata, and the vxlan driver can then use the rest of the forwarding information datbase to make forwarding decisions. There is no change to default COLLECT_METADATA behaviour. These changes only apply to COLLECT_METADATA when used with the bridging use-case with a special dst_metadata tunnel info flag (eg: where vxlan device is part of a bridge). For all this to work, the vxlan driver will need to now support a single fdb table hashed by mac + vni. This series essentially makes this happen. use-case and workflow: vxlan collect metadata device participates in bridging vlan to vn-segments. Bridge driver above the vxlan device, sends the vni corresponding to the vlan in the dst_metadata. vxlan driver will lookup forwarding database with (mac + vni) for the required remote destination information to forward the packet. Changes introduced by this patch: - allow learning and forwarding database state in vxlan netdev in COLLECT_METADATA mode. Current behaviour is not changed by default. tunnel info flag IP_TUNNEL_INFO_BRIDGE is used to support the new bridge friendly mode. - A single fdb table hashed by (mac, vni) to allow fdb entries with multiple vnis in the same fdb table - rx path already has the vni - tx path expects a vni in the packet with dst_metadata - prior to this series, fdb remote_dsts carried remote vni and the vxlan device carrying the fdb table represented the source vni. With the vxlan device now representing multiple vnis, this patch adds a src vni attribute to the fdb entry. The remote vni already uses NDA_VNI attribute. This patch introduces NDA_SRC_VNI netlink attribute to represent the src vni in a multi vni fdb table. iproute2 example (patched and pruned iproute2 output to just show relevant fdb entries): example shows same host mac learnt on two vni's. before (netdev per vni): $bridge fdb show | grep "00:02:00:00:00:03" 00:02:00:00:00:03 dev vxlan1001 dst 12.0.0.8 self 00:02:00:00:00:03 dev vxlan1000 dst 12.0.0.8 self after this patch with collect metadata in bridged mode (single netdev): $bridge fdb show | grep "00:02:00:00:00:03" 00:02:00:00:00:03 dev vxlan0 src_vni 1001 dst 12.0.0.8 self 00:02:00:00:00:03 dev vxlan0 src_vni 1000 dst 12.0.0.8 self Signed-off-by: Roopa Prabhu Signed-off-by: David S.

This breaks conntrackd's userland helpers because they operate on unconfirmed connections. Instead of returning -EBUSY if the user program asks to modify an unchangeable bit, simply ignore the change. Also, fix the logic so that user programs are allowed to clear the bits that they are allowed to change.

Note for marvell/mwifiex I pass 0 for the RSSI value because the new RSSI value is not available to the driver at the time of the cfg80211_cqm_rssi_notify call, but the driver queries the new value immediately after that, so it is actually available just a moment later if we wanted to defer caling cfg80211_cqm_rssi_notify until that moment.

Add the fields of the conntrack original direction 5-tuple to struct sw_flow_key. The new fields are initially marked as non-existent, and are populated whenever a conntrack action is executed and either finds or generates a conntrack entry. This means that these fields exist for all packets that were not rejected by conntrack as untrackable. The original tuple fields in the sw_flow_key are filled from the original direction tuple of the conntrack entry relating to the current packet, or from the original direction tuple of the master conntrack entry, if the current conntrack entry has a master. Generally, expected connections of connections having an assigned helper (e.g., FTP), have a master conntrack entry. The main purpose of the new conntrack original tuple fields is to allow matching on them for policy decision purposes, with the premise that the admissibility of tracked connections reply packets (as well as original direction packets), and both direction packets of any related connections may be based on ACL rules applying to the master connection's original direction 5-tuple. This also makes it easier to make policy decisions when the actual packet headers might have been transformed by NAT, as the original direction 5-tuple represents the packet headers before any such transformation. When using the original direction 5-tuple the admissibility of return and/or related packets need not be based on the mere existence of a conntrack entry, allowing separation of admission policy from the established conntrack state. While existence of a conntrack entry is required for admission of the return or related packets, policy changes can render connections that were initially admitted to be rejected or dropped afterwards. If the admission of the return and related packets was based on mere conntrack state (e.g., connection being in an established state), a policy change that would make the connection rejected or dropped would need to find and delete all conntrack entries affected by such a change. When using the original direction 5-tuple matching the affected conntrack entries can be allowed to time out instead, as the established state of the connection would not need to be the basis for packet admission any more. It should be noted that the directionality of related connections may be the same or different than that of the master connection, and neither the original direction 5-tuple nor the conntrack state bits carry this information. If needed, the directionality of the master connection can be stored in master's conntrack mark or labels, which are automatically inherited by the expected related connections. The fact that neither ARP nor ND packets are trackable by conntrack allows mutual exclusion between ARP/ND and the new conntrack original tuple fields. Hence, the IP addresses are overlaid in union with ARP and ND fields. This allows the sw_flow_key to not grow much due to this patch, but it also means that we must be careful to never use the new key fields with ARP or ND packets. ARP is easy to distinguish and keep mutually exclusive based on the ethernet type, but ND being an ICMPv6 protocol requires a bit more attention.

Stateful network admission policy may allow connections to one direction and reject connections initiated in the other direction. After policy change it is possible that for a new connection an overlapping conntrack entry already exists, where the original direction of the existing connection is opposed to the new connection's initial packet. Most importantly, conntrack state relating to the current packet gets the "reply" designation based on whether the original direction tuple or the reply direction tuple matched. If this "directionality" is wrong w.r.t. to the stateful network admission policy it may happen that packets in neither direction are correctly admitted. This patch adds a new "force commit" option to the OVS conntrack action that checks the original direction of an existing conntrack entry. If that direction is opposed to the current packet, the existing conntrack entry is deleted and a new one is subsequently created in the correct direction.

This patchs adds support for scatter-gathering raw memory buffers into a binder transaction, avoiding the need to first serialize them into a Parcel. To remain backwards compatibile with existing binder clients, it introduces two new command ioctls for this purpose - BC_TRANSACTION_SG and BC_REPLY_SG. These commands may only be used with the new binder_transaction_data_sg structure, which adds a field for the total size of the buffers we are scatter-gathering. Because memory buffers may contain pointers to other buffers, we allow callers to specify a parent buffer and an offset into it, to indicate this is a location pointing to the buffer that we are fixing up. The kernel will then take care of fixing up the pointer to that buffer as well.

This change would enable to work with more complex header schemes (vs the simple IPv4 case) where setting a fixed offset relative to the network header is not enough. After this patch, the action has information about the exact header type and field inside this header. This information could be used later on for hardware offloading of pedit. Backward compatibility was being kept: 1. Old kernel <-> new userspace 2. New kernel <-> old userspace 3. add rule using new userspace <-> dump using old userspace 4. add rule using old userspace <-> dump using new userspace When using the extended api, new netlink attributes are being used. This way, operation will fail in (1) and (3) - and no malformed rule be added or dumped. Of course, new user space that doesn't need the new functionality can use the old netlink attributes and operation will succeed. Since action can support both api's, (2) should work, and it is easy to write the new user space to have (4) work. The action is having a strict check that only header types and commands it can handle are accepted. This way future additions will be much easier. Usage example: $ tc filter add dev enp0s9 protocol ip parent ffff: \ flower \ ip_proto tcp \ dst_port 80 \ action pedit munge tcp dport set 8080 pipe \ action mirred egress redirect dev veth0 Will forward tcp port whose original dest port is 80, while modifying the destination port to 8080.

By default it's not passed, therefore override is disallowed. Examples: 1. prog X attached to /A with default prog Y fails to attach to /A/B and /A/B/C Everything under /A runs prog X 2. prog X attached to /A with allow_override. prog Y fails to attach to /A/B with default (non-override) prog M attached to /A/B with allow_override. Everything under /A/B runs prog M only. 3. prog X attached to /A with allow_override. prog Y fails to attach to /A with default. The user has to detach first to switch the mode. In the future this behavior may be extended with a chain of non-overridable programs. Also fix the bug where detach from cgroup where nothing is attached was not throwing error.

The problem is that many drivers can convert R'G'B' content (often from sensors) to Y'CbCr, but they all produce limited range Y'CbCr. To stay backwards compatible the default quantization range for sRGB and AdobeRGB Y'CbCr encoding should be limited range, not full range, even though the corresponding standards specify full range.

All review feedback from the previous submit has been handled and the fixes are included. There's no outstanding issue AFIK. Upstream code just did a s/fe/vmf/ conversion in the page faults and this has been converted as well incrementally. In addition to the previous submits, this also wakes up stuck userfaults during UFFDIO_UNREGISTER. The non cooperative testcase actually reproduced this problem by getting stuck instead of quitting clean in some rare case as it could call UFFDIO_UNREGISTER while some userfault could be still in flight. The other option would have been to keep leaving it up to userland to serialize itself and to patch the testcase instead but the wakeup during unregister I think is preferable. David also asked the UFFD_FEATURE_MISSING_HUGETLBFS and UFFD_FEATURE_MISSING_SHMEM feature flags to be added so QEMU can avoid to probe if the hugetlbfs/shmem missing support is available by calling UFFDIO_REGISTER. QEMU already checks HUGETLBFS_MAGIC with fstatfs so if UFFD_FEATURE_MISSING_HUGETLBFS is also set, it knows UFFDIO_REGISTER will succeed (or if it fails, it's for some other more concerning reason). There's no reason to worry about adding too many feature flags. There are 64 available and worst case we've to bump the API if someday we're really going to run out of them. The round-trip network latency of hugetlbfs userfaults during postcopy live migration is still of the order of dozen milliseconds on 10GBit if at 2MB hugepage granularity so it's working perfectly and it should provide for higher bandwidth or lower CPU usage (which makes it interesting to add an option in the future to support THP granularity too for anonymous memory, UFFDIO_COPY would then have to create THP if alignment/len allows for it). 1GB hugetlbfs granularity will require big changes in hugetlbfs to work so it's deferred for later. This patch (of 42): This adds proper documentation (inline) to avoid the risk of further misunderstandings about the semantics of _IOW/_IOR and it also reminds whoever will bump the UFFDIO_API in the future, to change the two ioctl to _IOW. This was found while implementing strace support for those ioctl, otherwise we could have never found it by just reviewing kernel code and testing it. _IOC_READ or _IOC_WRITE alters nothing but the ioctl number itself, so it's only worth fixing if the UFFDIO_API is bumped someday.

This new descriptor can then be used to get events from the child and populate its mm with data. Note, that there can be different uffd-s controlling different vmas within one mm, so first we should collect all those uffds (and ctx-s) in a list and then notify them all one by one but only once per fork(). The context is created at fork() time but the descriptor, file struct and anon inode object is created at event read time. So some trickery is added to the userfaultfd_ctx_read() to handle the ctx queues' locking vs file creation. Another thing worth noticing is that the task that fork()-s waits for the uffd event to get processed WITHOUT the mmap sem.

These patches add notification of madvise(MADV_REMOVE) event to non-cooperative userfaultfd monitor. The first pacth renames EVENT_MADVDONTNEED to EVENT_REMOVE along with relevant functions and structures. Using _REMOVE instead of _MADVDONTNEED describes the event semantics more clearly and I hope it's not too late for such change in the ABI. This patch (of 3): The UFFD_EVENT_MADVDONTNEED purpose is to notify uffd monitor about removal of certain range from address space tracked by userfaultfd. Hence, UFFD_EVENT_REMOVE seems to better reflect the operation semantics. Respectively, 'madv_dn' field of uffd_msg is renamed to 'remove' and the madvise_userfault_dontneed callback is renamed to userfaultfd_remove.

Addition of UFFD_EVENT_UNMAP allows the uffd monitor to track precisely changes in the virtual memory layout. Since there might be different uffd contexts for the affected VMAs, we first should create a temporary representation for the unmap event for each uffd context and then notify them one by one to the appropriate userfault file descriptors. The event notification occurs after the mmap_sem has been released.

The getattr inode operation is altered to take two additional arguments: a u32 request_mask and an unsigned int flags that indicate the synchronisation mode. This change is propagated to the vfs_getattr*() function. Functions like vfs_stat() are now inline wrappers around new functions vfs_statx() and vfs_statx_fd() to reduce stack usage. ======== OVERVIEW ======== The idea was initially proposed as a set of xattrs that could be retrieved with getxattr(), but the general preference proved to be for a new syscall with an extended stat structure. A number of requests were gathered for features to be included. The following have been included: (1) Make the fields a consistent size on all arches and make them large. (2) Spare space, request flags and information flags are provided for future expansion. (3) Better support for the y2038 problem [Arnd Bergmann] (tv_sec is an __s64). (4) Creation time: The SMB protocol carries the creation time, which could be exported by Samba, which will in turn help CIFS make use of FS-Cache as that can be used for coherency data (stx_btime). This is also specified in NFSv4 as a recommended attribute and could be exported by NFSD [Steve French]. (5) Lightweight stat: Ask for just those details of interest, and allow a netfs (such as NFS) to approximate anything not of interest, possibly without going to the server [Trond Myklebust, Ulrich Drepper, Andreas Dilger] (AT_STATX_DONT_SYNC). (6) Heavyweight stat: Force a netfs to go to the server, even if it thinks its cached attributes are up to date [Trond Myklebust] (AT_STATX_FORCE_SYNC). And the following have been left out for future extension: (7) Data version number: Could be used by userspace NFS servers [Aneesh Kumar]. Can also be used to modify fill_post_wcc() in NFSD which retrieves i_version directly, but has just called vfs_getattr(). It could get it from the kstat struct if it used vfs_xgetattr() instead. (There's disagreement on the exact semantics of a single field, since not all filesystems do this the same way). (8) BSD stat compatibility: Including more fields from the BSD stat such as creation time (st_btime) and inode generation number (st_gen) [Jeremy Allison, Bernd Schubert]. (9) Inode generation number: Useful for FUSE and userspace NFS servers [Bernd Schubert]. (This was asked for but later deemed unnecessary with the open-by-handle capability available and caused disagreement as to whether it's a security hole or not). (10) Extra coherency data may be useful in making backups [Andreas Dilger]. (No particular data were offered, but things like last backup timestamp, the data version number and the DOS archive bit would come into this category). (11) Allow the filesystem to indicate what it can/cannot provide: A filesystem can now say it doesn't support a standard stat feature if that isn't available, so if, for instance, inode numbers or UIDs don't exist or are fabricated locally... (This requires a separate system call - I have an fsinfo() call idea for this). (12) Store a 16-byte volume ID in the superblock that can be returned in struct xstat [Steve French]. (Deferred to fsinfo). (13) Include granularity fields in the time data to indicate the granularity of each of the times (NFSv4 time_delta) [Steve French]. (Deferred to fsinfo). (14) FS_IOC_GETFLAGS value. These could be translated to BSD's st_flags. Note that the Linux IOC flags are a mess and filesystems such as Ext4 define flags that aren't in linux/fs.h, so translation in the kernel may be a necessity (or, possibly, we provide the filesystem type too). (Some attributes are made available in stx_attributes, but the general feeling was that the IOC flags were to ext[234]-specific and shouldn't be exposed through statx this way). (15) Mask of features available on file (eg: ACLs, seclabel) [Brad Boyer, Michael Kerrisk]. (Deferred, probably to fsinfo. Finding out if there's an ACL or seclabal might require extra filesystem operations). (16) Femtosecond-resolution timestamps [Dave Chinner]. (A __reserved field has been left in the statx_timestamp struct for this - if there proves to be a need). (17) A set multiple attributes syscall to go with this. =============== NEW SYSTEM CALL =============== The new system call is: int ret = statx(int dfd, const char *filename, unsigned int flags, unsigned int mask, struct statx *buffer); The dfd, filename and flags parameters indicate the file to query, in a similar way to fstatat(). There is no equivalent of lstat() as that can be emulated with statx() by passing AT_SYMLINK_NOFOLLOW in flags. There is also no equivalent of fstat() as that can be emulated by passing a NULL filename to statx() with the fd of interest in dfd. Whether or not statx() synchronises the attributes with the backing store can be controlled by OR'ing a value into the flags argument (this typically only affects network filesystems): (1) AT_STATX_SYNC_AS_STAT tells statx() to behave as stat() does in this respect. (2) AT_STATX_FORCE_SYNC will require a network filesystem to synchronise its attributes with the server - which might require data writeback to occur to get the timestamps correct. (3) AT_STATX_DONT_SYNC will suppress synchronisation with the server in a network filesystem. The resulting values should be considered approximate. mask is a bitmask indicating the fields in struct statx that are of interest to the caller. The user should set this to STATX_BASIC_STATS to get the basic set returned by stat(). It should be noted that asking for more information may entail extra I/O operations. buffer points to the destination for the data. This must be 256 bytes in size. ====================== MAIN ATTRIBUTES RECORD ====================== The following structures are defined in which to return the main attribute set: struct statx_timestamp { __s64 tv_sec; __s32 tv_nsec; __s32 __reserved; }; struct statx { __u32 stx_mask; __u32 stx_blksize; __u64 stx_attributes; __u32 stx_nlink; __u32 stx_uid; __u32 stx_gid; __u16 stx_mode; __u16 __spare0[1]; __u64 stx_ino; __u64 stx_size; __u64 stx_blocks; __u64 __spare1[1]; struct statx_timestamp stx_atime; struct statx_timestamp stx_btime; struct statx_timestamp stx_ctime; struct statx_timestamp stx_mtime; __u32 stx_rdev_major; __u32 stx_rdev_minor; __u32 stx_dev_major; __u32 stx_dev_minor; __u64 __spare2[14]; }; The defined bits in request_mask and stx_mask are: STATX_TYPE Want/got stx_mode & S_IFMT STATX_MODE Want/got stx_mode & ~S_IFMT STATX_NLINK Want/got stx_nlink STATX_UID Want/got stx_uid STATX_GID Want/got stx_gid STATX_ATIME Want/got stx_atime{,_ns} STATX_MTIME Want/got stx_mtime{,_ns} STATX_CTIME Want/got stx_ctime{,_ns} STATX_INO Want/got stx_ino STATX_SIZE Want/got stx_size STATX_BLOCKS Want/got stx_blocks STATX_BASIC_STATS [The stuff in the normal stat struct] STATX_BTIME Want/got stx_btime{,_ns} STATX_ALL [All currently available stuff] stx_btime is the file creation time, stx_mask is a bitmask indicating the data provided and __spares*[] are where as-yet undefined fields can be placed. Time fields are structures with separate seconds and nanoseconds fields plus a reserved field in case we want to add even finer resolution. Note that times will be negative if before 1970; in such a case, the nanosecond fields will also be negative if not zero. The bits defined in the stx_attributes field convey information about a file, how it is accessed, where it is and what it does. The following attributes map to FS_*_FL flags and are the same numerical value: STATX_ATTR_COMPRESSED File is compressed by the fs STATX_ATTR_IMMUTABLE File is marked immutable STATX_ATTR_APPEND File is append-only STATX_ATTR_NODUMP File is not to be dumped STATX_ATTR_ENCRYPTED File requires key to decrypt in fs Within the kernel, the supported flags are listed by: KSTAT_ATTR_FS_IOC_FLAGS [Are any other IOC flags of sufficient general interest to be exposed through this interface?] New flags include: STATX_ATTR_AUTOMOUNT Object is an automount trigger These are for the use of GUI tools that might want to mark files specially, depending on what they are. Fields in struct statx come in a number of classes: (0) stx_dev_*, stx_blksize. These are local system information and are always available. (1) stx_mode, stx_nlinks, stx_uid, stx_gid, stx_[amc]time, stx_ino, stx_size, stx_blocks. These will be returned whether the caller asks for them or not. The corresponding bits in stx_mask will be set to indicate whether they actually have valid values. If the caller didn't ask for them, then they may be approximated. For example, NFS won't waste any time updating them from the server, unless as a byproduct of updating something requested. If the values don't actually exist for the underlying object (such as UID or GID on a DOS file), then the bit won't be set in the stx_mask, even if the caller asked for the value. In such a case, the returned value will be a fabrication. Note that there are instances where the type might not be valid, for instance Windows reparse points. (2) stx_rdev_*. This will be set only if stx_mode indicates we're looking at a blockdev or a chardev, otherwise will be 0. (3) stx_btime. Similar to (1), except this will be set to 0 if it doesn't exist. ======= TESTING ======= The following test program can be used to test the statx system call: samples/statx/test-statx.c Just compile and run, passing it paths to the files you want to examine. The file is built automatically if CONFIG_SAMPLES is enabled. Here's some example output. Firstly, an NFS directory that crosses to another FSID. Note that the AUTOMOUNT attribute is set because transiting this directory will cause d_automount to be invoked by the VFS.
