2019-02-17devlink: add flash update commandJakub Kicinski1-0/+6
Add devlink flash update command. Advanced NICs have firmware stored in flash and often cryptographically secured. Updating that flash is handled by management firmware. Ethtool has a flash update command which served us well, however, it has two shortcomings: - it takes rtnl_lock unnecessarily - really flash update has nothing to do with networking, so using a networking device as a handle is suboptimal, which leads us to the second one: - it requires a functioning netdev - in case device enters an error state and can't spawn a netdev (e.g. communication with the device fails) there is no netdev to use as a handle for flashing. Devlink already has the ability to report the firmware versions, now with the ability to update the firmware/flash we will be able to recover devices in bad state. To enable updates of sub-components of the FW allow passing component name. This name should correspond to one of the versions reported in devlink info. v1: - replace target id with component name (Jiri).

The netfilter conflicts were rather simple overlapping changes. However, the cls_tcindex.c stuff was a bit more complex. On the 'net' side, Cong is fixing several races and memory leaks. Whilst on the 'net-next' side we have Vlad adding the rtnl-ness support. What I've decided to do, in order to resolve this, is revert the conversion over to using a workqueue that Cong did, bringing us back to pure RCU. I did it this way because I believe that either Cong's races don't apply with have Vlad did things, or Cong will have to implement the race fix slightly differently. Signed-off-by: David S.

2019-02-14time: Add time_types.hDeepa Dinamani2-35/+41
sys/time.h is the mandated include for many time related defines. However, linux/time.h overlaps sys/time.h significantly and this makes including both from userspace or one from the other impossible. This also means that userspace can get away with including sys/time.h whenever it needs linux/time.h and this is what's been happening in the user world usually. But, we have new data types that we plan to use in the uapi time interfaces also defined in the linux/time.h. But, we are unable to use these types when sys/time.h is included. Hence, move the new types to a new header, time_types.h. We intend to eventually have all the uapi defines that the kernel uses defined in this header. Note that the plan is to replace uapi interfaces with timeval to use __kernel_old_timeval, timespec to use __kernel_old_timespec etc. Reported-by: Ran Rozenstein <[email protected]> Fixes: 9718475e6908 ("socket: Add SO_TIMESTAMPING_NEW") Signed-off-by: Deepa Dinamani <[email protected]> Signed-off-by: David S.

2019-02-13bpf: add plumbing for BPF_LWT_ENCAP_IP in bpf_lwt_push_encapPeter Oskolkov1-2/+24
This patch adds all needed plumbing in preparation to allowing bpf programs to do IP encapping via bpf_lwt_push_encap. Actual implementation is added in the next patch in the patchset. Of note: - bpf_lwt_push_encap can now be called from BPF_PROG_TYPE_LWT_XMIT prog types in addition to BPF_PROG_TYPE_LWT_IN; - if the skb being encapped has GSO set, encapsulation is limited to IPIP/IP+GRE/IP+GUE (both IPv4 and IPv6); - as route lookups are different for ingress vs egress, the single external bpf_lwt_push_encap BPF helper is routed internally to either bpf_lwt_in_push_encap or bpf_lwt_xmit_push_encap BPF_CALLs, depending on prog type. v8 changes: fixed a typo.

2019-02-13net: phy: Add generic support for 2.5GBaseT and 5GBaseTMaxime Chevallier1-0/+16
The 802.3bz specification, based on previous by the NBASET alliance, defines the 2.5GBaseT and 5GBaseT link modes for ethernet traffic on cat5e, cat6 and cat7 cables. These mode integrate with the already defined C45 MDIO PMA/PMD registers set that added 10G support, by defining some previously reserved bits, and adding a new register (2.5G/5G Extended abilities). This commit adds the required definitions in include/uapi/linux/mdio.h to support these modes, and detect when a link-partner advertises them. It also adds support for these mode in the generic C45 PHY infrastructure.

2019-02-12inet_diag: fix reporting cgroup classid and fallback to priorityKonstantin Khlebnikov1-5/+11
Field idiag_ext in struct inet_diag_req_v2 used as bitmap of requested extensions has only 8 bits. Thus extensions starting from DCTCPINFO cannot be requested directly. Some of them included into response unconditionally or hook into some of lower 8 bits. Extension INET_DIAG_CLASS_ID has not way to request from the beginning. This patch bundle it with INET_DIAG_TCLASS (ipv6 tos), fixes space reservation, and documents behavior for other extensions. Also this patch adds fallback to reporting socket priority. This filed is more widely used for traffic classification because ipv4 sockets automatically maps TOS to priority and default qdisc pfifo_fast knows about that. But priority could be changed via setsockopt SO_PRIORITY so INET_DIAG_TOS isn't enough for predicting class. Also cgroup2 obsoletes net_cls classid (it always zero), but we cannot reuse this field for reporting cgroup2 id because it is 64-bit (ino+gen). So, after this patch INET_DIAG_CLASS_ID will report socket priority for most common setup when net_cls isn't set and/or cgroup2 in use.

2019-02-10bpf: Add struct bpf_tcp_sock and BPF_FUNC_tcp_sockMartin KaFai Lau1-1/+50
This patch adds a helper function BPF_FUNC_tcp_sock and it is currently available for cg_skb and sched_(cls|act): struct bpf_tcp_sock *bpf_tcp_sock(struct bpf_sock *sk); int cg_skb_foo(struct __sk_buff *skb) { struct bpf_tcp_sock *tp; struct bpf_sock *sk; __u32 snd_cwnd; sk = skb->sk; if (!sk) return 1; tp = bpf_tcp_sock(sk); if (!tp) return 1; snd_cwnd = tp->snd_cwnd; /* ... */ return 1; } A 'struct bpf_tcp_sock' is also added to the uapi bpf.h to provide read-only access. bpf_tcp_sock has all the existing tcp_sock's fields that has already been exposed by the bpf_sock_ops. i.e. no new tcp_sock's fields are exposed in bpf.h. This helper returns a pointer to the tcp_sock. If it is not a tcp_sock or it cannot be traced back to a tcp_sock by sk_to_full_sk(), it returns NULL. Hence, the caller needs to check for NULL before accessing it. The current use case is to expose members from tcp_sock to allow a cg_skb_bpf_prog to provide per cgroup traffic policing/shaping.

2019-02-10bpf: Add state, dst_ip4, dst_ip6 and dst_port to bpf_sockMartin KaFai Lau1-9/+8
This patch adds "state", "dst_ip4", "dst_ip6" and "dst_port" to the bpf_sock. The userspace has already been using "state", e.g. inet_diag (ss -t) and getsockopt(TCP_INFO). This patch also allows narrow load on the following existing fields: "family", "type", "protocol" and "src_port". Unlike IP address, the load offset is resticted to the first byte for them but it can be relaxed later if there is a use case. This patch also folds __sock_filter_check_size() into bpf_sock_is_valid_access() since it is not called by any where else. All bpf_sock checking is in one place.

2019-02-10bpf: Add a bpf_sock pointer to __sk_buff and a bpf_sk_fullsock helperMartin KaFai Lau1-1/+11
In kernel, it is common to check "skb->sk && sk_fullsock(skb->sk)" before accessing the fields in sock. For example, in __netdev_pick_tx: static u16 __netdev_pick_tx(struct net_device *dev, struct sk_buff *skb, struct net_device *sb_dev) { /* ... */ struct sock *sk = skb->sk; if (queue_index != new_index && sk && sk_fullsock(sk) && rcu_access_pointer(sk->sk_dst_cache)) sk_tx_queue_set(sk, new_index); /* ... */ return queue_index; } This patch adds a "struct bpf_sock *sk" pointer to the "struct __sk_buff" where a few of the convert_ctx_access() in filter.c has already been accessing the skb->sk sock_common's fields, e.g. sock_ops_convert_ctx_access(). "__sk_buff->sk" is a PTR_TO_SOCK_COMMON_OR_NULL in the verifier. Some of the fileds in "bpf_sock" will not be directly accessible through the "__sk_buff->sk" pointer. It is limited by the new "bpf_sock_common_is_valid_access()". e.g. The existing "type", "protocol", "mark" and "priority" in bpf_sock are not allowed. The newly added "struct bpf_sock *bpf_sk_fullsock(struct bpf_sock *sk)" can be used to get a sk with all accessible fields in "bpf_sock". This helper is added to both cg_skb and sched_(cls|act). int cg_skb_foo(struct __sk_buff *skb) { struct bpf_sock *sk; sk = skb->sk; if (!sk) return 1; sk = bpf_sk_fullsock(sk); if (!sk) return 1; if (sk->family != AF_INET6 || sk->protocol != IPPROTO_TCP) return 1; /* some_traffic_shaping(); */ return 1; } (1) The sk is read only (2) There is no new "struct bpf_sock_common" introduced. (3) Future kernel sock's members could be added to bpf_sock only instead of repeatedly adding at multiple places like currently in bpf_sock_ops_md, bpf_sock_addr_md, sk_reuseport_md...etc. (4) After "sk = skb->sk", the reg holding sk is in type PTR_TO_SOCK_COMMON_OR_NULL. (5) After bpf_sk_fullsock(), the return type will be in type PTR_TO_SOCKET_OR_NULL which is the same as the return type of bpf_sk_lookup_xxx(). However, bpf_sk_fullsock() does not take refcnt. The acquire_reference_state() is only depending on the return type now. To avoid it, a new is_acquire_function() is checked before calling acquire_reference_state(). (6) The WARN_ON in "release_reference_state()" is no longer an internal verifier bug. When reg->id is not found in state->refs[], it means the bpf_prog does something wrong like "bpf_sk_release(bpf_sk_fullsock(skb->sk))" where reference has never been acquired by calling "bpf_sk_fullsock(skb->sk)". A -EINVAL and a verbose are done instead of WARN_ON. A test is added to the test_verifier in a later patch. Since the WARN_ON in "release_reference_state()" is no longer needed, "__release_reference_state()" is folded into "release_reference_state()" also.

git://git.kernel.org:/pub/scm/linux/kernel/git/arnd/playground into timers/2038 Pull y2038 - time64 system calls from Arnd Bergmann: This series finally gets us to the point of having system calls with 64-bit time_t on all architectures, after a long time of incremental preparation patches. There was actually one conversion that I missed during the summer, i.e. Deepa's timex series, which I now updated based the 5.0-rc1 changes and review comments. The following system calls are now added on all 32-bit architectures using the same system call numbers: 403 clock_gettime64 404 clock_settime64 405 clock_adjtime64 406 clock_getres_time64 407 clock_nanosleep_time64 408 timer_gettime64 409 timer_settime64 410 timerfd_gettime64 411 timerfd_settime64 412 utimensat_time64 413 pselect6_time64 414 ppoll_time64 416 io_pgetevents_time64 417 recvmmsg_time64 418 mq_timedsend_time64 419 mq_timedreceiv_time64 420 semtimedop_time64 421 rt_sigtimedwait_time64 422 futex_time64 423 sched_rr_get_interval_time64 Each one of these corresponds directly to an existing system call that includes a 'struct timespec' argument, or a structure containing a timespec or (in case of clock_adjtime) timeval. Not included here are new versions of getitimer/setitimer and getrusage/waitid, which are planned for the future but only needed to make a consistent API rather than for correct operation beyond y2038. These four system calls are based on 'timeval', and it has not been finally decided what the replacement kernel interface will use instead. So far, I have done a lot of build testing across most architectures, which has found a number of bugs. Runtime testing so far included testing LTP on 32-bit ARM with the existing system calls, to ensure we do not regress for existing binaries, and a test with a 32-bit x86 build of LTP against a modified version of the musl C library that has been adapted to the new system call interface [3]. This library can be used for testing on all architectures supported by musl-1.1.21, but it is not how the support is getting integrated into the official musl release. Official musl support is planned but will require more invasive changes to the library.

2019-02-09batman-adv: Add gateway mesh genl configurationSven Eckelmann1-0/+40
The mesh/soft-interface can optimize the handling of DHCP packets. Instead of flooding them through the whole mesh, it can be forwarded as unicast to a specific gateway server. The originator which injects the packets in the mesh has to select (based on sel_class thresholds) a responsible gateway server. This is done by switching this originator to the gw_mode client. The servers announce their forwarding bandwidth (download/upload) when the gw_mode server was selected. The BATADV_CMD_SET_MESH/BATADV_CMD_GET_MESH commands allow to set/get the configuration of this feature using the attributes: * u8 BATADV_ATTR_GW_MODE (0 == off, 1 == client, 2 == server) * u32 BATADV_ATTR_GW_BANDWIDTH_DOWN (in 100 kbit/s steps) * u32 BATADV_ATTR_GW_BANDWIDTH_UP (in 100 kbit/s steps) * u32 BATADV_ATTR_GW_SEL_CLASS Signed-off-by: Sven Eckelmann <[email protected]> Signed-off-by: Simon Wunderlich <[email protected]>
2019-02-09batman-adv: Add fragmentation mesh genl configurationSven Eckelmann1-0/+7
The mesh interface can fragment unicast packets when the packet size exceeds the outgoing slave/hard-interface MTU. The BATADV_CMD_SET_MESH/BATADV_CMD_GET_MESH commands allow to set/get the configuration of this feature using the BATADV_ATTR_FRAGMENTATION_ENABLED attribute. Setting the u8 to zero will disable this feature and setting it to something else is enabling this feature.

2019-02-09batman-adv: Prepare framework for vlan genl configSven Eckelmann1-0/+17
The batman-adv configuration interface was implemented solely using sysfs. This approach was condemned by non-batadv developers as "huge mistake". Instead a netlink/genl based implementation was suggested. Beside the mesh/soft-interface specific configuration, the VLANs on top of the mesh/soft-interface have configuration settings. The genl interface reflects this by allowing to get/set it using the vlan specific commands BATADV_CMD_GET_VLAN/BATADV_CMD_SET_VLAN. The set command BATADV_CMD_SET_MESH will also notify interested userspace listeners of the "config" mcast group using the BATADV_CMD_SET_VLAN command message type that settings might have been changed and what the current values are.

Bit 0 in register 1.5 doesn't represent a device but is a flag that Clause 22 registers are present. Therefore disregard this bit when populating the device list. If code needs this information it should read register 1.5 directly instead of accessing the device list. Because this bit doesn't represent a device don't define a MDIO_MMD_XYZ constant, just define a MDIO_DEVS_XYZ constant for the flag in the device list bitmap. v2: - make masking of bit 0 more explicit - improve commit message Signed-off-by: Heiner Kallweit <[email protected]> Signed-off-by: David S.

2019-02-07net: phy: let genphy_c45_read_link manage the devices to checkHeiner Kallweit1-0/+2
Let genphy_c45_read_link manage the devices to check, this removes overhead from callers. Add C22EXT to the list of excluded devices because it doesn't implement the status register. According to the 802.3 clause 45 spec registers 29.0 - 29.4 are reserved. At the moment we have very few clause 45 PHY drivers, so we are lacking experience whether other drivers will have to exclude further devices, or may need to check PHY XS. If we should figure out that list of devices to check needs to be configurable, I think best will be to add a device list member to struct phy_driver. v2: - adjusted commit message - exclude also device C22EXT from link checking Signed-off-by: Heiner Kallweit <[email protected]> Reviewed-by: Andrew Lunn <[email protected]> Signed-off-by: David S.
