2018-11-19sctp: define subscribe in sctp_sock as __u16Xin Long1-1/+5
The member subscribe in sctp_sock is used to indicate to which of the events it is subscribed, more like a group of flags. So it's better to be defined as __u16 (2 bytpes), instead of struct sctp_event_subscribe (13 bytes). Note that sctp_event_subscribe is an UAPI struct, used on sockopt calls, and thus it will not be removed. This patch only changes the internal storage of the flags.

2018-11-17net/ncsi: Configure multi-package, multi-channel modes with failoverSamuel Mendoza-Jonas1-0/+15
This patch extends the ncsi-netlink interface with two new commands and three new attributes to configure multiple packages and/or channels at once, and configure specific failover modes. NCSI_CMD_SET_PACKAGE mask and NCSI_CMD_SET_CHANNEL_MASK set a whitelist of packages or channels allowed to be configured with the NCSI_ATTR_PACKAGE_MASK and NCSI_ATTR_CHANNEL_MASK attributes respectively. If one of these whitelists is set only packages or channels matching the whitelist are considered for the channel queue in ncsi_choose_active_channel(). These commands may also use the NCSI_ATTR_MULTI_FLAG to signal that multiple packages or channels may be configured simultaneously. NCSI hardware arbitration (HWA) must be available in order to enable multi-package mode. Multi-channel mode is always available. If the NCSI_ATTR_CHANNEL_ID attribute is present in the NCSI_CMD_SET_CHANNEL_MASK command the it sets the preferred channel as with the NCSI_CMD_SET_INTERFACE command. The combination of preferred channel and channel whitelist defines a primary channel and the allowed failover channels. If the NCSI_ATTR_MULTI_FLAG attribute is also present then the preferred channel is configured for Tx/Rx and the other channels are enabled only for Rx.

2018-11-16net: sched: gred: allow manipulating per-DP RED flagsJakub Kicinski1-0/+1
Allow users to set and dump RED flags (ECN enabled and harddrop) on per-virtual queue basis. Validation of attributes is split from changes to make sure we won't have to undo previous operations when we find out configuration is invalid. The objective is to allow changing per-Qdisc parameters without overwriting the per-vq configured flags. Old user space will not pass the TCA_GRED_VQ_FLAGS attribute and per-Qdisc flags will always get propagated to the virtual queues. New user space which wants to make use of per-vq flags should set per-Qdisc flags to 0 and then configure per-vq flags as it sees fit. Once per-vq flags are set per-Qdisc flags can't be changed to non-zero. Vice versa - if the per-Qdisc flags are non-zero the TCA_GRED_VQ_FLAGS attribute has to either be omitted or set to the same value as per-Qdisc flags. Update per-Qdisc parameters: per-Qdisc | per-VQ | result 0 | 0 | all vq flags updated 0 | non-0 | error (vq flags in use) non-0 | 0 | -- impossible -- non-0 | non-0 | all vq flags updated Update per-VQ state (flags parameter not specified): no change to flags Update per-VQ state (flags parameter set): per-Qdisc | per-VQ | result 0 | any | per-vq flags updated non-0 | 0 | -- impossible -- non-0 | non-0 | error (per-Qdisc flags in use) Signed-off-by: Jakub Kicinski <[email protected]> Reviewed-by: John Hurley <[email protected]> Signed-off-by: David S.

Similar to 80ba92fa1a92 ("codel: add ce_threshold attribute") After EDT adoption, it became easier to implement DCTCP-like CE marking. In many cases, queues are not building in the network fabric but on the hosts themselves. If packets leaving fq missed their Earliest Departure Time by XXX usec, we mark them with ECN CE.

2018-11-09ptp: add PTP_SYS_OFFSET_EXTENDED ioctlMiroslav Lichvar1-0/+12
The PTP_SYS_OFFSET ioctl, which can be used to measure the offset between a PHC and the system clock, includes the total time that the driver needs to read the PHC timestamp. This typically involves reading of multiple PCI registers (sometimes in multiple iterations) and the register that contains the lowest bits of the timestamp is not read in the middle between the two readings of the system clock. This asymmetry causes the measured offset to have a significant error. Introduce a new ioctl, driver function, and helper functions, which allow the reading of the lowest register to be isolated from the other readings in order to reduce the asymmetry. The ioctl returns three timestamps for each measurement: - system time right before reading the lowest bits of the PHC timestamp - PHC time - system time immediately after reading the lowest bits of the PHC timestamp Cc: Richard Cochran <[email protected]> Cc: Jacob Keller <[email protected]> Cc: Marcelo Tosatti <[email protected]> Signed-off-by: Miroslav Lichvar <[email protected]> Signed-off-by: David S.

Add a new "peer measurement" API, that can be used to measure certain things related to a peer. Right now, only implement FTM (flight time measurement) over it, but the idea is that it'll be extensible to also support measuring the necessary things to calculate e.g. angle-of-arrival for WiGig. The API is structured to have a generic list of peers and channels to measure with/on, and then for each of those a set of measurements (again, only FTM right now) to perform. Results are sent to the requesting socket, including a final complete message. Closing the controlling netlink socket will abort a running measurement. v3: - add a bit to report "final" for partial results - remove list keeping etc. and just unicast out the results to the requester (big code reduction ...) - also send complete message unicast, and as a result remove the multicast group - separate out struct cfg80211_pmsr_ftm_request_peer from struct cfg80211_pmsr_request_peer - document timeout == 0 if no timeout - disallow setting timeout nl80211 attribute to 0, must not include attribute for no timeout - make MAC address randomization optional - change num bursts exponent default to 0 (1 burst, rather rather than the old default of 15==don't care) v4: - clarify NL80211_ATTR_TIMEOUT documentation v5: - remove unnecessary nl80211 multicast/family changes - remove partial results bit/flag, final is sufficient - add max_bursts_exponent, max_ftms_per_burst to capability - rename "frames per burst" -> "FTMs per burst" v6: - rename cfg80211_pmsr_free_wdev() to cfg80211_pmsr_wdev_down() and call it in leave, so the device can't go down with any pending measurements v7: - wording fixes (Lior) - fix ftm.max_bursts_exponent to allow having the limit of 0 (Lior) v8: - copyright statements - minor coding style fixes - fix error path leak Signed-off-by: Johannes Berg <[email protected]>

Now that ICMP error handling is working for GENEVE, we can comply with this recommendation. Make this configurable, though, to avoid breaking existing setups. By default, DF won't be set. It can be set or inherited from inner IPv4 packets. If it's configured to be inherited and we are encapsulating IPv6, it will be set. This only applies to non-lwt tunnels: if an external control plane is used, tunnel key will still control the DF flag. v2: - DF behaviour configuration only applies for non-lwt tunnels, apply DF setting only if (!geneve->collect_md) in geneve_xmit_skb() (Stephen Hemminger) Signed-off-by: Stefano Brivio <[email protected]> Reviewed-by: Sabrina Dubroca <[email protected]> Signed-off-by: David S.

2018-11-08vxlan: Allow configuration of DF behaviourStefano Brivio1-0/+9
Allow users to set the IPv4 DF bit in outgoing packets, or to inherit its value from the IPv4 inner header. If the encapsulated protocol is IPv6 and DF is configured to be inherited, always set it. For IPv4, inheriting DF from the inner header was probably intended from the very beginning judging by the comment to vxlan_xmit(), but it wasn't actually implemented -- also because it would have done more harm than good, without handling for ICMP Fragmentation Needed messages. According to RFC 7348, "Path MTU discovery MAY be used". An expired RFC draft, draft-saum-nvo3-pmtud-over-vxlan-05, whose purpose was to describe PMTUD implementation, says that "is a MUST that Vxlan gateways [...] SHOULD set the DF-bit [...]", whatever that means. Given this background, the only sane option is probably to let the user decide, and keep the current behaviour as default. This only applies to non-lwt tunnels: if an external control plane is used, tunnel key will still control the DF flag. v2: - DF behaviour configuration only applies for non-lwt tunnels, move DF setting to if (!info) block in vxlan_xmit_one() (Stephen Hemminger) Signed-off-by: Stefano Brivio <[email protected]> Reviewed-by: Sabrina Dubroca <[email protected]> Signed-off-by: David S.

This is the RX counterpart of commit bec1f6f69736 ("udp: generate gso with UDP_SEGMENT").

Initial benchmark numbers: Before: udp rx: 1079 MB/s 769065 calls/s After: udp rx: 1466 MB/s 24877 calls/s This change introduces a side effect in respect to UDP tunnels: after a UDP tunnel creation, now the kernel performs a lookup per ingress UDP packet, while before such lookup happened only if the ingress packet carried a valid internal header csum. rfc v2 -> rfc v3: - fixed typos in macro name and comments - really enforce UDP_GRO_CNT_MAX, instead of UDP_GRO_CNT_MAX + 1 - acquire socket lock in UDP_GRO setsockopt rfc v1 -> rfc v2: - use a new option to enable UDP GRO - use static keys to protect the UDP GRO socket lookup Signed-off-by: Paolo Abeni <[email protected]> Signed-off-by: David S.

2018-11-06media: v4l: fix uapi mpeg slice params definitionArnd Bergmann1-2/+5
We get a headers_check warning about the newly defined ioctl command structures: ./usr/include/linux/v4l2-controls.h:1105: found __[us]{8,16,32,64} type without #include <linux/types.h> This is resolved by including linux/types.h, as suggested by the warning, but there is another problem: Three of the four structures have an odd number of __u8 headers, but are aligned to 32 bit in the v4l2_ctrl_mpeg2_slice_params, so we get an implicit padding byte for each one. To solve that, let's add explicit padding that can be set to zero and verified in the kernel.

2018-11-05drm/amdgpu: Add DCC flags for GFX9 amdgpu_boNicholas Kazlauskas1-0/+6
[Why] Hardware support for Delta Color Compression (DCC) decompression is available in DC for GFX9 but there's no way for userspace to enable the feature. Enabling the feature can provide improved GFX performance and power savings in many situations. [How] Extend the GFX9 tiling flags to include DCC parameters. These are logically grouped together with tiling flags even if they are technically distinct. This trivially maintains backwards compatibility with existing users of amdgpu_gem_metadata. No new IOCTls or data structures are needed to support DCC. This patch helps expose DCC attributes to both libdrm and amdgpu_dm.
