2018-01-19net: sched: cls: add extack support for tcf_exts_validateAlexander Aring13-32/+50
The tcf_exts_validate function calls the act api change callback. For preparing extack support for act api, this patch adds the extack as parameter for this function which is common used in cls implementations. Furthermore the tcf_exts_validate will call action init callback which prepares the TC action subsystem for extack support.

2018-01-19mlxsw: spectrum: Upper-bound supported FW versionYuval Mintz1-19/+11
During initialization the driver checks whether the flashed FW image suits its requirements by checking that it's sufficiently new. However, there's only a weak backward compatibility scheme that is actually guaranteed by the FW, so driver must also upper bound the version to prevent compatibility issues between current driver and some possible future fw.

2018-01-19Merge branch 'nfp-devlink-capabilities-extensions-and-updates'David S. Miller19-208/+463
Jakub Kicinski says: ==================== nfp: devlink, capabilities extensions and updates This series starts with an improvement to the usability of the device memory accessors (CPP transactions). Next few patches are devoted to fixing the devlink locking. After recent patches for mlxsw the locking scheme of devlink ops has to be reworked. Following patches improve NFP code dealing with "representors", and expands the error message printed when driver has no support for loaded FW. Second part of the series is focused on vNIC capabilities read from vNIC control memory (often referred to as "BAR0" for historical reasons). TLV capability format is established and immediately made use of. The next patches rework parsing of features for control vNIC which allows apps to mask out features they don't want enabled. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

BPF firmware currently exposes IRQ moderation capability. The driver will make use of it by default, inserting 50 usec delay to every control message exchange. This cuts the number of messages per second we can exchange by almost half. None of the other capabilities make much sense for BPF control vNIC, either. Disable them all.

2018-01-19nfp: add TLV capabilities to the BARJakub Kicinski5-3/+186
NFP is entirely programmable, including the PCI data interface. Using a fixed control BAR layout certainly makes implementations easier, but require careful considerations when space is allocated. Once BAR area is allocated to one feature nothing else can use it. Allocating space statically also requires it to be sized upfront, which leads to either unnecessary limitation or wastage. We currently have a 32bit capability word defined which tells drivers which application FW features are supported. Most of the bits are exhausted. The same bits are also reused for enabling specific features. Bulk of capabilities don't have a need for an enable bit, however, leading to confusion and wastage. TLVs seems like a better fit for expressing capabilities of applications running on programmable hardware. This patch leaves the front of the BAR as is, and declares a TLV capability start at offset 0x58. Most of the space up to 0x0d90 is already allocated, but the used space can be wrapped with RESERVED TLVs. E.g.: Address Type Length 0x0058 RESERVED 0xe00 /* Wrap basic structures */ 0x0e5c FEATURE_A 0x004 0x0e64 FEATURE_B 0x004 0x0e6c RESERVED 0x990 /* Wrap qeueue stats */ 0x1800 FEATURE_C 0x100 Signed-off-by: Jakub Kicinski <jakub.kicinski@netronome.com> Reviewed-by: Dirk van der Merwe <dirk.vandermerwe@netronome.com> Signed-off-by: David S.

2018-01-19nfp: register devlink after app is createdJakub Kicinski3-36/+29
Devlink used to have two global locks: devlink lock and port lock, our lock ordering looked like this: devlink lock -> driver's pf->lock -> devlink port lock After recent changes port lock was replaced with per-instance lock. Unfortunately, new per-instance lock is taken on most operations now. This means we can only grab the pf->lock from the port split/unsplit ops. Lock ordering looks like this: devlink lock -> driver's pf->lock -> devlink instance lock Since we can't take pf->lock from most devlink ops, make sure nfp_apps are prepared to service them as soon as devlink is registered. Locking the pf must be pushed down after nfp_app_init() callback. The init order looks like this: nfp_app_init devlink_register nfp_app_start netdev/port_register As soon as app_init is done nfp_apps must be ready to service devlink-related callbacks. apps can only register their own devlink objects from nfp_app_start.

Yuchung Cheng says: ==================== tcp: do not use RTT from delayed ACKs for min-RTT This patch set prevents TCP sender from using RTT samples from (suspected) delayed ACKs as the minimum RTT, to avoid unbounded over-estimation of the network path delay.

2018-01-19tcp: avoid min RTT bloat by skipping RTT from delayed-ACK in BBRYuchung Cheng3-1/+4
A persistent connection may send tiny amount of data (e.g. health-check) for a long period of time. BBR's windowed min RTT filter may only see RTT samples from delayed ACKs causing BBR to grossly over-estimate the path delay depending how much the ACK was delayed at the receiver. This patch skips RTT samples that are likely coming from delayed ACKs. Note that it is possible the sender never obtains a valid measure to set the min RTT. In this case BBR will continue to set cwnd to initial window which seems fine because the connection is thin stream.

ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/mkl/linux-can-next Marc Kleine-Budde says: ==================== pull-request: can-next 2018-01-16 this is a pull request for net-next/master consisting of 9 patches. This is a series of patches, some of them initially by Franklin S Cooper Jr, which was picked up by Faiz Abbas. Faiz Abbas added some patches while working on this series, I contributed one as well. The first two patches add support to CAN device infrastructure to limit the bitrate of a CAN adapter if the used CAN-transceiver has a certain maximum bitrate. The remaining patches improve the m_can driver. They add support for bitrate limiting to the driver, clean up the driver and add support for runtime PM. ==================== Signed-off-by: David S.
