2020-09-28mac80211: avoid rate init for S1G bandThomas Pedersen

S1G doesn't have legacy (sband->bitrates) rates, only MCS. For now, just send a frame at MCS 0 if a low rate is requested. Note we also redefine (since we're out of TX flags) TX_RC_VHT_MCS as TX_RC_S1G_MCS to indicate an S1G MCS. This is probably OK as VHT MCS is not valid on S1G band and vice versa.

2020-09-28Merge 'xfrm: Add compat layer'Steffen Klassert
Dmitry Safonov says: ==================== Changes since v2: - added struct xfrm_translator as API to register xfrm_compat.ko with xfrm_state.ko. This allows compilation of translator as a loadable module - fixed indention and collected reviewed-by (Johannes Berg) - moved boilerplate from commit messages into cover-letter (Steffen Klassert) - found on KASAN build and fixed non-initialised stack variable usage in the translator The resulting v2/v3 diff can be found here: https://gist.github.com/0x7f454c46/8f68311dfa1f240959fdbe7c77ed2259 Patches as a .git branch: https://github.com/0x7f454c46/linux/tree/xfrm-compat-v3 Changes since v1: - reworked patches set to use translator - separated the compat layer into xfrm_compat.c, compiled under XFRM_USER_COMPAT config - 32-bit messages now being sent in frag_list (like wext-core does) - instead of __packed add compat_u64 members in compat structures - selftest reworked to kselftest lib API - added netlink dump testing to the selftest XFRM is disabled for compatible users because of the UABI difference. The difference is in structures paddings and in the result the size of netlink messages differ. Possibility for compatible application to manage xfrm tunnels was disabled by: the commmit 19d7df69fdb2 ("xfrm: Refuse to insert 32 bit userspace socket policies on 64 bit systems") and the commit 74005991b78a ("xfrm: Do not parse 32bits compiled xfrm netlink msg on 64bits host"). This is my second attempt to resolve the xfrm/compat problem by adding the 64=>32 and 32=>64 bit translators those non-visibly to a user provide translation between compatible user and kernel. Previous attempt was to interrupt the message ABI according to a syscall by xfrm_user, which resulted in over-complicated code [1]. Florian Westphal provided the idea of translator and some draft patches in the discussion. In these patches, his idea is reused and some of his initial code is also present. There were a couple of attempts to solve xfrm compat problem: https://lkml.org/lkml/2017/1/20/733 https://patchwork.ozlabs.org/patch/44600/ http://netdev.vger.kernel.narkive.com/2Gesykj6/patch-net-next-xfrm-correctly-parse-netlink-msg-from-32bits-ip-command-on-64bits-host All the discussions end in the conclusion that xfrm should have a full compatible layer to correctly work with 32-bit applications on 64-bit kernels: https://lkml.org/lkml/2017/1/23/413 https://patchwork.ozlabs.org/patch/433279/ In some recent lkml discussion, Linus said that it's worth to fix this problem and not giving people an excuse to stay on 32-bit kernel: https://lkml.org/lkml/2018/2/13/752 There is also an selftest for ipsec tunnels. It doesn't depend on any library and compat version can be easy build with: make CFLAGS=-m32 net/ipsec [1]: https://lkml.kernel.org/r/20180726023144.31066-1-dima@arista.com ==================== Signed-off-by: Steffen Klassert <steffen.klassert@secunet.com>

The new phy_state field replaces the unused loop_back field. Log a message when the phy_state changes state.

It will be necessary to update more than one field in the link_info structure when PAM4 speeds are added in a later patch. Instead of merely translating ethtool speed values to firmware speed values, change the responsiblity of this function to update all the necessary link_info fields required to force the speed change to the desired ethtool value. This also reduces code duplication somewhat at the two call sites, which otherwise both have to independently update link_info fields to turn off auto negotiation advertisements. Also use the appropriate REQ_FORCE_LINK_SPEED definitions. These happen to have the same values, but req_link_speed is utilimately passed as force_link_speed in HWRM_PORT_PHY_CFG which is not defined in terms of REQ_AUTO_LINK_SPEED.

2020-09-27bnxt_en: refactor code to limit speed advertisingEdwin Peer
Extract the code for determining an advertised speed is no longer supported into a separate function. This will avoid some code duplication in a later patch when supporting PAM4 speeds, since these speeds are specified in a separate field.

2020-09-27bnxt_en: Update firmware interface spec to 1.10.1.65.Michael Chan
The main changes include FEC, ECN statistics, HWRM_PORT_PHY_QCFG response size reduction, and a new counter added to ctx_hw_stats_ext struct to support the new 58818 chip. The ctx_hw_stats_ext structure is now the superset supporting the new 58818 chips and the prior P5 chips. Add a new flag to identify the new chip and use constants for the chip specific ring statistics sizes instead of the size of the structure. Because the HWRM_PORT_PHY_QCFG response structure size has shrunk back to 96 bytes, the workaround added earlier to limit the size of this message for forwarding to the VF can be removed.

2020-09-27Merge branch 'mlxsw-Expose-transceiver-overheat-counter'David S. Miller
Ido Schimmel says: ==================== mlxsw: Expose transceiver overheat counter Amit says: An overheated transceiver can be the root cause of various network problems such as link flapping. Counting the number of times a transceiver's temperature was higher than its configured threshold can therefore help in debugging such issues. This patch set exposes a transceiver overheat counter via ethtool. This is achieved by configuring the Spectrum ASIC to generate events whenever a transceiver is overheated. The temperature thresholds are queried from the transceiver (if available) and set to the default otherwise. Example: ... transceiver_overheat: 2 Patch set overview: Patches #1-#3 add required device registers Patches #4-#5 add required infrastructure in mlxsw to configure and count overheat events Patches #6-#9 gradually add support for the transceiver overheat counter Patch #10 exposes the transceiver overheat counter via ethtool ==================== Signed-off-by: David S.

2020-09-27mlxsw: Update module's settings when module is plugged inAmit Cohen
Module temperature warning events are enabled for modules that have a temperature sensor and configured according to the temperature thresholds queried from the module. When a module is unplugged we are guaranteed not to get temperature warning events. However, when a module is plugged in we need to potentially update its current settings (i.e., event enablement and thresholds). Register to port module plug/unplug events and update module's settings upon plug in events.

2020-09-27mlxsw: spectrum: Initialize netdev's module overheat counterAmit Cohen
The overheat counter is a per-module counter, but it is exposed as part of the corresponding netdev's statistics. It should therefore be presented to user space relative to the netdev's lifetime. Query the counter just before registering the netdev, so that the value exposed to user space will be relative to this initial value.
