2022-08-02wireguard: allowedips: don't corrupt stack when detecting overflowJason A. Donenfeld2-6/+9
In case push_rcu() and related functions are buggy, there's a WARN_ON(len >= 128), which the selftest tries to hit by being tricky. In case it is hit, we shouldn't corrupt the kernel's stack, though; otherwise it may be hard to even receive the report that it's buggy. So conditionalize the stack write based on that WARN_ON()'s return value. Note that this never *actually* happens anyway. The WARN_ON() in the first place is bounded by IS_ENABLED(DEBUG), and isn't expected to ever actually hit. This is just a debugging sanity check. Additionally, hoist the constant 128 into a named enum, MAX_ALLOWEDIPS_BITS, so that it's clear why this value is chosen.

2022-08-02wireguard: ratelimiter: use hrtimer in selftestJason A. Donenfeld1-11/+14
Using msleep() is problematic because it's compared against ratelimiter.c's ktime_get_coarse_boottime_ns(), which means on systems with slow jiffies (such as UML's forced HZ=100), the result is inaccurate. So switch to using schedule_hrtimeout(). However, hrtimer gives us access only to the traditional posix timers, and none of the _COARSE variants. So now, rather than being too imprecise like jiffies, it's too precise. One solution would be to give it a large "range" value, but this will still fire early on a loaded system. A better solution is to align the timeout to the actual coarse timer, and then round up to the nearest tick, plus change. So add the timeout to the current coarse time, and then schedule_hrtimer() until the absolute computed time. This should hopefully reduce flakes in CI as well. Note that we keep the retry loop in case the entire function is running behind, because the test could still be scheduled out, by either the kernel or by the hypervisor's kernel, in which case restarting the test and hoping to not be scheduled out still helps.

Striding RQ uses MTT page mapping, where each page corresponds to an XSK frame. MTT pages have alignment requirements, and XSK frames don't have any alignment guarantees in the unaligned mode.

2022-08-02net: usb: ax88179_178a: Bind only to vendor-specific interfaceHector Martin1-13/+13
The Anker PowerExpand USB-C to Gigabit Ethernet adapter uses this chipset, but exposes CDC Ethernet configurations as well as the vendor specific one. This driver tries to bind by PID:VID unconditionally and ends up picking up the CDC configuration, which is supposed to be handled by the class driver. To make things even more confusing, it sees both of the CDC class interfaces and tries to bind twice, resulting in two broken Ethernet devices. Change all the ID matches to specifically match the vendor-specific interface. By default the device comes up in CDC mode and is bound by that driver (which works fine); users may switch it to the vendor interface using sysfs to set bConfigurationValue, at which point the device actually goes through a reconnect cycle and comes back as a vendor specific only device, and then this driver binds and works too. The affected device uses VID/PID 0b95:1790, but we might as well change all of them for good measure, since there is no good reason for this driver to bind to standard CDC Ethernet interfaces. v3: Added VID/PID info to commit message Signed-off-by: Hector Martin <marcan@marcan.st> Link: https://lore.kernel.org/r/20220731072209.45504-1-marcan@marcan.st Signed-off-by: Paolo Abeni <pabeni@redhat.com>

This refixes: commit 7da17624e7948d5d9660b910f8079d26d26ce453 nt: usb: USB_RTL8153_ECM should not default to y In general, device drivers should not be enabled by default. which basically broke the commit it claimed to fix, ie: commit 657bc1d10bfc23ac06d5d687ce45826c760744f9 r8153_ecm: avoid to be prior to r8152 driver Avoid r8153_ecm is compiled as built-in, if r8152 driver is compiled as modules. Otherwise, the r8153_ecm would be used, even though the device is supported by r8152 driver. this commit amounted to: drivers/net/usb/Kconfig: +config USB_RTL8153_ECM + tristate "RTL8153 ECM support" + depends on USB_NET_CDCETHER && (USB_RTL8152 || USB_RTL8152=n) + default y + help + This option supports ECM mode for RTL8153 ethernet adapter, when + CONFIG_USB_RTL8152 is not set, or the RTL8153 device is not + supported by r8152 driver. drivers/net/usb/Makefile: -obj-$(CONFIG_USB_NET_CDCETHER) += cdc_ether.o r8153_ecm.o +obj-$(CONFIG_USB_NET_CDCETHER) += cdc_ether.o +obj-$(CONFIG_USB_RTL8153_ECM) += r8153_ecm.o And as can be seen it pulls a piece of the cdc_ether driver out into a separate config option to be able to make this piece modular in case cdc_ether is builtin, while r8152 is modular. While in general, device drivers should indeed not be enabled by default: this isn't a device driver per say, but rather this is support code for the CDCETHER (ECM) driver, and should thus be enabled if it is enabled.

I believe this way we don't bring back Marek's complaint. Side note: these incorrect defaults will result in Android 13 on 5.15 GKI kernels lacking USB_RTL8153_ECM support while having USB_NET_CDCETHER (luckily we also have USB_RTL8150 and USB_RTL8152, so it's probably only an issue for very new RTL815x hardware with no native 5.15 driver).

PTP messages like SYNC, FOLLOW_UP, DELAY_REQ are of size 58 bytes. Using a minimum packet length as 64 makes NIX to pad 6 bytes of zeroes while transmission. This is causing latest ptp4l application to emit errors since length in PTP header and received packet are not same. Padding upto 3 bytes is fine but more than that makes ptp4l to assume the pad bytes as a TLV. Hence reduce the size to 60 from 64.

But it is a normal case for tc flower since user can setup a tunnel with tunnel ID is 0. So we need to support this case to accept tunnel key action without tunnel key ID.

This improves the precision of the frequency adjustments by taking advantage of the full scaled parts per million input coming from user space. In addition, all implementations are converted to using the mul_u64_u64_div_u64 function which better handles the intermediate value. This function supports architecture specific instructions where possible to avoid loss of precision if the normal 64-bit multiplication would overflow. Of note, the i40e implementation is now able to avoid loss of precision on slower link speeds by taking advantage of this to multiply by the link speed factor first. This results in a significantly more precise adjustment by allowing the calculation to impact the lower bits. This also gets us a step closer to being able to remove the .adjfreq entirely by removing its use from many drivers. I plan to follow this up with a series to update the drivers from other vendors and drop the .adjfreq implementation entirely. * '1GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue: igb: convert .adjfreq to .adjfine ixgbe: convert .adjfreq to .adjfine i40e: convert .adjfreq to .adjfine i40e: use mul_u64_u64_div_u64 for PTP frequency calculation e1000e: convert .adjfreq to .adjfine e1000e: remove unnecessary range check in e1000e_phc_adjfreq ice: implement adjfine with mul_u64_u64_div_u64 ==================== Link: https://lore.kernel.org/r/20220728181836.3387862-1-anthony.l.nguyen@intel.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>

2022-07-30sfc: use a dynamic m-port for representor RX and set it promiscEdward Cree7-3/+158
Representors do not want to be subject to the PF's Ethernet address filters, since traffic from VFs will typically have a destination either elsewhere on the link segment or on an overlay network. So, create a dynamic m-port with promiscuous and all-multicast filters, and set it as the egress port of representor default rules. Since the m-port is an alias of the calling PF's own m-port, traffic will still be delivered to the PF's RXQs, but it will be subject to the VNRX filter rules installed on the dynamic m-port (specified by the v-port ID field of the filter spec).

2022-07-30sfc: insert default MAE rules to connect VFs to representorsEdward Cree13-6/+606
Default rules are low-priority switching rules which the hardware uses in the absence of higher-priority rules. Each representor requires a corresponding rule matching traffic from its representee VF and delivering to the PF (where a check on INGRESS_MPORT in __ef100_rx_packet() will direct it to the representor). No rule is required in the reverse direction, because representor TX uses a TX override descriptor to bypass the MAE and deliver directly to the VF. Since inserting any rule into the MAE disables the firmware's own default rules, also insert a pair of rules to connect the PF to the physical network port and vice-versa.

2022-07-30sfc: ef100 representor RX top halfEdward Cree2-0/+56
Representor RX uses a NAPI context driven by a 'fake interrupt': when the parent PF receives a packet destined for the representor, it adds it to an SKB list (efv->rx_list), and schedules NAPI if the 'fake interrupt' is primed. The NAPI poll then pulls packets off this list and feeds them to the stack with netif_receive_skb_list(). This scheme allows us to decouple representor RX from the parent PF's RX fast-path. This patch implements the 'top half', which builds an SKB, copies data into it from the RX buffer (which can then be released), adds it to the queue and fires the 'fake interrupt' if necessary.

Without this patch, iavf could send settings for max_rate limiting that would be accepted from by PF even the max_rate option is less than expected 50Mbps quanta. It results in no rate limiting on traffic as rate limiting will be floored to 0. Example: tc qdisc add dev $vf root mqprio num_tc 3 map 0 2 1 queues \ 2@0 2@2 2@4 hw 1 mode channel shaper bw_rlimit \ max_rate 50Mbps 500Mbps 500Mbps Should limit TC0 to circa 50 Mbps tc qdisc add dev $vf root mqprio num_tc 3 map 0 2 1 queues \ 2@0 2@2 2@4 hw 1 mode channel shaper bw_rlimit \ max_rate 0Mbps 100Kbit 500Mbps Should return error Fixes: d5b33d024496 ("i40evf: add ndo_setup_tc callback to i40evf") Signed-off-by: Przemyslaw Patynowski <przemyslawx.patynowski@intel.com> Signed-off-by: Jun Zhang <xuejun.zhang@intel.com> Tested-by: Bharathi Sreenivas <bharathi.sreenivas@intel.com> Signed-off-by: Tony Nguyen <anthony.l.nguyen@intel.com>

2022-07-29wifi: rtw88: check the return value of alloc_workqueue()William Dean1-0/+4
The function alloc_workqueue() in rtw_core_init() can fail, but there is no check of its return value. To fix this bug, its return value should be checked with new error handling code.

2022-07-29wifi: rtw89: 8852a: adjust IMR for SER L1Zong-Zhe Yang1-1/+1
SER (system error recovery) L1 (level 1) has a step-by-step handshake process with FW. These handshakes still rely on B_AX_HS0ISR_IND_INT_EN. So, even already during recovery, we enable this bit in IMR.
