Time Averaged SAR (TAS) tracks the amount of transmit power over a period of time and adjusts the power accordingly. Two thresholds are used to determine when to increase or reduce transmit power: Dynamic Power Reduction (DPR) on/off. Compared to Static SAR, which has a constant transmit power, TAS can improve the user experience or range extension. TAS can be enabled through BIOS, and the driver will evaluate Realtek ACPI DSM with RTW89_ACPI_DSM_FUNC_TAS_EN to determine whether TAS should be enabled. Signed-off-by:

The current implementation seems to reinvent what `kstrtoul` already does in terms of functionality and error handling. Remove uses of `simple_strtoul()` in favor of `kstrtoul()`. There is the following note at `lib/vsprintf.c:simple_strtoull()` which further backs this change: | * This function has caveats. Please use kstrtoull (or kstrtoul) instead. And here, simple_str* are explicitly deprecated [3]. This patch also removes an instance of the deprecated `strncpy` which helps [2]. Compile tested only.

Fix this issue and add related tests as Ido and David suggested. ==================== Signed-off-by: -
Hangbin Liu authored
Add a test case for IPv6 source address delete. As David suggested, add tests: - Single device using src address - Two devices with the same source address - VRF with single device using src address - VRF with two devices using src address As Ido points out, in IPv6, the preferred source address is looked up in the same VRF as the first nexthop device. This will give us similar results to IPv4 if the route is installed in the same VRF as the nexthop device, but not when the nexthop device is enslaved to a different VRF. So add tests: - src address and nexthop dev in same VR - src address and nexthop device in different VRF The link local address delete logic is different from the global address. It should only affect the associate device it bonds to. So add tests cases for link local address testing. Here is the test result: IPv6 delete address route tests Single device using src address TEST: Prefsrc removed when src address removed on other device [ OK ] Two devices with the same source address TEST: Prefsrc not removed when src address exist on other device [ OK ] TEST: Prefsrc removed when src address removed on all devices [ OK ] VRF with single device using src address TEST: Prefsrc removed when src address removed on other device [ OK ] VRF with two devices using src address TEST: Prefsrc not removed when src address exist on other device [ OK ] TEST: Prefsrc removed when src address removed on all devices [ OK ] src address and nexthop dev in same VRF TEST: Prefsrc removed from VRF when source address deleted [ OK ] TEST: Prefsrc in default VRF not removed [ OK ] TEST: Prefsrc not removed from VRF when source address exist [ OK ] TEST: Prefsrc in default VRF removed [ OK ] src address and nexthop device in different VRF TEST: Prefsrc not removed from VRF when nexthop dev in diff VRF [ OK ] TEST: Prefsrc not removed in default VRF [ OK ] TEST: Prefsrc removed from VRF when nexthop dev in diff VRF [ OK ] TEST: Prefsrc removed in default VRF [ OK ] Table ID 0 TEST: Prefsrc removed from default VRF when source address deleted [ OK ] Link local source route TEST: Prefsrc not removed when delete ll addr from other dev [ OK ] TEST: Prefsrc removed when delete ll addr [ OK ] TEST: Prefsrc not removed when delete ll addr from other dev [ OK ] TEST: Prefsrc removed even ll addr still exist on other dev [ OK ] Tests passed: 19 Tests failed: 0 Suggested-by: -

After deleting an IPv6 address on an interface and cleaning up the related preferred source entries, it is important to ensure that all routes associated with the deleted address are properly cleared. The current implementation of rt6_remove_prefsrc() only checks the preferred source addresses bound to the current device. However, there may be routes that are bound to other devices but still utilize the same preferred source address. To address this issue, it is necessary to also delete entries that are bound to other interfaces but share the same source address with the current device. Failure to delete these entries would leave routes that are bound to the deleted address unclear. Here is an example reproducer (I have omitted unrelated routes): + ip link add dummy1 type dummy + ip link add dummy2 type dummy + ip link set dummy1 up + ip link set dummy2 up + ip addr add 1:2:3:4::5/64 dev dummy1 + ip route add 7:7:7:0::1 dev dummy1 src 1:2:3:4::5 + ip route add 7:7:7:0::2 dev dummy2 src 1:2:3:4::5 + ip -6 route show 1:2:3:4::/64 dev dummy1 proto kernel metric 256 pref medium 7:7:7::1 dev dummy1 src 1:2:3:4::5 metric 1024 pref medium 7:7:7::2 dev dummy2 src 1:2:3:4::5 metric 1024 pref medium + ip addr del 1:2:3:4::5/64 dev dummy1 + ip -6 route show 7:7:7::1 dev dummy1 metric 1024 pref medium 7:7:7::2 dev dummy2 src 1:2:3:4::5 metric 1024 pref medium As Ido reminds, in IPv6, the preferred source address is looked up in the same VRF as the first nexthop device, which is different with IPv4. So, while removing the device checking, we also need to add an ipv6_chk_addr() check to make sure the address does not exist on the other devices of the rt nexthop device's VRF. After fix: + ip addr del 1:2:3:4::5/64 dev dummy1 + ip -6 route show 7:7:7::1 dev dummy1 metric 1024 pref medium 7:7:7::2 dev dummy2 metric 1024 pref medium Reported-by:

As the initial commit 1a017276 ("selftests: Add VRF route leaking tests") said, the IPv6 MTU test fails as source address selection picking ::1. Every time we run the selftest this one report failed. There seems not much meaning to keep reporting a failure for 3 years that no one plan to fix/update. Let't just skip this one first. We can add it back when the issue fixed. Signed-off-by:

Setting IP_RECVERR and IPV6_RECVERR options to zero currently purges the socket error queue, which was probably not expected for zerocopy and tx_timestamp users. I discovered this issue while preparing commit 6b5f43ea ("inet: move inet->recverr to inet->inet_flags"), I presume this change does not need to be backported to stable kernels. Add skb_errqueue_purge() helper to purge error messages only. Signed-off-by:

The user ports use RSGMII, but we don't have that, and DT doesn't specify a phy interface mode, so phylib defaults to GMII. These support 1G, 100M and 10M with flow control. It is unknown whether asymetric pause is supported at all speeds. The CPU port uses MII/GMII/RGMII/REVMII by hardware pin strapping, and support speeds specific to each, with full duplex only supported in some modes. Flow control may be supported again by hardware pin strapping, and theoretically is readable through a register but no information is given in the datasheet for that. So, we do a best efforts - and be lenient. Signed-off-by:

Currently any error during render leads to output an empty file. That is quite annoying when using tools/net/ynl/ynl-regen.sh which git greps files with content of "YNL-GEN.." and therefore ignores empty files. So once you fail to regen, you have to checkout the file. Avoid that by rendering to a temporary file first, only at the end copy the content to the actual destination. Signed-off-by:
