2025-03-13wifi: rtw89: refine mechanism of TASKuan-Chung Chen
TAS state switching mechanism now incorporates the TX ratio as a decision parameter. The average power calculation has been improved by using a higher resolution conversion from dBm to linear. During scan or MCC operations, TAS state is forced to static SAR and suspend the average power calculation. Additionally, TAS window size depends on the regulatory domain and band to ensure compliance. TAS is enabled when permitted by the regulatory domain and is currently supported on the 8852CE. For debugging, add a flag to disable_dm that can stop TAS mechanism.

Commit 51bef03e1a71 ("selftests/net: deflake GRO tests") recently switched to NAPI suspension, and lowered the timeout from 1ms to 100us. This started causing flakes in netdev-run CI. Let's bump it to 200us. In a quick test of a debug kernel I see failures with 100us, with 200us in 5 runs I see 2 completely clean runs and 3 with a single retry (GRO test will retry up to 5 times).

2025-03-12net_sched: Prevent creation of classes with TC_H_ROOTCong Wang
The function qdisc_tree_reduce_backlog() uses TC_H_ROOT as a termination condition when traversing up the qdisc tree to update parent backlog counters. However, if a class is created with classid TC_H_ROOT, the traversal terminates prematurely at this class instead of reaching the actual root qdisc, causing parent statistics to be incorrectly maintained. In case of DRR, this could lead to a crash as reported by Mingi Cho. Prevent the creation of any Qdisc class with classid TC_H_ROOT (0xFFFFFFFF) across all qdisc types, as suggested by Jamal.

2025-03-12ipvs: prevent integer overflow in do_ip_vs_get_ctl()Dan Carpenter
The get->num_services variable is an unsigned int which is controlled by the user. The struct_size() function ensures that the size calculation does not overflow an unsigned long, however, we are saving the result to an int so the calculation can overflow. Both "len" and "get->num_services" come from the user. This check is just a sanity check to help the user and ensure they are using the API correctly. An integer overflow here is not a big deal. This has no security impact. Save the result from struct_size() type size_t to fix this integer overflow bug.

2025-03-12netfilter: nf_conncount: Fully initialize struct nf_conncount_tuple in ↵Kohei Enju
insert_tree() Since commit b36e4523d4d5 ("netfilter: nf_conncount: fix garbage collection confirm race"), `cpu` and `jiffies32` were introduced to the struct nf_conncount_tuple. The commit made nf_conncount_add() initialize `conn->cpu` and `conn->jiffies32` when allocating the struct. In contrast, count_tree() was not changed to initialize them. By commit 34848d5c896e ("netfilter: nf_conncount: Split insert and traversal"), count_tree() was split and the relevant allocation code now resides in insert_tree(). Initialize `conn->cpu` and `conn->jiffies32` in insert_tree().

2025-03-11wifi: iwlwifi: mld: avoid selecting bad linksMiri Korenblit
Currently, we don't select a link that wasn't heared in the last 5 seconds. But if the link started to suffer from missed beacons more recent than that, we might select this link even we really shouldn't, leading to a disconnection instead of a link switch. Fix this by checking if a link was heared in the last MLO scan, if not - don't include it in the link selection. Since we do an MLO scan on missed beacons, we will not hear that link in that scan, and won't select it.

According to the requirements, if the last scan isn't older than 20 seconds, we can use its results and do the link selection without scanning before. But this applies only when trying to get back to EMLSR, not if the link has bad RSSI/missed beacons. Since an MLO scan is cheap anyway, and results from 20 seconds before are really old, always scan before links switching.
