treewide: refresh kmalloc_obj() conversions

2026-09-05T04:37:00+00:00

This is another run of the Coccinelle script for converting kmalloc() family of allocations to kmalloc_obj() via the existing rules in scripts/coccinelle/api/kmalloc_objs.cocci This catches both the set of kmalloc() uses added since the first kmalloc_obj() conversions in v7.0 and adds a large group missed in the first pass due to Coccinelle not interacting well with the cleanup.h scoped_...() family of macros[1]. I worked around this with spatch's "--macro-file" argument to a file with all the scoped_...() macros mapped to Coccinelle's YACFE_ITERATOR[2] as that was the closest viable control flow indicator I could find. Build tested allmodconfig on x86, arm64, arm, loongarch, mips, powerpc, riscv, and s390 with no new warnings.

power: sequencing: rename pwrseq_power_on/off() to pwrseq_enable/disable()

2026-08-26T08:05:45+00:00

The way power sequencing works means that a call to pwrseq_power_on() does not necessarily result in the pwrseq target being powered-on at that time: it may have already been powered on before. Similarly: a call to pwrseq_power_off() does not have to result in an actual powering off of resources: there may still be other users that requested a power-on before. We will also introduce the concept of "non-controllable" pwrseq targets soon which further increases the disconnect between the naming convention and the actual semantics. What consumers of pwrseq descriptors actually do is: they *vote* for a powering on of a given target or retract that vote. These operations could be called get/put in line with runtime PM but this could become confusing since we already provide pwrseq_get/put() for a different purpose. pwrseq_vote_on/off() also have been rejected as unusual in the tree. Change the name of the two functions to pwrseq_enable/disable() which better reflects their purpose and semantics and also mirrors other enable-counted resources like regulators and clocks. No functional change intended. If at any point users need to know *when* the exact power event happens, we can provide that information in the form of a notifier.

wifi: cfg80211: convert cookie output to input parameter

2026-08-02T15:40:08+00:00

The remain_on_channel, mgmt_tx, and probe_peer ops previously used a u64 *cookie output parameter. Now that cfg80211 pre-assigns the cookie value before invoking drivers, the parameter conveys a value from caller to driver, not the other way around. Convert it to a plain u64 input parameter across the ops struct (cfg80211.h), rdev-ops.h wrappers, nl80211.c/mlme.c call sites, mac80211, and all driver implementations. The tx_control_port op is excluded: its cookie pointer is nullable (passed as NULL when dont_wait_for_ack is set), so the nullable pointer semantics are still required. Internal mac80211 helpers ieee80211_start_roc_work() and ieee80211_attach_ack_skb() still take u64 *cookie because they assign to the pointee; their callers now pass &cookie to take the address of the local value parameter. wil6210's internal wil_p2p_listen() is also updated to take u64 cookie since it is called directly from the remain_on_channel callback.

wifi: wil6210: use pre-assigned cookie for remain_on_channel, mgmt_tx and probe_peer

2026-08-02T15:40:07+00:00

Stop overwriting the pre-assigned cookie in wil_p2p_listen(), wil_cfg80211_mgmt_tx(), and wil_cfg80211_probe_peer(). For remain_on_channel, store the pre-assigned cookie in p2p->cookie instead of incrementing it. All cancel and expiry callbacks already read from p2p->cookie so they pick up the correct value. For mgmt_tx, remove the defensive "cookie ? *cookie : 0" guard; cfg80211 guarantees a non-NULL cookie pointer. For probe_peer, store the pre-assigned cookie in req->cookie instead of the CID value. The CID is still available via req->cid for STA lookup in wil_probe_client_handle().

wifi: ath6kl: use pre-assigned cookie for remain_on_channel and mgmt_tx

2026-08-02T15:40:06+00:00

Stop generating cookies in ath6kl_remain_on_channel() and ath6kl_mgmt_tx(). cfg80211 now pre-assigns the cookie before calling into the driver. For remain_on_channel, store the pre-assigned cookie in vif->last_roc_id. Widen last_roc_id and last_cancel_roc_id from u32 to u64 to hold the full 64-bit cookie value. For mgmt_tx, store the pre-assigned cookie in wmi->last_mgmt_tx_cookie so the firmware TX status event handler can pass the correct cookie to cfg80211_mgmt_tx_status(). Thread the cookie through the powersave queue (ath6kl_mgmt_buff) so it is available when the frame is eventually dequeued and sent.
