Pull char/misc/iio driver fixes from Greg KH: "Here are a relativly large number of small char/misc/iio and other driver fixes for 7.0-rc7. There's a bunch, but overall they are all small fixes for issues that people have been having that I finally caught up with getting merged due to delays on my end. The "largest" change overall is just some documentation updates to the security-bugs.rst file to hopefully tell the AI tools (and any users that actually read the documentation), how to send us better security bug reports as the quantity of reports these past few weeks has increased dramatically due to tools getting better at "finding" things. Included in here are: - lots of small IIO driver fixes for issues reported in 7.0-rc - gpib driver fixes - comedi driver fixes - interconnect driver fix - nvmem driver fixes - mei driver fix - counter driver fix - binder rust driver fixes - some other small misc driver fixes All of these have been in linux-next this week with no reported issues" * tag 'char-misc-7.0-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc: (63 commits) Documentation: fix two typos in latest update to the security report howto Documentation: clarify the mandatory and desirable info for security reports Documentation: explain how to find maintainers addresses for security reports Documentation: minor updates to the security contacts .get_maintainer.ignore: add myself nvmem: zynqmp_nvmem: Fix buffer size in DMA and memcpy nvmem: imx: assign nvmem_cell_info::raw_len misc: fastrpc: check qcom_scm_assign_mem() return in rpmsg_probe misc: fastrpc: possible double-free of cctx->remote_heap comedi: dt2815: add hardware detection to prevent crash comedi: runflags cannot determine whether to reclaim chanlist comedi: Reinit dev->spinlock between attachments to low-level drivers comedi: me_daq: Fix potential overrun of firmware buffer comedi: me4000: Fix potential overrun of firmware buffer comedi: ni_atmio16d: Fix invalid clean-up after failed attach gpib: fix use-after-free in IO ioctl handlers gpib: lpvo_usb: fix memory leak on disconnect gpib: Fix fluke driver s390 compile issue lis3lv02d: Omit IRQF_ONESHOT if no threaded handler is provided lis3lv02d: fix kernel-doc warnings ...

Pull USB/Thunderbolt fixes from Greg KH: "Here are a bunch of USB and Thunderbolt fixes (most all are USB) for 7.0-rc7. More than I normally like this late in the release cycle, partly due to my recent travels, and partly due to people banging away on the USB gadget interfaces and apis more than normal (big shoutout to Android for getting the vendors to actually work upstream on this, that's a huge win overall for everyone here) Included in here are: - Small thunderbolt fix - new USB serial driver ids added - typec driver fixes - gadget driver fixes for some disconnect issues - other usb gadget driver fixes for reported problems with binding and unbinding devices as happens when a gadget device connects / disconnects from a system it is plugged into (or it switches device mode at a user's request, these things are complex little beasts...) - usb offload fixes (where USB audio tunnels through the controller while the main CPU is asleep) for when EMP spikes hit the system causing disconnects to happen (as often happens with static electricity in the winter months). This has been much reported by at least one vendor, and resolves the issues they have been seeing with this codepath. Can't wait for the "formal methods are the answer!" people to try to model that one properly... - Other small usb driver fixes for issues reported.

usb: core: use dedicated spinlock for offload state

2026-04-02T07:43:26+00:00

Replace the coarse USB device lock with a dedicated offload_lock spinlock to reduce contention during offload operations. Use offload_pm_locked to synchronize with PM transitions and replace the legacy offload_at_suspend flag. Optimize usb_offload_get/put by switching from auto-resume/suspend to pm_runtime_get_if_active(). This ensures offload state is only modified when the device is already active, avoiding unnecessary power transitions.

bpf: Fix grace period wait for tracepoint bpf_link

2026-03-31T23:01:13+00:00

Recently, tracepoints were switched from using disabled preemption (which acts as RCU read section) to SRCU-fast when they are not faultable. This means that to do a proper grace period wait for programs running in such tracepoints, we must use SRCU's grace period wait. This is only for non-faultable tracepoints, faultable ones continue using RCU Tasks Trace. However, bpf_link_free() currently does call_rcu() for all cases when the link is non-sleepable (hence, for tracepoints, non-faultable). Fix this by doing a call_srcu() grace period wait. As far RCU Tasks Trace gp -> RCU gp chaining is concerned, it is deemed unnecessary for tracepoint programs. The link and program are either accessed under RCU Tasks Trace protection, or SRCU-fast protection now. The earlier logic of chaining both RCU Tasks Trace and RCU gp waits was to generalize the logic, even if it conceded an extra RCU gp wait, however that is unnecessary for tracepoints even before this change. In practice no cost was paid since rcu_trace_implies_rcu_gp() was always true. Hence we need not chaining any RCU gp after the SRCU gp. For instance, in the non-faultable raw tracepoint, the RCU read section of the program in __bpf_trace_run() is enclosed in the SRCU gp, likewise for faultable raw tracepoint, the program is under the RCU Tasks Trace protection. Hence, the outermost scope can be waited upon to ensure correctness. Also, sleepable programs cannot be attached to non-faultable tracepoints, so whenever program or link is sleepable, only RCU Tasks Trace protection is being used for the link and prog.
