2021-08-09dma-mapping: allow map_sg() ops to return negative error codesLogan Gunthorpe
Allow dma_map_sgtable() to pass errors from the map_sg() ops. This will be required for returning appropriate error codes when mapping P2PDMA memory. Introduce __dma_map_sg_attrs() which will return the raw error code from the map_sg operation (whether it be negative or zero). Then add a dma_map_sg_attrs() wrapper to convert any negative errors to zero to satisfy the existing calling convention. dma_map_sgtable() defines three error codes that .map_sg implementations are allowed to return: -EINVAL, -ENOMEM and -EIO. The latter of which is a generic return for cases that are passing DMA_MAPPING_ERROR through. dma_map_sgtable() will convert a zero error return for old map_sg() ops into a -EIO return and return any negative errors as reported. This allows map_sg implementations to start returning multiple negative error codes. Legacy map_sg implementations can continue to return zero until they are all converted.

2021-08-09dma-debug: fix debugfs initialization orderAnthony Iliopoulos
Due to link order, dma_debug_init is called before debugfs has a chance to initialize (via debugfs_init which also happens in the core initcall stage), so the directories for dma-debug are never created. Decouple dma_debug_fs_init from dma_debug_init and defer its init until core_initcall_sync (after debugfs has been initialized) while letting dma-debug initialization occur as soon as possible to catch any early mappings, as suggested in [1].

2021-08-06riscv: Get rid of CONFIG_PHYS_RAM_BASE in kernel physical address conversionAlexandre Ghiti
The usage of CONFIG_PHYS_RAM_BASE for all kernel types was a mistake: this value is implementation-specific and this breaks the genericity of the RISC-V kernel. Fix this by introducing a new variable phys_ram_base that holds this value at runtime and use it in the kernel physical address conversion macro. Since this value is used only for XIP kernels, evaluate it only if CONFIG_XIP_KERNEL is set which in addition optimizes this macro for standard kernels at compile-time.

git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace Pull tracing fixes from Steven Rostedt: "Fix tracepoint race between static_call and callback data As callbacks to a tracepoint are paired with the data that is passed in when the callback is registered to the tracepoint, it must have that data passed to the callback when the tracepoint is triggered, else bad things will happen. To keep the two together, they are both assigned to a tracepoint structure and added to an array. The tracepoint call site will dereference the structure (via RCU) and call the callback in that structure along with the data in that structure. This keeps the callback and data tightly coupled. Because of the overhead that retpolines have on tracepoint callbacks, if there's only one callback attached to a tracepoint (a common case), then it is called via a static call (code modified to do a direct call instead of an indirect call). But to implement this, the data had to be decoupled from the callback, as now the callback is implemented via a direct call from the static call and not an indirect call from the dereferenced structure. Note, the static call only calls a callback used when there's a single callback attached to the tracepoint. If more than one callback is attached to the same tracepoint, then the static call will call an iterator function that goes back to dereferencing the structure keeping the callback and its data tightly coupled again. Issues can arise when going from 0 callbacks to one, as the static call is assigned to the callback, and it must take care that the data passed to it is loaded before the static call calls the callback. Going from 1 to 2 callbacks is not an issue, as long as the static call is updated to the iterator before the tracepoint structure array is updated via RCU. Going from 2 to more or back down to 2 is not an issue as the iterator can handle all theses cases. But going from 2 to 1, care must be taken as the static call is now calling a callback and the data that is loaded must be the data for that callback. Care was taken to ensure the callback and data would be in-sync, but after a bug was reported, it became clear that not enough was done to make sure that was the case. These changes address this. The first change is to compare the old and new data instead of the old and new callback, as it's the data that can corrupt the callback, even if the callback is the same (something getting freed). The next change is to convert these transitions into states, to make it easier to know when a synchronization is needed, and to perform those synchronizations. The problem with this patch is that it slows down disabling all events from under a second, to making it take over 10 seconds to do the same work. But that is addressed in the final patch. The final patch uses the RCU state functions to keep track of the RCU state between the transitions, and only needs to perform the synchronization if an RCU synchronization hasn't been done already. This brings the performance of disabling all events back to its original value. That's because no synchronization is required between disabling tracepoints but is required when enabling a tracepoint after its been disabled. If an RCU synchronization happens after the tracepoint is disabled, and before it is re-enabled, there's no need to do the synchronization again. Both the second and third patch have subtle complexities that they are separated into two patches. But because the second patch causes such a regression in performance, the third patch adds a "Fixes" tag to the second patch, such that the two must be backported together and not just the second patch" * tag 'trace-v5.14-rc4-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: tracepoint: Use rcu get state and cond sync for static call updates tracepoint: Fix static call function vs data state mismatch tracepoint: static call: Compare data on transition from 2->1 callees

2021-08-06tracepoint: Use rcu get state and cond sync for static call updatesMathieu Desnoyers
State transitions from 1->0->1 and N->2->1 callbacks require RCU synchronization. Rather than performing the RCU synchronization every time the state change occurs, which is quite slow when many tracepoints are registered in batch, instead keep a snapshot of the RCU state on the most recent transitions which belong to a chain, and conditionally wait for a grace period on the last transition of the chain if one g.p. has not elapsed since the last snapshot. This applies to both RCU and SRCU. This brings the performance regression caused by commit 231264d6927f ("Fix: tracepoint: static call function vs data state mismatch") back to what it was originally.

2021-08-06io-wq: fix no lock protection of acct->nr_workerHao Xu
There is an acct->nr_worker visit without lock protection. Think about the case: two callers call io_wqe_wake_worker(), one is the original context and the other one is an io-worker(by calling io_wqe_enqueue(wqe, linked)), on two cpus paralelly, this may cause nr_worker to be larger than max_worker. Let's fix it by adding lock for it, and let's do nr_workers++ before create_io_worker. There may be a edge cause that the first caller fails to create an io-worker, but the second caller doesn't know it and then quit creating io-worker as well: say nr_worker = max_worker - 1 cpu 0 cpu 1 io_wqe_wake_worker() io_wqe_wake_worker() nr_worker < max_worker nr_worker++ create_io_worker() nr_worker == max_worker failed return return But the chance of this case is very slim.

2021-08-05RDMA/iw_cxgb4: Fix refcount underflow while destroying cqs.Dakshaja Uppalapati
Previous atomic increment/decrement logic expects the atomic count to be '0' after the final decrement. Replacing atomic count with refcount does not allow that, as refcount_dec() considers count of 1 as underflow and triggers a kernel splat. Fix the current refcount logic by using the usual pattern of decrementing the refcount and test if it is '0' on the final deref in c4iw_destroy_cq(). Use wait_for_completion() instead of wait_event().

2021-08-05tracepoint: Fix static call function vs data state mismatchMathieu Desnoyers
On a 1->0->1 callbacks transition, there is an issue with the new callback using the old callback's data. Considering __DO_TRACE_CALL: do { \ struct tracepoint_func *it_func_ptr; \ void *__data; \ it_func_ptr = \ rcu_dereference_raw((&__tracepoint_##name)->funcs); \ if (it_func_ptr) { \ __data = (it_func_ptr)->data; \ ----> [ delayed here on one CPU (e.g. vcpu preempted by the host) ] static_call(tp_func_##name)(__data, args); \ } \ } while (0) It has loaded the tp->funcs of the old callback, so it will try to use the old data. This can be fixed by adding a RCU sync anywhere in the 1->0->1 transition chain. On a N->2->1 transition, we need an rcu-sync because you may have a sequence of 3->2->1 (or 1->2->1) where the element 0 data is unchanged between 2->1, but was changed from 3->2 (or from 1->2), which may be observed by the static call. This can be fixed by adding an unconditional RCU sync in transition 2->1. Note, this fixes a correctness issue at the cost of adding a tremendous performance regression to the disabling of tracepoints. Before this commit: # trace-cmd start -e all # time trace-cmd start -p nop real 0m0.778s user 0m0.000s sys 0m0.061s After this commit: # trace-cmd start -e all # time trace-cmd start -p nop real 0m10.593s user 0m0.017s sys 0m0.259s A follow up fix will introduce a more lightweight scheme based on RCU get_state and cond_sync, that will return the performance back to what it was. As both this change and the lightweight versions are complex on their own, for bisecting any issues that this may cause, they are kept as two separate changes.
