[PATCH] powerpc/85xx: fix compile error without CONFIG_CRASH_DUMP

by Hari Bathini

Since commit 5c4233cc0920 ("powerpc/kdump: Split KEXEC_CORE and CRASH_DUMP dependency"), crashing_cpu is not available without CONFIG_CRASH_DUMP. Fix compile error on 64-BIT 85xx owing to this change.

There is a scenario where the FFS application issues an AIO cancel call, while the UDC is handling a soft disconnect. For a DWC3 based implementation, the callstack looks like the following: DWC3 Gadget FFS Application dwc3_gadget_soft_disconnect() ... --> dwc3_stop_active_transfers() --> dwc3_gadget_giveback(-ESHUTDOWN) --> ffs_epfile_async_io_complete() ffs_aio_cancel() --> usb_ep_free_request() --> usb_ep_dequeue() There is currently no locking implemented between the AIO completion handler and AIO cancel, so the issue occurs if the completion routine is running in parallel to an AIO cancel call coming from the FFS application. As the completion call frees the USB request (io_data->req) the FFS application is also referencing it for the usb_ep_dequeue() call. This can lead to accessing a stale/hanging pointer. commit b566d38857fc ("usb: gadget: f_fs: use io_data->status consistently") relocated the usb_ep_free_request() into ffs_epfile_async_io_complete(). However, in order to properly implement locking to mitigate this issue, the spinlock can't be added to ffs_epfile_async_io_complete(), as usb_ep_dequeue() (if successfully dequeuing a USB request) will call the function driver's completion handler in the same context. Hence, leading into a deadlock. Fix this issue by moving the usb_ep_free_request() back to ffs_user_copy_worker(), and ensuring that it explicitly sets io_data->req to NULL after freeing it within the ffs->eps_lock. This resolves the race condition above, as the ffs_aio_cancel() routine will not continue attempting to dequeue a request that has already been freed, or the ffs_user_copy_work() not freeing the USB request until the AIO cancel is done referencing it.

However, in order to properly implement locking to mitigate this issue, the spinlock can't be added to ffs_epfile_async_io_complete(), as usb_ep_dequeue() (if successfully dequeuing a USB request) will call the function driver's completion handler in the same context. Hence, leading into a deadlock. Fix this issue by moving the usb_ep_free_request() back to ffs_user_copy_worker(), and ensuring that it explicitly sets io_data->req to NULL after freeing it within the ffs->eps_lock. This resolves the race condition above, as the ffs_aio_cancel() routine will not continue attempting to dequeue a request that has already been freed, or the ffs_user_copy_work() not freeing the USB request until the AIO cancel is done referencing it. This fix depends on commit b566d38857fc ("usb: gadget: f_fs: use io_data->status consistently") Fixes: 2e4c7553cd6f ("usb: gadget: f_fs: add aio support") Cc: stable <stable(a)kernel.org> # b566d38857fc ("usb: gadget: f_fs: use io_data->status consistently") Signed-off-by: Wesley Cheng <quic_wcheng(a)quicinc.com> Link: https://lore.kernel.org/r/20240409014059.6740-1-quic_wcheng@quicinc.com Signed-off-by: Greg Kroah-Hartman <gregkh(a)linuxfoundation.org> diff --git a/drivers/usb/gadget/function/f_fs.c b/drivers/usb/gadget/function/f_fs.c index f855f1fc8e5e..aa80c2a6b8e0 100644 --- a/drivers/usb/gadget/function/f_fs.c +++ b/drivers/usb/gadget/function/f_fs.c @@ -852,6 +852,7 @@ static void ffs_user_copy_worker(struct work_struct *work) work); int ret = io_data->status; bool kiocb_has_eventfd = io_data->kiocb->ki_flags & IOCB_EVENTFD; + unsigned long flags; if (io_data->read && ret > 0) { kthread_use_mm(io_data->mm); @@ -864,6 +865,11 @@ static void ffs_user_copy_worker(struct work_struct *work) if (io_data->ffs->ffs_eventfd && !kiocb_has_eventfd) eventfd_signal(io_data->ffs->ffs_eventfd); + spin_lock_irqsave(&io_data->ffs->eps_lock, flags); + usb_ep_free_request(io_data->ep, io_data->req); + io_data->req = NULL; + spin_unlock_irqrestore(&io_data->ffs->eps_lock, flags); + if (io_data->read) kfree(io_data->to_free); ffs_free_buffer(io_data); @@ -877,7 +883,6 @@ static void ffs_epfile_async_io_complete(struct usb_ep *_ep, struct ffs_data *ffs = io_data->ffs; io_data->status = req->status ? req->status : req->actual; - usb_ep_free_request(_ep, req); INIT_WORK(&io_data->work, ffs_user_copy_worker); queue_work(ffs->io_completion_wq, &io_data->work);

4.19 stable kernel crash caused by vxlan testing

by zhulei

Hey all, I recently used a testing program to test the 4.19 stable branch kernel and found that a crash occurred immediately. The test source code link is: https://github.com/Backmyheart/src0358/blob/master/vxlan_fdb_destroy.c The test command is as follows: gcc vxlan_fdb_destroy.c -o vxlan_fdb_destroy -lpthread According to its stack, upstream has relevant repair patch, the commit id is 7c31e54aeee517d1318dfc0bde9fa7de75893dc6. May i ask if the 4.19 kernel will port this patch ?
