| * remoteproc: use struct_size() helperGustavo A. R. Silva2020-01-201-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | One of the more common cases of allocation size calculations is finding the size of a structure that has a zero-sized array at the end, along with memory for some number of elements for that array. For example: struct fw_rsc_vdev { ... struct fw_rsc_vdev_vring vring[0]; } __packed; Make use of the struct_size() helper instead of an open-coded version in order to avoid any potential type mistakes. So, replace the following form: sizeof(*rsc) + rsc->num_of_vrings * sizeof(struct fw_rsc_vdev_vring) with: struct_size(rsc, vring, rsc->num_of_vrings) This code was detected with the help of Coccinelle.

| * remoteproc: Initialize rproc_class before useBrandon Maier2020-01-201-1/+1

However remoteproc drivers need the rproc_class during their probe. If one of the remoteproc drivers runs init and gets through probe before remoteproc_init() runs, a NULL pointer access of rproc_class's `glue_dirs` spinlock occurs. > Unable to handle kernel NULL pointer dereference at virtual address 000000dc > pgd = c0004000 > [000000dc] *pgd=00000000 > Internal error: Oops: 5 [#1] PREEMPT ARM > Modules linked in: > CPU: 0 PID: 1 Comm: swapper Tainted: G W 4.14.106-rt56 #1 > Hardware name: Generic OMAP36xx (Flattened Device Tree) > task: c6050000 task.stack: c604a000 > PC is at rt_spin_lock+0x40/0x6c > LR is at rt_spin_lock+0x28/0x6c > pc : [<c0523c90>] lr : [<c0523c78>] psr: 60000013 > sp : c604bdc0 ip : 00000000 fp : 00000000 > r10: 00000000 r9 : c61c7c10 r8 : c6269c20 > r7 : c0905888 r6 : c6269c20 r5 : 00000000 r4 : 000000d4 > r3 : 000000dc r2 : c6050000 r1 : 00000002 r0 : 000000d4 > Flags: nZCv IRQs on FIQs on Mode SVC_32 ISA ARM Segment none ... > [<c0523c90>] (rt_spin_lock) from [<c03b65a4>] (get_device_parent+0x54/0x17c) > [<c03b65a4>] (get_device_parent) from [<c03b6bec>] (device_add+0xe0/0x5b4) > [<c03b6bec>] (device_add) from [<c042adf4>] (rproc_add+0x18/0xd8) > [<c042adf4>] (rproc_add) from [<c01110e4>] (my_rproc_probe+0x158/0x204) > [<c01110e4>] (my_rproc_probe) from [<c03bb6b8>] (platform_drv_probe+0x34/0x70) > [<c03bb6b8>] (platform_drv_probe) from [<c03b9dd4>] (driver_probe_device+0x2c8/0x420) > [<c03b9dd4>] (driver_probe_device) from [<c03ba02c>] (__driver_attach+0x100/0x11c) > [<c03ba02c>] (__driver_attach) from [<c03b7d08>] (bus_for_each_dev+0x7c/0xc0) > [<c03b7d08>] (bus_for_each_dev) from [<c03b910c>] (bus_add_driver+0x1cc/0x264) > [<c03b910c>] (bus_add_driver) from [<c03ba714>] (driver_register+0x78/0xf8) > [<c03ba714>] (driver_register) from [<c010181c>] (do_one_initcall+0x100/0x190) > [<c010181c>] (do_one_initcall) from [<c0800de8>] (kernel_init_freeable+0x130/0x1d0) > [<c0800de8>] (kernel_init_freeable) from [<c051eee8>] (kernel_init+0x8/0x114) > [<c051eee8>] (kernel_init) from [<c01175b0>] (ret_from_fork+0x14/0x24) > Code: e2843008 e3c2203f f5d3f000 e5922010 (e193cf9f) > ---[ end trace 0000000000000002 ]--- Signed-off-by: Brandon Maier <brandon.maier@rockwellcollins.com> Link: https://lore.kernel.org/r/20190530225223.136420-1-brandon.maier@rockwellcollins.com Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org>

When that happens, all PTEs pointing to the old location are zapped before the move and then faulted in again if needed. When that happens, the page protection caching mode- and encryption bits may change and be different from those of struct vm_area_struct::vm_page_prot. We were using an ugly hack to set the page protection correctly. Fix that and instead export and use vmf_insert_mixed_prot() or use vmf_insert_pfn_prot(). Also get the default page protection from struct vm_area_struct::vm_page_prot rather than using vm_get_page_prot(). This way we catch modifications done by the vm system for drivers that want write-notification.

The interface is provided by including the header 'include/linux/platform_data/cros_ec_proto.h', however, instead of have the implementation of these functions in cros_ec_proto.c, it is in 'cros_ec.c', which is a different kernel module. Apart from being a bad practice, this can induce confusions allowing the users of the cros_ec protocol to call these functions. The register, unregister, suspend, resume and handle_event functions *should* only be called by the different transport drivers (i2c, spi, lpc, etc.), so make this a bit less confusing by moving these functions from the public in-kernel space to a private include in platform/chrome, and then, the interface for cros_ec module and for the cros_ec_proto module is clean.
