[PATCH] drm/i915: Fix use-after-free due to intel_context_pin/unpin race

by Sultan Alsawaf

From: Sultan Alsawaf <sultan(a)kerneltoast.com> The retire and active callbacks can run simultaneously, allowing intel_context_pin() and intel_context_unpin() to run at the same time, trashing the ring and page tables. In 5.4, this was more noticeable because intel_ring_unpin() would set ring->vaddr to NULL and cause a clean NULL-pointer-dereference panic, but in newer kernels the use-after-free goes unnoticed. The NULL-pointer-dereference looks like this: BUG: unable to handle page fault for address: 0000000000003448 RIP: 0010:gen8_emit_flush_render+0x163/0x190 Call Trace: execlists_request_alloc+0x25/0x40 __i915_request_create+0x1f4/0x2c0 i915_request_create+0x71/0xc0 i915_gem_do_execbuffer+0xb98/0x1a80 ? preempt_count_add+0x68/0xa0 ? _raw_spin_lock+0x13/0x30 ? _raw_spin_unlock+0x16/0x30 i915_gem_execbuffer2_ioctl+0x1de/0x3c0 ? i915_gem_busy_ioctl+0x7f/0x1d0 ? i915_gem_execbuffer_ioctl+0x2d0/0x2d0 drm_ioctl_kernel+0xb2/0x100 drm_ioctl+0x209/0x360 ? i915_gem_execbuffer_ioctl+0x2d0/0x2d0 ksys_ioctl+0x87/0xc0 __x64_sys_ioctl+0x16/0x20 do_syscall_64+0x4e/0x150 entry_SYSCALL_64_after_hwframe+0x44/0xa9 Protect the retire callback with ref->mutex to complement the active callback and fix the corruption.

patch "xhci: Don't clear hub TT buffer on ep0 protocol stall" added to usb-linus

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled xhci: Don't clear hub TT buffer on ep0 protocol stall to my usb git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git in the usb-linus branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will hopefully also be merged in Linus's tree for the next -rc kernel release. If you have any questions about this process, please let me know. >From 8f97250c21f0cf36434bf5b7ddf4377406534cd1 Mon Sep 17 00:00:00 2001 From: Mathias Nyman <mathias.nyman(a)linux.intel.com> Date: Tue, 21 Apr 2020 17:08:22 +0300 Subject: xhci: Don't clear hub TT buffer on ep0 protocol stall The default control endpoint ep0 can return a STALL indicating the device does not support the control transfer requests. This is called a protocol stall and does not halt the endpoint. xHC behaves a bit different. Its internal endpoint state will always be halted on any stall, even if the device side of the endpiont is not halted. So we do need to issue the reset endpoint command to clear the xHC host intenal endpoint halt state, but should not request the HS hub to clear the TT buffer unless device side of endpoint is halted. Clearing the hub TT buffer at protocol stall caused ep0 to become unresponsive for some FS/LS devices behind HS hubs, and class drivers failed to set the interface due to timeout: usb 1-2.1: 1:1: usb_set_interface failed (-110) Fixes: ef513be0a905 ("usb: xhci: Add Clear_TT_Buffer") Cc: <stable(a)vger.kernel.org> # v5.3 Signed-off-by: Mathias Nyman <mathias.nyman(a)linux.intel.com> Link: https://lore.kernel.org/r/20200421140822.28233-4-mathias.nyman@linux.intel.… Signed-off-by: Greg Kroah-Hartman <gregkh(a)linuxfoundation.org> --- drivers/usb/host/xhci-ring.c | 16 +++++++++++----- 1 file changed, 11 insertions(+), 5 deletions(-) diff --git a/drivers/usb/host/xhci-ring.c b/drivers/usb/host/xhci-ring.c index a7f4cd35da55..0fda0c0f4d31 100644 --- a/drivers/usb/host/xhci-ring.c +++ b/drivers/usb/host/xhci-ring.c @@ -1876,7 +1876,6 @@ static void xhci_cleanup_halted_endpoint(struct xhci_hcd *xhci, ep->ep_state |= EP_HARD_CLEAR_TOGGLE; xhci_cleanup_stalled_ring(xhci, slot_id, ep_index, stream_id, td); - xhci_clear_hub_tt_buffer(xhci, td, ep); } xhci_ring_cmd_db(xhci); } @@ -1997,11 +1996,18 @@ static int finish_td(struct xhci_hcd *xhci, struct xhci_td *td, if (trb_comp_code == COMP_STALL_ERROR || xhci_requires_manual_halt_cleanup(xhci, ep_ctx, trb_comp_code)) { - /* Issue a reset endpoint command to clear the host side - * halt, followed by a set dequeue command to move the - * dequeue pointer past the TD. - * The class driver clears the device side halt later. + /* + * xhci internal endpoint state will go to a "halt" state for + * any stall, including default control pipe protocol stall. + * To clear the host side halt we need to issue a reset endpoint + * command, followed by a set dequeue command to move past the + * TD. + * Class drivers clear the device side halt from a functional + * stall later.

This halted endpoint was not handled correctly by xhci driver as events on empty rings were all assumed to be spurious events. xhci driver refused to restart the ring with EP_HALTED flag set, so class driver was never informed the endpoint halted even if it queued new URBs. The host side of the endpoint needs to be reset, and dequeue pointer should be moved in order to clear the cached TRBs and resetart the endpoint. Small adjustments in finding the new dequeue pointer are needed to support the case of stall on an empty ring and unknown current TD.

[PATCH 3/3] xhci: Don't clear hub TT buffer on ep0 protocol stall

by Mathias Nyman

The default control endpoint ep0 can return a STALL indicating the device does not support the control transfer requests. This is called a protocol stall and does not halt the endpoint. xHC behaves a bit different. Its internal endpoint state will always be halted on any stall, even if the device side of the endpiont is not halted. So we do need to issue the reset endpoint command to clear the xHC host intenal endpoint halt state, but should not request the HS hub to clear the TT buffer unless device side of endpoint is halted. Clearing the hub TT buffer at protocol stall caused ep0 to become unresponsive for some FS/LS devices behind HS hubs, and class drivers failed to set the interface due to timeout: usb 1-2.1: 1:1: usb_set_interface failed (-110) Fixes: ef513be0a905 ("usb: xhci: Add Clear_TT_Buffer") Cc: <stable(a)vger.kernel.org> # v5.3 Signed-off-by: Mathias Nyman <mathias.nyman(a)linux.intel.com> --- drivers/usb/host/xhci-ring.c | 16 +++++++++++----- 1 file changed, 11 insertions(+), 5 deletions(-) diff --git a/drivers/usb/host/xhci-ring.c b/drivers/usb/host/xhci-ring.c index a7f4cd35da55..0fda0c0f4d31 100644 --- a/drivers/usb/host/xhci-ring.c +++ b/drivers/usb/host/xhci-ring.c @@ -1876,7 +1876,6 @@ static void xhci_cleanup_halted_endpoint(struct xhci_hcd *xhci, ep->ep_state |= EP_HARD_CLEAR_TOGGLE; xhci_cleanup_stalled_ring(xhci, slot_id, ep_index, stream_id, td); - xhci_clear_hub_tt_buffer(xhci, td, ep); } xhci_ring_cmd_db(xhci); } @@ -1997,11 +1996,18 @@ static int finish_td(struct xhci_hcd *xhci, struct xhci_td *td, if (trb_comp_code == COMP_STALL_ERROR || xhci_requires_manual_halt_cleanup(xhci, ep_ctx, trb_comp_code)) { - /* Issue a reset endpoint command to clear the host side - * halt, followed by a set dequeue command to move the - * dequeue pointer past the TD. - * The class driver clears the device side halt later. + /* + * xhci internal endpoint state will go to a "halt" state for + * any stall, including default control pipe protocol stall. + * To clear the host side halt we need to issue a reset endpoint + * command, followed by a set dequeue command to move past the + * TD. + * Class drivers clear the device side halt from a functional + * stall later.
