Patch "usb: gadget: f_fs: Process all descriptors during bind" has been added to the 4.9-stable tree

During _ffs_func_bind(), the received descriptors are evaluated to prepare for binding with the gadget in order to allocate endpoints and optionally set up OS descriptors. However, the high- and super-speed descriptors are only parsed based on whether the gadget_is_dualspeed() and gadget_is_superspeed() calls are true, respectively. This is a problem in case a userspace program always provides all of the {full,high,super,OS} descriptors when configuring a function. Then, for example if a gadget device is not capable of SuperSpeed, the call to ffs_do_descs() for the SS descriptors is skipped, resulting in an incorrect offset calculation for the vla_ptr when moving on to the OS descriptors that follow. This causes ffs_do_os_descs() to fail as it is now looking at the SS descriptors' offset within the raw_descs buffer instead. _ffs_func_bind() should evaluate the descriptors unconditionally, so remove the checks for gadget speed.

There are 2 control endpoint structures for DWC3. However, the driver only updates the OUT direction control endpoint structure during ConnectDone event. DWC3 driver needs to update the endpoint max packet size for control IN endpoint as well. If the max packet size is not properly set, then the driver will incorrectly calculate the data transfer size and fail to send ZLP for HS/FS 3-stage control read transfer. The fix is simply to update the max packet size for the ep0 IN direction during ConnectDone event.

The fcp_rsp_info structure as defined in the FC spec has an initial 3 bytes reserved field. The ibmvfc driver mistakenly defined this field as 4 bytes resulting in the rsp_code field being defined in what should be the start of the second reserved field and thus always being reported as zero by the driver. Ideally, we should wire ibmvfc up with libfc for the sake of code deduplication, and ease of maintaining standardized structures in a single place. However, for now simply fixup the definition in ibmvfc for backporting to distros on older kernels. Wiring up with libfc will be done in a followup patch.

When pkcs7_verify_sig_chain() is building the certificate chain for a SignerInfo using the certificates in the PKCS#7 message, it is passing the wrong arguments to public_key_verify_signature(). Consequently, when the next certificate is supposed to be used to verify the previous certificate, the next certificate is actually used to verify itself. An attacker can use this bug to create a bogus certificate chain that has no cryptographic relationship between the beginning and end. Fortunately I couldn't quite find a way to use this to bypass the overall signature verification, though it comes very close. Here's the reasoning: due to the bug, every certificate in the chain beyond the first actually has to be self-signed (where "self-signed" here refers to the actual key and signature; an attacker might still manipulate the certificate fields such that the self_signed flag doesn't actually get set, and thus the chain doesn't end immediately). But to pass trust validation (pkcs7_validate_trust()), either the SignerInfo or one of the certificates has to actually be signed by a trusted key. Since only self-signed certificates can be added to the chain, the only way for an attacker to introduce a trusted signature is to include a self-signed trusted certificate. But, when pkcs7_validate_trust_one() reaches that certificate, instead of trying to verify the signature on that certificate, it will actually look up the corresponding trusted key, which will succeed, and then try to verify the *previous* certificate, which will fail. Thus, disaster is narrowly averted (as far as I could tell).

Patch "PCI/cxgb4: Extend T3 PCI quirk to T4+ devices" has been added to the 4.9-stable tree

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled PCI/cxgb4: Extend T3 PCI quirk to T4+ devices to the 4.9-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=sum… The filename of the patch is: pci-cxgb4-extend-t3-pci-quirk-to-t4-devices.patch and it can be found in the queue-4.9 subdirectory.

We've run into a problem where our device is attached to a Virtual Machine and the use of the new pci_set_vpd_size() API doesn't help. The VM kernel has been informed that the accesses are okay, but all of the actual VPD Capability Accesses are trapped down into the KVM Hypervisor where it goes ahead and imposes the silent denials. The right idea is to follow the kernel.org commit 1c7de2b4ff88 ("PCI: Enable access to non-standard VPD for Chelsio devices (cxgb3)") which Alexey Kardashevskiy authored to establish a PCI Quirk for our T3-based adapters. This commit extends that PCI Quirk to cover Chelsio T4 devices and later. The advantage of this approach is that the VPD Size gets set early in the Base OS/Hypervisor Boot and doesn't require that the cxgb4 driver even be available in the Base OS/Hypervisor. Thus PF4 can be exported to a Virtual Machine and everything should work.

Patch "ohci-hcd: Fix race condition caused by ohci_urb_enqueue() and io_watchdog_func()" has been added to the 4.9-stable tree

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled ohci-hcd: Fix race condition caused by ohci_urb_enqueue() and io_watchdog_func() to the 4.9-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=sum… The filename of the patch is: ohci-hcd-fix-race-condition-caused-by-ohci_urb_enqueue-and-io_watchdog_func.patch and it can be found in the queue-4.9 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable(a)vger.kernel.org> know about it. >From b2685bdacdaab065c172b97b55ab46c6be77a037 Mon Sep 17 00:00:00 2001 From: Shigeru Yoshida <shigeru.yoshida(a)windriver.com> Date: Fri, 2 Feb 2018 13:51:39 +0800 Subject: ohci-hcd: Fix race condition caused by ohci_urb_enqueue() and io_watchdog_func() From: Shigeru Yoshida <shigeru.yoshida(a)windriver.com> commit b2685bdacdaab065c172b97b55ab46c6be77a037 upstream. Running io_watchdog_func() while ohci_urb_enqueue() is running can cause a race condition where ohci->prev_frame_no is corrupted and the watchdog can mis-detect following error: ohci-platform 664a0800.usb: frame counter not updating; disabled ohci-platform 664a0800.usb: HC died; cleaning up Specifically, following scenario causes a race condition: 1. ohci_urb_enqueue() calls spin_lock_irqsave(&ohci->lock, flags) and enters the critical section 2. ohci_urb_enqueue() calls timer_pending(&ohci->io_watchdog) and it returns false 3. ohci_urb_enqueue() sets ohci->prev_frame_no to a frame number read by ohci_frame_no(ohci) 4. ohci_urb_enqueue() schedules io_watchdog_func() with mod_timer() 5. ohci_urb_enqueue() calls spin_unlock_irqrestore(&ohci->lock, flags) and exits the critical section 6. Later, ohci_urb_enqueue() is called 7. ohci_urb_enqueue() calls spin_lock_irqsave(&ohci->lock, flags) and enters the critical section 8. The timer scheduled on step 4 expires and io_watchdog_func() runs 9. io_watchdog_func() calls spin_lock_irqsave(&ohci->lock, flags) and waits on it because ohci_urb_enqueue() is already in the critical section on step 7 10. ohci_urb_enqueue() calls timer_pending(&ohci->io_watchdog) and it returns false 11. ohci_urb_enqueue() sets ohci->prev_frame_no to new frame number read by ohci_frame_no(ohci) because the frame number proceeded between step 3 and 6 12. ohci_urb_enqueue() schedules io_watchdog_func() with mod_timer() 13. ohci_urb_enqueue() calls spin_unlock_irqrestore(&ohci->lock, flags) and exits the critical section, then wake up io_watchdog_func() which is waiting on step 9 14. io_watchdog_func() enters the critical section 15. io_watchdog_func() calls ohci_frame_no(ohci) and set frame_no variable to the frame number 16. io_watchdog_func() compares frame_no and ohci->prev_frame_no On step 16, because this calling of io_watchdog_func() is scheduled on step 4, the frame number set in ohci->prev_frame_no is expected to the number set on step 3. However, ohci->prev_frame_no is overwritten on step 11. Because step 16 is executed soon after step 11, the frame number might not proceed, so ohci->prev_frame_no must equals to frame_no. To address above scenario, this patch introduces a special sentinel value IO_WATCHDOG_OFF and set this value to ohci->prev_frame_no when the watchdog is not pending or running. When ohci_urb_enqueue() schedules the watchdog (step 4 and 12 above), it compares ohci->prev_frame_no to IO_WATCHDOG_OFF so that ohci->prev_frame_no is not overwritten while io_watchdog_func() is running.
