2019-04-19net/mlx5e: Fix use-after-free after xdp_return_frameMaxim Mikityanskiy
xdp_return_frame releases the frame. It leads to releasing the page, so it's not allowed to access xdpi.xdpf->len after that, because xdpi.xdpf is at xdp->data_hard_start after convert_to_xdp_frame. This patch moves the memory access to precede the return of the frame.

2019-04-19USB: core: Fix bug caused by duplicate interface PM usage counterAlan Stern
The syzkaller fuzzer reported a bug in the USB hub driver which turned out to be caused by a negative runtime-PM usage counter. This allowed a hub to be runtime suspended at a time when the driver did not expect it. The symptom is a WARNING issued because the hub's status URB is submitted while it is already active: URB 0000000031fb463e submitted while active WARNING: CPU: 0 PID: 2917 at drivers/usb/core/urb.c:363 The negative runtime-PM usage count was caused by an unfortunate design decision made when runtime PM was first implemented for USB. At that time, USB class drivers were allowed to unbind from their interfaces without balancing the usage counter (i.e., leaving it with a positive count). The core code would take care of setting the counter back to 0 before allowing another driver to bind to the interface. Later on when runtime PM was implemented for the entire kernel, the opposite decision was made: Drivers were required to balance their runtime-PM get and put calls. In order to maintain backward compatibility, however, the USB subsystem adapted to the new implementation by keeping an independent usage counter for each interface and using it to automatically adjust the normal usage counter back to 0 whenever a driver was unbound. This approach involves duplicating information, but what is worse, it doesn't work properly in cases where a USB class driver delays decrementing the usage counter until after the driver's disconnect() routine has returned and the counter has been adjusted back to 0. Doing so would cause the usage counter to become negative. There's even a warning about this in the USB power management documentation! As it happens, this is exactly what the hub driver does. The kick_hub_wq() routine increments the runtime-PM usage counter, and the corresponding decrement is carried out by hub_event() in the context of the hub_wq work-queue thread. This work routine may sometimes run after the driver has been unbound from its interface, and when it does it causes the usage counter to go negative. It is not possible for hub_disconnect() to wait for a pending hub_event() call to finish, because hub_disconnect() is called with the device lock held and hub_event() acquires that lock. The only feasible fix is to reverse the original design decision: remove the duplicate interface-specific usage counter and require USB drivers to balance their runtime PM gets and puts. As far as I know, all existing drivers currently do this.

2019-04-19coredump: fix race condition between mmget_not_zero()/get_task_mm() and core ↵Andrea Arcangeli
dumping The core dumping code has always run without holding the mmap_sem for writing, despite that is the only way to ensure that the entire vma layout will not change from under it. Only using some signal serialization on the processes belonging to the mm is not nearly enough. This was pointed out earlier. For example in Hugh's post from Jul 2017: https://lkml.kernel.org/r/alpine.LSU.2.11.1707191716030.2055@eggly.anvils "Not strictly relevant here, but a related note: I was very surprised to discover, only quite recently, how handle_mm_fault() may be called without down_read(mmap_sem) - when core dumping. That seems a misguided optimization to me, which would also be nice to correct" In particular because the growsdown and growsup can move the vm_start/vm_end the various loops the core dump does around the vma will not be consistent if page faults can happen concurrently. Pretty much all users calling mmget_not_zero()/get_task_mm() and then taking the mmap_sem had the potential to introduce unexpected side effects in the core dumping code. Adding mmap_sem for writing around the ->core_dump invocation is a viable long term fix, but it requires removing all copy user and page faults and to replace them with get_dump_page() for all binary formats which is not suitable as a short term fix. For the time being this solution manually covers the places that can confuse the core dump either by altering the vma layout or the vma flags while it runs. Once ->core_dump runs under mmap_sem for writing the function mmget_still_valid() can be dropped. Allowing mmap_sem protected sections to run in parallel with the coredump provides some minor parallelism advantage to the swapoff code (which seems to be safe enough by never mangling any vma field and can keep doing swapins in parallel to the core dumping) and to some other corner case. In order to facilitate the backporting I added "Fixes: 86039bd3b4e6" however the side effect of this same race condition in /proc/pid/mem should be reproducible since before 2.6.12-rc2 so I couldn't add any other "Fixes:" because there's no hash beyond the git genesis commit. Because find_extend_vma() is the only location outside of the process context that could modify the "mm" structures under mmap_sem for reading, by adding the mmget_still_valid() check to it, all other cases that take the mmap_sem for reading don't need the new check after mmget_not_zero()/get_task_mm(). The expand_stack() in page fault context also doesn't need the new check, because all tasks under core dumping are frozen.

2019-04-19USB: dummy-hcd: Fix failure to give back unlinked URBsAlan Stern
The syzkaller USB fuzzer identified a failure mode in which dummy-hcd would never give back an unlinked URB. This causes usb_kill_urb() to hang, leading to WARNINGs and unkillable threads. In dummy-hcd, all URBs are given back by the dummy_timer() routine as it scans through the list of pending URBS. Failure to give back URBs can be caused by failure to start or early exit from the scanning loop. The code currently has two such pathways: One is triggered when an unsupported bus transfer speed is encountered, and the other by exhausting the simulated bandwidth for USB transfers during a frame. This patch removes those two paths, thereby allowing all unlinked URBs to be given back in a timely manner. It adds a check for the bus speed when the gadget first starts running, so that dummy_timer() will never thereafter encounter an unsupported speed. And it prevents the loop from exiting as soon as the total bandwidth has been used up (the scanning loop continues, giving back unlinked URBs as they are found, but not transferring any more data). Thanks to Andrey Konovalov for manually running the syzkaller fuzzer to help track down the source of the bug.

2019-04-18clkdev: Hold clocks_mutex while iterating clocks listStephen Boyd
We recently introduced a change to support devm clk lookups. That change introduced a code-path that used clk_find() without holding the 'clocks_mutex'. Unfortunately, clk_find() iterates over the 'clocks' list and so we need to prevent the list from being modified at the same time. Do this by holding the mutex and checking to make sure it's held while iterating the list. Note, we don't really care if the lookup is freed after we find it with clk_find() because we're just doing a pointer comparison, but if we did care we would need to keep holding the mutex while we dereference the clk_lookup pointer.

Both Spectrum-1 and Spectrum-2 chips are currently configured such that pairs of TC n (which is used for UC traffic) and TC n+8 (which is used for MC traffic) are feeding into the same subgroup. Strict prioritization is configured between the two TCs, and by enabling MC-aware mode on the switch, the lower-numbered (UC) TCs are favored over the higher-numbered (MC) TCs. On Spectrum-2 however, there is an issue in configuration of the MC-aware mode. As a result, MC traffic is prioritized over UC traffic. To work around the issue, configure the MC TCs with DWRR mode (while keeping the UC TCs in strict mode). With this patch, the multicast-unicast arbitration results in the same behavior on both Spectrum-1 and Spectrum-2 chips.

2019-04-18device property: Add fwnode_graph_get_endpoint_by_id()Sakari Ailus
fwnode_graph_get_endpoint_by_id() is intended for obtaining local endpoints by a given local port. fwnode_graph_get_endpoint_by_id() is slightly different from its OF counterpart, of_graph_get_endpoint_by_regs(): instead of using -1 as a value to indicate that a port or an endpoint number does not matter, it uses flags to look for equal or greater endpoint. The port number is always fixed. It also returns only remote endpoints that belong to an available device, a behaviour that can be turned off with a flag.

2019-04-18drm/sun4i: Fix component unbinding and component master deletionPaul Kocialkowski
For our component-backed driver to be properly removed, we need to delete the component master in sun4i_drv_remove and make sure to call component_unbind_all in the master's unbind so that all components are unbound when the master is.

2019-04-18drm/sun4i: Set device driver data at bind time for use in unbindPaul Kocialkowski
Our sun4i_drv_unbind gets the drm device using dev_get_drvdata. However, that driver data is never set in sun4i_drv_bind. Set it there to avoid getting a NULL pointer at unbind time.

2019-04-18crypto: powerpc - convert to use crypto_simd_usable()Eric Biggers
Replace all calls to in_interrupt() in the PowerPC crypto code with !crypto_simd_usable(). This causes the crypto self-tests to test the no-SIMD code paths when CONFIG_CRYPTO_MANAGER_EXTRA_TESTS=y. The p8_ghash algorithm is currently failing and needs to be fixed, as it produces the wrong digest when no-SIMD updates are mixed with SIMD ones.

2019-04-18crypto: cavium - remove bogus code handling cryptdEric Biggers
The cavium crypto driver adds 'sizeof(struct ablkcipher_request)' to its request size because "the cryptd daemon uses this memory for request_ctx information". This is incorrect and unnecessary; cryptd doesn't require wrapped algorithms to reserve extra request space. So remove this. Also remove the unneeded memset() of the tfm context to 0. It's already zeroed on allocation. Signed-off-by: Eric Biggers <ebiggers@google.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

2019-04-18crypto: rsa - unimplement sign/verify for raw RSA backendsVitaly Chikunov
In preparation for new akcipher verify call remove sign/verify callbacks from RSA backends and make PKCS1 driver call encrypt/decrypt instead. This also complies with the well-known idea that raw RSA should never be used for sign/verify. It only should be used with proper padding scheme such as PKCS1 driver provides.
