2019-11-22drm/amdgpu: invalidate mmhub semaphore workaround in gmc9/gmc10changzhu
It may lose gpuvm invalidate acknowldege state across power-gating off cycle. To avoid this issue in gmc9/gmc10 invalidation, add semaphore acquire before invalidation and semaphore release after invalidation. After adding semaphore acquire before invalidation, the semaphore register become read-only if another process try to acquire semaphore. Then it will not be able to release this semaphore. Then it may cause deadlock problem. If this deadlock problem happens, it needs a semaphore firmware fix.

2019-11-22Revert "drm/i915/gt: Wait for new requests in intel_gt_retire_requests()"Chris Wilson
From inside an active timeline in the execbuf ioctl, we may try to reclaim some space in the GGTT. We need GGTT space for all objects on !full-ppgtt platforms, and for context images everywhere. However, to free up space in the GGTT we may need to remove some pinned objects (e.g. context images) that require flushing the idle barriers to remove. For this we use the big hammer of intel_gt_wait_for_idle() However, commit 7936a22dd466 ("drm/i915/gt: Wait for new requests in intel_gt_retire_requests()") will continue spinning on the wait if a timeline is active but lacks requests, as is the case during execbuf reservation. Spinning forever is quite time consuming, so revert that commit and start again. In practice, the effect commit 7936a22dd466 was trying to achieve is accomplished by commit 1683d24c1470 ("drm/i915/gt: Move new timelines to the end of active_list"), so there is no immediate rush to replace the looping.

2019-11-22virt_wifi: fix use-after-free in virt_wifi_newlink()Taehee Yoo
When virt_wifi interface is created, virt_wifi_newlink() is called and it calls register_netdevice(). if register_netdevice() fails, it internally would call ->priv_destructor(), which is virt_wifi_net_device_destructor() and it frees netdev. but virt_wifi_newlink() still use netdev. So, use-after-free would occur in virt_wifi_newlink(). Test commands: ip link add dummy0 type dummy modprobe bonding ip link add bonding_masters link dummy0 type virt_wifi Splat looks like: [ 202.220554] BUG: KASAN: use-after-free in virt_wifi_newlink+0x88b/0x9a0 [virt_wifi] [ 202.221659] Read of size 8 at addr ffff888061629cb8 by task ip/852 [ 202.222896] CPU: 1 PID: 852 Comm: ip Not tainted 5.4.0-rc5 #3 [ 202.223765] Hardware name: innotek GmbH VirtualBox/VirtualBox, BIOS VirtualBox 12/01/2006 [ 202.225073] Call Trace: [ 202.225532] dump_stack+0x7c/0xbb [ 202.226869] print_address_description.constprop.5+0x1be/0x360 [ 202.229362] __kasan_report+0x12a/0x16f [ 202.230714] kasan_report+0xe/0x20 [ 202.232595] virt_wifi_newlink+0x88b/0x9a0 [virt_wifi] [ 202.233370] __rtnl_newlink+0xb9f/0x11b0 [ 202.244909] rtnl_newlink+0x65/0x90 [ ... ] Cc: stable@vger.kernel.org Fixes: c7cdba31ed8b ("mac80211-next: rtnetlink wifi simulation device") Signed-off-by: Taehee Yoo <ap420073@gmail.com> Link: https://lore.kernel.org/r/20191121122645.9355-1-ap420073@gmail.com [trim stack dump a bit] Signed-off-by: Johannes Berg <johannes.berg@intel.com>

2019-11-22crypto: vmx - Avoid weird build failuresMichael Ellerman
In the vmx crypto Makefile we assign to a variable called TARGET and pass that to the aesp8-ppc.pl and ghashp8-ppc.pl scripts. The variable is meant to describe what flavour of powerpc we're building for, eg. either 32 or 64-bit, and big or little endian. Unfortunately TARGET is a fairly common name for a make variable, and if it happens that TARGET is specified as a command line parameter to make, the value specified on the command line will override our value. In particular this can happen if the kernel Makefile is driven by an external Makefile that uses TARGET for something. This leads to weird build failures, eg: nonsense at /build/linux/drivers/crypto/vmx/ghashp8-ppc.pl line 45. /linux/drivers/crypto/vmx/Makefile:20: recipe for target 'drivers/crypto/vmx/ghashp8-ppc.S' failed Which shows that we passed an empty value for $(TARGET) to the perl script, confirmed with make V=1: perl /linux/drivers/crypto/vmx/ghashp8-ppc.pl > drivers/crypto/vmx/ghashp8-ppc.S We can avoid this confusion by using override, to tell make that we don't want anything to override our variable, even a value specified on the command line. We can also use a less common name, given the script calls it "flavour", let's use that. Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
