The imx8 config keeps causing issues: WARNING: unmet direct dependencies detected for SND_SOC_SOF_IMX8M Depends on [n]: SOUND [=y] && !UML && SND [=y] && SND_SOC [=m] && SND_SOC_SOF_TOPLEVEL [=y] && SND_SOC_SOF_IMX_TOPLEVEL [=y] && IMX_DSP [=n] Selected by [m]: - SND_SOC_SOF_IMX_OF [=m] && SOUND [=y] && !UML && SND [=y] && SND_SOC [=m] && SND_SOC_SOF_TOPLEVEL [=y] && SND_SOC_SOF_IMX_TOPLEVEL [=y] && SND_SOC_SOF_IMX8M_SUPPORT [=y] This is complicated by two drivers having dependencies on both platform specific drivers and the SND_SOC_SOF_OF framework code, and using an somewhat obscure method to build them the same way as the SOC_SOF_OF symbol (built-in or modular). My solution now ensures that the two drivers can only be enabled when the dependencies are met: - When the platform specific drivers are built-in, everything is fine, as SOC_SOF_OF is either =y or =m - When both are loadable modules, it also works, both for Kconfig and at runtime - When the hardware drivers are loadable modules or disabled, and SOC_SOF_OF=y, prevent the IMX_SOF_OF drivers from being turned on, as this would be broken. It seems that this is just an elaborate way to describe two tristate symbols that have straight dependencies, but maybe I'm missing some subtle point. It seems to always build for me now.

playback on sdw platforms Now the trigger sequence is set to SND_SOC_DPCM_TRIGGER_POST for SOF. This means FE will be stopped before BE, so BE will consume invalid data and this generates huge pop noise.

2020-04-30powerpc/uaccess: Evaluate macro arguments once, before user access is allowedNicholas Piggin
get/put_user() can be called with nontrivial arguments. fs/proc/page.c has a good example: if (put_user(stable_page_flags(ppage), out)) { stable_page_flags() is quite a lot of code, including spin locks in the page allocator. Ensure these arguments are evaluated before user access is allowed. This improves security by reducing code with access to userspace, but it also fixes a PREEMPT bug with KUAP on powerpc/64s: stable_page_flags() is currently called with AMR set to allow writes, it ends up calling spin_unlock(), which can call preempt_schedule. But the task switch code can not be called with AMR set (it relies on interrupts saving the register), so this blows up. It's fine if the code inside allow_user_access() is preemptible, because a timer or IPI will save the AMR, but it's not okay to explicitly cause a reschedule.

2020-04-30ovl: clear ATTR_OPEN from attr->ia_validVivek Goyal
As of now during open(), we don't pass bunch of flags to underlying filesystem. O_TRUNC is one of these. Normally this is not a problem as VFS calls ->setattr() with zero size and underlying filesystem sets file size to 0. But when overlayfs is running on top of virtiofs, it has an optimization where it does not send setattr request to server if dectects that truncation is part of open(O_TRUNC). It assumes that server already zeroed file size as part of open(O_TRUNC). fuse_do_setattr() { if (attr->ia_valid & ATTR_OPEN) { /* * No need to send request to userspace, since actual * truncation has already been done by OPEN. But still * need to truncate page cache. */ } } IOW, fuse expects O_TRUNC to be passed to it as part of open flags. But currently overlayfs does not pass O_TRUNC to underlying filesystem hence fuse/virtiofs breaks. Setup overlayfs on top of virtiofs and following does not zero the file size of a file is either upper only or has already been copied up. fd = open(foo.txt, O_TRUNC | O_WRONLY); There are two ways to fix this. Either pass O_TRUNC to underlying filesystem or clear ATTR_OPEN from attr->ia_valid so that fuse ends up sending a SETATTR request to server. Miklos is concerned that O_TRUNC might have side affects so it is better to clear ATTR_OPEN for now. Hence this patch clears ATTR_OPEN from attr->ia_valid. I found this problem while running unionmount-testsuite. With this patch, unionmount-testsuite passes with overlayfs on top of virtiofs.

2020-04-30ovl: clear ATTR_FILE from attr->ia_validVivek Goyal
ovl_setattr() can be passed an attr which has ATTR_FILE set and attr->ia_file is a file pointer to overlay file. This is done in open(O_TRUNC) path. We should either replace with attr->ia_file with underlying file object or clear ATTR_FILE so that underlying filesystem does not end up using overlayfs file object pointer. There are no good use cases yet so for now clear ATTR_FILE. fuse seems to be one user which can use this. But it can work even without this. So it is not mandatory to pass ATTR_FILE to fuse.

2020-04-30crypto: arch/lib - limit simd usage to 4k chunksJason A. Donenfeld
The initial Zinc patchset, after some mailing list discussion, contained code to ensure that kernel_fpu_enable would not be kept on for more than a 4k chunk, since it disables preemption. The choice of 4k isn't totally scientific, but it's not a bad guess either, and it's what's used in both the x86 poly1305, blake2s, and nhpoly1305 code already (in the form of PAGE_SIZE, which this commit corrects to be explicitly 4k for the former two). Ard did some back of the envelope calculations and found that at 5 cycles/byte (overestimate) on a 1ghz processor (pretty slow), 4k means we have a maximum preemption disabling of 20us, which Sebastian confirmed was probably a good limit. Unfortunately the chunking appears to have been left out of the final patchset that added the glue code. So, this commit adds it back in.

2020-04-29wireguard: receive: use tunnel helpers for decapsulating ECN markingsToke Høiland-Jørgensen
WireGuard currently only propagates ECN markings on tunnel decap according to the old RFC3168 specification. However, the spec has since been updated in RFC6040 to recommend slightly different decapsulation semantics. This was implemented in the kernel as a set of common helpers for ECN decapsulation, so let's just switch over WireGuard to using those, so it can benefit from this enhancement and any future tweaks. We do not drop packets with invalid ECN marking combinations, because WireGuard is frequently used to work around broken ISPs, which could be doing that.

2020-04-29mptcp: replace mptcp_disconnect with a stubFlorian Westphal
Paolo points out that mptcp_disconnect is bogus: "lock_sock(sk); looks suspicious (lock should be already held by the caller) And call to: tcp_disconnect(sk, flags); too, sk is not a tcp socket". ->disconnect() gets called from e.g. inet_stream_connect when one tries to disassociate a connected socket again (to re-connect without closing the socket first). MPTCP however uses mptcp_stream_connect, not inet_stream_connect, for the mptcp-socket connect call. inet_stream_connect only gets called indirectly, for the tcp socket, so any ->disconnect() calls end up calling tcp_disconnect for that tcp subflow sk. This also explains why syzkaller has not yet reported a problem here. So for now replace this with a stub that doesn't do anything.
