2020-01-16netfilter: nat: fix ICMP header corruption on ICMP errorsEyal Birger
Commit 8303b7e8f018 ("netfilter: nat: fix spurious connection timeouts") made nf_nat_icmp_reply_translation() use icmp_manip_pkt() as the l4 manipulation function for the outer packet on ICMP errors. However, icmp_manip_pkt() assumes the packet has an 'id' field which is not correct for all types of ICMP messages. This is not correct for ICMP error packets, and leads to bogus bytes being written the ICMP header, which can be wrongfully regarded as 'length' bytes by RFC 4884 compliant receivers. Fix by assigning the 'id' field only for ICMP messages that have this semantic.

This patch fixes a WARN_ON in nft_set_destroy() due to missing set reference count drop from the preparation phase. This is triggered by the module autoload path. Do not exercise the abort path from nft_request_module() while preparation phase cleaning up is still pending.

2020-01-16Merge tag 'asoc-fix-v5.5-rc6' of ↵Takashi Iwai
https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus ASoC: Fixes for v5.5 This is mostly driver specific fixes, plus an error handling fix in the core. There is a rather large diffstat for the stm32 SAI driver, this is a very large but mostly mechanical update which wraps every register access in the driver to allow a fix to the locking which avoids circular locks, the active change is much smaller and more reasonably sized.

2020-01-16drm/i915/execlists: Leave resetting ring to intel_ringChris Wilson
We need to allow concurrent intel_context_unpin, which means avoiding doing destructive operations like intel_ring_reset(). This was already fixed for intel_ring_unpin() in commit 0725d9a31869 ("drm/i915/gt: Make intel_ring_unpin() safe for concurrent pint"), but I overlooked that execlists_context_unpin() also made the same mistake.

2020-01-16fuse: fix fuse_send_readpages() in the syncronous read caseMiklos Szeredi
Buffered read in fuse normally goes via: -> generic_file_buffered_read() -> fuse_readpages() -> fuse_send_readpages() ->fuse_simple_request() [called since v5.4] In the case of a read request, fuse_simple_request() will return a non-negative bytecount on success or a negative error value. A positive bytecount was taken to be an error and the PG_error flag set on the page. This resulted in generic_file_buffered_read() falling back to ->readpage(), which would repeat the read request and succeed. Because of the repeated read succeeding the bug was not detected with regression tests or other use cases. The FTP module in GVFS however fails the second read due to the non-seekable nature of FTP downloads. Fix by checking and ignoring positive return value from fuse_simple_request().

2020-01-16mm, drm/ttm: Fix vm page protection handlingThomas Hellstrom
TTM graphics buffer objects may, transparently to user-space, move between IO and system memory. When that happens, all PTEs pointing to the old location are zapped before the move and then faulted in again if needed. When that happens, the page protection caching mode- and encryption bits may change and be different from those of struct vm_area_struct::vm_page_prot. We were using an ugly hack to set the page protection correctly. Fix that and instead export and use vmf_insert_mixed_prot() or use vmf_insert_pfn_prot(). Also get the default page protection from struct vm_area_struct::vm_page_prot rather than using vm_get_page_prot(). This way we catch modifications done by the vm system for drivers that want write-notification.
