2020-07-27arm64: dts: qcom: msm8992: Fix SDHCI1Konrad Dybcio
This commit ensures the correct IRQ type is set and disables the device by default. The mmc-hs400-1_8v property is also moved to Bullhead as it might not be present on all boards. The node has been renamed to sdhci@ instead of mmc@ and the phandle was changed to sdhc_1 to comply with the newer DTS style.

Add device tree support for the Sony Xperia Z5 smartphone. It's based on Sony Kitakami platform (msm8994) and hence a Kitakami-common DTSI has been created so as to reduce clutter when remaining devices are added.

2020-07-28xfrm: esp6: fix the location of the transport header with encapsulationSabrina Dubroca
commit 17175d1a27c6 ("xfrm: esp6: fix encapsulation header offset computation") changed esp6_input_done2 to correctly find the size of the IPv6 header that precedes the TCP/UDP encapsulation header, but didn't adjust the final call to skb_set_transport_header, which I assumed was correct in using skb_network_header_len. Xiumei Mu reported that when we create xfrm states that include port numbers in the selector, traffic from the user sockets is dropped. It turns out that we get a state mismatch in __xfrm_policy_check, because we end up trying to compare the encapsulation header's ports with the selector that's based on user traffic ports.

2020-07-27of: property: Add device link support for pinctrl-0 through pinctrl-8Saravana Kannan
Add support for pinctrl-0 through pinctrl-8 explicitly instead of trying to add support for pinctrl-%d properties. Of all the pinctrl-* properties in dts files (20322), only 47% (9531) are pinctrl-%d properties. Of all the pinctrl-%d properties, 99.5% (9486) are made up of pinctrl-[0-2]. 'pinctrl-8' is the current maximum found in dts files. Trying to parse all pinctrl-* properties and checking for pinctrl-%d is unnecessarily complicated. So, just add support for pinctrl-[0-8] for now. In the unlikely event we ever exceed pinctrl-8, we can come back and improve this.

A use-after-free in drm_gem_open_ioctl can happen if the GEM object handle is closed between the idr lookup and retrieving the size from said object since a local reference is not being held at that point. Hold the local reference while the object can still be accessed to fix this and plug the potential security hole.

When size_t maps to unsigned int (e.g. on 32-bit powerpc), then the comparison with 1<<35 is always true. Clang 9 threw: warning: result of comparison of constant 34359738368 with \ expression of type 'size_t' (aka 'unsigned int') is always true \ [-Wtautological-constant-out-of-range-compare] while (total < FILE_SZ) { Tested: make -C tools/testing/selftests TARGETS="net" run_tests Fixes: 192dc405f308 ("selftests: net: add tcp_mmap program") Signed-off-by: Tanner Love <tannerlove@google.com> Acked-by: Willem de Bruijn <willemb@google.com> Reviewed-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S.
