2020-10-30wireguard: selftests: check that route_me_harder packets use the right skJason A. Donenfeld
If netfilter changes the packet mark, the packet is rerouted. The ip_route_me_harder family of functions fails to use the right sk, opting to instead use skb->sk, resulting in a routing loop when used with tunnels. With the next change fixing this issue in netfilter, test for the relevant condition inside our test suite, since wireguard was where the bug was discovered.

2020-10-27selftests/ftrace: Use $FUNCTION_FORK to reference kernel fork functionSteven Rostedt (VMware)
Commit cad6967ac108 ("fork: introduce kernel_clone()") replaced "_do_fork()" with "kernel_clone()". The ftrace selftests reference the fork function in several of the tests. The rename will make the tests break, but if those names are changed in the tests, they would then break on older kernels. The same set of tests should pass older kernels if they have previously passed. Obviously, a new test may not work on older kernels if the test was added due to a bug or a new feature. The setup of ftracetest will now create a $FUNCTION_FORK bash variable that will contain "_do_fork" for older kernels and "kernel_clone" for newer ones. It figures out the proper name by examining /proc/kallsyms. Note, available_filter_functions could also be used, but because some tests should be able to pass without function tracing enabled, it could not be used.

2020-10-26cpupower: Provide online and offline CPU informationBrahadambal Srinivasan
When a user tries to modify cpuidle or cpufreq properties on offline CPUs, the tool returns success (exit status 0) but also does not provide any warning message regarding offline cpus that may have been specified but left unchanged. In case of all or a few CPUs being offline, it can be difficult to keep track of which CPUs didn't get the new frequency or idle state set. Silent failures are difficult to keep track of when there are a huge number of CPUs on which the action is performed. This patch adds helper functions to find both online and offline CPUs and print them out accordingly. We use these helper functions in cpuidle-set and cpufreq-set to print an additional message if the user attempts to modify offline cpus. Reported-by: Pavithra R.

2020-10-26staging: ion: remove from the treeGreg Kroah-Hartman
The ION android code has long been marked to be removed, now that we dma-buf support merged into the real part of the kernel. It was thought that we could wait to remove the ion kernel at a later time, but as the out-of-tree Android fork of the ion code has diverged quite a bit, and any Android device using the ion interface uses that forked version and not this in-tree version, the in-tree copy of the code is abandonded and not used by anyone. Combine this abandoned codebase with the need to make changes to it in order to keep the kernel building properly, which then causes merge issues when merging those changes into the out-of-tree Android code, and you end up with two different groups of people (the in-kernel-tree developers, and the Android kernel developers) who are both annoyed at the current situation. Because of this problem, just drop the in-kernel copy of the ion code now, as it's not used, and is only causing problems for everyone involved.

2020-10-25treewide: Convert macro and uses of __section(foo) to __section("foo")Joe Perches
Use a more generic form for __section that requires quotes to avoid complications with clang and gcc differences. Remove the quote operator # from compiler_attributes.h __section macro. Convert all unquoted __section(foo) uses to quoted __section("foo"). Also convert __attribute__((section("foo"))) uses to __section("foo") even if the __attribute__ has multiple list entry forms. Conversion done using the script at: https://lore.kernel.org/lkml/75393e5ddc272dc7403de74d645e6c6e0f4e70eb.camel@perches.com/2-convert_section.pl Signed-off-by: Joe Perches <joe@perches.com> Reviewed-by: Nick Desaulniers <ndesaulniers@gooogle.com> Reviewed-by: Miguel Ojeda <ojeda@kernel.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
