BPF programs can be used to determine the message boundaries. From Tom Herbert. 6) Add 802.1AE MACSEC support, from Sabrina Dubroca. 7) Avoid factorial complexity when taking down an inetdev interface with lots of configured addresses. We were doing things like traversing the entire address less for each address removed, and flushing the entire netfilter conntrack table for every address as well. 8) Add and use SKB bulk free infrastructure, from Jesper Brouer. 9) Allow offloading u32 classifiers to hardware, and implement for ixgbe, from John Fastabend. 10) Allow configuring IRQ coalescing parameters on a per-queue basis, from Kan Liang. 11) Extend ethtool so that larger link mode masks can be supported.

2016-03-02selftests/powerpc: Remove -flto from common CFLAGSSuraj Jitindar Singh1-1/+1
LTO can cause GCC to inline some functions which have attributes set. The act of inlining the functions can lead to GCC forgetting about the attributes which leads to incorrect tests. Notable example being: __attribute__((__target__("no-vsx"))) LTO can also interact strangely with custom assembly functions and cause tests to intermittently fail. Both these cases are hard to detect and require manual inspection of binaries which is unlikely to happen for all tests. Furthermore, LTO optimisations are not necessary for selftests and correctness is paramount and as such it is best to disable LTO. LTO can be enabled on a per test basis. A pseries_le_defconfig kernel on a POWER8 was used to determine that the same subset of selftests pass and fail with and without -flto in the common Makefile.

As the stack tracer scans the entire kernel stack, KASAN triggers seeing it as a "stack out of bounds" error. As the scan is looking at the contents of the stack from parent functions.

The ftracetest instance test used parsing of the "jobs" output to find the pid of the subshell that is executed previously. But this is not portable to all major shells that may run these tests. The proper way to get the pid of the subshell is the shell command "$!". This will return the pid of the previously executed command. Use that instead, otherwise the test does not work in all environments.

This catches a regression from the compat syscall rework. The 32-bit variant of this test currently fails. The issue is that, for a 32-bit tracer and a 32-bit tracee, GETREGS+SETREGS with no changes should be a no-op. It currently isn't a no-op if RAX indicates signal restart, because the high bits get cleared and the kernel loses track of the restart state.

2016-02-17x86/signal/64: Re-add support for SS in the 64-bit signal contextAndy Lutomirski1-3/+2
This is a second attempt to make the improvements from c6f2062935c8 ("x86/signal/64: Fix SS handling for signals delivered to 64-bit programs"), which was reverted by 51adbfbba5c6 ("x86/signal/64: Add support for SS in the 64-bit signal context"). This adds two new uc_flags flags. UC_SIGCONTEXT_SS will be set for all 64-bit signals (including x32). It indicates that the saved SS field is valid and that the kernel supports the new behavior. The goal is to fix a problems with signal handling in 64-bit tasks: SS wasn't saved in the 64-bit signal context, making it awkward to determine what SS was at the time of signal delivery and making it impossible to return to a non-flat SS (as calling sigreturn clobbers SS). This also made it extremely difficult for 64-bit tasks to return to fully-defined 16-bit contexts, because only the kernel can easily do espfix64, but sigreturn was unable to set a non-flag SS:ESP. (DOSEMU has a monstrous hack to partially work around this limitation.) If we could go back in time, the correct fix would be to make 64-bit signals work just like 32-bit signals with respect to SS: save it in signal context, reset it when delivering a signal, and restore it in sigreturn. Unfortunately, doing that (as I tried originally) breaks DOSEMU: DOSEMU wouldn't reset the signal context's SS when clearing the LDT and changing the saved CS to 64-bit mode, since it predates the SS context field existing in the first place. This patch is a bit more complicated, and it tries to balance a bunch of goals. It makes most cases of changing ucontext->ss during signal handling work as expected. I do this by special-casing the interesting case. On sigreturn, ucontext->ss will be honored by default, unless the ucontext was created from scratch by an old program and had a 64-bit CS (unfortunately, CRIU can do this) or was the result of changing a 32-bit signal context to 64-bit without resetting SS (as DOSEMU does). For the benefit of new 64-bit software that uses segmentation (new versions of DOSEMU might), the new behavior can be detected with a new ucontext flag UC_SIGCONTEXT_SS. To avoid compilation issues, __pad0 is left as an alias for ss in ucontext. The nitty-gritty details are documented in the header file. This patch also re-enables the sigreturn_64 and ldt_gdt_64 selftests, as the kernel change allows both of them to pass.

2016-02-11soreuseport: BPF selection functional test for TCPCraig Gallek4-8/+370
Unfortunately the existing test relied on packet payload in order to map incoming packets to sockets. In order to get this to work with TCP, TCP_FASTOPEN needed to be used. Since the fast open path is slightly different than the standard TCP path, I created a second test which sends to reuseport group members based on receiving cpu core id. This will probably serve as a better real-world example use as well. Signed-off-by: Craig Gallek <kraig@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2016-02-10efi: Make efivarfs entries immutable by defaultPeter Jones2-4/+87
"rm -rf" is bricking some peoples' laptops because of variables being used to store non-reinitializable firmware driver data that's required to POST the hardware. These are 100% bugs, and they need to be fixed, but in the mean time it shouldn't be easy to *accidentally* brick machines. We have to have delete working, and picking which variables do and don't work for deletion is quite intractable, so instead make everything immutable by default (except for a whitelist), and make tools that aren't quite so broad-spectrum unset the immutable flag.
