2a95183a5e ("netfilter: don't allocate space for arp/bridge .."): WARNING: CPU: 0 PID: 1 at net/netfilter/core.c:297 nf_hook_entry_head
by kernel test robot
Greetings,
0day kernel testing robot got the below dmesg and the first bad commit is
https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git master
commit 2a95183a5e0375df756efb2ca37602d71e8455f9
Author: Florian Westphal <fw(a)strlen.de>
AuthorDate: Thu Dec 7 16:28:26 2017 +0100

CommitDate: Mon Jan 8 18:01:11 2018 +0100
netfilter: don't allocate space for arp/bridge hooks unless needed
no need to define hook points if the family isn't supported.
Because we need these hooks for either nftables, arp/ebtables
or the 'call-iptables' hack we have in the bridge layer add two
new dependencies, NETFILTER_FAMILY_{ARP,BRIDGE}, and have the
users select them.

f3433c1010 ("x86/retpoline/entry: Convert entry assembler .."): BUG: unable to handle kernel paging request at fffffe0000007000
by kernel test robot
Greetings,
0day kernel testing robot got the below dmesg and the first bad commit is
git://git.infradead.org/users/dwmw2/random-2.6 retpoline
commit f3433c1010c6af61c9897f0f0447f81b991feac1
Author: David Woodhouse <dwmw(a)amazon.co.uk>
AuthorDate: Tue Jan 9 14:43:11 2018 +0000
Commit: Thomas Gleixner <tglx(a)linutronix.de>
CommitDate: Tue Jan 9 16:17:52 2018 +0100
x86/retpoline/entry: Convert entry assembler indirect jumps
Convert indirect jumps in core 32/64bit entry assembler code to use
non-speculative sequences when CONFIG_RETPOLINE is enabled.
Don't use CALL_NOSPEC in entry_SYSCALL_64_fastpath because the return
address after the 'call' instruction must be *precisely* at the
.Lentry_SYSCALL_64_after_fastpath label for stub_ptregs_64 to work,
and the use of alternatives will mess that up unless we play horrid
games to prepend with NOPs and make the variants the same length. It's
not worth it; in the case where we ALTERNATIVE out the retpoline, the
first instruction at __x86.indirect_thunk.rax is going to be a bare
jmp *%rax anyway.

[usb_add_gadget_udc_release] BUG: KASAN: double-free or invalid-free in (null)
by Fengguang Wu
Hello,
FYI this happens in mainline kernel 4.15.0-rc3.
It looks like a new regression.
It occurs in 23 out of 36 boots.

[lkp-robot] [sched/fair] a4c3c04974: unixbench.score -4.3% regression
by kernel test robot
Greeting,
FYI, we noticed a -4.3% regression of unixbench.score due to commit:
commit: a4c3c04974d648ee6e1a09ef4131eb32a02ab494 ("sched/fair: Update and fix the runnable propagation rule")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: unixbench
on test machine: 8 threads Ivy Bridge with 16G memory
with following parameters:
runtime: 300s
nr_task: 100%
test: shell1
cpufreq_governor: performance
test-description: UnixBench is the original BYTE UNIX benchmark suite aims to test performance of Unix-like system.
test-url: https://github.com/kdlucas/byte-unixbench
Details are as below:
-------------------------------------------------------------------------------------------------->
To reproduce:
git clone https://github.com/intel/lkp-tests.git
cd lkp-tests
bin/lkp install job.yaml # job file is attached in this email
bin/lkp run job.yaml
