2019-02-18r8169: remove unneeded mmiowb barriersHeiner Kallweit
writex() has implicit barriers, that's what makes it different from writex_relaxed(). Therefore these calls to mmiowb() can be removed. This patch was recently reverted due to a dependency with another problematic patch. But because it didn't contribute to the problem it was rebased and can be resubmitted.

2019-02-18r8152: Add support for MAC address pass through on RTL8153-BDDavid Chen
RTL8153-BD is used in Dell DA300 type-C dongle. It should be added to the whitelist of devices to activate MAC address pass through. Per confirming with Realtek all devices containing RTL8153-BD should activate MAC pass through and there won't use pass through bit on efuse like in RTL8153-AD.

2019-02-18net: dsa: Implement flow_dissect callback for tag_dsa.Rundong Ge
RPS not work for DSA devices since the 'skb_get_hash' will always get the invalid hash for dsa tagged packets. "[PATCH] tag_mtk: add flow_dissect callback to the ops struct" introduced the flow_dissect callback to get the right hash for MTK tagged packet. Tag_dsa and tag_edsa also need to implement the callback. Signed-off-by: Rundong Ge <rdong.ge@gmail.com> Reviewed-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: David S. Miller <davem@davemloft.net>

2019-02-19bpf/test_run: fix unkillable BPF_PROG_TEST_RUNStanislav Fomichev
Syzbot found out that running BPF_PROG_TEST_RUN with repeat=0xffffffff makes process unkillable. The problem is that when CONFIG_PREEMPT is enabled, we never see need_resched() return true. This is due to the fact that preempt_enable() (which we do in bpf_test_run_one on each iteration) now handles resched if it's needed. Let's disable preemption for the whole run, not per test. In this case we can properly see whether resched is needed. Let's also properly return -EINTR to the userspace in case of a signal interrupt. See recent discussion: http://lore.kernel.org/netdev/CAH3MdRWHr4N8jei8jxDppXjmw-Nw=puNDLbu1dQOFQHxfU2onA@mail.gmail.com I'll follow up with the same fix bpf_prog_test_run_flow_dissector in bpf-next.

2019-02-18net: crypto set sk to NULL when af_alg_release.Mao Wenan
KASAN has found use-after-free in sockfs_setattr. The existed commit 6d8c50dcb029 ("socket: close race condition between sock_close() and sockfs_setattr()") is to fix this simillar issue, but it seems to ignore that crypto module forgets to set the sk to NULL after af_alg_release.
