[ Upstream commit 242d3a49 ] For each netns (except init_net), we initialize its null entry in 3 places: 1) The template itself, as we use kmemdup() 2) Code around dst_init_metrics() in ip6_route_net_init() 3) ip6_route_dev_notify(), which is supposed to initialize it after loopback registers Unfortunately the last one still happens in a wrong order because we expect to initialize net->ipv6.ip6_null_entry->rt6i_idev to net->loopback_dev's idev, thus we have to do that after we add idev to loopback. However, this notifier has priority == 0 same as ipv6_dev_notf, and ipv6_dev_notf is registered after ip6_route_dev_notifier so it is called actually after ip6_route_dev_notifier. This is similar to commit 2f460933 ("ipv6: initialize route null entry in addrconf_init()") which fixes init_net. Fix it by picking a smaller priority for ip6_route_dev_notifier. Also, we have to release the refcnt accordingly when unregistering loopback_dev because device exit functions are called before subsys exit functions. Acked-by:

[ Upstream commit 2f460933 ] Andrey reported a crash on init_net.ipv6.ip6_null_entry->rt6i_idev since it is always NULL. This is clearly wrong, we have code to initialize it to loopback_dev, unfortunately the order is still not correct. loopback_dev is registered very early during boot, we lose a chance to re-initialize it in notifier. addrconf_init() is called after ip6_route_init(), which means we have no chance to correct it. Fix it by moving this initialization explicitly after ipv6_add_dev(init_net.loopback_dev) in addrconf_init(). Reported-by:

[ Upstream commit 77ef033b ] IFLA_PHYS_PORT_NAME is a string attribute, so terminate it with \0. Otherwise libnl3 fails to validate netlink messages with this attribute. "ip -detail a" assumes too that the attribute is NUL-terminated when printing it. It often was, due to padding. I noticed this as libvirtd failing to start on a system with sfc driver after upgrading it to Linux 4.11, i.e. when sfc added support for phys_port_name. Signed-off-by:

[ Upstream commit 7162fb24 ] Andrey found a way to trigger the WARN_ON_ONCE(delta < len) in skb_try_coalesce() using syzkaller and a filter attached to a TCP socket over loopback interface. I believe one issue with looped skbs is that tcp_trim_head() can end up producing skb with under estimated truesize. It hardly matters for normal conditions, since packets sent over loopback are never truncated. Bytes trimmed from skb->head should not change skb truesize, since skb->head is not reallocated.

[ Upstream commit ab949d51 ] Imre Deak reported a deadlock of HD-audio driver at unbinding while it's still in probing. Since we probe the codecs asynchronously in a work, the codec driver probe may still be kicked off while the controller itself is being unbound. And, azx_remove() tries to process all pending tasks via cancel_work_sync() for fixing the other races (see commit [0b8c8219: ALSA: hda - Cancel probe work instead of flush at remove]), now we may meet a bizarre deadlock: Unbind snd_hda_intel via sysfs: device_release_driver() -> device_lock(snd_hda_intel) -> azx_remove() -> cancel_work_sync(azx_probe_work) azx_probe_work(): codec driver probe() -> __driver_attach() -> device_lock(snd_hda_intel) This deadlock is caused by the fact that both device_release_driver() and driver_probe_device() take both the device and its parent locks at the same time. The codec device sets the controller device as its parent, and this lock is taken before the probe() callback is called, while the controller remove() callback gets called also with the same lock. In this patch, as an ugly workaround, we unlock the controller device temporarily during cancel_work_sync() call. The race against another bind call should be still suppressed by the parent's device lock. Reported-by:

[ Upstream commit 6183468a ] Similar to commit fcd2042e ("mwifiex: printk() overflow with 32-byte SSIDs"), we failed to account for the existence of 32-char SSIDs in our debugfs code. Unlike in that case though, we zeroed out the containing struct first, and I'm pretty sure we're guaranteed to have some padding after the 'ssid.ssid' and 'ssid.ssid_len' fields (the struct is 33 bytes long). So, this is the difference between: # cat /sys/kernel/debug/mwifiex/mlan0/info ... essid="0123456789abcdef0123456789abcdef " ... and the correct output: # cat /sys/kernel/debug/mwifiex/mlan0/info ... essid="0123456789abcdef0123456789abcdef" ...

[ Upstream commit d62acc5e ] The device specific data is not fully initialized on request_threaded_irq(). This may cause a crash when the IRQ handler tries to reference them. Fix the issue by installing IRQ handler at the end of the probe. Fixes: d7bf353f ("bq24190_charger: Add support for TI BQ24190 Battery Charger") Signed-off-by:

[ Upstream commit e05ad7e0 ] pm_resume() does a register_reset() which clears charger host mode. Fix by calling set_mode_host() after the reset. Fixes: d7bf353f ("bq24190_charger: Add support for TI BQ24190 Battery Charger") Signed-off-by:

[ Upstream commit 767eee36 ] The interrupt signal is TRIGGER_FALLING. This is is specified in the data sheet PIN FUNCTIONS: "The INT pin sends active low, 256us pulse to host to report charger device status and fault." Also the direction can be seen in the data sheet Figure 37 "BQ24190 with D+/D- Detection and USB On-The-Go (OTG)" which shows a 10k pull-up resistor installed for the sample configurations.

[ Upstream commit a7e0fb6c ] Currently the opal_exit tracepoint usually shows the opcode as 0: <idle>-0 [047] d.h. 635.654292: opal_entry: opcode=63 <idle>-0 [047] d.h. 635.654296: opal_exit: opcode=0 retval=0 kopald-1209 [019] d... 636.420943: opal_entry: opcode=10 kopald-1209 [019] d... 636.420959: opal_exit: opcode=0 retval=0 This is because we incorrectly load the opcode into r0 before calling __trace_opal_exit(), whereas it expects the opcode in r3 (first function parameter). In fact we are leaving the retval in r3, so opcode and retval will always show the same value. Instead load the opcode into r3, resulting in: <idle>-0 [040] d.h. 636.618625: opal_entry: opcode=63 <idle>-0 [040] d.h. 636.618627: opal_exit: opcode=63 retval=0 Fixes: c49f6353 ("powernv: Add OPAL tracepoints") Signed-off-by:

[ Upstream commit 4cca0457 ] The switch that conditionally sets CPUPOWER_CAP_HAS_TURBO_RATIO and CPUPOWER_CAP_IS_SNB flags is missing a break, so all cores get both flags set and an assumed base clock of 100 MHz for turbo values. Reported-by:
