Action init API was changed to always take reference to action, even when
overwriting existing action. Substitute conditional action release, which
was executed only if action is newly created, with unconditional release in
tcf_ife_init() error handling code to prevent double free or memory leak in
case of overwrite.
Fixes: 4e8ddd7f1758 ("net: sched: don't release reference on action overwrite")

Prepare input updates for 4.19 merge window.

The allocated size can be (at least?) as large as megabytes, and
there's no need for it to be physically contiguous.
May avoid spurious failures to initialize / suspend the corresponding
block while there's memory pressure.

This patch fixes a warning reported by the kbuild test robot (from linux-next
tree):
net/netfilter/nft_tproxy.c: In function 'nft_tproxy_eval_v6':
>> net/netfilter/nft_tproxy.c:85:9: warning: missing braces around initializer [-Wmissing-braces]
struct in6_addr taddr = {0};
^
net/netfilter/nft_tproxy.c:85:9: warning: (near initialization for 'taddr.in6_u') [-Wmissing-braces]
This warning is actually caused by a gcc bug already resolved in newer
versions (kbuild used 4.9) so this kind of initialization is omitted and
memset is used instead.

Recently, transparent proxy support has been added to nf_tables so that
this document should be updated with the new information.
- Nft commands are added as alternatives to iptables ones.
- The link for a patched iptables is removed as it is already part of
the mainline iptables implementation (and the link is dead).
- tcprdr is added as an example implementation of a transparent proxy

eacd86ca3b03 ("net/netfilter/x_tables.c: use kvmalloc()
in xt_alloc_table_info()") has unintentionally fortified
xt_alloc_table_info allocation when __GFP_RETRY has been dropped from
the vmalloc fallback. Later on there was a syzbot report that this
can lead to OOM killer invocations when tables are too large and
0537250fdc6c ("netfilter: x_tables: make allocation less aggressive")
has been merged to restore the original behavior. Georgi Nikolov however
noticed that he is not able to install his iptables anymore so this can
be seen as a regression.
The primary argument for 0537250fdc6c was that this allocation path
shouldn't really trigger the OOM killer and kill innocent tasks. On the
other hand the interface requires root and as such should allow what the
admin asks for. Root inside a namespaces makes this more complicated
because those might be not trusted in general. If they are not then such
namespaces should be restricted anyway. Therefore drop the __GFP_NORETRY
and replace it by __GFP_ACCOUNT to enfore memcg constrains on it.

netns exit
When a netnsamespace exits, the nf_tables pernet_ops will remove all rules.
However, there is one caveat:
Base chains that register ingress hooks will cause use-after-free:
device is already gone at that point.
The device event handlers prevent this from happening:
netns exit synthesizes unregister events for all devices.
However, an improper fix for a race condition made the notifiers a no-op
in case they get called from netns exit path, so revert that part.
This is safe now as the previous patch fixed nf_tables pernet ops
and device notifier initialisation ordering.

Shaochun Chen points out we leak dumper filter state allocations
stored in dump_control->data in case there is an error before netlink sets
cb_running (after which ->done will be called at some point).
In order to fix this, add .start functions and move allocations there.
Same pattern as used in commit 90fd131afc565159c9e0ea742f082b337e10f8c6
("netfilter: nf_tables: move dumper state allocation into ->start").

In order to determine allocation size of set, ->privsize is invoked.
At this point, both desc->size and size of each data structure of set
are used. desc->size means number of element that is given by user.
desc->size is u32 type. so that upperlimit of set element is 4294967295.
but return type of ->privsize is also u32. hence overflow can occurred.
test commands:
%nft add table ip filter
%nft add set ip filter hash1 { type ipv4_addr \; size 4294967295 \; }
%nft list ruleset

Since commit 500462a9de65 ("timers: Switch to a non-cascading wheel"),
timers duration can last even 12.5% more than the scheduled interval.
IPVS has two handlers, /proc/net/ip_vs_conn and /proc/net/ip_vs_conn_sync,
which shows the remaining time before that a connection expires.
The default expire time for a connection is 60 seconds, and the
expiration timer can fire even 4 seconds later than the scheduled time.
The expiration time is calculated subtracting jiffies to the scheduled
expiration time, and it's shown as a huge number when the timer fires late,

We came across infinite loop in ipvs when using ipvs in docker
env.
When ipvs receives new packets and cannot find an ipvs connection,
it will create a new connection, then if the dest is unavailable
(i.e. IP_VS_DEST_F_AVAILABLE), the packet will be dropped sliently.
But if the dropped packet is the first packet of this connection,
the connection control timer never has a chance to start and the
ipvs connection cannot be released. This will lead to memory leak, or
infinite loop in cleanup_net() when net namespace is released like
this:
ip_vs_conn_net_cleanup at ffffffffa0a9f31a [ip_vs]
__ip_vs_cleanup at ffffffffa0a9f60a [ip_vs]
ops_exit_list at ffffffff81567a49
cleanup_net at ffffffff81568b40
process_one_work at ffffffff810a851b
worker_thread at ffffffff810a9356
kthread at ffffffff810b0b6f
ret_from_fork at ffffffff81697a18
race condition:
CPU1 CPU2
ip_vs_in()
ip_vs_conn_new()
ip_vs_del_dest()
__ip_vs_unlink_dest()
~IP_VS_DEST_F_AVAILABLE
cp->dest && !IP_VS_DEST_F_AVAILABLE
__ip_vs_conn_put
...
cleanup_net ---> infinite looping
Fix this by checking whether the timer already started.

Pull clk updates from Stephen Boyd:
"The new and exciting feature this time around is in the clk core.
We've added duty cycle support to the clk API so that clk signal duty
cycle ratios can be adjusted while taking into account things like clk
dividers and clk tree hierarchy. So far only one SoC has implemented
support for this, but I expect there will be more to come in the
future.
Outside of the core, we have the usual pile of clk driver updates and
additions. The Amlogic meson driver got the most lines in the diffstat
this time around because it added support for a whole bunch of
hardware and duty cycle configuration. After that the Rockchip PX30,
Qualcomm SDM845, and Renesas SoC drivers fill in a majority of the
diff. We're left with the collection of non-critical fixes after that.
Overall it looks pretty quiet this time.
Core:
- Clk duty cycle support
- Proper CLK_SET_RATE_GATE support throughout the tree
New Drivers:
- Actions Semi Owl series S700 SoC clk driver

- Allwinner A64 display engine clock support
- support for Rockchip's PX30 SoC
- Amlogic Meson axg PCIe and audio clocks
- Amlogic Meson GEN CLK on gxbb, gxl and axg
Updates:
- remove an unused variable from Exynos4412 ISP driver
- fix a thinko bug in SCMI clk division logic
- add missing of_node_put()s in some i.MX clk drivers
- Tegra SDMMC clk jitter improvements with high speed signaling modes
- SPDX tagging for qcom and cs2000-cp drivers
- stop leaking con ids in __clk_put()
- fix a corner case in fixed factor clk probing where node is in DT
but parent clk is registered much later
- Marvell Armada 3700 clk_pm_cpu_get_parent() had an invalid return
value
- i.MX clk init arrays removed in place of CLK_IS_CRITICAL
- convert to CLK_IS_CRITICAL for i.MX51/53 driver
- fix Tegra BPMP driver oops when xlating a NULL clk
- proper default configuration for vic03 and vde clks on Tegra124
- mark Tegra memory controller clks as critical
- fix array bounds clamp in Tegra's emc determine_rate() op
- Ingenic i2s bit update and allow UDC clk to gate
- fix name of aspeed SDC clk define to have only one 'CLK'
- fix i.MX6QDL video clk parent
- critical clk markings for qcom SDM845
- fix Stratix10 mpu_free_clk and sdmmc_free_clk parents
- mark Rockchip's pclk_rkpwm_pmu as critical clock, due to it
supplying the pwm used to drive the logic supply of the rk3399
core"

git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio
Pull GPIO updates from Linus Walleij:
"This is the bulk of GPIO changes for the v4.19 kernel cycle.
I don't know if anything in particular stands out. Maybe the Aspeed
coprocessor thing from Benji: Aspeed is doing baseboard management
chips (BMC's) for servers etc.
These Aspeed's are ARM processors that exist inside (I guess) Intel
servers, and they are moving forward to using mainline Linux in those.
This is one of the pieces of the puzzle to achive that. They are doing
OpenBMC, it's pretty cool: https://lwn.net/Articles/683320/
Summary:
Core changes:
- Add a new API for explicitly naming GPIO consumers, when needed.
- Don't let userspace set values on input lines. While we do not
think anyone would do this crazy thing we better plug the hole
before someone uses it and think it's a nifty feature.
- Avoid calling chip->request() for unused GPIOs.
New drivers/subdrivers:
- The Mediatek MT7621 is supported which is a big win for OpenWRT and
similar router distributions using this chip, as it seems every
major router manufacturer on the planet has made products using
this chip: https://wikidevi.com/wiki/MediaTek_MT7621
- The Tegra 194 is now supported.
- The IT87 driver now supports IT8786E and IT8718F super-IO chips.
- Add support for Rockchip RK3328 in the syscon GPIO driver.
Driver changes:
- Handle the get/set_multiple() properly on MMIO chips with inverted
direction registers. We didn't have this problem until a new chip
appear that has get/set registers AND inverted direction bits, OK
now we handle it.
- A patch series making more error codes percolate upward properly
for different errors on gpiochip_lock_as_irq().
- Get/set multiple for the OMAP driver, accelerating these multiple
line operations if possible.
- A coprocessor interface for the Aspeed driver. Sometimes a few GPIO
lines need to be grabbed by a co-processor for doing automated
tasks, sometimes they are available as GPIO lines. By adding an
explicit API in this driver we make it possible for the two line
consumers to coexist. (This work was made available on the
ib-aspeed branch, which may be appearing in other pull requests.)
- Implemented .get_direction() and open drain in the SCH311x driver.
- Continuing cleanup of included headers in GPIO drivers"

Utilize -mfentry and -mnop-mcount gcc options together with
-mrecord-mcount to get compiler generated calls to the profiling functions
as nops which are compatible with current -mhotpatch=0,3 approach. At the
same time -mrecord-mcount enables __mcount_loc section generation by
the compiler which allows to avoid using scripts/recordmcount.pl script.

-mcount-nop gcc option generates the calls to the profiling functions
as nops which allows to avoid patching mcount jump with NOP instructions
initially.
-mcount-nop gcc option will be activated if platform selects
HAVE_NOP_MCOUNT and gcc actually supports it.
In addition to that CC_USING_NOP_MCOUNT is defined and could be used by
architectures to adapt ftrace patching behavior.

Currently if CONFIG_FTRACE_MCOUNT_RECORD is enabled -mrecord-mcount
compiler flag support is tested for every Makefile.
Top 4 cc-option usages:
511 -mrecord-mcount
11 -fno-stack-protector
9 -Wno-override-init
2 -fsched-pressure
To address that move cc-option from scripts/Makefile.build to top Makefile
and export CC_USING_RECORD_MCOUNT to be used in original place.
While doing that also add -mrecord-mcount to CC_FLAGS_FTRACE (if gcc
actually supports it).

CC_FLAGS_FTRACE is exported and later used to remove ftrace relevant
build flags from files which should be built without ftrace support.
For that reason add -mfentry to CC_FLAGS_FTRACE as well. That fixes
a problem with vdso32 build on s390, where -mfentry could not be used
together with -m31 flag.
At the same time flags like -pg and -mfentry are not relevant for asm
files, so avoid adding them to KBUILD_AFLAGS.
Introduce CC_FLAGS_USING instead of CC_USING_FENTRY to collect
-DCC_USING_FENTRY (and future alike) which are relevant for both
KBUILD_CFLAGS and KBUILD_AFLAGS.
