macsec: fix NULL dereference in macsec_upd_offload()
macsec_upd_offload() gets the value of MACSEC_OFFLOAD_ATTR_TYPE
without checking its presence in the request message, and this causes
a NULL dereference. Fix it rejecting any configuration that does not
include this attribute.

net: dsa: bcm_sf2: Ensure correct sub-node is parsed
When the bcm_sf2 was converted into a proper platform device driver and
used the new dsa_register_switch() interface, we would still be parsing
the legacy DSA node that contained all the port information since the
platform firmware has intentionally maintained backward and forward
compatibility to client programs. Ensure that we do parse the correct
node, which is "ports" per the revised DSA binding.

net: dsa: bcm_sf2: Do not register slave MDIO bus with OF
We were registering our slave MDIO bus with OF and doing so with
assigning the newly created slave_mii_bus of_node to the master MDIO bus
controller node. This is a bad thing to do for a number of reasons:
- we are completely lying about the slave MII bus is arranged and yet we
still want to control which MDIO devices it probes. It was attempted
before to play tricks with the bus_mask to perform that:
https://www.spinics.net/lists/netdev/msg429420.html but the approach
was rightfully rejected
- the device_node reference counting is messed up and we are effectively
doing a double probe on the devices we already probed using the
master, this messes up all resources reference counts (such as clocks)
The proper fix for this as indicated by David in his reply to the
thread above is to use a platform data style registration so as to
control exactly which devices we probe:
https://www.spinics.net/lists/netdev/msg430083.html
By using mdiobus_register(), our slave_mii_bus->phy_mask value is used
as intended, and all the PHY addresses that must be redirected towards
our slave MDIO bus is happening while other addresses get redirected
towards the master MDIO bus.

ipv6: rpl: fix loop iteration
This patch fix the loop iteration by not walking over the last
iteration. The cmpri compressing value exempt the last segment. As the
code shows the last iteration will be overwritten by cmpre value
handling which is for the last segment.
I think this doesn't end in any bufferoverflows because we work on worst
case temporary buffer sizes but it ends in not best compression settings
in some cases.

tun: Don't put_page() for all negative return values from XDP program
When an XDP program is installed, tun_build_skb() grabs a reference to
the current page fragment page if the program returns XDP_REDIRECT or
XDP_TX. However, since tun_xdp_act() passes through negative return
values from the XDP program, it is possible to trigger the error path by
mistake and accidentally drop a reference to the fragments page without
taking one, leading to a spurious free. This is believed to be the cause
of some KASAN use-after-free reports from syzbot [1], although without a
reproducer it is not possible to confirm whether this patch fixes the
problem.
Ensure that we only drop a reference to the fragments page if the XDP
transmit or redirect operations actually fail.

netfilter: ipset: Pass lockdep expression to RCU lists
ip_set_type_list is traversed using list_for_each_entry_rcu outside an RCU read-side critical section but under the protection of ip_set_type_mutex. Hence, add corresponding lockdep expression to silence false-positive warnings, and harden RCU lists.

netfilter: xt_IDLETIMER: target v1 - match Android layout
Android has long had an extension to IDLETIMER to send netlink messages to userspace, see: https://android.googlesource.com/kernel/common/+/refs/heads/android-mainline/include/uapi/linux/netfilter/xt_IDLETIMER.h#42 Note: this is idletimer target rev 1, there is no rev 0 in the Android common kernel sources, see registration at: https://android.googlesource.com/kernel/common/+/refs/heads/android-mainline/net/netfilter/xt_IDLETIMER.c#483 When we compare that to upstream's new idletimer target rev 1: https://git.kernel.org/pub/scm/linux/kernel/git/pablo/nf-next.git/tree/include/uapi/linux/netfilter/xt_IDLETIMER.h#n46 We immediately notice that these two rev 1 structs are the same size and layout, and that while timer_type and send_nl_msg are differently named and serve a different purpose, they're at the same offset. This makes them impossible to tell apart - and thus one cannot know in a mixed Android/vanilla environment whether one means timer_type or send_nl_msg. Since this is iptables/netfilter uapi it introduces a problem between iptables (vanilla vs Android) userspace and kernel (vanilla vs Android) if the two don't match each other. Additionally when at some point in the future Android picks up 5.7+ it's not at all clear how to resolve the resulting merge conflict. Furthermore, since upgrading the kernel on old Android phones is pretty much impossible there does not seem to be an easy way out of this predicament. The only thing I've been able to come up with is some super disgusting kernel version >= 5.7 check in the iptables binary to flip between different struct layouts. By adding a dummy field to the vanilla Linux kernel header file we can force the two structs to be compatible with each other. Long term I think I would like to deprecate send_nl_msg out of Android entirely, but I haven't quite been able to figure out exactly how we depend on it. It seems to be very similar to sysfs notifications but with some extra info. Currently it's actually always enabled whenever Android uses the IDLETIMER target, so we could also probably entirely remove it from the uapi in favour of just always enabling it, but again we can't upgrade old kernels already in the field. (Also note that this doesn't change the structure's size, as it is simply fitting into the pre-existing padding, and that since 5.7 hasn't been released yet, there's still time to make this uapi visible change) Cc: Manoj Basapathi <manojbm@codeaurora.org> Cc: Subash Abhinov Kasiviswanathan <subashab@codeaurora.org> Signed-off-by: Maciej Żenczykowski <maze@google.com> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org> |

netfilter: nf_tables: do not update stateful expressions if lookup is inverted
Initialize set lookup matching element to NULL. Otherwise, the NFT_LOOKUP_F_INV flag reverses the matching logic and it leads to deference an uninitialized pointer to the matching element. Make sure element data area and stateful expression are accessed if there is a matching set element. This patch undoes |

netfilter: nft_set_rbtree: Drop spurious condition for overlap detection on insertion
Case a1. for overlap detection in __nft_rbtree_insert() is not a valid
one: start-after-start is not needed to detect any type of interval
overlap and it actually results in a false positive if, while
descending the tree, this is the only step we hit after starting from
the root.
This introduced a regression, as reported by Pablo, in Python tests
cases ip/ip.t and ip/numgen.t:
ip/ip.t: ERROR: line 124: add rule ip test-ip4 input ip hdrlength vmap { 0-4 : drop, 5 : accept, 6 : continue } counter: This rule should not have failed.
ip/numgen.t: ERROR: line 7: add rule ip test-ip4 pre dnat to numgen inc mod 10 map { 0-5 : 192.168.10.100, 6-9 : 192.168.20.200}: This rule should not have failed.
Drop case a1. and renumber others, so that they are a bit clearer. In
order for these diagrams to be readily understandable, a bigger rework
is probably needed, such as an ASCII art of the actual rbtree (instead
of a flattened version).
Shell script test sets/0044interval_overlap_0 should cover all
possible cases for false negatives, so I consider that test case still
sufficient after this change.
v2: Fix comments for cases a3. and b3.

powerpc updates for 5.7
- A large series from Nick for 64-bit to further rework our exception vectors,
and rewrite portions of the syscall entry/exit and interrupt return in C. The
result is much easier to follow code that is also faster in general.
- Cleanup of our ptrace code to split various parts out that had become badly
intertwined with #ifdefs over the years.
- Changes to our NUMA setup under the PowerVM hypervisor which should
hopefully avoid non-sensical topologies which can lead to warnings from the
workqueue code and other problems.
- MAINTAINERS updates to remove some of our old orphan entries and update the
status of others.
- Quite a few other small changes and fixes all over the map.

There's not much to see in the core framework this time around. Instead the
majority of the diff is the normal collection of driver additions for new SoCs
and non-critical clk data fixes and updates. The framework must be middle aged.
The two biggest directories in the diffstat show that the Qualcomm and Unisoc
support added a handful of big drivers for new SoCs but that's not really the
whole story because those new drivers tend to add large numbers of lines of clk
data. There's a handful of AT91 clk drivers added this time around too and a
bunch of improvements to drivers like the i.MX driver. All around lots of
updates and fixes in various clk drivers which is good to see.
The core framework has only one real major change which has been baking in next
for the past couple months. It fixes the framework so that it stops caching a
clk's phase when the phase clk_op returns an error. Before this change we would
consider some negative errno as a phase and that just doesn't make sense.
Core:
- Don't show clk phase when it is invalid
New Drivers:
- Add support for Unisoc SC9863A clks
- Qualcomm SM8250 RPMh and MSM8976 RPM clks
- Qualcomm SM8250 Global Clock Controller (GCC) support
- Qualcomm SC7180 Modem Clock Controller (MSS CC) support
- EHRPWM's TimeBase clock(TBCLK) for TI AM654 SoCs
- Support PMC clks on at91sam9n12, at91rm9200, sama5d3, and at91sam9g45 SoCs
Updates:
- GPU GX GDSC support on Qualcomm sc7180
- Fixes and improvements for the Marvell MMP2/MMP3 SoC clk drivers
- A series from Anson to convert i.MX8 clock bindings to json-schema
- Update i.MX pll14xx driver to include new frequency entries for pll1443x table,
and return error for invalid PLL type
- Add missing of_node_put() call for a number of i.MX clock drivers
- Drop flag CLK_IS_CRITICAL from 'A53_CORE' mux clock, as we already
have the flag on its child cpu clock
- Fix a53 cpu clock for i.MX8 drivers to get it source from ARM PLL
via CORE_SEL slice, and source from A53 CCM clk root when we need to
change ARM PLL frequency. Thus, we can support core running above
1GHz safely
- Update i.MX pfdv2 driver to check zero rate and use determine_rate for
getting the best rate
- Add CLKO2 for imx8mm, SNVS clock for imx8mn, and PXP clock for imx7d
- Remove PMC clks from Tegra clk driver
- Improved clock/reset handling for the Renesas R-Car USB2 Clock Selector
- Conversion to json-schema of the Renesas CPG/MSSR DT bindings
- Add Crypto clocks on Renesas R-Car M3-W/W+, M3-N, E3, and D3
- Add RPC (QSPI/HyperFLASH) clocks on Renesas R-Car H3, M3-W/W+, and M3-N
- Update Amlogic audio clock gate hierarchy for meson8 and gxbb
- Update Amlogic g12a spicc clock sources
- Support for Ingenic X1000 TCU clks

New tracing features:
- The ring buffer is no longer disabled when reading the trace file.
The trace_pipe file was made to be used for live tracing and reading
as it acted like the normal producer/consumer. As the trace file
would not consume the data, the easy way of handling it was to just
disable writes to the ring buffer. This came to a surprise to the
BPF folks who complained about lost events due to reading.
This is no longer an issue. If someone wants to keep the old disabling
there's a new option "pause-on-trace" that can be set.
- New set_ftrace_notrace_pid file. PIDs in this file will not be traced
by the function tracer. Similar to set_ftrace_pid, which makes the
function tracer only trace those tasks with PIDs in the file, the
set_ftrace_notrace_pid does the reverse.
- New set_event_notrace_pid file. PIDs in this file will cause events
not to be traced if triggered by a task with a matching PID.
Similar to the set_event_pid file but will not be traced.
Note, sched_waking and sched_switch events may still be trace if
one of the tasks referenced by those events contains a PID that
is allowed to be traced.
Tracing related features:
- New bootconfig option, that is attached to the initrd file.

Merge tag 'trace-v5.7' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace
Pull tracing updates from Steven Rostedt:
"New tracing features:
- The ring buffer is no longer disabled when reading the trace file.
The trace_pipe file was made to be used for live tracing and
reading as it acted like the normal producer/consumer. As the trace
file would not consume the data, the easy way of handling it was to
just disable writes to the ring buffer.
This came to a surprise to the BPF folks who complained about lost
events due to reading. This is no longer an issue. If someone wants
to keep the old disabling there's a new option "pause-on-trace"
that can be set.
- New set_ftrace_notrace_pid file. PIDs in this file will not be
traced by the function tracer.
Similar to set_ftrace_pid, which makes the function tracer only
trace those tasks with PIDs in the file, the set_ftrace_notrace_pid
does the reverse.
- New set_event_notrace_pid file. PIDs in this file will cause events
not to be traced if triggered by a task with a matching PID.
Similar to the set_event_pid file but will not be traced. Note,
sched_waking and sched_switch events may still be traced if one of
the tasks referenced by those events contains a PID that is allowed
to be traced.
Tracing related features:
- New bootconfig option, that is attached to the initrd file.
If bootconfig is on the command line, then the initrd file is
searched looking for a bootconfig appended at the end.
- New GPU tracepoint infrastructure to help the gfx drivers to get
off debugfs (acked by Greg Kroah-Hartman)
And other minor updates and fixes"

clocksource/drivers/timer-vf-pit: Add missing parenthesis
Recently all usage of setup_irq() was replaced by request_irq(). The
replacement in timer-vf-pit.c missed closing parentheses resulting in a build
error (vf610m4_defconfig). Fix it.
