Some applications (like GDB) would like to tweak shadow stack state via
ptrace. This allows for existing functionality to continue to work for
seized shadow stack applications. Provide a regset interface for
manipulating the shadow stack pointer (SSP).
There is already ptrace functionality for accessing xstate, but this
does not include supervisor xfeatures. So there is not a completely
clear place for where to put the shadow stack state. Adding it to the
user xfeatures regset would complicate that code, as it currently shares
logic with signals which should not have supervisor features.
Don't add a general supervisor xfeature regset like the user one,
because it is better to maintain flexibility for other supervisor
xfeatures to define their own interface. For example, an xfeature may
decide not to expose all of it's state to userspace, as is actually the
case for shadow stack ptrace functionality. A lot of enum values remain
to be used, so just put it in dedicated shadow stack regset.
The only downside to not having a generic supervisor xfeature regset,
is that apps need to be enlightened of any new supervisor xfeature
exposed this way (i.e. they can't try to have generic save/restore
logic). But maybe that is a good thing, because they have to think
through each new xfeature instead of encountering issues when a new
supervisor xfeature was added.
By adding a shadow stack regset, it also has the effect of including the
shadow stack state in a core dump, which could be useful for debugging.
The shadow stack specific xstate includes the SSP, and the shadow stack
and WRSS enablement status. Enabling shadow stack or WRSS in the kernel
involves more than just flipping the bit. The kernel is made aware that
it has to do extra things when cloning or handling signals. That logic
is triggered off of separate feature enablement state kept in the task
struct. So the flipping on HW shadow stack enforcement without notifying
the kernel to change its behavior would severely limit what an application
could do without crashing, and the results would depend on kernel
internal implementation details. There is also no known use for controlling
this state via ptrace today. So only expose the SSP, which is something
that userspace already has indirect control over.

A control-protection fault is triggered when a control-flow transfer
attempt violates Shadow Stack or Indirect Branch Tracking constraints.
For example, the return address for a RET instruction differs from the copy
on the shadow stack.
There already exists a control-protection fault handler for handling kernel
IBT faults. Refactor this fault handler into separate user and kernel
handlers, like the page fault handler. Add a control-protection handler
for usermode. To avoid ifdeffery, put them both in a new file cet.c, which
is compiled in the case of either of the two CET features supported in the
kernel: kernel IBT or user mode shadow stack. Move some static inline
functions from traps.c into a header so they can be used in cet.c.
Opportunistically fix a comment in the kernel IBT part of the fault
handler that is on the end of the line instead of preceding it.
Keep the same behavior for the kernel side of the fault handler, except for
converting a BUG to a WARN in the case of a #CP happening when the feature
is missing. This unifies the behavior with the new shadow stack code, and
also prevents the kernel from crashing under this situation which is
potentially recoverable.
The control-protection fault handler works in a similar way as the general
protection fault handler. It provides the si_code SEGV_CPERR to the signal
handler.

Currently the attribute cap.max_send_wr and cap.max_recv_wr
sent from user-space during create QP are the provider computed
SQ/RQ depth as opposed to raw values passed from application.
This inhibits computation of an accurate value for max_send_wr
and max_recv_wr for this QP in the kernel which matches the value
returned in user create QP. Also these capabilities needs to be
reported from the driver in query QP.
Add support by extending the ABI to allow the raw cap.max_send_wr and
cap.max_recv_wr to be passed from user-space, while keeping compatibility
for the older scheme.
The internal HW depth and shift needed for the WQs needs to be computed
now for both kernel and user-mode QPs. Add new helpers to assist with this:
irdma_uk_calc_depth_shift_sq, irdma_uk_calc_depth_shift_rq and
irdma_uk_calc_depth_shift_wq.
Consolidate all the user mode QP setup into a new function
irdma_setup_umode_qp which keeps it with its counterpart
irdma_setup_kmode_qp.

accept_ra_min_rtr_lft only considered the lifetime of the default route
and discarded entire RAs accordingly.
This change renames accept_ra_min_rtr_lft to accept_ra_min_lft, and
applies the value to individual RA sections; in particular, router
lifetime, PIO preferred lifetime, and RIO lifetime. If any of those
lifetimes are lower than the configured value, the specific RA section
is ignored.
In order for the sysctl to be useful to Android, it should really apply
to all lifetimes in the RA, since that is what determines the minimum
frequency at which RAs must be processed by the kernel. Android uses
hardware offloads to drop RAs for a fraction of the minimum of all
lifetimes present in the RA (some networks have very frequent RAs (5s)
with high lifetimes (2h)). Despite this, we have encountered networks
that set the router lifetime to 30s which results in very frequent CPU
wakeups. Instead of disabling IPv6 (and dropping IPv6 ethertype in the
WiFi firmware) entirely on such networks, it seems better to ignore the
misconfigured routers while still processing RAs from other IPv6 routers
on the same network (i.e. to support IoT applications).
The previous implementation dropped the entire RA based on router
lifetime. This turned out to be hard to expand to the other lifetimes
present in the RA in a consistent manner; dropping the entire RA based
on RIO/PIO lifetimes would essentially require parsing the whole thing
twice.

Xen 4.17 supports the creation of static evtchns. To allow user space
application to bind static evtchns introduce new ioctl
"IOCTL_EVTCHN_BIND_STATIC". Existing IOCTL doing more than binding
that’s why we need to introduce the new IOCTL to only bind the static
event channels.
Static evtchns to be available for use during the lifetime of the
guest. When the application exits, __unbind_from_irq() ends up being
called from release() file operations because of that static evtchns
are getting closed. To avoid closing the static event channel, add the
new bool variable "is_static" in "struct irq_info" to mark the event
channel static when creating the event channel to avoid closing the
static evtchn.
Also, take this opportunity to remove the open-coded version of the
evtchn close in drivers/xen/evtchn.c file and use xen_evtchn_close().

Currently the bpf_sk_assign helper in tc BPF context refuses SO_REUSEPORT
sockets. This means we can't use the helper to steer traffic to Envoy,
which configures SO_REUSEPORT on its sockets. In turn, we're blocked
from removing TPROXY from our setup.
The reason that bpf_sk_assign refuses such sockets is that the
bpf_sk_lookup helpers don't execute SK_REUSEPORT programs. Instead,
one of the reuseport sockets is selected by hash. This could cause
dispatch to the "wrong" socket:
sk = bpf_sk_lookup_tcp(...) // select SO_REUSEPORT by hash
bpf_sk_assign(skb, sk) // SK_REUSEPORT wasn't executed
Fixing this isn't as simple as invoking SK_REUSEPORT from the lookup
helpers unfortunately. In the tc context, L2 headers are at the start
of the skb, while SK_REUSEPORT expects L3 headers instead.
Instead, we execute the SK_REUSEPORT program when the assigned socket
is pulled out of the skb, further up the stack. This creates some
trickiness with regards to refcounting as bpf_sk_assign will put both
refcounted and RCU freed sockets in skb->sk. reuseport sockets are RCU
freed. We can infer that the sk_assigned socket is RCU freed if the
reuseport lookup succeeds, but convincing yourself of this fact isn't
straight forward. Therefore we defensively check refcounting on the
sk_assign sock even though it's probably not required in practice.

Fixes: cf7fbe660f ("bpf: Add socket assign support")

This change adds a new sysctl accept_ra_min_rtr_lft to specify the
minimum acceptable router lifetime in an RA. If the received RA router
lifetime is less than the configured value (and not 0), the RA is
ignored.
This is useful for mobile devices, whose battery life can be impacted
by networks that configure RAs with a short lifetime. On such networks,
the device should never gain IPv6 provisioning and should attempt to
drop RAs via hardware offload, if available.

This patch adds the capability to filter messages sent by the proc
connector on the event type supplied in the message from the client
to the connector. The client can register to listen for an event type
given in struct proc_input.
This event based filteting will greatly enhance performance - handling
8K exits takes about 70ms, whereas 8K-forks + 8K-exits takes about 150ms
& handling 8K-forks + 8K-exits + 8K-execs takes 200ms. There are currently
9 different types of events, and we need to listen to all of them. Also,
measuring the time using pidfds for monitoring 8K process exits took
much longer - 200ms, as compared to 70ms using only exit notifications of
proc connector.
We also add a new event type - PROC_EVENT_NONZERO_EXIT, which is
only sent by kernel to a listening application when any process exiting,
has a non-zero exit status. This will help the clients like Oracle DB,
where a monitoring process wants notfications for non-zero process exits
so it can cleanup after them.
This kind of a new event could also be useful to other applications like
Google's lmkd daemon, which needs a killed process's exit notification.
The patch takes care that existing clients using old mechanism of not
sending the event type work without any changes.
cn_filter function checks to see if the event type being notified via
proc connector matches the event type requested by client, before
sending(matches) or dropping(does not match) a packet.

The current proc connector code has the foll. bugs - if there are more
than one listeners for the proc connector messages, and one of them
deregisters for listening using PROC_CN_MCAST_IGNORE, they will still get
all proc connector messages, as long as there is another listener.
Another issue is if one client calls PROC_CN_MCAST_LISTEN, and another one
calls PROC_CN_MCAST_IGNORE, then both will end up not getting any messages.
This patch adds filtering and drops packet if client has sent
PROC_CN_MCAST_IGNORE. This data is stored in the client socket's
sk_user_data. In addition, we only increment or decrement
proc_event_num_listeners once per client. This fixes the above issues.
