Currently, packets dropped by pfifo_fast due to queue overflow are
marked with a generic SKB_DROP_REASON_QDISC_DROP in __dev_xmit_skb().
This patch adds explicit drop reason SKB_DROP_REASON_QDISC_OVERLIMIT
for queue-full cases, providing better distinction from other qdisc drops.

This patch introduces is_bnode_offset_valid() method that checks
the requested offset value. Also, it introduces
check_and_correct_requested_length() method that checks and
correct the requested length (if it is necessary). These methods
are used in hfs_bnode_read(), hfs_bnode_write(), hfs_bnode_clear(),
hfs_bnode_copy(), and hfs_bnode_move() with the goal to prevent
the access out of allocated memory and triggering the crash.

Kees Cook says:
====================
net: Add sockaddr_inet unified address structure
Repeating patch 1, as it has the rationale:
There are cases in networking (e.g. wireguard, sctp) where a union is
used to provide coverage for either IPv4 or IPv6 network addresses,
and they include an embedded "struct sockaddr" as well (for "sa_family"
and raw "sa_data" access). The current struct sockaddr contains a
flexible array, which means these unions should not be further embedded
in other structs because they do not technically have a fixed size (and
are generating warnings for the coming -Wflexible-array-not-at-end flag
addition). But the future changes to make struct sockaddr a fixed size
(i.e. with a 14 byte sa_data member) make the "sa_data" uses with an IPv6
address a potential place for the compiler to get upset about object size
mismatches. Therefore, we need a sockaddr that cleanly provides both an
sa_family member and an appropriately fixed-sized sa_data member that does
not bloat member usage via the potential alternative of sockaddr_storage
to cover both IPv4 and IPv6, to avoid unseemly churn in the affected code
bases.
Introduce sockaddr_inet as a unified structure for holding both IPv4 and
IPv6 addresses (i.e. large enough to accommodate sockaddr_in6).
The structure is defined in linux/in6.h since its max size is sized
based on sockaddr_in6 and provides a more specific alternative to the
generic sockaddr_storage for IPv4 with IPv6 address family handling.
The "sa_family" member doesn't use the sa_family_t type to avoid needing
layer violating header inclusions.
Also includes the replacements for wireguard and sctp.

Remote IPsec tunnel endpoint may refer to a network segment that is
not directly connected to the host. In such a case, IPsec tunnel
endpoints are connected to a router and reachable via a routing path.
In IPsec packet offload mode, HW is initialized with the MAC address
of both IPsec tunnel endpoints.
Extend the current IPsec init MACs procedure to resolve nexthop for
routed networks. Direct neighbour lookup and probe is still used
for directly connected networks and as a fallback mechanism if fib
lookup fails.

Rework the read and write code paths in the driver to support operation
in atomic contexts. To achieve this, the driver must not rely on IRQs
or perform any scheduling, e.g., via a sleep or schedule routine.
Implement atomic, sleep-free, and IRQ-less operation. This increases
complexity but is necessary for atomic I2C transfers required by some
hardware configurations, e.g., to trigger reboots on an external PMIC chip.

are always powered on, i.e. PD_BUS or PD_PMU. These always powered
on power domains have typically not been described in the device tree.
Because these power domains have been left out of the device tree there
has not been any real need to properly describe the I2C controllers
power domain.
On RK3528 the I2C controllers are spread out among the described
PD_RKVENC, PD_VO and PD_VPU power domains. However, one I2C controller
belong to an undescribed always powered on power domain.

interruptions are only triggered at privilege levels 2 and 3. The
kernel executes at privilege level 0, so __get_user() never triggers
a read access interruption (code 26). Thus, it is currently possible
for user code to access a read protected address via a system call.
Fix this by probing read access rights at privilege level 3 (PRIV_USER)
and setting __gu_err to -EFAULT (-14) if access isn't allowed.
Note the cmpiclr instruction does a 32-bit compare because COND macro
doesn't work inside asm.

We use load and stbys,e instructions to trigger memory reference
interruptions without writing to memory. Because of the way read
access support is implemented, read access interruptions are only
triggered at privilege levels 2 and 3. The kernel and gateway
page execute at privilege level 0, so this code never triggers
a read access interruption. Thus, it is currently possible for
user code to execute a LWS compare and swap operation at an
address that is read protected at privilege level 3 (PRIV_USER).
Fix this by probing read access rights at privilege level 3 and
branching to lws_fault if access isn't allowed.

Because of the way the _PAGE_READ is handled in the parisc PTE, an
access interruption is not generated when the kernel reads from a
region where the _PAGE_READ is zero. The current code was written
assuming read access faults would also occur in the kernel.
This change adds user access checks to raw_copy_from_user(). The
prober_user() define checks whether user code has read access to
a virtual address. Note that page faults are not handled in the
exception support for the probe instruction. For this reason, we
precede the probe by a ldb access check.

The following testcase exposed a problem with our read access checks
in get_user() and raw_copy_from_user():
#include <stdint.h>
#include <stddef.h>
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <unistd.h>
#include <errno.h>
#include <sys/mman.h>
#include <sys/types.h>
int main(int argc, char **argv)
{
unsigned long page_size = sysconf(_SC_PAGESIZE);
char *p = malloc(3 * page_size);
char *p_aligned;
/* initialize memory region. If not initialized, write syscall below will correctly return EFAULT. */
if (1)
memset(p, 'X', 3 * page_size);
p_aligned = (char *) ((((uintptr_t) p) + (2*page_size - 1)) & ~(page_size - 1));
/* Drop PROT_READ protection. Kernel and userspace should fault when accessing that memory region */
mprotect(p_aligned, page_size, PROT_NONE);
/* the following write() should return EFAULT, since PROT_READ was dropped by previous mprotect() */
int ret = write(2, p_aligned, 1);
if (!ret || errno != EFAULT)
printf("\n FAILURE: write() did not returned expected EFAULT value\n");
return 0;
}
Because of the way _PAGE_READ is handled, kernel code never generates
a read access fault when it access a page as the kernel privilege level
is always less than PL1 in the PTE.
This patch reworks the comments in the make_insert_tlb macro to try
to make this clearer.

Many of the original rtla tests included durations of 1 minute and 30
seconds. Experience has shown this is unnecessary, since 10 seconds as
waiting time for samples to appear.
Change duration of all rtla tests to at most 10 seconds. This speeds up
testing significantly.

Add argument to the check command in the test suite that takes a regular
expression that the output of rtla command is checked against. This
allows testing for specific information in rtla output in addition
to checking the return value.
Two minor improvements are included: running rtla with "eval" so that
arguments with spaces can be passed to it via shell quotations, and
the stdout of pushd and popd is suppressed to clean up the test output.

Implement actions on end next to actions on threshold. A new option,
--on-end is added, parallel to --on-threshold. Instead of being
executed whenever a latency threshold is reached, it is executed at the
end of the measurement.
For example:
$ rtla timerlat hist -d 5s --on-end trace
will save the trace output at the end.
All actions supported by --on-threshold are also supported by --on-end,
except for continue, which does nothing with --on-end.

Introduce option to resume tracing after a latency threshold overflow.
The option is implemented as an action named "continue".
Example:
$ rtla timerlat top -q -T 200 -d 1s --on-threshold \
exec,command="echo Threshold" --on-threshold continue
Threshold
Threshold
Threshold
Timer Latency
...
The feature is supported for both hist and top. After the continue
action is executed, processing of the list of actions is stopped and
tracing is resumed.

Currently, rtla-timerlat BPF program uses a global variable stored in a
.bss section to store whether tracing has been stopped.
Move the information to a separate map, so that it is easily writable
from userspace, and add a function that clears the value, resuming
tracing after it has been stopped.
