Add EEE management to phylink, making use of the phylib implementation.
This will only be used where a MAC driver populates the methods and
capabilities bitfield, otherwise we keep our old behaviour.
Phylink will keep track of the EEE configuration, including the clock
stop abilities at each end of the MAC to PHY link, programming the PHY
appropriately and preserving the LPI configuration should the PHY go
away.
Phylink will call into the MAC driver when LPI needs to be enabled or
disabled, with the requirement that the MAC have LPI disabled prior
to the netdev being brought up (in other words, it will only call
mac_disable_tx_lpi() if it has already called mac_enable_tx_lpi().)
Support for phylink managed EEE is enabled by populating both tx_lpi
MAC operations method pointers, and filling in both LPI interfaces
and capabilities. If the methods are provided but the LPI interfaces
or capabilities remain empty, this indicates to phylink that EEE is
implemented by the driver but the hardware it is driving does not
support EEE, and thus the ethtool set_eee() and get_eee() methods will
return EOPNOTSUPP.
No validation of the LPI timer value is performed by this patch.
For interface modes which do not support LPI, we make no attempt to
manipulate the phylib EEE advertisement, but instead refuse to
activate LPI at the MAC, noting it at debug message level.
We also restrict the advertisement and reported userspace support
linkmode masks according to the lpi_capabilities provided to
phylink by the MAC driver.

Add support for querying whether the PHY allows the transmit xMII clock
to be stopped while in LPI mode. This will be used by phylink to pass

Kuniyuki Iwashima says:
====================
dev: Covnert dev_change_name() to per-netns RTNL.
Patch 1 adds a missing netdev_rename_lock in dev_change_name()
and Patch 2 removes unnecessary devnet_rename_sem there.
Patch 3 replaces RTNL with rtnl_net_lock() in dev_ifsioc(),
and now dev_change_name() is always called under per-netns RTNL.
Given it's close to -rc8 and Patch 1 touches the trivial unlikely
path, can Patch 1 go into net-next ? Otherwise I'll post Patch 2 & 3
separately in the next cycle.

Basically, dev_ifsioc() operates on the passed single netns (except
for netdev notifier chains with lower/upper devices for which we will
need more changes).
Let's hold rtnl_net_lock() for dev_ifsioc().
Now that NETDEV_CHANGENAME is always triggered under rtnl_net_lock()

The tool pp_alloc_fail.py tested error recovery by injecting errors
into the function page_pool_alloc_pages(). The page pool allocation
function page_pool_dev_alloc() does not end up calling
page_pool_alloc_pages(). page_pool_alloc_netmems() seems to be the
function that is called by all of the page pool alloc functions in
the API, so move error injection to that function instead.

Store rtm->rtm_tos in a dscp_t variable, which can then be used for
setting fl4.flowi4_tos and also be passed as parameter of
ip_route_input_rcu().
The .flowi4_tos field is going to be converted to dscp_t to ensure ECN
bits aren't erroneously taken into account during route lookups. Having
a dscp_t variable available will simplify that conversion, as we'll
just have to drop the inet_dscp_to_dsfield() call.
Note that we can't just convert rtm->rtm_tos to dscp_t because this
structure is exported to user space.

Pull tracing fixes from Steven Rostedt:
- Fix a regression in the irqsoff and wakeup latency tracing
The function graph tracer infrastructure has become generic so that
fprobes and BPF can be based on it. As it use to only handle function
graph tracing, it would always calculate the time the function
entered so that it could then calculate the time it exits and give
the length of time the function executed for. But this is not needed
for the other users (fprobes and BPF) and reading the clock adds a
non-negligible overhead, so the calculation was moved into the
function graph tracer logic.
But the irqsoff and wakeup latency tracers, when the "display-graph"
option was set, would use the function graph tracer to calculate the
times of functions during the latency. The movement of the calltime
calculation made the value zero for these tracers, and the output no
longer showed the length of time of each tracer, but instead the
absolute timestamp of when the function returned (rettime - calltime
where calltime is now zero).
Have the irqsoff and wakeup latency tracers also do the calltime
calculation as the function graph tracer does and report the proper
length of the function timings.
- Update the tracing display to reflect the new preempt lazy model
When the system is configured with preempt lazy, the output of the
trace data would state "unknown" for the current preemption model.
Because the lazy preemption model was just added, make it known to
the tracing subsystem too. This is just a one line change.
- Document multiple function graph having slightly different timings
Now that function graph tracer infrastructure is separate, this also
allows the function graph tracer to run in multiple instances (it
wasn't able to do so before). If two instances ran the function graph
tracer and traced the same functions, the timings for them will be
slightly different because each does their own timings and collects
the timestamps differently. Document this to not have people be
confused by it.

When redirecting the split BTF to the vmlinux base BTF, we need to mark
the distilled base struct/union members of split BTF structs/unions in
id_map with BTF_IS_EMBEDDED. This indicates that these types must match
both name and size later. So if a needed composite type, which is the
member of composite type in the split BTF, has a different size in the
base BTF we wish to relocate with, btf__relocate() should error out.

libbpf automatically adjusts autoload for struct_ops programs,
see libbpf.c:bpf_object_adjust_struct_ops_autoload.
For example, if there is a map:
SEC(".struct_ops.link")
struct sched_ext_ops ops = {
.enqueue = foo,
.tick = bar,
};
Both 'foo' and 'bar' would be loaded if 'ops' autocreate is true,
both 'foo' and 'bar' would be skipped if 'ops' autocreate is false.
This means that when veristat processes object file with 'ops',
it would load 4 programs in total: two programs per each
'process_prog' call.
The adjustment occurs at object load time, and libbpf remembers
association between 'ops' and 'foo'/'bar' at object open time.
The only way to persuade libbpf to load one of two is to adjust map
initial value, such that only one program is referenced.
This patch does exactly that, significantly reducing time to process
object files with big number of struct_ops programs.

Recovery Mode is intended to recover from a fatal failure scenario in
which the device is not accessible to the host, meaning the firmware is
non-responsive.
The purpose of the Firmware Recovery Mode is to enable software tools to
update firmware and/or device configuration so the fatal error can be
resolved.
Recovery Mode Firmware supports a limited set of admin commands required
for NVM update.
Recovery Firmware does not support hardware interrupts so a polling mode
is used.
The driver will expose only the minimum set of devlink commands required
for the recovery of the adapter.
Using an appropriate NVM image, the user can recover the adapter using
the devlink flash API.
Prior to 4.20 E810 Adapter Recovery Firmware supports only the update
and erase of the "fw.mgmt" component.
E810 Adapter Recovery Firmware doesn't support selected preservation of
cards settings or identifiers.
The following command can be used to recover the adapter:
$ devlink dev flash <pci-address> <update-image.bin> component fw.mgmt
overwrite settings overwrite identifier
Newer FW versions (4.20 or newer) supports update of "fw.undi" and
"fw.netlist" components.
$ devlink dev flash <pci-address> <update-image.bin>
Tested on Intel Corporation Ethernet Controller E810-C for SFP

On removal of the device or unloading of the kernel module a potential NULL
pointer dereference occurs.
The following sequence deletes the interface:
brcmf_detach()
brcmf_remove_interface()
brcmf_del_if()
Inside the brcmf_del_if() function the drvr->if2bss[ifidx] is updated to
BRCMF_BSSIDX_INVALID (-1) if the bsscfgidx matches.
After brcmf_remove_interface() call the brcmf_proto_detach() function is
called providing the following sequence:
brcmf_detach()
brcmf_proto_detach()
brcmf_proto_msgbuf_detach()
brcmf_flowring_detach()
brcmf_msgbuf_delete_flowring()
brcmf_msgbuf_remove_flowring()
brcmf_flowring_delete()
brcmf_get_ifp()
brcmf_txfinalize()
Since brcmf_get_ip() can and actually will return NULL in this case the
call to brcmf_txfinalize() will result in a NULL pointer dereference inside
brcmf_txfinalize() when trying to update ifp->ndev->stats.tx_errors.
This will only happen if a flowring still has an skb.
Although the NULL pointer dereference has only been seen when trying to
update the tx statistic, all other uses of the ifp pointer have been
guarded as well with an early return if ifp is NULL.

Problem: The x86_64 UEFI doc references Elilo which is an
unmaintained/orphaned bootloader project. Also, on x86_64 a bootloader
is technically not actually required since there is support for the
Linux EFI stub.
Solution: Remove the references to Elilo from the doc and refer to the
EFI stub doc page, update steps accordingly, and add more details about
creation of the EFI partition to improve clarity.
