This patch fixes a bug introduced with the addition of the per queue
ITR feature support in ethtool.  With that addition, there were
functions added which converted the ITR settings to binary values.
The IS_ENABLED macros that run on those values check whether a bit
is set or not and with the value being binary, the bit check always
returned ITR disabled which prevents any updating of the ITR rate.
This patch fixes the problem by changing the functions to return the
current ITR value instead and renaming it to better reflect
its function.  These functions now provide a value which will be
accurately asessed and update the ITR as intended.

When the i40evf_remove() calls netdev close, the device doesn't actually
close - it schedules the work for the watchdog to perform. Since we're
stopping the watchdog, this work doesn't get done. However, we're
resetting the part, so we can free resources after the reset request has
gone through. This plugs a memory leak.

This patch adds a call to the mac_address_write admin q function during
power down to update the PRTPM_SAH/SAL registers with the MC_MAG_EN bit
thus enabling multicast magic packet wakeup.

A FW workaround is needed to write the multicast magic wake up enable
bit in the PRTPM_SAH register. The FW expects the mac address write
admin q cmd to be called first with one of the WRITE_TYPE_LAA flags
and then with the multicast relevant flags.

*Note: This solution only works for X722 devices currently. A PFR will
clear the previously mentioned bit by default, but X722 has support for a
WOL_PRESERVE_ON_PFR flag which prevents the bit from being cleared. Once
other devices support this flag, this solution should work as well.

There exists a bug in which the driver is unable to exit overflow
promiscuous mode after having added "too many" mac filters.  It is
expected that after triggering overflow promiscuous, removing the
failed/extra filters should then disable overflow promiscuous mode.

The bug exists because we were intentionally skipping the sync_vsi_filter
path in cases where we were removing failed filters since they shouldn't
have been added to the firmware in the first place, however we still
need to go through the sync_vsi_filter code path to determine whether or
not it is ok to exit overflow promiscuous mode.  This patch fixes the
bug by making sure we go through the sync_vsi_filter path in cases of
failed filters.

On EF10, hardware filter IDs are 13 bits, but in some places we store
 32-bit "full filter IDs" in which higher order bits encode the filter
 match-priority.  This could cause a filter to have a full filter ID of
 0xffff, which is also the value EFX_EF10_FILTER_ID_INVALID which we use
 in 16-bit "short" filter IDs (without match-priority bits).  This would
 occur if the hardware filter ID was 0x1fff and the match-priority was 7.
Unfortunately, some code that checks for EFX_EF10_FILTER_ID_INVALID can
 be called on full filter IDs, and will WARN_ON if this ever happens.
So, since we have plenty of spare bits in the full filter ID, this patch
 shifts the priority bits left one bit when constructing the full filter
 IDs, ensuring that the 0x2000 bit of a full filter ID will always be 0
 and thus no full filter ID can ever equal EFX_EF10_FILTER_ID_INVALID.

This patch also replaces open-coded full<->short filter ID conversions
 with calls to functions, thus keeping the definition of the full filter
 ID format in one place.

and last also improving JITs is to make generated images
visible to the kernel and kallsyms, so they can be

Thanks a lot!

Long standing issue with JITed programs is that stack traces from
function tracing check whether a given address is kernel code
through {__,}kernel_text_address(), which checks for code in core
kernel, modules and dynamically allocated ftrace trampolines. But
what is still missing is BPF JITed programs (interpreted programs
are not an issue as __bpf_prog_run() will be attributed to them),
thus when a stack trace is triggered, the code walking the stack
won't see any of the JITed ones. The same for address correlation
done from user space via reading /proc/kallsyms. This is read by
tools like perf, but the latter is also useful for permanent live
tracing with eBPF itself in combination with stack maps when other
eBPF types are part of the callchain. See offwaketime example on
dumping stack from a map.

This work tries to tackle that issue by making the addresses and
symbols known to the kernel. The lookup from *kernel_text_address()
is implemented through a latched RB tree that can be read under
RCU in fast-path that is also shared for symbol/size/offset lookup
for a specific given address in kallsyms. The slow-path iteration
through all symbols in the seq file done via RCU list, which holds
a tiny fraction of all exported ksyms, usually below 0.1 percent.
Function symbols are exported as bpf_prog_<tag>, in order to aide
debugging and attribution. This facility is currently enabled for
root-only when bpf_jit_kallsyms is set to 1, and disabled if hardening
is active in any mode. The rationale behind this is that still a lot
of systems ship with world read permissions on kallsyms thus addresses
should not get suddenly exposed for them. If that situation gets
much better in future, we always have the option to change the
default on this. Likewise, unprivileged programs are not allowed
to add entries there either, but that is less of a concern as most
such programs types relevant in this context are for root-only anyway.
If enabled, call graphs and stack traces will then show a correct
attribution; one example is illustrated below, where the trace is
now visible in tooling such as perf script --kallsyms=/proc/kallsyms
and friends.

This series tackles the problem of table allocation failures during

This series deals with this by introducing nested tables.

The first two patches removes manual hash table walks which cannot
work on a nested table.

The final patch introduces nested tables.

This patch adds code that handles GFP_ATOMIC kmalloc failure on
insertion.  As we cannot use vmalloc, we solve it by making our
hash table nested.  That is, we allocate single pages at each level
and reach our desired table size by nesting them.

When a nested table is created, only a single page is allocated
at the top-level.  Lower levels are allocated on demand during
insertion.  Therefore for each insertion to succeed, only two
(non-consecutive) pages are needed.

After a nested table is created, a rehash will be scheduled in
order to switch to a vmalloced table as soon as possible.  Also,
the rehash code will never rehash into a nested table.  If we
detect a nested table during a rehash, the rehash will be aborted
and a new rehash will be scheduled.

it's doing a manual walk over an rhashtable.  This is broken as
an rhashtable can be resized and if you manually walk over it
during a resize then you may miss entries.

Secondly it's missing memory barriers as previously the code used
spinlocks which provide the barriers implicitly.

net/sched: Reflect HW offload status in classifiers

Currently there is no way of querying whether a filter is
offloaded to HW or not when using "both" policy (where none
of skip_sw or skip_hw flags are set by user-space).

Added two new flags, "in hw" and "not in hw" such that user space
can determine if a filter is actually offloaded to hw. The "in hw"
UAPI semantics was chosen so it's similar to the "skip hw" flag logic.

If none of these two flags are set, this signals running
over older kernel.

As an example, add one vlan push + fwd rule, one matchall rule and one u32 rule
without any flags, and another vlan + fwd skip_sw rule, such that the different TC
classifier attempt to offload all of them -- all over mlx5 SRIOV VF rep:

Since that VF rep doesn't offload matchall/u32 and can currently offload
only one vlan push rule we expect three of the rules not to be offloaded:

filter protocol ip pref 99 u32
filter protocol ip pref 99 u32 fh 800: ht divisor 1
filter protocol ip pref 99 u32 fh 800::1 order 1 key ht 800 bkt 0 flowid 800:1 not in_hw
  match c0a80100/ffffff00 at 12
	action order 1: gact action drop
	 random type none pass val 0
	 index 8 ref 1 bind 1

filter protocol all pref 49150 matchall
filter protocol all pref 49150 matchall handle 0x1
  not in_hw
	action order 1: mirred (Egress Mirror to device veth1) pipe
 	index 27 ref 1 bind 1

filter protocol ip pref 49151 flower
filter protocol ip pref 49151 flower handle 0x1
  indev eth2_0
  dst_mac e4:11:22:33:44:51
  src_mac e4:11:22:33:44:50

  not in_hw
	action order 1:  vlan push id 53 protocol 802.1Q priority 0 pipe
	 index 20 ref 1 bind 1

	action order 2: mirred (Egress Redirect to device eth2) stolen
 	index 26 ref 1 bind 1

filter protocol ip pref 49152 flower
filter protocol ip pref 49152 flower handle 0x1
  indev eth2_0
  dst_mac e4:1d:2d:a5:f3:9d
  src_mac e4:11:22:33:44:50
  eth_type ipv4
  skip_sw
  in_hw
	action order 1:  vlan push id 52 protocol 802.1Q priority 0 pipe
	 index 19 ref 1 bind 1

	action order 2: mirred (Egress Redirect to device eth2) stolen
 	index 25 ref 1 bind 1

v3 --> v4 changes:
 - removed extra parenthesis (Dave)

v2 --> v3 changes:
 - fixed the matchall dump flags patch to do proper checks (Jakub)
 - added the same proper checks to flower where they were missing
 - that flower patch was added as #1 and hence all the other patches are offed-by-one

v1 --> v2 changes:
 - applied feedback from Jakub and Dave -- where none of the skip flags were set,
   the suggested approach didn't allow user space to distringuish between old kernel
   to a case when offloading to HW worked fine.
