In the struct ice_aqc_vsi_props the field port_vlan_flags is an
overloaded term because it is used for both port VLANs (PVLANs) and
regular VLANs. This is an issue and is very confusing especially when
dealing with VFs because normal VLANs and port VLANs are not the same.
To fix this the field was renamed to vlan_flags and all of the #define's
labeled *_PVLAN_* were renamed to *_VLAN_* if they are not specific to
port VLANs.
Also in ice_vsi_manage_vlan_stripping, set the ICE_AQ_VSI_VLAN_MODE_ALL
bit to allow the driver to add a VLAN tag to all packets it sends.

Currently, we use a combination of ilog2 and is_power_of_2() to
calculate the next power of 2 for the qcount. This appears to be causing
a warning on some combinations of GCC and the Linux kernel:
MODPOST 1 modules
WARNING: "____ilog2_NaN" [ice.ko] undefined!
This appears to because because GCC realizes that qcount could be zero
in some circumstances and thus attempts to link against the
intentionally undefined ___ilog2_NaN function.
The order_base_2 function is intentionally defined to return 0 when
passed 0 as an argument, and thus will be safe to use here.
This not only fixes the warning but makes the resulting code slightly
cleaner, and is really what we should have used originally.
Also update the comment to make it more clear that we are rounding up,
not just incrementing the ilog2 of qcount unconditionally.

This patch is a consolidation of multiple bug fixes for control queue
processing.
1) In ice_clean_adminq_subtask() remove unnecessary reads/writes to
registers. The bits PFINT_FW_CTL, PFINT_MBX_CTL and PFINT_SB_CTL
are not set when an interrupt arrives, which means that clearing them
again can be omitted.
2) Get an accurate value in "pending" by re-reading the control queue
head register from the hardware.
3) Fix a corner case involving lost control queue messages by checking
for new control messages (using ice_ctrlq_pending) before exiting the
cleanup routine.

It is not safe to have the string table for statistics change order or
size over the lifetime of a given netdevice. This is because of the
nature of the 3-step process for obtaining stats. First, user space
performs a request for the size of the strings table. Second it performs
a separate request for the strings themselves, after allocating space
for the table. Third, it requests the stats themselves, also allocating
space for the table.
If the size decreased, there is potential to see garbage data or stats
values. In the worst case, we could potentially see stats values become
mis-aligned with their strings, so that it looks like a statistic is
being reported differently than it actually is.
Even worse, if the size increased, there is potential that the strings
table or stats table was not allocated large enough and the stats code
could access and write to memory it should not, potentially resulting in
undefined behavior and system crashes.
It isn't even safe if the size always changes under the RTNL lock. This
is because the calls take place over multiple user space commands, so it
is not possible to hold the RTNL lock for the entire duration of
obtaining strings and stats. Further, not all consumers of the ethtool
API are the user space ethtool program, and it is possible that one
assumes the strings will not change (valid under the current contract),
and thus only requests the stats values when requesting stats in a loop.
Finally, it's not possible in the general case to detect when the size
changes, because it is quite possible that one value which could impact
the stat size increased, while another decreased. This would result in
the same total number of stats, but reordering them so that stats no
longer line up with the strings they belong to. Since only size changes
aren't enough, we would need some sort of hash or token to determine
when the strings no longer match. This would require extending the
ethtool stats commands, but there is no more space in the relevant
structures.
The real solution to resolve this would be to add a completely new API
for stats, probably over netlink.
In the ice driver, the only thing impacting the stats that is not
constant is the number of queues. Instead of reporting stats for each
used queue, report stats for each allocated queue. We do not change the
number of queues allocated for a given netdevice, as we pass this into
the alloc_etherdev_mq() function to set the num_tx_queues and
num_rx_queues.
This resolves the potential bugs at the slight cost of displaying many
queue statistics which will not be activated.

tcp_bbr: PROBE_RTT minor bug fixes
This series includes two minor bug fixes for the TCP BBR PROBE_RTT
mechanism, and one preparatory patch:
(1) A preparatory patch to reorganize the PROBE_RTT logic by refactoring
(into its own function) the code to exit PROBE_RTT, since the next
patch will be using that code in a new context.
(2) Fix: When BBR restarts from idle and if BBR is in PROBE_RTT mode,
BBR should check if it's time to exit PROBE_RTT. If yes, then BBR
should exit PROBE_RTT mode and restore the cwnd to its full value.
(3) Fix: Apply the PROBE_RTT cwnd cap even if the count of fully-ACKed
packets is 0.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
This commit fixes a corner case where TCP BBR would enter PROBE_RTT
mode but not reduce its cwnd. If a TCP receiver ACKed less than one
full segment, the number of delivered/acked packets was 0, so that
bbr_set_cwnd() would short-circuit and exit early, without cutting
cwnd to the value we want for PROBE_RTT.
The fix is to instead make sure that even when 0 full packets are
ACKed, we do apply all the appropriate caps, including the cap that
applies in PROBE_RTT mode.

tcp uses per-cpu (and per namespace) sockets (net->ipv4.tcp_sk) internally
to send some control packets.
1) RST packets, through tcp_v4_send_reset()
2) ACK packets in SYN-RECV and TIME-WAIT state, through tcp_v4_send_ack()
These packets assert IP_DF, and also use the hashed IP ident generator
to provide an IPv4 ID number.
Geoff Alexander reported this could be used to build off-path attacks.
These packets should not be fragmented, since their size is smaller than
IPV4_MIN_MTU. Only some tunneled paths could eventually have to fragment,
regardless of inner IPID.
We really can use zero IPID, to address the flaw, and as a bonus,
avoid a couple of atomic operations in ip_idents_reserve()

responded, and blocks the following commands.
Since the (un)load request commands might be not responded due to other
PFs, the patch also adds the option to skip the blocking upon a failure.

The MFW manages an internal lock to prevent concurrent hardware
(de)initialization of different PFs.
This, together with the busy-waiting for the MFW's responses for commands,
might lead to a deadlock during concurrent load or unload of PFs.
This patch adds the option to sleep within the busy-waiting, and uses it
for the (un)load requests (which are not sent from an interrupt context) to
prevent the possible deadlock.
