[Intel-wired-lan] [PATCH S25 01/12] ice: update ethtool stats on-demand

[Intel-wired-lan] [PATCH S25 01/12] ice: update ethtool stats on-demand

[Tony Nguyen]

From: Bruce Allan <bruce.w.allan@intel.com>

Users expect ethtool statistics to be updated on-demand when invoking
'ethtool -S <iface>' instead of providing a snapshot of statistics taken
once a second (the frequency of the watchdog task where stats are currently
updated).  Update stats every time 'ethtool -S <iface>' is run.

Also, fix an indentation style issue and an unnecessary local variable
initialization in ice_get_ethtool_stats() discovered while investigating
the subject issue.

[Intel-wired-lan] [PATCH S25 02/12] ice: Fix issues updating VSI MAC filters

[Tony Nguyen]

From: Akeem G Abodunrin <akeem.g.abodunrin@intel.com>

VSI, especially VF could request to add or remove filter for another VSI,
driver should really guide such request and disallow it.
However, instead of returning error for such malicious request, driver
can simply return success.

In addition, we are not tracking number of MAC filters configured per
VF correctly - and this leads to issue updating VF MAC filters whenever
they were removed and re-configured via bringing VF interface down and
up. Also, since VF could send request to update multiple MAC filters at
once, driver should program those filters individually in the switch, in
order to determine which action resulted to error, and communicate
accordingly to the VF.

So, with this changes, we now track number of filters added right from
when VF resources allocation is done, and could properly add filters for
both trusted and non_trusted VFs, without MAC filters mis-match issue in
the switch...

Also refactor code, so that driver can use new function to add or remove
MAC filters.

[Intel-wired-lan] [PATCH S25 04/12] ice: Fix ethtool port and PFC stats for 4x25G cards

[Tony Nguyen]

From: Usha Ketineni <usha.k.ketineni@intel.com>

This patch fixes the issue where port and PFC statistics counters are
incrementing at the wrong port with 4x25G cards.
Read the GLPRT port registers using lport parameter instead of pf_id to
update the statistics otherwise the pf_ids are flipped for ports 2 and 3
when read from the HW register PF_FUNC_RID and this is expected as per
hardware specification.

[Intel-wired-lan] [PATCH S25 05/12] ice: added sibling head to parse nodes

[Tony Nguyen]

From: Victor Raj <victor.raj@intel.com>

There was a bug in the previous code which never traverses all the
children to get the first node of the requested layer. Add a sibling
head pointer to point the first node of each layer per TC. This helps
traverse easier and quicker and also removes the recursion.

[Intel-wired-lan] [PATCH S25 06/12] ice: Sanitize ice_ena_vsi and ice_dis_vsi

[Tony Nguyen]

From: Anirudh Venkataramanan <anirudh.venkataramanan@intel.com>

1. ndo_open and ndo_stop are implemented by ice_open and ice_stop
   respectively. When enabling/disabling VSIs, just call
   ice_open/ice_stop instead of ndo_open/ndo_stop.

2. Rework logic around rtnl_lock/rtnl_unlock

3. In ice_ena_vsi, remove an unnecessary stack variable and return
   0 instead of err when __ICE_NEEDS_RESTART is not set.

[Tony Nguyen]

From: Jesse Brandeburg <jesse.brandeburg@intel.com>

Add some verbose debugging for dyndbg to help us when
we are having issues with link and/or PHY.

While there, shorten some strings used by locals that
were causing long line wrapping.

[Intel-wired-lan] [PATCH S25 08/12] ice: Introduce a local variable for a VSI in the rebuild path

[Tony Nguyen]

From: Krzysztof Kazimierczak <krzysztof.kazimierczak@intel.com>

When a VSI is accessed inside the ice_for_each_vsi macro in the rebuild
path (ice_vsi_rebuild_all() and ice_vsi_replay_all()), it is referred to
as pf->vsi[i]. Introduce local variables to improve readability.

[Intel-wired-lan] [PATCH S25 09/12] ice: Don't clog kernel debug log with VF MDD events errors

[Tony Nguyen]

From: Akeem G Abodunrin <akeem.g.abodunrin@intel.com>

In case of MDD events on VF, don't clog kernel log with unlimited VF mdd
events message "VF 0 has had 1018 MDD events since last boot" - limit
events log message to 30, based on the observation in some experimenation
with sending malicious packet once, and number of events reported before
device stopped observing MDD events.

Also removed defunct macro "ICE_DFLT_NUM_MDD_EVENTS_ALLOWED" for tracking
number of MDD events allowed before disabling the interface...

[Intel-wired-lan] [PATCH S25 10/12] ice: add validation in OP_CONFIG_VSI_QUEUES VF message

[Tony Nguyen]

From: Michal Swiatkowski <michal.swiatkowski@intel.com>

Check num_queue_pairs to avoid access to unallocated field of
vsi->tx_rings/vsi->rx_rings. Without this validation we can set
vsi->alloc_txq/vsi->alloc_rxq to value smaller than ICE_MAX_BASE_QS_PER_VF
and send this command with num_queue_pairs greater than
vsi->alloc_txq/vsi->alloc_rxq. This lead to access to unallocated memory.

In VF vsi alloc_txq and alloc_rxq should be the same. Get minimum
because looks more readable.

Also add validation for ring_len param. It should be greater than 32 and
be multiple of 32. Incorrect value leads to hang traffic on PF.

[Intel-wired-lan] [PATCH S25 12/12] ice: fix ice_is_tc_ena

[Tony Nguyen]

From: Jacob Keller <jacob.e.keller@intel.com>

ice_is_tc_ena is used to check whether a given traffic class is
enabled. Because there are only 8 traffic classes, the function took
a u8 bitmap. This causes problems because it is cast to an unsigned
long causing a static analysis warning regarding Out-of-bounds read.

Fix this by simply updating ice_is_tc_ena to take an unsigned long.
Passing a u8 to this function should implicitly convert the value.
