7 years agoneigh: Really delete an arp/neigh entry on "ip neigh delete" or "arp -d"
Sowmini Varadhan [Fri, 2 Jun 2017 16:01:49 +0000 (09:01 -0700)]
neigh: Really delete an arp/neigh entry on "ip neigh delete" or "arp -d"

The command
  # arp -s 62.2.0.1 a:b:c:d:e:f dev eth2
adds an entry like the following (listed by "arp -an")
  ? (62.2.0.1) at 0a:0b:0c:0d:0e:0f [ether] PERM on eth2
but the symmetric deletion command
  # arp -i eth2 -d 62.2.0.1
does not remove the PERM entry from the table, and instead leaves behind
  ? (62.2.0.1) at <incomplete> on eth2

The reason is that there is a refcnt of 1 for the arp_tbl itself
(neigh_alloc starts off the entry with a refcnt of 1), thus
the neigh_release() call from arp_invalidate() will (at best) just
decrement the ref to 1, but will never actually free it from the
table.

To fix this, we need to do something like neigh_forced_gc: if
the refcnt is 1 (i.e., on the table's ref), remove the entry from
the table and free it. This patch refactors and shares common code
between neigh_forced_gc and the newly added neigh_remove_one.

A similar issue exists for IPv6 Neighbor Cache entries, and is fixed
in a similar manner by this patch.

====================
net-next: stmmac: add dwmac-sun8i ethernet driver

This patch series add the driver for dwmac-sun8i which handle the Ethernet MAC
present on Allwinner H3/H5/A83T/A64 SoCs.

This driver is the continuation of the sun8i-emac driver.
During the development, it appeared that in fact the hardware was a modified
version of some dwmac.
So the driver is now written as a glue driver for stmmac.

It supports 10/100/1000 Mbit/s speed with half/full duplex.
It can use an internal PHY (MII 10/100) or an external PHY
via RGMII/RMII.

This patch series enable the driver only for the H3/A64/H5 SoC since A83T
doesn't have the necessary clocks present in mainline.

The driver have been tested on the following boards:
- H3 Orange PI PC, BananaPI-M2+
- A64 Pine64, BananaPi-M64
- A83T BananaPI-M3

The first two patchs are some mandatory changes for letting dwmac-sun8i be used.
The following three patchs add the driver and its documentation.
The remaining are DT patch enabling it.

Regards
Corentin Labbe

Changes since v5:
- Added DT patch for NanoPi neo

of interrupts. E.g., when enabling VFs and setting their MSI-x tables.

The driver currently has some very strict assumptions on the order the
entries are placed in the CAM. Specifically, it assumes that all entries
belonging to a PF would be consecutive and in-order in the CAM, and that
the VF entries would then follow. But there's no actual HW constraint
enforcing this assumption [although management firmware does set it
accordingly to same assumption initially].

Since the CAM is re-configurable, there are now SW flows employeed
by other OSes that might cause the assumption to be invalid.
Such flows allow the PF to forfeit some of it's available interrupts
in favor of its VFs or vice versa.
While those are not employeed today by qed, we want to relax the
assumptions as much as we can -
both to allow functionality after PDA as well as allowing future
compatibility where the driver would be loaded after a newer one has
'dirtied' the CAM configuration.

In addition to patches meant for the above relaxation, the series
also contains various cleanups & refactoring for interrupt logic
[most of which is !semantic].

qed: Reset IGU CAM to default on init

The IGU CAM contains an assocaition between hardware SBs
and interrupt lines, and it can be dynamically configured
to allow more interrupts in one entity over another, specifically
for Re-distibution of SBs between a PF and its child VFs.

While we don't yet use this functionality, there are other
clients that do and as such its possible the information
passed from management firmware during initialization in
regard to the possible number of SBs doesn't accurately reflect
the current HW configuration.

The following changes are going to apply to the driver init sequence:

 a. PF is going to re-configure all entries belonging to itself and
    its child VFs in IGU CAM based on the management firmware info
    regarding the number of SBs that are supposed to exist there.

 b. PF is going to stop using the SB resource [management firmware
    provided information] for anything but the initialization.
    Instead, it would use the live-time counters it maintains for
    the numbers.

A PF today holds 2 different arrays - one holding information

the SBs that are used by the protocol drivers.
These arrays aren't really connected - e.g., protocol driver
initializing a given SB would not mark the same SB as occupied
in the HW shadow array.

Move into a single array [at least for PFs] - hold the mapping
of the driver-protocol SBs on the HW entry which they configure.
