net: sched: propagate extack to cls offloads on destroy and only with skip_sw
This series some of Jiri's comments and the fact that today drivers
may produce extack even if there is no skip_sw flag (meaning the
driver failure is not really a problem), and warning messages will
only confuse the users.
First patch propagates extack to destroy as requested by Jiri, extack
is then propagated to the driver callback for each classifier. I chose
not to provide the extack on error paths. As a rule of thumb it seems
best to keep the extack of the condition which caused the error. E.g.
err = this_will_fail(arg, extack);
if (err) {
undo_things(arg, NULL /* don't pass extack */);
return err;
}
Note that NL_SET_ERR_MSG() will ignore the message if extack is NULL.
I was pondering whether we should make NL_SET_ERR_MSG() refuse to
overwrite the msg, but there seem to be cases in the tree where extack
is set like this:
err = this_will_fail(arg, extack);
if (err) {
undo_things(arg, NULL /* don't pass extack */);
NL_SET_ERR_MSG(extack, "extack is set after undo call :/");
return err;
}
I think not passing extack to undo calls is reasonable.
v2:
- rename the temporary tc_cls_common_offload_init().

Problem description:
After ethernet cable connect and disconnect for several iterations on a
device with i210, tx timestamp will stop being put into the socket.
Steps to reproduce:
1. Setup a device with i210 and wire it to a 802.1AS capable switch (
Extreme Networks Summit x440 is used in our case)
2. Have the gptp daemon running on the device and make sure it is synced
with the switch
3. Have the switch disable and enable the port, wait for the device gets
resynced with the switch
4. Iterates step 3 until the device is not albe to get resynced
5. Review the log in dmesg and you will see warning message "igb : clearing
Tx timestamp hang"
Root cause:
If ptp_tx_work() gets scheduled just before the port gets disabled, a LINK
DOWN event will be processed before ptp_tx_work(), which may cause timeout
in ptp_tx_work(). In the timeout logic, the TSYNCTXCTL's TXTT bit (Transmit
timestamp valid bit) is not cleared, causing no new timestamp loaded to
TXSTMP register. Consequently therefore, no new interrupt is triggerred by
TSICR.TXTS bit and no more Tx timestamp send to the socket.

Before libvirt modifies the MAC address and vlan tag for an SRIOV VF
for use by a virtual machine (either using vfio device assignment or
macvtap passthru mode), it saves the current MAC address and vlan tag
so that it can reset them to their original value when the guest is
done. Libvirt can't leave the VF MAC set to the value used by the
now-defunct guest since it may be started again later using a
different VF, but it certainly shouldn't just pick any random value,
either. So it saves the state of everything prior to using the VF, and
resets it to that.
The igb driver initializes the MAC addresses of all VFs to
00:00:00:00:00:00, and reports that when asked (via an RTM_GETLINK
netlink message, also visible in the list of VFs in the output of "ip
link show"). But when libvirt attempts to restore the MAC address back
to 00:00:00:00:00:00 (using an RTM_SETLINK netlink message) the kernel
responds with "Invalid argument".
Forbidding a reset back to the original value leaves the VF MAC at the
value set for the now-defunct virtual machine. Especially on a system
with NetworkManager enabled, this has very bad consequences, since
NetworkManager forces all interfacess to be IFF_UP all the time - if
the same virtual machine is restarted using a different VF (or even on
a different host), there will be multiple interfaces watching for
traffic with the same MAC address.
To allow libvirt to revert to the original state, we need a way to
remove the administrative set MAC on a VF, to allow normal host
operation again, and to reset/overwrite the VF MAC via VF netdev.
This patch implements the outlined scenario by allowing to set the
VF MAC to 00:00:00:00:00:00 via RTM_SETLINK on the PF.
igb_ndo_set_vf_mac resets the IGB_VF_FLAG_PF_SET_MAC flag to 0,
so it's possible to reset the VF MAC back to the original value via
the VF netdev.
Note: Recent patches to libvirt allow for a workaround if the NIC
isn't capable of resetting the administrative MAC back to all 0, but
in theory the NIC should allow resetting the MAC in the first place.

One was that ORC didn't know how to handle the ftrace callbacks in general

happens from the function tracer would produce no results (that includes
killing the max stack size tracer). I added a check to the ORC unwinder to
see if the trampoline belonged to ftrace, and if it did, use the orc entry

an entry configured in HW that doesn't show in neigh_lookup()
driver logs an error message.
This introduces a race when removing multiple neighbors -
it's possible that a given entry would still be configured in HW
as its removal is still being processed but is already removed
from the kernel's neighbor tables.
Simply remove the error message and gracefully accept such events.
