Consider the following scenario:

.ndo_bpf()		| ice_prepare_for_reset()		|
________________________|_______________________________________|
rtnl_lock()		|					|
ice_down()		|					|
			| test_bit(ICE_VSI_DOWN) - true		|
			| ice_dis_vsi() returns			|
ice_up()		|					|
			| proceeds to rebuild a running VSI	|

.ndo_bpf() is not the only rtnl-locked callback that toggles the interface
to apply new configuration. Another example is .set_channels().

To avoid the race condition above, act only after reading ICE_VSI_DOWN
under rtnl_lock.

Fixes: 0f9d5027a749 ("ice: Refactor VSI allocation, deletion and rebuild flow")

ehh sorry for being sloppy reviewer. we still are testing ICE_VSI_DOWN in
ice_vsi_close(). wouldn't all of this be cleaner if we would bail out of
the called function when bit was already set?

I am not sure I see the possibility to rewrite this as you suggest, we cannot 
bail out for the netif_running() case due to needing to unlock after 
ice_vsi_close() finishes. This leaves bailing out in case of CTRL VSI and 
non-running PF, which we could do, but it would require a lengthy if condition, 
which is not that much better than nested code, IMO.

Hmm. I meant to move bit checking onto ice_vsi_close() only, so you would
bail out of it in case bit has already been set.

overall, ice_dis_vsi() is a very cumbersome way of calling ice_vsi_close()
:(

I guess we can progress with what you have but i'd like to brainstorm
later about some simplification around it.

I prototyped something but not tested that, just to maybe spark a
discussion. Feels easier to read and swallow in the end. Not sure if
functionality is kept:)

Ok, now I get it.
Yes, this is something worth considering for a -next patch. Opting out of 
closing the VSI based on a down state seems not very nice though :/
I am not even sure if such approach is correct in ice_dis_vsi or is it just 
some ancient atrifact.
Seems like it needs some VSI state changes analysis.
