Hi Pawel,
To clarify is that Dave Miller's tree or Linus's that you are talking
about? If it is Dave's tree how long ago was it you pulled it since I
think the fix was just pushed by Jeff Kirsher a few days ago.
The issue should be fixed in the following commit:
https://git.kernel.org/pub/scm/linux/kernel/git/davem/net.git/commit/drivers/net/ethernet/intel/i40e/i40e_txrx.c?id=2b9478ffc550f17c6cd8c69057234e91150f5972
Do you know when it is going to be available on net-next and linux-stable
repos?
Cheers,
Pavlos
I will make some tests today night with "net" git tree where this patch is
included.
Starting from 0:00 CET
:)
Upgraded and looks like problem is not solved with that patch
Currently running system with
https://git.kernel.org/pub/scm/linux/kernel/git/davem/net.git/
kernel
Still about 0.5GB of memory is leaking somewhere
Also can confirm that the latest kernel where memory is not leaking (with
use i40e driver intel 710 cards) is 4.11.12
With kernel 4.11.12 - after hour no change in memory usage.
also checked that with ixgbe instead of i40e with same net.git kernel there
is no memleak - after hour same memory usage - so for 100% this is i40e
driver problem.
So how long was the run to get the .5GB of memory leaking?
1 hour
Also is there any chance of you being able to bisect to determine
where the memory leak was introduced since as you pointed out it
didn't exist in 4.11.12 so odds are it was introduced somewhere
between 4.11 and the latest kernel release.
Can be hard cause currently need to back to 4.11.12 - this is production
host/router
Will try to find some free/test router for tests/bicects with i40e
driver (intel 710 cards)
Thanks.
