Hello,
This patchset contains accumulated fixes for the nf tree:
1-3) Fixes for the recently added resizable hash tables (v5)
4) dest from trash can be leaked if ip_vs_start_estimator() fails
5) fixed races and locking for the estimation kthreads (v5)
6) fix for wrong roundup_pow_of_two() usage in the resizable hash
tables
7-8) v2 of the changes from Waiman Long to properly guard against
the housekeeping_cpumask() updates:
https://lore.kernel.org/netfilter-devel/20260331165015.2777765-1-longman@xxxxxxxxxx/
I added missing Fixes tag. The original description:
Since commit 041ee6f3727a ("kthread: Rely on HK_TYPE_DOMAIN for preferred
affinity management"), the HK_TYPE_KTHREAD housekeeping cpumask may no
longer be correct in showing the actual CPU affinity of kthreads that
have no predefined CPU affinity. As the ipvs networking code is still
using HK_TYPE_KTHREAD, we need to make HK_TYPE_KTHREAD reflect the
reality.
This patch series makes HK_TYPE_KTHREAD an alias of HK_TYPE_DOMAIN
and uses RCU to protect access to the HK_TYPE_KTHREAD housekeeping
cpumask.
v3:
* Apply to recent nf tree. Changing the conn limit of 2^31 is
still a work to do for boxes with 640GB+ memory (ipvs conn
size is ~300 bytes on 64-bit)
v2:
* Reports: https://sashiko.dev/#/patchset/20260428175725.72050-1-ja%40ssi.bg
* introduce new patch at position 4 (dest leak)
* patch 6: check for n > 0 before roundup_pow_of_two
* patch 7 and 8 are now in reverse order to help bisection
