Regression tests for the shared-block NULL derefs fixed in the previous
two patches:

  - fw: attempt to attach an empty fw filter to a shared block and
    verify the configuration is rejected with EINVAL.
  - flow: create a flow filter on a shared block without a baseclass
    and verify the configuration is rejected with EINVAL.

selftests/tc-testing: add test for HFSC divide-by-zero in rtsc_min() 2026-03-28T03:41:11+00:00 Xiang Mei xmei5@asu.edu 2026-03-26T20:43:10+00:00 5d17af9eb2dd3de6846ed344c883de7812e6cc09 Add a regression test for the divide-by-zero in rtsc_min() triggered when m2sm() converts a large m1 value (e.g. 32gbit) to a u64 scaled slope reaching 2^32. rtsc_min() stores the difference of two such u64 values (sm1 - sm2) in a u32 variable `dsm`, truncating 2^32 to zero and causing a divide-by-zero oops in the concave-curve intersection path. The test configures an HFSC class with m1=32gbit d=1ms m2=0bit, sends a packet to activate the class, waits for it to drain and go idle, then sends another packet to trigger reactivation through rtsc_min().
