We've run into this problem.  The patch that's been committed to HEAD fixes the bug.

Would someone MFC it, please?  This bug has been present in 12.0-RELEASE and 12.1-RELEASE; it'd be great to have it fixed before 12.2-RELEASE.

Thanks.

Assign to committer that resolved, and Cc: another committer that has been long active in this area.

While here, set mfc-stable12 flag.

Comment 5 Tassilo Philipp 2022-12-05 19:38:47 UTC

Not sure if I should've made a new PR, but since this one is still open and does mention a change to pf_tree.def, I add it here. The problem I came across is that file cannot be used to read mappings from:

$ bsnmpwalk -i pf_tree.def  1.3.6.1.4.1.12325
bsnmpwalk: Error adding leaf pfInterfacesIfRefsState to list
bsnmpwalk: Failed to read mappings from file pf_tree.def

This is due to line 111 in the file:

   (5 pfInterfacesIfRefsState NULL GET)

bsnmp cannot handle the "NULL", I'm not sure what type it should be, but a test taking out that line makes at least the rest of the mappings work.
