[Bug 1722] New: Rule delete with open interval does not work
https://bugzilla.netfilter.org/show_bug.cgi?id=1722
Bug ID: 1722
Summary: Rule delete with open interval does not work
Product: ebtables
Version: unspecified
Hardware: x86_64
OS: All
Status: NEW
Severity: enhancement
Priority: P5
Component: ebtables-nft
Assignee: pablo at netfilter.org
Reporter: phil at nwl.cc
One of the many ebtables oddities:
| ebtables -D FORWARD 3:
is supposed to delete the third and all following rules in FORWARD chain.
delete_entry() in xtables-eb.c is not aware of this, though. In practice, the
code will only add a single rule delete command to the list, namely for the
start interval one.
Simple reproducer:
| ebtables -A FORWARD -j RETURN
| ebtables -A FORWARD -j RETURN
| ebtables -A FORWARD -j RETURN
| ebtables -D FORWARD 2:
| [[ $(ebtables -L FORWARD | grep -c RETURN) -eq 1 ]] || echo "fail"
