* libiptc: use a family-invariant xtc_ops struct for code reductionJan Engelhardt2011-09-111-0/+1

* src: resolve old macro names that are indirectionsJan Engelhardt2011-09-111-15/+15
| | | | | | | | | | | Command used: git grep -f <(pcregrep -hior '(?<=#define\s)IP6?(T_\w+)(?=\s+X\1)' include/) and then fix all occurrences. Signed-off-by: Jan Engelhardt <jengelh@medozas.de>
* libiptc: combine common types: _handleJan Engelhardt2011-09-111-4/+1
| | | | | | | No real API/ABI change incurred, since the definition of the structs' types is not visible anyhow. Signed-off-by: Jan Engelhardt <jengelh@medozas.de>

* iptables: add -C to check for existing rulesStefan Tomanek2011-03-081-0/+1
| | | | | | | | | | | | | | | | | It is often useful to check whether a specific rule is already present in a chain without actually modifying the iptables config. Services like fail2ban usually employ techniques like grepping through the output of "iptables -L" which is quite error prone. This patch adds a new operation -C to the iptables command which mostly works like -D; it can detect and indicate the existence of the specified rule by modifying the exit code. The new operation TC_CHECK_ENTRY uses the same code as the -D operation, whose functions got a dry-run parameter appended.

* libiptc: remove typedef indirectionJan Engelhardt2008-11-101-3/+3
| | | | | | | | | | | Don't you hate it when iptc_handle_t *x actually is a double-indirection struct iptc_handle **? This also shows the broken constness model, since "const iptc_handle_t x" = "iptc_handle_t const x" = "struct iptc_handle *const x", which is like no const at all. Lots of things to do then.
