* Removes KERNEL_64_USERSPACE_32Yasuyuki KOZAKAI2007-06-301-16/+0
| | | | | | | The recent kernel has compat layer for iptables. It doesn't have compat layer for libipq and ip6tables, but ip6tables with KERNEL_64_USERSPACE_32 is still broken. We should fix kernel instead of fixing them if and when we want use their 32bit binary with 64bit kernel.
* iptables -Z clears the per-rule counters, but not the chain policy counters ↵Andy Gay2006-08-221-0/+3

* BUG: libiptc chain references bug (Jesper Brouer <hawk@diku.dk>)Patrick McHardyJesper Brouer2006-07-251-0/+8
| | | | | | | | | Correcting a chain references increment bug in libiptc. The bug lies in function iptc_delete_entry() / TC_DELETE_ENTRY. The problem is the construction of "r" the rule entry, that is used for comparison. The problem is that the function iptcc_map_target() increase the target chains references count.
* libiptc symbols clash (Phil Oester <kernel@linuxace.com>)Phil Oester2006-07-052-0/+4
| | | | | As reported by Dmitry Levin, the TC_NUM_RULES and TC_GET_RULE exports clash. His patch below, resolving bug #456
* Don't overwrite errno with return value of setsockopt (which is -1 on error).Patrick McHardy2006-04-221-6/+2

* Revert the recent addition of memset()'s to TC_COMMIT. One of them is bogus ↵Phil Oester2005-02-041-3/+0
| | | | | | and the other one needs more investigation to why valgrind is complaining. Noticed and reverted by Phil Oester.
* re-implement alphabetic sorting to not confuse users who upgrade to 1.3.0Harald Welte2005-02-011-7/+18

* - Sets the 'iptc_fn' global variable to the pointer to the current functions ↵Derrik Pates2005-02-011-13/+36
| | | | | | | | in all major TC_* functions. This is necessary because in certain cases, an error return from a function that doesn't set 'iptc_fn' will conflict with a function-specific error return from one that does, causing TC_STRERROR() to return the wrong error string. This ensures that the right one will be returned. - Implements a simple reference counter for the netlink socket global variable 'sockfd'; this is necessary for IPTables::IPv4, where multiple tables (filter, nat, mangle, untracked) may be opened at one time. The way libiptc does it in the official version causes previously-opened tables to break such that attempts to commit changes will fail. - Adds a couple of memset() invocations in TC_COMMIT, based on past analysis with valgrind. It claimed that allocated structure were not being fully initialized, and adding the memset()s corrected this warning. (Derrik Pates <demon@devrandom.net>)
* Extension revision number support (if kernel supports the getsockopts).Rusty Russell2005-01-031-2/+2
| | | | | Enhance MARK match with second revision. Committed in anticipation of the kernel patch being applied.
* Stupid typo that meant we didn't compare target data when doing ↵Rusty Russell2004-12-291-1/+1
| | | | delete-by-matching-rule (found by nfsim test).
* Implement some optimization for finding rules to replace in TC_REPLACE_ENTRY.Martin Josefsson2004-12-181-2/+9
| | | | Stolen from TC_DELETE_NUM_ENTRY.
* Make "is_same" test basics and entries only: targets are generic.Rusty Russell2004-12-163-70/+72
| | | | | | | Make target testing aware of different kinds of rules. Change reverse logic: target_different now target_same. Set type to MODULE in iptcc_map_target. Add testcase for this.
* Remove GET_TARGET() define: this was for compiling iptables for debugging ↵Rusty Russell2004-12-161-37/+25
| | | | | | | (ie. without -O) on old kernels where ipt_get_target() was defined "extern inline". These days it's "static inline", and only developers build without -O anyway. Fix up DUMP_ENTRIES a little, but remove calls: it only dumps the table as loaded, not the changed (cached) table, which is misleading. Fix TC_DELETE_ENTRY: we need to use iptcc_map_target() before comparing, otherwise "-j DROP" (as an example) doesn't work.
* Search backwards when inserting/deleting in/from the top half of the rules ↵Martin Josefsson2004-10-241-12/+24

* Replace O(n) with O(1) when TC_INSERT_ENTRY() inserts an entry at the end.Martin Josefsson2004-09-231-8/+23
| | | | | | | | | | | | | | Do the same with TC_DELETE_NUM_ENTRY() when deleting the last rule. My rule management script does both of these things in certain situations. Created a file with 50.000 rules which my script converted into iptables-restore format but inserting each rule with an index instead of appending like the iptables-save output does. That took a while without this optimization. Same thing when deleting the 45.000 last rules in that chain, the script outputs deletes by number starting from the bottom. Inserting or deleting (by number) in the middle of the chain is still O(n) where n is the rulenumber where the insert/delete is taking place.
* Spelling error.Martin Josefsson2004-09-231-2/+2
|
* Fix returnvalue of TC_BUILTIN()Martin Josefsson2004-09-231-2/+2
| | | | | All jumps to nonexisting chains were believed to be jumps to builtin chains, that's bad as it made it impossible to add rules with external targets.
* Make sure to zero all the memory we allocate for the new table.Martin Josefsson2004-09-221-2/+2
| | | | | Makes flushing of chains containing more than a few entries work without potentially oopsing the kernel.
* Make TC_DELETE_ENTRY() and TC_DELETE_NUM_ENTRY() actually do something practicalMartin Josefsson2004-09-221-1/+5

* Insertion of rules with -I was broken.Martin Josefsson2004-09-221-5/+15
| | | | | | | It checked if a rule existed on the position we were inserting to. Thus inserting into an empty chain didn't work. And it didn't care about the fact that the first rule in the chain has index 1 the rulenumer we get starts at 0...

* implement chain cache ussing relative offsets instead of absolute entryHarald Welte2003-06-231-50/+73
| | | | | | pointers. This is needed for my current libiptc optimization work, since it needs the chain cache to still be correct after it has been reallocated to a different address.
