o minor irrelevant fixes for uncommon error paths and fix several typos
o use LOG_INFO for connection logging, use LOG_NOTICE for other information
o minor error handling updates
|
|
o rename `persistent' mode to `alarm'
o rename `nack' mode to `ftfw'
o Now default synchronization mode is ftfw instead of alarm
|
|
feature is particularly useful for active-active setup without connection persistency, ie. you cannot know which firewall would filter a packet that belongs to a connection.

- use buffer of MTU size
conntrack:
- better protocol argument checkings
- fix per-protocol filtering, eg. conntrack -[L|E] -p tcp now works
- show per-protocol help, ie. conntrack -h -p tcp
- add alias --src for --orig-src and alias --dst for --orig-dst

- add len field to nethdr
- implement buffered send/recv to batch messages
- stop using netlink format for network messages: use similar TLV-based format
- reduce synchronization messages size up to 60%
- introduce periodic alive messages for sync-nack protocol
- timeslice alarm implementation: remove alarm pthread, remove locking
- simplify debugging functions: use nfct_snprintf instead
- remove major use of libnfnetlink functions: use libnetfilter_conntrack API
- deprecate conntrackd -F, use conntrack -F instead
- major rework of the network infrastructure: much simple, less messy

- remove several debug calls
- create a child to dispatch dump requests: this will help to simplify the
current locking schema. Later.

o remove reminiscents of delay destroy message and relax transitions
o remove confusing StripNAT parameter: NAT support enabled by default
o relax event tracking: *_update callbacks use cache_update_force
o use wraparound-aware functions after/before/between
o lots of cleanups

- empty debug_ct function if DEBUG_CT is not set
- revisit overrun handler: this is a hard battle, just try to do our best here, call Patrick :)
- explicit warning message when netlink_buffer_max_growth is reached
- fix silly bug in stats-mode when dumping in XML format
- fix UDP handler for conntrack
|
|
- flush nack queue in the conntrackd -f path
- do not increase add_fail counter for EEXIST errors
- cleanup sync-nack code
- improve mcast_recv_netmsg: sanity check before checksumming!
