This patch adds run-time statistics that you can check via
`conntrackd -s runtime'. This information is useful for
trouble-shooting.
This patch replaces several log messages that can be triggered in
runtime. The idea behind this patch is to avoid log message flooding
under errors.

This patch fixes a race condition that triggers EILSEQ errors
(wrong sequence message). The problems is triggered when the child
process resets the timers at the same time that the parent process
requests a resync. Since both the child and the parent process use
the same descriptors, the sequence tracking code in libnfnetlink
gets confused as it considers that it is receiving out of sequence
netlink messages.
This patch introduces internal handlers to commit and reset timers
so that the parent and the child do not use the same descriptors
to operate with the kernel.
This patch changes the prototype of all nf_*_conntrack() functions.
Now, the nfct handler is passed as first parameter, this change is
required to fix this problem. The rest of the changes on the API
is done for consistency.

The current wait() error handling was insufficient. This patch
introduce more verbose error reporting.

This patch recovers the option -F for conntrackd. This will be
particularly useful to flush the kernel conntrack table without
getting the event notification of the conntrack deletions
(that will happen with Linux kernel >= 2.6.29).

This patch is a cleanup. It moves the callbacks from netlink.c to
run.c where they are actually invoked. This is better for code
readability as I usually have to switch from run.c to netlink.c
to remember what the callbacks actually do.

This patch fixes a segfault when conntrackd -k is invoked for an
instance of conntrackd with no use of the Filter clause.

This patch adds nl_get_conntrack and it changes the behaviour of
nl_exist_conntrack. Now, nl_get_conntrack requests the kernel for
a conntrack and updates the cached entry. On the other hand,
nl_exist_conntrack only inquiries for the existence of the
entry.

This patch reworks the user-space filtering. Although we have
kernel-space filtering since Linux kernel >= 2.6.26, we keep userspace
filtering to ensure backward compatibility. Moreover, this patch
prepares the implementation of the kernel-space filtering via
libnetfilter_conntrack's high-level berkeley socket filter API.

whitespace cleanups
|
|
|
|
added struct local_server, several cleanups in local socket infrastructure
This patch include minor changes by the comitter
|
|
fix error checking of local_create_server()
|
|
|
|
- Save initialization stage in the __run() loop
|
|
- Pass next_alarm to __run() only if there is an alarm
- Eliminate the "timeout" parameter
- the alarm functions get_next_alarm_run() and do_alarm_run() return an timeval pointer instead of a boolean
|
|
|
|
|
|
improve error message if netlink initialization fails
|
|
Simplify logging infrastructure
|
|
import only required C headers and put local headers on top to check
|
|
|
|
Fix tons of gcc warnings
|
|
add missing function prototypes

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
|

- 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.
|
|
- 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
