This is an automated email from the git hooks/post-receive script. It was
generated because a ref change was pushed to the repository containing
the project "conntrack-tools".
The branch, vyatta/expect has been updated
discards 694c19f8f77438a478beeb9fa1bc79f488ae0436 (commit)
via cb4f58ded0eb5338c242d646dbbe0e2f79599171 (commit)
This update added new revisions after undoing existing revisions. That is
to say, the old revision is not a strict subset of the new revision. This
situation occurs when you --force push a change and generate a repository
containing something like this:
* -- * -- B -- O -- O -- O (694c19f8f77438a478beeb9fa1bc79f488ae0436)
\
N -- N -- N (cb4f58ded0eb5338c242d646dbbe0e2f79599171)
When this happens we assume that you've already had alert emails for all
of the O revisions, and so we here report only the revisions in the N
branch from the common base, B.
Those revisions listed above that are new to this repository have
not appeared on any other notification email; so we list those
revisions in full, below.

conntrackd: initial support for expectations (incomplete!)
This patch adds initial support to synchronize expectations.
Note that *it is imcomplete*. Currently, it only adds and
deletes the expectation in the internal cache:
(term-1)$ sudo modprobe nf_conntrack_ftp
(term-1)$ nc ftp.debian.org 21
USER anonymous
PASS
PASV
(Now switch to term-2)
(term-2)# conntrackd -i exp
300 proto=6 src=192.168.1.137 dst=130.89.149.226 sport=0 dport=52712 [active since 55s]
You have to enable the expectation support in the configuration
file with the following option:
Sync {
...
Options {
ExpectationSync On
}
}
Still needs to be implemented:
- Initial dump of the expect table.
- The object to message build/parse functions.
- The direct injection.
- Commit operation.
- Flush operation.
- User-space filtering.
Among others.
You'll have to get a fresh working copy of libnetfilter_conntrack,
otherwise you'll hit one assertion in nfct_cmp().
