The following batch contains Netfilter fixes for 3.8-rc1. They are
a mixture of old bugs that have passed unnoticed (I'll pass these to
stable) and more fresh ones from the previous merge window, they are:
* Fix for MAC address in 6in4 tunnels via NFLOG that results in ulogd
showing up wrong address, from Bob Hockney.
* Fix a comment in nf_conntrack_ipv6, from Florent Fourcot.
* Fix a leak an error path in ctnetlink while creating an expectation,
from Jesper Juhl.
* Fix missing ICMP time exceeded in the IPv6 defragmentation code, from
Haibo Xi.
* Fix inconsistent handling of routing changes in MASQUERADE for the
new connections case, from Andrew Collins.
* Fix a missing skb_reset_transport in ip[6]t_REJECT that leads to
crashes in the ixgbe driver (since it seems to access the transport
header with TSO enabled), from Mukund Jampala.
* Recover obsoleted NOTRACK target by including it into the CT and spot
a warning via printk about being obsoleted. Many people don't check the
scheduled to be removal file under Documentation, so we follow some
less agressive approach to kill this in a year or so. Spotted by Florian
Westphal, patch from myself.
* Fix race condition in xt_hashlimit that allows to create two or more
entries, from myself.
* Fix crash if the CT is used due to the recently added facilities to
consult the dying and unconfirmed conntrack lists, from myself.

In function find_fsync_dnodes() - the fsync inodes gets added to the list, but
in one path suppose f2fs_iget results in error, in such case - error gets added
to the fsync inode list.
In next call to recover_data()->get_fsync_inode()
entry = list_entry(this, struct fsync_inode_entry, list);
if (entry->inode->i_ino == ino)
This can result in "invalid access to memory" when it encounters 'error' as
entry in the fsync inode list.
So, add the fsync inode entry to the list only in case of no errors.

We should not set con->state to CLOSED here; that happens in

A number of assertions in the ceph messenger are implemented with
BUG_ON(), killing the system if connection's state doesn't match
what's expected. At this point our state model is (evidently) not
well understood enough for these assertions to trigger a BUG().
Convert all BUG_ON(con->state...) calls to be WARN_ON(con->state...)
so we learn about these issues without killing the machine.
We now recognize that a connection fault can occur due to a socket
closure at any time, regardless of the state of the connection. So
there is really nothing we can assert about the state of the
connection at that point so eliminate that assertion.

When ceph_osdc_handle_map() is called to process a new osd map,
kick_requests() is called to ensure all affected requests are
updated if necessary to reflect changes in the osd map. This
happens in two cases: whenever an incremental map update is
processed; and when a full map update (or the last one if there is
more than one) gets processed.
In the former case, the kick_requests() call is followed immediately
by a call to reset_changed_osds() to ensure any connections to osds
affected by the map change are reset. But for full map updates
this isn't done.
Both cases should be doing this osd reset.
Rather than duplicating the reset_changed_osds() call, move it into
the end of kick_requests().
Signed-off-by: Alex Elder <elder@inktank.com>
Reviewed-by: Sage Weil <sage@inktank.com>
The kick_requests() function is called by ceph_osdc_handle_map()
when an osd map change has been indicated. Its purpose is to
re-queue any request whose target osd is different from what it
was when it was originally sent.
It is structured as two loops, one for incomplete but registered
requests, and a second for handling completed linger requests.
As a special case, in the first loop if a request marked to linger
has not yet completed, it is moved from the request list to the
linger list. This is as a quick and dirty way to have the second
loop handle sending the request along with all the other linger
requests.
Because of the way it's done now, however, this quick and dirty
solution can result in these incomplete linger requests never
getting re-sent as desired. The problem lies in the fact that
the second loop only arranges for a linger request to be sent
if it appears its target osd has changed. This is the proper
handling for *completed* linger requests (it avoids issuing
the same linger request twice to the same osd).
But although the linger requests added to the list in the first loop
may have been sent, they have not yet completed, so they need to be
re-sent regardless of whether their target osd has changed.
The first required fix is we need to avoid calling __map_request()
on any incomplete linger request. Otherwise the subsequent
__map_request() call in the second loop will find the target osd
has not changed and will therefore not re-send the request.
Second, we need to be sure that a sent but incomplete linger request
gets re-sent. If the target osd is the same with the new osd map as
it was when the request was originally sent, this won't happen.
This can be fixed through careful handling when we move these
requests from the request list to the linger list, by unregistering
the request *before* it is registered as a linger request. This
works because a side-effect of unregistering the request is to make
the request's r_osd pointer be NULL, and *that* will ensure the
second loop actually re-sends the linger request.
Processing of such a request is done at that point, so continue with
the next one once it's been moved.
