====================
Netfilter/IPVS updates for net-next
The following patchset contains Netfilter/IPVS updates for net-next,
they are:
1) Count pre-established connections as active in "least connection"
schedulers such that pre-established connections to avoid overloading
backend servers on peak demands, from Michal Kubecek via Simon Horman.
2) Address a race condition when resizing the conntrack table by caching
the bucket size when fulling iterating over the hashtable in these
three possible scenarios: 1) dump via /proc/net/nf_conntrack,
2) unlinking userspace helper and 3) unlinking custom conntrack timeout.
From Liping Zhang.
3) Revisit early_drop() path to perform lockless traversal on conntrack
eviction under stress, use del_timer() as synchronization point to
avoid two CPUs evicting the same entry, from Florian Westphal.
4) Move NAT hlist_head to nf_conn object, this simplifies the existing
NAT extension and it doesn't increase size since recent patches to
align nf_conn, from Florian.
5) Use rhashtable for the by-source NAT hashtable, also from Florian.
6) Don't allow --physdev-is-out from OUTPUT chain, just like
--physdev-out is not either, from Hangbin Liu.
7) Automagically set on nf_conntrack counters if the user tries to
match ct bytes/packets from nftables, from Liping Zhang.
8) Remove possible_net_t fields in nf_tables set objects since we just
simply pass the net pointer to the backend set type implementations.
9) Fix possible off-by-one in h323, from Toby DiPasquale.
10) early_drop() may be called from ctnetlink patch, so we must hold
rcu read size lock from them too, this amends Florian's patch #3
coming in this batch, from Liping Zhang.
11) Use binary search to validate jump offset in x_tables, this
addresses the O(n!) validation that was introduced recently
resolve security issues with unpriviledge namespaces, from Florian.
12) Fix reference leak to connlabel in error path of nft_ct, from Zhang.
13) Three updates for nft_log: Fix log prefix leak in error path. Bail
out on loglevel larger than debug in nft_log and set on the new
NF_LOG_F_COPY_LEN flag when snaplen is specified. Again from Zhang.
14) Allow to filter rule dumps in nf_tables based on table and chain
names.
15) Simplify connlabel to always use 128 bits to store labels and
get rid of unused function in xt_connlabel, from Florian.
16) Replace set_expect_timeout() by mod_timer() from the h323 conntrack
helper, by Gao Feng.
17) Put back x_tables module reference in nft_compat on error, from
Liping Zhang.
18) Add a reference count to the x_tables extensions cache in
nft_compat, so we can remove them when unused and avoid a crash
if the extensions are rmmod, again from Zhang.

git://git.kernel.org/pub/scm/linux/kernel/git/gfs2/linux-gfs2
Pull gfs2 updates from Bob Peterson:
"We've got ten patches this time, half of which are related to a
plethora of nasty outcomes when inodes are transitioned from the
unlinked state to the free state. Small file systems are particularly
vulnerable to these problems, and it can manifest as mainly hangs, but
also file system corruption. The patches have been tested for
literally many weeks, with a very gruelling test, so I have a high
level of confidence.
- Andreas Gruenbacher wrote a series of five patches for various
lockups during the transition of inodes from unlinked to free.
The main patch is titled "Fix gfs2_lookup_by_inum lock inversion"
and the other four are support and cleanup patches related to that.
- Ben Marzinski contributed two patches with regard to a recreatable
problem when gfs2 tries to write a page to a file that is being
truncated, resulting in a BUG() in gfs2_remove_from_journal.
Note that Ben had to export vfs function __block_write_full_page to
get this to work properly. It's been posted a long time and he
talked to various VFS people about it, and nobody seemed to mind.
- I contributed 3 patches:
o The first one fixes a memory corruptor: a race in which one
process can overwrite the gl_object pointer set by another
process, causing kernel panic and other symptoms.
o The second patch fixes another race that resulted in a
false-positive BUG_ON. This occurred when resource group
reservations were freed by one process while another process
was trying to grab a new reservation in the same resource
group.
o The third patch fixes a problem with doing journal replay when
the journals are not all the same size"
* tag 'gfs2-4.7.fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/gfs2/linux-gfs2:
GFS2: Fix gfs2_replay_incr_blk for multiple journal sizes
