Subject: [PATCH 00/25] Netfilter/IPVS updates for net-next
Sorry, resending this pull request, I modified my robot and it was not
including explicit Cc to netdev.
-o-
Hi David,
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.
