-Subject: [PATCH] e1000e: Fix tight loop implementation of systime read
- algorithm
-
-Change the algorithm. Read systimel twice and check for overflow.
-If there was no overflow, use the first value.
-If there was an overflow, read systimeh again and use the second
-systimel value.

-Subject: [PATCH] netfilter: conntrack: use nf_ct_tmpl_free in CT/synproxy
- error paths
-
-Commit 0838aa7fcfcd ("netfilter: fix netns dependencies with conntrack
-templates") migrated templates to the new allocator api, but forgot to
-update error paths for them in CT and synproxy to use nf_ct_tmpl_free()
-instead of nf_conntrack_free().
-
-Due to that, memory is being freed into the wrong kmemcache, but also
-we drop the per net reference count of ct objects causing an imbalance.
-
-In Brad's case, this leads to a wrap-around of net->ct.count and thus
-lets __nf_conntrack_alloc() refuse to create a new ct object:
-
- [ 10.340913] xt_addrtype: ipv6 does not support BROADCAST matching
- [ 10.810168] nf_conntrack: table full, dropping packet
- [ 11.917416] r8169 0000:07:00.0 eth0: link up
- [ 11.917438] IPv6: ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready
- [ 12.815902] nf_conntrack: table full, dropping packet
- [ 15.688561] nf_conntrack: table full, dropping packet
- [ 15.689365] nf_conntrack: table full, dropping packet
- [ 15.690169] nf_conntrack: table full, dropping packet
- [ 15.690967] nf_conntrack: table full, dropping packet
- [...]
-
-With slab debugging, it also reports the wrong kmemcache (kmalloc-512 vs.
-nf_conntrack_ffffffff81ce75c0) and reports poison overwrites, etc. Thus,
-to fix the problem, export and use nf_ct_tmpl_free() instead.
