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.
