In 'net' we added a READ_ONCE() to the socket cached RX route read, whilst in 'net-next' Eric Dumazet touched the surrounding code dealing with how mini sockets are handled. With USB, it's a case of the same bug fix first going into net-next and then I cherry picked it back into net. Signed-off-by: David S. Miller <davem@davemloft.net>

2015-03-31sunrpc: make debugfs file creation failure non-fatalJeff Layton1-9/+9
We currently have a problem that SELinux policy is being enforced when creating debugfs files. If a debugfs file is created as a side effect of doing some syscall, then that creation can fail if the SELinux policy for that process prevents it. This seems wrong. We don't do that for files under /proc, for instance, so Bruce has proposed a patch to fix that. While discussing that patch however, Greg K.H. stated: "No kernel code should care / fail if a debugfs function fails, so please fix up the sunrpc code first." This patch converts all of the sunrpc debugfs setup code to be void return functins, and the callers to not look for errors from those functions. This should allow rpc_clnt and rpc_xprt creation to work, even if the kernel fails to create debugfs files for some reason. Symptoms were failing krb5 mounts on systems using gss-proxy and selinux.

2015-03-29usbnet: Fix tx_bytes statistic running backward in cdc_ncmBen Hutchings1-2/+4
cdc_ncm disagrees with usbnet about how much framing overhead should be counted in the tx_bytes statistics, and tries 'fix' this by decrementing tx_bytes on the transmit path. But statistics must never be decremented except due to roll-over; this will thoroughly confuse user-space. Also, tx_bytes is only incremented by usbnet in the completion path. Fix this by requiring drivers that set FLAG_MULTI_FRAME to set a tx_bytes delta along with the tx_packets count.

Currently the usbnet core does not update the tx_packets statistic for drivers with FLAG_MULTI_PACKET and there is no hook in the TX completion path where they could do this. cdc_ncm and dependent drivers are bumping tx_packets stat on the transmit path while asix and sr9800 aren't updating it at all. Add a packet count in struct skb_data so these drivers can fill it in, initialise it to 1 for other drivers, and add the packet count to the tx_packets statistic on completion.

2015-03-26mm: numa: slow PTE scan rate if migration failures occurMel Gorman1-4/+5
Dave Chinner reported the following on https://lkml.org/lkml/2015/3/1/226 Across the board the 4.0-rc1 numbers are much slower, and the degradation is far worse when using the large memory footprint configs. Perf points straight at the cause - this is from 4.0-rc1 on the "-o bhash=101073" config: - 56.07% 56.07% [kernel] [k] default_send_IPI_mask_sequence_phys - default_send_IPI_mask_sequence_phys - 99.99% physflat_send_IPI_mask - 99.37% native_send_call_func_ipi smp_call_function_many - native_flush_tlb_others - 99.85% flush_tlb_page ptep_clear_flush try_to_unmap_one rmap_walk try_to_unmap migrate_pages migrate_misplaced_page - handle_mm_fault - 99.73% __do_page_fault trace_do_page_fault do_async_page_fault + async_page_fault 0.63% native_send_call_func_single_ipi generic_exec_single smp_call_function_single This is showing excessive migration activity even though excessive migrations are meant to get throttled. Normally, the scan rate is tuned on a per-task basis depending on the locality of faults. However, if migrations fail for any reason then the PTE scanner may scan faster if the faults continue to be remote. This means there is higher system CPU overhead and fault trapping at exactly the time we know that migrations cannot happen. This patch tracks when migration failures occur and slows the PTE scanner.

This patch reintroduces immediate rehash during insertion. If we find during insertion that the table is full or the chain length exceeds a set limit (currently 16 but may be disabled with insecure_elasticity) then we will force an immediate rehash.

This patch adds the missing bits to allow multiple rehashes. The read-side as well as remove already handle this correctly. So it's only the rehasher and insertion that need modification to handle this. Note that this patch doesn't actually enable it so for now rehashing is still only performed by the worker thread. This patch also disables the explicit expand/shrink interface because the table is meant to expand and shrink automatically, and continuing to export these interfaces unnecessarily complicates the life of the rehasher since the rehash process is now composed of two parts.

2015-03-23inet: remove sk_listener parameter from syn_ack_timeout()Eric Dumazet1-1/+1
It is not needed, and req->sk_listener points to the listener anyway. request_sock argument can be const. Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2015-03-22netfilter: bridge: kill nf_bridge_padFlorian Westphal1-22/+0
The br_netfilter frag output function calls skb_cow_head() so in case it needs a larger headroom to e.g. re-add a previously stripped PPPOE or VLAN header things will still work (at cost of reallocation). We can then move nf_bridge_encap_header_len to br_netfilter. Signed-off-by: Florian Westphal <fw@strlen.de> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

2015-03-21Revert "selinux: add a skb_owned_by() hook"Eric Dumazet1-8/+0
This reverts commit ca10b9e9a8ca7342ee07065289cbe74ac128c169. No longer needed after commit eb8895debe1baba41fcb62c78a16f0c63c21662a ("tcp: tcp_make_synack() should use sock_wmalloc") When under SYNFLOOD, we build lot of SYNACK and hit false sharing because of multiple modifications done on sk_listener->sk_wmem_alloc Since tcp_make_synack() uses sock_wmalloc(), there is no need to call skb_set_owner_w() again, as this adds two atomic operations.

Conflicts: drivers/net/ethernet/emulex/benet/be_main.c net/core/sysctl_net_core.c net/ipv4/inet_diag.c The be_main.c conflict resolution was really tricky. The conflict hunks generated by GIT were very unhelpful, to say the least. It split functions in half and moved them around, when the real actual conflict only existed solely inside of one function, that being be_map_pci_bars(). So instead, to resolve this, I checked out be_main.c from the top of net-next, then I applied the be_main.c changes from 'net' since the last time I merged. And this worked beautifully. The inet_diag.c and sysctl_net_core.c conflicts were simple overlapping changes, and were easily to resolve. Signed-off-by: David S. Miller <davem@davemloft.net>
