2015-08-12net: ipv4: increase dhcp inter device timeoutMugunthan V N
When a system has multiple ethernet devices and during DHCP request (for using NFS), the system waits only for HZ/2 which is 500mS before switching to another interface for DHCP. There are some routers (Ex: Trendnet routers) which responds to DHCP request at about 560mS. When the system has only one ethernet interface there is no issue as the timeout is 2S and the dev xid doesn't changes and only retries. But when the system has multiple Ethernet like DRA74x with CPSW in dual EMAC mode, the DHCP response is dropped as the dev xid changes while shifting to the next device. So changing inter device timeout to HZ (which is 1S). Signed-off-by: Mugunthan V N <mugunthanvnm@ti.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2015-08-12gianfar: remove faulty filer optimizerJakub Kicinski
Current filer rule optimization is broken in several ways: (1) Can perform reads/writes beyond end of allocated tables. (gianfar_ethtool.c:1326). (2) It breaks badly for rules with more than 2 specifiers (e.g. matching ip, port, tos). Example: # ethtool -N eth2 flow-type udp4 dst-ip 10.0.0.1 dst-port 1 tos 1 action 1 Added rule with ID 254 # ethtool -N eth2 flow-type udp4 dst-ip 10.0.0.2 dst-port 2 tos 2 action 9 Added rule with ID 253 # ethtool -N eth2 flow-type udp4 dst-ip 10.0.0.3 dst-port 3 tos 3 action 17 Added rule with ID 252 # ./filer_decode /sys/kernel/debug/gfar1/filer_raw 00: MASK == 00000210 AND Q:00 ctrl:00000080 prop:00000210 01: FPR == 00000210 AND CLE Q:00 ctrl:00000281 prop:00000210 02: MASK == ffffffff AND Q:00 ctrl:00000080 prop:ffffffff 03: DPT == 00000003 AND Q:00 ctrl:0000008e prop:00000003 04: TOS == 00000003 AND Q:00 ctrl:0000008a prop:00000003 05: DIA == 0a000003 AND Q:11 ctrl:0000448c prop:0a000003 06: DPT == 00000002 AND Q:00 ctrl:0000008e prop:00000002 07: TOS == 00000002 AND Q:00 ctrl:0000008a prop:00000002 08: DIA == 0a000002 AND Q:09 ctrl:0000248c prop:0a000002 09: DIA == 0a000001 AND Q:00 ctrl:0000008c prop:0a000001 0a: DPT == 00000001 AND Q:00 ctrl:0000008e prop:00000001 0b: TOS == 00000001 CLE Q:01 ctrl:0000060a prop:00000001 ff: MASK >= 00000000 Q:00 ctrl:00000020 prop:00000000 (Entire cluster gets AND-ed together). (3) We observed that the masking rules it generates do not play well with clustering on P2020. Only first rule of the cluster would ever fire. Given that optimizer relies heavily on masking this is very hard to fix. Example: # ethtool -N eth2 flow-type udp4 dst-ip 10.0.0.1 dst-port 1 action 1 Added rule with ID 254 # ethtool -N eth2 flow-type udp4 dst-ip 10.0.0.2 dst-port 2 action 9 Added rule with ID 253 # ethtool -N eth2 flow-type udp4 dst-ip 10.0.0.3 dst-port 3 action 17 Added rule with ID 252 # ./filer_decode /sys/kernel/debug/gfar1/filer_raw 00: MASK == 00000210 AND Q:00 ctrl:00000080 prop:00000210 01: FPR == 00000210 AND CLE Q:00 ctrl:00000281 prop:00000210 02: MASK == ffffffff AND Q:00 ctrl:00000080 prop:ffffffff 03: DPT == 00000003 AND Q:00 ctrl:0000008e prop:00000003 04: DIA == 0a000003 Q:11 ctrl:0000440c prop:0a000003 05: DPT == 00000002 AND Q:00 ctrl:0000008e prop:00000002 06: DIA == 0a000002 Q:09 ctrl:0000240c prop:0a000002 07: DIA == 0a000001 AND Q:00 ctrl:0000008c prop:0a000001 08: DPT == 00000001 CLE Q:01 ctrl:0000060e prop:00000001 ff: MASK >= 00000000 Q:00 ctrl:00000020 prop:00000000 Which looks correct according to the spec but only the first (eth id 252)/last added rule for 10.0.0.3 will ever trigger. As if filer did not treat the AND CLE as cluster start but also kept AND-ing the rules. We found no errata covering this. The fact that nobody noticed (2) or (3) makes me think that this feature is not very widely used and we should just remove it.

This enables the use of ethtool --set-channels devname combined N to change the number of vRSS queues. Separate rx, tx, and other parameters are not supported. The maximum is rsscap.num_recv_que. It passes the given value to rndis_filter_device_add through the device_info->num_chn field. If the procedure fails, it attempts to recover to the prior state. If the recovery fails, it logs an error and aborts. Current num_chn is saved and restored when changing the MTU.

2015-08-12bonding: Gratuitous ARP gets dropped when first slave addedVenkat Venkatsubra
When the first slave is added (such as during bootup) the first gratuitous ARP gets dropped. We don't see this drop during a failover. The packet gets dropped in qdisc (noop_enqueue). The fix is to delay the sending of gratuitous ARPs till the bond dev's carrier is present. It can also be worked around by setting num_grat_arp to more than 1.

When using nested btrees, the top leaves of the top levels contain block addresses for the root of the next tree down. If we shadow a shared leaf node the leaf values (sub tree roots) should be incremented accordingly. This is only an issue if there is metadata sharing in the top levels. Which only occurs if metadata snapshots are being used (as is possible with dm-thinp). And could result in a block from the thinp metadata snap being reused early, thus corrupting the thinp metadata snap.

2015-08-11bpf: s390: Fix build error caused by the struct bpf_array member name changedKaixu Xia
There is a build error that "'struct bpf_array' has no member named 'prog'" on s390. In commit 2a36f0b92eb6 ("bpf: Make the bpf_prog_array_map more generic"), the member 'prog' of struct bpf_array is replaced by 'ptrs'. So this patch fixes it.

David Daney says: ==================== net: thunder: Add ACPI support. Change from v1: Drop PHY binding part, use fwnode_property* APIs. The first patch (1/2) rearranges the existing code a little with no functional change to get ready for the second. The second (2/2) does the actual work of adding support to extract the needed information from the ACPI tables. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
2015-08-11net, thunder, bgx: Add support to get MAC address from ACPI.David Daney
Currently there is no way to get the MAC address in a firmware independent manner, so set the MAC address of the device directly from the ACPI tables. The binding agrees with the proposed standard here: http://www.uefi.org/sites/default/files/resources/nic-request-v2.pdf Based on code from: Narinder Dhillon <ndhillon@cavium.com> Tomasz Nowicki <tomasz.nowicki@linaro.org> Robert Richter <rrichter@cavium.com> Signed-off-by: Tomasz Nowicki <tomasz.nowicki@linaro.org> Signed-off-by: Robert Richter <rrichter@cavium.com> Signed-off-by: David Daney <david.daney@cavium.com> Signed-off-by: David S.

2015-08-11xen/xenbus: Don't leak memory when unmapping the ring on HVM backendJulien Grall
The commit ccc9d90a9a8b5c4ad7e9708ec41f75ff9e98d61d "xenbus_client: Extend interface to support multi-page ring" removes the call to free_xenballooned_pages() in xenbus_unmap_ring_vfree_hvm(), leaking a page for every shared ring. Only with backends running in HVM domains were affected.

2015-08-10inet: fix possible request socket leakEric Dumazet
In commit b357a364c57c9 ("inet: fix possible panic in reqsk_queue_unlink()"), I missed fact that tcp_check_req() can return the listener socket in one case, and that we must release the request socket refcount or we leak it. Tested: Following packetdrill test template shows the issue 0 socket(..., SOCK_STREAM, IPPROTO_TCP) = 3 +0 setsockopt(3, SOL_SOCKET, SO_REUSEADDR, [1], 4) = 0 +0 bind(3, ..., ...) = 0 +0 listen(3, 1) = 0 +0 < S 0:0(0) win 2920 <mss 1460,sackOK,nop,nop> +0 > S. 0:0(0) ack 1 <mss 1460,nop,nop,sackOK> +.002 < . 1:1(0) ack 21 win 2920 +0 > R 21:21(0) Fixes: b357a364c57c9 ("inet: fix possible panic in reqsk_queue_unlink()") Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S.

2015-08-10inet: fix races with reqsk timersEric Dumazet
reqsk_queue_destroy() and reqsk_queue_unlink() should use del_timer_sync() instead of del_timer() before calling reqsk_put(), otherwise we could free a req still used by another cpu. But before doing so, reqsk_queue_destroy() must release syn_wait_lock spinlock or risk a dead lock, as reqsk_timer_handler() might need to take this same spinlock from reqsk_queue_unlink() (called from inet_csk_reqsk_queue_drop()) Fixes: fa76ce7328b2 ("inet: get rid of central tcp/dccp listener timer") Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S.
