2015-08-13Add a matching set of device_ functions for determining mac/phyJeremy Linton
OF has some helper functions for parsing MAC and PHY settings. In cases where the platform is providing this information rather than the device itself, there needs to be similar functions for ACPI. These functions are slightly modified versions of the ones in of_net which can use information provided via DT or ACPI. Signed-off-by: Jeremy Linton <jeremy.linton@arm.com> Signed-off-by: David S.

Yuchung Cheng says: ==================== minor tail loss probe improvements This patch series enhance the tail loss probe (TLP) on some error conditions. When TLP fails to send a probe, it will no longer extend the RTO.

2015-08-13tcp: don't extend RTO on failed loss probe attemptsYuchung Cheng
If TLP was unable to send a probe, it extended the RTO to now + icsk_rto. But extending the RTO makes little sense if no TLP probe went out. With this commit, instead of extending the RTO we re-arm it relative to the transmit time of the write queue head.

Mugunthan V N says: ==================== Add AM335x PG1.0 CPSW errata workaround With commit 870915feabdc ("drivers: net: cpsw: remove disable_irq/enable_irq as irq can be masked from cpsw itself"), CPSW on AM335x beagle bone white is broken as there is a errata for AM335x PG1.0.

2015-08-13drivers: net: cpsw: add am335x errata workarround for interrutpsMugunthan V N
As per Am335x Errata [1] Advisory 1.0.9, The CPSW C0_TX_PEND and C0_RX_PEND interrupt outputs provide a single transmit interrupt that combines transmit channel interrupts TXPEND[7:0] and a single receive interrupt that combines receive channel interrupts RXPEND[7:0]. The TXPEND[0] and RXPEND[0] interrupt outputs are connected to the ARM Cortex-A8 interrupt controller (INTC) rather than the C0_TX_PEND and C0_RX_PEND interrupt outputs. So even though CPSW interrupt is cleared by writing appropriate values to EOI register the interrupt is not cleared in IRQ controller. So interrupt is still pending and CPU is struck in ISR, the workaround is to disable the interrupts in ARM irq controller.

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.

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).

2015-08-12dm cache policy smq: move 'dm-cache-default' module alias to SMQYi Zhang
When creating dm-cache with the default policy, it will call request_module("dm-cache-default") to register the default policy. But the "dm-cache-default" alias was left referring to the MQ policy. Fix this by moving the module alias to SMQ.

2015-08-12dm btree: add ref counting ops for the leaves of top level btreesJoe Thornber
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.

The reason for this was because streamline-config.pl only looks at Makefiles, and not Kbuild files. As these modules use Kbuild for their names, they too need to be checked by localmodconfig. This was fixed by Richard Weinberger" * tag 'localmodconfig-v4.2-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-kconfig: localmodconfig: Use Kbuild files too
2015-08-11localmodconfig: Use Kbuild files tooRichard Weinberger
In kbuild it is allowed to define objects in files named "Makefile" and "Kbuild". Currently localmodconfig reads objects only from "Makefile"s and misses modules like nouveau.
