2018-07-18net: qca_spi: Make sure the QCA7000 reset is triggeredStefan Wahren
In case the SPI thread is not running, a simple reset of sync state won't fix the transmit timeout. We also need to wake up the kernel thread. Signed-off-by: Stefan Wahren <stefan.wahren@i2se.com> Fixes: ed7d42e24eff ("net: qca_spi: fix transmit queue timeout handling") Signed-off-by: David S. Miller <davem@davemloft.net>
2018-07-18net: qca_spi: Avoid packet drop during initial syncStefan Wahren
As long as the synchronization with the QCA7000 isn't finished, we cannot accept packets from the upper layers. So let the SPI thread enable the TX queue after sync and avoid unwanted packet drop.

2018-07-18ipv6: fix useless rol32 call on hashColin Ian King
The rol32 call is currently rotating hash but the rol'd value is being discarded. I believe the current code is incorrect and hash should be assigned the rotated value returned from rol32. Thanks to David Lebrun for spotting this. Signed-off-by: Colin Ian King <colin.king@canonical.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2018-07-18net: dsa: Remove VLA usageSalvatore Mesoraca
We avoid 2 VLAs by using a pre-allocated field in dsa_switch. We also try to avoid dynamic allocation whenever possible (when using fewer than bits-per-long ports, which is the common case).

2018-07-18Merge branch 'PTP-support-for-mv88e6165-family'David S. Miller
Andrew Lunn says: ==================== PTP support for mv88e6165 family The mv88e6165 family of switches supports PTP. It is however not fully compatible with the current PTP support in the mv88e6xxx driver. This patchset adds a level of abstraction to the PTP code, and then adds the code needed to support the mv88e6165 family. v2: Correctly cluster local variables in mv88e6xxx_ptp_setup() Added Acked-by: Richard Cochran <richardcochran@gmail.com> ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
2018-07-18net: dsa: mv88e6xxx: Longer timeout for PTP TX timestampAndrew Lunn
For slow processors using bit-banging MDIO, 20ms can be too short a timeout when waiting for the transmit timestamp to become available. Double it to 40ms.

2018-07-18net: dsa: mv88e6xxx: Set PTP EthertypeAndrew Lunn
For the 6352 and newer switches, the PTP Ethertype defaults to ETH_P_1588. Hence it was not explicitly set. The 6165 however defaults to 0. So explicitly set the EtherType.

2018-07-18net: dsa: mv88e6xxx: Add hwtimestamp support for the 6165Andrew Lunn
The 6165 family supports a more restricted version of hardware time stamps. Only L2 PTP is supported. All ports have to use the same EtherType, and transport spec configuration. PTP can only be enabled/disabled globally, not per port. Signed-off-by: Andrew Lunn <andrew@lunn.ch> Acked-by: Richard Cochran <richardcochran@gmail.com> Signed-off-by: David S.

2018-07-18net: dsa: mv88e6xxx: Abstract supported PTP filtersAndrew Lunn
The 6165 only supports layer L2 PTP, where as the more modern devices also support UDP and UDPv6, i.e. L4. Abstract the supported receive filters. Signed-off-by: Andrew Lunn <andrew@lunn.ch> Acked-by: Richard Cochran <richardcochran@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2018-07-18net: dsa: mv88e6xxx: Abstract HW timestamp setupAndrew Lunn
The 6165 family does not have per port PTP control registers. Also, it places the timestamp data in different registers. Abstract the current implementation of 6352 compatible PTP devices so that 6165 can be added.

2018-07-18net: dsa: mv88e6xxx: Add mv88e6165 PTP supportAndrew Lunn
The mv88e6165 family has its global clock in the PTP global registers. It does not support any form of PTP events. Add a function to read the clock, fill in an ops structure, and register it with the two members of the family.

2018-07-18net: dsa: mv88e6xxx: Add MV88E6165 AVB register accessAndrew Lunn

2018-07-18net: Move skb decrypted field, avoid explicity copyStefano Brivio
Commit 784abe24c903 ("net: Add decrypted field to skb") introduced a 'decrypted' field that is explicitly copied on skb copy and clone. Move it between headers_start[0] and headers_end[0], so that we don't need to copy it explicitly as it's copied by the memcpy() in __copy_skb_header(). While at it, drop the assignment in __skb_clone(), it was already redundant. This doesn't change the size of sk_buff or cacheline boundaries. The 15-bits hole before tc_index becomes a 14-bits hole, and will be again a 15-bits hole when this change is merged with commit 8b7008620b84 ("net: Don't copy pfmemalloc flag in __copy_skb_header()"). v2: as reported by kbuild test robot (oops, I forgot to build with CONFIG_TLS_DEVICE it seems), we can't use CHECK_SKB_FIELD() on a bit-field member. Just drop the check for the moment being, perhaps we could think of some magic to also check bit-field members one day.

Introduce the devm_pci_remap_iospace() managed API and replace the pci_remap_iospace() call with it to fix the bug.

2018-07-18lib/rhashtable: consider param->min_size when setting initial table sizeDavidlohr Bueso
rhashtable_init() currently does not take into account the user-passed min_size parameter unless param->nelem_hint is set as well. As such, the default size (number of buckets) will always be HASH_DEFAULT_SIZE even if the smallest allowed size is larger than that. Remediate this by unconditionally calling into rounded_hashtable_size() and handling things accordingly.
