2017-06-29Merge branch 'net-fix-sw-timestamping'David S. Miller
Ivan Khoronzhuk says: ==================== net: fix sw timestamping for non PTP packets This series contains several corrections connected with timestamping for cpsw and netcp drivers based on same cpts module. Based on net/next ==================== Reviewed-by: Grygorii Strashko <grygorii.strashko@ti.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2017-06-29net: ethernet: ti: netcp_ethss: use cpts to check if packet needs timestampingIvan Khoronzhuk
There is cpts function to check if packet can be timstamped with cpts. Seems that ptp_classify_raw cover all cases listed with "case". Signed-off-by: Ivan Khoronzhuk <ivan.khoronzhuk@linaro.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2017-06-29net: ethernet: ti: cpsw: fix sw timestamping for non PTP packetsIvan Khoronzhuk
The cpts can timestmap only ptp packets at this moment, so driver cannot mark every packet as though it's going to be timestamped, only because h/w timestamping for given skb is enabled with SKBTX_HW_TSTAMP. It doesn't allow to use sw timestamping, as result outgoing packet is not timestamped at all if it's not PTP and h/w timestamping is enabled. So, fix it by setting SKBTX_IN_PROGRESS only for PTP packets. Signed-off-by: Ivan Khoronzhuk <ivan.khoronzhuk@linaro.org> Signed-off-by: David S. Miller <davem@davemloft.net>

2017-06-29net: stmmac: support future possible different internal phy modeLABBE Corentin
The current way to find if the phy is internal is to compare DT phy-mode and emac_variant/internal_phy. But it will negate a possible future SoC where an external PHY use the same phy mode than the internal one. By using phy-mode = "internal" we permit to have an external PHY with the same mode than the internal one.

2017-06-28block: provide bio_uninit() free freeing integrity/task associationsJens Axboe
Wen reports significant memory leaks with DIF and O_DIRECT: "With nvme devive + T10 enabled, On a system it has 256GB and started logging /proc/meminfo & /proc/slabinfo for every minute and in an hour it increased by 15968128 kB or ~15+GB..

The patch fixes the issue. HTX has been run with +60 hours without failure." Since __blkdev_direct_IO_simple() allocates the bio on the stack, it doesn't go through the regular bio free. This means that any ancillary data allocated with the bio through the stack is not freed. Hence, we can leak the integrity data associated with the bio, if the device is using DIF/DIX. Fix this by providing a bio_uninit() and export it, so that we can use it to free this data. Note that this is a minimal fix for this issue. Any current user of bio's that are allocated outside of bio_alloc_bioset() suffers from this issue, most notably some drivers. We will fix those in a more comprehensive patch for 4.13. This also means that the commit marked as being fixed by this isn't the real culprit, it's just the most obvious one out there.

The return value ret is unitialized and garbage is being returned for the three different error conditions when setting up the PCIe BARs. Fix this by initializing ret to -ENOMEM to indicate that the BARs failed to be setup correctly.

2017-06-28ath9k: avoid potential freezing during random generator readMiaoqing Pan
In the worst case, ath9k_rng_stop() may take 10s to stop rng kthread. The time is too long for users, use wait_event_interruptible_timeout() instead of msleep_interruptible(), wakup immediately once kthread_should_stop() is true.

2017-06-28ath9k: fix an invalid pointer dereference in ath9k_rng_stop()Miaoqing Pan
The bug was triggered when do suspend/resuming continuously on Dell XPS L322X/0PJHXN version 9333 (2013) with kernel 4.12.0-041200rc4-generic. But can't reproduce on DELL E5440 + AR9300 PCIE chips. The warning is caused by accessing invalid pointer sc->rng_task. sc->rng_task is not be cleared after kthread_stop(sc->rng_task) be called in ath9k_rng_stop(). Because the kthread is stopped before ath9k_rng_kthread() be scheduled. So set sc->rng_task to null after kthread_stop(sc->rng_task) to resolve this issue.
