2016-05-15powerpc/fsl-pci: Add a workaround for PCI 5 erratachenhui zhao
Issue: As a master, the PCI IP block can combine a memory write to the last PCI double word (4 bytes) of a cacheline with a 4 byte memory write to the first PCI double word of the subsequent cacheline. This affects 32-bit PCI target devices that blindly assert STOP on memory-write transactions, without detecting that the data beat being transferred is the last data beat of the transaction. It can cause a hang. PCI-X operation is not affected by this erratum. Workaround: Setting the bit MDS in the PCI Bus Function Register will disable the combining of crossing cacheline boundary requests into one burst transaction. Therefore, it can prevent the errata scenario from occurring. This errata exists in MPC8543, MPC8543E, MPC8545, MPC8545E, MPC8547, MPC8547E, MPC8548 and MPC8548E. Refer to PCI 5 in MPC8548 errata document.

2016-05-15locking/rwsem: Fix down_write_killable()Peter Zijlstra
The new signal_pending exit path in __rwsem_down_write_failed_common() was fingered as breaking his kernel by Tetsuo Handa. Upon inspection it was found that there are two things wrong with it; - it forgets to remove WAITING_BIAS if it leaves the list empty, or - it forgets to wake further waiters that were blocked on the now removed waiter. Especially the first issue causes new lock attempts to block and stall indefinitely, as the code assumes that pending waiters mean there is an owner that will wake when it releases the lock.

git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue Jeff Kirsher says: ==================== 40GbE Intel Wired LAN Driver Updates 2016-05-14 This series contains updates to i40e and i40evf. Kevin adds support to disable link on all ports and changes bits set for telling firmware the PHY needs to be modified by the driver. Anjali adds a feature to enable/disable all multicast for a trusted VF. Added priv-flag knob to configure global true promiscuous support. Shannon adds the support code for calling the admin queue API call aq_set_switch_config(). Mitch modifies the VF, to log a message if an untrusted VF attempts to configure promiscuous mode, but lies to it and returns everything is ok instead of returning an error. Corrects the logic for reporting the receive packet hash. Fixed the adding of a broadcast filter for VFs, since that all VSIs are configured to receive broadcasts as default, so do not need to add a filter. Catherine refactors the ethtool get_settings to report the possible supported link modes from what we know about the current PHY type and that with the firmware supported PHY types. Jacob changes the driver to use WARN_ONCE in order to highlight the issue, but do not display a warning every time when receive hang message is received. Akeem corrects receive ptype payload layer for non_tunneled IPv6, when it should be layer 4 for UDP, instead of layer 3.

2016-05-15bnxt_en: Improve the delay logic for firmware response.Michael Chan
The current code has 2 problems: 1. The maximum wait time is not long enough. It is about 60% of the duration specified by the firmware. It is calling usleep_range(600, 800) for every 1 msec we are supposed to wait. 2. The granularity of the delay is too coarse. Many simple firmware commands finish in 25 usec or less. We fix these 2 issues by multiplying the original 1 msec loop counter by 40 and calling usleep_range(25, 40) for each iteration. There is also a second delay loop to wait for the last DMA word to complete. This delay loop should be a very short 5 usec wait. This change results in much faster bring-up/down time: Before the patch: time ip link set p4p1 up real 0m0.120s user 0m0.001s sys 0m0.009s After the patch: time ip link set p4p1 up real 0m0.030s user 0m0.000s sys 0m0.010s Signed-off-by: Michael Chan <michael.chan@broadcom.com> Signed-off-by: David S.

2016-05-14net/route: enforce hoplimit max valuePaolo Abeni
Currently, when creating or updating a route, no check is performed in both ipv4 and ipv6 code to the hoplimit value. The caller can i.e. set hoplimit to 256, and when such route will be used, packets will be sent with hoplimit/ttl equal to 0. This commit adds checks for the RTAX_HOPLIMIT value, in both ipv4 ipv6 route code, substituting any value greater than 255 with 255. This is consistent with what is currently done for ADVMSS and MTU in the ipv4 code. Signed-off-by: Paolo Abeni <pabeni@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>

The slab name ends up being visible in the directory structure under /sys, and even if you don't have access rights to the file you can see the filenames. Just use a 64-bit counter instead of the pointer to the 'net' structure to generate a unique name. This code will go away in 4.7 when the conntrack code moves to a single kmemcache, but this is the backportable simple solution to avoiding leaking kernel pointers to user space.
