2020-09-20bnxt_en: Protect bnxt_set_eee() and bnxt_set_pauseparam() with mutex.Michael Chan
All changes related to bp->link_info require the protection of the link_lock mutex. It's not sufficient to rely just on RTNL. Fixes: 163e9ef63641 ("bnxt_en: Fix race when modifying pause settings.")

2020-09-20bnxt_en: return proper error codes in bnxt_show_tempEdwin Peer
Returning "unknown" as a temperature value violates the hwmon interface rules. Appropriate error codes should be returned via device_attribute show instead. These will ultimately be propagated to the user via the file system interface. In addition to the corrected error handling, it is an even better idea to not present the sensor in sysfs at all if it is known that the read will definitely fail. Given that temp1_input is currently the only sensor reported, ensure no hwmon registration if TEMP_MONITOR_QUERY is not supported or if it will fail due to access permissions. Something smarter may be needed if and when other sensors are added.

Using strlcpy() to copy from VPD is not correct because VPD strings are not necessarily NULL terminated. Use memcpy() to copy the VPD length up to the destination buffer size - 1. The destination is zeroed memory so it will always be NULL terminated.

2020-09-20dax: Fix stack overflow when mounting fsdax pmem deviceAdrian Huang
When mounting fsdax pmem device, commit 6180bb446ab6 ("dax: fix detection of dax support for non-persistent memory block devices") introduces the stack overflow [1][2]. Here is the call path for mounting ext4 file system: ext4_fill_super bdev_dax_supported __bdev_dax_supported dax_supported generic_fsdax_supported __generic_fsdax_supported bdev_dax_supported The call path leads to the infinite calling loop, so we cannot call bdev_dax_supported() in __generic_fsdax_supported(). The sanity checking of the variable 'dax_dev' is moved prior to the two bdev_dax_pgoff() checks [3][4].

2020-09-20dm: Call proper helper to determine dax supportJan Kara
DM was calling generic_fsdax_supported() to determine whether a device referenced in the DM table supports DAX. However this is a helper for "leaf" device drivers so that they don't have to duplicate common generic checks. High level code should call dax_supported() helper which that calls into appropriate helper for the particular device. This problem manifested itself as kernel messages: dm-3: error: dax access failed (-95) when lvm2-testsuite run in cases where a DM device was stacked on top of another DM device.

2020-09-19RISC-V: Resurrect the MMIO timer implementation for M-mode systemsPalmer Dabbelt
The K210 doesn't implement rdtime in M-mode, and since that's where Linux runs in the NOMMU systems that means we can't use rdtime. The K210 is the only system that anyone is currently running NOMMU or M-mode on, so here we're just inlining the timer read directly. This also adds the CLINT driver as an !MMU dependency, as it's currently the only timer driver availiable for these systems and without it we get a build failure for some configurations.

2020-09-18net: mscc: ocelot: add locking for the port TX timestamp IDVladimir Oltean
The ocelot_port->ts_id is used to: (a) populate skb->cb[0] for matching the TX timestamp in the PTP IRQ with an skb. (b) populate the REW_OP from the injection header of the ongoing skb. Only then is ocelot_port->ts_id incremented. This is a problem because, at least theoretically, another timestampable skb might use the same ocelot_port->ts_id before that is incremented. Normally all transmit calls are serialized by the netdev transmit spinlock, but in this case, ocelot_port_add_txtstamp_skb() is also called by DSA, which has started declaring the NETIF_F_LLTX feature since commit 2b86cb829976 ("net: dsa: declare lockless TX feature for slave ports"). So the logic of using and incrementing the timestamp id should be atomic per port. The solution is to use the global ocelot_port->ts_id only while protected by the associated ocelot_port->ts_id_lock. That's where we populate skb->cb[0]. Note that for ocelot, ocelot_port_add_txtstamp_skb is called for the actual skb, but for felix, it is called for the skb's clone. That is something which will also be changed in the future.

2020-09-18iommu/amd: Restore IRTE.RemapEn bit for amd_iommu_activate_guest_modeSuravee Suthikulpanit
Commit e52d58d54a32 ("iommu/amd: Use cmpxchg_double() when updating 128-bit IRTE") removed an assumption that modify_irte_ga always set the valid bit, which requires the callers to set the appropriate value for the struct irte_ga.valid bit before calling the function. Similar to the commit 26e495f34107 ("iommu/amd: Restore IRTE.RemapEn bit after programming IRTE"), which is for the function amd_iommu_deactivate_guest_mode(). The same change is also needed for the amd_iommu_activate_guest_mode(). Otherwise, this could trigger IO_PAGE_FAULT for the VFIO based VMs with AVIC enabled.
