2019-10-18net/mlx5e: kTLS, Remove unneeded cipher type checksTariq Toukan
Cipher type is checked upon connection addition. No need to recheck it per every TX resync invocation.

2019-10-18net/mlx5e: kTLS, Limit DUMP wqe sizeTariq Toukan
HW expects the data size in DUMP WQEs to be up to MTU. Make sure they are in range. We elevate the frag page refcount by 'n-1', in addition to the one obtained in tx_sync_info_get(), having an overall of 'n' references. We bulk increments by using a single page_ref_add() command, to optimize perfermance. The refcounts are released one by one, by the corresponding completions.

All references for frag pages that are obtained in tx_sync_info_get() should be released. Release usually occurs in the corresponding CQE of the WQE. In error flows, not all fragments have a WQE posted for them, hence no matching CQE will be generated. For these pages, release the reference in the error flow.

2019-10-18USB: ldusb: fix read info leaksJohan Hovold
Fix broken read implementation, which could be used to trigger slab info leaks. The driver failed to check if the custom ring buffer was still empty when waking up after having waited for more data. This would happen on every interrupt-in completion, even if no data had been added to the ring buffer (e.g. on disconnect events). Due to missing sanity checks and uninitialised (kmalloced) ring-buffer entries, this meant that huge slab info leaks could easily be triggered. Note that the empty-buffer check after wakeup is enough to fix the info leak on disconnect, but let's clear the buffer on allocation and add a sanity check to read() to prevent further leaks.

This commit set attempts to correct the errors I observed in my testing. The first commit applies to all internal PHYs to restore proper reporting of link status when a link comes up. The second commit restores the soft reset to the initialization of the older internal EPHYs used by 40nm Set-Top Box devices. The third corrects a bug I introduced when removing excessive soft resets by altering the initialization sequence in a way that keeps the GENETv3 MAC interface happy. Finally, I observed a number of issues when manually configuring the network interface of the older EPHYs that appear to be resolved by the fourth commit. ==================== Signed-off-by: David S.

2019-10-18net: bcmgenet: reset 40nm EPHY on energy detectDoug Berger
The EPHY integrated into the 40nm Set-Top Box devices can falsely detect energy when connected to a disabled peer interface. When the peer interface is enabled the EPHY will detect and report the link as active, but on occasion may get into a state where it is not able to exchange data with the connected GENET MAC. This issue has not been observed when the link parameters are auto-negotiated; however, it has been observed with a manually configured link. It has been empirically determined that issuing a soft reset to the EPHY when energy is detected prevents it from getting into this bad state.

2019-10-18net: bcmgenet: soft reset 40nm EPHYs before MAC initDoug Berger
It turns out that the "Workaround for putting the PHY in IDDQ mode" used by the internal EPHYs on 40nm Set-Top Box chips when powering down puts the interface to the GENET MAC in a state that can cause subsequent MAC resets to be incomplete. Rather than restore the forced soft reset when powering up internal PHYs, this commit moves the invocation of phy_init_hw earlier in the MAC initialization sequence to just before the MAC reset in the open and resume functions. This allows the interface to be stable and allows the MAC resets to be successful. The bcmgenet_mii_probe() function is split in two to accommodate this. The new function bcmgenet_mii_connect() handles the first half of the functionality before the MAC initialization, and the bcmgenet_mii_config() function is extended to provide the remaining PHY configuration following the MAC initialization.

2019-10-18bus: ti-sysc: Fix watchdog quirk handlingTony Lindgren
I noticed that when probed with ti-sysc, watchdog can trigger on am3, am4 and dra7 causing a device reset. Turns out I made several mistakes implementing the watchdog quirk handling: 1. We must do both writes to spr register 2. We must also call the reset quirk on disable 3. On am3 and am4 we need to also set swsup quirk flag I probably only tested this earlier with watchdog service running when the watchdog never gets disabled.

2019-10-18ARM: OMAP2+: Add pdata for OMAP3 ISP IOMMUSuman Anna
The OMAP3 ISP IOMMU does not have any reset lines, so it didn't need any pdata previously. The OMAP IOMMU driver now requires the platform data ops for device_enable/idle on all the IOMMU devices after commit db8918f61d51 ("iommu/omap: streamline enable/disable through runtime pm callbacks") to enable/disable the clocks properly and maintain the reference count and the omap_hwmod state machine. So, add these callbacks through iommu pdata quirks for the OMAP3 ISP IOMMU. Signed-off-by: Suman Anna <s-anna@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>

2019-10-18iommu/vt-d: Return the correct dma mask when we are bypassing the IOMMUArvind Sankar
We must return a mask covering the full physical RAM when bypassing the IOMMU mapping. Also, in iommu_need_mapping, we need to check using dma_direct_get_required_mask to ensure that the device's dma_mask can cover physical RAM before deciding to bypass IOMMU mapping.

In the current code, the nvme is using a fixed 4k PRP entry size, but if the kernel use a page size which is more than 4k, we should consider the situation that the bv_offset may be larger than the dev->ctrl.page_size. Otherwise we may miss setting the prp2 and then cause the command can't be executed correctly.

2019-10-18symbol namespaces: revert to previous __ksymtab name schemeMatthias Maennich
The introduction of Symbol Namespaces changed the naming schema of the __ksymtab entries from __kysmtab__symbol to __ksymtab_NAMESPACE.symbol. That caused some breakages in tools that depend on the name layout in either the binaries(vmlinux,*.ko) or in System.map. E.g. kmod's depmod would not be able to read System.map without a patch to support symbol namespaces. A warning reported by depmod for namespaced symbols would look like depmod: WARNING: [...]/uas.ko needs unknown symbol usb_stor_adjust_quirks In order to address this issue, revert to the original naming scheme and rather read the __kstrtabns_<symbol> entries and their corresponding values from __ksymtab_strings to update the namespace values for symbols. After having read all symbols and handled them in handle_modversions(), the symbols are created. In a second pass, read the __kstrtabns_ entries and update the namespaces accordingly. Fixes: 8651ec01daed ("module: add support for symbol namespaces.")
