2020-07-29ice: fix overwriting TX/RX descriptor values when rebuilding VSIPaul M Stillwell Jr
If a user sets the value of the TX or RX descriptors to some non-default value using 'ethtool -G' then we need to not overwrite the values when we rebuild the VSI. The VSI rebuild could happen as a result of a user setting the number of queues via the 'ethtool -L' command. Fix this by checking to see if the value we have stored is non-zero and if it is then don't change the value.

2020-07-29ice: return correct error code from ice_aq_sw_rulesKiran Patil
Return ICE_ERR_DOES_NOT_EXIST return code if admin command error code is ICE_AQ_RC_ENOENT (not exist). ice_aq_sw_rules is used when switch rule is getting added/deleted/updated. In case of delete/update switch rule, admin command can return ICE_AQ_RC_ENOENT error code if such rule does not exist, hence return ICE_ERR_DOES_NOT_EXIST error code from ice_aq_sw_rule, so that caller of this function can decide how to handle ICE_ERR_DOES_NOT_EXIST.

2020-07-29ice: restore VF MSI-X state during PCI resetNick Nunley
During a PCI FLR the MSI-X Enable flag in the VF PCI MSI-X capability register will be cleared. This can lead to issues when a VF is assigned to a VM because in these cases the VF driver receives no indication of the PF PCI error/reset and additionally it is incapable of restoring the cleared flag in the hypervisor configuration space without fully reinitializing the driver interrupt functionality. Since the VF driver is unable to easily resolve this condition on its own, restore the VF MSI-X flag during the PF PCI reset handling.

2020-07-29ice: fix link event handling timingDave Ertman
When the driver experiences a link event (especially link up) there can be multiple events generated. Some of these are link fault and still have a state of DOWN set. The problem happens when the link comes UP during the PF driver handling one of the LINK DOWN events. The status of the link is updated and is now seen as UP, so when the actual LINK UP event comes, the port information has already been updated to be seen as UP, even though none of the UP activities have been completed. After the link information has been updated in the link handler and evaluated for MEDIA PRESENT, if the state of the link has been changed to UP, treat the DOWN event as an UP event since the link is now UP.

2020-07-29ice: Fix link broken after GLOBR resetDave Ertman
After a GLOBR, the link was broken so that a link up situation was being seen as a link down. The problem was that the rebuild process was updating the port_info link status without doing any of the other things that need to be done when link changes. This was causing the port_info struct to have current "UP" information so that any further UP interrupts were skipped as redundant. The rebuild flow should *not* be updating the port_info struct link information, so eliminate this and leave it to the link event handling code.

2020-07-29ice: Implement LFC workaroundDave Ertman
There is a bug where the LFC settings are not being preserved through a link event. The registers in question are the ones that are touched (and restored) when a set_local_mib AQ command is performed. On a link-up event, make sure that a set_local_mib is being performed. Move the function ice_aq_set_lldp_mib() from the DCB specific ice_dcb.c to ice_common.c so that the driver always has access to this AQ command.

2020-07-29nvmem: Enforce nvmem stride in the sysfs interfaceDouglas Anderson
The 'struct nvmem_config' has a stride attribute that specifies the needed alignment for accesses into the nvmem. This is used in nvmem_cell_info_to_nvmem_cell() but not in the sysfs read/write functions. If the alignment is important in one place it's important everywhere, so let's add enforcement. For now we'll consider it totally invalid to access with the wrong alignment. We could relax this in the read case where we could just read some extra bytes and throw them away. Relaxing it in the write case seems harder (and less safe?) since we'd have to read some data first and then write it back. To keep it symmetric we'll just disallow it in both cases.

2020-07-29binder: Prevent context manager from incrementing ref 0Jann Horn
Binder is designed such that a binder_proc never has references to itself. If this rule is violated, memory corruption can occur when a process sends a transaction to itself; see e.g. <https://syzkaller.appspot.com/bug?extid=09e05aba06723a94d43d>. There is a remaining edgecase through which such a transaction-to-self can still occur from the context of a task with BINDER_SET_CONTEXT_MGR access: - task A opens /dev/binder twice, creating binder_proc instances P1 and P2 - P1 becomes context manager - P2 calls ACQUIRE on the magic handle 0, allocating index 0 in its handle table - P1 dies (by closing the /dev/binder fd and waiting a bit) - P2 becomes context manager - P2 calls ACQUIRE on the magic handle 0, allocating index 1 in its handle table [this triggers a warning: "binder: 1974:1974 tried to acquire reference to desc 0, got 1 instead"] - task B opens /dev/binder once, creating binder_proc instance P3 - P3 calls P2 (via magic handle 0) with (void*)1 as argument (two-way transaction) - P2 receives the handle and uses it to call P3 (two-way transaction) - P3 calls P2 (via magic handle 0) (two-way transaction) - P2 calls P2 (via handle 1) (two-way transaction) And then, if P2 does *NOT* accept the incoming transaction work, but instead closes the binder fd, we get a crash. Solve it by preventing the context manager from using ACQUIRE on ref 0. There shouldn't be any legitimate reason for the context manager to do that. Additionally, print a warning if someone manages to find another way to trigger a transaction-to-self bug in the future.

2020-07-29usb: xhci: Fix ASMedia ASM1142 DMA addressingForest Crossman
I've confirmed that the ASMedia ASM1142 has the same problem as the ASM2142/ASM3142, in that it too reports that it supports 64-bit DMA addresses when in fact it does not. As with the ASM2142/ASM3142, this can cause problems on systems where the upper bits matter, and adding the XHCI_NO_64BIT_SUPPORT quirk completely fixes the issue.

2020-07-29usb: xhci: define IDs for various ASMedia host controllersForest Crossman
Not all ASMedia host controllers have a device ID that matches its part number. #define some of these IDs to make it clearer at a glance which chips require what quirks.

2020-07-29x86/i8259: Use printk_deferred() to prevent deadlockThomas Gleixner
0day reported a possible circular locking dependency: Chain exists of: &irq_desc_lock_class --> console_owner --> &port_lock_key Possible unsafe locking scenario: CPU0 CPU1 ---- ---- lock(&port_lock_key); lock(console_owner); lock(&port_lock_key); lock(&irq_desc_lock_class); The reason for this is a printk() in the i8259 interrupt chip driver which is invoked with the irq descriptor lock held, which reverses the lock operations vs. printk() from arbitrary contexts. Switch the printk() to printk_deferred() to avoid that.
