2022-07-28KVM: nSVM: Pull CS.Base from actual VMCB12 for soft int/ex re-injectionMaciej S. Szmigiero
enter_svm_guest_mode() first calls nested_vmcb02_prepare_control() to copy control fields from VMCB12 to the current VMCB, then nested_vmcb02_prepare_save() to perform a similar copy of the save area. This means that nested_vmcb02_prepare_control() still runs with the previous save area values in the current VMCB so it shouldn't take the L2 guest CS.Base from this area. Explicitly pull CS.Base from the actual VMCB12 instead in enter_svm_guest_mode(). Granted, having a non-zero CS.Base is a very rare thing (and even impossible in 64-bit mode), having it change between nested VMRUNs is probably even rarer, but if it happens it would create a really subtle bug so it's better to fix it upfront.

2022-07-28watch_queue: Fix missing locking in add_watch_to_object()Linus Torvalds
If a watch is being added to a queue, it needs to guard against interference from addition of a new watch, manual removal of a watch and removal of a watch due to some other queue being destroyed. KEYCTL_WATCH_KEY guards against this for the same {key,queue} pair by holding the key->sem writelocked and by holding refs on both the key and the queue - but that doesn't prevent interaction from other {key,queue} pairs. While add_watch_to_object() does take the spinlock on the event queue, it doesn't take the lock on the source's watch list. The assumption was that the caller would prevent that (say by taking key->sem) - but that doesn't prevent interference from the destruction of another queue. Fix this by locking the watcher list in add_watch_to_object().

2022-07-28watch_queue: Fix missing rcu annotationDavid Howells
Since __post_watch_notification() walks wlist->watchers with only the RCU read lock held, we need to use RCU methods to add to the list (we already use RCU methods to remove from the list).

2022-07-28s390/unwind: fix fgraph return address recoverySumanth Korikkar
When HAVE_FUNCTION_GRAPH_RET_ADDR_PTR is defined, the return address to the fgraph caller is recovered by tagging it along with the stack pointer of ftrace stack. This makes the stack unwinding more reliable. When the fgraph return address is modified to return_to_handler, ftrace_graph_ret_addr tries to restore it to the original value using tagged stack pointer. Fix this by passing tagged sp to ftrace_graph_ret_addr.

2022-07-28s390: add ELF note type for encrypted CPU state of a PV VCPUJanosch Frank
The type NT_S390_PV_CPU_DATA note contains the encrypted CPU state of a PV VCPU. It's only relevant in dumps of s390 PV VMs and can't be decrypted without a second block of encrypted data which provides key parts. Therefore we only reserve the note type here. The zgetdump tool from the s390-tools package can, together with a Customer Communication Key, be used to convert a PV VM dump into a normal VM dump. zgetdump will decrypt the CPU data and overwrite the other respective notes to make the data accessible for crash and other debugging tools.

2022-07-28s390/smp: rework absolute lowcore accessAlexander Gordeev
Temporary unsetting of the prefix page in memcpy_absolute() routine poses a risk of executing code path with unexpectedly disabled prefix page. This rework avoids the prefix page uninstalling and disabling of normal and machine check interrupts when accessing the absolute zero memory. Although memcpy_absolute() routine can access the whole memory, it is only used to update the absolute zero lowcore. This rework therefore introduces a new mechanism for the absolute zero lowcore access and scraps memcpy_absolute() routine for good. Instead, an area is reserved in the virtual memory that is used for the absolute lowcore access only. That area holds an array of 8KB virtual mappings - one per CPU. Whenever a CPU is brought online, the corresponding item is mapped to the real address of the previously installed prefix page. The absolute zero lowcore access works like this: a CPU calls the new primitive get_abs_lowcore() to obtain its 8KB mapping as a pointer to the struct lowcore. Virtual address references to that pointer get translated to the real addresses of the prefix page, which in turn gets swapped with the absolute zero memory addresses due to prefixing. Once the pointer is not needed it must be released with put_abs_lowcore() primitive: struct lowcore *abs_lc; unsigned long flags; abs_lc = get_abs_lowcore(&flags); abs_lc->... = ...; put_abs_lowcore(abs_lc, flags); To ensure the described mechanism works large segment- and region- table entries must be avoided for the 8KB mappings. Failure to do so results in usage of Region-Frame Absolute Address (RFAA) or Segment-Frame Absolute Address (SFAA) large page fields. In that case absolute addresses would be used to address the prefix page instead of the real ones and the prefixing would get bypassed.

In order to move this to the thermal.h header and allow more cleanup, we need to remove the node pointer from the structure.

2022-07-28thermal/core: Remove duplicate information when an error occursDaniel Lezcano
The pr_err already tells it is an error, it is pointless to add the 'Error:' string in the messages. Remove them.

2022-07-28thermal/core: Avoid calling ->get_trip_temp() unnecessarilyDaniel Lezcano
As the trip temperature is already available when calling the function handle_critical_trips(), pass it as a parameter instead of having this function calling the ops again to retrieve the same data.
