34acb833cc RDMA/irdma: Validate udata inlen and outlen
Currently ib_copy_from_udata and ib_copy_to_udata could underfill
the request and response buffer if the user-space passes an undersized
value for udata->inlen or udata->outlen respectively [1]
This could lead to undesirable behavior.

Zero initing the buffer only goes as far as preventing using the buffer
uninitialized.

Validate udata->inlen and udata->outlen passed from user-space to ensure
they are at least the required minimum size.

A number of asynchronous event (AE) ids were not aligned to the
correct flush_code and event_type. Fix these up so that the
correct IBV error and event codes are returned to application.

Also, add handling for new AE ids like IRDMA_AE_INVALID_REQUEST to
return the correct WC error code.

13ad1125b9 RDMA/mlx5: Don't compare mkey tags in DEVX indirect mkey
According to the ib spec:
If the CI supports the Base Memory Management Extensions defined in this
specification, the L_Key format must consist of:
24 bit index in the most significant bits of the R_Key, and
8 bit key in the least significant bits of the R_Key
Through a successful Allocate L_Key verb invocation, the CI must let the
consumer own the key portion of the returned R_Key

Therefore, when creating a mkey using DEVX, the consumer is allowed to
change the key part. The kernel should compare only the index part of a
R_Key to determine equality with another R_Key.

Adding capability in order not to break backward compatibility.

Fixes: 534fd7aac5 ("IB/mlx5: Manage indirection mkey upon DEVX flow for ODP")

   This is the biggest change for this pull request. It introduces the
   runtime verification that is necessary for running Linux on safety
   critical systems. It allows for deterministic automata models to be
   inserted into the kernel that will attach to tracepoints, where the
   information on these tracepoints will move the model from state to state.
   If a state is encountered that does not belong to the model, it will then
   activate a given reactor, that could just inform the user or even panic
   the kernel (for which safety critical systems will detect and can recover
   from).
 
 - Two monitor models are also added: Wakeup In Preemptive (WIP - not to be
   confused with "work in progress"), and Wakeup While Not Running (WWNR).
 
 - Added __vstring() helper to the TRACE_EVENT() macro to replace several
   vsnprintf() usages that were all doing it wrong.
 
 - eprobes now can have their event autogenerated when the event name is left
   off.
 
 - The rest is various cleanups and fixes.

  - Replace rwlocks with RCU for better fairness in ping, raw sockets
    and IP multicast router.
 
  - Network-side support for IO uring zero-copy send.
 
  - A few skb drop reason improvements, including codegen the source file
    with string mapping instead of using macro magic.
 
  - Rename reference tracking helpers to a more consistent
    netdev_* schema.
 
  - Adapt u64_stats_t type to address load/store tearing issues.
 
  - Refine debug helper usage to reduce the log noise caused by bots.
 
 BPF

    operation.
 
  - Add support for 64 bits enum, to match types exposed by kernel.
 
  - Introduce support for sleepable uprobes program.
 
  - Introduce support for enum textual representation in libbpf.
 
  - New helpers to implement synproxy with eBPF/XDP.
 
  - Improve loop performances, inlining indirect calls when
    possible.
 
  - Removed all the deprecated libbpf APIs.
 
  - Implement new eBPF-based LSM flavor.

Pull networking changes from Paolo Abeni:
 "Core:

   - Refactor the forward memory allocation to better cope with memory
     pressure with many open sockets, moving from a per socket cache to
     a per-CPU one

   - Replace rwlocks with RCU for better fairness in ping, raw sockets
     and IP multicast router.

   - Network-side support for IO uring zero-copy send.

   - A few skb drop reason improvements, including codegen the source
     file with string mapping instead of using macro magic.

   - Rename reference tracking helpers to a more consistent netdev_*
     schema.

   - Adapt u64_stats_t type to address load/store tearing issues.

   - Refine debug helper usage to reduce the log noise caused by bots.

   - Improve socket map performance, avoiding skb cloning on read
     operation.

   - Add support for 64 bits enum, to match types exposed by kernel.

   - Introduce support for sleepable uprobes program.
