e246b7c035 RDMA/cma: Don't overwrite sgid_attr after device is released
As part of the cma_dev release, that pointer will be set to NULL.  In case
it happens in rdma_bind_addr() (part of an error flow), the next call to
addr_handler() will have a call to cma_acquire_dev_by_src_ip() which will
overwrite sgid_attr without releasing it.

6f320f6990 RDMA/mlx4: Remove bogus dev_base_lock usage
It is not clear what this lock protects. If the authors wanted to ensure
that "dev" does not disappear, that is impossible, given the following
code path:

mlx4_ib_netdev_event (under RTNL mutex)
-> mlx4_ib_scan_netdevs
   -> mlx4_ib_update_qps

Also, the dev_base_lock does not protect dev->dev_addr either.

So it serves no purpose here. Remove it.

779e0bf476 RDMA/core: Do not indicate device ready when device enablement fails
In procedure ib_register_device, procedure kobject_uevent is called
(advertising that the device is ready for userspace usage) even when
device_enable_and_get() returned an error.

As a result, various RDMA modules attempted to register for the device
even while the device driver was preparing to unregister the device.

Fix this by advertising the device availability only after enabling the
device succeeds.

286e1d3f9b RDMA/core: Clean up cq pool mechanism
The CQ pool mechanism had two problems:

1. The CQ pool lists were uninitialized in the device registration error
   flow.  As a result, all the list pointers remained NULL.  This caused
   the kernel to crash (in procedure ib_cq_pool_destroy) when that error
   flow was taken (and unregister called).  The stack trace snippet:

     BUG: kernel NULL pointer dereference, address: 0000000000000000

2. At device unregister, when cleaning up the cq pool, the cq's in the
   pool lists were freed, but the cq entries were left in the list.

The fix for the first issue is to initialize the cq pool lists when the
ib_device structure is allocated for a new device (in procedure
_ib_alloc_device).

The fix for the second problem is to delete cq entries from the pool lists
when cleaning up the cq pool.

In addition, procedure ib_cq_pool_destroy() is renamed to the more
appropriate name ib_cq_pool_cleanup().

0583531bb9 RDMA/iser: Remove in_interrupt() usage
iser_initialize_task_headers() uses in_interrupt() to find out if it is
safe to acquire a mutex.

in_interrupt() is deprecated as it is ill defined and does not provide
what it suggests. Aside of that it covers only parts of the contexts in
which a mutex may not be acquired.

The following callchains exist:

   -> session->tt->init_task() (iscsi_iser_task_init())

In iscsi_iser_task_xmit() there is this check:
   if (!task->sc)
      return iscsi_iser_mtask_xmit(conn, task);

so it does end up in iser_initialize_task_headers() and
iser_initialize_task_headers() relies on iscsi_task::sc == NULL.

Remove conditional locking of iser_conn::state_mutex because there is no
call chain to do so. Remove the goto label and return early now that there
is no clean up needed.

ca991a7d14 RDMA/mlx5: Assign dev to DM MR
Currently, DM MR registration flow doesn't set the mlx5_ib_dev pointer and
can cause a NULL pointer dereference if userspace dumps the MR via rdma
tool.

Assign the IB device together with the other fields and remove the
redundant reference of mlx5_ib_dev from mlx5_ib_mr.

ef3642c4f5 RDMA/mlx5: Fix error unwinds for rereg_mr
This is all a giant train wreck of error handling, in many cases the MR is
left in some corrupted state where continuing on is going to lead to
chaos, or various unwinds/order is missed.

rereg had three possible completely different actions, depending on flags
and various details about the MR. Split the three actions into three
functions, and call the right action from the start.

For each action carefully design the error handling to fit the action:

- UMR access/PD update is a simple UMR, if it fails the MR isn't changed,
  so do nothing

- PAS update over UMR is multiple UMR operations. To keep everything sane
  revoke access to the MKey while it is being changed and restore it once
  the MR is correct.

- Recreating the mkey should completely build a parallel MR with a fully
  loaded PAS then swap and destroy the old one. If it fails the original
  should be left untouched. This is handled in the core code. Directly
  call the normal MR creation functions, possibly re-using the existing
  umem.

Add support for working with ODP MRs. The READ/WRITE access flags can be
changed by UMR and we can trivially convert to/from ODP MRs using the
logic to build a completely new MR.

This new logic also fixes various problems with MRs continuing to work
while their PAS lists are no longer valid, eg during a page size change.

6e0954b11c RDMA/uverbs: Allow drivers to create a new HW object during rereg_mr
mlx5 has an ugly flow where it tries to allocate a new MR and replace the
existing MR in the same memory during rereg. This is very complicated and
buggy. Instead of trying to replace in-place inside the driver, provide
support from uverbs to change the entire HW object assigned to a handle
during rereg_mr.

Since destroying a MR is allowed to fail (ie if a MW is pointing at it)
and can't be detected in advance, the algorithm creates a completely new
uobject to hold the new MR and swaps the IDR entries of the two objects.

The old MR in the temporary IDR entry is destroyed, and if it fails
rereg_mr succeeds and destruction is deferred to FD release. This
complexity is why this cannot live in a driver safely.

aae5ab854e RISC-V Fixes for 5.10-rc6
I've collected a handful of fixes over the past few weeks:
 
 * A fix to un-break the build-id argument to the vDSO build, which is necessary
   for the LLVM linker.
 * A fix to initialize the jump label subsystem, without which it (and all the
   stuff that uses it) doesn't actually function.
 * A fix to include <asm/barrier.h> from <vdso/processor.h>, without which some
   drivers won't compile.
 
 I know it's the holidays, but I had some hiccups getting this tested earlier
 this week so it's just going out now.  None of these are tremendously urgent,
 so if they don't make rc6 it's not a big deal.  I'll have some more fixes
 coming next week either way.

ca579827c9 perf tools for v5.10: 4th batch
- Fix die_entrypc() when DW_AT_ranges DWARF attribute not available.
 
 - Cope with broken DWARF (missing DW_AT_declaration) generated by some recent
   gcc versions.
 
 - Do not generate CGROUP metadata events when not asked to in 'perf record'.
 
 - Use proper CPU for shadow stats in 'perf stat'.
 
 - Update copy of libbpf's hashmap.c, silencing tools/perf build warning.
 
 - Fix return value in 'perf diff'.
 
 Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
 
 Test results:
 
 The first ones are container based builds of tools/perf with and without libelf
 support.  Where clang is available, it is also used to build perf with/without
 libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
 when clang and its devel libraries are installed.
 
 The objtool and samples/bpf/ builds are disabled now that I'm switching from
 using the sources in a local volume to fetching them from a http server to
 build it inside the container, to make it easier to build in a container cluster.
 Those will come back later.
 
 Several are cross builds, the ones with -x-ARCH and the android one, and those
 may not have all the features built, due to lack of multi-arch devel packages,
 available and being used so far on just a few, like
 debian:experimental-x-{arm64,mipsel}.
 
 The 'perf test' one will perform a variety of tests exercising
 tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
 with a variety of command line event specifications to then intercept the
 sys_perf_event syscall to check that the perf_event_attr fields are set up as
 expected, among a variety of other unit tests.
 
 Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
 with a variety of feature sets, exercising the build with an incomplete set of
 features as well as with a complete one. It is planned to have it run on each
 of the containers mentioned above, using some container orchestration
 infrastructure. Get in contact if interested in helping having this in place.
