d3857b8f0d selftests: Add new option for client-side passwords
Add new option to nettest to specify MD5 password to use for client
side. Update fcnal-test script. This is needed for a single instance
running both server and client modes to test password mismatches.

a824e261d7 selftests: Consistently specify address for MD5 protection
nettest started with -r as the remote address for MD5 passwords.
The -m argument was added to use prefixes with a length when that
feature was added to the kernel. Since -r is used to specify
remote address for client mode, change nettest to only use -m
for MD5 passwords and update fcnal-test script.

f222c37cf7 selftests: Use separate stdout and stderr buffers in nettest
When a single instance of nettest is doing both client and
server modes, stdout and stderr messages can get interlaced
and become unreadable. Allocate a new set of buffers for the
child process handling server mode.

6469403c97 selftests: Add support to nettest to run both client and server
Add option to nettest to run both client and server within a
single instance. Client forks a child process to run the server
code. A pipe is used for the server to tell the client it has
initialized and is ready or had an error. This avoid unnecessary
sleeps to handle such race when the commands are separately launched.

f2f575840a selftests: Move address validation in nettest
IPv6 addresses can have a device name to declare a scope (e.g.,
fe80::5054:ff:fe12:3456%eth0). The next patch adds support to
switch network namespace before running client or server code
(or both), so move the address validation to the server and
client functions.

IPv4 multicast groups do not have the device scope in the address
specification, so they can be validated inline with option parsing.

This Kselftest fixes update for Linux 5.11-rc4 consists of one single fix
 to skip BPF selftests by default. BPF selftests have a hard dependency on
 cutting edge versions of tools in the BPF ecosystem including LLVM.
 
 Skipping BPF allows by default will make it easier for users interested in
 running kselftest as a whole. Users can include BPF in Kselftest build by
 via SKIP_TARGETS variable.

a2e38dffcd objtool: Don't add empty symbols to the rbtree
Building with the Clang assembler shows the following warning:

  arch/x86/kernel/ftrace_64.o: warning: objtool: missing symbol for insn at offset 0x16

The Clang assembler strips section symbols.  That ends up giving
objtool's find_func_containing() much more test coverage than normal.
Turns out, find_func_containing() doesn't work so well for overlapping
symbols:

     2: 000000000000000e     0 NOTYPE  LOCAL  DEFAULT    2 fgraph_trace
     3: 000000000000000f     0 NOTYPE  LOCAL  DEFAULT    2 trace
     4: 0000000000000000   165 FUNC    GLOBAL DEFAULT    2 __fentry__
     5: 000000000000000e     0 NOTYPE  GLOBAL DEFAULT    2 ftrace_stub

The zero-length NOTYPE symbols are inside __fentry__(), confusing the
rbtree search for any __fentry__() offset coming after a NOTYPE.

Try to avoid this problem by not adding zero-length symbols to the
rbtree.  They're rare and aren't needed in the rbtree anyway.

One caveat, this actually might not end up being the right fix.
Non-empty overlapping symbols, if they exist, could have the same
problem.  But that would need bigger changes, let's see if we can get
away with the easy fix for now.

635599bace selftests/bpf: Sync RCU before unloading bpf_testmod
If some of the subtests use module BTFs through ksyms, they will cause
bpf_prog to take a refcount on bpf_testmod module, which will prevent it from
successfully unloading. Module's refcnt is decremented when bpf_prog is freed,
which generally happens in RCU callback. So we need to trigger
syncronize_rcu() in the kernel, which can be achieved nicely with
membarrier(MEMBARRIER_CMD_SHARED) or membarrier(MEMBARRIER_CMD_GLOBAL) syscall.
So do that in kernel_sync_rcu() and make it available to other test inside the
test_progs. This synchronize_rcu() is called before attempting to unload
bpf_testmod.

c6458e72f6 bpf: Clarify return value of probe str helpers
When the buffer is too small to contain the input string, these helpers
return the length of the buffer, not the length of the original string.
This tries to make the docs totally clear about that, since "the length
of the [copied ]string" could also refer to the length of the input.

2f94ac1918 bpf: Update local storage test to check handling of null ptrs
It was found in [1] that bpf_inode_storage_get helper did not check
the nullness of the passed owner ptr which caused an oops when
dereferenced. This change incorporates the example suggested in [1] into
the local storage selftest.

The test is updated to create a temporary directory instead of just
using a tempfile. In order to replicate the issue this copied rm binary
is renamed tiggering the inode_rename with a null pointer for the
new_inode. The logic to verify the setting and deletion of the inode
local storage of the old inode is also moved to this LSM hook.

The change also removes the copy_rm function and simply shells out
to copy files and recursively delete directories and consolidates the
logic of setting the initial inode storage to the bprm_committed_creds
hook and removes the file_open hook.

a4b09a9ef9 libbpf: Add non-CO-RE variants of BPF_CORE_READ() macro family
BPF_CORE_READ(), in addition to handling CO-RE relocations, also allows much
nicer way to read data structures with nested pointers. Instead of writing
a sequence of bpf_probe_read() calls to follow links, one can just write
BPF_CORE_READ(a, b, c, d) to effectively do a->b->c->d read. This is a welcome
ability when porting BCC code, which (in most cases) allows exactly the
intuitive a->b->c->d variant.

This patch adds non-CO-RE variants of BPF_CORE_READ() family of macros for
cases where CO-RE is not supported (e.g., old kernels). In such cases, the
property of shortening a sequence of bpf_probe_read()s to a simple
BPF_PROBE_READ(a, b, c, d) invocation is still desirable, especially when
porting BCC code to libbpf. Yet, no CO-RE relocation is going to be emitted.

5316a7c013 tools: selftests: add test for changing routes with PTMU exceptions
Adds new 2 new tests to the PTMU script: pmtu_ipv4/6_route_change.

These tests explicitly test for a recently discovered problem in the
IPv6 routing framework where PMTU exceptions were not properly released
when replacing a route via "ip route change ...".

After creating PMTU exceptions, the route from the device A to R1 will be
replaced with a new route, then device A will be deleted. If the PMTU
exceptions were properly cleaned up by the kernel, this device deletion
will succeed. Otherwise, the unregistration of the device will stall, and
messages such as the following will be logged in dmesg:

unregister_netdevice: waiting for veth_A-R1 to become free. Usage count = 4

6f02b540d7 bpftool: Fix compilation failure for net.o with older glibc
For older glibc ~2.17, #include'ing both linux/if.h and net/if.h
fails due to complaints about redefinition of interface flags:

  CC       net.o
In file included from net.c:13:0:
/usr/include/linux/if.h:71:2: error: redeclaration of enumerator ‘IFF_UP’
  IFF_UP    = 1<<0,  /* sysfs */
  ^
/usr/include/net/if.h:44:5: note: previous definition of ‘IFF_UP’ was here
     IFF_UP = 0x1,  /* Interface is up.  */

The issue was fixed in kernel headers in [1], but since compilation
of net.c picks up system headers the problem can recur.

Dropping #include <linux/if.h> resolves the issue and it is
not needed for compilation anyhow.

6720869280 tools/resolve_btfids: Warn when having multiple IDs for single type
The kernel image can contain multiple types (structs/unions)
with the same name. This causes distinct type hierarchies in
BTF data and makes resolve_btfids fail with error like:

  BTFIDS  vmlinux
FAILED unresolved symbol udp6_sock

as reported by Qais Yousef [1].

This change adds warning when multiple types of the same name
are detected:

  BTFIDS  vmlinux
WARN: multiple IDs found for 'file': 526, 113351 - using 526
WARN: multiple IDs found for 'sk_buff': 2744, 113958 - using 2744

We keep the lower ID for the given type instance and let the
build continue.

Also changing the 'nr' variable name to 'nr_types' to avoid confusion.

7a6eb7c34a selftests: Skip BPF seftests by default
The BPF selftests have build time dependencies on cutting edge versions
of tools in the BPF ecosystem including LLVM which are more involved
to satisfy than more typical requirements like installing a package from
your distribution.  This causes issues for users looking at kselftest in
as a whole who find that a default build of kselftest fails and that
resolving this is time consuming and adds administrative overhead.  The
fast pace of BPF development and the need for a full BPF stack to do
substantial development or validation work on the code mean that people
working directly on it don't see a reasonable way to keep supporting
older environments without causing problems with the usability of the
BPF tests in BPF development so these requirements are unlikely to be
relaxed in the immediate future.

There is already support for skipping targets so in order to reduce the
barrier to entry for people interested in kselftest as a whole let's use
that to skip the BPF tests by default when people work with the top
level kselftest build system.  Users can still build the BPF selftests
as part of the wider kselftest build by specifying SKIP_TARGETS,
including setting an empty SKIP_TARGETS to build everything.  They can
also continue to build the BPF selftests individually in cases where
they are specifically focused on BPF.

This isn't ideal since it means people will need to take special steps
to build the BPF tests but the dependencies mean that realistically this
is already the case to some extent and it makes it easier for people to
pick up and work with the other selftests which is hopefully a net win.

65a4e52997 kunit: tool: Force the use of the 'tty' console for UML
kunit_tool relies on the UML console outputting printk() output to the
tty in order to get results. Since the default console driver could
change, pass 'console=tty' to the kernel.

This is triggered by a change[1] to use ttynull as a fallback console
driver which -- by chance or by design -- seems to have changed the
default console output on UML, breaking kunit_tool. While this may be
fixed, we should be less fragile to such changes in the default.

f981dc171c tools/power/x86/intel-speed-select: Set scaling_max_freq to base_frequency
When BIOS disables turbo, The scaling_max_freq in cpufreq sysfs will be
limited to config level 0 base frequency. But when user selects a higher
config levels, this will result in higher base frequency. But since
scaling_max_freq is still old base frequency, the performance will still
be limited. So when the turbo is disabled and cpufreq base_frequency is
higher than scaling_max_freq, update the scaling_max_freq to the
base_frequency.

da64ae2d35 xfrm: Fix wraparound in xfrm_policy_addr_delta()
Use three-way comparison for address components to avoid integer
wraparound in the result of xfrm_policy_addr_delta(). This ensures
that the search trees are built and traversed correctly.

Treat IPv4 and IPv6 similarly by returning 0 when prefixlen == 0.
Prefix /0 has only one equivalence class.

PASS: direct policy matches (exceptions and block policies after htresh change to normal)
PASS: policy matches (exceptions and block policies after htresh change to normal)

$ echo $?
0

This is because the $lret in check_xfrm() is not a local variable.
Therefore when a test failed in check_exceptions(), the non-zero $lret
will later get reset to 0 when the next test calls check_xfrm().

With this fix, the final return value will be 1. Make it easier for
testers to spot this failure.

7cf22a1c88 selftests/vm: fix building protection keys test
Commit d8cbe8bfa7 ("tools/testing/selftests/vm: fix build error") tried
to include a ARCH check for powerpc, however ARCH is not defined in the
Makefile before including lib.mk.  This makes test building to skip on
both x86 and powerpc.

Fix the arch check by replacing it using machine type as it is already
defined and used in the test.

da4282c17d selftests/bpf: Fix a compile error for BPF_F_BPRM_SECUREEXEC
When CONFIG_BPF_LSM is not configured, running bpf selftesting will show
BPF_F_BPRM_SECUREEXEC undefined error for bprm_opts.c.

The problem is that bprm_opts.c includes vmliunx.h. The vmlinux.h is
generated by "bpftool btf dump file ./vmlinux format c". On the other
hand, BPF_F_BPRM_SECUREEXEC is defined in include/uapi/linux/bpf.h
and used only in bpf_lsm.c. When CONFIG_BPF_LSM is not set, bpf_lsm
will not be compiled, so vmlinux.h will not include definition of
BPF_F_BPRM_SECUREEXEC.

Ideally, we want to compile bpf selftest regardless of the configuration
setting, so change the include file from vmlinux.h to bpf.h.

Daniel Borkmann says:

====================
pull-request: bpf 2020-12-28

The following pull-request contains BPF updates for your *net* tree.

There is a small merge conflict between bpf tree commit 69ca310f34
("bpf: Save correct stopping point in file seq iteration") and net tree
commit 66ed594409 ("bpf/task_iter: In task_file_seq_get_next use
task_lookup_next_fd_rcu"). The get_files_struct() does not exist anymore
in net, so take the hunk in HEAD and add the `info->tid = curr_tid` to
the error path:

  [...]
                curr_task = task_seq_get_next(ns, &curr_tid, true);
                if (!curr_task) {
                        info->task = NULL;
                        info->tid = curr_tid;
                        return NULL;
                }

                /* set info->task and info->tid */
  [...]

We've added 10 non-merge commits during the last 9 day(s) which contain
a total of 11 files changed, 75 insertions(+), 20 deletions(-).

The main changes are:

1) Various AF_XDP fixes such as fill/completion ring leak on failed bind and
   fixing a race in skb mode's backpressure mechanism, from Magnus Karlsson.

2) Fix latency spikes on lockdep enabled kernels by adding a rescheduling
   point to BPF hashtab initialization, from Eric Dumazet.

3) Fix a splat in task iterator by saving the correct stopping point in the
   seq file iteration, from Jonathan Lemon.

4) Fix BPF maps selftest by adding retries in case hashtab returns EBUSY
   errors on update/deletes, from Andrii Nakryiko.

5) Fix BPF selftest error reporting to something more user friendly if the
   vmlinux BTF cannot be found, from Kamal Mostafa.

 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.

5149303fdf perf probe: Fix memory leak when synthesizing SDT probes
The argv_split() function must be paired with argv_free(), else we must
keep a reference to the argv array received or do the freeing ourselves,
in synthesize_sdt_probe_command() we were simply leaking that argv[]
array.

8d4852b468 perf stat aggregation: Add separate thread member
A separate field isn't strictly required. The core field could be
re-used for thread IDs as a single field was used previously.

But separating them will avoid confusion and catch potential errors
where core IDs are read as thread IDs and vice versa.

Also remove the placeholder id field which is now no longer used.

1a270cb6b3 perf stat aggregation: Add separate socket member
Add socket as a separate member so that it doesn't have to be packed
into the int value.

When the socket ID was larger than 8 bits the output appeared corrupted
or incomplete.

For example, here on ThunderX2 'perf stat' reports a socket of -1 and an
invalid die number:

  ./perf stat -a --per-die
  The socket id number is too big.

  Performance counter stats for 'system wide':

  S-1-D255       128             687.99 msec cpu-clock                 #   57.240 CPUs utilized
  ...
  S36-D0         128             842.34 msec cpu-clock                 #   70.081 CPUs utilized
  ...

And with --per-core there is an entry with an invalid core ID:

  ./perf stat record -a --per-core
  The socket id number is too big.

  Performance counter stats for 'system wide':
  S-1-D255-C65535     128             671.04 msec cpu-clock                 #   54.112 CPUs utilized
  ...
  S36-D0-C0           4              28.27 msec cpu-clock                 #    2.279 CPUs utilized
  ...

This fixes the "Session topology" self test on ThunderX2.

After this fix the output contains the correct socket and die IDs and no
longer prints a warning about the size of the socket ID:

  ./perf stat --per-die -a

  Performance counter stats for 'system wide':

  S36-D0         128         169,869.39 msec cpu-clock                 #  127.501 CPUs utilized

fa265e59b8 perf cpumap: Add new struct for cpu aggregation
This struct currently has only a single int member so that it can be
used as a drop in replacement for the existing behaviour.

Comparison and constructor functions have also been added that will
replace usages of '==' and '= -1'.

No functional changes.

11b844b0b7 selftests/bpf: Work-around EBUSY errors from hashmap update/delete
20b6cc34ea ("bpf: Avoid hashtab deadlock with map_locked") introduced
a possibility of getting EBUSY error on lock contention, which seems to happen
very deterministically in test_maps when running 1024 threads on low-CPU
machine. In libbpf CI case, it's a 2 CPU VM and it's hitting this 100% of the
time. Work around by retrying on EBUSY (and EAGAIN, while we are at it) after
a small sleep. sched_yield() is too agressive and fails even after 20 retries,
so I went with usleep(1) for backoff.

Also log actual error returned to make it easier to see what's going on.

1375b9803e Merge branch 'akpm' (patches from Andrew)
Merge KASAN updates from Andrew Morton.

This adds a new hardware tag-based mode to KASAN.  The new mode is
similar to the existing software tag-based KASAN, but relies on arm64
Memory Tagging Extension (MTE) to perform memory and pointer tagging
(instead of shadow memory and compiler instrumentation).

By Andrey Konovalov and Vincenzo Frascino.

29f0808816 kselftest/arm64: check GCR_EL1 after context switch
This test is specific to MTE and verifies that the GCR_EL1 register is
context switched correctly.

It spawns 1024 processes and each process spawns 5 threads.  Each thread
writes a random setting of GCR_EL1 through the prctl() system call and
reads it back verifying that it is the same.  If the values are not the
same it reports a failure.

Note: The test has been extended to verify that even SYNC and ASYNC mode
setting is preserved correctly over context switching.

 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.

Merge tag 'close-range-cloexec-unshare-v5.11' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux

Pull close_range fix from Christian Brauner:
 "syzbot reported a bug when asking close_range() to unshare the file
  descriptor table and making all fds close-on-exec.

  If CLOSE_RANGE_UNSHARE the caller will receive a private file
  descriptor table in case their file descriptor table is currently
  shared before operating on the requested file descriptor range.

  For the case where the caller has requested all file descriptors to be
  actually closed via e.g. close_range(3, ~0U, CLOSE_RANGE_UNSHARE) the
  kernel knows that the caller does not need any of the file descriptors
  anymore and will optimize the close operation by only copying all
  files in the range from 0 to 3 and no others.

  However, if the caller requested CLOSE_RANGE_CLOEXEC together with
  CLOSE_RANGE_UNSHARE the caller wants to still make use of the file
  descriptors so the kernel needs to copy all of them and can't
  optimize.

  The original patch didn't account for this and thus could cause oopses
  as evidenced by the syzbot report because it assumed that all fds had
  been copied. Fix this by handling the CLOSE_RANGE_CLOEXEC case and
  copying all fds if the two flags are specified together.

  This should've been caught in the selftests but the original patch
  didn't cover this case and I didn't catch it during review. So in
  addition to the bugfix I'm also adding selftests. They will reliably
  reproduce the bug on a non-fixed kernel and allows us to catch
  regressions and verify correct behavior.

  Note, the kernel selftest tree contained a bunch of changes that made
  the original selftest fail to compile so there are small fixups in
  here make them compile without warnings"

2e7f545096 perf mem: Factor out a function to generate sort order
Now, "--phys-data" is the only option which impacts the sort order.  A
simple "if else" is enough to handle the option. But there will be more
options added, e.g. "--data-page-size", which also impact the sort
order. The code will become too complex to be maintained.

Divide the sort order string into several small pieces.  The first piece
is always the default sort string for LOAD/STORE.  Appends the specific
sort string if related option is applied.

No functional change.

a50d03e3b8 perf sort: Add sort option for data page size
Add a new sort option "data_page_size" for --mem-mode sort.  With this
option applied, perf can sort and report by sample's data page size.

Here is an example:

perf report --stdio --mem-mode
--sort=comm,symbol,phys_daddr,data_page_size

 # To display the perf.data header info, please use
 # --header/--header-only options.
 #
 #
 # Total Lost Samples: 0
 #
 # Samples: 9K of event 'mem-loads:uP'
 # Total weight : 9028
 # Sort order   : comm,symbol,phys_daddr,data_page_size
 #
 # Overhead  Command  Symbol                        Data Physical
 # Address
 # Data Page Size

selftests/core: add regression test for CLOSE_RANGE_UNSHARE | CLOSE_RANGE_CLOEXEC
This test is a minimalized version of the reproducer given by syzbot
(cf. [1]).

After introducing CLOSE_RANGE_CLOEXEC syzbot reported a crash when
CLOSE_RANGE_CLOEXEC is specified in conjunction with
CLOSE_RANGE_UNSHARE. When CLOSE_RANGE_UNSHARE is specified the caller
will receive a private file descriptor table in case their file
descriptor table is currently shared.
For the case where the caller has requested all file descriptors to be
actually closed via e.g. close_range(3, ~0U, 0) the kernel knows that
the caller does not need any of the file descriptors anymore and will
optimize the close operation by only copying all files in the range from
0 to 3 and no others.

However, if the caller requested CLOSE_RANGE_CLOEXEC together with
CLOSE_RANGE_UNSHARE the caller wants to still make use of the file
descriptors so the kernel needs to copy all of them and can't optimize.

The original patch didn't account for this and thus could cause oopses
as evidenced by the syzbot report. Add tests for this regression.

We first create a huge gap in the fd table. When we now call
CLOSE_RANGE_UNSHARE with a shared fd table and and with ~0U as upper
bound the kernel will only copy up to fd1 file descriptors into the new
fd table. If the kernel is buggy and doesn't handle CLOSE_RANGE_CLOEXEC
correctly it will not have copied all file descriptors and we will oops!

This test passes on a fixed kernel and will trigger an oops on a buggy
kernel.

4bba4c4bb0 tools headers: Get tools's linux/compiler.h closer to the kernel's
We're cherry picking stuff from the kernel to allow for the other
headers that we keep in sync via tools/perf/check-headers.sh to work,
so introduce linux/compiler_types.h and from there get the compiler
specific stuff.

a409ed156a This is the bulk of the GPIO changes for the v5.11 kernel cycle:
Core changes:
 
 - Retired the old set-up function for GPIO IRQ chips. All chips
   now use the template struct gpio_irq_chip and pass that to the core
   to be set up alongside the gpio_chip. We can finally get rid of
   the old cruft.
 
 - Some refactoring and clean up of the core code.
 
 - Support edge event timestamps to be stamped using REALTIME
   (wall clock) timestamps. We have found solid use cases for
   this, so we support it.
 
 New drivers:
 
 - MStar MSC313 GPIO driver.
 
 - HiSilicon GPIO driver.
 
 Driver improvements:
 
 - The PCA953x driver now also supports the NXP PCAL9554B/C chips.
 
 - The mockup driver can now be probed from the device tree which
   is pretty useful for virtual prototyping of devices.
 
 - The Rcar driver now supports .get_multiple()
 
 - The MXC driver dropped some legacy and became a pure device
   tree client.
 
 - The Exar driver was moved over to the IDA interface for
   enumerating, and also switched over to using regmap for
   register access.

219d04992b mptcp: push pending frames when subflow has free space
When multiple subflows are active, we can receive a
window update on subflow with no write space available.
MPTCP will try to push frames on such subflow and will
fail. Pending frames will be pushed only after receiving
a window update on a subflow with some wspace available.

Overall the above could lead to suboptimal aggregate
bandwidth usage.

Instead, we should try to push pending frames as soon as
the subflow reaches both conditions mentioned above.

We can finally enable self-tests with asymmetric links,
as the above makes them finally pass.

8abceacff8 perf debug: Add debug_set_file function
Allow to set debug output file via new debug_set_file function.

It's called during perf startup in perf_debug_setup to set stderr file
as default and any perf command can set it later to different file.

It will be used in perf daemon command to get verbose output into log
file.

7cfcd1e016 perf tools: Add evlist__disable_evsel/evlist__enable_evsel
Adding interface to enable/disable single event in the evlist based on
its name. It will be used later in new control enable/disable interface.

Keeping the evlist::enabled true when one or more events are enabled so
the toggle can work properly and toggle evlist to disabled state.

c2337d6719 perf metricgroup: Fix metrics using aliases covering multiple PMUs
Support for metric expressions using aliases which cover multiple PMUs
is broken. Consider the following test metric expression:

  "MetricExpr": "UNC_CBO_XSNP_RESPONSE.MISS_XCORE * UNC_CBO_XSNP_RESPONSE.MISS_EVICTION"

When used on my broadwell, "perf stat" gives:

  unc_cbo_xsnp_response.miss_eviction -> uncore_cbox_1/umask=0x81,event=0x22/
  unc_cbo_xsnp_response.miss_eviction -> uncore_cbox_0/umask=0x81,event=0x22/
  unc_cbo_xsnp_response.miss_xcore -> uncore_cbox_1/umask=0x41,event=0x22/
  unc_cbo_xsnp_response.miss_xcore -> uncore_cbox_0/umask=0x41,event=0x22/
  Control descriptor is not initialized
  unc_cbo_xsnp_response.miss_eviction: 3645925 1000850523 1000850523
  unc_cbo_xsnp_response.miss_xcore: 106850 1000850523 1000850523

   Performance counter stats for 'system wide':

           3,645,925      unc_cbo_xsnp_response.miss_eviction # 389567086250.00 test_metric_inc
             106,850      unc_cbo_xsnp_response.miss_xcore

         1.000883096 seconds time elapsed

Notice that only the results from one PMU are included. Fix the logic of
find_evsel_group() to enable events which apply to multiple PMUs, by
checking if the event pmu_name matches that of the metric event.

With that, "perf stat" now gives:

  unc_cbo_xsnp_response.miss_eviction -> uncore_cbox_1/umask=0x81,event=0x22/
  unc_cbo_xsnp_response.miss_eviction -> uncore_cbox_0/umask=0x81,event=0x22/
