db3cb5c11a selftests/ftrace: Fix multiple kprobe testcase
[ Upstream commit 5cc6c8d4a99d0ee4d5466498e258e593df1d3eb6 ]

Fix multiple kprobe event testcase to work it correctly.
There are 2 bugfixes.
 - Since `wc -l FILE` returns not only line number but also
   FILE filename, following "if" statement always failed.
   Fix this bug by replacing it with 'cat FILE | wc -l'
 - Since "while do-done loop" block with pipeline becomes a
   subshell, $N local variable is not update outside of
   the loop.
   Fix this bug by using actual target number (256) instead
   of $N.

cb3b83a115 libtraceevent: Fix lib installation with O=
[ Upstream commit 587db8ebdac2c5eb3a8851e16b26f2e2711ab797 ]

When we use 'O=' with make to build libtraceevent in a separate folder
it fails to install libtraceevent.a and libtraceevent.so.1.1.0 with the
error:

  INSTALL  /home/sudip/linux/obj-trace/libtraceevent.a
  INSTALL  /home/sudip/linux/obj-trace/libtraceevent.so.1.1.0

  cp: cannot stat 'libtraceevent.a': No such file or directory
  Makefile:225: recipe for target 'install_lib' failed
  make: *** [install_lib] Error 1

I used the command:

  make O=../../../obj-trace DESTDIR=~/test prefix==/usr  install

It turns out libtraceevent Makefile, even though it builds in a separate
folder, searches for libtraceevent.a and libtraceevent.so.1.1.0 in its
source folder.

So, add the 'OUTPUT' prefix to the source path so that 'make' looks for
the files in the correct place.

107726ad04 selftests: rtnetlink: add addresses with fixed life time
[ Upstream commit 3cfa148826e3c666da1cc2a43fbe8689e2650636 ]

This exercises kernel code path that deal with addresses that have
a limited lifetime.

Without previous fix, this triggers following crash on net-next:
 BUG: KASAN: null-ptr-deref in check_lifetime+0x403/0x670
 Read of size 8 at addr 0000000000000010 by task kworker [..]

349e05e9c9 rseq/selftests: Fix: Namespace gettid() for compatibility with glibc 2.30
commit 8df34c56321479bfa1ec732c675b686c2b4df412 upstream.

glibc 2.30 introduces gettid() in public headers, which clashes with
the internal static definition within rseq selftests.

Rename gettid() to rseq_gettid() to eliminate this symbol name clash.

332ed88d96 perf strbuf: Remove redundant va_end() in strbuf_addv()
commit 099be748865eece21362aee416c350c0b1ae34df upstream.

Each call to va_copy() should have one, and only one, corresponding call
to va_end(). In strbuf_addv() some code paths result in va_end() getting
called multiple times. Remove the superfluous va_end().

b520826332 perf regs: Make perf_reg_name() return "unknown" instead of NULL
[ Upstream commit 5b596e0ff0e1852197d4c82d3314db5e43126bf7 ]

To avoid breaking the build on arches where this is not wired up, at
least all the other features should be made available and when using
this specific routine, the "unknown" should point the user/developer to
the need to wire this up on this particular hardware architecture.

0d1472cdac perf script: Fix brstackinsn for AUXTRACE
[ Upstream commit 0cd032d3b5fcebf5454315400ab310746a81ca53 ]

brstackinsn must be allowed to be set by the user when AUX area data has
been captured because, in that case, the branch stack might be
synthesized on the fly. This fixes the following error:

Before:

  $ perf record -e '{intel_pt//,cpu/mem_inst_retired.all_loads,aux-sample-size=8192/pp}:u' grep -rqs jhgjhg /boot
  [ perf record: Woken up 19 times to write data ]
  [ perf record: Captured and wrote 2.274 MB perf.data ]
  $ perf script -F +brstackinsn --xed --itrace=i1usl100 | head
  Display of branch stack assembler requested, but non all-branch filter set
  Hint: run 'perf record -b ...'

After:

  $ perf record -e '{intel_pt//,cpu/mem_inst_retired.all_loads,aux-sample-size=8192/pp}:u' grep -rqs jhgjhg /boot
  [ perf record: Woken up 19 times to write data ]

ecfb25a7b1 perf probe: Fix to show function entry line as probe-able
commit 91e2f539eeda26ab00bd03fae8dc434c128c85ed upstream.

Fix die_walk_lines() to list the function entry line correctly.  Since
the dwarf_entrypc() does not return the entry pc if the DIE has only
range attribute, __die_walk_funclines() fails to list the declaration
line (entry line) in that case.

To solve this issue, this introduces die_entrypc() which correctly
returns the entry PC (the first address range) even if the DIE has only
range attribute. With this fix die_walk_lines() shows the function entry
line is able to probe correctly.

be9550ceb6 x86/insn: Add some Intel instructions to the opcode map
[ Upstream commit b980be189c9badba50634671e2303e92bf28e35a ]

Add to the opcode map the following instructions:
        cldemote
        tpause
        umonitor
        umwait
        movdiri
        movdir64b

        encls
        enclu
        enclv
        pconfig
        wbnoinvd

For information about the instructions, refer Intel SDM May 2019
(325462-070US) and Intel Architecture Instruction Set Extensions
May 2019 (319433-037).

The instruction decoding can be tested using the perf tools'

64b99a9205 perf probe: Filter out instances except for inlined subroutine and subprogram
[ Upstream commit da6cb952a89efe24bb76c4971370d485737a2d85 ]

Filter out instances except for inlined_subroutine and subprogram DIE in
die_walk_instances() and die_is_func_instance().

This fixes an issue that perf probe sets some probes on calling address
instead of a target function itself.

When perf probe walks on instances of an abstruct origin (a kind of
function prototype of inlined function), die_walk_instances() can also
pass a GNU_call_site (a GNU extension for call site) to callback. Since
it is not an inlined instance of target function, we have to filter out
when searching a probe point.

Without this patch, perf probe sets probes on call site address too.This
can happen on some function which is marked "inlined", but has actual
symbol. (I'm not sure why GCC mark it "inlined"):

  # perf probe -D vfs_read
  p:probe/vfs_read _text+2500017
  p:probe/vfs_read_1 _text+2499468
  p:probe/vfs_read_2 _text+2499563
  p:probe/vfs_read_3 _text+2498876
  p:probe/vfs_read_4 _text+2498512
  p:probe/vfs_read_5 _text+2498627

With this patch:

Slightly different results, similar tho:

  # perf probe -D vfs_read
  p:probe/vfs_read _text+2498512

Committer testing:

  # uname -a
  Linux quaco 5.3.8-200.fc30.x86_64 #1 SMP Tue Oct 29 14:46:22 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux

Before:

  # perf probe -D vfs_read
  p:probe/vfs_read _text+3131557
  p:probe/vfs_read_1 _text+3130975
  p:probe/vfs_read_2 _text+3131047

  #

After:

  # perf probe -D vfs_read
  p:probe/vfs_read _text+3130000

[ Upstream commit f4d99bdfd124823a81878b44b5e8750b97f73902 ]

Skip end-of-sequence and non-statement lines while walking through lines
list.

The "end-of-sequence" line information means:

 "the current address is that of the first byte after the
  end of a sequence of target machine instructions."
 (DWARF version 4 spec 6.2.2)

This actually means out of scope and we can not probe on it.

On the other hand, the statement lines (is_stmt) means:

 "the current instruction is a recommended breakpoint location.
  A recommended breakpoint location is intended to “represent”
  a line, a statement and/or a semantically distinct subpart
  of a statement."

 (DWARF version 4 spec 6.2.2)

So, non-statement line info also should be skipped.

These can reduce unneeded probe points and also avoid an error.

E.g. without this patch:

  # perf probe -a "clear_tasks_mm_cpumask:1"
  Added new events:
    probe:clear_tasks_mm_cpumask (on clear_tasks_mm_cpumask:1)
    probe:clear_tasks_mm_cpumask_1 (on clear_tasks_mm_cpumask:1)
    probe:clear_tasks_mm_cpumask_2 (on clear_tasks_mm_cpumask:1)
    probe:clear_tasks_mm_cpumask_3 (on clear_tasks_mm_cpumask:1)
    probe:clear_tasks_mm_cpumask_4 (on clear_tasks_mm_cpumask:1)

  You can now use it in all perf tools, such as:

  	perf record -e probe:clear_tasks_mm_cpumask_4 -aR sleep 1

  #

This puts 5 probes on one line, but acutally it's not inlined function.
This is because there are many non statement instructions at the
function prologue.

With this patch:

  # perf probe -a "clear_tasks_mm_cpumask:1"
  Added new event:
    probe:clear_tasks_mm_cpumask (on clear_tasks_mm_cpumask:1)

  You can now use it in all perf tools, such as:

  	perf record -e probe:clear_tasks_mm_cpumask -aR sleep 1

  #

Now perf-probe skips unneeded addresses.

Committer testing:

Slightly different results, but similar:

bde50714e8 perf probe: Fix to show calling lines of inlined functions
[ Upstream commit 86c0bf8539e7f46d91bd105e55eda96e0064caef ]

Fix to show calling lines of inlined functions (where an inline function
is called).

die_walk_lines() filtered out the lines inside inlined functions based
on the address. However this also filtered out the lines which call
those inlined functions from the target function.

To solve this issue, check the call_file and call_line attributes and do
not filter out if it matches to the line information.

Without this fix, perf probe -L doesn't show some lines correctly.
(don't see the lines after 17)

  # perf probe -L vfs_read

763127e5b3 perf probe: Return a better scope DIE if there is no best scope
[ Upstream commit c701636aeec4c173208697d68da6e4271125564b ]

Make find_best_scope() returns innermost DIE at given address if there
is no best matched scope DIE. Since Gcc sometimes generates intuitively
strange line info which is out of inlined function address range, we
need this fixup.

Without this, sometimes perf probe failed to probe on a line inside an
inlined function:

  # perf probe -D ksys_open:3
  Failed to find scope of probe point.
    Error: Failed to add events.

With this fix, 'perf probe' can probe it:

  # perf probe -D ksys_open:3
  p:probe/ksys_open _text+25707308
  p:probe/ksys_open_1 _text+25710596

9e3282b92b perf probe: Skip overlapped location on searching variables
[ Upstream commit dee36a2abb67c175265d49b9a8c7dfa564463d9a ]

Since debuginfo__find_probes() callback function can be called with  the
location which already passed, the callback function must filter out
such overlapped locations.

add_probe_trace_event() has already done it by commit 1a375ae7659a
("perf probe: Skip same probe address for a given line"), but
add_available_vars() doesn't. Thus perf probe -v shows same address
repeatedly as below:

  # perf probe -V vfs_read:18
  Available variables at vfs_read:18
          @<vfs_read+217>
                  char*   buf
                  loff_t* pos
                  ssize_t ret
                  struct file*    file
          @<vfs_read+217>
                  char*   buf
                  loff_t* pos
                  ssize_t ret
                  struct file*    file
          @<vfs_read+226>
                  char*   buf
                  loff_t* pos
                  ssize_t ret
                  struct file*    file

With this fix, perf probe -V shows it correctly:

  # perf probe -V vfs_read:18
  Available variables at vfs_read:18
          @<vfs_read+217>
                  char*   buf
                  loff_t* pos
                  ssize_t ret
                  struct file*    file
          @<vfs_read+226>
                  char*   buf
                  loff_t* pos
                  ssize_t ret
                  struct file*    file

528850352e perf probe: Fix to probe a function which has no entry pc
[ Upstream commit 5d16dbcc311d91267ddb45c6da4f187be320ecee ]

Fix 'perf probe' to probe a function which has no entry pc or low pc but
only has ranges attribute.

probe_point_search_cb() uses dwarf_entrypc() to get the probe address,
but that doesn't work for the function DIE which has only ranges
attribute. Use die_entrypc() instead.

Without this fix:

  # perf probe -k ../build-x86_64/vmlinux -D clear_tasks_mm_cpumask:0
  Probe point 'clear_tasks_mm_cpumask' not found.
    Error: Failed to add events.

With this:

  # perf probe -k ../build-x86_64/vmlinux -D clear_tasks_mm_cpumask:0
  p:probe/clear_tasks_mm_cpumask clear_tasks_mm_cpumask+0

Committer testing:

Before:

  [root@quaco ~]# perf probe clear_tasks_mm_cpumask:0
  Probe point 'clear_tasks_mm_cpumask' not found.
    Error: Failed to add events.
  [root@quaco ~]#

After:

  [root@quaco ~]# perf probe clear_tasks_mm_cpumask:0
  Added new event:
    probe:clear_tasks_mm_cpumask (on clear_tasks_mm_cpumask)

  You can now use it in all perf tools, such as:

  	perf record -e probe:clear_tasks_mm_cpumask -aR sleep 1

  [root@quaco ~]#

Using it with 'perf trace':

  [root@quaco ~]# perf trace -e probe:clear_tasks_mm_cpumask

Fix perf probe to probe an inlne function which has no entry pc
or low pc but only has ranges attribute.

This seems very rare case, but I could find a few examples, as
same as probe_point_search_cb(), use die_entrypc() to get the
entry address in probe_point_inline_cb() too.

097f5dfa9f perf probe: Walk function lines in lexical blocks
[ Upstream commit acb6a7047ac2146b723fef69ee1ab6b7143546bf ]

Since some inlined functions are in lexical blocks of given function, we
have to recursively walk through the DIE tree.  Without this fix,
perf-probe -L can miss the inlined functions which is in a lexical block
(like if (..) { func() } case.)

However, even though, to walk the lines in a given function, we don't
need to follow the children DIE of inlined functions because those do
not have any lines in the specified function.

We need to walk though whole trees only if we walk all lines in a given
file, because an inlined function can include another inlined function
in the same file.

[ Upstream commit 3895534dd78f0fd4d3f9e05ee52b9cdd444a743e ]

Since debuginfo__find_probe_point() uses dwarf_entrypc() for finding the

function DIE has only ranges attribute.

To fix this issue, use die_entrypc() instead of dwarf_entrypc().

lead to potentially misleading error messages. Instead, explicitly store

c761b5edde perf tests: Disable bp_signal testing for arm64
[ Upstream commit 6a5f3d94cb69a185b921cb92c39888dc31009acb ]

As there are several discussions for enabling perf breakpoint signal
testing on arm64 platform: arm64 needs to rely on single-step to execute
the breakpointed instruction and then reinstall the breakpoint exception
handler.  But if we hook the breakpoint with a signal, the signal
handler will do the stepping rather than the breakpointed instruction,
this causes infinite loops as below:

         Kernel space              |            Userspace
  ---------------------------------|--------------------------------
                                   |  __test_function() -> hit
				   |                       breakpoint
  breakpoint_handler()             |
    `-> user_enable_single_step()  |
  do_signal()                      |
                                   |  sig_handler() -> Step one
				   |                instruction and
				   |                trap to kernel
  single_step_handler()            |
    `-> reinstall_suspended_bps()  |
                                   |  __test_function() -> hit
				   |     breakpoint again and
				   |     repeat up flow infinitely

As Will Deacon mentioned [1]: "that we require the overflow handler to
do the stepping on arm/arm64, which is relied upon by GDB/ptrace. The
hw_breakpoint code is a complete disaster so my preference would be to
rip out the perf part and just implement something directly in ptrace,
but it's a pretty horrible job".  Though Will commented this on arm
architecture, but the comment also can apply on arm64 architecture.

For complete information, I searched online and found a few years back,
Wang Nan sent one patch 'arm64: Store breakpoint single step state into
pstate' [2]; the patch tried to resolve this issue by avoiding single
stepping in signal handler and defer to enable the signal stepping when
return to __test_function().  The fixing was not merged due to the
concern for missing to handle different usage cases.

Based on the info, the most feasible way is to skip Perf breakpoint
signal testing for arm64 and this could avoid the duplicate
investigation efforts when people see the failure.  This patch skips
this case on arm64 platform, which is same with arm architecture.

We received a user report that call-graph DWARF mode was enabled in
'perf record' but 'perf report' didn't unwind the callstack correctly.
The reason was, libunwind was not compiled in.

We can use 'perf -vv' to check the compiled libraries but it would be
valuable to report a warning to user directly (especially valuable for
a perf newbie).

The warning is:

It will be cut anyway, but compiler generates truncation warns like:

In order to avoid warns, lets decrease buf size for cgroup workdir on
24 bytes with assumption to include also "/cgroup.subtree_control" to
the address. The cut will never happen anyway.

2dfbfb88b0 selftests: forwarding: Delete IPv6 address at the end
[ Upstream commit 65cb13986229cec02635a1ecbcd1e2dd18353201 ]

When creating the second host in h2_create(), two addresses are assigned
to the interface, but only one is deleted. When running the test twice
in a row the following error is observed:

$ ./router_bridge_vlan.sh
TEST: ping                                                          [ OK ]
TEST: ping6                                                         [ OK ]
TEST: vlan                                                          [ OK ]
$ ./router_bridge_vlan.sh
RTNETLINK answers: File exists
TEST: ping                                                          [ OK ]
TEST: ping6                                                         [ OK ]
TEST: vlan                                                          [ OK ]

Fix this by deleting the address during cleanup.

484c4d9a9c perf script: Fix invalid LBR/binary mismatch error
[ Upstream commit 5172672da02e483d9b3c4d814c3482d0c8ffb1a6 ]

The 'len' returned by grab_bb() includes an extra MAXINSN bytes to allow
for the last instruction, so the the final 'offs' will not be 'len'.
Fix the error condition logic accordingly.

043a7151d2 tools/bpf: make libbpf _GNU_SOURCE friendly
[ Upstream commit b42699547fc9fb1057795bccc21a6445743a7fde ]

During porting libbpf to bcc, I got some warnings like below:
  ...
  [  2%] Building C object src/cc/CMakeFiles/bpf-shared.dir/libbpf/src/libbpf.c.o
  /home/yhs/work/bcc2/src/cc/libbpf/src/libbpf.c:12:0:

  warning: assignment makes integer from pointer without a cast [enabled by default]
     ret = strerror_r(err, buf, size);
  ...

bcc is built with _GNU_SOURCE defined and this caused the above warning.
This patch intends to make libpf _GNU_SOURCE friendly by
  . define _GNU_SOURCE in libbpf.c unless it is not defined
  . undefine _GNU_SOURCE as non-gnu version of strerror_r is expected.

29e704b7a7 tools: bpftool: fix a bitfield pretty print issue
[ Upstream commit 528bff0cdb6649f97f2c4802e4ac7a4b50645f2f ]

Commit b12d6ec097 ("bpf: btf: add btf print functionality")
added btf pretty print functionality to bpftool.
There is a problem though in printing a bitfield whose type
has modifiers.

For example, for a type like
  typedef int ___int;
  struct tmp_t {
          int a:3;
          ___int b:3;
  };
Suppose we have a map
  struct bpf_map_def SEC("maps") tmpmap = {
          .type = BPF_MAP_TYPE_HASH,
          .key_size = sizeof(__u32),
          .value_size = sizeof(struct tmp_t),
          .max_entries = 1,
  };
and the hash table is populated with one element with
key 0 and value (.a = 1 and .b = 2).

In BTF, the struct member "b" will have a type "typedef" which
points to an int type. The current implementation does not
pass the bit offset during transition from typedef to int type,
hence incorrectly print the value as
  $ bpftool m d id 79
  [{
          "key": 0,
          "value": {
              "a": 0x1,
              "b": 0x1
          }
      }
  ]

This patch fixed the issue by carrying bit_offset along the type
chain during bit_field print. The correct result can be printed as
  $ bpftool m d id 76
  [{
          "key": 0,
          "value": {
              "a": 0x1,
              "b": 0x2
          }
      }
  ]

The kernel pretty print is implemented correctly and does not
have this issue.

5aba77393e selftests/powerpc: Skip test instead of failing
[ Upstream commit eafcd8e3fbad4f426a40ed2b6a8c697c3a4ef36a ]

Current core-pkey selftest fails if the test runs without privileges to
write into the core pattern file (/proc/sys/kernel/core_pattern). This
causes the test to fail and give the impression that the subsystem being
tested is broken, when, in fact, the test is being executed without the
proper privileges. This is the current error:

	test: core_pkey
	tags: git_version:v4.19-3-g9e3363be9bce-dirty
	Error writing to core_pattern file: Permission denied
	failure: core_pkey

This patch simply skips this test if it runs without the proper privileges,
avoiding this undesired failure.

104d0d63a1 selftests/powerpc: Allocate base registers
[ Upstream commit 5249497a7bb6334fcc128588d6a7e1e21786515a ]

Some ptrace selftests are passing input operands using a constraint that
can allocate any register for the operand, and using these registers on
load/store operations.

If the register allocated by the compiler happens to be zero (r0), it might
cause an invalid memory address access, since load and store operations
consider the content of 0x0 address if the base register is r0, instead of
the content of the r0 register. For example:

	r1 := 0xdeadbeef
	r0 := 0xdeadbeef

	ld r2, 0(1) /* will load into r2 the content of r1 address */
	ld r2, 0(0) /* will load into r2 the content of 0x0 */

In order to avoid this possible problem, the inline assembly constraint
should be aware that these registers will be used as a base register, thus,
r0 should not be allocated.

Other than that, this patch removes inline assembly operands that are not
used by the tests.
