commit db2c549407d4a76563c579e4768f7d6d32afefba upstream.
This patch fixes an off-by-one error in strncpy size argument in
tools/perf/util/map.c. The issue is that in:
strncmp(filename, "/system/lib/", 11)
the passed string literal: "/system/lib/" has 12 bytes (without the NULL
byte) and the passed size argument is 11. As a result, the logic won't
match the ending "/" byte and will pass filepaths that are stored in
other directories e.g. "/system/libmalicious/bin" or just
"/system/libmalicious".
This functionality seems to be present only on Android. I assume the
/system/ directory is only writable by the root user, so I don't think
this bug has much (or any) security impact.
Fixes: eca818369996 ("perf tools: Add automatic remapping of Android libraries")

[ Upstream commit be40920fbf1003c38ccdc02b571e01a75d890c82 ]
When I tried to compile tools/perf from the top directory with the -C
option, the O= option didn't work correctly if I passed a relative path:
$ make O=BUILD -C tools/perf/
make: Entering directory '/home/mhiramat/ksrc/linux/tools/perf'
BUILD: Doing 'make -j8' parallel build
../scripts/Makefile.include:4: *** O=/home/mhiramat/ksrc/linux/tools/perf/BUILD does not exist. Stop.
make: *** [Makefile:70: all] Error 2
make: Leaving directory '/home/mhiramat/ksrc/linux/tools/perf'
The O= directory existence check failed because the check script ran in
the build target directory instead of the directory where I ran the make
command.
To fix that, once change directory to $(PWD) and check O= directory,
since the PWD is set to where the make command runs.
Fixes: c883122acc0d ("perf tools: Let O= makes handle relative paths")

commit 1efde2754275dbd9d11c6e0132a4f09facf297ab upstream.
Do not depend on dwfl_module_addrsym() because it can fail on user-space
shared libraries.
Actually, same bug was fixed by commit 664fee3dc379 ("perf probe: Do not
use dwfl_module_addrsym if dwarf_diename finds symbol name"), but commit
07d369857808 ("perf probe: Fix wrong address verification) reverted to
get actual symbol address from symtab.
This fixes it again by getting symbol address from DIE, and only if the
DIE has only address range, it uses dwfl_module_addrsym().

[ Upstream commit 585c91f40d201bc564d4e76b83c05b3b5363fe7e ]
Fix unsafe unaligned pointer usage in usbip network interfaces. usbip tool
build fails with new gcc -Werror=address-of-packed-member checks.
usbip_network.c: In function ‘usbip_net_pack_usb_device’:
usbip_network.c:79:32: error: taking address of packed member of ‘struct usbip_usb_device’ may result in an unaligned pointer value [-Werror=address-of-packed-member]
79 | usbip_net_pack_uint32_t(pack, &udev->busnum);
Fix with minor changes to pass by value instead of by address.

[ Upstream commit 6794200fa3c9c3e6759dae099145f23e4310f4f7 ]
GCC9 introduced string hardening mechanisms, which exhibits the error
during fs api compilation:
error: '__builtin_strncpy' specified bound 4096 equals destination size
[-Werror=stringop-truncation]
This comes when the length of copy passed to strncpy is is equal to
destination size, which could potentially lead to buffer overflow.
There is a need to mitigate this potential issue by limiting the size of
destination by 1 and explicitly terminate the destination with NULL.

commit 07d369857808b7e8e471bbbbb0074a6718f89b31 upstream.
Since there are some DIE which has only ranges instead of the
combination of entrypc/highpc, address verification must use
dwarf_haspc() instead of dwarf_entrypc/dwarf_highpc.
Also, the ranges only DIE will have a partial code in different section
(e.g. unlikely code will be in text.unlikely as "FUNC.cold" symbol). In
that case, we can not use dwarf_entrypc() or die_entrypc(), because the
offset from original DIE can be a minus value.
Instead, this simply gets the symbol and offset from symtab.
Without this patch;
# perf probe -D clear_tasks_mm_cpumask:1
Failed to get entry address of clear_tasks_mm_cpumask
Error: Failed to add events.
And with this patch:
# perf probe -D clear_tasks_mm_cpumask:1
p:probe/clear_tasks_mm_cpumask clear_tasks_mm_cpumask+0
p:probe/clear_tasks_mm_cpumask_1 clear_tasks_mm_cpumask+5
p:probe/clear_tasks_mm_cpumask_2 clear_tasks_mm_cpumask+8
p:probe/clear_tasks_mm_cpumask_3 clear_tasks_mm_cpumask+16
p:probe/clear_tasks_mm_cpumask_4 clear_tasks_mm_cpumask+82
Committer testing:
I managed to reproduce the above:
[root@quaco ~]# perf probe -D clear_tasks_mm_cpumask:1
p:probe/clear_tasks_mm_cpumask _text+919968
p:probe/clear_tasks_mm_cpumask_1 _text+919973
p:probe/clear_tasks_mm_cpumask_2 _text+919976
[root@quaco ~]#
But then when trying to actually put the probe in place, it fails if I
use :0 as the offset:
[root@quaco ~]# perf probe -L clear_tasks_mm_cpumask | head -5
<clear_tasks_mm_cpumask@/usr/src/debug/kernel-5.2.fc30/linux-5.2.18-200.fc30.x86_64/kernel/cpu.c:0>
0 void clear_tasks_mm_cpumask(int cpu)
1 {
2 struct task_struct *p;
[root@quaco ~]# perf probe clear_tasks_mm_cpumask:0
Probe point 'clear_tasks_mm_cpumask' not found.
Error: Failed to add events.
[root@quaco
The next patch is needed to fix this case.

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.

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.

[ 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

[ 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.

[ 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

15 ret = __vfs_read(file, buf, count, pos);

[ 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
p:probe/ksys_open_2 _text+25711114

[ 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

[ 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.

In some case, a function instance can be made without any low PC or

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:

commit 700c1018b86d0d4b3f1f2d459708c0cdf42b521d upstream.
gawk 5.0.1 generates the following regexp warnings:
GEN /home/sasha/torvalds/tools/objtool/arch/x86/lib/inat-tables.c
awk: ../arch/x86/tools/gen-insn-attr-x86.awk:260: warning: regexp escape sequence `\:' is not a known regexp operator
awk: ../arch/x86/tools/gen-insn-attr-x86.awk:350: (FILENAME=../arch/x86/lib/x86-opcode-map.txt FNR=41) warning: regexp escape sequence `\&' is not a known regexp operator
Ealier versions of gawk are not known to generate these warnings. The
gawk manual referenced below does not list characters ':' and '&' as
needing escaping, so 'unescape' them. See
https://www.gnu.org/software/gawk/manual/html_node/Escape-Sequences.html
for more info.
Running diff on the output generated by the script before and after
applying the patch reported no differences.

[ Upstream commit 2452c96e617a0ff6fb2692e55217a3fa57a7322c ]
Test $comm in kprobe-event argument syntax testcase
only if it is supported on the kernel because
$comm has been introduced 4.8 kernel.
So on older stable kernel, it should be skipped.

commit 722ddfde366fd46205456a9c5ff9b3359dc9a75e upstream.
The final sort might get confused when the comparison is done over
bigger numbers than int like for -s time.
Check the following report for longer workloads:
$ perf report -s time -F time,overhead --stdio
Fix hist_entry__sort() to properly return int64_t and not possible cut
int.
Fixes: 043ca389a318 ("perf tools: Use hpp formats to sort final output")

[ Upstream commit 1abecfcaa7bba21c9985e0136fa49836164dd8fd ]
The memory @orig_flags is allocated by strdup(), it is freed on the
normal path, but leak to free on the error path.
Fix this by adding free(orig_flags) on the error path.

[ Upstream commit ee212d6ea20887c0ef352be8563ca13dbf965906 ]
Whenever an mmap/mmap2 event occurs, the map tree must be updated to add a new
entry. If a new map overlaps a previous map, the overlapped section of the
previous map is effectively unmapped, but the non-overlapping sections are
still valid.
maps__fixup_overlappings() is responsible for creating any new map entries from
the previously overlapped map. It optionally creates a before and an after map.
When creating the after map the existing code failed to adjust the map.pgoff.
This meant the new after map would incorrectly calculate the file offset
for the ip. This results in incorrect symbol name resolution for any ip in the
after region.
Make maps__fixup_overlappings() correctly populate map.pgoff.
Add an assert that new mapping matches old mapping at the beginning of
the after map.
Committer-testing:
Validated correct parsing of libcoreclr.so symbols from .NET Core 3.0 preview9
(which didn't strip symbols).
Preparation:
~/dotnet3.0-preview9/dotnet new webapi -o perfSymbol
cd perfSymbol

commit 7d4c85b7035eb2f9ab217ce649dcd1bfaf0cacd3 upstream.
The 'test_dir' variable is assigned to the 'release' array which is
out-of-scope 3 lines later.
Extend the scope of the 'release' array so that an out-of-scope array
isn't accessed.
Bug detected by clang's address sanitizer.

[ Upstream commit 443f2d5ba13d65ccfd879460f77941875159d154 ]
Observe a segmentation fault when 'perf stat' is asked to repeat forever
with the interval option.
Without fix:
# perf stat -r 0 -I 5000 -e cycles -a sleep 10
# time counts unit events
5.000211692 3,13,89,82,34,157 cycles
10.000380119 1,53,98,52,22,294 cycles
10.040467280 17,16,79,265 cycles
Segmentation fault
This problem was only observed when we use forever option aka -r 0 and
works with limited repeats. Calling print_counter with ts being set to
NULL, is not a correct option when interval is set. Hence avoid
print_counter(NULL,..) if interval is set.
With fix:
# perf stat -r 0 -I 5000 -e cycles -a sleep 10
# time counts unit events
5.019866622 3,15,14,43,08,697 cycles

Committer notes:
Did the 'git bisect' to find the cset introducing the problem to add the
Fixes tag below, and at that time the problem reproduced as:
(gdb) run stat -r0 -I500 sleep 1

Program received signal SIGSEGV, Segmentation fault.
