Subject: [PATCH] killsnoop: add missing -s and -T options to the synopsis
|
|
||||||
|
|
||||||
The -s option is missing from the synopsis of the killsnoop manpage,
|
|
||||||
example file and the comment on top of the tool itself.
|
|
||||||
Also, -T option is missing from the example file.

|
|

|
|
||||||
kernel commit abd4349ff9b8("mm: compaction: cleanup the compaction trace
|

|
|
||||||
migrate_pfn, free_pfn, end_pfn, sync) to (cc, start_pfn, end_pfn, sync),
|
|

Replacing RAW_TRACEPOINT_PROBE with TRACEPOINT_PROBE solves this problem

Subject: [PATCH] tools/deadlock: Add an option to set the maximum number of
|
|
||||||
stack traces
|
|
||||||
|
|
||||||
Commit 77f5252d ("tools/deadlock: support specifies maxnum of threads
|
|
||||||
and edge cases (#3455)") allow to set the maximum number of threads
|
|
||||||
and edge cases to be able to reduce the memory usage of the deadlock
|
|
||||||
tool. It however let the size of the map of stack traces fixed. It's
|
|
||||||
current size, 640k (actually rounded up to 1M) takes 1Gb of vmalloced
|
|
||||||
kernel memory.
|
|
||||||
|
|
||||||
This patch adds an option to make the maximum number of stack traces
|
|
||||||
user defined. It also set the default value to 64k, in line with the
|
|
||||||
current default for the number of edge cases and threads.
|
|
||||||
|
|
||||||
It fix the following issue on system with limited memory ressources:
|
|
||||||
could not open bpf map: stack_traces, error: Cannot allocate memory

Subject: [PATCH] tools/funcslower: fix printing of folded stacks
|
|
||||||
|
|
||||||
When trying to print folded stack, funcslower tries to join bytes to a
|
|
||||||
string. Let's perform that operation with bytes only, and decode
|
|
||||||
before printing.
|
|
||||||
Also, decode symbols name before printing for the default stack
|
|
||||||
format, to avoid unsightly b'xxx' output.
|
|
||||||
|
|
||||||
It fixes the following error:
|
|
||||||
|
|
||||||
Exception ignored on calling ctypes callback function: <function PerfEventArray._open_perf_buffer.<locals>.raw_cb_ at 0x7f200541e5e0>

Subject: [PATCH] tools/slabratetop: Fix error: incomplete definition of type
|
|
||||||
'struct slab'
|
|
||||||
|
|
||||||
kernel commit 40f3bf0cb04c("mm: Convert struct page to struct slab in functions
|
|
||||||
used by other subsystems") introduce slab_address() function, commit 6e48a966dfd1
|
|
||||||
("mm/kasan: Convert to struct folio and struct slab") linux/kasan.h adds a
|
|
||||||
dependency on the slab struct, This leads to the following problems:
|
|
||||||
|
|
||||||
$ sudo ./slabratetop.py
|
|
||||||
In file included from /virtual/main.c:13:
|
|
||||||

|
|
||||||

|
|
||||||

|
|
||||||

|
|
||||||

|
|
||||||
struct slab;
|
|
||||||
^
|
|
||||||
...
|
|
||||||
|
|
||||||
At first, I wanted to fix this with a kernel patch [1], however, bcc as a
|
|
||||||
downstream project of the kernel, this issue should be solved inside the bcc
|
|
||||||
project. This is agreed by kernel maintainer and bcc maintainer @yonghong-song.
|
|
||||||
|
|
||||||
This solution is provided by @yonghong-song [0].

Subject: [PATCH 2/4] Fixing pvalloc memleak test
|
||||||
|
|
||||||
|
Request to allocate 30K bytes using pvalloc(), results
|
||||||
|
in allocating 3*64Kb(on 64Kb pagesize system). The assertion
|
||||||
|
expects leak to be 30Kb, whereas leaked memory is much more
|
||||||
|
due to pvalloc's implementation for power.

Subject: [PATCH] libbpf-tools: add block_io_{start,done} tracepoints support
|
||||||
|
to bio tools
|
||||||
|
|
||||||
|
Some bio tools fail to kprobe blk_account_io_{start,done} after v5.17,
|
||||||
|
because they become inlined, see [0]. To fix this issue, tracepoints
|
||||||
|
blick_io_{start,done} are introcuded in kernel, see[1].
|
||||||
|
|
||||||
|
Update related bio tools to support new tracepoints, and also simplify
|
||||||
|
attach.
|
||||||
|
|
||||||
|
[0] Kernel commit 450b7879e345 (block: move blk_account_io_{start,done} to blk-mq.c)
|
||||||
|
[1] Kernel commit 5a80bd075f3b (block: introduce block_io_start/block_io_done tracepoints)

Subject: [PATCH] tools: Add support for the new block_io_* tracepoints
|
||||||
|
|
||||||
|
The bio tools currently depends on blk_account_io_done/start functions
|
||||||
|
that can be inlined. To fix that, a couple of tracepoints have been
|
||||||
|
added upstream (block:block_io_start/done). This patch add the support
|
||||||
|
for those tracepoints when they are available.
|
||||||
|
|
||||||
|
Unfortunately, the bio tools relies on data that is not available to
|
||||||
|
the tracepoints (mostly the struct request). So the tracepoints can't
|
||||||
|
be used as drop in replacement for blk_account_io_*. Main difference,
|
||||||
|
is that we can't use the struct request as the hash key anymore, so it
|
||||||
|
now uses the couple (dev_t, sector) for that purpose.
|
||||||
|
|
||||||
|
For the biolatency tool, the -F option is disabled when only the
|
||||||
|
tracepoints are available because the flags are not all accessible
|
||||||
|
from the tracepoints. Otherwise, all features of the tools should
|
||||||
|
remain.
|
||||||
|
|
||||||
|
Closes #4261

Subject: [PATCH 2/2] tools/tcpstates: fix IPv6 journal
|
||||||
|
|
||||||
|
When logging ipv6 state change, journal_fields tries to pack
|
||||||
|
event.addr and event.daddr, which is not an integer in this, to
|
||||||
|
present a bytes-like object to socket.inet_ntop. This can be fixed by
|
||||||
|
having a similar type for [sd]addr for IPv4 and IPv6. Making both an
|
||||||
|
array of u32 solves the issue by presenting a bytes-like object
|
||||||
|
directly to inet_ntop, without the need for the struct packing stage.
|
||||||
|
|
||||||
|
Also now, the similar behavior, makes it easier to factor code for
|
||||||
|
IPv4 and IPv6.
|
||||||
|
|
||||||
|
It solves the following error:

||||||

Subject: [PATCH 1/2] tools/tcpstates: fix context ptr modified error
|
||||||
|
|
||||||
|
Introduce local variable tcp_new_state,
|
||||||
|
to avoid llvm optimization of args->newstate,
|
||||||
|
which will cause context ptr args modified.
|
||||||
|
spilt event.ports to lport and dport.
|
||||||
|
switch type of TCP state from unsigned int to int.

Subject: [PATCH] tools/trace: don't raise an exception in a ctype callback
|
||||||
|
|
||||||
|
To exit the tool when the maximal number of event is reached (-M
|
||||||
|
option), the tool currently call exit(), which raise a SystemExit
|
||||||
|
exception. The handling of exception from ctype callback doesn't seem
|
||||||
|
straightforward and dependent on python version.
|
||||||
|
|
||||||
|
This patch avoid the issue altogether by using a global variable
|
||||||
|
instead.
|
||||||
|
|
||||||
|
Closes #3049
