perf lock: Don't free "lock_seq_stat" if read_count isn't zero
When execute command "perf lock report", it hits failure and outputs log
as follows:
perf: builtin-lock.c:623: report_lock_release_event: Assertion `!(seq->read_count < 0)' failed.
Aborted
This is an imbalance issue. The locking sequence structure
"lock_seq_stat" contains the reader counter and it is used to check if
the locking sequence is balance or not between acquiring and releasing.
If the tool wrongly frees "lock_seq_stat" when "read_count" isn't zero,
the "read_count" will be reset to zero when allocate a new structure at
the next time; thus it causes the wrong counting for reader and finally
results in imbalance issue.
To fix this issue, if detects "read_count" is not zero (means still have
read user in the locking sequence), goto the "end" tag to skip freeing
structure "lock_seq_stat".

perf lock: Correct field name "flags"
The tracepoint "lock:lock_acquire" contains field "flags" but not
"flag". Current code wrongly retrieves value from field "flag" and it
always gets zero for the value, thus "perf lock" doesn't report the
correct result.
This patch replaces the field name "flag" with "flags", so can read out
the correct flags for locking.

KVM: selftests: allow two iterations of dirty_log_perf_test
Even though one iteration is not enough for the dirty log performance test (due to the cost of building page tables, zeroing memory etc.) two is okay and it is the default.

KVM: selftests: Introduce the dirty log perf test
The dirty log perf test will time verious dirty logging operations (enabling dirty logging, dirtying memory, getting the dirty log, clearing the dirty log, and disabling dirty logging) in order to quantify dirty logging performance.

KVM: selftests: Remove address rounding in guest code
Rounding the address the guest writes to a host page boundary will only have an effect if the host page size is larger than the guest page size, but in that case the guest write would still go to the same host page.

Networking fixes for 5.10-rc3, including fixes from wireless, can,
and netfilter subtrees.
Current release - bugs in new features:
- can: isotp: isotp_rcv_cf(): enable RX timeout handling in
listen-only mode
Previous release - regressions:
- mac80211:
- don't require VHT elements for HE on 2.4 GHz
- fix regression where EAPOL frames were sent in plaintext
- netfilter:
- ipset: Update byte and packet counters regardless of whether
they match
- ip_tunnel: fix over-mtu packet send by allowing fragmenting even
if inner packet has IP_DF (don't fragment) set in its header
(when TUNNEL_DONT_FRAGMENT flag is not set on the tunnel dev)
- net: fec: fix MDIO probing for some FEC hardware blocks
- ip6_tunnel: set inner ipproto before ip6_tnl_encap to un-break
gso support
- sctp: Fix COMM_LOST/CANT_STR_ASSOC err reporting on big-endian
platforms, sparse-related fix used the wrong integer size
Previous release - always broken:
- netfilter: use actual socket sk rather than skb sk when routing
harder
- r8169: work around short packet hw bug on RTL8125 by padding frames
- net: ethernet: ti: cpsw: disable PTPv1 hw timestamping
advertisement, the hardware does not support it
- chelsio/chtls: fix always leaking ctrl_skb and another leak caused
by a race condition
- fix drivers incorrectly writing into skbs on TX:
- cadence: force nonlinear buffers to be cloned
- gianfar: Account for Tx PTP timestamp in the skb headroom
- gianfar: Replace skb_realloc_headroom with skb_cow_head for PTP
- can: flexcan:
- remove FLEXCAN_QUIRK_DISABLE_MECR quirk for LS1021A
- add ECC initialization for VF610 and LX2160A
- flexcan_remove(): disable wakeup completely
- can: fix packet echo functionality:
- peak_canfd: fix echo management when loopback is on
- make sure skbs are not freed in IRQ context in case they need
to be dropped
- always clone the skbs to make sure they have a reference on
the socket, and prevent it from disappearing
- fix real payload length return value for RTR frames
- can: j1939: return failure on bind if netdev is down, rather than
waiting indefinitely
Misc:
- IPv6: reply ICMP error if the first fragment don't include all
headers to improve compliance with RFC 8200

inner packet has IP_DF (don't fragment) set in its header (when
TUNNEL_DONT_FRAGMENT flag is not set on the tunnel dev)
- net: fec: fix MDIO probing for some FEC hardware blocks
- ip6_tunnel: set inner ipproto before ip6_tnl_encap to un-break gso
support
- sctp: Fix COMM_LOST/CANT_STR_ASSOC err reporting on big-endian
platforms, sparse-related fix used the wrong integer size
Previous releases - always broken:
- netfilter: use actual socket sk rather than skb sk when routing
harder
- r8169: work around short packet hw bug on RTL8125 by padding frames
- net: ethernet: ti: cpsw: disable PTPv1 hw timestamping
advertisement, the hardware does not support it
- chelsio/chtls: fix always leaking ctrl_skb and another leak caused
by a race condition
- fix drivers incorrectly writing into skbs on TX:
- cadence: force nonlinear buffers to be cloned
- gianfar: Account for Tx PTP timestamp in the skb headroom
- gianfar: Replace skb_realloc_headroom with skb_cow_head for PTP
- can: flexcan:
- remove FLEXCAN_QUIRK_DISABLE_MECR quirk for LS1021A
- add ECC initialization for VF610 and LX2160A
- flexcan_remove(): disable wakeup completely
- can: fix packet echo functionality:
- peak_canfd: fix echo management when loopback is on
- make sure skbs are not freed in IRQ context in case they need to
be dropped
- always clone the skbs to make sure they have a reference on the
socket, and prevent it from disappearing
- fix real payload length return value for RTR frames
- can: j1939: return failure on bind if netdev is down, rather than
waiting indefinitely
Misc:
- IPv6: reply ICMP error if the first fragment don't include all
headers to improve compliance with RFC 8200"

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.

This pull contains a series of warning fixes from Mauro; once applied, the
number of warnings from the once-noisy docs build process is nearly zero. Getting to this point has required a lot of work; once there, hopefully we can keep things that way. I have packaged this as a separate pull because it does a fair amount of reaching outside of Documentation/. The changes are all in comments and in code placement. It's all been in linux-next since last week. -----BEGIN PGP SIGNATURE----- iQFDBAABCAAtFiEEIw+MvkEiF49krdp9F0NaE2wMflgFAl+hscQPHGNvcmJldEBs d24ubmV0AAoJEBdDWhNsDH5YgZAH/0JeDA/1VLZYYTmdABz8mjBZsoW9tyPGGztF nsh5ykdHhL3MeTRwumW5armLVrfKhd1XT+nIzD7OcWlqu+RDOvQ5I95rahr473hP 1SHTjqm3/AlJwQoeS72X5U6QEJQ58e2IwCbP23H3x7I3Q3snEA/HhswzxurfoB/Z j81YzDV2YPEc0LJWZ5Vn0NEdwP8cdpFv5rojsQmepq7K0yJ7tEHb7/u2cEuUBgXS 8LcYCNPLpiN+q5N8uQ5oDjIUNdLQvP03kgKtQWiCTr4BRydOrDlJie28LIedamEz anu7UfaVK4bxn+ugRI0g2+aWQKux81ULCinKUWmLRNbcxjhaQqQ= =hDfp -----END PGP SIGNATURE----- Merge tag 'docs-5.10-warnings' of git://git.lwn.net/linux Pull documentation build warning fixes from Jonathan Corbet: "This contains a series of warning fixes from Mauro; once applied, the number of warnings from the once-noisy docs build process is nearly zero.

perf hists browser: Increase size of 'buf' in perf_evsel__hists_browse()
Making perf with gcc-9.1.1 generates the following warning:

IOW, the string in line 3078 might be too long for buf[] of 64 bytes.
Fix this by increasing the size of buf[] to 128.

tools kvm headers: Update KVM headers from the kernel sources
Some should cause changes in tooling, like the one adding LAST_EXCP, but the way it is structured end up not making that happen. The new SVM_EXIT_INVPCID should get used by arch/x86/util/kvm-stat.c, in the svm_exit_reasons table. The tools/perf/trace/beauty part has scripts to catch changes and automagically create tables, like tools/perf/trace/beauty/kvm_ioctl.sh, but changes are needed to make tools/perf/arch/x86/util/kvm-stat.c catch those automatically. These were handled by the existing scripts: $ tools/perf/trace/beauty/kvm_ioctl.sh > before $ cp include/uapi/linux/kvm.h tools/include/uapi/linux/kvm.h $ tools/perf/trace/beauty/kvm_ioctl.sh > after $ diff -u before after --- before 2020-11-03 08:43:52.910728608 -0300 +++ after 2020-11-03 08:44:04.273959984 -0300 @@ -89,6 +89,7 @@ [0xbf] = "SET_NESTED_STATE", [0xc0] = "CLEAR_DIRTY_LOG", [0xc1] = "GET_SUPPORTED_HV_CPUID", + [0xc6] = "X86_SET_MSR_FILTER", [0xe0] = "CREATE_DEVICE", [0xe1] = "SET_DEVICE_ATTR", [0xe2] = "GET_DEVICE_ATTR", $ $ tools/perf/trace/beauty/vhost_virtio_ioctl.sh > before $ cp include/uapi/linux/vhost.h tools/include/uapi/linux/vhost.h $ $ tools/perf/trace/beauty/vhost_virtio_ioctl.sh > after $ diff -u before after --- before 2020-11-03 08:45:55.522225198 -0300 +++ after 2020-11-03 08:46:12.881578666 -0300 @@ -37,4 +37,5 @@ [0x71] = "VDPA_GET_STATUS", [0x73] = "VDPA_GET_CONFIG", [0x76] = "VDPA_GET_VRING_NUM", + [0x78] = "VDPA_GET_IOVA_RANGE", }; $ This addresses these perf build warnings: Warning: Kernel ABI header at 'tools/arch/arm64/include/uapi/asm/kvm.h' differs from latest version at 'arch/arm64/include/uapi/asm/kvm.h' diff -u tools/arch/arm64/include/uapi/asm/kvm.h arch/arm64/include/uapi/asm/kvm.h Warning: Kernel ABI header at 'tools/arch/s390/include/uapi/asm/sie.h' differs from latest version at 'arch/s390/include/uapi/asm/sie.h' diff -u tools/arch/s390/include/uapi/asm/sie.h arch/s390/include/uapi/asm/sie.h Warning: Kernel ABI header at 'tools/arch/x86/include/uapi/asm/kvm.h' differs from latest version at 'arch/x86/include/uapi/asm/kvm.h' diff -u tools/arch/x86/include/uapi/asm/kvm.h arch/x86/include/uapi/asm/kvm.h Warning: Kernel ABI header at 'tools/arch/x86/include/uapi/asm/svm.h' differs from latest version at 'arch/x86/include/uapi/asm/svm.h' diff -u tools/arch/x86/include/uapi/asm/svm.h arch/x86/include/uapi/asm/svm.h Warning: Kernel ABI header at 'tools/include/uapi/linux/kvm.h' differs from latest version at 'include/uapi/linux/kvm.h' diff -u tools/include/uapi/linux/kvm.h include/uapi/linux/kvm.h Warning: Kernel ABI header at 'tools/include/uapi/linux/vhost.h' differs from latest version at 'include/uapi/linux/vhost.h' diff -u tools/include/uapi/linux/vhost.h include/uapi/linux/vhost.h Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: Alexander Yarygin <yarygin@linux.vnet.ibm.com> Cc: Borislav Petkov <bp@suse.de> Cc: Christian Borntraeger <borntraeger@de.ibm.com> Cc: Cornelia Huck <cornelia.huck@de.ibm.com> Cc: David Ahern <dsahern@gmail.com> Cc: Ian Rogers <irogers@google.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Joerg Roedel <jroedel@suse.de> Cc: Namhyung Kim <namhyung@kernel.org> Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> |

perf scripting python: Avoid declaring function pointers with a visibility attribute
To avoid this:
util/scripting-engines/trace-event-python.c: In function 'python_start_script':
util/scripting-engines/trace-event-python.c:1595:2: error: 'visibility' attribute ignored [-Werror=attributes]
1595 | PyMODINIT_FUNC (*initfunc)(void);
| ^~~~~~~~~~~~~~
That started breaking when building with PYTHON=python3 and these gcc
versions (I haven't checked with the clang ones, maybe it breaks there
as well):
# export PERF_TARBALL=http://192.168.86.5/perf/perf-5.9.0.tar.xz
# dm fedora:33 fedora:rawhide
1 107.80 fedora:33 : Ok gcc (GCC) 10.2.1 20201005 (Red Hat 10.2.1-5), clang version 11.0.0 (Fedora 11.0.0-1.fc33)
2 92.47 fedora:rawhide : Ok gcc (GCC) 10.2.1 20201016 (Red Hat 10.2.1-6), clang version 11.0.0 (Fedora 11.0.0-1.fc34)
#
Avoid that by ditching that 'initfunc' function pointer with its:
#define Py_EXPORTED_SYMBOL _attribute_ ((visibility ("default")))
#define PyMODINIT_FUNC Py_EXPORTED_SYMBOL PyObject*
And just call PyImport_AppendInittab() at the end of the ifdef python3
block with the functions that were being attributed to that initfunc.
