perf/core improvements and fixes:
kernel:
Stephane Eranian :
- Restore mmap record type correctly when handling PERF_RECORD_MMAP2
events, as the same template is used for all the threads interested
in mmap events, some may want just PERF_RECORD_MMAP, while some
may want the extra info in MMAP2 records.
perf probe:
Adrian Hunter:
- Fix getting the kernel map, because since changes related to x86 PTI
entry trampolines handling, there are more than one kernel map.
perf script:
Andi Kleen:
- Support insn output for normal samples, i.e.:
perf script -F ip,sym,insn --xed
Will fetch the sample IP from the thread address space and feed it
to Intel's XED disassembler, producing lines such as:
ffffffffa4068804 native_write_msr wrmsr
ffffffffa415b95e __hrtimer_next_event_base movq 0x18(%rax), %rdx
That match 'perf annotate's output.
- Make the --cpu filter apply to PERF_RECORD_COMM/FORK/... events, in
addition to PERF_RECORD_SAMPLE.
perf report:
- Add a new --samples option to save a small random number of samples
per hist entry, using a reservoir technique to select a representative
number of samples.
Then allow browsing the samples using 'perf script' as part of the hist
entry context menu. This automatically adds the right filters, so only
the thread or CPU of the sample is displayed. Then we use less' search
functionality to directly jump to the time stamp of the selected sample.
It uses different menus for assembler and source display. Assembler
needs xed installed and source needs debuginfo.
- Fix the UI browser scripts pop up menu when there are many scripts
available.
perf report:
Andi Kleen:
- Add 'time' sort option. E.g.:
% perf report --sort time,overhead,symbol --time-quantum 1ms --stdio

tools headers:
Arnaldo Carvalho de Melo:
- Update x86's syscall_64.tbl, no change in tools/perf behaviour.
- Sync copies asm-generic/unistd.h and linux/in with the kernel sources.
perf data:
Jiri Olsa:
- Prep work to support having perf.data stored as a directory, with one
file per CPU, that ultimately will allow having one ring buffer reading
thread per CPU.
Vendor events:
Martin Liška:
- perf PMU events for AMD Family 17h.
perf script python:
Tony Jones:
- Add python3 support for the remaining Intel PT related scripts, with
these we should have a clean build of perf with python3 while still
supporting the build with python2.
libbpf:
Arnaldo Carvalho de Melo:
- Fix the build on uCLibc, adding the missing stdarg.h since we use
va_list in one typedef.

it needs fixing.

perf/x86/intel: Fix memory corruption
Through:
validate_event()
x86_pmu.get_event_constraints(.idx=-1)
tfa_get_event_constraints()
dyn_constraint()
cpuc->constraint_list[-1] is used, which is an obvious out-of-bound access.
In this case, simply skip the TFA constraint code, there is no event
constraint with just PMC3, therefore the code will never result in the
empty set.

We have a fairly balanced mix of clk driver updates and clk framework
updates this time around. It's the usual pile of new drivers for new
hardware out there and the normal small fixes and updates, but then we
have some core framework changes too.
In the core framework, we introduce support for a clk_get_optional() API
to get clks that may not always be populated and a way to devm manage clkdev
lookups registered by provider drivers. We also do some refactoring to simplify
the interface between clkdev and the common clk framework so we can reuse the DT
parsing and clk_get() path in provider drivers in the future. This work will
continue in the next few cycles while we convert how providers specify clk
parents.
On the driver side, the biggest part of the dirstat is the Amlogic clk driver
that got support for the G12A SoC. It dominates with almost half the overall
diff, while the second largest part of the diff is in the i.MX clk driver
that gained support for imx8mm SoCs. After that, we have the Actions Semiconductor
and Qualcomm drivers rounding out the big part of the dirstat because they both
got new hardware support for SoCs. The rest is just various updates and non-critical
fixes for existing drivers.
Core:
- Convert a few clk bindings to JSON schema format
- Add a {devm_}clk_get_optional() API
- Add devm_clk_hw_register_clkdev() API to manage clkdev lookups
- Start rewriting clk parent registration and supporting device links
by moving around code that supports clk_get() and DT parsing of the
'clocks' property
New Drivers:
- Add Qualcomm MSM8998 RPM managed clks
- IPA clk support on Qualcomm RPMh clk controllers
- Actions Semi S500 SoC clk support
- Support for fixed rate clks populated from an MMIO register
- Add RPC (QSPI/HyperFLASH) clocks on Renesas R-Car V3H
- Add TMU (timer) clocks on Renesas RZ/G2E
- Add Amlogic G12A Always-On Clock Controller
- Add 32k clock generation for Amlogic AXG
- Add support for the Mali GPU clocks on Amlogic Meson8
- Add Amlogic G12A EE clock controller driver
- Add missing CANFD clocks on Renesas RZ/G2M and RZ/G2E
- Add i.MX8MM SoC clk driver support
Removed Drivers:
- Remove clps711x driver as the board support is gone
Updates:
- 3rd ECO fix for Mediatek MT2712 SoCs
- Updates for Qualcomm MSM8998 GCC clks
- Random static analysis fixes for clk drivers
- Support for sleeping gpios in the clk-gpio type
- Minor fixes for STM32MP1 clk driver (parents, critical flag, etc.)
- Split LCDC into two clks on the Marvell MMP2 SoC
- Various DT of_node refcount fixes
- Get rid of CLK_IS_BASIC from TI code (yay!)
- TI Autoidle clk support
- Fix Amlogic Meson8 APB clock ID name
- Claim input clocks through DT for Amlogic AXG and GXBB
- Correct the DU (display unit) parent clock on Renesas RZ/G2E
- Exynos5433 IMEM CMU crypto clk support (SlimSS)
- Fix for the PLL-MIPI on the Allwinner A23
- Fix Rockchip rk3328 PLL rate calculation
- Add SET_RATE_PARENT flag on display clk of Rockhip rk3066
- i.MX SCU clk driver clk_set_parent() and cpufreq support

pptp: dst_release sk_dst_cache in pptp_sock_destruct
sk_setup_caps() is called to set sk->sk_dst_cache in pptp_connect,
so we have to dst_release(sk->sk_dst_cache) in pptp_sock_destruct,
otherwise, the dst refcnt will leak.
It can be reproduced by this syz log:
r1 = socket$pptp(0x18, 0x1, 0x2)
bind$pptp(r1, &(0x7f0000000100)={0x18, 0x2, {0x0, @local}}, 0x1e)
connect$pptp(r1, &(0x7f0000000000)={0x18, 0x2, {0x3, @remote}}, 0x1e)
Consecutive dmesg warnings will occur:
unregister_netdevice: waiting for lo to become free. Usage count = 1
v1->v2:
- use rcu_dereference_protected() instead of rcu_dereference_check(),
as suggested by Eric.

net/tls: Inform user space about send buffer availability
A previous fix ("tls: Fix write space handling") assumed that
user space application gets informed about the socket send buffer
availability when tls_push_sg() gets called. Inside tls_push_sg(), in
case do_tcp_sendpages() returns 0, the function returns without calling
ctx->sk_write_space. Further, the new function tls_sw_write_space()
did not invoke ctx->sk_write_space. This leads to situation that user
space application encounters a lockup always waiting for socket send
buffer to become available.
Rather than call ctx->sk_write_space from tls_push_sg(), it should be
called from tls_write_space. So whenever tcp stack invokes
sk->sk_write_space after freeing socket send buffer, we always declare
the same to user space by the way of invoking ctx->sk_write_space.

net_sched: return correct value for *notify* functions
It is confusing to directly use return value of netlink_send()/ netlink_unicast() as the return value of *notify*, as it may be not error at all. Example: in tc_del_tfilter(), after calling tfilter_del_notify(), it will goto errout if (err). However, the netlink_send()/netlink_unicast() will return positive value even for successful case. So it may not call tcf_chain_tp_remove() and so on to clean up the resource, as a result, resource is leaked. It may be easier to only check the return value of tfilter_del_nofiy(), but it is more clean to correct all related functions.

lan743x: Fix TX Stall Issue
It has been observed that tx queue may stall while downloading
from certain web sites (example www.speedtest.net)
The cause has been tracked down to a corner case where
the tx interrupt vector was disabled automatically, but
was not re enabled later.
The lan743x has two mechanisms to enable/disable individual
interrupts. Interrupts can be enabled/disabled by individual
source, and they can also be enabled/disabled by individual
vector which has been mapped to the source. Both must be
enabled for interrupts to work properly.
The TX code path, primarily uses the interrupt enable/disable of
the TX source bit, while leaving the vector enabled all the time.
However, while investigating this issue it was noticed that
the driver requested the use of the vector auto clear feature.
The test above revealed a case where the vector enable was
cleared unintentionally.
This patch fixes the issue by deleting the lines that request
the vector auto clear feature to be used.

Merge tag 'libnvdimm-for-5.1' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm
Pull libnvdimm updates from Dan Williams:
"The bulk of this has been in -next since before the merge window
opened, with no known collisions / issues reported.
The only detail worth noting, outside the summary below, is that the
"libnvdimm-start-pad" topic has been truncated to just cleanups and
small fixes. The full topic branch would have doubled down on hacks
around the "section alignment" limitation of the core-mm, instead
effort is now being spent to address that root issue in the memory
hotplug implementation for v5.2.
- Fix nfit-bus command submission regression
- Support retrieval of short-ARS results if the ARS state is
"requires continuation", and even if the "no_init_ars" module
parameter is specified
- Allow busy-polling of the kernel ARS state by allowing root to

mlx4_core misc fixes
This patchset by Jack contains misc fixes to the mlx4 Core driver.
Patch 1 fixes a use-after-free situation by marking (nullifying) the pointer,
please queue for -stable >= v4.0.
Patch 2 adds a missing lock acquire and release in SRIOV command interface,
please queue for -stable >= v4.9.
Patch 3 avoids calling roundup_pow_of_two when argument is zero,

net/mlx4_core: Fix qp mtt size calculation
Calculation of qp mtt size (in function mlx4_RST2INIT_wrapper)
ultimately depends on function roundup_pow_of_two.
If the amount of memory required by the QP is less than one page,
roundup_pow_of_two is called with argument zero. In this case, the
roundup_pow_of_two result is undefined.
Calling roundup_pow_of_two with a zero argument resulted in the
following stack trace:
UBSAN: Undefined behaviour in ./include/linux/log2.h:61:13

Fix this by explicitly testing for zero, and returning one if the

should be one).

net/mlx4_core: Fix locking in SRIOV mode when switching between events and polling
In procedures mlx4_cmd_use_events() and mlx4_cmd_use_polling(), we need to
guarantee that there are no FW commands in progress on the comm channel
(for VFs) or wrapped FW commands (on the PF) when SRIOV is active.
We do this by also taking the slave_cmd_mutex when SRIOV is active.
This is especially important when switching from event to polling, since we
free the command-context array during the switch. If there are FW commands
in progress (e.g., waiting for a completion event), the completion event
handler will access freed memory.
Since the decision to use comm_wait or comm_poll is taken before grabbing
the event_sem/poll_sem in mlx4_comm_cmd_wait/poll, we must take the
slave_cmd_mutex as well (to guarantee that the decision to use events or
polling and the call to the appropriate cmd function are atomic).

net/mlx4_core: Fix reset flow when in command polling mode
As part of unloading a device, the driver switches from
FW command event mode to FW command polling mode.
Part of switching over to polling mode is freeing the command context array
memory (unfortunately, currently, without NULLing the command context array
pointer).
The reset flow calls "complete" to complete all outstanding fw commands
(if we are in event mode). The check for event vs. polling mode here
is to test if the command context array pointer is NULL.
If the reset flow is activated after the switch to polling mode, it will
attempt (incorrectly) to complete all the commands in the context array --
because the pointer was not NULLed when the driver switched over to polling
mode.
As a result, we have a use-after-free situation, which results in a
kernel crash.
For example:

The highlights are:
- rbd will now ignore discards that aren't aligned and big enough to
actually free up some space (myself). This is controlled by the new
alloc_size map option and can be disabled if needed.
- support for rbd deep-flatten feature (myself). Deep-flatten allows
"rbd flatten" to fully disconnect the clone image and its snapshots
from the parent and make the parent snapshot removable.
- a new round of cap handling improvements (Zheng Yan). The kernel
client should now be much more prompt about releasing its caps and
it is possible to put a limit on the number of caps held.
- support for getting ceph.dir.pin extended attribute (Zheng Yan)

mlxsw: core: Prevent duplication during QSFP module initialization
Verify during thermal initialization if QSFP module's entry is already
configured in order to prevent duplication.
Such scenario could happen in case two switch drivers (PCI and I2C
based) coexist and if after boot, splitting configuration is applied
for some ports and then I2C based driver is re-probed.
In such case after reboot same QSFP module, associated with split will
be discovered by I2C based driver few times, and it will cause a crash.
It could happen for example on system equipped with BMC (Baseboard
Management Controller), running I2C based driver, when the next steps
are performed:
- System boot
- Host side configures port spilt.
- BMC side is rebooted.
