libbpf: Fix up generation of bpf_helper_defs.h
$ make -C tools/perf build-test
does, ends up with these two problems:
make[3]: *** No rule to make target '/tmp/tmp.zq13cHILGB/perf-5.3.0/include/uapi/linux/bpf.h', needed by 'bpf_helper_defs.h'. Stop.
make[3]: *** Waiting for unfinished jobs....
make[2]: *** [Makefile.perf:757: /tmp/tmp.zq13cHILGB/perf-5.3.0/tools/lib/bpf/libbpf.a] Error 2
make[2]: *** Waiting for unfinished jobs....
Because $(srcdir) points to the /tmp/tmp.zq13cHILGB/perf-5.3.0 directory
and we need '/tools/ after that variable, and after fixing this then we
get to another problem:
/bin/sh: /home/acme/git/perf/tools/scripts/bpf_helpers_doc.py: No such file or directory
make[3]: *** [Makefile:184: bpf_helper_defs.h] Error 127
make[3]: *** Deleting file 'bpf_helper_defs.h'
LD /tmp/build/perf/libapi-in.o
make[2]: *** [Makefile.perf:778: /tmp/build/perf/libbpf.a] Error 2
make[2]: *** Waiting for unfinished jobs....
Because this requires something outside the tools/ directories that gets
collected into perf's detached tarballs, to fix it just add it to
tools/perf/MANIFEST, which this patch does, now it works for that case
and also for all these other cases.

libceph, rbd, ceph: convert to use the new mount API
Convert the ceph filesystem to the new internal mount API as the old one will be obsoleted and removed. This allows greater flexibility in communication of mount parameters between userspace, the VFS and the filesystem. See Documentation/filesystems/mount_api.txt for more information. [ Numerous string handling, leak and regression fixes; rbd conversion was particularly broken and had to be redone almost from scratch. ] Signed-off-by: David Howells <dhowells@redhat.com> Signed-off-by: Jeff Layton <jlayton@kernel.org> Signed-off-by: Ilya Dryomov <idryomov@gmail.com> |

New tracing features:
- PERAMAENT flag to ftrace_ops when attaching a callback to a function
As /proc/sys/kernel/ftrace_enabled when set to zero will disable all
attached callbacks in ftrace, this has a detrimental impact on live
kernel tracing, as it disables all that it patched. If a ftrace_ops
is registered to ftrace with the PERMANENT flag set, it will prevent
ftrace_enabled from being disabled, and if ftrace_enabled is already
disabled, it will prevent a ftrace_ops with PREMANENT flag set from
being registered.
- New register_ftrace_direct(). As eBPF would like to register its own
trampolines to be called by the ftrace nop locations directly,
without going through the ftrace trampoline, this function has been
added. This allows for eBPF trampolines to live along side of
ftrace, perf, kprobe and live patching. It also utilizes the ftrace
enabled_functions file that keeps track of functions that have been
modified in the kernel, to allow for security auditing.
- Allow for kernel internal use of ftrace instances. Subsystems in
the kernel can now create and destroy their own tracing instances
which allows them to have their own tracing buffer, and be able
to record events without worrying about other users from writing over
their data.
- New seq_buf_hex_dump() that lets users use the hex_dump() in their
seq_buf usage.
- Notifications now added to tracing_max_latency to allow user space
to know when a new max latency is hit by one of the latency tracers.
- Wider spread use of generic compare operations for use of bsearch and
friends.
- More synthetic event fields may be defined (32 up from 16)
- Use of xarray for architectures with sparse system calls, for the
system call trace events.
This along with small clean ups and fixes.

powerpc fixes for Spectre-RSB
We failed to activate the mitigation for Spectre-RSB (Return Stack Buffer, aka. ret2spec) on context switch, on CPUs prior to Power9 DD2.3. That allows a process to poison the RSB (called Link Stack on Power CPUs) and possibly misdirect speculative execution of another process. If the victim process can be induced to execute a leak gadget then it may be possible to extract information from the victim via a side channel. The fix is to correctly activate the link stack flush mitigation on all CPUs that have any mitigation of Spectre v2 in userspace enabled. There's a second commit which adds a link stack flush in the KVM guest exit path. A leak via that path has not been demonstrated, but we believe it's at least theoretically possible. This is the fix for CVE-2019-18660. -----BEGIN PGP SIGNATURE----- iQJHBAABCAAxFiEEJFGtCPCthwEv2Y/bUevqPMjhpYAFAl3eUXsTHG1wZUBlbGxl cm1hbi5pZC5hdQAKCRBR6+o8yOGlgEXtD/4qiCp4OHo+MEFbDyqZHZSYdFihpZ2B 9s8yQKMaL0WWVJU0rlKSY0fDW/W0pLUn1zoREY9kRIHrQQi9wd5kg6s2kZtDeIPZ XPANeOpicMJjKGA+s/CqJfJZmGhzQ6VYplg/qevjvgOZqn8QsQhljg85w3Tr2wjo oXyi/0ZNv957pYrTHu08YIRr5OxalcE6Cxb4hZBqwbcubwKANSifLb72hcDEkNdR wshmt6mZUMtW8ToaGGt2b0csF2I0TClvBLQV8bxlbMZNFPYgUfBaHyCtHnv6bX65 Jlgyw46pv9o0aeIF24rmP9jDEX+Hcig5Qu/EdLkd9lDl5YMxxVv9LlGq8tt7TQjI J97DeUFYjvePGMzirPFc7EvEoN35f19/5IuZUEQQ8wE4I/R1gNqOxbpGUqvReTbA +WJHqqT6sbJ1ys/mWRlGYMkn1xPNG3scpTNNh9/f3f/+ci3knOeYNeieVjjFvIv0 4+toMQGIU7gB0mU67oLyClygOvC0DeBSQk8nFk0pznzUqdQlsqnbbI5O0KWFjf57 jZV9l5khfdkkZiTIkGEZ3RY7X4pcrKd4kI+5+2OLiZOQVw2rudE3+ocysxP0osmA Ec+dr3uxL1YKdR4GVvk5mCMNlln6PpfT5Y21YSiipnGsWC1hvYkbPaj4u/T5oV5T B1bP/R7gQw4yfQ== =NQFt -----END PGP SIGNATURE----- Merge tag 'powerpc-spectre-rsb' of powerpc-CVE-2019-18660.bundle Pull powerpc Spectre-RSB fixes from Michael Ellerman: "We failed to activate the mitigation for Spectre-RSB (Return Stack Buffer, aka. ret2spec) on context switch, on CPUs prior to Power9 DD2.3.

bpf: Support pre-2.25-binutils objcopy for vmlinux BTF
If vmlinux BTF generation fails, but CONFIG_DEBUG_INFO_BTF is set,
.BTF section of vmlinux is empty and kernel will prohibit
BPF loading and return "in-kernel BTF is malformed".
--dump-section argument to binutils' objcopy was added in version 2.25.
When using pre-2.25 binutils, BTF generation silently fails. Convert
to --only-section which is present on pre-2.25 binutils.
Documentation/process/changes.rst states that binutils 2.21+
is supported, not sure those standards apply to BPF subsystem.
v2:
* exit and print an error if gen_btf fails (John Fastabend)
v3:
* resend with Andrii's Acked-by/Tested-by tags

Driver core patches for 5.5-rc1
Here is the "big" set of driver core patches for 5.5-rc1 There's a few minor cleanups and fixes in here, but the majority of the patches in here fall into two buckets: - debugfs api cleanups and fixes - driver core device link support for boot dependancy issues The debugfs api cleanups are working to slowly refactor the debugfs apis so that it is even harder to use incorrectly. That work has been happening for the past few kernel releases and will continue over time, it's a long-term project/goal The driver core device link support missed 5.4 by just a bit, so it's been sitting and baking for many months now. It's from Saravana Kannan to help resolve the problems that DT-based systems have at boot time with dependancy graphs and kernel modules. Turns out that no one has actually tried to build a generic arm64 kernel with loads of modules and have it "just work" for a variety of platforms (like a distro kernel) The big problem turned out to be a lack of depandancy information between different areas of DT entries, and the work here resolves that problem and now allows devices to boot properly, and quicker than a monolith kernel.

This is the bulk of pin control changes for the v5.5 kernel
series:
Core changes:
- Avoid taking direct references to device tree-supplied
device names: these may changed at runtime under certain
circumstances to kstrdup them.
GPIO related:
- Work is ongoing to move to passing the irqchip along as a
templated struct gpio_irq_chip when adding a standard
gpiolib-based irqchip to a GPIO controller, a few patches
in this cycle switches a few pin control drivers over to
using this method.
New hardware support:
- Intel Lightning Mountain SoC pin controller and GPIO
support, a first Intel platform to use device tree rather
than ACPI to configure the system. News reports says that
this SoC is a network processor.
- Qualcomm MSM8976 and MSM8956
- Qualcomm PMIC GPIO now also supports PM6150 and PM6150L
- Qualcomm SPMI MPP and SPMI GPIO for PM8950 and PMI8950
- Rockchip RK3308
- Renesas R8A77961
- Allwinner Meson-A1
Driver improvements:
- get_multiple and set_multiple support for the AT91-PIO4 driver.
- Convert Qualcomm SSBI GPIO to use the hierarchical IRQ helpers
in the GPIOlib irqchip.

It is pretty much business as usual, the most interesting thing I
think is the pin controller for a new Intel chip called Lightning

decided to use device tree to describe the system rather than ACPI
that they have traditionally favored.

drm/i915/gt: Defer breadcrumb processing to after the irq handler
The design of our interrupt handlers is that we ack the receipt of the interrupt first, inside the critical section where the master interrupt control is off and other cpus cannot start processing the next interrupt; and then process the interrupt events afterwards. However, Icelake introduced a whole new set of banked GT_IIR that are inherently serialised and slow to retrieve the IIR and must be processed within the critical section. We can still push our breadcrumbs out of this critical section by using our irq_worker. On bdw+, this should not make too much of a difference as we only slightly defer the breadcrumbs, but on icl+ this should make a big difference to our throughput of interrupts from concurrently executing engines.

ALSA: hda: hdmi - fix regression in connect list handling
Fix regression in how intel_haswell_fixup_connect_list()
results are used in hda_read_pin_conn(). Use of
snd_hda_get_raw_connections() in hda_read_pin_conn() bypasses
the cache and thus also bypasses the overridden pin connection
list. On platforms that require the connection list fixup,
mux list will be empty and HDMI playback will fail to -EBUSY
at open.
Fix the regression in hda_read_pinn_conn(). Simplify code
as suggested by Takashi Iwai to remove old
intel_haswell_fixup_connect_list() and copy the cvt_nid list
directly and not use snd_hda_override_conn_list() at all.
Fixes:

drm/scheduler: Avoid accessing freed bad job.
Problem: Due to a race between drm_sched_cleanup_jobs in sched thread and drm_sched_job_timedout in timeout work there is a possiblity that bad job was already freed while still being accessed from the timeout thread. Fix: Instead of just peeking at the bad job in the mirror list remove it from the list under lock and then put it back later when we are garanteed no race with main sched thread is possible which is after the thread is parked. v2: Lock around processing ring_mirror_list in drm_sched_cleanup_jobs. v3: Rebase on top of drm-misc-next. v2 is not needed anymore as drm_sched_get_cleanup_job already has a lock there. v4: Fix comments to relfect latest code in drm-misc.

ASoC: max98090: fix possible race conditions
max98090_interrupt() and max98090_pll_work() run in 2 different threads.
There are 2 possible races:
Note: M98090_REG_DEVICE_STATUS = 0x01.
Note: ULK == 0, PLL is locked; ULK == 1, PLL is unlocked.
max98090_interrupt max98090_pll_work
----------------------------------------------
schedule max98090_pll_work
restart max98090 codec
receive ULK INT
assert ULK == 0
schedule max98090_pll_work (1).
In the case (1), the PLL is locked but max98090_interrupt unnecessarily
schedules another max98090_pll_work.
max98090_interrupt max98090_pll_work max98090 codec
----------------------------------------------------------------------
ULK = 1
receive ULK INT
read 0x01
ULK = 0 (clear on read)
schedule max98090_pll_work
restart max98090 codec
ULK = 1
receive ULK INT
read 0x01
ULK = 0 (clear on read)
read 0x01
assert ULK == 0 (2).
In the case (2), both max98090_interrupt and max98090_pll_work read
the same clear-on-read register. max98090_pll_work would falsely
thought PLL is locked.
Note: the case (2) race is introduced by the previous commit ("ASoC:
max98090: exit workaround earlier if PLL is locked") to check the status
and exit the loop earlier in max98090_pll_work.
There are 2 possible solution options:
A. turn off ULK interrupt before scheduling max98090_pll_work; and turn
on again before exiting max98090_pll_work.
B. remove the second thread of execution.
Option A cannot fix the case (2) race because it still has 2 threads
access the same clear-on-read register simultaneously. Although we
could suppose the register is volatile and read the status via I2C could
be much slower than the hardware raises the bits.
Option B introduces a maximum 10~12 msec penalty delay in the interrupt
handler. However, it could only punish the jack detection by extra
10~12 msec.
Adopts option B which is the better solution overall.
