kbuild: fix 'No such file or directory' warning when cleaning
|
|
Kbuild descends into a directory by either 'y' or 'm', but there is an
important difference.
Kbuild combines the built-in objects into built-in.a in each directory.
The built-in.a in the directory visited by obj-y is merged into the
built-in.a in the parent directory. This merge happens recursively
when Kbuild is ascending back towards the top directory, then built-in
objects are linked into vmlinux eventually. This works properly only
when the Makefile specifying obj-y is reachable by the chain of obj-y.
On the other hand, Kbuild does not take built-in.a from the directory
visited by obj-m. This it, all the objects in that directory are
supposed to be modular. If Kbuild descends into a directory by obj-m,
but the Makefile in the sub-directory specifies obj-y, those objects
are just left orphan.
The current statement "Kbuild only uses this information to decide that
it needs to visit the directory" is misleading. Clarify the difference.

Pull powerpc fixes from Michael Ellerman:
"Two weeks worth of accumulated fixes:
- A fix for a performance regression seen on PowerVM LPARs using
dedicated CPUs, caused by our vcpu_is_preempted() returning true
even for idle CPUs.
- One of the ultravisor support patches broke KVM on big endian hosts
in v5.4.
- Our KUAP (Kernel User Access Prevention) code missed allowing
access in __clear_user(), which could lead to an oops or erroneous
SEGV when triggered via PTRACE_GETREGSET.
- Two fixes for the ocxl driver, an open/remove race, and a memory
leak in an error path.
- A handful of other small fixes.

Pull io_uring fixes from Jens Axboe:
"Here's a set of fixes that should go into 5.5-rc3 for io_uring.
This is bigger than I'd like it to be, mainly because we're fixing the
case where an application reuses sqe data right after issue. This
really must work, or it's confusing. With 5.5 we're flagging us as
submit stable for the actual data, this must also be the case for
SQEs.
Honestly, I'd really like to add another series on top of this, since
it cleans it up considerable and prevents any SQE reuse by design. I
posted that here:
https://lore.kernel.org/io-uring/20191220174742.7449-1-axboe@kernel.dk/T/#u
and may still send it your way early next week once it's been looked
at and had some more soak time (does pass all regression tests). With
that series, we've unified the prep+issue handling, and only the prep
phase even has access to the SQE.
Anyway, outside of that, fixes in here for a few other issues that
have been hit in testing or production"

for HPWMI_FEATURE2_QUERY requires an outsize of at least 128 bytes,
otherwise it fails with an error code 5 (HPWMI_RET_INVALID_PARAMETERS):
Dec 06 00:59:38 kernel: hp_wmi: query 0xd returned error 0x5
We do not care about the contents of the buffer, we just want to know
if the HPWMI_FEATURE2_QUERY command is supported.
This commits bumps the buffer size, fixing the error.

This is a follow-up commit for the sysfs attributes to change
from DRIVER_ATTR to DEVICE_ATTR according to some initial comments.
In such case, it's better to point the sysfs path to the device
itself instead of the driver. The ABI document is also updated.

gnttab_request_version() always sets the gnttab_interface variable

By simply re-attaching to shared rings during connect_ring() rather than
assuming they are freshly allocated (i.e assuming the counters are zero)
it is possible for vbd instances to be unbound and re-bound from and to
(respectively) a running guest.
This has been tested by running:
while true;
do fio --name=randwrite --ioengine=libaio --iodepth=16 \
--rw=randwrite --bs=4k --direct=1 --size=1G --verify=crc32;
done
in a PV guest whilst running:
while true;
do echo vbd-$DOMID-$VBD >unbind;
echo unbound;
sleep 5;
echo vbd-$DOMID-$VBD >bind;
echo bound;
sleep 3;
done
in dom0 from /sys/bus/xen-backend/drivers/vbd to continuously unbind and
re-bind its system disk image.
This is a highly useful feature for a backend module as it allows it to be
unloaded and re-loaded (i.e. updated) without requiring domUs to be halted.
This was also tested by running:
while true;
do echo vbd-$DOMID-$VBD >unbind;
echo unbound;
sleep 5;
rmmod xen-blkback;
echo unloaded;
sleep 1;
modprobe xen-blkback;
echo bound;
cd $(pwd);
sleep 3;
done
in dom0 whilst running the same loop as above in the (single) PV guest.
Some (less stressful) testing has also been done using a Windows HVM guest
with the latest 9.0 PV drivers installed.

Currently these macros are defined to re-initialize a front/back ring
(respectively) to values read from the shared ring in such a way that any
requests/responses that are added to the shared ring whilst the front/back
is detached will be skipped over. This, in general, is not a desirable
semantic since most frontend implementations will eventually block waiting
for a response which would either never appear or never be processed.
Since the macros are currently unused, take this opportunity to re-define
them to re-initialize a front/back ring using specified values. This also
allows FRONT/BACK_RING_INIT() to be re-defined in terms of
FRONT/BACK_RING_ATTACH() using a specified value of 0.
NOTE: BACK_RING_ATTACH() will be used directly in a subsequent patch.

If a driver probe() fails then leave the xenstore state alone. There is no
reason to modify it as the failure may be due to transient resource
allocation issues and hence a subsequent probe() may succeed.
If the driver supports re-binding then only force state to closed during
remove() only in the case when the toolstack may need to clean up. This can
be detected by checking whether the state in xenstore has been set to
closing prior to device removal.
NOTE: Re-bind support is indicated by new boolean in struct xenbus_driver,
which defaults to false. Subsequent patches will add support to
some backend drivers.

...and make it static
xenbus_dev_shutdown() is seemingly intended to cause clean shutdown of PV
frontends when a guest is rebooted. Indeed the function waits for a
conpletion which is only set by a call to xenbus_frontend_closed().
This patch removes the shutdown() method from backends and moves
xenbus_dev_shutdown() from xenbus_probe.c into xenbus_probe_frontend.c,
renaming it appropriately and making it static.
NOTE: In the case where the backend is running in a driver domain, the
toolstack should have already terminated any frontends that may be
using it (since Xen does not support re-startable PV driver domains)
so xenbus_dev_shutdown() should never be called.

Clang warns:

nr_parts = PARTS_PER_DISK;
^
../drivers/block/xen-blkfront.c:1115:3: note: previous statement is here

This is because there is a space at the beginning of this line; remove
it so that the indentation is consistent according to the Linux kernel
coding style and clang no longer warns.
While we are here, the previous line has some trailing whitespace; clean
that up as well.

A typical backtrace acquired from ftraced function currently looks like
the following (e.g. for "path_openat"):
arch_stack_walk+0x15c/0x2d8
stack_trace_save+0x50/0x68
stack_trace_call+0x15a/0x3b8
ftrace_graph_caller+0x0/0x1c
0x3e0007e3c98 <- ftraced function caller (should be do_filp_open+0x7c/0xe8)
do_open_execat+0x70/0x1b8
__do_execve_file.isra.0+0x7d8/0x860
__s390x_sys_execve+0x56/0x68
system_call+0xdc/0x2d8
Note random "0x3e0007e3c98" stack value as ftraced function caller. This
value causes either imprecise unwinder result or unwinding failure.
That "0x3e0007e3c98" comes from r14 of ftraced function stack frame, which
it haven't had a chance to initialize since the very first instruction
calls ftrace code ("ftrace_caller"). (ftraced function might never
save r14 as well). Nevertheless according to s390 ABI any function
is called with stack frame allocated for it and r14 contains return
address. "ftrace_caller" itself is called with "brasl %r0,ftrace_caller".
So, to fix this issue simply always save traced function caller onto
ftraced function stack frame.
