* tag 'powerpc-6.10-4' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux:
selftests/powerpc: Fix build with USERCFLAGS set
powerpc/pseries: Fix scv instruction crash with kexec
powerpc/eeh: avoid possible crash when edev->pdev changes
powerpc/pseries: Whitelist dtl slub object for copying to userspace
powerpc/64s: Fix unnecessary copy to 0 when kernel is booted at address 0
Currently building the powerpc selftests with USERCFLAGS set to anything
causes the build to break:
$ make -C tools/testing/selftests/powerpc V=1 USERCFLAGS=-Wno-error
...
gcc -Wno-error cache_shape.c ...
cache_shape.c:18:10: fatal error: utils.h: No such file or directory
18 | #include "utils.h"
| ^~~~~~~~~
compilation terminated.
This happens because the USERCFLAGS are added to CFLAGS in lib.mk, which
causes the check of CFLAGS in powerpc/flags.mk to skip setting CFLAGS at
all, resulting in none of the usual CFLAGS being passed. That can
be seen in the output above, the only flag passed to the compiler is
-Wno-error.
Fix it by dropping the conditional setting of CFLAGS in flags.mk.
Instead always set CFLAGS, but also append USERCFLAGS if they are set.
Note that appending to CFLAGS (with +=) wouldn't work, because flags.mk
is included by multiple Makefiles (to support partial builds), causing
CFLAGS to be appended to multiple times. Additionally that would place
the USERCFLAGS prior to the standard CFLAGS, meaning the USERCFLAGS
couldn't override the standard flags. Being able to override the
standard flags is desirable, for example for adding -Wno-error.
With the fix in place, the CFLAGS are set correctly, including the
USERCFLAGS:
$ make -C tools/testing/selftests/powerpc V=1 USERCFLAGS=-Wno-error
...
gcc -std=gnu99 -O2 -Wall -Werror -DGIT_VERSION='"v6.10-rc2-7-gdea17e7e56c3"'
-I/home/michael/linux/tools/testing/selftests/powerpc/include -Wno-error

In selftests/net/msg_zerocopy.c, it has a while loop keeps calling sendmsg
on a socket with MSG_ZEROCOPY flag, and it will recv the notifications
until the socket is not writable. Typically, it will start the receiving
process after around 30+ sendmsgs. However, as the introduction of commit
dfa2f04833 ("tcp: get rid of sysctl_tcp_adv_win_scale"), the sender is
always writable and does not get any chance to run recv notifications.
The selftest always exits with OUT_OF_MEMORY because the memory used by
opt_skb exceeds the net.core.optmem_max. Meanwhile, it could be set to a
different value to trigger OOM on older kernels too.
Thus, we introduce "cfg_notification_limit" to force sender to receive
notifications after some number of sendmsgs.

This kselftest fixes update for Linux 6.10-rc7 consists of one single
patch to fix the non-contiguous CBM resctrl:
- AMD supports non-contiguous CBM but does not report it via CPUID. This
test should not use CPUID on AMD to detect non-contiguous CBM support.
Fix the problem so the test uses CPUID to discover non-contiguous CBM
support only on Intel.

tools/power turbostat: Add local build_bug.h header for snapshot target
tools/power turbostat: Fix unc freq columns not showing with '-q' or '-l'
tools/power turbostat: option '-n' is ambiguous
We cannot use CLONE_VFORK because we also need to wait for the timeout
signal.
Restore tests timeout by using the original fork() call in __run_test()
but also in __TEST_F_IMPL(). Also fix a race condition when waiting for
the test child process.
Because test metadata are shared between test processes, only the
parent process must set the test PID (child). Otherwise, t->pid may be
set to zero, leading to inconsistent error cases:
# RUN layout1.rule_on_mountpoint ...
# rule_on_mountpoint: Test ended in some other way [127]
# OK layout1.rule_on_mountpoint
ok 20 layout1.rule_on_mountpoint
As safeguards, initialize the "status" variable with a valid exit code,
and handle unknown test exits as errors.
The use of fork() introduces a new race condition in landlock/fs_test.c
which seems to be specific to hostfs bind mounts, but I haven't found
the root cause and it's difficult to trigger. I'll try to fix it with
another patch.

Commit 78464d7681 ("tools/power turbostat: Add columns for clustered
uncore frequency") introduced 'probe_intel_uncore_frequency_cluster()'
in a way which prevents printing uncore frequency columns if either of
the '-q' or '-l' options are used. Systems which do not have multiple
uncore frequencies per package are unaffected by this regression.
Fix the function so that uncore frequency columns are shown when either
the '-l' or '-q' option is used by checking if 'quiet' is true after
adding counters for the uncore frequency columns.

In some cases specifying the '-n' command line argument will cause
turbostat to fail. For instance 'turbostat -n 1' works fine; however,
'turbostat -n 1 -d' will fail. This is the result of the first call
to getopt_long_only() where "MP" is specified as the optstring. This can
be easily fixed by changing the optstring from "MP" to "MPn:" to remove
ambiguity between the arguments.
tools/power turbostat: option '-n' is ambiguous; possibilities: '-num_iterations' '-no-msr' '-no-perf'

When SO_OOBINLINE is enabled on a socket, MSG_OOB can be recv()ed
without MSG_OOB flag, and ioctl(SIOCATMARK) will behaves differently.
This patch adds some test cases for SO_OOBINLINE.
Note the new test cases found two bugs in TCP.
1) After reading OOB data with non-inline mode, we can re-read
the data by setting SO_OOBINLINE.
# RUN msg_oob.no_peek.inline_oob_ahead_break ...
# msg_oob.c:146:inline_oob_ahead_break:AF_UNIX :world

# OK msg_oob.no_peek.inline_oob_ahead_break
ok 14 msg_oob.no_peek.inline_oob_ahead_break
2) The head OOB data is dropped if SO_OOBINLINE is disabled
if a new OOB data is queued.

Currently, recv() is stopped at a consumed OOB skb even if a new
OOB skb is queued and we can ignore the old OOB skb.
>>> from socket import *
>>> c1, c2 = socket(AF_UNIX, SOCK_STREAM)
>>> c1.send(b'hellowor', MSG_OOB)

>>> c2.recv(1, MSG_OOB) # consume OOB data stays at middle of recvq.
b'r'
>>> c1.send(b'ld', MSG_OOB)
2
>>> c2.recv(10) # recv() stops at the old consumed OOB
b'hellowo' # should be 'hellowol'
manage_oob() should not stop recv() at the old consumed OOB skb if
there is a new OOB data queued.
Note that TCP behaviour is apparently wrong in this test case because
we can recv() the same OOB data twice.

While testing, I found some weird behaviour on the TCP side as well.
For example, TCP drops the preceding OOB data when queueing a new
OOB data if the old OOB data is at the head of recvq.
# RUN msg_oob.no_peek.ex_oob_drop ...
# msg_oob.c:146:ex_oob_drop:AF_UNIX :x
# msg_oob.c:147:ex_oob_drop:TCP :Resource temporarily unavailable

# OK msg_oob.no_peek.ex_oob_drop_2

This patch allows AF_UNIX's MSG_OOB implementation to produce different
results from TCP when operations are guarded with tcp_incompliant{}.

Let's say a socket send()s "hello" with MSG_OOB and "world" without flags,
>>> from socket import *
>>> c1, c2 = socketpair(AF_UNIX)
>>> c1.send(b'hello', MSG_OOB)
5
>>> c1.send(b'world')
5
and its peer recv()s "hell" and "o".
>>> c2.recv(10)
b'hell'
>>> c2.recv(1, MSG_OOB)
b'o'
Now the consumed OOB skb stays at the head of recvq to return a correct
value for ioctl(SIOCATMARK), which is broken now and fixed by a later
patch.
Then, if peer issues recv() with MSG_DONTWAIT, manage_oob() returns NULL,
so recv() ends up with -EAGAIN.
>>> c2.setblocking(False) # This causes -EAGAIN even with available data
>>> c2.recv(5)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
BlockingIOError: [Errno 11] Resource temporarily unavailable
However, next recv() will return the following available data, "world".
>>> c2.recv(5)
b'world'
When the consumed OOB skb is at the head of the queue, we need to fetch
the next skb to fix the weird behaviour.
Note that the issue does not happen without MSG_DONTWAIT because we can
retry after manage_oob().
This patch also adds a test case that covers the issue.
Without fix:
# RUN msg_oob.no_peek.ex_oob_break ...

After consuming OOB data, recv() reading the preceding data must break at
the OOB skb regardless of MSG_PEEK.
Currently, MSG_PEEK does not stop recv() for AF_UNIX, and the behaviour is
not compliant with TCP.
>>> from socket import *
>>> c1, c2 = socketpair(AF_UNIX)
>>> c1.send(b'hello', MSG_OOB)
5
>>> c1.send(b'world')
5
>>> c2.recv(1, MSG_OOB)
b'o'
>>> c2.recv(9, MSG_PEEK) # This should return b'hell'
b'hellworld' # even with enough buffer.
Let's fix it by returning NULL for consumed skb and unlinking it only if
MSG_PEEK is not specified.
This patch also adds test cases that add recv(MSG_PEEK) before each recv().

some bizarre behaviour.
The new selftest validates every MSG_OOB operation against TCP as a

test_unix_oob.c does not fully cover AF_UNIX's MSG_OOB functionality,
thus there are discrepancies between TCP behaviour.
Also, the test uses fork() to create message producer, and it's not

Since interleave capability is not verified, if the interleave
capability of a target does not match the region need, committing decoder
should have failed at the device end.
In order to checkout this error as quickly as possible, driver needs
to check the interleave capability of target during attaching it to
region.
Per CXL specification r3.1(8.2.4.20.1 CXL HDM Decoder Capability Register),
bits 11 and 12 indicate the capability to establish interleaving in 3, 6,
12 and 16 ways. If these bits are not set, the target cannot be attached to
a region utilizing such interleave ways.
Additionally, bits 8 and 9 represent the capability of the bits used for
interleaving in the address, Linux tracks this in the cxl_port
interleave_mask.
Per CXL specification r3.1(8.2.4.20.13 Decoder Protection):
eIW means encoded Interleave Ways.
eIG means encoded Interleave Granularity.
in HPA:
if eIW is 0 or 8 (interleave ways: 1, 3), all the bits of HPA are used,
the interleave bits are none, the following check is ignored.
if eIW is less than 8 (interleave ways: 2, 4, 8, 16), the interleave bits
start at bit position eIG + 8 and end at eIG + eIW + 8 - 1.
if eIW is greater than 8 (interleave ways: 6, 12), the interleave bits
start at bit position eIG + 8 and end at eIG + eIW - 1.
if the interleave mask is insufficient to cover the required interleave
bits, the target cannot be attached to the region.

openvswitch.sh makes use of substitutions of the form ${ns:0:1}, to
obtain the first character of $ns. Empirically, this is works with bash
but not dash. When run with dash these evaluate to an empty string and
printing an error to stdout.
# dash -c 'ns=client; echo "${ns:0:1}"' 2>error
# cat error
dash: 1: Bad substitution
# bash -c 'ns=client; echo "${ns:0:1}"' 2>error
c
# cat error
This leads to tests that neither pass nor fail.
F.e.
TEST: arp_ping [START]
adding sandbox 'test_arp_ping'
Adding DP/Bridge IF: sbx:test_arp_ping dp:arpping {, , }
create namespaces
./openvswitch.sh: 282: eval: Bad substitution
TEST: ct_connect_v4 [START]
adding sandbox 'test_ct_connect_v4'
Adding DP/Bridge IF: sbx:test_ct_connect_v4 dp:ct4 {, , }
./openvswitch.sh: 322: eval: Bad substitution
create namespaces
Resolve this by making openvswitch.sh a bash script.

It is important to have fixed (sub)test names in TAP, because these
names are used to identify them. If they are not fixed, tracking cannot
be done.
Some subtests from the userspace_pm selftest were using random numbers
in their names: the client and server address IDs from $RANDOM, and the
client port number randomly picked by the kernel when creating the
connection. These values have been replaced by 'client' and 'server'
words: that's even more helpful than showing random numbers. Note that
the addresses IDs are incremented and decremented in the test: +1 or -1
are then displayed in these cases.
Not to loose info that can be useful for debugging in case of issues,
these random numbers are now displayed at the beginning of the test.
