[PATCH] ovl: add splice file read write helper

by Leah Rumancik

From: Murphy Zhou <jencce.kernel(a)gmail.com> Now overlayfs falls back to use default file splice read and write, which is not compatiple with overlayfs, returning EFAULT. xfstests generic/591 can reproduce part of this.

[PATCH] mfd: qcom-pm8xxx: Switch to nested IRQ handler

by Linus Walleij

After facing problems when using the chained interrupt for handling the PM8xxx IRQs we solve the issue by simply requesting the IRQ from the producer (in this case the TLMM) as any other IRQ, and nesting any consumer IRQs. Recently the driver is hanging during probe: [ 1.646990] ssbi 500000.qcom,ssbi: SSBI controller type: 'pmic-arbiter' [ 1.650901] pm8xxx_probe: PMIC revision 1: E3 [ 1.655078] pm8xxx_probe: PMIC revision 2: 00 (...) it just hangs after this. I am unable to bisect down to what is causing this hang, but the patch fixes the problem. After this patch the DragonBoard APQ8060 boots to prompt without problems.

[tip: x86/urgent] x86/resctrl: Fix a maybe-uninitialized build warning treated as error

by tip-bot2 for Babu Moger

The following commit has been merged into the x86/urgent branch of tip: Commit-ID: 527f721478bce3f49b513a733bacd19d6f34b08c Gitweb: https://git.kernel.org/tip/527f721478bce3f49b513a733bacd19d6f34b08c Author: Babu Moger <babu.moger(a)amd.com> AuthorDate: Fri, 20 Aug 2021 16:52:42 -05:00 Committer: Borislav Petkov <bp(a)suse.de> CommitterDate: Sun, 22 Aug 2021 09:11:29 +02:00 x86/resctrl: Fix a maybe-uninitialized build warning treated as error The recent commit 064855a69003 ("x86/resctrl: Fix default monitoring groups reporting") caused a RHEL build failure with an uninitialized variable warning treated as an error because it removed the default case snippet. The RHEL Makefile uses '-Werror=maybe-uninitialized' to force possibly uninitialized variable warnings to be treated as errors. This is also reported by smatch via the 0day robot. The error from the RHEL build is: arch/x86/kernel/cpu/resctrl/monitor.c: In function ‘__mon_event_count’: arch/x86/kernel/cpu/resctrl/monitor.c:261:12: error: ‘m’ may be used uninitialized in this function [-Werror=maybe-uninitialized] m->chunks += chunks; ^~ The upstream Makefile does not build using '-Werror=maybe-uninitialized'. So, the problem is not seen there. Fix the problem by putting back the default case snippet. [ bp: note that there's nothing wrong with the code and other compilers do not trigger this warning - this is being done just so the RHEL compiler is happy. ] Fixes: 064855a69003 ("x86/resctrl: Fix default monitoring groups reporting") Reported-by: Terry Bowman <Terry.Bowman(a)amd.com> Reported-by: kernel test robot <lkp(a)intel.com> Signed-off-by: Babu Moger <babu.moger(a)amd.com> Signed-off-by: Borislav Petkov <bp(a)suse.de> Reviewed-by: Reinette Chatre <reinette.chatre(a)intel.com> Cc: stable(a)vger.kernel.org Link: https://lkml.kernel.org/r/162949631908.23903.17090272726012848523.stgit@bmo… --- arch/x86/kernel/cpu/resctrl/monitor.c | 6 ++++++ 1 file changed, 6 insertions(+) diff --git a/arch/x86/kernel/cpu/resctrl/monitor.c b/arch/x86/kernel/cpu/resctrl/monitor.c index 57e4bb6..8caf871 100644 --- a/arch/x86/kernel/cpu/resctrl/monitor.c +++ b/arch/x86/kernel/cpu/resctrl/monitor.c @@ -304,6 +304,12 @@ static u64 __mon_event_count(u32 rmid, struct rmid_read *rr) case QOS_L3_MBM_LOCAL_EVENT_ID: m = &rr->d->mbm_local[rmid]; break; + default: + /* + * Code would never reach here because an invalid + * event id would fail the __rmid_read. + */ + return RMID_VAL_ERROR; } if (rr->first) {

[PATCH v2] x86/efi: Restore Firmware IDT before calling ExitBootServices()

by Joerg Roedel

From: Joerg Roedel <jroedel(a)suse.de> Commit 79419e13e808 ("x86/boot/compressed/64: Setup IDT in startup_32 boot path") introduced an IDT into the 32 bit boot path of the decompressor stub. But the IDT is set up before ExitBootServices() is called and some UEFI firmwares rely on their own IDT. Save the firmware IDT on boot and restore it before calling into EFI functions to fix boot failures introduced by above commit.

From: "Steven Rostedt (VMware)" <rostedt(a)goodmis.org> The selftest for ftrace checks some features by checking if the README has text that states the feature is supported by that kernel.

Aborted tests ------------- Tests that didn't complete running successfully are marked with ⚡⚡⚡. If this was caused by an infrastructure issue, we try to mark that explicitly in the report. Waived tests ------------ If the test run included waived tests, they are marked with 🚧. Such tests are executed but their results are not taken into account. Tests are waived when their results are not reliable enough, e.g. when they're just introduced or are being fixed. Testing timeout --------------- We aim to provide a report within reasonable timeframe. Tests that haven't finished running yet are marked with ⏱.

[PATCH v9 3/6] selftests/ftrace: Fix requirement check of README file

by Steven Rostedt

From: "Steven Rostedt (VMware)" <rostedt(a)goodmis.org> The selftest for ftrace checks some features by checking if the README has text that states the feature is supported by that kernel. Unfortunately, this check gives false positives because it many not be checked if there's spaces in the string to check. This is due to the compare between the required variable with the ":README" string stripped, because neither has quotes around them. Cc: Shuah Khan <shuah(a)kernel.org> Cc: Shuah Khan <skhan(a)linuxfoundation.org> Cc: linux-kselftest(a)vger.kernel.org Cc: stable(a)vger.kernel.org Fixes: 1b8eec510ba64 ("selftests/ftrace: Support ":README" suffix for requires") Signed-off-by: Steven Rostedt (VMware) <rostedt(a)goodmis.org> --- tools/testing/selftests/ftrace/test.d/functions | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/tools/testing/selftests/ftrace/test.d/functions b/tools/testing/selftests/ftrace/test.d/functions index f68d336b961b..000fd05e84b1 100644 --- a/tools/testing/selftests/ftrace/test.d/functions +++ b/tools/testing/selftests/ftrace/test.d/functions @@ -137,7 +137,7 @@ check_requires() { # Check required files and tracers echo "Required tracer $t is not configured." exit_unsupported fi - elif [ $r != $i ]; then + elif [ "$r" != "$i" ]; then if ! grep -Fq "$r" README ; then echo "Required feature pattern \"$r\" is not in README." exit_unsupported -- 2.30.2

Please apply commit cca342d98bef ("Bluetooth: hidp: use correct wait queue when removing ctrl_wait") to 5.10.y

by Salvatore Bonaccorso

Hi Tim Connors, a user in Debian (https://bugs.debian.org/992121) reported that cca342d98bef ("Bluetooth: hidp: use correct wait queue when removing ctrl_wait") from 5.11-rc1 is missing for the 5.10.y stable series. Actually would apply further back, but it was only tested to fix the problem on 5.10.y Thanks for considering, Regards, Salvatore
