[Linux-stable-mirror] [PATCH] MIPS: Schedule on CPUs we need to lose FPU for a mode switch

by Paul Burton

Commit 6b8322576e9d ("MIPS: Force CPUs to lose FP context during mode switches") ensures that we react to PR_SET_FP_MODE prctl syscalls quickly by broadcasting an IPI in order to cause CPUs to lose FPU access when necessary. Whilst it achieves that, unfortunately it causes all sorts of strange race conditions because: 1) The IPI may arrive at a point where the FPU is in the process of being enabled, but that process is not yet complete leading to a state we aren't prepared to handle. For example: do_cpu invoked from kernel context![#1]: CPU: 0 PID: 963 Comm: fp-prctl Not tainted 4.9.0-rc5-00323-g210db32-dirty #226 task: a8000000fd672e00 task.stack: a8000000fd630000 $ 0 : 0000000000000000 0000000000000001 0000000000000001 a8000000fd630000 $ 4 : a8000000fd672e00 0000000000000000 0000000000000453 0000000000000000 $ 8 : 0000000000000000 a8000000fd637c28 1000000000000000 0000000000000010 $12 : 00000000140084e0 ffffffff80109c00 0000000000000000 0000000000000002 $16 : ffffffff8092f080 a8000000fd672e00 ffffffff80107fe8 a8000000fd485000 $20 : ffffffff8084d328 ffffffff80940000 0000000000000009 ffffffff80930000 $24 : 0000000000000000 900000001612048c $28 : a8000000fd630000 a8000000fd637ac0 ffffffff80937300 ffffffff8010807c Hi : 0000000000000000 Lo : 0000000000000200 epc : ffffffff80115d38 _save_fp+0x10/0xa0 ra : ffffffff8010807c prepare_for_fp_mode_switch+0x94/0x1b0 Status: 140084e2 KX SX UX KERNEL EXL Cause : 1080002c (ExcCode 0b) PrId : 0001a428 (MIPS P6600) Modules linked in: Process fp-prctl (pid: 963, threadinfo=a8000000fd630000, task=a8000000fd672e00, tls=00000000756e67d0) Stack : 0000000000000000 a8000000fd557dc0 0000000000000000 ffffffff801ca8e0 0000000000000000 a8000000fd637b9c 0000000000000009 ffffffff80923780 ffffffff80850000 ffffffff8011610c 00000000000000b8 ffffffff801a5084 ffffffff8084a370 ffffffff8084a388 ffffffff80923780 ffffffff80923828 0000000000010000 ffffffff809237a8 0000000000020000 ffffffff80a40000 000000000000007c 00000000004a0000 00000000756dedd0 ffffffff801a5188 a800000002014900 0000000000000001 ffffffff80923780 0000000080923828 ffffffff80923780 ffffffff80923780 ffffffff80923828 ffffffff801a521c ffffffff80923780 ffffffff80923828 0000000000010000 ffffffff801a8f84 ffffffff80a40000 a8000000fd637c20 ffffffff80a39240 0000000000000001 ...

If this happens then the IPI will be serviced & we'll proceed to enable an FPU whilst the mode switch is in progress, leading to strange & inconsistent behaviour. Further to all of this is a separate but related problem: 4) There are various paths through which we may enable the FPU without the user having triggered a coprocessor 1 disabled exception. These paths are those in which we emulate instructions & then enable the FPU with the expectation that the user might execute an FP instruction shortly afterwards. However these paths have not previously checked whether an FP mode switch is underway for the task, and therefore could enable the FPU whilst such a mode switch is in progress leading to strange & inconsistent behaviour for user code. This patch fixes all of the above by taking a step back & re-examining our approach to FP mode switches. Up until now we have taken these basic steps: a) Prevent any threads that are part of the affected process from being able to obtain ownership of the FPU. b) Cause any threads that are part of the affected process and already have ownership of an FPU to lose it. c) Set the thread flags for each thread that is part of the affected process to reflect the new FP mode. d) Allow threads to obtain ownership of the FPU again. This approach is however more complex than necessary. All that we really require is that the mode switch has occurred for all threads that are part of the affected process before mips_set_process_fp_mode(), and thus the PR_SET_FP_MODE prctl() syscall, returns. This doesn't require that we stop threads from owning or using an FPU whilst a mode switch occurs, only that we force them to relinquish it after the mode switch has occurred such that they next own an FPU with the correct mode configured. Our basic steps therefore simplify to: A) Set the thread flags for each thread that is part of the affected process to reflect the new FP mode. B) Cause any threads that are part of the affected process and already have ownership of an FPU to lose it. We implement B) by forcing each CPU which might be running a thread which is part of the affected process to schedule a no-op function, which causes the affected thread to lose its FPU ownership when it is descheduled. The end result is simpler FP mode switching with less overhead in the FPU enable path (ie. enable_restore_fp_context()) and fewer moving parts.

[Linux-stable-mirror] [PATCH v2] gpio: fix "gpio-line-names" property retrieval

by Christophe Leroy

Following commit 9427ecbed46cc ("gpio: Rework of_gpiochip_set_names() to use device property accessors"), "gpio-line-names" DT property is not retrieved anymore when chip->parent is not set by the driver. This is due to OF based property reads having been replaced by device based property reads. This patch fixes that by making use of fwnode_property_read_string_array() instead of device_property_read_string_array() and handing over either of_fwnode_handle(chip->of_node) or dev_fwnode(chip->parent) to that function.

[Linux-stable-mirror] [PATCH] USB: Fix off by one in type-specific length check of BOS SSP capability

by Mathias Nyman

USB 3.1 devices are not detected as 3.1 capable since 4.15-rc3 due to a off by one in commit 81cf4a45360f ("USB: core: Add type-specific length check of BOS descriptors") It uses USB_DT_USB_SSP_CAP_SIZE() to get SSP capability size which takes the zero based SSAC as argument, not the actual count of sublink speed attributes. USB3 spec 9.6.2.5 says "The number of Sublink Speed Attributes = SSAC + 1." The type-specific length check patch was added to stable and needs to be fixed there as well Fixes: 81cf4a45360f ("USB: core: Add type-specific length check of BOS descriptors") Cc: linux-stable <stable(a)vger.kernel.org> CC: Masakazu Mokuno <masakazu.mokuno(a)gmail.com> Signed-off-by: Mathias Nyman <mathias.nyman(a)linux.intel.com> --- drivers/usb/core/config.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/usb/core/config.c b/drivers/usb/core/config.c index 78e92d2..c821b4b 100644 --- a/drivers/usb/core/config.c +++ b/drivers/usb/core/config.c @@ -1007,7 +1007,7 @@ int usb_get_bos_descriptor(struct usb_device *dev) case USB_SSP_CAP_TYPE: ssp_cap = (struct usb_ssp_cap_descriptor *)buffer; ssac = (le32_to_cpu(ssp_cap->bmAttributes) & - USB_SSP_SUBLINK_SPEED_ATTRIBS) + 1; + USB_SSP_SUBLINK_SPEED_ATTRIBS); if (length >= USB_DT_USB_SSP_CAP_SIZE(ssac)) dev->bos->ssp_cap = ssp_cap; break; -- 2.7.4

[Linux-stable-mirror] [PATCH] tg3: Fix rx hang on MTU change with 5717/5719

by Brian King

This fixes a hang issue seen when changing the MTU size from 1500 MTU to 9000 MTU on both 5717 and 5719 chips. In discussion with Broadcom, they've indicated that these chipsets have the same phy as the 57766 chipset, so the same workarounds apply. This has been tested by IBM on both Power 8 and Power 9 systems as well as by Broadcom on x86 hardware and has been confirmed to resolve the hang issue.

[Linux-stable-mirror] patch "USB: chipidea: msm: fix ulpi-node lookup" added to usb-linus
