2020-07-15Bluetooth: Add per-instance adv disable/removeDaniel Winkler
Add functionality to disable and remove advertising instances, and use that functionality in MGMT add/remove advertising calls. Currently, advertising is globally-disabled, i.e. all instances are disabled together, even if hardware offloading is available. This patch adds functionality to disable and remove individual adv instances, solving two issues: 1. On new advertisement registration, a global disable was done, and then only the new instance was enabled. This meant only the newest instance was actually enabled. 2. On advertisement removal, the structure was removed, but the instance was never disabled or removed, which is incorrect with hardware offload support.

ERR_NX_TRANSLATION(CSB.CC=5) is for internal to VAS for fault handling and should not used by OS. ERR_NX_AT_FAULT(CSB.CC=250) is the proper error code should be reported by OS when NX encounters address translation failure.

2020-07-15powerpc/vas: Report proper error code for address translation failureHaren Myneni
P9 DD2 NX workbook (Table 4-36) says DMA controller uses CC=5 internally for translation fault handling. NX reserves CC=250 for OS to notify user space when NX encounters address translation failure on the request buffer. Not an issue in earlier releases as NX does not get faults on kernel addresses. This patch defines CSB_CC_FAULT_ADDRESS(250) and updates CSB.CC with this proper error code for user space.

2020-07-15fuse: Fix parameter for FS_IOC_{GET,SET}FLAGSChirantan Ekbote
The ioctl encoding for this parameter is a long but the documentation says it should be an int and the kernel drivers expect it to be an int. If the fuse driver treats this as a long it might end up scribbling over the stack of a userspace process that only allocated enough space for an int. This was previously discussed in [1] and a patch for fuse was proposed in [2]. From what I can tell the patch in [2] was nacked in favor of adding new, "fixed" ioctls and using those from userspace. However there is still no "fixed" version of these ioctls and the fact is that it's sometimes infeasible to change all userspace to use the new one. Handling the ioctls specially in the fuse driver seems like the most pragmatic way for fuse servers to support them without causing crashes in userspace applications that call them.

2020-07-15rtw88: coex: Fix ACL Tx pause during BT inquiry/page.Zong-Zhe Yang
Add a set of logic with corresponding coexistence parameters to handle the situation under BT inquiry/page. We will set PSTDMA while WL-Busy + BT inquiry/page to separate WL/BT slots. PSTDMA can protect WL data rate and BT performance. If WL-Busy + BT inquiry/page and there was BT device paired, We will set the mechanism to 4Slot PSTDMA. In 4Slot PSTDMA, the paired devices can perform more smoothly and prevent some issues trigger from insufficient data. And to avoid A2DP glitch or disconnection, we will adjust ACL data priority higher than inquiry/page. In addition, we found sometimes BT inquiry/page still working last for seconds after BT had notified inquiry/page finished. It will lead to A2DP glitch cause of ACL data, inquiry/page priority toggled. To fix the corner, we add a timer to remain the inquiry/page status. And we found WL busy/idle threshold is too sensitive, it will keep switching in some weak network environment and coexistence mechanism will switch between TDMA and PSTDMA. The very frequently switching may destroyed not only the handshake with AP, but BT performance. And it will trigger some unexpected error. To prevent the frequently switching, we add a timer to delay the status change while WL busy switch to idle.

2020-07-15mwifiex: Fix reporting 'operation not supported' error codePali Rohár
ENOTSUPP (double PP) is internal linux kernel code 524 available only in kernel include file linux/errno.h and not exported to userspace. EOPNOTSUPP (OP; double PP) is standard code 95 for reporting 'operation not supported' available via kernel include file uapi/asm-generic/errno.h. ENOTSUP (single P) is alias for EOPNOTSUPP defined only in userspace include file bits/errno.h and not available in kernel. Because Linux kernel does not support ENOTSUP (single P) and because userspace does not support ENOTSUPP (double PP), report error code for 'operation not supported' via EOPNOTSUPP macro. This patch fixes problem that mwifiex kernel driver sends to userspace unsupported error codes like: "failed: -524 (No error information)".

2020-07-15Revert "thermal: mediatek: fix register index error"Enric Balletbo i Serra
This reverts commit eb9aecd90d1a39601e91cd08b90d5fee51d321a6 The above patch is supposed to fix a register index error on mt2701. It is not clear if the problem solved is a hang or just an invalid value returned, my guess is the second. The patch introduces, though, a new hang on MT8173 device making them unusable. So, seems reasonable, revert the patch because introduces a worst issue. The reason I send a revert instead of trying to fix the issue for MT8173 is because the information needed to fix the issue is in the datasheet and is not public. So I am not really able to fix it. Fixes the following bug when CONFIG_MTK_THERMAL is set on MT8173 devices.

2020-07-15wlcore: Use spin_trylock in wlcore_irq() to see if we need to queue txTony Lindgren
We currently have a collection of flags and locking between the threaded irq and tx work: - wl->flags bitops - wl->mutex - wl->wl_lock spinlock The bitops flags do not need a spinlock around them, and we only need the spinlock to see if we need to queue tx work or not. And wlcore_irq() holds the mutex. To simplify the locking, we can use spin_trylock and always queue tx work unless we know there's nothing to do. Let's also update the comment a bit while at it.

2020-07-15wlcore: Simplify runtime resume ELP pathTony Lindgren
We can simplify the runtime resume ELP path by always setting and clearing the completion in runtime resume. This way we can test for WL1271_FLAG_IRQ_RUNNING after the resume write to see if we need completion at all. And in wlcore_irq(), we need to take spinlock for running the completion and for the pm_wakeup_event(). Spinlock is not needed around the bitops flags check for WL1271_FLAG_SUSPENDED so the spinlocked sections get shorter.

2020-07-15rtw88: pci: disable aspm for platform inter-op with module parameterYan-Hsuan Chuang
Some platforms cannot read the DBI register successfully for the ASPM settings. After the read failed, the bus could be unstable, and the device just became unavailable [1]. For those platforms, the ASPM should be disabled. But as the ASPM can help the driver to save the power consumption in power save mode, the ASPM is still needed. So, add a module parameter for them to disable it, then the device can still work, while others can benefit from the less power consumption that brings by ASPM enabled.
