2020-03-17arm64: smp: fix smp_send_stop() behaviourCristian Marussi
On a system with only one CPU online, when another one CPU panics while starting-up, smp_send_stop() will fail to send any STOP message to the other already online core, resulting in a system still responsive and alive at the end of the panic procedure.

2020-03-17USB: cdc-acm: fix rounding error in TIOCSSERIALAnthony Mallet
By default, tty_port_init() initializes those parameters to a multiple of HZ. For instance in line 69 of tty_port.c: port->close_delay = (50 * HZ) / 100; https://github.com/torvalds/linux/blob/master/drivers/tty/tty_port.c#L69 With e.g. CONFIG_HZ = 250 (as this is the case for Ubuntu 18.04 linux-image-4.15.0-37-generic), the default setting for close_delay is thus 125. When ioctl(fd, TIOCGSERIAL, &s) is executed, the setting returned in user space is '12' (125/10). When ioctl(fd, TIOCSSERIAL, &s) is then executed with the same setting '12', the value is interpreted as '120' which is different from the current setting and a EPERM error may be raised by set_serial_info() if !CAP_SYS_ADMIN. https://github.com/torvalds/linux/blob/master/drivers/usb/class/cdc-acm.c#L919 Fixes: ba2d8ce9db0a6 ("cdc-acm: implement TIOCSSERIAL to avoid blocking close(2)") Signed-off-by: Anthony Mallet <anthony.mallet@laas.fr> Cc: stable <stable@vger.kernel.org> Link: https://lore.kernel.org/r/20200312133101.7096-2-anthony.mallet@laas.fr Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2020-03-17usb: quirks: add NO_LPM quirk for RTL8153 based ethernet adaptersHans de Goede
We have been receiving bug reports that ethernet connections over RTL8153 based ethernet adapters stops working after a while with errors like these showing up in dmesg when the ethernet stops working: [12696.189484] r8152 6-1:1.0 enp10s0u1: Tx timeout [12702.333456] r8152 6-1:1.0 enp10s0u1: Tx timeout [12707.965422] r8152 6-1:1.0 enp10s0u1: Tx timeout This has been reported on Dell WD15 docks, Belkin USB-C Express Dock 3.1 docks and with generic USB to ethernet dongles using the RTL8153 chipsets. Some users have tried adding usbcore.quirks=0bda:8153:k to the kernel commandline and all users who have tried this report that this fixes this. Also note that we already have an existing NO_LPM quirk for the RTL8153 used in the Microsoft Surface Dock (where it uses a different usb-id). This commit adds a NO_LPM quirk for the generic Realtek RTL8153 0bda:8153 usb-id, fixing the Tx timeout errors on these devices.

2020-03-17CIFS: Increment num_remote_opens stats counter even in case of ↵Shyam Prasad N
smb2_query_dir_first The num_remote_opens counter keeps track of the number of open files which must be maintained by the server at any point. This is a per-tree-connect counter, and the value of this counter gets displayed in the /proc/fs/cifs/Stats output as a following... Open files: 0 total (local), 1 open on server ^^^^^^^^^^^^^^^^ As a thumb-rule, we want to increment this counter for each open/create that we successfully execute on the server. Similarly, we should decrement the counter when we successfully execute a close. In this case, an increment was being missed in case of smb2_query_dir_first, in case of successful open. As a result, we would underflow the counter and we could even see the counter go to negative after sufficient smb2_query_dir_first calls. I tested the stats counter for a bunch of filesystem operations with the fix. And it looks like the counter looks correct to me. I also check if we missed the increments and decrements elsewhere. It does not seem so. Few other cases where an open is done and we don't increment the counter are the compound calls where the corresponding close is also sent in the request.

2020-03-17staging: greybus: loopback_test: fix potential path truncationsJohan Hovold
Newer GCC warns about possible truncations of two generated path names as we're concatenating the configurable sysfs and debugfs path prefixes with a filename and placing the results in buffers of the same size as the maximum length of the prefixes. snprintf(d->name, MAX_STR_LEN, "gb_loopback%u", dev_id); snprintf(d->sysfs_entry, MAX_SYSFS_PATH, "%s%s/", t->sysfs_prefix, d->name); snprintf(d->debugfs_entry, MAX_SYSFS_PATH, "%sraw_latency_%s", t->debugfs_prefix, d->name); Fix this by separating the maximum path length from the maximum prefix length and reducing the latter enough to fit the generated strings. Note that we also need to reduce the device-name buffer size as GCC isn't smart enough to figure out that we ever only used MAX_STR_LEN bytes of it.

2020-03-17staging: mt7621-pci: use gpios for properly resetSergio Paracuellos
Original driver code was using three gpio's for reset asserts and deasserts the pcis. Instead of using that a general reset control with a perst gpio was introduced and it seems it is partially working but sometimes there are some unexpected hangs on boot. This commit make use of the three original gpios using 'reset-gpios' property of the device tree and removes the reset line and perst gpio. According to the mediatek aplication note v0.1 there are three gpios used for pcie ports reset control: gpio#19, gpio#8 and gpio#7 for slots 0, 1 and 2 respectively. This schema can be used separately for mt7621A but in some boards due to pin share issue, if the PCM and I2S function are enable at the same time, there are no enough GPIO to control per-port PCIe reset. In those cases gpio#19 is enought for reset the three ports together. Because of this we just try to get the three gpios but if some of them fail we are not failing in boot process, just prints a kernel notice and take after into account if the descriptor is or not valid in order to use it. All of them are set as GPIO output low configuration. The gpio descriptor's API takes device tree property into account and invert value if the pin is configured as active low. So we also have to properly request pins from device tree and set values correct in assert and deassert functions. After this changes the order to make all assert and deassert in the 'probe' process makes more sense: * Parse device tree. * make assert of the RC's and EP's before doing anything else. * make deassert of the RC's before initializing the phy. * Init the phy. * make deassert of the EP's before initialize pci ports. * Normal PCI initialization.
