2018-04-12nfp: use full 40 bits of the NSP buffer addressDirk van der Merwe1-4/+5
[ Upstream commit 1489bbd10e16079ce30a53d3c22a431fd47af791 ] The NSP default buffer is a piece of NFP memory where additional command data can be placed. Its format has been copied from host buffer, but the PCIe selection bits do not make sense in this case. If those get masked out from a NFP address - writes to random place in the chip memory may be issued and crash the device. Even in the general NSP buffer case, it doesn't make sense to have the PCIe selection bits there anymore. These are unused at the moment, and when it becomes necessary, the PCIe selection bits should rather be moved to another register to utilise more bits for the buffer address. This has never been an issue because the buffer used to be allocated in memory with less-than-38-bit-long address but that is about to change.

[ Upstream commit bfacfb457b36911a10140b8cb3ce76a74883ac5a ] Once dst has been cached in socket via sk_setup_caps(), it is illegal to call ip_rt_put() (or dst_release()), since sk_setup_caps() did not change dst refcount. We can still dereference it since we hold socket lock.

2018-04-08vt: change SGR 21 to follow the standardsMike Frysinger1-1/+5
commit 65d9982d7e523a1a8e7c9af012da0d166f72fc56 upstream. ECMA-48 [1] (aka ISO 6429) has defined SGR 21 as "doubly underlined" since at least March 1984. The Linux kernel has treated it as SGR 22 "normal intensity" since it was added in Linux-0.96b in June 1992. Before that, it was simply ignored. Other terminal emulators have either ignored it, or treat it as double underline now. xterm for example added support in its 304 release (May 2014) [2] where it was previously ignoring it. Changing this behavior shouldn't be an issue: - It isn't a named capability in ncurses's terminfo database, so no script is using libtinfo/libcurses to look this up, or using tput to query & output the right sequence. - Any script assuming SGR 21 will reset intensity in all terminals already do not work correctly on non-Linux VTs (including running under screen/tmux/etc...). - If someone has written a script that only runs in the Linux VT, and they're using SGR 21 (instead of SGR 22), the output should still be readable. imo it's important to change this as the Linux VT's non-conformance is sometimes used as an argument for other terminal emulators to not implement SGR 21 at all, or do so incorrectly.

2018-04-08Input: i8042 - enable MUX on Sony VAIO VGN-CS series to fix touchpadOndrej Zary1-0/+17
commit 04bb1719c4de94700056241d4c0fe3c1413f5aff upstream. The touch sensor buttons on Sony VAIO VGN-CS series laptops (e.g. VGN-CS31S) are a separate PS/2 device. As the MUX is disabled for all VAIO machines by the nomux blacklist, the data from touch sensor buttons and touchpad are combined. The protocol used by the buttons is probably similar to the touchpad protocol (both are Synaptics) so both devices get enabled. The controller combines the data, creating a mess which results in random button clicks, touchpad stopping working and lost sync error messages: psmouse serio1: TouchPad at isa0060/serio1/input0 lost sync at byte 4 psmouse serio1: TouchPad at isa0060/serio1/input0 lost sync at byte 1 psmouse serio1: TouchPad at isa0060/serio1/input0 lost sync at byte 1 psmouse serio1: TouchPad at isa0060/serio1/input0 lost sync at byte 1 psmouse serio1: TouchPad at isa0060/serio1/input0 lost sync at byte 1 psmouse serio1: issuing reconnect request Add a new i8042_dmi_forcemux_table whitelist with VGN-CS.

2018-04-08Input: ALPS - fix TrackStick detection on Thinkpad L570 and Latitude 7370Masaki Ota1-3/+21
commit 567b9b549cfa1cbc202762ae97b5385c29ade1e3 upstream. The primary interface for the touchpad device in Thinkpad L570 is SMBus, so ALPS overlooked PS2 interface Firmware setting of TrackStick, and shipped with TrackStick otp bit is disabled. The address 0xD7 contains device number information, so we can identify the device by checking this value, but to access it we need to enable Command mode, and then re-enable the device. Devices shipped in Thinkpad L570 report either 0x0C or 0x1D as device numbers, if we see them we assume that the devices are DualPoints. The same issue exists on Dell Latitude 7370.

2018-04-08Revert "base: arch_topology: fix section mismatch build warnings"Gaku Inami1-6/+6
commit 9de9a449482677a75f1edd2049268a7efc40fc96 upstream. This reverts commit 452562abb5b7 ("base: arch_topology: fix section mismatch build warnings"). It causes the notifier call hangs in some use-cases. In some cases with using maxcpus, some of cpus are booted first and then the remaining cpus are booted. As an example, some users who want to realize fast boot up often use the following procedure. 1) Define all CPUs on device tree (CA57x4 + CA53x4) 2) Add "maxcpus=4" in bootargs 3) Kernel boot up with CA57x4 4) After kernel boot up, CA53x4 is booted from user When kernel init was finished, CPUFREQ_POLICY_NOTIFIER was not still unregisterd. This means that "__init init_cpu_capacity_callback()" will be called after kernel init sequence. To avoid this problem, it needs to remove __init{,data} annotations by reverting this commit. Also, this commit was needed to fix kernel compile issue below. However, this issue was also fixed by another patch: commit 82d8ba717ccb ("arch_topology: Fix section miss match warning due to free_raw_capacity()") in v4.15 as well. Whereas commit 452562abb5b7 added all the missing __init annotations, commit 82d8ba717ccb removed it from free_raw_capacity(). WARNING: vmlinux.o(.text+0x548f24): Section mismatch in reference from the function init_cpu_capacity_callback() to the variable .init.text:$x The function init_cpu_capacity_callback() references the variable __init $x. This is often because init_cpu_capacity_callback lacks a __init annotation or the annotation of $x is wrong.

2018-04-08crypto: ccp - return an actual key size from RSA max_size callbackMaciej S. Szmigiero1-4/+3
commit 0a9eb80e643064266868bd2fb2cd608e669309b0 upstream. rsa-pkcs1pad uses a value returned from a RSA implementation max_size callback as a size of an input buffer passed to the RSA implementation for encrypt and sign operations. CCP RSA implementation uses a hardware input buffer which size depends only on the current RSA key length, so it should return this key length in the max_size callback, too. This also matches what the kernel software RSA implementation does. Previously, the value returned from this callback was always the maximum RSA key size the CCP hardware supports. This resulted in this huge buffer being passed by rsa-pkcs1pad to CCP even for smaller key sizes and then in a buffer overflow when ccp_run_rsa_cmd() tried to copy this large input buffer into a RSA key length-sized hardware input buffer.

commit 50e7044535537b2a54c7ab798cd34c7f6d900bd2 upstream. Quoting the original report: It looks like there is a double-free vulnerability in Linux usbtv driver on an error path of usbtv_probe function. When audio registration fails, usbtv_video_free function ends up freeing usbtv data structure, which gets freed the second time under usbtv_video_fail label. usbtv_audio_fail: usbtv_video_free(usbtv); => v4l2_device_put(&usbtv->v4l2_dev); => v4l2_device_put => kref_put => v4l2_device_release => usbtv_release (CALLBACK) => kfree(usbtv) (1st time) usbtv_video_fail: usb_set_intfdata(intf, NULL); usb_put_dev(usbtv->udev); kfree(usbtv); (2nd time) So, as we have refcounting, use it Reported-by: Yavuz, Tuba <tuba@ece.ufl.edu> Signed-off-by: Oliver Neukum <oneukum@suse.com> CC: stable@vger.kernel.org Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

dm_get_bdev_for_ioctl()'s return of 0 or 1 must be the result from prepare_ioctl (1 means the ioctl was issued to a partition, 0 means it wasn't). Unfortunately commit 519049afea ("dm: use blkdev_get rather than bdgrab when issuing pass-through ioctl") reused the variable 'r' to store the return from blkdev_get() that follows prepare_ioctl() -- whereby dropping prepare_ioctl()'s result on the floor. This can lead to an ioctl or persistent reservation being issued to a partition going unnoticed, which implies the extra permission check for CAP_SYS_RAWIO is skipped. Fix this by using a different variable to store blkdev_get()'s return.

2018-03-29RDMA/ucma: Introduce safer rdma_addr_size() variantsRoland Dreier2-17/+33
There are several places in the ucma ABI where userspace can pass in a sockaddr but set the address family to AF_IB. When that happens, rdma_addr_size() will return a size bigger than sizeof struct sockaddr_in6, and the ucma kernel code might end up copying past the end of a buffer not sized for a struct sockaddr_ib. Fix this by introducing new variants int rdma_addr_size_in6(struct sockaddr_in6 *addr); int rdma_addr_size_kss(struct __kernel_sockaddr_storage *addr); that are type-safe for the types used in the ucma ABI and return 0 if the size computed is bigger than the size of the type passed in. We can use these new variants to check what size userspace has passed in before copying any addresses.
