tty/serial: digicolor: fix possible null-ptr-deref in digicolor_uart_probe()

2022-05-18T07:42:50+00:00

commit 447ee1516f19f534a228dda237eddb202f23e163 upstream. It will cause null-ptr-deref when using 'res', if platform_get_resource() returns NULL, so move using 'res' after devm_ioremap_resource() that will check it to avoid null-ptr-deref. And use devm_platform_get_and_ioremap_resource() to simplify code.

ping: fix address binding wrt vrf

2022-05-18T07:42:50+00:00

commit e1a7ac6f3ba6e157adcd0ca94d92a401f1943f56 upstream. When ping_group_range is updated, 'ping' uses the DGRAM ICMP socket, instead of an IP raw socket. In this case, 'ping' is unable to bind its socket to a local address owned by a vrflite. Before the patch: $ sysctl -w net.ipv4.ping_group_range='0 2147483647' $ ip link add blue type vrf table 10 $ ip link add foo type dummy $ ip link set foo master blue $ ip link set foo up $ ip addr add 192.168.1.1/24 dev foo $ ip addr add 2001::1/64 dev foo $ ip vrf exec blue ping -c1 -I 192.168.1.1 192.168.1.2 ping: bind: Cannot assign requested address $ ip vrf exec blue ping6 -c1 -I 2001::1 2001::2 ping6: bind icmp socket: Cannot assign requested address CC: stable@vger.kernel.org Fixes: 1b69c6d0ae90 ("net: Introduce L3 Master device abstraction") Signed-off-by: Nicolas Dichtel Reviewed-by: David Ahern Signed-off-by: Jakub Kicinski Signed-off-by: Nicolas Dichtel Signed-off-by: Greg Kroah-Hartman

MIPS: fix allmodconfig build with latest mkimage

2022-05-18T07:42:50+00:00

With the latest mkimage from U-Boot 2021.04+ the allmodconfig build fails. 822564cd3aa1 ("MIPS: generic: Update node names to avoid unit addresses") was applied for similar build failure, but it was not applied to 'arch/mips/generic/board-ocelot_pcb123.its.S' as that was removed from upstream when the patch was applied.

drm/vmwgfx: Initialize drm_mode_fb_cmd2

2022-05-18T07:42:50+00:00

commit 3059d9b9f6aa433a55b9d0d21b566396d5497c33 upstream. Transition to drm_mode_fb_cmd2 from drm_mode_fb_cmd left the structure unitialized. drm_mode_fb_cmd2 adds a few additional members, e.g. flags and modifiers which were never initialized. Garbage in those members can cause random failures during the bringup of the fbcon. Initializing the structure fixes random blank screens after bootup due to flags/modifiers mismatches during the fbcon bring up.

cgroup/cpuset: Remove cpus_allowed/mems_allowed setup in cpuset_init_smp()

2022-05-18T07:42:49+00:00

commit 2685027fca387b602ae565bff17895188b803988 upstream. There are 3 places where the cpu and node masks of the top cpuset can be initialized in the order they are executed: 1) start_kernel -> cpuset_init() 2) start_kernel -> cgroup_init() -> cpuset_bind() 3) kernel_init_freeable() -> do_basic_setup() -> cpuset_init_smp() The first cpuset_init() call just sets all the bits in the masks. The second cpuset_bind() call sets cpus_allowed and mems_allowed to the default v2 values. The third cpuset_init_smp() call sets them back to v1 values. For systems with cgroup v2 setup, cpuset_bind() is called once. As a result, cpu and memory node hot add may fail to update the cpu and node masks of the top cpuset to include the newly added cpu or node in a cgroup v2 environment. For systems with cgroup v1 setup, cpuset_bind() is called again by rebind_subsystem() when the v1 cpuset filesystem is mounted as shown in the dmesg log below with an instrumented kernel. [ 2.609781] cpuset_bind() called - v2 = 1 [ 3.079473] cpuset_init_smp() called [ 7.103710] cpuset_bind() called - v2 = 0 smp_init() is called after the first two init functions. So we don't have a complete list of active cpus and memory nodes until later in cpuset_init_smp() which is the right time to set up effective_cpus and effective_mems. To fix this cgroup v2 mask setup problem, the potentially incorrect cpus_allowed & mems_allowed setting in cpuset_init_smp() are removed. For cgroup v2 systems, the initial cpuset_bind() call will set the masks correctly. For cgroup v1 systems, the second call to cpuset_bind() will do the right setup. cc: stable@vger.kernel.org Signed-off-by: Waiman Long Tested-by: Feng Tang Reviewed-by: Michal Koutný Signed-off-by: Tejun Heo Signed-off-by: Greg Kroah-Hartman
