cred: allow get_cred() and put_cred() to be given NULL.

2021-10-06T08:23:43+00:00

commit f06bc03339ad4c1baa964a5f0606247ac1c3c50b upstream. It is common practice for helpers like this to silently, accept a NULL pointer. get_rpccred() and put_rpccred() used by NFS act this way and using the same interface will ease the conversion for NFS, and simplify the resulting code.

HID: betop: fix slab-out-of-bounds Write in betop_probe

2021-10-06T08:23:42+00:00

commit 1e4ce418b1cb1a810256b5fb3fd33d22d1325993 upstream. Syzbot reported slab-out-of-bounds Write bug in hid-betopff driver. The problem is the driver assumes the device must have an input report but some malicious devices violate this assumption. So this patch checks hid_device's input is non empty before it's been used.

arm64: Extend workaround for erratum 1024718 to all versions of Cortex-A55

2021-10-06T08:23:42+00:00

commit c0b15c25d25171db4b70cc0b7dbc1130ee94017d upstream. The erratum 1024718 affects Cortex-A55 r0p0 to r2p0. However we apply the work around for r0p0 - r1p0. Unfortunately this won't be fixed for the future revisions for the CPU. Thus extend the work around for all versions of A55, to cover for r2p0 and any future revisions.

ARM: 9098/1: ftrace: MODULE_PLT: Fix build problem without DYNAMIC_FTRACE

commit 6fa630bf473827aee48cbf0efbbdf6f03134e890 upstream FTRACE_ADDR is only defined when CONFIG_DYNAMIC_FTRACE is defined, the latter is even stronger requirement than CONFIG_FUNCTION_TRACER (which is enough for MCOUNT_ADDR).
