9f614197c7 drm/msm: Use the correct dma_sync calls harder 
Looks like the dma_sync calls don't do what we want on armv7 either.

e5bfad3d7a smack: use GFP_NOFS while holding inode_smack::smk_lock 
inode_smack::smk_lock is taken during smack_d_instantiate(), which is
called during a filesystem transaction when creating a file on ext4.
Therefore to avoid a deadlock, all code that takes this lock must use
GFP_NOFS, to prevent memory reclaim from waiting for the filesystem
transaction to complete.

3f4287e7d9 security: smack: Fix possible null-pointer dereferences in smack_socket_sock_rcv_skb() 
In smack_socket_sock_rcv_skb(), there is an if statement
on line 3920 to check whether skb is NULL:
    if (skb && skb->secmark != 0)

This check indicates skb can be NULL in some cases.

But on lines 3931 and 3932, skb is used:
    ad.a.u.net->netif = skb->skb_iif;
    ipv6_skb_to_auditdata(skb, &ad.a, NULL);

Thus, possible null-pointer dereferences may occur when skb is NULL.

To fix these possible bugs, an if statement is added to check skb.

These bugs are found by a static analysis tool STCheck written by us.

3675f052b4 Smack: Don't ignore other bprm->unsafe flags if LSM_UNSAFE_PTRACE is set 
There is a logic bug in the current smack_bprm_set_creds():
If LSM_UNSAFE_PTRACE is set, but the ptrace state is deemed to be
acceptable (e.g. because the ptracer detached in the meantime), the other
->unsafe flags aren't checked. As far as I can tell, this means that
something like the following could work (but I haven't tested it):

 - task A: create task B with fork()
 - task B: set NO_NEW_PRIVS
 - task B: install a seccomp filter that makes open() return 0 under some
   conditions
 - task B: replace fd 0 with a malicious library
 - task A: attach to task B with PTRACE_ATTACH
 - task B: execve() a file with an SMACK64EXEC extended attribute
 - task A: while task B is still in the middle of execve(), exit (which
   destroys the ptrace relationship)

Make sure that if any flags other than LSM_UNSAFE_PTRACE are set in
bprm->unsafe, we reject the execve().

3dd550a2d3 USB: usbcore: Fix slab-out-of-bounds bug during device reset 
The syzbot fuzzer provoked a slab-out-of-bounds error in the USB core:

The error occurs when the descriptors_changed() routine (called during
a device reset) attempts to compare the old and new BOS and capability
descriptors.  The length it uses for the comparison is the
wTotalLength value stored in BOS descriptor, but this value is not
necessarily the same as the length actually allocated for the
descriptors.  If it is larger the routine will call memcmp() with a
length that is too big, thus reading beyond the end of the allocated
region and leading to this fault.

The kernel reads the BOS descriptor twice: first to get the total
length of all the capability descriptors, and second to read it along
with all those other descriptors.  A malicious (or very faulty) device
may send different values for the BOS descriptor fields each time.
The memory area will be allocated using the wTotalLength value read
the first time, but stored within it will be the value read the second
time.

To prevent this possibility from causing any errors, this patch
modifies the BOS descriptor after it has been read the second time:
It sets the wTotalLength field to the actual length of the descriptors
that were read in and validated.  Then the memcpy() call, or any other
code using these descriptors, will be able to rely on wTotalLength
being valid.

3b1261fb72 bus: imx-weim: remove incorrect __init annotations 
The probe function is no longer __init, so anything it calls now
must also be available at runtime, as Kbuild points out when building
with clang-9:

WARNING: vmlinux.o(.text+0x6e7040): Section mismatch in reference from the function weim_probe() to the function .init.text:imx_weim_gpr_setup()
The function weim_probe() references
the function __init imx_weim_gpr_setup().
This is often because weim_probe lacks a __init
annotation or the annotation of imx_weim_gpr_setup is wrong.

WARNING: vmlinux.o(.text+0x6e70f0): Section mismatch in reference from the function weim_probe() to the function .init.text:weim_timing_setup()
The function weim_probe() references
the function __init weim_timing_setup().
This is often because weim_probe lacks a __init
annotation or the annotation of weim_timing_setup is wrong.

Remove the remaining __init markings that are now wrong.
