Entry into recent versions of ARM Trusted Firmware will invalidate the CPU
branch predictor state in order to protect against aliasing attacks.
This patch exposes the PSCI "VERSION" function via psci_ops, so that it
can be invoked outside of the PSCI driver where necessary.

In order to invoke the CPU capability ->matches callback from the ->enable
callback for applying local-CPU workarounds, we need a handle on the
capability structure.
This patch passes a pointer to the capability structure to the ->enable
callback.

Currently we call the (optional) enable function for CPU _features_
only. As CPU _errata_ descriptions share the same data structure and
having an enable function is useful for errata as well (for instance
to set bits in SCTLR), lets call it when enumerating erratas too.

In the absence of commit a4298e4522d6 ("net: add SOCK_RCU_FREE socket
flag") and all the associated infrastructure changes to take advantage
of a RCU grace period before freeing, there is a heightened
possibility that a security check is performed while an ill-timed
setsockopt call races in from user space. It then is prudent to null
check sk_security, and if the case, reject the permissions.
Because of the nature of this problem, hard to duplicate, no clear
path, this patch is a simplified band-aid for stable trees lacking the
infrastructure for the series of commits leading up to providing a
suitable RCU grace period. This adjustment is orthogonal to
infrastructure improvements that may nullify the needed check, but
could be added as good code hygiene in all trees.

commit cbeef22fd611c4f47c494b821b2b105b8af970bb upstream.
Quoting Hans:
If we return 1 from our post_reset handler, then our disconnect handler
will be called immediately afterwards. Since pre_reset blocks all scsi
requests our disconnect handler will then hang in the scsi_remove_host
call.
This is esp. bad because our disconnect handler hanging for ever also
stops the USB subsys from enumerating any new USB devices, causes commands
like lsusb to hang, etc.
In practice this happens when unplugging some uas devices because the hub
code may see the device as needing a warm-reset and calls usb_reset_device
before seeing the disconnect. In this case uas_configure_endpoints fails
with -ENODEV. We do not want to print an error for this, so this commit
also silences the shost_printk for -ENODEV.
ENDQUOTE
However, if we do that we better drop any unconditional execution
and report to the SCSI subsystem that we have undergone a reset
but we are not operational now.

commit ce5bf9a50daf2d9078b505aca1cea22e88ecb94a upstream.
Upon usb composition switch there is possibility of ep0 file
release happening after gadget driver bind. In case of composition
switch from adb to a non-adb composition gadget will never gets
bound again resulting into failure of usb device enumeration. Fix
this issue by checking FFS_FL_BOUND flag and avoid extra
gadget driver unbind if it is already done as part of composition
switch.
This fixes adb reconnection error reported on Android running
v4.4 and above kernel versions. Verified on Hikey running vanilla
v4.15-rc7 + few out of tree Mali patches.

commit ef54cf0c600fb8f5737fb001a9e357edda1a1de8 upstream.
usbip host binds to devices attached to vhci_hcd on the same server
when user does attach over localhost or specifies the server as the
remote.
usbip attach -r localhost -b busid
or
usbip attach -r servername (or server IP)
Unbind followed by bind works, however device is left in a bad state with
accesses via the attached busid result in errors and system hangs during
shutdown.
Fix it to check and bail out if the device is already attached to vhci_hcd.

commit c7b8f77872c73f69a16528a9eb87afefcccdc18b upstream.
According to drivers/usb/serial/io_edgeport.c, the driver may sleep
under a spinlock.
The function call path is:
edge_bulk_in_callback (acquire the spinlock)
process_rcvd_data
process_rcvd_status
change_port_settings
send_iosp_ext_cmd
write_cmd_usb
usb_kill_urb --> may sleep
To fix it, the redundant usb_kill_urb() is removed from the error path
after usb_submit_urb() fails.
This possible bug is found by my static analysis tool (DSAC) and checked
by my code review.

[ Upstream commit b77992d2df9e47144354d1b25328b180afa33442 ]
When not associated with an AP, wifi device drivers should respond to the
SIOCGIWESSID ioctl with a zero-length string for the SSID, which is the
behavior expected by dhcpcd.
Currently, this driver returns an error code (-1) from the ioctl call,
which causes dhcpcd to assume that the device is not a wireless interface
and therefore it fails to work correctly with it thereafter.
This problem was reported and tested at

[ Upstream commit e4717292ddebcfe231651b5aff9fa19ca158d178 ]
As part of the scsi EH path, aacraid performs a reinitialization of the
adapter, which encompass freeing resources and IRQs, NULLifying lots of
pointers, and then initialize it all over again. We've identified a
problem during the free IRQ portion of this path if CONFIG_DEBUG_SHIRQ
is enabled on kernel config file.
Happens that, in case this flag was set, right after free_irq()
effectively clears the interrupt, it checks if it was requested as
IRQF_SHARED. In positive case, it performs another call to the IRQ
handler on driver. Problem is: since aacraid currently free some
resources *before* freeing the IRQ, once free_irq() path calls the
handler again (due to CONFIG_DEBUG_SHIRQ), aacraid crashes due to NULL
pointer dereference with the following trace:
aac_src_intr_message+0xf8/0x740 [aacraid]
__free_irq+0x33c/0x4a0
free_irq+0x78/0xb0
aac_free_irq+0x13c/0x150 [aacraid]
aac_reset_adapter+0x2e8/0x970 [aacraid]
aac_eh_reset+0x3a8/0x5d0 [aacraid]
scsi_try_host_reset+0x74/0x180
scsi_eh_ready_devs+0xc70/0x1510
scsi_error_handler+0x624/0xa20
This patch prevents the crash by changing the order of the
deinitialization in this path of aacraid: first we clear the IRQ, then
we free other resources. No functional change intended.
