There is a possibility of sharing process_private between two unrelated
processes due to PID wrapping. In kgsl_process_private_new(), instead
of checking numeric TGID, compare the unique pid pointer of the current
process with that of the existing processes in kgsl process list to
allow sharing of process_private data judiciously. Also, in all required
functions get TGID/PID of a process from its struct pid.

The process mutex is held while removing the sysfs nodes, which
waits for any access to finish before completion. If another thread
does a read at the same time, it will wait for the process mutex
which is already being held by the first thread, causing a deadlock.
Get a refcount to the process private to make sure that it is valid
while the sysfs nodes exist. This removes the need to hold the
process mutex while reading the nodes.

commit 4f3882177240a1f55e45a3d241d3121341bead78 upstream.
We should not be leaving half-mapped usages with potentially invalid
keycodes, as that may confuse hidinput_find_key() when the key is located
by index, which may end up feeding way too large keycode into the VT
keyboard handler and cause OOB write there:

commit ed9be64eefe26d7d8b0b5b9fa3ffdf425d87a01f upstream.
The HID subsystem allows an "HID report field" to have a different
number of "values" and "usages" when it is allocated. When a field
struct is created, the size of the usage array is guaranteed to be at
least as large as the values array, but it may be larger. This leads to
a potential out-of-bounds write in
__hidinput_change_resolution_multipliers() and an out-of-bounds read in
hidinput_count_leds().
To fix this, let's make sure that both the usage and value arrays are
the same size.

A sock_tag_entry can only be part of one process's
pqd_entry->sock_tag_list. Retagging the socket only updates
sock_tag_entry->tag, and does not add the tag entry to the current
process's pqd_entry list, nor update sock_tag_entry->pid.
So the sock_tag_entry is only ever present in the
pqd_entry list of the process that initially tagged the socket.
A sock_tag_entry can also get created and not be added to any process's
pqd_entry list. This happens if the process that initially tags the
socket has not opened /dev/xt_qtaguid.
ctrl_cmd_untag() supports untagging from a context other than the
process that initially tagged the socket. Currently, the sock_tag_entry is
only removed from its containing pqd_entry->sock_tag_list if the
process that does the untagging has opened /dev/xt_qtaguid. However, the
tag entry should always be deleted from its pqd entry list (if present).

To prevent protential risk of memory leak caused by closing socket with
out untag it from qtaguid module, the qtaguid module now do not hold any
socket file reference count. Instead, it will increase the sk_refcnt of
the sk struct to prevent a reuse of the socket pointer. And when a socket
is released. It will delete the tag if the socket is previously tagged so
no more resources is held by xt_qtaguid moudle. A flag is added to the untag
process to prevent possible kernel crash caused by fail to delete
corresponding socket_tag_entry list.

In the API, the driver inserts 0 after the SSID name, to mark the
end of the ssid, but if the SSID name is 32 characters which is
the max SSID length possible, the driver puts 0 at the 33rd
place of memory which is not the part of the SSID name, which
results in OOB write, or off-by-one write condition.
Fix is to remove the addition of 0 after ssid, as in every
case the driver prints the ssid, taking the ssid length
as the input, and in that case insertion of 0 will not serve
any purpose.
