commit 75a2f31520095600f650597c0ac41f48b5ba0068 upstream.
This ioctl() implicitly assumed that the socket was already bound to
a valid local socket name, i.e. Phonet object. If the socket was not
bound, two separate problems would occur:
1) We'd send an pipe enablement request with an invalid source object.
2) Later socket calls could BUG on the socket unexpectedly being
connected yet not bound to a valid object.

commit b2f37aead1b82a770c48b5d583f35ec22aabb61e upstream.
The previous commit 3e0588c291d6 ("hamradio: defer ax25 kfree after
unregister_netdev") reorder the kfree operations and unregister_netdev
operation to prevent UAF.
This commit improves the previous one by also deferring the nullify of
the ax->tty pointer. Otherwise, a NULL pointer dereference bug occurs.
Partial of the stack trace is shown below.

commit 3e0588c291d6ce225f2b891753ca41d45ba42469 upstream.
There is a possible race condition (use-after-free) like below
(USE) | (FREE)
ax25_sendmsg |
ax25_queue_xmit |
dev_queue_xmit |
__dev_queue_xmit |
__dev_xmit_skb |
sch_direct_xmit | ...
xmit_one |
netdev_start_xmit | tty_ldisc_kill
__netdev_start_xmit | mkiss_close
ax_xmit | kfree
ax_encaps |
|
Even though there are two synchronization primitives before the kfree:
1. wait_for_completion(&ax->dead). This can prevent the race with
routines from mkiss_ioctl. However, it cannot stop the routine coming
from upper layer, i.e., the ax25_sendmsg.
2. netif_stop_queue(ax->dev). It seems that this line of code aims to
halt the transmit queue but it fails to stop the routine that already
being xmit.
This patch reorder the kfree after the unregister_netdev to avoid the
possible UAF as the unregister_netdev() is well synchronized and won't
return if there is a running routine.

commit 1ade48d0c27d5da1ccf4b583d8c5fc8b534a3ac8 upstream.
The existing cleanup routine implementation is not well synchronized
with the syscall routine. When a device is detaching, below race could
occur.
static int ax25_sendmsg(...) {
...
lock_sock()
ax25 = sk_to_ax25(sk);
if (ax25->ax25_dev == NULL) // CHECK
...
ax25_queue_xmit(skb, ax25->ax25_dev->dev); // USE
...
}
static void ax25_kill_by_device(...) {
...
if (s->ax25_dev == ax25_dev) {
s->ax25_dev = NULL;
...
}
Other syscall functions like ax25_getsockopt, ax25_getname,
ax25_info_show also suffer from similar races. To fix them, this patch
introduce lock_sock() into ax25_kill_by_device in order to guarantee
that the nullify action in cleanup routine cannot proceed when another
socket request is pending.

commit 890d5b40908bfd1a79be018d2d297cf9df60f4ee upstream.
When listening for notifications through netlink of a new interface being
registered, sporadically, it is possible for the MAC to be read as zero.
The zero MAC address lasts a short period of time and then switches to a
valid random MAC address.
This causes problems for netd in Android, which assumes that the interface
is malfunctioning and will not use it.
In the good case we get this log:
InterfaceController::getCfg() ifName usb0
hwAddr 92:a8:f0:73:79:5b ipv4Addr 0.0.0.0 flags 0x1002
In the error case we get these logs:
InterfaceController::getCfg() ifName usb0
hwAddr 00:00:00:00:00:00 ipv4Addr 0.0.0.0 flags 0x1002
netd : interfaceGetCfg("usb0")
netd : interfaceSetCfg() -> ServiceSpecificException
(99, "[Cannot assign requested address] : ioctl() failed")
The reason for the issue is the order in which the interface is setup,
it is first registered through register_netdev() and after the MAC
address is set.
Fixed by first setting the MAC address of the net_device and after that
calling register_netdev().

commit 66c915d09b942fb3b2b0cb2f56562180901fba17 upstream.
It's seems prone to problems by allowing card detect and its corresponding
mmc_rescan() work to run, during platform shutdown. For example, we may end
up turning off the power while initializing a card, which potentially could
damage it.
To avoid this scenario, let's add ->shutdown_pre() callback for the mmc host
class device and then turn of the card detect from there.

If the %r20 register is not clipped, a user process could perform a LWS call

commit 2dee54b289fbc810669a1b2b8a0887fa1c9a14d7 upstream.
Static analysis with scan-build has found an assignment to vp2 that is
never used. It seems that the check on vp->state > 0 should be actually
on vp2->state instead. Fix this.
This dates back to 2002, I found the offending commit from the git

TMP461 is almost identical to TMP451 and was actually detected as TMP451
with the existing lm90 driver if its I2C address is 0x4c. Add support
for it to the lm90 driver. At the same time, improve the chip detection
function to at least try to distinguish between TMP451 and TMP461.
As a side effect, this fixes commit 24333ac26d ("hwmon: (tmp401) use
smb word operations instead of 2 smb byte operations"). TMP461 does not
support word operations on temperature registers, which causes bad
temperature readings with the tmp401 driver. The lm90 driver does not
perform word operations on temperature registers and thus does not have
this problem.
Support is listed as basic because TMP461 supports a sensor resolution
of 0.0625 degrees C, while the lm90 driver assumes a resolution of 0.125
degrees C. Also, the TMP461 supports negative temperatures with its
default temperature range, which is not the case for similar chips
supported by the lm90 and the tmp401 drivers. Those limitations will be
addressed with follow-up patches.

The detect function had a comment "Make compiler happy" when id did not
read the second configuration register. As it turns out, the code was
checking the contents of this register for manufacturer ID 0xA1 (NXP
Semiconductor/Philips), but never actually read the register. So it
wasn't surprising that the compiler complained, and it indeed had a point.
Fix the code to read the register contents for manufacturer ID 0xa1.
At the same time, the code was reading the register for manufacturer ID
0x41 (Analog Devices), but it was not using the results. In effect it was
just checking if reading the register returned an error. That doesn't
really add much if any value, so stop doing that.

In commit 5648b5e1169f ("netfilter: nfnetlink_queue: fix OOB when mac
header was cleared"), the test for non-empty MAC header introduced in
commit 2c38de4c1f ("netfilter: fix looped (broad|multi)cast's MAC
handling") has been replaced with a test for a set MAC header.
This breaks the case when the MAC header has been reset (using
skb_reset_mac_header), as is the case with looped-back multicast
packets. As a result, the packets ending up in NFQUEUE get a bogus
hwaddr interpreted from the first bytes of the IP header.
This patch adds a test for a non-empty MAC header in addition to the
test for a set MAC header. The same two tests are also implemented in
nfnetlink_log.c, where the initial code of commit 2c38de4c1f
("netfilter: fix looped (broad|multi)cast's MAC handling") has not been
touched, but where supposedly the same situation may happen.

introduced support to use high baudrate with Fintek SuperIO UARTs. It'll
change clocksources when the UART probed.
But when user add kernel parameter "console=ttyS0,115200 console=tty0" to make
the UART as console output, the console will output garbled text after the
following kernel message.

The issue is occurs in following step:

It change clocksource from 115200 to 921600 with wrong time, it should change
