[ Upstream commit 02388bf87f72e1d47174cd8f81c34443920eb5a0 ]
In isdn_ppp_write(), the header (i.e., protobuf) of the buffer is
fetched twice from userspace. The first fetch is used to peek at the
protocol of the message and reset the huptimer if necessary; while the
second fetch copies in the whole buffer. However, given that buf resides
in userspace memory, a user process can race to change its memory content
across fetches. By doing so, we can either avoid resetting the huptimer
for any type of packets (by first setting proto to PPP_LCP and later
change to the actual type) or force resetting the huptimer for LCP
packets.
This patch changes this double-fetch behavior into two single fetches
decided by condition (lp->isdn_device < 0 || lp->isdn_channel <0).

[ Upstream commit ec9dd352d591f0c90402ec67a317c1ed4fb2e638 ]
This patch fixes a bug exhibited by the following scenario:
1. fd1 = perf_event_open with attr.config = ID1
2. attach bpf program prog1 to fd1
3. fd2 = perf_event_open with attr.config = ID1
<this will be successful>
4. user program closes fd2 and prog1 is detached from the tracepoint.
5. user program with fd1 does not work properly as tracepoint
no output any more.
The issue happens at step 4. Multiple perf_event_open can be called
successfully, but only one bpf prog pointer in the tp_event. In the
current logic, any fd release for the same tp_event will free
the tp_event->prog.
The fix is to free tp_event->prog only when the closing fd
corresponds to the one which registered the program.

Packet socket bind operations must hold the po->bind_lock. This keeps
po->running consistent with whether the socket is actually on a ptype
list to receive packets.
fanout_add unbinds a socket and its packet_rcv/tpacket_rcv call, then
binds the fanout object to receive through packet_rcv_fanout.
Make it hold the po->bind_lock when testing po->running and rebinding.
Else, it can race with other rebind operations, such as that in
packet_set_ring from packet_rcv to tpacket_rcv. Concurrent updates
can result in a socket being added to a fanout group twice, causing
use-after-free KASAN bug reports, among others.
Reported independently by both trinity and syzkaller.
Verified that the syzkaller reproducer passes after this patch.

[ Upstream commit f55956065ec94e3e9371463d693a1029c4cc3007 ]
This patch is pretty much a carbon copy of
commit 3079c65214 ("caif: Fix napi poll list corruption")
with "caif" replaced by "emac".
The commit d75b1ade56 ("net: less interrupt masking in NAPI")
breaks emac.
It is now required that if the entire budget is consumed when poll
returns, the napi poll_list must remain empty. However, like some
other drivers emac tries to do a last-ditch check and if there is
more work it will call napi_reschedule and then immediately process
some of this new work. Should the entire budget be consumed while
processing such new work then we will violate the new caller
contract.
This patch fixes this by not touching any work when we reschedule
in emac.

Now in ip6gre_header before packing the ipv6 header, it skb_push t->hlen
which only includes encap_hlen + tun_hlen. It means greh and inner header
would be over written by ipv6 stuff and ipv6h might have no chance to set
up.
Jianlin found this issue when using remote any on ip6_gre, the packets he
captured on gre dev are truncated:
22:50:26.210866 Out ethertype IPv6 (0x86dd), length 120: truncated-ip6 -\
8128 bytes missing!(flowlabel 0x92f40, hlim 0, next-header Options (0) \
payload length: 8192) ::1:2000:0 > ::1:0:86dd: HBH [trunc] ip-proto-128 \
8184
It should also skb_push ipv6hdr so that ipv6h points to the right position
to set ipv6 stuff up.
This patch is to skb_push hlen + sizeof(*ipv6h) and also fix some indents
in ip6gre_header.

This code causes a static checker warning because Smatch doesn't trust
anything that comes from skb->data. I've reviewed this code and I do
think skb->data can be controlled by the user here.
The sctp_event_subscribe struct has 13 __u8 fields and we want to see
if ours is non-zero. sn_type can be any value in the 0-USHRT_MAX range.
We're subtracting SCTP_SN_TYPE_BASE which is 1 << 15 so we could read
either before the start of the struct or after the end.
This is a very old bug and it's surprising that it would go undetected
for so long but my theory is that it just doesn't have a big impact so
it would be hard to notice.

Commit db8466c581cc ("MIPS: IRQ Stack: Unwind IRQ stack onto task
stack") erroneously set the initial stack pointer of the IRQ stack to a
value with a 4 byte alignment. The MIPS32 ABI requires that the minimum
stack alignment is 8 byte, and the MIPS64 ABIs(n32/n64) require 16 byte
minimum alignment. Fix IRQ_STACK_START such that it leaves space for the
dummy stack frame (containing interrupted task kernel stack pointer)
while also meeting minimum alignment requirements.

commit e88d62cd4b2f0b1ae55e9008e79c2794b1fc914d upstream.
As raw_cpu_generic_read() is a plain read from a raw_cpu_ptr() address,
it's possible (albeit unlikely) that the compiler will split the access
across multiple instructions.
In this_cpu_generic_read() we disable preemption but not interrupts
before calling raw_cpu_generic_read(). Thus, an interrupt could be taken
in the middle of the split load instructions. If a this_cpu_write() or
RMW this_cpu_*() op is made to the same variable in the interrupt
handling path, this_cpu_read() will return a torn value.
For native word types, we can avoid tearing using READ_ONCE(), but this
won't work in all cases (e.g. 64-bit types on most 32-bit platforms).
This patch reworks this_cpu_generic_read() to use READ_ONCE() where
possible, otherwise falling back to disabling interrupts.

Now it is save to restore the reverted upstream changes. Also
below upstream changes are coming with android@73a2b70 (4.4.92)
which will hit conflict if the above changes are not restored.

Remove declaration of function max_file_size(). It was added
with:
63ba8a3 BACKPORT: f2fs: add a max block check for get_data_block_bmap
On merging of android-4.4@d68ba9f (4.4.89) functional part of
the above change was replaced with the upstream's one, which do
not use max_file_size() and also this function was renamed to
max_file_blocks() in its definition with change c1286ff. In
android-4.4 this func was static, hence no declaration line in
f2fs.h and this is why it was left alone in msm-4.4 without to
be noticed.

In order to set rq->misfit_task in time, call update_task_ravg() prior
to task_tick. This reduces upmigration delay by 1 scheduler window.

At present, sched_freq_tick() skips updating of capacity update when
current frequency is fmax. This can cause incorrect frequency drop
when a CPU bound task goes into sleep for example :
1) A task (A) enqueues onto CPU 0 and executes for long time.
2) A new task (B) which has low task demand enqueues onto CPU 1 and
executes long so becomes a CPU bound task.
3) Both CPU 0 and 1 gets scheduler tick but skip sched_freq_tick()
since current frequency is fmax.
4) Task (A) sleeps and lower the CPU 0's capacity request.
5) Because task (B) voted CPU capacity at step 2 with low demand and
skipped to request afterwards, cluster frequency for both CPU 0
and 1 drops to match capacity voted by CPU 1 at step 2 even though
task (B) on CPU 1 requires max capacity.
Fix such incorrectness by not skipping CPU capacity voting at tick
path.

At present need_active_balance() determines whether an active
upmigration is needed by using capacity_of(). A CPU's capacity
may be reduced by RT pressure, and therefore distinguishing
capability differences with capacity_of() may lead to suboptimal
active migrations to less capable CPUs. Use capacity_orig_of
to distinguish differently capable CPUs in addition to
capacity_of(), thus avoiding placing tasks on less capable CPUs
due to instantaneous RT pressure.

There's no need for a separate hierarchy of notifiers, APIs
and variables in walt.c for the purpose of applying frequency
and IPC invariance. Let's just use capacity_curr_of and get
rid of a lot of the infrastructure relating to capacity,
load_scale_factor etc.

When both sides are doing DRP and the other side applies Rd near the end
of PMIC DFP cycle, sometimes, PMIC does not lock on into AttachedWait.SRC
and transitions back into Unattached.SNK.
If a resistance ranging (5.1k,300k) pulldown is applied and then 5.1kohms
pulldown is applied, then it takes 10-20ms to detect 5.1kohms.
Before this, if DRP.DFP time expires, then PMI transitions to UFP mode to
avoid extending DRP cycle time.
Fix it by extending DFP time. Note the total DRP time should still be
within max limit (100ms).

In Try.SNK software implementation, after forcing sink, there
is a delay of tDRPTRY + Tccdebounce time, giviing opportunity
to the other side to be a SRC.
The current delay is 100ms < tDRPTRY (90ms) + Tccdebounce (20ms),
too short, which sometimes results in checking Tccdebounce_done
status too early.
Change the delay to 120ms.

Try.SNK allows a DRP that has a policy based preference to be a Sink
when connecting to another DRP to effect a transition from a destined
Source role to the Sink role.
This is a Software implementation for PMI8998.
Exiting from AttachWait.SRC State, a DRP that strongly prefers the
Sink role may optionally transition to Try.SNK instead of Attached.SRC.
When in the Try.SNK state, the port is querying to determine if the
port partner supports the Source role.
The port shall then transition to Attached.SNK when the SNK.Rp state
is detected for at least tTryCCDebounce and VBUS is detected
Alternatively, the port shall transition to TryWait.SRC if SNK.Rp state
is not detected tTryCCDebounce.
The port shall transition to Attached.SRC when SRC.Rd state is detected
on exactly one of the CC pins.
The port shall transition to Unattached.SNK after tDRPTry if neither of
the CC1 or CC2 pins is in the SRC.Rd state.

Update the virtualized audio ION driver to add SMMU support.
The virtualized audio ION driver will provide the ION memory
allocated from the guest VM to the physical VM to perform SMMU
mapping.
The virtualized audio ION driver will receive SMMU mapped
device address from physical VM and provide the device address
to its clients. Upon its client frees the memory, the virtualized
audio ION driver will request the physical VM to perform SMMU
un-mapping.
