The check added to each non-object reads adds an overhead. If the
objects (binders and file descriptors) were written to the Parcel in
sequential order then check adds a small O(1) overhead to each read,
plus an O(N) overhead to the first read (to verify the N objects were
added in order).
If the objects were written out of order (as in by jumping around the
Parcel
with setDataPosition and writing Binder, DON'T DO THIS!!) (writing non
objects out of order is fine), the first read is forced to sort the
objects
in the internal bookkeeping. Based on the assumption non sequential
writes
are infrequent and overall Parcels are probably mostly sorted, insertion
sort was used. Worst case sorts will add an O(N^2) overhead to the first
non object read from the Parcel.

writeInplace() itself already pads securely, by masking off
the padded bytes. If the padding is done before calling
writeInplace(), no mask is applied, and heap data can leak.

This should be reverted when all system services have been cleaned up to not
do this. A process looking up a service while running in the background will
see the service registered by the active user (assuming the service is
registered on every user switch), not the service registered by the user that
the process itself belongs to.

The previous configuration sets target utilization as .25, which is geared towards
low memory devices. This path increases it to .75 and makes us pass the check:
(heaptargetutilization / 2) * heapsize = heapgrowthlimit
Example:
heapgrowthlimit: 256m
heapsize: 512m
heaptargetutilization: 0.75
0.75/2 * 512 = 192
To pass the check this has to be true:
192 = 256 (WRONG)
Check not passed.
This new configuration is optimized for higher RAM devices and passes the check:
heapgrowthlimit: 384m
heapsize: 1024m
heaptargetutilization: 0.75
0.75/2 * 1024 = 384
384 = 384 (TRUE)
Check passed.

The stylus eraser appeared not to work, i.e. Android did not respond to
input from the eraser. It turned out that all input except stylus input
is rejected when palm rejection is activated. The problem was that the
eraser itself activates palm rejection when it hovers. The solution is
to allow the eraser during palm rejection. This solution makes sense
because the eraser input works in the exact same way as normal stylus
input.

procrank is a setuid binary which only exists on userdebug/eng

the su command. This eliminates one more setuid binary, and allows

Pass the reference time to DispSyncThread. Since the phase offset is calculated
using timestamps relative to the reference time, we must also adjust the phase
offset by the same reference time when computing the next refresh time.
Always reset phase offset to zero when updating the reference time because the
reference time equals the first timestamp.
After beginResync() we need to keep HW vsync enabled until the model is updated.

Test: check in systrace that app/sf vsync events have correct phase
Do not use the absolute 64-bit nsecs_t timestamp directly in phase
and error calculations. Compared to the estimated vsync period, the
timestamp tend to many orders of magnitudes larger, and consequently
the integer modulo operation used to calculate phase and error can
be very sensitive to tiny fluctuation in vsync period.
