ba64c39c8caa2f04f3d78765b48d661b7e9d19ee 17-Jun-2016 Pavlin Radoslavov <pavlin@google.com> Add missing NULL pointers assignments

Each pointer that was freed by one of the following functions should
be reset to NULL:
- config_free()
- data_dispatcher_free()
- fixed_queue_free()
- list_free()

9ccca2b5937ec42409d8b6354884f1f4b6d524f7 18-Mar-2016 Andre Eisenbach <eisenbach@google.com> Do not leak eventfd's for RFCOMM/AVDT/L2CAP

Various users of fixed_queue's do not free the lists properly after
using them. As a result two event fd's leak for each fixed_queue that
is not free'd, as fixed_queue contains two semaphores.

This can lead to run-away file descriptor allocation and an eventual
hard limit leading to various undefined behaviours.

abd70abb5e42c9431df94fe9d2c4a78a0d8d9af9 05-Feb-2016 Pavlin Radoslavov <pavlin@google.com> Replaced osi_getbuf()/osi_freebuf() with osi_malloc()/osi_free()

Removed the alternative buffer allocation osi_getbuf() / osi_freebuf()
and use instead osi_malloc() / osi_free().

Correspondingly, replaced usage of osi_freebuf_and_reset()
with osi_free_and_reset().

78bcff79e1b1f0efce436b33bdd6da88745bfc8a 05-Dec-2015 Pavlin Radoslavov <pavlin@google.com> Refactor the Bluetooth timers

* Updated the alarm API:
- Existing API alarm_new() is modified to take an alarm name
as an argument.
- New API alarm_new_periodic() is used to create a periodic
alarm.
- Added new API alarm_is_scheduled() to test whether an alarm is
scheduled.
- Existing API alarm_set_periodic() is removed: a periodic
alarm is created by alarm_new_periodic().
- Added new API alarm_set_on_queue() to set an alarm whose
callback is executed on a specific queue.
- Added new API alarm_register_processing_queue() and
alarm_unregister_processing_queue() to register/unregister
a queue and the corresponding thread for alarm processing.
- Added corresponding unit tests.

* Updated the alarm internals:
- Added alarm_info_t for collecting alarm-related information
and statistics.
- Collect and store alarm-related statistics into alarm_info_t
per alarm.
- Include the alarm-related statistics and info into the native
dumpsys output for Bluetooth.
- Once an alarm expires, the alarm execution is scheduled for
processing on another internal alarm-specific thread, not
on the thread that is maintaining the alarms.
- Implemented callback execution ordering guarantee among
timers on the same thread with exactly same timeout values.

* Refactor some of the usage of alarm_set() and simplify the
code by using alarm_set_on_queue() instead.

* Removed the non_repeating timers wrapper, and use directly
the alarm mechanism / API.

* Refactored all timer_entry_t timers and replaced them with alarm_t
timers:
- Replaced the btu_start_timer() / btu_stop_timer() /
btu_start_quick_timer() / btu_stop_quick_timer() /
btu_oneshot_alarm() mechanism with alarm_set_on_queue() and
alarm_cancel()
- Removed the whole mechanism around the BTU_TTYPE_* timers.

* Fixed a bug when processing the GATT indication confirmation timer
expiration (timer tGATT_TCB.conf_timer: b/26610829).

* Renamed and/or split misc. timeout functions, fields, and timers

* Renamed time-related constants and changed the values from seconds
to milliseconds

* Replaced timer tAVDT_CCB.timer_entry with three mutually exclusive timers:
idle_ccb_timer, ret_ccb_timer, rsp_ccb_timer
The reason we are using three timers, is because in the original code
function avdt_ccb_chk_timer() used the timer type in its logic: it
would stop the timer only if the type is "idle".

* Removed btm_ble_timeout() and replaced it with multiple timeout
callback functions (per timer)

* Fix the actual value of the global constant BT_1SEC_TIMEOUT and
rename it to BT_1SEC_TIMEOUT_MS

* Removed btu_cb and associated timers and events, because they are
never used.

* Removed unused timers, functions, struct and declarations that are
not used / needed.

Removed macros PORT_SCHEDULE_LOCK and PORT_SCHEDULE_UNLOCK
and replaced them with direct calls to mutex_global_lock()
and mutex_global_unlock() respectively.

* Moved the following GKI buffer allocation functions to OSI:
- GKI_getbuf() -> osi_getbuf()
- GKI_freebuf() -> osi_freebuf()
- GKI_get_buf_size() -> osi_get_buf_size()

For now we need the osi_getbuf() / osi_freebuf() allocation wrapper,
because we need to be able to call osi_get_buf_size() on the allocated
buffer.
In the future those should be replaced with osi_malloc() / osi_free().
Currently, the osi_malloc() buffer size internal allocation tracker
does not always track the size, hence we need the osi_getbuf() wrapper.

* Replaced GKI_MAX_BUF_SIZE with BT_DEFAULT_BUFFER_SIZE

* Added new file include/bt_common.h that can be usee to include
few files that should be included alost everywhere (e.g. bt_target.h"
NOTE: This file might be removed in the future and we should include
everywhere the right set of header files.

* Removed some of the GKI-related references

* Removed file include/gki_target.h

1a3844f933bd63c8a381371dabfb35c6a0249e3e 25-Sep-2015 Pavlin Radoslavov <pavlin@google.com> GKI cleanup - Replaced usage of GKI queue with OSI fixed_queue

* Added new functions to OSI:
- fixed_queue_init()
- fixed_queue_length()
- fixed_queue_try_remove_from_queue()
- fixed_queue_try_peek_last()

* Renamed fixed_queue_try_peek() to fixed_queue_try_peek_first()

* Replaced usage of GKI queue functions with OSI fixed_queue functions:
- GKI_init_q() -> fixed_queue_new(SIZE_MAX)
NOTE: unlike GKI_init_q(), fixed_queue_new() allocates memory /
state that needs to be released by calling fixed_queue_free()
- GKI_enqueue() -> fixed_queue_enqueue()
- GKI_dequeue() -> fixed_queue_try_dequeue()
NOTE: fixed_queue_try_dequeue() is non-blocking
- GKI_queue_length() -> fixed_queue_length()
- GKI_queue_is_empty() -> fixed_queue_is_empty()
- GKI_getfirst() -> fixed_queue_try_peek_first()
- GKI_getlast() -> fixed_queue_try_peek_last()
- GKI_remove_from_queue() -> fixed_queue_try_remove_from_queue()
- Queue elements iteration.
In the fixed_queue implementation we have to use the underlying
list_t mechanism to iterate over the elements.
OLD:
p = GKI_getfirst(queue);
...
while ((p = GKI_getnext(p) != NULL) {
...
}
NEW:
list_t *list = fixed_queue_get_list(queue);
for (const list_node_t *node = list_begin(list);
node != list_end(list); node = list_next(node)) {
p = list_node(node);
}

* Remove initialization of the GKI module, because it is not needed
anymore

* Removed unused files in GKI:
gki/common/gki_common.h
gki/ulinux/gki_int.h
gki/ulinux/gki_ulinux.c
