Files where stack protector is initialized should not be compiled with
stack protector enabled. This was done for Make but missing for CMake.
Fixes https://github.com/espressif/esp-idf/issues/2990.
Fix following WiFi bugs:
1. Fix the bug that STA incorrectly deletes BA when receiving DelBA request
2. Add out of memory check
3. Fix the bug that STA incorrectly receives packets when scanning in connected status
1. ref_clock used in unit tests occasionally produces time off by ~100
microseconds shortly after being started. Add a delay to let
ref_clock stabilise, until the cause is found.
2. Reduce roundoff error accumulation which would occasionally cause
the test to fail, by choosing an overflow value which can be divided
by APB frequency.
3. Move time sampling part of the test into an IRAM function to
reduce variations due to cache behavior.
4. Remove calculation of "standard deviation" in the test, as what was
calculated was not actually standard deviation, and it did not add any
useful information.
1. call esp_timer_get_time and ref_clock_get in the same order on
start and in the loop
2. disable interrupts when calculating delta between ref_clock
and esp_timer
3. ensure both functions are in cache before calculating the delta
The bug will cause memory corrupted (the largest range is from 0x3ffc0000 ~ 0x3ffc8000),
some strange error will happen, like IllegalInstruction, LoadProhibited and .etc.
Fix following WiFi bugs:
1. Fix a crash bug which is caused by WiFi static TX buffer alloc/free.
2. Fix the bug that iphone fails to connect to ESP32 AP by enabling AP BAR receiving.
3. Fix the bug that ESP32 station fails to connect some APs, such as Xiaomi hotspot etc,
after reset.
This commit adds the ability for backtracing to trace from the itnerrupt to the
task stack, and across nested interrupts. Test cases have also been added.
See merge request !4084
Note: "Test backtrace from abort" reset reason modified by removing abort as a reason.
Previously, hardware SHA engine "locks" were mutex semaphores. This meant that the task which
started a particular SHA session (in hardware) needed to finalise that session, or an invalid
FreeRTOS state was created.
Replace with binary semaphore which can be shared between tasks.
Includes a unit test, but unit test doesn't crash even without this fix
(some other unknown condition is required).
In some cases, linker could choose to use ROM functions instead of the
ones defined in IDF.
For functions used in ROM stub table, this would lead to infinite
recursion when the corresponding function was called from ROM.
For crypto functions, some of these were modified in IDF, and
incompatible with ROM counterparts.
If zero-overhead loop buffer is enabled, under certain rare conditions
when executing a zero-overhead loop, the CPU may attempt to execute an invalid instruction. Work around by disabling the buffer.
Due to a hardware limitation in ESP32, the first four bytes of some
CSI data is invalid, not the last four bytes.
Correct a mistake of CSI sub-carrier index in documentation.
1. fix bug PHY/RTC functions called in ISR (update phy to v4007)
2. add UnitTest to test it
3. fix task watchdog bug when wifi change channel
4. disable/enable agc to mac deinit/init
5. add UnitTest Job
state and reduce force receiving broadcast data time
1. If receiving beacon which indicates that there is no data
buffered, do not force to receive WiFi data.
2. If receiving beacon which indicates that there is broadcast data
buffered, reduce the time to force receiving broadcast data.
timer_process_alarm function of esp_timer holds a spinlock for the
entire duration of its operation, except for the time when timer
callback function is called. It is possible that when
timer_process_alarm releases the spinlock, a higher priority task may
run and delete the timer. Then the execution will return to
timer_process_alarm, and this will either cause a crash, or undesired
execution of callback after the timer has been stopped or deleted.
To solve this problem, add a mutex which will prevent deletion of timers
while callbacks are being dispatched.
This fix includes following changes:
1. Fix the bug that esp_restart()/esp_wifi_stop() sometimes fails in WiFi/BT coexist mode.
2. Add a timer for WiFi stop and stop WiFi forcibly once the timer expires.
1. start an esp_timer on entering sleep to acquire pm_lock before wake up from modem sleep
2. decrease the clock division of XTAL fed to bluetooth low power clock from 32us to 2us period to allow to work under 240MHz Max CPU frequency
3. decrease the minimum sleep duration threshold to allow shorter bluetooth modem sleep period, especially for BLE with short connection interval
4. reconfigure bluetooth baseband(BT-BB) settings after PHY/RF init upon waking up from modem sleep to avoid packet RX/TX performance degradation
1. Fix interrupt watchdog timeout in bluetooth "btdm_bb_isr"
2. Fix BLE assert(512) or assert(1536) in rwble.c at line 222
3. Update librtc.a to fix BLE assert(512) in rwble.c at line 222
The #1 and #2 occurs random.
The #3 bug occurs in certain scenario:
1. If Wifi start softap and BLE is working
2. If wifi start station, but do not use normal station operation, such
as just use espnow, while BLE is working
3. Any other scenario, that wifi works without use software coexist
operation, while BLE is working(such as do advertising and ...)
4. update libcoexist.a version to v1.1.2
This commit resolves a blocking in esp_aes_block function.
Introduce:
The problem was in the fact that AES is switched off at the moment when he should give out the processed data. But because of the disabled, the operation can not be completed successfully, there is an infinite hang. The reason for this behavior is that the registers for controlling the inclusion of AES, SHA, MPI have shared registers and they were not protected from sharing.
Fix some related issue with shared using of AES SHA RSA accelerators.
Closes: https://github.com/espressif/esp-idf/issues/2295#issuecomment-432898137
Fix some wifi bugs
1. Enable RX BAR
2. Fix the bug that ESP32 AP negotiates with iphone to 11g
3. Fix the bug that ESP32 STA has ap_loss because CMCC AP contains two SSID
1. When WIFI task or other high priority task blocks the Bluetooth task, ACL RX buffer will use up, ACL RX buffer ptr will point to null and will never point to a valid adress. Causing errors in Bluetooth.
2. hcimsgs.h used whether flow control is on or off
