Issue: MDNS server initially sends probing packets to resolve naming confilicts with already registered service instances. In case of a conflict, instance name is altered and probing restarts. Original instance however wasnnot removed from the structure and upon service removal only one entry was removed and a dangling service might have been kept in the structure to bring about a crash.
Resolution: Keep only one instance of a service in the probing structure.
Closes IDF-438
possible race condition: user task runs mdns_init, which enables pcbs while mdns-task already created could execute enable/disable of the same pcbs if an appropriate system event received
mnds_free() initiates stop and delete timer tasks, which after locking the mutex could lead to a dead lock in case timer task executed before deleting the task, as it would wait indefinitelly for unlocking the mutex. This condition is fixed by calling _mdns_stop_timer without locking the mutex, because there's no need to protect any data when stopping and deleting the timer task
Closes https://github.com/espressif/esp-idf/issues/1696
Issue: mdns_service_add API allocates and queues an action to be processed in mdns task context; when allocation or queueing fails, allocated structure needs to be freed. Function _mdns_free_service did not only fee all the structures, but also updates packet data.
Resolution: Moved removal of packet data outside of _mdns_free_service function.
packets scheduled to transmit are pushed to action queue and removed from tx_queue_head structure, which is searched for all remaining services and while service is removed, then service questions/asnwers are also removed from this structure. This update fixes possible crash when packet is pushed to action queue, and when service is removed, its answers are removed from tx_queue_head, but not from action queue. this could lead to a crash when the packet is poped from action queue containing questions/answers to already removed (freed) service
Closes IDF-438
mdns_search_once_t::lock is used to synchronize tasks (taken by one
task and given by the other) so it should not be a mutex.
Convert to semaphore, and rename to indicate its purpose.
By default, if a URI handler changes the http session context,
the webserver internally clears the older context after the handler
returns. However, if applications want to change this behavior and
manage the allocation/de-allocation/freeing themselves and let the
server handle only the "socket close" case, this commit provides such
an option.
When xPortGetCoreID() is called twice within a function,
it might only be called once after compilation. This
commit makes the inline assembly of the function volatile.

Previously when HashList was removing items, HashListBlocks were
removed lazily. This resulted in empty HashListBlocks dangling around
in full pages, even when all items have been erased. These blocks
would only be deleted when NVS was re-initialized
(nvs_flash_deinit/nvs_flash_init).
This change does eager cleanup instead, based on the code from
@negativekelvin offered in
https://github.com/espressif/esp-idf/issues/1642#issuecomment-367227994.
Closes https://github.com/espressif/esp-idf/issues/1642.
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
In the situation when bootloader was compiled for 240MHz, and app was
compiled for 160MHz, and the chip is a revision 0 chip, the
bootloader will assume that the application has also been running at
240MHz. This will cause the chip to lock up later. Modify this to use
a run time check of DPORT_CPUPERIOD_SEL, which indicates which of the
PLL frequencies was used.

2. do BLE scan stop or adv stop or connection stop, it might cause ASSERT or crash due to memory corrupted in controller memory poll.
3. minor bug fix, not really effect bluetooth.
when running a query for a single txt, result entries were not created and attached to result structure. this issue was introduced when fixing memory leak in txt structure, which worked correctly for PTR queries, but caused trouble for TXT query.
The bug will cause memory corrupted (the largest range is from 0x3ffc0000 ~ 0x3ffc8000),
some strange error will happen, like IllegalInstruction, LoadProhibited and .etc.
List of changes:
* Corner case exceptions are properly handled to ensure release of memory occupied by security infrastructure
* fixed erroneous cleanup of security instance by protocomm_console
List of changes:
* Version endpoint now sends the set version string instead of verifying the incoming version string. This simplifies fetching version info from the provisioning application.
* esp_prov script updated to expect version string as response.
This will be useful if a webserver is already running and the application
does not want protocomm to start a new instance.

* http_sess_set_*_override APIs are now the only ones available to set custom recv/send/pending functions
* Fixed side effects to using http_sess_set/get_context inside URI handlers
Changes:
- renamed `httpd_free_sess_ctx_fn_t` to `httpd_free_ctx_fn_t`
- added a `httpd_handle_t` argument to `httpd_send_func_t` and `httpd_recv_func_t`
- internal function `httpd_sess_get()` is no longer static, as it's used in other
files besides httpd_sess.c
Bug fixes:
- removed a trailing semicolon from `HTTPD_DEFAULT_CONFIG()`
- fixed issue with failed `select()`, now it automatically closes invalid sockets
instead of shutting down the entire server
New features:
- `httpd_resp_send()` and `httpd_resp_send_chunk()` now accept -1 as length to use
`strlen()` internally
- added `httpd_sess_set_ctx()` to accompany `httpd_sess_get_ctx()`
- added a "transport context" to the session structure (next to user context)
- added `httpd_sess_{get,set}_transport_ctx()` to work with this transport context
- added "global user context" and "global transport context" stored in the server
config (and then the handle); supports a user-provided free_fn
- added a "pending func" to e.g. check for data in the transport layer receive
buffer
- added functions `httpd_set_sess_{send,recv,pending}_override()` that target
a session by ID (i.e. not using a request object)
- added `httpd_set_pending_override()`
- added a "open_fn" and "close_fn" - functions called when creating and closing
a session. These may be used to set up transport layer encryption or some other
session-wide feature

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).
Bootloader used to calculate the number of cache pages assuming that
load address was aligned, while in reality load address for DROM and
IROM was offset by 0x20 bytes from the start of 64kB page. This
caused the bootloader to map one less page if the size of the image
was 0x4..0x1c less than a multiple of 64kB.

1. Change bus reset to handle interrupted READ sequences.
2. Slow down I2C to 100khz during reset
3. If a SLAVE device was in a read operation when the bus was interrupted, the SLAVE device is controlling SDA.The only bit during the 9 clock cycles of a byte READ the MASTER(ESP32) is guaranteed control over, is during the ACK bit period.
If the SLAVE is sending a stream of ZERO bytes, it will only release SDA during the ACK bit period. The master(ESP32) cannot generate a STOP unless SDA is HIGH. So, this reset code synchronizes the bit stream with, Either, the ACK bit, Or a 1 bit.
I am stealing this delay coding from @jeremyherbert #2493 pr.
2. Change Bus Reset to handle interrupted READ sequences.
The current code does not handle interrupted READ cycles.
If a SLAVE device was in a read operation when the bus was interrupted, the SLAVE device is controlling SDA.
The only bit during the 9 clock cycles of a byte READ the MASTER(ESP32) is guaranteed control over, is during the ACK bit period.
If the SLAVE is sending a stream of ZERO bytes, it will only release SDA during the ACK bit period. The master(ESP32) cannot generate a STOP unless SDA is HIGH.
So, this reset code synchronizes the bit stream with, Either, the ACK bit, Or a 1 bit.

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.
It has been observed that, in case of underflow (data unavailability) in
I2S transmission, previously filled up tx descriptors continue to get
transmitted on line, causing noise in case of audio use case.
This change adds optional `tx_desc_auto_clear` field during I2S driver intialization
than can zero initialize tx descriptor in case of underflow situation in
interrupt handler itself.

A workaround to reset BBPLL configuration after light sleep. Fixes the
issue that Wi-Fi can not receive packets after waking up from light
sleep.
Ref. https://github.com/espressif/esp-idf/issues/2711
On enabling flash encryption, OTA fails with magic byte error in the second chunk
if the http data is split into two or more chunks and first chunk is less than 16.
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
Hostname option has been removed from dhcp discover since IDFv3.2.
But it remains in dhcp request due to which ESP32 can not get IPv4 address
from some APs. Re-add hostname option to dhcp discover to solve this issue.
When ethernet enable again after disable it before, phy init will report timeout.
The cause of this problem is that the enabling of emac clock is too late, and should be placed before phy init.
Introduced in 9c23b8e5 and 4f87a62f. To get higher speed, menuconfig
options are added to put ISR and other functions into the IRAM. The
interrupt flag ESP_INTR_FLAG_IRAM is also mistakenly set when the ISR is
put into the IRAM. However callbacks, which are wrote by the user, are
called in the master and slave ISR. The user may not be aware of that
these callbacks are not disabled during flash operations. Any cache miss
during flash operation will cause panic.
Essentially IRAM functions and intrrupt flag ESP_INTR_FLAG_IRAM are
different, the latter means not disabling the ISR during flash
operations. New bus_config flag intr_flags is offered to help set the
interrupt attribute, including priority level, SHARED, IRAM (not
disabled during flash operations). It introduced a small BREAK to
IDFv3.1 (but the same as IDFv3.0) that the user has to manually set IRAM
flag now (therefore he's aware of the IRAM thing) to void the ISR being
disabled during flash operations.

4. add APIs esp_mesh_disconnect() and esp_mesh_connect().
5. disconnect from parent/router when the DSSS channel in received beacon is different from the home channel.
6. remove nvs task to release 3k bytes memory.
Having two different spinlocks is problematic due to possibly
different order in which the locks will be taken. Changing the order
would require significant restructuring of kernel code which is
undesirable.
An additional place where taking xTickCountMutex was needed was in
vApplicationSleep function. Not taking xTickCountMutex resulted in
other CPU sometimes possibly advancing tick count while light sleep
entry/exit was happening. Taking xTickCountMutex in addition to
xTaskQueueMutex has shown a problem that in different code paths,
these two spinlocks could be taken in different order, leading to
(unlikely, but possible) deadlocks.
When light sleep is finished on one CPU, it is possible that the other
CPU will enter light sleep again very soon, before interrupts on the
first CPU get a chance to run. To avoid such situation, set a flag
for the other CPU to skip light sleep attempt.
Tickless idle/light sleep procedure had a bug in single core mode.
Consider the flow of events:
1. Idle task runs and calls vApplicationIdleHook
2. This calls esp_vApplicationIdleHook, which calls esp_pm_impl_idle_hook, and pm lock for RTOS on the current core is released.
3. Then esp_vApplicationIdleHook calls esp_pm_impl_waiti, which checks that s_entered_light_sleep[core_id]==false and goes into waiti state.
4. Some interrupt happens, calls esp_pm_impl_isr_hook, which takes pm lock for RTOS. PM state goes back to CPU_FREQ_MAX.
5. Once the interrupt is over, vApplicationIdleHook returns, and Idle task continues to run, finally reaching the call to vApplicationSleep.
6. vApplicationSleep does not enter light sleep, because esp_pm_impl_isr_hook has already changed PM state from IDLE to CPU_FREQ_MAX.
This didn’t happen in dual core mode, because waiti state of one CPU was interrupted by CCOMPARE update interrupt from the other CPU, in which case PM lock for FreeRTOS was not taken.
Fix by inverting the meaning of the flag (for convenience) and only setting it to true when vApplicationSleep actually fails to enter light sleep.

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.

Problem Decribe
The problem happenned when do wps with a mikrotik router
1. router always want to do connect with 32 without EAP-WSC step
2. after 4 way timeour, 32 crash
Root Cause
The reason why can not start EAP-WSC step is router's check method is RSN > WPA > WPS, when it found there include RSN and WPS in assoc, it will choice do 4 way rather than WPS
The reason of second problem is 32's EAPOL start timer didn't stop and send EAPOL start to a null pointer
Soultion
1. remove RSN and WPA ie when do WPS step
2. check mac address's pointer before send EAPOL start

Routine `spi_flash_cache2phys` sometimes return incorrect value,

In some cases, when data was just written into UART FIFO, transmitter
state could be still zero while the FIFO did contain some data.
This resulted in uart_tx_wait_idle occasionally returning before all
the data was sent out.
Fix by checking both UART transmitter state and TX FIFO count.
ROM definition of `abort` was removed in 9240bbb. The old definition
resulted in a panic due to a jump to a null pointer (abort member in
ROM stub table was zero). The new definition triggers a debug
exception if JTAG is connected, or goes into an infinite loop to be
reset by the WDT.
Some logging done in soc component may happen before logging via
stdout is possible. Use _EARLY version of log calls to make sure that

not impact the application.

Added a new API esp_tls_set_global_ca_store(esp_tls_cfg_t *cfg) which creates a global_cacert which can be used by multiple connections by setting the use_global_ca_store variable to true in their respective structure of esp_tls_cfg_t. Also changed the cacert in the structure of esp_tls_t to a pointer.
* BLE and softAP provisioning examples added along with tests.
* An application specific example added for demonstrating custom provisioning scheme.
* tools/esp_prov/esp_prov.py can be used as a provisioning client for SoftAP, BLE and CLI based transports.

* This manages secure sessions and provides framework for multiple transports.
* The application can use protocomm layer directly to have application specific extensions for provisioning (or non-provisioning) use cases.
* Following features are available for provisioning :
* Security - Security0 (no security), Security1 (curve25519 key exchange + AES-CTR encryption)
* Proof-of-possession support for Security1
* Protocomm requires specific protocol buffer modules for compilation which can be generated from the `.proto` files in the `proto` directory using make.

tcp_transport component used public header files such as 'transport.h', etc. which are too generic and might collide with user or user libraries headers
This change closes#2417
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.
Problem Description
The reporduce steps are as follows:
1. put more than one same ssid AP in the environment;
2. set the STA mac address in one of the APs blacklist, and make sure the AP is closest to STA;
3. set the scan method in station config as all channel scan;
4. try to connect the AP which set STA in blacklist
Phenmenon
STA fail to connect after send auth or assoc with a wrong status code, but no disconnect event report and can not connect the next one in the envrionment
Root Cause
Because there are some same ssid APs in the evnrionment, when do all channel scan, it will collect all the matched AP in rc list, because rc list is not empty, so it would send disconnect event, however, we didn't do other step such as connect to other one

_rtc_data_{start,end} can now describe data placed into RTC_FAST
segment, if CONFIG_ESP32_RTCDATA_IN_FAST_MEM is enabled.
Use new _rtc_slow_length symbol instead.
When CONFIG_ESP32_RTCDATA_IN_FAST_MEM is enabled, RTC data is placed
into RTC_FAST memory region, viewed from the data bus. However the
bootloader was missing a check that this region should not be
overwritten after deep sleep, which caused .rtc.bss segment to loose
its contents after wakeup.
fix the bug following:
1. after disable bluetooth controller, wifi cannot TX/RX any packets.
2. when software coexist working, there's a little ratio cause wifi task watchdog timeout
3. when software coexist working, there's a little ratio cause bluetooth cannot receive anything.
feature:
1. add libbtdm_app.a git commit local and remote checking
Known issues:
1. there's still a bug occurs with a very very low ratio cause bluetooth
cannot receive anything. The reproduce interval may great than 3days ~ 1week via
7x24 hours heavy testing.
Previously, esp-touch only supports multicast packets which are
transmitted from cellphone. But for most dual frequency routers
whose SSIDs of 5G and 2.4G are the same, broadcast packets are
forwarded from 5G interface to 2.4G interface while multicast
packets are not. In order to make esp-touch work when cellphone
connects to 5G interface of these routers, esp-touch is improved
to support both multicast and broadcast packets. Meanwhile, new
APP which is compiled with Andriod or IOS library(>= v0.3.6.2)
must be used in this situation. Note that for some routers,
broadcast and multicast packets are forwarded from 5G interface
to 2.4G interface only when another WiFi device is connected to
2.4G interface of the router. Old APP which is compiled with
Android or IOS library(< v0.3.6.2) also works with this improvement
when cellphone connects to 2.4G interface of the router.
The Android and IOS library of new esp-touch APP is now available
on Github.

IOS: https://github.com/EspressifApp/EsptouchForIOS
Four internal APIs `esp_http_client_connect()`, `http_client_prepare_first_line()`, `esp_http_client_request_send()` and
`esp_http_client_send_post_data()` API have been added for perfoming connection establishment (sync as well as async),
preparing first line, sending request and sending post data respectively.
In `transport_ssl`, `ssl_connect_async()` API has been added for establishing asynchronous connection.

Problem Description
set some of routers as the same ssid in the same channel, when 32 in the fast scan connect mode, there may no disconnect event report in that two sceanrio:
1. set the correct password and connect, if target router didn't report 32's auth req before timeout, the state machine change to init but no disconnect event report
2. set a wrong password, if router send disassoc or deauth after run, rather than wait 4 way handshake timeout, the state machine change to init but no disconnect event report
Root Cause
Because the routers are in the same channel, all of them are matched the ssid, so all of them can be instore in the rc list wait for connect, when the first one want to connect fail at auth or receive
disassoc or deauth when password wrong, the rc list is not empty, it can not send disconnect event because rc is not empty
Solution
1. put the fail the router in the blacklist
2. Judge whether there is another router can be connect, if it has, try to connect with the next one

gen_esp_err_to_name.py includes files like
components/lwip/include/apps/esp_ping.h as "apps/esp_ping.h" because all
subdirectories of "include" are used. If "components/lwip/include/apps"
is in the path of the compiler instead of "components/lwip/include" then
include "apps/esp_ping.h" will fail. This fix allows to process lines
like:
'// gen_esp_err_to_name.py: some text "esp_ping.h" some text'
in header files for overwriting the include.
Before LwIP was moved into a submodule, sntp and esp_ping were
available as the following includes:
#include "apps/sntp/sntp.h"
#include "esp_ping.h"
This commit makes header files available at the old location, and adds
a deprecation warning for sntp.h.
Closes https://github.com/espressif/esp-idf/issues/2392
The lwip code didn't create an new mld group when netif is up,
this will lead to the server can't find the matching netif when
receiving NS(neighbor solicitation) packet
If exception support is disabled in IDF, and libstdc++ tries to throw
an exception, it will call __cxa_allocate_exception which is replaced
with abort in IDF.
We have a dramatically size reduction of the RO-section in binary when using '__throw_'-stubs in GCC5
In the case of using GCC8, we are faced with 'multiple definition' errors when using '__throw_'-stubs.
Good that we don't have the size problem due to gcc8
