Closes https://github.com/espressif/esp-idf/issues/8451
This commit brings two esp-lwip fixes to IDF:
1) Add configuration to disable DHCP client identification
2195f7416f
This config could be used to disable option 61 in DHCP packets, so that
clients will be identified by their chaddr only.
(This is the lwip upstream original behaviour)
2) Fix server_idx increasing to DNS_MAX_SERVERS and trigger the LWIP_ASSERT
5a567d52f7
When lwip doesn't have DNS server and resolve a domain address, the server_idx
will increase to DNS_MAX_SERVERS, which will trigger the LWIP_ASSERT and make device crash.
Closes https://github.com/espressif/esp-idf/issues/6878
If silent assert configuration is enabled, LWIP asserts are now 'silent' also.
Also updates KConfig to note that LWIP asserts are also disabled when asserts
are disabled globally (this was already the behaviour, but the config item
suggested otherwise.)
Progress towards https://github.com/espressif/esp-idf/issues/5873
This caused some unsigned int prints out to be printed as singed integer which made the logs unreadable, for example sequence numbers in TCP packet headers
LWIP_HOOK_FILENAME is used in IDF to define standard and default hooks for IDF port in LWIP.
Added ESP_IDF_LWIP_HOOK_FILENAME to customize additional hooks in lwip
Closes https://github.com/espressif/esp-idf/issues/6261
Include external ram section in the linker template to process it
through linker script generation mechanism. This enables redirection of .bss section to external memory using linker fragments
libnet80211, libpp, libbt, liblwip: Redirect .bss through fragments
Added lwIP hooks which could be optionally overwritten in the
application code. These three options are provided in Kconfig:
* NONE: No hook support
* DEFAULT: Default implementation is provided. If IDF doesn't
have a specific hook implementation, an empty stub is provided, which
could be overwritten by strong implementation in application code.
* CUSTOM: Hooks are declared only to be implemented in application code.
