Some APs are configured to hide the SSID, the length field of the SSID element
in the Beacon frame is set to 0. This can cause incorrect parsing of the Beacon
by the Wi-Fi MAC hardware.
Some APs send two beacon frames with different BSSID in a TBTT cycle. After
correctly parsing the beacon of the associated AP, it continue to receive the
other beacon frame, which will cause the MAC to remain in a wait RX/TXING
state, blocking the Wi-Fi go to sleep.
...and all their callers.
With the upcoming switch from sizeof(time_t)==4 to sizeof(time_t)==8,
sizeof(struct stat) is also increasing.
A few newlib functions present in ROM allocate 'struct stat' on the
stack and call _fstat_r on this structure. The implementation of
fstat is provided in ESP-IDF. This implementation will often do
memset(st, 0, sizeof(*st)), where st is 'struct stat*', before setting
some fields of this structure. If IDF is built with sizeof(st)
different from sizeof(st) which ROM was built with, this will lead
to an out-of-bounds write and a stack corruption.
This commit removes problematic ROM functions from the linker script.
Here are the functions which allocate 'struct stat':
* _isatty_r (in ROM)
* __swhatbuf_r, called by __smakebuf_r, called by __swsetup_r and
__srefill_r (in ROM)
* _fseeko_r (not in ROM)
* glob2 (not in ROM)
* _gettemp (not in ROM)
As a result, these functions are used from libc.a, and use correct
size of 'stat' structure.
