* Patched longjmp to be context-switch safe
longjmp modifies the windowbase and windowstart
registers, which isn't safe if a context switch
occurs during the modification. After a context
switch, windowstart and windowbase will be
different, leading to a wrongly set windowstart
bit due to longjmp writing it based on the
windowbase before the context switch. This
corrupts the registers at the next window
overflow reaching that wrongly set bit.
The solution is to disable interrupts during
this code. It is only 6 instructions long,
the impact shouldn't be significant.
The fix is implemented as a wrapper which
replaces the original first instructions of
longjmp which are buggy. Then, it jumps back
to execute the rest of the original longjmp
function.
Added a comparably reliable test to the
test apps.
Since dd849ffc, _rodata_start label has been moved to a different
linker output section from where the TLS templates (.tdata, .tbss)
are located. Since link-time addresses of thread-local variables are
calculated relative to the section start address, this resulted in
incorrect calculation of THREADPTR/$tp registers.
Fix by introducing new linker label, _flash_rodata_start, which points
to the .flash.rodata output section where TLS variables are located,
and use it when calculating THREADPTR/$tp.
Also remove the hardcoded rodata section alignment for Xtensa targets.
Alignment of rodata can be affected by the user application, which is
the issue dd849ffc was fixing. To accommodate any possible alignment,
save it in a linker label (_flash_rodata_align) and then use when
calculating THREADPTR. Note that this is not required on RISC-V, since
this target doesn't use TPOFF.
It is now possible to have any alignment restriction on rodata in the user
applicaiton. It will not affect the first section which must be aligned
on a 16-byte bound.
Closes https://github.com/espressif/esp-idf/issues/6719
rodata dummy section has now the same alignment as flash text section,
and at least the same size. For these reasons, the cache will map
correctly the following rodata section.
Theory is that the large alignments in this test component are triggering linker
bug (to be fixed in next toolchain update). This component is already tested
in a dedicated config, so it doesn't need to be included in this config.
1. Fix mesh deinit blocking issue
2. Fix root has no eb for deauth frames during the networking
3. Add esp_mesh_send_block_time to set blocking time of esp_mesh_send
4. Forward Mgmt frames with skipping CCMP headers to fix parsing issues in Application for ESP32C3
1. Removed the interrupt lock operation during controller enable/disable/reset, to avoid trigger interrupt watchdog time-out due to use of mutex/semaphore in coex_st_set
2: Update libbtbb.a for ESP32-C3 to fix the Rx performance issue for CODED PHY, especially in coexistence scenario
