Functions within the OS must never set the errno value. fs_fdopen() was setting the errno value. Now, after some parameter changes, it reports errors via a negated errno integer return value as do most all other internal OS functions.
It's better to have a default working for many cases.
Usually DNS servers are not optimized for embedded clients.
Users can fine tune for their environment anyway.
1. Move pthread-specific data files from sched/pthread/ to libs/libc/pthread.
2. Remove pthread-specific data functions from syscalls.
3. Implement tls_alloc() and tls_free() with system calls.
4. Reimplement pthread_key_create() and pthread_key_free() using tls_alloc() and tls_free().
5. Reimplement pthread_set_specific() and pthread_get_specicif() using tls_set_value() and tls_get_value()
- Remove per-thread errno from the TCB structure (pterrno)
- Remove get_errno() and set_errno() as functions. The macros are still available as stubs and will be needed in the future if we need to access the errno from a different address environment (KERNEL mode).
- Add errno value to the tls_info_s structure definitions
- Move sched/errno to libs/libc/errno. Replace old TCB access to the errno with TLS access to the errno.
Move the logic to get TLS information from an inline function to a normal function. For the unaligned case, it is probably too large to be inlined.
Also fixes some minor things from review of previous commits.
CONFIG_TLS_ALIGNED will select the (legacy) aligned stack implementation of TLS. If CONFIG_TLS_ALIGNED is not defined, then the new, implementation of TLS using an unaligned stack will be enabled.
The new OS interface, sched_get_stackinfo() combines two pthread-specific interfaces into a single generic interface. The existing pthread_get_stackaddr_np() and pthread_get_stacksize_np() are moved from sched/pthread to libs/libc/pthread.
There are two motivations for this change: First, it reduces the number of system calls. Secondly, it adds a common hook that is going to used for a future implementation of TLS.
This change is needed to be able to fix the warnings on the audio core
and includes the propagation of the fix in the audio.
