[lwip-devel] [bug #23835] Bug in PPP.(Using sys_msleep() in pppOverSerialOpen())

[Frédéric Bernon]

Follow-up Comment #1, bug #23835 (project lwip):

sys_arch.txt says about "sys_arch_timeouts" : "...This function is called by
the lwIP timeout scheduler and must not return a NULL value." 

So, even if the function which call directly or indirectly
"sys_arch_timeouts" is not created by "sys_thread_new", you have a provide a
valid return to this call. In fact, "sys_thread_new" is just here to provide a
system-independant call for lwIP core.

If the "sys_arch_timeouts" implementation in your port returns NULL for
thread which are not created by "sys_thread_new" - which is the bug to my
point of view - you should fix it, or call pppOverSerialOpen from a "lwip"
thread.
