[lwip-devel] [bug #23408] Deadlock on sys_mbox_post sys_mbox_fetch

[Vadim G Melihow]

Follow-up Comment #8, bug #23408 (project lwip):

Comment #5 - a result of my negligence.  ;-)
Comment #6 -  much correctly.

i.e.
between
 sys_sem_signal(mbox->mutex); 
and
 sys_arch_sem_wait(mbox->mail, 0);
from function sys_arch_mbox_fetch, possibly multiple execution of function
sys_arch_mbox_post which can lock mbox->mail

Thats all. I think.
