Hello,
from what I can get from the sources and gdb
sethostname(name,len) calls
_hurd_set_host_config("/etc/hostname",name,len)
then
_hurd_set_host_config gets the port of /etc, creates a port
for
hostname if neccesary, or gets the old port for
/etc/hostname.
Then __io_write is called, with as (new,name,len,0,&nwrote)
I noticed nwrote a mach_msg_type_number_t didn't change from
before io_write was called and after. Also it's this
io_write
that is finding the bad file descriptor. I haven't found the
sources for the __io_write function yet. This __io_write
finds a bad file descriptor no matter if /etc/hostname exists
or
not.
