results after patching dhcp6.c

Hello.
Thank You very much for Your quick response and sorry for my delayed
one. Will try to be faster next time.
So I applied the patch You provided against dhcp6.c, recompiled dhcpcd
and took a look at systemd's journal. As main difference there were four
additional lines
d6_open 0
d6_open 1
d6_open 2
d6_open 3
at the end, a more verbose sdiff is attached. Also attached the log from
an i686 laptop where the connection works flawlessly as mentioned in my
first post.
There's one more thing imo worth mentioning: if CPPFLAGS comprises
-D_FORTIFY_SOURCE=2, which is e. g. default in Arch Linux's ABS, there
are three warnings
dhcp.c: In function 'dhcp_handleifudp':
dhcp.c:2637:2: warning: ignoring return value of 'read',
declared with attribute warn_unused_result [-Wunused-result]
(void)read(state->udp_fd, buffer, sizeof(buffer));
^
dhcp.c: In function 'dhcp_handleudp':
dhcp.c:2622:2: warning: ignoring return value of 'read',
declared with attribute warn_unused_result [-Wunused-result]
(void)read(ctx->udp_fd, buffer, sizeof(buffer));
^
compat/arc4random.c: In function 'arc4_stir':
compat/arc4random.c:112:3: warning: ignoring return value of
'read', declared with attribute warn_unused_result [-Wunused-result]
(void)read(fd, rdat.rnd, sizeof(rdat.rnd));
^
These warnings also appear if dhcpcd is recompiled using ABS on my i686
/ x86_64 devices, where the problem we're discussing doesn't exist, though.

P. Mattern
