[Olsr-dev] OLSR issues

[Bluse]

Hi all,

Since a couple of month I observe some log messages from olsrd in our Freifunk mesh, that I just want to share, although the actual routing works fine.
Just in case there is something interesting for the development about this issue. (There were a couple of email in Jan.2016 that went in the same direction but their was no solution yet.)

So here my observations


(A) regular olsrd start on nodes with a single wlan interface (UBIQUITY Bullet M5 & Nanosation M5):
=>no dmesg output related to olsrd, routing works properly

(B)regular olsrd start on nodes with 2x wlan interfaces (2,4GHz AP mode & 5 GHz adhoc mode) 

(B.1) TPLink 4300 (MIPS):

=>olsrd is running and routing works properly, dmesg shows:

do_page_fault(): sending SIGSEGV to olsrd for invalid write access to 00000000
epc = 7763d4d0 in libc.so[7760e000+9d000]
ra  = 00425c90 in olsrd[400000+4c000]


(B.2) TPLink 4900 (POWERPC):

=>olsrd is running and routing works properly, dmesg shows:

olsrd[19632]: unhandled signal 11 at 00000000 nip b78555b4 lr b78554b4 code 30001


MANUAL START OF OLSRD with debug level 6:

olsrd -d 6 -file /var/etc/olsrd.conf -nofork

-> just a single line of output:
*** olsr.org - 0.9.0.3-git_10f0c39-hash_31e08ea6498c03a8f02694181402cf0d (2016-01-27 11:30:48 on TPLink4900.lan) ***

-no further debug output at all (should I use a different command ?)


after CRTL + C:

^C
