Re: [B.A.T.M.A.N.] batman-adv and 11n speed

Elektra, You're correct. I disabled batman-adv, the speed will still return to 11g after a second IBSS board is up. that has something to do with rate-discovery-under-IBSS for mac80211/ath9k I think. thanks, xxiao --- On Mon, 7/6/09, elektra <onelektra(a)gmx.net> wrote: > From: elektra <onelektra(a)gmx.net> > Subject: Re: [B.A.T.M.A.N.] batman-adv and 11n speed > To: austinxxh-ath9k(a)yahoo.com, "The list for a Better Approach To Mobile Ad-hoc Networking" <b.a.t.m.a.n(a)lists.open-mesh.net> > Date: Monday, July 6, 2009, 2:43 PM > Hi xxiao - > > I guess your problem is not related to batman-adv - I would > plea not > guilty unless proven otherwise.

[B.A.T.M.A.N.] batman-adv and 11n speed
by xxiao 06 Jul '09

06 Jul '09

Hi, I'm using Openwrt/compat-wireless-2009-06-25 on a AR7161 board. I'm using ath9k trying to get 11n speed for batman-adv working. All code is from openwrt trunk. >From the debugfs of mac80211/ath9k, I can see under IBSS mode, the rcstat reports speed up to 300mbps. I have batman-adv enabled. However after a second board with the same software booted up, both boards' rcstat output showed a speed of 11g only, an immediate drop from 11n to 11g. It's like the second batman-adv somehow forced a 11g speed after it "talked" to the first batman-adv board. Any help is appreciated! xxiao Before the second batman-adv is booted up: root@OpenWrt:/# cat /mnt/ath9k/phy0/rcstat Rate Success Retries XRetries PER 1.0: 0 0 0 0 2.0: 0 0 0 0 5.5: 0 0 0 0 11.0: 0 0 0 0 6.0: 0 0 0 0 9.0: 0 0 0 0 12.0: 0 0 0 0 18.0: 0 0 0 0 24.0: 0 0 0 0 36.0: 0 0 0 0 48.0: 0 0 0 0 54.0: 0 0 0 0 6.5: 0 0 0 0 13.0: 0 0 0 0 19.5: 0 0 0 0 26.0: 0 0 0 0 39.0: 0 0 0 0 52.0: 0 0 0 0 58.5: 0 0 0 0 65.0: 0 0 0 0 13.0: 0 0 0 0 26.0: 0 0 0 0 39.0: 0 0 0 0 52.0: 0 0 0 0 78.0: 0 0 0 0 104.0: 0 0 0 0 117.0: 0 0 0 0 130.0: 0 0 0 0 13.5: 0 0 0 0 27.5: 0 0 0 0 40.5: 0 0 0 0 54.0: 0 0 0 0 81.5: 0 0 0 0 108.0: 0 0 0 0 121.5: 0 0 0 0 135.0: 0 0 0 0 150.0: 0 0 0 0 27.0: 0 0 0 0 54.0: 0 0 0 0 81.0: 0 0 0 0 108.0: 0 0 0 0 162.0: 0 0 0 0 216.0: 0 0 0 0 243.0: 0 0 0 0 270.0: 0 0 0 0 300.0: 0 0 0 0 after the second batman-adv is up: root@OpenWrt:/# cat /mnt/ath9k/phy0/rcstat Rate Success Retries XRetries PER 1.0: 0 0 0 0 2.0: 0 0 0 0 5.5: 0 0 0 0 11.0: 0 0 0 0 6.0: 0 0 0 0 9.0: 0 0 0 0 12.0: 0 0 0 0 18.0: 0 0 0 0 24.0: 0 0 0 0 36.0: 0 0 0 0 48.0: 0 0 0 0 54.0: 0 0 0 0 On both boards I have this: root@OpenWrt:/# iwconfig lo no wireless extensions. eth0 no wireless extensions. eth1 no wireless extensions. br-lan no wireless extensions. wlan0 IEEE 802.11abgn ESSID:"xyz" Mode:Ad-Hoc Frequency:2.432 GHz Cell: 92:46:0A:A3:8B:39 Tx-Power=27 dBm Retry long limit:7 RTS thr:off Fragment thr:off Encryption key:off Power Management:off Link Quality:0 Signal level:0 Noise level:0 Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:0 Missed beacon:0 bat0 no wireless extensions.

[B.A.T.M.A.N.] originators says yes, batping says no
by Jacob Marble 04 Jul '09

04 Jul '09

I have three nodes running OpenWrt r16484 (SVN) and batman-advanced r1298. All nodes show each other in originators. batping gets host unreachable for all relationships, and the host unreachable messages come very quickly, maybe 1000/second. Here is a log sample, log_level 4. log_level 11 doesn't show anything. The setup I'm using worked fine with r1176. Using ahdemo.

[B.A.T.M.A.N.] [PATCH] json output from vis server would fail with incomplete writes
by jonathan mzengeza 02 Jul '09

02 Jul '09

Hi Jonathan here I am attending a code sprint here at CSIR in South Africa. We are using B.A.T.M.A.N as a mesh networking software. We ran into a bug which occurred with web browser whereby the data written back through the socket was not complete thereby causing an error with our program. The fix works by making sure that all the data that is to be sent in the send_buffer is sent. It checks the value of ret until it equals the size of the data to be sent. -- Index: vis.c =================================================================== --- vis.c (revision 1336) +++ vis.c (working copy) @@ -580,8 +580,18 @@ } else { send_buffer = current->json_buffer; } + + ret = write( thread_data->socket, send_buffer, strlen( send_buffer )); - ret = write( thread_data->socket, send_buffer, strlen( send_buffer ) ); + while(ret != strlen( send_buffer )) { + send_buffer += ret; + + if ( fsync(thread_data->socket) != 0 ) { + ret = write(thread_data->socket, send_buffer, strlen( send_buffer )); + } + + } + if( ret != strlen( send_buffer ) || (thread_data->format == json) ) { pthread_mutex_lock( &current->mutex );
