MRT_ADD_MEMBERSHIP failed; Errno(105): No buffer space available #30
Comments
Maybe you have too small limit for maximal membership? |
|
I confirm that changing this parameter corrects the issue. Thanks for the hint - I had no idea this setting existed! I would suggest adding a note to the documentation about this or printing a suitable "check igmp_max_memberships" log entry to explain the likely cause. |

- Update from 0.2.1 to 0.3
- Update of rootfile not required
- Changelog
2021-01-04 18:40:01 +0100 Pali Rohár <pali.rohar@gmail.com>
* Release version 0.3
2020-09-05 13:52:50 +0200 Pali Rohár <pali.rohar@gmail.com>
* Remove duplicate code in mcgroup.c file
Existing functionality is provided by k_join and k_leave functions.
2020-09-05 13:07:38 +0200 Pali Rohár <pali.rohar@gmail.com>
* Fix initialization and deinitialization of mrouter socket
Ensure that uninitialized socket is invalid (-1) and not stdin (0).
2020-09-05 13:07:00 +0200 Pali Rohár <pali.rohar@gmail.com>
* Use main mrouter socket also for sending join/leave messages to upstream router
There is no need to open additional UDP socket which is used just for calling
IP_ADD_MEMBERSHIP/IP_DROP_MEMBERSHIP setsockopt. Main mrouter socket is can
be used for these operations too.
2020-05-20 09:59:11 +0200 Uglymotha <uglymotha@wizdom.nu>
* Free BSD Compilation Patch
On FreeBSD compilation failed due to missing includes in os-freebsd.h.
This was causing errors about undefined structs and types in missing includes.
Also defines __BSD_VISIBLE due to FreeBSD not providing u_int, u_long etc
in a default _POSIX_C_SOURCE environment.
Fixes: pali/igmpproxy#68
2020-05-08 22:54:06 +0200 Pali Rohár <pali.rohar@gmail.com>
* Remove MAX_MC_VIFS macro
Its value is same as MAXVIFS, so use MAXVIFS instead.
2020-03-06 11:51:21 +0100 Pali Rohár <pali.rohar@gmail.com>
* Improve downstream host tracking for quickleave mode
Use bit based per multicast route hash table for tracking downstream hosts.
For hasing function is used 32bit MurmurHash3 with pseudorandom seed and
size of hash table can be configured via a new "hashtablesize" token in
config file. Default size of hash table is 32 bytes, so it can store
approximatelly 128 hosts which is half of /24 subnet. For home networks
this should be sane default value.
Fixes: pali/igmpproxy#57
2020-02-26 20:27:08 +0100 Pali Rohár <pali.rohar@gmail.com>
* Show error message when IP_ADD_MEMBERSHIP fails with errno ENOBUFS

My configuration file is:
