2018-10-12mgcp: Avoid initing output without enabling osmuxPau Espin Pedrol1-4/+4
Otherwise we end up in a weird state where we have timers set up but osmux is still flagged as not enabled. Change-Id: I15c3a1a6bdf2566b03d1d543d8d15e4117a53622

2018-09-17mgcp_osmux: Use define to calculate rtp_ssrc_winlenPau Espin Pedrol1-2/+2
Since that define is already used to allocate size of osmux_cid_bitmap, let's use it here too instead of hardcoding its value. Change-Id: I768ca1b510bf44508ae064dc31620e739260470b
2018-09-17mgcp: Fix (again) osmux_cid_bitmap static array size calculationPau Espin Pedrol1-2/+2
A previous commit merged today fixed array size boundary (multiple of 8 bits), but removed a required +1 which should be kept on top, because OSMUX_CID_MAX specified the maximum number used by a CID, that is (0,OSMUX_CID_MAX), and as a result we require OSMUX_CID_MAX+1 slots.

2018-09-17mgcp: Fix osmux_cid_bitmap static array size calculationPau Espin Pedrol1-1/+1
Right now it's not a big issue since OSMUX_CID_MAX is 255, so 255+1 is 256 which fits array boundaries correctly (multiple of 8). However, if for example OSMUC_CID_MAX was modified to be 12, 12+1/8 = 1, so we'd have an undesired memory access when accessing last 4 CIDs. Change-Id: I5908ee44404686e68d61f255b7014af39c8f5703

2018-08-28Fix heap-use-after-free due to OML link destructionPau Espin Pedrol4-2/+31
Back-port from osmo-bsc.git 9862bcb5cdb9ece0acfdfb7c81e00c05fcd33ad3. ipaccess_drop_oml was being called inside an osmo_fd cb context, were -EBADF must be returned if the structure holding the osmo_fd is freed. In the middle of the path (see OS#3495 for path tree) it goes through a signal dispatch, so it's impossible to make sure we return some value to the osmo_fd cb. As a result, it is required to defer dropping the OML Link from current code path and do it through a timer.

2018-07-24git-version-gen: Don't check for .git directoryDaniel Willmann1-2/+2
This check is not in all our repos that use git-version-gen. Indeed it seems to be a leftover of openbsc where I think it wanted to ensure being called in the openbsc subfolder or something? libosmocore e.g. doesn't have it. In any case .git being a directory is not always true (if using git worktree) so remove this check. Change-Id: Ibc8c0d8e74bb03bfe87d6f8b9ef6e74c0c889d0f

2018-07-04nat: Add VTY cmd paging-bss-forward to nat nodePau Espin Pedrol3-0/+28
This command controls forward/drop of BSS paging messages from MSC to all BSCs connected to BSC-NAT. In situations in which MS don't generally roam from one BSC to another under the BSC-NAT, it may be beneficial (bandwidth wise) to drop these global paging commands, which are usually issued by the MSC if the location of the MS isn't known and LAC paging has failed.
