commit a84db616737cda5dfc6e8590a29523dc08090f60

    gprs: Add assertion for msg != NULL to bssgp_msgb_alloc (Coverity)
    Currently out-of-memory is not handled by bssgp_msgb_alloc, leading
    to SEGV failures if msgb_alloc_headroom returns NULL.
    This commit adds an OSMO_ASSERT to catch this case, which improves
    the situation only slightly. But bssgp_msgb_alloc is used in many
    places without checking the return value, so just adding a
    conditional early NULL return would not fix the issue either.

commit d154f8bda2e379a8a0e1c3712a9af6a9d97b7b97
Author: Jacob Erlbeck <jerlbeck at>

    msgb: Check the return value of msgb_alloc (Coverity)
    In some places, the return value of msgb_alloc/msgb_alloc_headroom
    is not checked before it is dereferenced.
    This commit adds NULL checks to return with -ENOMEM from the calling
    functions if the alloc function has failed.
    Fixes: Coverity CID 1249692, 1293376
