Ignoramus here, too (even possibly ignoramus squared :), but I wanted
to show of the new plaything I stumbled upon. I put GNUTLS_E_PULL_ERROR
into https://sources.debian.org/ yields (among many) this hit, where
that seems to happen:

  https://sources.debian.org/src/gnutls28/3.7.4-2/lib/system/ktls.c/?hl=391#L391

So the meaning seems to be "we received some funny error in recvmsg
which we didin't bother to cach explicitly (the latter being EAGAIN,
EINVAL, EMSGSIZE, EBADMSG). Having a look at which other errors
recvmsg documents, anything is possible, a more harmless being, e.g.
out of memory.
