This issue impacts the QUIC listeners. It is the same as the one fixed by this commit: BUG/MINOR: quic: repeat packet parsing to deal with fragmented CRYPTO As chrome, ngtcp2 client decided to fragment its CRYPTO frames but in a much more agressive way. This could be fixed with a list local to qc_parse_pkt_frms() to please chrome thanks to the commit above. But this is not sufficient for ngtcp2 which often splits its ClientHello message into more than 10 fragments with very small ones. This leads the packet parser to interrupt the CRYPTO frames parsing due to the ncbuf gap size limit. To fix this, this patch approximatively proceeds the same way but with an ebtree to reorder the CRYPTO by their offsets. These frames are directly inserted into a local ebtree. Then this ebtree is reused to provide the reordered CRYPTO data to the underlying ncbuf (non contiguous buffer). This way there are very few less chances for the ncbufs used to store CRYPTO data to reach a too much fragmented state. Must be backported as far as 2.6.
