Hello, I tried another script for the semantic patch language out. This source code analysis approach points out that the implementation of the function “tcp_time_wait” contains also a call of the function “kmemdup”. https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/net/ipv4/tcp_minisocks.c?id=1c0cc5f1ae5ee5a6913704c0d75a6e99604ee30a#n306 https://elixir.bootlin.com/linux/v5.4-rc2/source/net/ipv4/tcp_minisocks.c#L306 * Do you find the usage of the macro call “BUG_ON” still appropriate at this place? https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/scripts/checkpatch.pl?id=1c0cc5f1ae5ee5a6913704c0d75a6e99604ee30a#n4080 * Is there a need to adjust the error handling here? Regards, Markus
