Title
espintcp: use sk_msg_free_partial to fix partial send
Summary
In the Linux kernel, the following vulnerability has been resolved: espintcp: use sk_msg_free_partial to fix partial send sk_msg_free_partial() ensures consistency of the skmsg at every iteration, without having to manually handle uncharges and offsets. This simplifies the code, and fixes some bugs in skmsg accounting when we don't send the full contents.
