Subject: [PATCH] mptcpize: force MPTCP usage for IPPROTO_IP, too (#159)
|
||||||
|
|
||||||
|
The current ignores calls alike:
|
||||||
|
|
||||||
|
socket(AF_INET, SOCK_STREAM, IPPROTO_IP)
|
||||||
|
|
||||||
|
We should hijack them, too.

Subject: [PATCH] mptcpize: use explicit file copy instead of rename() (#161)
|
||||||
|
|
||||||
|
The mentioned syscall fails if the involved files belong to
|
||||||
|
different fs, which is pretty much expected in the relevant
|
||||||
|
scenario (tmp file, in tmpfs, and unit file usually under the
|
||||||
|
root partition)
|
||||||
|
|
||||||
|
Instead use sendfile() to explicitly copy all the contents. Note
|
||||||
|
that we need to close and re-open the unit file, as sendfile()
|
||||||
|
expect a O_WRITE fd as the target.
