Matthieu Baerts (NGI0) 06c62385be mptcp: pm: avoid computing add_addr size twice ... mptcp_add_addr_len helper was called twice: in mptcp_pm_add_addr_signal, then just after in mptcp_established_options_add_addr. Both to check the remaining space. The second call is not needed: if there is not enough space, mptcp_pm_add_addr_signal will return false, and the caller, mptcp_established_options_add_addr, will do the same without re-checking the size again. Instead, mptcp_pm_add_addr_signal can directly set the size. Note that the returned size can be negative when other suboptions are dropped, e.g. to send an echo ADD_ADDR with a v4 address, and no port. While at it: - move mptcp_add_addr_len to pm.c, as it is now only used from there - use 'int' in mptcp_add_addr_len for the size, instead of having a mix - use a bool for 'ret' in mptcp_pm_add_addr_signal Reviewed-by: Mat Martineau <martineau@kernel.org> Signed-off-by: Matthieu Baerts (NGI0) <matttbe@kernel.org> Link: https://patch.msgid.link/20260605-net-next-mptcp-add-addr6-port-ts-v2-3-758e7ca73f4d@kernel.org Signed-off-by: Jakub Kicinski <kuba@kernel.org>		2026-06-11 15:33:37 -07:00
