0ed37ac5 - mptcp: depends on IPV6 but not as a module

Wed, 21 Oct 2020 10:51:53 +0000

mptcp: depends on IPV6 but not as a moduleLike TCP, MPTCP cannot be compiled as a module. Obviously, MPTCP IPv6'support also depends on CONFIG_IPV6. But not all functions from IPv6code are exported.To simplify the code and reduce modifications outside MPTCP, it wasdecided from the beginning to support MPTCP with IPv6 only ifCONFIG_IPV6 was built inlined. That's also why CONFIG_MPTCP_IPV6 wascreated. More modifications are needed to support CONFIG_IPV6=m.Even if it was not explicit, until recently, we were forcing CONFIG_IPV6to be built-in because we had "select IPV6" in Kconfig. Now that we have"depends on IPV6", we have to explicitly set "IPV6=y" to forceCONFIG_IPV6 not to be built as a module.In other words, we can now only have CONFIG_MPTCP_IPV6=y ifCONFIG_IPV6=y.Note that the new dependency might hide the fact IPv6 is not supportedin MPTCP even if we have CONFIG_IPV6=m. But selecting IPV6 like we didbefore was forcing it to be built-in while it was maybe not what theuser wants.Reported-by: Geert Uytterhoeven Fixes: 010b430d5df5 ("mptcp: MPTCP_IPV6 should depend on IPV6 instead of selecting it")Signed-off-by: Matthieu Baerts Link: https://lore.kernel.org/r/20201021105154.628257-1-matthieu.baerts@tessares.netSigned-off-by: Jakub Kicinski List of files: /linux-6.15/net/mptcp/Kconfig

357b41ca - mptcp: select CRYPTO

Sat, 15 Feb 2020 14:45:56 +0000

mptcp: select CRYPTOWithout this modification and if CRYPTO is not selected, we have thiswarning: WARNING: unmet direct dependencies detected for CRYPTO_LIB_SHA256 Depends on [n]: CRYPTO [=n] Selected by [y]: - MPTCP [=y] && NET [=y] && INET [=y]MPTCP selects CRYPTO_LIB_SHA256 which seems to depend on CRYPTO. CRYPTOis now selected to avoid this issue.Even though the config system prints that warning, it looks likesha256.c is compiled and linked even without CONFIG_CRYPTO. Since MPTCPwill end up needing CONFIG_CRYPTO anyway in future commits -- currentlyin preparation for net-next -- we propose to add it now to fix thewarning.The dependency in the config system comes from the fact thatCRYPTO_LIB_SHA256 is defined in "lib/crypto/Kconfig" which is sourcedfrom "crypto/Kconfig" only if CRYPTO is selected.Fixes: 65492c5a6ab5 (mptcp: move from sha1 (v0) to sha256 (v1))Signed-off-by: Matthieu Baerts Signed-off-by: David S.

389b8fb3 - mptcp: MPTCP_HMAC_TEST should depend on MPTCP

Wed, 29 Jan 2020 18:02:24 +0000

mptcp: MPTCP_HMAC_TEST should depend on MPTCPAs the MPTCP HMAC test is integrated into the MPTCP code, it can bebuilt only when MPTCP is enabled. Hence when MPTCP is disabled, askingthe user if the test code should be enabled is futile.Wrap the whole block of MPTCP-specific config options inside a check forMPTCP. While at it, drop the "default n" for MPTCP_HMAC_TEST, as thatis the default anyway.Fixes: 65492c5a6ab5df50 ("mptcp: move from sha1 (v0) to sha256 (v1)")Signed-off-by: Geert Uytterhoeven Reviewed-by: Mat Martineau Signed-off-by: David S.

f870fa0b - mptcp: Add MPTCP socket stubs

Wed, 22 Jan 2020 00:56:15 +0000

mptcp: Add MPTCP socket stubsImplements the infrastructure for MPTCP sockets.MPTCP sockets open one in-kernel TCP socket per subflow. These subflowsockets are only managed by the MPTCP socket that owns them and are notvisible from userspace. This commit allows a userspace program to openan MPTCP socket with: sock = socket(AF_INET, SOCK_STREAM, IPPROTO_MPTCP);The resulting socket is simply a wrapper around a single regular TCPsocket, without any of the MPTCP protocol implemented over the wire.Co-developed-by: Florian Westphal Signed-off-by: Florian Westphal Co-developed-by: Peter Krystad Signed-off-by: Peter Krystad Co-developed-by: Matthieu Baerts Signed-off-by: Matthieu Baerts Co-developed-by: Paolo Abeni Signed-off-by: Paolo Abeni Signed-off-by: Mat Martineau Signed-off-by: Christoph Paasch Signed-off-by: David S.
