net/smc: Fix dependency of SMC on ISM

2023-10-10T09:51:41+00:00

When the SMC protocol is built into the kernel proper while ISM is configured to be built as module, linking the kernel fails due to unresolved dependencies out of net/smc/smc_ism.o to ism_get_smcd_ops, ism_register_client, and ism_unregister_client as reported via the linux-next test automation (see link). This however is a bug introduced a while ago. Correct the dependency list in ISM's and SMC's Kconfig to reflect the dependencies that are actually inverted. With this you cannot build a kernel with CONFIG_SMC=y and CONFIG_ISM=m. Either ISM needs to be 'y', too - or a 'n'. That way, SMC can still be configured on non-s390 architectures that do not have (nor need) an ISM driver.

treewide: replace '---help---' in Kconfig files with 'help'

2020-06-13T16:57:21+00:00

Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over '---help---'"), the number of '---help---' has been gradually decreasing, but there are still more than 2400 instances. This commit finishes the conversion. While I touched the lines, I also fixed the indentation. There are a variety of indentation styles found. a) 4 spaces + '---help---' b) 7 spaces + '---help---' c) 8 spaces + '---help---' d) 1 space + 1 tab + '---help---' e) 1 tab + '---help---' (correct indentation) f) 1 tab + 1 space + '---help---' g) 1 tab + 2 spaces + '---help---' In order to convert all of them to 1 tab + 'help', I ran the following commend: $ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/' Signed-off-by: Masahiro Yamada

net/smc: remove Kconfig warning

2017-07-29T18:22:58+00:00

Now separate memory regions are created and registered for separate RMBs. The unsafe_global_rkey of the protection domain is no longer used. Thus the exposing memory warning can be removed. Signed-off-by: Ursula Braun Signed-off-by: David S. Miller

net/smc: Add warning about remote memory exposure

2017-05-16T18:49:43+00:00

The driver explicitly bypasses APIs to register all memory once a connection is made, and thus allows remote access to memory. Signed-off-by: Christoph Hellwig Signed-off-by: Leon Romanovsky Acked-by: Ursula Braun Signed-off-by: David S. Miller

smc: establish new socket family

2017-01-09T21:07:38+00:00

* enable smc module loading and unloading * register new socket family * basic smc socket creation and deletion * use backing TCP socket to run CLC (Connection Layer Control) handshake of SMC protocol * Setup for infiniband traffic is implemented in follow-on patches. For now fallback to TCP socket is always used. Signed-off-by: Ursula Braun Reviewed-by: Utz Bacher Signed-off-by: David S. Miller
