46ac6441 - net/smc: introduce loopback-ism for SMC intra-OS shortcut

Sun, 28 Apr 2024 06:07:29 +0000

net/smc: introduce loopback-ism for SMC intra-OS shortcutThis introduces a kind of Emulated-ISM device named loopback-ism forSMCv2.1. The loopback-ism device is currently exclusive for SMC usage,and aims to provide an SMC shortcut for sockets within the same kernel,leading to improved intra-OS traffic performance. Configuration of thisfeature is managed through the config SMC_LO.Signed-off-by: Wen Gu Reviewed-by: Gerd Bayer Reviewed-by: Wenjia Zhang Reviewed-and-tested-by: Jan Karcher Signed-off-by: Paolo Abeni List of files: /linux-6.15/net/smc/Kconfig

a72178cf - net/smc: Fix dependency of SMC on ISM

Fri, 06 Oct 2023 12:58:47 +0000

net/smc: Fix dependency of SMC on ISMWhen the SMC protocol is built into the kernel proper while ISM isconfigured to be built as module, linking the kernel fails due tounresolved dependencies out of net/smc/smc_ism.o toism_get_smcd_ops, ism_register_client, and ism_unregister_clientas 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 thedependencies that are actually inverted. With this you cannot build akernel 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-s390architectures that do not have (nor need) an ISM driver.Fixes: 89e7d2ba61b7 ("net/ism: Add new API for client registration")Reported-by: Randy Dunlap Closes: https://lore.kernel.org/linux-next/d53b5b50-d894-4df8-8969-fd39e63440ae@infradead.org/Co-developed-by: Wenjia Zhang Signed-off-by: Wenjia Zhang Signed-off-by: Gerd Bayer Reviewed-by: Simon Horman Tested-by: Simon Horman # build-testedAcked-by: Randy Dunlap Tested-by: Randy Dunlap # build-testedLink: https://lore.kernel.org/r/20231006125847.1517840-1-gbayer@linux.ibm.comSigned-off-by: Paolo Abeni List of files: /linux-6.15/net/smc/Kconfig

a7f7f624 - treewide: replace '---help---' in Kconfig files with 'help'

Sat, 13 Jun 2020 16:50:22 +0000

treewide: replace '---help---' in Kconfig files with 'help'Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over'---help---'"), the number of '---help---' has been graduallydecreasing, 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 thefollowing commend: $ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/'Signed-off-by: Masahiro Yamada List of files: /linux-6.15/net/smc/Kconfig

smc: establish new socket family* 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.
