01c7a597 - fs: dlm: remove deprecated code parts

Mon, 06 Mar 2023 20:48:11 +0000

fs: dlm: remove deprecated code partsThis patch removes code parts which was declared deprecated bycommit 6b0afc0cc3e9 ("fs: dlm: don't use deprecated timeout features bydefault"). This contains the following dlm functionality:- start a cancel of a dlm request did not complete after certain timeout: The current way how dlm cancellation works and interfering with other dlm requests triggered by the user can end in an overlapping and returning in -EBUSY. The most user don't handle this case and are unaware that DLM can return such errno in such situation. Due the timeout the user are mostly unaware when this happens.- start a netlink warning messages for user space if dlm requests did not complete after certain timeout: This feature was never being built in the only known dlm user space side. As we are to remove the timeout cancellation feature we can directly remove this feature as well.There might be the possibility to bring the timeout cancellation featureback. However the current way of handling the -EBUSY case which is onlya software limitation and not a hardware limitation should be changed.We minimize the current code base in DLM cancellation feature to not haveto deal with those existing features while solving the DLM cancellationfeature in general.UAPI define DLM_LSFL_TIMEWARN is commented as deprecated and reservedvalue. We should avoid at first to give it a new meaning but letpossible users still compile by keeping this define. In far future wecan give this flag a new meaning. The same for the DLM_LKF_TIMEOUT lockrequest flag.Signed-off-by: Alexander Aring Signed-off-by: David Teigland List of files: /linux-6.15/fs/dlm/Kconfig

81eeb82f - fs: dlm: add deprecation Kconfig and warnings for timeouts

Wed, 22 Jun 2022 18:45:22 +0000

fs: dlm: add deprecation Kconfig and warnings for timeoutsThis patch adds a CONFIG_DLM_DEPRECATED_API Kconfig optionthat must be enabled to use two timeout-related featuresthat we intend to remove in kernel v6.2. Warnings areprinted if either is enabled and used. Neither has everbeen used as far as we know.. The DLM_LSFL_TIMEWARN lockspace creation flag will be removed, along with the associated configfs entry for setting the timeout. Setting the flag and configfs file would cause dlm to track how long locks were waiting for reply messages. After a timeout, a kernel message would be logged, and a netlink message would be sent to userspace. Recently, midcomms messages have been added that produce much better logging about actual problems with messages. No use has ever been found for the netlink messages.. The userspace libdlm API has allowed the DLM_LKF_TIMEOUT flag with a timeout value to be set in lock requests. The lock request would be cancelled after the timeout.Signed-off-by: Alexander Aring Signed-off-by: David Teigland List of files: /linux-6.15/fs/dlm/Kconfig

a47666eb - fs: dlm: make connection hash lockless

Thu, 27 Aug 2020 19:02:49 +0000

fs: dlm: make connection hash locklessThere are some problems with the connections_lock. During myexperiements I saw sometimes circular dependencies with sock_lock.The reason here might be code parts which runs nodeid2con() beforeor after sock_lock is acquired.Another issue are missing locks in for_conn() iteration. Maybe thisworks fine because for_conn() is running in a context whereconnection_hash cannot be manipulated by others anymore.However this patch changes the connection_hash to be protected bysleepable rcu. The hotpath function __find_con() is implementedlockless as it is only a reader of connection_hash and this hopefullyfixes the circular locking dependencies. The iteration for_conn() willstill call some sleepable functionality, that's why we use sleepable rcuin this case.This patch removes the kmemcache functionality as I think I need tomake some free() functionality via call_rcu(). However allocation timeisn't here an issue. The dlm_allow_con will not be protected by a lockanymore as I think it's enough to just set and flush workqueuesafterwards.Signed-off-by: Alexander Aring Signed-off-by: David Teigland List of files: /linux-6.15/fs/dlm/Kconfig

[DLM] Consolidate transport protocolsThis patch consolidates the TCP & SCTP protocols for the DLM into a single fileand makes it switchable at run-time (well, at least before the DLM actuallystarts up!)For RHEL5 this patch requires Neil Horman's patch that expands the in-kernelsocket API but that has already been twice ACKed so it should be OK.The patch adds a new lowcomms.c file that replaces the existing lowcomms-sctp.c& lowcomms-tcp.c files.Signed-off-By: Patrick Caulfield Signed-off-by: Steven Whitehouse List of files: /linux-6.15/fs/dlm/Kconfig
