7e418833 - scsi: zfcp: diagnostics buffer caching and use for exchange port data

Fri, 25 Oct 2019 16:12:44 +0000

scsi: zfcp: diagnostics buffer caching and use for exchange port dataThe FCP channel exposes two central interfaces to receive information aboutthe local FCP-Adapter/-Port: Exchange Port and Exchange Config Data. Usingthese commands can negatively impact the adapter if we allow them to besent at a very high rate.The later parts of this patchset will introduce new user-interfaces toreceive more diagnostics from the adapter. To prevent any negative impactfrom using those, this patch adds a simple caching-mechanism that willprevent a malicious/faulty userspace-application from generating anabnormal high amount of Exchange Port/Config Data traffic.Relevant diagnostic data that is received via Exchange Config/Port Data iscached in buffers associated with the corresponding adapter-struct. Eachbuffer is associated with a timestamp that signals how old the data is,and, added via a following patch in this series, lets userspace-interfacesdetermine when the data is too old and needs to be updated.Buffer-updates are made during the normal response path of thecorresponding command. With this patch only the output of the Exchange PortData command is captured.Link: https://lore.kernel.org/r/054ca020ce0a53dc0d9176428bea373898944e6a.1572018130.git.bblock@linux.ibm.comReviewed-by: Steffen Maier Signed-off-by: Benjamin Block Signed-off-by: Martin K.

9fa1db4c - s390: add a few more SPDX identifiers

Mon, 04 Dec 2017 09:39:38 +0000

s390: add a few more SPDX identifiersAdd the correct SPDX license to a few more files under arch/s390 anddrivers/s390 which have been missed to far.The SPDX identifier is a legally binding shorthand, which can be usedinstead of the full boiler plate text.Signed-off-by: Martin Schwidefsky List of files: /linux-6.15/drivers/s390/scsi/Makefile

663e0890 - [SCSI] zfcp: remove access control tables interface

Fri, 26 Apr 2013 14:13:54 +0000

[SCSI] zfcp: remove access control tables interfaceThis patch removes an interface that was used to manage access controltables within the HBA. The patch consequently removes the handlingfor conditions related to those access control tables, too.That initiator-based access control feature was only needed until theintroduction of NPIV and was withdrawn with z10 years ago.It's time to cleanup the corresponding device driver code.Signed-off-by: Martin Peschke Signed-off-by: Steffen Maier Signed-off-by: James Bottomley List of files: /linux-6.15/drivers/s390/scsi/Makefile

1daa4eb5 - [SCSI] zfcp: Move code for managing zfcp_unit devices to new file

Wed, 08 Sep 2010 12:39:52 +0000

[SCSI] zfcp: Move code for managing zfcp_unit devices to new fileMove the code for managing zfcp_unit devices to the new filezfcp_unit.c. This is in preparation for the change that zfcp_unit willonly track the LUNs configured via unit_add, other data will be movedfrom zfcp_unit to the new struct zfcp_scsi_dev.Reviewed-by: Swen Schillig Signed-off-by: Christof Schmitt Signed-off-by: James Bottomley List of files: /linux-6.15/drivers/s390/scsi/Makefile

60221920 - [SCSI] zfcp: consolidate sysfs things into one file.

Wed, 02 Jul 2008 08:56:38 +0000

[SCSI] zfcp: consolidate sysfs things into one file.zfcp was using three files to deal with sysfs representationfor adapters, ports and units. The consolidation into one fileprevents code-duplication and eases maintainability.Signed-off-by: Swen Schillig Signed-off-by: Christof Schmitt Signed-off-by: James Bottomley List of files: /linux-6.15/drivers/s390/scsi/Makefile

45633fdc - [SCSI] zfcp: Move CFDC code to new file.

Tue, 10 Jun 2008 16:20:55 +0000

[SCSI] zfcp: Move CFDC code to new file.zfcp implements a device file to allow Linux guests changing theAccess Control Tables stored in the adapter. The code for the devicefile has nothing to do with the other parts of the driver, so move itto a new file and cleanup the code while doing so.Signed-off-by: Christof Schmitt Signed-off-by: Swen Schillig Signed-off-by: James Bottomley List of files: /linux-6.15/drivers/s390/scsi/Makefile

8a36e453 - [SCSI] zfcp: enhancement of zfcp debug features

Tue, 13 Sep 2005 19:50:38 +0000

[SCSI] zfcp: enhancement of zfcp debug featuresDebug features (DBFs) els_dbf, cmd_dbf and abt_dbf were removed andsan_dbf, hba_dbf and scsi_dbf were introduced. The erp_dbf did notchange.The new traces improve debugging of problems with zfcp, scsi-stack,multipath and hardware in the SAN. san_dbf traces things like ELS andCT commands, hba_dbf saves HBA specific information of requests, andscsi_dbf saves FCP and SCSI specific information of requests. Commonto all new DBFs is that they provide a so called structured view. Thissignificantly improves readability of the traces.Signed-off-by: Andreas Herrmann Signed-off-by: James Bottomley List of files: /linux-6.15/drivers/s390/scsi/Makefile

1da177e4 - Linux-2.6.12-rc2

Sat, 16 Apr 2005 22:20:36 +0000

Linux-2.6.12-rc2Initial git repository build. I'm not bothering with the full history,even though we have it. We can create a separate "historical" gitarchive of that later if we want to, and in the meantime it's about3.2GB when imported into git - space that would just make the earlygit days unnecessarily complicated, when we don't have a lot of goodinfrastructure for it.Let it rip!
