From: Martin Wilck <mwilck@xxxxxxxx> Hi Christophe, hi Ben, This is part III of a larger patch series for multpath-tools I've been preparing. It contains fixes for a customer issue where the same alias was set for several maps with different WWIDs in the WWIDs file. Note that this does *not* break the scenario Ben described in his response to v1 of the part of the series. Details in the commit message of patch 41/42. This part based on the previously submitted part II (which is completely unchanged from the v1 submission and not re-posted). The full series will also be available here: https://github.com/mwilck/multipath-tools/tree/ups/submit-2008 This part is tagged "submit-200812-3". Changes v1 -> v2, as suggested by Ben Marzinski: * 40/42 "libmultipath: refuse creating map with duplicate alias" - dropped, as this breaks valid scenarios * 40/42 "libmultipath: free_multipath(): remove mpp references" - new patch added, required to avoid segfaults; inserted here to preserve numbering * 41/42 "libmultipath: refuse reloading an existing map with different WWID" - unchanged, but not reviewed yet. Commit message improved. NOTE: part VI and VII of the the series contain patches related to the topic of this part, improving the handling of inconsistent alias settings further: 80/80 "libmultipath: select_action(): don't drop map if alias clashes" 84/84 "libmultipath: add consistency check for alias settings" Regards, Martin Martin Wilck (3): libmultipath: free_multipath(): remove mpp references libmultipath: refuse reloading an existing map with different WWID libmultipath: dm_addmap(): refuse creating map with empty WWID libmultipath/configure.c | 19 +++++++++++++++---- libmultipath/devmapper.c | 26 +++++++++++++++----------- libmultipath/structs.c | 15 +++++++++++++++ 3 files changed, 45 insertions(+), 15 deletions(-) -- 2.28.0 -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
