Hi! This is v2 of a proposed patch set for fixing file ID collisions with 9pfs.
Patch 1 to 3 are identical to the previous version. New in this v2 is patch 4 which introduces variable length suffixes for inode mapping instead of fixed length prefixes. Also: patch 4 disables file ID persistency at compile time by default for now, since I am yet unresolved about details of that persistency. Christian Schoenebeck (4): 9p: mitigates most QID path collisions 9P: trivial cleanup of QID path collision mitigation 9p: persistency of QID path beyond reboots / suspensions 9p: use variable length suffixes for inode mapping fsdev/9p-marshal.h | 6 +- hw/9pfs/9p.c | 1145 ++++++++++++++++++++++++++++++++++++++++++++++++-- hw/9pfs/9p.h | 167 ++++++++ hw/9pfs/trace-events | 14 +- 4 files changed, 1296 insertions(+), 36 deletions(-) -- 2.11.0
