Ehen using pblk with 0 sized metadata both ppa list and meta list points to the same memory since pblk_dma_meta_size() returns 0 in that case. This patch fix that issue by ensuring that pblk_dma_meta_size() always returns space equal to sizeof(struct pblk_sec_meta) and thus ppa list and meta list points to different memory address. Even that in that case drive does not really care about meta_list pointer, this is the easiest way to fix that issue without introducing changes in many places in the code just for 0 sized metadata case. The same approach needs to be also done for pblk_get_sec_meta() since we also cannot point to the same memory address in meta buffer when we are using it for pblk recovery process Reported-by: Hans Holmberg <hans.holmberg@cnexlabs.com> Tested-by: Hans Holmberg <hans.holmberg@cnexlabs.com> Signed-off-by: Igor Konopko <igor.j.konopko@intel.com> Signed-off-by: Matias Bjørling <mb@lightnvm.io> Signed-off-by: Jens Axboe <axboe@kernel.dk> |
