  "message": "libibverbs: Set vmr-\u003eaccess in ibv_cmd_reg_mr_ex()\n\n[ Upstream commit 45c66ed5603b7a11491214fb3dc4a1d0b1626277 ]\n\nibv_cmd_reg_mr_ex() did not record the MR\u0027s access flags in vmr-\u003eaccess,\nunlike ibv_cmd_reg_mr().  ibv_dereg_mr() decides whether to re-enable fork\ntracking from verbs_get_mr(mr)-\u003eaccess:\n\n    if (... \u0026\u0026 !(access \u0026 IBV_ACCESS_ON_DEMAND))\n            ibv_dofork_range(addr, length);\n\nWith vmr-\u003eaccess left zero, an on-demand (ODP) MR registered through\nibv_reg_mr_ex() / ibv_cmd_reg_mr_ex() reads access \u003d\u003d 0 at dereg, so\nibv_dofork_range() runs even though registration skipped the matching\nibv_dontfork_range() for ODP (need_fork \u003d !(ON_DEMAND || FD)).  The\nunbalanced dofork corrupts the fork-range accounting when ibv_fork_init()\nis enabled.\n\nSet vmr-\u003eaccess \u003d mr_init_attr-\u003eaccess on the success path, mirroring\nibv_cmd_reg_mr(), so the dereg fork decision is correct.  (The write-ABI\nfallback path already goes through ibv_cmd_reg_mr(), which sets it.)\n\nFixes: ca61708a8838 (\"verbs: Add ibv_cmd_reg_mr_ex() to be used by drivers\")\nSigned-off-by: Yishai Hadas \u003cyishaih@nvidia.com\u003e\nSigned-off-by: Jiri Pirko \u003cjiri@nvidia.com\u003e\nCo-Authored-By: Claude Opus 4.8 \u003cnoreply@anthropic.com\u003e\nSigned-off-by: Nicolas Morey \u003cnmorey@suse.com\u003e\n",
