"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nsmack: /smack/doi: accept previously used values\n\nWriting to /smack/doi a value that has ever been\nwritten there in the past disables networking for\nnon-ambient labels.\nE.g.\n\n # cat /smack/doi\n 3\n # netlabelctl -p cipso list\n Configured CIPSO mappings (1)\n DOI value : 3\n mapping type : PASS_THROUGH\n # netlabelctl -p map list\n Configured NetLabel domain mappings (3)\n domain: \"_\" (IPv4)\n protocol: UNLABELED\n domain: DEFAULT (IPv4)\n protocol: CIPSO, DOI = 3\n domain: DEFAULT (IPv6)\n protocol: UNLABELED\n\n # cat /smack/ambient\n _\n # cat /proc/$$/attr/smack/current\n _\n # ping -c1 10.1.95.12\n 64 bytes from 10.1.95.12: icmp_seq=1 ttl=64 time=0.964 ms\n # echo foo >/proc/$$/attr/smack/current\n # ping -c1 10.1.95.12\n 64 bytes from 10.1.95.12: icmp_seq=1 ttl=64 time=0.956 ms\n unknown option 86\n\n # echo 4 >/smack/doi\n # echo 3 >/smack/doi\n!> [ 214.050395] smk_cipso_doi:691 cipso add rc = -17\n # echo 3 >/smack/doi\n!> [ 249.402261] smk_cipso_doi:678 remove rc = -2\n!> [ 249.402261] smk_cipso_doi:691 cipso add rc = -17\n\n # ping -c1 10.1.95.12\n!!> ping: 10.1.95.12: Address family for hostname not supported\n\n # echo _ >/proc/$$/attr/smack/current\n # ping -c1 10.1.95.12\n 64 bytes from 10.1.95.12: icmp_seq=1 ttl=64 time=0.617 ms\n\nThis happens because Smack keeps decommissioned DOIs,\nfails to re-add them, and consequently refuses to add\nthe “default” domain map:\n\n # netlabelctl -p cipso list\n Configured CIPSO mappings (2)\n DOI value : 3\n mapping type : PASS_THROUGH\n DOI value : 4\n mapping type : PASS_THROUGH\n # netlabelctl -p map list\n Configured NetLabel domain mappings (2)\n domain: \"_\" (IPv4)\n protocol: UNLABELED\n!> (no ipv4 map for default domain here)\n domain: DEFAULT (IPv6)\n protocol: UNLABELED\n\nFix by clearing decommissioned DOI definitions and\nserializing concurrent DOI updates with a new lock.\n\nAlso:\n- allow /smack/doi to live unconfigured, since\n adding a map (netlbl_cfg_cipsov4_map_add) may fail.\n CIPSO_V4_DOI_UNKNOWN(0) indicates the unconfigured DOI\n- add new DOI before removing the old default map,\n so the old map remains if the add fails\n\n(2008-02-04, Casey Schaufler)"
