https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D213611 Bug ID: 213611 Summary: ports-mgmt/pkg: 1.9.1 pkgdb locking doesn't work on NFS Product: Ports & Packages Version: Latest Hardware: Any OS: Any Status: New Severity: Affects Some People Priority: --- Component: Individual Port(s) Assignee: pkg@FreeBSD.org Reporter: mwennrich@gmail.com Assignee: pkg@FreeBSD.org Flags: maintainer-feedback?(pkg@FreeBSD.org) pkg info fails with following error, if /var/db/pkg is on NFS: pkg: sqlite error while executing iterator in file pkgdb_iterator.c:1033: database is locked ktrace: 61912 pkg CALL setgroups(0x1,0x802780abc) 61912 pkg RET setgroups 0 61912 pkg CALL setegid(0xfffe) 61912 pkg RET setegid 0 61912 pkg CALL setgid(0xfffe) 61912 pkg RET setgid 0 61912 pkg CALL seteuid(0xfffe) 61912 pkg RET seteuid 0 61912 pkg CALL setuid(0xfffe) 61912 pkg RET setuid 0 61912 pkg CALL=20 mkdir(0x80301c2e8,0x1ff<S_IRUSR|S_IWUSR|S_IXUSR|S_IRGRP|S_IWGRP|S_IXGRP|S_I= ROTH|S_IWOTH|S_IXOTH>) 61912 pkg NAMI "/var/db/pkg/local.sqlite.lock" 61912 pkg RET mkdir -1 errno 13 Permission denied =3D=3D> privileges get dropped and only afterwards mkdir /var/db/pkg/local.sqlite.lock is tried, which has to fail as user "nobody". Verified with "chmod 777 /var/db/pkg/" drwxr-xr-x 2 nobody nobody 4096 Oct 19 12:50 local.sqlite.lock >From src/info.c: 322 323 drop_privileges(); 324 if (pkgdb_obtain_lock(db, PKGDB_LOCK_READONLY) !=3D EPKG_OK) { 325 pkgdb_close(db); Probably wrong order of drop_privileges and pkgdb_obtain_lock? This happens only on NFS because of this in src/pkgdb.c: 1026 /* 1027 * Fall back on unix-dotfile locking strategy if on a network filesys= tem 1028 */ (...) 1034 sqlite3_vfs_register(sqlite3_vfs_find("unix-dotfile"), 1); (Our quick workaround was to comment out the whole "fall back on unix-dotfi= le on NFS" part. Probably not the best solution ...) --=20 You are receiving this mail because: You are the assignee for the bug.=
