WebSVN: http://websvn.samba.org/cgi-bin/viewcvs.cgi?view=rev&root=samba&rev=24765 Log: added a RAW-HOLD-OPLOCK test. This is a manual test, meant to be used to test the interaction of oplocks with local filesystem or NFS access. You start it, then manually access the 4 files via another mechanism (such as a shell) and see what oplock breaks you get Modified: branches/SAMBA_4_0/source/torture/raw/oplock.c branches/SAMBA_4_0/source/torture/raw/raw.c Changeset: Modified: branches/SAMBA_4_0/source/torture/raw/oplock.c =================================================================== --- branches/SAMBA_4_0/source/torture/raw/oplock.c 2007-08-29 04:06:09 UTC (rev 24764) +++ branches/SAMBA_4_0/source/torture/raw/oplock.c 2007-08-29 04:33:26 UTC (rev 24765) @@ -1388,3 +1388,112 @@ talloc_free(mem_ctx); return ret; } + + +static struct hold_oplock_info { + const char *fname; + bool close_on_break; + uint32_t share_access; + uint16_t fnum; +} hold_info[] = { + { BASEDIR "\\notshared_close", True, + NTCREATEX_SHARE_ACCESS_NONE, }, + { BASEDIR "\\notshared_noclose", False, + NTCREATEX_SHARE_ACCESS_NONE, }, + { BASEDIR "\\shared_close", True, + NTCREATEX_SHARE_ACCESS_READ|NTCREATEX_SHARE_ACCESS_WRITE|NTCREATEX_SHARE_ACCESS_DELETE, }, + { BASEDIR "\\shared_noclose", False, + NTCREATEX_SHARE_ACCESS_READ|NTCREATEX_SHARE_ACCESS_WRITE|NTCREATEX_SHARE_ACCESS_DELETE, }, +}; + +static BOOL oplock_handler_hold(struct smbcli_transport *transport, uint16_t tid, + uint16_t fnum, uint8_t level, void *private) +{ + struct smbcli_tree *tree = private; + struct hold_oplock_info *info; + int i; + + for (i=0;i<ARRAY_SIZE(hold_info);i++) { + if (hold_info[i].fnum == fnum) break; + } + + if (i == ARRAY_SIZE(hold_info)) { + printf("oplock break for unknown fnum %u\n", fnum); + return False; + } + + info = &hold_info[i]; + + if (info->close_on_break) { + printf("oplock break on %s - closing\n", + info->fname); + oplock_handler_close(transport, tid, fnum, level, private); + return True; + } + + printf("oplock break on %s - acking break\n", info->fname); + + return smbcli_oplock_ack(tree, fnum, OPLOCK_BREAK_TO_NONE); +} + + +/* + used for manual testing of oplocks - especially interaction with + other filesystems (such as NFS and local access) +*/ +BOOL torture_hold_oplock(struct torture_context *torture, + struct smbcli_state *cli) +{ + struct event_context *ev = cli->transport->socket->event.ctx; + int i; + + printf("Setting up open files with oplocks in %s\n", BASEDIR); + + if (!torture_setup_dir(cli, BASEDIR)) { + return False; + } + + smbcli_oplock_handler(cli->transport, oplock_handler_hold, cli->tree); + + /* setup the files */ + for (i=0;i<ARRAY_SIZE(hold_info);i++) { + union smb_open io; + NTSTATUS status; + + io.generic.level = RAW_OPEN_NTCREATEX; + io.ntcreatex.in.root_fid = 0; + io.ntcreatex.in.access_mask = SEC_RIGHTS_FILE_ALL; + io.ntcreatex.in.alloc_size = 0; + io.ntcreatex.in.file_attr = FILE_ATTRIBUTE_NORMAL; + io.ntcreatex.in.share_access = hold_info[i].share_access; + io.ntcreatex.in.open_disposition = NTCREATEX_DISP_OPEN_IF; + io.ntcreatex.in.create_options = 0; + io.ntcreatex.in.impersonation = NTCREATEX_IMPERSONATION_ANONYMOUS; + io.ntcreatex.in.security_flags = 0; + io.ntcreatex.in.fname = hold_info[i].fname; + io.ntcreatex.in.flags = NTCREATEX_FLAGS_EXTENDED | + NTCREATEX_FLAGS_REQUEST_OPLOCK | + NTCREATEX_FLAGS_REQUEST_BATCH_OPLOCK; + printf("opening %s\n", hold_info[i].fname); + + status = smb_raw_open(cli->tree, cli, &io); + if (!NT_STATUS_IS_OK(status)) { + printf("Failed to open %s - %s\n", + hold_info[i].fname, nt_errstr(status)); + return False; + } + + if (io.ntcreatex.out.oplock_level != BATCH_OPLOCK_RETURN) { + printf("Oplock not granted for %s - expected %d but got %d\n", + hold_info[i].fname, BATCH_OPLOCK_RETURN, + io.ntcreatex.out.oplock_level); + return False; + } + hold_info[i].fnum = io.ntcreatex.out.file.fnum; + } + + printf("Waiting for oplock events\n"); + event_loop_wait(ev); + + return True; +} Modified: branches/SAMBA_4_0/source/torture/raw/raw.c =================================================================== --- branches/SAMBA_4_0/source/torture/raw/raw.c 2007-08-29 04:06:09 UTC (rev 24764) +++ branches/SAMBA_4_0/source/torture/raw/raw.c 2007-08-29 04:33:26 UTC (rev 24765) @@ -44,6 +44,7 @@ torture_suite_add_1smb_test(suite, "OPEN", torture_raw_open); torture_suite_add_1smb_test(suite, "MKDIR", torture_raw_mkdir); torture_suite_add_suite(suite, torture_raw_oplock(suite)); + torture_suite_add_1smb_test(suite, "HOLD-OPLOCK", torture_hold_oplock); torture_suite_add_2smb_test(suite, "NOTIFY", torture_raw_notify); torture_suite_add_1smb_test(suite, "MUX", torture_raw_mux); torture_suite_add_1smb_test(suite, "IOCTL", torture_raw_ioctl);
