For maybe devices, +multipath needs to get the WWIDs of all the other block devices, to see +if they match the maybe device wwid. If one of those devices doesn't +have uid_attribute set in its udev database, multipath will check the +environment for it, and it will find that variable set to the WWID +of the maybe device that this uevent is for. This means that all +devices with no WWID will end up appearing to have the same WWID as +the maybe device, causing multipath to incorrectly claim it. + +Signed-off-by: Benjamin Marzinski +--- + libmultipath/discovery.c | 2 +- + libmultipath/structs.h | 1 + + multipath/main.c | 2 ++ + 3 files changed, 4 insertions(+), 1 deletion(-) + +diff --git a/libmultipath/discovery.c b/libmultipath/discovery.c +index f593a7bf..a592a54e 100644 +--- a/libmultipath/discovery.c ++++ b/libmultipath/discovery.c +@@ -2032,7 +2032,7 @@ get_udev_uid(struct path * pp, char *uid_attribute, struct udev_device *udev) + const char *value; + + value = udev_device_get_property_value(udev, uid_attribute); +- if (!value || strlen(value) == 0) ++ if ((!value || strlen(value) == 0) && pp->can_use_env_uid) + value = getenv(uid_attribute); + if (value && strlen(value)) { + len = strlcpy(pp->wwid, value, WWID_SIZE); +diff --git a/libmultipath/structs.h b/libmultipath/structs.h +index 0867b91d..4b308561 100644 +--- a/libmultipath/structs.h ++++ b/libmultipath/structs.h +@@ -360,6 +360,7 @@ struct path { + int fast_io_fail; + unsigned int dev_loss; + int eh_deadline; ++ bool can_use_env_uid; + /* configlet pointers */ + vector hwe; + struct gen_path generic_path; +diff --git a/multipath/main.c b/multipath/main.c +index 41d01c7e..e056c51c 100644 +--- a/multipath/main.c ++++ b/multipath/main.c +@@ -653,6 +653,8 @@ check_path_valid(const char *name, struct config *conf, bool is_uevent) + pp = alloc_path(); + if (!pp) + return RTVL_FAIL; ++ if (is_uevent) ++ pp->can_use_env_uid = true; + + r = is_path_valid(name, conf, pp, is_uevent); + if (r <= PATH_IS_ERROR || r >= PATH_MAX_VALID_RESULT) diff --git a/SPECS/device-mapper-multipath.spec b/SPECS/device-mapper-multipath.spec index 37fb28a..2c8e86f 100644 --- a/SPECS/device-mapper-multipath.spec +++ b/SPECS/device-mapper-multipath.spec @@ -1,6 +1,6 @@ Name: device-mapper-multipath Version: 0.8.7 -Release: 11%{?dist} +Release: 20%{?dist} Summary: Tools to manage multipath devices using device-mapper License: GPLv2 URL: http://christophe.varoqui.free.fr/ @@ -70,6 +70,30 @@ Patch0057: 0057-updated-HPE-MSA-builtin-config.patch Patch0058: 0058-libmultipath-unset-detect_checker-for-clariion-Unity.patch Patch0059: 0059-multipathd-Add-missing-ctype-include.patch Patch0060: 0060-multipathd-replace-libreadline-with-libedit.patch +Patch0061: 0061-multipath-fix-systemd-timers-in-the-initramfs.patch +Patch0062: 0062-multipathd-factor-out-the-code-to-flush-a-map-with-n.patch +Patch0063: 0063-libmultipath-return-success-if-we-raced-to-remove-a-.patch +Patch0064: 0064-multipathd-Handle-losing-all-path-in-update_map.patch +Patch0065: 0065-multipathd-ignore-duplicated-multipathd-command-keys.patch +Patch0066: 0066-multipath-tools-use-run-instead-of-dev-shm.patch +Patch0067: 0067-kpartx-hold-device-open-until-partitions-have-been-c.patch +Patch0068: 0068-libmultipath-cleanup-remove_feature.patch +Patch0069: 0069-libmultipath-cleanup-add_feature.patch +Patch0070: 0070-multipath-tests-tests-for-adding-and-removing-featur.patch +Patch0071: 0071-libmultipath-fix-queue_mode-feature-handling.patch +Patch0072: 0072-multipath-tests-tests-for-reconcile_features_with_qu.patch +Patch0073: 0073-libmultipath-prepare-proto_id-for-use-by-non-scsi-de.patch +Patch0074: 0074-libmultipath-get-nvme-path-transport-protocol.patch +Patch0075: 0075-libmultipath-enforce-queue_mode-bio-for-nmve-tcp-pat.patch +Patch0076: 0076-multipath.conf-5-remove-io-affinity-information.patch +Patch0077: 0077-libmultipath-don-t-leak-memory-on-invalid-strings.patch +Patch0078: 0078-libmutipath-validate-the-argument-count-of-config-st.patch +Patch0079: 0079-libmultipath-use-select_reload_action-in-select_acti.patch +Patch0080: 0080-libmultipath-select-resize-action-even-if-reload-is-.patch +Patch0081: 0081-libmultipath-cleanup-ACT_CREATE-code-in-select_actio.patch +Patch0082: 0082-libmultipath-keep-renames-from-stopping-other-multip.patch +Patch0083: 0083-multipath.rules-fix-smart-bug-with-failed-valid-path.patch +Patch0084: 0084-libmultipath-limit-paths-that-can-get-wwid-from-envi.patch # runtime @@ -161,7 +185,6 @@ cp %{SOURCE1} . %build %define _sbindir /usr/sbin %define _libdir /usr/%{_lib} -%define _udevdir /usr/lib/udev %define _libmpathdir %{_libdir}/multipath %define _pkgconfdir %{_libdir}/pkgconfig %make_build LIB=%{_lib} @@ -175,7 +198,8 @@ cp %{SOURCE1} . rcdir=%{_initrddir} \ unitdir=%{_unitdir} \ includedir=%{_includedir} \ -
