Release Notes v7.3.1¶
The BeeGFS 7.3.1 release includes changes to the default mount options and security configuration as well as some other fixes and QoL improvements.
Before upgrading to this version, please read the section about
security improvements below carefully. If
you have not configured a
connAuthFile, services will no longer start
without configuration changes. For more background on why we make this
change, please refer to our blog post on the topic.
The client will now use the
nosuidmount option by default to prevent users from escalating privileges by using setuid binaries. This can be overridden by setting
suidas a mount option in
connAuthFileis now mandatory. Services will no longer start if
connAuthFileis not configured or connection authentication is explicitly disabled by setting the new configuration option
true. Please refer to our documentation about Authentication for more information about setting up connection authentication.
nativecache mode is no longer marked as experimental.
We have discovered an issue with the native cache mode on new kernels (Linux 5.15 in Ubuntu 22.04 and Linux 5.14 in RHEL 9), where the page cache is corrupted during read. Although on-disk data is not affected, we advise against using the native cache mode on kernels newer than 5.13 with an upatched BeeGFS 7.3.1 client. A patch is available here.
TCP and UDP receive buffer sizes can now be configured independently from the RDMA buffer size with the configuration options
connUDPRcvBufSize. The default values of
0will preserve the legacy behavior of setting the buffer size to
connRDMABufNum * connRDMABufSize. Setting the value to
-1will set the buffer size to system defaults.
Improved performance when selecting a connection from the client connection pool by reordering the connection according to availability.
Updated the client module to work with Linux 5.15 to support RHEL 9 and Ubuntu 22.04.
Removed unnecessary memory context switching in standard socket code.
Some general code cleanup.
RDMA events with event code
RDMA_CM_EVENT_TIMEWAIT_EXITwill no longer be logged by default. They will still be logged on log level
connAuthFileconfiguration to client runtime config in procfs to fix an issue where
--mountflag was not able to connect to other servers when
Fixed a bug in the RDMA buffer allocation that caused the client module to crash during OPA and RoCE device initialization on newer kernels (RHEL >8.5, Ubuntu 22.04).
--accessflag in the
--createfilewill no longer ignore special bits for setuid, setgid and sticky.
Known Issues and Limitations¶
The Metadata daemon does not work reliably on RHEL/CentOS 8 and SLES 15.1 and 15.2 due to a problem in the versions of glibc. The problem was fixed in RHEL/CentOS 8.1 and SLES 15.3.
The client module might hang if the IBV device(s) used are taken offline during operation.
The client module does not compile on SLES 15.2 with Mellanox OFED 5.2
