______________________________________________________________________________
An update that fixes two vulnerabilities is now available.
Description:
This update for slurm_20_02 fixes the following issues:
Security issues fixed:
o CVE-2020-27745: Fixed a potential buffer overflow from use of unpackmem
(bsc#1178890).
o CVE-2020-27746: Fixed a potential leak of the magic cookie when sent as an
argument to the xauth command (bsc#1178891).
Non-security issues fixed:
o Updated to 20.02.6. Full log and details available at: * https://
lists.schedmd.com/pipermail/slurm-announce/2020/000045.html
o Updated to 20.02.5, changes: * Fix leak of TRESRunMins when job time is
changed with --time-min * pam_slurm - explicitly initialize slurm config to
support configless mode. * scontrol - Fix exit code when creating/updating
reservations with wrong Flags. * When a GRES has a no_consume flag, report
0 for allocated. * Fix cgroup cleanup by jobacct_gather/cgroup. * When
creating reservations/jobs don't allow counts on a feature unless using an
XOR. * Improve number of boards discovery * Fix updating a reservation
NodeCnt on a zero-count reservation. * slurmrestd - provide an explicit
error messages when PSK auth fails. * cons_tres - fix job requesting single
gres per-node getting two or more nodes with less CPUs than requested
per-task. * cons_tres - fix calculation of cores when using gres and
cpus-per-task. * cons_tres - fix job not getting access to socket without
GPU or with less than --gpus-per-socket when not enough cpus available on
required socket and not using --gres-flags=enforce binding. * Fix HDF5 type
version build error. * Fix creation of CoreCnt only reservations when the
first node isn't available. * Fix wrong DBD Agent queue size in sdiag when
using accounting_storage/none. * Improve job constraints XOR option logic.
* Fix preemption of hetjobs when needed nodes not in leader component. *
Fix wrong bit_or() messing potential preemptor jobs node bitmap, causing
bad node deallocations and even allocation of nodes from other partitions.
* Fix double-deallocation of preempted non-leader hetjob components. *
slurmdbd - prevent truncation of the step nodelists over 4095. * Fix nodes
remaining in drain state state after rebooting with ASAP option. - changes
from 20.02.4:
* srun - suppress job step creation warning message when waiting on
PrologSlurmctld. * slurmrestd - fix incorrect return values in
data_list_for_each() functions. * mpi/pmix - fix issue where HetJobs could
fail to launch. * slurmrestd - set content-type header in responses. * Fix
cons_res GRES overallocation for --gres-flags=disable-binding. * Fix
cons_res incorrectly filtering cores with respect to GRES locality for
--gres-flags=disable-binding requests. * Fix regression where a dependency
on multiple jobs in a single array using underscores would only add the
first job. * slurmrestd - fix corrupted output due to incorrect use of
memcpy(). * slurmrestd - address a number of minor Coverity warnings. *
Handle retry failure when slurmstepd is communicating with srun correctly.
* Fix jobacct_gather possibly duplicate stats when _is_a_lwp error shows
up. * Fix tasks binding to GRES which are closest to the allocated CPUs. *
Fix AMD GPU ROCM 3.5 support. * Fix handling of job arrays in sacct when
querying specific steps. * slurmrestd - avoid fallback to local socket
authentication if JWT authentication is ill-formed. * slurmrestd - restrict
ability of requests to use different authentication plugins. * slurmrestd -
unlink named unix sockets before closing. * slurmrestd - fix invalid
formatting in openapi.json. * Fix batch jobs stuck in CF state on FrontEnd
mode. * Add a separate explicit error message when rejecting changes to
active node features. * cons_common/job_test - fix slurmctld SIGABRT due to
double-free. * Fix updating reservations to set the duration correctly if
updating the start time. * Fix update reservation to promiscuous mode. *
Fix override of job tasks count to max when ntasks-per-node present. * Fix
min CPUs per node not being at least CPUs per task requested. * Fix CPUs
allocated to match CPUs requested when requesting GRES and threads per core
equal to one. * Fix NodeName config parsing with Boards and without CPUs. *
Ensure SLURM_JOB_USER and SLURM_JOB_UID are set in SrunProlog/Epilog. * Fix
error messages for certain invalid salloc/sbatch/srun options. * pmi2 -
clean up sockets at step termination. * Fix 'scontrol hold' to work with
'JobName'. * sbatch - handle --uid/--gid in #SBATCH directives properly. *
Fix race condition in job termination on slurmd. * Print specific error
messages if trying to run use certain priority/multifactor factors that
cannot work without SlurmDBD. * Avoid partial GRES allocation when
--gpus-per-job is not satisfied. * Cray - Avoid referencing a variable
outside of it's correct scope when dealing with creating steps within a het
job. * slurmrestd - correctly handle larger addresses from accept(). *
Avoid freeing wrong pointer with SlurmctldParameters=max_dbd_msg_action
with another option after that. * Restore MCS label when suspended job is
resumed. * Fix insufficient lock levels. * slurmrestd - use errno from job
submission. * Fix "user" filter for sacctmgr show transactions. * Fix
preemption logic. * Fix no_consume GRES for exclusive (whole node)
requests. * Fix regression in 20.02 that caused an infinite loop in
slurmctld when requesting --distribution=plane for the job. * Fix parsing
of the --distribution option. * Add CONF READ_LOCK to
_handle_fed_send_job_sync. * prep/script - always call slurmctld PrEp
callback in _run_script(). * Fix node estimation for jobs that use GPUs or
--cpus-per-task. * Fix jobcomp, job_submit and cli_filter Lua
implementation plugins causing slurmctld and/or job submission CLI tools
segfaults due to bad return handling when the respective Lua script failed
to load. * Fix propagation of gpu options through hetjob components. * Add
SLURM_CLUSTERS environment variable to scancel. * Fix packing/unpacking of
"unlinked" jobs. * Connect slurmstepd's stderr to srun for steps launched
with --pty. * Handle MPS correctly when doing exclusive allocations. *
slurmrestd - fix compiling against libhttpparser in a non-default path. *
slurmrestd - avoid compilation issues with libhttpparser < 2.6. * Fix
compile issues when compiling slurmrestd without --enable-debug. * Reset
idle time on a reservation that is getting purged. * Fix reoccurring
reservations that have Purge_comp= to keep correct duration if they are
purged. * scontrol - changed the "PROMISCUOUS" flag to "MAGNETIC" * Early
return from epilog_set_env in case of no_consume. * Fix cons_common/
job_test start time discovery logic to prevent skewed results between "will
run test" executions. * Ensure TRESRunMins limits are maintained during
"scontrol reconfigure". * Improve error message when host lookup fails.
