hello, Renaud,
thank you for bringing this up. indeed, 62aa34f8f8a5 ("Move jitter to use proper state locking/thread signaling")
is in the v6.9 of rng-tools while RHEL8 has 6.8-3.el8 version. we will look into backporting the fix or rebasing
rng-tools in the RHEL8.5 and probably earlier minor versions.
mis-click: hello, Renaud, i've build a test package with a fix backported. could you please test it on your laptop where the bug reproduces reliably? currently this package is on testing, but i believe it is good enough to become a released version. http://people.redhat.com/~vdronov/bz1956248/ Hi Vladis, Unfortunately I cannot reproduce, nor the customer that reported this. I asked him to forward the package to his own customers that may be experiencing this. Renaud. Thanks, Renaud. Meanwhile I'll work on getting the fixed package to the RHEL-8.5 and probably on a backport to -8.4. Hello, I cannot reproduce the problem on x86_64 (intel-denlow-r-02) with rng-tools-6.8-4.el8.x86_64 - latest non-fixed version (bug description mentions rng-tools-6.7-2.fc30.x86_64, but it is not available in RHEL). Do we know how to reproduce this bug, or are we okay with SanityOnly? hello, Vilem, rng-tools-6.8-4.el8.x86_64 actually has this bug fixed, -5.el8 version adds a small "fix for a fix" only. the problem version is 6.8-3.el8. unfortunately, as reporter mentions, the issue reproduces only at his laptop, i.e. on a certain hw configuration. the guess is that it can be related to a presence of a TPM module (see #c0). with that, the SanityOnly would be fine, as the fix itself is simple and straightforward and it was tested in Fedora since v6.9 (i.e. for a couple of years). thank you. Okay, let's consider this verified + sanityonly. We're actually hitting this on many RHV VMs with RHEL8.3 and 8.4 Latest rng-tools available in release channels is rng-tools-6.8-3.el8.x86_64 thank you for an update, Roel. the rng-tools-6.8-5.el8 update with the fix is being pushed to the RHEL-8.4.z repos currently. Hi, I see similar behaviour on Linux localhost.localdomain 5.12.13-200.fc33.x86_64 #1 SMP Wed Jun 23 16:20:26 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux Currently killing the process after startup to get rid of the core load. (In reply to rfge from comment #21) > I see similar behaviour on Linux localhost.localdomain > 5.12.13-200.fc33.x86_64 #1 SMP Wed Jun 23 16:20:26 UTC 2021 x86_64 x86_64 > x86_64 GNU/Linux hello, rfge, this is too little information to do any reasonable conclusions. can we start with versions of rng-tools and jitterentropy where the problem is? # rpm -qa rng-tools jitterentropy if these are rng-tools-6.13 and jitterentropy-3.x from testing repo, then most probably this is an issue in the bz1974132. in this case i would like to request the output of: # lscpu (basically i need to know the CPU model and how much active cores [LCPUs] do you have) # dmidecode then could you please follow the request in bz1974132#c1? this will give an idea if your issue is the same or a new fresh shiny one. thank you. Hi Vladis, What did you expect. I never even was aware that I used/needed rngd, let alone that I understood what its needed for, until I noticed its behaviour. Just thought it might be useful to know. Anyway, I can provide part of the information you ask for but I do not find the time to follow the request in bz1974132#c1 right now. I will try to provide feedback on that request asap. For now, hope this enlightens... -------- 8< ---------------- 8< ---------------- 8< ---------------- 8< ------- >> rpm -qa rng-tools jitterentropy output >> $ rpm -qa rng-tools jitterentropy jitterentropy-3.0.2-1.fc33.x86_64 rng-tools-6.13-2.fc33.x86_64 -------- 8< ---------------- 8< ---------------- 8< ---------------- 8< ------- >> lscpu output >> $ lscpu Architectuur: x86_64 CPU-modus(sen): 32-bit, 64-bit Bytevolgorde: Little Endian Address sizes: 43 bits physical, 48 bits virtual CPU's: 16 Online CPU's-lijst: 0-15 Draden per kern: 2 Kernen per voet: 8 CPU-voeten: 1 NUMA-nodes: 1 Producent-ID: AuthenticAMD CPU-familie: 23 Model: 113 Modelnaam: AMD Ryzen 7 3700X 8-Core Processor Stepping: 0 Frequency boost: enabled CPU-frequentie (MHz): 2200.000 max.

Unfortunately, it is unclear if you see the same issue, as your system is a modern one and 16 cores are active. Anyway, I've just revoked jitterentropy-3.0.2-1.fc33.x86_64 and rng-tools-6.13-2.fc33.x86_64 update from f34/33 since they have a known issue and am going to post an update when the jitter-lib is fixed. So, if you need rng-tools running, you could downgrade back to the previous releases which are now in stable and testing - rng-tools-6.12 and jitterentropy-2. Also, please let me note, that probably you do not need both rng-tools and jitterentropy. With the introduction of jitter-rng in the kernel as of v5.4-rc1 by 50ee7529ec45 we generally have enough entropy in all cases and do not need rngd to run in userspace anymore. Thus Fedora and RHEL have removed rng-tools from the installed-by-default standard and minimal package sets. rng-tools-6.13-1.git.d207e0b6.el8 for rhel-8.5.0-candidate: https://brewweb.engineering.redhat.com/brew/taskinfo?taskID=38803046 Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA. For information on the advisory (rng-tools bug fix and enhancement update), and where to find the updated files, follow the link below. If the solution does not work for you, open a new bug report. https://access.redhat.com/errata/RHBA-2021:4427 |
