Still getting the WARNING message about low memlock limit despite having configured it according to the documentation

[giraudan]

Hello,

After implementing the modifications specified here and rebooting, I'm still getting this warning at startup:

[WARNING] your OS's memlock limit may be too low for you (current value: 16777216 bytes).
This may cause issues when importing third parties databases or dealing with tens of tokens.
For information on how to increase the memlock value, please have a look at https://github.com/paolostivanin/OTPClient/wiki/Secure-Memory-Limitations
couldn't lock 16384 bytes of memory (dh): Cannot allocate memory
Couldn't find the password in the secret service.

• I have pam_limits defined in multiple config files under /etc/pam.d:

$ grep -rni pam_limits /etc/pam.d/
/etc/pam.d/system-services:8:session   required    pam_limits.so
/etc/pam.d/system-auth:25:session    required                    pam_limits.so
/etc/pam.d/tigervnc:5:session    required     pam_limits.so

• I permanently modified the memlock limits for all users:

$ grep memlock /etc/security/limits.conf
* soft memlock 16384
* hard memlock 16384

• I checked, after rebooting, that ulimit -l returns the correct value:

$ ulimit -l
16384

Additional info:

• I'm using otpclient v3.2.1.
• I'm using an up-to-date archlinux

Am I doing something wrong?

Hello,
it's showing the warning because with the latest release I've increase the minimum amount of suggested secure memory.
You should use unlimited instead of 16384. I've updated the Wiki accordingly.

Thanks!

May I suggest to specify the username instead of * in /etc/security/limits.d/memlock.conf?

good idea!
