Doc Text: |
If a large amount of sudo rules with a combined size that exceeded 265 KB was configured on the system, due to the way the sss_packet_grow() function computed the total length of a response packet, SSSD failed with a "Unable to create response: Invalid argument" error message. With this update, the sss_package_grow() function code has been fixed to properly compute the response packet length, and SSSD no longer fails in the aforementioned scenario.

Description

Steps to reproduce: 1. create large amount of large rules so that their combined size exceeds 265KB 2. run sssd 3. login as sudo user associated with these rules 4. $ sudo -l User user-1 is not allowed to run sudo on client. In sssd_sudo.log you will see: [sudosrv_cmd_send_reply] (0x0020): Unable to create response: Invalid argument Fixed upstream. Verified and automated the bug on SSSD version : sssd-1.9.2-127.el6.x86_64 Steps followed during verification: 1. Created hundreds of different groups with an ldap user as member to all. 2. Assigned large sudo rules to all the groups, thereby associating the ldap user with numerous sudo rules. 3. Reproduced the bug with older build by executing "sudo -l". Got the following error message in sssd_sudo.log: # cat /var/log/sssd/sssd_sudo.log | grep "Invalid argument" (Wed Sep 11 16:08:14 2013) [sssd[sudo]] [sudosrv_cmd_send_reply] (0x0020): Unable to create response: Invalid argument (Wed Sep 11 16:09:06 2013) [sssd[sudo]] [sudosrv_cmd_send_reply] (0x0020): Unable to create response: Invalid argument See the automated beaker output of the bug: :::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::: :: [ LOG ] :: Bug 1002161 - large number of sudo rules results in error :::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::: :: [ PASS ] :: Running '> /var/log/sssd/sssd_sudo.log' Stopping sssd: [ OK ] [ OK ] sssd: [ OK ] :: [07:16:08] :: Sleeping for 5 seconds :: [ PASS ] :: Running 'restart_clearing_cache' sudo_test_user:*:13111:10021:Kuch toh:/home/sudo_test_user:/bin/bash :: [ PASS ] :: Running 'getent passwd -s sss sudo_test_user' [sudo] password for sudo_test_user: :: [ PASS ] :: User can execute sudo command :: [ PASS ] :: File '/var/log/sssd/sssd_sudo.log' should not contain 'Unable to create response: Invalid argument' NOTE: With the latest build, user is able to execute sudo commands successfully.
