Description David Howells 2006-02-17 06:16:15 EST
Description of problem:  
The key quota detection in key allocation only fails if *both* quotas are 
exceeded (there's a total space quota and a key count quota). 
Version-Release number of selected component (if applicable):  
How reproducible:  
Steps to Reproduce:  
1. key session - 
2. for ((i=1; i<101; i++)); do keyctl add user $i "a" @s; done 
3. cat /proc/key-users 
Actual results:  
Allocates all the keys successfully and attaches them to the session keyring. 
It can then be seen in step 3 that the key count quota has been exceeded. 
NOTE! This assumes that other pre-existing keys owned by this user won't 
already have shoved the key space quota into excess. 
Expected results:  
The excess key allocations should give a "Disk quota exceeded" error, 
and /proc/key-users should show that the number of keys allocated to that user 
maxes out at the quota.
