So 2.3 is out and so we can start implementing new quota file format. My proposal is following:
struct quota_file_header {
u32 qfh_Magic;
u32 qfh_Version;
};
qfh_Magic would identify quota file so we can be sure it is really ours... Currently we will use 2 magics
- for user and for group quota file.
qfh_Version is I think clear.
struct quota_time_limits {
u64 qfd_btime;
u64 qfd_itime;
};
This entry will specify time limits after which soft-quota becomes hard-quota. Currently this times are
stored in root's structure but as we are going to have capabilities I think it's better to have nonexeptional
structure for UID 0.
struct quota_block {
u32 qb_curblocks, qb_bhardlimit, qb_bsoftlimit;
same for inodes
u64 qb_btime, qb_time;
};
This is same as it was before except the thing we have 64-bits for time.
I would propose to have also special structure for inmemory copy of quota_block which would be same as is know -
ie. time_t for times... Maybe uint for limits?
Any suggestions are welcome?
Honza.
