ToDo List Kernel (2004.12.07 21:00:00)

We currently migrate to MediaWiki from our old installation, but not all content has been migrated yet. Take a look at the Wiki Team page for instructions how to help or browse through our new wiki at wiki.linux-vserver.org to find the information already migrated.

Stuff ToDo for the Kernel

• {005} check tagxid on ro filesystems/mounts
• {025} make VXCs required for CAPs

work in progress (mask capabilities)

• {010} add vfsmount tagxid=xx

(tag)xid=<xid> mounts implemented, but untested

• {002} unwire uid hashes

maybe other hashes are more important

• {020} do some decent profiling
• {020} check inode xid assignment and iattr scope

somewhat excercised with testfs.sh

• {010} CPU virtualization
• {020} vserver child reaper (initpid)

• {020} alternate solution for closing_wait (HZ)

maybe remove the entire patch?

• {015} accounting and limits for IPC stuff

shm, msq and locks for now (not all enforced)

• {015} look into acct_update_integrals()

some kind of per context integrals maybe?

• {020} reduce stack usage in some functions like

vs_reboot (424!), vc_ctx_kill (148), vc_set_ipv4root (144),

vs_context_state (104) (should be below 100 now ...)

• {010} move buffer[255] from sys_reboot into some do_reboot?
• {020} separate token bucket per cpu

• {005} virtualize /proc/locks (get_locks_status)

done, not really tested

• {005} replace hash locks by rw locks

• {010} add slab cache for vxi/nxi
• {010} check that SOCK_USER_SOCKET is used at all
• {010} fix the inode sizes inode->i_size = 64;
• {010} fix the sys32_sysinfo() for parisc32
• {010} revalidate checks in syscall commands
• {010} allow proc_dointvec_bset read without CAP_SYS_MODULE

• {010} find a solution for alpha's getxpid

solution is there (asm wrapper)

• {010} fix the um arch syscall (add it)

was fixed in mainline

• {010} VCMD_vx_set_vhi_name -> VCMD_set_vhi_name

done.
