Subject: CVE request: kernel: splice local denial of service

Hi oss-sec,

CVE Request for a local denial kernel issue....

The splice(2) syscall has received some fixes against local deadlocks.

2.6.30-rc3 is fixed,
2.6.27.24 is fixed, and
2.6.29.4 is fixed.

The inode double locking code was introduced in 2.6.19, so I guess earlier
kernel versions are not affected. (Miklos?)

Its as far as I understand this set of changes in mainline:
