Description

The inode double locking code in fs/ocfs2/file.c in the Linux kernel 2.6.30 before 2.6.30-rc3, 2.6.27 before 2.6.27.24, 2.6.29 before 2.6.29.4, and possibly other versions down to 2.6.19 allows local users to cause a denial of service (prevention of file creation and removal) via a series of splice system calls that trigger a deadlock between the generic_file_splice_write, splice_from_pipe, and ocfs2_file_splice_write functions.

Affected

Our own answer: ranges merged, affected separated from platform-only, with confidence and review flags.

v ≤ 2.6.192.6.27 ≤ v < 2.6.27.242.6.29 ≤ v < 2.6.29.42.6.30 rc12.6.30 rc2
Affected range stops below 2.6.27.24, so it looks safe — our inference, not a vendor statement
Affected range stops below 2.6.29.4, so it looks safe — our inference, not a vendor statement
