Linus Torvalds 76597cd314 proc: fix oops on invalid /proc/<pid>/maps access ... When m_start returns an error, the seq_file logic will still call m_stop with that error entry, so we'd better make sure that we check it before using it as a vma. Introduced by commit ec6fd8a435 ("report errors in /proc/*/*map* sanely"), which replaced NULL with various ERR_PTR() cases. (On ia64, you happen to get a unaligned fault instead of a page fault, since the address used is generally some random error code like -EPERM) Reported-by: Anca Emanuel <anca.emanuel@gmail.com> Reported-by: Tony Luck <tony.luck@intel.com> Cc: Al Viro <viro@zeniv.linux.org.uk> Cc: Américo Wang <xiyou.wangcong@gmail.com> Cc: Stephen Wilson <wilsons@start.ca> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>		14 years ago
