tools/lib/lockdep: Reduce MAX_LOCK_DEPTH to avoid overflowing lock_chain/: Depth

2017-07-21T05:42:20Z

commit 98dcea0cfd04e083ac74137ceb9a632604740e2d upstream. liblockdep has been broken since commit 75dd602a5198 ("lockdep: Fix lock_chain::base size"), as that adds a check that MAX_LOCK_DEPTH is within the range of lock_chain::depth and in liblockdep it is much too large. That should have resulted in a compiler error, but didn't because: - the check uses ARRAY_SIZE(), which isn't yet defined in liblockdep so is assumed to be an (undeclared) function - putting a function call inside a BUILD_BUG_ON() expression quietly turns it into some nonsense involving a variable-length array It did produce a compiler warning, but I didn't notice because liblockdep already produces too many warnings if -Wall is enabled (which I'll fix shortly). Even before that commit, which reduced lock_chain::depth from 8 bits to 6, MAX_LOCK_DEPTH was too large.

tools/lib/lockdep: Add userspace version of READ_ONCE()

2016-02-29T09:29:27Z

This was added to the kernel code in <1658d35ead5d> ("list: Use READ_ONCE() when testing for empty lists"). There's nothing special we need to do about it in userspace.

tools/liblockdep: explicitly declare lockdep API we call from liblockdep

2015-11-06T21:01:37Z

It seems that newer gcc complains about lack of explicit declaration for some of the API we use, add it in. Signed-off-by: Sasha Levin

tools/liblockdep: add userspace versions of WRITE_ONCE and RCU_INIT_POINTER

2015-11-06T21:01:36Z

These were added to the kernel code in cee34d88c ("lockdep: Fix a race between /proc/lock_stat and module unload"). There's nothing special we need to do about them in userspace. Signed-off-by: Sasha Levin

tools/liblockdep: Use the rbtree header provided by common tools headers

2015-08-25T07:44:23Z

Recent changes to rbtree.h may break compilation. There is no reason to use a liblockdep specific header to begin with, so we'll use the one shared with all other tools/.

tools/liblockdep: Correct macro for WARN

2015-08-25T07:44:22Z

As Peter Zijlstra pointed out, the varargs for WARN() are optional, so we need to correctly handle the case where they don't exist. This would cause a compilation error.

tools/liblockdep: Fix compilation error

Recent changes to kernel/locking/lockdep.c broke the liblockdep build. Fix that. Signed-off-by: Eunbong Song Signed-off-by: Sasha Levin

tools: Consolidate types.h

2014-05-01T19:22:39Z

Combine all definitions into a common tools/include/linux/types.h and kill the wild growth elsewhere. Move DECLARE_BITMAP to its proper bitmap.h header.

tools: Unify export.h

2014-05-01T19:18:17Z

So tools/ has been growing three, at a different stage of their development export.h headers and so we should unite into one. Add tools/include/ to the include path of virtio and liblockdep to pick the shared header now.

tools/liblockdep: Ignore asmlinkage and visible

2014-04-01T15:46:09Z

Commit 63f9a7fde7 "asmlinkage: Make lockdep_sys_exit asmlinkage" has added asmlinkage annotation to lockdep_sys_exit, which broke build of liblockdep. Since we don't need asmlinkage in liblockep, just ignore it. Reported-by: Eunbong Song Reported-by: Robin Hack Signed-off-by: Sasha Levin
