-Subject: bcache: fix stack corruption by PRECEDING_KEY()
-
-Recently people report bcache code compiled with gcc9 is broken, one of
-the buggy behavior I observe is that two adjacent 4KB I/Os should merge
-into one but they don't. Finally it turns out to be a stack corruption
-caused by macro PRECEDING_KEY().
-
-See how PRECEDING_KEY() is defined in bset.h,
-437 #define PRECEDING_KEY(_k)                                       \
-438 ({                                                              \
-439         struct bkey *_ret = NULL;                               \
-440                                                                 \
-441         if (KEY_INODE(_k) || KEY_OFFSET(_k)) {                  \
-442                 _ret = &KEY(KEY_INODE(_k), KEY_OFFSET(_k), 0);  \
-443                                                                 \

-445                         _ret->high--;                           \
-446                 _ret->low--;                                    \
-447         }                                                       \
-448                                                                 \
-449         _ret;                                                   \
-450 })
-
-At line 442, _ret points to address of a on-stack variable combined by
-KEY(), the life range of this on-stack variable is in line 442-446,
-once _ret is returned to bch_btree_insert_key(), the returned address
-points to an invalid stack address and this address is overwritten in
-the following called bch_btree_iter_init(). Then argument 'search' of
-bch_btree_iter_init() points to some address inside stackframe of
-bch_btree_iter_init(), exact address depends on how the compiler
-allocates stack space. Now the stack is corrupted.
