coccinelle: api: kfree_sensitive: print memset position

2020-10-10T19:26:12Z

Print memset() call position in addition to the kfree() position to ease issues identification. Signed-off-by: Denis Efremov Signed-off-by: Julia Lawall

coccinelle: api: add kvmalloc script

2020-10-01T19:46:55Z

Suggest kvmalloc, kvfree instead of opencoded patterns. Signed-off-by: Denis Efremov Signed-off-by: Julia Lawall

coccinelle: api: update kzfree script to kfree_sensitive

2020-09-12T15:08:43Z

Commit 453431a54934 ("mm, treewide: rename kzfree() to kfree_sensitive()") renames kzfree to kfree_sensitive and uses memzero_explicit(...) instead of memset(..., 0, ...) internally. Update cocci script to reflect these changes. Signed-off-by: Denis Efremov Signed-off-by: Julia Lawall

coccinelle: add patch rule for dma_alloc_coherent

2020-08-21T20:35:40Z

Commit dfd32cad146e ("dma-mapping: remove dma_zalloc_coherent()") removed the definition of dma_zalloc_coherent() and also removed the corresponding patch rule for replacing instances of dma_alloc_coherent + memset in zalloc-simple.cocci (though left the report rule). Add a new patch rule to remove unnecessary calls to memset after allocating with dma_alloc_coherent. While we're at it, fix a couple of typos.

coccinelle: api: extend memdup_user rule with vmemdup_user()

2020-08-04T20:46:59Z

Add vmemdup_user() transformations to the memdup_user.cocci rule. Commit 50fd2f298bef ("new primitive: vmemdup_user()") introduced vmemdup_user(). The function uses kvmalloc with GPF_USER flag. Signed-off-by: Denis Efremov
