2020-08-04coccinelle: api: filter out memdup_user definitionsDenis Efremov1-4/+13
Don't match memdup_user/vmemdup_user. Signed-off-by: Denis Efremov <efremov@linux.com> Signed-off-by: Julia Lawall <Julia.Lawall@inria.fr>
2020-08-04coccinelle: api: extend memdup_user rule with vmemdup_user()Denis Efremov1-0/+45
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 <efremov@linux.com>
2020-08-04coccinelle: api: extend memdup_user transformation with GFP_USERDenis Efremov1-2/+6
Match GFP_USER and optional __GFP_NOWARN allocations with memdup_user.cocci rule. Commit 6c2c97a24f09 ("memdup_user(): switch to GFP_USER") switched memdup_user() from GFP_KERNEL to GFP_USER. In almost all cases it is still a good idea to recommend memdup_user() for GFP_KERNEL allocations. The motivation behind altering memdup_user() to GFP_USER: https://lkml.org/lkml/2018/1/6/333 Signed-off-by: Denis Efremov <efremov@linux.com> Signed-off-by: Julia Lawall <Julia.Lawall@inria.fr>

2016-10-01Coccinelle: limit memdup_user transformation to GFP_KERNEL caseJulia Lawall1-4/+4
Memdup_user encapsulates a memory allocation with the flag GFP_KERNEL, so only allow this flag in the original code. Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: Michal Marek <mmarek@suse.com>

2012-01-15scripts/coccinelle: improve the coverage of some semantic patchesJulia Lawall1-7/+32
