parisc: pdc_stable: Constify struct kobj_type

2024-09-09T06:53:17+00:00

This 'struct kobj_type' is not modified. It is only used in kobject_init_and_add() which takes a 'const struct kobj_type *ktype' parameter. Constifying this structure and moving it to a read-only section, and can increase over all security. Signed-off-by: Hongbo Li Signed-off-by: Helge Deller

parisc: pdc_stable: use strscpy() to instead of strncpy()

2023-01-09T08:51:56+00:00

The implementation of strscpy() is more robust and safer. That's now the recommended way to copy NUL-terminated strings. Signed-off-by: Xu Panda Signed-off-by: Yang Yang Signed-off-by: Helge Deller

parisc: Use signed char for hardware path in pdc.h

2022-10-21T07:15:20+00:00

Clean up the struct for hardware_path and drop the struct device_path with a proper assignment of bc[] and mod members as signed chars. This patch prepares for the kbuild change from Jason A. Donenfeld to treat char as always unsigned. Signed-off-by: Helge Deller Cc: Jason A. Donenfeld

parisc: pdc_stable: Fix memory leak in pdcs_register_pathentries

2022-01-21T21:48:54+00:00

kobject_init_and_add() takes reference even when it fails. According to the doc of kobject_init_and_add()： If this function returns an error, kobject_put() must be called to properly clean up the memory associated with the object. Fix memory leak by calling kobject_put(). Fixes: 73f368cf679b ("Kobject: change drivers/parisc/pdc_stable.c to use kobject_init_and_add") Signed-off-by: Miaoqian Lin Signed-off-by: Helge Deller

parisc: pdc_stable: use default_groups in kobj_type

2022-01-07T00:29:22+00:00

There are currently 2 ways to create a set of sysfs files for a kobj_type, through the default_attrs field, and the default_groups field. Move the parisc pdc_stable sysfs code to use default_groups field which has been the preferred way since aa30f47cf666 ("kobject: Add support for default attribute groups to kobj_type") so that we can soon get rid of the obsolete default_attrs field.
