HSI: core: Fix return freed object in hsi_new_client

2022-01-27T07:46:17Z

[ Upstream commit a1ee1c08fcd5af03187dcd41dcab12fd5b379555 ] cl is freed on error of calling device_register, but this object is return later, which will cause uaf issue. Fix it by return NULL on error. Signed-off-by: Chengfeng Ye Signed-off-by: Sebastian Reichel Signed-off-by: Sasha Levin

HSI: core: fix resource leaks in hsi_add_client_from_dt()

2021-05-22T08:38:24Z

[ Upstream commit 5c08b0f75575648032f309a6f58294453423ed93 ] If some of the allocations fail between the dev_set_name() and the device_register() then the name will not be freed. Fix this by moving dev_set_name() directly in front of the call to device_register().

hsi: correctly handle return value of kzalloc

2015-10-19T09:42:02Z

Since kzalloc can be failed in memory pressure, its return value should be checked and handled. Signed-off-by: Insu Yun Signed-off-by: Sebastian Reichel

hsi: fix double kfree

2015-10-14T11:22:00Z

When device_register() fails, kfree() is called in hsi_client_release(), hence there is no need to call kfree in err3 again. Fixes: a2aa24734d9db ("HSI: Add common DT binding for HSI client devices") Signed-off-by: Geliang Tang Signed-off-by: Sebastian Reichel

HSI: export method to (un)register clients

2014-05-15T22:54:41Z

Expose method for registering and unregistering HSI clients, so that client drivers can register other client drivers. This is useful for HSI drivers, which want to use the functionality of other HSI drivers. For example the N900 modem driver can load HSI drivers for mcsaab protocol and speech protocol.

hsi: convert bus code to use dev_groups

2013-10-17T01:36:04Z

The dev_attrs field of struct bus_type is going away soon, dev_groups should be used instead. This converts the hsi code to use the correct field. Cc: Andrew Morton Cc: Kees Cook Signed-off-by: Greg Kroah-Hartman

drivers: avoid format string in dev_set_name

2013-07-03T23:07:41Z

Calling dev_set_name with a single paramter causes it to be handled as a format string. Many callers are passing potentially dynamic string content, so use "%s" in those cases to avoid any potential accidents, including wrappers like device_create*() and bdi_register().
