NFC: hci: Split memcpy() of struct hcp_message flexible array

2022-09-27T14:45:18Z

To work around a misbehavior of the compiler's ability to see into composite flexible array structs (as detailed in the coming memcpy() hardening series[1]), split the memcpy() of the header and the payload so no false positive run-time overflow warning will be generated. This split already existed for the "firstfrag" case, so just generalize the logic further.

nfc: drop unneeded debug prints

2021-10-12T00:00:51Z

ftrace is a preferred and standard way to debug entering and exiting functions so drop useless debug prints. Signed-off-by: Krzysztof Kozlowski Signed-off-by: Jakub Kicinski

nfc: do not break pr_debug() call into separate lines

Remove unneeded line break between pr_debug and arguments. Signed-off-by: Krzysztof Kozlowski Signed-off-by: David S. Miller

nfc: constify local pointer variables

2021-07-30T15:22:52Z

Few pointers to struct nfc_target and struct nfc_se can be made const. Signed-off-by: Krzysztof Kozlowski Signed-off-by: Jakub Kicinski

nfc: constify several pointers to u8, char and sk_buff

2021-07-30T15:22:52Z

Several functions receive pointers to u8, char or sk_buff but do not modify the contents so make them const. This allows doing the same for local variables and in total makes the code a little bit safer. Signed-off-by: Krzysztof Kozlowski Signed-off-by: Jakub Kicinski

nfc: hci: annotate nfc_llc_init() as __init

2021-07-30T15:22:51Z

The nfc_llc_init() is used only in other __init annotated context. Signed-off-by: Krzysztof Kozlowski Signed-off-by: Jakub Kicinski

nfc: constify nfc_llc_ops

2021-07-25T08:21:21Z

Neither the core nor the drivers modify the passed pointer to struct nfc_llc_ops, so make it a pointer to const for correctness and safety. Signed-off-by: Krzysztof Kozlowski Signed-off-by: David S. Miller

nfc: constify nfc_hci_ops
