5.10-stable review patch. If anyone has any objections, please let me know. ------------------ From: Archie Pusaka <apusaka@xxxxxxxxxxxx> [ Upstream commit fad646e16d3cafd67d3cfff8e66f77401190957e ] This patch replaces some non-inclusive terms based on the appropriate language mapping table compiled by the Bluetooth SIG: https://specificationrefs.bluetooth.com/language-mapping/Appropriate_Language_Mapping_Table.pdf Specifically, these terms are replaced: master -> initiator slave -> responder Signed-off-by: Archie Pusaka <apusaka@xxxxxxxxxxxx> Signed-off-by: Marcel Holtmann <marcel@xxxxxxxxxxxx> Stable-dep-of: 59b047bc9808 ("Bluetooth: MGMT/SMP: Fix address type when using SMP over BREDR/LE") Signed-off-by: Sasha Levin <sashal@xxxxxxxxxx> --- include/net/bluetooth/mgmt.h | 2 +- net/bluetooth/mgmt.c | 10 +++--- net/bluetooth/smp.c | 66 +++++++++++++++++++----------------- net/bluetooth/smp.h | 6 ++-- 4 files changed, 43 insertions(+), 41 deletions(-) diff --git a/include/net/bluetooth/mgmt.h b/include/net/bluetooth/mgmt.h index 6b55155e05e97..faaba22e0d386 100644 --- a/include/net/bluetooth/mgmt.h +++ b/include/net/bluetooth/mgmt.h @@ -202,7 +202,7 @@ struct mgmt_cp_load_link_keys { struct mgmt_ltk_info { struct mgmt_addr_info addr; __u8 type; - __u8 master; + __u8 initiator; __u8 enc_size; __le16 ediv; __le64 rand; diff --git a/net/bluetooth/mgmt.c b/net/bluetooth/mgmt.c index 878bf73822449..c62ea4c954645 100644 --- a/net/bluetooth/mgmt.c +++ b/net/bluetooth/mgmt.c @@ -5939,7 +5939,7 @@ static int load_irks(struct sock *sk, struct hci_dev *hdev, void *cp_data, static bool ltk_is_valid(struct mgmt_ltk_info *key) { - if (key->master != 0x00 && key->master != 0x01) + if (key->initiator != 0x00 && key->initiator != 0x01) return false; switch (key->addr.type) { @@ -6017,11 +6017,11 @@ static int load_long_term_keys(struct sock *sk, struct hci_dev *hdev, switch (key->type) { case MGMT_LTK_UNAUTHENTICATED: authenticated = 0x00; - type = key->master ?
