net: llc: fix skb_over_panic

2021-08-04T09:56:46Z

[ Upstream commit c7c9d2102c9c098916ab9e0ab248006107d00d6c ] Syzbot reported skb_over_panic() in llc_pdu_init_as_xid_cmd(). The problem was in wrong LCC header manipulations. Syzbot's reproducer tries to send XID packet. llc_ui_sendmsg() is doing following steps: 1. skb allocation with size = len + header size len is passed from userpace and header size is 3 since addr->sllc_xid is set. 2. skb_reserve() for header_len = 3 3. filling all other space with memcpy_from_msg() Ok, at this moment we have fully loaded skb, only headers needs to be filled. Then code comes to llc_sap_action_send_xid_c(). This function pushes 3 bytes for LLC PDU header and initializes it. Then comes llc_pdu_init_as_xid_cmd(). It initalizes next 3 bytes *AFTER* LLC PDU header and call skb_push(skb, 3). This looks wrong for 2 reasons: 1. Bytes rigth after LLC header are user data, so this function was overwriting payload. 2. skb_push(skb, 3) call can cause skb_over_panic() since all free space was filled in llc_ui_sendmsg(). (This can happen is user passed 686 len: 686 + 14 (eth header) + 3 (LLC header) = 703. SKB_DATA_ALIGN(703) = 704) So, in this patch I added 2 new private constansts: LLC_PDU_TYPE_U_XID and LLC_PDU_LEN_U_XID. LLC_PDU_LEN_U_XID is used to correctly reserve header size to handle LLC + XID case. LLC_PDU_TYPE_U_XID is used by llc_pdu_header_init() function to push 6 bytes instead of 3. And finally I removed skb_push() call from llc_pdu_init_as_xid_cmd(). This changes should not affect other parts of LLC, since after all steps we just transmit buffer.

cfg80211: Fix possible memory leak in function cfg80211_bss_update

2021-08-04T09:56:46Z

commit f9a5c358c8d26fed0cc45f2afc64633d4ba21dff upstream. When we exceed the limit of BSS entries, this function will free the new entry, however, at this time, it is the last door to access the inputed ies, so these ies will be unreferenced objects and cause memory leak. Therefore we should free its ies before deallocating the new entry, beside of dropping it from hidden_list.

NIU: fix incorrect error return, missed in previous revert

2021-08-04T09:56:45Z

commit 15bbf8bb4d4ab87108ecf5f4155ec8ffa3c141d6 upstream. Commit 7930742d6, reverting 26fd962, missed out on reverting an incorrect change to a return value. The niu_pci_vpd_scan_props(..) == 1 case appears to be a normal path - treating it as an error and return -EINVAL was breaking VPD_SCAN and causing the driver to fail to load. Fix, so my Neptune card works again. Cc: Kangjie Lu Cc: Shannon Nelson Cc: David S.
