When I tried to run xfstests test, kernel oops happen. Can you run xfstests and check kernel oops ? These are my xfstests command and tests. sudo ./check cifs/001 generic/001 generic/002 generic/005 generic/006 generic/007 generic/008 generic/011 generic/013 generic/014 generic/020 generic/023 generic/024 generic/028 generic/029 generic/030 generic/032 generic/033 generic/036 generic/037 generic/069 generic/070 generic/071 generic/074 generic/080 generic/084 generic/086 generic/095 generic/098 generic/100 generic/103 generic/109 generic/113 generic/117 generic/124 generic/125 generic/129 generic/130 generic/132 generic/133 generic/135 generic/141 generic/169 generic/198 generic/207 generic/208 generic/210 generic/211 generic/212 generic/214 generic/215 generic/221 generic/225 generic/228 generic/236 generic/239 generic/241 generic/245 generic/246 generic/247 generic/248 generic/249 generic/257 generic/258 generic/286 generic/308 generic/309 generic/310 generic/313 generic/315 generic/316 generic/337 generic/339 generic/340 generic/344 generic/345 generic/346 generic/349 generic/350 generic/354 generic/360 generic/377 generic/391 generic/393 generic/394 generic/406 generic/412 generic/420 generic/422 generic/432 generic/433 generic/436 generic/437 generic/438 generic/439 generic/443 generic/445 generic/446 generic/448 generic/451 generic/452 generic/454 generic/460 generic/464 generic/465 generic/490 generic/504 generic/523 generic/524 generic/533 generic/539 generic/567 generic/568 generic/590 generic/591 Thanks! > > Hyunchul Lee (1): > ksmbd: add buffer validation for SMB2_CREATE_CONTEXT > > Namjae Jeon (9): > ksmbd: add the check to vaildate if stream protocol length exceeds > maximum value > ksmbd: add validation in smb2_ioctl > ksmbd: use correct basic info level in set_file_basic_info() > ksmbd: add request buffer validation in smb2_set_info > ksmbd: check strictly data area in ksmbd_smb2_check_message() > ksmbd: add validation in smb2 negotiate > ksmbd: remove the leftover of smb2.0 dialect support > ksmbd: remove NTLMv1 authentication > ksmbd: fix transform header validation > > Ralph Boehme (10): > ksmbd: use ksmbd_req_buf_next() in ksmbd_smb2_check_message() > ksmbd: use ksmbd_req_buf_next() in ksmbd_verify_smb_message() > ksmbd: remove ksmbd_verify_smb_message() > ksmbd: add ksmbd_smb2_cur_pdu_buflen() > ksmbd: use ksmbd_smb2_cur_pdu_buflen() in ksmbd_smb2_check_message() > ksmbd: check PDU len is at least header plus body size in > ksmbd_smb2_check_message() > ksmdb: use cmd helper variable in smb2_get_ksmbd_tcon() > ksmdb: make smb2_get_ksmbd_tcon() callable with chained PDUs > ksmbd: make smb2_check_user_session() callabe for compound PDUs > ksmdb: move session and tcon validation to ksmbd_smb2_check_message() > > fs/ksmbd/auth.c | 205 --------------------- > fs/ksmbd/connection.c | 9 +- > fs/ksmbd/crypto_ctx.c | 16 -- > fs/ksmbd/crypto_ctx.h | 8 - > fs/ksmbd/ksmbd_work.h | 1 + > fs/ksmbd/oplock.c | 41 ++++- > fs/ksmbd/server.c | 19 +- > fs/ksmbd/smb2misc.c | 164 ++++++++++------- > fs/ksmbd/smb2ops.c | 5 - > fs/ksmbd/smb2pdu.c | 411 ++++++++++++++++++++++++++++++------------ > fs/ksmbd/smb2pdu.h | 11 +- > fs/ksmbd/smb_common.c | 68 +++---- > fs/ksmbd/smb_common.h | 5 +- > fs/ksmbd/smbacl.c | 21 ++- > fs/ksmbd/vfs.c | 2 +- > fs/ksmbd/vfs.h | 2 +- > 16 files changed, 496 insertions(+), 492 deletions(-) > > -- > 2.31.1 > >
v2: - update comments of smb2_get_data_area_len(). - fix wrong buffer size check in fsctl_query_iface_info_ioctl(). - fix 32bit overflow in smb2_set_info. v3: - add buffer check for ByteCount of smb negotiate request. - Moved buffer check of to the top of loop to avoid unneeded behavior when out_buf_len is smaller than network_interface_info_ioctl_rsp. - get correct out_buf_len which doesn't exceed max stream protocol length. - subtract single smb2_lock_element for correct buffer size check in ksmbd_smb2_check_message(). v4: - use work->response_sz for out_buf_len calculation in smb2_ioctl. - move smb2_neg size check to above to validate NegotiateContextOffset field. - remove unneeded dialect checks in smb2_sess_setup() and smb2_handle_negotiate(). - split smb2_set_info patch into two patches(declaring smb2_file_basic_info and buffer check) v5: - remove PDU size validation from ksmbd_conn_handler_loop() - add PDU size validation to ksmbd_smb2_check_message() - fix compound non-related request handling Hyunchul Lee (1): ksmbd: add buffer validation for SMB2_CREATE_CONTEXT Namjae Jeon (9): ksmbd: add the check to vaildate if stream protocol length exceeds maximum value ksmbd: add validation in smb2_ioctl ksmbd: use correct basic info level in set_file_basic_info() ksmbd: add request buffer validation in smb2_set_info ksmbd: check strictly data area in ksmbd_smb2_check_message() ksmbd: add validation in smb2 negotiate ksmbd: remove the leftover of smb2.0 dialect support ksmbd: remove NTLMv1 authentication ksmbd: fix transform header validation Ralph Boehme (10): ksmbd: use ksmbd_req_buf_next() in ksmbd_smb2_check_message() ksmbd: use ksmbd_req_buf_next() in ksmbd_verify_smb_message() ksmbd: remove ksmbd_verify_smb_message() ksmbd: add ksmbd_smb2_cur_pdu_buflen() ksmbd: use ksmbd_smb2_cur_pdu_buflen() in ksmbd_smb2_check_message() ksmbd: check PDU len is at least header plus body size in ksmbd_smb2_check_message() ksmdb: use cmd helper variable in smb2_get_ksmbd_tcon() ksmdb: make smb2_get_ksmbd_tcon() callable with chained PDUs ksmbd: make smb2_check_user_session() callabe for compound PDUs ksmdb: move session and tcon validation to ksmbd_smb2_check_message() fs/ksmbd/auth.c | 205 --------------------- fs/ksmbd/connection.c | 9 +- fs/ksmbd/crypto_ctx.c | 16 -- fs/ksmbd/crypto_ctx.h | 8 - fs/ksmbd/ksmbd_work.h | 1 + fs/ksmbd/oplock.c | 41 ++++- fs/ksmbd/server.c | 19 +- fs/ksmbd/smb2misc.c | 164 ++++++++++------- fs/ksmbd/smb2ops.c | 5 - fs/ksmbd/smb2pdu.c | 411 ++++++++++++++++++++++++++++++------------ fs/ksmbd/smb2pdu.h | 11 +- fs/ksmbd/smb_common.c | 68 +++---- fs/ksmbd/smb_common.h | 5 +- fs/ksmbd/smbacl.c | 21 ++- fs/ksmbd/vfs.c | 2 +- fs/ksmbd/vfs.h | 2 +- 16 files changed, 496 insertions(+), 492 deletions(-)
