Bug ID: 2115
Summary: net/ntnic: mulitple issues detected with GCC
-fanalyzer
Product: DPDK
Version: 26.11
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: minor
Priority: Normal
Component: ethdev
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
23. net/ntnic: FPGA model constructors return unchecked malloc
Component: ethdev | Severity: minor | Confidence: single pass
nthw_fpga_model_new, nthw_module_new, nthw_register_new, nthw_field_new,
nthw_param_new (drivers/net/ntnic/nthw/model/nthw_fpga_model.c) return malloc()
directly and callers pass the result to *_init(), which dereferences it (:186,
:245, :296, :317, :418). Same in nthw_id_table_create()
(nthw/flow_api/flow_id_table.c:68, calloc dereferenced at :70).
24. net/ntnic: p_drv leaked on init failure
Component: ethdev | Severity: minor | Confidence: single pass
nthw_pci_dev_init() allocates p_drv at drivers/net/ntnic/ntnic_ethdev.c:2326
and stores it with store_pdrv() (:2380). The later return -1 paths (:2388,
:2437, :2456, ...) do not free it or clear the stored pointer.
25. net/ntnic: NULL check after dereference in nthw_pci_dev_deinit()
Component: ethdev | Severity: trivial | Confidence: confirmed
drivers/net/ntnic/ntnic_ethdev.c:2680 dereferences internals; :2688 then loops
on while (internals).
