Should be not possible to load conflicting DDP profiles. Only DDP profiles of the same group (not 0) can be loaded together; If DDP profile group is 0, it is exclusive, i.e. it cannot be loaded with any other DDP profile; If DDP profile groups are different - these profiles cannot be loaded together;
Fixes: b319712f53c8 ("net/i40e: extended list of operations for DDP processing") v3: prevent registration of read-only profiles with profile list Signed-off-by: Kirill Rybalchenko <kirill.rybalche...@intel.com> --- drivers/net/i40e/rte_pmd_i40e.c | 40 ++++++++++++++++++++++++++++++++++++---- 1 file changed, 36 insertions(+), 4 deletions(-) diff --git a/drivers/net/i40e/rte_pmd_i40e.c b/drivers/net/i40e/rte_pmd_i40e.c index 5436db4..dae59e6 100644 --- a/drivers/net/i40e/rte_pmd_i40e.c +++ b/drivers/net/i40e/rte_pmd_i40e.c @@ -1496,7 +1496,14 @@ i40e_check_profile_info(uint16_t port, uint8_t *profile_info_sec) struct rte_pmd_i40e_profile_info *pinfo, *p; uint32_t i; int ret; + static const uint32_t group_mask = 0x00ff0000; + pinfo = (struct rte_pmd_i40e_profile_info *)(profile_info_sec + + sizeof(struct i40e_profile_section_header)); + if (pinfo->track_id == 0) { + PMD_DRV_LOG(INFO, "Read-only profile."); + return 0; + } buff = rte_zmalloc("pinfo_list", (I40E_PROFILE_INFO_SIZE * I40E_MAX_PROFILE_NUM + 4), 0); @@ -1515,8 +1522,6 @@ i40e_check_profile_info(uint16_t port, uint8_t *profile_info_sec) return -1; } p_list = (struct rte_pmd_i40e_profile_list *)buff; - pinfo = (struct rte_pmd_i40e_profile_info *)(profile_info_sec + - sizeof(struct i40e_profile_section_header)); for (i = 0; i < p_list->p_count; i++) { p = &p_list->p_info[i]; if (pinfo->track_id == p->track_id) { @@ -1525,6 +1530,23 @@ i40e_check_profile_info(uint16_t port, uint8_t *profile_info_sec) return 1; } } + for (i = 0; i < p_list->p_count; i++) { + p = &p_list->p_info[i]; + if ((p->track_id & group_mask) == 0) { + PMD_DRV_LOG(INFO, "Profile of the group 0 exists."); + rte_free(buff); + return 2; + } + } + for (i = 0; i < p_list->p_count; i++) { + p = &p_list->p_info[i]; + if ((pinfo->track_id & group_mask) != + (p->track_id & group_mask)) { + PMD_DRV_LOG(INFO, "Profile of different group exists."); + rte_free(buff); + return 3; + } + } rte_free(buff); return 0; @@ -1544,6 +1566,7 @@ rte_pmd_i40e_process_ddp_package(uint16_t port, uint8_t *buff, uint8_t *profile_info_sec; int is_exist; enum i40e_status_code status = I40E_SUCCESS; + static const uint32_t type_mask = 0xff000000; if (op != RTE_PMD_I40E_PKG_OP_WR_ADD && op != RTE_PMD_I40E_PKG_OP_WR_ONLY && @@ -1595,6 +1618,10 @@ rte_pmd_i40e_process_ddp_package(uint16_t port, uint8_t *buff, return -EINVAL; } + /* force read-only track_id for type 0 */ + if ((track_id & type_mask) == 0) + track_id = 0; + /* Find profile segment */ profile_seg_hdr = i40e_find_segment_in_package(SEGMENT_TYPE_I40E, pkg_hdr); @@ -1628,12 +1655,17 @@ rte_pmd_i40e_process_ddp_package(uint16_t port, uint8_t *buff, if (op == RTE_PMD_I40E_PKG_OP_WR_ADD) { if (is_exist) { - PMD_DRV_LOG(ERR, "Profile already exists."); + if (is_exist == 1) + PMD_DRV_LOG(ERR, "Profile already exists."); + else if (is_exist == 2) + PMD_DRV_LOG(ERR, "Profile of group 0 already exists."); + else if (is_exist == 3) + PMD_DRV_LOG(ERR, "Profile of different group already exists"); rte_free(profile_info_sec); return -EEXIST; } } else if (op == RTE_PMD_I40E_PKG_OP_WR_DEL) { - if (!is_exist) { + if (is_exist != 1) { PMD_DRV_LOG(ERR, "Profile does not exist."); rte_free(profile_info_sec); return -EACCES; -- 2.5.5
