treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28+00:00

This is the result of running the Coccinelle script from scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to avoid scalar types (which need careful case-by-case checking), and instead replace kmalloc-family calls that allocate struct or union object instances: Single allocations: kmalloc(sizeof(TYPE), ...) are replaced with: kmalloc_obj(TYPE, ...) Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...) are replaced with: kmalloc_objs(TYPE, COUNT, ...) Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...) are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...) (where TYPE may also be *VAR) The resulting allocations no longer return "void *", instead returning "TYPE *". Signed-off-by: Kees Cook

ice: fix broken Rx on VFs

2025-11-26T03:26:27+00:00

Since the tagged commit, ice stopped respecting Rx buffer length passed from VFs. At that point, the buffer length was hardcoded in ice, so VFs still worked up to some point (until, for example, a VF wanted an MTU larger than its PF). The next commit 93f53db9f9dc ("ice: switch to Page Pool"), broke Rx on VFs completely since ice started accounting per-queue buffer lengths again, but now VF queues always had their length zeroed, as ice was already ignoring what iavf was passing to it. Restore the line that initializes the buffer length on VF queues basing on the virtchnl messages.

ice: implement GTP RSS context tracking and configuration

2025-11-06T22:19:43+00:00

This commit implements the core RSS context management and configuration logic for GTP (GTPU) protocol support in VF RSS operations. Key implementation features: - GTPU hash context management with pre/post processing functions - Context index calculation and mapping for different GTPU scenarios - Integration with main RSS configuration flow via wrapper functions - Support for IPv4/IPv6 GTPU RSS configurations - Rollback mechanism for handling RSS rule conflicts - Hash context reset and cleanup functionality The implementation provides comprehensive GTPU RSS support by: 1. Adding ice_add_rss_cfg_pre_gtpu() for preprocessing GTPU contexts 2. Adding ice_add_rss_cfg_post_gtpu() for postprocessing configurations 3. Adding ice_calc_gtpu_ctx_idx() for context index calculation 4. Integrating GTPU logic into ice_add_rss_cfg_wrap() and ice_rem_rss_cfg_wrap() 5. Supporting context tracking in VF hash_ctx structures This completes the GTP RSS infrastructure enabling VFs to configure RSS hashing on GTP-encapsulated traffic.

ice: drop page splitting and recycling

2025-10-29T20:53:12+00:00

As part of the transition toward Page Pool integration, remove the legacy page splitting and recycling logic from the ice driver. This mirrors the approach taken in commit 920d86f3c552 ("iavf: drop page splitting and recycling"). The previous model attempted to reuse partially consumed pages by splitting them and tracking their usage across descriptors. While this was once a memory optimization, it introduced significant complexity and overhead in the Rx path, including: - Manual refcount management and page reuse heuristics; - Per-descriptor buffer shuffling, which could involve moving dozens of `ice_rx_buf` structures per NAPI cycle; - Increased branching and cache pressure in the hotpath. This change simplifies the Rx logic by always allocating fresh pages and letting the networking stack handle their lifecycle. Although this may temporarily reduce performance (up to ~98% in some XDP cases), it greatly improves maintainability and paves the way for Page Pool, which will restore and exceed previous performance levels. The `ice_rx_buf` array is retained for now to minimize diffstat and ease future replacement with a shared buffer abstraction.

ice: Remove deprecated ice_lag_move_new_vf_nodes() call

2025-09-19T15:42:08+00:00

Moving the code to handle the LAG part of a VF reset to helper functions deprecated the function ice_lag_move_new_vf_nodes(). The cleanup missed a call to this function in the error path of ice_vc_cfg_qs_msg(). In the case that would end in the error path, a NULL pointer would be encountered due to the empty list of netdevs for members of the aggregate. Remove the unnecessary call to ice_lag_move_new_vf_nodes(), and since this is the only call to this function, remove the function as well.

ice: add E830 Earliest TxTime First Offload support

2025-09-19T15:42:07+00:00

E830 supports Earliest TxTime First (ETF) hardware offload, which is configured via the ETF Qdisc on a per-queue basis (see tc-etf(8)). ETF introduces a new Tx flow mechanism that utilizes a timestamp ring (tstamp_ring) alongside the standard Tx ring. This timestamp ring is used to indicate when hardware will transmit a packet. Tx Time is supported on the first 2048 Tx queues of the device, and the NVM image limits the maximum number of Tx queues to 2048 for the device. The allocation and initialization of the timestamp ring occur when the feature is enabled on a specific Tx queue via tc-etf. The requested Tx Time queue index cannot be greater than the number of Tx queues (vsi->num_txq). To support ETF, the following flags and bitmap are introduced: - ICE_F_TXTIME: Device feature flag set for E830 NICs, indicating ETF support. - txtime_txqs: PF-level bitmap set when ETF is enabled and cleared when disabled for a specific Tx queue. It is used by ice_is_txtime_ena() to check if ETF is allocated and configured on any Tx queue, which is checked during Tx ring allocation. - ICE_TX_FLAGS_TXTIME: Per Tx ring flag set when ETF is allocated and configured for a specific Tx queue. It determines ETF status during packet transmission and is checked by ice_is_txtime_ena() to verify if ETF is enabled on any Tx queue. Due to a hardware issue that can result in a malicious driver detection event, additional timestamp descriptors are required when wrapping around the timestamp ring. Up to 64 additional timestamp descriptors are reserved, reducing the available Tx descriptors. To accommodate this, ICE_MAX_NUM_DESC_BY_MAC is introduced, defining: - E830: Maximum Tx descriptor count of 8096 (8K - 32 - 64 for timestamp fetch descriptors). - E810 and E82X: Maximum Tx descriptor count of 8160 (8K - 32).
