2026-02-21Convert more 'alloc_obj' cases to default GFP_KERNEL argumentsLinus Torvalds
This converts some of the visually simpler cases that have been split over multiple lines. I only did the ones that are easy to verify the resulting diff by having just that final GFP_KERNEL argument on the next line. Somebody should probably do a proper coccinelle script for this, but for me the trivial script actually resulted in an assertion failure in the middle of the script. I probably had made it a bit _too_ trivial. So after fighting that far a while I decided to just do some of the syntactically simpler cases with variations of the previous 'sed' scripts. The more syntactically complex multi-line cases would mostly really want whitespace cleanup anyway. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2026-02-21Convert 'alloc_flex' family to use the new default GFP_KERNEL argumentLinus Torvalds
This is the exact same thing as the 'alloc_obj()' version, only much smaller because there are a lot fewer users of the *alloc_flex() interface. As with alloc_obj() version, this was done entirely with mindless brute force, using the same script, except using 'flex' in the pattern rather than 'objs*'.

2026-02-21Convert 'alloc_obj' family to use the new default GFP_KERNEL argumentLinus Torvalds
This was done entirely with mindless brute force, using git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' | xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/' to convert the new alloc_obj() users that had a simple GFP_KERNEL argument to just drop that argument. Note that due to the extreme simplicity of the scripting, any slightly more complex cases spread over multiple lines would not be triggered: they definitely exist, but this covers the vast bulk of the cases, and the resulting diff is also then easier to check automatically. For the same reason the 'flex' versions will be done as a separate conversion. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2026-02-21treewide: Replace kmalloc with kmalloc_obj for non-scalar typesKees Cook
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 <kees@kernel.org>

git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next Pull networking updates from Paolo Abeni: "Core & protocols: - A significant effort all around the stack to guide the compiler to make the right choice when inlining code, to avoid unneeded calls for small helper and stack canary overhead in the fast-path. This generates better and faster code with very small or no text size increases, as in many cases the call generated more code than the actual inlined helper. - Extend AccECN implementation so that is now functionally complete, also allow the user-space enabling it on a per network namespace basis. - Add support for memory providers with large (above 4K) rx buffer. Paired with hw-gro, larger rx buffer sizes reduce the number of buffers traversing the stack, dincreasing single stream CPU usage by up to ~30%. - Do not add HBH header to Big TCP GSO packets. This simplifies the RX path, the TX path and the NIC drivers, and is possible because user-space taps can now interpret correctly such packets without the HBH hint. - Allow IPv6 routes to be configured with a gateway address that is resolved out of a different interface than the one specified, aligning IPv6 to IPv4 behavior. - Multi-queue aware sch_cake. This makes it possible to scale the rate shaper of sch_cake across multiple CPUs, while still enforcing a single global rate on the interface. - Add support for the nbcon (new buffer console) infrastructure to netconsole, enabling lock-free, priority-based console operations that are safer in crash scenarios. - Improve the TCP ipv6 output path to cache the flow information, saving cpu cycles, reducing cache line misses and stack use. - Improve netfilter packet tracker to resolve clashes for most protocols, avoiding unneeded drops on rare occasions. - Add IP6IP6 tunneling acceleration to the flowtable infrastructure. - Reduce tcp socket size by one cache line. - Notify neighbour changes atomically, avoiding inconsistencies between the notification sequence and the actual states sequence. - Add vsock namespace support, allowing complete isolation of vsocks across different network namespaces. - Improve xsk generic performances with cache-alignment-oriented optimizations. - Support netconsole automatic target recovery, allowing netconsole to reestablish targets when underlying low-level interface comes back online. Driver API: - Support for switching the working mode (automatic vs manual) of a DPLL device via netlink. - Introduce PHY ports representation to expose multiple front-facing media ports over a single MAC. - Introduce "rx-polarity" and "tx-polarity" device tree properties, to generalize polarity inversion requirements for differential signaling. - Add helper to create, prepare and enable managed clocks. Device drivers: - Add Huawei hinic3 PF etherner driver. - Add DWMAC glue driver for Motorcomm YT6801 PCIe ethernet controller. - Add ethernet driver for MaxLinear MxL862xx switches - Remove parallel-port Ethernet driver. - Convert existing driver timestamp configuration reporting to hwtstamp_get and remove legacy ioctl(). - Convert existing drivers to .get_rx_ring_count(), simplifing the RX ring count retrieval.

Remove <linux/hex.h> from <linux/kernel.h> and update all users/callers of hex.h interfaces to directly #include <linux/hex.h> as part of the process of putting kernel.h on a diet. Removing hex.h from kernel.h means that 36K C source files don't have to pay the price of parsing hex.h for the roughly 120 C source files that need it. This change has been build-tested with allmodconfig on most ARCHes. Also, all users/callers of <linux/hex.h> in the entire source tree have been updated if needed (if not already #included).

2026-01-15chelsio: Use new AES library APIEric Biggers
Switch from the old AES library functions (which use struct crypto_aes_ctx) to the new ones (which use struct aes_enckey). This eliminates the unnecessary computation and caching of the decryption round keys. The new AES en/decryption functions are also much faster and use AES instructions when supported by the CPU. Note that in addition to the change in the key preparation function and the key struct type itself, the change in the type of the key struct results in aes_encrypt() (which is temporarily a type-generic macro) calling the new encryption function rather than the old one.

2025-11-25cxgb4: Rename sched_class to avoid type clashAlan Maguire
drivers/net/ethernet/chelsio/cxgb4/sched.h declares a sched_class struct which has a type name clash with struct sched_class in kernel/sched/sched.h (a type used in a field in task_struct). When cxgb4 is a builtin we end up with both sched_class types, and as a result of this we wind up with DWARF (and derived from that BTF) with a duplicate incorrect task_struct representation. When cxgb4 is built-in this type clash can cause kernel builds to fail as resolve_btfids will fail when confused which task_struct to use. See [1] for more details. As such, renaming sched_class to ch_sched_class (in line with other structs like ch_sched_flowc) makes sense.

2025-11-24treewide: Drop pci_save_state() after pci_restore_state()Lukas Wunner
In 2009, commit c82f63e411f1 ("PCI: check saved state before restore") changed the behavior of pci_restore_state() such that it became necessary to call pci_save_state() afterwards, lest recovery from subsequent PCI errors fails. The commit has just been reverted and so all the pci_save_state() after pci_restore_state() calls that have accumulated in the tree are now superfluous. Drop them. Two drivers chose a different approach to achieve the same result: drivers/scsi/ipr.c and drivers/net/ethernet/intel/e1000e/netdev.c set the pci_dev's "state_saved" flag to true before calling pci_restore_state().

2025-10-30cxgb4: flower: add support for fragmentationHarshita V Rajput
This patch adds support for matching fragmented packets in tc flower filters. Previously, commit 93a8540aac72 ("cxgb4: flower: validate control flags") added a check using flow_rule_match_has_control_flags() to reject any rules with control flags, as the driver did not support fragmentation at that time. Now, with this patch, support for FLOW_DIS_IS_FRAGMENT is added: - The driver checks for control flags using flow_rule_is_supp_control_flags(), as recommended in commit d11e63119432 ("flow_offload: add control flag checking helpers"). - If the fragmentation flag is present, the driver sets `fs->val.frag` and `fs->mask.frag` accordingly in the filter specification. Since fragmentation is now supported, the earlier check that rejected all control flags (flow_rule_match_has_control_flags()) has been removed.

2025-10-28net: cxgb4/ch_ipsec: fix potential use-after-free in ↵Pavel Zhigulin
ch_ipsec_xfrm_add_state() callback In ch_ipsec_xfrm_add_state() there is not check of try_module_get return value. It is very unlikely, but try_module_get() could return false value, which could cause use-after-free error. Conditions: The module count must be zero, and a module unload in progress.

Convert to use .ndo_hwtstamp_get()/.ndo_hwtstamp_set() callbacks. There is some change in the logic as well. Previously, the driver was storing newly requested configuration regardless of whether it was applied or not. In case of request validation error, inconsistent configuration would be returned by the driver. New logic stores configuration only if was properly validated and applied. It brings the consistency between reported and actual configuration.

2025-04-17net: ethtool: Adjust exactly ETH_GSTRING_LEN-long stats to use memcpyKees Cook
Many drivers populate the stats buffer using C-String based APIs (e.g. ethtool_sprintf() and ethtool_puts()), usually when building up the list of stats individually (i.e. with a for() loop). This, however, requires that the source strings be populated in such a way as to have a terminating NUL byte in the source. Other drivers populate the stats buffer directly using one big memcpy() of an entire array of strings. No NUL termination is needed here, as the bytes are being directly passed through. Yet others will build up the stats buffer individually, but also use memcpy(). This, too, does not need NUL termination of the source strings. However, there are cases where the strings that populate the source stats strings are exactly ETH_GSTRING_LEN long, and GCC 15's -Wunterminated-string-initialization option complains that the trailing NUL byte has been truncated. This situation is fine only if the driver is using the memcpy() approach. If the C-String APIs are used, the destination string name will have its final byte truncated by the required trailing NUL byte applied by the C-string API. For drivers that are already using memcpy() but have initializers that truncate the NUL terminator, mark their source strings as __nonstring to silence the GCC warnings. For drivers that have initializers that truncate the NUL terminator and are using the C-String APIs, switch to memcpy() to avoid destination string truncation and mark their source strings as __nonstring to silence the GCC warnings. (Also introduce ethtool_cpy() as a helper to make this an easy replacement). Specifically the following warnings were investigated and addressed: ../drivers/net/ethernet/chelsio/cxgb/cxgb2.c:364:9: warning: initializer-string for array of 'char' truncates NUL terminator but destination lacks 'nonstring' attribute (33 chars into 32 available) [-Wunterminated-string-initialization] 364 | "TxFramesAbortedDueToXSCollisions", | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ../drivers/net/ethernet/freescale/enetc/enetc_ethtool.c:165:33: warning: initializer-string for array of 'char' truncates NUL terminator but destination lacks 'nonstring' attribute (33 chars into 32 available) [-Wunterminated-string-initialization] 165 | { ENETC_PM_R1523X(0), "MAC rx 1523 to max-octet packets" }, | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ../drivers/net/ethernet/freescale/enetc/enetc_ethtool.c:190:33: warning: initializer-string for array of 'char' truncates NUL terminator but destination lacks 'nonstring' attribute (33 chars into 32 available) [-Wunterminated-string-initialization] 190 | { ENETC_PM_T1523X(0), "MAC tx 1523 to max-octet packets" }, | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ../drivers/net/ethernet/google/gve/gve_ethtool.c:76:9: warning: initializer-string for array of 'char' truncates NUL terminator but destination lacks 'nonstring' attribute (33 chars into 32 available) [-Wunterminated-string-initialization] 76 | "adminq_dcfg_device_resources_cnt", "adminq_set_driver_parameter_cnt", | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ../drivers/net/ethernet/stmicro/stmmac/stmmac_ethtool.c:117:53: warning: initializer-string for array of 'char' truncates NUL terminator but destination lacks 'nonstring' attribute (33 chars into 32 available) [-Wunterminated-string-initialization] 117 | STMMAC_STAT(ptp_rx_msg_type_pdelay_follow_up), | ^ ../drivers/net/ethernet/stmicro/stmmac/stmmac_ethtool.c:46:12: note: in definition of macro 'STMMAC_STAT' 46 | { #m, sizeof_field(struct stmmac_extra_stats, m), \ | ^ ../drivers/net/ethernet/mellanox/mlxsw/spectrum_ethtool.c:328:24: warning: initializer-string for array of 'char' truncates NUL terminator but destination lacks 'nonstring' attribute (33 chars into 32 available) [-Wunterminated-string-initialization] 328 | .str = "a_mac_control_frames_transmitted", | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ../drivers/net/ethernet/mellanox/mlxsw/spectrum_ethtool.c:340:24: warning: initializer-string for array of 'char' truncates NUL terminator but destination lacks 'nonstring' attribute (33 chars into 32 available) [-Wunterminated-string-initialization] 340 | .str = "a_pause_mac_ctrl_frames_received", | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Signed-off-by: Kees Cook <kees@kernel.org> Reviewed-by: Petr Machata <petrm@nvidia.com> # for mlxsw Reviewed-by: Harshitha Ramamurthy <hramamurthy@google.com> Link: https://patch.msgid.link/20250416010210.work.904-kees@kernel.org Signed-off-by: Jakub Kicinski <kuba@kernel.org>

In the for loop used to allocate the loc_array and bmap for each port, a memory leak is possible when the allocation for loc_array succeeds, but the allocation for bmap fails. This is because when the control flow goes to the label free_eth_finfo, only the allocations starting from (i-1)th iteration are freed. Fix that by freeing the loc_array in the bmap allocation error path.

Previously, device driver IPSec offload implementations would fall into two categories: 1. Those that used xso.dev to determine the offload device. 2. Those that used xso.real_dev to determine the offload device. The first category didn't work with bonding while the second did. In a non-bonding setup the two pointers are the same. This commit adds explicit pointers for the offload netdevice to .xdo_dev_state_add() / .xdo_dev_state_delete() / .xdo_dev_state_free() which eliminates the confusion and allows drivers from the first category to work with bonding. xso.real_dev now becomes a private pointer managed by the bonding driver.

Additionally, update the type of some variables in various functions that don't access the flexible-array member, changing them to the newly created `struct ethtool_link_settings_hdr`. These changes are needed because the type of the conflicting middle members changed. So, those instances that expect the type to be `struct ethtool_link_settings` should be adjusted to the newly created type `struct ethtool_link_settings_hdr`. Also, adjust variable declarations to follow the reverse xmas tree convention.

2024-10-15cxgb4: Remove unused cxgb4_get_srq_entryDr. David Alan Gilbert
cxgb4_get_srq_entry() has been unused since 2018's commit e47094751ddc ("cxgb4: Add support to initialise/read SRQ entries") which added it. Remove it. Note: I'm a bit suspicious whether any of the srq code in there actually does anything useful; without this get I can't see anything that reads the data, so perhaps the whole thing should go? But that however would remove one of the opcode handlers, and I have no way to test that.
