2025-04-16cxgb4: fix memory leak in cxgb4_init_ethtool_filters() error pathAbdun Nihaal
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.

2025-04-16xfrm: Add explicit dev to .xdo_dev_state_{add,delete,free}Cosmin Ratiu
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.

-Wflex-array-member-not-at-end was introduced in GCC-14, and we are getting ready to enable it, globally. Change the type of the middle struct member currently causing trouble from `struct ethtool_link_settings` to `struct ethtool_link_settings_hdr`. 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.

Since struct ethtool_ts_info is in include/uapi/linux/ethtool.h, here we introduce the kernel-only structure in include/linux/ethtool.h.

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull thermal control updates from Rafael Wysocki: "These mostly change the thermal core in a few ways allowing thermal drivers to be simplified, in particular in their removal and failing probe handling parts that are notoriously prone to errors, and propagate the changes to several drivers. Apart from that, support for a new platform is added (Intel Lunar Lake-M), some bugs are fixed and some code is cleaned up, as usual. Specifics: - Store zone trips table and zone operations directly in struct thermal_zone_device (Rafael Wysocki) - Fix up flex array initialization during thermal zone device registration (Nathan Chancellor) - Rework writable trip points handling in the thermal core and several drivers (Rafael Wysocki) - Thermal core code cleanups (Dan Carpenter, Flavio Suligoi) - Use thermal zone accessor functions in the int340x Intel thermal driver (Rafael Wysocki) - Add Lunar Lake-M PCI ID to the int340x Intel thermal driver (Srinivas Pandruvada) - Minor fixes for thermal governors (Rafael Wysocki, Di Shen) - Trip point handling fixes for the iwlwifi wireless driver (Rafael Wysocki) - Code cleanups (Rafael J.

2024-02-27thermal: core: Eliminate writable trip points masksRafael J. Wysocki
All of the thermal_zone_device_register_with_trips() callers pass zero writable trip points masks to it, so drop the mask argument from that function and update all of its callers accordingly. This also removes the artificial trip points per zone limit of 32, related to using writable trip points masks. No intentional functional impact. Signed-off-by: Rafael J.

2023-12-13net: ethtool: pass a pointer to parameters to get/set_rxfh ethtool opsAhmed Zaki
The get/set_rxfh ethtool ops currently takes the rxfh (RSS) parameters as direct function arguments. This will force us to change the API (and all drivers' functions) every time some new parameters are added. This is part 1/2 of the fix, as suggested in [1]: - First simplify the code by always providing a pointer to all params (indir, key and func); the fact that some of them may be NULL seems like a weird historic thing or a premature optimization. It will simplify the drivers if all pointers are always present. - Then make the functions take a dev pointer, and a pointer to a single struct wrapping all arguments. The set_* should also take an extack.

2023-10-11netdev: replace napi_reschedule with napi_scheduleChristian Marangi
Now that napi_schedule return a bool, we can drop napi_reschedule that does the same exact function. The function comes from a very old commit bfe13f54f502 ("ibm_emac: Convert to use napi_struct independent of struct net_device") and the purpose is actually deprecated in favour of different logic. Convert every user of napi_reschedule to napi_schedule.

2023-06-15net: tls: make the offload check helper take skb not socketJakub Kicinski
All callers of tls_is_sk_tx_device_offloaded() currently do an equivalent of: if (skb->sk && tls_is_skb_tx_device_offloaded(skb->sk)) Have the helper accept skb and do the skb->sk check locally. Two drivers have local static inlines with similar wrappers already. While at it change the ifdef condition to TLS_DEVICE. Only TLS_DEVICE selects SOCK_VALIDATE_XMIT, so the two are equivalent. This makes removing the duplicated IS_ENABLED() check in funeth more obviously correct.
