net: intel: Remove MODULE_AUTHORs

2024-07-11T17:05:52Z

We are moving away from the Sourceforge email address. Rather than removing or updating the email for the affected entries, remove the MODULE_AUTHOR altogether as its usage is incorrect [1].

net: intel: Use -y instead of -objs in Makefile

2024-06-11T02:52:44Z

*-objs suffix is reserved rather for (user-space) host programs while usually *-y suffix is used for kernel drivers (although *-objs works for that purpose for now). Let's correct the old usages of *-objs in Makefiles.

net: annotate writes on dev->mtu from ndo_change_mtu()

2024-05-07T23:19:14Z

Simon reported that ndo_change_mtu() methods were never updated to use WRITE_ONCE(dev->mtu, new_mtu) as hinted in commit 501a90c94510 ("inet: protect against too small mtu values.") We read dev->mtu without holding RTNL in many places, with READ_ONCE() annotations. It is time to take care of ndo_change_mtu() methods to use corresponding WRITE_ONCE() Signed-off-by: Eric Dumazet Reported-by: Simon Horman Closes: https://lore.kernel.org/netdev/20240505144608.GB67882@kernel.org/ Reviewed-by: Jacob Keller Reviewed-by: Sabrina Dubroca Reviewed-by: Simon Horman Acked-by: Shannon Nelson Link: https://lore.kernel.org/r/20240506102812.3025432-1-edumazet@google.com Signed-off-by: Jakub Kicinski

net: intel: implement modern PM ops declarations

2024-03-29T15:58:43Z

Switch the Intel networking drivers to use the new power management ops declaration formats and macros, which allows us to drop __maybe_unused, as well as a bunch of ifdef checking CONFIG_PM. This is safe to do because the compiler drops the unused functions, verified by checking for any of the power management function symbols being present in System.map for a build without CONFIG_PM. If a driver has runtime PM, define the ops with pm_ptr(), and if the driver has Simple PM, use pm_sleep_ptr(), as well as the new versions of the macros for declaring the members of the pm_ops structs. Checked with network-enabled allnoconfig, allyesconfig, allmodconfig on x64_64.

This series is introducing the use of FIELD_GET and FIELD_PREP which requires bitfield.h to be included. Fix all the includes in this one change, and rearrange includes into alphabetical order to ease readability and future maintenance. virtchnl.h and it's usage was modified to have it's own includes as it should.

e1000: replace deprecated strncpy with strscpy

2023-10-19T01:10:17Z

`strncpy` is deprecated for use on NUL-terminated destination strings [1] and as such we should prefer more robust and less ambiguous string interfaces. We can see that netdev->name is expected to be NUL-terminated based on it's usage with format strings: | pr_info("%s NIC Link is Down\n", | netdev->name); A suitable replacement is `strscpy` [2] due to the fact that it guarantees NUL-termination on the destination buffer without unnecessarily NUL-padding. This is in line with other uses of strscpy on netdev->name: $ rg "strscpy\(netdev\->name.*pci.*" drivers/net/ethernet/intel/e1000e/netdev.c 7455: strscpy(netdev->name, pci_name(pdev), sizeof(netdev->name)); drivers/net/ethernet/intel/ixgbe/ixgbe_main.c 10839: strscpy(netdev->name, pci_name(pdev), sizeof(netdev->name)); Link: https://www.kernel.org/doc/html/latest/process/deprecated.html#strncpy-on-nul-terminated-strings [1] Link: https://manpages.debian.org/testing/linux-manual-4.8/strscpy.9.en.html [2] Link: https://github.com/KSPP/linux/issues/90 Signed-off-by: Justin Stitt Signed-off-by: Jacob Keller Link: https://lore.kernel.org/r/20231017190411.2199743-5-jacob.e.keller@intel.com Signed-off-by: Jakub Kicinski

e1000: Remove unnecessary use of kmap_atomic()

2022-11-02T18:09:13Z

buffer_info->rxbuf.page accessed in e1000_clean_jumbo_rx_irq() is allocated using GFP_ATOMIC. Pages allocated with GFP_ATOMIC can't come from highmem and so there's no need to kmap() them. Just use page_address(). I don't have access to a 32-bit system so did some limited testing on qemu (qemu-system-i386 -m 4096 -smp 4 -device e1000e) with a 32-bit Debian 11.04 image.

net: drop the weight argument from netif_napi_add

2022-09-29T01:57:14Z

We tell driver developers to always pass NAPI_POLL_WEIGHT as the weight to netif_napi_add(). This may be confusing to newcomers, drop the weight argument, those who really need to tweak the weight can use netif_napi_add_weight().
