* net: annotate writes on dev->mtu from ndo_change_mtu()Eric Dumazet2024-05-083-3/+3
| | | | | | | | | | | | | | | | | | | | | | | 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 <edumazet@google.com> Reported-by: Simon Horman <horms@kernel.org> Closes: https://lore.kernel.org/netdev/20240505144608.GB67882@kernel.org/ Reviewed-by: Jacob Keller <jacob.e.keller@intel.com> Reviewed-by: Sabrina Dubroca <sd@queasysnail.net> Reviewed-by: Simon Horman <horms@kernel.org> Acked-by: Shannon Nelson <shannon.nelson@amd.com> Link: https://lore.kernel.org/r/20240506102812.3025432-1-edumazet@google.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>

* | net: ethtool: pass a pointer to parameters to get/set_rxfh ethtool opsAhmed Zaki2023-12-145-74/+92
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | strncpy() is deprecated for use on NUL-terminated destination strings [1] and as such we should prefer more robust and less ambiguous string interfaces. `desc` is expected to be NUL-terminated as evident by the manual NUL-byte assignment. Moreover, NUL-padding does not seem to be necessary. The only caller of efx_mcdi_nvram_metadata() is efx_devlink_info_nvram_partition() which provides a NULL for `desc`: | rc = efx_mcdi_nvram_metadata(efx, partition_type, NULL, version, NULL, 0); Due to this, I am not sure this code is even reached but we should still favor something other than strncpy. Considering the above, a suitable replacement is `strscpy` [2] due to the fact that it guarantees NUL-termination on the destination buffer without unnecessarily NUL-padding.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a foreign LHS rule (TC rule from a tunnel netdev which requests conntrack lookup) matches on inner headers or enc_key_id, these matches cannot be performed by the Outer Rule table, as the keys are only available after the tunnel type has been identified (by the OR lookup) and the rest of the headers parsed accordingly. Offload such rules with an Action Rule, using the LOOKUP_CONTROL section of the AR response to specify the conntrack and/or recirculation actions, combined with an Outer Rule which performs only the usual Encap Match duties. This processing flow, as it requires two AR lookups per packet, is less performant than OR-CT-AR, so only use it where necessary.

Make sure to populate the error message in these cases. In practice this does us no good as TC indirect block callbacks don't come with an extack to fill in; but maybe they will someday and when debugging it's possible to provide a fake extack and emit its message to the console.

| * sfc: check for zero length in EF10 RX prefixEdward Cree2023-09-011-5/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When EF10 RXDP firmware is operating in cut-through mode, packet length is not known at the time the RX prefix is generated, so it is left as zero and RX event merging is inhibited to ensure that the length is available in the RX event. However, it has been found that in certain circumstances the RX events for these packets still get merged, meaning the driver cannot read the length from the RX event, and tries to use the length from the prefix. The resulting zero-length SKBs cause crashes in GRO since commit 1d11fa696733 ("net-gro: remove GRO_DROP"), so add a check to the driver to detect these zero-length RX events and discard the packet.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Patch series "mm: ioremap: Convert architectures to take GENERIC_IOREMAP way", v8. Motivation and implementation: ============================== Currently, many architecutres have't taken the standard GENERIC_IOREMAP way to implement ioremap_prot(), iounmap(), and ioremap_xx(), but make these functions specifically under each arch's folder. Those cause many duplicated code of ioremap() and iounmap(). In this patchset, firstly introduce generic_ioremap_prot() and generic_iounmap() to extract the generic code for GENERIC_IOREMAP. By taking GENERIC_IOREMAP method, the generic generic_ioremap_prot(), generic_iounmap(), and their generic wrapper ioremap_prot(), ioremap() and iounmap() are all visible and available to arch. Arch needs to provide wrapper functions to override the generic version if there's arch specific handling in its corresponding ioremap_prot(), ioremap() or iounmap(). With these changes, duplicated ioremap/iounmap() code uder ARCH-es are removed, and the equivalent functioality is kept as before. Background info: ================ 1) The converting more architectures to take GENERIC_IOREMAP way is suggested by Christoph in below discussion: https://lore.kernel.org/all/Yp7h0Jv6vpgt6xdZ@infradead.org/T/#u 2) In the previous v1 to v3, it's basically further action after arm64 has converted to GENERIC_IOREMAP way in below patchset. It's done by adding hook ioremap_allowed() and iounmap_allowed() in ARCH to add ARCH specific handling the middle of ioremap_prot() and iounmap(). [PATCH v5 0/6] arm64: Cleanup ioremap() and support ioremap_prot() https://lore.kernel.org/all/20220607125027.44946-1-wangkefeng.wang@huawei.com/T/#u Later, during v3 reviewing, Christophe Leroy suggested to introduce generic_ioremap_prot() and generic_iounmap() to generic codes, and ARCH can provide wrapper function ioremap_prot(), ioremap() or iounmap() if needed. Christophe made a RFC patchset as below to specially demonstrate his idea. This is what v4 and now v5 is doing. [RFC PATCH 0/8] mm: ioremap: Convert architectures to take GENERIC_IOREMAP way https://lore.kernel.org/all/cover.1665568707.git.christophe.leroy@csgroup.eu/T/#u Testing: ======== In v8, I only applied this patchset onto the latest linus's tree to build and run on arm64 and s390. This patch (of 19): Let's use '#define ioremap_xx' and "#ifdef ioremap_xx" instead. To remove defined ARCH_HAS_IOREMAP_xx macros in <asm/io.h> of each ARCH, the ARCH's own ioremap_wc|wt|np definition need be above "#include <asm-generic/iomap.h>. Otherwise the redefinition error would be seen during compiling. So the relevant adjustments are made to avoid compiling error: loongarch: - doesn't include <asm-generic/iomap.h>, defining ARCH_HAS_IOREMAP_WC is redundant, so simply remove it. m68k: - selected GENERIC_IOMAP, <asm-generic/iomap.h> has been added in <asm-generic/io.h>, and <asm/kmap.h> is included above <asm-generic/iomap.h>, so simply remove ARCH_HAS_IOREMAP_WT defining. mips: - move "#include <asm-generic/iomap.h>" below ioremap_wc definition in <asm/io.h> powerpc: - remove "#include <asm-generic/iomap.h>" in <asm/io.h> because it's duplicated with the one in <asm-generic/io.h>, let's rely on the latter. x86: - selected GENERIC_IOMAP, remove #include <asm-generic/iomap.h> in the middle of <asm/io.h>. Let's rely on <asm-generic/io.h>.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Existing comment in the source explains why we don't want efx_init_tc() failure to be fatal.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Access to the connection tracking table in EF100 hardware is through a "generic" table mechanism, whereby a firmware call at probe time gives the driver a description of the field widths and offsets, so that the driver can then construct key and response bitstrings at runtime. Probe the NIC for this information and populate the needed metadata into a new meta_ct field of struct efx_tc_state.
