On a UML build, the igc_ptp driver uses CONFIG_X86_TSC for timestamp conversion. The function that is used is not available on UML builds, so have the function use the default system_counterval_t timestamp instead for UML builds.

Daniel Borkmann says: ==================== Minor managed neighbor follow-ups Minor follow-up series to address prior feedback from David and Jakub. Patch 1 adds a build time assertion to prevent overflows when shifting in extended flags, patch 2 is a cleanup to use NLA_POLICY_MASK instead of open-coding invalid flags rejection and patch 3 rejects creating new neighbors with NUD_PERMANENT & NTF_MANAGED. For details, see individual patches. ==================== Link: https://lore.kernel.org/r/20211013132140.11143-1-daniel@iogearbox.netSigned-off-by:

Daniel Borkmann authored
The combination of NUD_PERMANENT + NTF_MANAGED is not supported and does not make sense either given the former indicates a static/fixed neighbor entry whereas the latter a dynamically resolved one. While it is possible to transition from one over to the other, we should however reject such creation attempts.

Instead of open-coding a check for invalid bits in NTF_EXT_MASK, we can just use the NLA_POLICY_MASK() helper instead, and simplify NDA_FLAGS_EXT sanity check this way. Suggested-by:
-
Daniel Borkmann authored
Currently, NDA_FLAGS_EXT flags allow a maximum of 24 bits to be used for extended neighbor flags. These are eventually fed into neigh->flags by shifting with NTF_EXT_SHIFT as per commit 2c611ad9 ("net, neigh: Extend neigh->flags to 32 bit to allow for extensions"). If really ever needed in future, the full 32 bits from NDA_FLAGS_EXT can be used, it would only require to move neigh->flags from u32 to u64 inside the kernel. Add a build-time assertion such that when extending the NTF_EXT_MASK with new bits, we'll trigger an error once we surpass the 24th bit. This assumes that no bit holes in new NTF_EXT_* flags will slip in from UAPI, but I think this is reasonable to assume. Suggested-by:

PHY driver dp83867 has rich supports for OF-platform to fine-tune the PHY chip during phy configuration. However, for non-OF platform, certain PHY tunable parameters such as IO impedance and RX & TX internal delays are critical and should be initialized to its default during PHY driver probe. Tested-by:

It seems reasonable to fine-tune only some of the skew values when using one of the rgmii-*id PHY modes, and even when all skew values are specified, using the correct ID PHY mode makes sense for documentation purposes. Such a configuration also appears in the binding docs in Documentation/devicetree/bindings/net/micrel-ksz90x1.txt, so the driver should not warn about it. Signed-off-by:

random_ether_addr() was the original name of the helper which was kept for backward compatibility (?) after the rename in commit 0a4dd594 ("etherdevice: Rename random_ether_addr to eth_random_addr"). We have a single random_ether_addr() caller left in tree while there are 70 callers of eth_random_addr(). Time to drop this define. Reviewed-by:

This big patch sprinkles const on local variables and function arguments which may refer to netdev->dev_addr. Commit 406f42fa ("net-next: When a bond have a massive amount of VLANs...") introduced a rbtree for faster Ethernet address look up. To maintain netdev->dev_addr in this tree we need to make all the writes to it got through appropriate helpers. Some of the changes here are not strictly required - const is sometimes cast off but pointer is not used for writing. It seems like it's still better to add the const in case the code changes later or relevant -W flags get enabled for the build. No functional changes.

In icmp_build_probe(), the icmp_ext_echo_iio parsing should be done step by step and skb_header_pointer() return value should always be checked, this patch fixes 3 places in there: - On case ICMP_EXT_ECHO_CTYPE_NAME, it should only copy ident.name from skb by skb_header_pointer(), its len is ident_len. Besides, the return value of skb_header_pointer() should always be checked. - On case ICMP_EXT_ECHO_CTYPE_INDEX, move ident_len check ahead of skb_header_pointer(), and also do the return value check for skb_header_pointer(). - On case ICMP_EXT_ECHO_CTYPE_ADDR, before accessing iio->ident.addr. ctype3_hdr.addrlen, skb_header_pointer() should be called first, then check its return value and ident_len. On subcases ICMP_AFI_IP and ICMP_AFI_IP6, also do check for ident. addr.ctype3_hdr.addrlen and skb_header_pointer()'s return value. On subcase ICMP_AFI_IP, the len for skb_header_pointer() should be "sizeof(iio->extobj_hdr) + sizeof(iio->ident.addr.ctype3_hdr) + sizeof(struct in_addr)" or "ident_len". v1->v2: - To make it more clear, call skb_header_pointer() once only for iio->indent's parsing as Jakub Suggested. v2->v3: - The extobj_hdr.length check against sizeof(_iio) should be done before calling skb_header_pointer(), as Eric noticed.

The TX U.FL1 share the line with the SMA1 and the RX U.FL2 share line with the SMA2. This dependence is controlled by the ice_verify_pin_e810t.

sctp_make_strreset_req() makes repeated calls to sctp_addto_chunk() which will automatically account for padding on each call. inreq and outreq are already 4 bytes aligned, but the payload is not and doing SCTP_PAD4(a + b) (which _sctp_make_chunk() did implicitly here) is different from SCTP_PAD4(a) + SCTP_PAD4(b) and not enough.

Currently, mlxsw allows cooling states to be set above the maximum cooling state supported by the driver: # cat /sys/class/thermal/thermal_zone2/cdev0/type mlxsw_fan # cat /sys/class/thermal/thermal_zone2/cdev0/max_state 10 # echo 18 > /sys/class/thermal/thermal_zone2/cdev0/cur_state # echo $? 0 This results in out-of-bounds memory accesses when thermal state transition statistics are enabled (CONFIG_THERMAL_STATISTICS=y), as the transition table is accessed with a too large index (state) [1]. According to the thermal maintainer, it is the responsibility of the driver to reject such operations [2]. Therefore, return an error when the state to be set exceeds the maximum cooling state supported by the driver. To avoid dead code, as suggested by the thermal maintainer [3], partially revert commit a421ce08 ("mlxsw: core: Extend cooling device with cooling levels") that tried to interpret these invalid cooling states (above the maximum) in a special way. The cooling levels array is not removed in order to prevent the fans going below 20% PWM, which would cause them to get stuck at 0% PWM.

After recent cleanups, gcc started warning about a suspicious memcpy() call during the s2io_io_resume() function: In function '__dev_addr_set', inlined from 'eth_hw_addr_set' at include/linux/etherdevice.h:318:2, inlined from 's2io_set_mac_addr' at drivers/net/ethernet/neterion/s2io.c:5205:2, inlined from 's2io_io_resume' at drivers/net/ethernet/neterion/s2io.c:8569:7: arch/x86/include/asm/string_32.h:182:25: error: '__builtin_memcpy' accessing 6 bytes at offsets 0 and 2 overlaps 4 bytes at offset 2 [-Werror=restrict] 182 | #define memcpy(t, f, n) __builtin_memcpy(t, f, n) | ^~~~~~~~~~~~~~~~~~~~~~~~~ include/linux/netdevice.h:4648:9: note: in expansion of macro 'memcpy' 4648 | memcpy(dev->dev_addr, addr, len); | ^~~~~~ What apparently happened is that an old cleanup changed the calling conventions for s2io_set_mac_addr() from taking an ethernet address as a character array to taking a struct sockaddr, but one of the callers was not changed at the same time. Change it to instead call the low-level do_s2io_prog_unicast() function that still takes the old argument type.

Ido Schimmel says: ==================== mlxsw: Show per-band ECN-marked counter on qdisc The RED qdisc can expose number of packets that it has marked through the prob_marked counter (shown in iproute2 as "marked"). This counter currently just shows number of packets marked in the SW datapath, which in a switch deployment likely means zero. Spectrum-3 does support per-TC counters, and in this patchset, mlxsw supports this RED statistic properly. ==================== Link: https://lore.kernel.org/r/20211013103748.492531-1-idosch@idosch.orgSigned-off-by:

The Qdisc code in mlxsw used to report a number of packets ECN-marked on a port. Because reporting a per-port value as a per-TC value was misleading, this was removed in commit 8a29581e ("mlxsw: spectrum: Move the ECN-marked packet counter to ethtool"). On Spectrum-3, a per-TC number of ECN-marked packets is available in per-TC congestion counter group. Add a new array for the ECN counter, fetch the values from the per-TC congestion group, and pick the value indicated by tclass_num as appropriate. On Spectrum-1 and Spectrum-2, this per-TC value is not available, and zeroes will be reported, as they currently are. Signed-off-by:
