2022-07-25net: ethernet: mtk-ppe: fix traffic offload with bridged wlanLorenzo Bianconi1-17/+13
A typical flow offload scenario for OpenWrt users is routed traffic received by the wan interface that is redirected to a wlan device belonging to the lan bridge. Current implementation fails to fill wdma offload info in mtk_flow_get_wdma_info() since odev device is the local bridge. Fix the issue running dev_fill_forward_path routine in mtk_flow_get_wdma_info in order to identify the wlan device.

Currently, the reading of FRC values (high and low) is done using macro which calls to a function. In addition, to calculate the offset of FRC, a simple macro is used. This code can be simplified by adding an helper function and calculating the offset explicitly instead of using an additional macro for that. Add the helper function and convert the existing code.

2022-07-25mlxsw: spectrum_ptp: Initialize the clock to zero as part of initializationAmit Cohen1-2/+1
As lately recommended in the mailing list[1], set the clock to zero time as part of initialization. The idea is that when the clock reads 'Jan 1, 1970', then it is clearly wrong and user will not mistakenly think that the clock is set correctly. If as part of initialization, the driver sets the clock, user might see correct date and time (maybe with a small shift) and assume that there is no need to sync the clock. Fix the existing code of Spectrum-1 to set the 'timecounter' to zero.

In Spectrum-2, all the packets are time stamped, the MTPCPC register is used to configure the types of packets that will adjust the correction field and which port will trap PTP packets. If ingress correction is set on a port for a given packet type, then when such a packet is received via the port, the current time stamp is subtracted from the correction field. If egress correction is set on a port for a given packet type, then when such a packet is transmitted via the port, the current time stamp is added to the correction field. Assuming the systems is configured correctly, the above means that the correction field will contain the transient delay between the ports.

On Versal TSU clock cannot be disabled irrespective of whether PTP is used. Hence introduce a new Versal config structure with a "need tsu" caps flag and check the same in runtime_suspend/resume before cutting off clocks. More information on this for future reference: This is an IP limitation on versions 1p11 and 1p12 when Qbv is enabled (See designcfg1, bit 3). However it is better to rely on an SoC specific check rather than the IP version because tsu clk property itself may not represent actual HW tsu clock on some chip designs.

macsec_add_txsa() init_rx_sa() allocates relevant resource for rx_sa->stats and rx_sa-> key.tfm with alloc_percpu() and macsec_alloc_tfm(). When some error occurs after init_rx_sa() is called in macsec_add_rxsa(), the function released rx_sa with kfree() without releasing rx_sa->stats and rx_sa-> key.tfm, which will lead to a resource leak. We should call macsec_rxsa_put() instead of kfree() to decrease the ref count of rx_sa and release the relevant resource if the refcount is 0. The same bug exists in macsec_add_txsa() for tx_sa as well. This patch fixes the above two bugs.

2022-07-25macsec: always read MACSEC_SA_ATTR_PN as a u64Sabrina Dubroca1-3/+3
Currently, MACSEC_SA_ATTR_PN is handled inconsistently, sometimes as a u32, sometimes forced into a u64 without checking the actual length of the attribute. Instead, we can use nla_get_u64 everywhere, which will read up to 64 bits into a u64, capped by the actual length of the attribute coming from userspace. This fixes several issues: - the check in validate_add_rxsa doesn't work with 32-bit attributes - the checks in validate_add_txsa and validate_upd_sa incorrectly reject X << 32 (with X != 0) Fixes: 48ef50fa866a ("macsec: Netlink support of XPN cipher suites (IEEE 802.1AEbw)") Signed-off-by: Sabrina Dubroca <[email protected]> Signed-off-by: David S.

To avoid leaving the existing macsec device in an inconsistent state if this test fails during changelink, reuse the cleanup mechanism introduced for HW offload. This wasn't needed until now because macsec_changelink_common could not fail during changelink, as modifying the cipher suite was not allowed.
