net: phy: micrel: Correct bit assignments for phy_device flags

2023-09-19T10:22:58+00:00

[ Upstream commit 719c5e37e99d2fd588d1c994284d17650a66354c ] Previously, the defines for phy_device flags in the Micrel driver were ambiguous in their representation. They were intended to be bit masks but were mistakenly defined as bit positions. This led to the following issues: - MICREL_KSZ8_P1_ERRATA, designated for KSZ88xx switches, overlapped with MICREL_PHY_FXEN and MICREL_PHY_50MHZ_CLK. - Due to this overlap, the code path for MICREL_PHY_FXEN, tailored for the KSZ8041 PHY, was not executed for KSZ88xx PHYs. - Similarly, the code associated with MICREL_PHY_50MHZ_CLK wasn't triggered for KSZ88xx. To rectify this, all three flags have now been explicitly converted to use the `BIT()` macro, ensuring they are defined as bit masks and preventing potential overlaps in the future.

ipv4: ignore dst hint for multipath routes

[ Upstream commit 6ac66cb03ae306c2e288a9be18226310529f5b25 ] Route hints when the nexthop is part of a multipath group causes packets in the same receive batch to be sent to the same nexthop irrespective of the multipath hash of the packet. So, do not extract route hint for packets whose destination is part of a multipath group. A new SKB flag IPSKB_MULTIPATH is introduced for this purpose, set the flag when route is looked up in ip_mkroute_input() and use it in ip_extract_route_hint() to check for the existence of the flag.

usb: typec: bus: verify partner exists in typec_altmode_attention

2023-09-19T10:22:53+00:00

commit f23643306430f86e2f413ee2b986e0773e79da31 upstream. Some usb hubs will negotiate DisplayPort Alt mode with the device but will then negotiate a data role swap after entering the alt mode. The data role swap causes the device to unregister all alt modes, however the usb hub will still send Attention messages even after failing to reregister the Alt Mode. type_altmode_attention currently does not verify whether or not a device's altmode partner exists, which results in a NULL pointer error when dereferencing the typec_altmode and typec_altmode_ops belonging to the altmode partner. Verify the presence of a device's altmode partner before sending the Attention message to the Alt Mode driver.
