2021-06-10bus: ti-sysc: Fix am335x resume hang for usb otg moduleTony Lindgren1-3/+50
[ Upstream commit 4d7b324e231366ea772ab10df46be31273ca39af ] On am335x, suspend and resume only works once, and the system hangs if suspend is attempted again. However, turns out suspend and resume works fine multiple times if the USB OTG driver for musb controller is loaded. The issue is caused my the interconnect target module losing context during suspend, and it needs a restore on resume to be reconfigure again as debugged earlier by Dave Gerlach <d-gerlach@ti.com>. There are also other modules that need a restore on resume, like gpmc as noted by Dave. So let's add a common way to restore an interconnect target module based on a quirk flag. For now, let's enable the quirk for am335x otg only to fix the suspend and resume issue. As gpmc is not causing hangs based on tests with BeagleBone, let's patch gpmc separately. For gpmc, we also need a hardware reset done before restore according to Dave. To reinit the modules, we decouple system suspend from PM runtime. We replace calls to pm_runtime_force_suspend() and pm_runtime_force_resume() with direct calls to internal functions and rely on the driver internal state. There no point trying to handle complex system suspend and resume quirks via PM runtime. This is issue should have already been noticed with commit 1819ef2e2d12 ("bus: ti-sysc: Use swsup quirks also for am335x musb") when quirk handling was added for am335x otg for swsup. But the issue went unnoticed as having musb driver loaded hides the issue, and suspend and resume works once without the driver loaded.

2021-06-10optee: use export_uuid() to copy client UUIDJens Wiklander2-4/+8
[ Upstream commit 673c7aa2436bfc857b92417f3e590a297c586dde ] Prior to this patch optee_open_session() was making assumptions about the internal format of uuid_t by casting a memory location in a parameter struct to uuid_t *. Fix this using export_uuid() to get a well defined binary representation and also add an octets field in struct optee_msg_param in order to avoid casting.

2021-06-10ice: Allow all LLDP packets from PF to TxDave Ertman1-1/+4
[ Upstream commit f9f83202b7263ac371d616d6894a2c9ed79158ef ] Currently in the ice driver, the check whether to allow a LLDP packet to egress the interface from the PF_VSI is being based on the SKB's priority field. It checks to see if the packets priority is equal to TC_PRIO_CONTROL. Injected LLDP packets do not always meet this condition. SCAPY defaults to a sk_buff->protocol value of ETH_P_ALL (0x0003) and does not set the priority field. There will be other injection methods (even ones used by end users) that will not correctly configure the socket so that SKB fields are correctly populated. Then ethernet header has to have to correct value for the protocol though. Add a check to also allow packets whose ethhdr->h_proto matches ETH_P_LLDP (0x88CC).

However when we build in-capsule send wr sge, we iterate without taking into account that the sgl may be chained and still fit in-capsule (which can happen if the sgl is bigger than 2, but lower-equal to 4).

[ Upstream commit 9453d45ecb6c2199d72e73c993e9d98677a2801b ] Function skb_ext_add() doesn't initialize created skb extension with any value and leaves it up to the user. However, since extension of type TC_SKB_EXT originally contained only single value tc_skb_ext->chain its users used to just assign the chain value without setting whole extension memory to zero first. This assumption changed when TC_SKB_EXT extension was extended with additional fields but not all users were updated to initialize the new fields which leads to use of uninitialized memory afterwards.
