2020-05-18net/mlx5: Move iseg access helper routines close to mlx5_core driverParav Pandit
Only mlx5_core driver handles fw initialization check and command interface revision check. Hence move them inside the mlx5_core driver where it is used. This avoid exposing these helpers to all mlx5 drivers. Signed-off-by: Parav Pandit <parav@mellanox.com> Signed-off-by: Saeed Mahameed <saeedm@mellanox.com>

2020-05-18mwifiex: Fix memory corruption in dump_stationPali Rohár
The mwifiex_cfg80211_dump_station() uses static variable for iterating over a linked list of all associated stations (when the driver is in UAP role). This has a race condition if .dump_station is called in parallel for multiple interfaces. This corruption can be triggered by registering multiple SSIDs and calling, in parallel for multiple interfaces iw dev <iface> station dump [16750.719775] Unable to handle kernel paging request at virtual address dead000000000110 ...

Seven years ago we tried to fix a leak but actually introduced a double free instead. It was an understandable mistake because the code was a bit confusing and the free was done in the wrong place. The "skb" pointer is freed in both _rtl_usb_tx_urb_setup() and _rtl_usb_transmit(). The free belongs _rtl_usb_transmit() instead of _rtl_usb_tx_urb_setup() and I've cleaned the code up a bit to hopefully make it more clear.

2020-05-18ACPI: EC: PM: Avoid flushing EC work when EC GPE is inactiveRafael J. Wysocki
Flushing the EC work while suspended to idle when the EC GPE status is not set causes some EC wakeup events (notably power button and lid ones) to be missed after a series of spurious wakeups on the Dell XPS13 9360 in my office. If that happens, the machine cannot be woken up from suspend-to-idle by the power button or lid status change and it needs to be woken up in some other way (eg. by a key press). Flushing the EC work only after successful dispatching the EC GPE, which means that its status has been set, avoids the issue, so change the code in question accordingly.

2020-05-17tpm: check event log version before reading final eventsLoïc Yhuel
This fixes the boot issues since 5.3 on several Dell models when the TPM is enabled. Depending on the exact grub binary, booting the kernel would freeze early, or just report an error parsing the final events log. We get an event log in the SHA-1 format, which doesn't have a tcg_efi_specid_event_head in the first event, and there is a final events table which doesn't match the crypto agile format. __calc_tpm2_event_size reads bad "count" and "efispecid->num_algs", and either fails, or loops long enough for the machine to be appear frozen. So we now only parse the final events table, which is per the spec always supposed to be in the crypto agile format, when we got a event log in this format.

2020-05-16net: ipa: do not clear interrupt in gsi_channel_start()Alex Elder
In gsi_channel_start() there is harmless-looking comment "Clear the channel's event ring interrupt in case it's pending". The intent was to avoid getting spurious interrupts when first bringing up a channel. However we now use channel stop/start to implement suspend and resume, and an interrupt pending at the time we resume is actually something we don't want to ignore. The very first time we bring up the channel we do not expect an interrupt to be pending, and even if it were, the effect would simply be to schedule NAPI on that channel, which would find nothing to do, which is not a problem. Stop clearing any pending IEOB interrupt in gsi_channel_start(). That leaves one caller of the trivial function gsi_isr_ieob_clear(). Get rid of that function and just open-code it in gsi_isr_ieob() instead. This fixes a problem where suspend/resume IPA v4.2 would get stuck when resuming after a suspend.

2020-05-16mlxsw: spectrum_trap: Store all trap data in one arrayIdo Schimmel
Each trap registered with devlink is mapped to one or more Rx listeners. These listeners allow the switch driver (e.g., mlxsw_spectrum) to register a function that is called when a packet is received (trapped) for a specific reason. Currently, three arrays are used to describe the mapping between the logical devlink traps and the Rx listeners.

2020-05-16net: dsa: mt7530: fix roaming from DSA user portsDENG Qingfang
When a client moves from a DSA user port to a software port in a bridge, it cannot reach any other clients that connected to the DSA user ports. That is because SA learning on the CPU port is disabled, so the switch ignores the client's frames from the CPU port and still thinks it is at the user port. Fix it by enabling SA learning on the CPU port. To prevent the switch from learning from flooding frames from the CPU port, set skb->offload_fwd_mark to 1 for unicast and broadcast frames, and let the switch flood them instead of trapping to the CPU port. Multicast frames still need to be trapped to the CPU port for snooping, so set the SA_DIS bit of the MTK tag to 1 when transmitting those frames to disable SA learning.

Add driver level bulking to the XDP_TX action. An array of frame descriptors is held for each Tx frame queue and populated accordingly when the action returned by the XDP program is XDP_TX. The frames will be actually enqueued only when the array is filled. At the end of the NAPI cycle a flush on the queued frames is performed in order to enqueue the remaining FDs.

2020-05-15net/mlx5e: Calculate SQ stop room in a robust wayMaxim Mikityanskiy
Currently, different formulas are used to estimate the space that may be taken by WQEs in the SQ during a single packet transmit. This space is called stop room, and it's checked in the end of packet transmit to find out if the next packet could overflow the SQ. If it could, the driver tells the kernel to stop sending next packets. Many factors affect the stop room: 1. Padding with NOPs to avoid WQEs spanning over page boundaries. 2. Enabled and disabled offloads (TLS, upcoming MPWQE). 3. The maximum size of a WQE. The padding is performed before every WQE if it doesn't fit the current page. The current formula assumes that only one padding will be required per packet, and it doesn't take into account that the WQEs posted during the transmission of a single packet might exceed the page size in very rare circumstances. For example, to hit this condition with 4096-byte pages, TLS offload will have to interrupt an almost-full MPWQE session, be in the resync flow and try to transmit a near to maximum amount of data. To avoid SQ overflows in such rare cases after MPWQE is added, this patch introduces a more robust formula to estimate the stop room. The new formula uses the fact that a WQE of size X will not require more than X-1 WQEBBs of padding. More exact estimations are possible, but they result in much more complex and error-prone code for little gain. Before this patch, the TLS stop room included space for both INNOVA and ConnectX TLS offloads that couldn't run at the same time anyway, so this patch accounts only for the active one.
