Two recent commits added new RSI_FSM_STATES (namely FSM_FW_NOT_LOADED and FSM_COMMON_DEV_PARAMS_SENT) and the corresponding table fsm_state was not updated to match. This can lead to an array overrun when accessing the latter two states in fsm_state. Fix this by adding in the missing states.

Since commit 9cc4b7cb ("brcmfmac: Make skb header writable before use") the headroom usage has been fixed. However, the driver was keeping statistics that got lost.

When user adds a virtual interface driver will set the bss_type to the iface_type given by the user. When supplicant is started on the same interface, a call to change_virtual_intf will be triggered if if_type is not NL80211_IFTYPE_STATION. Here driver should not update it's bss_type, because bss_type is intended to indicate the original iface_type and changing the same will defeat the purpose of creating this interface. Signed-off-by:

The function brcmf_net_attach() can only fail when register_netdevice() fails. When this happens register_netdevice() calls priv_destructor, ie. brcmf_cfg80211_free_netdev() freeing the vif instance. Also upon this failure brcmf_net_attach() calls free_netdev(). However, callers are also doing cleanup resulting in double free. In some places they need netdev private space as it holds parameters to communicate with the device. So we want to do the cleanup only in callers of brcmf_net_attach() by making the following changes: - set priv_destructor after register_netdevice() succeeds. - remove call to free_netdev() in brcmf_net_attach(). - call free_netdev() in brcmf_net_detach() for unregistered netdev. - add free_netdev() if brcmf_net_attach() fails for a created interface. Fixes: cf124db5 ("net: Fix inconsistent teardown and release of private netdev state.") Reviewed-by:

What makes me happy that we have now more vendors actively contributing to upstream drivers. In this pull request we have patches from Broadcom, Intel, Qualcomm, Realtek and Redpine Signals, and I still have patches from Marvell and Quantenna pending in patchwork. Now that's something comparing to how things looked 11 years ago in Jeff Garzik's "State of the Union: Wireless" email: https://lkml.org/lkml/2006/1/5/671 Major changes: wil6210 * add low level RF sector interface via nl80211 vendor commands * add module parameter ftm_mode to load separate firmware for factory testing * support devices with different PCIe bar size * add support for PCIe D3hot in system suspend * remove ioctl interface which should not be in a wireless driver ath10k * go back to using dma_alloc_coherent() for firmware scratch memory * add per chain RSSI reporting brcmfmac * add support multi-scheduled scan * add scheduled scan support for specified BSSIDs * add support for brcm43430 revision 0 wlcore * add wil1285 compatible rsi * add RS9113 USB support iwlwifi * FW API documentation improvements (for tools and htmldoc) * continuing work for the new A000 family * bump the maximum supported FW API to 31 * improve the differentiation between 8000, 9000 and A000 families ==================== Signed-off-by:

Marcelo Ricardo Leitner says: ==================== sctp: RFC 4960 Errata fixes This patchset contains fixes for 4 Errata topics from https://tools.ietf.org/html/draft-ietf-tsvwg-rfc4960-errata-01 Namely, sections: 3.12. Order of Adjustments of partial_bytes_acked and cwnd 3.22. Increase of partial_bytes_acked in Congestion Avoidance 3.26. CWND Increase in Congestion Avoidance Phase 3.27. Refresh of cwnd and ssthresh after Idle Period Tests performed with netperf using net namespaces, with drop rates at 0%, 0.5% and 1% by netem, IPv4 and IPv6, 10 runs for each combination. I couldn't spot differences on the stats. With and without these patches the results vary in a similar way in terms of throughput and retransmissions. Tests with 20ms delay and 20ms delay + drops at 0.5% and 1% also had results in a similar way, no noticeable difference. Looking at cwnd, it was possible to notice slightly lower values being used while still sustaining same throughput profile. ==================== Signed-off-by:

RFC 4960 Errata 3.27 identifies that ssthresh should be adjusted to cwnd because otherwise it could cause the transport to lock into congestion avoidance phase specially if ssthresh was previously reduced by some packet drop, leading to poor performance. The Errata says to adjust ssthresh to cwnd only once, though the same goal is achieved by updating it every time we update cwnd too. The caveat is that we could take longer to get back up to speed but that should be compensated by the fact that we don't adjust on RTO basis (as RFC says) but based on Heartbeats, which are usually way longer.

RFC4960 Errata 3.26 identified that at the same time RFC4960 states that cwnd should never grow more than 1*MTU per RTT, Section 7.2.2 was underspecified and as described could allow increasing cwnd more than that. This patch updates it so partial_bytes_acked is maxed to cwnd if flight_size doesn't reach cwnd, protecting it from such case.

Marcelo Ricardo Leitner authored
As per RFC4960 Errata 3.22, this condition is not needed anymore as it could cause the partial_bytes_acked to not consider the TSNs acked in the Gap Ack Blocks although they were received by the peer successfully. This patch thus drops the check for new Cumulative TSN Ack Point, leaving just the flight_size < cwnd one.

Marcelo Ricardo Leitner authored
RFC4960 Errata 3.12 says RFC4960 is unclear about the order of adjustments applied to partial_bytes_acked and cwnd in the congestion avoidance phase, and that the actual order should be: partial_bytes_acked is reset to (partial_bytes_acked - cwnd). Next, cwnd is increased by MTU. We were first increasing cwnd, and then subtracting the new value pba, which leads to a different result as pba is smaller than what it should and could cause cwnd to not grow as much.

On ACPI systems, the driver depends on firmware pre-initializing the EMAC because we don't have access to the clocks, and the EMAC has specific clock programming requirements. Therefore, we don't want to reset the EMAC while we are completing the initialization. Tested-by:

Verify that the caller-provided sockaddr structure is large enough to contain the sa_family field, before accessing it in bind() and connect() handlers of the AF_IUCV socket. Since neither syscall enforces a minimum size of the corresponding memory region, very short sockaddrs (zero or one byte long) result in operating on uninitialized memory while referencing .sa_family.
