2019-09-13rtlwifi: rtl8723be: Convert macros that set descriptorLarry Finger2-272/+470
As a first step in the conversion, the macros that set the RX and TX descriptors are converted to static inline routines, and the names are changed from upper to lower case. To minimize the changes in a given step, the input descriptor information is left as as a byte array (u8 *), even though it should be a little-endian word array (__le32 *). That will be changed in the next patch. Several places where checkpatch.pl complains about a space after a cast are fixed.

2019-09-13rtlwifi: rtl8723be: Replace local bit manipulation macrosLarry Finger1-75/+74
This driver uses a set of local macros to manipulate the RX and TX descriptors, which are all little-endian quantities. These macros are replaced by the bitfield macros le32p_replace_bits() and le32_get_bits(). In several places, the macros operated on an entire 32-bit word. In these cases, a direct read or replacement is used. Signed-off-by: Larry Finger <Larry.Finger@lwfinger.net> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

In this step, the read/write routines for the descriptors are converted to use __le32 quantities, thus a lot of casts can be removed. Callback routines still use the 8-bit arrays, but these are changed within the specified routine. The macro that cleared a descriptor has now been converted into an inline routine.

2019-09-11tcp: force a PSH flag on TSO packetsEric Dumazet1-2/+13
When tcp sends a TSO packet, adding a PSH flag on it reduces the sojourn time of GRO packet in GRO receivers. This is particularly the case under pressure, since RX queues receive packets for many concurrent flows. A sender can give a hint to GRO engines when it is appropriate to flush a super-packet, especially when pacing is in the picture, since next packet is probably delayed by one ms. Having less packets in GRO engine reduces chance of LRU eviction or inflated RTT, and reduces GRO cost. We found recently that we must not set the PSH flag on individual full-size MSS segments [1] : Under pressure (CWR state), we better let the packet sit for a small delay (depending on NAPI logic) so that the ACK packet is delayed, and thus next packet we send is also delayed a bit. Eventually the bottleneck queue can be drained. DCTCP flows with CWND=1 have demonstrated the issue. This patch allows to slowdown the aggregate traffic without involving high resolution timers on senders and/or receivers. It has been used at Google for about four years, and has been discussed at various networking conferences. [1] segments smaller than MSS already have PSH flag set by tcp_sendmsg() / tcp_mark_push(), unless MSG_MORE has been requested by the user.

2019-09-11ipv6: Don't use dst gateway directly in ip6_confirm_neigh()Stefano Brivio1-1/+1
This is the equivalent of commit 2c6b55f45d53 ("ipv6: fix neighbour resolution with raw socket") for ip6_confirm_neigh(): we can send a packet with MSG_CONFIRM on a raw socket for a connected route, so the gateway would be :: here, and we should pick the next hop using rt6_nexthop() instead. This was found by code review and, to the best of my knowledge, doesn't actually fix a practical issue: the destination address from the packet is not considered while confirming a neighbour, as ip6_confirm_neigh() calls choose_neigh_daddr() without passing the packet, so there are no similar issues as the one fixed by said commit. A possible source of issues with the existing implementation might come from the fact that, if we have a cached dst, we won't consider it, while rt6_nexthop() takes care of that. I might just not be creative enough to find a practical problem here: the only way to affect this with cached routes is to have one coming from an ICMPv6 redirect, but if the next hop is a directly connected host, there should be no topology for which a redirect applies here, and tests with redirected routes show no differences for MSG_CONFIRM (and MSG_PROBE) packets on raw sockets destined to a directly connected host. However, directly using the dst gateway here is not consistent anymore with neighbour resolution, and, in general, as we want the next hop, using rt6_nexthop() looks like the only sane way to fetch it.

2019-09-11net: stmmac: implement support for passive mode converters via dtAlexandru Ardelean3-2/+35
In-between the MAC & PHY there can be a mode converter, which converts one mode to another (e.g. GMII-to-RGMII). The converter, can be passive (i.e. no driver or OS/SW information required), so the MAC & PHY need to be configured differently. For the `stmmac` driver, this is implemented via a `mac-mode` property in the device-tree, which configures the MAC into a certain mode, and for the PHY a `phy_interface` field will hold the mode of the PHY. The mode of the PHY will be passed to the PHY and from there-on it work in a different mode. If unspecified, the default `phy-mode` will be used for both.

Currently frame registrations are not purged, even when changing the interface type. This can lead to potentially weird situations where frames possibly not allowed on a given interface type remain registered due to the type switching happening after registration. The kernel currently relies on userspace apps to actually purge the registrations themselves, this is not something that the kernel should rely on.

commit 1222a1601488 ("nl80211: Fix possible Spectre-v1 for CQM RSSI thresholds") was incomplete and requires one more fix to prevent accessing to rssi_thresholds[n] because user can control rssi_thresholds[i] values to make i reach to n. For example, rssi_thresholds = {-400, -300, -200, -100} when last is -34.

With the help of boolinit.cocci, we use !nl80211_reg_change_event_fill instead of (nl80211_reg_change_event_fill == false). Meanwhile, Clean up the code.
