It is possible for a GSI channel's state to be changed as a result of an action by a different execution environment. Specifically, the modem is able to issue a GSI generic command that causes a state change on a GSI channel associated with the AP. A channel's state only needs to be known when a channel is allocated or deallocaed, started or stopped, or reset. So there is little value in caching the state anyway. Stop recording a copy of the channel's last known state, and instead fetch the true state from hardware whenever it's needed. In such cases, *do* record the state in a local variable, in case an error message reports it (so the value reported is the value seen). Signed-off-by:

Russell King says: ==================== net: dsa: mv88e6xxx: augment phylink support for 10G This series adds phylink 10G support for the 88E6390 series switches, as suggested by Andrew Lunn. The first patch cleans up the code to use generic definitions for the registers in a similar way to what was done with the initial conversion of 1G serdes support. The second patch adds the necessary bits 10GBASE mode to the pcs_get_state() method. ==================== Signed-off-by: -

The private MV88E6390_PCS_CONTROL_1 definitions in serdes.h reflects the IEEE 802.3 standard PCS control register 1 definitions, only offset by 0x1000 in the PHYXS register space. Rather than inventing our own, use those that already exist, and name the register MV88E6390_10G_CTRL1. Signed-off-by:

Igor Russkikh says: ==================== net: atlantic: A2 support This patchset adds support for the new generation of Atlantic NICs. Chip generations are mostly compatible register-wise, but there are still some differences. Therefore we've made some of first generation (A1) code non-static to re-use it where possible. Some pieces are A2 specific, in which case we redefine/extend such APIs. v2: * removed #pragma pack (2 structures require the packed attribute); * use defines instead of magic numbers where possible; v1: https://patchwork.ozlabs.org/cover/1276220/ ==================== Signed-off-by:

platform_get_resource() may fail and return NULL, so we should better check it's return value to avoid a NULL pointer dereference since devm_ioremap() does not check input parameters for null.

In skb_panic() the real pointer values are really needed to diagnose issues, e.g. data and head are related (to calculate headroom). The hashed versions of the addresses doesn't make much sense here. The patch use the printk specifier %px to print the actual address.

This patch changes the behavior of TCP_LINGER2 about its limit. The sysctl_tcp_fin_timeout used to be the limit of TCP_LINGER2 but now it's only the default value. A new macro named TCP_FIN_TIMEOUT_MAX is added as the limit of TCP_LINGER2, which is 2 minutes. Since TCP_LINGER2 used sysctl_tcp_fin_timeout as the default value and the limit in the past, the system administrator cannot set the default value for most of sockets and let some sockets have a greater timeout. It might be a mistake that let the sysctl to be the limit of the TCP_LINGER2. Maybe we can add a new sysctl to set the max of TCP_LINGER2, but FIN-WAIT-2 timeout is usually no need to be too long and 2 minutes are legal considering TCP specs. Changes in v3: - Remove the new socket option and change the TCP_LINGER2 behavior so that the timeout can be set to value between sysctl_tcp_fin_timeout and 2 minutes. Changes in v2: - Add int overflow check for the new socket option. Changes in v1: - Add a new socket option to set timeout greater than sysctl_tcp_fin_timeout. Signed-off-by:

Heiner Kallweit authored
Considering the few messages we have in the driver, there's not really a benefit in being able to control them on a message type level. Therefore simplify the code and switch to the netdev_xxx message functions. In addition add net_ratelimit() to messages that can be printed from a hot path. Signed-off-by:

The counter handling functions can only fail if rtl8169_do_counters() times out. In the poll function we emit an error message in case of timeout, therefore we don't have to propagate the timeout all the way up just to print another message basically saying the same. Signed-off-by:

Net core - __dev_set_promiscuity - prints a message already when promiscuous mode in entered/left, therefore we don't have to do this in the driver too. Also the driver message would be misleading (would be because "link" message level is disabled per default) because it would print "promisc mode enabled" even if it's being left. Reason is that __dev_change_flags() calls dev_set_rx_mode() before touching the promisc flag. Signed-off-by:

This is a nice feature, but has a drawback: no chapters can have the same sumber. So, we need to change two chapter titles, to avoid warnings when building the docs.
