Merge tag 'rxrpc-rewrite-20160929' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs David Howells says: ==================== rxrpc: Fixes and adjustments This set of patches contains some fixes and adjustments: (1) Connections for exclusive calls are being reused because the check to work out whether to set RXRPC_CONN_DONT_REUSE is checking where the parameters will be copied to (but haven't yet). (2) Make Tx loss-injection go through the normal return, so the state gets set correctly for what the code thinks it has done. Note lost Tx packets in the tx_data trace rather than the skb tracepoint. (3) Activate channels according to the current state from within the channel_lock to avoid someone changing it on us. (4) Reduce the local endpoint's services list to a single pointer as we don't allow service AF_RXRPC sockets to share UDP ports with other AF_RXRPC sockets, so there can't be more than one element in the list. (5) Request more ACKs in slow-start mode to help monitor the state driving the window configuration. (6) Display the serial number of the packet being ACK'd rather than the ACK packet's own serial number in the congestion trace as this can be related to other entries in the trace. ==================== Signed-off-by: NDavid S.

Vivien Didelot says: ==================== net: dsa: mv88e6xxx: Global (1) cosmetics The Global (1) internal SMI device of Marvell switches is a set of registers providing support to different units for MAC addresses (ATU), VLANs (VTU), PHY polling (PPU), etc. Chips (like 88E6060) may use a different address for it, or have subtleties in the units (e.g. different number of databases, changing how registers must be accessed), making it hard to maintain properly. This patchset is a first step to polish the Global (1) support, with no functional changes though. Here's basically what it does: - add helpers to access Global1 registers (same for Global2) - remove a few family checks (VTU/STU FID registers) - s/mv88e6xxx_vtu_stu_entry/mv88e6xxx_vtu_entry/ - add a per-chip mv88e6xxx_ops structure of function pointers: struct mv88e6xxx_ops { int (*get_eeprom)(struct mv88e6xxx_chip *chip, struct ethtool_eeprom *eeprom, u8 *data); int (*set_eeprom)(struct mv88e6xxx_chip *chip, struct ethtool_eeprom *eeprom, u8 *data); int (*set_switch_mac)(struct mv88e6xxx_chip *chip, u8 *addr); int (*phy_read)(struct mv88e6xxx_chip *chip, int addr, int reg, u16 *val); int (*phy_write)(struct mv88e6xxx_chip *chip, int addr, int reg, u16 val); }; Future patchsets will add ATU/VTU ops, software reset, etc. ==================== Signed-off-by: NDavid S.

The mv88e6xxx_ops is used to describe how to access the chip registers. It can be through SMI (via an MDIO bus), or via another interface such as crafted remote management frames. The correct BUS operations structure is chosen at runtime, depending on the chip address and connectivity. We will need the mv88e6xxx_ops name for future chip-wide operation structure, thus rename mv88e6xxx_ops to more explicit mv88e6xxx_bus_ops.

The Global (1) internal SMI device is an extended set of registers containing ATU, PPU, VTU, STU, etc. It is present on every switches, usually at SMI address 0x1B. But old models such as 88E6060 access it at address 0xF, thus using REG_GLOBAL is erroneous. Add a global1_addr info member used by mv88e6xxx_g1_{read,write} and mv88e6xxx_g1_wait helpers in a new global1.c file. This patch finally removes _mv88e6xxx_reg_{read,write}, in favor on the appropriate helpers. No functional changes here.

Reduce the rxrpc_local::services list to just a pointer as we don't permit multiple service endpoints to bind to a single transport endpoints (this is excluded by rxrpc_lookup_local()). The reason we don't allow this is that if you send a request to an AFS filesystem service, it will try to talk back to your cache manager on the port you sent from (this is how file change notifications are handled). To prevent someone from stealing your CM callbacks, we don't let AF_RXRPC sockets share a UDP socket if at least one of them has a service bound. Signed-off-by: NDavid Howells <dhowells@redhat.com>

In rxrpc_activate_channels(), the connection cache state is checked outside of the lock, which means it can change whilst we're waking calls up, thereby changing whether or not we're allowed to wake calls up. Fix this by moving the check inside the locked region. The check to see if all the channels are currently busy can stay outside of the locked region. Whilst we're at it: (1) Split the locked section out into its own function so that we can call it from other places in a later patch. (2) Determine the mask of channels dependent on the state as we're going to add another state in a later patch that will restrict the number of simultaneous calls to 1 on a connection.

In rxrpc_send_data_packet() make the loss-injection path return through the same code as the transmission path so that the RTT determination is initiated and any future timer shuffling will be done, despite the packet having been binned. Whilst we're at it: (1) Add to the tx_data tracepoint an indication of whether or not we're retransmitting a data packet. (2) When we're deciding whether or not to request an ACK, rather than checking if we're in fast-retransmit mode check instead if we're retransmitting. (3) Don't invoke the lose_skb tracepoint when losing a Tx packet as we're not altering the sk_buff refcount nor are we just seeing it after getting it off the Tx list. (4) The rxrpc_skb_tx_lost note is then no longer used so remove it. (5) rxrpc_lose_skb() no longer needs to deal with rxrpc_skb_tx_lost. Signed-off-by: NDavid Howells <dhowells@redhat.com>

Exclusive connections are currently reusable (which they shouldn't be) because rxrpc_alloc_client_connection() checks the exclusive flag in the rxrpc_connection struct before it's initialised from the function parameters.

Timur Tabi says: ==================== Add basic ACPI support to the Qualcomm Technologies EMAC driver This patch series adds support to the EMAC driver for extracting addresses, interrupts, and some _DSDs (properties) from ACPI. The first two patches clean up the code, and the third patch adds ACPI-specific functionality. The first patch fixes a bug with handling the platform_device for the internal PHY. This phy is treated as a separate device in both DT and ACPI, but since the platform is not released automatically when the driver unloads, managed functions like devm_ioremap_resource cannot be used. The second patch replaces of_get_mac_address with its platform-independent equivalent device_get_mac_address. The third patch parses the ACPI tables to obtain the platform_device for the primary EMAC node ("QCOM8070") and the internal phy node ("QCOM8071"). ==================== Signed-off-by: NDavid S.

Add support for reading addresses, interrupts, and _DSD properties from ACPI tables, just like with device tree. The HID for the EMAC device itself is QCOM8070. The internal PHY is represented by a child node with a HID of QCOM8071. The EMAC also has some complex clock initialization requirements that are not represented by this patch.

Suppose you have a map array value that is something like this struct foo { unsigned iter; int array[SOME_CONSTANT]; }; You can easily insert this into an array, but you cannot modify the contents of foo->array[] after the fact. This is because we have no way to verify we won't go off the end of the array at verification time. This patch provides a start for this work. We accomplish this by keeping track of a minimum and maximum value a register could be while we're checking the code. Then at the time we try to do an access into a MAP_VALUE we verify that the maximum offset into that region is a valid access into that memory region. So in practice, code such as this unsigned index = 0; if (foo->iter >= SOME_CONSTANT) foo->iter = index; else index = foo->iter++; foo->array[index] = bar; would be allowed, as we can verify that index will always be between 0 and SOME_CONSTANT-1. If you wish to use signed values you'll have to have an extra check to make sure the index isn't less than 0, or do something like index %= SOME_CONSTANT.

由 Lawrence Brakmo 提交于
The current code changes txhash (flowlables) on every retransmitted SYN/ACK, but only after the 2nd retransmitted SYN and only after tcp_retries1 RTO retransmits. With this patch: 1) txhash is changed with every SYN retransmits 2) txhash is changed with every RTO. The result is that we can start re-routing around failed (or very congested paths) as soon as possible. Otherwise application health checks may fail and the connection may be terminated before we start to change txhash. v4: Removed sysctl, txhash is changed for all RTOs v3: Removed text saying default value of sysctl is 0 (it is 100) v2: Added sysctl documentation and cleaned code Tested with packetdrill tests Signed-off-by: NLawrence Brakmo <brakmo@fb.com> Signed-off-by: NDavid S.

This is old code for old hardware and it is not really accurate to claim this to be maintained anymore. Change the status to "Obsolete" to make it clearer that minor cleanup and other unnecessary changes from automated tools is not necessarily beneficial and has larger risk of breaking something without being quickly noticed due to lack of testing.

Firmware is running watchdog timer for tracking copy engine ring index and write index. Whenever both indices are stuck at same location for given duration, watchdog will be trigger to assert target. While updating copy engine destination ring write index, driver ensures that write index will not be same as read index by finding delta between these two indices (CE_RING_DELTA). HTT target to host copy engine (CE5) is special case where ring buffers will be reused and delta check is not applied while updating write index. In rare scenario, whenever CE5 ring is full, both indices will be referring same location and this is causing CE ring stuck issue as explained above. This issue is originally reported on IPQ4019 during long hour stress testing and during veriwave max clients testsuites. The same issue is also observed in other chips as well. Fix this by ensuring that write index is one less than read index which means that full ring is available for receiving data.
