sockmap sample program takes arguments from cmd line but it reads them in using offsets into the array. Because we want to add more arguments in the future lets do proper argument handling. Also refactor code to pull apart sock init and ping/pong test. This allows us to add new tests in the future.

Commit 111e6b45 ("selftests/bpf: make test_verifier run most programs") enables tools/testing/selftests/bpf/test_verifier unit cases to run via bpf_prog_test_run command. With the latest code base, test_verifier had one test case failure: ... #473/p check deducing bounds from const, 2 FAIL retval 1 != 0 0: (b7) r0 = 1 1: (75) if r0 s>= 0x1 goto pc+1 R0=inv1 R1=ctx(id=0,off=0,imm=0) R10=fp0,call_-1 2: (95) exit from 1 to 3: R0=inv1 R1=ctx(id=0,off=0,imm=0) R10=fp0,call_-1 3: (d5) if r0 s<= 0x1 goto pc+1 R0=inv1 R1=ctx(id=0,off=0,imm=0) R10=fp0,call_-1 4: (95) exit from 3 to 5: R0=inv1 R1=ctx(id=0,off=0,imm=0) R10=fp0,call_-1 5: (1f) r1 -= r0 6: (95) exit processed 7 insns (limit 131072), stack depth 0 ... The test case does not set return value in the test structure and hence the return value from the prog run is assumed to be 0. However, the actual return value is 1. As a result, the test failed.

In commit b471f2f1 ("bpf: implement MAP_GET_NEXT_KEY command for LPM_TRIE map"), the implemented MAP_GET_NEXT_KEY callback function is guarded with rcu read lock. In the function body, "kmalloc(size, GFP_USER | __GFP_NOWARN)" is used which may sleep and violate rcu read lock region requirements.

Fix bug that causes _absolute_ rtsym sizes of > 8 bytes (as per symbol table) to result in incorrect space used during a TLV-based debug dump. Detail: The size calculation stage calculates the correct size (size of the rtsym address field == 8), while the dump uses the size in the table to calculate the TLV size to reserve. Symbols with size <= 8 are handled OK due to aligning sizes to 8, but including any absolute symbol with listed size > 8 leads to an ENOSPC error during the dump.

Jakub Kicinski says: ==================== net: sched: add extack support for cls offloads I've dropped the tests from the series because test_offloads.py changes will conflict with bpf-next patches. I will send four more patches with tests once bpf-next is merged back, hopefully still making it into 4.16 :) v4: - rebase on top of Alex's changes. --- Quentin says: This series tries to improve user experience when eBPF hardware offload hits error paths at load time. In particular, it introduces netlink extended ack support in the nfp driver. To that aim, transmission of the pointer to the extack object is piped through the `change()` operation of the existing classifiers (patch 1 to 6). Then it is used for TC offload in the nfp driver (patch 8) and in netdevsim (patch 9, selftest in patch 10). Patch 7 adds a helper to handle extack messages in the core when TC offload is disabled on the net device. For completeness extack is propagated for classifiers other than cls_bpf, but it's up to the drivers to make use of it. ==================== Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Broadcom tags inserted by Broadcom switches put a 4 byte header after the MAC SA and before the EtherType, which may look like some sort of 0 length LLC/SNAP packet (tcpdump and wireshark do think that way). With ACS enabled in stmmac the packets were truncated to 8 bytes on reception, whereas clearing this bit allowed normal reception to occur. In order to make that possible, we need to pass a net_device argument to the different core_init() functions and we are dependent on the Broadcom tagger padding packets correctly (which it now does). To be as little invasive as possible, this is only done for gmac1000 when the network device is DSA-enabled (netdev_uses_dsa() returns true).

Commit ccfdec90 ("macsec: Add support for GCM-AES-256 cipher suite") changed a few values in the uapi headers for MACsec. Because of existing userspace implementations, we need to preserve the value of MACSEC_DEFAULT_CIPHER_ID. Not doing that resulted in wpa_supplicant segfaults when a secure channel was created using the default cipher. Thus, swap MACSEC_DEFAULT_CIPHER_{ID,ALT} back to their original values. Changing the maximum length of the MACSEC_SA_ATTR_KEY attribute is unnecessary, as the previous value (MACSEC_MAX_KEY_LEN, which was 128B) is large enough to carry 32-bytes keys. This patch reverts MACSEC_MAX_KEY_LEN to 128B and restores the old length check on MACSEC_SA_ATTR_KEY.

This patch introduces an alternative way of obtaining resources - via ACPI tables provided by firmware. Enabling coexistence with the DT support, in addition to the OF_*->device_*/fwnode_* API replacement, required following steps to be taken: * Add mvpp2_acpi_match table * Omit clock configuration and obtain tclk from the property - in ACPI world, the firmware is responsible for clock maintenance. * Disable comphy and syscon handling as they are not available for ACPI. * Modify way of obtaining interrupts - use newly introduced fwnode_irq_get() routine * Until proper MDIO bus and PHY handling with ACPI is established in the kernel, use only link interrupts feature in the driver. For the RGMII port it results in depending on GMAC settings done during firmware stage. * When booting with ACPI MVPP2_QDIST_MULTI_MODE is picked by default, as there is no need to keep any kind of the backward compatibility. Moreover, a memory region used by mvmdio driver is usually placed in the middle of the address space of the PP2 network controller. The MDIO base address is obtained without requesting memory region (by devm_ioremap() call) in mvmdio.c, later overlapping resources are requested by the network driver, which is responsible for avoiding a concurrent access. In case the MDIO memory region is declared in the ACPI, it can already appear as 'in-use' in the OS. Because it is overlapped by second region of the network controller, make sure it is released, before requesting it again. The care is taken by mvpp2 driver to avoid concurrent access to this memory region. Signed-off-by: NMarcin Wojtas <mw@semihalf.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

'port_count' field of the mvpp2 structure holds an overall amount of available ports, based on DT nodes status. In order to be prepared to support other HW description, obtain the value by incrementing it upon each successful port initialization. This allowed for simplifying port indexing in the controller's private array, whose size is now not dynamically allocated, but fixed to MVPP2_MAX_PORTS. This patch simplifies creating and filling list of enabled ports and is a part of the preparation for adding ACPI support in the mvpp2 driver.
