Currently if the user sets an odd value for [tx|rx]-usecs we align the value because the hardware only understands ITR values in multiples of 2. This seems misleading because we are essentially telling the user that the ITR value is odd, when in fact we have changed it internally. Fix this by reporting that setting odd ITR values is not allowed. Also, while making changes to ice_set_rc_coalesce() I noticed a bit of code/error duplication. Make the necessary changes to remove the duplication. Signed-off-by:

Matteo Croce says: ==================== mvpp2: per-cpu buffers This patchset workarounds an PP2 HW limitation which prevents to use per-cpu rx buffers. The first patch is just a refactor to prepare for the second one. The second one allocates percpu buffers if the following conditions are met: - CPU number is less or equal 4 - no port is using jumbo frames If the following conditions are not met at load time, of jumbo frame is enabled later on, the shared allocation is reverted. ==================== Signed-off-by:

Every mvpp2 unit can use up to 8 buffers mapped by the BM (the HW buffer manager). The HW will place the frames in the buffer pool depending on the frame size: short (< 128 bytes), long (< 1664) or jumbo (up to 9856). As any unit can have up to 4 ports, the driver allocates only 2 pools, one for small and one long frames, and share them between ports. When the first port MTU is set higher than 1664 bytes, a third pool is allocated for jumbo frames. This shared allocation makes impossible to use percpu allocators, and creates contention between HW queues. If possible, i.e. if the number of possible CPU are less than 8 and jumbo frames are not used, switch to a new scheme: allocate 8 per-cpu pools for short and long frames and bind every pool to an RXQ. When the first port MTU is set higher than 1664 bytes, the allocation scheme is reverted to the old behaviour (3 shared pools), and when all ports MTU are lowered, the per-cpu buffers are allocated again.

Refactor mvpp2_bm_pool_create(), mvpp2_bm_pool_destroy() and mvpp2_bm_pools_init() so that they accept a struct device instead of a struct platform_device, as they just need platform_device->dev. Removing such dependency makes the BM code more reusable in context where we don't have a pointer to the platform_device. Signed-off-by:

Vivien said about this change that: Also no need to call devlink_port_unregister from within dsa_port_setup as this step is inconditionally handled by dsa_port_teardown on error. which is not really true. The devlink_port_unregister function _is_ being called unconditionally from within dsa_port_setup, but not for this port that just failed, just for the previous ones which were set up. ports_teardown: for (i = 0; i < port; i++) dsa_port_teardown(&ds->ports[i]); Initially I was tempted to fix this by extending the "for" loop to also cover the port that failed during setup. But this could have potentially unforeseen consequences unrelated to devlink_port or even other types of ports than user ports, which I can't really test for. For example, if for some reason devlink_port_register itself would fail, then unconditionally unregistering it in dsa_port_teardown would not be a smart idea. The list might go on. So just make dsa_port_setup undo the setup it had done upon failure, and let the for loop undo the work of setting up the previous ports, which are guaranteed to be brought up to a consistent state.

Vivien Didelot says: ==================== net: dsa: mv88e6xxx: centralize SERDES IRQ handling Following Marek's work on the abstraction of the SERDES lanes mapping, this series trades the .serdes_irq_setup and .serdes_irq_free callbacks for new .serdes_irq_mapping, .serdes_irq_enable and .serdes_irq_status operations. This has the benefit to limit the various SERDES implementations to simple register accesses only; centralize the IRQ handling and mutex locking logic; as well as reducing boilerplate in the driver. ==================== Signed-off-by:

Now the first step of all .serdes_power implementations is getting the lane mapping. Since we have an operation for that, call it in the wrapper and pass the lane down to the .serdes_power operation. This also allows to avoid querying the SERDES lane twice in mv88e6xxx_port_set_cmode. At the same time provide mv88e6xxx_serdes_power_{up,down} helpers and prefer up/down instead of on/off as in the documentation. Signed-off-by:

Because the mapping between a SERDES interface and its lane is static, we don't need to stick with negative error codes actually and we can simply return 0 if there is no lane, just like the IRQ mapping. This way we can keep a simple and intuitive API using unsigned lane numbers while simplifying the implementations with single return statements.

Pull x86 fixes from Thomas Gleixner: "A set of fixes for x86: - Fix the bogus detection of 32bit user mode for uretprobes which caused corruption of the user return address resulting in application crashes. In the uprobes handler in_ia32_syscall() is obviously always returning false on a 64bit kernel. Use user_64bit_mode() instead which works correctly. - Prevent large page splitting when ftrace flips RW/RO on the kernel text which caused iTLB performance issues. Ftrace wants to be converted to text_poke() which avoids the problem, but for now allow large page preservation in the static protections check when the change request spawns a full large page. - Prevent arch_dynirq_lower_bound() from returning 0 when the IOAPIC is configured via device tree. In the device tree case the GSI 1:1 mapping is meaningless therefore the lower bound which protects the GSI range on ACPI machines is irrelevant. Return the lower bound which the core hands to the function instead of blindly returning 0 which causes the core to allocate the invalid virtual interupt number 0 which in turn prevents all drivers from allocating and requesting an interrupt. - Remove the bogus initialization of LDR and DFR in the 32bit bigsmp APIC driver. That uses physical destination mode where LDR/DFR are ignored, but the initialization and the missing clear of LDR caused the APIC to be left in a inconsistent state on kexec/reboot. - Clear LDR when clearing the APIC registers so the APIC is in a well defined state. - Initialize variables proper in the find_trampoline_placement() code. - Silence GCC( build warning for the real mode part of the build" * 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/mm/cpa: Prevent large page split when ftrace flips RW on kernel text x86/build: Add -Wnoaddress-of-packed-member to REALMODE_CFLAGS, to silence GCC9 build warning x86/boot/compressed/64: Fix missing initialization in find_trampoline_placement() x86/apic: Include the LDR when clearing out APIC registers x86/apic: Do not initialize LDR and DFR for bigsmp uprobes/x86: Fix detection of 32-bit user mode x86/apic: Fix arch_dynirq_lower_bound() bug for DT enabled machines

Call to 'pci_free_irq_vectors()' are missing both in the error handling path of the probe function, and in the remove function. Add them. Fixes: 19971f5e ("enetc: add PTP clock driver") Signed-off-by:

This change enables the use of SW timestamping on the Raspberry Pi 4. bcmgenet's transmit function bcmgenet_xmit() implements software timestamping. However the SOF_TIMESTAMPING_TX_SOFTWARE capability was missing and only SOF_TIMESTAMPING_RX_SOFTWARE was announced. By using ethtool_ops bcmgenet_ethtool_ops() as get_ts_info(), the SOF_TIMESTAMPING_TX_SOFTWARE capability is announced. Similar to commit a8f5cb9e ("smsc95xx: use ethtool_op_get_ts_info()") Signed-off-by:

the following tdc test fails on Fedora: # ./tdc.py -e 2638 -- ns/SubPlugin.__init__ Test 2638: Add matchall and try to get it -----> prepare stage *** Could not execute: "$TC qdisc add dev $DEV1 clsact" -----> prepare stage *** Error message: "/bin/sh: ip: command not found" returncode 127; expected [0] -----> prepare stage *** Aborting test run. Let nsPlugin.py use the 'IP' variable introduced with commit 92c1a19e ("tc-tests: added path to ip command in tdc"), so that the path to 'ip' is correctly resolved to the value we have in tdc_config.py. # ./tdc.py -e 2638 -- ns/SubPlugin.__init__ Test 2638: Add matchall and try to get it All test results: 1..1 ok 1 2638 - Add matchall and try to get it Fixes: 489ce2f4 ("tc-testing: Restore original behaviour for namespaces in tdc") Reported-by:

Davide Caratti says: ==================== net: tls: add socket diag The current kernel does not provide any diagnostic tool, except getsockopt(TCP_ULP), to know more about TCP sockets that have an upper layer protocol (ULP) on top of them. This series extends the set of information exported by INET_DIAG_INFO, to include data that are specific to the ULP (and that might be meaningful for debug/testing purposes). patch 1/3 ensures that the control plane reads/updates ULP specific data using RCU. patch 2/3 extends INET_DIAG_INFO and allows knowing the ULP name for each TCP socket that has done setsockopt(TCP_ULP) successfully. patch 3/3 extends kTLS to let programs like 'ss' know the protocol version and the cipher in use. Changes since v2: - remove unneeded #ifdef and fix reverse christmas tree in tls_get_info(), thanks to Jakub Kicinski Changes since v1: - don't worry about grace period when accessing ulp_ops, thanks to Jakub Kicinski and Eric Dumazet - use rcu_dereference() to access ULP data in tls get_info(), and test against NULL value, thanks to Jakub Kicinski - move RCU protected section inside tls get_info(), thanks to Jakub Kicinski Changes since RFC: - some coding style fixes, thanks to Jakub Kicinski - add X_UNSPEC as lowest value of uAPI enums, thanks to Jakub Kicinski - fix assignment of struct nlattr *start, thanks to Jakub Kicinski - let tls dump RXCONF and TXCONF, suggested by Jakub Kicinski - don't dump anything if TLS version or cipher are 0 (but still return a constant size in get_aux_size()), thanks to Boris Pismenny - constify first argument of get_info() and get_size() - use RCU to access access ulp_ops, like it's done for ca_ops - add patch 1/3, from Jakub Kicinski ==================== Signed-off-by:
