| * net: filter: split filter.h and expose eBPF to user spaceAlexei Starovoitov2014-09-093-55/+67
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | allow user space to generate eBPF programs uapi/linux/bpf.h: eBPF instruction set definition linux/filter.h: the rest This patch only moves macro definitions, but practically it freezes existing eBPF instruction set, though new instructions can still be added in the future.

| * net: filter: add "load 64-bit immediate" eBPF instructionAlexei Starovoitov2014-09-095-1/+68
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | add BPF_LD_IMM64 instruction to load 64-bit immediate value into a register. All previous instructions were 8-byte. This is first 16-byte instruction. Two consecutive 'struct bpf_insn' blocks are interpreted as single instruction: insn[0].code = BPF_LD | BPF_DW | BPF_IMM insn[0].dst_reg = destination register insn[0].imm = lower 32-bit insn[1].code = 0 insn[1].imm = upper 32-bit All unused fields must be zero. Classic BPF has similar instruction: BPF_LD | BPF_W | BPF_IMM which loads 32-bit immediate value into a register. x64 JITs it as single 'movabsq %rax, imm64' arm64 may JIT as sequence of four 'movk x0, #imm16, lsl #shift' insn Note that old eBPF programs are binary compatible with new interpreter. It helps eBPF programs load 64-bit constant into a register with one instruction instead of using two registers and 4 instructions: BPF_MOV32_IMM(R1, imm32) BPF_ALU64_IMM(BPF_LSH, R1, 32) BPF_MOV32_IMM(R2, imm32) BPF_ALU64_REG(BPF_OR, R1, R2) User space generated programs will use this instruction to load constants only. To tell kernel that user space needs a pointer the _pseudo_ variant of this instruction may be added later, which will use extra bits of encoding to indicate what type of pointer user space is asking kernel to provide. For example 'off' or 'src_reg' fields can be used for such purpose. src_reg = 1 could mean that user space is asking kernel to validate and load in-kernel map pointer. src_reg = 2 could mean that user space needs readonly data section pointer src_reg = 3 could mean that user space needs a pointer to per-cpu local data All such future pseudo instructions will not be carrying the actual pointer as part of the instruction, but rather will be treated as a request to kernel to provide one. The kernel will verify the request_for_a_pointer, then will drop _pseudo_ marking and will store actual internal pointer inside the instruction, so the end result is the interpreter and JITs never see pseudo BPF_LD_IMM64 insns and only operate on generic BPF_LD_IMM64 that loads 64-bit immediate into a register. User space never operates on direct pointers and verifier can easily recognize request_for_pointer vs other instructions. Signed-off-by: Alexei Starovoitov <ast@plumgrid.com> Signed-off-by: David S.

For the mac80211 bits, Johannes says: "Not that much content this time. Some RCU cleanups, crypto performance improvements, and various patches all over, rather than listing them one might as well look into the git log instead." For the Bluetooth bits, Gustavo says: "The changes consists of: - Coding style fixes to HCI drivers - Corrupted ack value fix for the H5 HCI driver - A couple of Enhanced L2CAP fixes - Conversion of SMP code to use common L2CAP channel API - Page scan optimizations when using the kernel-side whitelist - Various mac802154 and and ieee802154 6lowpan cleanups - One new Atheros USB ID" For the iwlwifi bits, Emmanuel says: "We have a new big thing coming up which is called Dynamic Queue Allocation (or DQA). This is a completely new way to work with the Tx queues and it requires major refactoring. This is being done by Johannes and Avri. Besides this, Johannes disables U-APSD by default because of APs that would disable A-MPDU if the association supports U-ASPD. Luca contributed to the power area which he was cleaning up on the way while working on CSA. A few more random things here and there." For the Atheros bits, Kalle says: "For ath6kl we had two small fixes and a new SDIO device id. For ath10k the bigger changes are: * support for new firmware version 10.2 (Michal) * spectral scan support (Simon, Sven & Mathias) * export a firmware crash dump file (Ben & me) * cleaning up of pci.c (Michal) * print pci id in all messages, which causes most of the churn (Michal)" Beyond that, we have the usual collection of various updates to ath9k, b43, mwifiex, and wil6210, as well as a few other bits here and there.

In order to do this, we need to store the BSSID as it will have been cleared by mac80211 by the time we get notified of the disassociation. Also pass it around as an override to the various functions needing it, and keep taking it from the mac80211 data otherwise. This avoids having to keep track of the BSSID in all modes.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If we're manually testing the CT kill functionality via debugfs, we shouldn't schedule the work to recheck the temperature after the ct_kill_duration period has passed.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since we can't read the actual temperature when the firmware is running, just set the temperature to 0 when the test is disabled and disable CT Kill if it was enabled. Additionally, since we rely on iwl_mvm_tt_handler() to exit CT kill when in test mode, call iwl_mvm_exit_ctkill() in that function if the temperature is low again. Also make the iwl_mvm_enter_ctkill() and iwl_mvm_exit_ctkill() return if called when not necessary anymore (e.g. when iwl_mvm_exit_ctkill() is called when we're not in CT-kill).

However, some tests require the explicit usage of ps-poll. Allow setting use_ps_poll power option (through debugfs) to configure the ucode to use ps-poll instead. The ucode configuration is done by setting the advanced-pm flag while setting all the ACs to non-upasd mode.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This allows to leave a frame in the Tx Fifo which allows the firmware to try to enter burst mode. The end result of this is a better latency since the firmware utilises the TxOP better. Also limit the AMPDU size to the limit set in the ADDBA response. This doesn't change much since the AMPDU size was limited by the configuration of the hardware scheduler, but here we add a software limit by the mean of the link quality command.
