The PHY performs just as well when left in its default configuration and it makes senses because this poke gets reset just after init. According to the documentation, all registers in the Analog/DSP bank are reset when there is a mode switch from 10BT to 100BT. The bank is also reset on power down and soft reset, so we will never see the value which may have been set by the bootloader. In the end, we have used the default configuration so far and there is no reason to change now. Remove CONFIG_A6 poke to make this clear. Reviewed-by:

The timer mode register now has a separate field for the reload value. Since we always use this timer with the reload (for interrupt moderation) we set this to the same as the initial value. Previous hardware ignores this field, so we can safely set these bits on all hardware that uses this register. Signed-off-by:

Daniel Borkmann says: ==================== pull-request: bpf-next 2017-12-18 The following pull-request contains BPF updates for your *net-next* tree. The main changes are: 1) Allow arbitrary function calls from one BPF function to another BPF function. As of today when writing BPF programs, __always_inline had to be used in the BPF C programs for all functions, unnecessarily causing LLVM to inflate code size. Handle this more naturally with support for BPF to BPF calls such that this __always_inline restriction can be overcome. As a result, it allows for better optimized code and finally enables to introduce core BPF libraries in the future that can be reused out of different projects. x86 and arm64 JIT support was added as well, from Alexei. 2) Add infrastructure for tagging functions as error injectable and allow for BPF to return arbitrary error values when BPF is attached via kprobes on those. This way of injecting errors generically eases testing and debugging without having to recompile or restart the kernel. Tags for opting-in for this facility are added with BPF_ALLOW_ERROR_INJECTION(), from Josef. 3) For BPF offload via nfp JIT, add support for bpf_xdp_adjust_head() helper call for XDP programs. First part of this work adds handling of BPF capabilities included in the firmware, and the later patches add support to the nfp verifier part and JIT as well as some small optimizations, from Jakub. 4) The bpftool now also gets support for basic cgroup BPF operations such as attaching, detaching and listing current BPF programs. As a requirement for the attach part, bpftool can now also load object files through 'bpftool prog load'. This reuses libbpf which we have in the kernel tree as well. bpftool-cgroup man page is added along with it, from Roman. 5) Back then commit e87c6bc3 ("bpf: permit multiple bpf attachments for a single perf event") added support for attaching multiple BPF programs to a single perf event. Given they are configured through perf's ioctl() interface, the interface has been extended with a PERF_EVENT_IOC_QUERY_BPF command in this work in order to return an array of one or multiple BPF prog ids that are currently attached, from Yonghong. 6) Various minor fixes and cleanups to the bpftool's Makefile as well as a new 'uninstall' and 'doc-uninstall' target for removing bpftool itself or prior installed documentation related to it, from Quentin. 7) Add CONFIG_CGROUP_BPF=y to the BPF kernel selftest config file which is required for the test_dev_cgroup test case to run, from Naresh. 8) Fix reporting of XDP prog_flags for nfp driver, from Jakub. 9) Fix libbpf's exit code from the Makefile when libelf was not found in the system, also from Jakub. ==================== Signed-off-by:

Alexei Starovoitov says: ==================== First of all huge thank you to Daniel, John, Jakub, Edward and others who reviewed multiple iterations of this patch set over the last many months and to Dave and others who gave critical feedback during netconf/netdev. The patch is solid enough and we thought through numerous corner cases, but it's not the end. More followups with code reorg and features to follow. TLDR: Allow arbitrary function calls from bpf function to another bpf function. Since the beginning of bpf all bpf programs were represented as a single function and program authors were forced to use always_inline for all functions in their C code. That was causing llvm to unnecessary inflate the code size and forcing developers to move code to header files with little code reuse. With a bit of additional complexity teach verifier to recognize arbitrary function calls from one bpf function to another as long as all of functions are presented to the verifier as a single bpf program. Extended program layout: .. r1 = .. // arg1 r2 = .. // arg2 call pc+1 // function call pc-relative exit .. = r1 // access arg1 .. = r2 // access arg2 .. call pc+20 // second level of function call ... It allows for better optimized code and finally allows to introduce the core bpf libraries that can be reused in different projects, since programs are no longer limited by single elf file. With function calls bpf can be compiled into multiple .o files. This patch is the first step. It detects programs that contain multiple functions and checks that calls between them are valid. It splits the sequence of bpf instructions (one program) into a set of bpf functions that call each other. Calls to only known functions are allowed. Since all functions are presented to the verifier at once conceptually it is 'static linking'. Future plans: - introduce BPF_PROG_TYPE_LIBRARY and allow a set of bpf functions to be loaded into the kernel that can be later linked to other programs with concrete program types. Aka 'dynamic linking'. - introduce function pointer type and indirect calls to allow bpf functions call other dynamically loaded bpf functions while the caller bpf function is already executing. Aka 'runtime linking'. This will be more generic and more flexible alternative to bpf_tail_calls. FAQ: Q: Interpreter and JIT changes mean that new instruction is introduced ? A: No. The call instruction technically stays the same. Now it can call both kernel helpers and other bpf functions. Calling convention stays the same as well. From uapi point of view the call insn got new 'relocation' BPF_PSEUDO_CALL similar to BPF_PSEUDO_MAP_FD 'relocation' of bpf_ldimm64 insn. Q: What had to change on LLVM side? A: Trivial LLVM patch to allow calls was applied to upcoming 6.0 release: https://reviews.llvm.org/rL318614 with few bugfixes as well. Make sure to build the latest llvm to have bpf_call support.

similar to x64 add support for bpf-to-bpf calls. When program has calls to in-kernel helpers the target call offset is known at JIT time and arm64 architecture needs 2 passes. With bpf-to-bpf calls the dynamically allocated function start is unknown until all functions of the program are JITed. Therefore (just like x64) arm64 JIT needs one extra pass over the program to emit correct call offsets. Implementation detail: Avoid being too clever in 64-bit immediate moves and always use 4 instructions (instead of 3-4 depending on the address) to make sure only one extra pass is needed. If some future optimization would make it worth while to optimize 'call 64-bit imm' further, the JIT would need to do 4 passes over the program instead of 3 as in this patch. For typical bpf program address the mov needs 3 or 4 insns, so unconditional 4 insns to save extra pass is a worthy trade off at this state of JIT. Signed-off-by:

Typical JIT does several passes over bpf instructions to compute total size and relative offsets of jumps and calls. With multitple bpf functions calling each other all relative calls will have invalid offsets intially therefore we need to additional last pass over the program to emit calls with correct offsets. For example in case of three bpf functions: main: call foo call bpf_map_lookup exit foo: call bar exit bar: exit We will call bpf_int_jit_compile() indepedently for main(), foo() and bar() x64 JIT typically does 4-5 passes to converge. After these initial passes the image for these 3 functions will be good except call targets, since start addresses of foo() and bar() are unknown when we were JITing main() (note that call bpf_map_lookup will be resolved properly during initial passes). Once start addresses of 3 functions are known we patch call_insn->imm to point to right functions and call bpf_int_jit_compile() again which needs only one pass. Additional safety checks are done to make sure this last pass doesn't produce image that is larger or smaller than previous pass. When constant blinding is on it's applied to all functions at the first pass, since doing it once again at the last pass can change size of the JITed code. Tested on x64 and arm64 hw with JIT on/off, blinding on/off. x64 jits bpf-to-bpf calls correctly while arm64 falls back to interpreter. All other JITs that support normal BPF_CALL will behave the same way since bpf-to-bpf call is equivalent to bpf-to-kernel call from JITs point of view. Signed-off-by:

global bpf_jit_enable variable is tested multiple times in JITs, blinding and verifier core. The malicious root can try to toggle it while loading the programs. This race condition was accounted for and there should be no issues, but it's safer to avoid this race condition. Signed-off-by:

though bpf_call is still the same call instruction and calling convention 'bpf to bpf' and 'bpf to helper' is the same the interpreter has to oparate on 'struct bpf_insn *'. To distinguish these two cases add a kernel internal opcode and mark call insns with it. This opcode is seen by interpreter only. JITs will never see it. Also add tiny bit of debug code to aid interpreter debugging. Signed-off-by:

adjust two tests, since verifier got smarter and add new one to test stack_zero logic Signed-off-by:
-
Alexei Starovoitov authored
programs with function calls are often passing various pointers via stack. When all calls are inlined llvm flattens stack accesses and optimizes away extra branches. When functions are not inlined it becomes the job of the verifier to recognize zero initialized stack to avoid exploring paths that program will not take. The following program would fail otherwise: ptr = &buffer_on_stack; *ptr = 0; ... func_call(.., ptr, ...) { if (..) *ptr = bpf_map_lookup(); } ... if (*ptr != 0) { // Access (*ptr)->field is valid. // Without stack_zero tracking such (*ptr)->field access // will be rejected } since stack slots are no longer uniform invalid | spill | misc add liveness marking to all slots, but do it in 8 byte chunks. So if nothing was read or written in [fp-16, fp-9] range it will be marked as LIVE_NONE. If any byte in that range was read, it will be marked LIVE_READ and stacksafe() check will perform byte-by-byte verification. If all bytes in the range were written the slot will be marked as LIVE_WRITTEN. This significantly speeds up state equality comparison and reduces total number of states processed. before after bpf_lb-DLB_L3.o 2051 2003 bpf_lb-DLB_L4.o 3287 3164 bpf_lb-DUNKNOWN.o 1080 1080 bpf_lxc-DDROP_ALL.o 24980 12361 bpf_lxc-DUNKNOWN.o 34308 16605 bpf_netdev.o 15404 10962 bpf_overlay.o 7191 6679 Signed-off-by: -

Allow arbitrary function calls from bpf function to another bpf function. To recognize such set of bpf functions the verifier does: 1. runs control flow analysis to detect function boundaries 2. proceeds with verification of all functions starting from main(root) function It recognizes that the stack of the caller can be accessed by the callee (if the caller passed a pointer to its stack to the callee) and the callee can store map_value and other pointers into the stack of the caller. 3. keeps track of the stack_depth of each function to make sure that total stack depth is still less than 512 bytes 4. disallows pointers to the callee stack to be stored into the caller stack, since they will be invalid as soon as the callee returns 5. to reuse all of the existing state_pruning logic each function call is considered to be independent call from the verifier point of view. The verifier pretends to inline all function calls it sees are being called. It stores the callsite instruction index as part of the state to make sure that two calls to the same callee from two different places in the caller will be different from state pruning point of view 6. more safety checks are added to liveness analysis Implementation details: . struct bpf_verifier_state is now consists of all stack frames that led to this function . struct bpf_func_state represent one stack frame. It consists of registers in the given frame and its stack . propagate_liveness() logic had a premature optimization where mark_reg_read() and mark_stack_slot_read() were manually inlined with loop iterating over parents for each register or stack slot. Undo this optimization to reuse more complex mark_*_read() logic . skip_callee() logic is not necessary from safety point of view, but without it mark_*_read() markings become too conservative, since after returning from the funciton call a read of r6-r9 will incorrectly propagate the read marks into callee causing inefficient pruning later . mark_*_read() logic is now aware of control flow which makes it more complex. In the future the plan is to rewrite liveness to be hierarchical. So that liveness can be done within basic block only and control flow will be responsible for propagation of liveness information along cfg and between calls. . tail_calls and ld_abs insns are not allowed in the programs with bpf-to-bpf calls . returning stack pointers to the caller or storing them into stack frame of the caller is not allowed Testing: . no difference in cilium processed_insn numbers . large number of tests follows in next patches Signed-off-by:

In the future the verifier may allow calls to unresolved functions and will do dynamic linking. This logic supports statically linked bpf functions only. Such function boundary detection could have been done as part of control flow graph building in check_cfg(), but it's cleaner to separate function boundary detection vs control flow checks within a subprogram (function) into logically indepedent steps. Follow up patches may split check_cfg() further, but not check_subprogs(). Only allow bpf-to-bpf calls for root only and for non-hw-offloaded programs. These restrictions can be relaxed in the future. Signed-off-by:

This reverts commits 5c9d2d5c, c7da82b8, and e7fe7b5c. We'll probably need to revisit this, but basically we should not complicate the get_user_pages_fast() case, and checking the actual page table protection key bits will require more care anyway, since the protection keys depend on the exact state of the VM in question. Particularly when doing a "remote" page lookup (ie in somebody elses VM, not your own), you need to be much more careful than this was. Dave Hansen says: "So, the underlying bug here is that we now a get_user_pages_remote() and then go ahead and do the p*_access_permitted() checks against the current PKRU. This was introduced recently with the addition of the new p??_access_permitted() calls. We have checks in the VMA path for the "remote" gups and we avoid consulting PKRU for them. This got missed in the pkeys selftests because I did a ptrace read, but not a *write*. I also didn't explicitly test it against something where a COW needed to be done" It's also not entirely clear that it makes sense to check the protection key bits at this level at all. But one possible eventual solution is to make the get_user_pages_fast() case just abort if it sees protection key bits set, which makes us fall back to the regular get_user_pages() case, which then has a vma and can do the check there if we want to. We'll see. Somewhat related to this all: what we _do_ want to do some day is to check the PAGE_USER bit - it should obviously always be set for user pages, but it would be a good check to have back. Because we have no generic way to test for it, we lost it as part of moving over from the architecture-specific x86 GUP implementation to the generic one in commit e585513b ("x86/mm/gup: Switch GUP to the generic get_user_page_fast() implementation").
