2020-04-26firmware_loader: revert removal of the fw_fallback_config exportLuis Chamberlain1-0/+1
Christoph's patch removed two unsused exported symbols, however, one symbol is used by the firmware_loader itself. If CONFIG_FW_LOADER=m so the firmware_loader is modular but CONFIG_FW_LOADER_USER_HELPER=y we fail the build at mostpost. ERROR: modpost: "fw_fallback_config" [drivers/base/firmware_loader/firmware_class.ko] undefined! This happens because the variable fw_fallback_config is built into the kernel if CONFIG_FW_LOADER_USER_HELPER=y always, so we need to grant access to the firmware loader module by exporting it.

Reorder include paths to ensure that runqslower sources are picking up vmlinux.h, generated by runqslower's own Makefile. When runqslower is built from selftests/bpf, due to current -I$(BPF_INCLUDE) -I$(OUTPUT) ordering, it might pick up not-yet-complete vmlinux.h, generated by selftests Makefile, which could lead to compilation errors like [0]. So ensure that -I$(OUTPUT) goes first and rely on runqslower's Makefile own dependency chain to ensure vmlinux.h is properly completed before source code relying on it is compiled.

2020-04-25bpf: Propagate expected_attach_type when verifying freplace programsToke Høiland-Jørgensen1-0/+8
For some program types, the verifier relies on the expected_attach_type of the program being verified in the verification process. However, for freplace programs, the attach type was not propagated along with the verifier ops, so the expected_attach_type would always be zero for freplace programs. This in turn caused the verifier to sometimes make the wrong call for freplace programs. For all existing uses of expected_attach_type for this purpose, the result of this was only false negatives (i.e., freplace functions would be rejected by the verifier even though they were valid programs for the target they were replacing). However, should a false positive be introduced, this can lead to out-of-bounds accesses and/or crashes. The fix introduced in this patch is to propagate the expected_attach_type to the freplace program during verification, and reset it after that is done.

2020-04-25bpf, x86_32: Fix clobbering of dst for BPF_JSETLuke Nelson1-4/+18
The current JIT clobbers the destination register for BPF_JSET BPF_X and BPF_K by using "and" and "or" instructions. This is fine when the destination register is a temporary loaded from a register stored on the stack but not otherwise. This patch fixes the problem (for both BPF_K and BPF_X) by always loading the destination register into temporaries since BPF_JSET should not modify the destination register. This bug may not be currently triggerable as BPF_REG_AX is the only register not stored on the stack and the verifier uses it in a limited way.

2020-04-25bpf, x86_32: Fix incorrect encoding in BPF_LDX zero-extensionLuke Nelson1-1/+3
The current JIT uses the following sequence to zero-extend into the upper 32 bits of the destination register for BPF_LDX BPF_{B,H,W}, when the destination register is not on the stack: EMIT3(0xC7, add_1reg(0xC0, dst_hi), 0); The problem is that C7 /0 encodes a MOV instruction that requires a 4-byte immediate; the current code emits only 1 byte of the immediate. This means that the first 3 bytes of the next instruction will be treated as the rest of the immediate, breaking the stream of instructions. This patch fixes the problem by instead emitting "xor dst_hi,dst_hi" to clear the upper 32 bits. This fixes the problem and is more efficient than using MOV to load a zero immediate. This bug may not be currently triggerable as BPF_REG_AX is the only register not stored on the stack and the verifier uses it in a limited way, and the verifier implements a zero-extension optimization. But the JIT should avoid emitting incorrect encodings regardless.

The driver is designed to drop Rx packets and reclaim the buffers when an allocation fails, and the network interface needs to safely handle this packet loss. Therefore, an allocation failure of Rx SKBs is relatively benign. However, the output of the warning message occurs with a high scheduling priority that can cause excessive jitter/latency for other high priority processing.

When a macsec interface is created, the mtu is calculated with the lower interface's mtu value. If the mtu of lower interface is lower than the length, which is needed by macsec interface, macsec's mtu value will be overflowed. So, if the lower interface's mtu is too low, macsec interface's mtu should be set to 0.

2020-04-25dt-bindings: phy: qcom-qusb2: Fix defaultsDouglas Anderson1-3/+3
The defaults listed in the bindings don't match what the code is actually doing. Presumably existing users care more about keeping existing behavior the same, so change the bindings to match the code in Linux. The "qcom,preemphasis-level" default has been wrong for quite a long time (May 2018). The other two were recently added. As some evidence that these values are wrong, this is from the Linux driver: - qcom,preemphasis-level: sets "PORT_TUNE1", lower 2 bits. Driver programs PORT_TUNE1 to 0x30 by default and (0x30 & 0x3) = 0. - qcom,bias-ctrl-value: sets "PLL_BIAS_CONTROL_2", lower 6 bits. Driver programs PLL_BIAS_CONTROL_2 to 0x20 by default and (0x20 & 0x3f) = 0x20 = 32. - qcom,hsdisc-trim-value: sets "PORT_TUNE2", lower 2 bits.

2020-04-25dt-bindings: Fix erroneous 'additionalProperties'Rob Herring6-7/+17
There's several cases of json-schema 'additionalProperties' at the wrong indentation level which has the effect of making them DT properties. This is harmless, but let's fix them so a meta-schema check for this can be added. In all the cases, either the 'additionalProperties' was extra or doesn't work because there's a $ref to more properties. In the latter case, we can use 'unevaluatedProperties' instead.

Oleg pointed out that in the unlikely event the kernel is compiled with CONFIG_PROC_FS unset that release_task will now leak the pid. Move the put_pid out of proc_flush_pid into release_task to fix this and to guarantee I don't make that mistake again. When possible it makes sense to keep get and put in the same function so it can easily been seen how they pair up.

2020-04-24mm: check that mm is still valid in madvise()Linus Torvalds1-0/+18
IORING_OP_MADVISE can end up basically doing mprotect() on the VM of another process, which means that it can race with our crazy core dump handling which accesses the VM state without holding the mmap_sem (because it incorrectly thinks that it is the final user). This is clearly a core dumping problem, but we've never fixed it the right way, and instead have the notion of "check that the mm is still ok" using mmget_still_valid() after getting the mmap_sem for writing in any situation where we're not the original VM thread. See commit 04f5866e41fb ("coredump: fix race condition between mmget_not_zero()/get_task_mm() and core dumping") for more background on this whole mmget_still_valid() thing. You might want to have a barf bag handy when you do. We're discussing just fixing this properly in the only remaining core dumping routines. But even if we do that, let's make do_madvise() do the right thing, and then when we fix core dumping, we can remove all these mmget_still_valid() checks.

2020-04-24afs: Fix to actually set AFS_SERVER_FL_HAVE_EPOCHDavid Howells1-1/+1
AFS keeps track of the epoch value from the rxrpc protocol to note (a) when a fileserver appears to have restarted and (b) when different endpoints of a fileserver do not appear to be associated with the same fileserver (ie. all probes back from a fileserver from all of its interfaces should carry the same epoch). However, the AFS_SERVER_FL_HAVE_EPOCH flag that indicates that we've received the server's epoch is never set, though it is used. Fix this to set the flag when we first receive an epoch value from a probe sent to the filesystem client from the fileserver.
