5a35770 Luis Chamberlain 24 April 2020, 18:49:15 UTC firmware_loader: revert removal of the fw_fallback_config export 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.

dfc55ac Andrii Nakryiko 22 April 2020, 01:24:07 UTC tools/runqslower: Ensure own vmlinux.h is picked up first 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.

03f87c0 Toke Høiland-Jørgensen 24 April 2020, 13:34:27 UTC bpf: Propagate expected_attach_type when verifying freplace programs 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.

50fe7eb Luke Nelson 22 April 2020, 17:36:30 UTC bpf, x86_32: Fix clobbering of dst for BPF_JSET 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.

5fa9a98 Luke Nelson 22 April 2020, 17:36:29 UTC bpf, x86_32: Fix incorrect encoding in BPF_LDX zero-extension 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.

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.

bc0c4d1 Linus Torvalds 24 April 2020, 18:10:58 UTC mm: check that mm is still valid in madvise() 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.

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.

8b6b802 Rob Herring 21 April 2020, 20:42:02 UTC dt-bindings: Fix command line length limit calling dt-mk-schema As the number of schemas has increased, we're starting to hit the error "execvp: /bin/sh: Argument list too long". This is due to passing all the schema files on the command line to dt-mk-schema. It currently is only with out of tree builds and is intermittent depending on the file path lengths. Commit 2ba06cd8565b ("kbuild: Always validate DT binding examples") made hitting this proplem more likely since the example validation now always gets the full list of schemas. Fix this by passing the schema file list in a pipe and using xargs. We end up doing the find twice, but the time is insignificant compared to the dt-mk-schema time.

f35d129 Xiyu Yang 23 April 2020, 05:13:03 UTC net/x25: Fix x25_neigh refcnt leak when receiving frame x25_lapb_receive_frame() invokes x25_get_neigh(), which returns a reference of the specified x25_neigh object to "nb" with increased refcnt. When x25_lapb_receive_frame() returns, local variable "nb" becomes invalid, so the refcount should be decreased to keep refcount balanced. The reference counting issue happens in one path of x25_lapb_receive_frame(). When pskb_may_pull() returns false, the function forgets to decrease the refcnt increased by x25_get_neigh(), causing a refcnt leak.

9dd44c7 Damien Le Moal 23 April 2020, 03:02:37 UTC null_blk: Fix zoned command handling For write operations issued to a null_blk device with zoned mode enabled, the state and write pointer position of the zone targeted by the command should be checked before badblocks and memory backing are handled as the write may be first failed due to, for instance, a sector position not aligned with the zone write pointer. This order of checking for errors reflects more accuratly the behavior of physical zoned devices. Furthermore, the write pointer position of the target zone should be incremented only and only if no errors are reported by badblocks and memory backing handling. To fix this, introduce the small helper function null_process_cmd() which execute null_handle_badblocks() and null_handle_memory_backed() and use this function in null_zone_write() to correctly handle write requests to zoned null devices depending on the type and state of the write target zone. Also call this function in null_handle_zoned() to process read requests to zoned null devices. null_process_cmd() is called directly from null_handle_cmd() for regular null devices, resulting in no functional change for these type of devices. To have symmetric names, the function null_handle_zoned() is renamed to null_process_zoned_cmd().

Since the tcs_cmd structures passed to this function aren't zero-initialized, then we're left with random wait values. This results in waiting for completion for more commands than is necessary, depending on what's on the stack at the time. Removing the unnecessary if-condition fixes this, but add an explicit memset of the tcs_cmd structure as well to ensure predictable behavior if more tcs_cmd members are added in the future.

Each member has 8 submembers. * we can have more than 4 (PCI) boards, i.e. [board] can be OOB * line is not modulo-ed by anything, so the first line on the second board can be 4, on the 3rd 12 or alike (depending on previously registered boards). It's zero only on the first line of the first board. So even [line] can be OOB, quite soon (with the 2nd registered board already). This code is broken for ages, so just avoid the OOB accesses and don't try to fix it as we would need to find out the correct line number. Use the default: RS232, if we are out. Generally, if anyone needs to set the interface types, a module parameter is past the last thing that should be used for this purpose. The parameters' description says it's for ISA cards anyway.

(Oddly enough, a later version of the same bridge, version 2.03 as opposed to 1.14, doesn't claim to support FUA. Also oddly, the bridge _does_ support FUA when using the UAS transport instead of the Bulk-Only transport -- but this device was blacklisted for uas in commit bc3bdb12bbb3 ("usb-storage: Disable UAS on JMicron SATA enclosure") for apparently unrelated reasons.) This patch adds a usb-storage unusual_devs entry with the BROKEN_FUA flag. This allows the bridge to work properly with usb-storage.

3155f4f Alan Stern 22 April 2020, 20:13:08 UTC USB: hub: Revert commit bd0e6c9614b9 ("usb: hub: try old enumeration scheme first for high speed devices") Commit bd0e6c9614b9 ("usb: hub: try old enumeration scheme first for high speed devices") changed the way the hub driver enumerates high-speed devices. Instead of using the "new" enumeration scheme first and switching to the "old" scheme if that doesn't work, we start with the "old" scheme. In theory this is better because the "old" scheme is slightly faster -- it involves resetting the device only once instead of twice. However, for a long time Windows used only the "new" scheme. Zeng Tao said that Windows 8 and later use the "old" scheme for high-speed devices, but apparently there are some devices that don't like it. William Bader reports that the Ricoh webcam built into his Sony Vaio laptop not only doesn't enumerate under the "old" scheme, it gets hung up so badly that it won't then enumerate under the "new" scheme! Only a cold reset will fix it. Therefore we will revert the commit and go back to trying the "new" scheme first for high-speed devices.
