2024-11-01xfrm: validate new SA's prefixlen using SA family when sel.family is unsetSabrina Dubroca1-1/+5
[ Upstream commit 3f0ab59e6537c6a8f9e1b355b48f9c05a76e8563 ] This expands the validation introduced in commit 07bf7908950a ("xfrm: Validate address prefix lengths in the xfrm selector.") syzbot created an SA with usersa.sel.family = AF_UNSPEC usersa.sel.prefixlen_s = 128 usersa.family = AF_INET Because of the AF_UNSPEC selector, verify_newsa_info doesn't put limits on prefixlen_{s,d}. But then copy_from_user_state sets x->sel.family to usersa.family (AF_INET). Do the same conversion in verify_newsa_info before validating prefixlen_{s,d}, since that's how prefixlen is going to be used later on.

2024-11-01net: phy: dp83822: Fix reset pin definitionsMichel Alex1-2/+2
commit de96f6a3003513c796bbe4e23210a446913f5c00 upstream. This change fixes a rare issue where the PHY fails to detect a link due to incorrect reset behavior. The SW_RESET definition was incorrectly assigned to bit 14, which is the Digital Restart bit according to the datasheet. This commit corrects SW_RESET to bit 15 and assigns DIG_RESTART to bit 14 as per the datasheet specifications. The SW_RESET define is only used in the phy_reset function, which fully re-initializes the PHY after the reset is performed. The change in the bit definitions should not have any negative impact on the functionality of the PHY. v2: - added Fixes tag - improved commit message Cc: stable@vger.kernel.org Fixes: 5dc39fd5ef35 ("net: phy: DP83822: Add ability to advertise Fiber connection") Signed-off-by: Alex Michel <alex.michel@wiedemann-group.com> Reviewed-by: Andrew Lunn <andrew@lunn.ch> Message-ID: <AS1P250MB0608A798661549BF83C4B43EA9462@AS1P250MB0608.EURP250.PROD.OUTLOOK.COM> Signed-off-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2024-11-01serial: protect uart_port_dtr_rts() in uart_shutdown() tooJiri Slaby (SUSE)1-7/+9
[ Upstream commit 602babaa84d627923713acaf5f7e9a4369e77473 ] Commit af224ca2df29 (serial: core: Prevent unsafe uart port access, part 3) added few uport == NULL checks. It added one to uart_shutdown(), so the commit assumes, uport can be NULL in there. But right after that protection, there is an unprotected "uart_port_dtr_rts(uport, false);" call. That is invoked only if HUPCL is set, so I assume that is the reason why we do not see lots of these reports. Or it cannot be NULL at this point at all for some reason :P. Until the above is investigated, stay on the safe side and move this dereference to the if too. I got this inconsistency from Coverity under CID 1585130. Thanks.

commit 4c262801ea60c518b5bebc22a09f5b78b3147da2 upstream. The existing code moves VF to the same namespace as the synthetic NIC during netvsc_register_vf().

commit 35fdc6e1c16099078bcbd73a6c8f1733ae7f1909 upstream. The Acer Predator G9-593 has a 2+1 speaker system which isn't probed correctly. This patch adds a quirk with the proper pin connections. Note that I do not own this laptop, so I cannot guarantee that this fixes the issue.

2024-11-01KVM: nSVM: Ignore nCR3[4:0] when loading PDPTEs from memorySean Christopherson1-1/+5
commit f559b2e9c5c5308850544ab59396b7d53cfc67bd upstream. Ignore nCR3[4:0] when loading PDPTEs from memory for nested SVM, as bits 4:0 of CR3 are ignored when PAE paging is used, and thus VMRUN doesn't enforce 32-byte alignment of nCR3. In the absolute worst case scenario, failure to ignore bits 4:0 can result in an out-of-bounds read, e.g. if the target page is at the end of a memslot, and the VMM isn't using guard pages. Per the APM: The CR3 register points to the base address of the page-directory-pointer table. The page-directory-pointer table is aligned on a 32-byte boundary, with the low 5 address bits 4:0 assumed to be 0. And the SDM's much more explicit: 4:0 Ignored Note, KVM gets this right when loading PDPTRs, it's only the nSVM flow that is broken.

2024-11-01nilfs2: fix kernel bug due to missing clearing of buffer delay flagRyusuke Konishi1-2/+4
commit 6ed469df0bfbef3e4b44fca954a781919db9f7ab upstream. Syzbot reported that after nilfs2 reads a corrupted file system image and degrades to read-only, the BUG_ON check for the buffer delay flag in submit_bh_wbc() may fail, causing a kernel bug. This is because the buffer delay flag is not cleared when clearing the buffer state flags to discard a page/folio or a buffer head. So, fix this. This became necessary when the use of nilfs2's own page clear routine was expanded. This state inconsistency does not occur if the buffer is written normally by log writing.

detection issue commit 8fa73ee44daefc884c53a25158c25a4107eb5a94 upstream. Add a DMI quirk for Samsung Galaxy Book2 to fix an initial lid state detection issue. The _LID device incorrectly returns the lid status as "closed" during boot, causing the system to enter a suspend loop right after booting. The quirk ensures that the correct lid state is reported initially, preventing the system from immediately suspending after startup. It only addresses the initial lid state detection and ensures proper system behavior upon boot.

2024-11-01btrfs: zoned: fix zone unusable accounting for freed reserved extentNaohiro Aota1-0/+2
commit bf9821ba4792a0d9a2e72803ae7b4341faf3d532 upstream. When btrfs reserves an extent and does not use it (e.g, by an error), it calls btrfs_free_reserved_extent() to free the reserved extent. In the process, it calls btrfs_add_free_space() and then it accounts the region bytes as block_group->zone_unusable. However, it leaves the space_info->bytes_zone_unusable side not updated. As a result, ENOSPC can happen while a space_info reservation succeeded. The reservation is fine because the freed region is not added in space_info->bytes_zone_unusable, leaving that space as "free". OTOH, corresponding block group counts it as zone_unusable and its allocation pointer is not rewound, we cannot allocate an extent from that block group. That will also negate space_info's async/sync reclaim process, and cause an ENOSPC error from the extent allocation process. Fix that by returning the space to space_info->bytes_zone_unusable. Ideally, since a bio is not submitted for this reserved region, we should return the space to free space and rewind the allocation pointer. But, it needs rework on extent allocation handling, so let it work in this way for now.

2024-11-01r8169: avoid unsolicited interruptsHeiner Kallweit1-1/+3
[ Upstream commit 10ce0db787004875f4dba068ea952207d1d8abeb ] It was reported that after resume from suspend a PCI error is logged and connectivity is broken. Error message is: PCI error (cmd = 0x0407, status_errs = 0x0000) The message seems to be a red herring as none of the error bits is set, and the PCI command register value also is normal. Exception handling for a PCI error includes a chip reset what apparently brakes connectivity here. The interrupt status bit triggering the PCI error handling isn't actually used on PCIe chip versions, so it's not clear why this bit is set by the chip. Fix this by ignoring this bit on PCIe chip versions.

2024-11-01arm64: Force position-independent veneersMark Rutland1-1/+1
[ Upstream commit 9abe390e689f4f5c23c5f507754f8678431b4f72 ] Certain portions of code always need to be position-independent regardless of CONFIG_RELOCATABLE, including code which is executed in an idmap or which is executed before relocations are applied. In some kernel configurations the LLD linker generates position-dependent veneers for such code, and when executed these result in early boot-time failures. Marc Zyngier encountered a boot failure resulting from this when building a (particularly cursed) configuration with LLVM, as he reported to the list: https://lore.kernel.org/linux-arm-kernel/86wmjwvatn.wl-maz@kernel.org/ In Marc's kernel configuration, the .head.text and .rodata.text sections end up more than 128MiB apart, requiring a veneer to branch between the two: | [mark@lakrids:~/src/linux]% usekorg 14.1.0 aarch64-linux-objdump -t vmlinux | grep -w _text | ffff800080000000 g .head.text 0000000000000000 _text | [mark@lakrids:~/src/linux]% usekorg 14.1.0 aarch64-linux-objdump -t vmlinux | grep -w primary_entry | ffff8000889df0e0 g .rodata.text 000000000000006c primary_entry, ... consequently, LLD inserts a position-dependent veneer for the branch from _stext (in .head.text) to primary_entry (in .rodata.text): | ffff800080000000 <_text>: | ffff800080000000: fa405a4d ccmp x18, #0x0, #0xd, pl // pl = nfrst | ffff800080000004: 14003fff b ffff800080010000 <__AArch64AbsLongThunk_primary_entry> ... | ffff800080010000 <__AArch64AbsLongThunk_primary_entry>: | ffff800080010000: 58000050 ldr x16, ffff800080010008 <__AArch64AbsLongThunk_primary_entry+0x8> | ffff800080010004: d61f0200 br x16 | ffff800080010008: 889df0e0 .word 0x889df0e0 | ffff80008001000c: ffff8000 .word 0xffff8000 ... and as this is executed early in boot before the kernel is mapped in TTBR1 this results in a silent boot failure. Fix this by passing '--pic-veneer' to the linker, which will cause the linker to use position-independent veneers, e.g. | ffff800080000000 <_text>: | ffff800080000000: fa405a4d ccmp x18, #0x0, #0xd, pl // pl = nfrst | ffff800080000004: 14003fff b ffff800080010000 <__AArch64ADRPThunk_primary_entry> ... | ffff800080010000 <__AArch64ADRPThunk_primary_entry>: | ffff800080010000: f004e3f0 adrp x16, ffff800089c8f000 <__idmap_text_start> | ffff800080010004: 91038210 add x16, x16, #0xe0 | ffff800080010008: d61f0200 br x16 I've opted to pass '--pic-veneer' unconditionally, as: * In addition to solving the boot failure, these sequences are generally nicer as they require fewer instructions and don't need to perform data accesses. * While the position-independent veneer sequences have a limited +/-2GiB range, this is not a new restriction. Even kernels built with CONFIG_RELOCATABLE=n are limited to 2GiB in size as we have several structues using 32-bit relative offsets and PPREL32 relocations, which are similarly limited to +/-2GiB in range. These include extable entries, jump table entries, and alt_instr entries. * GNU LD defaults to using position-independent veneers, and supports the same '--pic-veneer' option, so this change is not expected to adversely affect GNU LD.

2024-11-01exec: don't WARN for racy path_noexec checkMateusz Guzik1-12/+9
[ Upstream commit 0d196e7589cefe207d5d41f37a0a28a1fdeeb7c6 ] Both i_mode and noexec checks wrapped in WARN_ON stem from an artifact of the previous implementation. They used to legitimately check for the condition, but that got moved up in two commits: 633fb6ac3980 ("exec: move S_ISREG() check earlier") 0fd338b2d2cd ("exec: move path_noexec() check earlier") Instead of being removed said checks are WARN_ON'ed instead, which has some debug value. However, the spurious path_noexec check is racy, resulting in unwarranted warnings should someone race with setting the noexec flag. One can note there is more to perm-checking whether execve is allowed and none of the conditions are guaranteed to still hold after they were tested for. Additionally this does not validate whether the code path did any perm checking to begin with -- it will pass if the inode happens to be regular. Keep the redundant path_noexec() check even though it's mindless nonsense checking for guarantee that isn't given so drop the WARN. Reword the commentary and do small tidy ups while here.

2024-11-01usb: dwc3: core: Fix system suspend on TI AM62 platformsRoger Quadros2-0/+22
[ Upstream commit 705e3ce37bccdf2ed6f848356ff355f480d51a91 ] Since commit 6d735722063a ("usb: dwc3: core: Prevent phy suspend during init"), system suspend is broken on AM62 TI platforms. Before that commit, both DWC3_GUSB3PIPECTL_SUSPHY and DWC3_GUSB2PHYCFG_SUSPHY bits (hence forth called 2 SUSPHY bits) were being set during core initialization and even during core re-initialization after a system suspend/resume. These bits are required to be set for system suspend/resume to work correctly on AM62 platforms. Since that commit, the 2 SUSPHY bits are not set for DEVICE/OTG mode if gadget driver is not loaded and started. For Host mode, the 2 SUSPHY bits are set before the first system suspend but get cleared at system resume during core re-init and are never set again. This patch resovles these two issues by ensuring the 2 SUSPHY bits are set before system suspend and restored to the original state during system resume.

2024-11-01KVM: s390: gaccess: Check if guest address is in memslotNico Boehr2-6/+12
[ Upstream commit e8061f06185be0a06a73760d6526b8b0feadfe52 ] Previously, access_guest_page() did not check whether the given guest address is inside of a memslot. This is not a problem, since kvm_write_guest_page/kvm_read_guest_page return -EFAULT in this case. However, -EFAULT is also returned when copy_to/from_user fails. When emulating a guest instruction, the address being outside a memslot usually means that an addressing exception should be injected into the guest. Failure in copy_to/from_user however indicates that something is wrong in userspace and hence should be handled there. To be able to distinguish these two cases, return PGM_ADDRESSING in access_guest_page() when the guest address is outside guest memory. In access_guest_real(), populate vcpu->arch.pgm.code such that kvm_s390_inject_prog_cond() can be used in the caller for injecting into the guest (if applicable). Since this adds a new return value to access_guest_page(), we need to make sure that other callers are not confused by the new positive return value. There are the following users of access_guest_page(): - access_guest_with_key() does the checking itself (in guest_range_to_gpas()), so this case should never happen. Even if, the handling is set up properly. - access_guest_real() just passes the return code to its callers, which are: - read_guest_real() - see below - write_guest_real() - see below There are the following users of read_guest_real(): - ar_translation() in gaccess.c which already returns PGM_* - setup_apcb10(), setup_apcb00(), setup_apcb11() in vsie.c which always return -EFAULT on read_guest_read() nonzero return - no change - shadow_crycb(), handle_stfle() always present this as validity, this could be handled better but doesn't change current behaviour - no change There are the following users of write_guest_real(): - kvm_s390_store_status_unloaded() always returns -EFAULT on write_guest_real() failure.
