This commit fixes a couple of bad\ncalculations and a broken epilogue in the exception handlers.

No race, no memory-layout luck, and the Niagara copy routines are auto-selected by CPU type with no special kernel config.\nPR:L - Any unprivileged local user can pass a partially-invalid user pointer to ordinary syscalls such as read(), write(), sendmsg() or ioctl(); no capability, namespace or filesystem privilege is involved.\nUI:N - The attacking process triggers the faulting copy entirely on its own via a syscall; no action by another user or administrator is needed.\nS:U - The corruption is confined to the kernel of the running system \u2014 no hypervisor, IOMMU or sandbox boundary is crossed.\nC:H - The under-reported remainder leaves 8\u201316 bytes of the kernel destination buffer unzeroed by _inline_copy_from_user()\u0027s memset and treated as valid user data, repeatedly leaking stale kernel heap/stack contents into buffers that syscalls process or write back; the missing register-window restore additionally exposes kernel pointers as the copy\u0027s return value.\nI:H - The dead `restore` makes raw_copy_from_user return a destination pointer instead of a byte count, so memset(to + (n - res), 0, res) becomes an unbounded out-of-bounds kernel write, and the unpopped register window leaves the caller with a corrupted %sp/%fp and a wrong saved return address \u2014 memory corruption with attacker-influenced pointers and hijackable control flow.\nA:H - Returning without restoring the register window desynchronizes the entire SPARC window stack and the caller\u0027s stack frame, and the giant memset length guarantees a wild write; the result is an immediate kernel oops/panic on every triggered fault, trivially repeatable by an unprivileged user."

It does not\ncontain the phys of the expander.  Thus, it is wrong to use attached_phy\nto index the pm8001_ha-\u003ephy array for a device behind an expander.\n\nThus, we can only clear phy_attached for devices that are directly\nattached."

A physical variant exists (hot-unplugging a drive on an expander phy \u2265 16), but the local suspend path is both reachable and more severe.\nAC:L - Once a SAS device is enumerated behind an expander with more than 16 phys \u2014 the standard 24/28/36-phy JBOD backplane configuration described in the commit \u2014 every suspend or removal event deterministically performs the OOB write, with no race to win and no unpredictable state required. The offending index is a stable property of the cabled topology, which the attacker can repeatedly re-trigger.\nPR:L - An unprivileged user with an active local session can invoke system suspend through the default logind/polkit policy, and `sas_suspend_devices()` calls `lldd_dev_gone` for every device on `port-\u003edev_list`, including expander children, driving the OOB write without any capability. No CAP_SYS_MODULE or root is needed on this path.\nUI:N - The attacker triggers suspend or device teardown directly; no separate victim needs to open a file, mount a filesystem, or take any action.\nS:U - The corruption is confined to kernel heap memory managed by the same kernel security authority; there is no VM, IOMMU, or sandbox boundary crossed.\nC:H - A controllable-offset out-of-bounds write into and beyond a large kmalloc\u0027d `pm8001_hba_info` object corrupts adjacent slab objects \u2014 zeroing a length, index, or pointer byte in a neighbouring structure is a standard route to over-read and kernel memory disclosure. Per kernel scoring guidance, memory corruption leveragable for info disclosure is High.\nI:H - This is a direct out-of-bounds write (`phy[idx].phy_attached = 0` with idx up to 127 into a 16-element array), landing in `asd_sas_port` list heads/spinlocks/pointers, the `devices`/`ccb_info` pointers, and ultimately in unrelated heap objects \u2014 a cross-object write primitive with attacker-influenced offset.\nA:H - The bug is confirmed by UBSAN as an array-index-out-of-bounds, and zeroing bytes of live `list_head`s, spinlocks, and kernel pointers reliably produces oopses, corrupted list traversal, or panic on the next use of the clobbered structure."

On AX88772B, autosuspend shows no\nmeasurable power saving with current driver (no link partner, admin\nup/down). The ~0.453 W -\u003e ~0.248 W drop on v6.1 comes from phylib powering\nthe PHY off on admin-down, not from USB autosuspend.\n\nThe real hazard is that with runtime PM enabled, ndo_open() (under RTNL)\nmay synchronously trigger autoresume (usb_autopm_get_interface()) into\nasix_resume() while the USB PM lock is held. Resume paths then invoke\nphylink/phylib and MDIO, which also expect RTNL, leading to possible\ndeadlocks or PM lock vs MDIO wake issues.\n\nTo avoid this, keep the device runtime-PM active by taking a usage\nreference in ax88772_bind() and dropping it in unbind(). A non-zero PM\nusage count blocks runtime suspend regardless of userspace policy\n(.../power/control - pm_runtime_allow/forbid), making this approach\nrobust against sysfs overrides.\n\nHolding a runtime-PM usage ref does not affect system-wide suspend;\nsystem sleep/resume callbacks continue to run as before."

The program returns struct xdp_md\u0027s\negress_ifindex, and the latter is only allowed to be accessed under mentioned\nexpected_attach_type. progB is then inserted into the tailcall which progA\ncalls.\n\nThe underlying issue goes beyond XDP though. Another example are programs\nof type BPF_PROG_TYPE_CGROUP_SOCK_ADDR. sock_addr_is_valid_access() as well\nas sock_addr_func_proto() have different logic depending on the programs\u0027\nexpected_attach_type. Similarly, a program attached to BPF_CGROUP_INET4_GETPEERNAME\nshould not be allowed doing a tailcall into a program which calls bpf_bind()\nout of BPF which is only enabled for BPF_CGROUP_INET4_CONNECT.\n\nIn short, specifying expected_attach_type allows to open up additional\nfunctionality or restrictions beyond what the basic bpf_prog_type enables.\nThe use of tailcalls must not violate these constraints. Fix it by enforcing\nexpected_attach_type in __bpf_prog_map_compatible().\n\nNote that we only enforce this for tailcall maps, but not for BPF devmaps or\ncpumaps: There, the programs are invoked through dev_map_bpf_prog_run*() and\ncpu_map_bpf_prog_run*() which set up a new environment / context and therefore\nthese situations are not prone to this issue."

No network-supplied data introduces the incompatible tail call, so local access is required.\nAC:L - Exploitation is fully deterministic: the attacker authors and loads both programs, owns the prog array, and controls exactly when the tail call executes; there is no race and no memory-layout condition needed for the mis-typed context dereference to occur.\nPR:L - A basic local user with BPF program-loading access can create the prog array and the two mismatched programs; this matches the established scoring of comparable BPF verifier-constraint bypasses, and containerized/delegated-token deployments grant exactly this level without full administrative rights.\nUI:N - The attacker performs every step \u2014 program load, map update, and program invocation \u2014 entirely on their own; no victim action or cooperation is involved.\nS:U - The mis-typed context dereference and any resulting corruption occur within the kernel that is already the vulnerable component, so impact stays inside a single security authority.\nC:H - xdp_init_buff() never initializes xdp_buff-\u003etxq, so a tail-called BPF_XDP_DEVMAP program reading egress_ifindex dereferences attacker-groomable uninitialized stack memory twice and returns the resulting kernel dword into BPF, which can be exfiltrated through a map \u2014 an effectively arbitrary kernel read primitive.\nI:H - Bypassing expected_attach_type lets a program execute helpers and context writes the running hook never validated \u2014 e.g. bpf_bind()/__inet_bind() invoked from a GETPEERNAME hook mutates live socket binding and hash state without the socket lock, and msg_src_ip4/6 or sockopt level/optname/retval writes land on NULL or wrong-type kernel fields.\nA:H - The reported case is an immediate NULL pointer dereference on xdp_buff-\u003etxq in bpf_prog_test_run_xdp(), and in driver XDP paths the uninitialized txq produces a wild pointer dereference \u2014 either way a kernel oops that the attacker can trigger repeatedly."

This lead to __copy_from_iter()\nreturning impossible values instead of the actual number of bytes it was\nable to copy.\n\nThe BUG_ON has been reported in\nhttps://lore.kernel.org/r/b14f55642207e63e907965e209f6323a0df6dcee.camel@physik.fu-berlin.de\n\nThe referenced commit introduced exception handlers on user-space memory\nreferences in copy_from_user and copy_to_user. These handlers return from\nthe respective function and calculate the remaining bytes left to copy\nusing the current register contents. The exception handlers expect that\n%o2 has already been masked during the bulk copy loop, but the masking was\nperformed after that loop. This will fix the return value of copy_from_user\nand copy_to_user in the faulting case. The behaviour of memcpy stays\nunchanged."

There is no race and no dependence on unpredictable memory layout.\nPR:L - Any unprivileged local user can trigger this with ordinary `write(2)`/`read(2)`/`ioctl(2)` plus `mmap`/`munmap`; no capability, namespace trick, or privileged device access is required.\nUI:N - The attacking process performs the entire sequence itself \u2014 mapping the partially-valid buffer and issuing the syscall. No victim action is involved.\nS:U - The corruption is confined to kernel memory managed by the same kernel security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The over-reported count underflows `iterate_iovec()`/`iterate_ubuf()` accounting, causing the iterator to walk past the end of the kernel iovec array and treat arbitrary kernel memory as iovec descriptors, and the resulting heap corruption primitive can be leveraged for kernel memory disclosure.\nI:H - `_inline_copy_from_user()`\u0027s tail `memset(to + (n - res), 0, res)` with `res \u003e n` wraps the pointer and zeroes up to ~n bytes of kernel heap memory *before* the destination buffer \u2014 an attacker-sized out-of-bounds write (4 KB underflow for a 4 KB copy) into adjacent slab objects, a well-known privilege-escalation primitive.\nA:H - The bug was reported as a hard `BUG_ON` panic in ext4\u0027s large-folio write path, and the `size_t` underflow of `iter-\u003ecount`/`len` also drives runaway iteration loops \u2014 both are full kernel denial of service."

These handlers return from\nthe respective function and calculate the remaining bytes left to copy\nusing the current register contents. This commit fixes a couple of bad\ncalculations.
