highmem: fix a memory copy problem in memcpy_from_folio

2023-12-07T00:12:49Z

Clang static checker complains that value stored to 'from' is never read. And memcpy_from_folio() only copy the last chunk memory from folio to destination. Use 'to += chunk' to replace 'from += chunk' to fix this typo problem.

hugetlb: fix null-ptr-deref in hugetlb_vma_lock_write

2023-12-07T00:12:43Z

The routine __vma_private_lock tests for the existence of a reserve map associated with a private hugetlb mapping. A pointer to the reserve map is in vma->vm_private_data. __vma_private_lock was checking the pointer for NULL. However, it is possible that the low bits of the pointer could be used as flags. In such instances, vm_private_data is not NULL and not a valid pointer. This results in the null-ptr-deref reported by syzbot: general protection fault, probably for non-canonical address 0xdffffc000000001d: 0000 [#1] PREEMPT SMP KASAN KASAN: null-ptr-deref in range [0x00000000000000e8-0x00000000000000ef] CPU: 0 PID: 5048 Comm: syz-executor139 Not tainted 6.6.0-rc7-syzkaller-00142-g88 8cf78c29e2 #0 Hardware name: Google Google Compute Engine/Google Compute Engine, BIOS Google 1 0/09/2023 RIP: 0010:__lock_acquire+0x109/0x5de0 kernel/locking/lockdep.c:5004 ...

bpf: Fix prog_array_map_poke_run map poke update

2023-12-06T21:40:16Z

Lee pointed out issue found by syscaller [0] hitting BUG in prog array map poke update in prog_array_map_poke_run function due to error value returned from bpf_arch_text_poke function. There's race window where bpf_arch_text_poke can fail due to missing bpf program kallsym symbols, which is accounted for with check for -EINVAL in that BUG_ON call. The problem is that in such case we won't update the tail call jump and cause imbalance for the next tail call update check which will fail with -EBUSY in bpf_arch_text_poke. I'm hitting following race during the program load: CPU 0 CPU 1 bpf_prog_load bpf_check do_misc_fixups prog_array_map_poke_track map_update_elem bpf_fd_array_map_update_elem prog_array_map_poke_run bpf_arch_text_poke returns -EINVAL bpf_prog_kallsyms_add After bpf_arch_text_poke (CPU 1) fails to update the tail call jump, the next poke update fails on expected jump instruction check in bpf_arch_text_poke with -EBUSY and triggers the BUG_ON in prog_array_map_poke_run. Similar race exists on the program unload. Fixing this by moving the update to bpf_arch_poke_desc_update function which makes sure we call __bpf_arch_text_poke that skips the bpf address check. Each architecture has slightly different approach wrt looking up bpf address in bpf_arch_text_poke, so instead of splitting the function or adding new 'checkip' argument in previous version, it seems best to move the whole map_poke_run update as arch specific code.

Merge tag 'ffa-fixes-6.7' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux into arm/fixes

2023-12-06T16:35:29Z

Arm FF-A fixes for v6.7 A bunch of fixes addressing issues around the notification support that was added this cycle. They address issue in partition IDs handling in ffa_notification_info_get(), notifications cleanup path and the size of the allocation in ffa_partitions_cleanup(). It also adds check for the notification enabled state so that the drivers registering the callbacks can be rejected if not enabled/supported. It also moves the partitions setup operation after the notification initialisation so that the driver has the correct state for notification enabled/supported before the partitions are initialised/setup. It also now allows FF-A initialisation to complete successfully even when the notification initialisation fails as it is an optional support in the specification. Initial support just allowed it only if the firmware didn't support notifications. Finally, it also adds a fix for smatch warning by declaring ffa_bus_type structure in the header. * tag 'ffa-fixes-6.7' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux: firmware: arm_ffa: Fix ffa_notification_info_get() IDs handling firmware: arm_ffa: Fix the size of the allocation in ffa_partitions_cleanup() firmware: arm_ffa: Fix FFA notifications cleanup path firmware: arm_ffa: Add checks for the notification enabled state firmware: arm_ffa: Setup the partitions after the notification initialisation firmware: arm_ffa: Allow FF-A initialisation even when notification fails firmware: arm_ffa: Declare ffa_bus_type structure in the header Link: https://lore.kernel.org/r/20231116191603.929767-1-sudeep.holla@arm.com Signed-off-by: Arnd Bergmann
