[merged mm-hotfixes-stable] kprobes-dont-call-disarm_kprobe-for-disabled-kprobes.patch removed from -mm tree

by Andrew Morton

The quilt patch titled Subject: kprobes: don't call disarm_kprobe() for disabled kprobes has been removed from the -mm tree. Its filename was kprobes-dont-call-disarm_kprobe-for-disabled-kprobes.patch This patch was dropped because it was merged into the mm-hotfixes-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: Kuniyuki Iwashima <kuniyu(a)amazon.com> Subject: kprobes: don't call disarm_kprobe() for disabled kprobes Date: Fri, 12 Aug 2022 19:05:09 -0700 The assumption in __disable_kprobe() is wrong, and it could try to disarm an already disarmed kprobe and fire the WARN_ONCE() below. [0] We can easily reproduce this issue. 1. Write 0 to /sys/kernel/debug/kprobes/enabled. # echo 0 > /sys/kernel/debug/kprobes/enabled 2. Run execsnoop. At this time, one kprobe is disabled. # /usr/share/bcc/tools/execsnoop & [1] 2460 PCOMM PID PPID RET ARGS # cat /sys/kernel/debug/kprobes/list ffffffff91345650 r __x64_sys_execve+0x0 [FTRACE] ffffffff91345650 k __x64_sys_execve+0x0 [DISABLED][FTRACE] 3. Write 1 to /sys/kernel/debug/kprobes/enabled, which changes kprobes_all_disarmed to false but does not arm the disabled kprobe. # echo 1 > /sys/kernel/debug/kprobes/enabled # cat /sys/kernel/debug/kprobes/list ffffffff91345650 r __x64_sys_execve+0x0 [FTRACE] ffffffff91345650 k __x64_sys_execve+0x0 [DISABLED][FTRACE] 4. Kill execsnoop, when __disable_kprobe() calls disarm_kprobe() for the disabled kprobe and hits the WARN_ONCE() in __disarm_kprobe_ftrace(). # fg /usr/share/bcc/tools/execsnoop ^C Actually, WARN_ONCE() is fired twice, and __unregister_kprobe_top() misses some cleanups and leaves the aggregated kprobe in the hash table. Then, __unregister_trace_kprobe() initialises tk->rp.kp.list and creates an infinite loop like this. aggregated kprobe.list -> kprobe.list -. ^ | '.__.' In this situation, these commands fall into the infinite loop and result in RCU stall or soft lockup. cat /sys/kernel/debug/kprobes/list : show_kprobe_addr() enters into the infinite loop with RCU. /usr/share/bcc/tools/execsnoop : warn_kprobe_rereg() holds kprobe_mutex, and __get_valid_kprobe() is stuck in the loop. To avoid the issue, make sure we don't call disarm_kprobe() for disabled kprobes.

[merged mm-hotfixes-stable] mm-hugetlb-support-write-faults-in-shared-mappings.patch removed from -mm tree

by Andrew Morton

The quilt patch titled Subject: mm/hugetlb: support write-faults in shared mappings has been removed from the -mm tree. Its filename was mm-hugetlb-support-write-faults-in-shared-mappings.patch This patch was dropped because it was merged into the mm-hotfixes-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: David Hildenbrand <david(a)redhat.com> Subject: mm/hugetlb: support write-faults in shared mappings Date: Thu, 11 Aug 2022 12:34:35 +0200 If we ever get a write-fault on a write-protected page in a shared mapping, we'd be in trouble (again). Instead, we can simply map the page writable.

Reason for this is to avoid the additional overhead when unregistering. Note that this is the case also for !hugetlb and that we will end up with writable PTEs that still have the uffd-wp PTE bit set once we return from hugetlb_wp(). I'm not touching the uffd-wp PTE bit for now, because it seems to be a generic thing -- wp_page_reuse() also doesn't clear it. VM_MAYSHARE handling in hugetlb_fault() for FAULT_FLAG_WRITE indicates that MAP_SHARED handling was at least envisioned, but could never have worked as expected. While at it, make sure that we never end up in hugetlb_wp() on write faults without VM_WRITE, because we don't support maybe_mkwrite() semantics as commonly used in the !hugetlb case -- for example, in wp_page_reuse(). Note that there is no need to do any kind of reservation in hugetlb_fault() in this case ... because we already have a hugetlb page mapped R/O that we will simply map writable and we are not dealing with COW/unsharing.

Its filename was mm-hugetlb-fix-hugetlb-not-supporting-softdirty-tracking.patch This patch was dropped because it was merged into the mm-hotfixes-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: David Hildenbrand <david(a)redhat.com> Subject: mm/hugetlb: fix hugetlb not supporting softdirty tracking Date: Thu, 11 Aug 2022 12:34:34 +0200 Patch series "mm/hugetlb: fix write-fault handling for shared mappings", v2. I observed that hugetlb does not support/expect write-faults in shared mappings that would have to map the R/O-mapped page writable -- and I found two case where we could currently get such faults and would erroneously map an anon page into a shared mapping. Reproducers part of the patches. I propose to backport both fixes to stable trees. The first fix needs a small adjustment. This patch (of 2): Staring at hugetlb_wp(), one might wonder where all the logic for shared mappings is when stumbling over a write-protected page in a shared mapping. In fact, there is none, and so far we thought we could get away with that because e.g., mprotect() should always do the right thing and map all pages directly writable.

[merged mm-hotfixes-stable] mm-uffd-reset-write-protection-when-unregister-with-wp-mode.patch removed from -mm tree

by Andrew Morton

The quilt patch titled Subject: mm/uffd: reset write protection when unregister with wp-mode has been removed from the -mm tree. Its filename was mm-uffd-reset-write-protection-when-unregister-with-wp-mode.patch This patch was dropped because it was merged into the mm-hotfixes-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: Peter Xu <peterx(a)redhat.com> Subject: mm/uffd: reset write protection when unregister with wp-mode Date: Thu, 11 Aug 2022 16:13:40 -0400 The motivation of this patch comes from a recent report and patchfix from David Hildenbrand on hugetlb shared handling of wr-protected page [1]. With the reproducer provided in commit message of [1], one can leverage the uffd-wp lazy-reset of ptes to trigger a hugetlb issue which can affect not only the attacker process, but also the whole system. The lazy-reset mechanism of uffd-wp was used to make unregister faster, meanwhile it has an assumption that any leftover pgtable entries should only affect the process on its own, so not only the user should be aware of anything it does, but also it should not affect outside of the process. But it seems that this is not true, and it can also be utilized to make some exploit easier. So far there's no clue showing that the lazy-reset is important to any userfaultfd users because normally the unregister will only happen once for a specific range of memory of the lifecycle of the process. Considering all above, what this patch proposes is to do explicit pte resets when unregister an uffd region with wr-protect mode enabled. It should be the same as calling ioctl(UFFDIO_WRITEPROTECT, wp=false) right before ioctl(UFFDIO_UNREGISTER) for the user. So potentially it'll make the unregister slower. From that pov it's a very slight abi change, but hopefully nothing should break with this change either. Regarding to the change itself - core of uffd write [un]protect operation is moved into a separate function (uffd_wp_range()) and it is reused in the unregister code path. Note that the new function will not check for anything, e.g. ranges or memory types, because they should have been checked during the previous UFFDIO_REGISTER or it should have failed already. It also doesn't check mmap_changing because we're with mmap write lock held anyway. I added a Fixes upon introducing of uffd-wp shmem+hugetlbfs because that's the only issue reported so far and that's the commit David's reproducer will start working (v5.19+). But the whole idea actually applies to not only file memories but also anonymous. It's just that we don't need to fix anonymous prior to v5.19- because there's no known way to exploit. IOW, this patch can also fix the issue reported in [1] as the patch 2 does.
