[PATCHv2] exec: Fix a deadlock in ptrace

by Bernd Edlinger

This fixes a deadlock in the tracer when tracing a multi-threaded application that calls execve while more than one thread are running. I observed that when running strace on the gcc test suite, it always blocks after a while, when expect calls execve, because other threads have to be terminated. They send ptrace events, but the strace is no longer able to respond, since it is blocked in vm_access. The deadlock is always happening when strace needs to access the tracees process mmap, while another thread in the tracee starts to execve a child process, but that cannot continue until the PTRACE_EVENT_EXIT is handled and the WIFEXITED event is received: strace D 0 30614 30584 0x00000000 Call Trace: __schedule+0x3ce/0x6e0 schedule+0x5c/0xd0 schedule_preempt_disabled+0x15/0x20 __mutex_lock.isra.13+0x1ec/0x520 __mutex_lock_killable_slowpath+0x13/0x20 mutex_lock_killable+0x28/0x30 mm_access+0x27/0xa0 process_vm_rw_core.isra.3+0xff/0x550 process_vm_rw+0xdd/0xf0 __x64_sys_process_vm_readv+0x31/0x40 do_syscall_64+0x64/0x220 entry_SYSCALL_64_after_hwframe+0x44/0xa9 expect D 0 31933 30876 0x80004003 Call Trace: __schedule+0x3ce/0x6e0 schedule+0x5c/0xd0 flush_old_exec+0xc4/0x770 load_elf_binary+0x35a/0x16c0 search_binary_handler+0x97/0x1d0 __do_execve_file.isra.40+0x5d4/0x8a0 __x64_sys_execve+0x49/0x60 do_syscall_64+0x64/0x220 entry_SYSCALL_64_after_hwframe+0x44/0xa9 The proposed solution is to have a second mutex that is used in mm_access, so it is allowed to continue while the dying threads are not yet terminated. I also took the opportunity to improve the documentation of prepare_creds, which is obviously out of sync.

For 1G hugepages, huge_pte_offset() wants to return NULL or pudp, but it may return a wrong 'pmdp' if there is a race. Please look at the following code snippet: ... pud = pud_offset(p4d, addr); if (sz != PUD_SIZE && pud_none(*pud)) return NULL; /* hugepage or swap? */ if (pud_huge(*pud) || !pud_present(*pud)) return (pte_t *)pud; pmd = pmd_offset(pud, addr); if (sz != PMD_SIZE && pmd_none(*pmd)) return NULL; /* hugepage or swap? */ if (pmd_huge(*pmd) || !pmd_present(*pmd)) return (pte_t *)pmd; ... The following sequence would trigger this bug: 1. CPU0: sz = PUD_SIZE and *pud = 0 , continue 1. CPU0: "pud_huge(*pud)" is false 2. CPU1: calling hugetlb_no_page and set *pud to xxxx8e7(PRESENT) 3. CPU0: "!pud_present(*pud)" is false, continue 4. CPU0: pmd = pmd_offset(pud, addr) and maybe return a wrong pmdp However, we want CPU0 to return NULL or pudp. We can avoid this race by reading the pud only once. What's more, we also use READ_ONCE to access the entries for safety (i.e. avoid the compilier mischief) Link: http://lkml.kernel.org/r/1582342427-230392-1-git-send-email-longpeng2@huawe… Signed-off-by: Longpeng <longpeng2(a)huawei.com> Cc: Matthew Wilcox <willy(a)infradead.org> Cc: Sean Christopherson <sean.j.christopherson(a)intel.com> Cc: Mike Kravetz <mike.kravetz(a)oracle.com> Cc: <stable(a)vger.kernel.org> Signed-off-by: Andrew Morton <akpm(a)linux-foundation.org> --- mm/hugetlb.c | 18 ++++++++++-------- 1 file changed, 10 insertions(+), 8 deletions(-) --- a/mm/hugetlb.c~mm-hugetlb-fix-a-addressing-exception-caused-by-huge_pte_offset +++ a/mm/hugetlb.c @@ -4910,28 +4910,30 @@ pte_t *huge_pte_offset(struct mm_struct { pgd_t *pgd; p4d_t *p4d; - pud_t *pud; - pmd_t *pmd; + pud_t *pud, pud_entry; + pmd_t *pmd, pmd_entry; pgd = pgd_offset(mm, addr); - if (!pgd_present(*pgd)) + if (!pgd_present(READ_ONCE(*pgd))) return NULL; p4d = p4d_offset(pgd, addr); - if (!p4d_present(*p4d)) + if (!p4d_present(READ_ONCE(*p4d))) return NULL; pud = pud_offset(p4d, addr); - if (sz != PUD_SIZE && pud_none(*pud)) + pud_entry = READ_ONCE(*pud); + if (sz != PUD_SIZE && pud_none(pud_entry)) return NULL; /* hugepage or swap? */ - if (pud_huge(*pud) || !pud_present(*pud)) + if (pud_huge(pud_entry) || !pud_present(pud_entry)) return (pte_t *)pud; pmd = pmd_offset(pud, addr); - if (sz != PMD_SIZE && pmd_none(*pmd)) + pmd_entry = READ_ONCE(*pmd); + if (sz != PMD_SIZE && pmd_none(pmd_entry)) return NULL; /* hugepage or swap? */ - if (pmd_huge(*pmd) || !pmd_present(*pmd)) + if (pmd_huge(pmd_entry) || !pmd_present(pmd_entry)) return (pte_t *)pmd; return NULL; _ Patches currently in -mm which might be from longpeng2(a)huawei.com are

Handling of patches missing in stable releases based on Fixes: tags

by Guenter Roeck

Hi, we now have a script that identifies patches in stable releases which were later fixed upstream, but the fix was not applied to the respective stable releases. We identify such patches based on Fixes: tags in the upstream kernel. Example: Upstream commit c54c7374ff4 ("drm/dp_mst: Skip validating ports during destruction, just ref") was applied to v4.4.y as commit 05d994f68019. It was later reverted upstream with commit 9765635b307, but the revert has (at least not yet) found its way into v4.4.y. This is an easy example, where the revert should (or at least I think it should) be applied to v4.4.y (and possibly to later kernels - I didn't check). A more tricky patch is commit 3ef240eaff36 ("futex: Prevent exit livelock") in v5.4.y, which was later fixed upstream with commit 51bfb1d11d6 ("futex: Fix kernel-doc notation warning"). I am not entirely sure what to do with that, given that it only fixes documentation (though that may of course also be valuable). How should we handle this ? Would it be ok to send half-automated requests to the stable mailing list, for example with basic test results ? Thanks, Guenter

[PATCH] bonding: do not enslave CAN devices

by Oliver Hartkopp

Since commit 8df9ffb888c ("can: make use of preallocated can_ml_priv for per device struct can_dev_rcv_lists") the device specific CAN receive filter lists are stored in netdev_priv() and dev->ml_priv points to these filters. In the bug report Syzkaller enslaved a vxcan1 CAN device and accessed the bonding device with a PF_CAN socket which lead to a crash due to an access of an unhandled bond_dev->ml_priv pointer. Deny to enslave CAN devices by the bonding driver as the resulting bond_dev pretends to be a CAN device by copying dev->type without really being one.

Aborted tests ------------- Tests that didn't complete running successfully are marked with ⚡⚡⚡. If this was caused by an infrastructure issue, we try to mark that explicitly in the report. Waived tests ------------ If the test run included waived tests, they are marked with 🚧. Such tests are executed but their results are not taken into account. Tests are waived when their results are not reliable enough, e.g. when they're just introduced or are being fixed. Testing timeout --------------- We aim to provide a report within reasonable timeframe. Tests that haven't finished running yet are marked with ⏱.
