fuse_flush() calls write_inode_now() that triggers writeback, but actual writeback will happen later, on fuse_sync_writes(). If an error happens, fuse_writepage_end() will set error bit in mapping->flags. So, we have to check mapping->flags after fuse_sync_writes().

Currently the two are unioned together, but I don't think that's safe. It looks like get_cached_acl could race with the last put in posix_acl_release. get_cached_acl calls atomic_inc_not_zero on a_refcount, but that field could have already been clobbered by call_rcu, and may no longer be zero.

overlay needs underlying fs to support d_type. Recently I put in a patch in to detect this condition and started failing mount if underlying fs did not support d_type. But this breaks existing configurations over kernel upgrade. Those who are running docker (partially broken configuration) with xfs not supporting d_type, are surprised that after kernel upgrade docker does not run anymore. https://github.com/docker/docker/issues/22937#issuecomment-229881315 So instead of erroring out, detect broken configuration and warn about it. This should allow existing docker setups to continue working after kernel upgrade.

The following testcase may result in a page table entries with a invalid CCA field being generated: static void *bindstack; static int sysrqfd; static void protect_low(int protect) { mprotect(bindstack, BINDSTACK_SIZE, protect); } static void sigbus_handler(int signal, siginfo_t * info, void *context) { void *addr = info->si_addr; write(sysrqfd, "x", 1); printf("sigbus, fault address %p (should not happen, but might)\n", addr); abort(); } static void run_bind_test(void) { unsigned int *p = bindstack; p[0] = 0xf001f001; write(sysrqfd, "x", 1); /* Set trap on access to p[0] */ protect_low(PROT_NONE); write(sysrqfd, "x", 1); /* Clear trap on access to p[0] */ protect_low(PROT_READ | PROT_WRITE | PROT_EXEC); write(sysrqfd, "x", 1); /* Check the contents of p[0] */ if (p[0] != 0xf001f001) { write(sysrqfd, "x", 1); /* Reached, but shouldn't be */ printf("badness, shouldn't happen but does\n"); abort(); } } int main(void) { struct sigaction sa; sysrqfd = open("/proc/sysrq-trigger", O_WRONLY); if (sigprocmask(SIG_BLOCK, NULL, &sa.sa_mask)) { perror("sigprocmask"); return 0; } sa.sa_sigaction = sigbus_handler; sa.sa_flags = SA_SIGINFO | SA_NODEFER | SA_RESTART; if (sigaction(SIGBUS, &sa, NULL)) { perror("sigaction"); return 0; } bindstack = mmap(NULL, BINDSTACK_SIZE, PROT_READ | PROT_WRITE | PROT_EXEC, MAP_PRIVATE | MAP_ANONYMOUS, -1, 0); if (bindstack == MAP_FAILED) { perror("mmap bindstack"); return 0; } printf("bindstack: %p\n", bindstack); run_bind_test(); printf("done\n"); return 0; } There are multiple ingredients for this: 1) PAGE_NONE is defined to _CACHE_CACHABLE_NONCOHERENT, which is CCA 3 on all platforms except SB1 where it's CCA 5. 2) _page_cachable_default must have bits set which are not set _CACHE_CACHABLE_NONCOHERENT. 3) Either the defective version of pte_modify for XPA or the standard version must be in used. However pte_modify for the 36 bit address space support is no affected. In that case additional bits in the final CCA mode may generate an invalid value for the CCA field. On the R10000 system where this was tracked down for example a CCA 7 has been observed, which is Uncached Accelerated. Fixed by: 1) Using the proper CCA mode for PAGE_NONE just like for all the other PAGE_* pte/pmd bits. 2) Fix the two affected variants of pte_modify. Further code inspection also shows the same issue to exist in pmd_modify which would affect huge page systems. Issue in pte_modify tracked down by Alastair Bridgewater, PAGE_NONE and pmd_modify issue found by me. The history of this goes back beyond Linus' git history. Chris Dearman's commit 35133692 ("[MIPS] Allow setting of the cache attribute at run time.") missed the opportunity to fix this but it was originally introduced in lmo commit d523832cf12007b3242e50bb77d0c9e63e0b6518 ("Missing from last commit.") and 32cc38229ac7538f2346918a09e75413e8861f87 ("New configuration option CONFIG_MIPS_UNCACHED.")

(Another one for the f_path debacle.) ltp fcntl33 testcase caused an Oops in selinux_file_send_sigiotask. The reason is that generic_add_lease() used filp->f_path.dentry->inode while all the others use file_inode(). This makes a difference for files opened on overlayfs since the former will point to the overlay inode the latter to the underlying inode. So generic_add_lease() added the lease to the overlay inode and generic_delete_lease() removed it from the underlying inode. When the file was released the lease remained on the overlay inode's lock list, resulting in use after free.

- m_start() in fs/namespace.c expects that ns->event is incremented each time a mount added or removed from ns->list. - umount_tree() removes items from the list but does not increment event counter, expecting that it's done before the function is called. - There are some codepaths that call umount_tree() without updating "event" counter. e.g. from __detach_mounts(). - When this happens m_start may reuse a cached mount structure that no longer belongs to ns->list (i.e. use after free which usually leads to infinite loop). This change fixes the above problem by incrementing global event counter before invoking umount_tree().
