This reverts commit 9e46e4dc. kbuild reports a warning in memblock_remove_region() because of a false positive caused by partial reset of the memblock state. Doing the full reset will remove the false positives, but will allow late use of memblock_free() to go unnoticed, so it is better to revert the offending commit.

mbind() calls down into vma_replace_policy() without taking the per-VMA locks, replaces the VMA's vma->vm_policy pointer, and frees the old policy. That's bad; a concurrent page fault might still be using the old policy (in vma_alloc_folio()), resulting in use-after-free. Normally this will manifest as a use-after-free read first, but it can result in memory corruption, including because vma_alloc_folio() can call mpol_cond_put() on the freed policy, which conditionally changes the policy's refcount member. This bug is specific to CONFIG_NUMA, but it does also affect non-NUMA systems as long as the kernel was built with CONFIG_NUMA. Signed-off-by:

lock_vma_under_rcu() tries to guarantee that __anon_vma_prepare() can't be called in the VMA-locked page fault path by ensuring that vma->anon_vma is set. However, this check happens before the VMA is locked, which means a concurrent move_vma() can concurrently call unlink_anon_vmas(), which disassociates the VMA's anon_vma. This means we can get UAF in the following scenario: THREAD 1 THREAD 2 ======== ======== <page fault> lock_vma_under_rcu() rcu_read_lock() mas_walk() check vma->anon_vma mremap() syscall move_vma() vma_start_write() unlink_anon_vmas() <syscall end> handle_mm_fault() __handle_mm_fault() handle_pte_fault() do_pte_missing() do_anonymous_page() anon_vma_prepare() __anon_vma_prepare() find_mergeable_anon_vma() mas_walk() [looks up VMA X] munmap() syscall (deletes VMA X) reusable_anon_vma() [called on freed VMA X] This is a security bug if you can hit it, although an attacker would have to win two races at once where the first race window is only a few instructions wide. This patch is based on some previous discussion with Linus Torvalds on the security list.

If tipc_link_bc_create() fails inside tipc_node_create() for a newly allocated tipc node then we should stop its tipc crypto and free the resources allocated with a call to tipc_crypto_start(). As the node ref is initialized to one to that point, just put the ref on tipc_link_bc_create() error case that would lead to tipc_node_free() be eventually executed and properly clean the node and its crypto resources.

The nla_for_each_nested parsing in function mqprio_parse_nlattr() does not check the length of the nested attribute. This can lead to an out-of-attribute read and allow a malformed nlattr (e.g., length 0) to be viewed as 8 byte integer and passed to priv->max_rate/min_rate. This patch adds the check based on nla_len() when check the nla_type(), which ensures that the length of these two attribute must equals sizeof(u64).

LTP sendfile07 [1], which expects sendfile() to return EAGAIN when transferring data from regular file to a "full" O_NONBLOCK socket, started failing after commit 2dc334f1 ("splice, net: Use sendmsg(MSG_SPLICE_PAGES) rather than ->sendpage()"). sendfile() no longer immediately returns, but now blocks. Removed sock_sendpage() handled this case by setting a MSG_DONTWAIT flag, fix new splice_to_socket() to do the same for O_NONBLOCK sockets.

According to the clarification [1] in the latest napi.rst, the tx processing cannot call any XDP (or page pool) APIs if the "budget" is 0. Because NAPI is called with the budget of 0 (such as netpoll) indicates we may be in an IRQ context, however, we cannot use the page pool from IRQ context.

Commit eda00472 ("mm: make the page fault mmap locking killable") intentionally made it much easier to trigger the "page fault fails because a fatal signal is pending" situation, by having the mmap locking fail early in that case. We have long aborted page faults in other fatal cases when the actual IO for a page is interrupted by SIGKILL - which is particularly useful for the traditional case of NFS hanging due to network issues, but local filesystems could cause it too if you happened to get the SIGKILL while waiting for a page to be faulted in (eg lock_folio_maybe_drop_mmap()). So aborting the page fault wasn't a new condition - but it now triggers earlier, before we even get to 'handle_mm_fault()'. And as a result the error doesn't go through our 'fault_signal_pending()' logic, and doesn't get filtered away there. Normally you'd never even notice, because if a fatal signal is pending, the new SIGSEGV we send ends up being ignored anyway. But it turns out that there is one very noticeable exception: if you enable 'show_unhandled_signals', the aborted page fault will be logged in the kernel messages, and you'll get a scary line looking something like this in your logs: pverados[2183248]: segfault at 55e5a00f9ae0 ip 000055e5a00f9ae0 sp 00007ffc0720bea8 error 14 in perl[55e5a00d4000+195000] likely on CPU 10 (core 4, socket 0) which is rather misleading. It's not really a segfault at all, it's just "the thread was killed before the page fault completed, so we aborted the page fault". Fix this by just making it clear that a pending fatal signal means that any new signal coming in after that is implicitly handled. This will avoid the misleading logging, since now the signal isn't 'unhandled' any more. Reported-and-tested-by:
