munlock_vma_pages_range() will still be required, when munlocking but not munmapping a set of pages; but when unmapping a pte, the mlock count will be maintained in much the same way as it will be maintained when mapping in the pte. Which removes the need for munlock_vma_pages_all() on mlocked vmas when munmapping or exiting: eliminating the catastrophic contention on i_mmap_rwsem, and the need for page lock on the pages. There is still a need to update locked_vm accounting according to the munmapped vmas when munmapping: do that in detach_vmas_to_be_unmapped(). exit_mmap() does not need locked_vm updates, so delete unlock_range(). And wasn't I the one who forbade the OOM reaper to attack mlocked vmas, because of the uncertainty in blocking on all those page locks? No fear of that now, so permit the OOM reaper on mlocked vmas.

If counting page mlocks, we must not double-count: follow_page_pte() can tell if a page has already been Mlocked or not, but cannot tell if a pte has already been counted or not: that will have to be done when the pte is mapped in (which lru_cache_add_inactive_or_unevictable() already tracks for new anon pages, but there's no such tracking yet for others). Delete all the FOLL_MLOCK code - faulting in the missing pages will do all that is necessary, without special mlock_vma_page() calls from here. But then FOLL_POPULATE turns out to serve no purpose - it was there so that its absence would tell faultin_page() not to faultin page when setting up VM_LOCKONFAULT areas; but if there's no special work needed here for mlock, then there's no work at all here for VM_LOCKONFAULT. Have I got that right? I've not looked into the history, but see that FOLL_POPULATE goes back before VM_LOCKONFAULT: did it serve a different purpose before? Ah, yes, it was used to skip the old stack guard page. And is it intentional that COW is not broken on existing pages when setting up a VM_LOCKONFAULT area? I can see that being argued either way, and have no reason to disagree with current behaviour.

We have recommended some applications to mlock their userspace, but that turns out to be counter-productive: when many processes mlock the same file, contention on rmap's i_mmap_rwsem can become intolerable at exit: it is needed for write, to remove any vma mapping that file from rmap's tree; but hogged for read by those with mlocks calling page_mlock() (formerly known as try_to_munlock()) on *each* page mapped from the file (the purpose being to find out whether another process has the page mlocked, so therefore it should not be unmlocked yet). Several optimizations have been made in the past: one is to skip page_mlock() when mapcount tells that nothing else has this page mapped; but that doesn't help at all when others do have it mapped. This time around, I initially intended to add a preliminary search of the rmap tree for overlapping VM_LOCKED ranges; but that gets messy with locking order, when in doubt whether a page is actually present; and risks adding even more contention on the i_mmap_rwsem. A solution would be much easier, if only there were space in struct page for an mlock_count... but actually, most of the time, there is space for it - an mlocked page spends most of its life on an unevictable LRU, but since 3.18 removed the scan_unevictable_pages sysctl, that "LRU" has been redundant. Let's try to reuse its page->lru. But leave that until a later patch: in this patch, clear the ground by removing page_mlock(), and all the infrastructure that has gathered around it - which mostly hinders understanding, and will make reviewing new additions harder. Don't mind those old comments about THPs, they date from before 4.5's refcounting rework: splitting is not a risk here. Just keep a minimal version of munlock_vma_page(), as reminder of what it should attend to (in particular, the odd way PGSTRANDED is counted out of PGMUNLOCKED), and likewise a stub for munlock_vma_pages_range(). Move unchanged __mlock_posix_error_return() out of the way, down to above its caller: this series then makes no further change after mlock_fixup(). After this and each following commit, the kernel builds, boots and runs; but with deficiencies which may show up in testing of mlock and munlock. The system calls succeed or fail as before, and mlock remains effective in preventing page reclaim; but meminfo's Unevictable and Mlocked amounts may be shown too low after mlock, grow, then stay too high after munlock: with previously mlocked pages remaining unevictable for too long, until finally unmapped and freed and counts corrected. Normal service will be resumed in "mm/munlock: mlock_pte_range() when mlocking or munlocking".

Daniel Gibson reports that the n_tty code gets line termination wrong in very specific cases: "If you feed a line with exactly 64 chars + terminating newline, and directly afterwards (without reading) another line into a pseudo terminal, the the first read() on the other side will return the 64 char line *without* terminating newline, and the next read() will return the missing terminating newline AND the complete next line (if it fits in the buffer)" and bisected the behavior to commit 3b830a9c ("tty: convert tty_ldisc_ops 'read()' function to take a kernel pointer"). Now, digging deeper, it turns out that the behavior isn't exactly new: what changed in commit 3b830a9c was that the tty line discipline .read() function is now passed an intermediate kernel buffer rather than the final user space buffer. And that intermediate kernel buffer is 64 bytes in size - thus that special case with exactly 64 bytes plus terminating newline. The same problem did exist before, but historically the boundary was not the 64-byte chunk, but the user-supplied buffer size, which is obviously generally bigger (and potentially bigger than N_TTY_BUF_SIZE, which would hide the issue entirely). The reason is that the n_tty canon_copy_from_read_buf() code would look ahead for the EOL character one byte further than it would actually copy. It would then decide that it had found the terminator, and unmark it as an EOL character - which in turn explains why the next read wouldn't then be terminated by it. Now, the reason it did all this in the first place is related to some historical and pretty obscure EOF behavior, see commit ac8f3bf8 ("n_tty: Fix poll() after buffer-limited eof push read") and commit 40d5e090 ("n_tty: Fix EOF push handling"). And the reason for the EOL confusion is that we treat EOF as a special EOL condition, with the EOL character being NUL (aka "__DISABLED_CHAR" in the kernel sources). So that EOF look-ahead also affects the normal EOL handling. This patch just removes the look-ahead that causes problems, because EOL is much more critical than the historical "EOF in the middle of a line that coincides with the end of the buffer" handling ever was. Now, it is possible that we should indeed re-introduce the "look at next character to see if it's a EOF" behavior, but if so, that should be done not at the kernel buffer chunk boundary in canon_copy_from_read_buf(), but at a higher level, when we run out of the user buffer. In particular, the place to do that would be at the top of 'n_tty_read()', where we check if it's a continuation of a previously started read, and there is no more buffer space left, we could decide to just eat the __DISABLED_CHAR at that point. But that would be a separate patch, because I suspect nobody actually cares, and I'd like to get a report about it before bothering.

After commit 4b9d2a73 ("parisc: Switch user access functions to signal errors in r29 instead of r8") bash suddenly started to report those warnings after login: -bash: cannot set terminal process group (-1): Bad file descriptor -bash: no job control in this shell It turned out, that a function call inside a put_user(), e.g.: put_user(vt_do_kdgkbmode(console), (int __user *)arg); clobbered the error register (r29) and thus the put_user() call itself seem to have failed. Rearrange the C-code to pre-calculate the intermediate value and then do the put_user(). Additionally prefer the "+" constraint on pu_err and gu_err registers to tell the compiler that those operands are both read and written by the assembly instruction.

Pull seccomp fixes from Kees Cook: "This fixes a corner case of fatal SIGSYS being ignored since v5.15. Along with the signal fix is a change to seccomp so that seeing another syscall after a fatal filter result will cause seccomp to kill the process harder. Summary: - Force HANDLER_EXIT even for SIGNAL_UNKILLABLE - Make seccomp self-destruct after fatal filter results - Update seccomp samples for easier behavioral demonstration" * tag 'seccomp-v5.17-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux: samples/seccomp: Adjust sample to also provide kill option seccomp: Invalidate seccomp mode to catch death failures signal: HANDLER_EXIT should clear SIGNAL_UNKILLABLE

When the KCONFIG_AUTOCONFIG is specified (e.g. export \ KCONFIG_AUTOCONFIG=output/config/auto.conf), the directory of include/config/ will not be created, so kconfig can't create deps files in it and auto.conf can't be generated.
