Pull powerpc updates from Michael Ellerman: - Add support for (optionally) using queued spinlocks & rwlocks. - Support for a new faster system call ABI using the scv instruction on Power9 or later. - Drop support for the PROT_SAO mmap/mprotect flag as it will be unsupported on Power10 and future processors, leaving us with no way to implement the functionality it requests. This risks breaking userspace, though we believe it is unused in practice. - A bug fix for, and then the removal of, our custom stack expansion checking. We now allow stack expansion up to the rlimit, like other architectures. - Remove the remnants of our (previously disabled) topology update code, which tried to react to NUMA layout changes on virtualised systems, but was prone to crashes and other problems. - Add PMU support for Power10 CPUs. - A change to our signal trampoline so that we don't unbalance the link stack (branch return predictor) in the signal delivery path. - Lots of other cleanups, refactorings, smaller features and so on as usual.

Joerg Roedel authored
The code for preallocate_vmalloc_pages() was written under the assumption that the p4d_offset() and pud_offset() functions will perform present checks before dereferencing the parent entries. This assumption is wrong an leads to a bug in the code which causes the physical address found in the PGD be used as a page-table page, even if the PGD is not present. So the code flow currently is: pgd = pgd_offset_k(addr); p4d = p4d_offset(pgd, addr); if (p4d_none(*p4d)) p4d = p4d_alloc(&init_mm, pgd, addr); This lacks a check for pgd_none() at least, the correct flow would be: pgd = pgd_offset_k(addr); if (pgd_none(*pgd)) p4d = p4d_alloc(&init_mm, pgd, addr); else p4d = p4d_offset(pgd, addr); But this is the same flow that the p4d_alloc() and the pud_alloc() functions use internally, so there is no need to duplicate them. Remove the p?d_none() checks from the function and just call into p4d_alloc() and pud_alloc() to correctly pre-allocate the PGD entries. Reported-and-tested-by:

Commit 58552408 ("random: random.h should include archrandom.h, not the other way around") tries to fix a problem with recursive inclusion of linux/random.h and arch/archrandom.h for arm64. Unfortunately, this results in the following compile error if ARCH_RANDOM is disabled. arch/arm64/kernel/kaslr.c: In function 'kaslr_early_init': arch/arm64/kernel/kaslr.c:128:6: error: implicit declaration of function '__early_cpu_has_rndr'; did you mean '__early_pfn_to_nid'? [-Werror=implicit-function-declaration] if (__early_cpu_has_rndr()) { ^~~~~~~~~~~~~~~~~~~~ __early_pfn_to_nid arch/arm64/kernel/kaslr.c:131:7: error: implicit declaration of function '__arm64_rndr' [-Werror=implicit-function-declaration] if (__arm64_rndr(&raw)) ^~~~~~~~~~~~ The problem is that arch/archrandom.h is only included from linux/random.h if ARCH_RANDOM is enabled. If not, __arm64_rndr() and __early_cpu_has_rndr() are undeclared, causing the problem. Use arch_get_random_seed_long_early() instead of arm64 specific functions to solve the problem. Reported-by:

We just don't do that. "default y" is for things that are needed for compatibility (when an old feature is made unconditional), or for things that are basically part of the infrastructure of a platform. And it can possibly be used for questions that don't enable code on their own, but are used to enable or disable a whole slew of other questions. A new feature that people aren't using is never 'default y', unless it cures cancer or ends world hunger. Signed-off-by:

Pull iomap updates from Darrick Wong: "The most notable changes are: - iomap no longer invalidates the page cache when performing a direct read, since doing so is unnecessary and the old directio code doesn't do that either. - iomap embraced the use of returning ENOTBLK from a direct write to trigger falling back to a buffered write since ext4 already did this and btrfs wants it for their port. - iomap falls back to buffered writes if we're doing a direct write and the page cache invalidation after the flush fails; this was necessary to handle a corner case in the btrfs port. - Remove email virus scanner detritus that was accidentally included in yesterday's pull request. Clearly I need(ed) to update my git branch checker scripts. :(" * tag 'iomap-5.9-merge-5' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux: iomap: fall back to buffered writes for invalidation failures xfs: use ENOTBLK for direct I/O to buffered I/O fallback iomap: Only invalidate page cache pages on direct IO writes iomap: Make sure iomap_end is called after iomap_begin

This reverts commit 8bb9bf24. It seems the vmalloc page tables aren't always preallocated in all situations, because Jason Donenfeld reports an oops with this commit: BUG: unable to handle page fault for address: ffffe8ffffd00608 #PF: supervisor read access in kernel mode #PF: error_code(0x0000) - not-present page PGD 0 P4D 0 Oops: 0000 [#1] PREEMPT SMP CPU: 2 PID: 22 Comm: kworker/2:0 Not tainted 5.8.0+ #154 RIP: process_one_work+0x2c/0x2d0 Code: 41 56 41 55 41 54 55 48 89 f5 53 48 89 fb 48 83 ec 08 48 8b 06 4c 8b 67 40 49 89 c6 45 30 f6 a8 04 b8 00 00 00 00 4c 0f 44 f0 <49> 8b 46 08 44 8b a8 00 01 05 Call Trace: worker_thread+0x4b/0x3b0 ? rescuer_thread+0x360/0x360 kthread+0x116/0x140 ? __kthread_create_worker+0x110/0x110 ret_from_fork+0x1f/0x30 CR2: ffffe8ffffd00608 and that page fault address is right in that vmalloc space, and we clearly don't have a PGD/P4D entry for it. Looking at the "Code:" line, the actual fault seems to come from the 'pwq->wq' dereference at the top of the process_one_work() function: struct pool_workqueue *pwq = get_work_pwq(work); struct worker_pool *pool = worker->pool; bool cpu_intensive = pwq->wq->flags & WQ_CPU_INTENSIVE; so 'struct pool_workqueue *pwq' is the allocation that hasn't been synchronized across CPUs. Just revert for now, while Joerg figures out the cause. Reported-and-bisected-by:

During my code inspection I saw there is no implementation of a graceful shutdown for tcp. This patch will introduce a graceful shutdown for tcp connections. The shutdown is implemented synchronized as dlm_lowcomms_stop() is called to end all dlm communication. After shutdown is done, a lot of flush and closing functionality will be called. However I don't see a problem with that. The waitqueue for synchronize the shutdown has a timeout of 10 seconds, if timeout a force close will be exectued. Signed-off-by:

This patch changes the handling of reconnects. At first we only close the connection related to the communication failure. If we get a new connection for an already existing connection we close the existing connection and take the new one. This patch improves significantly the stability of tcp connections while running "tcpkill -9 -i $IFACE port 21064" while generating a lot of dlm messages e.g. on a gfs2 mount with many files. My test setup shows that a deadlock is "more" unlikely. Before this patch I wasn't able to get not a deadlock after 5 seconds. After this patch my observation is that it's more likely to survive after 5 seconds and more, but still a deadlock occurs after certain time. My guess is that there are still "segments" inside the tcp writequeue or retransmit queue which get dropped when receiving a tcp reset [1]. Hard to reproduce because the right message need to be inside these queues, which might even be in the 5 first seconds with this patch.

This patch doesn't close sockets when there is an invalid dlm message received. The connection will probably reconnect anyway so. To not close the connection will reduce the number of possible failtures. As we don't have a different strategy to react on such scenario just keep going the connection and ignore the message.
