bb5a93a | Linus Torvalds | 05 July 2020, 19:50:20 UTC | x86/ldt: use "pr_info_once()" instead of open-coding it badly Using a mutex for "print this warning only once" is so overdesigned as to be actively offensive to my sensitive stomach. Just use "pr_info_once()" that already does this, although in a (harmlessly) racy manner that can in theory cause the message to be printed twice if more than one CPU races on that "is this the first time" test. [ If somebody really cares about that harmless data race (which sounds very unlikely indeed), that person can trivially fix printk_once() by using a simple atomic access, preferably with an optimistic non-atomic test first before even bothering to treat the pointless "make sure it is _really_ just once" case. A mutex is most definitely never the right primitive to use for something like this. ] Yes, this is a small and meaningless detail in a code path that hardly matters. But let's keep some code quality standards here, and not accept outrageously bad code.

fcec538 | Hauke Mehrtens | 02 July 2020, 22:53:34 UTC | MIPS: Add missing EHB in mtc0 -> mfc0 sequence for DSPen This resolves the hazard between the mtc0 in the change_c0_status() and the mfc0 in configure_exception_vector(). Without resolving this hazard configure_exception_vector() could read an old value and would restore this old value again. This would revert the changes change_c0_status() did. I checked this by printing out the read_c0_status() at the end of per_cpu_trap_init() and the ST0_MX is not set without this patch. The hazard is documented in the MIPS Architecture Reference Manual Vol. III: MIPS32/microMIPS32 Privileged Resource Architecture (MD00088), rev 6.03 table 8.1 which includes: Producer | Consumer | Hazard ----------|----------|---------------------------- mtc0 | mfc0 | any coprocessor 0 register I saw this hazard on an Atheros AR9344 rev 2 SoC with a MIPS 74Kc CPU. There the change_c0_status() function would activate the DSPen by setting ST0_MX in the c0_status register. This was reverted and then the system got a DSP exception when the DSP registers were saved in save_dsp() in the first process switch. The crash looks like this: [ 0.089999] Mount-cache hash table entries: 1024 (order: 0, 4096 bytes, linear) [ 0.097796] Mountpoint-cache hash table entries: 1024 (order: 0, 4096 bytes, linear) [ 0.107070] Kernel panic - not syncing: Unexpected DSP exception [ 0.113470] Rebooting in 1 seconds.. We saw this problem in OpenWrt only on the MIPS 74Kc based Atheros SoCs, not on the 24Kc based SoCs. We only saw it with kernel 5.4 not with kernel 4.19, in addition we had to use GCC 8.4 or 9.X, with GCC 8.3 it did not happen. In the kernel I bisected this problem to commit 9012d011660e ("compiler: allow all arches to enable CONFIG_OPTIMIZE_INLINING"), but when this was reverted it also happened after commit 172dcd935c34b ("MIPS: Always allocate exception vector for MIPSr2+"). Commit 0b24cae4d535 ("MIPS: Add missing EHB in mtc0 -> mfc0 sequence.") does similar changes to a different file. I am not sure if there are more places affected by this problem.

b7db41c | Jens Axboe | 04 July 2020, 14:55:50 UTC | io_uring: fix regression with always ignoring signals in io_cqring_wait() When switching to TWA_SIGNAL for task_work notifications, we also made any signal based condition in io_cqring_wait() return -ERESTARTSYS. This breaks applications that rely on using signals to abort someone waiting for events. Check if we have a signal pending because of queued task_work, and repeat the signal check once we've run the task_work. This provides a reliable way of telling the two apart.

For example, mm/hugetlb.c is trying to reserve per-numa cma for gigantic pages. But it can easily leak cma and make users confused when system has memoryless nodes. In case the system has 4 numa nodes, and only numa node0 has memory. if we set hugetlb_cma=4G in bootargs, mm/hugetlb.c will get 4 cma areas for 4 different numa nodes. since exact_nid=false in current code, all 4 numa nodes will get cma successfully from node0, but hugetlb_cma[1 to 3] will never be available to hugepage will only allocate memory from hugetlb_cma[0]. In case the system has 4 numa nodes, both numa node0&2 has memory, other nodes have no memory. if we set hugetlb_cma=4G in bootargs, mm/hugetlb.c will get 4 cma areas for 4 different numa nodes. since exact_nid=false in current code, all 4 numa nodes will get cma successfully from node0 or 2, but hugetlb_cma[1] and [3] will never be available to hugepage as mm/hugetlb.c will only allocate memory from hugetlb_cma[0] and hugetlb_cma[2]. This causes permanent leak of the cma areas which are supposed to be used by memoryless node. Of cource we can workaround the issue by letting mm/hugetlb.c scan all cma areas in alloc_gigantic_page() even node_mask includes node0 only. that means when node_mask includes node0 only, we can get page from hugetlb_cma[1] to hugetlb_cma[3]. But this will cause kernel crash in free_gigantic_page() while it wants to free page by: cma_release(hugetlb_cma[page_to_nid(page)], page, 1 << order) On the other hand, exact_nid=false won't consider numa distance, it might be not that useful to leverage cma areas on remote nodes. I feel it is much simpler to make exact_nid true to make everything clear. After that, memoryless nodes won't be able to reserve per-numa CMA from other nodes which have memory.

Due to the context in which hpage_nr_pages was called, it is unlikely to produce a user visible error. The routine with the incorrect call is only exercised in the case of hugetlb memory error or migration. In addition, this would need to be on an architecture which supports huge page sizes less than PMD_SIZE. And, the vma containing the huge page would also need to smaller than PMD_SIZE.

c860f8f | Bob Peterson | 25 June 2020, 19:42:17 UTC | gfs2: The freeze glock should never be frozen Before this patch, some gfs2 code locked the freeze glock with LM_FLAG_NOEXP (Do not freeze) flag, and some did not. We never want to freeze the freeze glock, so this patch makes it consistently use LM_FLAG_NOEXP always. Signed-off-by: Bob Peterson <rpeterso@redhat.com> | 03 July 2020, 10:05:35 UTC |
623ba66 | Bob Peterson | 25 June 2020, 18:30:52 UTC | gfs2: When freezing gfs2, use GL_EXACT and not GL_NOCACHE Before this patch, the freeze code in gfs2 specified GL_NOCACHE in several places. That's wrong because we always want to know the state of whether the file system is frozen. There was also a problem with freeze/thaw transitioning the glock from frozen (EX) to thawed (SH) because gfs2 will normally grant glocks in EX to processes that request it in SH mode, unless GL_EXACT is specified. Therefore, the freeze/thaw code, which tried to reacquire the glock in SH mode would get the glock in EX mode, and miss the transition from EX to SH. That made it think the thaw had completed normally, but since the glock was still cached in EX, other nodes could not freeze again. This patch removes the GL_NOCACHE flag to allow the freeze glock to be cached. It also adds the GL_EXACT flag so the glock is fully transitioned from EX to SH, thereby allowing future freeze operations.

b780cc6 | Bob Peterson | 25 June 2020, 18:30:18 UTC | gfs2: read-only mounts should grab the sd_freeze_gl glock Before this patch, only read-write mounts would grab the freeze glock in read-only mode, as part of gfs2_make_fs_rw. So the freeze glock was never initialized. That meant requests to freeze, which request the glock in EX, were granted without any state transition. That meant you could mount a gfs2 file system, which is currently frozen on a different cluster node, in read-only mode. This patch makes read-only mounts lock the freeze glock in SH mode, which will block for file systems that are frozen on another node.

541656d | Bob Peterson | 25 June 2020, 18:29:44 UTC | gfs2: freeze should work on read-only mounts Before this patch, function freeze_go_sync, called when promoting the freeze glock, was testing for the SDF_JOURNAL_LIVE superblock flag. That's only set for read-write mounts. Read-only mounts don't use a journal, so the bit is never set, so the freeze never happened. This patch removes the check for SDF_JOURNAL_LIVE for freeze requests but still checks it when deciding whether to flush a journal.

7542486 | Bob Peterson | 17 June 2020, 12:47:34 UTC | gfs2: eliminate GIF_ORDERED in favor of list_empty In several places, we used the GIF_ORDERED inode flag to determine if an inode was on the ordered writes list. However, since we always held the sd_ordered_lock spin_lock during the manipulation, we can just as easily check list_empty(&ip->i_ordered) instead. This allows us to keep more than one ordered writes list to make journal writing improvements. This patch eliminates GIF_ORDERED in favor of checking list_empty.

I put a few printouts in and saw that tpm_tis_spi_init() (specifically tpm_chip_register() in that function) was taking the lion's share of this time, though ~115 ms of the time was in cr50_print_fw_version(). Let's make a one-line change to prefer async probe for tpm_tis_spi. There's no reason we need to block other drivers from probing while we load. NOTES: * It's possible that other hardware runs through the init sequence faster than Cr50 and this isn't such a big problem for them. However, even if they are faster they are still doing _some_ transfers over a SPI bus so this should benefit everyone even if to a lesser extent. * It's possible that there are extra delays in the code that could be optimized out.

72d0556 | David Gibson | 19 June 2020, 03:30:40 UTC | tpm: ibmvtpm: Wait for ready buffer before probing for TPM2 attributes The tpm2_get_cc_attrs_tbl() call will result in TPM commands being issued, which will need the use of the internal command/response buffer. But, we're issuing this *before* we've waited to make sure that buffer is allocated. This can result in intermittent failures to probe if the hypervisor / TPM implementation doesn't respond quickly enough. I find it fails almost every time with an 8 vcpu guest under KVM with software emulated TPM. To fix it, just move the tpm2_get_cc_attrs_tlb() call after the existing code to wait for initialization, which will ensure the buffer is allocated.

eac9347 | Douglas Anderson | 28 May 2020, 22:19:30 UTC | tpm_tis_spi: Don't send anything during flow control During flow control we are just reading from the TPM, yet our spi_xfer has the tx_buf and rx_buf both non-NULL which means we're requesting a full duplex transfer. SPI is always somewhat of a full duplex protocol anyway and in theory the other side shouldn't really be looking at what we're sending it during flow control, but it's still a bit ugly to be sending some "random" data when we shouldn't. The default tpm_tis_spi_flow_control() tries to address this by setting 'phy->iobuf[0] = 0'. This partially avoids the problem of sending "random" data, but since our tx_buf and rx_buf both point to the same place I believe there is the potential of us sending the TPM's previous byte back to it if we hit the retry loop. Another flow control implementation, cr50_spi_flow_control(), doesn't address this at all. Let's clean this up and just make the tx_buf NULL before we call flow_control(). Not only does this ensure that we're not sending any "random" bytes but it also possibly could make the SPI controller behave in a slightly more optimal way. NOTE: no actual observed problems are fixed by this patch--it's was just made based on code inspection.

7862840 | James Bottomley | 28 May 2020, 18:10:57 UTC | tpm: Fix TIS locality timeout problems It has been reported that some TIS based TPMs are giving unexpected errors when using the O_NONBLOCK path of the TPM device. The problem is that some TPMs don't like it when you get and then relinquish a locality (as the tpm_try_get_ops()/tpm_put_ops() pair does) without sending a command. This currently happens all the time in the O_NONBLOCK write path. Fix this by moving the tpm_try_get_ops() further down the code to after the O_NONBLOCK determination is made. This is safe because the priv->buffer_mutex still protects the priv state being modified.

f7b93d4 | Ard Biesheuvel | 30 June 2020, 08:19:21 UTC | arm64/alternatives: use subsections for replacement sequences When building very large kernels, the logic that emits replacement sequences for alternatives fails when relative branches are present in the code that is emitted into the .altinstr_replacement section and patched in at the original site and fixed up. The reason is that the linker will insert veneers if relative branches go out of range, and due to the relative distance of the .altinstr_replacement from the .text section where its branch targets usually live, veneers may be emitted at the end of the .altinstr_replacement section, with the relative branches in the sequence pointed at the veneers instead of the actual target. The alternatives patching logic will attempt to fix up the branch to point to its original target, which will be the veneer in this case, but given that the patch site is likely to be far away as well, it will be out of range and so patching will fail. There are other cases where these veneers are problematic, e.g., when the target of the branch is in .text while the patch site is in .init.text, in which case putting the replacement sequence inside .text may not help either. So let's use subsections to emit the replacement code as closely as possible to the patch site, to ensure that veneers are only likely to be emitted if they are required at the patch site as well, in which case they will be in range for the replacement sequence both before and after it is transported to the patch site. This will prevent alternative sequences in non-init code from being released from memory after boot, but this is tolerable given that the entire section is only 512 KB on an allyesconfig build (which weighs in at 500+ MB for the entire Image). Also, note that modules today carry the replacement sequences in non-init sections as well, and any of those that target init code will be emitted into init sections after this change.
