[PATCH] ext4: Fix checksum errors with indexed dirs

by Jan Kara

DIR_INDEX has been introduced as a compat ext4 feature. That means that even kernels / tools that don't understand the feature may modify the filesystem. This works because for kernels not understanding indexed dir format, internal htree nodes appear just as empty directory entries. Index dir aware kernels then check the htree structure is still consistent before using the data. This all worked reasonably well until metadata checksums were introduced. The problem is that these effectively made DIR_INDEX only ro-compatible because internal htree nodes store checksums in a different place than normal directory blocks. Thus any modification ignorant to DIR_INDEX (or just clearing EXT4_INDEX_FL from the inode) will effectively cause checksum mismatch and trigger kernel errors. So we have to be more careful when dealing with indexed directories on filesystems with checksumming enabled. 1) We just disallow loading and directory inodes with EXT4_INDEX_FL when DIR_INDEX is not enabled. This is harsh but it should be very rare (it means someone disabled DIR_INDEX on existing filesystem and didn't run e2fsck), e2fsck can fix the problem, and we don't want to answer the difficult question: "Should we rather corrupt the directory more or should we ignore that DIR_INDEX feature is not set?" 2) When we find out htree structure is corrupted (but the filesystem and the directory should in support htrees), we continue just ignoring htree information for reading but we refuse to add new entries to the directory to avoid corrupting it more.

[PATCH] x86/mpx: fix recursive munmap() corruption

by Dave Hansen

This is a bit of a mess, to put it mildly. But, it's a bug that seems to have gone unticked up to now, probably because nobody uses MPX. The other alternative to this fix is to just deprecate MPX, even in -stable kernels. MPX has the arch_unmap() hook inside of munmap() because MPX uses bounds tables that protect other areas of memory. When memory is unmapped, there is also a need to unmap the MPX bounds tables. Barring this, unused bounds tables can eat 80% of the address space. But, the recursive do_munmap() that gets called vi arch_unmap() wreaks havoc with __do_munmap()'s state. It can result in freeing populated page tables, accessing bogus VMA state, double-freed VMAs and more. To fix this, call arch_unmap() before __do_unmap() has a chance to do anything meaningful. Also, remove the 'vma' argument and force the MPX code to do its own, independent VMA lookup. For the common success case this is functionally identical to what was there before. For the munmap() failure case, it's possible that some MPX tables will be zapped for memory that continues to be in use. But, this is an extraordinarily unlikely scenario and the harm would be that MPX provides no protection since the bounds table got reset (zeroed). I can't imagine anyone doing this: ptr = mmap(); // use ptr ret = munmap(ptr); if (ret) // oh, there was an error, I'll // keep using ptr. Because if you're doing munmap(), you are *done* with the memory. There's probably no good data in there _anyway_. This passes the original reproducer from Richard Biener as well as the existing mpx selftests/. ==== The long story: munmap() has a couple of pieces: 1. Find the affected VMA(s) 2. Split the start/end one(s) if neceesary 3. Pull the VMAs out of the rbtree 4. Actually zap the memory via unmap_region(), including freeing page tables (or queueing them to be freed). 5. Fixup some of the accounting (like fput()) and actually free the VMA itself. I decided to put the arch_unmap() call right afer #3. This was *just* before mmap_sem looked like it might get downgraded (it won't in this context), but it looked right. It wasn't. Richard Biener reported a test that shows this in dmesg: [1216548.787498] BUG: Bad rss-counter state mm:0000000017ce560b idx:1 val:551 [1216548.787500] BUG: non-zero pgtables_bytes on freeing mm: 24576 What triggered this was the recursive do_munmap() called via arch_unmap(). It was freeing page tables that has not been properly zapped. But, the problem was bigger than this. For one, arch_unmap() can free VMAs. But, the calling __do_munmap() has variables that *point* to VMAs and obviously can't handle them just getting freed while the pointer is still valid. I tried a couple of things here. First, I tried to fix the page table freeing problem in isolation, but I then found the VMA issue. I also tried having the MPX code return a flag if it modified the rbtree which would force __do_munmap() to re-walk to restart. That spiralled out of control in complexity pretty fast. Just moving arch_unmap() and accepting that the bonkers failure case might eat some bounds tables seems like the simplest viable fix.

[PATCH v2] pinctrl: cherryview: Ensure _REG(ACPI_ADR_SPACE_GPIO, 1) gets called

by Hans de Goede

On Cherry Trail devices there are 2 possible ACPI OpRegions for accessing GPIOs. The standard GeneralPurposeIo OpRegion and the Cherry Trail specific UserDefined 0x9X OpRegions. Having 2 different types of OpRegions leads to potential issues with checks for OpRegion availability, or in other words checks if _REG has been called for the OpRegion which the ACPI code wants to use. The ACPICA core does not call _REG on an ACPI node which does not define an OpRegion matching the type being registered; and the reference design DSDT, from which most Cherry Trail DSDTs are derived, does not define GeneralPurposeIo, nor UserDefined(0x93) OpRegions for the GPO2 (UID 3) device, because no pins were assigned ACPI controlled functions in the reference design. Together this leads to the perfect storm, at least on the Cherry Trail based Medion Akayo E1239T. This design does use a GPO2 pin from its ACPI code and has added the Cherry Trail specific UserDefined(0x93) opregion to its GPO2 ACPI node to access this pin. But it uses a has _REG been called availability check for the standard GeneralPurposeIo OpRegion. This clearly is a bug in the DSDT, but this does work under Windows. This issue leads to the intel_vbtn driver reporting the device always being in tablet-mode at boot, even if it is in laptop mode. Which in turn causes userspace to ignore touchpad events. So iow this issues causes the touchpad to not work at boot. Since the bug in the DSDT stems from the confusion of having 2 different OpRegion types for accessing GPIOs on Cherry Trail devices, I believe that this is best fixed inside the Cherryview pinctrl driver. This commit adds a workaround to the Cherryview pinctrl driver so that the DSDT's expectations of _REG always getting called for the GeneralPurposeIo OpRegion are met.

The _mcsafe variants don’t just avoid the REP mess — they also tell the kernel that this particular access is recoverable via extable. With a regular memory access, the CPU may not explode, but do_machine_check() will, at very best, OOPS, and even that requires a certain degree of optimism. A panic is more likely.

[PATCH] drm: avoid spurious EBUSY due to nonblocking atomic modesets

by Daniel Vetter

When doing an atomic modeset with ALLOW_MODESET drivers are allowed to pull in arbitrary other resources, including CRTCs (e.g. when reconfiguring global resources). But in nonblocking mode userspace has then no idea this happened, which can lead to spurious EBUSY calls, both: - when that other CRTC is currently busy doing a page_flip the ALLOW_MODESET commit can fail with an EBUSY - on the other CRTC a normal atomic flip can fail with EBUSY because of the additional commit inserted by the kernel without userspace's knowledge For blocking commits this isn't a problem, because everyone else will just block until all the CRTC are reconfigured. Only thing userspace can notice is the dropped frames without any reason for why frames got dropped. Consensus is that we need new uapi to handle this properly, but no one has any idea what exactly the new uapi should look like. As a stop-gap plug this problem by demoting nonblocking commits which might cause issues by including CRTCs not in the original request to blocking commits. v2: Add comments and a WARN_ON to enforce this only when allowed - we don't want to silently convert page flips into blocking plane updates just because the driver is buggy.

[PATCH] cxl: Rework error message for incompatible slots

by Frederic Barrat

Improve the error message shown if a capi adapter is plugged on a capi-incompatible slot directly under the PHB (no intermediate switch).
