c0a3601 Benjamin Herrenschmidt 15 November 2016, 04:28:33 UTC powerpc/64: Fix setting of AIL in hypervisor mode Commit d3cbff1b5 "powerpc: Put exception configuration in a common place" broke the setting of the AIL bit (which enables taking exceptions with the MMU still on) on all processors, moving it incorrectly to a function called only on the boot CPU. This was correct for the guest case but not when running in hypervisor mode. This fixes it by partially reverting that commit, putting the setting back in cpu_ready_for_interrupts() Fixes: d3cbff1b5a90 ("powerpc: Put exception configuration in a common place") Cc: stable@vger.kernel.org # v4.8+ Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> 15 November 2016, 09:43:59 UTC

e6740ae Hugh Dickins 08 November 2016, 06:28:21 UTC powerpc: Fix exception vector build with 2.23 era binutils The changes to use gas sections for constructing the exception vectors causes a build break when using binutils 2.23: arch/powerpc/kernel/exceptions-64s.S:770: Error: operand out of range (0xffffffffffff8100 is not between 0x0000000000000000 and 0x000000000000ffff) And so on. Reported by Hugh with binutils-2.23.2-8.1.4.ppc64 from openSUSE 13.1 and also Naveen & Denis using 2.23.52.0.1-26.el7 from RHEL 7. Strangely binutils 2.22 (what I test with) is not affected. This is caused by the use of @l in LOAD_HANDLER(). The @l was only recently added in commit a24553dd02dc ("powerpc/pseries: Remove unnecessary syscall trampoline"). Luckily the gas section changes split out the LOAD_SYSCALL_HANDLER() macro, which means we actually *don't* need to use @l in LOAD_HANDLER() any more, only in LOAD_SYSCALL_HANDLER(). So drop the @l from LOAD_HANDLER().

f23ed16 Nicholas Piggin 02 November 2016, 06:57:01 UTC powerpc/64s: Fix system reset interrupt winkle wakeups Wakeups from winkle set the low bit of the HSPRG0 register, to distinguish it from other sleep states. This is also the PACA pointer. The system reset exception handler fails to mask this bit away before using this value before using it as the PACA pointer. Fix this by adding a new type of exception prolog macro where we already have the PACA set in r13, and have the system reset vector mask it out. The winkle wakeup handler will store the masked value back into HSPRG0.

fb479e4 Nicholas Piggin 13 October 2016, 02:17:14 UTC powerpc/64s: relocation, register save fixes for system reset interrupt This patch does a couple of things. First of all, powernv immediately explodes when running a relocated kernel, because the system reset exception for handling sleeps does not do correct relocated branches. Secondly, the sleep handling code trashes the condition and cfar registers, which we would like to preserve for debugging purposes (for non-sleep case exception). This patch changes the exception to use the standard format that saves registers before any tests or branches are made. It adds the test for idle-wakeup as an "extra" to break out of the normal exception path. Then it branches to a relocated idle handler that calls the various idle handling functions. After this patch, POWER8 CPU simulator now boots powernv kernel that is running at non-zero.

bd77c44 Aneesh Kumar K.V 24 October 2016, 03:20:43 UTC powerpc/mm/radix: Use tlbiel only if we ever ran on the current cpu Before this patch, we used tlbiel, if we ever ran only on this core. That was mostly derived from the nohash usage of the same. But is incorrect, the ISA 3.0 clarifies tlbiel such that: "All TLB entries that have all of the following properties are made invalid on the thread executing the tlbiel instruction" ie. tlbiel only invalidates TLB entries on the current thread. So if the mm has been used on any other thread (aka. cpu) then we must broadcast the invalidate. This bug could lead to invalid TLB entries if a program runs on multiple threads of a core. Hence use tlbiel, if we only ever ran on only the current cpu.

39715bf Valentin Rothberg 05 October 2016, 05:57:26 UTC powerpc/process: Fix CONFIG_ALIVEC typo in restore_tm_state() It should be ALTIVEC, not ALIVEC. Cyril explains: If a thread performs a transaction with altivec and then gets preempted for whatever reason, this bug may cause the kernel to not re-enable altivec when that thread runs again. This will result in an altivec unavailable fault, when that fault happens inside a user transaction the kernel has no choice but to enable altivec and doom the transaction. The result is that transactions using altivec may get aborted more often than they should. The difficulty in catching this with a selftest is my deliberate use of the word may above. Optimisations to avoid FPU/altivec/VSX faults mean that the kernel will always leave them on for 255 switches. This code prevents the kernel turning it off if it got to the 256th switch (and userspace was transactional).

09b7e37 Paul Mackerras 21 October 2016, 09:04:17 UTC powerpc/64: Fix race condition in setting lock bit in idle/wakeup code This fixes a race condition where one thread that is entering or leaving a power-saving state can inadvertently ignore the lock bit that was set by another thread, and potentially also clear it. The core_idle_lock_held function is called when the lock bit is seen to be set. It polls the lock bit until it is clear, then does a lwarx to load the word containing the lock bit and thread idle bits so it can be updated. However, it is possible that the value loaded with the lwarx has the lock bit set, even though an immediately preceding lwz loaded a value with the lock bit clear. If this happens then we go ahead and update the word despite the lock bit being set, and when called from pnv_enter_arch207_idle_mode, we will subsequently clear the lock bit. No identifiable misbehaviour has been attributed to this race. This fixes it by checking the lock bit in the value loaded by the lwarx. If it is set then we just go back and keep on polling.

56c4622 Paul Mackerras 21 October 2016, 09:03:05 UTC powerpc/64: Re-fix race condition between going idle and entering guest Commit 8117ac6a6c2f ("powerpc/powernv: Switch off MMU before entering nap/sleep/rvwinkle mode", 2014-12-10) fixed a race condition where one thread entering a KVM guest could switch the MMU context to the guest while another thread was still in host kernel context with the MMU on. That commit moved the point where a thread entering a power-saving mode set its kvm_hstate.hwthread_state field in its PACA to KVM_HWTHREAD_IN_IDLE from a point where the MMU was on to after the MMU had been switched off. That commit also added a comment explaining that we have to switch to real mode before setting hwthread_state to avoid this race. Nevertheless, commit 4eae2c9ae54a ("powerpc/powernv: Make pnv_powersave_common more generic", 2016-07-08) subsequently moved the setting of hwthread_state back to a point where the MMU is on, thus reintroducing the race, despite the comment saying that this should not be done being included in full in the context lines of the patch that did it. This fixes the race again and adds a bigger and shoutier comment explaining the potential race condition.

80f2393 Segher Boessenkool 06 October 2016, 13:42:19 UTC powerpc: Convert cmp to cmpd in idle enter sequence PowerPC's "cmp" instruction has four operands. Normally people write "cmpw" or "cmpd" for the second cmp operand 0 or 1. But, frequently people forget, and write "cmp" with just three operands. With older binutils this is silently accepted as if this was "cmpw", while often "cmpd" is wanted. With newer binutils GAS will complain about this for 64-bit code. For 32-bit code it still silently assumes "cmpw" is what is meant. In this instance the code comes directly from ISA v2.07, including the cmp, but cmpd is correct.

70b565b Vaibhav Jain 14 October 2016, 09:38:36 UTC cxl: Prevent adapter reset if an active context exists This patch prevents resetting the cxl adapter via sysfs in presence of one or more active cxl_context on it. This protects against an unrecoverable error caused by PSL owning a dirty cache line even after reset and host tries to touch the same cache line. In case a force reset of the card is required irrespective of any active contexts, the int value -1 can be stored in the 'reset' sysfs attribute of the card. The patch introduces a new atomic_t member named contexts_num inside struct cxl that holds the number of active context attached to the card , which is checked against '0' before proceeding with the reset. To prevent against a race condition where a context is activated just after reset check is performed, the contexts_num is atomically set to '-1' after reset-check to indicate that no more contexts can be activated on the card anymore. Before activating a context we atomically test if contexts_num is non-negative and if so, increment its value by one. In case the value of contexts_num is negative then it indicates that the card is about to be reset and context activation is error-ed out at that point.

89f39af Oleg Nesterov 26 September 2016, 16:07:48 UTC fs/super.c: fix race between freeze_super() and thaw_super() Change thaw_super() to check frozen != SB_FREEZE_COMPLETE rather than frozen == SB_UNFROZEN, otherwise it can race with freeze_super() which drops sb->s_umount after SB_FREEZE_WRITE to preserve the lock ordering. In this case thaw_super() will wrongly call s_op->unfreeze_fs() before it was actually frozen, and call sb_freeze_unlock() which leads to the unbalanced percpu_up_write().

3514de3 Steve French 14 October 2016, 00:06:23 UTC CIFS: Retrieve uid and gid from special sid if enabled New mount option "idsfromsid" indicates to cifs.ko that it should try to retrieve the uid and gid owner fields from special sids. This patch adds the code to parse the owner sids in the ACL to see if they match, and if so populate the uid and/or gid from them. This is faster than upcalling for them and asking winbind, and is a fairly common case, and is also helpful when cifs.upcall and idmapping is not configured.

35a891b Linus Torvalds 14 October 2016, 03:28:22 UTC Merge tag 'xfs-reflink-for-linus-4.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/dgc/linux-xfs < XFS has gained super CoW powers! > ---------------------------------- \ ^__^ \ (oo)\_______ (__)\ )\/\ ||----w | || || Pull XFS support for shared data extents from Dave Chinner: "This is the second part of the XFS updates for this merge cycle. This pullreq contains the new shared data extents feature for XFS. Given the complexity and size of this change I am expecting - like the addition of reverse mapping last cycle - that there will be some follow-up bug fixes and cleanups around the -rc3 stage for issues that I'm sure will show up once the code hits a wider userbase. What it is: At the most basic level we are simply adding shared data extents to XFS - i.e. a single extent on disk can now have multiple owners. To do this we have to add new on-disk features to both track the shared extents and the number of times they've been shared. This is done by the new "refcount" btree that sits in every allocation group. When we share or unshare an extent, this tree gets updated. Along with this new tree, the reverse mapping tree needs to be updated to track each owner or a shared extent. This also needs to be updated ever share/unshare operation. These interactions at extent allocation and freeing time have complex ordering and recovery constraints, so there's a significant amount of new intent-based transaction code to ensure that operations are performed atomically from both the runtime and integrity/crash recovery perspectives. We also need to break sharing when writes hit a shared extent - this is where the new copy-on-write implementation comes in. We allocate new storage and copy the original data along with the overwrite data into the new location. We only do this for data as we don't share metadata at all - each inode has it's own metadata that tracks the shared data extents, the extents undergoing CoW and it's own private extents. Of course, being XFS, nothing is simple - we use delayed allocation for CoW similar to how we use it for normal writes. ENOSPC is a significant issue here - we build on the reservation code added in 4.8-rc1 with the reverse mapping feature to ensure we don't get spurious ENOSPC issues part way through a CoW operation. These mechanisms also help minimise fragmentation due to repeated CoW operations. To further reduce fragmentation overhead, we've also introduced a CoW extent size hint, which indicates how large a region we should allocate when we execute a CoW operation. With all this functionality in place, we can hook up .copy_file_range, .clone_file_range and .dedupe_file_range and we gain all the capabilities of reflink and other vfs provided functionality that enable manipulation to shared extents. We also added a fallocate mode that explicitly unshares a range of a file, which we implemented as an explicit CoW of all the shared extents in a file. As such, it's a huge chunk of new functionality with new on-disk format features and internal infrastructure. It warns at mount time as an experimental feature and that it may eat data (as we do with all new on-disk features until they stabilise). We have not released userspace suport for it yet - userspace support currently requires download from Darrick's xfsprogs repo and build from source, so the access to this feature is really developer/tester only at this point. Initial userspace support will be released at the same time the kernel with this code in it is released. The new code causes 5-6 new failures with xfstests - these aren't serious functional failures but things the output of tests changing slightly due to perturbations in layouts, space usage, etc. OTOH, we've added 150+ new tests to xfstests that specifically exercise this new functionality so it's got far better test coverage than any functionality we've previously added to XFS. Darrick has done a pretty amazing job getting us to this stage, and special mention also needs to go to Christoph (review, testing, improvements and bug fixes) and Brian (caught several intricate bugs during review) for the effort they've also put in. Summary: - unshare range (FALLOC_FL_UNSHARE) support for fallocate - copy-on-write extent size hints (FS_XFLAG_COWEXTSIZE) for fsxattr interface - shared extent support for XFS - copy-on-write support for shared extents - copy_file_range support - clone_file_range support (implements reflink) - dedupe_file_range support - defrag support for reverse mapping enabled filesystems" * tag 'xfs-reflink-for-linus-4.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/dgc/linux-xfs: (71 commits) xfs: convert COW blocks to real blocks before unwritten extent conversion xfs: rework refcount cow recovery error handling xfs: clear reflink flag if setting realtime flag xfs: fix error initialization xfs: fix label inaccuracies xfs: remove isize check from unshare operation xfs: reduce stack usage of _reflink_clear_inode_flag xfs: check inode reflink flag before calling reflink functions xfs: implement swapext for rmap filesystems xfs: refactor swapext code xfs: various swapext cleanups xfs: recognize the reflink feature bit xfs: simulate per-AG reservations being critically low xfs: don't mix reflink and DAX mode for now xfs: check for invalid inode reflink flags xfs: set a default CoW extent size of 32 blocks xfs: convert unwritten status of reverse mappings for shared files xfs: use interval query for rmap alloc operations on shared files xfs: add shared rmap map/unmap/convert log item types xfs: increase log reservations for reflink ... 14 October 2016, 03:28:22 UTC

3c293f4 Andrew Lunn 12 October 2016, 20:14:53 UTC net: phy: Trigger state machine on state change and not polling. The phy_start() is used to indicate the PHY is now ready to do its work. The state is changed, normally to PHY_UP which means that both the MAC and the PHY are ready. If the phy driver is using polling, when the next poll happens, the state machine notices the PHY is now in PHY_UP, and kicks off auto-negotiation, if needed. If however, the PHY is using interrupts, there is no polling. The phy is stuck in PHY_UP until the next interrupt comes along. And there is no reason for the PHY to interrupt. Have phy_start() schedule the state machine to run, which both speeds up the polling use case, and makes the interrupt use case actually work. This problems exists whenever there is a state change which will not cause an interrupt. Trigger the state machine in these cases, e.g. phy_error().
