2020-02-18ring0/pagetables: fix typogVisor bot
PiperOrigin-RevId: 295770717
2020-01-27Update package locations.Adin Scannell
Because the abi will depend on the core types for marshalling (usermem, context, safemem, safecopy), these need to be flattened from the sentry directory. These packages contain no sentry-specific details. PiperOrigin-RevId: 291811289

2020-01-09New sync package.Ian Gudger
* Rename syncutil to sync. * Add aliases to sync types. * Replace existing usage of standard library sync package. This will make it easier to swap out synchronization primitives. For example, this will allow us to use primitives from github.com/sasha-s/go-deadlock to check for lock ordering violations. Updates #1472 PiperOrigin-RevId: 289033387

2019-09-12Remove go_test from go_stateify and go_marshalMichael Pratt
They are no-ops, so the standard rule works fine. PiperOrigin-RevId: 268776264

2018-10-23Track paths and provide a rename hook.Adin Scannell
This change also adds extensive testing to the p9 package via mocks. The sanity checks and type checks are moved from the gofer into the core package, where they can be more easily validated. PiperOrigin-RevId: 218296768 Change-Id: I4fc3c326e7bf1e0e140a454cbacbcc6fd617ab55

2018-08-22Add separate Recycle method for allocator.Adin Scannell
This improves debugging for pagetable-related issues. PiperOrigin-RevId: 209827795 Change-Id: I4cfa11664b0b52f26f6bc90a14c5bb106f01e038
2018-08-08Protect PCIDs with a mutex.Adin Scannell
Because the Drop method may be called across vCPUs, it is necessary to protect the PCID database with a mutex to prevent concurrent modification. The PCID is assigned prior to entersyscall, so it's safe to block. PiperOrigin-RevId: 207992864 Change-Id: I8b36d55106981f51e30dcf03e12886330bb79d67

2018-07-27stateify: support explicit annotation mode; convert refs and stack packages.Zhaozhong Ni
We have been unnecessarily creating too many savable types implicitly. PiperOrigin-RevId: 206334201 Change-Id: Idc5a3a14bfb7ee125c4f2bb2b1c53164e46f29a8
2018-06-11Make page tables split-safe.Adin Scannell
In order to minimize the likelihood of exit during page table modifications, make the full set of page table functions split-safe. This is not strictly necessary (and you may still incur splits due to allocations from the allocator pool) but should make retries a very rare occurance. PiperOrigin-RevId: 200146688 Change-Id: I8fa36aa16b807beda2f0b057be60038258e8d597
2018-06-06Split PCID implementation from page tables.Adin Scannell
Instead of associating a single PCID with each set of page tables (which will reach the maximum quickly), allow a dynamic pool for each vCPU. This is the same way that Linux operates. We also split management of PCIDs out of the page tables themselves for simplicity. PiperOrigin-RevId: 199585631 Change-Id: I42f3486ada3cb2a26f623c65ac279b473ae63201
2018-06-06Add allocator abstraction for page tables.Adin Scannell
In order to prevent possible garbage collection and reuse of page table pages prior to invalidation, introduce a former allocator abstraction that can ensure entries are held during a single traversal. This also cleans up the abstraction and splits it out of the machine itself. PiperOrigin-RevId: 199581636 Change-Id: I2257d5d7ffd9c36f9b7ecd42f769261baeaf115c
2018-06-01Move page tables lock into the address space.Adin Scannell
This is necessary to prevent races with invalidation. It is currently possible that page tables are garbage collected while paging caches refer to them. We must ensure that pages are held until caches can be invalidated. This is not achieved by this goal alone, but moving locking to outside the page tables themselves is a requisite.

2018-05-30Change ring0 & page tables arguments to structs.Adin Scannell
This is a refactor of ring0 and ring0/pagetables that changes from individual arguments to opts structures. This should involve no functional changes, but sets the stage for subsequent changes. PiperOrigin-RevId: 198627556 Change-Id: Id4460340f6a73f0c793cd879324398139cd58ae9
