2018-07-26Don't copy-up extended attributes that specifically configure a lower overlay.Nicolas Lacasse
When copying-up files from a lower fs to an upper, we also copy the extended attributes on the file. If there is a (nested) overlay inside the lower, some of these extended attributes configure the lower overlay, and should not be copied-up to the upper. In particular, whiteout attributes in the lower fs overlay should not be copied-up, since the upper fs may actually contain the file.

2018-07-25runsc: Fix "exec" command when called without --pid-file.Nicolas Lacasse
When "exec" command is called without the "--detach" flag, we spawn a second "exec" command and wait for that one to start. We use the pid file passed in --pid-file to detect when this second command has started running. However if "exec" is called with no --pid-file flag, this system breaks down, as we don't have a pid file to wait for. This CL ensures that the second instance of the "exec" command always writes a pid-file, so the wait is successful. PiperOrigin-RevId: 206002403 Change-Id: If9f2be31eb6e831734b1b833f25054ec71ab94a6

2018-07-19fs: Pass context to Revalidate() function.Nicolas Lacasse
The current revalidation logic is very simple and does not do much introspection of the dirent being revalidated (other than looking at the type of file). Fancier revalidation logic is coming soon, and we need to be able to look at the cached and uncached attributes of a given dirent, and we need a context to perform some of these operations.

2018-07-19ConfigureMMap on an overlay file delegates to the upper if there is no lower.Nicolas Lacasse
In the general case with an overlay, all mmap calls must go through the overlay, because in the event of a copy-up, the overlay needs to invalidate any previously-created mappings. If there if no lower file, however, there will never be a copy-up, so the overlay can delegate directly to the upper file in that case. This also allows us to correctly mmap /dev/zero when it is in an overlay. This file has special semantics which the overlay does not know about. In particular, it does not implement Mappable(), which (in the general case) the overlay uses to detect if a file is mappable or not.

With musl libc when these entries are missing from the aux vector it's forcing libc.secure (effectively AT_SECURE).

2018-07-18Moved restore code out of create and made to be called after create.Justine Olshan
Docker expects containers to be created before they are restored. However, gVisor restoring requires specificactions regarding the kernel and the file system. These actions were originally in booting the sandbox. Now setting up the file system is deferred until a call to a call to runsc start. In the restore case, the kernel is destroyed and a new kernel is created in the same process, as we need the same process for Docker. These changes required careful execution of concurrent processes which required the use of a channel. Full docker integration still needs the ability to restore into the same container.

2018-07-18Fix lock-ordering violation in Create by logging BaseName instead of FullName.Nicolas Lacasse
Dirent.FullName takes the global renameMu, but can be called during Create, which itself takes dirent.mu and dirent.dirMu, which is a lock-order violation: Dirent.Create d.dirMu.Lock d.mu.Lock Inode.Create gofer.inodeOperations.Create gofer.NewFile Dirent.FullName d.renameMu.RLock We only use the FullName here for logging, and in this case we can get by with logging only the BaseName. A `BaseName` method was added to Dirent, which simply returns the name, taking d.parent.mu as required. In the Create pathway, we can't call d.BaseName() because taking d.parent.mu after d.mu violates the lock order. But we already know the base name of the file we just created, so that's OK. In the Open/GetFile pathway, we are free to call d.BaseName() because the other dirent locks are not held. PiperOrigin-RevId: 205112278 Change-Id: Ib45c734081aecc9b225249a65fa8093eb4995f10
2018-07-17Merge FileMem.usage in IncRefMichael Pratt
Per the doc, usage must be kept maximally merged. Beyond that, it is simply a good idea to keep fragmentation in usage to a minimum. The glibc malloc allocator allocates one page at a time, potentially causing lots of fragmentation. However, those pages are likely to have the same number of references, often making it possible to merge ranges. PiperOrigin-RevId: 204960339 Change-Id: I03a050cf771c29a4f05b36eaf75b1a09c9465e14

2018-07-16Start allocation and reclaim scans only where they may find a matchMichael Pratt
If usageSet is heavily fragmented, findUnallocatedRange and findReclaimable can spend excessive cycles linearly scanning the set for unallocated/free pages. Improve common cases by beginning the scan only at the first page that could possibly contain an unallocated/free page. This metadata only guarantees that there is no lower unallocated/free page, but a scan may still be required (especially for multi-page allocations). That said, this heuristic can still provide significant performance improvements for certain applications. PiperOrigin-RevId: 204841833 Change-Id: Ic41ad33bf9537ecd673a6f5852ab353bf63ea1e6
