2018-08-10cache policy: Check policy before returning a negative dirent.Nicolas Lacasse
The cache policy determines whether Lookup should return a negative dirent, or just ENOENT. This CL fixes one spot where we returned a negative dirent without first consulting the policy. PiperOrigin-RevId: 208280230 Change-Id: I8f963bbdb45a95a74ad0ecc1eef47eff2092d3a4

2018-08-10Enable checkpoint/restore in cases of UDS use.Brielle Broder
Previously, processes which used file-system Unix Domain Sockets could not be checkpoint-ed in runsc because the sockets were saved with their inode numbers which do not necessarily remain the same upon restore. Now, the sockets are also saved with their paths so that the new inodes can be determined for the sockets based on these paths after restoring. Tests for cases with UDS use are included. Test cleanup to come. PiperOrigin-RevId: 208268781 Change-Id: Ieaa5d5d9a64914ca105cae199fd8492710b1d7ec

2018-08-08Fix error handling for bad message sizes.Adin Scannell
The message size check is legitimate: the size must be negotiated, which relies on the fixed message limit up front. Sending a message larger than that indicates that the connection is out of sync and is considered a socket error (disconnect). Similarly, sending a size that is too small indicates that the stream is out-of-sync or invalid. PiperOrigin-RevId: 207996551 Change-Id: Icd8b513d5307e9d5953dbb957ee70ceea111098d

Add option to redirect packet back to netstack if it's destined to itself.

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
2018-08-08Fix data race in unix.BoundEndpoint.UnidirectionalConnect.Ian Gudger
Data race is: Read: (*connectionlessEndpoint).UnidirectionalConnect: writeQueue: e.receiver.(*queueReceiver).readQueue, Write: (*connectionlessEndpoint).Close: e.receiver = nil The problem is that (*connectionlessEndpoint).UnidirectionalConnect assumed that baseEndpoint.receiver is immutable which is explicitly not the case. Fixing this required two changes: 1. Add synchronization around access of baseEndpoint.receiver in (*connectionlessEndpoint).UnidirectionalConnect. 2. Check for baseEndpoint.receiver being nil in (*connectionlessEndpoint).UnidirectionalConnect. PiperOrigin-RevId: 207984402 Change-Id: Icddeeb43805e777fa3ef874329fa704891d14181

2018-08-07fs: Add new cache policy "remote_revalidate".Nicolas Lacasse
This CL adds a new cache-policy for gofer filesystems that uses the host page cache, but causes dirents to be reloaded on each Walk, and does not cache readdir results. This policy is useful when the remote filesystem may change out from underneath us, as any remote changes will be reflected on the next Walk. Importantly, this cache policy is only consistent if we do not use gVisor's internal page cache, since that page cache is tied to the Inode and may be thrown away upon Revalidation. This cache policy should only be used when the gofer supports donating host FDs, since then gVisor will make use of the host kernel page cache, which will be consistent for all open files in the gofer. In fact, a panic will be raised if a file is opened without a donated FD. PiperOrigin-RevId: 207752937 Change-Id: I233cb78b4695bbe00a4605ae64080a47629329b8

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.
