2020-08-04Inline gofer.regularFileFD.pwriteLockedFabricio Voznika
Go compiler barely inlines anything, so inline by hand pwriteLocked since it's called from a single place. PiperOrigin-RevId: 324937734

2020-08-04Error if dup'ing stdio FDs will clobber another FDFabricio Voznika
The loader dup's stdio FD into stable FD's starting at a fixed number. During tests, it's possible that the target FD is already in use. Added check to error early so it's easier to debug failures. Also bumped up the starting FD number to prevent collisions. PiperOrigin-RevId: 324917299
2020-08-04Use 1 fragmentation component per IP stackGhanan Gowripalan
This will help manage memory consumption by IP reassembly when receiving IP fragments on multiple network endpoints. Previously, each endpoint would cap memory consumption at 4MB, but with this change, each IP stack will cap memory consumption at 4MB. No behaviour changes. PiperOrigin-RevId: 324913904
2020-08-04Add reference counting utility to VFS2.Dean Deng
The utility has several differences from the VFS1 equivalent: - There are no weak references, which have a significant overhead - In order to print useful debug messages with the type of the reference- counted object, we use a generic Refs object with the owner type as a template parameter. In vfs1, this was accomplished by storing a type name and caller stack directly in the ref count (as in vfs1), which increases the struct size by 6x. (Note that the caller stack was needed because fs types like Dirent were shared by all fs implementations; in vfs2, each impl has its own data structures, so this is no longer necessary.) As an example, the utility is added to tmpfs.inode. Updates #1486. PiperOrigin-RevId: 324906582

2020-08-04Add shim documentation to the website.Ian Lewis
Add three new doc pages to the website. - A containerd quick start covering containerd 1.2. This is limited to shim v2 and runtime class as the docs would get too complicated explaining all the combinations that are possible. We want folks to use shim v2 and runtime class anyway. - An advanced configuration page. This covers containerd and containerd-shim-runsc-v1's configuration options. - A page for old versions (i.e. containerd 1.1). Notes that this is deprecated and supported on a best-effort basis.

2020-08-03Add support for a reverse HTTPD test.Bhasker Hariharan
This change adds a new reverse HTTP test where the HTTPD server runs in a native container but the client runs inside gVisor. It allows us to test download performance under varying levels of concurrency. Also tweaks the concurrent request numbers to test for high levels of concurrency. PiperOrigin-RevId: 324651203

Before kernel version 4.16-rc6, fuse mount is protected by capable(CAP_SYS_ADMIN). After this version, it uses ns_capable(CAP_SYS_ADMIN) to protect. Before the 4.16 kernel, it was not allowed to mount fuse file systems without the global CAP_SYS_ADMIN. Fixes #3360

2020-07-31[runtime tests] Enhance java runtime test.Ayush Ranjan
- Added a bunch of helpful options which help in speeding up the test and providing useful output. - Unexcluded passing tests and updated bugs. Excluded tests which were failing. - Increased the batch size for java tests so that we can take advantage of the shared JVMs. The running time of the tests decreased from 3+ hours (I don't know the exact running time because this test has always timed out after 3 hours) to 1 hour 15 minutes. We can reliably run this a CI kokoro job. PiperOrigin-RevId: 324301503

2020-07-30Port nginx and move parsers to own package.Zach Koopmans
This change: - Ports the nginx benchmark. - Switches the Httpd benchmark to use 'hey' as a client. - Moves all parsers to their own package 'tools'. Parsers are moved to their own package because 1) parsing output of a command is often dependent on the format of the command (e.g. 'fio --json'), 2) to enable easier reuse, and 3) clean up and simplify actual running benchmarks (no TestParser functions and ugly sample output in benchmark files).

2020-07-30Call lseek(0, SEEK_CUR) unconditionally in runsc fsgofer's Readdir(offset=0).Jamie Liu
9P2000.L is silent as to how readdir RPCs interact with directory mutation. The most performant option is for Treaddir with offset=0 to restart iteration, avoiding needing to walk+open+clunk a new directory fid between invocations of getdents64(2), and the VFS2 gofer client assumes this is the case. Make this actually true for the runsc fsgofer. Fixes #3344, #3345, #3355 PiperOrigin-RevId: 324090384
2020-07-30Revert change to default buffer size.Bhasker Hariharan
In https://github.com/google/gvisor/commit/ca6bded95dbce07f9683904b4b768dfc2d4a09b2 we reduced the default buffer size to 32KB. This mostly works fine except at high throughput where we hit zero window very quickly and the TCP receive buffer moderation is not able to grow the window. This can be seen in the benchmarks where with a 32KB buffer and 100 connections downloading a 10MB file we get about 30 requests/s vs the 1MB buffer gives us about 53 requests/s. A proper fix requires a few changes to when we send a zero window as well as when we decide to send a zero window update. Today we consider available space below 1MSS as zero and send an update when it crosses 1MSS of available space. This is way too low and results in the window staying very small once we hit a zero window condition as we keep sending updates with size barely over 1MSS. Linux and BSD are smarter about this and use different thresholds. We should separately update our logic to match linux or BSD so that we don't send window updates that are really tiny or wait until we drop below 1MSS to advertise a zero window.
