2021-07-01[syserror] Update several syserror errors to linuxerr equivalents.Zach Koopmans

2021-06-30[syserror] Update syserror to linuxerr for EACCES, EBADF, and EPERM.Zach Koopmans
Update all instances of the above errors to the faster linuxerr implementation. With the temporary linuxerr.Equals(), no logical changes are made. PiperOrigin-RevId: 382306655

2021-06-29[syserror] Change syserror to linuxerr for E2BIG, EADDRINUSE, and EINVALZach Koopmans
Remove three syserror entries duplicated in linuxerr. Because of the linuxerr.Equals method, this is a mere change of return values from syserror to linuxerr definitions. Done with only these three errnos as CLs removing all grow to a significantly large size. PiperOrigin-RevId: 382173835

2020-11-03Make pipe min/max sizes match linux.Nicolas Lacasse
The default pipe size already matched linux, and is unchanged. Furthermore `atomicIOBytes` is made a proper constant (as it is in Linux). We were plumbing usermem.PageSize everywhere, so this is no functional change. PiperOrigin-RevId: 340497006

2020-10-13Don't read beyond EOF when inserting into sentry page cache.Jamie Liu
The sentry page cache stores file contents at page granularity; this is necessary for memory mappings. Thus file offset ranges passed to fsutil.FileRangeSet.Fill() must be page-aligned. If the read callback passed to Fill() returns (partial read, nil error) when reading up to EOF (which is the case for p9.ClientFile.ReadAt() since 9P's Rread cannot convey both a partial read and EOF), Fill() will re-invoke the read callback to try to read from EOF to the end of the containing page, which is harmless but needlessly expensive. Fix this by handling file size explicitly in fsutil.FileRangeSet.Fill(). PiperOrigin-RevId: 336934075

2020-08-25Return non-zero size for tmpfs statfs(2).Jamie Liu
This does not implement accepting or enforcing any size limit, which will be more complex and has performance implications; it just returns a fixed non-zero size. Updates #1936 PiperOrigin-RevId: 328428588

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

2020-01-16Plumb getting/setting xattrs through InodeOperations and 9p gofer interfaces.Dean Deng
There was a very bare get/setxattr in the InodeOperations interface. Add context.Context to both, size to getxattr, and flags to setxattr. Note that extended attributes are passed around as strings in this implementation, so size is automatically encoded into the value. Size is added in getxattr so that implementations can return ERANGE if a value is larger than can fit in the user-allocated buffer. This prevents us from unnecessarily passing around an arbitrarily large xattr when the user buffer is actually too small. Don't use the existing xattrwalk and xattrcreate messages and define our own, mainly for the sake of simplicity. Extended attributes will be implemented in future commits.

* 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.
