2020-02-07	Support listxattr and removexattr syscalls.	Dean Deng
	Note that these are only implemented for tmpfs, and other impls will still return EOPNOTSUPP. PiperOrigin-RevId: 293899385
2020-02-05	Disable get/set xattrs until list/remove exist too.	Nicolas Lacasse
	PiperOrigin-RevId: 293411655
2020-01-27	Update 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
2020-01-21	Add syscalls for lgetxattr, fgetxattr, lsetxattr, and fsetxattr.	Dean Deng
	Note that these simply will use the same logic as getxattr and setxattr, which is not yet implemented for most filesystems. PiperOrigin-RevId: 290800960
2020-01-17	Enable stat syscall support on arm64.	Haibo Xu
	x86 and arm64 use a different stat struct in Linux kernel, so the stat() syscall implementation has to handle the file stat data separately.

2020-01-16	Plumb 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.

2020-01-06	Implement rseq(2)	Michael Pratt
	PiperOrigin-RevId: 288342928
2019-12-16	Implement checks for get/setxattr at the syscall layer.	Dean Deng
	Add checks for input arguments, file type, permissions, etc. that match the Linux implementation. A call to get/setxattr that passes all the checks will still currently return EOPNOTSUPP. Actual support will be added in following commits. Only allow user.* extended attributes for the time being. PiperOrigin-RevId: 285835159
2019-12-10	Add all upstream syscalls to tables	Michael Pratt
	Package strace is missing some syscalls we actually implement (e.g., getrandom). We also see newer syscalls sometimes (e.g., membarrier) that would be handy to have formatted. Let's go ahead and add all syscalls in the latest upstream release (v5.4), even though we only intend to implement v4.4. None of them are implemented, just included as placeholders.

2019-12-09	Redirect TODOs to gvisor.dev	Fabricio Voznika
	PiperOrigin-RevId: 284606233
2019-11-26	Mark execveat as supported for linux64_arm64.	Dean Deng
	PiperOrigin-RevId: 282667122
2019-11-04	Update membarrier bug	Michael Pratt
	Updates #267 PiperOrigin-RevId: 278402684
2019-10-22	Update const names to be Go style.	Ian Lewis
	PiperOrigin-RevId: 276165962
2019-10-16	Fix syscall changes lost in rebase	Michael Pratt
	These syscalls were changed in the amd64 file around the time the arm64 PR was sent out, so their changes got lost. Updates #63 PiperOrigin-RevId: 275114194
2019-10-07	Merge pull request #753 from lubinszARM:pr_syscall_linux	gVisor bot
	PiperOrigin-RevId: 273364848
2019-09-18	enable syscalls/linux to support arm64	Bin Lu
