2021-06-22	[syserror] Add conversions to linuxerr with temporary Equals method.	Zach Koopmans
	Add Equals method to compare syserror and unix.Errno errors to linuxerr errors. This will facilitate removal of syserror definitions in a followup, and finding needed conversions from unix.Errno to linuxerr. PiperOrigin-RevId: 380909667
2021-06-13	Remove usermem dependency from marshal	Ian Lewis
	Both marshal and usermem are depended on by many packages and a dependency on marshal can often create circular dependencies. marshal should consider adding internal dependencies carefully moving forward. Fixes #6160 PiperOrigin-RevId: 379199882
2021-03-29	[syserror] Split usermem package	Zach Koopmans
	Split usermem package to help remove syserror dependency in go_marshal. New hostarch package contains code not dependent on syserror. PiperOrigin-RevId: 365651233
2021-03-03	[op] Replace syscall package usage with golang.org/x/sys/unix in pkg/.	Ayush Ranjan
	The syscall package has been deprecated in favor of golang.org/x/sys. Note that syscall is still used in the following places: - pkg/sentry/socket/hostinet/stack.go: some netlink related functionalities are not yet available in golang.org/x/sys. - syscall.Stat_t is still used in some places because os.FileInfo.Sys() still returns it and not unix.Stat_t. Updates #214 PiperOrigin-RevId: 360701387
2021-02-17	Add gohacks.Slice/StringHeader.	Jamie Liu
	See https://github.com/golang/go/issues/19367 for rationale. Note that the upstream decision arrived at in that thread, while useful for some of our use cases, doesn't account for all of our SliceHeader use cases (we often use SliceHeader to extract pointers from slices in a way that avoids bounds checking and/or handles nil slices correctly) and also doesn't exist yet.

2021-01-22	Define tcpip.Payloader in terms of io.Reader	Tamir Duberstein
	Fixes #1509. PiperOrigin-RevId: 353295589
2020-12-11	Remove existing nogo exceptions.	Adin Scannell

2020-09-29	Replace remaining uses of reflection-based marshalling.	Rahat Mahmood
	- Rewrite arch.Stack.{Push,Pop}. For the most part, stack now implements marshal.CopyContext and can be used as the target of marshal operations. Stack.Push had some extra logic for automatically null-terminating slices. This was only used for two specific types of slices, and is now handled explicitly. - Delete usermem.CopyObject{In,Out}. - Replace most remaining uses of the encoding/binary package with go-marshal. Most of these were using the binary package to compute the size of a struct, which go-marshal can directly replace. ~3 uses of the binary package remain. These aren't reasonably replaceable by go-marshal: for example one use is to construct the syscall trampoline for systrap. - Fill out remaining convenience wrappers in the primitive package.

2020-08-20	Consistent precondition formatting	Michael Pratt
	Our "Preconditions:" blocks are very useful to determine the input invariants, but they are bit inconsistent throughout the codebase, which makes them harder to read (particularly cases with 5+ conditions in a single paragraph). I've reformatted all of the cases to fit in simple rules: 1. Cases with a single condition are placed on a single line. 2. Cases with multiple conditions are placed in a bulleted list. This format has been added to the style guide. I've also mentioned "Postconditions:", though those are much less frequently used, and all uses already match this style. PiperOrigin-RevId: 327687465
2020-05-19	Implement mmap for host fs in vfs2.	Dean Deng
	In VFS1, both fs/host and fs/gofer used the same utils for host file mappings. Refactor parts of fsimpl/gofer to create similar utils to share with fsimpl/host (memory accounting code moved to fsutil, page rounding arithmetic moved to usermem). Updates #1476. PiperOrigin-RevId: 312345090
2020-04-13	Remove obsolete TODOs for b/38173783	Jon Budd
	The comments in the ticket indicate that this behavior is fine and that the ticket should be closed, so we shouldn't need pointers to the ticket. PiperOrigin-RevId: 306266071
2020-04-01	Fix 386 build tags	Michael Pratt
	The build tag for 32-bit x86 is 386, not i386. Updates #2298 PiperOrigin-RevId: 304206373
2020-02-25	Port most syscalls to VFS2.	Jamie Liu
	pipe and pipe2 aren't ported, pending a slight rework of pipe FDs for VFS2. mount and umount2 aren't ported out of temporary laziness. access and faccessat need additional FSImpl methods to implement properly, but are stubbed to prevent googletest from CHECK-failing. Other syscalls require additional plumbing. Updates #1623 PiperOrigin-RevId: 297188448
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
