2021-01-11Fix Go branch for arm64.Adin Scannell
This requires several changes: * Templates must preserve relevant tags. * Pagetables templates are split into two targets, each preserving tags. * The binary VDSO is similarly split into two targets, with some juggling. * The top level tools/go_branch.sh now does a crossbuild of ARM64 as well, and checks and merges the results of the two branches together. Fixes #5178 PiperOrigin-RevId: 351304330

2020-09-29Replace 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.

2020-08-20Consistent precondition formattingMichael 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

2020-01-27Update 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

2019-10-29Update symlink traversal limit when resolving interpreter path.Dean Deng
When execveat is called on an interpreter script, the symlink count for resolving the script path should be separate from the count for resolving the the corresponding interpreter. An ELOOP error should not occur if we do not hit the symlink limit along any individual path, even if the total number of symlinks encountered exceeds the limit.
