Raven Scott b99da7bebc patch kex 2026-05-03 01:46:14 -04:00
Raven Scott baae7b3482 VFS readFile often returns Uint8Array; SFTP DATA and CHANNEL_DATA assumed 
Buffer.isBuffer or treated payloads as UTF-8, corrupting packets and risking
native aborts (bad_optional_access). Normalize ArrayBuffer views in
SFTP.prototype.data and Protocol channelData/channelExtData; align READ shim.

Also includes earlier SFTP hardening: REQUEST.READ/WRITE/FSETSTAT guards,
enqueueSftpReply(reqid) + FAILURE on handler error, CHANGELOG.

Raven Scott 0359129a72 - SFTP.js: validate handle/offset/len on REQUEST.READ; guard WRITE/FSETSTAT 
handle access like other handlers (avoid throwing before doFatalSFTPError).
- bare-openssh-sftp: enqueueSftpReply(reqid, fn) sends SSH_FX_FAILURE on
  handler throw/reject; defensive READ path (buffer/finite offsets).
- Document regression (bad_optional_access / -fno-exceptions) in comments;
  add packages/bare-os-openssh/CHANGELOG.md Unreleased entry.
