| | | | | | | | | | | | | | | | | | | | | | | | | | | | On certain corrupt gzip files, huft_build will set the error bit on the result pointer. If afterwards abort_unzip is called huft_free might run into a segmentation fault or an invalid pointer to free(p). In order to mitigate this, we check in huft_free if the error bit is set and clear it before the linked list is freed.

* | win32: implement symlink(2)Ron Yorston2021-02-121-11/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Provide an implementation of symlink(2). Calls to symlink(2) will fail in default Windows installations unless running with elevated privileges. Failure to create a symlink when extracting files from an archive is therefore treated as a non-fatal error. There are two ways to permit the creation of symlinks: - Edit security policy to give users the 'Create symbolic links' privilege. Unfortunately this doesn't work for users who are an Administrator. - Enable developer mode, which is available in later versions of Windows 10. The ability to create symlinks is not available in Windows XP or ReactOS.

* | libarchive: allow extraction of hard linksRon Yorston2021-01-192-7/+8
| | | | | | | | | | | | | | | | Allow create_or_remember_link() to create hardlinks. As a result tar and cpio can now extract hard links. Since unzip only supports symlinks it sees no improvement. As before, attempts to extract symlinks result in a warning.
