When used with a FreeRDP client on Linux, a file copy operation from
the clipboard detects end-of-file by a read returning 0 bytes. This is
currently marked as an error.
It is assumed that mstsc.exe detects end-of-file in another way, which
is why this has not been found before.
The routine clipboard_get_files() parses a potentially long string,
and copies portions of it into a temporary buffer. This buffer is then
passed to clipboard_get_file() as pointer + length;
The buffer is inadequately sized for very long filenames which may
approach XFS_MAXFILENAMELEN in length. This can cause chansrv to fail
when the user copies such filenames.
It turns out the buffer is unnecessary, as the filenames can be
passed directly into clipboard_get_file() from the source string,
using pointer + length. This avoids the length limitation entirely.
The limit of 256 characters for clipboard files is limiting for
many Asian locales, particularly as '%xx' notation is used to
communicate bytes with bit 7 set.
Rename g_file_open() to g_file_open_rw(), and add a new g_file_open_ro()
call that wraps the common g_file_open_ex(file, 1, 0, 0, 0) idiom. This
will make the file access mode more explicit in the code.
Change all calls to g_file_open() to the _ro() or _rw() variant as
appropriate, and replace g_file_open_ex(file, 1, 0, 0, 0) with the _ro()
call.
Lastly, add tests for the two new calls to test_os_calls.c (code
courteously provided by matt335672).
This commit adds:
* replace multiple logging macros with LOG and LOG_DEVEL
* logging configuration for chanserv
* logging configuration for console output
* logging configuration for per file or method log level filtering for
debug builds
* file, line, and method name in log message for debug builds
because 1st argument to clipboard_get_file() is given as URL encoded.
Decoding only filename is incomplete.
Without this fix, clipboard file doesn't work in case pathname
contains non-ASCII characters or non-alphanumeric ASCII characters.
When xfuse_create_file_in_xrdp_fs is failed, it returns NULL.
Without this fix, xinode->size causes SEGV, so implementation is changed
to return -1 and check the return value in caller.
o basic drive redirection is working
o functions currently supported: open:
read, write, create, get/set attribute
o requires latest NeutrinoRDP to work
o note: clipboard is broken because of the move from
linked lists to inodes in the FUSE code
