Scott Moreau 81a8ba9d0e server: Handle cut text messages of up to 10MB 2020-09-25 21:47:59 +00:00
Scott Moreau 783807c0b9 server: Fix possible crash on fragmented packet messages
The packets sent from the client especially for client cut text,
are typically sent in two packets, one for the message containing
the type and length and the other for the actual data. Sometimes
the first message is read but we still don't have the data yet.
We need to continue reading data to use the structure but this
revealed a bug. The client event handler was calling memmove()
with buffer_index as the size argument. This meant that it was
copying the wrong amount of data, resulting in garbage at the
end of the expected data. This patch fixes the problem by first
subtracting buffer_index from buffer_len and then moving buffer_len
worth of data, which is what was read into msg_buffer. The problem
possibly manifested itself with random crashes, after reading
random data.

Scott Moreau 6d29937e15 server: Add remaining support for simple copy/paste
- Add function to set callback for client_cut_text
- Add server_cut_text structure and function

This in conjunction with wayvnc #66 closes #4.

Stefan Agner 8f9c71bb33 fix below zero message count check
size_t is unsigned and hence can't be below zero, triggering this gcc
warning with gcc 10:
  warning: comparison of unsigned expression in ‘< 0’ is always false [-Wtype-limits]

It seems this if statement is meant to check if there are messages to
process (larger than 0). If there are no messages, we should jump out
early.

Stefan Agner a37eed4a4a remove fb_lock/unlock
The two functions have been removed from the external header file.
Remove them and the now unnecessary field is_locked.

Stefan Agner 8316994dfa use static for functions not used outside this compile unit
Add static for all functions only used inside the individual compile
units. This helps the compiler to potentially inline these functions.

This allows to use neatvnc as a Meson subproject in Weston which has
-Wmissing-prototypes enabled by default.

Andri Yngvason 77b866096d Redesign framebuffer update loop
Rendering may now only happen inside the rendering callback. The user is
also allowed to change out the entire buffer in the callback.

The callback is triggered by nvnc_damage_region(), nvnc_damage_whole()
and/or framebuffer update requests.

This fixes #26
