* call: Fix buffer overflow.Ralf Baechle2017-07-261-1/+1
| | | | | | | | | | | | | | | | | | | | | When sending files of 1GB or larger, size_buffer was not large enough to hold the number including a trailing \0. This also fixes the following warning: gcc -DHAVE_CONFIG_H -I. -I.. -g -O2 -Wall -MT yapp.o -MD -MP -MF .deps/yapp.Tpo -c -o yapp.o yapp.c yapp.c: In function ‘yapp_upload_data’: yapp.c:200:24: warning: ‘%ld’ directive writing between 1 and 11 bytes into a region of size 10 [-Wformat-overflow=] sprintf(size_buffer, "%ld", length); ^~~ yapp.c:200:23: note: directive argument in the range [-2147483648, 2147483647] sprintf(size_buffer, "%ld", length); ^~~~~ yapp.c:200:2: note: ‘sprintf’ output between 2 and 12 bytes into a destination of size 10 sprintf(size_buffer, "%ld", length); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

* UTF-8 support for call.Thomas Osterried2016-02-112-278/+769
| | | | | | | | | | | | | | | | | | | | | Patch by Cathryn Mataga. 1. Now supports UTF8 or IBM850 as the encoding style over AX25. 1a. Attention was paid to make sure that wide characters worked with East Asian fonts. 2. Now the screen can be resized. correctly. The program no longer crashes when it is resized. 3. Added a scrollback buffer. Use the up and down arrow keys or the page up/page down keys to scroll through history. After the screen begins scrolling, press 'up arrow' to view history. 4. Many visual quirks have been fixed. This version is now dependent on iconv and wide character versions of ncurses, which I think should be everywhere these days.

* call: Fix race condition between select(2) and signal delivery.Ralf Baechle2015-06-101-6/+13
| | | | | | | | | | | | | | If a signal is delivered between the start of the main select loop and select might wait for a long time. Fixing this with select is not possible so switch to pselect. Unlike select pselect akes a struct timespec pointer as its argument so rewrite the related infrastructure to work with struct timespec instead of struct timeval. For now the race did only affect the SIGQUIT delivery. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

* call: Harden against compiler overoptimization.Ralf Baechle2015-06-102-2/+2
| | | | | | | A compiler won't know that the interrupted variable can be changed behind its back in a signal handler so it might do clever overoptimizations. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
* Call: Handle select(2) returning EINTR.Ralf Baechle2015-06-101-5/+8
| | | | | | | | | | | | | | This may happen when call is running in curses mode, and the terminal window is resized which results in a SIGWINCH sent. Ncurses as normally configured on Linux distributions will have installed a handler. If as it is the most likely case, the select call will be interrupted by the signal, select will return EINTR and call will exit. Note that this doesn't mean it's now a good idea to resize the window. Call will still not handle the screen size change properly and the output will look ugly and missformatted.

* bugfix: buffer overflow in call.c.Thomas Osterried2012-10-281-2/+2
| | | | | | | | | | | | If the call sign you connect to has 9 characters (i.E. DL9SAU-10), then call segfaults. idString in the ncruses mode routine start_screen() was dimensioned too short, and the auther had the fatal assumtion that a call is 8 characters long (and not 9), and he did limit the length in sprintf with ... %n.ns This is an old bug. Obviously, ubuntu 12.04 and 12.10 introduced better runtime checks into potential buffer overflows.
* Apply program name transformations also to man page content.Ralf Baechle2011-12-112-13/+30
| | | | | | For now these options are just honored for the call.1 and listen.1 man pages because these days these two programs generally get renamed to avoid naming conflicts with other programs.
* - Important bugfix (call did not work properly after my last patch)Thomas Osterried2009-11-112-140/+215
| | | | | | | | | - Better error handling on read() == -1 and write() == -1. Previously, the return value was not honored correctly - and could cause unexpected results. - New option "-R": Disable all remote commands like autobin (#BIN#), 7plus downloads, //echo, etc. This is useful for scripting where you just don't like the remote site to trigger uncaught conditions here.
