* Block SIGURG while reading from the control channel.Yaroslav Tykhiy2003-07-091-0/+6
| | | | | | | | | | | | | | | | | | Rationale: SIGURG is configured by ftpd to interrupt system calls, which is useful during data transfers. However, SIGURG could interrupt I/O on the control channel as well, which was mistaken for the end of the session. A practical example could be aborting the download of a tiny file, when the abort sequence reached ftpd after ftpd had passed the file data to the system and returned to its command loop.

* Improve error handling in getline():Yaroslav Tykhiy2003-07-091-4/+7
| | | | | | | | | | | | - always check the return value from getc(3) for EOF; - if the attempt to read the TELNET command byte has returned EOF, exit from the loop instead of using the EOF value as a normal character. MFC after: 1 week Notes: svn path=/head/; revision=117351

* Avoid using the global offset table to get the address of _DYNAMIC inJake Burkholder2003-07-042-1/+18
| | | | | | | | | | | | rtld. When _DYNAMIC is referenced normally from C the global offset table is used implicitly, but newer versions of binutils don't initialize it statically in the binary, so this doesn't work until rtld is relocated, which _DYNAMIC is needed for... So, as on other systems with the same problem, we disassemble a call instruction to _DYNAMIC in order to get its address. Notes: svn path=/head/; revision=117211

* Improve the manpage language a bit.Yaroslav Tykhiy2003-06-171-1/+1
| | | | | | | | | | | A PPP login program is started _automatically_ (i.e., without human intervention) even with the "pl" capability unset, as soon as a PPP frame is detected. But with "pl" set, a PPP login program is started independently of the result of PPP detection (which is rendered unnecessary then,) i.e. _unconditionally_. Notes: svn path=/head/; revision=116482

| | | | | | | | | | | | | | | | | | don't reveal the info in reply to the SYST command. Get rid of using the "unix" macro at the same time. It was a rather poor way to check if the system was Unix since there were quite a few Unix clones out there whose cc didn't define "unix" (e.g., NetBSD.) It was also sensitive to the C standard used, which caused unnecessary trouble: With -std=c99, it should have been "__unix__", and so on.
