Modified Files:

Log Message:
More file existence/length checks, with only a WARNING log level (not error) since some QWKnet nodes apparently like to start concurrent QWK packet downloads and inevitably one finishes first, deleting the file, and the second transfer logs and error. Examples:
8/14 08:10:06p 2296 <EPHRAM> downloading QWK packet (1320 bytes) in passive mode
8/14 08:10:06p 3792 <EPHRAM> downloading QWK packet (1320 bytes) in passive mode
8/14 08:10:06p 2296 <EPHRAM> DATA Transfer successful: 1320 bytes sent in 0 seconds (2640 cps)
8/14 08:10:06p 3792 <EPHRAM> !DATA ERROR 2 (No such file or directory) line 1376 opening s:\sbbs\data\file/0888.qwk
8/14 11:28:55p 2576 <POTOGOLD> downloading QWK packet (27129 bytes) in passive mode
8/14 11:28:55p 2576 <POTOGOLD> DATA Transfer successful: 27129 bytes sent in 0 seconds (54258 cps)
8/14 11:28:55p 1924 <POTOGOLD> downloading QWK packet (4294967295 bytes) in passive mode
8/14 11:28:56p 1924 <POTOGOLD> !DATA ERROR 2 (No such file or directory) line 1376 opening s:\sbbs\data\file/0168.qwk

Also some more 64-bit file length support (flength returns an off_t now, not a ulong).
And ftell() returns a long (not a ulong).

Modified Files:
src/sbbs3/ftpsrvr.c
Log Message:
Create the pack*.now with fmutex() to prevent simultaneous QWK packs

Probably only a problem on Vertrauen, but some QWKnet nodes, for some unknown reason, like to FTP-connect multiple times concurrently and request to download a QWK packet. This creates a race condition where the QWK packet gets created/downloaded/deleted before the second FTP connection can successfully download the same file, thus logging an error "opening file " on the server (VERT). So if the pack*.now file already exists, reject the download request. "What are doing?" is what I really want to ask these nodes, but better just throw them an error response and quietly move on.

Log Message:
Don't delete pack####.now upon FTP-logoff

When a user logins to the FTP server concurrently, this creates a
race condition with an/the other FTP session that may be creating/
downloading a QWK packet. On Vertrauen, this results in the
occasional error removing the file since it was removed unexpectedly:
!ERROR 2 (No such file or directory) in main.cpp line 2747 (event_thread) removing "/sbbs/data/pack1111.now" access=0

Log Message:
Detect TLS startup errors correct/fully

We can't (apparently) only rely on the return value of start_tls(), we have to check the value of the crypt session too.
This fix the possibility of this happening:
Jun 7 18:07:26 sbbs synchronet: ftp 0058 TLS ERROR 'No permiss.to perform this operation' (-21) opening keyset
Jun 7 18:07:26 sbbs synchronet: ftp 0058 <192.168.1.25> initialized TLS successfully

Instead, we'll detect the failure and disable FTPS support, logging "failed to initialize TLS successfully".

Log Message:
Fix segfault reported with ftpalias.cfg support in some cases

ftpalias() can return true even when the directory is not set to a valid directory index (i.e. set to -1), so using as an array index would definitely segfault. Part of commit 8ad30b6c by Deuce 3 years ago.

I didn't test this as I'm not sure exactly the combination of ftpalias.cfg content and FTP command received that would trigger this, but it's most definitely a bug.

So should fix the segfault reported in issue #288.

Log Message:
Fix FTPS upload failure: !DATA ERROR 0 receiving on data socket

Don't treat CRYPT_ERROR_COMPLETE (-24) as a socket error during upload since it's an indication that the remote closed the connection and is the normal "end of file/transfer" indicator, not an error. 'rd' is already 0 in this case, so no need to set at all (since recv() returns 0 upon disconnect and that's what we're emulating here).

Fixes issue #309 reported by Jas Hud.

Actually, this assessment was wrong. fmutex_open() was memsetting the fmutex_t to zero.
