than by itself. Besides being duplicated code the open-coded version
also did not take care of cleaning up after the object's DAG(!).
Fixes PR bin/8905.
of the port range used by passive connections. based on work in [bin/9158]
from Takahiro Kambe <taca@sky.yamashina.kyoto.jp>
* change the way global variables are defined and extern-ed to be more
consistent.
template class [refclass]
following directives for refclass will apply to class as well.
this makes setting up a `template' class with many default settings
easy, whilst allowing for class-specific overrides
* prevent crash when the optional limitfile wasn't given to limit
* document count_users()
* document default setting of limit in ftpd.conf(5)
* crank version
* add connection limits (`limit' keyword in ftpd.conf)
* move initialisation of curclass from parse_conf() to new function
init_curclass()
* implement count_users(), which determines the number of users in a given
class. a file - /var/run/ftpd.pids-<class> - is used to store a list
of pids in use (effectively an array of pid_t's), and its size is reduced
as necessary.
* new % modifiers in format_file:
%c class
%M maximum connection count
%N current connection count
* always end_login()s, even for refused connections
bugs fixed:
* remove \n from %T output
* fix some inconsistencies in the man pages
* ensure that both `ftp' *and* `anonymous' are allowed in ftpusers.
(this was accidently broken in a recent commit to be ``or'' not ``and'')
* use MAXPATHLEN not MAXPATHLEN+1
* crank copyright date on modified files
* crank version
the name advertised to the client, even if ftpd can determine it from
the ip address that ftpd is bound to. requested by mrg.
* remove -4/-6; they were effectively no-ops since itojun's change in 1.75.
* crank version
* use .Dv and .Tn in the man pages as appropriate
* KNF a bit
The following were inspired by similar changes in openbsd, but may
have additional improvements by me:
* add more check_login tests to the parser rules
* nuke a few memory leaks in the parser rules
* clear passwords before free()ing them, for safety
* don't display \r\n in setproctitle() output
* add support for -U, which enables managing /var/run/utmp entries for
connections. solves [bin/2217] by Jason Downs <downsj@teeny.org>
* fix oob handling for STAT command
* use SIG_ERR instead of -1
as (useful for virtual ftp servers in conjunction with inetd.conf(5)'s
ability to bind to a specific address).
if this option is used, add `hostname' to the syslog messages.
* improve documentation of command-line options
* don't allow class names of `all' or `none' in ftpusers
