Log:
MFC r257398 (by sbruno):
Quiesce warnings by updating headerfile includes
r257404 | sbruno | 2013-10-30 23:41:18 +0100 (Wed, 30 Oct 2013) | 9 lines
Quiesce two warnings:
1. define the CODE * as const
2. restructure function to eliminate warning about exiting with no return.
severity_map() never returns when it can't find an appropriate sysylog
facility, and it longjmp()'s away into error code handling. Keep this
behavior by stashing the facility value found during our search and
checking for -1 if found.
MFC r257405 (by sbruno):
Quiesce warning, which could be a bug IMO, by correctly defining the host_info
structure name
MFC r257406 (by sbruno):
Queisce warning about undeclared function usage.
yp_get_default_domain is defined in workaround.c but is not declared
in any header file. Tie the declaration to the same #define conditional
used when the function is called, NETGROUP
MFC r272949 (by pfg):
tcpd: complete function prototypes.
This clears up at least a build issues on mysql-server
ports. While here also replace some spaces with tabs
in our headers.
PR: 42336
MFC r272950 (by pfg):
tcpd.h: add prototype for hosts_ctl
According the hosts_access(3) man page the hosts_ctl() prototype
should be in tcpd.h. For now, follow other declarations and don't
add the arguments in the prototype.
Reference:
https://www.illumos.org/issues/4385
PR: 32808
MFC r311459:
Put proper prototypes in tcpd.h
Clang 4.0.0 complains about tcpd.h's not-really-prototypes, e.g.:
/usr/include/tcpd.h:75:24: error: this function declaration is not a prototype [-Werror,-Wstrict-prototypes]
extern int hosts_access(); /* access control */
^
To fix this, turn these declarations into real prototypes. While here,
garbage collect the incompatible rfc931() function from scaffold.c, as
it is never used.
Reviewed by: emaste
Differential Revision: https://reviews.freebsd.org/D9052
MFC r311461:
Also remove unnecessary extern keywords from tcpd.h.
Noticed by: kib
MFC r311556:
After r311459, some ports can break, because a few of the newly added
prototypes in <tcpd.h> use FILE. Pull in a minimal forward declaration
of FILE from <stdio.h> to minimize impact. Sorry for the breakage.
