Added fsync() after writing the pid to the lock file to push the result
to the file system immediately.
Any error in the procedure is now treated as fatal, and the daemon will
exit(1). (Previously only the open and the lock had to succeed.)
Any error is logged and is (now) output to stderr.
If the pid file is locked, the error message reports the pid which owns
the lock.

Implemented less onerous ways of including descriptions of errors
and IP addresses in logging and other messages.
Implemented mapping of error numbers to error names, which is
generally more meaningful.

* pid_output.c: (pid_output_lock) Eliminate static function, and just
use the #ifdef to decide which version of the function to include.
This eliminates a compilation problem with gcc4. And fix the
non-fcntl version so that it actually compiles. Exit with
status 1 instead of -1 on error.

* bgp_main.c: (sigint) Use zlog_notice for termination message.
(main) Use zlog_notice for startup announcement.
* isis_main.c: (sigint,sigterm) Use zlog_notice for termination message.
(terminate) This function should be static, not global.
(main) Use zlog_notice for startup announcement, and remove
ifdef ZEBRA_VERSION.
* version.h.in: Remove declaration for pid_output_lock, this function
is now static, not global.
* pid_output.c: (pid_output_lock) This function should be static, not
global. And remove "old umask" error message, since it was really
an unimportant debug message, not an error.
(pid_output) Need to declare static function pid_output_lock.
* ospf6_main.c: (sigint,sigterm) Use zlog_notice for termination
message.
(main) Remove commented-out call to pid_output_lock (which should
never be called other than from inside pid_output). And use
zlog_notice to print the startup message, which now includes
the vty port.
* ospf_main.c: (sigint) Use zlog_notice for termination message.
(main) Issue a startup announcement using zlog_notice.
* rip_main.c: (sigint) Use zlog_notice for termination message.
(main) Add a startup announcement using zlog_notice.
* ripng_main.c: (sighup) Remove spurious terminating message.
(sigint) Use zlog_notice for termination message.
(main) Issue a startup announcement using zlog_notice.
* main.c: (sigint) Use zlog_notice for termination message.
(main) Add a startup announcement using zlog_notice.

* pid_output.c: (pid_output_lock) Fix 2 bugs: when locking, should
set l_whence to SEEK_SET, not SEEK_END. And after writing new
pid to file, must ftruncate to eliminate any extraneous bytes left
over from the last time a pid was written.

* global: Replace strerror with safe_strerror. And vtysh/vtysh.c
needs to include "log.h" to pick up the declaration.

* configure.ac (and everywhere a regular file is opened for
writing): use file permissions from configure rather than
compiled-in umask.
|
| |
|
|
| |
* lib/pid_output.c: (pid_output_lock) undo paulj's mindless edit.
|
| |
|
|
|
|
|
| |
* lib/pid_output.c: (pid_output) call pid_output_lock if we have
fcntl().
(pid_output_lock) grab exclusive write lock on pid file, rather
than rely on (fragile) exclusive create.
