5a1caf9a5d Add missing argument after r218192. 2011-02-02 20:00:35 +00:00
Pawel Jakub Dawidek
01ab52c021 - Rename proto_descriptor_{send,recv}() functions to
proto_connection_{send,recv} and change them to return proto_conn
  structure. We don't operate directly on descriptors, but on
  proto_conns.
- Add wrap method to wrap descriptor with proto_conn.
- Remove methods to send and receive descriptors and implement this
  functionality as additional argument to send and receive methods.

1c1933226f Add proto_connect_wait() to wait for connection to finish.
If timeout argument to proto_connect() is -1, then the caller needs to use
this new function to wait for connection.

This change is in preparation for capsicum, where sandboxed worker wants
to ask main process to connect in worker's behalf and pass descriptor
to the worker. Because we don't want the main process to wait for the
connection, it will start async connection and pass descriptor to the
worker who will be responsible for waiting for the connection to finish.

2ec483c58e - Use pjdlog for assertions and aborts as this will log assert/abort message
to syslog if we run in background.
- Asserts in proto.c that method we want to call is implemented and remove
  dummy methods from protocols implementation that are only there to abort
  the program with nice message.

90e0ec14c1 Fix the 'scan hang' issue.
When requesting a scan and one is already in progess, e.g. while in scan
state, we happily wait for a scan done notification. Though, this
notification might never be sent, e.g. if we are trying to find a network
to associate to and there is none. Instead of always waiting for a
notification just do so if a new scan has been started. For both cases the
scan cache is used to report available networks even if the content might
not be fresh.

a272741053 When doing a scan while being associated it is possible that the scan
is deferred for the time it takes to flush the TX queue. This work being
done the scan then is continued, but only if it is marked to do so. As
the 'ifconfig scan' request is meant to be used after the interface is
brought up, request a background scan by default. This behaviour is
already documented in manual page.

This fixes on possible case where 'ifconfig scan' hangs infinitely.

6d7967de8a Drop privileges in worker processes.
Accepting connections and handshaking in secondary is still done before
dropping privileges. It should be implemented by only accepting connections in
privileged main process and passing connection descriptors to the worker, but
is not implemented yet.

49499e981e Implement function that drops privileges by:
- chrooting to /var/empty (user hast home directory),
- setting groups to 'hast' (user hast primary group),
- setting real group id, effective group id and saved group id to 'hast',
- setting real user id, effective user id and saved user id to 'hast'.
At the end verify that those operations where successfull.

579fd4b2ff Add function to assert that the only descriptors we have open are the ones
we expect to be open. Also assert that they point at expected type.

Because openlog(3) API is unable to tell us descriptor number it is using, we
have to close syslog socket, remember assert message in local buffer and if we
fail on assertion, reopen syslog socket and log the message.

7649cb0043 The dump, fsck_ffs, fsdb, fsirand, newfs, makefs, and quot utilities
include sys/time.h instead of time.h. This include is incorrect as
per the manpages for the APIs and the POSIX definitions. This commit
replaces sys/time.h where necessary with time.h.

The commit also includes some minor style(9) header fixup in newfs.

This commit is part of a larger effort by Garrett Cooper started in
//depot/user/gcooper/posix-conformance-work/ -- to make FreeBSD more
POSIX compliant.

acf0ab0669 init: Only run /etc/rc.shutdown if /etc/rc was run.
It does not make sense to shut down daemons that were not started. In
particular, this fixes loss of mixer settings when shutting down using
shutdown(8), init(8) or ctrl+alt+del from single-user mode.

If /etc/rc reboots, /etc/rc.shutdown is not run.

Also fix segfaults and other erratic behaviour if init receives SIGHUP or
SIGTSTP while in single-user mode.

This commit does not attempt to fix any badness with signal handlers
(assumption that pointers can be read and written atomically, EINTR race
condition). I believe it does not make this badness any worse.

f8e4b4ef49 sysctl(8) should use the CTLTYPE to determine the type of data when
reading.  (This was already done for writing to a sysctl).  This
requires all SYSCTL setups to specify a type.  Most of them are now
checked at compile-time.

Remove SYSCTL_*X* sysctl additions as the print being in hex should be
controlled by the -x flag to sysctl(8).
