(mknod_worker): New function.
(mknod32): New function.
(chroot): Free normalized path -- assuming it was actually cmalloced.
* tty.cc (create_tty_master): Tweak for new device class.
(tty::common_init): Ditto.
* winsup.h (stat_worker): Remove.
(symlink_worker): Declare.
* exceptions.cc (set_process_mask): Just call sig_dispatch_pending and don't
worry about pending_signals since sig_dispatch_pending should always do the
right thing now.
(sig_handle): Reorganize SIGCONT handling to more closely conform to SUSv3.
* pinfo.h: Move __SIG enum to sigproc.h.
(PICOM_FIFO): New enum element.
(_pinfo): Remove 'thread2signal' stuff throughout class.
(_pinfo::commune_send): Make varargs.
(_pinfo::sigtodo): Eliminate.
(_pinfo::thread2signal): Ditto.
* signal.cc (kill_worker): Eliminate call to setthread2signal.
* sigproc.cc (local_sigtodo): Eliminate.
(getlocal_sigtodo): Ditto.
(sigelem): New class.
(pending_signals): New class.
(sigqueue): New variable, start of sigqueue linked list.
(sigcatch_nonmain): Eliminate.
(sigcatch_main): Eliminate.
(sigcatch_nosync): Eliminate.
(sigcomplete_nonmain): Eliminate.
(pending_signals): Eliminate.
(sig_clear): Call signal thread to clear pending signals, unless already in
signal thread.
(sigpending): Call signal thread to get pending signals.
(sig_dispatch_pending): Eliminate use of pending_signals and just check
sigqueue.
(sigproc_terminate): Eliminate all of the obsolete semaphore stuff. Close
signal pipe handle.
(sig_send): Eliminate all of the obsolete semaphore stuff and use pipe to send
signals.
(getevent): Eliminate.
(pending_signals::add): New function.
(pending_signals::del): New function.
(pending_signals::next): New function.
(wait_sig): Eliminate all of the obsolete semaphore stuff. Use pipe to
communicate and maintain a linked list of signals.
* sigproc.h: Move __SIG defines here. Add __SIGPENDING.
(sig_dispatch_pending): Remove "C" specifier.
(sig_handle): Accept a mask argument.
* thread.cc: Remove signal handling considerations throughout.

/* TODO, CV 2008-11-25: The check against saved_sid is a kludge and a
|
|
|
|
shortcut. We must check if it's really feasible in the long run.
|
|
|
|
The reason to add this shortcut is this: sshd switches back to the
|
|
|
|
privileged user running sshd at least twice in the process of
|
|
|
|
authentication. It calls seteuid first, then setegid. Due to this
|
|
|
|
order, the setgroups group list is still active when calling seteuid
|
|
|
|
and verify_token treats the original token of the privileged user as
|
|
|
|
insufficient. This in turn results in creating a new user token for
|
|
|
|
the privileged user instead of using the orignal token. This can have
|
|
|
|
unfortunate side effects. The created token has different group
|
|
|
|
memberships, different user rights, and misses possible network
|
2008-11-27 01:21:04 +08:00
|
|
|
credentials.
|
2008-11-26 18:18:10 +08:00
|
|
|
Therefore we try this shortcut now. When switching back to the
|
|
|
|
privileged user, we probably always want a correct (aka original)
|
|
|
|
user token for this privileged user, not only in sshd. */
