2014-11-02os-posix: use global daemon_pipe instead of cryptic fds[1]Michael Tokarev1-4/+6
When asked to -daemonize, we fork a child and setup a pipe between it and parent to pass exit status. os-posix.c used global fds[2] array for that, but actually only the writing side of the pipe is needed to be global, and this name is really too generic. Use just one interger for the writing side of the pipe, and name it daemon_pipe to be more understandable than cryptic fds[1].

2014-11-02dump: Fix dump-guest-memory termination and use-after-closeGonglei1-7/+4
dump_iterate() dumps blocks in a loop. Eventually, get_next_block() returns "no more". We then call dump_completed(). But we neglect to break the loop! Broken in commit 4c7e251a. Because of that, we dump the last block again. This attempts to write to s->fd, which fails if we're lucky. The error makes dump_iterate() return failure. It's the only way it can ever return. Theoretical: if we're not so lucky, something else has opened something for writing and got the same fd. dump_iterate() then keeps looping, messing up the something else's output, until a write fails, or the process mercifully terminates. The obvious fix is to restore the return lost in commit 4c7e251a. But the root cause of the bug is needlessly opaque loop control. Replace it by a clean do ... while loop. This makes the badly chosen return values of get_next_block() more visible. Cleaning that up is outside the scope of this bug fix.

It looks like smbd always logs to /var/log/samba/log.$progname even if config file specifies different logfile -- when it needs to log something before completing reading the config file. But if it can't open it for writing, it fails and exits. Tell smbd to use our temp dir as logbase (-l option) to avoid that. The same option is used by samba3 and samba4, so there should be no incompatible changes.

2014-11-02Revert "os-posix: report error message when lock file failed"Michael Tokarev1-2/+0
This reverts commit e5048d15ce6addae869f23514b2a1f0d4466418a. qemu_create_pidfile() is only created from main(), and there, if that function returns failure, os_pidfile_error() function is called, to, guess that, report error (which is done differently whenever we're daemonizing or not). qemu_create_pidfile() function has several error returns, this lockf() failure is one of them, there are others (another shown in the patch context too). So this patch makes whole thing inconsistent at least. If we need to show error message when we're daemonizing, it looks like we should modify os_pidfile_error() routine to always report error and only after that check for daemon mode. This way all errors will be reported the same way. Signed-off-by: Michael Tokarev <mjt@tls.msk.ru>

2014-10-28libcacard: Lock NSS cert db when selecting an applet on an emulated cardRay Strode1-0/+5
When a process in a guest uses an emulated smartcard, libcacard running on the host passes the PIN from the guest to the PK11_Authenticate NSS function. The first time PK11_Authenticate is called the passed in PIN is used to unlock the certificate database. Subsequent calls to PK11_Authenticate will transparently succeed, regardless of the passed in PIN. This is a convenience for applications provided by NSS. Of course, the guest may have many applications using the one emulated smart card all driven from the same host QEMU process. That means if a user enters the right PIN in one program in the guest, and then enters the wrong PIN in another program in the guest, the wrong PIN will still successfully unlock the virtual smartcard. This commit forces the NSS certificate database to be locked anytime an applet is selected on an emulated smartcard by calling vcard_emul_logout.
