2009-08-29tevent: Fix a segfault upon the first signalVolker Lendecke1-0/+6
When the first signal arrives, tevent_common_signal_handler() crashed: "ev" is initialized to NULL, so the first "write(ev->pipe_fds[1], &c, 1);" dereferences NULL. Rusty, Tridge, please check. Also, can you tell me a bit more about the environment you tested this in? I'd be curious to see where this survived. Thanks, Volker
2009-08-28lib/tevent: close pipe_fds on event_context destructionRusty Russell1-0/+2
The "hack_fds" were never closed before; now they're inside event_context they should be closed when that is destroyed. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2009-08-28lib/tevent: handle tevent_common_add_signal on different event contexts.Rusty Russell2-14/+31
I don't know if this is a problem in real life. The code assumes there's only one tevent_context; all signals will notify the first event context. That's counter-intuitive if you ever use more than one, and there's nothing else in this code which prevents it AFAICT. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2009-08-28lib/tevent: fix race with signals and tevent_common_add_signalRusty Russell1-20/+20
We carefully preserve the old signal handler, but we replace it before we've set up everything; in particular, if we fail setting up the pipe_hack we could write a NUL char to stdout (fd 0), instead of calling the old signal handler. Replace the signal handler as the very last thing we do. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

2009-08-28lib/tevent: remove spectacularly complicated manual subtractionRusty Russell1-4/+1
To be completely honest, I don't quite know whether to laugh or cry at this one: 1 + (0xFFFFFFFF & ~(s.seen - s.count)) == 1 + (~(s.seen - s.count)) # s.seen, s.count are uint32_t == s.count - s.seen # -A == ~A + 1 Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

2009-08-12libreplace: undef AI_ADDRCONFIG on QNX 6.3.0 (fix bug #6630)Matt Kraai1-0/+14
Some of the functions in source3/lib/util_sock.c use AI_ADDRCONFIG. On QNX 6.3.0, this macro is defined but, if it's used, getaddrinfo will fail. This prevents smbd from opening any sockets. If I undefine AI_ADDRCONFIG on such systems and allow lib/replace/system/network.h to define it to be 0, this works around the issue. Signed-off-by: Stefan Metzmacher <metze@samba.org>

2009-08-06There is one signedness issue in tdb which prevents traverses of TDB recordsRusty Russell1-9/+21
over the 2G offset on systems which support 64 bit file offsets. This fixes that case. On systems with 32 bit offsets, expansion and fcntl locking on these records will fail anyway. SAMBA already does '#define _FILE_OFFSET_BITS 64' in config.h (on my 32-bit x86 Linux system at least) to get 64 bit file offsets. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

2009-08-05make the UID_WRAPPER skip checks at runtimeAndrew Tridgell4-5/+17
This fixes two issues pointed out by Andrew. It adds a runtime uwrap_enabled() call that wraps the skips needed for uid emulation. It also makes the skip in the directory_create_or_exist() function only change the uid checking code, not the permissions code
2009-08-05added a uid_wrapper libraryAndrew Tridgell6-0/+236
This library intercepts seteuid and related calls, and simulates them in a manner similar to the nss_wrapper and socket_wrapper libraries. This allows us to enable the vfs_unixuid NTVFS module in the build farm, which means we are more likely to catch errors in the token manipulation. The simulation is not complete, but it is enough for Samba4 for now. The major areas of incompleteness are: - no emulation of setreuid, setresuid or saved uids. These would be needed for use in Samba3 - no emulation of ruid changing. That would also be needed for Samba3 - no attempt to emulate file ownership changing, so code that (for example) tests whether st.st_uid matches geteuid() needs special handling

2009-07-31tdb: Reimplementation of Metze's "lib/tdb: if we know pwrite and pread are ↵Rusty Russell1-5/+10
thread/fork safe tdb_reopen_all() should be a noop". This version just wraps the reopen code, so we still re-grab the lock and do the normal sanity checks. The reason we do this at all is to avoid global fd limits, see: http://forums.fedoraforum.org/showthread.php?t=210393 Note also that this whole reopen concept is fundamentally racy: if the parent goes away before the child calls tdb_reopen_all, the database can be left without an active lock and another TDB_CLEAR_IF_FIRST opener will clear it. A fork_with_tdbs() wrapper could use a pipe to solve this, but it's hardly elegant (what if there are other independent things which have similar needs?).
