* libreplace: undef AI_ADDRCONFIG on QNX 6.3.0 (fix bug #6630)Matt Kraai2009-08-121-0/+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.

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>

* make the UID_WRAPPER skip checks at runtimeAndrew Tridgell2009-08-054-5/+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
* added a uid_wrapper libraryAndrew Tridgell2009-08-056-0/+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

* tdb: Reimplementation of Metze's "lib/tdb: if we know pwrite and pread are ↵Rusty Russell2009-07-311-5/+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?).

* Make tdb transaction lock recursive (samba version)Rusty Russell2009-07-203-21/+20
| | | | | | | | | | | | | | | | | | | This patch replaces 6ed27edbcd3ba1893636a8072c8d7a621437daf7 and 1a416ff13ca7786f2e8d24c66addf00883e9cb12, which fixed the bug where traversals inside transactions would release the transaction lock early. This solution is more general, and solves the more minor symptom that nested traversals would also release the transaction lock early. (It was also suggestd in Volker's comment in 6ed27ed). This patch also applies to ctdb, if the traverse.c part is removed (ctdb's tdb code never received the previous two fixes). Tested using the testsuite from ccan (adapted to the samba code).

* changes to remove the ambiguity in talloc_free() and talloc_steal() Andrew Tridgell2009-07-012-26/+109
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | These changes follow from the discussions on samba-technical. The changes are in several parts, and stem from the inherent ambiguity that was in talloc_free() and talloc_steal() when the pointer that is being changes has more than one parent, via references. The changes are: 1) when you call talloc_free() on a pointer with more than one parent the free will fail, and talloc will log an error to stderr like this: ERROR: talloc_free with references at some/foo.c:123 reference at other/bar.c:201 reference at other/foobar.c:641 2) Similarly, when you call talloc_steal() on a pointer with more than one parent, the steal will fail and talloc will log an error to stderr like this: ERROR: talloc_steal with references at some/foo.c:123 reference at other/bar.c:201 3) A new function talloc_reparent() has been added to change a parent in a controlled fashion. You need to supply both the old parent and the new parent. It handles the case whether either the old parent was a normal parent or a reference The use of stderr in the logging is ugly (and potentially dangerous), and will be removed in a future patch. We'll need to add a debug registration function to talloc.
* fixed use of reference in pytallocAndrew Tridgell2009-07-012-3/+24
| | | | | | | | | | | | The previous code caused memory leaks, and also caused situations where talloc_free could be called on pointers with multiple parents The new approach is to have two functions: py_talloc_import : steals the pointer, so it becomes wholly owned by the python object py_talloc_reference: uses a reference, so it is owned by both python and C

* tsocket/bsd: more correctly check if the cached tevent_fd is still validStefan Metzmacher2009-06-291-4/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | I some cases the pointer value of tevent_context is the same again, if we do something like: ev1 = tevent_context_init(); ... fde = tevent_add_fd(ev1, fd, TEVENT_FD_READ...); ... talloc_free(ev1); ... ev2 = tevent_context_init(); if (ev1 == ev2) { /* this can happen! */ } if (tevent_fd_get_flags(fde) == 0) { /* this is always true */ } But the "talloc_free(ev1)" will set fde->event_ctx to NULL and tevent_fd_get_flags() will always return 0. metze
* Fix ndrdump to use a common setup_logging() APIAndrew Bartlett2009-06-292-1/+18
| | | | | | | | | By adding a new common setup_logging_stdout() API, we no longer need to abuse the ABI compatability between the different setup_logging() calls in Samba3 and Samba4's DEBUG() subsystems. The revert of 49a6d757b4d944cd22c91b2838beb83f04fbe1e9 works with this to fix bug 6211. Andrew Bartlett
