2007-10-10r2709: finally solved the talloc reference problem.Andrew Tridgell1-39/+94
The problem was that the simple "uint_t ref_count;" in a talloc chunk did not give enough information. It told us that a pointer was referenced more than once, but it didn't say who it was referenced by. This means that when the pointer was freed we had no sane way to clean up the reference. I have now replaced ref_count with a "refs" list, which means that references point to the pointer, and the pointer has a linked list of references. So now we can cleanup from either direction without losing track of anything. I've also added a LOCAL-TALLOC smbtorture test that tests talloc behaviour for some common uses. (This used to be commit 911a8d590cb184bcb892810729955c2c4cf02550)

2007-10-10r2677: - fixed a bug in the recursive logic talloc_free() when there areAndrew Tridgell1-21/+50
circular references (circular references are allowed, they just need to be handled carefully inside talloc) - mark talloc_reference() pointers nicely in the --leak-report-full code, so you see what has a reference to what in a useful manner (This used to be commit a87d3d11344069284604a7294a54cadcc6e1a096)
2007-10-10r2675: added a convenience functionAndrew Tridgell1-0/+35
void *talloc_reference(const void *context, const void *ptr); this function makes a secondary reference to ptr, and hangs it off the given context. This greatly simplifies some of the current reference counting code in the samr server and I suspect it will be widely used in other places too. the way you use it is like this: domain_state->connect_state = talloc_reference(domain_state, connect_state); that makes the element connect_state of domain_state a secondary reference to connect_state. The connect_state structure will then only be freed when both domain_state and the original connect_state go away, allowing you to free them independently and in any order. you could do this alrady using a talloc destructor, and that is what the samr server did previously, but that meant this construct was being reinvented in several places. So this convenience function sets up the destructor for you, giving a much more convenient and less error prone API. (This used to be commit dc5315086156644fad093cbe6b02d999adba8540)
2007-10-10r2674: I have realised that talloc() should have its context marked const, asAndrew Tridgell3-46/+96
a const pointer really means that "the data pointed to by this pointer won't change", and that is certainly true of talloc(). The fact that some behind-the-scenes meta-data can change doesn't matter from the point of view of const. this fixes a number of const warnings caused by const data structures being passed as talloc contexts. That will no longer generate a warning. also changed the talloc leak reporting option from --leak-check to --leak-report, as all it does is generate a report on exit. A new --leak-report-full option has been added that shows the complete tree of memory allocations, which is is quite useful in tracking things down. NOTE: I find it quite useful to insert talloc_report_full(ptr, stderr) calls at strategic points in the code while debugging memory allocation problems, particularly before freeing a major context (such as the connection context). This allows you to see if that context has been accumulating too much data, such as per-request data, which should have been freed when the request finished. (This used to be commit c60ff99c3129c26a9204bac1c6e5fb386114a923)

2007-10-10r2671: we're getting too many errors caused by the talloc_realloc() API notAndrew Tridgell6-20/+18
taking a context (so when you pass a NULL pointer you end up with memory in a top level context). Fixed it by changing the API to take a context. The context is only used if the pointer you are reallocing is NULL. (This used to be commit 8dc23821c9f54b2f13049b5e608a0cafb81aa540)
2007-10-10r2667: Remove forward declaration of static function from function. GCC 3.5 ↵Jelmer Vernooij1-2/+3

2007-10-10r2649: - used some cpp tricks to make users of talloc() and talloc_realloc()Andrew Tridgell2-7/+20
to get auto-naming of pointers very cheaply. - fixed a couple of memory leaks found with the new tricks A typical exit report for smbd is now: talloc report on 'null_context' (total 811 bytes in 54 blocks) auth/auth_sam.c:334 contains 20 bytes in 1 blocks struct auth_serversupplied_info contains 498 bytes in 33 blocks UNNAMED contains 8 bytes in 1 blocks lib/data_blob.c:40 contains 16 bytes in 1 blocks iconv(CP850,UTF8) contains 61 bytes in 4 blocks iconv(UTF8,CP850) contains 61 bytes in 4 blocks iconv(UTF8,UTF-16LE) contains 67 bytes in 4 blocks iconv(UTF-16LE,UTF8) contains 67 bytes in 4 blocks UNNAMED contains 13 bytes in 1 blocks which is much better than before (This used to be commit 6e721393d03afd3c2f8ced8422533547a9e33342)

(This used to be commit 28dcd2202948b003f8d13951395baa4a722593f4)
2007-10-10r2641: talloc_p() now produces a named talloc pointer, with the nameAndrew Tridgell1-3/+31
auto-derived from the type you are allocating. This is done with basically zero overhead by relying on the stringify operator in cpp producing string constants. the result is that --leak-check nicely names all pointers that come from talloc_p() (This used to be commit bd86ebe2972af4d424df20db1e422919aa6203d0)
2007-10-10r2640: valgrind does a great job on some types of memory leaks, but is slowAndrew Tridgell2-5/+80
and can't properly handle leaks of doubly linked lists which we use a lot (as the memory is always reachable). Even with --show-reachable its hard to track leaks down sometimes. I realised that talloc does have the necessary information to track these, and by using the cascading property of the new talloc it can report on leaks in a much more succinct fashion than valgrind can. I have added a new samba option --leak-check that applies to all Samba tools. When enabled it prints a leak report summarising all top level contexts that are present when the program exits. A typical report looks like this: talloc report on 'null_context' (total 1071 bytes in 52 blocks) iconv(CP850,UTF8) contains 43 bytes in 3 blocks UNNAMED contains 24 bytes in 1 blocks UNNAMED contains 24 bytes in 1 blocks dcesrv_init contains 604 bytes in 26 blocks server_service contains 120 bytes in 6 blocks UNNAMED contains 24 bytes in 1 blocks UNNAMED contains 24 bytes in 1 blocks server_service contains 104 bytes in 4 blocks server_context contains 12 bytes in 2 blocks iconv(UTF8,UTF-16LE) contains 46 bytes in 3 blocks iconv(UTF-16LE,UTF8) contains 46 bytes in 3 blocks the numbers are recursive summaries for all the memory hanging off each context. this option is not thread safe when used, but the code is thread safe if the option is not given, so I don't think thats a problem. (This used to be commit 96d33d36a5639e7fc46b14a470ccac674d87c62a)
2007-10-10r2639: we doon't need the valid_table code, so get rid of itAndrew Tridgell1-56/+0

2007-10-10r2638: do lazy initialisation of iconv handles, so we don't initialise aAndrew Tridgell1-39/+29
handle unless we use it. This saves quite a bit of memory (libc chews a lot loading a handle). Typically smbd now loads 3 handles, instead of 36. (This used to be commit 60e8d154fda548862cd6f8e8c1dadd64b3c4bd9c)
2007-10-10r2634: use discard_const_p() in a few placesAndrew Tridgell3-6/+9

2007-10-10r2632: a new approach to handling const errors. We have had huge numbers ofAndrew Tridgell2-2/+22
const warnings for a long time, and no real way to approach a solution. Some of them are unavoidable due to the way the C standard works (for example, any function that provides strchr() like functionality _must_ produce a const warning) I will be converting a bunch of places that currently produce const warnings to use the discard_const_p(). Some of these will be unavoidable const problems, some of them will be ones we will fix up over time. At least this change means we will no longer be swamped with const warnings, and we will easily be able to see when new problems emerge.

need to add MSG_WAITALL to the recv() flags. This is needed by the current server code or sometimes it will fail with a receive error. (This used to be commit 4cb11fb77acf74ab53bf5782a114151965c558f0)
2007-10-10r2621: - now that the client code is non-blocking, we no longer needAndrew Tridgell1-73/+0
write_data and read_data, which are inherently blocking operations - got rid of some old NBT keepalive routines that are not needed (This used to be commit e73b4ae4e500d3b7ee57e160e0f8b63c99b2542a)

2007-10-10r2581: added "hosts allow" and "hosts deny" checking in smbd. I needed thisAndrew Tridgell5-0/+386
as my box keeps getting hit by viruses spreading on my companies internal network, which screws up my debug log badly (sigh). metze, I'm not sure if you think access.c should go in the socket library or not. It is closely tied to the socket functions, but you may prefer it separate. The access.c code is a port from Samba3, but with some cleanups to make it (slighly) less ugly. (This used to be commit 058b2fd99e3957d7d2a9544fd27071f1122eab68)
2007-10-10r2577: - I recently found out that charaters below 0x3F are guaranteed not toAndrew Tridgell1-45/+12
occur as secondary bytes in any multi-byte character set. This allows for a very simple optimisation in strchr_m() and strrchr_m(). It might be a good idea to pick this up for Samba3. - the horrible toktocliplist() is only used in clitar.c, so move it there, to prevent anyone else from being tempted to use it. (This used to be commit 663b7b75ddd838ce547425b07d7ce4d4606fb479)

2007-10-10r2552: Character set conversion and string handling updates.Andrew Bartlett3-444/+267
The intial motivation for this commit was to merge in some of the bugfixes present in Samba3's chrcnv and string handling code into Samba4. However, along the way I found a lot of unused functions, and decided to do a bit more... The strlen_m code now does not use a fixed buffer, but more work is needed to finish off other functions in str_util.c. These fixed length buffers hav caused very nasty, hard to chase down bugs at some sites. The strupper_m() function has a strupper_talloc() to replace it (we need to go around and fix more uses, but it's a start). Use of these new functions will avoid bugs where the upper or lowercase version of a string is a different length. I have removed the push_*_allocate functions, which are replaced by calls to push_*_talloc. Likewise, pstring and other 'fixed length' wrappers are removed, where possible. I have removed the first ('base pointer') argument, used by push_ucs2, as the Samba4 way of doing things ensures that this is always on an even boundary anyway. (It was used in only one place, in any case). (This used to be commit dfecb0150627b500cb026b8a4932fe87902ca392)
2007-10-10r2542: I really don't like the 'substitute' code, and I particularly don'tAndrew Bartlett1-25/+0
like it in the mainline code (outside the smb.conf magic). We will need to have a more useful 'helper' routine for this, but for now we at least get a reliable IP address. Also remove the unused 'socket' structure in the smb server - it seems to have been replaced by the socket library. Andrew Bartlett (This used to be commit d8fd19a2020da6cce691c0db2b00f42e31d672cc)
