2007-10-10r2675: added a convenience functionAndrew Tridgell2-47/+46
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 Tridgell6-50/+106
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)
2007-10-10r2673: in the rpc server, free up the old call when we decide to extend anAndrew Tridgell1-1/+3
existing call rather than creating a new one. This prevents call structures hanging around on the rpc connection context until it is closed (This used to be commit c51ca7c0e73b97435c245cd440a4fb979cf6a4f3)

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)
2007-10-10r2670: use a destructor to auto-close the samr ldb when the last userAndrew Tridgell1-15/+18

2007-10-10r2661: fixed a client side memory leak in the clilist code.Andrew Tridgell1-3/+3
This sort of bug happens quite easily with the new talloc_realloc() interface. talloc_realloc() now looks like this: void *talloc_realloc(void *ptr, size_t size); and if ptr is not NULL then everything is fine. If ptr is NULL then talloc_realloc() presumes you want to allocate in the NULL context, which is probably not what is wanted. For now the solution is to initialise ptr like this: ptr = talloc(mem_ctx, 0); so when the realloc happens it has a context to get hold of. I might change the interface of talloc_realloc() later to prevent this problem in a more robust manner (This used to be commit bd813dfb1b08b586dc71f9cec4eb65b35ea808fe)
2007-10-10r2660: - converted the libcli/raw/ library to use talloc_increase_ref_count()Andrew Tridgell24-139/+285
rather than manual reference counts - properly support SMBexit in the cifs and posix backends - added a logoff method to all backends With these changes the RAW-CONTEXT test now passes against the posix backend (This used to be commit c315d6ac1cc40546fde1474702a6d66d07ee13c8)

2007-10-10r2654: fixed some more server memory leaks. We are now down to a single leakAndrew Tridgell9-10/+26
of 16 bytes, caused by the 16 byte data_blob in the smb_signing code. (This used to be commit 2f1b788e09686e065d22f621f5c0c585192c6740)

2007-10-10r2649: - used some cpp tricks to make users of talloc() and talloc_realloc()Andrew Tridgell5-11/+37
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)
2007-10-10r2648: - use a destructor on struct server_connection to simplify theAndrew Tridgell11-66/+51
connection termination cleanup, and to ensure that the event contexts are properly removed for every process model - gave auth_context the new talloc treatment, which removes another source of memory leaks. (This used to be commit 230e1cd777b0fba82dffcbd656cfa23c155d0560)

2007-10-10r2643: convert more of the auth subsyystem to the new talloc methods. ThisAndrew Tridgell7-52/+35
also fixes a memory leak found with --leak-check. (This used to be commit f19201ea274f0a542314c61c4af676197bf154ad)
2007-10-10r2642: smb_iconv_t is a pointer, so checks against -1 errors should use a castAndrew Tridgell1-1/+1
(This used to be commit 28dcd2202948b003f8d13951395baa4a722593f4)
2007-10-10r2641: talloc_p() now produces a named talloc pointer, with the nameAndrew Tridgell2-4/+32
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
(This used to be commit 480636ebbca102172621609496bdab682d4bda8a)
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)
2007-10-10r2635: mem_ctx cleanups on the lsa and netlogon pipes in the rpc serverAndrew Tridgell3-50/+19
(This used to be commit 1ee5ed4197f49f12372835f66160801f19ee35a6)
2007-10-10r2634: use discard_const_p() in a few placesAndrew Tridgell5-10/+13
(This used to be commit 56ecda2178e33508c55c6195ccec41c06e099d6f)
2007-10-10r2633: fixed some function types in the (unused) print backendAndrew Tridgell1-2/+2
(This used to be commit e9803058ecc0b0f849aee48a077bff4e2c8feaa5)
2007-10-10r2632: a new approach to handling const errors. We have had huge numbers ofAndrew Tridgell3-2/+24
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. (This used to be commit fec3288ad6ce58e8273e3f16e88037db49ecf046)
2007-10-10r2631: the strchr family of functions should not return const strings.Andrew Tridgell1-3/+3

2007-10-10r2629: convert gensec to the new talloc modelAndrew Tridgell13-45/+40
by making our gensec structures a talloc child of the open connection we can be sure that it will be destroyed when the connection is dropped. (This used to be commit f12ee2f241aab1549bc1d9ca4c35a35a1ca0d09d)

2007-10-10r2627: use the new talloc capabilities in a bunch more places in the rpcAndrew Tridgell11-94/+64
server code. This fixes a number of memory leaks I found when testing with valgrind and smbtorture, as the cascading effect of a talloc_free() ensures that anything derived from the top level object is destroyed on disconnect. (This used to be commit 76d0b8206ce64d6ff4a192979c43dddbec726d6e)

2007-10-10r2625: use talloc_p, not talloc when possible (when allocating a structure ↵Andrew Tridgell1-1/+1

2007-10-10r2624: - save some system calls by only trying read/write operations that ↵Andrew Tridgell1-1/+11
