2009-04-06Convert cli_read_andx to tevent_reqVolker Lendecke1-108/+150
2009-03-12Revert "s3:libsmb: add an option to cli_push to let the caller provide the ↵Stefan Metzmacher1-25/+8
buffers" This reverts commit 9579a6f193f570e4ce2af80f4aac7c2f25ae5b22. It's confusing to have a boolean to alter the behavior of cli_push and as the new feature isn't used yet I revert it. We can readd a extra function later. metze

2009-03-10s3:libsmb: fix a lot of cli_push() bugsStefan Metzmacher1-95/+107
There were the following problems: 1.) if window_size was a multiple of the chunk_size, we silently dropped the last truncated chunk. 2.) if window_size was 0 pushed only the first chunk to the server and silently dropped the rest. 3.) we had only transferred state->num_reqs writes, even if there would be more data to send. metze
2009-02-02Next step disentangling async_req from NTSTATUSVolker Lendecke1-1/+1
Now I need to document this :-)
2009-02-01Split up async_req into a generic and a NTSTATUS specific partVolker Lendecke1-16/+16
2009-01-18Add a macro async_req_setup()Volker Lendecke1-25/+9
This streamlines setting up a multi-step async request a bit
2009-01-03struct async_req doesn't really need to carry an event_contextVolker Lendecke1-5/+5
2008-12-19Add async cli_write_andx and cli_pullVolker Lendecke1-0/+406
2008-12-19Pass "bytes_alignment" up through cli_request_sendVolker Lendecke1-1/+1
This parameter makes smb_spice_chain add padding before the bytes field
2008-12-19Factor out cli_write_max_bufsizeVolker Lendecke1-25/+36
2008-12-13For read&x replies, check the offsetVolker Lendecke1-0/+19
2008-12-08Simplify async programming a bit with helper routinesVolker Lendecke1-6/+5
Introduce async_req_is_error() and async_req_simple_recv()
2008-10-14Use {u,}int64_t instead of SMB_BIG_{U,}INT.Jelmer Vernooij1-3/+3
2008-08-28Remove cli_request_get()Volker Lendecke1-4/+8
req->private_data==NULL at this point is definitely a bug. (This used to be commit ce3dc9f616cafc1289a94ac7cae0beca967d836e)
2008-08-28Add cli_pull_replyVolker Lendecke1-5/+12
Along the lines of cli_request_send this abstracts away the smb-level buffer handling when parsing replies we got from the server. (This used to be commit 253134d3aaa359fdfb665709dd5686f69af7f8fd)
2008-08-28Remove cli->event_ctx, pass it explicitlyVolker Lendecke1-9/+24
Storing the event_context as permanent state in struct cli_state creates more complex code than necessary IMO. (This used to be commit debb37f703075008e5ea7d34d214cfa4d0f8f916)
2008-08-28Refactoring: Add the routine cli_request_send()Volker Lendecke1-46/+25
cli_request_send() is supposed to bundle all generic SMB-header handling. This makes cli_request_new static to async_smb.c. (This used to be commit 7e73dd4e7622db64d30d48ba106892e0895fc188)
2008-08-23Revert "Protect against short read&x replies"Volker Lendecke1-4/+0

2008-03-21On Solaris, size_t seems to be only 32 bit.Volker Lendecke1-5/+7
Fix bug 5341, thanks a lot to Karoly Vegh for testing it! Volker (This used to be commit 19eb8c9316b10b1277121e90d0d3ef50ee562118)
2008-03-19!NT_STATUS_IS_OK != NT_STATUS_IS_ERRVolker Lendecke1-1/+1
When reading from a pipe, Windows return STATUS_BUFFER_OVERFLOW which is *not* an error. (This used to be commit 24018d882d1b1cfece47c533fe5bbca91de124cc)
2008-03-18Fix bug 5334Volker Lendecke1-0/+8
I did not test with a zero length file :-) (This used to be commit 7d7a73944c2dcf078f7bc8de65d575f32f9aa851)

2008-03-06Convert cli_read to use cli_pullVolker Lendecke1-163/+15
(This used to be commit d69b20111a849152a7d9108763207c813bf9068b)
2008-03-06Add async cli_pull supportVolker Lendecke1-0/+425
This is the big (and potentially controversial) one. It took a phone call to explain to metze what is going on inside cli_pull_read_done, but I would really like everybody to understand this function. It is a very good and reasonably complex example of async programming. If we want more asynchronism in s3, this is what we will have to deal with :-) Make use of it in the smbclient "get" command. Volker (This used to be commit 76f9b360ee1d973630d82d401eeddce858189301)
2008-01-16Fix bug found by Derrell - windows returns an read returnJeremy Allison1-21/+28

Jeremy. (This used to be commit 47640fb20e42f226e7ea104076fd52547bfe1abb)
2007-11-02Change the client library to write directly out ofJeremy Allison1-32/+74
the incoming buffer in the non-signed case. Speeds up writes by over 10% or so. Complete the server recvfile implementation. Jeremy. (This used to be commit 81ca5853b2475f123faab3b550f0a7b24ae3c208)
2007-10-30Our userlevel SMBwriteX call is non-standard in that itJeremy Allison1-8/+10
sometimes uses a 12-word write and doesn't include a pad byte (as Windows does). Fix this so that we are identical to Windows clients. This will make recvfile processing much easier to detect (as we can just read a standard writeX header length to decide). Jeremy. (This used to be commit 3d3d1b806aef3617abaac46daf230ed32076e2ce)
2007-10-18RIP BOOL. Convert BOOL -> bool. I found a few interestingJeremy Allison1-7/+7
bugs in various places whilst doing this (places that assumed BOOL == int). I also need to fix the Samba4 pidl generation (next checkin). Jeremy. (This used to be commit f35a266b3cbb3e5fa6a86be60f34fe340a3ca71f)

2007-10-10r22920: Add in the UNIX capability for 24-bit readX, as discussedJeremy Allison1-10/+40
with the Apple guys and Linux kernel guys. Still looking at how to do writeX as there's no recvfile(). Jeremy. (This used to be commit a53268fb2082de586e2df250d8ddfcff53379102)
2007-10-10r22391: Looks bigger than it is. Make "inbuf" availableJeremy Allison1-5/+5
to all callers of smb_setlen (via set_message() calls). This will allow the server to reflect back the correct encryption context. Jeremy. (This used to be commit 2d80a96120a5fe2fe726f00746d36d85044c4bdb)

where if you ask for exactly 64k bytes it returns 0. Jeremy. (This used to be commit dcef65acb5bc08ea4b61ef490a518b7e668ff2ee)
2007-10-10r13915: Fixed a very interesting class of realloc() bugs found by Coverity.Jeremy Allison1-1/+6
realloc can return NULL in one of two cases - (1) the realloc failed, (2) realloc succeeded but the new size requested was zero, in which case this is identical to a free() call. The error paths dealing with these two cases should be different, but mostly weren't. Secondly the standard idiom for dealing with realloc when you know the new size is non-zero is the following : tmp = realloc(p, size); if (!tmp) { SAFE_FREE(p); return error; } else { p = tmp; } However, there were *many* *many* places in Samba where we were using the old (broken) idiom of : p = realloc(p, size) if (!p) { return error; } which will leak the memory pointed to by p on realloc fail. This commit (hopefully) fixes all these cases by moving to a standard idiom of : p = SMB_REALLOC(p, size) if (!p) { return error; } Where if the realloc returns null due to the realloc failing or size == 0 we *guarentee* that the storage pointed to by p has been freed. This allows me to remove a lot of code that was dealing with the standard (more verbose) method that required a tmp pointer. This is almost always what you want. When a realloc fails you never usually want the old memory, you want to free it and get into your error processing asap. For the 11 remaining cases where we really do need to keep the old pointer I have invented the new macro SMB_REALLOC_KEEP_OLD_ON_ERROR, which can be used as follows : tmp = SMB_REALLOC_KEEP_OLD_ON_ERROR(p, size); if (!tmp) { SAFE_FREE(p); return error; } else { p = tmp; } SMB_REALLOC_KEEP_OLD_ON_ERROR guarentees never to free the pointer p, even on size == 0 or realloc fail. All this is done by a hidden extra argument to Realloc(), BOOL free_old_on_error which is set appropriately by the SMB_REALLOC and SMB_REALLOC_KEEP_OLD_ON_ERROR macros (and their array counterparts). It remains to be seen what this will do to our Coverity bug count :-). Jeremy. (This used to be commit 1d710d06a214f3f1740e80e0bffd6aab44aac2b0)
