2007-10-10r15162: Patch for bug #3668. Windows has a bug with LARGE_READXJeremy Allison1-1/+5
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)

2001-08-27started converting NTSTATUS to be a structure on systems with gcc in order ↵Andrew Tridgell1-4/+5
to make it type incompatible with BOOL so we catch errors sooner. This has already found a number of bugs (This used to be commit 1b778bc7d22efff3f90dc450eb12baa1241cf68f)

2001-08-10A rewrite of the error handling in the libsmb client code. I've separatedTim Potter1-10/+14
out the error handling into a bunch of separate functions rather than all being handled in one big function. Fetch error codes from the last received packet: void cli_dos_error(struct cli_state *cli, uint8 *eclass, uint32 *num); uint32 cli_nt_error(struct cli_state *); Convert errors to UNIX errno values: int cli_errno_from_dos(uint8 eclass, uint32 num); int cli_errno_from_nt(uint32 status); int cli_errno(struct cli_state *cli); Detect different kinds of errors: BOOL cli_is_dos_error(struct cli_state *cli); BOOL cli_is_nt_error(struct cli_state *cli); BOOL cli_is_error(struct cli_state *cli); This also means we now support CAP_STATUS32 as we can decode and understand NT errors instead of just DOS errors. Yay! Ported a whole bunch of files in libsmb to use this new API instead of the just the DOS error. (This used to be commit 6dbdb0d813f3c7ab20b38baa1223b0b479aadec9)

2001-06-21next_token() was supposed to be a reentrant replacement for strtok(),Andrew Tridgell1-5/+8
but the code suffered from bitrot and is not now reentrant. That means we can get bizarre behaviour i've fixed this by making next_token() reentrant and creating a next_token_nr() that is a small non-reentrant wrapper for those lumps of code (mostly smbclient) that have come to rely on the non-reentrant behaviour (This used to be commit 674ee2f1d12b0afc164a9e9072758fd1c5e54df7)
2001-06-05Set correct reply word in large writeX (greater than 64k) replies.Jeremy Allison1-1/+5
Also added smbtorture test for this. Jeremy. (This used to be commit 6d65556ae8bea45a203defaded8436cbb56965e1)
2000-08-01Tidyup removing many of the 0xC0000000 | NT_STATUS_XXX stuff (only need ↵Jeremy Allison1-2/+2
NT_STATUS_XXX). Removed IS_BITS_xxx macros as they were just reproducing "C" syntax in a more obscure way. Jeremy. (This used to be commit c55bcec817f47d6162466b193d533c877194124a)
2000-04-25split clientgen.c into several partsAndrew Tridgell1-0/+273
the next step is splitting out the auth code, to make adding lukes NTLMSSP support easier (This used to be commit 10c5470835b43116ed48b3137c3b9cc867a20989)
