[Bug 37133] New: Clang Static Analyzer: Null path

https://bugs.winehq.org/show_bug.cgi?id=37133 Bug ID: 37133 Summary: Clang Static Analyzer: Null path Product: Wine Version: 1.7.22 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown Assignee: wine-bugs(a)winehq.org Reporter: lukebenes(a)hotmail.com Clang Static Analyzer identifies Null path File: dlls/crypt32/rootstore.c Location: line 413, column 10 Description: Null pointer passed as an argument to a 'nonnull' parameter static BOOL import_certs_from_path(LPCSTR path, HCERTSTORE store, BOOL allow_dir) { ... fd = open(path, O_RDONLY); //Clang: Null pointer passed as //an argument to a 'nonnull' parameter ... } To understand why Clang suspects that NULL may get here, let's examine the fragment where this function is called: static BOOL import_certs_from_dir(LPCSTR path, HCERTSTORE store) { ... char *filebuf = NULL; //Clang: 'filebuf' initialized to a null pointer value struct dirent *entry; while ((entry = readdir(dir))) { ... size_t name_len = strlen(entry->d_name); //Calling function to change filebuf if (!check_buffer_resize(&filebuf, &bufsize, path_len + 1 + name_len + 1)) { ERR(...); break; } snprintf(filebuf, bufsize, "%s/%s", path, entry->d_name); if (import_certs_from_path(filebuf, store, FALSE) && !ret) //Clang: Passing null pointer value via 1st parameter 'path' //Clang: Calling 'import_certs_from_path' ret = TRUE; ... } } In this code, the check_buffer_resize function is called where either the value of the filebuf variable must change or FALSE must be returned; but the function may fail to change filebuf and return TRUE instead. Take a look at the function's code below: static BOOL check_buffer_resize(char **ptr_buf, size_t *buf_size, size_t check_size) { if (check_size > *buf_size) { ... *ptr_buf = CryptMemAlloc(*buf_size); ... } return TRUE; } The function contains only one condition where the ptr_buf variable is changed, and if this condition is false, the true return result will allow you to use this variable further on. A similar issue is with the memcpy() function: File: server/directory.c Location: line 548, column 21 Description: Null pointer passed as an argument to a 'nonnull' parameter -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 37132] New: Clang Static Analyzer: Uninitialized array item

HRESULT WINAPI AVISaveVW(....int nStreams ....) { ... //Declaring 8-item array, [0..7] PAVISTREAM pInStreams[MAX_AVISTREAMS]; ... if (nStreams >= MAX_AVISTREAMS) { WARN(...); return AVIERR_INTERNAL; } ... //Initializing first 7 items, [0..6]. for (curStream = 0; curStream < nStreams; curStream++) { pInStreams[curStream] = NULL; pOutStreams[curStream] = NULL; } ... for (curStream = 0; curStream < nStreams; curStream++) { ... if (curStream + 1 >= nStreams) { /* move the others one up */ PAVISTREAM *ppas = &pInStreams[curStream]; int n = nStreams - (curStream + 1); do { *ppas = pInStreams[curStream + 1]; //Clang: Assigned value is garbage or undefined } while (--n); } ... } ... } In this code, an array of 8 items is declared. The code will continue executing as long as the nStreams variable is less than 8, i.e. 7 at most. All the loops in this function with the conditional statement (curStream < nStreams) fail to iterate through the last item, both before its initialization and when using it. The line Clang displayed the message on is just that very line where the eighth item with the index 7 is taken, as the (curStream + 1 >= nStreams) condition will be true at curStream==6 and nStreams==7. Addressing the pInStreams[curStream + 1] array will give us the last, previously uninitialized item. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

All of these features have the msidbFeatureAttributesUIDisallowAbsent attribute set, which makes me believe that it is supposed to override the level. If these features are not installed the application fails to start with an error message requesting reinstallation as Resources.dll is missing. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

http://bugs.winehq.org/show_bug.cgi?id=36853 Bug ID: 36853 Summary: WINE should detect the presence of the window manager. Product: Wine Version: unspecified Hardware: x86 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: programs Assignee: wine-bugs(a)winehq.org Reporter: carlo.bramix(a)libero.it Created attachment 48943 --> http://bugs.winehq.org/attachment.cgi?id=48943 Screenshot, missing decorations. In my private, ubuntu based, linux distribution, I installed the strict minimun amount of packages, required for running just WINE and applications for Windows with few megabytes. I have not installed a window manager. When running applications, it will happen that the decorations of the windows won't be displayed if the window manager is enabled to draw or control them. See the attached screenshot with winecfg running as an example. The presence of the window manager should be detected and, if it is not available, the two options for such purpose should be always grayed and the function must be disabled automatically if it's enabled. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

With the value 21, the 'i' variable will be first incremented by one and then decremented by one.
