as said in title, wine fails to launch any windows programs.
here is the trace from one:

i'm not sure why it's complaining about a "noexec filesystem", nor how to fix this (i've tried both wine, and wine-proton, both with similar results.)
help is appreciated

| Afaik the"noexec" bit is just an assumption that wine makes (thus the question mark) and it can be blocked by something else. In this case I'd suspect selinux, but I never used it nor know much about so I can't really help with that. |

whilst SElinux is installed, it is currently in permissive mode (fresh install), so i don't think that it's causing the problem |

| Ok, double checked, definitely not SElinux. re-compiled a kernel with none of the major LSMs (SElinux, SMACK, TOMOYO, APPARMOUR etc). same error. |

did some digging around the wine source code (relevant file). the thing generating the error is:
| Code: |
if (!set_vprot( view, ptr + sec->VirtualAddress, size, vprot ) && (vprot & VPROT_EXEC))
ERR( "failed to set %08x protection on %s section %.8s, noexec filesystem?\n",
(int)sec->Characteristics, debugstr_w(filename), sec->Name );
|
which calls set_vprot:
| Code: |
/***********************************************************************
* set_vprot
*
* Change the protection of a range of pages.
*/
static BOOL set_vprot( struct file_view *view, void *base, size_t size, BYTE vprot )
{
if (view->protect & VPROT_WRITEWATCH)
{
/* each page may need different protections depending on write watch flag */
set_page_vprot_bits( base, size, vprot & ~VPROT_WRITEWATCH, ~vprot & ~VPROT_WRITEWATCH );
mprotect_range( base, size, 0, 0 );
return TRUE;
}
if (enable_write_exceptions && is_vprot_exec_write( vprot )) vprot |= VPROT_WRITEWATCH;
if (mprotect_exec( base, size, get_unix_prot(vprot) )) return FALSE;
set_page_vprot( base, size, vprot );
return TRUE;
}
|
the only thing in here that returns FALSE (thus tripping the error message is mprotect_exec:
| Code: |
static inline int mprotect_exec( void *base, size_t size, int unix_prot )
{
if (force_exec_prot && (unix_prot & PROT_READ) && !(unix_prot & PROT_EXEC))
{
TRACE( "forcing exec permission on %p-%p\n", base, (char *)base + size - 1 );
if (!mprotect( base, size, unix_prot | PROT_EXEC )) return 0;
/* exec + write may legitimately fail, in that case fall back to write only */
if (!(unix_prot & PROT_WRITE)) return -1;
}
return mprotect( base, size, unix_prot );
}
|
which is calling mprotect.
60000020 protection corresponds to (as taken from winnt.h):
| Code: |
IMAGE_SCN_CNT_CODE 0x00000020
IMAGE_SCN_MEM_EXECUTE 0x20000000
IMAGE_SCN_MEM_READ 0x40000000
|
based on the get_unix_prot function, the corresponding flags for mprotect are READ and EXECUTE
this fails for some reason.
any help figuring this out is appreciated (and sorely needed) |

fwiw does it work if you create the wine prefix on an entirely different filesystem?
e.g. tmpfs rather than btrfs, preferably without any special flags -- even seclabel just in case unless that's forced (hardly know selinux), and esp. not noexec so don't use /dev/shm as your trial tmpfs
btrfs in itself shouldn't cause issues for wine but I do suspect there's some configuration being set somewhere that's causing problems, maybe even some protection setting set at filesystem creation? I don't know the things that btrfs can do well. If tmpfs fails too, then could at least rule out that it's specific to that btrfs filesystem (assuming it's even what was being used like Hu pointed) |

just tried this based on code from here
modified as such:
| Code: |
-if (mprotect(buffer + pagesize * 2, pagesize, PROT_READ) == -1) handle_error("mprotect");
+if (mprotect(buffer + pagesize * 2, pagesize, PROT_READ | PROT_EXEC) == -1) handle_error("mprotect");
|
the program does not raise any error about mprotect, so it seems to be working.
the file permissions for the above mentioned mountmgr.sys (in the relevant prefix) are "-rw-r--r--". i've tried adding execute permissions, it doesn't help.
the prefix is located on the btrfs @home subvolume, so i assume those are the relevant mount options
will try to map the specific wine file next, and see if that still fails |

ok, wrote this short program. loading the file, and doing mprotect on it seems to succeed just fine (if i've written the program wrong, let me know)
| Code: |
#include <malloc.h>
#include <signal.h>
#include <stdio.h>
#include <stdlib.h>
#include <sys/mman.h>
#include <unistd.h>
#define handle_error(msg) \
do { perror(msg); exit(EXIT_FAILURE); } while (0)
static char *buffer;
int main(int argc, char ** argv)
{
int pagesize;
if (argc !=2)
{
printf("use: test [FILENAME]\n");
exit(EXIT_FAILURE);
}
FILE *f = fopen(argv[1], "rb");
fseek(f, 0, SEEK_END);
long fsize = ftell(f);
rewind(f);
pagesize = sysconf(_SC_PAGE_SIZE);
if (pagesize == -1)
handle_error("sysconf");
long file_pages = fsize/pagesize + (fsize % pagesize != 0); //round file pages up to closest integer
buffer = memalign(pagesize, file_pages * pagesize);
if (buffer == NULL)
handle_error("memalign");
printf("Start of region: %p\n", buffer);
fread(buffer, fsize, 1, f);
if (mprotect(buffer + pagesize * 2, pagesize,
PROT_READ | PROT_EXEC) == -1)
handle_error("mprotect");
printf("file mprotect succeeded!\n");
exit(EXIT_SUCCESS);
}
|
ran it with:
| Code: |
./test /home/{USER REDACTED}/Downloads/npp.8.2.portable.x64/pfx/drive_c/windows/system32/drivers/mountmgr.sys
|
(i'm using notepad++ as a test application), this location is on the BTRFS @home subvolume)
one note: wine seems to be mprotecting just the .text sections of the file, not the whole file (based on the error message that wine gives). not sure if that matters
edit note: mapping as write+exec works too (though wine maps as read+exec)

tried it on a USB formatted to ext4, with following mount options:

/dev/sdd1 on /mnt type ext4 (rw,relatime,seclabel)

(seclabel is forced, but it doesn't seem to do anything:

I see, odd...
If I create a wineprefix on an actual noexec filesystem, the errors I get are a bit different (none of the "section" stuff): | Code: | | 00f8:err:virtual:map_file_into_view failed to set PROT_EXEC on file map, noexec filesystem? |
Still no real idea why it's reaching that other error for you.
I don't think we've seen emerge --info yet? Is it a typical wine build with gcc + "-march=native -O2" or is there some special *FLAGS, clang/lld, or such involved? Given selinux I'm gonna guess it's a hardened profile that sets extras, but if hardened profiles broke wine I think we'd know by now (not that I tried).

| I think that test program is incorrect. You open and read the file, but then memalign allocates heap memory, and you adjust the permissions on that heap memory. This tells us nothing about whether you could change the protection of the mapping of the file. I think you need to open the file with open, map some or all of it with mmap, then use mprotect to change the protection on the mapping from mmap. |

new test program (based on this):
| Code: |
#include <fcntl.h>
#include <stdio.h>
#include <stdlib.h>
#include <sys/mman.h>
#include <sys/stat.h>
#include <sys/types.h>
#include <unistd.h>
#define handle_error(msg) \
do { perror(msg); exit(EXIT_FAILURE); } while (0)
int
main(int argc, char *argv[])
{
int fd;
char *addr;
off_t offset, pa_offset;
size_t length;
ssize_t s;
struct stat sb;
if (argc < 3 || argc > 4) {
fprintf(stderr, "%s file offset [length]\n", argv[0]);
exit(EXIT_FAILURE);
}
fd = open(argv[1], O_RDONLY);
if (fd == -1)
handle_error("open");
if (fstat(fd, &sb) == -1) /* To obtain file size */
handle_error("fstat");
offset = atoi(argv[2]);
pa_offset = offset & ~(sysconf(_SC_PAGE_SIZE) - 1);
/* offset for mmap() must be page aligned */
if (offset >= sb.st_size) {
fprintf(stderr, "offset is past end of file\n");
exit(EXIT_FAILURE);
}
if (argc == 4) {
length = atoi(argv[3]);
if (offset + length > sb.st_size)
length = sb.st_size - offset;
/* Can't display bytes past end of file */
} else { /* No length arg ==> display to end of file */
length = sb.st_size - offset;
}
addr = mmap(NULL, length + offset - pa_offset, PROT_READ,
MAP_PRIVATE, fd, pa_offset);
if (addr == MAP_FAILED)
handle_error("mmap");
if (mprotect(addr, length + offset - pa_offset,
PROT_WRITE | PROT_EXEC) == -1)
handle_error("mprotect");
else printf("mprotect success!\n");
s = write(STDOUT_FILENO, addr + offset - pa_offset, length);
if (s != length) {
if (s == -1)
handle_error("write");
fprintf(stderr, "partial write");
exit(EXIT_FAILURE);
}
munmap(addr, length + offset - pa_offset);
close(fd);
exit(EXIT_SUCCESS);
}
|
everything works fine. mprotect executes and returns without erroring.
executed as:
| Code: |
./test_mmap ~/Downloads/npp.8.7.portable.x64/pfx/drive_c/windows/system32/drivers/mountmgr.sys 0

i can't seem to install my video drivers (nvidia-drivers) when using a dist kernel. would chrooting from a liveUSB be an adequate substitute for this test? (i'm also happy to post the .config file, if that would help) |
