[PATCH 1/2] kernel32/tests: Add NtAllocateVirtualMemory tests for ZeroBits behavior
by Rémi Bernon May 24, 2019

May 24, 2019

The ZeroBits parameter doesn't behave as expected, and some 64bit code use it to allocate memory in the lower 32bit address space. The expected full behaviour is: * ZeroBits == 0: no constraint on address range * 0 < ZeroBits <= 15: returned address should have as many upper bits set to 0, starting at bit 31. In 64bit mode, upper 64bits should all be 0 as well. * 15 < ZeroBits <= 31: unsure, but probably same as ZeroBits == 15. * ZeroBits > 31: (64bit/WoW64 only) ZeroBits behaves as a bitmask, as if it was set to the number of leading 0 in the bitmask, works in the whole 64bit range.

[PATCH v2 1/2] ntdll/directory: Add support for EXT4 case folding per directory
by Gabriel Ivăncescu May 24, 2019

May 24, 2019

Wine-Bug: https://bugs.winehq.org/show_bug.cgi?id=47099 Signed-off-by: Gabriel Ivăncescu <gabrielopcode(a)gmail.com> --- v2: Fix mistake with fstatat return value. This patch just adds support for the case-insensitive attribute on ext4 with newer kernels -- so it should be safe for upstream (barring stylistic and other changes). It has some conditional processing for perf reasons. Checking for the EXT4_CASEFOLD_FL attribute involves an ioctl, which operates on file descriptors, while all the former checks operated directly on the dir name (e.g. statfs). Obviously, it's best to avoid looking up the directory multiple times (also for correctness, so it refers to the same dir). So in the case that we *do* use a file descriptor, then use it (e.g. fstatfs) everywhere. However, to avoid a perf regression or downgrade on systems that don't support the EXT2_IOC_GETFLAGS ioctl (e.g. MacOS, FreeBSD), we continue using statfs and the like directly, this shaves off two syscalls (open/close). But in the case the EXT4_CASEFOLD_FL is not supported on Linux (i.e. on current kernels) or the directory doesn't have it (think of dirs outside drive_c), this will unfortunately involve a bit more syscalls now, because it has to open() and close() the fd. I'd really like if the fstatfs and fstatat can stay if we do use the fd, to somehow make it less impactful on current systems, so they won't have to lookup the directory again. So that's basically why the GET_DIR_CASE_SENSITIVITY_USE_FD constant is there. One last thing: as it is now, on Linux, we always set the EXT4_CASEFOLD_FL flag ourselves since it does no harm even if it's not supported. Thus, I can of course remove the .ciopfs old code and keep just the fstatat() call by assuming we always use fd on Linux, if you prefer it that way. I didn't remove it because I didn't want to "hardcode" this assumption, so I'm waiting for feedback. dlls/ntdll/directory.c | 66 ++++++++++++++++++++++++++++++++++++++++-- 1 file changed, 63 insertions(+), 3 deletions(-) diff --git a/dlls/ntdll/directory.c b/dlls/ntdll/directory.c index bbdbbe9..e5fa48d 100644 --- a/dlls/ntdll/directory.c +++ b/dlls/ntdll/directory.c @@ -115,6 +115,8 @@ WINE_DEFAULT_DEBUG_CHANNEL(file); /* just in case... */ #undef VFAT_IOCTL_READDIR_BOTH +#undef EXT2_IOC_GETFLAGS +#undef EXT4_CASEFOLD_FL #ifdef linux @@ -130,6 +132,12 @@ typedef struct /* Define the VFAT ioctl to get both short and long file names */ #define VFAT_IOCTL_READDIR_BOTH _IOR('r', 1, KERNEL_DIRENT [2] ) +/* Define the ext2 ioctl for handling extra attributes */ +#define EXT2_IOC_GETFLAGS _IOR('f', 1, long) + +/* Case-insensitivity attribute */ +#define EXT4_CASEFOLD_FL 0x40000000 + #ifndef O_DIRECTORY # define O_DIRECTORY 0200000 /* must be directory */ #endif @@ -977,6 +985,25 @@ static char *get_device_mount_point( dev_t dev ) } +/*********************************************************************** + * get_dir_case_sensitivity_ioctl + * + * Checks if the specified directory is case sensitive or not.

Syscall thunks in ntoskrnl
by Derek Lesho May 24, 2019

May 24, 2019

Hello, I have written some prototype patches that allow EasyAntiCheat.sys's syscall scanner to succeed, but the aren't clean and I'd like some direction on which path I should take for the patch I end up submitting here. Somebody on github has gone through the effort of reverse engineering this check already, and you can find that code here: https://github.com/adrianyy/EACReversing/blob/master/EasyAntiCheat.sys/serv… As you can see, the driver reads a ntoskrnl's Zw* syscall export, replaces the syscall id operand with the one it found from reading ntdll, and scans the section for the right appropriate Zw function. For this to work, we need to have the ids from the syscall thunks that exist in ntdll (on staging from the fake-dlls patchset) match the ids in the thunks we add for the Zw* functions in ntoskrnl. There are a couple ways of doing this, at first I manually put in the assembly to see if it would work, and it did, but that's a clean solution. My current solution adds all Zw exports from ntdll.spec to ntoskrnl.exe.spec and has winebuild generate the exports in alphabetical order, but this solution requires that ntdll.spec and ntoskrnl.exe.spec be kept in sync, which I'm not sure is a good idea. Another solution I thought of is having a syscall table be read by winebuild, so that ntoskrnl and ntdll can export different syscall numbers and still share the same ids, but maybe this is over-engineering the problem. Thank you all for your input!
