| * lib/uuid: remove unneeded Windows UUID workaroundEric Biggers2023-01-304-19/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some .c files in lib/uuid/ contain the following: #ifdef _WIN32 #define _WIN32_WINNT 0x0500 #include <windows.h> #define UUID MYUUID #endif This seems to have been intended to allow the use of a local "UUID" type without colliding with "UUID" in the Windows API. However, this is unnecessary because there's no local "UUID" type -- there's only uuid_t. None of these .c files need the include of windows.h, either. Finally, the unconditional definition of _WIN32_WINNT causes a compiler warning when the user defines _WIN32_WINNT themself. Since this code is unnecessary and is causing problems, just remove it.

| | | | | | | | | | | | | | | | | | | | | | | | | | -Werror wasn't actually being used when building the libraries, as the libraries use CFLAGS_STLIB instead of CFLAGS. Use CFLAGS_WARN, which gets included in both. Note: -Werror can't just be passed to 'configure' like the other flags are, as it interferes with some of the configure checks.

| * Change the xattr entry hash to use an unsighed char by defaultTheodore Ts'o2023-01-299-15/+102
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Starting in Linux 6.2, char is forced to always unsigned when compiling the kernel, even on those platforms (such as x86) where char was traditionally signed. This exposed a bug in ext4, where when calculating the extended attribute entry hash, we used a char value from the extended attribute name. This resulted with the entry hash, which is stored on-disk, to variable depending on whether the plaform used a signed or unsigned char. Fortunately, the xattr names tend to be ASCII characters with the 8th bit zero, so it wasn't noticed two decades (this bugs dates back to the introduction of extended attribute support to ext2 in 2.5.46). However, when this change was made in v6.2-rc1, the inconsistency between the extended attribute hash calculated by e2fsprogs (which was still using a signed char on x86) was different from an x86 kernel, and this triggered a test failure in generic/454. This was fixed in kernel commit f3bbac32475b (" ext4: deal with legacy signed xattr name hash values"), where Linus decreed that it wasn't worth it to fix this the same way we had addressed has used by the dir_index feature. Instead, starting in the 6.2 kernel, ext4 will accept both the hash calculated using signed and unsigned chars, but set the entry hash using the unsigned char. This commit makes e2fsprogs follow suit. Signed-off-by: Theodore Ts'o <tytso@mit.edu>

| * e2fsck: double cast a pointer to suppress a bogus compiler warning in kfree()Theodore Ts'o2023-01-271-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The C standard is wrong[1] with respect to the function signature of free(), while the kernel's kfree() is correct. Unfortunately, this leads to compiler warnings. Sayeth Dennis Ritchie: "Noalias must go. This is non-negotiable"[2]. Noalias went. The confusion around const, alas, still remains.

| * e2fsck: use ext2_ino_t instead of ino_tTheodore Ts'o2023-01-273-11/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The ino_t type is defined by the system header files, and may be anything from an unsigned int, unsigned long, or an unsigned long long. So where we are referring to an ext2/ext3/ext4 inode number, we should use ext2_ino_t to avoid this ambiguity, especially when passing an inode number to a printf-style function. This was detected via a compiler warning on MacOS, but it's potentially a real bug, since it can cause an error message to print a garbled inode number. Signed-off-by: Theodore Ts'o <tytso@mit.edu>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | search_sysfs_block() is causing -Wformat-truncation warnings. These could be fixed by checking the return value of snprintf(), instead of doing buggy checks like 'strlen(p_de->d_name) > SYSFS_PATH_LEN - strlen(path) - 32', which has an integer underflow bug. However, the only purpose of search_sysfs_block() is to find the sysfs directory for a block device by device number. That can trivially be done using /sys/dev/block/$major:$minor. So just do that instead. Also make get_partition_start() explicitly Linux-only, as it has never worked anywhere else.

| * config/install-sh: update to latest versionEric Biggers2023-01-271-190/+493
| | | | | | | | | | | | | | | | | | | | | | | | The version of install-sh in the source tree is extremely old and doesn't work when passed multiple path arguments, which breaks 'make install' on macOS. Therefore, delete this file and run 'autoreconf -i' to update it to the latest version. Signed-off-by: Eric Biggers <ebiggers@google.com> Signed-off-by: Theodore Ts'o <tytso@mit.edu>

| | | | | | | | | | | | | | | | | | Since the include/mingw/ directory needs to be on the include path when building for Windows with MinGW, add it to INCLUDES automatically, and AC_DEFINE the corresponding HAVE_*_H constants.

| | | | | | | | | | | | | | | | The tdb support does not build for Windows, due to the use of various UNIX-isms, so disable it by default when building for Windows. Signed-off-by: Eric Biggers <ebiggers@google.com> Signed-off-by: Theodore Ts'o <tytso@mit.edu>

| | | | | | | | | | | | | | | | | | | | | | | | Cygwin and MSYS2 are UNIX-compatible platforms on top of Windows, so they should use the UNIX I/O manager, not the Windows I/O manager. (Note that "cygwin" was misspelled as "cigwin", so the code did not have the intended effect anyway.)

| * mmp: fix wrong comparison in ext2fs_mmp_stoplihaoxiang (F)2023-01-261-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In our knowledge, ext2fs_mmp_stop use to process the rest of work when mmp will finish. Critically, it must check if the mmp block is not changed. But there exist an error in comparing the mmp and mmp_cmp. Look to ext2fs_mmp_read, the assignment of mmp_cmp retrieve from the superblock of disk and it copy to mmp_buf if mmp_buf is not none and not equal to mmp_cmp in the meanwhile. However, ext2fs_mmp_stop pass the no NULL pointer fs->mmp_buf which has possed the mmp info to ext2fs_mmp_read. Consequently, ext2fs_mmp_read override fs->mmp_buf by fs->mmp_cmp so that loss the meaning of comparing themselves after that and worse yet, couldn't judge whether the struct of mmp has changed. In fact, we only need to modify the parameter to NULL pointer for solving this problem. Signed-off-by: lihaoxiang <lihaoxiang9@huawei.com> Signed-off-by: Theodore Ts'o <tytso@mit.edu>
