* Fix clang warnings on architectures with a 64-bit longTheodore Ts'o2021-02-111-13/+22
| | | | | | | | | | | | On most systems where we compile e2fsprogs, the u64 type is an unsigned long long. However, there are platforms (such as the PowerPC) where a long 64-bits and so u64 is typedef'ed to be unsigned long instead of a unsigned long long. Fix this by using explicit casts in printf statements. For scanf calls, we need to receive the value into a unsigned long long, and then assign it to a u64, after doing range checks.

* e2fsck: consistently use ext2fs_get_mem()Andreas Dilger2020-03-041-4/+2
| | | | | | | | | | | | | | | | Consistently use ext2fs_get_mem() and ext2fs_free_mem() instead of calling malloc() and free() directly in e2fsck. In several places it is possible to use ext2fs_get_memzero() instead of explicitly calling memset() on the memory afterward. This is just a code cleanup, and does not fix any specific bugs.

* e2fsck: generalize ea_refcountTahsin Erdogan2017-07-041-76/+84
| | | | | | | | | Currently ea_refcount is only used to track ea block refcounts. By generalizing it, we could use it for ea quota tracking and also ea_inode refcounts. Signed-off-by: Tahsin Erdogan <tahsin@google.com> Signed-off-by: Theodore Ts'o <tytso@mit.edu>
* e2fsck: fix printf conversion specs in ea_refcount.cEric Whitney2013-12-241-10/+11
| | | | | | | | | | | | Commit 130e961a6fb9d38997c83c6397cf9ddb5ed2491f changed the type used to represent block numbers in ea_refcount.c from blk_t to blk64_t to add support for 64 bit extended attribute refcounting. We also need to adjust printf conversion specs that now don't match their new blk64_t arguments. This will silence compiler warnings seen when "make check" is run and will avoid truncation of printed values.

* e2fsck: add support for 64-bit extended attribute block refcountingTheodore Ts'o2013-12-021-9/+9
| | | | | | | | | If we have a 64-bit file system with extended attribute blocks, e2fsck would not correctly handle EA blocks that were located beyond the 32-bit block number boundary. Fix this by teaching e2fsck/ea_refcount.c to use 64-bit block numbers. Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
* e2fsck: simplify binary search in ea_refcount.cTheodore Ts'o2011-09-301-26/+0
| | | | | | | Remove the interpolation search in ea_refcount. The added complexity isn't worth the speed up. Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
* misc: quiet minor compiler errorsAndreas Dilger2011-09-241-16/+14
| | | | | | | | | | | Several compiler errors are quieted: - zero-length gnu_printf format string - unused variable - uninitalized variable (though it isn't actually used for anything) - fixed a bug in ext2fs_stat() if stat64() does not exist Signed-off-by: Andreas Dilger <adilger@whamcloud.com> Signed-off-by: Theodore Ts'o <tytso@mit.edu>
* Shorten compile commands run by the build systemTheodore Ts'o2011-09-181-0/+1
| | | | | | | | | | | | | | | The DEFS line in MCONFIG had gotten so long that it exceeded 4k, and this was starting to cause some tools heartburn. It also made "make V=1" almost useless, since trying to following the individual commands run by make was lost in the noise of all of the defines. So fix this by putting the configure-generated defines in lib/config.h and the directory pathnames to lib/dirpaths.h. In addition, clean up some vestigal defines in configure.in and in the Makefiles to further shorten the cc command lines. Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
* e2fsck, resize2fs: fix a fp precision error that can lead to a seg faultTheodore Ts'o2010-07-051-1/+6
| | | | | | | | | | | Commit 641b66b fixed a floating point precision error which can result in a search algorithm looping forever. It can also result in an array index being out of bounds and causing a segfault. Here are two more cases in e2fsck and resize2fs that need to be fixed. I've just used the same fix from the that commit. Signed-off-by: Lachlan McIlroy <lmcilroy@redhat.com> Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
