2024-02-18Make it possible to compile mkfs.ubifs without zlibDavid Oberhollenzer
This one is a bit trickier than adding WITH_ZLIB ifdefs. Some parts of the code assume that zlib is always present and have complicated fallback behavior. Particularly the "favor_lzo" compression method that uses either zlib or lzo, whichever produces the better result. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2024-02-15Cleanup handling of optional dependenciesDavid Oberhollenzer
Don't use super pedantic parsing of the argument and work with the generated variable instead of assigning it to our own and set it to "check" if not value is assigned. Then search for a dependency if the with variable is anything other than "no" and fail if it was set to "yes". In addition, the WITHOUT_xxx defines are replaced with WITH_xxx defines.

2023-12-19mkfs.ubifs: fix xattr scanning for builds with selinux supportDavid Oberhollenzer
mkfs.uibfs can add Selinux xattrs from a labeling file using libselinux to parse it. The commit that added this feature simply introduced a separate function, inode_add_selinux_xattr, which is called instead of inode_add_xattr. If no --selinux argument is specified for mkfs.ubifs, this is a no-op. The problem is, that this breaks xattr scanning for any build with Selinux enabled. The Selinux version is always called and it does not scan for xattrs on the filesystem, or dispatch to the original. This commit fixes the xattr scanning behavior. We unconditionally call both functions (they each have no-op implementations if the feature is missing) and in the regular xattr scanning code, we skip selinux attributes, if the --selinux option was given.

2020-09-23mkfs.ubifs: Fix build with SELinuxBastian Germann
In v2.1.0, SELinux support was introduced. It never compiled with ubifs because it uses the old add_xattr signature that also changed in v2.1.0 with a1bd316e23("mkfs.ubifs: Implement fscrypto context store as xattr"). Add the ubifs_ino_node and name to the call and remove the nm that is contructed in the new function version.

2020-02-09mkfs.ubifs: fix broken build if fscrtyp is disabledDavid Oberhollenzer
First, there is no option named of X509_OPTION. It was presumably changed during development to AUTH_CERT_OPTION. This commit fixes the name in the !WITH_CRYPTO branch. Similarly, '}' got moved into the WITH_CRYPTO branch, but not into else branch, resulting in tons of errors if fscrypt is disabled. This commit pulls it back out of both branches.

2019-08-19mkfs.ubifs: Add authentication supportSascha Hauer
This adds support for authenticated UBIFS images. In authenticated images all UBIFS nodes are hashed as described in the UBIFS authentication whitepaper. Additionally the superblock node contains a hash of the master node and itself is cryptographically signed in a node following the superblock node. The signature is in PKCS #7 CMS format. To generate an authenticated image these options are necessary: --hash-algo=NAME hash algorithm to use for signed images (Valid options include sha1, sha256, sha512) --auth-key=FILE filename or PKCS #11 uri containing the authentication key for signing --auth-cert=FILE Authentication certificate filename for signing.

The image2 column denotes the results for the same image but with .deb files removed. The time column contains the output of the run time of the command. ZSTD's compression level three is currently default. Based on the compression results (for the default level) it outperforms LZO in run time and compression and is almost as good as ZLIB in terms of compression but quicker. The higher compression levels make almost no difference in compression but take a lot of time. The compression level used is the default offered by ZSTD. It does not make sense the higher levels.

2019-04-03mkfs.ubifs: fix regression when trying to store device special filesDavid Oberhollenzer
Commit a767dd30 added a check to add_inode that bails when trying to store extra data in anything other than a symlink. The symlink encryption support added by that commit relies on the assumption. Unfortionately it was overlooked that device special files also store the device number as additional data in the inode. The check added in commit a767dd30 broke support for device files in mkfs.ubifs. This commit adds a quick and dirty fix, moving the check into the fscrypt branch, breaking only the fscrypt version but restoring old functionality for unencrypted file systems.

2019-02-11mtd-utils: fixes double free in mkfs.ubifsYufen Yu
In inode_add_xattr(), it malloc a buffer for name, and then passes the bufffer ptr to add_xattr(). The ptr will be used to create a new idx_entry in add_to_index(). However, inode_add_xattr() will free the buffer before return. which can cause double free in write_index(): free(idx_ptr[i]->name) *** Error in `./mkfs.ubifs': double free or corruption (fasttop): 0x0000000000aae220 *** ======= Backtrace: ========= /lib64/libc.so.6(+0x7cbac)[0x7f4881ff5bac] /lib64/libc.so.6(+0x87a59)[0x7f4882000a59] /lib64/libc.so.6(cfree+0x16e)[0x7f48820063be] ./mkfs.ubifs[0x402fbf] /lib64/libc.so.6(__libc_start_main+0xea)[0x7f4881f9988a] ./mkfs.ubifs[0x40356a] Signed-off-by: Yufen Yu <yuyufen@huawei.com> Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>

2018-10-02mkfs.ubifs: Fix xattr nlink valueSascha Hauer
The nlink value of a xattr node must always be one, it has nothing to do with the nlink value of the inode the attribute belongs to. The bug can be observed when mounting a mkfs.ubifs generated image which contains xattrs on directories or files with hardlinks to them. When mounting such an image with chk_fs = 1 it fails with: UBIFS error (ubi0:0 pid 1833): dbg_check_filesystem: inode 3308 nlink is 3, but calculated nlink is 1 Another bug that can be triggered is an assertion in ubifs_xattr_remove() which assures that the xattr i_nlink count should be one when the xattr is removed.
