* configure.ac: fix link with -llzmaFabrice Fontaine2023-03-061-4/+4
| | | | | | | | | | | | | | | | Add liblzma_LIBS to LIBS to avoid the following build failure when building with a static-only liblzma.a: /home/autobuild/autobuild/instance-5/output-1/host/lib/gcc/xtensa-buildroot-linux-uclibc/11.3.0/../../../../xtensa-buildroot-linux-uclibc/bin/ld: libkmod/.libs/libkmod-internal.a(libkmod-file.o):(.text.xz_uncompress+0x10): undefined reference to `lzma_code' For consistency, also update libzstd, zlib and libcrypto Fixes: - http://autobuild.buildroot.org/results/83a4a7ecc77f39639d3e5bc8554bd01a62a3ede0 References: https://github.com/kmod-project/kmod/pull/25 Signed-off-by: Fabrice Fontaine <fontaine.fabrice@gmail.com> Signed-off-by: Lucas De Marchi <lucas.de.marchi@gmail.com>
* configure: manage libkmod.pc.in and version.py.in via AC_CONFIG_FILESEmil Velikov2023-02-211-0/+2
| | | | | | | | | | | | | Replace the manual sed command, build rules and dist/clean for using AC_CONFIG_FILES. It does the exact same thing, with an added bonus... Currently we're missing version.py.in in the EXTRA_DIST. Thus a simple "touch Makefile" should retrigger the regeneration of version.py. Which would presumably fail, since the input file isn't in the distribution tarball.

| | | | | | | | | | | | | I changed the style of the hackargs variable in autogen.sh to multiline because said line was becoming a bit long with the new --with-zstd arg added. A previous version of this patch has been running on my two Arch Linux installations (with an accompanying mkinitcpio patch) for several months over many kernel updates without any issues. Any additional testing and/or patch review would of course be appreciated. Signed-off-by: Torge Matthies <openglfreak@googlemail.com>

* build: Stop using doltAdrian Bunk2019-02-201-1/+0
| | | | | | | | | | | | | This does regress "make -12" from 0.7s to 0.9s on my Coffee Lake machine, but even on slower hardware this will not amount to a noticable slowdown. On the other hand using dolt can create problems for people doing cross-compilation, e.g. Yocto has two hacks just for dolt in kmod: https://git.yoctoproject.org/cgit/cgit.cgi/poky/tree/meta/recipes-kernel/kmod/kmod.inc?id=a17abae00785c76cfffe5381a22fb2c86b982e82 (Lucas: remove leftover entry in Makefile and reformat commit message)
* Link against libcrypto, not all of opensslDave Reisner2019-02-131-2/+2
| | | | | | | | | | | | | | | | | | | | | | In the previous build setup, libkmod.so would link to not just libcrypto.so, but also libssl.so: $ readelf -d /lib/libkmod.so | grep NEEDED 0x0000000000000001 (NEEDED) Shared library: [liblzma.so.5] 0x0000000000000001 (NEEDED) Shared library: [libz.so.1] 0x0000000000000001 (NEEDED) Shared library: [libssl.so.1.1] 0x0000000000000001 (NEEDED) Shared library: [libcrypto.so.1.1] 0x0000000000000001 (NEEDED) Shared library: [libc.so.6] We don't need any symbols from libssl, though. This patch ensures that we pass 'libcrypto' to pkgconfig rather than 'openssl', getting only the library that we need: $ readelf -d ./libkmod/.libs/libkmod.so.2.3.4 | grep NEEDED 0x0000000000000001 (NEEDED) Shared library: [liblzma.so.5] 0x0000000000000001 (NEEDED) Shared library: [libz.so.1] 0x0000000000000001 (NEEDED) Shared library: [libcrypto.so.1.1] 0x0000000000000001 (NEEDED) Shared library: [libc.so.6]

* libkmod-signature: implement pkcs7 parsing with opensslYauheni Kaliuta2019-02-041-0/+11
| | | | | | | | | | | | | | | The patch adds data fetching from the PKCS#7 certificate using openssl library (which is used by scripts/sign-file.c in the linux kernel to sign modules). In general the certificate can contain many signatures, but since kmod (modinfo) supports only one signature at the moment, only first one is taken. With the current sign-file.c certificate doesn't contain signer key's fingerprint, so "serial number" is used for the key id. Signed-off-by: Yauheni Kaliuta <yauheni.kaliuta@redhat.com>

* build: cache modules from playgroundcached-modulesLucas De Marchi2015-05-311-0/+6
| | | | | | | | | | Now that we are able to build our own test modules, also allow to use cached modules so a) kernel headers are not required and b) distro maintainers are happy. It's still need a "--disable-test-modules" in the configure since the default is enabled. There's no license problems anymore since all modules come from our own repository, we ship the sources and the modules can be easily rebuilt.

* shared: avoid checking for __STDC_VERSION__Lucas De Marchi2015-02-261-0/+8
| | | | | | | | | | Since we pass -std=gnu99 to the compiler __STDC_VERSION__ is defined to 199901. Even in this case we can use _Noreturn. Delegate the testing to the configure phase with a compile test. In future we want to stop using AC_PROG_CC_99 and start using the new AC_PROG_CC from autoconf 2.70, which tries to choose the most recent standard.
* build: simplify and organize configureLucas De Marchi2015-02-261-18/+11
| | | | | | | | | | | - There's no need for the various AC_PROG_CC* macros - No need for AC_C_BIGENDIAN: the only place we care about endianness, we use __BYTE_ORDER - Organize calls to be in similar order as systemd - Disable --disable-largefile. We already had possible bugs in the index implementation if this were passed. It's now fixed, but it's never tested. Disable it. - Bump autoconf requirement to 2.64
* shared: add helper function to add and check for overflowLucas De Marchi2015-02-101-0/+2
| | | | | | | | | | Use _builtin_uaddll_overflow/_builtin_uaddl_overflow when available, abstracting the type to use it with uint64_t. Otherwise fallback to the implementation as added in 67466f2 ("Prevent offset + size overflow."). This also adds the tests for this new helper in the testsuite.
* build: check for required builtin functionsLucas De Marchi2015-02-101-0/+3
| | | | | | These builtins are implemented by both gcc and clang since a long time and we don't provide fallback for them. Let the configure phase check for them.
* Revert "build: enable LTO and _FORTIFY_SOURCE with optimization"Lucas De Marchi2015-01-261-11/+1
| | | | | | | This reverts commit 27bcc9111b63e94d091c3fa47e81fe52b806cd3e. Let the distro decide about this flag. It's relatively recent and doesn't work well with gcc 4.[678] making the testsuite to fail.

* build: Do not force diagnostics-color flagMike Auty2014-12-171-1/+0
| | | | | | | | | | The -fdiagnostics-color flag is only available on GCC >= 4.9, for older versions this could raise an error in certain circumstances (such as when using ccache). Instead, since -fdiagnostic-color=auto by default in gcc-4.9, simply set the required environment variable to the default one if it's undefined. Based mostly on the systemd commit f44541bc by Michal Schmidt.

* Add back-up implementation of be32toh()Randy MacLeod2014-09-291-0/+3
| | | | | | | | | | Older systems may not have the be32toh function defined. Check for this and fall back to checking the endianness and calling bswap_32 directly if needed. This works on both old and new systems.

| | | | | | | | | | | With -Wstrict-aliasing=2 we get the following warning: libkmod/libkmod-signature.c:124:20: note: in expansion of macro 'get_unaligned' sig_len = be32toh(get_unaligned(&modsig->sig_len)); However there's nothing wrong with it. modsig->sig_len is uint32_t and get_unaligned in this case returns uint32_t. There's notstrict aliasing violation.

* build: Allow disabling maintainer modeAnders Olofsson2013-11-101-0/+1
| | | | | | | | | | | | | | | | | This allows make rules for generated build files (i.e. configure, Makefile.in, ... ) to be skipped. This is useful when the source is stored without timestamps (for example in CVS or GIT). When the build rules trigger to regenerate the build files, it tries to use the same autotools version (currently 1.14) as was originally used for the release. Since many of our build machines run Debian Squeeze, they only have autotools 1.11 available and the build fails. Currently, we have to work around this by touching all the generated files before building to avoid triggering the make rule. With this patch, we would be able to just run configure with --disable-maintainer-mode instead. The patch sets the default to enable to not change the default behavior.
