* build-sys: improve hwclock CMOS dependencesKarel Zak2019-07-151-10/+9Star
| | | | | | | Let's use standard UL_* macros to check for dependencies (architectures and hwclock). Signed-off-by: Karel Zak <kzak@redhat.com>
* hwclock: use CMOS clock only if availableCarlos Santos2019-07-151-0/+13
| | | | | | | | | | | | - Add --disable-hwclock-cmos configuration argument - Add USE_HWCLOCK_CMOS (enabled by default for i386/x86_64) - Add define(USE_HWCLOCK_CMOS) - Compile hwclock-cmos.c only if USE_HWCLOCK_CMOS is true - Remove all unnecessary #ifdefs from hwclock-cmos.c - Add #ifdef USE_HWCLOCK_CMOS around the determine_clock_access_method() call in hwclock.c Signed-off-by: Carlos Santos <unixmania@gmail.com>
* build-sys: Include <stdlib.h> in ./configure wchar_t testFlorian Weimer2019-07-151-0/+1
| | | | | | | | Without #include <stdlib.h>, this configure check fails for strict C99/C11 compilers which do not support implicit function declarations (which are a C90 feature removed from C99). Signed-off-by: Karel Zak <kzak@redhat.com>

| | | | | | | | | | | | | | | | | It seems we need a way how to override the default pkg-config install directory. default: $ ./configure $ grep 'pkgconfigdir =' Makefile pkgconfigdir = ${usrlib_execdir}/pkgconfig user-defined: $ ./configure --with-pkgconfigdir=/usr/share/pkgconfig $ grep 'pkgconfigdir =' Makefile $ pkgconfigdir = /usr/share/pkgconfig Addresses: https://github.com/karelzak/util-linux/issues/793 Signed-off-by: Karel Zak <kzak@redhat.com>

* include/closestream: add close_stdout_atexit()Karel Zak2019-04-161-0/+2
| | | | | | | | It seems better to have a way to control when atexit(close_stdout()) is used, because close stdout means that for example ASAN (or another into binary integrated tool) is not able to print the final summary. Signed-off-by: Karel Zak <kzak@redhat.com>

| | | | | | | | | | | | | | | | | | | | The check tested whether code using crypt() links without -lcrypt, but didn't set have_crypt to yes if it succeeded. This fixes the check erroneously failing when compiling against musl libc. Signed-off-by: Johannes Nixdorf <mixi@shadowice.org>

| | | | | | | | | | | | | | | | We already default to /lib for the default $exec_prefix, but the current configure does not care about /lib64 although the use-case is exactly same as for /lib. Signed-off-by: Karel Zak <kzak@redhat.com>
* | su: add --whitelist-environmentKarel Zak2018-08-151-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * usable with --login to whitelist specified environment variables * the list is ignored for the core variables like HOME, SHELL, USER, LOGNAME and PATH (su --login always resets these variables) Note that su(1) requires password and after successful authentication user has full control over the session, so he can set arbitrary environment variables. The whitelist makes things more user friendly only. The patch removes unnecessary optimization when allocate environ[]. It seems better to keep all in glibc hands and just reset the environment array only. Addresses: https://github.com/karelzak/util-linux/issues/221 Signed-off-by: Karel Zak <kzak@redhat.com>

|/ | | | | | | | | | | | | | | | | libmount/python/pylibmount.c:158:19: warning: cast between incompatible function types from ‘PyObject * (*)(PyObject *)’ {aka ‘struct _object * (*)(struct _object *)’} to ‘PyObject * (*)(PyObject *, PyObject *)’ {aka ‘struct _object * (*)(struct _object *, struct _object *)’} [-Wcast-function-type] This is generic problem in all Python C code and gcc v8. The another possible (and probably more correct) way is to add unused argument to all API functions. Unfortunately, this solution is pretty invasive. The question is if gcc is not too paranoid in this case. For more details see https://bugs.python.org/issue33012. It seems Python guys also prefer CFLAGS modification for now.

| | | | | | | | | | | | | | | | | | | Nobody needs the .bz2 tarball. We dont't even upload it to kernel.org. BTW we fix dozens of these automake warnings: automake-1.13/am/ltlibrary.am: warning: 'libblkid.la': linking libtool libraries using a non-POSIX automake-1.13/am/ltlibrary.am: archiver requires 'AM_PROG_AR' in 'configure.ac' So we can remove -Wno-portability.

| | | | | | | | | | | cal: use ALTMON_* and _NL_ABALTMON_* constants to display months in a standalone form correctly. These constants have just been newly added to glibc. ALTMON_x has been used in BSD family since 1990s and has been accepted as the future POSIX extension. _NL_ABALTMON_* is exclusively a GNU extension but it is expected to be added to POSIX in future.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Linux network subsystem assigns an unique integer to a network namespace. term0# ip netns add UTIL-LINUX-LSNS-TEST-NS term0# ip netns list UTIL-LINUX-LSNS-TEST-NS term0# ip link add name lsns-vetha type veth peer name lsns-vethb term0 # ip link set lsns-vethb netns UTIL-LINUX-LSNS-TEST-NS term0# ip netns list UTIL-LINUX-LSNS-TEST-NS (id: 0) term0# ip link show dev lsns-vetha 230: lsns-vetha@if229: <BROADCAST,MULTICAST> mtu 1500 qdisc noop ... link/ether 3e:27:68:ba:b3:95 brd ff:ff:ff:ff:ff:ff link-netnsid 0 In this example 0 is assigned to UTIL-LINUX-LSNS-TEST-NS net namespace. The name, UTIL-LINUX-LSNS-TEST-NS, and it semantics is given and defined by iproute2 in userland; and nothing to do with util-linux. However, the id, 0, is managed in linux kernel. If lsns can show the ids, it helps users understand the state of network namespaces. This commit adds NETNSID column to the output. Here is an example of session: term0# ip netns exec UTIL-LINUX-LSNS-TEST-NS cat (Open another terminal) term1# ./lsns --type net NS TYPE NPROCS PID USER NETNSID COMMAND 4026531993 net 383 1 root unassigned /usr/lib/systemd/... 4026532433 net 1 1219 rtkit unassigned /usr/libexec/rtkit-daemon 4026532562 net 1 18201 root 0 cat 0 is shown as NETNSID for the cat process. For the initial name space, "unassigned" is printed. For the namespaces other type than net, "n/a" is printed. If an error occurred during getting the id, "n/a" is printed. Changes in V2: * Remove wrongly used & operators. * Make netnsid field empty if value for the column is not available. Suggested by Karel Zak. * Remove redundant condtion for checking the avaiablebility of netlink socket. Suggested by Karel Zak. Signed-off-by: Masatake YAMATO <yamato@redhat.com>
* build-sys: add --enable-asan and --memcheck-asan for testsKarel Zak2017-11-231-0/+11
| | | | | | | | | The command ./configure --enable-asan adds -fsanitize=address to the compiler command line. In the regression tests leaks detection is disabled by default. You have to use --memcheck-asan on test command line to enable. Signed-off-by: Karel Zak <kzak@redhat.com>
* libmount: use eacess() rather than open() to check mtab/utabKarel Zak2017-10-201-0/+1
| | | | | | | | | The open() syscall is probably the most strong way how to check write accessibility in all situations, but it's overkill and on some paranoid systems with enabled audit/selinux. It fills logs with "Permission denied" entries. Let's use eaccess() if available. Signed-off-by: Karel Zak <kzak@redhat.com>
