* include/c: add errexec()Karel Zak2018-02-011-0/+6
| | | | | | | | | | | | | | | | The new errexec() macro consolidate and unify the way how util-linux tools react to failed exec()-like functions: * exit code 126 when program located, but not usable * exit code 127 when could not find program to exec The exit codes are compatible with coreutils. Note that all the change is located in c.h; the file exitcodes.h contains API specific (mkfs, fsck, ...) codes only.

* cal: Use ALTMON_* correctlyRafal Luzynski2018-01-221-0/+30
| | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | * Start the ISO format flags at bit 0 instead of bit 1. * Remove unnecessary _8601 from ISO format flag names to avoid line wrapping and to ease readability. * ISO timestamps have date-time-timzone in common, so move the TIMEZONE flag to bit 2 causing all timestamp masks to have the first three bits set and the last four bits as timestamp 'options'. * Change the 'SPACE' flag to a 'T' flag, because it makes the code and comments more concise. * Add common ISO timestamp masks. * Implement the ISO timestamp masks in all applicable code using the strxxx_iso() functions.

* lib/timeutils: add get_gmtoff()J William Piggott2017-11-101-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This new function returns the GMT offset relative to its argument. It is used in this patch to fix two bugs: 1) On platforms that the tm struct excludes tm_gmtoff, hwclock assumes a one hour DST offset. This can cause an incorrect kernel timezone setting. For example: Master branch tested with tm_gmtoff illustrates the correct offset: $ TZ="Australia/Lord_Howe" hwclock --hctosys --test | grep settimeofday Calling settimeofday(1507494204.192398, -660) Master branch tested without tm_gmtoff has an incorrect offset: $ TZ="Australia/Lord_Howe" hwclock --hctosys --test | grep settimeofday Calling settimeofday(1507494249.193852, -690) Patched tested without tm_gmtoff has the correct offset: $ TZ="Australia/Lord_Howe" hwclock --hctosys --test | grep settimeofday Calling settimeofday(1507494260.194208, -660) 2) ISO 8601 'extended' format requires all time elements to use a colon (:). Current invalid ISO 8601: $ hwclock 2017-10-08 16:25:17.895462-0400 Patched: $ hwclock 2017-10-08 16:25:34.141895-04:00 Also required by this change: login-utils/last.c: increase ISO out_len and in_len by one to accommodate the addition of the timezone colon.

* lib/timeutils: ISO_8601_BUFSIZ too smallJ William Piggott2017-11-101-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Although iso-8601 specifies years as 4 digits, it allows them to be wider. The current POSIX year width is limited by 'int tm_year' at 10 digits plus a negative sign. That, and the possibility of nanosecond time makes the widest POSIX iso-8601 time 41 characters. Plus the \0 string terminator yields a buffer size of 42.

* agetty: add support for /etc/issue.dKarel Zak2017-11-071-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | The /etc/issue file has been originally designed to inform users about the system (version, name, etc.). In last years is growing number of additional tools (containers, maintenance tools and interfaces, ...) and many admins and downstream maintainer want to add some tool specific hints to the issue file, but it mess to share one file between more packages and/or scripts. The solution is /etc/issue.d directory. The directory is extension to the standard system /etc/issue. The /etc/issue file has to exist, otherwise the directory will be ignored. It means "rm /etc/issue" (or --onissue) is still the way how keep our system silent independently on 3rd-party installed files in the /etc/issue.d directory. The content of the files in the directory are printed after content of the /etc/issue. The files are printed in version-sort order and .issue file extension is required (00-foo.issue 01-bar.issue ...). The change is backwardly compatible. Signed-off-by: Karel Zak <kzak@redhat.com>

* build: use --runstatedir instead of --localstatedirAndreas Henriksson2017-07-311-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The util-linux code was previously aligned to use @localstatedir@ and the util-linux build system was set to override the default to use /run. Current GNU Coding Standards introduced the @runstatedir@ variable for this purpose. Lets use that instead. The GNU default for @runstatedir@ is ${localstatedir}/run so util-linux still override the default to be /run to preserve the status quo from before. The only difference is that you'll now pass --runstatedir to override the location on the command line instead of --localstatedir. (FWIW, Debhelper in compat 11 will automatically start passing --runstatedir=/run to all autotools configured builds. It already passes --localstatedir=/var (to avoid it ending up with the GNU default /usr/local/var) which breaks the util-linux build system code that tries to default it to /run. This change will thus allow util-linux and debhelper to work better together and avoid the need for a package-specific override.) Relevant historic commits: * commit 07a16b9d1e5a48550a0d19abb9a900853433ffa2 "build-sys: change --localstatedir to /run" * commit 80c51185d50f00a2701f9379f10fc48a0f885dfc "uuidd: use run configured state directory" * commit 01c5b787947aeaffc7e56000827e3edefa357c59 "agetty: use configured run state directory" [kzak@redhat.com: - add $runstatedir fallback for autoconf < 2.70 - check for unmodified $localstatedir] CC: Sami Kerola <kerolasa@iki.fi> Signed-off-by: Andreas Henriksson <andreas@fatal.se> Signed-off-by: Karel Zak <kzak@redhat.com>
