Let's make sure "LimitCPU=30min" can be parsed properly, following the
usual logic how we parse time values. Similar for LimitRTTIME=.
While we are at it, extend a bit on the man page section about resource
limits.
Fixes: #1772
|
|
Let's not convert RLIM_INFINITY to "unsigned long long" and then back to
rlim_t, but let's leave it in the right type right-away.
Parse resource limits as 64 bit in all cases, as according to the man
page that's what libc does anyway.
Make sure setting a resource limit to (uint64_t) -1 results in a parsing
error, and isn't implicitly converted to RLIM_INFINITY.

Let's generate a simple error, and that's it. Let's not try to be smart
and record the last word that failed.
Also, let's make sure we don't compare numeric values with 0 by relying
on C's downgrade-to-bool feature, as suggested in CODING_STYLE.

specification of default time unit if none is specified
This is useful if we want to parse RLIMIT_RTTIME values where the common
UNIX syntax is without any units but refers to a non-second unit (µs in
this case), but where we want to allow specification of units.

The macro is generically useful for putting together search paths, hence
let's make it truly generic, by dropping the implicit ".d" appending it
does, and leave that to the caller. Also rename it from
CONF_DIRS_NULSTR() to CONF_PATHS_NULSTR(), since it's not strictly about
dirs that way, but any kind of file system path.
Also, mark CONF_DIR_SPLIT_USR() as internal macro by renaming it to
_CONF_PATHS_SPLIT_USR() so that the leading underscore indicates that
it's internal.

VIRTUALIZATION_CONTAINER_OTHER
If we don't know a container manager, we should consider it as "other"
rather than as no container manager at all, to provide a somwhat useful
upgrade path.

networkd: add support to configure IPv6 hop limit
|
|
conf-parser: use extract_first_word

|
lldp: avoid compiler warnings in lldp_tfl_package_read* functions
|

This patch adds support to configure IPV6 hop limit.
For example:
/proc/sys/net/ipv6/conf/wlp3s0/hop_limit

networkd: vxlan add option to set FDB entries

core/timer: in containers OnBootSec should count from container startup
|
|
core: support IEC suffixes for RLIMIT stuff
|
|
nspawn: support custom container service name
|
|
|
|
We were hardcoding "systemd-nspawn" as the value of the $container env
variable and "nspawn" as the service string in machined registration.
This commit allows the user to configure it by setting the
$SYSTEMD_NSPAWN_CONTAINER_SERVICE env variable when calling
systemd-nspawn.
If $SYSTEMD_NSPAWN_CONTAINER_SERVICE is not set, we use the string
"systemd-nspawn" for both, fixing the previous inconsistency.

journal: reduce minimum journal file size to 512 KiB
|
|
In Fedora dnf-makecache.timer specifies OnBootSec=10min, but it fired
during boot in systemd-nspawn, because the clock ticks since the host's
boot.
Fix it by treating OnBootSec the same as OnStartupSec when running in
a container.

* print '\n' on error
* use UDEVLIBEXECDIR (udev_rules_new uses it too)
|
|
|
|
For low end embedded systems 4 MiB for each journal file is a lot of
memory. Journald will use at least 512 KiB even if JOURNAL_FILE_SIZE_MIN is
set to less than that so just use 512 KiB.
|
|
Let's make things more user-friendly and support for example
LimitAS=16G
rather than force users to always use LimitAS=16106127360.
The change is relevant for options:
[Default]Limit{FSIZE,DATA,STACK,CORE,RSS,AS,MEMLOCK,MSGQUEUE}
The patch introduces config_parse_bytes_limit(), it's the same as
config_parse_limit() but uses parse_size() tu support the suffixes.

POSIX says:
The pthread_join() function shall not return an error code of [EINTR].
|
|
|
|
|
|
The S_ISREG test does not set errno, so don't use it in the error
message.
|
|
Use the "return log_error_errno(...)" idiom to have fewer curly braces.
The last hunk also fixes the return value of setup_journal(), but the
fix has no practical effect.
|
|
it would set errno only for an invalid address family.
Also fix a copy&paste error in one error string.
|
|
unlink() may change errno, so report the error from rename() first, then
unlink.
|
|
|
|
manpage says:
posix_fallocate() returns zero on success, or an error number on
failure. Note that errno is not set.
|
|
Our functions return negative error codes.
Do not rely on errno being set after calling our own functions.
|
|
pread() returns -1 on error and sets errno. Do not use the -1 as errno.
|
|
This replaces the use of ftell() with ftello() for 64-bit size on all
archs.
Also drops a pointless check for NULL before calling strbuf_cleanup().
|
|
write_catalog() use the hashmap only to get its size. The size is
already given in parameter 'n'.

core: parse socket port to extract_first_word
|
|
Some guests (ARM, AArch64, x86-RHEL) have 'KVM' in the product name.
Look for that first in order to more precisely report "kvm" when
detecting a QEMU/KVM guest. Without this patch we report "qemu",
even if KVM acceleration is in use on ARM/AArch64 guests.
I've only tested a backported version of this and the previous
patch on an AArch64 guest (which worked). Of course it would be
nice to get regression testing on all guest types that depend on
dmi done.
|
|
ARM/AArch64 guests now have SMBIOS tables populated (when boot
with a late enough QEMU and a late enough AAVMF is used as the
bootloader). Furthermore, when booting ARM/AArch64 guests with
ACPI, the DT detection obviously no longer works, so we need
dmi detection.
