Lennart Poettering 686d13b9f2 util-lib: split out env file parsing code into env-file.c 
It's quite complex, let's split this out.

No code changes, just some file rearranging.
 2018-12-02 13:22:29 +01:00
Lennart Poettering 0a2152f005 util-lib: move open_serialization_fd() to serialize.c 
It definitely fits better there.

No code changes, just some rearranging.

Lennart Poettering e4de72876e util-lib: split out all temporary file related calls into tmpfiles-util.c 
This splits out a bunch of functions from fileio.c that have to do with
temporary files. Simply to make the header files a bit shorter, and to
group things more nicely.

No code changes, just some rearranging of source files.
 2018-12-02 13:22:29 +01:00
Lennart Poettering ee228be10c util-lib: don't include fileio.h from fileio-label.h 
There's no reason for doing that, hence simply don't.

Lennart Poettering 1d78890851 pager: log about all error conditions 
The code so far logged about some errors but was silent on others. Let's
stream-line that and make the function fully self-logging on all error
conditions.

Lennart Poettering 0672e2c6f8 tree-wide: use FORK_RLIMIT_NOFILE_SAFE wherever possible 
Similar to the previous commit: in many cases no further fd processing
needs to be done in forked of children before execve() or any of its
flavours are called. In those case we can use FORK_RLIMIT_NOFILE_SAFE
instead.
 2018-12-01 12:50:45 +01:00
Lennart Poettering 595225af7a tree-wide: invoke rlimit_nofile_safe() before various exec{v,ve,l}() invocations 
Whenever we invoke external, foreign code from code that has
RLIMIT_NOFILE's soft limit bumped to high values, revert it to 1024
first. This is a safety precaution for compatibility with programs using
select() which cannot operate with fds > 1024.

This commit adds the call to rlimit_nofile_safe() to all invocations of
exec{v,ve,l}() and friends that either are in code that we know runs
with RLIMIT_NOFILE bumped up (which is PID 1 and all journal code for
starters) or that is part of shared code that might end up there.

The calls are placed as early as we can in processes invoking a flavour
of execve(), but after the last time we do fd manipulations, so that we
can still take benefit of the high fd limits for that.
 2018-12-01 12:50:45 +01:00
Lennart Poettering 3c069cdac4 move src/shared/rlimit-util.[ch] → src/basic/ 
This is really basic stuff and in a follow-up commit will use it all
across the codebase, including in process-util.[ch] which is in
src/basic/. Hence let's move it back to src/basic/ itself.
 2018-12-01 12:50:45 +01:00
Lennart Poettering 1300f91149 rlimit: add new rlimit_nofile_safe() helper 
This helper sets RLIMIT_NOFILE's soft limit to 1024 (FD_SETSIZE) for
compatibility with apps using select().

The idea is that we use this helper to reset the limit whenever we
invoke foreign code from our own processes which have bumped
RLIMIT_NOFILE high.

Zbigniew Jędrzejewski-Szmek 652ef29887 path-util: allow NULLs in arguments to path_join() 
This removes the need to remember to put strempty() in places, thus reducing
the likelihood of a stupid mistake.

Lennart Poettering a22318e554 format-table: before outputting a color, check if colors are available 
This is in many cases redundant, as a similar check is done by various
callers already, but in other cases (where we read the color from a
static table for example), it's nice to let the color check be done by
the table code itself, and since it doesn't hurt in the other cases just
do it again.

Lennart Poettering ad5ffe3716 seccomp-util: drop process_vm_readv from @debug group 
it's already part of @ipc, no need to have it in both. Given that @ipc
is much more popular (as it is part of @system-service for example),
let's not define it a second time.

Zbigniew Jędrzejewski-Szmek 77c772f227 Move mount-util.c to shared/ 
libmount dep is moved from libbasic to libshared, potentially removing
libmount from some build products.
 2018-11-29 21:03:44 +01:00
Zbigniew Jędrzejewski-Szmek 049af8ad0c Split out part of mount-util.c into mountpoint-util.c 
The idea is that anything which is related to actually manipulating mounts is
in mount-util.c, but functions for mountpoint introspection are moved to the
new file. Anything which requires libmount must be in mount-util.c.

This was supposed to be a preparation for further changes, with no functional
difference, but it results in a significant change in linkage:

Lennart Poettering 30874dda3a dev-setup: generalize logic we use to create "inaccessible" device nodes 
Let's generalize this, so that we can use this in nspawn later on, which
is pretty useful as we need to be able to mask files from the inner
child of nspawn too, where the host's /run/systemd/inaccessible
directory is not visible anymore. Moreover, if nspawn can create these
nodes on its own before the payload this means the payload can run with
fewer privileges.
