namespace: unify limit behavior on non-directory paths
2016-07-19namespace: unify limit behavior on non-directory pathsAlessandro Puccetti
Despite the name, `Read{Write,Only}Directories=` already allows for regular file paths to be masked. This commit adds the same behavior to `InaccessibleDirectories=` and makes it explicit in the doc. This patch introduces `/run/systemd/inaccessible/{reg,dir,chr,blk,fifo,sock}` {dile,device}nodes and mounts on the appropriate one the paths specified in `InacessibleDirectories=`. Based on Luca's patch from https://github.com/systemd/systemd/pull/3327

2016-07-17basic/strv: add an extra NUL after strings in strv_make_nulstrZbigniew Jędrzejewski-Szmek
strv_make_nulstr was creating a nulstr which was not a valid nulstr, because it was missing the terminating NUL. This didn't cause any issues, because strv_parse_nulstr correctly parsed the result, using the separately specified length. But it's confusing to have something called nulstr which really isn't. It is likely that somebody will try to use strv_make_nulstr() in some other place, incorrectly. This patch changes strv_parse_nulstr() to produce a valid nulstr, and changes the output length parameter to be the minimum number of bytes which can be later on parsed by strv_parse_nulstr(). This allows the only user in ask-password-api to be slightly simplified. Based-on-patch-by: Jean-Sébastien Bour <jean-sebastien@bour.name> Fixes #3689.

2016-07-07basic: log: Increase static buffer for source file location (#3674)Daniel Mack
Commit d054f0a4 ("tree-wide: use xsprintf() where applicable") used a semantic patch approach to change a number of locations from snprintf(buf, sizeof(buf), FMT, ...) to xsprintf(buf, FMT, ...) The problem is that xsprintf() wraps the snprintf() in an assert_message_se(), so if snprintf() reports an overflow of the destination buffer, the binary will now terminate. This hit a user running a version of systemd that was built from a deeply nested system path. Fix this by a) Switching back to snprintf() for this particular case. We should really rather truncate the location string than crash in such situations. b) Increasing the size of that static string buffer, to make the event more unlikely.

2016-07-02basic/fd-util: introduce stdio_unset_cloexec() functionAlexander Kuleshov
There are some places in the systemd which are use the same pattern: fd_cloexec(STDIN_FILENO, false); fd_cloexec(STDOUT_FILENO, false); fd_cloexec(STDERR_FILENO, false); to unset CLOEXEC for standard file descriptors. This patch introduces the stdio_unset_cloexec() function to hide this and make code cleaner.

2016-06-24machined: "machinectl clean" can take a while, do it asynchronously from a ↵Lennart Poettering
background process This is a follow-up to 5d2036b5f3506bd0ff07042aee8d69c26db32298, and also makes the "machinectl clean" verb asynchronous, after all it's little more than a series of image removals. The changes required to make this happen are a bit more comprehensive as we need to pass information about deleted images back to the client, as well as information about the image we failed on if we failed on one. Hence, create a temporary file in /tmp, serialize that data into, and read it from the parent after the operation is complete.

2016-06-23build-sys: move fdset.[ch] src/basic → src/shared (#3580)Lennart Poettering
It makes use of the sd_listen_fds() call, and as such should live in src/shared, as the distinction between src/basic and src/shared is that the latter may use libsystemd APIs, the former does not. Note that btrfs-util.[ch] and log.[ch] also include header files from libsystemd, but they only need definitions, they do not invoke any function from it. Hence they may stay in src/basic.

2016-06-21resolved: when using the ResolveRecord() bus call, adjust TTL for caching timeLennart Poettering
When we return the full RR wire data, let's make sure the TTL included in it is adjusted by the time the RR sat in the cache. As an optimization we do this only for ResolveRecord() and not for ResolveHostname() and friends, since adjusting the TTL means copying the RR object, and we don#t want to do that if there's no reason to. (ResolveHostname() and friends don't return the TTL hence there's no reason to in that case)

2016-06-14util-lib: rework get_process_cmdline() (#3529)Lennart Poettering
This reworks get_process_cmdline() quite substantially, fixing the following: - Fixes: https://github.com/systemd/systemd/pull/3512/commits/a4e3bf4d7ac2de51191ce136ee9361ba319e106c#r66837630 - The passed max_length is also applied to the "comm" name, if comm_fallback is set. - The right thing happens if max_length == 1 is specified - when the cmdline "foobar" is abbreviated to 6 characters the result is not "foobar" instead of "foo...". - trailing whitespace are removed before the ... suffix is appended. The 7 character abbreviation of "foo barz" is hence "foo..." instead of "foo ...". - leading whitespace are suppressed from the cmdline - a comprehensive test case is added

Fix issue where IN6_ADDR_GEN_MODE_STABLE_PRIVACY is undefined but IFLA_INET6_ADDR_GEN_MODE is defined and thus the former does not get fixed in missing.h. This occurs with kernel headers new enough to have the IFLA_INET6_ADDR_GEN_MODE but old enough to not yet have IN6_ADDR_GEN_MODE_STABLE_PRIVACY (e.g. 3.18).

2016-06-12process-util: remove broken support for pid==0Zbigniew Jędrzejewski-Szmek
Our functions that query /proc/pid/ support using pid==0 to mean self. get_process_id also seemed to support that, but it was not implemented correctly: the result should be in *uid, not returned, and also it gave completely bogus result when called from get_process_gid(). But afaict, get_process_{uid,gid} were never called with pid==0, so it's not an actual bug. Remove the broken code to avoid confusion.
