* journal-remote: sync TrustedCertificateFile= parsing with journal-uploadFrantisek Sumsal2023-06-191-0/+1
| | | | | So we can use TrustedCertificateFile=- to disable certificate checking for both utilities.

* tree-wide: when in doubt use greek small letter mu rather than micro symbolLennart Poettering2023-06-141-1/+1
| | | | | | | | Doesn't really matter since the two unicode symbols are supposedly equivalent, but let's better follow the unicode recommendations to prefer greek small letter mu, as per: https://www.unicode.org/reports/tr25
* journal-remote: make writer_new() return negative errno on failureYu Watanabe2023-03-271-5/+4
| | | | | | | | | After f12b399dd6362a03379cb769954ebfb9972236ed, writer_new() may fail with non-OOM error. Let's return the error cause, and logs the failure in the caller side. This also drops logs in journal_remote_get_writer(), adds its caller typically logs the failure.
* tree-wide: use -EBADF for fd initializationZbigniew Jędrzejewski-Szmek2022-12-191-2/+2
| | | | | | | | | | | | | | | | -1 was used everywhere, but -EBADF or -EBADFD started being used in various places. Let's make things consistent in the new style. Note that there are two candidates: EBADF 9 Bad file descriptor EBADFD 77 File descriptor in bad state Since we're initializating the fd, we're just assigning a value that means "no fd yet", so it's just a bad file descriptor, and the first errno fits better. If instead we had a valid file descriptor that became invalid because of some operation or state change, the other errno would fit better. In some places, initialization is dropped if unnecessary.
* Rename def.h to constants.hZbigniew Jędrzejewski-Szmek2022-11-081-1/+1
| | | | | | The name "def.h" originates from before the rule of "no needless abbreviations" was established. Let's rename the file to clarify that it contains a collection of various semi-related constants.
* tree-wide: add a space after if, switch, for, and whileYu Watanabe2022-04-011-2/+2

* journal-file: merge compress/seal bool args into a single flags paramLennart Poettering2022-03-251-11/+14
| | | | | | | Just some modernization/refactoring. No change in behaviour, just let's do how we do things these days: use flags param instead of list of bools.
* journal: Rename JournaldFile to ManagedJournalFileDaan De Meyer2022-02-021-2/+2
| | | | | JournalFile and JournaldFile are hard to distinguish from each other. Let's use ManagedJournalFile instead to make the distinction more clear.
* journal: Introduce journald-file.c for journal file write related logicDaan De Meyer2021-12-061-8/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, all the logic related to writing journal files lives in journal-file.c which is part of libsystemd (sd-journal). Because it's part of libsystemd, we can't depend on any code from src/shared. To allow using code from src/shared when writing journal files, let's gradually move the write related logic from journal-file.c to journald-file.c in src/journal. This directory is not part of libsystemd and as such can use code from src/shared. We can safely remove any journal write related logic from libsystemd as it's not used by any public APIs in libsystemd. This commit introduces the new file along with the JournaldFile struct which wraps an instance of JournalFile. The goal is to gradually move more functions from journal-file.c and fields from JournalFile to journald-file.c and JournaldFile respectively. This commit also modifies all call sites that write journal files to use JournaldFile instead of JournalFile. All sd-journal tests that write journal files are moved to src/journal so they can make use of journald-file.c. Because the deferred closes logic is only used by journald, we move it out of journal-file.c as well. In journal_file_open(), we would wait for any remaining deferred closes for the file we're about to open to complete before continuing if the file was not newly created. In journald_file_open(), we call this logic unconditionally since it stands that if a file is newly created, it can't have any outstanding deferred closes. No changes in behavior are introduced aside from the earlier execution of waiting for any deferred closes to complete when opening a new journal file.

* tree-wide: mark set-but-not-used variables as unused to make LLVM happyFrantisek Sumsal2021-09-151-1/+1
| | | | | | | | | | | | | | LLVM 13 introduced `-Wunused-but-set-variable` diagnostic flag, which trips over some intentionally set-but-not-used variables or variables attached to cleanup handlers with side effects (`_cleanup_umask_`, `_cleanup_(notify_on_cleanup)`, `_cleanup_(restore_sigsetp)`, etc.): ``` ../src/basic/process-util.c:1257:46: error: variable 'saved_ssp' set but not used [-Werror,-Wunused-but-set-variable] _cleanup_(restore_sigsetp) sigset_t *saved_ssp = NULL; ^ 1 error generated. ```
* Drop the text argument from assert_not_reached()Zbigniew Jędrzejewski-Szmek2021-08-031-3/+3
| | | | | | | | | | | | | | | | | In general we almost never hit those asserts in production code, so users see them very rarely, if ever. But either way, we just need something that users can pass to the developers. We have quite a few of those asserts, and some have fairly nice messages, but many are like "WTF?" or "???" or "unexpected something". The error that is printed includes the file location, and function name. In almost all functions there's at most one assert, so the function name alone is enough to identify the failure for a developer. So we don't get much extra from the message, and we might just as well drop them. Dropping them makes our code a tiny bit smaller, and most importantly, improves development experience by making it easy to insert such an assert in the code without thinking how to phrase the argument.
* alloc-util: simplify GREEDY_REALLOC() logic by relying on malloc_usable_size()Lennart Poettering2021-05-191-5/+4
| | | | | | | | | | | | | | | | | | | | | | | | We recently started making more use of malloc_usable_size() and rely on it (see the string_erase() story). Given that we don't really support sytems where malloc_usable_size() cannot be trusted beyond statistics anyway, let's go fully in and rework GREEDY_REALLOC() on top of it: instead of passing around and maintaining the currenly allocated size everywhere, let's just derive it automatically from malloc_usable_size(). I am mostly after this for the simplicity this brings. It also brings minor efficiency improvements I guess, but things become so much nicer to look at if we can avoid these allocation size variables everywhere. Note that the malloc_usable_size() man page says relying on it wasn't "good programming practice", but I think it does this for reasons that don't apply here: the greedy realloc logic specifically doesn't rely on the returned extra size, beyond the fact that it is equal or larger than what was requested. (This commit was supposed to be a quick patch btw, but apparently we use the greedy realloc stuff quite a bit across the codebase, so this ends up touching *a*lot* of code.)
* tree-wide: use af_to_ipv4_ipv6() + af_from_ipv4_ipv6() helpers at various placesLennart Poettering2021-05-111-1/+2

* tree-wide: avoid uninitialized warning on _cleanup_ variablesLuca Boccassi2021-04-141-1/+1
| | | | | | | With some versions of the compiler, the _cleanup_ attr makes it think the variable might be freed/closed when uninitialized, even though it cannot happen. The added cost is small enough to be worth the benefit, and optimized builds will help reduce it even further.

* journal-remote: set a limit on the number of fields in a messageZbigniew Jędrzejewski-Szmek2019-01-091-0/+3
| | | | | | | | | Existing use of E2BIG is replaced with ENOBUFS (entry too long), and E2BIG is reused for the new error condition (too many fields). This matches the change done for systemd-journald, hence forming the second part of the fix for CVE-2018-16865 (https://bugzilla.redhat.com/show_bug.cgi?id=1653861).

* tree-wide: beautify remaining copyright statementsLennart Poettering2018-06-141-1/+1
| | | | | | Let's unify an beautify our remaining copyright statements, with a unicode ©. This means our copyright statements are now always formatted the same way. Yay.
* tree-wide: drop 'This file is part of systemd' blurbLennart Poettering2018-06-141-2/+0
| | | | | | | | | | | | | | | | This part of the copyright blurb stems from the GPL use recommendations: https://www.gnu.org/licenses/gpl-howto.en.html The concept appears to originate in times where version control was per file, instead of per tree, and was a way to glue the files together. Ultimately, we nowadays don't live in that world anymore, and this information is entirely useless anyway, as people are very welcome to copy these files into any projects they like, and they shouldn't have to change bits that are part of our copyright header for that. hence, let's just get rid of this old cruft, and shorten our codebase a bit.
* fuzz-journal-remote: allow fuzzer to be built without µhttpdZbigniew Jędrzejewski-Szmek2018-05-311-0/+4
| | | | | journal-remote still requires µhttpd, but things are easier if the fuzzer can be built without.

* journal-remote: split out µhttpd support and main() into a separate fileZbigniew Jędrzejewski-Szmek2018-05-311-1152/+54
| | | | | | | | | | | | | This is in preparation to reusing the RemoteServer in other concepts. I tried to keep changes to minimum: - arg_* global variables are now passed as state in RemoteServer - exported functions get the "journal_remote_" prefix - some variables are renamed In particular, there is an ugly global RemoveServer* variable. It was originally added because µhttpd did not allow state to be passed to the callbacks. I'm not sure if this has been remediated in µhttpd, but either way, this is not changed here, the global variable is only renamed for clarity.
* tree-wide: drop redundant _cleanup_ macros (#8810)Lennart Poettering2018-04-251-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | This drops a good number of type-specific _cleanup_ macros, and patches all users to just use the generic ones. In most recent code we abstained from defining type-specific macros, and this basically removes all those added already, with the exception of the really low-level ones. Having explicit macros for this is not too useful, as the expression without the extra macro is generally just 2ch wider. We should generally emphesize generic code, unless there are really good reasons for specific code, hence let's follow this in this case too. Note that _cleanup_free_ and similar really low-level, libc'ish, Linux API'ish macros continue to be defined, only the really high-level OO ones are dropped. From now on this should really be the rule: for really low-level stuff, such as memory allocation, fd handling and so one, go ahead and define explicit per-type macros, but for high-level, specific program code, just use the generic _cleanup_() macro directly, in order to keep things simple and as readable as possible for the uninitiated. Note that before this patch some of the APIs (notable libudev ones) were already used with the high-level macros at some places and with the generic _cleanup_ macro at others. With this patch we hence unify on the latter.
* tree-wide: drop spurious newlines (#8764)Lennart Poettering2018-04-191-2/+0
| | | | | | | | Double newlines (i.e. one empty lines) are great to structure code. But let's avoid triple newlines (i.e. two empty lines), quadruple newlines, quintuple newlines, …, that's just spurious whitespace. It's an easy way to drop 121 lines of code, and keeps the coding style of our sources a bit tigther.
* tree-wide: drop license boilerplateZbigniew Jędrzejewski-Szmek2018-04-061-13/+0
| | | | | | | | | | Files which are installed as-is (any .service and other unit files, .conf files, .policy files, etc), are left as is. My assumption is that SPDX identifiers are not yet that well known, so it's better to retain the extended header to avoid any doubt. I also kept any copyright lines. We can probably remove them, but it'd nice to obtain explicit acks from all involved authors before doing that.
* tree-wide: use TAKE_PTR() and TAKE_FD() macrosYu Watanabe2018-04-051-2/+2
|
* journal: provide compress_threshold_bytes parameterAlex Gartrell2018-03-201-2/+2
| | | | | | Previously the compression threshold was hardcoded to 512, which meant that smaller values wouldn't be compressed. This left some storage savings on the table, so instead, we make that number tunable.
* tree-wide: port various places over to use new rearrange_stdio()Lennart Poettering2018-03-021-7/+4
|
* log: minimize includes in log.hLennart Poettering2018-01-111-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | log.h really should only include the bare minimum of other headers, as it is really pulled into pretty much everything else and already in itself one of the most basic pieces of code we have. Let's hence drop inclusion of: 1. sd-id128.h because it's entirely unneeded in current log.h 2. errno.h, dito. 3. sys/signalfd.h which we can replace by a simple struct forward declaration 4. process-util.h which was needed for getpid_cached() which we now hide in a funciton log_emergency_level() instead, which nicely abstracts the details away. 5. sys/socket.h which was needed for struct iovec, but a simple struct forward declaration suffices for that too. Ultimately this actually makes our source tree larger (since users of the functionality above must now include it themselves, log.h won't do that for them), but I think it helps to untangle our web of includes a tiny bit. (Background: I'd like to isolate the generic bits of src/basic/ enough so that we can do a git submodule import into casync for it)
* process-util: add another fork_safe() flag for enabling LOG_ERR/LOG_WARN loggingLennart Poettering2018-01-041-2/+2
|
* tree-wide: introduce new safe_fork() helper and port everything overLennart Poettering2017-12-251-22/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | This adds a new safe_fork() wrapper around fork() and makes use of it everywhere. The new wrapper does a couple of things we previously did manually and separately in a safer, more correct and automatic way: 1. Optionally resets signal handlers/mask in the child 2. Sets a name on all processes we fork off right after forking off (and the patch assigns useful names for all processes we fork off now, following a systematic naming scheme: always enclosed in () – in order to indicate that these are not proper, exec()ed processes, but only forked off children, and if the process is long-running with only our own code, without execve()'ing something else, it gets am "sd-" prefix.) 3. Optionally closes all file descriptors in the child 4. Optionally sets a PR_SET_DEATHSIG to SIGTERM in the child, in a safe way so that the parent dying before this happens being handled safely. 5. Optionally reopens the logs 6. Optionally connects stdin/stdout/stderr to /dev/null 7. Debug logs about the forked off processes.
* tree-wide: make use of new STRLEN() macro everywhere (#7639)Lennart Poettering2017-12-141-1/+1
| | | | | Let's employ coccinelle to do this for us. Follow-up for #7625.
