* coredump: check cgroups memory limit if storing on tmpfsLuca Boccassi2021-06-081-1/+1
| | | | | | | | | | | | | | | | | | | | | | | When /var/lib/systemd/coredump/ is backed by a tmpfs, all disk usage will be accounted under the systemd-coredump process cgroup memory limit. If MemoryMax is set, this might cause systemd-coredump to be terminated by the kernel oom handler when writing large uncompressed core files, even if the compressed core would fit within the limits. Detect if a tmpfs is used, and if so check MemoryMax from the process and slice cgroups, and do not write uncompressed core files that are greater than half the available memory. If the limit is breached, stop writing and compress the written chunk immediately, then delete the uncompressed chunk to free more memory, and resume compressing directly from STDIN. Example debug log when this situation happens: systemd-coredump[737455]: Setting max_size to limit writes to 51344896 bytes. systemd-coredump[737455]: ZSTD compression finished (51344896 -> 3260 bytes, 0.0%) systemd-coredump[737455]: ZSTD compression finished (1022786048 -> 47245 bytes, 0.0%) systemd-coredump[737455]: Process 737445 (a.out) of user 1000 dumped core.
* man: remove some trailing whitespaceLennart Poettering2021-05-101-2/+2

* Clarify that these values are in bytesSteve Bonds2021-04-301-5/+10
| | | | Similar to `ProcessSizeMax`. The defaults in percentages can be misunderstood to mean the values for these parameters will be in percentages.

* tree-wide: drop quotes from around [section]Zbigniew Jędrzejewski-Szmek2020-07-061-1/+1
| | | | | | | For users, the square brackets already serve as markup and clearly delineate the section name from surrounding text. Putting additional markup around that only adds clutter. Also, we were very inconsistent in using the quotes. Let's just drop them altogether.
* man: use same header for all filesZbigniew Jędrzejewski-Szmek2019-03-141-2/+2
| | | | | | | The "include" files had type "book" for some raeason. I don't think this is meaningful. Let's just use the same everywhere. $ perl -i -0pe 's^..DOCTYPE (book|refentry) PUBLIC "-//OASIS//DTD DocBook XML V4.[25]//EN"\s+"http^<!DOCTYPE refentry PUBLIC "-//OASIS//DTD DocBook XML V4.5//EN"\n "http^gms' man/*.xml

* man: move all config file options to one sectionZbigniew Jędrzejewski-Szmek2019-02-131-1/+1
| | | | | | We had "SYSTEM MANAGER DIRECTIVES" which was a misnomer already, because it also listed user manager stuff. Let's make this a more general section and move the items for other services there too (from "MISCELANENOUS").
* man: drop mode line in file headersZbigniew Jędrzejewski-Szmek2018-07-031-1/+1
| | | | | This is already included in .dir-locals, so we don't need it in the files themselves.

| | | | | | | | | | | | | | | | | | | | | | | | Docbook styles required those to be present, even though the templates that we use did not show those names anywhere. But something changed semi-recently (I would suspect docbook templates, but there was only a minor version bump in recent years, and the changelog does not suggest anything related), and builds now work without those entries. Let's drop this dead weight. Tested with F26-F29, debian unstable. $ perl -i -0pe 's/\s*<authorgroup>.*<.authorgroup>//gms' man/*xml

* 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.
* man: fix ProcessSizeMax= description, describe how to disable coredumpsZbigniew Jędrzejewski-Szmek2018-05-171-3/+7
| | | | | | | | | | | | | | | | | | What the man page said was different than what the code did. save_external_coredump() will store the core temporarily for backtrace generation, and will delete if afterwards if it is too large. So to disable processing, it's necessary to both set Storage=none/Storage=journal+JournalSizeMax=0/Storage=external+ExternalSizeMax=0 and ProcessSizeMax=0. This updates the man page to reflect the code. The man pages are extended to describe that Storage=none + ProcessSizeMax=0 is the simplest way to disable coredump processing. All the storage and processing options make this quite complicated, so let's add a copy-and-pasteable example of how to disable coredump. Doing it through coredump.conf has the advantage that we still log, and the effect is immediate, unlike masking the sysconf file. Fixes #8788.
* 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.
* man: add a note where coredump default values areZbigniew Jędrzejewski-Szmek2018-01-201-0/+3
| | | | | I don't want to include all the default values in the man page because that's bound to get out of date…

* coredump: implement logging of external backtraces with --backtraceZbigniew Jędrzejewski-Szmek2017-02-141-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is useful for example for Python progams. By installing a python sys.execepthook we can store the backtrace in the journal. We gather the backtrace in the python process, and call systemd-coredump to attach additional fields (COREDUMP_COMM, COREDUMP_EXE, COREDUMP_UNIT, COREDUMP_USER_UNIT, COREDUMP_OWNER_UID, COREDUMP_SLICE, COREDUMP_CMDLINE, COREDUMP_CGROUP, COREDUMP_OPEN_FDS, COREDUMP_PROC_STATUS, COREDUMP_PROC_MAPS, COREDUMP_PROC_LIMITS, COREDUMP_PROC_MOUNTINFO, COREDUMP_CWD, COREDUMP_ROOT, COREDUMP_ENVIRON, COREDUMP_CONTAINER_CMDLINE). This could also be done in the python process, but doing this in systemd-coredump saves quite a bit of duplicate work and unifies the handling of various tricky fields like COREDUMP_CONTAINER_CMDLINE in one place. (Of course this applies to any other language which does not dump cores but wants to log a traceback, e.g. ruby.) journal entry: _TRANSPORT=journal _UID=1002 _GID=1002 _CAP_EFFECTIVE=0 _AUDIT_LOGINUID=1002 _SYSTEMD_OWNER_UID=1002 _SYSTEMD_SLICE=user-1002.slice _SYSTEMD_USER_SLICE=-.slice _SELINUX_CONTEXT=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 _BOOT_ID=1531fd22ec84429e85ae888b12fadb91 _MACHINE_ID=519a16632fbd4c71966ce9305b360c9c _HOSTNAME=laptop _AUDIT_SESSION=1 _SYSTEMD_UNIT=user@1002.service _SYSTEMD_INVOCATION_ID=3c4238d790a44aca9576ecdb2c7576d3 COREDUMP_UNIT=user@1002.service COREDUMP_USER_UNIT=gnome-terminal-server.service COREDUMP_UID=1002 COREDUMP_GID=1002 COREDUMP_OWNER_UID=1002 COREDUMP_SLICE=user-1002.slice COREDUMP_CGROUP=/user.slice/user-1002.slice/user@1002.service/gnome-terminal-server.service COREDUMP_PROC_LIMITS=Limit Soft Limit Hard Limit Units Max cpu time unlimited unlimited seconds Max file size unlimited unlimited bytes Max data size unlimited unlimited bytes Max stack size 8388608 unlimited bytes Max core file size unlimited unlimited bytes Max resident set unlimited unlimited bytes Max processes 15413 15413 processes Max open files 4096 4096 files Max locked memory 65536 65536 bytes Max address space unlimited unlimited bytes Max file locks unlimited unlimited locks Max pending signals 15413 15413 signals Max msgqueue size 819200 819200 bytes Max nice priority 0 0 Max realtime priority 0 0 Max realtime timeout unlimited unlimited us COREDUMP_PROC_CGROUP=1:name=systemd:/ 0::/user.slice/user-1002.slice/user@1002.service/gnome-terminal-server.service COREDUMP_PROC_MOUNTINFO=17 39 0:17 / /sys rw,nosuid,nodev,noexec,relatime shared:6 -

* coredump: remove Storage=both optionZbigniew Jędrzejewski-Szmek2016-09-281-10/+7
| | | | | | | | | | | | | | | | | | | | | | | Back when external storage was initially added in 34c10968cb, this mode of storage was added. This could have made some sense back when XZ compression was used, and an uncompressed core on disk could be used as short-lived cache file which does require costly decompression. But now fast LZ4 compression is used (by default) both internally and externally, so we have duplicated storage, using the same compression and same default maximum core size in both cases, but with different expiration lifetimes. Even the uncompressed-external, compressed-internal mode is not very useful: for small files, decompression with LZ4 is fast enough not to matter, and for large files, decompression is still relatively fast, but the disk-usage penalty is very big. An additional problem with the two modes of storage is that it complicates the code and makes it much harder to return a useful error message to the user if we cannot find the core file, since if we cannot find the file we have to check the internal storage first. This patch drops "both" storage mode. Effectively this means that if somebody configured coredump this way, they will get a warning about an unsupported value for Storage, and the default of "external" will be used. I'm pretty sure that this mode is very rarely used anyway.

| | | | | | | | | | | | | | | | | | | | | | | This did not really work out as we had hoped. Trying to do this upstream introduced several problems that probably makes it better suited as a downstream patch after all. At any rate, it is not releaseable in the current state, so we at least need to revert this before the release. * by adjusting the path to binaries, but not do the same thing to the search path we end up with inconsistent man-pages. Adjusting the search path too would be quite messy, and it is not at all obvious that this is worth the effort, but at any rate it would have to be done before we could ship this. * this means that distributed man-pages does not make sense as they depend on config options, and for better or worse we are still distributing man pages, so that is something that definitely needs sorting out before we could ship with this patch. * we have long held that split-usr is only minimally supported in order to boot, and something we hope will eventually go away. So before we start adding even more magic/effort in order to make this work nicely, we should probably question if it makes sense at all.
* man: generate configured paths in manpagesFilipe Brandenburger2015-05-281-4/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In particular, use /lib/systemd instead of /usr/lib/systemd in distributions like Debian which still have not adopted a /usr merge setup. Use XML entities from man/custom-entities.ent to replace configured paths while doing XSLT processing of the original XML files. There was precedent of some files (such as systemd.generator.xml) which were already using this approach. This addresses most of the (manual) fixes from this patch: http://anonscm.debian.org/cgit/pkg-systemd/systemd.git/tree/debian/patches/Fix-paths-in-man-pages.patch?h=experimental-220 The idea of using generic XML entities was presented here: http://lists.freedesktop.org/archives/systemd-devel/2015-May/032240.html This patch solves almost all the issues, with the exception of: - Path to /bin/mount and /bin/umount. - Generic statements about preference of /lib over /etc. These will be handled separately by follow up patches. Tested: - With default configure settings, ran "make install" to two separate directories and compared the output to confirm they matched exactly. - Used a set of configure flags including $CONFFLAGS from Debian: http://anonscm.debian.org/cgit/pkg-systemd/systemd.git/tree/debian/rules Installed the tree and confirmed the paths use /lib/systemd instead of /usr/lib/systemd and that no other unexpected differences exist. - Confirmed that `make distcheck` still passes.
